Abstract: The concentrations of PCDDs, PCDFs, and DL-PCBs were determined in samples of eight commonly used medicinal plants, namely "caraway, cumin, anise, sage, rosemary, black tea, ginger and cinnamon" collected randomly from the Jeddah central market between the periods of July and August 2013. Fortunately the result revealed that, the collected samples are free of PCDDs, PCDFs, and DL-PCBs. While, Among the determined heavy metals, the maximum concentration of Fe and Pb were recorded in rosemary (846.2 ± 18.5 and 10.8 ± 0.12 mg.kg-1 respectively), it is noticeable that, the maximum Pb concentration (10.8 ±0.12 mg.kg-1) in the medicinal plant recorded in Rosemary, followed by 1.3 ± 0.02 mg.kg-1 in black tea with a significant gab. While the maximum concentrations 0f Zn and Cr were recorded in anise (52.7 ± 1.6 and 3.1 ± 0.1 mg.kg-1 respectively). In contrast to the above, cinnamon characterized by the minimum concentration (0.89 ± 0.03, 19.5 ± 1.5, 13.1 ± 1.1 , 0.012 ± 0.001 , and <LOQ mg.kg-1 )for six of the recorded eight heavy metals (Cu, Fe, Zn, Ni, Hg and Pb respectively). The study give a good indication about the absence of PCDDs, PCDFs, and DL-PCBs from the collected plants, but on the other hand it sheds light on the importance of follow-up the heavy metals concentration in these commonly used plants.

Abstract: There is a great increase risk of developing renal cell carcinoma (RCC) in post-transplanted patients, mainly attributed to the immunosuppression. The majority of these RCC are developing in the native kidneys rather than the allograft of the renal transplant recipients, and the most common histological variant is clear cell carcinoma. Chromophobe renal cell carcinoma is a rare subtype of renal epithelial carcinoma with distinctive histological and immunohistochemical features and associated with good prognosis. Chromophobe renal cell carcinoma occurrence in allograft kidney in renal transplant recipients is extremely uncommon. One case of chromophobe renal cell carcinoma has been reported in 13.5-years-old boy who is a living-related kidney transplant recipient. We reported an exceptionally rare case of chromophobe renal cell carcinoma in allograft kidney in 52-years-old women, 15 years post living-unrelated renal transplant along with chronic hepatitis C infection. The tumor was discovered incidentally during routine ultrasound evaluation. The tumor revealed the typical histological and immunohistochemical features of chromophobe renal cell carcinoma.

Abstract: This paper presents the potential significant factors of urban poverty among the minority Indian community in Malaysia through community development practice. Preliminary study was conducted at Lembah Pantai which is a well known urban squatters destination in Kuala Lumpur, Malaysia. In-depth interview which was used as the qualitative data collection method helped the researchers to holistically understand the community status, issues which can influence urban poverty. Apart from that community development domains such as participation, empowerment and capacity building are also highlighted in the study. This study reveals that the community is still facing many problems. They also argue that the developmental programs by the government are carried out by not empowering the community. However, the community feels that their problems can be solved if the community can be free of alcoholism and gangterism. It is hoped that the findings of this study will contribute to existing literature in urban poverty ground that could be an addition to the social capital theory current standing.

Abstract: This paper explores the origin and development of Siddha philosophy in the context of Malaysian Indian culture. Although the development of Siddha philosophy has been written by several scholars in the context of South India, hardly any studies are found outside India. Scant literature is available on Siddha philosophy from Malaysia; and any related literatures found are generic in nature and not in-depth. Therefore the purpose of this paper is to expand the literatures on the Malaysian Siddha philosophy which is becoming relevant in the Malaysian Indian culture focussing on Tamil Siddhas. The methodology employed for this paper is qualitative in nature and it includes inputs gathered on Siddha philosophy and Siddhars from various discussions held with many scholars at conferences, Siddha practitioners in Malaysia and a review of the existing literatures on Siddha philosophical traditions. This paper is to be considered as the first to explore the current development of Siddha philosophy among the Indians in Malaysia.

Abstract: Microbial fructosyltransferases (levansucrases) are polymerases that are involved in microbial fructan (levan, inulin and fructo-oligosaccharide) biosynthesis. Levan has potential importance in food, pharmaceutical, medicine, cosmetics and textile industry. Structurally, microbial fructosyltransferase proteins share the catalytic domain of glycoside hydrolases 68 family and are grouped in seven phylogenetically related clusters. The aim of the work was screening the potency of some bacterial isolates to produce extracellular levansucrase. Bacteria were isolated from different sources (oral swab, spoiled milk, spoiled whey, and spoiled yoghurt). Pediococcus acidilactici showed the highest levansucrase activity after 2 days fermentation under shacking condition yielding (12.64 U/ml), and maximum levan production (15.4 g/L). Following the optimization of carbon source, nitrogen source, temperature and initial pH of the growth medium in submerged liquid cultures. In fact, All carbon sources induced the production of levansucrase activity, but sucrose at 30% (w/v) was the most efficient inducer. The optimal temperature and pH of the levansucrase were 30°C and 6.0, respectively. The crude levansucrase of Pediococcus acidilactici extract was enriched using selected precipitating agents. The results show that ethanol (65% saturation), provided the highest purification factor of 3- fold with a recovery yield of 41.05% as a total highest recovered protein. The optimum reaction temperature and pH of semi purified levansucrase were 40°C, 5.2 respectively. Analysis of the partial purified enzyme preparation by SDS–PAGE revealed one protein band showing levansucrase activity, The molecular weight of this band was estimated to be around 50.000 Daltons.

Abstract: Conveyer belts with pretension are a striking example of machines containing blocks (components) with initial stress. Pretension is necessary for passing pulling power by drive pulley, and also for restricting of belt sagging between the roller carriages. The problems about vibrations of the conveyer belt under the influence of longitudinal and transverse forces have been studied. Information on determination of critical speed of belt movement and frequencies of its transverse vibration [1] has been stated; Influence on the values of the above stated parameters of geometrical and physical characteristics of the belt used in numerical methods of the amplitude-frequency characteristic of vibration of the conveyer belt has been considered. Determination of flexural stress in a conveyer belt is one of the major problems which solving is necessary for determination of reliability and durability of a conveyor belt.

Abstract: The present study aimed at investigating the effects of spatial and environmental factors on plant species richness in Farasan Archipelago, Saudi Aarbia. The principal coordinates of neighbor matrices (PCNM) technique was used to identify the spatial variables (PCNM vectors). The PCNM produced 9 eigenvectors and only two vectors were positive and significant based on the forward selection procedures. Similar forward selection technique, based on the two stopping criteria, was also employed to determine the most important environmental variables controlling the plant species richness. Among the 13 environmental variables investigated, only 6 variables were retained after forward selection that controlling species richness in Farasan Archipelago. These selected parameters, arranged according to their importance, were altitude, electrical conductivity (EC), calcium (Ca), sodium (Na), calcium carbonate (CaCO3) and organic matter (OM). The variation partitioning technique was employed to examine the relative importance of environmental and spatial factors to the plant species richness.  The selected environmental parameters (altitude, EC, Ca, Na, CaCO3 and OM explained 26.3% of the total variance in species richness. However, the two selected spatial variables (PCNM vectors) explained only 4.2% of the richness variation. On the other hand, the spatially-structured environmental variables (shared fraction) explained 5.6 % of the total variance in plant species richness.  The present study revealed that the environmental variables (altitude and soil chemistry) are the most important factors regulating the species richness in Farasan Archipelago. However, the spatial variables showed to be less important in shaping the diversity patterns of plants in Farasan Archipelago.

Abstract: Background: Recent evidence links the pathophysiology of asthma to cardiovascular diseases. A pro-atherogenic role of leukotrienes has been reported which is suggestive of a potential anti-atherosclerotic effect for leukotriene antagonists. Retrospective observations suggest that inhaled corticosteroids may reduce atherothrombotic mortality by altering systemic inflammation. Aim: the present study was designed to investigate the impact of the leukotriene antagonist montelukast on vascular dysfunctions in guinea pigs exposed to chronic ovalbumin (OVA) challenge and fed high fat diet (HFD). The potential anti-atherosclerotic effects of montelukast were compared to those of the inhaled corticosteroid fluticasone.  Method: Forty-eight male guinea pigs were divided into: control non-asthmatic-chow fed (n=6), non-asthmatic-dyslipidemic; fed HFD (n=6), asthmatic-chow fed (n=18), and asthmatic-dyslipidemic groups (n=18), the last 2 groups were further subdivided into 3 groups (n=6 each): vehicle treated, montelukast- treated (10mg/kg orally) and fluticasone- treated (100µg/2ml of 0.1%ethanol PBS by inhalation) groups. Anti-asthma and Anti-atherosclerotic effects of the tested drugs were assessed. Results: Chronic OVA challenge induced atherogenic vascular changes, compared to control and potentiated the vascular dysfunctions induced by HFD in asthmatic dyslipidemic animals. Conversely, feeding animals a HFD resulted in airway inflammation and remodeling with hyper-responsiveness. Montelukast, exhibited anti-atherosclerotic effects (significant increase in % Ach-induced relaxation and phenylephrine (PhE) EC50 with reduction of PhE E-max in isolated aortic rings) of asthmatic dyslipidemic animals. These changes were associated with reduction of aortic mast cell infiltration and intima/media ratio together with a reduction in airway remodeling and mast cell infiltration. Fluticasone induced a lesser reduction in mast cell infiltration in vascular tissue as well as in the airways with lack of anti-atherosclerotic effects and reduced effects on airway remodeling. Conclusion: The anti-atherosclerotic potentials of montelukast observed implicate leukotrienes released from mast cells as possible inflammatory mediators linking asthma, obesity and atherosclerosis. The effects of montelukast may be the result of a direct effect on the vasculature as well as an indirect effect on airway remodeling through a crosstalk (involving mast cells and leukotrienes) between the airway and vascular tissue. Targeting excess leukotrienes by leukotrienes modifiers rather than by corticosteroids in dyslipidemic asthmatics might provide better control of their airway disorder as well as a reduction in the risk of atherosclerosis.

Abstract: Finding the textual contents in images is a challenging and promising research area in information technology. Consequently, text detection and recognition in multimedia had become one of the most important fields in computer vision due to its valuable uses in a variety of recent technical applications. In this paper, we propose an improved text detection technique which starts with employing image enhancement to remove small and thin lines from the background and to increase the contrast on the text region. The resulted enhanced image passes next into a set of morphological operations for edge extraction; later, text candidates are labeled, and Hough transform is applied for text extraction at the end of the process. The effectiveness of the algorithm is tested quantatively and qualitatively under a set of scene images from KAIST dataset. The results show that the proposed technique is robust in detecting the text from scene images with high average of Precision, Recall, and F-Score which are 88.1%, 96%, and 91.5%, respectively.

Abstract: Migratory processes became more active in connection with a difficult economic situation in the country, with acquisition of independence by Kazakhstan, and also with transition to the market relations in all territory of the CIS. This is expanded possibilities of return on the historical homeland by separate ethnic groups. Aggravation of migratory outflow during the period about 1991-1995 defined need for identification of qualitative structure for the migrating population. There is very topical inflow of repatriates (oralmans) along with these problems). In such cases the migration service experiences difficulties connected with mood of repatriates. More of them refuse to stand on the account at the employment service for retrainings and obtaining of nationality,  participation in public works, creation of normal vital conditions, provision of housing and their employment. Repatriates have heavy adaptation which aggravate a labor market even more deeply. It is demands integrated approach to the migration analysis in deal with a feature of development of migratory processes in the republic. Article are presented results of the statistical review and sociological research of the socio-economic factors causing migratory behavior of repatriates (oralmans). Also the portrait of the potential migrant is revealed and extent of influence of labor migration on a labor market is defined.

Abstract: The chemical analysis of 44 groundwater samples in the northern Bangladesh has been evaluated to determine the hydrogeochemical processes and major ions, heavy and rare metal concentration for its suitability for agricultural and domestic purposes. The quality analysis is performed through the estimation of pH, EC, cations (Ca2+, Mg2+, Na+, K+, Zn2+, Cu2+, Mn2+, Fe3+ and As3+), anions (CO32-, HCO3-, NO3-, SO42-, PO43- and Cl-) and TDS (total dissolved solids). We also computed several variables such as SAR (sodium adsorption ratio), SSP (soluble sodium percentage) RSC (residual sodium carbonate), potential salinity, permeability index, Kelly's ratio, Gibbs ratio and hardness to evaluate the suitability of groundwater supply for specific uses. From the geochemical results, it has been found that both the cations and anions varied in the groundwater. Among the chemical budget of ions, magnesium and chloride were found to be the most predominant ions. The intense agricultural activities may be an important factor for the higher concentration of nitrates in these aquifers. Based on the total hardness, most groundwaters are moderately hard. According to EC and SAR the most dominant class is C1-S1. The major ion concentrations are below the acceptable level for drinking water. The salinity hazard is low thus, there is less chances to increase of toxic salt concentrations. Gibbs diagram indicates that all the samples fall in the precipitation dominance field. Regarding cation and anion constituents, groundwater is suitable for irrigation and drinking purposes except of few wells.

Abstract: Thalictrum coreanum (Ranunculaceae), an endangered herb in South Korea, and widespread T. ichangense are congeneric species with similar morphologies and life forms. Currently, there is a debate about the identification and distribution of these two species. We carried out a comparative analysis of the genetic variability of these two species using random amplified polymorphic DNA (RAPD) markers. Genetic diversity at species level was high, but lower at the population level. Analysis of molecular variance (AMOVA) appeared to moderate genetic differentiation among the species. In the total variance of T. coreanum, 54.53% was attributable to among populations and 45.66% to within populations. On the other hand, 35.24% of the total variance was due to among populations, while 64.76% was due to the within populations of T. ichangense. Our results for T. coreanum and T. ichangense showed a high commonality at the genetic level. T. coreanum appeared to have a genetic diversity at a similar level to T. ichangense. In the AMOVA and Principle Coordinate Analysis (PCoA), however, T. coreanum cleary distinguished with T. ichangense. To secure and preserve an endangered species, systematizing species information should be prioritized, according to the accurate criteria. Therefore, the use of a molecular marker such as RAPD could provide hints, diminishing the uncertainty of the distribution area and the identification of these two congeneric species.

Abstract: Agricultural residues can be converted in the biofuels to fulfil the world energy demands and achieve the targets set by different countries to replace fossil fuels with renewable resources. Fast pyrolysis of cotton stalk, obtained from agriculture fields of Punjab, Pakistan, is being investigated. A Lab Scale bubbling fluidized bed fast pyrolysis system is designed and fabricated. The operating parameters of the fluidized bed reactor are selected on the basis of the study of hydrodynamics of cold model and TGA analysis. Experiments are conducted over a range of operating conditions. Yield of char and gases are measured. The products are analyzed on FTIR and GC-MS to investigate the functional groups and compounds present in the pyrolysis liquid derived from the cotton stalks. GC-MS analysis of pyrolysis liquid has shown number of peaks with the compounds identified as acetone, benzene, 3-methyl pentane, 2,2-dimethylbutane, 3,5- dimethyloctane, 2-methylhexanoic acid, 1,2- benzene dicarboxylic acid, Bis (2-ethylhexyl) phthalate whereas GC analysis of exhaust gas has shown three peaks containing gases H2, CO2 and n-butane. Effect of temperature is investigated on the yield of char and the no. of compounds present in the pyrolysis of liquid along with their functional groups.

Abstract: The aim of this cross-sectional study was to evaluate cephalometric characteristics of Saudi growing children with Class II and III malocclusions. Methods: The sample consisted of 135 Saudis (63 boys and 72 girls with a mean age of 12.4 years). The sample was selected from patients who were seeking orthodontic treatment at the Faculty of Dentistry, King Abdulaziz University, Jeddah, Saudi Arabia. The control group consisted of cephalometric records of 55 patients with normal occlusion (23 boys and 32 girls, mean age = 12.3). Comparisons of linear and angular measurements were performed using lateral cephalograms. Results: ANOVA for the total sample showed that there were no significant differences in the skeletal measurements between Class I, II and III malocclusions except in SNA, ANB, Wits, angle of convexity, maxillary length and total face height, p<0.001. For boys, ANOVA showed similar results except that the total face height was not different and the maxillary/mandibular ration was significantly different, p <=0.002. For girls, ANOVA was only significant in SNA, ANB, Wits and angle of convexity, p <0.001. There were significant differences between Class I, II and III in all dental readings except for the interincisal angle and SN to upper incisor angle. For boys’ analysis, ANOVA showed that only upper incisor position and inclination and lower incisor inclination were significantly different. Dental measurements for the girls were significantly different amongst the three classes except for the interincisal angle, upper incisor to SN and NA angles. Soft Tissue Analysis showed that a significantly different readings between the three classes of malocclusions.  However, in the boys reading the lower lip to E-plane was similar between the classes.  For girls, only the reading for the soft tissue convexity was significantly different. Conclusion: maxillary deficiency and protrusion is the cause of Class II and III, respectively due to the differences in length of the maxilla. Maxillary incisors are proclined and protruded while the mandibular incisors are retroclined and retruded in Class III. Cephalometric characteristics differ between genders for all three classes of malocclusion.

Abstract: We examined the fluctuating asymmetry (FA) in larvae of two Odonata genera; Pseudagrion sp. (Zygoptera: Coenagrionidae) and Onychothemis sp. (Anisoptera: Libelulidae) living in a relatively polluted river as a tool for water quality assessment. Larval and water samples were collected monthly from January to June 2008. Various water parameters including pH, temperature, velocity, nitrate, phosphate, biochemical oxygen demand (BOD), chemical oxygen demand (COD), total suspended solid (TSS), and ammonium-N content were recorded. Composite effect of selected water parameters expressed as Water Quality Index (WQI) was also calculated. FA indices [(FA), absolute asymmetry (AbsFA), composite fluctuating asymmetry (CFA)] of the first and second antennal segments of Onychothemis sp. and and last tarsal segment of Pseudagrion sp. hind legs were calculated. We found that high FA levels in the selected traits for the two Odonata species were associated with deterioration in the water quality (WQI). BOD and pH were positively correlated with high FA indices in the antennal segments of Onychothemis sp. The FA levels calculated as FA indices of last tarsal segment of Pseudagrion sp. hind legs were positively correlated with ammonium-N, phosphate, and COD. We concluded that selected traits of the odonate taxa are useful bioindicators as the incidence of fluctuating asymmetry in their larvae was strongly associated with deterioration in the water quality of the river.

Abstract: The aim of this study was to investigate intra-specific variability among three geographical sources in fruit morphology and seed chemical composition. Morphological traits of various fruit layers (epicarp, mesocarp, endocarp and kernel) were measured. Seed kernel was analyzed for oil, saponin, protein, macro (Ca, Mg, Na, K, P) and micro (Fe, Mn, Zn, Co, Cu) nutrients. Endocarp wood was characterized for (specific gravity, gross heat of combustion, ash content and biocarbon yield). Biocarbon volatile matter, fixed carbon and ash contents were determined. The seed kernel contained high oil, saponin and minerals that were significantly differed among sources. The protein was not significantly different among sources Endocarp revealed good properties and relatively high biocarbon yield. There was observed relationship between sources with morphological and chemical properties. Damazin source (dark cracking clay) showed higher saponin, woody portion and biocarbon yield, while Hada Alsham source (lighter soil) had higher pulp content. The high contents in most of seed kernel constituent's highlights the suitability of Balanites for very wide range of products and the remaining woody part can be used for potential biocarbon products. Whereas the high variability observed among sources, indicates the importance of considering suitable sources for domestication.

Abstract: Background: Lead is one of the environmental pollutants of high risk to public health. In this study we tried to find if there is a relationship between blood lead level and cardiac function after myocardial ischemia reperfusion injury. In addition, this study tried to evaluate the effect of ascorbic acid [vitamin C (VC)] on cardiovascular parameters in the lead-exposed rats. Methods: Twenty four Wister male rats (initially weighing 150 to 170 gm) were divided into three groups; Group I (Control rats) was given distilled water every day. Group II (lead-exposed rats) received orally lead acetate solution (60mg/kg body weight), once daily. Group III (lead-exposed + VC-treated rats) received lead acetate 60 mg /kg, once daily and concurrently supplemented with Vitamin C, 40mg/kg, every other day. Water, lead and vitamin C were all administered by using intra-gastric intubation for 8 weeks. All rats were subjected to an in vivo measurement of arterial blood pressure, ECG recording, blood samples collection for determination of lead content in the blood, blood picture, plasma total cholesterol, and HDL, in addition, atherogenic index was calculated. In vitro study of isolated hearts to record the intrinsic activity of the heart under baseline condition, responses of the heart to ischemia and reperfusion and determination of cardiac weights. Also glutathione peroxidase activity, and malondialdehyde level were measured in the cardiac tissue. Results: Lead exposure increased the concentration of lead in the blood from the pre-exposure level of 2.07 ±0.52μg/dl to 25.24 ±1.86 μg/dl after 8 weeks of exposure in lead-exposed rats. In addition, plasma total cholesterol was significantly increased together with reduction in plasma HDL, both values nearly reversed with the administration of vitamin C. Also decreased level of the MDA and increasing glutathione peroxidase activity in cardiac tissue were observed in lead exposed group. RBCs count, hemoglobin content, Haematocrite value, mean corpuscle volume (MCV), mean corpuscle hemoglobin (MCH), of lead exposed animals were significantly decreased, as compared to control rats. Vitamin C attenuated these hematological changes. ECG showed shortened the QT interval with significant increase in QRS voltage in lead exposed rats. Significant elevation of arterial blood pressure was observed in lead exposed rats as compared to control rats, As regards isolated heart perfusion, baseline chronotropy and inotropy were increased, but myocardial flow rate decreased in lead exposed rats. Vitamin C administration diminished the cardiac toxicity of lead as it normalized the mean arterial pressure, QT interval, as well as, HR regarding the baseline values and after 30 minutes of ischemia reperfusion. Conclusion: chronic Lead exposure has toxic effects which disturb the heart function, while natural antioxidant (Vitamin C) may be preferable in reducing Lead toxicity in the exposed rats, suggesting that lead chelating agents having antioxidant properties are preferred in treating cardiovascular disorders accompanying lead toxicity.

Abstract: The article presents the results of many years’ field research of small-numbered indigenous peoples of the North and Siberia, resident in the territory of Krasnoyarsk Region (the Russian Federation). At the present time small-numbered indigenous peoples of Krasnoyarsk Region (the Evenks, Enets, Chulyms, Nganasans, Nenets, Selkups, Kets, Dolgans) are exposed to serious influence of modernization and global transformations. Ethnogeny and culture genesis processes are not the same for these ethnocultural groups. Some post-Soviet cultural practices support formation of a positive ethnocultural identity of indigenous peoples of the North and Siberia. Museumization of the Nganasan culture (an indigenous Siberian people resident only in Krasnoyarsk region) confirms the conclusion that Taymyr Neo-Shamanism is significantly different from the Shamanism of archaic and traditional cultures. Museumization of the Nganasan cultural heritage points out that the culture experiences a strong impact of modern market mechanisms. True Shamanism is no longer typical of the ethnocultural identity of the Nganasans.

Abstract: Epilepsy as well as chronic use of most antiepileptic drugs, particularly in children, predisposes to cognitive impairment. The brain is considered abnormally sensitive to oxidative stress and damage which observed during seizure activity. Omega-3 (OM3) fatty acids are known antioxidants that play a role in nervous system activity, cognitive development, memory-related learning, and synaptic transmission. Aim: The aim of the present study was to investigate the protective effects of OM3 on cognitive impairment after development of seizures and corresponding oxidative stress and neuronal DNA damage in young pentylenetetrazole (PTZ)-kindled rats. Methods: The effect of pretreatment with OM3 (200, 300 and 500 mg/kg, orally) on PTZ-induced kindling, corresponding cognitive impairment, using passive avoidance test, hippocampal oxidative stress. Furthermore, the corresponding changes in hippocampal 8-hydroxy-2′-deoxyguanosine (8-OHdG) were measured. Results: PTZ, (30 mg/kg, i.p.) once every alternate day induced kindling in rats after 31.0±1.4 days. OM3 showed dose-dependent anti-seizure effect. OM3 significantly increased the latency to myoclonic jerks, clonic seizures as well as generalized tonic-clonic seizures, and decreased the number of myoclonic jerks. PTZ kindling induced a significant oxidative stress and cognitive impairment which was reversed by pretreatment with OM3 in a dose-dependent manner. In addition, hippocampal 8-OHdG levels were significantly reduced by OM3 in PTZ kindled rats. Conclusions: OM3 ameliorates seizures, cognitive impairment, oxidative stress and hippocampal DNA damage in PTZ kindled rats. These results thus suggest the potential of OM3 as an adjuvant in epilepsy both to prevent seizures as well as to protect against seizure induced memory impairment.

Abstract: In spite of being economically and socially rewarding, medical professions are medically and socially debilitating. Therefore; this study aimed to evaluate the impact of medical profession strain on cardiovascular diseases risk factors in an Egyptian cohort of medical graduates in ten years period. A total of 92 medical graduates were subjected to interview questionnaire and medical examination and investigations of CVDs risk factors in 2001 as a baseline and ten years later in the evaluation phase. By the end of the evaluation phase of the study the results showed that the mean values of body mass index, systolic and diastolic blood pressure, fasting blood sugar, total cholesterol and stress hormones e.g., cortisol, adrenaline and nor-adrenaline were significantly increased in 2011 than the baseline values in 2001. There were significant moderate correlations between the values of 2001 and 2011. We concluded through that medical profession strain has a significant impact on increasing the CVDs risk factors, as all of blood pressure, blood glucose levels, cholesterol, weight and stress hormones showed significantly evident increase in the studied cohort in 2011 than 2001. Re-evaluation after 5 years will be confirming of the current results. We recommend stress-coping procedures to mitigate the adverse effects of medical profession strain while keeping observation of the CVD risk factors by regular medical check-ups.

Abstract: Background and aim: Human coronavirus NL63 (HCoV-NL63) is a recently discovered human corona virus that causes respiratory illness in children. In this study, we looked for HCoV-NL63 in children with acute upper respiratory tract infection by reverse transcription polymerase chain reaction (RT-PCR) and determined coinfections between HCoV-NL63 and other respiratory viruses. Subjects and methods: Nasal secretions collected from 160 children with acute upper respiratory tract infection and 80 controls were subjected to reverse transcription-PCR (RT-PCR) for detection of HCoV-NL63 virus and direct immunofluorescence (DIF) for detection of seven respiratory viruses (RSV, influenza A and B viruses, parainfluenza virus types 1 to 3, and adenovirus). Results: We detected HCoV-NL63 RT-PCR in 24 out of 160 (15%) nasal secretion specimens collected from children with acute upper respiratory tract infection. All children with HCoV-NL63 infection were aged from 12- 32 months. Direct immunofluorescence assay detected RSV, influenza A, influenza B, and adenovirus in 42(26.3%), 23 (14.4%), 15 (9.4%) and 4(2.5%) respectively in the nasal secretion specimens of the patients. RSV was detected positive in 10 (43.4%) children with HCoV-NL63 infection, influenza A was detected positive in 4 (17.4%) patients with HCoV-NL63 infection, 4 (17.4%) patients with RSV infection and 3 (13%) patients with influenza B infection. While RSV was detected positive in 2 (8.7%) adenovirus infection. Conclusion: HCoV-NL63 is frequently detected human pathogen, often associated with other respiratory viruses and acute respiratory tract infections in children. Rapid DIF screening reagent for detection of multiple respiratory viruses within 1 to 2 hours is of great benefit in terms of patient management and infection control.

Abstract: Background: Patients admitted to ICU unit are confronted to various organic, nervous, and metabolic changes that may affect the prognosis and outcome in them. The recognition of Acute Kidney Injury (AKI) by measuring serum creatinine level often occurs hours to days after the initial insult, hence the need for specific marker(s) that can detect renal injury in earlier stages for institution of appropriate therapeutic measures to reverse or prevent worsening of functional or structural kidney abnormalities. Aim of study: To determine the incidence, the etiology, clinical characteristics and prognosis of acute kidney injury in patients admitted to various intensive care units at Banha University Hospitals, and to evaluate different therapeutic modalities given to those patients for management of acute kidney injury. Methods: All patients who were admittedto intensive care units (ICUs) at Banha University Hospitals were prospectively studied. Patients who developed ICU-acquired acute renal failure were collected in the period between the first of November 2007and 31th March 2010. Results: In Our study 749 patients (21.2%) were met AKIN criteria, 26.3% classified as stage 1, 20.2% classified as stage 2, 53.5% classified as stage 3. There was an increase inhospital mortality with increasing AKIN class with patients who werestage 1having mortality rate of 30.5%, patients who were stage 2 having mortality rate of 50.3%, patients who were stage 3 having mortality rate of 52 %. In Our study 742 patients (21%) were met RIFLE criteria, 24% classified as Risk[R], 28.2% classified as Injury[I], 47.8% classified as Failure[F].There was an increase in hospital mortality with increasing RIFLE class with patients who were class R having mortality rate of 30.9%, patients who were class I having mortality rate of 49.3%, patients who were class F having mortality rate of 62 %. In Our study when comparing corresponding degrees of AKI according to AKIN and RIFLE (stage 1 versus ‘risk’; stage 2versus ‘injury’; stage 3 versus ‘failure’) no statistical difference in mortality. Conclusions: RIFLE criteria represent a simple tool for the detection and classification of AKI and for correlation with clinical outcomes. The AKIN criteria do not materially improve the sensitivity, robustness and predictive ability of the definition and classification of AKI.

Abstract: Dams are built to provide water for irrigated agriculture, domestic or industrial use, to generate hydropower or help control floods. Decisions to build dams are made, as human knowledge and experiences expand and new technologies develop, parallel with the fact that the decision-making process is also increasingly becoming more open, inclusive and transparent. Despite the benefits provided by the dams to humankind, much environmental damage has occurred as a consequence of these projects. In particular, dam projects often lead to considerable changes in the natural ecosystem. As the changes are related to the fundamental ecological issues, ecological input should be mandatory and play a major role in all dam project decisions. This paper looks into various studies on the application of ecological evaluation methods in regards to the EIA for the land-use development projects, particularly the dam projects. It details the limitation and challenges faced by the ecological evaluation. Alternative approaches are considered and elucidated as the way forward to enhance the ecological evaluation framework. Towards this end, an ecological evaluation method for the EIA of dams based on ecosystem rarity is proposed. This method allows the loss and fragmentation of the ecosystem of the alternative dam site to be determined in an objective and replicable way.

Abstract: PPP is an alternative procumbent method being adopted public infrastructure development worldwide. In PPP method, public sector invites private agencies to bring their capital and technical assets for executing public projects. PPP is being popularized worldwide for its potential benefits. However, a number of projects with PPP process are failed in achieving the target in many countries. In Malaysia also, nowadays, Public-private partnership (PPP) has been widely used in large scale infrastructure projects. PPP is considered as derivative of privatization concept initiated since in Malaysian context. The success and failure of PPP project depend on the performance of both public and private sector. Thus, in order to achieve successful projects, it is very imperative that the role and performance of the two sectors be clearly identified and studies. Further, for achieving successful PPP projects, it is also very essential to learn the lesson from the past fail projects. Hence, this paper is a case study of LRT project of Malaysia to understand the reason of failure. Study highlighted that Kuala Lumpur LRT project was failed during the operation phase. Key reason of the failure was the financial crisis of 1997 where inflation rate increased from 8% to over 40%. This financial crisis resulted to the less profit rate, and the concessionaires were not able to repay the loan to the banks which they had taken for LRT construction works. Finally, through undergoing a legal process in 2002, Syarikat Prasana Negara Berhad took over PUTRA-LRT and STAR-LRT on the behalf of the government of Malaysia.

Abstract: Construction projects are often facing a severe problem of variations. The variations of caused by numerous factors. These variations have significant effect of the project performance especially the quality of the works. This paper has investigated the probability of occurrence of various factors of variations and the relative responsible party causing this occurrence of factors. Also, level of significance for each factor in affecting the quality of the projects is assessed. Data collection for this study involved survey using questionnaire with client, consultant and contractors. Statistical analysis of all 101 completed questionnaire received against 200 distributed forms was carried out with SPSS software package and average index method. Finding of the study highlighted that the top 5 factors which are most commonly occurred in construction projects are unavailability of equipments, poor workmanship, design complexity, change of schedule and impediment to prompt decision making process are the. Consultants are found the responsible for most of the projects i.e. 12 factors out of 18 investigated factors. Poor workmanship, changes in specification, financial difficulties, inadequate working drawing details and change in design are rated as the top 5 significant factors in affecting quality of the projects. It is recommended that changes in specification and design be minimized; effective financial management be adopted to reduce variations and improve the quality of the projects.

Abstract: One of the vital components in dam design is the dam outlet structure (the principle spillway). The current practice in the design of dams in arid zones is mainly based on design manuals developed by the US corps of engineers which apply to rivers and channels that have a continuous flow. These methods do not suit the conditions of arid zones where there is an intermittent flow due to intermittent rainfall events. A methodology has been developed in this paper for the design of dam outlets in arid zones. The methodology considers common features of the arid environment such as intermittent rainfall events, temporal variability of flow in the dam reservoir, and the shape of dam reservoir. A spreadsheet model has been developed to program the governing equations and implement the methodology. The theoretical back ground of the methodology is presented and applied on a proposed dam case study in Saudi Arabia. The corresponding performance curves of the dam outlet have been established.

Abstract: In the current times, Information Systems (IS) are becoming major part and parcel of every growing institution. As a result of the highly number of users and ever growing volumes of data, there is an ever growing need to incorporate reliable systems to provide the required services by the institution in terms of data acquisition warehousing and security. In King Abdulaziz university (KAU), the Academic Information System (AIS) plays an important role as it foster a data management environment that is robust and can be expanded according to an organizations' strategic plan for information processing. So, the AIS are seen to be a powerful tool in the present scenario of online academic services. These services are provided by many leading universities all over the globe and feature many utilities and approaches. This article will critically analyse various AIS in the leading institutions of Saudi Arabia with reference to KAU AIS. Also, this article search for investigating the justification for AIS benefits. The case study strategy was used because it is more practical for business and management research; where.it engages in the empirical investigation of a specific phenomenon in a real-life environment, in addition to multi-source methods of data collection. This strategy helps achieve a greater understanding of the research context and process and answers ‘why’, ‘what’, and ‘how’ questions due to its capability of using multiple methods, including interviews, documents, and observation, to collect data. Finally, it was concluded that the existing AIS supports the real-time multi-processing environment within KAU through using the concept of time-sharing application where Time-sharing application allows for the prioritizing of applications based on user-id and system priority assigned to an application, device, and database or system catalog. These features are important to the university because it process transactions while developing and testing program applications. In a multi-processing environment, various faculties, departments or deanships can have access to the system at the same time intervals.

Abstract: About 3-10% of breast cancer patients have distant metastases at initial presentation. Patients with metastatic breast cancer have limited therapeutic options, and the mainstay of treatment remains systemic chemotherapy. Traditionally, the role of surgery has been confined strictly to palliation. However, retrospective studies have shown improved survival in patients who underwent surgery for their primary tumor. Thus, new clinical questions have emerged regarding surgery of the primary site in those women with metastatic disease and a respectable intact primary tumor. This study included 151 patients with stage IV breast cancer who divided into two groups:  Group A, who underwent surgery   and Group B, who did not undergo surgery. All patients then received anthracyclin based chemotherapy followed by hormonal treatment according to hormonal status. Patients were evaluated after three cycles of chemotherapy, after 6 cycles of chemotherapy, and later on every three months. Patients characteristics and survival were evaluated using univariate and multivariable analysis. 151 patients included in this analysis, Group A: 61underwent surgery for their primary tumor and Group B: 90 patients did not. There is statistically significant difference as regard the results of the first evaluation between the two groups where 3patients achieved CR (complete response), 38 patients had stable disease and16 patients achieved partial response (PR) and 3 patients in disease progression (DP) in Group A while in Group B no patient achieved CR, 66 patients achieved PR, 12 patients had stable disease and 12 patients had DP. There was statistically significant difference as regard OS between the 2 groups, the mean survival for Group A was 39.10 months and 28.04 months for Group B. Primary tumor resection increased survival in patient with metastatic breast cancer. So the role of surgery in women with stage IV breast cancer needs to be re-evaluated.

Abstract: The present study has demonstrated that the immunocompromised patients in National Cancer Institute (NCI) (Cairo, Egypt) are infected with several microorganisms due to their immunodificiency as a result of chemotherapy. The study included 435 of immunocompromised patients in NCI. The mean age of patients with infections was 42.5 ± 14.7 years (range, 20 to 72) in adult, and pediatric 4.1±3.2 years (range, 0.5 to 13). The nosocomial infections occurred in 173 patients, these patients infected with Gram positive, Gram negative bacteria and Candida albicanes. Gram positive bacteria constituted the majority of isolates 70.9% compared with Gram negative bacteria 29.1%.The most effective antibiotics against Gram positive bacteria were found to be Vancomycin Linozolid and Synercid (71.5%), (63.1%) respectively, In case of Gram negative bacteria, the most effective antibiotics were Tobramycin and Amikacin with percentage (88 %) and (68%), respectively. The infection with pseudomonas spp. in immunocompromised patients occurred 5.8% and we observed that the percentage of infection among females was higher than in males with significant association (P= 0.02). The most effective antimicrobial agents against Pseudomonas spp. were Impienem, Meropenam 70%, Tobramycin and levofloxacin 60%.

Abstract: This is a data exploratory analysis of retrospective cross-sectional study of pattern of first birth interval after marriage in Nigeria. The data for the study are extracted from the published reports of the National Demographic and Health Survey 2009 edition. Fertility as a major component of population change is influenced by first birth interval after marriage, since the interval is positively correlated with the cumulative number of children a woman would have at the end of her reproductive life. Studies have described this interval using non-parametric methods which lack features to project the estimates further. This paper is designed to fill the gap by attempting to fit a parametric model to data on the first birth interval among women of reproductive age in Nigeria. Four parametric models whose various curves and estimates are compared with non-parametric values are considered, namely Inverse Gaussian, Log-logistic, Weibull and Burr Type XII. The best model appears to be Inverse Gaussian based on the Akaike Information Criterion of lowest value of 116617.6. Quantile-quantile plots also identify Inverse Gaussian as model whose data points clustered much around straight line. All other curves give credence to the Inverse Gaussian model as the one that describes the data better than the rest. However, the study does not rule out adaptability of Log-logistic distribution to model waiting time to first birth after marriage since it also behaves similarly to Inverse Gaussian distribution.

Abstract: The development of an infrastructure requires a planned and effective construction management including the construction of the university. To obtain a good ranking, the universities should provide comprehensive physical facilities and infrastructure. This study is to investigate the construction process to know the causes behind the delay process in constructing the high education facilities in the Malaysian universities. The Rasch model technique is applied to analyse the results, and the sample of this study included 100 respondents where the majority are managers and owners of the construction of the high learning institutions. The delay causes are grouped into three factors, there are input factor, internal factor and exogenous factor. It is revealed that internal factors were the most factors that contribute in delay construction process, the factors as follows: poor monitoring by the contractor, lack of consultants experience, changes in design, too many variation orders by owner, delay in making decisions by project owner.

Abstract: The relationship between the L-Arg-NO pathway and tumor growth has not yet been clearly elucidated. The aim of this study was to explore the effects of L-arginine (L-Arg) on cell proliferation, inducible nitric oxide synthase (iNOS) expression and the cell cycle in the human colon carcinoma cell line LS174. LS174 cells were cultured with L-Arg at different concentrations for different times. The MTT method was employed to evaluate the level of cell proliferation. The production of nitric oxide (NO) in the culture supernatants was detected by the enzymatic reduction of nitrate. The distribution of the cell cycle was detected using flow cytometry (FCM). The expression levels of iNOS were determined by western blot and immunohistochemical staining. The growth of LS174 cells was promoted by L-Arg at low concentrations (0.125 mmol/L) and inhibited at high concentrations (0.5, 2, 8, or 32 mmol/L). The levels of NO increased with increasing concentrations of L-Arg. Compared with the control group, the ratio of cells in S phase was increased after 48 hour’ treatments with high concentrations of L-Arg (0.5, 2, 8 or 32 mmol/L) (P<0.05P<0.01); but there was no obvious difference after treatments with a low concentration (0.125 mmol/L) (P>0.05). With the increase in L-Arg concentrations, the expression of iNOS increased. L-Arg can induce the expression of iNOS resulting in an increase the production of NO. Low concentrations of L-Arg can promote growth, whereas high concentrations can inhibit the growth and proliferation of LS174 cells. High concentrations of L-Arg can induce S phase arrest.

Abstract: Salinity is the most important stresses that reduce growth and yield of wheat plant. In order to study effect of salinity only as well as presence of antioxidants (β-carotene, glutathione, uric acid) individually or in combination of both on growth and some related physiological activities of wheat plant an experiment was conducted completely randomized design with three replications.. The decreased levels of seed germination and growth alterations induced by NaCl were alleviated by various levels of antioxidants. Application of antioxidants led to significant differences between responses of antioxidant defense system either non-enzymatic {glutathione and ascorbate} or enzymatic {catalase (CAT), ascorbate peroxidase (APX), Superoxide dismutase (SOD) and Glutathione reductase (GR)}. Protein profile of T. aestivum show variations in the number appearance, disappearance of bands, and variation in the protein content in each band compared to control and to the percentage of each band in the same sample and finally its molecular weight. When treated with NaCl or in combination with antioxidant the organic solutes of wheat seedlings exhibited somewhat variable responses to the salinity levels.

Abstract: The current study aimed to investigate the protective effect of hesperidin against hyperammonemia-induced inflammation and oxidative stress. Hyperammonemia was induced by daily intraperitoneal injection of 100 mg/kg body weight ammonium chloride for 8 weeks. Administration of ammonium chloride induced hyperammonemia as evident by the significant increase in blood ammonia and urea levels. In addition, hyperammonemic rats exhibitedsignificantly increased brain lipid peroxidation as well as declined glutathione content and glutathione peroxidase and superoxide dismutase activities. Moreover, hyperammonemia induced a significant increase in serum tumor necrosis factor alpha (TNF-α) accompanied with significant upregulation of brain TNF-α mRNA expression.  Concomitant administration of the flavonoid hesperidinsignificantlyameliorated the altered parameters. In conclusion, hesperidinprotects against hyperammonemia-induced oxidative stress and inflammation, demonstrating its antioxidant and anti-inflammatory efficacies.

Abstract: The 19-20th century period witnessed active migrations between populations in many countries. Internal migrations were determined by specific political, economic, social and cultural development of the states. Those were particularly active in multinational empires. Migration specificity in the Russian Empire was that they had both compulsory and voluntary nature. They directly affected the ethnic composition of regions. This article will focus on the correlation between voluntary and compulsory migrations in the formation process of specific ethnic groups, and analyze their influence on changes in the national composition of people living in a certain region.

Abstract: Background: The incidence of diabetes is increasing rapidly with interference in electrolytes sodium (Na+), potassium (K+) and chloride (Cl-). The aim of the study is to estimate the electrolytes disturbance in Diabetes patients.Material and Methods: Total of 188 subjects were included in the study, out of which two groups were formed; 94 type 2diabetes patients and 94 controls. The subjects were selected from the outpatient department of King Abdul Aziz University Hospital, Riyadh. Biochemical analysis for fasting glucose, HbA1C, Na+, K+, Cl- was performed by the ROCHE module Cobas 6000 (C-501 and C-601) analyzer, and kits were procured by ROCHE. Student t test was done to find out the difference between the two paired groups at 0.05 level of significance, followed by Pearson's correlation to know the correlation between electrolytes and glycemic control parameters, and the correlation coefficient (r) values were represented at 0.05 & 0.10 level of significance. Results: Diabetes patients Were of mean age 51.6 ± 14.7 years. In diabetes group serum Na+ level was observed significantly decreased (129.3±5.1) while Cl-mean was increased (116±5.5), K+ showed no significant alterations. Both the electrolytes (Na+, Cl-) differ significantly in diabetes and control group, at 0.05 level of significance. In both the sexes Na+ & Cl- were significantly associated with fasting glucose and HbA1C, respectively. Discussion: The study demonstrated significant association of Na+, Cl- with type 2 diabetes patients and K+ insignificant with diabetes control.

Abstract: Acrylamide is a probable human carcinogen that is present in several heat-treated foods such as French fries, potato crisps and coffee. We conducted the present study to investigate the protective effects of onion peel powder (OPP), rich in phenolic compounds, on the acrylamide (AA)-induced cytotoxicity and immunotoxicity in liver cell cultures. Cytotoxicity (lysosomal dysnfuntion assayed by NR, mitochondrial dysnfunction assayed by MTT and cell wall membrane integrity assayed by CV) and immunotoxicity (assayed by PA) effects of acrylamide in liver cells cultures were observed. The midpoint toxicity values of AA treated samples were 8.00, 9.80, 9.75 and 17.00 mg/l for NR, MTT, CV and PA assays, respectively. Treatment of AA samples with OPP, 2.5 mg/l, increased these values (decreasing the cytotoxic and immunotoxic effects) and recorded 11.00, 9.50, 14.75 and 19.75 mg/l, respectively. The rate of decreasing in different assays are directly proportional with the increasing of the OPP concentration until removed totally at 20 mg/l. PEG-SOD (a superoxide scavenger) and PEG catalase (a hydrogen peroxide scavenger) examination indicated that ROS is involved in AA-induced cytotoxicity and immunotoxicity in liver cells. These data suggest that agricultural by-products rich in phenolic compounds such OPP could attenuate the cytotoxicity and immunotoxicity induced by AA in liver cells. The protection is probably mediated by an antioxidant protective mechanism. Using of OPP as a natural food additives in both deep-fat frying process and heated-treated foods may be a worthwhile way to prevent AA-mediated cytotoxicity and immunotoxicity.

Abstract: Pharmacological preconditioning limits myocardial infarct size after ischemia/reperfusion. Dexmedetomidine is an α2-adrenergic receptor agonist used in anesthesia that may have cardioprotective properties against ischemia/reperfusion injury.We investigate whether dexmedetomidine administration activates cardiac survival kinases and induces cardioprotection against injury. Grave scalding rat model was established.Blood presure and heart rate were atraumatic measure, the blood and the myocardial tissue from ventriculus sinister were harvested, which were assayed the troponin, myocardial apoptosis, and the expression of caspase-12,GRP78 and CHOP by immunohistochemistry, terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling(TUNEL) and western blotting. we found that the number of buffy-stained nucleolus in the myocardial cell was the most in the simple scald group. The number of buffy-stained nucleolus of myocardial cells in the D1 and D3 group were more than that in the D2 group, which were more than in the normal control group. The proteinic expression of GRP78 and CHOP in the D2 and D3 groups were less than that in the B group. The proteinic expression of GRP78 in the D2 group was less than that in the D3 group.The proteinic expression of CHOP in the D2 and D3 groups were more than in the normal control. dexmedetomidine could lessen the myocardial cellular apoptosis induced by scald, inhibit the expression of caspase-12, GRP78 and CHOP.

Abstract: In this paper, a new pattern matching algorithm is proposed. The new algorithm Enhanced Berry Ravindran (EBR) algorithm made enhancements on Berry-Ravindran (BR) algorithm. In BR, the shift value is computed by taking two consecutive characters of the text immediately following the pattern window. The new algorithm maximizes the shift used in BR by computing the shift value using three consecutive characters. EBR uses two sliding windows to scan the text from the left and right simultaneously. In each sliding window the comparisons made between the text and the pattern are made from both sides of the pattern at the same time. The proposed algorithm shows better performance compared with the existing algorithms in terms of number of comparisons and attempts.

Abstract: Boron is an essential micronutrient for normal growth of higher plants, when it absorbed in excess amounts, it can be toxic and induce a number of deleterious effects. Tomato is one of the crops which respond well to boron application. A germination and pot experiments were conducted in order to assess the possible effects of boron (0.0, 100, 200, 300 and 400 ppm) on the growth and some metabolic activities of tomato at 9 and 30 days of growth. Application of different concentrations of boron significantly increased fresh and dry weights at low boron concentrations (100 and 200 ppm) compared with control. In addition, the content of Ca and B were increased in shoot and root of tomato, K was increased in shoot and decreased in root, while Na increased in root and decreased in shoot in response to boron application. The activity of glutamate-oxoloacetate and glutamate-pyruvate transaminases enzymes was significantly increased with the applied boron concentrations. Moreover, the root and shoot soluble proteins were increased gradually with increasing boron concentrations. The protein profile of tomato seedlings revealed de novo synthesis of polypeptides with molecular weights 116, 97, 35, 33 and 11 KDa with the highest boron concentration (400 ppm) which may be associated with the tolerance of tomato to excess boron.

Abstract: This article focuses on the processes of ethnic and cultural identification and self-identification, which the indigenous peoples of the North of Russia and Siberia, living in the Russian Federation, are currently going through. The post-Soviet cultural practices of preservation of ethnic identity of the small-numbered peoples of Siberia—the Kumandins and the Dolgans —are studied. The conclusion is made that there is not any state language policy aimed at preserving of the Kumandin language and Dolgan language. The Kumandins and the Dolgans have active processes of ethnic identification, but the post-Soviet cultural practices do not relate to these processes. Processes of ethnic and linguistic assimilation are accompanied by post-Soviet practices, where state policy does not increase and does not weaken the ethnic identity of the indigenous peoples of Central Siberia. In present time are developed and strengthened social stratum “national elites”, which are characterized by symbolic ethnicity. For modern ethnicity processes of Indigenous Peoples of Central Siberia are characterized by dual ethnic identity.

AbstractClinical efficacy of immunotherapy using dendritic cells (DC) and cytokine induced killer cells (CIK), combined with chemotherapy was observed in lung cancer patients. Thirty five patients with lung cancer, who admitted to the Second Affiliated Hospital of Zhengzhou University from August 2012 to June 2013 were treated with the regimen of DC-CIK based immunotherapy combined with chemotherapy. Healthy control (n = 6) were age-and sex-matched. The ratio of CD4+CD25+ FoxP3+ (Treg), CD8+CD28−(Ts) and CD8+CD28+(CTL) were analyzed using flow cytometry. Patients received 4~107 DCs and 5~10×109 CIKs in total during the treatment courses. There was an increasing tendency for proportions of T subsets and NK cells, and decreased tendency for tumour markers in peripheral blood after treatment though no statistical significance. CR was found in 3 cases (8.6%), PR in 8 cases (22.9%), SD in 21 cases (60%) and PD in 3 cases (8.5%) within 1 year follow-up. Patients showed significantly higher percentage of Treg and lower level CTL in peripheral blood compared to healthy control (P<0.05), and recovered to similar level as healthy people. No serious adverse reaction was found in all patients. We can conclude that DC-CIK cellular immunotherapy combined with chemotherapy is beneficial for lung cancer in improving quality of life, and reducing levels of Treg in peripheral blood without serious side effect.

Abstract: Kazakhstan is one of leading producers of rice in the CIS where holds a peculiar place Kyzylorda province, in particular the lower reaches of the Syr-Darya River with favorable natural conditions and and the specialized engineering prepared lands. Increase of efficiency of agrarian industry and domestic markets is the major problem. In the paper there are the results of long-term researches on increase of rice production on the meliorated saline soils in Kazakhstan. It is established during the research, that the farther rice is located from a bed of long-term grasses in a crop rotation, the more there is a difference in productivity under the influence of salts in soil. With increase of level of soil salinity on rice crops the efficiency of mineral fertilizers fell by 20 %. It considerably occurs when proportionally increased in doses of mineral fertilizers (N60-150, Р90-120, K45-90) depending on level growth of soil salinity on rice crops.

Abstract. Formation and accumulation of experience in cultural activity forms the thinking and culture in its entirety. The experience of intercultural activity is one of the attributes of the modern culture, in which harmonious development depends on the interaction of different cultures. Education meeting social, political, and economical requirements of the contemporary society is meant to solve the problem of intercultural education. Formation of democratic and tolerant intercultural personality, which retains its own culture, but understands and accepts other cultures and has sufficient competence for adequate behavior in the circumstances of cross-cultural communication, is the finite goal of intercultural education. This all is achieved through application of certain communicative strategies, which are assumed the strategies of mutual understanding, cooperation, competition, and avoidance of conflicts. The progress of the modern society is impossible without formation and accumulation of this experience, which is understood as sociocultural, sociolinguistic, and intercultural competences. These competences are necessary for successful integration into the world cultural space, which is characterized as orientation to the communication partner.

Abstract: The main aim of this study is to investigate the environmental challenges – changing climate and natural disasters affect on aquaculture activities in Malaysia. Four in depth interviews have been conducted with five brackish-water cage entrepreneurs from four different locations in Peninsular Malaysia. Based on the findings of this study, four main environmental challenges have been identified to post formidable challenges on aquaculture activities in Malaysia, namely temperature rise, heavy rainfall, flood and water current. Further analyses have shown that these four environmental challenges have affected the socio-economic routines of the brackish-water cage entrepreneurs. A number of discussions and recommendations have been highlighted and hopefully they can assist the relevant parties in constructing a better strategy to face the future environmental challenges.

Abstract: Gait analysis is a complex process since it involves tracking motion with high degrees of freedom. It has seen a lot of development in recent years with approaches changing from Markerbased to Markerless systems. This paper presents a new approach for gait analysis that is based on Markerless human motion capture using Microsoft’s popular gaming console Kinect XBOX. For this study, the RGB camera mode output of the Kinect system was used as Markerbased system. The skeleton mode output of the Kinect system was used as Markerless system. The system introduced in this paper tracked the human motion in a real time environment using foreground segmentation and computer vision algorithms developed for this purpose. The study shows that Kinect can be used both as Markerbased and Markerless systems for tracking human motion. The degree angles formed from the motion of 5 joints namely shoulder, elbow, hip, knee and ankle were calculated. The RGB camera of Kinect was used to track marks placed over specified joints. The image resulting from the Kinect skeleton mode was considered as the images resulting from markerless system and used to calculate the angle for the same joints. The developed software application tracked the motion successfully. The study showed a correlation coefficient of 90.16% between the Kinect camera’s Markerbased and Markerless systems.

Abstract: Objective By observing the clinical efficacy and drug side effects of lipid-lowering treatment of ezetimibe combined with atorvastatin calcium, we evaluated the value of ezetimibe in postoperative patients’ blood lipids management after interventional therapy of acute coronary syndrome. Method 160 abnormal plasma lipid patients with acute coronary syndrome who accepted coronary artery interventional therapy in our hospital, were randomly divided into two groups——the control group taking atorvastatin calcium tablets, the experimental group taking ezetimibe and atorvastatin calcium tablets, we compared the changes and side effects of low-density lipoprotein cholesterol (LDL-C) and total cholesterol (TC) after treatment for a month between the two groups. Result After 30 days, TC, TG (Trigly cerides) and LDL-C in plasma of the experimental group are lower than the other group (p<0.01). Conclusion The clinical effect of ezetimibe combined with atorvastatin calcium tablets in treating hyperlipemia was obviously superior to taking atorvastatin calcium tablets alone, such as making the blood fat standardized earlier and without increasing side effects, which was particularly suitable for substandard plasma lipid patients after interventional treatment of acute coronary syndrome.

While Sender-receiver type has been used traditionally, RBS (Reference Broadcast Synchronization), the representative of Receiver-receiver approach, was developed to provide higher synchronization accuracy by removing the sender’s non-deterministic delay for the critical path, which approach has been referenced by so many other WSN synchronization schemes till now. However, RBS has limitations that it consumes too much energy to exchange large amount of messages and does not support an absolute global clock efficiently over an entire network. In this paper, we propose a new synchronization scheme to provide an absolute global clock for a network, which has RBS-like approach and less message exchange so as to reduce power consumption.

Abstract: Since the test results may differ according to the motion orders of a thread even in the same situation, it is very difficult to develop multithread software. To address this problem, a software development method using a concurrency control approach based on a discrete event simulation is proposed here. Concurrency control refers to the pursuit of a management method to maximize the concurrent execution when it is necessary to handle many tasks underway at the same time, while maintaining the capabilities of the system. However, it would not be cost effective if, when testing the functions of software, changes are made to the thread’s concurrency by revising the software directly. This study shows the feasibility of effective concurrency control through the use of simulation. The proposed method, which is demonstrated with the development of navigation software, explains the process of software development.

Abstract: With the development of information technologies, computers play an important role in education and have been widely used for after-school activities. The students are also able to use computer-aided learning content anytime and anywhere due to the development of computer network technologies. Recently, there are efforts in using robots as one of devices to assist learning activities. The r-learning system was developed for aiding students’ learning activities in this research. In order to improve the contents and responses of the r-learning system, it is necessary to conduct research to find the important factors that affect the intention to use the system. This paper shows the results of a preceding study to find important factors. The analysis result on the basis of the Technology Acceptance Model (TAM) suggests that the information technology level of users is a significantly important factor on the intention to use the r-learning system. This research is a preceding study and further analysis with other variables will be conducted in order to find the significant factors affecting the intention to use r-learning users.

Abstract: Recently, NAND flash memory is widely used as storage media in various devices such as SD card, USB memory, and solid state drives (SSDs). NAND flash memory has different characteristics from hard disks, and thereby a firmware called flash translation layer (FTL) should be deployed to use traditional file systems on NAND flash memory. Because FTL majorly determines performance and stability of NAND-based block devices, various FTL schemes have been developed. However, their efficiency has been evaluated via simulation not on a real device, which restricts the reliability of the results. Recently, OpenSSD platform, which allows implementing a new FTL scheme on real NAND devices, was developed. By using it, evaluating the FTL performance on real NAND devices becomes possible. The problem is that it is difficult and time consuming to debug the new FTL on the OpenSSD platform. In order to address this, we design an OpenSSD simulator that helps find the bugs of FTL and reduces the test time. The FTL developed on the simulator can be migrated to the OpenSSD platform without additional porting.

Abstract: Current digital door locks have a risk of being broken because they are exposed outside and damaged by the electric shock. In order to increase safety, this work proposes an unexposed door lock, which removes the keypad in the outside. Instead of the keypad, it recognizes knock pattern. Users can setup the password using the knock pattern, and by knocking the same pattern, the door is open. The door lock can communicate with the smart phone application, also. Users can open the door by inputting the knock pattern to the smart phone, and it further increases safety because it removes the knocking sound and the possibility of being overheard.

Abstract: The purpose of this study was to investigate how the threshold condition used in a bone density scan influences the morphological parameters and to find an optimal threshold for predicting osteoporosis. Experimental subjects comprised a total of 54 post menopausal women aged over 40 years, who were classified into two groups, 20 normal and 34 osteoporosis patients, according to their T-scores. Bone mineral density was measured on the femoral neck, greater trochanter, and Ward’s triangle by dual-energy X-ray absorptiometry. To set the threshold conditions, we employed a newly proposed thresholding method using thresholds ranging from 0 to 95% based on the trabecular bone area. We also selected seven evaluation parameters that composed of structural parameters, skeletonized parameters, and fractal dimension to evaluate the osteoporosis predictability. Based on the experimental results, we found that a threshold condition of 20% yields the most reliable predictability for osteoporosis. Quantitative evaluation also demonstrated that the statistical significances are weakened, as the threshold excessively increases.

Abstract: Iron deficiency, which is used to diagnose anemia, is often identified by the measurement of hematocrit levels, and hematocrit levels have been associated with specific morphological features. However, no studies have evaluated the best indicator for identifying hematocrit levels derived from morphological features using machine learning. The objectives of the present study were to identify the best indicator of hematocrit levels among several morphological features and to predict hematocrit levels using a combination of morphological features based on data mining techniques. A total of 1,838 subjects participated in this study. We used two machine learning algorithms, logistic regression (LR) and naive Bayes (NB) algorithms, to identify the best indicator among several morphological features. To overcome the class imbalanced problem and select important features, the synthetic minority over-sampling technique and wrapper-based variable selection were applied to the data set in prediction experiments using combined features. Among all individual features, the best indicator for predicting high and low hematocrit levels was age (p = <0.0001; OR = 0.352; AUC = 0.756 by naive Bayes and 0.759 by logistic regression), and among all morphological features, the strongest predictor was body weight (p = <0.0001; OR = 1.724; AUC = 0.639 by naive Bayes and 0.641 by logistic regression). For the combined features examined, the area under the receiver operating characteristic curve (AUC) of the four models ranged from 0.745 to 0.789. The method using NB algorithm with wrapper-based variable selection showed the best predictive accuracy (AUC = 0.789; MCC = 0.445) and proved suitable for the prediction of low and high hematocrit levels; this method decreased the model complexity, resulting in the best prediction accuracy and providing the most cost-effective approach. The findings of the present study provide medical knowledge for primary screening and support the use of tools to predict hematocrit levels in both on-site and remote-site healthcare services.

Abstract: An intelligent transportation system (ITS) is an application that provides dynamic traffic information to users so that the users can make safer and smarter use of transport networks. Examples of information type provided by an ITS include: bus arrival information, route information, bus service information, allocation information, route arrival information, station arrival information, front and rear car interval, transit time, and so on. In order to identify vehicles and detect locations and speeds of vehicles, we have to install a lot of special equipments in an ITS. For example, road side equipments (RSE), automatic vehicle identification (AVI) systems, automatic vehicle locations (AVL) systems, trunked radio systems (TRS) are needed to be installed in an ITS. Consequently, the cost to implement and maintain an ITS is enormous. This paper introduces a design of an Android App system that provides bus location information. The structure of our system contains three components: service request client, location up-loader,  and a server. Design detail of the system is discussed in this paper.

Abstract: Due to the advances of mobile devices with GPS (Global Positioning System), a user’ privacy threat is increased in location based services (LBSs). So, in LBSs, it is important to process given queries efficiently while protecting users’ privacy with a low bandwidth usage. For this, a 2PASS was proposed to search k-nearest POIs by generating cloaking regions which can hide the actual user location and reduce the bandwidth consumption. However, this method suffers from privacy attack. Therefore, we, in this paper, propose a privacy-protected k-NN query processing algorithm based on Weighted Adjacency Graph for Location-based services. Our privacy-protected k-NN query processing algorithm can reduce bandwidth usages and efficiently support k-nearest neighbor queries without revealing the private information of the query issuer. With performance evaluation, we show that our scheme outperforms the existing one.

Abstract: Features are measurable properties and used to classify patterns. When a feature set is large, we have to select a small feature subset, since the large feature set needs much computation time and has the problem of curse-of-dimensionality: when the dimensionality of feature set increases, the required sample size grows exponentially to train a classifier. Feature selection consists of two main procedures: subset generation and evaluation. The number of subsets grows exponentially when the number of set members increases. So, usual heuristic search methods are applied to generate subsets. Evaluation criteria to select a feature subset have been related to the training data. Such characteristics include relevance and redundancy with classes. But classifying new unseen patterns accurately is more important than classifying the trained data, which is called generalization capability. An improved feature selection method is proposed to improve the generalization capability. It uses wrapper-based feature selection and uses support vector machine as the wrapper. The experimental results show that the proposed method can reduce feature size and can improve the generalization capability.

Abstract: Real-time pricing (RTP) enables to give consumers information about the actual cost of electricity at any given time, and electricity prices change from hour to hour. However, in order to cope well with RTP, a real-time home energy management system (HEMS) is required. Therefore, in this paper, we introduce an efficient HEMS architecture, and propose real-time home energy management and on-demand home power control. In addition, to reduce wireless standby power by idle listening, we also propose adaptive power listening (APL), which is capable of dynamically adapting listening interval according to varying electricity load. We also developed real-time HEMS test-bed. Through experiments, it is demonstrated that proposed HEMS with APL can guarantee high real time response ability despite standby power reduction.

Abstract: SDN(Software-Defined Networking) is a next-generation networking technology that enables network path setting and control by software programming and entails efficient operation and management by separating the control plane and data plane. Recently, SDN has actively been deployed to virtualize networks for efficient network control and management in cloud environments, which have the characteristics of dynamic IT resource reallocation. This paper studies SDN-based security and analyzes its implication for SDN-based cloud environments. To overcome its limitation in a virtualized environment for a cloud datacenter, we propose a cooperation model between SDN-based and virtualization security to secure both of physical and virtual networks.

Abstract: Chronic disease is linked to patient’s’ lifestyle. Therefore, doctor has to monitor his/her patient over time. This may involve reviewing many reports, finding any changes, and modifying several treatments. One solution to optimize the burden is using a visualizing tool over time such as a timeline-based visualization tool. However, there was limitation of studying the diabetes patient’s history to find out what was the cause of the current development in patient’s condition. In this paper, we propose a workflow system based on the Grid-based Interactive Diabetes System (GIDS) to support bioinformatics analysis application for diabetes diseases. GIDS used an agglomerative clustering algorithm as clustering correlation algorithm.

Abstract: Recognition of vehicle license plates is applied in various fields, such as traffic control, unmanned tollgate and parking lot operation, and illegal vehicle control. For the unmanned management of vehicles, various license plate sizes should be accommodated. However, conventional studies have limitations in managing the variability of the license plate area.   In this paper, a method for extracting the vehicle license plate area for small to large license plates is proposed. A single image of a vehicle license plate is reduced and inputted in multiple steps using the pyramid technique, and then, the vehicle license plate areas extracted in stages are integrated in order to extract a candidate area of the vehicle license plate. When the license plate areas are integrated, they are first enlarged by applying reduction rates. A verification method for the candidate area is applied to the extracted candidate area in order to extract the final vehicle license plate area.   The test results indicate that the extraction process is performed effectively beyond the variability of license plate areas. The extraction rate of the vehicle license plate candidate text area is 100% and the extraction rate of the final license plate area through verification is 98%.

Abstract: A colored overlay has been used as an assistive device to reduce or eliminate visual stress. Recently, a kind of mobile colored overlays has been developed for people with visual stress; however, it can’t be applied to all contents of its environment. In this paper, We implemented a mobile overlay application based on the Android operating system and it can be applied to not only all contents in the system but also external contents such as book using camera mode. We applied it as a tool to Korean Wilkins Rate of Reading Test. All participants in the test have used a film overlay for one month more. The participants who used the film overlay for most reading tasks showed highly significant increases in reading speed (averaging 16.8%) with their mobile overlay. The mobile overlay helps to increase reading speed for people with visual stress.

Abstract: Semantic indexing of images is an ongoing study. Recently many researchers in the field of image classification for indexing of the very large image databases are interested in object(s) in an image. Thus, for efficient image matching use the semantic gap between higher concept of users and low-level image features. In this paper, we present a modified semantic classification method of the object(s) into natural/artificial classes, which can be of great interest for semantic indexing applications processing very large image databases. We first show that the modified segmentation method of the color images with irregular textures based on the block homogeneity. These works based on small-size blocks the color histogram of each of which is computed preliminarily once. Thus it works fast but provides rough segmentation. And using the segmented image, we show that dominant orientation features in modified Gabor orientation energy map of artificial objects are very useful for discriminating them from natural objects. Such Gabor energy maps for artificial objects tend to have dominant orientation features through analysis of Gabor filtering results for many object images. Then a modified sum of sector power differences is proposed as a classification measure, which shows a classification accuracy of 90.7% in a test with 3,000 object images.

Abstract: According to the rapid increase of data, the needs of intelligent data analysis and classification are also increasing. Though there have been developed various methods of classifying given data set into several pre-defined patterns, the distance-based classifier such as nearest neighbor classifier is still one of the most popular methods due to its simplicity and adaptability. However, in order to obtain good performances in practical applications, it is important to choose an appropriate distance measure considering the purpose of task and the distributional properties of data set. In this paper, we propose a new measure of similarity based on two probability densities: the class-conditional probability and the probability of within-class variation. Through statistical estimation of the probability densities using training set, it is possible to obtain an optimized measure for the given data. The efficiency of the proposed measure is confirmed by computational experiments on a few pattern recognition problems using benchmark data sets.

Abstract: The aim of the present study was to monitor the residues of 42 pesticides in different vegetable samples (tomato, squash, cucumber, egg-plant, green pepper, and potato) collected from 5 major supermarkets located in Jeddah, Saudi Arabia. A multi residue method was carried out by gas chromatography with mass spectrometry (GC-MS). Residues of some organophosphorus insecticides such as malathion and profenofos, as well as some pyrethroid pesticides, such as fenpropathrin and cypermethrin, were found in a number of samples at concentration levels exceeding or equal to their Maximum Residues Levels (MRLs). Data obtained was then used for estimating the potential health risks associated with the exposures to these pesticides. The Estimated Daily Intake (EDI) has been estimated between 0.00015 and 0.20 mg/kg body weight/day and the hazard index (EDI/ADI) less than the unity for the tested compounds.

Abstract: We applied simulated annealing and genetic algorithm to nurse scheduling problem. For time complexity problem of these algorithms, we suggested efficient operators using a matrix called a cost bit matrix. Each cell in the matrix indicates any violation of constraints. A cell with 1 indicates that the corresponding assignment violates any of constraints and needs further consideration. The experimental results showed that both algorithms with the suggested operators generated a nurse scheduling faster in time and better in quality compared to those without the matrix. In addition, simulated annealing with the matrix performed better than the corresponding implementation of genetic algorithm.

Abstract: The number of charging stations is smaller than the number of electric vehicles (EV) now. Efficient scheduling algorithms for charging EVs are necessary in smart grid cities like Jeju Island in South Korea. Thus, there have been a lot of research works on charging scheduling methods so far. However, we have rarely found the system that can reserve chargers for EVs as well as manage the chargers for efficient charging. In this paper, we propose a preemption-based reservation algorithm for charging EVs. Especially, our algorithm considers the chargers at tourist spots in Jeju-do. In order to achieve our research objectives, we implemented an Android-based App for the tourists. With our App, the tourists can easily reserve the charging stations by recommending the better chargers in terms of the waiting time and the amount of charging. Finally, we evaluate the performance of the reservation allocation algorithm with execution time and the number of missing requests.

Abstract: Peer assessment can enhance students’ learning effect by comparing their learning outcome with their peers’ outcome and by benchmarking them. It also helps students to increase their responsibility and autonomy. However, the peer assessment has usually been adapted in e-learning environment because of the easy use on the Web. On the other hand, many Education Collages in Universities encourage students to give presentations as one of class activities because the students can have confidence and build up their practical experience by their presentations. The peer assessment is a good way to use in presentation-based learning. Due to the advent of smart learning environment, students can learn anywhere and anytime. It means that smart learning eliminates the distinctions between on-line and off-line classes by using smart technologies. However, some instructional methods still have difficulties in performing in face-to-face classrooms because there is no system that keeps the class activities happened in our classroom like e-learning systems. In this paper, we design and implement a prototype of the peer-assessment system for students and teachers that can assess the peers and the students respectively. In addition, the proposed system stores the assessment result in a database and feedback the result to the students and the teachers for smart learning.

Abstract: Extracting topic keywords from on-line text documents is highly significant in text mining applications. In our work, extracted keywords are represented as a hierarchical topic tree. For this, we basically use incremental clustering technique for incoming online documents. Moreover, we define a cluster-based measure similar to the tf-idf measure and a probabilistic inequality to determine subsumption relationships among keywords. In this paper, with Google news data, we empirically analyze our proposed method in terms of the threshold value of incremental clustering algorithm, the range of keyword extraction measure and the amount of text data and prove its superiority.

Abstract: The increasing use of wireless Internet and smartphone has accelerated the need of location based services. Smartphones, especially IPhone or Android, stimulate growth of location-based service and mobile web computing. There are increasing demands and requests for application developers to support both smart platforms, simultaneously. Thus, we develop platform independent smart application which is exchangably executable for those two platforms. Our application provides the usefulness during the self-registry of real estate. It supports and increases the degree of user experience and convenience in HTML5 applications. In this paper, we show the design and implementation of a application which is able to calculate the amount of capital gain tax.

Abstract: Main memory management is critical for enhancing the performance of web server systems that include biological information. For decreasing the transaction time of incoming requests from users, such systems create several processes for future requests, saving the time needed to create processes that handle incoming requests from users. However, inefficient process management can decrease the performance of web server systems, and web cache systems connecting through proxy servers create dynamic access patterns that make it difficult to predict how many requests are coming into a system. Furthermore, while persistent and pipeline schemes decrease transaction time of incoming requests by sending multiple requests at the same time, these schemes waste available memory space by requiring multiple processes in order to handle multiple connections. Too many active processes result in a reduction of the system’s overall performance. Therefore, we suggest an adaptive process management scheme through web log mining. In our scheme, the numbers of web processes are controlled through prediction of incoming requests. Our management of processes saves on available memory without decreasing transaction time. We also demonstrate the effectiveness of our scheme through application to real web workload.

Abstract: In virtual machine environments, latency-sensitive tasks are difficult to support in a timely manner, especially when many domains have boosted priorities. Our approach considers where multiple domains compete CPU resource with several I/O intensive domains. This results in increased latency for time-sensitive domains, because the credit scheduler is not aware of the urgency of tasks within different guest domains. In this paper, we present a low-latency scheduling mechanism that uses VCPU shaping. The key idea of this paper is to adapt VCPU characteristics into a scheduling policy by investigating and measuring the behavior of each domain. Our experiment results show that the proposed method effectively allocates CPU resources for low-latency tasks.

Abstract: In cloud storage system, file synchronization schemes are widely used for efficient use of storage system. It reduces network traffic and processing time extremely. However, there exist several weak point in handling file synchronization for multiple clients. In this paper, to tackle this problem, we propose a bidirectional file synchronization scheme to efficiently deal with file copying between the client and the server. Experimental result shows that the proposed scheme can reduce data traffic efficiently using bidirectional file synchronization.

Abstract: Batch experiments were conducted on organic removal from wastewater by a commercial and native microbial inocula. The interaction effects of organic loading and excess aeration on the removal process was investigated using factorial design experiment. Biochemical oxygen demand (BOD) removal was significantly affected by the interactions of microbial inocula with aeration; their interactions could collectively explain 67.3% of the results. The effect of native inoculum on BOD removal was more evident under low aerated conditions and high effective microorganisms (EM) inoculum Ammonia removal was significant under aerated conditions and low EM density, reaching to mean removal values of 78% after 5 hrs.  Compared to EM, the individual strains of the Actinomycetes consortium showed higher enzyme efficiency in degrading carbohydrate and lipid compounds, while less activity to degrade protein compounds. Although, both inocula achieved good and comparable suspended solid removal values, the native consortium showed better inhibition of faecal coliforms. It is suggested that combination of commercial and native inocula may enhance wastewater treatment where both groups cooperate via complementary metabolic pathway.

Abstract: Education and training are expected to change dramatically due to the combined impact of the Internet, database, and multimedia technologies. However, the distance learning is often impeded by the lack of effective tools and system to manage and retrieve the lecture contents effectively. This paper introduces a system that enables remote users to access specific parts of interest from a large lecture database by contents. The system includes several novel techniques to achieve the content-based lecture retrieval: (1) The XML(eXtensible Markup Language)-based semistructured model not only to represent lecture contents but also to exchange them on the Web; (2) The technique to build structural summaries, i.e., schemas, of XML lecture databases. The structural summaries are useful for browsing the database structure, formulating queries, building indexes, and enabling query optimization; (3) An index structure to speed up the search to find appropriate lecture contents.

Abstract: The geochemical and isotopic data were examined to identify the origins of salinization in the shallow groundwater aquifer of El Agamy area, northwestern coast of Egypt. The groundwater of the coastal aquifer showed paths of hydrochemical evolution, from Ca–HCO3 type to Na–Cl or Mg-Cl type. Different molar ratios revealed the impact of seawater on the hydrochemical composition of groundwater of the aquifer to a great extent. The sewage effluents are expected to be important sources for increasing fluoride contents in the study area. Piper diagram showed that Cl and SO4 are the dominant anions, whereas Na and Mg is the most dominant cation. Durov diagram plot revealed that the groundwater type has been evolved from Ca-HCO3 type recharge water through to give mixed water of Mg-Cl and Na-Cl water type. The isotopic signature of groundwater shows that the stable isotope values of groundwater fall near the local meteoric water line and lie in the midway between the Mahmoudia Canal and the Mediterranean Sea indicating that major part of this groundwater originated from leakage of municipal wastewater, from improperly constructed septic tanks and directly from injection wells, and mixing with seawater underneath.

Abstract: With the development of human innovation, quality and quantity of food production have been increased in agriculture, thanks to the vertical farm system. The Ubiquitous computing serves as a bone for such environmental improvement through the smart devices that are linked with Internet of Things (IoT). Considering the vast skyscraper cultivation with vast amounts of crop production, the storing, retrieving and updating of the information for the services is handled, to acquire precise agriculture benefits. For this data to be effectively used, it has to be transferred through multiple systems which results in energy loss and communication latency. In order to use the service in a decoupled way, we present RESTful Architecture style for an HTTP based service interface in the vertical farm system. We have also presented the integrated of REST API in both mobile and web application of the vertical farm monitoring system. Jersey is used for web services to simplify the RESTful service and client implementation.

Abstract: In this paper we consider the problem of estimating the stress-strength reliability  when the available data is in the form of lower record values. The two-parameter exponentiated Weibull (EW) is considered, where both X and Y are independent and (EW) random variables with one different shape parameter, but having a common second shape parameter. The maximum likelihood estimator (MLE) and percentile bootstrap confidence intervals of R are provided. Also, we will apply Markov chian Monte Carlo (MCMC) techniques to study the Bayesian estimation of R and by Lindley's approximation technique as well. Assuming known common shape parameter, the MLE of R is obtained. The exact distributions of the MLEs of the unknown parameters are used to construct the exact confidence interval of R. Analysis of a simulated data set has also been presented for illustrative purposes. Monte Carlo simulations are performed to compare the different proposed methods.

Abstract: This study aimed to reveal the problems faced by the disabled women in Saudi Arabia and the relationship of these problems with a number of variables such as: type of disability, severity and history of disability, in addition investigating the differences in the level of the problems faced by the disabled woman and non - disabled ones, as well as differences between the minor problems between them. As the null hypothesis of the study was formulated with the purpose of verifying its validity according to such variables. In order to investigate the problems of the disabled women and non - disabled ones, a questionnaire prepared by the researchers was applied on (297) disabled women and girls and (297) non - disabled ones. The study tool was standardized depending on the validity of the arbitrators. its reliability was verified by computing the coefficient of the internal consistency of the items which amounted to (0.93). After extracting repetitions and percentages of the extent of the prevalence of these problems on the disabled as well as checking of the null hypothesis of the study by using the Statistical Packages for Social Sciences (SPSS). The study findings showed statistically significant differences in the problems of the disabled women pursuant to the whole variables of the study. They also showed statistically significant differences between the problems faced by the disabled woman and non - disabled ones. Based on the study results the researchers presented a number of recommendations the most important of which are as follows: the right of the disabled woman in education, labor and social participation as well as community outreach for the family of the women with disabilities, and provision of community and educational programs for the disabled woman.

Abstract: This study was done on edentulous patients wearing complete dentures containing different types of artificial teeth, acrylic resin, porcelain and gold plated acrylic resin teeth, and measuring the amount of artificial teeth wear expressed in the decreases of the vertical length of the denture teeth by measuring the vertical distances between two reference points, one on the upper denture just above the first molar area, and the other on the lower denture just below the first molar area. This distance was measured using a caliper. Along the time it was observed that, the acrylic teeth had the most amount of wear followed by the gold plated acrylic teeth and lastly the porcelain teeth showed no wear observed.

Abstract: The regeneration of the amputed hindlimbs of stage (54) of tadpole larvae of Bufo arabicus was studied after amputing their hind limbs at the mid shank level. The immunomodulator Cyclosporine A (CsA) was selected to determine its effect on regeneration. Two kinds of experiments were desigened. The first of experimental design is by immersing the tadpole larvae in a solution of CsA (0.02, 0.2 and 0.5 mg/mL) for five hours daily for three consecutive days, starting the treatment twelve hours after amputation. The second one is by intraperitoneal injection of CsA solution (0.02 and 0.2 mg/mL) administering 1 µ of CsA solution every other day starting from one day pre-amputation to day eleven post amputation. Regarding the effect of CsA on regeneration on stage 54, CsA significantly promoted regeneration in both kinds of experiments(immersion and injection), and this effect was dose-dependent. The regerative ability increases with increase of CsA concentations. Significant number of cases regenerated complete hind limbs with five or four toes, 86.3%, 66.7% and 100% of CsA treated cases (0.02, 0.2 and 0.5 mg/mL respectively) versus 45% of control cases when treated by immersion. In the other experiment, which is by injection, 90.5% and 93.3% of CsA treated cases (0.02 and 0.2 mg/mL respectively) restored hind limbswith five or four toes versus 45% of control cases. Histologically, CsA was associated with acceleration in the processes of dedifferentiation, differentiation and histogenesis in comparison with their control counterparts. Moreover, CsA treatment delayed the dermal differentiation underneath the epithelium. An observation which certainly favors regeneration as the absence of dermis allows direct communication between the above epithelium and the underlying cells for better blastema formation. CsA tratment in both experiments was also associated with early dedifferentiation of mesenchyme cells forming a well-formed blastema, and early differentiation of skeletal elements of the regenerates in compaison with their control counterparts. Adminstration of CsA to the tadepole larvae (54 stage) by injection resulted in better regenerative outcomes than adminstration by immersion. CsA significantly promoted and accelerated regeneration of their hind limbs after ambutation at the mid shank level. In addition, CsA effect was dose-dependent. We also consider that these data will give us deeper insights on the mechanisms taking place in higher vertebrates and in human.

Abstract: Cloud computing and the underlying virtualization technology is becoming more and more popular, and valuable information stored inside cloud computing environments are increasing at an alarming rate. As a result, APT attacks that target the information are also increasing. Because the key element of APT attacks is the rootkit that provides stealth, rootkit detection is an effective defensive measure against APT attacks. In this paper, we discuss how to apply VMI (Virtual Machine Introspection) techniques to detecting rootkits in virtualized environments, and use the insights gained to design an effective and efficient rootkit detection system.

Abstract: The avian stomach was a muscular organ, located between the esophagus and the intestine and it was consisted of two parts; the proventriculus and the ventriculus as reported in many text books and previous articles. A morphological study of stomach was carried out, grossly and under light microscopy on ten adult normal healthy Eurasian Hobbies. The stomach was constituted by two chambers: proventriculus and gizzard. The proventriculus was elongated fusiform shaped organ and extended from the level of 2nd intercostal space to the level of 4th rib, while the ventricular resembles a biconvex lens and was extended from the level of 4th rib to the level of 7th rib. There is no any proventricular papilla on the gastric epithelium surface. Both, the mucous tunic of the proventriculus and of the ventriculus present folds were lined by simple columnar epithelium. The tunica mucosa of the proventriculus was extensively folded due to the presence of well-developed longitudinal muscle bundles. The Eurasian Hobby stomach ischaracterized by the absence of the isthmus. There are fourventricular muscles that radiating from a powerful fan-shaped tendinous center; two thick and two thin muscles. The luminal surface of the ventriculus have cuticle, which was sloughed and shed small fine area around the pyloric opening and very thin membrane and highly closely adherent to the lining surface of gizzard. The gizzard was separated from the small intestine by a slit-like ventriculo-duodenal opening, which guarded by the very small pyloric sphincter in addition to the pyloric valve which consists of two small folds.

Abstract: Surgical site infection is the second most common health care-associated infection among women undergoing cesarean section. In this study we aimed to determine the role of prophylactic antibiotic treatment given to women when undergoing a cesarean delivery in decreasing the incidence of wound infection. A retrospective cohort study at Madinah Maternity and Children Hospital, Obstetric and Gynecology department, Madinah, Saudi Arabia, was conducted from December, 2011 to December, 2013; where 8544 medical records of women delivered by cesarean section were reviewed and the rate of surgical site infection during the year 2012 was compared with its rate during the year 2013. Total number of cesarean section cases complicated by surgical site infection in 2012 was 167 cases. During 2013 (after administration of prophylactic antibiotic to all women delivered by cesarean section), 109 cases were complicated by surgical site infection among 4470 delivered by cesarean section. Statistical analysis shows clearly that infection rates were significantly different (p<0.001) between year 2012 and year 2013; with higher rate of infection in the year 2012 which was 4% compared to 2.4% during the year 2013. Enterococcus spp. were the highest isolated organisms while, Streptococcus spp. was the least isolated organisms among isolates. 16% of isolates showed resistance to ampicillin, while, all isolates were 100% sensitive to both gentamicin and vancomycin drugs. This indicated that, surgical site wound infection incidence was significantly reduced after the administration of prophylactic antibiotics for cesarean section, beside; infection control procedures are working and also improving from month to month.

Abstract: Hesperidin (HSP) is a natural plant extract which has various effective biological activities. HSP showed promising schistosomicidal properties against adult worms of Schistosoma mansoni (S. mansoni) both in vivo and in vitro. The aim of the present study was to evaluate the in vivo schistosomicidal effects of HSP on juvenile and adult stages of S. mansoni concerning parasitological, pathological and immunological parameters in murine model of infection. Swiss albino mice were used to achieve this aim. They were classified into 7 groups (10 mice in each group): group I which included normal control mice, group II which included infected untreated control mice (IU), group III given early HSP treatment, beginning on the first day of infection, group IV given early HSP+PZQ, group V given late HSP treatment, starting at the 4th week post-infection, group VI given late HSP+PZQ and group VII given PZQ alone. The highest reduction percentages of worm burden and tissue egg load were recorded in groups IV, VI and VII. The same groups showed the highest significant decrease in percentage of immature and mature ova and the highest significant increase in percentage of dead ova. Early HSP treatment gave the highest significant reduction in both granuloma number and diameter. There was significant increase in IgG level in response to S. mansoni soluble worm antigen protein in all treated mice groups. Also, early HSP treatment revealed the highest decrease in serum levels of IL-6, IL-12 and TNF-α and the highest increase in serum level of IL-10, while both early HSP and early HSP+PZQ treatments showed the highest decrease in serum level of IFN-γ. In conclusion, HSP treatment achieved promising schistosomicidal activities, especially when given early after exposure to S. mansoni infection, in addition it alleviated hepatic pathology by affecting some cytokines involved in granuloma formation.

Abstract: Obesity was identified as a worldwide health care problem towards the end of the 20th century. Obesity is defined as an unhealthy excess of body fat results from genetic, metabolic, behavioral and environmental factors. Leptin plays a pivotal role in regulating the energy balance and fat storage by its receptor. Single nucleotide polymorphisms of leptin receptor gene may play a role in the pathophysiology of human obesity. In this study, the association between the OB-R gene polymorphism and obesity in Jeddah city population was evaluated by determining the distribution of allele's frequency of the leptin receptor LYS109ARG polymorphism (rs1137100) in 123 volunteers (60 males & 63 females) aged between (15-60 years). Each gender was divided into three groups according to body mass indexnormal "control", overweight and obese. Genotypes were determined for all subjects by using polymerase chain reaction , followed by a cut using restriction enzyme . When comparing between the body mass index (BMI) of AA and AG genotypes, a significant difference (P=0.001) was observed. Also, there was a significant increase in AA genotype compared to AG genotype in female obese (OR=0.14, 95%CI: 0.03-0.70, P=0.01). This result suggests that genetic polymorphism of leptin receptor gene (LYS109ARG) may play a role in female obese.

Abstract: In order to explore the possible toxicology mechanism of MC-LR, Chinese hamster ovary (CHO) cells were cultured in vitro to determine the effect of Microcystin-LR (MC-LR) on cell cycle. After treated with MC-LR(0, 2.5, 5, 10μg/ml) for 24h and 48h, the cell cycle distribution profiles were determined by propidium iodide (PI) combined with flow cytometer. The results of fluorescent staining showed that after exposed to MC-LR for 24h, the percentage of CHO cells in G2/M phase accumulated from 3.11% to 15.67%. After exposed to MC-LR for 48h, the percentage of CHO cells in G2/M phase accumulated from 4.9% to 22.24%. CHO cells in G2/M phase accumulated significantly (P<0.05) in the groups of MC-LR compared with the control group (0μg/ml). There was a concentration dependent increase of cells in G2/M phase with a concomitant decrease of the cells in S and G1 phase. In short, MC-LR induced cells cycle arrest in G2/M phase. These results suggest that MC-LR could block the cell mitosis, which may be associated with disorders of apoptosis-related proteins.

Abstract: In this research, the optical effect and contact area characteristics of extended gate field effect transistor (EGFET) based on tin oxide/indium tin oxide (SnO2/ITO) sensing gate were investigated. This separate structure EGFET is formed by dividing an ion sensitive membrane from the field effect transistor. Accordingly, the field effect transistor does not need to put into solution, so we can realize the pure characteristics of optical of SnO2/ITO sensing film. The instantaneous variation of output voltages are linear increase as the light intensity with a slope of 0.033mV/kLux. We realize that a traditional pH-ISFET sensitive film such as Si2N3, SiO2, Al2O3 and Ta2O5 could not be an available sensitive film in EGFET. To interpret this phenomenon, a simplified equivalent circuit was used to understand the impedance effect of an EGFET.

Abstract: Indoor location service is gaining significant interest due to the wide spread of smart phones and the potential for various location-based services. The Wi-Fi fingerprint-based method is the most widely used approach, but its major problem is the cost of radio map construction and management. In this paper, we present an indoor location service system where the radio map is automatically generated and updated by user participation. The initial input to the system is the names of reference locations. Users participate in building and updating signal fingerprints at locations. To promote user contribution, candidate locations are shown to the users so that users can easily give feedback to the server. The proposed system does not require manual site-surveying, and it does not rely on propagation models or dead reckoning for estimating location. Measurements in an office building show that user feedback can significantly improve the localization accuracy.

Abstract: One of the most common methods for founding on expansive soil is the use of sand replacement cushion with great depth to minimize the harmful effect of expansive soil. In some cases the sand cushion failed to achieve the required compaction ratio needed to support the applied loads. The use of a poorly cemented sand layer beneath foundations is commonly used instead of re-compaction of the sand replacement layer. The objective of this research paper is directed towards investigating experimentally the behavior of cemented sand under the effect of circular footing on weak sand cushion. A laboratory experimental work program was carried out using model circular footing to investigate the effect of cemented sand on the performance of circular footing on loose sand cushion. The main parameters affecting the bearing capacity and settlement of the cemented sand are studied in this investigation. These parameters include footing diameter, thickness of both cemented layer and loose sand cushion. The stress-settlement relationships are used to specify the ultimate footing bearing capacity. It was found that the presence of a top rigid layer significantly increases the bearing capacity and decreases the settlement of the footing. The critical depth of cementing upper sand layer after which increasing depth of cementation has no effect on increasing bearing capacity was determined.
