Abstract: This study is about the possible effects of particulates air pollution on traffic wardens, especially on their lung function using peak expiratory flow rate (PEFR) as a measure. A sample of forty nine traffic wardens at the busiest road junctions in the metropolis of Port Harcourt, Nigeria, were selected at random and tested for their PEFR. The ambient particulate matter at the heights of between five to six feet where they are expected to breath was measured. The study determined peak and off-peak periods of concentration by taking a thirteen hour measurement of the various particulate fractions (i.e., PM1, PM2.5, PM7, PM10 and TSP) in the ambient air. Particulates concentrations ranged between 46 – 358 µgm-3 and the Nigerian and WHO standards were exceeded in many instances. The mean PEFR of wardens who worked indoors was 419.2 Lmin-1, while for those who worked outdoors it was 474.7 Lmin-1. Taking 450 Lmin-1 as a threshold, since normal lung function lies between 350 and 450 Lmin-1., wardens with the least PEFR are those with the greatest exposure to particulates and the length of exposure was related to the number of years in service and age. Evidence in the literature suggests that particulates stimulation of the respiratory system is responsible for the reduced PEFR of exposed subjects. Wardens working outdoor should be made to work lesser hours and no group of persons in the police force should be made to work outdoor exclusively. There should be rotation of duty to ensure that no person is unduly over exposed to particulate concentration to avoid reduction in PEFR which may predispose such persons to respiratory illnesses. Standards and limits for particulates exposure in work places, including outdoors should be introduced to safeguard the health of wardens and the population as whole.

Abstract: The experiment was carried out to study the performance of two aman rice varieties (BRRI dhan31 and BRRI dhan41) under different planting methods (line sowing with sprouted seeds by drum seeder, haphazard transplanting and transplanting in line). Both the variety and planting method had significant effect on crop characters plant height, number of total tillers m-2, effective tillers m-2, grains panicle-1, sterile spikelets panicle-1, total spikelets panicle-1, grain yield except panicle length and 1000-grain weight. BRRI dhan41 produced the highest grain yield (4.06 t ha-1). Line sowing method with sprouted seeds by drum seeder showed better performance in respect of no. total tillers m-2 (415.81), effective tillers m-2 (401.85) and grain yield (4.80 t ha-1). The highest no. of total tillers m-2 (421.12), effective tillers m-2 (410.65) and grain yield (5.08 t ha-1) were recorded due to effect of the interaction of line sowing method with sprouted seeds by drum seeder and the variety BRRI dhan41.

Abstract: Physical activity considers as factor to make the urban neighborhoods more vibrant and alive. Besides of the physical activity’s advantages for urban neighborhoods in urbanization fields, the health advantages highlighted by many scholars as one other important advantage of existing physical activity in urban neighborhoods. Based on the significance of physical activity in urban neighborhoods, this review article aims on establishing the factors associating with physical activity improvement or failures in urban neighborhoods. To do so, 25 research articles associating with physical activity in urban neighborhoods were evoked and reviewed. Despite of the existing result’s inconsistencies, the significant factors affecting physical activity in urban neighborhoods are revealed. Most of undertaken articles that were focused on statistical strategies were validated and reliable physical activity is standardized. Moreover, the possible moderation of effects are surely investigated and warranted.

Abstract: We propose a tracking algorithm based on image classification involving online feature weighting. The algorithm uses automatically produced general Haar-like features through feature extraction and feature selection using an online-built object model, and combines Principal Component Analysis (PCA, a generative method) and Fisher“s Discriminative Analysis (FDA, a discriminative method). That is, we first train the Fisher classifier to distinguish the foreground candidates from background. Then target matching is performed based on similarity with PCA codes of the candidates in feature vectors. The discriminating function of Fisher classifier is a linear combination of the weighted feature values. We also propose a feature discriminative power evaluation equation based on multi-class FDA which gives more discriminative results between the foreground and background. Both the PCA and FDA are online updated to adapt to variation in the images of the tracked object over time, e.g., by noise, occlusion, or a cluttered background. Experimental results show that the proposed method improves detection accuracy when compared with some competitive algorithms.

Abstract: Castleman’s disease (CD) is a rare benign disorder characterized by hyperplasia of lymphoid tissue that may develop at a single site or throughout the body. CD comprises at least two distinct diseases (unicentric (localized) and multicentric) with very different prognoses. Surgery remains the main treatment for resectable unicentric CD. The two principal histologic subtypes of CD are hyaline-vascular, plasma cell variants and a mixed variant. We report two cases of unicentric Castleman’s disease (UCD) treated at our institute that mimic retroperitoneal neoplasm and cured by surgical excision. We review the literature on the management of this rare entity and concentrate more on UCD.

Abstract: The main difference between “traditional” epistemology and virtue epistemology is outlined. The relevance of virtue epistemology to philosophy of education is set out. The ramifications of two main branches of virtue epistemology – virtue reliabilism and virtue responsibilism – for education are analyzed. The significance of cognitive agency for knowledge is shown. The importance of first-order and second-order cognitive faculties is maintained. The role of testimonial knowledge for education and problems it poses for virtue epistemology is exposed. It is proposed that testimonial knowledge could be virtuous provided that it is attained in epistemically friendly environment. The status of intellectual autonomy as a cardinal intellectual virtue is defended. The goal of nurturing intellectual autonomy in education is explained. The problem of educating intellectual virtues is discussed. Contemporary virtue epistemology is compared with Russian tradition of “developmental education” of Elkonin and Davydov. The role of mutual cooperation between students for attaining intellectual virtues is stressed.

Abstract: Objective: Redefinition and classification of vitreous base avulsion (VBA) adapt to the clinical need for diagnosis and treatment of it. Design: A retrospective consecutive case observation. Participants: Ninety-eight consecutive patients (98 eyes) with VBA included 23 patients with closed-globe injury, 46 with open-globe injury, 17 with rhegmatogenous retinal detachment, 6 with proliferative diabetic retinopathy, 4 with vitreous hemorrhage caused by miscellaneous diseases, and 2 with acute retinal necrosis syndrome. Methods: The ora serrata and the pars plana were examined carefully using a slit-lamp biomicroscopy combining with depressing Goldmann three-mirror lens before operation and observed under the surgical microscope with scleral indentation during the scleral buckling or vitrectomy surgery. The samples obtained from the operations were examined histopathologically. Main outcome measures: The VBA was classified into the acute and the chronic according to the happening times and was subdivided into two subtypes of surgery and eye trauma based on the causes. The acute VBA was defined that the avulsion concurred at the same time of trauma and surgery, and the chronic that was occurred after one month of open-globe injury and surgery. Results: The VBA was acute traumatic in 24 cases, acute intraoperative in 64 cases, chronic posttraumatic in 8 cases and chronic postoperative in 2 cases. The histopathology presented that a sheet of the nonpigmented epithelium linked to the peripheral retina in all specimens of acute traumatic and intraoperative VBA, but that the pigmented epithelium was found in the some cases. The samples of chronic posttraumatic and postoperative VBA were similar in the morphology, in which the retina, ciliary epithelia and proliferative fibrous tissues could be detected. Conclusions: The clinical manifestations of VBA can be divided into two types as acuteness and chronicity and two subtypes as trauma and surgery. They are all attributed to an acute or chronic vitreous traction on the vitreous base. It is most common in the cases of eye trauma, vitreous surgery and cataract surgery with vitreous loss.

Abstract: The online information explosion has created great challenges and opportunities for both information producers and consumers. Understanding customer’s feelings, perceptions and satisfaction is a key performance indicator for running successful business. Sentiment analysis is the digital recognition of public opinions, feelings, emotions and attitudes. People express their views about products, events or services using social networking services. These reviewers excessively use Slangs and acronyms to express their views. Therefore, Slang's analysis is essential for sentiment recognition. This paper presents a framework for detection and scoring of Internet Slangs (DSIS) using SentiWordNet in conjunction with other lexical resources. The comparative results show that proposed system outperforms the existing systems.

Abstract: Neonatal Apgar reduction, at the beginning of childbirth, is one of the most important causes of postnatal death. The aim of this study is to compare the effect of thiopental with that of propofol on neonate Apgar cesarean and on their mothers hemodynamics. This prospective and double-blind clinical trial study was carried out on 108 women, who were divided in group I or group II according ASA (American Society of Anesthesialogist), whom were selected for cesarean section in Jahrom university of medical sciences hospitals. Anesthesia induced with thiopental and propofol in one group in another then these parameters were recorded: time interval of anesthetic induction to extraction of neonate Apgar score, 1 and 5 min after birth, the blood pressure of anesthetic induction, were delivered by a blood pressure problem before of endotracheal intubation, blood pressure were delivered by a after of neonate after extraction and were delivered by a pulse rate of anesthetic induction were delivered by a before and after. The results were analyzed using Spss software and T test. No statistically significant differences were found for vitality between the two groups of neonates (P > 0.05) but the hemodynamic changes of mothers showed significant differences in the two groups (P < 0.05). The result of this study showed that propofol can be more appropriate than thiopental for induction of anesthesia in caesarean section and has no effect on the hemodynamic changes and newborns Apgar score.

Abstract: Egypt is importing about 640,000 tons of fish annually. It costs Egyptian economy about 250 million dollars. Sea coast around Egypt is about 2,000 Km. To overcome this problem, about 200,000 acres of fish farms were constructed during the last decade, but due to explosion of population number to 86 millions, these farms were not adequate for solving this problem. Due to unavailability of freshwater resources, fish farms could not be increased. Construction of Qattara Depression project with filling of sea water from Mediterranean Sea may increase fish production from the resultant lake. The surface area of the lake will be around 12,100 square Km. A research review is needed to know the exact production of fish from the presumed lake after finishing Qattara depression. This study will be done in laboratory aquaria in National Research Center and also in cement ponds in one of the governorates on the North Sea coast (Kafr El-Sheikh). A field study will be done in 5 earthen ponds. It is predicted that fish production from the project will be around 150,000 tons of fish without fertilization and about 500,000 tons of fish with fertilization Aim of this study Is to asses fish production in the presumed lake of Qattara Depression with or without fertilization

Abstract: This paper describes the development of a Ubiquitous learning System (ULS) based on adaptive media streaming techniques. The ULS system has been implemented as a core system within the Ubiquitous Learning Environment used at the College of Computer Science and Engineering, at Taibah University. Students are able to access the various learning services and applications using smart phones, PDAs, laptops, or any mobile devices within the wireless network coverage of the College. Dedicated Mobile Learning Applications and Services have been developed for both students and instructors to use in the Ubiquitous learning environment. Due to the increasing penetration of smart phones and tablets alike, and the enormous usage of video media content nowadays, the need to develop a dedicated video streaming system dedicated to Ubiquitous learning becomes a necessity to support and attract students to use and interact with relevant multimedia learning objects and resources made available at the college. The ULS is an adaptive system composed of three main services: Video-on-Demand (VoD), scheduled programs (WebTV), and Live Event. Depending on the client type, PC-based or Handheld devices, two different streaming techniques are used to ensure reliable media delivery in an efficient and adaptive manner. PC-based clients are characterized by high hardware performance and relatively stable bandwidth compared to handheld devices. In such case, traditional streaming using RTSP over UDP is used.

Abstract: In digital communications, Steganography is defined as the science of embedding secure data into digital media when transferring the digital media through insecure channel. Human Visual System (HVS) and statistical methods must not be able to detect the embedded data. We have developed new technique based on feature extraction. A Gaussian pyramid is created with multi-resolution images, for each image the features are extracted and then the multi-resolution images are combined to create a complexity measure for each feature. We have selected the region with the highest complexity to embed the secure data. Results show high quality of the stego-images when compared with the similar methods.

Abstract: The world is facing many global challenges, such as sustainable production methods, and adapting to climate change. As a result of the climate change and the developing of the living standard of the people, the pressure on energy and water resource is increasing, and pollution of the air and water as well as the degradation of land are increasing in a tremendous way and will continue to grow. In Jordan, as a poor water country, a low quantity of rainfall, especially in southern Jordan, is a major cause of drought. Consequently, producers will face a bigger productivity drop. Cultivating special plants to produce energy and producing biofuel are considered alternative energy sources. Analysing the use of these alternatives is very complex because the technical issue, environmental, social and economic impact should be assessed. Nevertheless, using scare resources, such as water, and the impact on food security are other variables that should be considered. This study focuses on producing biofuel in an agricultural area from an economic point of view, with specific attention on food and water security as well as the environmental impact. The study depended on a case study that applies planting Jatropha to produce biofuel. As a conclusion the producing oil from Jatropha has high potential to be profitable. Socially and environmentally of producing biofuel from Jatropha is will not be on competition in using the resources with other crops, because it could be planted in marginal land and using low quality water. The growing global demand for liquid biofuel has been seen as a way to create new employment opportunities through the work in the farms or in the biofuel factories, thus leading to increase income generation and rural development, in addition to saving the energy from other sources.

Abstract: The leaf powder of desert rose (Adenium arabicum) was supplemented orally in the diet to hypercholesterolemic male Albino rats for 8 weeks to test its antioxidant activity and its effect on lipid peroxidation. Eighteen male rats weighing 180-200 gm were divided into three groups. The first group is untreated control group fed normal diet, the second group was fed 2% cholesterol in diet to induce hypercholesterolemia (positive control group), and the third group was fed 2% cholesterol (to induce hypercholesterolemia) and treated with 500 mg/kg body weight rose leaf powder for 8 weeks. The positive control group showed a significant increase in lipid peroxide and a significant decrease in antioxidant enzymes; glutathione reduced (GSH), serum glutathione reductase (GR) and serum superoxide dismutase (SOD) activity in the serum and tissue homogenate. Moreover, histopathology of liver and kidney in the positive control group showed histopathological changes compared with the negative control ones. Treating the hypercholesterlemic rats with desert rose leaves increased the antioxidant enzyme activity and decreased lipid peroxide. In addition, the histopathology of the studied organs was also recovered and seemed normal after desert rose treatment. In conclusion, desert rose leaves have an important anti-oxidant activity, decreased lipid peroxidation and improved the tissues of the kidney and liver of hypercholesterolemic rats under study.

Abstract: Background. The Acute Dialysis Quality Initiative Group has published a consensus definition/classification system for acute kidney injury (AKI) termed the RIFLE criteria. The Acute Kidney Injury Network (AKIN) group has recently proposed modifications to this system. It is currently unknown whether there are advantages between these criteria. Methods .We interrogated 100 Adult critically ill cirrhotic patients for which RIFLE and AKIN criteria where done. Aim of the work. Comparison of RIFLE and AKIN criteria for AKI in critically ill cirrhotic Patients. Results. This study was performed on 100 cirrhotic patients admitted to Intensive Care Unit in the hospital of Theodore Bilharz Research Institute. According to the RIFLE classification, there were 40 Non-ARF patients, 22 RIFLE-R patients, 8 RIFLE-I patients and 30 RIFLE-F patients. According to AKIN criteria there were 38 Non-ARF patients, 24 (Stage 1) patients, 8 (Stage 2) patients and 30 (Stage 3) patients. The Non-Survivor group had a significantly longer duration of hospital stay than the Survivor group. There was insignificant correlation between RIFLE / AKIN score and the LOS (length of stay) as the R= 0.135 and p value = 0.179. RIFLE and AKIN classifications studied in this study were highly predictive of poor outcome in cirrhotic patients at different cut-off points as studied by ROC curve analysis. The patients’ ages were ranging from 43 to 73with a mean age of 59±8.06 years. Conclusion. Compared to the RIFLE criteria, the AKIN criteria do not materially improve the sensitivity, robustnessand predictive ability of the definition and classification ofafter admission to ICU.

Abstract: Congruency has been a central concept in certain fields such as job design work values, organizational goal, and many others. There are a few factors that suggest that agreement between supervisors’ and subordinates’ are critical determinants of the liking and exchange processes. This research incorporates a basic distinction between the agent and target. Three hundred and eighty-five pairs of Malaysian managers and executives voluntarily participated in this study. The findings suggested that when both supervisors and subordinates were perceived to have position power, the use of hard influence tactics was most apparent and vice versa. Implications of the findings, potential limitations of the study, and directions for future research were discussed further.

Abstract: Analysis of studied literature showed that there were only single, sometimes conflicting data on existing birds’ thrombodefensins, their antimicrobial activity. The problem of birds’TD influence on persistent properties and microorganisms’ ability to form biofilms hasn’t been studied yet. This determined purposes of our research – the aim is to study some functional properties of antimicrobial peptides extracted from hens’ platelets. Objective. Antimicrobial peptides were extracted from various tissues of vertebrates and human, special significance is taken on by the antimicrobial peptides which were extracted from platelets and have antibacterial, antiviral, antimycotic and anticancer activity. Materials and methods. At the terminal stage of fattening acid-soluble proteins of broiler chick’s platelets were got by means of the method of low-pH extraction [6]. Protein content in these low-pH extracts were determined with the method by M.M. Bradford (1979) with using of CoomassieBrilliantBlueG-250 dye (SIGMA, Germany) [7]. Antimicrobial properties of the acid-soluble proteins from platelets were estimated in vitro by means of the plate method in the case of Gram-positive microorganism Bacillussubtilis83. The concentration inhibiting growth of 50% of colonies compared to the control was considered as the minimal bactericidalconcentration (MBC). The preparation activity was re-counted taking in account the protein content in low-pH extract. Spectrum of antimicrobial activity of acid-soluble proteins from platelets was determined in the case of such cultures: Bacilluscereus, Micrococcusluteus, Staphylococcusaureus, Enterococcusfaecalis, EscherichiacoliК12, Klebsiellapneumoniaе 278, Enterobactercloacae, Candidaalbicans. Influence of various TD concentrations on anti-lactoferrin activity (ALfA) was determined on thesecultures: Escherichiacoli К12, EnterococcusfaecalisиCandidaalbicans. Studying of TD persistency regulation was accomplished in two stages. In the first stage we extracted clones by plating 24 hours’ culture on solid nutrient medium according instructions by Miller (1976) [4]. Then we chose a clone with the highest level of ALfA. In the second stage we studied ingluence of TD dilutions on ALfA of microorganism by co-incubation. ALfA of microorganisms was determined by means of complex of apparatuses for enzymeimmunoassay by “STAT FAX” using sets for lactoferrin determination “Lactoferrin-EIA-BEST” by “Vektor-BEST”, which was evaluated in ng/ml [2]. Estimation of low-pH platelet extract influence on the ability to form a biofilm we did in vitro in the case ofcultures capable of biofilm formation: Enterobactercloacae(3 strains), Enterobacteragglomerans, StaphylococcusaureusР 209, Klebsiellapneumoniaе 278, Сandidaalbicans(3 strains) [40]. Activity level was counted as ratio A492test/A492control. Measure more 1,1 were considered as a positive result. Results and Discussion. Summing up our findings we should note: at first, there are antibiotics owning a wide spectrum of antimicrobial action in hens’ platelets, at second, platelet cationic proteins are capable to change biological properties of microorganisms, these properties determine their interaction with macroorganism, which can be used in working out a new class of antimicrobial preparations in perpective. Annotaion: In platelets of agricultural birds (broiler chicks) there were discovered antimicrobial peptides–thrombodefensins (TD), which possess a broad spectrum of action in the case of Gram-negative, Gram-positivebacteria’s forms and Candidaalbicans.Thrombodefensins exert multidirectional influence on biological characteristic of microorganisms: they inhibitanti-lactoferrin activity (ALfA)and exert modifying influence on biofilm formation.

Abstract : This study examined the effect of acetic acid, carbon dioxide and ground mustard, on the microbiological and chemical quality of raw minced beef storage at 4 °C. The results showed that addition of acetic acid, carbon dioxide and ground mustard  significantly delayed the proliferation of aerobic plate counts, Enterobacteriaceae, psychrotrophic counts, and Total Coliform count (MPN)  and extended the shelf life of the product up to 6,10 and 12 days, respectively, versus 4 days only for control. Ground mustard was the most effective to decontaminate the minced beef being effective in preventing the growth of a wide variety of microorganisms. Therefore, ground mustard could be utilized successfully to reduce the microbial growth, maintain the chemical quality, and extend the shelf life of minced beef held under proper refrigeration.

Abstract: The Kazakhstan notariate in recent years underwent the considerable changes caused by new public conditions. It passed the significant historical period, during this period the Law of the Republic of Kazakhstan “About notariate” of July 14, 1997 No. 155 and set of subordinate acts were accepted, thus normative basis is completely updated. Despite this, today's condition of regulatory and legal framework demands to create new conceptual views which have to meet the modern legal and public requirements. During the modern period in the Republic of Kazakhstan a controversial question is notariate recognition as public institute, on the basis of it notary officer should be given the status of the independent representative of the state. In turn it pursues the aim to refuse licensing and granting of notary with powers from the state. The aforenamed problems lead to emergence of various opinions in society, in consequence of which to continuous change of legal bases of notariate.

Abstract: Humic substances composed of humic acid (HA), fulvic acid (FA) and humin (HM) represent the most microbially recalcitrant and stable reservoir of organic carbon in soil. In order to identify the chemical compositions, humic substances were extracted from normal, (non-saline), saline, alkaline and newly reclaimed salt affected soils collected at0-30 cm surface layer during the summer of 2010. Elemental analysis, solid-state carbon-13 nuclear magnetic resonance (13C-NMR) acquired with cross-polarization magic-angle spinning (CPMAS) and infrared (IR) spectroscopy measurements were used to characterize the chemical composition in the humic substances. Variations in chemical, functional groups and spectroscopic measurements were observed among the extracted humic and fulvic acids. More humic substances were extracted from the normal soil than other soil types, with the majority being humic acid. Data from elemental analysis and 13CNMR spectroscopy indicated that humic and fulvic acids extracted from the normal and saline were more aromatic than those of alkaline and newly reclaimed soils. Fulvic acid extracted from all soils contained mostly aliphatic, O-substituted alkyl, and carboxylic groups and small amounts of carbonyl groups. Based on the spectroscopic analysis of IR Spectroscopy, no significant differences were detected among different types of humic substances. It cleared that humic acids extracted from the newly reclaimed soil were less humified than those of the other soils. Therefore, it is important to look for the suitable management practices for each type of soils.

Abstract: This work presents a study of natural radioactivity levels and radiation hazard indices for dust storms samples from Qassim region, Saudi Arabia. Distributions of naturally occurring radioactive materials (NORM) of 226Ra, 232Th and 40K were determined using NaI (Tl) γ-ray spectrometry. The Radiological effects from 23 samples were estimated. Activity concentrations were determined for 226Ra (from 1.8 to 102 with average value of 10 Bq kg-1), 40K( from 1.5 to57.6 with average value of 8.1 Bq kg-1) and 232Th (range from 88.9 to 433.6 with average value of 306.6Bq kg-1). To assess the radiological hazard of the natural radioactivity in the samples, the radium equivalent activity (Raeq), Gamma Index (Ig) and the absorbed dose rate were calculated and found to be within those values recommended by the International Commission on Radiological Protection (ICRP1990) as the maximum annual dose to members of the public. This study provides a baseline map of radioactivity background levels in the Saudi environment and will be used as reference information to assess any changes in the radioactive background level due to geological processes.

Abstract: Literacy and adult education are an essential objective for realizing development and increasing production for any country. Egypt is one of the countries that still has high rate of illiteracy is around 30% of the adult population (age range 15-45). In Saudi Arabia the distant regions faces a similar challenge. Traditional literacy classes proved not to be very effective in solving the problem. Meanwhile mobile phones are the fastest growing technology devices worldwide and surprisingly they are used also by people with very low level of literacy. In this paper we introduce a literacy education application for mobile devices that implements an interactive process where the user practices the reading and writing skills with guidance from a dedicated teacher. We introduce novel mobile technologies that can foster the acquisition of reading and writing skills for illiterate citizens using Automatic Speech Recognition (ASR) and Automatic Handwriting Recognition (AHR) techniques. This poses several challenges: first, the speech recognition for an illiterate’s reading is expected to have severe miss-pronunciations and deviation from the reference models. Also hand writing training requires dealing with the irregular strokes of the illiterate’s handwriting with dis-fluent hand movements. Moreover running ASR in noisy environments and using a mobile touch screen for handwriting practice are other complexities that need to be handled. Finally, the application needs to fit with the limited computational resources of the common mobile devices.

Abstract:文本框: IV
 
 Infection Control (IC) and standard precautions (SPs) is evidence-based practices that can reduce the risk of transmission of microorganisms. IC education is a fundamental component of the nursing curriculum. The present study aimed to Assess knowledge, attitudes and sources of information among nursing students toward infection control and standard precautions. Subjects and methods A convenient sample consisted of 96 nursing students. Setting: The study was conducted in Umm Al-Qura University, Faculty of Nursing, Saudi Arabia. One tool was used comprised three parts. Part 1: General data. Part 2: Knowledge assessment questionnaire about 5 different domains of IC and SPs. Part 3: Attitude assessment questionnaire used towards current curricular sufficiency, and training needs related to IC and SPs. Results The current study revealed the total score for knowledge was 38.71±7.02 (out of 53 points) with a total of 44 out of 96 students (45.83%) of students scored ≥ 40 out of 53 points which is considered to be acceptable. Sharp injuries, indications and the use of gloves and alcohol-based hand rub, showed the least knowledge scores. It is concluded The main source of information for students was the curriculum. Nursing students were satisfied with the current curricular content although they reported there need for further training and education regarding IC& SPs. It was recommended that teaching must be strengthened, curricular reform and training are required to fulfill students' knowledge deficiencies related to in IC & SPs to protect students and their patients.

Abstract: Objective: Computed tomographic angiography (CTA) has surfaced as a valuable non-invasive diagnostic modality in the management of intracranial aneurysms (IAs). In this study, the author reports the accuracy of CTA versus digital subtraction angiography (DSA) in the assessment of patients with IAs. Methods: A retrospective review was conducted for all patients investigated for IAs with both CTA and DSA using standard imaging protocols at king Abdulaziz university hospital between January 2008 and December 2013. Thirty-one patients with IAs underwent evaluation with CTA and DSA during the study period. Comparison between the two modalities included accuracy of detection of IAs was assessed. Results: Patient’s age ranged from 17 and 70 years (average 42.8 ± 7.9 years), and 20 patients (64.5%) were females. SAH was the initial presentation in 20 patients (64.5%), five patients (16%) with headache and seizures disorder had a mass lesion on CT scans demonstrating a large IAs, and CT scans were normal in 6 patients (19.4%). Both of CTA and DSA studies detected 29 IAs in 28 patients (90.3%). Three patients had no IAs detected in both CTA and DSA examinations, in one patient operated for repeated SAH with intracerbral hematoma, a small internal carotid artery blister was detected intraoperatively and clipped. Twenty-two patients (78.6%) underwent craniotomy and microsurgical clipping of IAs, and endovascular coiling was performed in 6 patients. CTA was effective in the post-treatment follow up and evaluation of IAs; however, in two patients CTA was not accurate in assessing the recurrence of the aneurysms. Conclusion: CTA provides accurate and valuable information for patients with cerebral aneurysms. It can be used alone for the diagnosis, treatment planning, and post-treatment follow up of IAs.

Abstract: Background: This research discusses the epidemiology of road traffic accidents which occurred in ghana between 2001 and 2011. The purpose of this research is to provide a snapshot of road traffic accident cases which would inform the authorities on the need to ensure sanity on the roads. Methods: A descriptive and cross-sectional study was adopted to explore the incidence of rta in ghana from 2001 to 2011. Secondary data were obtained from the Building and Road Research Institute. Results: A total of 125,681 RTA involving 150,949 victims analysed. There were 96,888 (64.19%) passengers and 40975 (35.81%) pedestrian. There were 21,283 (14.14%) fatality cases and 129,666 (87.95%) suffered various degrees of injuries. The percentage share of lives lost is 38.50% (8194) while pedestrians were 61.50% (13,089). The findings also show that only three types of vehicles such as car (46.43%), bus (15.48%) and heavy duty vehicle (13.18%) contribute 75.09% of RTA. The evidence shows that males have 1.5 times higher risk of RTA than females. Findings produced a satisfactory proof that the ages between 1 and 40 contribute 65.16% of RTA. It was also shown that the second half of the year produces a higher accident rate and at a peak in December. Conclusion: RTA is a treat to lives and properties and every effort must be made to salvage the situation.

Abstract: This article examines dynamic misconceptions and conceptual change in technology behavior in the context of a study conducted to 13 Saudi female graduate students regarding their misconceptions about PowerPoint and the interventions used to correct these misconceptions. A conceptual change model is adopted to measure any shift in belief after intervention. A pilot study was conducted to verify the validity and reliability of the belief instrument. The results indicate positive outcomes in conceptual change and technology behavior. The study confirms “misconception” as a pre-determinant of misuse, and recommends that “misconception” be included in change models to better explain usage behavior and resistance to change.

Abstract: In this paper we define the concept of dicardinal function, and then (co)weight, (co)densification, (co)net weight, (co)pseudo character which are able to be used in classifying of ditopological texture spaces. It is natural to ask how there are relationships between the set  ( or ) and dicardinal functions that we defined in ditopological texture spaces. Based on the question, our aim in the paper is to investigate dicardinal functions above for ditopological texture spaces. We obtain useful some results on bounds of , the set  of all -sets and the set  of all -sets by choosing the subclasses satisfying axiom  or Co- the class of all ditopological texture spaces. Furthermore, we show that (co)weight and (co)densification restrict each others.

Abstract: From 2008 to 2011, the numbers of beds and medical workers in Chinese public hospitals are increasing substantially, resulting in growing scale of such hospitals. By using weighted least squares (WLS) method and seemingly unrelated regression (SUR) method respectively, this article estimates a multi-output cost function based in 4-years balanced panel data samples, correlation between individual effects and observable regressors of sample hospitals is permitted in the model. It is shown by WLS results that economy of scale differs greatly among hospitals of different types and in different regions; SUR results show that hospitals at lower levels are more obvious in terms of economy of scale and economy of scale among hospitals in different regions does not vary much. With the growth of scale, economy of scale tends to decrease due to influence of non-observable factors like management ability. This article also indicates that attentions shall be paid to the influence of non-observable factors on parameters estimation of hospital cost function.

Abstract. In the ХІХ century the Ottoman Empire was experienced the decline process, despite it still owned the lands in Europe, Asia and Africa. At this time Bosnia and Herzegovina was the part of the Ottoman Empire and was one of the provinces of the empire in Europe. The Ottoman Empire collected different taxes from the owned provinces. In the 50-ies of the XIX century the Ottoman Government imposed new taxes to agriculture of Bosnia and Herzegovina. During collection of taxes arose many disagreements between the local population and authorities. It was shown by a lot of information in the written memoirs of that time and in the reports and records published in the Consulates of Russia and Austria in Bosnia and Herzegovina. Based on these facts, the article is devoted to research of the tax collection policy of the local authorities and imposed new taxes in the provinces of Bosnia and Herzegovina by the Ottoman Empire.

Abstract. Sealing systems of turbomachinery determine possibilities of intensification of work processes in them. Face seals are most common in high speed turbomachinery. The research objective in this article is improving calculation methods for hydrodynamic parameters of face seals. Numerical and analytical calculation methods for hydrodynamic parameters of face seal with a complex clearance form characterized by tapering and undulation have been developed in the article. The numerical method has been developed using the finite volume method and considers inertial forces. Known formulas are derived from analytical expressions of process fluid leakage through the clearance of a complex form in equating tapering and undulation parameters to zero. The developed methods are applicable for hydrodynamic face seals and for contact face seals.

L.N.Gumilyov Eurasian National University, Mirzoyan Str., 2, Astana, 010000, Kazakhstan

 

Abstract. The article examines the legal status of “alien elements” in the social structure and everyday life of cities in Northern Kazakhstan as exemplified by Akmolinsk in the second half of the 1920s. The authors provide the analysis of broad historiographic basis which includes Russian and Western European scientific literature about the specificity of studying everyday life of Soviet cities. The main historical sources are archive records which characterize methods used by “nonvoters” to return their rights: delations and applications to public authorities. The authors come to a conclusion that disfranchisement exerted a significant influence upon man’s social rank, his offspring and relatives. This is an indication of totalitarian regime establishment in the Soviet Union.

Abstract. The aim is to explore main trends of assurance of financial stability of modern small and large social economic systems by using innovative approach. The following fundamental results have been obtained: regular external changes affects substantially the performance of social economic systems, their financial stability; a social economic system is a particular object including two main subsystems; the social economic system can be structured by several hierarchic levels (microlevel, mesolevel, macrolevel); the social economic system at the macrolevel implies the combination of mutually acting business and economic subjects with the performance in production and distribution spheres, the sphere of barter (the enterprises as independent economic units represent the microlevel or small social economic systems); the financial stability of social economic systems is the latter’s ability of crisis free development at the balanced capital structure, glow of financial resources and obtaining the financial result ensuring both simple and expanded reproduction; assurance of financial stability of social economic systems should be based on the last achievements of the science of management of finances. It means in practice continuous innovations in management, arrangement of mutual cooperation with counteragents, implementation of business processes with their proper transparency; the innovative transformation of assuring financial stability of social economic systems is a well-planed development process when the system accumulates the abilities for leading counteraction to risk factors, their transformation into economic and financial benefits. It can be considered as formation of the strategic development financial development.

Abstract. It has been found out that one of the reasons of anthropogenic complex low production is degradation processes development, which manifests in the deterioration of the balance of humus, nitrogen, phosphorus and potassium in the agriculture of Mordovia Republic. Increased tension of humus balance occurs due to the sharp decrease in the number of organic fertilizers applied. It has been studied that the design of modern farming systems should be based on uniform allocation of natural complexes allowing to solve the problem of environmental improvement with minimal costs. Agricultural areas planning should take into account the structure of land, industry accommodation, recreation areas and to ensure the prevention of environmental risks.

Abstract. In the present-day practice of mining the available ways and means of reduction of technogenic arrays dust exhaust are either not effective enough or are sources of workspace pollution themselves. Alternatively, in order to solve this problem, the National University of Mineral Resources has developed the technology, the essence of which is an application of biogenic protective layer, consisting of a mixture of biohumus and sodium carboxymethyl cellulose in the ratio of 125:1, onto dusting surfaces. If compared with the known solutions, the proposed method improves the efficiency of dusting surface fixation, while forming bioproductive environment that will facilitate the creation of secondary ecosystems on disturbed technogenic arrays.

Abstract: Introduction: Today, mortalities and injuries due to traffic accidents have been confirmed as a global phenomenon. Meanwhile, mistakes and high risk behaviors by drivers, is the most important intervening factor in traffic accidents. This study is to analyze the causes of traffic accidents according to drivers’ aberrant behaviors. Methods: This cross-sectional study was conducted on 540 taxi drivers using Manchester Driving Behaviour Questinnaire in 0-5 Likert scale. After being gathered, the data were analyzed by SPSS 11.5  using Pearson Correlation and Logistic Regression. Findings: The mean score of aberrant driving behaviors was obtained 2.06 (± 0.47) and lapse obtained the highest score and driving mistakes did the lowest. As age advanced, the rate of aberrant behaviours declined (P = 0.006). Commitment of mistakes and offences was more prevalent in ages under 30 years compared to other age ranges and lapse in the individuals over 50 years was more prevalent compared to other items. The results of logistic regression indicated that all variables of DBQ are important in predicting Iranian drivers’ aberrant behaviors (P < 0.001), but intentional offences had the highest correlation. There was an inverse correlation between driving history and intentional offences and mistakes (P < 0.001). Conclusion: According to the results, it could be said that intentional offences and lapse in driving behaviors are more predictive of self-reported accidents compared to other variables. The drivers in low ages are more willing to practice aberrant behaviors due to lack of adequate skill and experience and having intrinsic excitements. By contrast, as age advances, intentional offenses declines and the rate of lapses ascends. It seems that through provision of regular, periodic training for the drivers by occupation and creating awareness, aberrant behaviors and, by extension, traffic accidents could be effectively decreased.

Abstract: Negative predictive value (NPV) is one of the important indicatives for evaluating a medical procedure. Herein, we have evaluated the NPV of 16-multidetector-row CT angiography (CTA) in comparison with conventional invasive angiography (CIA) in the diagnosis of significant stenosis. In this regard, 8 patients suspected to stenosis were investigated. They patients were undertaken CIA procedure after CTA. The obtained results show, the NPV of 50% for patient-base analysis. The findings of this study reveal that CT angiography with 16-slice scanner might be considered as an acceptable technique for rapid triage of patients. Low values of NPV reveal a moderate performance of CTA. However, due to low number of patients, the obtained results cannot be used for final decision. Hence, more is required to improve and achieve reliable results.

Abstract: Background: Taking the positive effects of the hospital information systems on patients' treatment process and organization's function into account, it is necessary to evaluate information quality provided by such systems. Hence, the aim of this study was to assess and compare information quality of hospital information systems in medical- teaching hospitals of Isfahan based on the DeLone and McLean's modified Model. Methodology: This research was applied and analytical-descriptive in nature and was performed in medical-teaching hospitals of Isfahan in 2010. Research population consisted of hospital information system's users, system developers and IT authorities selected by random sampling method. Data collection instrument was self-designed questionnaire. Questionnaires’ reliability was estimated by using Cronbach's Alpha coefficient that was found to be %94.08 and %96.8 for system users' questionnaire and system developers and IT authorities' questionnaire, respectively. Results: According to the findings of the study, the difference between the mean scores gained for information quality of all kinds of HISs and different hospitals were statistically significant, i.e. they were not the same (p<0.05). Generally, Kowsar system (new version) and Rahavard Rayaneh system gained the highest and lowest mean score, respectively. The total mean scores obtained for observing the standards stipulated for information quality was %60.2 for all hospital information systems and %60.8 for different hospitals, respectively. Conclusion: According to the results of the research, it can be inferred that based on the applied model, the levelof observing the criteria of hospital information system was rather optimum. Thus, in order to reach a completely optimum condition, it is necessary to pay particular attention to the factors improving information quality, type of activity, type of specialty and property type.

Abstract: Background and aim: Various laboratory tests with their own particular strengths and weaknesses exist for diagnosis of acute myocardial infarction (AMI). This study was conducted to determine the association of changes in electrocardiography, echocardiography and cardiac enzymes with One-month mortality in AMI patients referring to Hajar Hospital of Shahrekord in 2011. Materials and method: For this descriptive analytical study, 107 AMI patients were randomly enrolled. For gathering data a questionnaire was used. Demographic data and test results of cardiac enzymes, EKG, and echocardiography according to the medical profile were registered in the questionnaire. The follow-up continued for 40 days through phone calls and medical profile and the mortality and/or any recurrent myocardial complication was entered into the medical profile. Data analysis was performed by SPSS 11 using chi-square, Spearman correlation coefficient, and t test. Results: The mean age of patients was 60.62±12.58years. Mortality showed a direct association with age and personal history of ischemic heart disease (p<0.05). In addition, one-month mortality was directly associated with troponin, ejection fraction, and the number of segments involved in echocardiography (p<0.05); troponin level in outliving people was less, the mortality among patients with less ejection fraction was higher, and the number of involved segments was higher in the dead compared to the outliving. Conclusion: The findings of this study emphasize the value of echocardiography in determining the prognosis of AMI. Moreover, troponin could have a high prognostic value in addition to its high value in diagnosis.

Abstract: Sensitivity is one of the important indicatives for evaluating the reliability of a medical procedure. Herein, we have evaluated the sensitivity of CT angiography (CTA) in comparison with conventional invasive angiography (CIA) in the diagnosis of significant stenosis. For this purpose we used a 16-multidetector-row scanning machine. In this regard, 8 patients suspected to stenosis were investigated. They patients were undertaken both procedures. The obtained results show, the sensitivity of 87.5 % for patient-base analysis. The findings of this study reveal that CT angiography with 16-slice scanner might be considered as an acceptable technique for rapid triage of patients. The moderate value of sensitivity depicts moderate score for CTA protocol for replacement. It should be noted that the low number of patients results in obtaining results which cannot be used for final decision. and more patients is required to examine the procedure.

Abstract: Objective: The pressures resulting from physical, mental and social fluctuations play a significant role in causing depression and decreasing the happiness in the elderly. The percieved social support and religious beliefs are among some parameters which influence their life satisfaction. Taking this into account, this study intends to examine the effect of social support and religious beliefs on the life satisfaction among the elderly living in Borujen. Methedology: This study which is descriptive-analytical in nature was conducted on 105 of the elderly living in Borujen. Data was gathered by using a questionnaire consisting of 3 variables i.e. social support, religious beliefs and the level of life satisfaction developed based on the following three questionnaires: Canty-Mitchell's Social Support Questionnaire (2000), Golriz and Brahnew's religious beliefs questionnaire and Dinner, Emmons, Larsen and Griffin's questionnaire for life satisfaction. The reliability of the developed questionnaire was found to be 0.83% using Cronbach coefficient α. The gathered data was analyzed using descriptive statistics, Pearson correlation analysis and stepwise multiple regression analysis. Findings: Based on the findings of the study, the mean score for the level of life satisfaction among the elderly living in Borujen was found to be 22.46. There was a statistically significant relationship between the social support and the level of life satisfaction in the elderly (p<0.001). The addition of the religious beliefs variable was accompanied by an increase in the social support and the level of life satisfaction in the elderly living in Borujen (p<0.001). Conclusion: Given the need of the elderly to the social support from their surrounding people, it can be inferred that the social support and religious beliefs play a significant role in their level of life satisfaction promoting their life satisfaction.

Abstract: The Among the responsibilities which mangers are, in most theories and concepts on management, supposed to assume is decision making which is indeed considered as one of the main criteria in confirming their qualifications and/or assigning them to positions. Decision making is the main essence of management process and the heartbeat of the organization. Methods: The sample population consisted of 51 high ranking managers of the public sector and the questionnaire administration was done according to census method. Data analysis was done by SPSS 16 software using descriptive and inferential statistics such as t-test, Mann-Whitney, chi-square, Pearson correlation coefficient, etc. Results: Decision making style of 120 (39.2% of the) participants was based on substantive rationality and that of the rest was based on instrumental rationality. In addition, the results indicated no association between decision making style and age and management history, partial association between decision making style and organizational nature, and strong association between decision making style and academic degree (the participants with higher academic degrees had instrumental decision making  style). Conclusion: Regarding the present study’s results, we offer some recommendations on change of predominant paradigms in managerial environment of public organizations according to Islamic values and special attention to modifying the managers’ decision making style according to organizations’ nature.

Abstract: Background: Up till now, there is still no ideal tumour marker for early diagnosis and effective monitoring, especially for patients who undergo surgical resection of colorectal cancer (CRC). Objective: to evaluate the clinical utility of normal and modified urinary nucleosides as diagnostic biomarkers to be used for the purpose of screening for CRC, in addition to assessment of the correlation between their preoperative levels, tumour size and modified Duke's staging, as well as their role in monitoring of surgery, as compared to CEA, the routinely used serum marker. Subjects and Methods: This study was conducted on 30 patients with CRC (Group I), 30 patients with benign colorectal diseases (Group II) and 30 apparently healthy subjects (Group III). Morning urine and serum samples were collected before surgery and on day 7 postoperative, for the assay of urinary nucleosides (adenosine, cytidine, guanosine, uridine, 1-methyladenosine, 7-methylguanosine and N4-acetylcytidine) by reversed phase high-performance liquid chromatography, and serum CEA by chemiluminescent sequential immunometric assay. Results: The levels of the measured urinary nucleosides in group I were significantly higher than those of group II or group III. Moreover, the elevated levels of the urinary nucleosides significantly decreased after curative resection of CRC. A significant positive correlation was found between the preoperative levels of some nucleosides and the tumour size, as well as the modified Duke's staging of CRC. Conclusion: Urinary nucleosides are satisfactory diagnostic biomarkers of CRC. Moreover, they are apparently of value in the postoperative monitoring of CRC patients.

Abstract: This study was conducted to evaluate immunogenicity and protective efficacy of different inactivated Newcastle disease (ND) vaccines given to 10 days old chicks with or without prebiotic. Both weekly sera for haemagglutination inhibition (HI) test and tissue samples for histopathology were applied while challenge test with virulent field virus were carried out at the end of the 3rd week post vaccination. In this study; 360 1-day old commercial broilers were grouped into 12 equal groups (20 chicks each). Chicken groups were vaccinated by Hitchener B1 vaccine at 5 days of age for brimming followed by subcutaneous (S.C.) injection with inactivated ND vaccines as follow: groups (1& 6); (2& 7);( 3& 8); (4& 9) and (5 &10) were received monovalent inactivated Locally produced ND vaccine ND-SVRI; Volvac® ND-AI; Volvac® ND Conc. KV; Laprovet® as well as Imopest® vaccine; respectively. While groups 11 and 12 kept as positive control prebiotics and negative control groups; respectively. Groups 6, 7, 8, 9 and 10 were treated with commercial prebiotic from day one old. All vaccinated groups showed no clinical signs or mortalities, after challenge with field virulent virus control negative and those received prebiotics showed clinical signs and mortalities of 90% and 80% respectively. HI test result in groups treated with vaccine and prebiotics are high. By the end of 3rd week post vaccination, the highest HI-titer were log2 9 in groups receive Volvac® ND and Imopest® followed by groups receive bivalent Volvac® ND-AI and Laprovet® which was 8.7, finally it was 8.2 for group received ND SVRI. Groups received prebiotics alone and control negative showed titres of 2 and 3 by the end of 3rd week post vaccination; respectively. Vaccinated groups received prebiotics have positive effect on antibody titer for all vaccinated groups. Antibody titer was decreased sharply in all groups at 1 weeks post challenge. Groups receive vaccine without prebiotics was nearly 1 log lower than those received vaccine with prebiotics. Bursal sections of all vaccinated groups showed varied degree of histopathological changes from one vaccine to another as it showed slight lymphoid follicle depletion in groups received monovalent ND-SVRI and monovalent ND Laprovet®, while groups received bivalent Volvac® ND-AI and Volvac® ND Conc. KV showed moderate lymphoid depletion together with hyperactivity of the lymphoid follicle, while group received ND Imopest® showed neutrophilia together with hyper activity of lymphoid follicle that shows even activated germinal center with presence of lymphoblast and mitotic. Bursa of groups received inactivated vaccines and prebiotics represented in as it showed light lymphoid follicle depletion with normal spleen and thymus. After challenge lesion in bursa of all groups showed changes varied from sever bursal depletion to sever bursal depletion with connective tissue formation, spleen showed depletion with congestion of red bulb, there was no pathological changes in thymus. It could be concluded that priming vaccination of chicks with live ND vaccine followed by inactivated Newcastle vaccine produce good immune response protect birds from challenge, moreover the use of prebiotics found to be of value in improving HI titers against Newcastle. The use of prebiotics to improve immune response to used Newcastle vaccines is important.

Abstract: Bovine herpesvirus 1 (BoHV-1) is an important contagious viral pathogen negatively affecting the livestock industry because of respiratory illness and /or abortion. Most of the disease protection programmes in Egypt depend on imported vaccines and unfortunately molecular studies on molecular and phylogenic analysis of viral strains are rare. Such studies are needed to determine which viral strains should be used in vaccine manufacture so as to provide proper protection to susceptible animals in Egypt. The gB, gC, gD and gE glycoproteins of BoHV-1 are the most important because of their functional properties including virus entry into target cells, viral gene expression, DNA replication, and phylogenetic relationships. This is the first report in which glycoproteins of Egyptian BoHV-1.1 virulent strains have been sequenced and compared with U.S. strains, thus increasing our understanding about the genetic relatedness of various strains of BoHV-1 and between bovine alphaherpesviruses (BoHV-1 and BoHV-5). Our results indicate that the Egyptian Abu-Hammad strains are 100% similar to each other and with U.S. Cooper reference strain suggesting that vaccines based on the latter strain are adequate in providing protection to susceptible animals in Egypt.

Abstract: Two local psychrotolerant coloured bacteria, Kocuria polaris MO and Kocuria carniphila MY, which were isolated from Nile river during winter in Kafer El-Shakhe-Egypt. They were investigated for natural pigments production as K. carniphila MY was a yellow isolate and K.polaris MO was an orange one. These natural pigments were extracted using acetone after cultivating both isolates on King’s medium and being incubated at 10°C for 7 days. Low incubation temperatures for both bacterial isolates were found to enhance production of large amount of pigments which was seen to be reduced by increasing temperature till it was completely vanished above 30°C. On the other hand, a pH value of 7-8 was optimum for pigmentation in both strains. Light was found to be suppressive for pigmentation in both isolates where in dark places pigment production was improved rather than in lightened ones. No significant difference was shown on pigmentation after incubating cells once static, and then shaken. Bacterial pigments were then identified by TLC, where it was found that K. carniphila MY contains β-carotene and xanthophylls, while K.polaris MO contains β-carotene and echinenone. Pigments were then separated by column chromatography and it was found that K. carniphila MY contains 0.127 mg/g of β-carotene and 4.073 mg/g xanthophills while K. polaris MO contains 0.308 mg/g of β-carotene and 0.2 mg/g of echinenone. β-carotene, echinenone and xanthophylls were determined spectrophotometrically after separation.

Abstract: Thermogravimetric analysis TGA was carried out to obtain the activation energy of thermal decomposition for Polyvinyl alcohol PVA stabilized by Polyethylene glycol PEG. The effect of addition of PEG, with different concentrations, to PVA was studied. The results indicated that the addition of PEG with 0.015 g/1 g PVA led to a more compact structure of pure PVA which resulted in an improvement in its thermal stability with an increase in the isotropic character of the polymer samples. Samples from the 0.015 g PEG/1 g PVA were irradiated with X-rays in the dose range 10-100 Gy. The variation of onset temperature of decomposition, activation energy of thermal decomposition and refractive index has been investigated. In addition, the transmission of these samples in the wavelength range 370–780 nm, as well as any color changes, was studied. The color intensity ∆E was increased with increasing the X-ray dose indicating that the color difference is largely dependent on the proportions of the red and yellow color components.

Abstract: The endangered medicinal orchid, Dendrobium officinale, has low reproductive capacity in its natural environment and its wild resources are exceedingly scarce. Domestication, including development of rapid propagation methods, is needed urgently to satisfy human demand for its medicinal products. This study developed optimized micropropagation methods for D. officinale by testing the effects of tissue culture media and additives on shoot proliferation and rooting. The optimal proliferation medium for D. officinale was ½ Murashige and Skoog (MS) with 2.0 mg L-1 benzyladenine (BA) + 0.1 mg L-1 naphthaleneacetic acid (NAA) + 100 g L-1 potato extract. A rooting medium composed of ½ MS + 0.2 mg L-1 BA + 1.0 mg L-1 NAA provided 100% rooting. These methods allow reliable mass-production of D. officinale for medicinal purposes.

Abstract: Objective: To compare the incidence of early in-hospital recurrent ischemia and/or reinfarction (fatal or nonfatal) in patients receiving thrombolytic therapy for ST segment myocardial infarction (STEMI) and those who did not receive thrombolysis, and to assess the clinical risk factors for reischemia and /or reinfarction in both groups. Methods: 285 consecutive patients presenting with STEMI were enrolled, and divided into two groups, whether refused primary percutaneous coronary intervention (PCI) and being eligible candidates for thrombolytic therapy in the first group, and those who were not the candidate to thrombolytic therapy in the second group. Eighteen clinical variables were assessed to identify the predictors of early in-hospital (pre-discharge) reischemia and/or reinfarction in both groups. Results: Thrombolytic therapy was given to 159 patients, while 126 (44.2%) patients were treated conservatively. Re-ischemia was diagnosed in 30 patients (19 in thrombolytic versus 11 in non thrombolytic candidates), while reinfarction was diagnosed in twelve patients (8 in thrombolytic versus 4 in non thrombolytic candidates). Five of the reinfarction events were fatal. The episodes occurred within 4.71±3.6 days in thrombolytic cases versus 5.85±2.5 days in the non thrombolytic cases (P=0.263). Anti-thrombotic and anti-ischemic medications were used equally in both groups (P=0.002 and P>0.05 respectively). However there was a significant higher rate of Beta-blockers usage among thrombolytic candidates than non thrombolytic candidates (P=0.002). Thrombolytic candidates were relatively younger than non thrombolytic candidates (P=0.001). Conclusion: Despite of conventional medical treatment including thrombolytic, anti-thrombotic and anti-ischemic therapy some survivors of MI were subjected to re-ischemia and/or reinfarction events during early in-hospital follow up. The incidence is slightly higher in patients who received thrombolytic therapy compared to those who did not, but statistically not significant.

Abstract: Usage of multiple cameras has become quite popular in various domains. The final output is usually displayed to the human who will watch and make a decision. When the number of cameras increases it is difficult to handle the outputs by single person. To overcome this issue, smart cameras and intelligent control center systems are created. This work is about handling video inputs from multiple cameras, by prioritizing the scene context. In this paper we suggest our architecture for efficiently building priority based multimedia streaming control system.

Abstract: It is necessary to select a problem from dynamic problems of viscoelasticity about fluctuation of the viscoelastic systems which decisions are consolidated to Voltaire's integro-differential equation of the II type. The solution of this equation requires a problem of an analytical type of a kernel, or ths equation solves with various numerical methods. In this paper the approximate solution of this equation for any kernels at small viscosity is proposed. The decision in the form of a row is received, the original of which first member is the solution of this equation received by a known method averaging, and the accounting of the subsequent members of a row improves objective accuracy. Influence of the subsequent members of a row on the decision is calculated for Rzhanitsin's kernel and shown that it increases at increase in frequency.

Abstract: People are beginning to realize the importance of knowledge and its great usefulness as a tool for competitive advantage. “Knowledge Management” envisages the creation of value from the indefinable assets of an organization. It demonstrates the best way to weigh knowledge within the organization with its employees and to all external and internal stakeholders. This paper envisages the investigation of “Knowledge Management Strategies Balanced System” for the development of an organization’s overall policy approach and management (Serenko, et al., 2008). The paper explores “Strategic Knowledge Management (SKM) using a composite tactical approach while concentrating on Knowledge Management comparisons between Saudi Arabia, Pakistan, India, Bangladesh and China. Because of the different economic situations and dynamics in these five countries it becomes quite difficult to properly analyse knowledge sharing and therefore the main focus of the paper is to do comparative analysis of knowledge management practices in these countries. The paper is not aimed to produce a theory or to develop any model.

Abstract: The effects of exposing commercial feeds for European sea bass (Dicentrarchus labrax) were examined to lower prices diet. Trash fish used as aqua feed were submitted to six feeding schedules in net pen cultivation (40 fish/net pen). Each treatment had two replicate net pen. The present study was performed to investigate the influence of individual fed local trash fish (8.6% of body weight) or dry pellet diet (2.2% of body weight) with four feeding schedules (Fs) as fed European sea bass (a range initial body weight from 19.57 to 24.85g) for 140 days. Fs1: 1.1% of body weight (BW) dry pellet at 9.00am and 4.3% of BW. Local trash fish at 14.00pm; Fs2: one day 2.2% of BW. Dry pellet diet consecutive another day 8.6% of BW. Local trash fish; Fs3: one day 2.2% of BW Consecutive two days 8.6% of BW Local trash fish; Fs4: two days 2.2% of BW. Dry pellet diet consecutive one day 8.6% of BW local trash fish. Growth performance, survival rate, proximate analysis of dorsal musculature and some somatic parameters of European sea bass were measured to assess four feeding schedules compared to fish fed only local trash fish or dry pellet diet. The improved of weight gain percentage, geometric mean were obtained in fish fed with feeding schedule No. 4(2 day fed dry pellet diet with one day feed local trash fish) compared to other feeding schedules. The survival rate of D. labrax feeding schedule No. 4were higher compared to other fish feeding schedule 1, 2, 3. Proximate analysis of dorsal musculature of different feeding schedules showed significantly (P < 0.05) concentrations of lipid compared to fish fed only local trash fish as dry pellet diet. Small, round and transparent oocytes with a central nucleus were observed in histological sections of ovaries. Though, testes based on microscopic observation were distinguished for male D.labrax and spermatogonia and primary spermatocytes were the dominant cells of this stage. The results of this study revealed that the overlap between local trash fish with dry pellet diet under feeding schedule No.4, could be used in fed European sea bass (D. labrax) to give better growth performance.

Abstract: One of the major problems facing aquaculture is the raising prices of commercial feeds for European sea bass (Dicentrarchus labrax) and environmental risk with using inadequate supply of ingredient diets. An 20- week feeding experiment was conducted on D.labrax (initial body weight, BW, 22.25±0.59g) to determine higher benefit of dietary content from local trash fish (feeding rate 8.6% of body weight) or dietary content from dry pellet (feeding rate 2.2% of BW.) individually and or with overlap in four feeding schedules (Fs): Fs1: 1.1% of body weight (BW) dry pellet at 9.00am and 4.3% of BW. local trash fish at 14.00pm; Fs2: one day 2.2% of BW. Dry pellet diet consecutive another day 8.6% of BW. Local trash fish; Fs3: one day 2.2% of BW. Consecutive two days 8.6% of BW. local trash fish; Fs4: two days 2.2% of BW. Fish (in experimental diets) were maintained outdoor (40 fish / net pen culture) under natural condition of temperature and photoperiod with duplicate per treatment. The performance of feeding schedule compared with a dry pellet diet or local trash fish fed European sea bass was examined. Feed conversion ratio, feed conversion efficiency and protein efficiency ratio were better with fish feeding schedule 4, and fish was feed on only dry pellet diet comparison with feeding schedule (1.2.3). Protein, lipid and energy retention of D. labrax had significantly higher (P< 0.05) compared to fish fed only local trash fish.

Abstract: In the northern part of Pakistan, thousands of landslides were triggered during the 2005 Kashmir earthquake. On 24 March 2014, the  Karli landslide, located in district Hattian, about 65 km southeast of capital city of Muzaffarabad, Pakistan was reactivated due to heavy rain fall. Simultaneously, another slide adjacent to the main slide was triggered that transformed rapidly into earth flow. In order to investigate the Karli landslides, field investigations were carried out two weeks after the reactivation of Karli landslide. In addition, SPOT and Google imageries were used to delineate the affected area. DEM was used to study the topographic characteristics of the area.  The landslide affected area measuring about 1000 m long and 800 m wide damaged about 156 houses and displaced 900 inhabitants. In addition, on 24 March 2014 earth flow destroyed 3 houses completely and many others are under potential threats. On the basis of field observation and satellite data it is inferred that the Karli landslide was outcome of breach out of Karli lake in February 2010. The landslide movement initiated after falling down of water level of the Karli lake. The landslide hazard assessment indicates that the affected area is under continuous threat of landslide due to the effects of drawdown of Karli lake. Therefore, the inhabitants of the Karali area are under potential risk and need to be relocated to the safer places.

Abstract: Information is probably the most valuable asset of many people and information systems. However, some data cannot be memorized easily. As a result, these data and information should be stored in a special place to recall later. Several technical methods and process for keeping data was designed by technology improvement such as database which is a data collection in a special arrangement and structure. Data protection is not only essentially important for some users like business users but also for nonprofessional’s computer users. Since some events such as natural disaster and human behavior causing harms and much more cost, evaluating possible threats and susceptibility of system which is employed to protect the data should be taken into account. Therefore, securing data by using some new methods is a significant subject. Many studies prove that the “insider threat” is the most dangerous information security threat in advanced technological organization. It can be inferred that workers employ their individual privileges to do actions on the basis of their information and have knowledge of some susceptibility of the system might be an insider and perform some attack. As a result, employee‘s attack has significant hazardous and critical effects. In this paper a practical approach in prevention and detection of such malicious attack is introduced.

Abstract: Pistacia Lentiscus and Boswellia Carterii (Raw), which are widespread in the popular culture and sold by spice shops for incensing houses, are used for fighting House Dust Mites (HDM), for the purpose of identifying their impact on minimizing the prevalence of HDMs. The field experiment was conducted in thirty rooms (separate fifteen rooms for incensing by using P. lentiscus, and the remaining fifteen rooms for incensing by B. Carterii), through using traditional incense burner, and placing the tested substance in clay crucible on the flame for quarter hour on daily basis during the first week, 30 minutes during the second week, 45 minutes during the third week, and 60 minutes during the fourth week. Surveyed rooms were prepared under similar conditions with regard to living standard and type of furniture containing ceramics covered with thick carpets, windows were tightly closed and air was denied access throughout the study period (one month), except for once a week (the seventh day of each week after taking the samples), then windows were tightly closed again, and daily incensing for a certain period for each tightly closed room. next, collection process was made by mean of using one Vacuum cleaner, and then the mortalities were counted at a rate of fifty grams of dust collected from each separate room on a case-by-case basis, and then average sample score was set. Findings showed the effectiveness of used substancesin relatively limiting the prevalence of HDM. Findings also revealed an increase in mortalities rate in the rooms incensed byP. Lentiscusas compared to rooms incensed by B. Carterii. Dermatophagoides pteronyssinus, Dermatophagoides, Suedasia nesbetii, Blomia fremani and very low numbers of Dermatophagoides pteronyssinus, Dermatophagoides farinae, Clyetus malcinyiss, and Tyrophagous putrescentiae were identified.

Abstract: The optical emission spectrum and the spatial distribution of optical emission lines and bands of N2, Ar and He gases are measured for rf and dc glow discharges. A comparative investigation of the plasma characteristics between dc and rf power modes is presented using the emission lines of the different gases. Optical emission spectra from nitrogen discharges in the wavelength range from 350 to 750 nm are recorded. The second positive system of N2(C–B) and the first negative system of  QUOTE   (B–X) spectra are observed. Various emission lines of argon ions are commonly observed from the argon discharges regardless of the rf power and/or discharge current. The main emission atomic lines of He I glow discharge plasma are obtained for both discharge modes, while the ionized He II line at 468.6 nm is recorded for rf discharge and absent in dc glow discharge. The electron temperature Te is determined from the optical emission spectra by the line-to-line method. Te decreases with increases the gas pressure and increases with increases the rf input power.

Abstract: The present article is a comparative study on the mineralogical as well as the geochemical characters in Burullus lake sediments and Bardawil lake sediments, Mediterranean sea coast, Egypt. Mineralogically, the heavy mineral assemblage recorded from lake Burullus samples are particularly enriched with unstable minerals (pyroxenes and amphiboles and epidotes) accompanied by lower contents of ultrastableminerals (zircon, tourmaline and rutile), reflecting a provenance dominated by basic igneous rocks. For Lake Bardawil samples, the sediments are characterized by substantially higher contents of ultrastable minerals (zircon, tourmaline and rutile), beside a subordinate component of pyroxenes and amphiboles, minerals of metamorphic affinity such as staurolite and garnet constitute a recognizable part of the total non- opaque fraction. The clay mineral suit detected in lake Burullus samples is uniform in most of the investigated area suggesting constancy of the source area, it is dominated by smectite with subordinate amount of kaolinite and lesser illite contents. The recorded clay minerals in Bardawil samples are a mixture of smectite, kaolinte and illite with variable contents from one location to another reflecting variability in source rocks. Smectite tends to be more abundant in the western samples while illite increases eastwards, however, kaolinite constitutes a noticeable part in most of the investigated samples. The recorded heavy mineral assemblage, the identified clay mineral suit as well as the results obtained from the geochemical data, revealed that, the investigated lake Burullus sediments were derived mainly from one source which is dominated by mafic components. They are most probably derived and related to the Quaternary Nile sediments. On the other hand, the Bardawil lake sediments reflect derivation from more than one source, they originated mainly from reworked sediments especially Nubian sand stone, high rank metamorphic and basic igneous rocks derived from the neighboring sand dunes. Fluvial Niolitic sediments must be considered also as an important additional source.

Abstract: Background: The role of decompressive craniectomy in the management of severe traumatic brain injury is a subject of debate in the present era. Increased intracranial pressure (ICP) can cause brain ischemia and compromised brain oxygen after severe traumatic brain injury (TBI). Decompressive craniectomy (DC) is applied to treat post-traumatic intracranial hypertension (IC H). The purpose of this study is to prove the efficacy of early decompressive craniectomy (DC) in the treatment of elevated ICP and good clinical outcome after severe head injury. Methods: A retrospective study was conducted of 21 patients who underwent cranial decompression after severe head injury. Baseline demographics, neurological examination results, and underlying pathology were reviewed. Clinical outcome was assessed by length of intensive care unit stay, length of hospital stay, and survival at discharge. Control of intracranial hypertension was assessed by intracranial pressure (ICP) monitoring and an ICP therapeutic intensity index. Radiographic outcomes were assessed by comparing preoperative and postoperative CT scans for: 1) postoperative volume of cerebral expansion and brain edema; 2) presence of uncal herniation; 3) intracerebral hemorrhage; 4) Subdural collections, and 5) brain ischemia. The patient’s age, six, trauma etiology, GCS and focal neu­rological deficit at admittance, and associated other injuries were reviewed as well. According to GCS results, the patients were grouped as severe TBI (GCS=3–8), moderate TBI (GCS=9–13) or mild TBI (GCS=14 and 15). Only Severe TBI group are reviewed in this study while other groups are excluded. Results: DC was performed on average 2- 12 hrs after admission. DC was found to immediately reduce ICP about 6-11 mm Hg from 20, 27mmhg to 14-16mmHg). TIL, continued to improve within the postsurgical monitoring period. The duration and severity of CIB were significantly reduced as an effect of DC. The overall mortality rate in the patients was lower than predicted at the time of admission. Conclusion: These results suggest that a DC for increased ICP can reduce the CIB of the brain after severe TBI. We suggest that DC be considered early in a patient's clinical course, particularly when the TIL and ICP are increased. Also large decompressive craniectomy (frontotemproparietal) combined with enlargement of the dura by duraplasty seems to have the most favorable results beside it decrease the risk of several secondary surgical complications.

Abstract: It is well known that foodborne infections can be transmitted to humans via vegetable consumption. The study reported here aimed to determine the prevalence of parasitic contamination on raw vegetables sourced from the mountainous southwestern region of the Kingdom of Saudi Arabia. The vegetables examined in this work included lettuce, green onions, cucumbers, carrots, spinach, tomatoes, parsley, ginger, radish and arugula. For each vegetable type, 20 samples were collected from the four markets included in the study, resulting in 800 samples used in subsequent analysis. More specifically, 200 samples were sourced from each main market of the main four cities located on the Sarawat mountain range of the Kingdom of Saudi Arabia, namely Altaif, Albaha, Baljurish and Abha. These samples were analyzed by a concentration method and examined by light microscopy. Helminth ova were detected in the examined vegetables. While the lowest contamination with helminth ova was detected in cucumbers, tomatoes and green onions, the highest contamination was observed in radishes, parsley, carrots, spinach and ginger. Moreover, the highest helminth ova contamination was seen in samples from Albaha (n = 38), followed by Baljurish (n = 30), Altaif (n = 25) and Abha (n = 22). Trichuris trichiura and Trichostrongylus were the most commonly detected infectious agents in the vegetables, while ­Hemenolepis nana was the least prevalent. The contamination of vegetables with infective ova emphasizes the need for adequate preventative measures that can assist in avoiding the transmission of diseases.

Abstract: Actuality of work associated with fine-grained structure obtaining in aluminum alloys for production goods by sheet stamping methods. The problem of establishing the influence of the grain structure dispersion on the mechanical and technological properties of high-alloyed aluminum alloys blanks is solved in the article. Plastic deformation and low-temperature annealing of Al-10% Mg and Al-5% Cu - 2% Mg (2024) flat samples are carried out. Their mechanical properties (tensile strength, yield strength, relative elongation) were identified by static uniaxial tension. The graphs of dependence of true tension and deformations are constructed. Evaluation of the grain structure dispersion was carried out by the coherent diffraction areas changing on the basis of X-ray diffraction analysis results. The graphs of dependence of mechanical and technological properties of the coherent diffraction areas size in these alloys are constructed. Microstructures of samples in the annealed condition were considered. The assessment of technological effectiveness of alloys Al-10% Mg and 2024 in operations of sheet stamping by stamping coefficient estimation is carried out. The sizes of crystallites for obtaining favorable strength, plasticity and technological effectiveness of alloys in operations of sheet stamping are revealed. It was established that grain size obtaining less than 1.8 microns in alloy 2024 and 4.3 microns in the alloy Al-10% Mg while cold rolling and interoperational annealing is impractical for subsequent stamping operations

Abstract: Hepatitis B virus (HBV) infection often leads to chronic hepatitis, cirrhosis and hepatocellular carcinoma. Human cytosolic glutathione-S-transferases (GSTs) include seven distinct classes, namely, Alpha (A), Mu (M), Pi (P), Sigma, Zeta, Omega and Theta (T). In this study, the genotypes of GSTs especially GSTT1, M1, P1 and A1 were determined in the control (C) and the different groups of patients with HBV to investigate the role of host genetic factors in HBV infection. GST activity and liver profile tests were determined. HBV groups were classified according to clinical history, serological tests and histological analysis into normal carriers (N), acute (A), chronic (CH), cirrhosis (CI) and hepatocellular carcinoma (HCC). The results showed that wild GSTM1/GSTT1 genotype, GSTP1 isoleucine / isoleucine and GSTA1 cytosine cytosine (BB) were decreased in N, A, CH, CI and HCC groups compared to the C group. However The genotypes null GSTT1, null GSTM1, double null GSTM1/GSTT1 and GSTP1 valine/valine, GSTP1 valine / isoleucine genotypes and GSTA1 thymine thymine (AA) and GSTA1 cytosine thymine (AB) were increased in all studied groups compared to the C group. This indicates that GSTs genetic polymorphism may be considered as an accurate biomarker for determining and predicting the progression of HBV infection.

Abstract: The Government of Thailand has encouraged the planting of teak for replacement of existing natural forest wood, where recently teak woods have been grown more than ten million trees and in the industrial cutting. Apparently, teak wood has the high value with special features than other types, which has been used the same value as other woods. Wood carving is one of the major crafts of the northern of Thailand, which is also accepted as creative economy. It is also the National policy for creative economy, which is the highest value added in supply chain of teak wood. The intelligent tutoring systems (ITS) of teak wood is the research proposal for maximum value added, which is developed from three parts in Thailand, where they are from the expert knowledge of wood carving, carving instructor and succeed students, which is used Nonaka’s Ba ( Physical Ba , Virtual Ba) for environmental studying.

Abstract: The author provides an analysis of approaches to the problems of gender and the posthuman in Russian philosophical and sociological literature. According to the author, the main feature of the appearance of this type of research is connected both with fundamental changes in Russian society and the development of humanitarian sciences, that’s why it’s necessary to study this problematic field from social and philosophical points of view. The article offers to distinguish five stages of formation and development of this problematic field in Russia. Although such a division is rather relative, it permits to understand better the originality of problems which have been decided in different periods of the development of Russian gender and posthuman research. It’s proved the idea that the posthuman concept has emerged in Russian science in relation with the final stage of gender research which is closely connected with the entry of Russian society into the epoch of extensive informatization and globalization. The article examines the ideas of Russian cosmism popular among Russian representatives of hard and natural sciences, doctors, IT specialists who support and widespread the posthuman ideas in the country. According to the author, one of the main dangers of the modern society is losing personal originality by man, disappearing distinctions between male and female. Nanotechnologies are analyzed as a bright example of this statement. It becomes clear that problems of gender are neglected with such an approach and they are paid less and less attention. The posthuman ideas are directed to existence beyond the humanism, i.e. human body turns out to be beyond personality and its gender. So, the article offers the concept of creating something like a “post-humanistic” gender.

Abstract: The purpose of this study was to examine the relationship between parent-child relationship and the adolescent’s aggression among Iranian high schools students in Tehran, Iran. There is a transformation in the parent-child relationship as child approaches adolescence due to biological, cognitive and emotional changes. The present study was carried out among Iranian students. Number of respondents in the present study includes 200 (50%) males and 200 (50%) females from 20 high schools in Tehran, Iran. Respondents were between the ages of 16 to 18 years. Pearson correlation between subscales of aggression and between parent-child relationship was done and according results the strength of correlation between mother-child relation and aggression is moderate but more than Father–childe relation. This means that respondents of low Father and Mother Relation have higher aggressive tendencies.

Abstract: The Natural radioactivity concentrations of 226Ra, 232Th, and 40K were determined in 22different brands o f commonly bottled drinking water samples collected from local market of Saudi Arabia (Jeddah city), measured using high-resolution HPGe detector system. The average measured activity concentrations of the nuclides 226Ra, 232Th and 40K are found to be 0.77, 1.3 and 11.1 Bq l-1, respectively. The total average annual effective doses due to all three natural radionuclides for different age groups of Infants (1–2 y), children (2-7y, 7–12 y) and adults (˃ 17 y) were estimated to be 0.487, 0.516, 0.629, 0.865 and 0.43 µSv y-1, respectively.The measured activity concentrations have been compared with similar studies from different locations. it was observed that measured activity concentrations of natural radionuclides in the bottled drinking water were lower than most of these values. Also,the effective doses resulting from the consumption of the bottled drinking water were estimated for all three age groups and were found below the World Health Organisation (WHO 2008) recommended limit of 0.1 mSv y-1 as well as the average radiation dose of 0.29 mSv y-1 received per head worldwide due to ingestion of natural radionuclides assessed by UNSCEAR (2000). The resulting data may serve as base-line levels of activity concentration in drinking waters in Saudi Arabia.

Abstract: Aging is a significant health issue because of the association of low testosterone levels with a lot of diseases and a decrease in life quality and expectancy. The aim of this study was to weigh the benefits versus risks of testosterone replacement therapy (TRT) in old men. The current work was a prospective controlled study that included 54 aged men with ages >50 complaining of weak erection. Cases were recruited from Andrology Outpatient Clinic, Kasr El-Aini Hospital, College of Medicine, Cairo University. All cases were treated by testosterone enanthate, 250 mg every 3 weeks as intramuscular (IM) injection for 6 months. Free and total testosterone (T), PSA, LH, E2, lipid profile, liver function tests and CBC were done before and after TRT. Cases were asked to fill a questionnaire for quality of life and Massachusetts Male Aging Study Sexual Activity Questionnaire. The study revealed that TRT had no detectable risks of cancer prostate as evidenced by absence of significant changes of PSA levels after TRT (p>0.05) in addition to the finding of digital rectal examination. Also, no significant changes in lipid profile or hepatic functions as evidenced by the insignificant changes of mean values of parameters of lipid profile and liver function tests after TRT (p>0.05). No risks for polycythemia as evidenced by insignificant changes in hemoglobin, hematocrite and RBCs count (p>0.05). No significant changes in platelets counts (p>0.05), and thus no fears of thromboembolic sequelae related to changes in platelets counts. There was improvement in both physical and cognitive problems in 33% & 22% of cases with significant differences between scoring grades before and after TRT (p<0.05). There was no detectable improvement in affective problems of this age. Highly significant improvement in all sexual satisfaction parameters and in getting and keeping erection (p0.001) was recorded with a percentage of improved cases ranged from 23% to 41%. Little improvement was shown in the frequency of sexual activity (4% of cases), getting and keeping erection (7%). No significant difference in free & total T levels between cases & control which means that other etiological factors with T are responsible for occurrence of andropause. In conclusion, IM TRT appeared to be associated with some beneficial outcomes on physical and cognitive functions in old men and it improved most sexual satisfaction parameters and some sexual performance like getting and keeping erection. At the same time, it has no detectable risks on lipid profile, liver function tests or hematological parameters. No cases had developed polycythemia or cancer prostate which are the most debated conditions as regards this therapy.

Abstract: To investigate improved root organogenesis and micropropagation in Chrysanthemum morifolium Ramat cv. Hwiparam, we established an efficient protocol using different media and concentrations. Stem explants were cultured on 3 full strength basal MS (Murashige and Skoog 1962), SH (Schenk & Hildebrandt 1976) and B5 (Gamborg et., al 1972) medium. Then, the best medium for root regeneration was investigated at 5 different concentrations (1/4, 1/2. 1, and 2 strength). The best type of medium for root regeneration and growth was SH medium). The results showed that half strength of SH (1/2SH) is the best condition for the number of root per explant (4.3) and root length (31.4 mm).

Abstract: In the last decade, ski tourism, the development of which is supported at the state level, became the most popular and prestigious type of recreation for Russian in winter.   One of the main localization area of ski centres and mountain ski resorts (MSR) in Russia is the Krasnodar region, which is characterized by its unique natural and climatic resources. This study focuses on the identification of current trends in regional climate according to the state network of meteorological stations with the aim of using this information to build strategies for adaptation of MSR activities to the negative effects of adverse weather and climate events.  Different variants of weather anomalies and modern engineering technology that allow significantly reducing the risks and increasing the cost-effectiveness and sustainability of the MSR were taken into consideration. It is shown that one of the objects of the Olympic heritage of the XXII Olympic Winter Games "Sochi-2014" — the ski centre "Krasnaya Polyana" — is not only a new  infrastructure that conforms to international standards but also modern engineering technology that allow to significantly reduce the risk of abnormal weather. There are given the examples of the cost of adaptation measures to ensure the quality of the snow cover of the ski slopes.

Abstract: Development of new high element aluminium alloys requires of solving features related to the modes of their thermal hardening. In the present work the quenching temperature interval choice of alloy with a high content of magnesium Al-10% Mg is determined. For this purpose, water quenching of extruded bars from alloy was carried from the temperatures leying in the region of the maximum solubility of magnesium in aluminum. The change of Brinell, Rockwell hardness, tensile strength, yield strength, elongation, toughness of alloy samples, cut at an angle of 0 and 90 ° to the axis of compression were found. The analysis of the microstructure using optical metallographic microscope at a magnification of 500 was worked out. It is shown that the tensile strength, elongation, toughness, hardness decreases, yield stress of the samples cut in the longitudinal and transverse direction rise with increasing quenching temperature. The temperature of quenching is set, providing a combination of high strength and toughness properties. The results obtained are discussed from the perspective of the completeness of dissolution of dispersed intermetallic phases. Results can be used during editing operations and wrought and semi-finished products stamping of aluminum alloy with a high content of magnesium.

Abstract: Carpal tunnel syndrome (CTS) and diabetic polyneuropathy (DPN) frequently occur concomitantly. Diagnosis of CTS in patients with DPN is important; however, it can be quite challenging in these cases. Aim of the work: was to study the value of second lumbrical- interosseous latency difference (2L-INT) latency difference in the diagnosis of CTS in type 2 DM patients with DPN. Patients and Methods: This study included 30 patients (60 hands) with type 2 DM. Patients were classified into mild, moderate and severe DPN. Patients were assessed for symptoms and signs of CTS. Electrophysiological evaluation for CTS included the latency difference between the median and ulnar sensory response to the ring finger (DM-DU SLD), latency difference between the median and ulnar motor response (DM-DU MLD) together with the 2L-INT latency difference. Results: In this study 20(33%) hands had clinical manifestations of CTS, while 40 (67%) hands had no clinical manifestations suggestive of CTS. There was a highly significant difference (p<0.01) as regards the 2L-INT latency difference; and a statistically non-significant difference between the two groups (p>0.05) as regards the DM-DU SLD, or DM-DU MLD.2L-INT latency difference was elicited in all the studied hands (100%), as compared to DM-DU MLD elicited in (96.7 %) of hands and DM-DU SLD elicited in (85%)of hands. 2L-INT latency difference had the highest specificity (50%) and accuracy (60%). 2L-INT latency difference had 100% sensitivity among patients with moderate and severe DPN as compared to 66.7% sensitivity in mild DPN patients. It was found to have 71.4% accuracy among patients with mild DPN as compared to 33.3% and 40% accuracy among patients with moderate and severe DPN respectively. Conclusion: 2L-INTlatency difference is an easy, and accurate method for the diagnosis of CTS in type 2 DM patients with DPN especially those with severe DPN. We recommend its corporation in their electrodiagnostic workup; whether they complain of clinical manifestations of CTS or not.

Abstract: The effect of adding different levels of dried grape pomace as a source of antioxidants and fiber at level 1.0% to 5.0% on physiochemical and sensory properties of yoghurt products. The physiochemical properties of yoghurt samples include pH, titratable acidity, syneresis, viscosity, dietary fiber, total phenolic content, antioxidant activity and sensory properties were determined during storage for21 days at 4 C. Increasing the ratios of dried grape pomace had no effect on yoghurt pH values and acidity. During storage periods, the pH values were decreased gradually and increased gradually in acidity in all treatments throughout storage period of 21 days. Dried grape pomace addition up to 2.0 % did not affect the synersis value, but the synersis value decreased, when 4.0 to 5.0 % dried grape pomace was added to the samples. Yogurt prepared with 1.0 and 2.0% dried grape pomace had similar textural properties (hardness, gumminess, adhesiveness, cohesiveness, and springiness) as control yogurts. Fortifying yogurt with 3.0, 4.0 and 5.0% dried grape pomace had significant effect on the textural properties. Hardness, gumminess, and springiness increased and adhesiveness and cohesiveness decreased significantly. The dietary fiber content of yoghurt increased with increased of dried grape pomace in the yoghurt samples. Total phenolic content increased along with increased dried grape pomace concentration in the product, 75, 102,132,168 and 190 mg GAE/100g yoghurt with 1%, 2%, 3%, 4% and 5% dried grape pomace, respectively. Yoghurt prepared with 5% dried grape pomace sample received the highest RSA of 84.72 mg AAE/100g yoghurt initially. Yoghurt fortified with up to 3% dried grape pomace DGP had similar appearance, flavor, texture, consistency, and overall acceptance ratings as control yoghurt. Increasing dried grape pomace fortification level to 4.0% and 5% decreased appearance, flavor, texture, consistency and overall acceptance ratings significantly compared with control yoghurt.

Abstract: The oxidation stability of local base stock, delivered from Co-operative Petroleum Company, in the presence of two prepared Rhodanine derivatives, namely 5-(4-butoxybenzylidene)-2-thioxo-4-oxo-1,3-thiazolidine, (I) and 5-(4-decyloxy-benzylidene) -2-thioxo-4-oxo-1,3-thiazolidine, (II), was studied. The structure of the prepared compounds were elucidated using the traditional tools analyses including elemental analysis, I.R., 1H-NMR and electron ionization mass spectroscopy (EI-MS). The oxidation reaction was tested using the change in total acid number (TAN) and viscosity. The data showed that compound (II) is more efficient than compound (I). The quantum chemical parameters such as the highest occupied molecular orbital (HOMO), the lowest unoccupied molecular orbital (LUMO) energy levels, the energy gap (EHOMO-ELUMO) and the dipole moment were calculated. The quantum chemical calculations were on the same line with the experimental results.

Abstract: Phenol and its derivatives are one of the largest groups of environmental pollutants. Intensive efforts to screen species with high-degradation activity are needed to study their capabilities of degrading phenol and phenolic derivatives. Six different halophilic fungi were isolated from sediments along Suez Gulf and mangrove sediments in Red Sea coasts, Egypt, All tested fungal isolates exhibited the ability to grow and degrade phenol and phenolic derivatives as sole carbon source, these fungal isolates belonging to three genera (Aspergillus, Pencillium and Fusarium). The most potent isolate identified as F. flavipes exhibited the highest efficiency to phenol degradation. It could consume 1000 mgl-1 in 96 hours only, with degradation rate 10.42 mgl-1h-1, reached to 1500 mgl-1 phenol within 72 hours (degradation rate, 20.83 mgl-1h-1) after acclimation process. F. flavipes was also capable of degrading, m-cresol (9.26 mgl-1h-1), o-cresol (8.33 mgl-1h-1), 4-chlorophenol (4.56 mgl-1h-1) and 4-bromophenol (5.20 mgl-1h-1). F. flavipes exhibited optimum temperature for growth on phenol at 30°C. The initial pH of the medium that gave the highest rate of phenol degradation was pH 6. Supplementing the medium with yeast extract and glucose stimulated the degradation, especially at concentration 0.2 and 0.2%, respectively. The best nitrogen source was ammonium sulphate which yield highest rate of degradation (35.9 mgl-1h-1). Optimum concentration of sodium chloride was 6% (rate of phenol degradation, 41.67 mgl-1h-1) and its omission reduced the rate of degradation. Also, the presences of metal ions such as Cr2+, Cd2+ and Zn2+ at relatively high concentration (20 mg-1) slightly reduce the efficiency of phenol degradation while the lower concentration of Pb2+ and Hg2+ highly reduce rate of degradation. The F. flavipes showed a high tolerance and degradation capacity of phenol, it was able to register growth in the presence of 2000 mgl-1 phenol.

Abstract: This investigation was carried out during 2012 and 2013 seasons on Dendranthema grandiflorum, Ram. grown in 25 cm diameter pots at a commercial nursery in Damanhour City, El-Beheira Governorate, Egypt. The aim of this work was to study the effect of different levels of diphenylamine at rates of (zero, 150, and 200 ppm) and ascorbic acid at rates of (zero, 150, and 250 ppm) on the vegetative growth, flowering and chemical constituents of Dendranthema grandiflorum, Ram. From the obtained results it was concluded that treating chrysanthemum plants with diphenylamine at 150ppm and ascorbic acid at 250ppm improve the vegetative growth, flowering characteristics and the contents of chlorophyll "A" and "B", total carotenoids, total soluble sugars and total free amino acids in the leaves of chrysanthemum plants.

Abstract: This article presents the results of research for the expert and methodical centre of assessment and certification of qualifications of specialists in the nuclear industry, which was established on the basis of the National Nuclear Innovation Consortium. A series of new professional standards for the nuclear industry has shown that the value of social and personal competence steadily increases with the skill level of employees. The objectives of the study were to identify latent personality factors that have a significant impact on the performance of various types of management activities and to create a model for assessing the socio-personal competence of managers of the nuclear industry. The study was conducted among a large sample of undergraduate MEPhI students specialising in training management, economics and business informatics. On the one hand, students have well-formed competence in team management, teamwork and conflict management, on the other they are taught to work in the nuclear industry and responsibly assess the technological and environmental risks which are specific to nuclear energy.
