Abstract: Advancements in technology have resulted in more work pressures, thereby affecting the stress levels of the employees to a much larger extent. This has given rise to the novel concept of work life balance which simply denotes a balance to be accomplished between work and life domain of employees. As such researchers have felt a need to create and study a balance between work pressures and ordinary lives. The concept calls for a budding relationship between variables like satisfaction, productivity and health. The paper aims to highlight the role of ICT on the quality of work-life balance. While deliberating on the concept it has come to the fore that ICT have a far reaching impact on work life balance. Studies indicate that due to technological interventions employees are bound to be more productive, but have more stress levels as well. Technological innovations like telecommuting, flexitimes and work from anywhere have revolutionized the work quality and productivity but at the same time have intermingled with the family life.

Abstract: Breast cancer detection with microwave techniques had been of significant interest for the last two decades, which showed increasing theoretical and practical related research works. This necessity needed to mimic the breast tissues with a phantom. This should be nontoxic, cheap, available, and easy to make. Not only, but also it has stable dielectric properties with time able to simulate real breast. Following earlier successful works, local phantom was produced with similar contents but with the available materials. This local phantom model the different types of tissues (fat, gland, tumor, and skin). It accurately simulates the dielectric properties (conductivity, permittivity, permeability) while providing good contrast of conductivity. This phantom was tested in National Research Centre using a TEM Horn antenna, Vector Network analyzer (VNA). To verify that our phantom simulates normal and abnormal breast tissues, it was illuminated with UWB microwave pulse generated by the antenna with a frequency of 3 GHz to 10 GHz and the collected backscattered signals were analyzed and simulated using microwave imaging algorithms to identify the presence and localization of the tumors. A good relationship between permittivity and the conductivity is obtained by using the improved Debye model. MATLAB and Excel software were used in our results. We have been satisfying our results validity by comparing it with earlier scientific research paper.

Abstract: Background: Motivation-hygiene theory is also known as Herzberg’s two-factor theory or Herzberg’s dual-factor theory (1959). The main concept of this theory is the difference between motivation factors and hygiene factors. These two factors that have an effect on job satisfaction are divided into two sets of categories. Hygiene factors are considered less important to job satisfaction than motivation factors. Hygiene factors are related to ‘the need to avoid unpleasantness’. Motivation factors lead to job satisfaction because of ‘the need of the individual for self-growth and self-actualisation’. This theory is one of the most commonly used theories in job satisfaction research (Dion, 2006). Many studies in nursing research have used this theory as a theoretical framework in testing job satisfaction among nurses (Kacel et al., 2005; Mitchell, 2009; Jones, 2011). The results of those studies support Herzberg’s motivation-hygiene theory, and assert that the hygiene factors are less important to job satisfaction; however, the motivation factors are most important and can lead to job satisfaction. This theory seemed to identify and explain the phenomena of job satisfaction.

Abstract: The purpose of this work was to evaluate the influence of filtration on the quality of olive oil. The influence on some physicochemical and sensorial properties was also evaluated. Results showed that free fatty acids of unfiltered oils were higher than filtered olive oils, while peroxide values were low in unfiltered oils. After filtration, the oxidative stability was reduced. The decrements in phenols content were occurred by the filtration process, causing drooping in the oxidative stability for all filtered extra virgin olive oil samples. The results could help olive oil producers to improve EVOO quality and establish the optimal storage conditions.

Abstract: Coastal areas are environmentally and economically important areas supporting a many industrial installations and highly populated areas. One of these areas is Jazan region which is located in the southern part of Red Sea along the coast of Saudi Arabia. It is characterized by the diversity of natural environment e.g. coral reefs, fisheries and vegetation. It is one of the fastest developing areas in the Kingdom which is suffering by the increasing human activities such as reclamation of the coast, urbanization and fishing activities along the coast, resulting in the degradation of coastal areas and marine environment. This study was carried out in order to review and assess the current the status of coastal habitat of coral reefs and identify the degree of degradation of corals. Coral and reef fish assessments were accomplished at three sites offshore islands at Jazan region using Reef Check belt transects and video belt transects. The results showed that fishing activities inflict serious damage to the biota. High extent of bleaching have been observed near the sampling transects and might be attributed to sea surface temperature (SST). Nevertheless, coral reefs in Jazan region showed low levels of anthropogenic disturbances. Coral reef areas and fisheries management should be considered and incorporated in the management plans to reach sustainable development.

Abstract: Green construction is a process to construct buildings with minimum harmful effects on human health and environment. One of the main strategies to achieve green buildings is to improve air quality. This can be fulfilled by choosing building materials with low natural radionuclides content namely Uranium (238U), Thorium (232Th) and Potassium (40K) in order to control the natural radiation exposure for residents of dwelling. Concrete is a man-made construction material consists of different components with high degree of non-homogeneity. The individual radiological properties of each component affect the radium equivalent and radon exhalation rate of concrete. Consequently, the knowledge about natural radionuclides content and radon exhalation rate of concrete as well as other building materials before concrete mix design and construction process will promote the assessment of radon gas and gamma rays emission inside buildings. In this work, data about radon exhalation rate (Bq m-2h-1) and natural radionuclides content (Bq/kg) in concrete ingredients and finishing materials used in Egypt were collected. Then, radium equivalent (Raeq) was calculated to assess gamma ray emission from each concrete ingredient and finishing material. All data are set in an excel sheet for different concrete mixes to train and validate an Artificial Neural Network (ANN) to predict radium equivalent and surface radon exhalation rate from concrete. The created ANN appears a good response in which the outputs are very close to the target. The created ANN model has a best validation performance (MSE) 0.000010618 at Epochs 1 and a maximum correlation coefficient close to 1. Different concrete mixtures using different cement content (350, 400, and 450 Kg/m3) and different types of coarse aggregates commonly used in Egypt (limestone, dolomite, gravel and granite) were set as a simulation data in the created ANN model to predict radon exhalation rate and radium equivalent. Indoor radon concentrations were estimated using the predicted values of radon exhalation rate from concrete beside radon exhalation rate from some finishing materials.

Abstract: Maize is grown for its grain and fodder purpose and mungbean for its protein rich seeds. In order to enhance per unit area yield, there is dire need of growing maize by using more economical techniques. Present study was conducted to evaluate the effect of different rates of zinc sulphate on hybrid maize grown alone and in combination with mungbean at Post Graduate Agricultural Research station, Jhung road, Faisalabad during March 2015. Maize hybrid (DK-6103) and NIAB mung-2006 were used as test crops. The experiment was in two factor factorial under randomized complete block design (RCBD) with plot size of 3.6 9 m. Single row hand drill and dibbler were used for sowing following intercropping pattern of sowing maize and mungbean. Results of study showed that ZnSO4 @ 18 kg ha-1 increased grain yield, plant population per m-2 and oil contents in maize alone, maize protein contents, maize grain yield equivalent in maize + two rows of mungbean, no. of seeds/pod in maize + one row of mungbean and protein contents in mungbean alone. ZnSO4 @ 12 kg ha-1 increased the no. of pods in mungbean alone. ZnSO4 @ 6 kg ha-1 enhanced no. of plants per m-2, grain yield and biological yield in mungbean alone. No zinc boosted grain weight per cob in maize + one row of mungbean and 1000-grain weight in maize + two rows of mungbean, biological yield in maize alone and 1000-grain weight of mungbean alone. Sole cropping of maize and intercropping of maize+ 2 rows of mungbean should be followed by using ZnSO4 @ 18 kg ha-1.

Abstract: Multiple sclerosis (MS) is part of a spectrum of idiopathic inflammatory demyelinating diseases (IIDDs) of the central nervous system that vary from each other by lesion size and number, pathology and clinical outcome, The study is funded by Najran university –dean ship of scientific research –seven phase funded research study it is the first incidence study done in najran province concern multiple sclerosis in Najran –king khlied hospital Diagnosis for 5 years latter (2011-2017)is achieved using consensus clinical and magnetic resonance imaging (MRI) criteria that document white matter disease disseminated in time and space. The clinical manifestations, temporal course and pathology of MS are heterogeneous, in part because it results from complex interactions of multiple genetic and environmental factors. Researcher review recent advances in understanding the incidence rate of the disease in Najran base on the genetic and environmental epidemiology and the natural history of MS. The first incidence study in Najran providence at king kalied hospital -Najran university –Funded Research Project –Seven phase, Number of research project: NU/MID/15/003. The study achieved that multiple sclerosis is common in women rather than men have tendency for later disease onset with worse prognosis in the study researcher find that women who have MS in sample was 84.6% of the sample and men were 15.4% only of the sample so the findings agree with literature review The study reveal that MS below 19 years was 38.5% of the sample have disability form, 100% all the study cases have relapsing remitting (RRMS) multiple sclerosis type so the study findings agree with literature review 85% of MS cases were (RRMS). The first clinical study of MS in an Arab country was in 1958 and largely reflects the practice of a neurologist in Baghdad, Iraq. In summary, the aetiology of MS is complex and probably involves interaction between certain genetic factors and an environmental trigger(s). It is reasonable to conclude that MS is less common in Arabs than western countries, while acknowledging that rural and remote cases, especially mild, have not been captured for Arab populations. Researcher recommended that another incidence study, clinical manifestations will be done in near future in Najran providence Forests.

Abstract: In this study, we found that thymoquinone potently inhibited the viability of the human invasive breast cancer cell lines, MDA-MB-231 (IC₅₀6.13μg/mL (24h), 3.28μg/mL (48h) and 1.76μg/mL (72h). Thymoquinone had a cytotoxic effect and induced apoptosis in MDA-MB-231 breast cancer cells as indicated by acridine orange/propidium iodide-stained cells at different time points after thymoquinone treatment. In addition, we demonstrated that thymoquinone induced cell cycle arrest at G0 phase. Treatment of MDA-MB-231 cells with thymoquinone significantly elevated intra-cellular ROS formation, which plays a pivotal role in cell death. Thymoquinone induced activation of caspase-9, caspase-8 and caspase-3/7. We also found that thymoquinone, at high concentration, could inhibit nuclear factor kappa B activation, a key molecule in tumor progression and metastasis. In addition, Western blotting analysis showed that treatment with thymoquinone resulted in down regulation of Bcl-2 and heat shock protein 70 and up regulation of Bax in the MDA-MB-231 cell line. Our results suggest that thymoquinone is a potentially useful agent for the treatment of breast cancer.

Abstract: Development of sunflower hybrids with better performance in current scenario of climate change is a dire need of present time. Currently, almost all the hybrids grown by Pakistani farmers are of exotic in their origin. This study was intended to evaluate the locally developed sunflower hybrids for seed yield and its components. Twenty-eight sunflower hybrids were grown in randomized complete block design (RCBD) with three replication during Spring 2015. The data was recorded for days to 50% flowering, plant height, stem diameter, leaves per plant, head diameter, 100 kernel weight, kernel per head, kernel weight per head, days to maturity, oil percentage and seed yield. The data was evaluated by using cluster and principle components analysis (PCA). Principle component (PC) analysis revealed that out of 10 PCs, first 2 PCs has the Eigen value larger than one. 73.7% variability was assessed among the sunflower hybrids for yield related traits, contributed by these two principle components. PC 1 contributed the maximum (59.7%) towards diversity and all the traits in it showed positive factor loading. Plant height, stem diameter and days to 50% flowering being the most important characters in PC 2. Cluster analysis grouped 28 sunflower hybrids into three diversified classes. Cluster 1 and 2 comprises of 7 and 8 hybrids respectively, while the third cluster embraces 13 sunflower hybrids. All the traits except 100 kernel weight in the cluster 1 had highest values hence, contributing maximum in seed yields. Selection could be made from cluster 2 for 100 kernel weights. Cluster 3 had the minimum values for days to 50% flowering, leaves per plant and 100 kernel weight. Selection may be avoided in these parameters from this cluster. For achieving higher 100 kernel weight cluster 1 and 2 may be combined and likewise for accomplishing higher oil contents cluster 1 may be combined with cluster 3. Out of 28 sunflower hybrids, FH-516 proved its worth by producing seed yield at par with Hysun-33.
