²Research Scholar, Department of Physics, IFTM University Moradabad

Abstract: In this paper we will discuss the all numerical methods are extensively used to analyze the performance of the behavior for computational flow and also to design the two phase micro-channels heat exchanger. Computational Fluid Dynamics (CFD) is a computer-based numerical tool used to study the fluid flow and in this we can transfer the flow dynamically, heat transfer behavior and also its associated phenomena such as chemical reaction. A set of mathematical model equations are first developed following conservation laws. These equations are then solved using a computer programmed in order to obtain the flow variables throughout the computational domain. A theoretical study of single phase micro channel heat exchanger has been carried out. Hence, the study of fluid flow and heat transfer in micro channels which are two essential parts of such devices, have attracted more attentions with broad applications in both engineering and medical problems.

Abstract: The rather vexatious and disturbing problem of stress is increasingly becoming more intense and persistent in modern life with its accelerated tempo. People may suffer from stress because they are usually in positions where they can't avoid it. Therefore, in the present complex industrial and organizational life one has to effectively manage stress, otherwise he will be its ultimate victim, with attendant poor- performance, Imbalanced psychological we1lbeing or a run-down physical health. Stress is not necessarily destructive or bad. Channeled properly stress can be energizing, stimulating and growth producing. While some amount of stress in the work environment is inescapable, perhaps even necessary - beyond a point, stress has a negative effect on the physical and psychological health of the employee. In the long run, stress can be counter-productive to the organization as well as poor performance, decline in morale and loss of vitality is potential organizational costs of mismanaged stress. The current study is conducted to identify the causes of stress of faculty members at Higher Education in India. For the purpose, various colleges and Universities of Kashmir Division are selected as representative of Population. A sample of 300 faculty members (Professors, Associate Professors and Assistant Professors) responded to the study. Data analysis shows that the Workload, Student Related issues and Role Conflicts are the major sources contributing significantly towards producing stress. The study also revealed that faculty members working in universities experienced more stress as compared to faculty working in different colleges. The study yield many significant results for the policy makers of Business Institutions in general and for the higher education institutions in particular.

Abstract: A simple sonochemical route for the surface synthesis of CdS nanoparticles on ZnO is reported. Ultrasonic irradiation of a mixture of ZnO, cadmium chloride, and thiourea in an aqueous medium for 2 h yields ZnO and CdS nanoparticle (ZnO/CdS) composites with core/shell-type geometry. The powder X-ray diffraction of the ZnO/CdS composites shows additional diffraction peaks corresponding to the hexagonally structured CdS, apart from the signals from the ZnO cores. Transmission electron microscopy images of the ZnO/CdS composites reveal that the ZnO are coated with CdS nanoparticles with typical diameters of about 5-10 nm. The room temperature photoluminescence spectrum of the ZnO/CdS composites has two emission bands: an ultraviolet emission peak at 376 nm and a green emission around 523 nm. The conductance of the ZnO/CdS composites shows an enhancement compared with that of the uncoated ZnO. The appealing application of the ZnO/CdS composites as ethanol sensors is presented and a possible sensing mechanism is discussed.

Abstract: Today fascioliasis is one of the most debilitating parasitic diseases of veterinary and human disease concern globally. Snails serve as intermediate host for parasitic flat warm of Fasciola species. One of the possible approaches to eradicate or control this problem is to interrupt the life cycle of the parasitic trematodes by eliminating the snail, which is essential to life cycle. Natural products have an advantage over synthetic products, because such products have eco-friendly, biodegradable and hence are less likely to accumulate in the environment. The molluscicidal activity of column purified fraction of Bauhinia variegata leaf, Mimusops elengi bark and their active components with synergist piperonyl butoxide (PB) and MGK- 264 were studied in binary combination (1:5) against snail Lymnaea acuminata. Binary combination of B. variegata leaf column purified and its active component quercetin and M. elengi bark column purified and its active component saponin with synergist PB or MGK-264 in 1:5 ratio was used for the determination of molluscicidal activity. Synergistic ratio of column purified fraction of Mimusops elengi bark with piperonyl butoxide (PB) (96h: 720 times) or MGK- 264 (96h: 360 times), respectively. Combinations of column purified fraction of Bauhinia variegata leaf with piperonyl butoxide (PB) or MGK-264 is more toxic than single treatment. Highest degree of synergism i.e. 199.33 times was observed in the combination of column purified fraction of leaf Bauhinia variegata with piperonyl butoxide (PB) at 96h exposure period. Toxicity of binary combination was increased hundreds fold than their individual components indicating synergistic action. It can be concluded from the present study that the use of synergist in binary combination will be more helpful in controlling the aquatic snails, than their individual components and it can be stated from the toxico-dynamic properties of Bauhinia variegate and Mimusops elengi that they have potential to act as molluscicidal agents.

Abstract: This study examined the impacts of conflict on farm resource productivity in Akwa Ibom State, Nigeria. Data for the study were collected through Multi-stage sampling technique from 114 farmers. Analysis shows that land area, quantity of fertilizer and planting materials as well as location of community are important determinant of farm outputs. The location of the community was found to have negative impact on farm outputs. This indicates the conflict status of a community could influence agricultural output from such community. The farmers were found to be efficient in the use of only family labour.

Abstract: Statement of problem: Anthropometry is applied in medical profession such as maxillofacial surgery,growth and development studies, plastic surgery, bioengineering and non-medical branches such as like shoe-making and eye-glasses industries. Aim: The aim of this study was to assessment facial anthropometric Ratios in Iranian population (Shirvan city) Materials and Methods: This cross sectional analytical study was conducted randomly on 564 boys from North Khorasan (shirvan), with normal face patterns. Facial and cranial ratios was estimated and compared. Data were analyzed by SPSS software. The regression line and the growth coefficient were determined for each Parameter. Finally, the mean values of these parameters were determined. Pared t-test were used for statistic analysis. Results: Anthropometric results obtained from 4 to 11 years old boys residing in the city of Shirvan show that there is a special discipline in growth of different parts of face and skull. We reached formulas that may have a wide range of applications such as prediction of facial situation of an individual before or after his/her present situation. Such predictions can be helpful in forensic medicine, for instance in finding the lost kids. Reaching a normal range for face dimensions through studies about growth will play an important role in maxillofacial surgery and plastic surgery as well as in study of growth disorders. Conclusion: There are different factors such as ecologic, racial, age, and sex besides all genetic factors that influence the dimensions of human body and the way of its growth and development. Since the Iranian race is a compound one and consists of different races, and there are a wide variety of body dimensions in different parts of Iran, it is necessary to conduct more studies according to the geographical factors and the facial and skull anthropometric data shall be studied in different tribes of Iran. Obtaining an average for each of the variables in Iranian race, the anthropometry studies shall be conducted for different tribes.

Abstract: The phytochemical screening of the root and stem bark of Cassia arereh revealed that the root possesses alkaloids, flavonoids, phlobatanins, saponins, steroids and while the stem back possesses alkaloids, anthraquinones, saponins, steroids and tannins. The antimicrobial activity on Shigella spp, Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa and Salmonella typhi were determined at the concentration of 200mg/ml using the disc diffusion technique. The ethanolic extract of the stem back produced the highest antimicrobial effect against E. coli, S. aureus and Pseudomonas aeruginosa with the zones of inhibition of 13mm respectively and 12mm against S. typhi compared with the other extracts. Equally, the stem back extracts were observed to be more potent against the microbial isolates than the root extracts as E. coli, S. aureus and Pseudomonas aeruginosa were observed to be resistant to stem back extracts. Minimum inhibitory concentration (MIC) and the minimum bactericidal concentration (MBC) values were in the range of 12.5mg/ml-200mg/ml concentrations. Analysis of active extracts against the test organisms showed that the activity of the extract was dependent on the solvent used and the type of target bacteria and the difference observed were significant (P<0.05).
