In present study oilseeds were collected from different parts of Marathwada region and screened on different media for the incidence of different fungal species. Thirty fungal species were found to be associated with oilseeds. A study was also conducted to determine the antifungal activity of essential oils and gums of some medicinal plants against storage fungi. Eucalyptus oil and gum of Terminalia arjuna, Acacia Arabica and Butea monosperma inhibited the growth of storage fungi.

In today’s competitive business world understanding and developing Employee Competencies remains the key to Organisational success. Understanding employee competencies requires a focused approach to study the key competencies possessed by the employees and hence the study was carried out. The purpose of the study is to investigate the level of employee competencies and to analyse the most and least possessed competencies among employees of manufacturing units across the automobile corridor in Chennai, TamilNadu, India. A structured questionnaire was framed and circulated among the respondents to collect the primary data used for research. The respondents were selected through convenient random sampling method. Data collected from 227 respondents were tabled in SPSS and was anlaysed using statistical tools like factor analysis, reliability analysis and Correlation. The study intends to provide a pragmatic view on the level of competency among the employees and provides insights to the administrators, policy makers and practitioners in the field of human resource management for implementing the findings in developing the competency of employees for the development of the individual and the organisation.

Web caching and Web prefetching are two important techniques used to reduce the noticeable response time perceived by users. By integrating Web caching and Web prefetching, these two techniques can complement each other since the Web caching technique exploits the temporal locality, whereas Web prefetching technique utilizes the spatial locality of Web objects [30]. In this paper, we develop algorithm Pre-IPGDSF# by integrating Web caching and Web prefetching in Web servers. For caching, we use innovative algorithm Intelligent Predictive Greedy Dual Size Frequency#, IPGDSF#, which is an enhanced version of algorithm GDSF# developed by us [13, 14, 15, 16, 17]. For prefetching, we use a static prefetching method. Using three different Web server logs, we use trace driven analysis to evaluate the effects of different replacement policies on the performance of a Web server. We specifically compare policies like GDSF, GDSF#, and IPGDSF# with the proposed integrated policy Pre-IPGDSF#. Using trace-driven simulations and for various standard cost criteria (hit rate and byte hit rate), we show that our proposed integrated policy outperforms all other algorithms under consideration.

This paper investigates a 2-D discrete time predator - prey interaction model. The equilibrium points are obtained and stability of the equilibrium points is analyzed. The phase portraits are obtained for different sets of parameter values. Also a bifurcation diagram is presented. Numerical simulations are performed and they exhibit rich dynamics of the discrete model.

The study of mineral contents of fresh and dried tilapia fish (Oreochromis niloticus) from Mcaiver Market, Warri South Local Government Area of Delta State, Nigeria were determined. The tilapia fishes were shared into two parts: one part was used to determine the mineral content of the fresh fish and the other part was oven dried before the analysis of mineral contents of both fishes. The minerals detected were in the order Na>Ca>K>Mg>Zn>Fe. It was observed that dried tilapia fish was more nutritional than the fresh tilapia fish. Dry tilapia fish should be consumed rather than fresh tilapia fish for proper nourishments.

Till date polymeric membranes play a major role in Reverse Osmosis Desalination Industries. Many researchers have been concentrated in order to develop optimum polymeric membranes. The optimization is done in previous decades by controlling the membrane formation reactions and by use of catalysts and some additives but the emergence of Nano-technology in membrane could provide a better alternative for polymer based membranes. In this research a general review on different conventional membrane process that are currently employed are discussed and how Nano-structured membranes that can be employed which will enhance the Reverse osmosis desalination performance and but number of challenges remain with regard to their practical execution.

Analysis of earth dams Stability, and their arching phenomenon, is one of the most important issues in geotechnical engineering. Arching dam, you can use one or more methods are analyzed. The main factor of instability dams, gravity effect, but other factors can, intensify or provoke them to be effective. To understand the factors intensifying landslide, could contribute significantly to the experts, and the stability of the dam dirt, and prevent the arching. The purpose of this paper is to examine the phenomenon of arching in the bathroom tight barrier with finite element method, and compared with studies of dam instrumentation, numerical analysis by finite element software PLAXIS, has been made. Analysis, using behavioral models Mohr-Coulomb, is done. On the other hand, we can say that, numerical methods in the analytical methods is very rapid, reliable and accurate, and therefore these methods, able to perform parametric studies, the boundary conditions are complex. So in this study, AH stresses dam Tang-e Hamam, has been studied, and then perform parametric studies, it was concluded that increasing the angle of internal friction shell dam, the dam will lead to increased confidence. However, by changing the geometry of the dam core, core thickness miles to miles and increase confidence rises Dam. Also, the arching, the barrier height is variable, and strongly arching and the maximum arching, core thickness depends on the height of the dam.

This study is a first neuropsychological evaluation of cognitive Impairment generated by the job strain to the teleoperators in call centers in sub-Saharan Africa; Particularly in the Democratic Republic of Congo, city of kinshasa. This study established a statistically significant relationship between Exposure to psychosocial factors (high psychological demand and low decision latitude) and the appearance of job strain in teleoperators. It also showed a statistically significant relationship between job strain and the appearance of cognitive disorders in teleoperators. Lastly, the exposure duration at the call center of six months or more, was retained as necessary time to see the psychosocial factors negatively impacting the mental health of the call center teleoperators.

This paper takes a look at Campus Radio Presentation World from analytical secondary data and observers discovery over a span of many years of professional radio broadcasting practice and offered different perspectives with recommendations for excellent presentations on Campus Radio.

In this paper, a helical coil tube in tube heat exchanger was designed and used in carbon dioxide solar assisted heat pump system (SAHP) to provide hot water for domestic applications and to operate an air gap membrane desalination (AGMD) unit. Both theoretical and experimental studies to investigate the performance of the gas cooler with Glycol Ethylene 50% and water as coolants were performed. The experimental part to study the behavior of the carbon dioxide in the supercritical region was conducted on the R744 heat pump test rig located at Department of Energy and Process Engineering – NTNU. On the other hand, FEA using ANSYS Fluent 18.1 was used to conduct the theoretical analysis. The study includes effect of inlet temperature of both coolants, effect of discharge pressure, effect of mass flow rate of water, and logarithmic mean temperature difference (LMTD). Good agreements between Experimental and simulation results were achieved. Results showed that the outlet temperature of the refrigerant from the gas cooler decreased from 81 oC to 40 oC, with 0.085 bar average pressure drop due to the heat rejection process. The outlet temperature of the refrigerant from the gas cooler in case of water is 8 oC lower than with ethylene glycol 50%. The outlet temperature of water reached 57 oC which is enough for domestic applications and to operate the AGMD unit to produce fresh water. It is observed that the pressure drop in the refrigerant by using water as coolant is higher by 0.2 bar than when ethylene glycol 50% used. Results also revealed that the value of LMTD of the gas cooler using ethylene glycol 50% is 24.3 % higher than the LMTD value when using water.
