The traditional medicines (i.e. herbal medicines / Spices) are cost effective & have negligible side effects. There is a need for credible research to investigate the proper use, adverse effects and precautions associated with these products. Hence, the current study was carried out to observe the hepatoprotective effect of Curcuma Longa (C.L) in Nitro-Methane Sulfonamide (N-MS) induced hepatotoxicity. 40 male albino wistar rats were divided into four groups. In group A, normal diet was given for 09 days while in group B, N- MS was given for 09 days followed by CL powder for next 09 days; while CL powder for 09 days followed by N- MS for next 09 days was used in group C. Group D received N-MS in adjunct with C.L powder for 09 days. Blood samples from each group were taken for biochemical analysis of serum levels of ALT, AST, Alkaline Phosphatase and GGT. The results of present study have concluded that the administration of C.L significantly offered protection against damaging effects of N-MS.

The optimal tilt angle of solar photovoltaic panel in Ilorin, Nigeria was determined. The solar panel was first mounted at 0o to the horizontal and after ten minutes, the voltage and current generated with the corresponding atmospheric temperature were recorded. The same procedure was repeated for 2o to 30o at a succession of 2o at ten minutes time interval over the entire measurement period. The result obtained shows that the average optimal tilt angle at which a solar panel will be mounted for maximum power performance at fixed position in Ilorin is 22o. This optimum angle of tilt of the solar panel and the orientation are dependent on the month of the year and the location of the site of study.

Lot of attention has been given towards natural healthy therapeutic foods by health professional and the common population for improving overall well being, as well as in the prevention of diseases. In this connection, many grains and fruits have been regarded in functional foods. When such ingredients are added into food preparation with an objective of imparting health benefit is the need of the hour. With this aim, a venture was made to develop a bakery product and evaluate its organoleptic attributes. A chocolate pound cake was formulated and in which desired proportions of kavanai rice and Tribulus terrestris fruit powder were added and thus 5 varieties of cakes were prepared and its sensory attributes were compared with the standard cake. 9 point hedonic scale was used to assess sensory characteristics via colour, appearance, flavour, taste and overall acceptability. Garrets ranking tool was employed to assess the ranking of hedonic score. The overall acceptability of cake 2 (80% Refined Wheat Flour and 20% Tribulus terrestris fruit powder) and cake 3 (100% Refined Wheat Flour and 10% Tribulus terrestris fruit powder) had the highest score of 8.55 and was comparable with standard cake. It was imperative that addition of 10% Tribulus terrestris fruit powder into chocolate cake without addition of Kavanai rice scores highest for its sensory attributes. It is concluded that kavanai rice and Tribulus terrestris fruit powder could serve as potential functional ingredients in the development of therapeutic foods. Key Words: Tribulus terrestris fruit powder, Kavanai rice, functional foods, Chocolate Pound Cakes.

Marine mycology is one of the major emerging areas or research in tropics. It is gaining importance not only due to taxonomic and ecological perspective, but also for unique metabolites biochemical and enzymes from the sea. Majority of the studies on marine fungi are confined to the temperate regions. Studies in tropics and subtropics gained importance only in last two decades. So in this present study addresses the marine fungi undertaken in tropical/subtropical habitats especially driftwoods in muthupet mangroves. Diversity of marine fungi colonizing the drift wood samples was assessed and the common and dominant driftwood inhabiting marine fungus were grown on seven different media. A total number of 23 species (11 genera) of fungi were recorded from the driftwood samples collected from five different stations of Muthupet mangrove (Chief corner, Koraiyar River, Saradi, Sethuguda, Xavier Munai). They were assignable to ascomycotina (3 species), basidiomycotina (1 species) and Deuteromycotina (19 species). The common and dominant marine fungus was showed fast growth in SWPDA.

A general framework for the development of a new generation of PM Linear Oscillating Machine (PMLOM) using FE magnetic analysis suitable for short strokes is described in this paper. A microcontroller based IGBT inverter is developed for the control of thrust and oscillation frequency. The PMLOM can perform precision oscillation task with relatively low power dissipation. The use of powerful permanent magnet material such as Neodymium-Iron-Boron alloys has greatly improved the performance of the machine. The forces for aluminium mover embedded with rare earth permanent magnets are determined analytically and the results are validated extensively by comparison with finite element analyses.

The BPO industry in India has become a growth engine for the economy. It has achieved staggering growth in the last 10 years of its operation, adding 5 million jobs and USD 15 billion in its revenue. 5 million jobs naturally imply that 5 million people are working in some capacity or the other for the industry. This makes the job of HR all the more demanding, and important. Human resource is responsible not just for procuring the right kind of people for the right jobs, it also makes sure that these people stay with the company, and, during their stay contribute optimally to the company’s development. Although, in a BPO, it is relatively simple to lay down the technical qualifications of the job, the channel through which people with such qualification can come to the company, and the manner in which these aspirants can be evaluated. The high attrition rate in the industry is primarily due to the restricted career options or growth opportunities for the youngsters. Fear of stagnation is a major factor that forces the employees to quit the industry. While some leave their career mid-way in pursuit of higher education, others are drawn in by the higher pay packages offered elsewhere. The new entrants into the BPO sector, who are consistently on the lookout for trained youngsters, offer higher remuneration. With the employees moving to other jobs in less than a year, the industry has to confront the gnawing problem of attrition.
