- ItemProtective Mechanisms of Moringa oleifera against CCl4-lnduced Oxidative Stress in Precision-Cut Liver Slices(2010) Padma, P RObjective: The present study was designed to evaluate the efficacy of Moringa oleifera leaves against carbon tetrachloride (CCU-treated liver slices in vitro. Material and Methods: The study evaluated the antioxidant properties of Moringa oleifera leaves against GCh-induced oxidative damage in liver slices. Results: CCU treatment significantly decreased the activities of antioxidant enzymes such as superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase, and glutathione S-transferase and caused decreased glutathione cbntent and increased the thiobarbituric acid-reacting substances (TBARS). Treatment with Morinqp oleifera extract increased the activities of antioxidant enzymes and glutathione content and reduced the levels of TBARS significantly. Observed reduction in the level of lipid! peroxides showed a decreased tendency of peroxidative damage. Discussion and Conclusion: We conclude that, under these experimental conditions, the leaf extracts effectively suppress CCU-induced oxidative stress. Our findings provide evidence to demonstrate that the possible mechanism of this activity may be due to the strong antioxidant property of the leaves.

- ItemEmpirical Evaluation of Suitable Segmentation Algorithms for IR Images(2010) Padmavathi, G; Subashini, PImage segmentation is the first stage of processing in many practical computer vision systems. Development of segmentation algorithms has attracted considerable research interest, relatively little work has been published on the subject of their evaluation. Hence this paper enumerates and reviews mainly the image segmentation algorithms namely Otsu, Fuzzy C means. Global Active Contour / Snake model and Watershed. These suitable segmentation methods arc implemented for IR images and arc evaluated based on the parameters. The parameters arc Variation Of Information (VOI), Global Consistency Error (GCE) and Probabilistic Rand Index (PRI). The objective of the paper is to identify the best segmentation algorithm that is suitable for IR images. From the experimentation and evaluation it is observed that the Global Active Contour/Snakc model works better compared to other methods for IR images.
- ItemDeterminants of Agricultural Credit by Scheduled Commercial Banks - A Comparative Study in the Pre and Post Reform Period(2010) Annapoorani, RAgricultural credit is one of tltc most crucial inputs in the adoption of technological innervations, modernization of agriculture, to improve productiinty and for all agricultural development programmes. Scheduled commercial batiks were a predominant source o f institutional credit to the farmers. The share ofSCBs in total institutional credit to agriculture has increased from 50.03 per cent in 1998-99 to 77.89 per cent in 2008-09. The research study on "Determinants of Agriailhiral Credit by Scheduled Commercial Banks-A Comparative Study in the Pre and Post Reform Period" was formulated with the objectives of to compare the provision of agricultural credit by SCBs between pre and post reform period and to identify the determinants o f agriailtural credit provided by SCBs during the pre and post reform period. The study zoas related to the period 1^80-81 to 2006-07 and the required data xoere compiled from the secondary sources. Compound growth rate,, t test and regression analysis were used fo r the analysis. The study found that the direct agricultural credit provided by the scheduled commercial banks at constant prices had shown an increasing trend with fluctuation. In the post refyfni period the share df direct agricultural credil ut both curimi arid Wasiihti^iaiiy signifwan f mditpid^iitfoe. rdafdm^fy with ike advances. But iuthe post reformperiod, along with tlie amount o f deposits, the area under high yielding varieties was also statistically significant. As such to increase • the direct agricultural adi>ances, the commercial banks should be strictly regulated to follow the percentage o f net bank credit towards direct agricultural advances. Further, proper extension services-should be made to increase the area tinder high yielding variety seeds.
