The Development Of Biomagnetic Systems : Planar Gradiometers And Software Tools

This thesis is concerned with two aspects of the design and construction of biomagnetic systems. Firstly, it considers the optimum design of planar gradiometers. The modelling of gradiometers is discussed and an algorithm for optimising the sensitivity of a specific type of gradiometer is presented. A test thin-film procedure for the manufacture of a planar gradiometer is outlined. The performance of three different types of gradiometer in recovering test current distributions, using a distributed current analysis technique, is assessed. Secondly, four major software tools that are essential in the analysis of data from large multi-channel biomagnetic systems are presented. These tools are then used to analyze data from a visual evoked response experiment. The system used to collect data was the Helsinki multi-channel system which consists of 24 planar gradiometers. The results confirm the retinotopic mapping of visual field information, and suggest that the time evolution of activity in different parts of the visual cortex is similar for early latencies

Prediction of Flow in Non-prismatic Compound Open Channel using Artificial Neural Network

Every stream on the planet is one of a kind. Some are tenderly bended, others are wind, and some others are generally straight and skewed. The extent of stream geometry additionally changes from segment to area longitudinally because of various pressure driven and surface conditions called non-prismatic channel. A significant part of the examination work are observed to be done on prismatic compound channels. There has additionally been an advancement of work found for winding channels. However, a time which has been dismissed is that of the work for non-prismatic compound channels. An exertion has been made to investigate the examination business related to non-prismatic directs in various sorts of stream conditions. A trial perception has been made to examine the speed appropriation, limit shear stress dispersion and vitality loss of a compound channel with merging surge plain. The computation of Depth normal speed, vitality misfortune, limit shear stress in non-prismatic compound channel stream is more perplexing. The expectation of the stream qualities in compound channels with prismatic and non-prismatic floodplains is a testing assignment for power through pressure engineers because of the three dimensional nature of the stream Basic traditional methodologies can't foresee the aforementioned stream attributes with adequate precision, subsequently here can effortlessly implementable system the Artificial Neural Network can be utilized for forecast, approval and investigation of the stream parameters specified. The model performed entirely agreeable when contrasted and the other traditional strategies

Effect of Various Nursery Media on Onion Seedlings Development

A field experiment was conducted to standardize the nursery raising technique for onion at the Horticulture Research Farm, Department of Horticulture, Allahabad Agricultural Institute-Deemed University, Allahabad, during 2005-2006. The treatments comprised combinations of soil, sand, FYM and vermicompost. Altogether, 14 treatments were applied in a randomized block design with three replications. Hundred percent germination was found with a combination of soil, sand and FYM in proportions of 2:1:2&2:2:1, and, 1:1:1&2:2:1 Soil:Sand:Vermicompost. Among all the treatments, the combination of soil 2 parts, sand 1 part and FYM 2 parts, significantly influenced growth and health of seedlings and produced the maximum seedling height (11.42 cm), stem diameter (0.33 cm), root length (10.86 cm), shoot fresh weight (6.96 g), root fresh weight (3.22 g), total seedling fresh weight (10.18 g), shoot dry weight (3.95 g), root dry weight (1.53 g) and total seedling dry weight (5.48g). Highest benefit:cost ratio of 3.72 was also seen in this treatment combination

ANTIDIABETIC ACTIVITY OF METHANOLIC EXTRACT OF NEPETA HINDOSTANA HERB IN STREPTOZOTOCIN INDUCED DIABETES IN RATS

Objective: The present work was designed to evaluate the antidiabetic effect of Nepeta hindostana methanolic extract in streptozotocin-induced diabetes in rats.Methods: Wistar rats were divided into different groups and glibenclamide (2.5 mg/kg), and Nepeta hindostana methanolic extract (100, 200 and 400 mg/kg) treatments were given orally, for 28 d. Change in body weight, glucose level, lipid profile, total cholesterol, and triglyceride level in tissue homogenates, total hemoglobin, and HbA1C and pancreas microscopy of different groups were evaluated.Results: Nepeta hindostana methanolic extract 200 and 400 mg/kg dose group have a significant change in weight as compared to diabetic control. All the extract treated groups showed a significant reduction in glucose level on 14th and 28th day as compared to diabetic control. The level of serum total cholesterol and triglyceride level were significantly reduced, and HDL level significantly increased in 400 mg/kg groups after 28 d treatment. However, a significant increase in Hb concentration was observed in diabetic rats treated with 200 and 400 mg/kg, when compared to diabetic control. The microscopy of the pancreas showed both glibenclamide and 400 mg/kg extract does appear to regulate diabetes at the cellular level resulting in restoration of near normal architecture pancreatic islets of langerhans and hepatocytes.Conclusion: It can be concluded that Nepeta hindostana methanolic extract exhibit significant antidiabetic activity against streptozotocin-induced diabetes model.
