Interfacing of High Temperature Z-meter Setup Using Python

In this work, we interface high temperature Z-meter setup to automize the whole measurement process. A program is built on open source programming language Python which convert the manual measurement process into fully automated process without any cost addition. Using this program, simultaneous measurement of Seebeck coefficient, thermal conductivity and electrical resistivity are performed and using all three, figure-of-merit (ZT) is calculated. Developed program is verified by performing measurement over p-type Bi0.36Sb1.45Te3 sample and the data obtained are found to be in good agreement with the reported data.Comment: 3 pages, 4 figures, Accepted for publication in AIP Conference Proceeding

A study of evaluation of various risk factors of retinal vein occlusion

Background:A study of various ocular & systemic risk factors in Retinal Vein Occulation (RVO) at tertiary eye care centre.Methods:A prospective study included 50 eyes of 50 patients, in period of September 2010 to August 2012. Inclusion criteria: 1. Age >25 years, 2. All newly diagnosed cases of vein occlusion. Exclusion criteria: 1. Age <25 years 2. All other ocular diseases causing significant visual impairment. A detailed history, ophthalmic & systemic examinations with all necessary investigations-as and when required were done.Results: In our study, RVOs were more common in males – 26 (52%) & in 56-65 years of age group - 16 (32%). BRVO (Branch Retinal Vein Occlusion)s were more common than CRVO (Central Retinal Vein Occlusion) - Nonischemic (26%) >Ischemic (24%). In risk factors - most common was hypertension - in 38 (76%) patients. Followed by descending order, hyperlipidemia 27 (54%) >diabetes mellitus 16 (32%) >tobacco 14 (28%) >hyper homocystinemia 4 (8%) >severe alcohol 2 (4%). The complications were more in ischemic than Nonischemic-CRVO >BRVO - they were macular edema 43 (86%) >neovascularization at iris - 14 (28%) >neovascularization at angle - 10 (20%) >neovascular glaucoma – 4 (8%). Conclusion:RVOs are more common with increasing age, in males & most common risk factor is hypertensive. Most common cause for vision loss is macular edema - ischemic >non-ischemic.

Ileo-anal pouch necrosis secondary to small bowel volvulus: A case report

<p>Abstract</p> <p>Introduction</p> <p>Small bowel volvulus is a rare occurrence in the Western world and its occurrence after ileo-anal ouch formation is even rarer.</p> <p>Case Presentation</p> <p>We report a case of a 26 year old lady who presented with small bowel volvulus and subsequent ischaemia and necrosis of her ileo-anal pouch created 5 years previously.</p> <p>Conclusion</p> <p>This case illustrates a rare but potentially devastating complication of ileo-anal pouch formation and as such the diagnosis should be borne in mind when a patient with a pouch presents with an acute abdomen.</p

Crop Diversification an Effective Strategy for Sustainable Agriculture Development

Sustainable agricultural practices involve a variety of approaches. The most important approached for sustainable agriculture development is crop diversification. It allowing the farmers to employ biological cycles to minimize inputs, conserve the resource base, maximize yields and also reduce the risk due to ecological and environmental factors. It serves as an important opportunity to augment income and employment generation for rural communities. Crop diversification promotes the interaction of beneficial soil bacteria, interrupts the disease cycle, and reduces the quantity of weeds. Crop diversification boosts land-use efficiency and crop output by improving the physical and chemical qualities of soil. Crop diversification shows a lot of scope to alleviating the problems such as resurgence of insects-pests and weeds, soil degradation, environmental pollution, soil salinity, decline farm profit and climate change. Crop diversification through crop intensification system enhanced the net returns, B:C ratio, and overall system productivity of a farm. In order to achieve the benefits of crop diversification farmers are shifting from low value low yielding crops to high value high yielding crops. Thus, crop diversification has the sound capacity for achieving the goal of nutritional security, income growth, food security, employment generation and sustainable agriculture development
