Fuel cells are electrochemical devices that convert the chemical energy of a fuel directly and very efficiently into electricity. Here we report a new class of electrolyte, i.e. polycrystalline dehydrated salts as an intermediate temperature fuel cell electrolyte. The porous conduction in the dehydrated salts was established by the study of DTA/TGA, transference number, bulk electrical conductivity measurement and EMF study. <br/> <br/>Page(s): 117-123 Wed, 28 Nov 2007 22:58:59 GMT http://nopr.niscair.res.in/handle/123456789/3180 Title: Economic analysis of fish production and its marketing <br/> <br/>Authors: Singh, Manish Kumar; Singh, Alok Kumar <br/> <br/>Abstract: A study was carried out at Cheraigaon Block of Varanasi, V.P. to estimate the economic analysis of fish production and its marketing. Results revealed that average cost of fish production was estimated to Rs. 12.55 per kg whereas its marketing cost was estimated to Rs. 126/quintal. Marketing cost includes transportation, weighing charges and maintenance. Cost of production includes its feed, labour, manure & fertilizer, seed, disease control, rent, interest and wear & tear. Average net income from fish production was estimated to Rs. 30/kg and the average net profit was estimated to Rs 16. 18/kg. <br/> <br/>Page(s): 152-155 Wed, 28 Nov 2007 22:58:59 GMT http://nopr.niscair.res.in/handle/123456789/3178 Title: Fungal toxicity in stored pods and seeds of Acacia senegal <br/> <br/>Authors: Bohra, N K; Purohit, D K; Gehlot, Praveen <br/> <br/>Abstract: Acacia senegal L is a naturally occurring tree species of arid Rajasthan. Fresh and stored seeds and pods are eaten by local inhabitants. From stored seeds and pods 17 different mycroflora of a 8 genera were isolated. Incidence of Aspergillus flavus was consequently higher in stored seed samples (28-48%) in comparison to pods (20-38%) and 38 isolates were found to be toxigenic and produced aflatoxins out of 78 isolates screened. Out of 51 samples, 39 found to be naturally contaminated with aflatoxins. <br/> <br/>Page(s): 160-163 Wed, 28 Nov 2007 22:58:59 GMT http://nopr.niscair.res.in/handle/123456789/3177 Title: Synthesis of some heterocyclic compounds of nitrogen <br/> <br/>Authors: Shukla, I C; Yadav, Santosh Kumar; Kumar, Vinod; Kumar, Santosh <br/> <br/>Abstract: The present paper describes synthesis of 7-bromo-9-methyl phenothiazines by Smile's rearrangement of 5-bromo-3-methyl- 2-formamide-2'-nitrodiphenyl sulfides. The above compounds are obtainted by the formylation of 2-arrllno-5-bromo-7methyl- 2'-nitrodiphenyl sulfides. These are prepared by the condensation of 2-amino-5-bromo-3-methyl benzenethiols with o-halonitrobenzene. <br/> <br/>Page(s): 167-171 Wed, 28 Nov 2007 22:58:59 GMT
