Authors: Dwivedi, Mrigank Mauli; Pandey, Kamlesh; Tripathi, Mridula
Abstract: The main advantage of the non-conventional energy sources over the conventional energy sources is its cleanness, low chemical
and noise pollution, high fuel efficiency with better fuel flexibility and economy. 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.

Authors: Singh, Manish Kumar; Singh, Alok Kumar
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.

Authors: Bohra, N K; Purohit, D K; Gehlot, Praveen
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.

Authors: Shukla, I C; Yadav, Santosh Kumar; Kumar, Vinod; Kumar, Santosh
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.
