But as per RGGVY (Rejiv Gandhi Grammen Vidyutikaran Yojana), the rate of village electrification is much lower as household connectivity has been fairly low. The rest 15% villages and a larger proportion of households have to be electrified. Villages have been a major concern as cost of electrification is fairly high. The most favored alternative to any kind of users is generation of electricity from diesel generating sets and renewable sources of energy. But the capital cost of renewable energy equipments is fairly high. Gradually, there is a reduction in the prices of these systems due to availability of better technological options and they are becoming competitive to grid electricity. In this paper, an attempt has been made to calculate the cost of production of electricity from stand-alone, off-grid devices biomass gasifiers (both dual fuel and pure gas type) and compare with that of diesel generating sets by using the concept of LCC (life cycle costing) and Homer software. It is found that the cost of per unit electricity generation (kWh) has been always the lowest in comparison to diesel generating sets even if the price of biomass increases to some extent.展开更多

Ten isolates were isolated from 150 specimens one of them from CSF and one isolate isolated from blood samples the others isolated from food specimens 6 isolates isolated from sausage and 2 from raw vegetables. Isolates were identified traditionally involved culture methods based on selective enrichment and plating followed by the characterization of Listeria spp. based on colony morphology, sugar fermentation and haemolytic properties, identification by Api listeria was done. Determine the isolates that produce biofilm by tissue culture plate method. The highest biofilm forming strains ofListeria monocytogenes isolates appear in No. (D10, El, E5 and E7) OD reading each of them is (0.13, 0.09, 0.11 and 0.19) respectively, the lowest or poor biofilm forming strains appear in No. (D11, D12, E2, E3, E4 and E6) that optical density (OD) reading are (0.04, 0.03, 0.05, 0.04, 0.05 and 0.03) respectively by comparing with control prepared in well (A12) that stained by crystal violate without putting any isolates and the OD reading is (0.003). Confirmation by PCR was done only for four isolates that produce biofilm (D10 and El) that obtained from CSF and blood sample and for (E5 and E7) that obtained from food samples.展开更多
