Poloxamer 407 based dispersions exhibited higher dissolution ratethan Povidone K 30. Powder X-ray diffraction (PXRD) showed that degree of crystallinity decreased by increasing concentration of Povidone K 30 carrier. FTIR studies showed that drug used was compatible with carriers. Solid dispersion sprepared with povidone K30 changed crystalline form of drug to amorphous form. <br/> <br/>Page(s): 629-634 Thu, 29 Jul 2010 22:58:59 GMT http://nopr.niscair.res.in/handle/123456789/9978 Title: Microbiological investigation of activated sludge in sequencing batch bioreactor for urban wastewater treatment <br/> <br/>Authors: Ogleni, Nurtac; Topaloglu, Duygu; Dere, Turgay; Ileri, Recep <br/> <br/>Abstract: This study presents measurement of containment parameters of waste water obtained from influent and effluent of sequencing batch bioreactor (SBR). Arcella Sp. dominantly encountered in Sample I from Karaman-Adapazari-Sakarya Urban Waste water Treatment Plant in Turkey. Amount of cells belonging to Difflugia Sp., however, had increased for Sample II. In Sample III,Arcella Sp., and Difflugia Sp. lost their dominance, whereas Didinium Sp., Aspidisca Sp., Targidrade Sp., and Peranema Sp., were encountered. This finding indicates that protozoa and metazoan population in activated sludge enable daily control of waste water treatment efficiency. <br/> <br/>Page(s): 643-646 Thu, 29 Jul 2010 22:58:59 GMT http://nopr.niscair.res.in/handle/123456789/9977 Title: Wear and tear analysis of a single cylinder diesel engine biodiesel (B20) after 512 hours <br/> <br/>Authors: Bora, Dilip Kumar; Das, L M; Babu, M K G <br/> <br/>Abstract: This study presents effects of biodiesel blends namely B20K fuel (80% diesel + 20% Karanja biodiesel) on single cylinder diesel engine performance and lubricating oil under two long duration endurance tests of 512 h. SAE grade 15W 40 engine oil was used for both the tests. Experimental results indicated that engine can be safely operated with B20 fuel, without significant changes in engine power, fuel economy and lubricating oil properties. <br/> <br/>Page(s): 639-642 Thu, 29 Jul 2010 22:58:59 GMT http://nopr.niscair.res.in/handle/123456789/9976 Title: Experimental investigation on a solar tunnel drier for copra drying <br/> <br/>Authors: Ayyappan, S; Mayilsamy, K <br/> <br/>Abstract: A natural convection solar tunnel drier (STD) was developed for copra drying under meteorological conditions of Pollachi, India. STD reduced moisture content from 52.2% to 8% in 57 h under full load and 52 h under half load conditions. Drying in bottom tray was lower (2%) than that of top tray. Average efficiency of STD was estimated as 20%. Quality of copra obtained was good (84.66% Milling copra Grade 1) as compared to open sun drying (53%). <br/> <br/>Page(s): 635-638 Thu, 29 Jul 2010 22:58:59 GMT
