Treatment of limed fleshings with 0.1% H2O2 (1:10 v/v) followed by 0.2 HCl (1:10 w/v) solutions produced very little or no H2S. Delimed fleshings, mixed with 19.5% (v/w) Pediococcus acidolactici culture, 20% (w/w) sugar and 2% (w/w) common salt, on fermentation at 30±2°C yield silage (protein 7%, fat 8% and ash 3.6%), which can be used in animal feeds. Optimized conditions (enzyme, 1.5% v/w of Protex-6L; temp., 55°C; hydrolysis time, 180 min) for hydrolyzing delimed LFs were determined by RSM. LFs yield white hydrolysate (yield, 3.5%; nitrogen, 12.4%; and fat, 1.5% w/w), which can be used in aquaculture and animal feeds to supplement arginine, phenylalamine and tyrosine. <br/> <br/>Page(s): 1054-1063 http://nopr.niscair.res.in/handle/123456789/1353 Title: Studies on sorption and elution behaviour of dyes using titanium phosphonate <br/> <br/>Authors: Maheria, Kalpana; Chudasama, Uma <br/> <br/>Abstract: Titanium-hydroxyethylidene diphosphonate (TiHEDP), a novel hybrid ion exchange material of the class of tetravalent metal acid (tma) salt, has been synthesized by sol-gel method and characterized by elemental analysis (ICP-AES), thermal analysis (TG / DTA and DSC), FT-IR and X-ray diffraction studies. Chemical resistivity of the material in acids, bases and organic solvents has been assessed. Sorption behaviour of dyes, crystal violet (CV), rhodamine 6G (R6G), methylene blue (MB) and pink FG (PFG) towards TiHEDP has been studied, based on thermodynamic parameters evaluated and adsorption isotherms (Langmuir and Fruendlich). Breakthrough capacity and elution behaviour of dyes have also been studied. Sorption affinity of dyes towards TiHEDP is found to be MB>CV>R6G>PFG. <br/> <br/>Page(s): 1047-1053 http://nopr.niscair.res.in/handle/123456789/1352 Title: A new computational method for microwave drying of potato slabs <br/> <br/>Authors: Daghbandan, A; Najar, R; Haghi, A K <br/> <br/>Abstract: Experiments and generalized mathematical models have been used to evaluate impact of heat and mass transfer mode on microwave drying of potato. Evolution of temperature, moisture content as well as overall drying kinetics have been discussed with various internal and external physical parameters. New computational method can be used as a tool for microwave drying of potato slabs more efficiently. <br/> <br/>Page(s): 1041-1046 http://nopr.niscair.res.in/handle/123456789/1351 Title: Performance evaluation of direct injection diesel engine with blends of Thevetia peruviana seed oil and diesel <br/> <br/>Authors: Balusamy, T; Marappan, R <br/> <br/>Abstract: Methyl ester of Thevetia peruviana seed oil (TPSO), blended with diesel, has been tried in naturally aspirated single cylinder diesel engine at rated speed of 1500 rpm. The performance and emission parameters like, brake thermal efficiency, brake specific fuel consumption, CO, HC, NOx, CO₂, O₂, smoke and exhaust gas temperatures are measured, analyzed and compared with that of diesel. Engine performance with TPSO has been found comparable to that of diesel and CO, HC emissions are less but NOx and smoke are slightly higher than that of diesel. <br/> <br/>Page(s): 1035-1040
