Title: Effect of Packaging on Quality and Shelf-life of Osmo-air Dried Apricot Authors: Sharma, K D; Kumar, Rajesh; Kaushal, B B Lal Abstract: Osmotically dehydrated apricot with a good consumer acceptability were developed and evaluated for their quality in different packages during storage at 13-28^oC. The critical point for the storage of osmo-air dehydrated apricot was at 60 per cent relative humidity with 12.5 per cent equilibrium moisture content (EMC) whereas the optimum equilibrium relative humidity (ERH) was found to be 48 per cent at 8.51 per cent EM C. The quality of dried fruit deteriorated significantly in polyethylene and glass jars during storage study of 6 months however, a minimum change in chemical composition and sensory attributes was observed in laminated pouches. At the same time laminated pouches were attractive and convenient to handle which is beneficial for distribution and from marketing point of view. Page(s): 949-954

Title: Supported Perovskites as Catalysts for CO Oxidation Authors: Chand, Shri; Sharma, A K; Garg, Anurag; Mishra, I M Abstract: Lanthanum and barium ferrites as well as lanthanum cobaltate binary oxidic species supported on alumina and zirconia were tested for their catalytic activity for the CO oxidation reaction. Synthesized perovskite oxides were supported on alumina or zirconia by dry impregnation. For the same percent loading of the perovskite (5 .8per cent), LaCoO₃ /ZrO₂ were found to be most active in comparison of La-Co-O solids supported on zirconia may be attributed to better reactivity of Co at B-site in comparison to Fe, homogeneous and higher dispersion on zirconia in comparison to alumina, ionic oxygen carrying capacity of zirconia and larger ionic size of Zr⁴⁺ ion.

Studies on Anaerobic Digestion of Distillery Waste and Methane Formation

Wed, 01 Nov 2000 00:00:00 GMT

Title: Studies on Anaerobic Digestion of Distillery Waste and Methane Formation Authors: Prakash, N B Abstract: Experiments were conducted on a laboratory scale by anaerobic digestion to treat distillery effluent with special reference to maximum BOD and COD removal, and for maximum methane formation. The BOD and COD removal ranged between 85-93 per cent under steady state conditions thereby indicating that the distillery effluent could be treated by anaerobic process. The bio-kinetic coefficients were evaluated to study the metabolic performance of the microorganisms. Maximum methane production was obtained with the use of calcium carbonate. Page(s): 940-943

Water-Based Couplants for General Purpose Use for Ultrasonic NDT Applications

Wed, 01 Nov 2000 00:00:00 GMT

Title: Water-Based Couplants for General Purpose Use for Ultrasonic NDT Applications Authors: Bindal, V N Abstract: A study on the newly developed couplant liquid and gel suitable for ultrasonic NDT inspection is reported. Results of the measurements of various physical parameters like viscosity, density, ultrasonic velocity, etc. which have direct influence on acoustic coupling, are reported. With the help of the measured ultrasonic velocity and the acoustic impedance of the newly developed couplants, the results have been discussed alongwith theoretical considerations. It is indicated that the newly developed couplants have better transmission coefficient and give 3 dB better coupling, as compared to the conventionally used liquids. These couplants offer many other advantages and have potential applications in industry. Page(s): 935-939
