A solution algorithm based on electromagnetism-like mechanism is employed to analyze tradeoff between expected total relevant cost and expected number of stockout occasion under probabilistic demand. Inventory decisions generated from MOEMO (multi-objective electromagnetism-like optimization) are not easily dominated by traditional methods, but also MOEMO tradeoff spread much wider than those of sequential and simultaneous methods. <br/> <br/>Page(s): 569-573 http://nopr.niscair.res.in/handle/123456789/1810 Title: Biosorption of Cu(II) by immobilized biomass of Bacillus cereus M¹₁₆ from aqueous solution <br/> <br/>Authors: Chatterjee, Abhijit; Ray, Lalitagauri <br/> <br/>Abstract: Biosorption of Cu(II) ion from aqueous solution was studied using Bacillus cereus M1 16 immobilized in calcium alginate and agar agar gel in batch mode. Uptake of metal was very fast initially and equilibrium was attained within 240 min. Sorption data conformed well to both Freundlich and Langmuir isotherm model. Highest Cu(II) uptake (87.32%) by selected biomass (3.09 g/l, dry wt) immobilized in 3% calcium alginate occurred at 30°C, 120 rpm when initial copper concentration was 50 mg/l. <br/> <br/>Page(s): 629-634 http://nopr.niscair.res.in/handle/123456789/1809 Title: Optimization of cultural conditions and their statistical interpretation for production of indole-3-acetic acid by Bacillus subtilis CM5 using cassava fibrous residue <br/> <br/>Authors: Swain, M R; Ray, R C <br/> <br/>Abstract: Bacillus subtilis CM5, isolated from culturable cow dung microflora, produced indole -3- acetic acid (IAA) in solid state fermentation of cassava (Manihot esculanta Crantz.) fibrous residue. Response surface methodology using a full factorial Central Composite Design evaluated effect of incubation period (6 days), initial medium pH (7.0) and moisture holding capacity (70%) on IAA production (23.5 μg/g dry substrate) by B. subtilis CM5. <br/> <br/>Page(s): 622-628 http://nopr.niscair.res.in/handle/123456789/1808 Title: Influence of oxidative and non-oxidative conditions on petroleum pitch properties <br/> <br/>Authors: Srivastava, Manoj; Singh, Ranvir; Kumar, Manoj; Agarwal, U C; Garg, M O <br/> <br/>Abstract: A series of pitches were prepared by thermal treatment of petroleum feedstock under oxidative and non-oxidative conditions at 350-450°C, to study transformation behavior of feed components. Influence of type of oxidizing gas and oxidizing agent on softening point (SP), coking value (CV), quinoline insolubles (QI) and toluene insolubles (TI) was studied. Rate of increase of SP of pitch has been found more in oxidative conditions than in non-oxidative conditions. Oxidative conditions may also lead to reduction in stabilization period for making carbon fibers and activated carbon spheres. Formation of TI/QI is more under air/oxygen purging as compared to nitrogen purging. <br/> <br/>Page(s): 616-621
