Adsorption capacities followed: Carbamazepine> Sulfamethoxazole> Propyphenazone. Lewatit VP OC 1163 showed a larger adsorption for pharmaceuticals having low solubility, with Freundlich adsorption parameter, K_f, reaching 46.068 [(mgg^-1) (mgl^-1)] for Carbamazepine (solubility, 179 mgl^-1). SAC₂₅₄ (Spectral Absorption Coefficient at 254 nm) can be used as a control parameter for pharmaceutical adsorption studies. <br/> <br/>Page(s): 417-425 Tue, 28 Apr 2009 22:58:59 GMT http://nopr.niscair.res.in/handle/123456789/3794 Title: Experimental study for improving energy efficiency of charcoal stove <br/> <br/>Authors: Kshirsagar, Milind Prakash <br/> <br/>Abstract: This paper describes design steps with experiments carried out for charcoal stove (SEES) to interlink efficiency and various design parameters. Important parameters affecting energy efficiency are amount of air supplied (flue gas temp.), retention time of flue gas in stove, insulation and skirt gap. Skirt gap is most important parameter for higher efficiency of SEES prototype. <br/> <br/>Page(s): 412-416 Tue, 28 Apr 2009 22:58:59 GMT http://nopr.niscair.res.in/handle/123456789/3793 Title: Biodesulphurization of natural gas in a three-phase fluidized bed bioreactor using Thiobacillus dentrificans <br/> <br/>Authors: Raju, H Prasad; Hossain, Sk Masud; Anatharaman, N; Das, Manas <br/> <br/>Abstract: Natural gas from well head contain a number of undesirable components including hydrogen sulphide (H₂S), which can be removed by anaerobic desulphurization process using three-phase fluidized bed bioreactor. Optimum H₂S removal (90.89%, w/w) was obtained at following parameters: H₂S conc., 0. 55 ì M /l; loading rate, 6.05 ì M /min; contact time, 12 h; pH, 7.0; temperature, 45°C and feed and culture flow rate, 11 l/ min. Methane (CH₄) gas of natural gas acts as a sole carbon source to bacteria and maximum bacterial growth is observed as 9.93 ´ 10⁸ numbers of cells/ml. <br/> <br/>Page(s): 406-411 Tue, 28 Apr 2009 22:58:59 GMT http://nopr.niscair.res.in/handle/123456789/3792 Title: High efficiency alcohol tolerant Saccharomyces isolates of Phoenix dactylifera for bioconversion of sugarcane juice into bioethano <br/> <br/>Authors: Gupta, Nidhi; Dubey, Ashutosh; Tewari, Lakshmi <br/> <br/>Abstract: Various indigenous strains of Saccharomyces sp. (SCP-1, SCP-3, SCP-4, SCP-5, SCP-7) isolated from datepalm (Phoenix dactylifera) sap were evaluated for alcohol dehydrogenase (ADH) enzyme activity, ethanol production and alcohol tolerance limits and compared with standard culture of S. cerevisiae (S.C.Std). Alcoholic contents in juice samples fermented with different yeast strains varied considerably (8.9-12.5%, v/v) as determined by GLC. Yeast cultures showed varied in vitro ethanol tolerance (3-12%). Isolate SCP-1 was found superior showing 12.5% ethanol production, high ADH enzyme activity (4.38 units/ml) and higher alcohol tolerance maintaining cell viability at 12% ethanol in YPD medium up to 48 h <br/> <br/>Page(s): 401-405 Tue, 28 Apr 2009 22:58:59 GMT
