  • Geothermometric and oxygen fugacity studies of Mayurbhanj basic igneous complex 
    Das, S.K.; Mukherji, S. (Journal Of The Geological Society Of India, 50(1), 1997: 31-39)
    The basic igneous complex of Mayurbhanj is a differentiated suite composed of harzburgite, gabbronorite, leucogabbronorite and anorthosite. EPMA of the coexisting oxides in the rock samples reveal that magnetite-ilmenite ...
  • Kinetics of copper extraction by LIX-84 
    Halder, M.K.; Chaudhury, G.R.; Das, R.P. (Transactions Of The Indian Institute Of Metals, 50(4), 1997: 229-233)
    The extraction kinetics of the Cu-LIX84 system was carried out in a Lewis type cell. The Cu extraction rate increased with increasing temperature, pH and initial metal ion concentration. The extraction rate also increased ...
  • Vernadite in Goriajhor manganese ores, Gangpur Group, India 
    Mohapatra, B.K.; Nayak, Bibhuranjan; Sahoo, R.K. (Journal Of The Geological Society Of India, 49(3), 1997: 331-336)
    Characteristics of vernadite in manganese ores from Gangpur Group of rocks, Goriajhor Formation, Sundargarh district, Orissa, have been described. This terrestrial vernadite is distinguished from delta-MnO2 in marine ...
  • Transition metal pillared clay .3. A para selective catalyst for nitration of chlorobenzene 
    Mishra, T.; Parida, K.M. (Journal Of Molecular Catalysis A-Chemical, 121(1), 1997: 91-96)
    Nitration of chlorobenzene has been studied at different temperatures using transition metal (Fe(III), Cr(III), Mn(III)) pillared clays as the catalysts. All the samples showed high para selectivity (up to 94%). The acid ...
  • Production and properties of L-asparaginase from Mucor species associated with a marine sponge (Spirastrella sp.) 
    Mohapatra, B.R.; Bapuji, M.; Banerjee, U.C. (Cytobios, 92(370-71), 1997: 165-173)
    The fungus Mucor sp. isolated from the marine sponge Spirastrella sp. produced extracellular L-asparaginase. The maximum L-asparaginase activity was found at 50 degrees C. The activation and deactivation energies of the ...
  • R-mode factor analysis and its implications on the geochemistry of Nishikhal manganese deposit, Raigada district, Orissa 
    Nayak, B.K.; Mohanty, Swati; Rajeev; Sahoo, R.K. (Journal Of The Geological Society Of India, 49(2), 1997: 133-144)
    Normalised major and trace element data of manganese ores From Nishikhal are processed by using R-mode factor analysis of correlation matrix. Twenty major and trace elemental variables are expressed in terms of 3 common ...
  • Antibacterial efficacy of Demospongiae against some marine microfoulers 
    Wilsanand, V.; Wagh, A.B.; Bapuji, M. (Cytobios, 92(368), 1997: 35-42)
    The antibacterial activities of five species of Demospongiae collected off the east coast of India were assayed against four dominant marine fouling bacterial strains isolated from the biofilm of fouled aluminium panels. ...
  • Removal and recycling of copper from aqueous solutions using treated Indian barks 
    Reddy, B.R.; Mirghaffari, N.; Gaballah, I. (Resources Conservation And Recycling, 21(4), 1997: 227-245)
    Removal of copper from aqueous solutions containing 100-1000 ppm, using different Indian bark species, was performed on laboratory scale. The percentage removal of metal ions depends on the solution pH, bark species and ...
  • A new method for predicting critical volumes of organic compounds 
    Sastri, S.R.S.; Mohanty, Swati; Rao, K.K. (Fluid Phase Equilibria, 129(1-2), 1997: 49-59)
    A new method based on atomic and structural contributions is proposed for estimating the critical volumes of organic liquids. The proposed method gives more accurate values compared with the methods of Lydersen, Joback and ...
  • Co-extraction and selective stripping of copper and nickel using LIX87QN 
    Sandhibigraha, A.; Sarma, P.V.R.B. (Hydrometallurgy, 45(1-2), 1997: 211-219)
    LIX87QN diluted with kerosene (mostly aliphatic) was used to co-extract copper and nickel from ammoniacal carbonate solutions. The influence of equilibrium pH and extractant concentration (in the organic phase) on coextraction ...
