  • Photoluminescence of Gd3+ ion in La(OH)(3) 
    Sakthivel, R.; Acharya, B.S. (Indian Journal Of Pure & Applied Physics, 37(3), 1999: 219-223)
    Photoluminescence spectra of La(OH)(3) and La(OH)(3) doped with different amounts of Gd3+ ions have been investigated. Pure La(OH)(3) is found to be non-luminescent whereas La(OH)(3) doped with Gd3+ becomes luminescent ...
  • A process for developing continuous casting mould-powder for steel industries 
    Mazumder, B. (Journal Of Scientific & Industrial Research, 58(10), 1999: 773-780)
    For selecting the right material for continuous casting mould-powder for steel industries, the importance of property-composition relationship of a mould-powder is outlined. The chemical composition of three varieties of ...
  • Effect of alcohol extracts of demospongiae on growth of periphytic diatoms 
    Wilsanand, V.; Wagh, A.B.; Bapuji, M. (Indian Journal Of Marine Sciences, 28(3), 1999: 274-279)
    Antifouling potentialities of alcohol extracts of demospongiae, collected off east coast of India, against four dominant marine fouling diatoms are reported. Of the 20 combinations worked out (5 sponges x 4 diatoms) ...
  • Viscosity and density of ternary mixture of di-(2-ethylhexyl)phosphoric acid (DEHPA)-benzene-toluene 
    Swain, N.; Chakravortty, V.; Singh, S.K.; Panda, D. (Indian Journal Of Chemistry Section A-Inorganic Bio-Inorganic Physical Theoretical & Analytical Chemistry, 38(11), 1999: 1116-1122)
    Viscosities and densities of the ternary liquid mixtures of di (2-ethylhexyl) phosphoric acid + benzene + toluene have been measured at 30, 35, 40 and 45 degrees C. The mixture viscosity, eta(m), is fitted to a Redlich-Kister-type ...
  • Surface properties of Indian hematite and bauxite and their coating mechanism with colloidal magnetite 
    Prakash, S.; Das, B.; Venugopal, R. (Journal Of Scientific & Industrial Research, 58(6), 1999: 436-442)
    The selective coating of colloidal magnetite on hematite and bauxite for enhancing the magnetic separation techniques which depends on surface and chemical phenomena is studied. The mechanism of colloidal magnetite interaction ...
  • Vanadium sludge - An useful byproduct of alumina plant 
    Rajeev; Pradhan, J.; Das, S.N.; Thakur, R.S. (Journal Of Scientific & Industrial Research, 58(12), 1999: 948-953)
    During the production of alumina from bauxite by the Bayer's process, a sludge containing fairly higher quantity of vanadium is obtained. Various workers have used different methods to recover vanadium from the sludge. ...
  • Evaluation of the influence of various physico-chemical parameters on coastal water quality, around Orissa, by factor analysis 
    Panigrahy, P.K.; Das, J.; Das, S.N.; Sahoo, R.K. (Indian Journal Of Marine Sciences, 28(4), 1999: 360-364)
    Physico-chemical parameters such as salinity, pH, DO, BOD, chlorophyll-a, nutrients (NO2-N, NO3-N, NO3-N, NH4N, PO4-P, total phosphorus) and major ions (Ca2+, Mg2+, F-) were studied during February-March, 1994 in the coastal ...
  • Antifouling activities of marine sedentary invertebrates on some macrofoulers 
    Wilsanand, V.; Wagh, A.B.; Bapuji, M. (Indian Journal Of Marine Sciences, 28(3), 1999: 280-284)
    Antifouling activities of alcohol extracts from four gorgonian species (Melitodes sp., Gorgonella sanguinolenta, Echinogorgia complexa, Acanthogorgia turgida), five soft corals [Dendronephthya sp. 1, Dendronephthya sp. 2, ...
  • Reduction of silica from complex calcite ore for use in seawater magnesia production 
    Rao, G.V.; Biswal, S.K.; Sastri, S.R.S.; Bhaumik, S.K.; Sengupta, D.K. (Minerals & Metallurgical Processing, 16(2), 1999: 56-60)
    The amenability of a calcite-bearing ore to the reduction of silica to below 0.2% by physical beneficiation was studied. The objective was to use the are as a raw material for seawater magnesia production. The ore contains ...
  • Factors affecting bioleaching kinetics of sulfide ores using acidophilic micro-organisms 
    Das, T.; Ayyappan, S.; Chaudhury, G.R. (Biometals, 12(1), 1999: 1-10)
    Recovery of metal values from sulfide ores by use of acidophilic microorganisms is gaining importance. A number of commercial/pilot plants are setup to find out the techno-economic feasibility of the overall process. The ...
