  • NONISOTHERMAL KINETICS OF DEHYDRATION AND DECOMPOSITION OF NICKEL CHLORIDE HYDRATE 
    Kanungo, S.B.; Mishra, S.K. (Thermochimica Acta, 241, 1994: 171-189)
    The dehydration and decomposition behaviour of nickel chloride hydrate has been studied by a non-isothermal method with different experimental conditions such as heating rate, sample size, inert gas flow, etc. Kinetic ...
  • TRANSPORTATION OF COARSE COAL IN A FINE MEDIUM 
    Panda, D.; Parida, A.; Murty, J.S.; Mitra, A.K. (International Journal Of Multiphase Flow, 20(1), 1994: 171-177)
    Transportation of coarse coal, up to a size of 7 mm, in a fine-coal slurry medium with a particle size < 150 mum has been studied up to 58% by wt of the overall concentration in a 50 mm dia pipeline. A model has been ...
  • EFFECTS OF METALLIC AND D2EHPA IMPURITIES ON NICKEL ELECTROWINNING FROM AQUEOUS SULFATE BATHS 
    Kuzeci, E.; Kammel, R.; Gogia, S.K. (Journal Of Applied Electrochemistry, 24(8), 1994: 730-736)
    The presence of metallic and organic solvent impurities in pregnant electrolyte during hydrometallurgical processing causes problems in nickel electrowinning. To overcome these problems, a study on the combined effects of ...
  • BUBBLE-SIZE DISTRIBUTION IN A FLOTATION COLUMN 
    Biswal, S.K.; Reddy, P.S.R.; Bhaumik, S.K. (Canadian Journal Of Chemical Engineering, 72(1), 1994: 148-152)
    The bubbles that were generated in a flotation column were measured. The bubble size distributions were obtained both for air-water and air-water-coal systems. The size distribution pattern was fitted to different equations. ...
  • METHANE BUDGET FROM PADDY FIELDS IN INDIA 
    Parashar, D.C.; Mitra, A.P.; Gupta, P.K.; Rai, J.; Sharma, R.C.; Singh, N.; Kaul, S.; Lal, G.; Chaudhary, A.; Ray, H.S.; Das, S.N.; Parida, K.M.; Rao, S.B.; Kanungo, S.P.; Ramasami, T.; Nair, B.U.; Swamy, M.; Singh, G.; Gupta, S.K.; Singh, A.R.; Saikia, B.K.; Barua, A.K.S.; Pathak, M.G.; Iyer, C.S.P.; Gopalakrishnan, M.; Sane, P.V.; Singh, S.N.; Banerjee, R.; Sethunathan, N.; Adhya, T.K.; Rai, V.R.; Palit, P.; Saha, A.K.; Purkait, N.N.; Chaturvedi, G.S.; Sen, S.P.; Sen, M.; Sarkar, B.; Banik, A.; Subbaraya, B.H.; Lal, S.; Venkatramani, S.; Sinha, S.K. (Current Science, 66(12), 1994: 938-941)
    Earlier measurements(1) of methane emission from rice paddy fields yielded a low methane budget of around 3 Tg/yr for India, and was reported at IPCC forums(2). This low budget was based on limited data. An extensive ...
  • PHYSICOCHEMICAL PROPERTIES OF COPPER SUBSTITUTED LANTHANUM MANGANATE AND THEIR CATALYTIC ACTIVITY FOR H2O2 DECOMPOSITION AND CO OXIDATION 
    Das, N.N.; Parida, K.M.; Tripathy, B.C.; Rao, S.B. (Indian Journal Of Chemistry Section A-Inorganic Bio-Inorganic Physical Theoretical & Analytical Chemistry, 33(9), 1994: 820-825)
    A series of Cu substituted LaMnO3(LaMn1-xCuxO3, x = 0-0.8) have been prepared by different methods and characterised. Samples with lower values of x(x less than or equal to 0.06) show a single phase perovskite structure ...
  • RAPID CHROMITE DISSOLUTION USING A MANGANESE-DIOXIDE LITHIUM-SULFATE SULFURIC-ACID MIXTURE FOR MATRIX-INDEPENDENT DETERMINATION OF CHROMIUM 
    Chattopadhyay, P.; Mistry, M. (Analytica Chimica Acta, 295(3), 1994: 325-330)
    A mixture of manganese dioxide-lithium sulphate-sulphuric acid has been used for accurate and precise estimation of chromium in various chromite matrices. Inter-method comparison studies show that the proposed procedure ...
  • TRITERPENOIDS FROM THE RESIN OF SHOREA-ROBUSTA 
    Hota, R.K.; Bapuji, M. (Phytochemistry, 35(4), 1994: 1073-1074)
    From the resin of Shorea robusta, in addition to three known triterpenoids, a new nor-triterpene 3beta-acetoxy-28-nor-urs-12-ene has been isolated. The structure of the new triterpene was established by photochemical ...
  • DESIGNING AND SELECTING A COLLECTOR FOR OPTIMUM FIELD PERFORMANCE ON THE BASIS OF PRESSURE-AREA ISOTHERMS 
    Singh, B.P. (Langmuir, 10(2), 1994: 510-513)
    This investigation has been aimed at developing a method for characterizing and predicting the performance of collectors based on pressure-area isotherms. This procedure can be used both to choose the proper collector and ...
  • PARTIAL SIMULATION OF SMELTING REDUCTION PROCESS IN A PLASMA REACTOR 
    Galgali, R.K.; Mohanty, B.C.; Gumaste, J.L.; Dutta, P.; Ray, H.S.; Ray, A.K.; Agarwal, B.B.; Shivaramkrishna, N.; Roy, A.K.; Sabharwal, S.P.S.; Prasad, K.K. (Production Of Liquid Iron Using Coal, 1994: 259-271)
