    New bromotyrosine derived secondary metabolites have been isolated from the marine sponge Psammaplysilla purpurea, and the structures assigned on the basis of spectroscopic analyses of their acetates 1a' and 1b'.
  • POLYMERS FROM RENEWABLE RESOURCES .3. THERMAL-ANALYSIS OF THE INTERPENETRATING POLYMER NETWORKS DERIVED FROM CASTOR-OIL, POLYURETHANE POLYACRYLATES 
    Pattnaik, T.; Nayak, P.L.; Lenka, S.; Mohanty, Swati; Rao, K.K. (Thermochimica Acta, 240, 1994: 235-246)
    A number of polyurethanes (PU) were synthesized by reacting castor oil with hexamethylene di-isocyanate and varying the NCO/OH ratio. All polyurethanes were reacted with acrylamide using EGDM cross-linker and benzoyl ...
  • 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. ...

(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 ...
