  • Diffraction studies of rare-earth phosphate glasses 
    Shikerkar, A.G.; Desa, J.A.E.; Krishna, P.S.R.; Chitra, R. (Journal of Non-Crystalline Solids. 270(41642); 2000; 234-246.)
    A series of lanthanide oxides was incorporated in a vitreous phosphate host network. Molar constituents of the glasses were typically (La2O3)(10)(RxOy)(10)(Al2O3)(5)(P2O5)(75). Each glass had a different lanthanide (R atom) ...
  • Evaluation and performance enhancement of a pressure transducer under flows, waves, and a combination of plows and waves 
    Joseph, A.; Desa, J.A.E.; Foden, P.; Taylor, K.; McKeown, J.; Desa, E. (Journal of Atmospheric and Oceanic Technology. 17(3); 2000; 357-365.)
    The performance of a pressure transducer, with its inlet attached to differing hydromechanical front ends, has been evaluated in Row flume and wave flume experiments in which laminar and turbulent Rows, and regular progressive ...
  • Superconductivity suppression in (Er(1-x)Pr(x))Ba(2)Cu(4)O(8): An x-ray absorption spectroscopic study 
    Chhikara, A.; Priolkar, K.R.; Sarode, P.R.; Prabhu, R.B.; Narlikar, A.V. (Journal of Physics-Condensed Matter. 11(22); 1999; L229-L233.)
    In this letter we report our measurements of Er and PrL(3) edges in Er(1-x)Pr(x)Ba(2)Cu(4)O(8), 0 less than or equal to x less than or equal to 0.6. The normalized L(3)-edge intensity is seen to closely follow the behaviour ...
  • Evaluation of pressure transducers under turbid natural waters 
    Joseph, A.; Desa, E.S.; Desa, E.; Smith, D.; Peshwe, V.B.; Vijaykumar; Desa, J.A.E. (Journal of Atmospheric and Oceanic Technology. 16(8); 1999; 1150-1155.)
    Pressure measurements made in two turbid natural waters have led to the inference that the effective depth-mean in situ density values, rho(eff), of these waters are less than (approximate to 2.70 percent-6.5 percent) their ...
  • Statistical stationary states for a two-layer quasi-geostrophic system 
    Mesquita, S.B.; Prahalad, Y.S. (Proceedings of the Indian Academy of Sciences - Mathematical Sciences. 109(1); 1999; 107-115.)
    Existence of a family of locally invariant probability measures for large scale flows in enclosed temperate sea is proved. This model is extremely important for understanding the meso-scale phenomena in oceans. The techniques ...
  • Inelastic neutron scattering in CeSi(2-x)Ga(x) ferromagnetic Kondo lattice compounds 
    Priolkar, K.R.; Rao, M.N.; Prabhu, R.B.; Sarode, P.R.; Paranjpe, S.K.; Raj, P..; Sathyamoorthy, A.. (Journal of Physics-Condensed Matter. 10(47); 1998; 10557-10564.)
    An inelastic neutron scattering investigation of the ferromagnetic Kondo lattice compounds belonging to the CeSi(2-x)Ga(x) system that have x = 0.7, 1.0, and 1.3 is reported. In these compounds, the ground state is expected ...
  • Optical sensors in environmental monitoring 
    Choudhury, P.K. (Current Science. 74(9); 1998; 723-725.)
  • Spin dynamics of CeSi(2-x)Ga(x), 0.7 less than or equal to x less than or equal to 1.3 
    Priolkar, K.R.; Rao, M.N.; Prabhu, R.B.; Sarode, P.R.; Paranjpe, S.K.; Raj, P.; Sathyamoorthy, A. (Journal of Magnetism and Magnetic Materials. 185(3); 1998; 375-378.)
    In this paper we report inelastic neutron scattering experiments performed on CeSi(2-x)Ga(x), 0.7 less than or equal to x less than or equal to 1.3. The thermal evolution of quasielastic linewidth indicates a crossover ...
  • Competition between RKKY and Kondo interactions in CeSi(2-x)Ga(x) 
    Priolkar, K.R.; Prabhu, R.B.; Sarode, P.R.; Ganesan, V; Raj, P.; Sathyamoorthy, A. (Journal of Physics-Condensed Matter. 10(20); 1998; 4413-4422.)
    Electrical resistivity measurements on compounds belonging to CeSi(2-x)Ga(x) (0.7 less than or equal to x less than or equal to 1.3) have been performed. The samples in this concentration range show a smooth crossover from ...
  • Resistivity and thermopower of the antiferromagnetic system MnTexSe1-x 
    Prabhu, R.B.; Kamat-Dalal, V.N.; Desa, J.B.C.E.; Bhatia, S.N. (Solid State Communications. 104(9); 1997; 565-567.)
    Measurement of resistivity and thermopower on the antiferromagnetic system MnTexSe1-x are reported for various values of x. Magnon drag contribution to the thermopower was also detected and measured in all the cases. ...
