  • A study of the white lines associated with the rare-earth lii and liii absorption discontinuities in some oxides and tungstates 
    Vishnoi, A.D.; Sapre, V.B.; Mande, C. (Physica Status Solidi B-Basic Research. 161(2); 1990; 891-896.)
    The intensities are studied of the white lines associated with the L,, and LllI absorption discontinuities of the rare earth elements in their oxides RE sub(2)O sub(3) (RE = La, Ce, Pr, Nd, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb ...
  • A study of manganese oxides by EXAFS spectroscopy 
    Mande, C.; Deshpande, A.P. (Physica Status Solidi B-Basic Research. 158(2); 1990; 737-742.)
    The experimental data of the EXAFS associated with the K absorption discontinuity of manganese are analysed in four manganese oxides, viz. MnO, Mn3O4, Mn2O3 and MnO2 using the graphical method originally proposed by Lytle, ...
  • The universality of the Raman Effect 
    Pimpale, A.V.; Mande, C. (Physics Education (India). 6(4); 1990; 269-280.)
    In this article which is dedicated to the memory of Sir C. V. Raman and his scientific genius we would like to focus the attention of the scientific community on the universality of the Raman effect in all the ranges of ...
  • Computable error-estimates for Newton's iterations for refining invariant subspaces 
    Nair, M.T. (Indian Journal of Pure and Applied Mathematics. 21(12); 1990; 1049-1054.)
    Chatelin has established, under assumptions on the unknown invariant subspace, the quadratic convergence of Newton's iterative refinements. We modify the procedure in line with Demmel's suggestions and obtain a criterion ...
  • On a Volterra Stieltjes integral equation 
    Vaz, P.T.; Deo, S.G. (Journal of Applied Mathematics and Stochastic Analysis. 3(3); 1990; 177-191.)
    The paper deals with a study of linear Volterra integral equations involving Lebesgue-Stieltjes integrals in two independent variables. The authors prove an existence theorem using the Banach fixed-point principle. An ...
  • Eigenelements of perturbed operators 
    Limaye, B.V.; Nair, M.T. (Journal of the Australian Mathematical Society (Series A). 49(1); 1990; 138-148.)
    Let lambda(0) be a semisimple eigenvalue of an operator T(0). Let gamma(0) be a circle with centre lambda s(0) containing no other spectral value of T(0). Some lower bounds are obtained for the convergence radius of the ...
  • Magnetoresistance study of CeSi(2-x)Ga(x) 
    Priolkar, K.R.; Rawat, R.; Das, I.; Sarode, P.R.; Prabhu, R.B. (Solid State Physics (India), Ed. by: S.L. Chaplot, P.S.R. Krishna and T. Sakuntala. Narosa Publishing House, New Delhi. 44; 2002; 433-434.)
    Magnetoresistance measurements on CeSi(2-x),Ga(x), x = 0.7, 1.0 and 1.3 were carried out in the temperature range 3K-125K and in fields upto 80 kOe. The data gives a dear evidence of competition between Kondo and RKKY ...
  • सर्वांसाठी गणित: गणिती साक्षरता [Sarvansathi Ganit: Ganiti Saksharata (Mathematics for all)] 
    Deo, S.G. (Gomantak. (Jan); 1990)
  • Restructuring of PG education in Goa University 
    Deo, S.G. (University News. (Jun); 1990; Require pagination (from-to))
  • 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) ...
