    Bucoadhesive patches of Pentazocine (PZ) for unidirectional drug delivery were prepared by casting carboxy methyl cellulose (CMC) with glycerol or propylene glycol and CMC-hydroxy ethyl cellulose (HEC) with glycerol. In ...
  • Undercooling studies on dispersed bismuth droplets 
    Chaubey, S.; Singh, V.; Ramachandrarao, P. (Springer India, 987-11)
    In the zinc-bismuth system, a monotectic reaction occurs at 689 K and 0·6 at.% Bi composition. Rapid solidification of the as-cast monotectic alloy led to a micromorphology in which bismuth was uniformly and bimodally ...

  • Solar x-ray control of the ionospheric absorption measured by the sweep frequency method 
    Gupta, G.P. (Springer India, 1978-11)
    The ionospheric absorption data measured by the sweep frequency method have been compared with the solar x-ray data in the band of 1-8 A during quiet- and disturbed-sun conditions. The degree of solar x-ray control of ...
  • DEVELOPING AND FULLY DEVELOPED TURBULENT FLOW THROUGH ANNULI 
    R. P. SINGH; K. K. NIGAM; P. MISHRA (1980)
    Turbulent flow velocity profiles for the inner and outer flow regions of annuli are proposed. Theoretical expressions for friction factors and entrance region pressure drops are developed and are further extended to the ...
  • Friction factor for newton and non newtonian fluid flow in curved pipes 
    SINGH, R. P.; MISHR, P. (1980)
    The present work deals with the study of laminar and turbulent flow of Newtonian and non-Newtonian fluids flowing through helical and Archimedian spiral coils. By using a suitable viscosity expression corresponding to the ...
  • Further comments on the behavior of acceleration waves of arbitrary shape 
    Sharma, V.D.; Menon, V.V. (1980)
    Converging waves with nonzero initial critical amplitude are completely characterized. It is shown that for a converging wave a necessary and sufficient condition for the initial critical amplitude to be zero is that the ...
  • Study of microwave response of coal and sandstone samples 
    Singh, R.; Singh, R.P.; Singh, K.P. (Springer India, 1980-07)
    Detailed measurements of relative dielectric constant and loss tangent of coal and sandstone samples have been carried out in the X-band of microwave frequency range (8-10 GHz). The effect of moisture, saline and petrol ...
  • Characteristic wave fronts in magnetohydrodynamics 
    Menon, V.V.; Sharma, V.D. (1981-05)
    The influence of magnetic field on the process of steepening or flattening of the characteristic wave fronts in a plane and cylindrically symmetric motion of an ideal plasma is investigated. This aspect of the problem has ...
  • Approximating fixed points of some mappings 
    Bose, R.K.; Mukherjee, R.N. (1981-08)
    In a uniformly convex Banach space, Senter and Dotson, Jr., have given conditions under which certain types of iterates of a quasi-nonexpansive mapping converge to a fixed point of the mapping. Here we consider two types ...
  • On Steady Incompressible Three-Dimensional Hydromagnetic Flows 
    PRASAD, G.; SINGH, T. (1982-05-01)
    In this paper certain theorems of theoretical interest have been established with the help of the geometrical properties of Faraday's surface (which is spanned by the flow and field lines). These theorems shed light on ...

    SOM, TANMOY; MUKHERJEE, R. N. (1984-06)
    In J. Math. Anal. Appl. 61 (1977), 466–474, Leader has given a fixed point principle for an operator f: X → X, where X is a metric-space, based on conditional uniform equivalence of orbits. We generalize this principle for ...
