Thermal instability in a horizontal layer of fluid, with the boundary temperatures modulated sinusoidally in time, is studied. The amplitude of modulation is assumed small and is used as an expansion parameter. It is shown that an exact solution can

The linear stability of two viscous electrically conducting quiescent fluids, separated by a plane interface, and permeated by a sheared magnetic field parallel to the interface is studied. An analytical study using a short-wavelength approximation s

Organic ligand with carboxyhydrazide functional group was immobilised on the surface of silica gel and the metal binding capacity of the ligand-embedded silica was investigated. The functional group was covalently bonded to the silica matrix through

The equilibrium and stability of a toroidal non-neutral plasma of low density has been studied numerically. The equilibrium is computed using the variational moment method, while linear stability is computed using a Fourier representation in the polo

The eigenvalue problem governing small amplitude electrostatic modes in a cylindrical column of non-neutral plasma is solved using a finite difference method. The eigenvalue problem is considered as a system of differential equations. A finite differ

The stability of a perfectly conducting fluid layer flowing along a magnetic field, parallel to a finitely conducting thin wall is examined. Finite layer width and compressibility of the fluid are shown to significantly lower the flow velocity requir

A finite difference method is developed and used to compute the diocotron spectrum (discrete plus continuum) of a non-neutral plasma column with an arbitrary profile of the number density. For step function density profiles the results agree with the

The effect of viscosity on the stability of a non-neutral plasma is studied. Stability boundaries are obtained for two-dimensional electrostatic perturbations of long wavelengths. It is shown that a configuration with a monotone decreasing number den

The present studies on ferromanganese nodules and encrustations from the Indian Ocean and a sediment from the Pacific ocean, were carried out to investigate the role of Mn and Fe in the uptaking of various trace elements from seawater. The Indian Oce

In a non-neutral plasma column of constant density it is shown that, for certain parameter values, an infinitely degenerate internal mode, which has no variation in the axial direction, can be stationary in the laboratory frame. However, this mode ca
