Crucial to an understanding of the mechanism of cell replication is a knowledge of the manner in which intracellular and surface membranes develop between successive divisions . The application of zonal centrifugation to separate cells according to their size and hence their relative age (Warmsley and Pasternak, 1970) has enabled us to study the timing of these events by measuring changes in fo...

Abstract Variational principles and variationally consistent boundary conditions are derived for a system of double Rayleigh beams undergoing vibrations subject to axial loads. The elastic layer connecting the modelled as three-parameter nonlinear Winkler–Pasternak with Winkler having linear components Pasternak only component. forced freely vibrating beam using semi-inverse approach. Hamilton’...

The mucins of sheep colonic mucosa, like other epithelial secretions, are members of the group of 'neutral' niucosubstances (Werner, 1953; Kent, 1962). These characteristically contain L-fucose, D-galactose, N-acetylamino sugars and frequently sialic acids and mannose (Gottschalk, 1960). Their chemical structure and the nature of the sugarpeptide links involved have not yet been established. Pr...

in this paper, nonlinear vibration and instability response of an embedded pipe conveying viscose fluid is investigated. the pipe is considered as a timoshenko beam embedded on an elastic foundation which is simulated by spring constant of the winkler-model and the shear constant of the pasternak-model. the external flow force, acting on the beam in the direction of the flexural displacement is...

This paper presents a modified variational principle for the treatment of thin plate bending on an elastic foundation. The foundation may be of the Winkler or Pasternak type. A hybrid Trefftz (HT) finite-element (FE) model has been developed based on the principle and a new set of T-complete functions. The derivation of the new set of trial functions is based mainly on the resolution approach o...

Detailed displacements of [3H]dihydromorphine by ketocyclazocine and SKF 10,047, [3H]ethylketocyclazocine by SKF 10,047, and C3H]SKF 10,047 by ketocyclazocine are all multiphasic, suggesting multiple binding sites. After treating brain tissue in vitro with naloxazone, all displacements lose the initial inhibition of 3H-ligand binding by low concentrations of unlabeled drugs. Together with Scatc...

This paper is concerned with the surface and small scale effects on transverse vibration of a viscoelastic single-layered graphene sheet (SLGS) subjected to an in-plane magnetic field. The SLGS is surrounded by an elastic medium which is simulated as Visco-Pasternak foundation. In order to investigate the small scale effects, the nonlocal elasticity theory is employed due to its simplicity and ...
