Eduction of Coherent Structures in a Numerically Simulated Plane Wake
Coherent structures (CS) are educed using a conditional sampling technique involving alignment of vorticity patches of largest size and strength; hence we educe dominant CS. A numerically simulated spatially e...

Loss of homogeneity in a suspension by kinematic action
SEPARATION of heavy particles from a fluid medium by centrifugal forces or by barodiffusion is well known1. For a homogeneous fluid mixture comprising a suspension of very fine particles (such as smoke in air), o...

Effect of simultaneous sodium oxalate and methionine feeding with and without Varuna (Crataeva nurvala hook & Frost) therapy on urolithogenesis in guinea pigs
The effect of sodium oxalate and methionine supplementation on stone-related constituents of urine was studied in 18 adult male guinea pigs. Their serum and tissue chemistry and histological changes in urinary...

Semi-leptonic charm baryon decays in the relativistic spectator quark model
We calculate the exclusive semi-leptonic charm baryon decays of the lowest lying charm baryon states into the ground state strangeness baryons using the covariant spectator quark model approach. We present res...

On heavy baryon decay form factors
We consider in detail the consequences of the heavy quark mass limit in the weak decay of 1/2+ heavy baryons to 1/2+ and 3/2+ heavy baryon final states. We also analyze heavy baryon to light baryon transitions as...

Large Scale Structures in Reacting Mixing Layers
The role of large-scale coherent structures in the enhancement of mixing and chemical reaction in turbulent free shear flows has been investigated by analyzing direct numerical simulations of temporally growin...

Reconnection of Two Antiparallel Vortex Tubes: A New Cascade Mechanism
Numerical simulations of two antiparallel vortices reveal a new and crucial mechanism, which accumulates the reconnected vortex lines into characteristic ‘bridges’. The simultaneous occurrence of viscous vorti...

Dynamics and Topology of Coherent Structures in a Plane Wake
We report results of the study of coherent structures (CS) using numerical simulations of the transition region of a compressible, (subsonic), spatially evolving wake behind a thick splitter plate at moderatel...

Predictive value of some biochemical indices in stone formers
Search is under way to develop reliable tests for the prediction of stone risk. Several indices and ratios on the basis of urinary excretions have been suggested. In the present study the applicability of some...

Contribution of Different Doses of Ascorbic Acid to Urinary Oxalate and its Influence on the Mineralization Process
We have evaluated the actual contribution of ascorbic acid (AA) to urinary oxalate excretion using disodium EDTA as preservative in 16 healthy control subjects (HC), 17 stone formers who had not had surgical t...

Subharmonic Resonance in a Shear Layer
The initiation, growth, interaction, breakdown and regeneration of coherent structures in turbulent shear flows are the manifestations of a hierarchy of flow instability mechanisms. After the initial roll up o...

Conic Rescue of Bezier Founts
Attractive and aesthetically satisfying founts are now widely conceivable when using high resolution laser printers. The outline of these founts have frequently been defined by Bezier splines. Pratt (1985) has...

Three-Dimensional Simulation of Taylor-Couette Flow
Flow of an incompressible, viscous fluid confined in the annulus between two concentric rotating cylinders constitutes a classical problem in modern fluid mechanics. Of particular interest are the flows that a...

The Dynamics of Vortex Rings in an Unbounded Domain
Vortex dynamics is of vital importance in turbulent flows such as jets, atmospheric convection and far-field wakes of aircraft, because these turbulent flows can indeed be viewed as a tangle of vortex filament...

Amino Acid Excretion in Urinary Calculous Disease
In more recent times, major stress has been placed on the role of inhibitors in urolithiasis. Most urines are supersaturated and high levels of stone promoters would induce spontaneous crystallization but for ...

Efficacy of Intrathecally Administered Natural Human Fibroblast Interferon as Treatment of Multiple Sclerosis
In 1981 we reported the results of an open, preliminary study of 20 patients suggesting that intrathecally (IT) administered natural human fibroblast interferon (IFN-B) reduced the neurologic exacerbations of ...
