Earlier risk assessment for acute coronary insufficiency has been done on the basis of logistic function and multiple regression analysis. Such an approach does not take into account the pathophysiological relationships ...

Experimental data show that under the influence of an electrical current or an electrical charge, sperm acrosomal regions swell, release enzymes and disintegrate. This effect can be mediated at low potential gradients. A ...

During intravenous infusion, even though the limb is immobilized the needle often punctures the vein and fluid accumulates subcutaneously. The infusion rate is also affected by total or partial blockage of the needle. None ...

A new approach to haemoglobinometry based on reflectance photometry using a pretreated cell strip is described. A disposable cell strip is designed to absorb a standardized volume of blood from a finger prick without any ...

A multiplane 3-D thigh model is considered. The current densities in various planes are obtained using the Laplace equation. Electrodes are placed both in the transverse and longitudinal direction. A method that provides ...

Results are reported of a study of the effect of chronic long-term stimulation of the ampullary isthmic junction on tubal functions and fertility in rabbits. Preliminary experiments show that a 6-V, 48-Hz, 1-ms pulse ...

An interesting and difficult problem in the area of distributed problem solving is that of detecting the termination of distributed programs soon after their assigned task is over. In a distributed environment, processes ...

An augmented binary (AB) tree architecture is proposed with a view to providing fault tolerance. This architecture is an augmentation of an n-level full binary tree with n redundant nodes and 2 n+3n-6 redundant links. The ...

The authors conduct a numerical analysis of optical fibers characterized by arbitrarily graded, cylindrically symmetric refractive index profiles by transforming them into equivalent planar profiles and using a matrix ...

We present a simple analytical method to study birefringence and polarization mode dispersion (PMD) of elliptic-core fibers with uniform or differential stress in the fiber cross section. The model takes account of both ...
