Blood flow is modeled as non-Newtonian micropolar fluid. The non-linear governing equations of continuum and momentum in the cylindrical coordinate are being discretized using a finite difference approach and have been solved iteratively ,through Crank-Nicolson method. The blood velocity distribution, volumetric flow rate and Resistance to blood flow at the stenosis throat are computed for vari...

Recent studies of the tunnelling through two opaque barriers claim that the transit time is independent of the barrier widths and of the separation distance between the barriers. We observe, in contrast, that if multiple reflections are allowed for correctly (infinite peaks) the transit time between the barriers appears exactly as expected. PACS. 03.65.Xp It is a well known result that the tunn...

Existence of fixed point in orthogonal metric spaces has been initiated recently by Eshaghi and et al. [On orthogonal sets and Banach fixed Point theorem, Fixed Point Theory, in press]. In this paper, we introduce the notion of the strongly orthogonal sets and prove a genuine generalization of Banach' fixed point theorem and Walter's theorem. Also, we give an example showing that our main theor...

HE general model proposed by JACOB and MONOD (1961) to explain the control of inducible and repressible enzymes in bacteria has received considerable support to date (AMES and MARTIN 1964). According to this hypothesis, the genetic elements controlling sequential biochemical reactions are clustered on a genetic map into units of regulation called operons. An operon consists of a group of struct...

Carbamazepine has recently been shown to have a vasopressin-like action and, like chlorpropamnide, to be effective in controlling polyuria in patients with diabetes insipidus (Hartman, 1972; Uhlich et al., 1972). In the case reported here carbamazepine, which was being given to a patient suffering from depression and psychogenic polydipsia, induced inappropriate secretion of antidiuretic hormon...
