چکیده
which embodies Poiseuille's law of flow and a term which covers the cost of maintenance of blood volume, p is the fall in pressure in dynes/cm. ~, b is the cost of blood volume in ergs/cc, sec. (considered constant), vol is the volume, r is the radius of the section of artery, and 71 is the viscosity of whole blood (also taken as "constant"). At constant flow, f (that is, for any given steady state), and at constant length of arterial section, l, the total energy, E, is a minimum when:

Nonlocal elasticity theory for static torsion of the bi-directional functionally graded microtube under magnetic field
The microtubes are important structures in nano electromechanical system .in this study a nonlocal model is presented to investigate the static torsion behavior of microtubes made of bi-directional factionally graded material (BDFGM) subjected to a longitudinal magnetic field. Mechanical properties of BDFGM microtube varies in the radial and longitudinal direction according to an arbitrary func...
متن کاملThe Arterial Pattern of Terminal Branch of the Abdominal Aorta in the Male Persian Squirrel (Sciurus Anomalus)
Introduction: The Persian squirrel (Sciurus anomalus) is considered the only well-known species of the family Sciuridae in the Middle East. Since some people keep this squirrel as a domestic pet, their attendance at veterinary clinics is increasing. So far, no study has been conducted on the arterial supply of the pelvic cavity and limb in the squirrel. Hence, this research was performed to fil...
متن کاملThermoelastic Analysis of Rotating Thick Truncated Conical Shells Subjected to Non-Uniform Pressure
In the present work, a study of thermoelastic analysis of a rotating thick truncated conical shell subjected to the temperature gradient and non-uniform internal pressure is carried out. The formulation is based on first-order shear deformation theory (FSDT), which accounts for the transverse shear. The governing equations, derived using minimum total potential energy principle, are solved, usi...
متن کاملA Rare Variation in Branching Pattern of the Internal Iliac Artery: A Case Report
Internal iliac artery (IIA) shows frequent variations in its branching pattern. We saw variations in the branching pattern of right IIA in a male cadaver. The IIA divided into anterior and posterior divisions. The branches of the anterior division included umbilical artery, inferior vesical artery, obturator artery. The other branches arose from posterior trunk such as iliolumbar, lateral s...
متن کاملA Modification on Applied Element Method for Linear Analysis of Structures in the Range of Small and Large Deformations Based on Energy Concept
In this paper, the formulation of a modified applied element method for linear analysis of structures in the range of small and large deformations is expressed. To calculate deformations in the structure, the minimum total potential energy principle is used. This method estimates the linear behavior of the structure in the range of small and large deformations, with a very good accuracy and low...
