Nanofluids are stable suspensions of nanoparticles in conventional heat transfer fluids (base fluids) that exhibit better thermal characteristics compared to those of the base fluids. It is important to clarify various aspects of nanofluids behavior. In order to identify the thermal and hydrodynamic behavior of nanofluids flowing through non-circular ducts, in the present study the laminar flow...

mirizzi’s syndrome is a rare complication of gallstone disease , that gallbladder lumen can lie alongside the common hepatic duct, resulting in inflamation and resultan bile duct stricture . most cases are not indentified preoperatively. variations of the cystic duct and its point of :union: with the common hepatic duct are surgically important . here, we present an unusual case of type i miriz...

thoracic duct is a duct that drains the lymph from the cisterna chily into the venous angle of the cranial vena vava. thoracic duct in the horse is situated on the right side, but in rare cases the left thoracic duct has been reported. in this report the course and left position of the thoracic duct in an embalmed donkey is described. regarding many anatomical similarities between horse and don...

Anatomic variations in forensic extrahepatic bile ducts is common. Knowledge of extrahepatic bile duct variations is important for surgeons in order to prevent iatrogenic damage during surgery. This study aims to determine the variations in extrahepatic bile ducts among 150 cadavers located at the Kerman Medicine Organization. We performed autopsies on 150 cadavers. Bile ducts were exposed an...

in this paper, we investigate the existence of a positive solution of fully fuzzy linear equation systems. this paper mainly to discuss a new decomposition of a nonsingular fuzzy matrix, the symmetric times triangular (st) decomposition. by this decomposition, every nonsingular fuzzy matrix can be represented as a product of a fuzzy symmetric matrix s and a fuzzy triangular matrix t.

jahanshahloo has suggested a method for the solving linear programming problems with zero-one variables‎. ‎in this paper we formulate fully fuzzy linear programming problems with zero-one variables and a method for solving these problems is presented using the ranking function and also the branch and bound method along with an example is presented.

background : the application of ventilation systems in industries and workplaces is with the aim of improving environmental conditions for employees. the lack of appropriate ventilation system components design and control methods result in the production of sound and vibration in most components. the purpose of this study was to determine the role of the pad isolator in controlling vibration a...

A fast synthetic type iterative model is proposed to speed up the slow convergence of discrete velocity algorithms for solving linear kinetic equations on triangular lattices. The efficiency of the scheme is verified both theoretically by a discrete Fourier stability analysis and computationally by solving a rarefied gas flow problem. The stability analysis of the discrete kinetic equations yie...
