In this study, parameters affecting on SPE of trance trance muconic acid (t,t-MA), including sample pH, sample concentration, sample volume, sample flow rate, washing solvent, elution solvent, and type of sorbent were evaluated. After sample preparation of muconic acid as urinary metabolite of benzene, it was determined by HPLC-UV. In chromatographic analysis, column was C18 (250 cm × 4.6 mm id...
Abstract Introduction: Yoga as an exercise to improve the physical, psychological, social health condition, and promote the feeling of health in healthy people in the medical education community is considered. The aim of this research was to find The Effect of 8 Weeks Yoga Training on Respiratory Function and Heart Rate of Non-Athlete Females. Methods: 30 students of khorasgan Azad Universi...
this paper introduces a mesh generating algorithm for solving the traffic flow equation as a conservation law equation. the idea behind the new method is to use the characteristic curves and moving non-oscillatory finite volume method. in addition, when characteristic curves intersect, the proposed scheme uses shock speed equation in order to improve computational efficiency. we also compare...
In the present research, the laminar forced convective heat transfer and fluid flow characteristics for Al2O3-water nanofluid flowing in different bend (i.e., 180o and 90o) pipes have been investigated numerically in a three-dimensional computational domain using the finite volume technique. The effects of different pertinent parameters, such as the Reynolds number of the duct, volume fraction ...
Introduction: Nowadays, many modern industries require an environment with no contamination by particles and bacteria. An enclosed clean room environment is a place where parameters such as airborne particles, temperature, humidity, air pressure and air flow pattern is controlled. The aim of this study was to evaluate functional parameters of a clean room in a selected pharmaceutical industry....
Measuring the volume of a bubble, especially at its detachment, is a basic subject in gas-liquid two-phase flow research. A new indirect method for this measurement under constant flow conditions is presented. An electronic device is designed and constructed based on laser beam intensity. This device calculates the frequency of the bubble formation by measuring the total time of the formation p...
