One of the world's major mineral dust source regions lies along the border between Iran and Afghanistan. In this studyit is hypothesized that a low-level jet may play in role in generating the intensity of this source region. The presence of alow-level jet east of the Seistan mountains is documented here for the first time. The jet exists mainly from May toSeptember and has a core at 850 mb. Ma...
Numerous investigations have been devoted towards understanding the hydrodynamics of gas jets in fluidized beds. However, most of them address the problem from macroscopic point of view, which does not reveal the true behavior in the jet region at the single particle level. The present work aims to understand the jet behavior from a more fundamental level, i.e. the individual particle leve...
A numerical study has been carried out for slot air jet impingement cooling of horizontal concentric circular cylinders. The slot air jet is situated at the symmetry line of a horizontal cylinder along the gravity vector and impinges on the bottom of the outer cylinder which is designated as θ=0°. The outer cylinder is partially opened at the top with a width of W=30mm and is kept at constant t...
در این پایان نا مه ا بتدا به شرح مختصری درباره توابع ترکش و خصوصیات حالات نهایی هادرونی در نابودی الکترون- پوزیترون می پردازیم. یکی از مدل های هادرونی تحلیلی به نام مدل پراکندگی را معرفی کرده ، به روابط ریاضی این مدل اشاره خواهیم کرد. سپس با استفاده از برازش داده های تجربی به مقایسه میان پیش بینی های اختلالی qcd و مدل پراکندگی خواهیم پرداخت.متداول ترین متغیرهای شکل رویداد وابسته به رویدادهای سه...
In this paper, a control system is designed for automatic car turning. At first, the necessary information of car turning that were collected from the traffic bylaw, car driving training centers and traffic police are explained. Then, car turning is studied experimentally on several streets with different widths. Afterward, a proper path is designed for the automatic car turning system consider...
Background and Aim: Autotoxic substances such as JP-4 jet fuel can have negative effects on the auditory system by the various means such as cochlear dysfunction. The purpose of this study was to investigate the combined effects of exposure to JP-4 jet fuel and noise on hearing loss in rats, to determine the possible interference effects of these two risk factors on rat auditory system. Methods...
