at the present work, the effect of cold exhaust gas recirculation (egr) on combustion and pollution of a dual fuel engine has been investigated by cfd code fire. the turbulent flow within the combustion chamber is simulated using the k-ε turbulence model, which is modified for engine flows. “wave” and “eddy break up” models are employed to predict combustion and spray process. the calculations ...

we report the cases of two patients diagnosed with morgagni hernia who presented with nonspecific abdominal symptoms. both underwent laparoscopic surgery that used a dual-sided mesh, polyvinylidene fluoride (pvdf; dynamesh ipom®). the procedures were successful and both patients were discharged with no complications. there was no recurrence in 18 months of follow up. herein is the report of th...
هدف: اندازه گیری دقیق کایفوز پشتی ستون فقرات هم در روند ارزیابی بیماران و هم در سنجش اثر درمانهای مختلف از ارزش بالایی برخوردار است.dual digital inclinometer(ddi) به عنوان ابزاری که می تواند به صورت غیر تهاجمی مقدار زاویه کایفوز را اندازه گیری کند معرفی شده است. امابنا بر اطلاعات موجود تاکنون تنها یک مطالعه به بررسی اعتبار و تکرارپذیری این ابزار درکشورمان پرداخته است. لذا هدف از این مطالعه بررس...
objectives: this study aimed to compare elderly fallers and non fallers by balance test under dual tasks conditions. methods & materials: this study was a analyse-comparative study. subjects were chosen from three parks of tehran. subjects were 20 older adults with no history of falls (aged 72.60±5years) and 21 older adults with a history of 2 or more falls in the last one year (aged 74.50±6 ye...
In this paper, a simple dual-band dual-polarized aperture stacked patch antenna with double sided notch is presented. This antenna is suitable for operation in telecommunication base stations. One of the bands covers the GSM band, while the other covers both DCS and UMTS bands. The proposed antenna shows good port decoupling of less than -30dB for dual linear polarization over its operating ban...
Introduction: Women are interested in social roles along with their maternal role. According to mothers' role in parenting style, family functioning, and quality of life, we compared the parenting style, quality of life, and family function between dual career and single career families in Yazd City.

dual job holding is widespread in iran’s labor market, 18% of work force are holding second job in 1993, which increased to 19% in 2003. using a rich three years panel data-set of socioeconomic characteristics of iranian households, the article aims to examine the determinants of dual job holding across the individuals who have participated in the labor market. since the issue of dual job holdi...
in this paper, we give a necessary condition for function in l^2with its dual to generate a dual shearlet tight frame with respect to admissibility.
To tackle the problem with inexact, uncertainty and vague knowl- edge, constructive method is utilized to formulate lower and upper approx- imation sets. Rough set model over dual-universes in fuzzy approximation space is constructed. In this paper, we introduce the concept of rough set over dual-universes in fuzzy approximation space by means of cut set. Then, we discuss properties of rough se...
