Appropriate operation of protection system is one of the effective factors to have a desirable reliability in power systems, which vitally needs routine test of protection system. Precise determination of optimum routine test time interval (ORTTI) plays a vital role in predicting the maintenance costs of protection system. In the most previous studies, ORTTI has been determined while remote bac...

The aim of this study was to investigate the effect of a Graston massage session on pain and range of motion of the lumbar and hip regions in men with chronic low back pain. Materials and Methods: The present study was an experimental study with a pre-test-post-test design. Participants in this study were 56 men with chronic...
معادله حالت برپایه مولکولی نه فقط یک سری اطلاعات ترمودینامیکی پایه ای مانند پتانسیل شیمیایی یا فوگاسیته را که برای شبیه سازی تعادل های فازی مورد نیاز است، محاسبه می کنند، بلکه اجازه جداسازی و سنجش کمّی اثرات ساختار مولکولی و تاثیر خواص توده ای ماده بر روی رفتار فاز را نیز می دهد. مثال هایی از این تاثیرات مانند اندازه مولکول ها و شکل (مثلاً طول زنجیره)، انرژی تجمعی (مانند پیوند هیدروژنی) و انرژی ...
the narrow operating window between pore pressure and fracture pressure makes drilling difficult in some operations. a feasibility study of managed pressure drilling (mpd) is carried out on iran darquain oil field. the previous wells drilled in this field showed that mud returns were lost during drilling gadvan formation. the present work addresses this problem by means of surface back pressure...
Background and Objective: Regarding high prevalence of musculoskeletal disorders (MSDs) among bakery workers and due to lack of information concerning posture analyzing, this study was carried out to identify working postures precisely in order to revise their work stations. Materials and Methods: In this cross-sectional study 334 Araki bakery workers were randomly selected. The data was collec...
a lattice boltzmann method is applied to demonstrate the comparison results of simulating natural convection in an open end cavity using different hydrodynamic and thermal boundary conditions. the prandtl number in the present simulation is 0.71, rayleigh numbers are 104,105 and 106 and viscosities are selected 0.02 and 0.05. on-grid bounce-back method with first-order accuracy and non-slip met...
