Hot flash is among the most common complaints of menopausal women, affecting their career, social activities and quality of life. This study aimed to investigate the effects of Valerian on hot flashes in menopausal women. In this double blind clinical trial, 68 menopausal women with the chief complaint of hot flash were enrolled using sampling at hand and were randomly divided into drug and pla...
هدف از انجام این پژوهش مطالعه اثر ضد دردی مورفین و آمی تریپتین بر روی درد نوروپاتی حاصل از گره زدن عصب سیاتیک می باشد. جهت انجام این تحقیق با استفاده از نخ جراحی chromic gutبه شماره 4.0 چهار گره به فواصل 1میلی متری از یکدیگر بر روی عصب سیاتیک پای چپ حیوان زده شد. و پس از آن آستانه درد حرارتی در روزهای چهارم و هشتم، دوازدهم، شانزدهم، و بیستم بوسیله hot plate مورد اندازه گیری قرار گرفت .جهت بررسی...
the flow stress of steel depends significantly on microstructural changes taken place during hot deformation processes. in hot deformation processes, the flow stress of steel is influenced by two main metallurgical phenomena, i.e. recovery and recrystallization, along with its chemical composition and thermo-mechanical parameters. the final mechanical properties of steel are also determined by ...
In this research, the hot deformation behavior of W360 tool steel was investigated using hot compression test at 1000-1200°C and strain rates of 0.001, 0.01, 0.1, and 1 s-1. According to the results, dynamic recrystallization was found the most important restoration factor of this alloy during hot deformation. Recrystallization was enhanced with an increase in temperature and strain rate. Also,...
The aim of this study was to investigate the suitable temperature range for hot deformation of three medium carbon Ni-Cr-Mo low alloy steels by hot tensile and hot torsion tests. Hot tensile tests were carried out in the te,prature range of 850-1150°C at a constant strain rate of 0.1 s-1 until fracture. Then, the tensile flow behavior, hot ductility and microstructural evolution of the steels w...
background and aims: one of the most common approach to understanding spatial and temporal trends of event data is to break it up into a series of time snapshots. therefore space-time cube method applied in order to portray the likely trend in occurrence of the pulmonary tuberculosis (tb) cases. methods: in this study, information of all patients with pulmonary tb recorded in surveillance syste...
Background: Hot flash is a common problem in climactric (time course around menopause)and menopausal period. The most effective treatment of it is HRT but There is a serious need for alternative therapies for hot flashes, as hormone replacement therapy (HRT) is associated with increased rates of breast cancer and heart disease. Materials and Methods: This trial used a randomized, two-stage(...
introduction climate is a system consisting of atmosphere, lithosphere, cryosphere, hydrosphere, and biosphere. this system is involved in the exchange of energy and moisture among these five components. the exchanges link the atmosphere as the central component of the climate to other spheres. changes do not occur separately in this system; rather change in one component contributes to reactio...

The main objective of this project was to investigate the behavior and the damaging effects of hot tear segregations in the continuously cast steel blooms on the final product quality. To achieve this aim, plant data from three different types of steels were used. Investigations using the scanning electron microscope (SEM) equipped with energy dispersive x-ray spectroscopy (EDS) probe and metal...
