In this study, effect of press pressure used in the production of silver electrodes on the life of zinc - silver oxide batteries was investigated. For this purpose, initially four Ag electrodes (positive plate) with composition of 95 wt% silver oxide, 4.9 wt% carbon powder and 0.1 wt% resin prepared by powder metallurgy method and the press pressures of 40, 60, 80 and 100 bar was applied. Then,...
in sheet metal forming processes, one-stage production of conical-cylindrical parts with high accuracy is very difficult due to wrinkling and rupturing. hydrodynamic deep drawing assisted by radial pressure is one of the most applicable procedures in sheet hydroforming process on the point of producing conical-cylindrical parts. in this paper, forming pressure path is investigated as one of the...
In this paper, for the first time, a comprehensive experimental study is performed on hydroforming process of metallic bellows. For this purpose, the effects of the main process parameters and their interactions on the characteristics of hydroformed metallic bellows are investigated using Response Surface Methodology (RSM). The selected parameters as input variables are internal pressure, die s...
abstract introduction: primary dysmenorrhea is common in women during reproductive age. objective: this study aimed to determine the effect of acupressure on sixth spleen point (sp6) on relief of primary dysmenorrhea. methods: this study is a clinical trial. students with primary dysmenorrheal living in dormitory were studied during three menstrual cycles. pain intensity was measured on the fir...
بررسی تاثیر دو مانور ثبات دهنده شکمی (گود کردن و سفت کردن شکم) با استفاده از pressure biofeedback روی میزان فعالیت بدست آمده از سیگنال الکترومیوگرافی عضلات اکستانسور ناحیه کمری ـ لگنی در حین انجام اکستنشن هیپ در وضعیت دمر در زنان سالم و مبتلا به کمردرد مزمن غیر اختصاصی.
Some new equations of state which are derived for dense fluids in recent years, namely the linear isotherm regularity (LIR), the dense system equation of state (DSEOS), Inm-Song-Mason equation of state (ISM), and a newly derived semi-emperical equation of state have been used to investigate the common intersection point of isobaric expansivity in αp dense fluids. We have shown that the accura...
Introduction: Angiography is an invasive diagnostic procedure in cardiovascular diseases. In some cases, before angiography, patients experience anxiety and increase in vital signs in response to sympathetic system activation. The aim of this study was to determine the effect of P6 acupressure point on physiological indexes in coronary angiography candidates. Method: In a randomize...
