Objectives: The authors of this paper hypothesized that vibration stimulation applied by a vibratory orthosis improves balance in patients with Parkinson’s disease (PD). In this study we evaluate this hypothesis. Methods & Materials: Fourteen PD patients (12 male and 2 female) with mean age of 59.9±9.1 (±SD) years were participated in this cross- sectional study. Using Biodex balance system,...
maximizing economic earnings is the most common goal in cut-off grade optimization of open-pit mining operations. when this is the case, the price of the product has a critical effect on optimum value of cut-off grade. this paper investigates the relationship between optimum cut-off grade and price to maximize total cash flow and net percent value (npv) of operation. in order to visualize this ...
In the current research, the microstructural changes and corrosion behavior of two-layer Steel/Bronze sheets were investigated after the heat treatment of the explosive welding process. The heat treatment was performed at 600ºC for 16 hr. Dynamic potential polarization, electrochemical impedance spectroscopy, optical microscopy, and scanning electron microscopy analyses were used. Based on of t...
در این رساله، ما ثابت جفت شدگی رأس مزونی ds0dk را با استفاده از قانون جمعqcd سه-نقطه، برای دو حالت d و k off-shell، بدست می آوریم. مزون ds0 پهنای واپاشی کمی دارد. پهنای کم این مزون تعجب آور نیست، زیرا جرم آن کمتر از جرم آستانه سیستم dk می باشد. داشتن ثابت جفت شدگی رأس ds0dk ، مهم است، به این دلیل که پهنای واپاشی در این کانال،که مهمترین کانال است، می تواند پهنای کلی حالت را به ما بدهد. بنابراین ...
کنترل دقیق پارامترهای دخیل در سالن های پرورش قارچ می تواند یکی ازعوامل موثر در کاهش مصرف انرژی و یا حتی افزایش کمی و کیفی محصول باشد. در این پژوهش با استفاده از کنترل فازی و کنترل on/off مدلی برای کنترل دمای کمپوست، رطوبت نسبی داخل سالن و غلظت دی اکسیدکربن همچنین با استفاده از نرم افزار شبیه ساز متلب مدل سالن و تجهیزات کنترلی مانند هواساز، طراحی شد. برای طراحی مدل کنترلی یک سری داده برداری اولی...
background: surgical site infection is known as a common complication after cardiac surgery, and cefazolin is the best prophylactic antibiotic to prevent this complication. the goal of this study was to evaluate the effect of continuous and intermittent cefazolin for the prevention of superficial surgical site infection following off-pump coronary artery bypass (opcab). methods: this prospectiv...
there is limited literature on how to engage the rural women in agriculture and improve their contributions to household food security and income. this study aimed to contribute to literature on women engagement in agriculture through vegetable production using good agricultural practices. the empirical data used were drawn from technology demonstrations and experimentation, learning fields, an...
Background & Objective: Mild cognitive impairment (MCI) is a transient state between normal condition and dementia. Available data indicates that coronary artery diseases (CAD) may increase the risk of MCI. Hence, the early detection of MCI can prevent the progression of cognitive decline. Materials & Methods: A sample of 65 subjects with degrees of CAD was enrolled to the study. For cogniti...
this ethnographic case study research was carried out in a private school setting in the context of iran. the research tried to explore the analysis and identity construction of a group of learners and teachers along with the content analysis of books on the basis of four types of commodified, political, national and narrative identities. how english language learners and teachers in an informa...
