چکیده: Background: Myocardial infarction is one of the most common types of cardiac diseases. Considering the necessity of self-care in these patients, continuous care model can be an appropriate framework for sensitizing patients to accept and continue health behaviors. Therefore, this study aimed to determine the effect of home-based continuous care model on the quality of life of patients wi...
predicting the maintenance and management costs and replacement age of tractors in agricultural mechanized units, is important from several points. so, doing a timely agricultural operations, more accurate measure of the amount of income including the cost of these items , determining the useful life of old tractors , replacement age, cost of the process changes and the possibility of examinin...
Abstract: Quality of life remains low for many patients after coronary heart surgery. The purpose of this study was to design and evaluate an educational program in the improvement of life quality in patients after coronary artery bypass graft (CABG) surgery. Materials and methods: In this experimental clinical-trial 110 patients were randomly devided into case and control groups six weeks afte...
سینتیک تخریب حرارتی خانواده ای ازپلیمرهای گرما سخت (پلی آمیدها) با استفاده از تکنیک tga ، در سه سرعت گرمادهی (0c min-1 20 و15 ،5/7) در اتمسفر نیتروژن بررسی شده است. روش های isoconversional (model – free) )از قبیل روش های فلاین، وال و ازاوا (fwo)، کیسینجر، آکاهیرا و سانوز(kas) و تانگ (tang) (و model – fitting (روش کوتس و ردفرن ((cr)استفاده شده اند تا سه تایی سینتیکی یعنی انرژی فعالسازی، فاکتو...
در این پژوهش نانو ذرات هیبریدی نانو لوله کربنی- اکسید روی سنتز و شناسایی شده¬است و نتایج آنالیز دستگاهی tem, sem و ft-ir تشکیل نانو ذره هیبریدی را تایید می¬نماید. اثر هیبرید سازی نانو لوله کربنی با اکسید¬ روی سرعت تخریب حرارتی یک ترموست بر پایه dgeba مورد بررسی قرار گرفت. مطالعات مقایسه¬ای نشان داد که سرعت تخریب با هیبرید سازی نانو ذرات کاهش می¬یابد و از روش زیر تبعیت می¬کند. rpure dgeba > r m...
Buckling restrained braced frames (BRBFs) for seismic load resistance have been widely used in recent years. One of the key requirements for a buckling restrained brace is to sustain large plastic deformations under severe ground motions. The core of a buckling restrained brace is prone to fatigue fracture under cyclic loading. The earthquake induced fracture type of the core plate in a bucklin...
abstract: in the paper of black and scholes (1973) a closed form solution for the price of a european option is derived . as extension to the black and scholes model with constant volatility, option pricing model with time varying volatility have been suggested within the frame work of generalized autoregressive conditional heteroskedasticity (garch) . these processes can explain a number of em...
