Introduction: Ovarian cancer is caused by malignant changes in the cells of the ovary. In various studies, cancer has been regarded as a biological system that has a set of characteristics; therefore, presenting a model of this system can considerably help to study and predict the phenomena related to the growth and spread of cancer. This study attempted to model and simulate the growth and spr...
this paper examines the application of a gis based planning support system, what if? tm, to evaluate alternative growth policies for sustainable urban growth in a rapidly growing city of iran. the paper describes the study area, dorood city, and the what if? model. it then explains the procedures that were used to obtain the required data and to run the model to dorood city. the paper concludes...
abstract previous researches have shown success of growth hormones usage on flower production increase, pod and prevention of abscission of them in some of the pulses. two tests were done, in order to find out the effects of growth hormones to on flower production increase, pod and chick pea yield composites in farmer conditions (2010-11) and green house conditions as factorial on the proje...
Chemical Vapor Deposition (CVD) is one of the most important methods for producing Carbon Nanotubes (CNTs). In this research, a numerical model, based on finite volume method, is investigated. The applied method solves the conservation of mass, momentum, energy and species transport equations with aid of ideal gas law. Using this model, the growth rate and thickness uniformity of produced CNTs,...
The Impact of Social damages on the Effectiveness of Fiscal and Monetary Policies: The DSGE Approach
The purpose of this study is to investigate the effect of social damages (divorce, crime and addiction) on the effectiveness of fiscal and monetary policies. To achieve this, the literature on endogenous growth models has been used and the relationships of economic agents have been explained in the form of a dynamic stochastic general equilibrium model. In the designed DSGE model, labor produc...
Lactic acid production in a batch submerged fermentation process by five Lactobacilli: bulgaricus, casei, lactis, delbrueckii and fermentum in lactose fortified whey culture were investigated. Kinetic behavior of Lactobacilli growth rate and lactose utilization was studied based on the Moser and Gompertz kinetic models. Trendline tool in Excel software was applied for fitness assessment of the ...
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...
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...
The purpose of this study is to investigate the impact of exchange rate misalignment on inflation persistence. For this purpose, Vector Auto Regression method and Markov Switching model is used for quarterly data during 1989:4 -2014:3. The results show that, the impact of liquidity growth and exchange rate misalignment on inflation persistence is positive. On the other hand, GDP growth has a ne...
