Introduction: The cell cycle network is responsible of control, growth and proliferation of cells. The relationship between the cell cycle network and cancer emergence, and the complex reciprocal interactions between genes/proteins calls for computational models to analyze this regulatory network. Ample experimental data confirm the existence of random behaviors in the interactions between gene...
Energy shortage is one of the fundamental challenges of human beings in which finding a new way for optimum utilization of unique energy resources and cogeneration can be terminated to the reservation of energy or cogeneration purposes. In this paper, by using the combined Ejector Refrigeration Cycle (ERC) and Organic Rankine Cycle (ORC), in addition to producing power from Organic Rankine Cycl...
Since ordinary gas turbine cycles in actual condition comprise simple cycle, regenerative cycle, reheat cycle and intercooler cycle between high pressure and low pressure compressors, these cycles include 16 combined cycles by combining with a Rankine cycle that consists of three organic fluids and steam. In the present work, the thermodynamic analysis of the above combined cycles with three or...
In this research, Magneto-Hydro-Dynamic subsonic flow in a MHD generator has been simulated and its effect on efficiency and power generation of a triple cycle has been investigated. A 2D constant cross-section Faraday channel with segmented electrodes was used as MHD generator. MHD flow was assumed steady and compressible with ideal five-wave model MHD equations. Navier-Stokes equations were ...
Introduction: Estrogen and progesterone are supposed to modify pain sensitivity. However, the actual role of each of these steroid hormones in this respect is not well known. Plasma concentrations of these hormones show variation during estrous cycle. The role of alpha2 receptors in tonic pain has been pointed out. The aim of the present study was to investigate the agonist and antagonist effec...
When the degree of saturation at intersection approaches one, Webster’s optimum cycle length equation becomes inapplicable, because the cycle length will becomes very big when the degree of saturation approaches one and will be fully unrealistic when the degree of saturation becomes greater than one. This is not a problem for HCM2000 method. But optimum cycle length calculation in this method h...

مقدمه: سرطان کولورکتال، سومین سرطان منجر به مرگ در کشورهای غربی است. سن بالا، رژیم غذایی نامناسب، چاقی، بی تحرکی و تغییرات ژنتیکی از جمله فاکتورهای خطر این سرطان می باشد. بررسی ارتباط تغییرات ژنتیکی در سیستم های ترمیمی dna با سرطان زمینه ی بسیاری از تحقیقات اخیر است. در این مطالعه به بررسی ارتباط موارد پلی مورفیسم t241 m در ژن xrcc3 با سرطان کولورکتال پرداختیم. روش ها: در این مطالعه ی مورد- شاه...
The occurrence of cycle slips is a major limiting factor for achievement of sub-decimeter accuracy in positioning with GPS (Global Positioning System). In the past, several authors introduced a method based on different combinations of GPS data together with Kalman filter to solve the problem of the cycle slips. In this paper the same philosophy is used but with discrete wavelet transforms. For...
