Restorative proctocolectomy with pelvic ileal reservoir is a weli accepted option for the surgical treatment of ulcerative colitis. Acute pouchitis is a common complication and resembles acute ulcerative colitis. Patients with ulcerative colitis carry Escherichia coli that adhere to epithelial cells and thus this study examined whether acute pouchitis is associated with the carriage of adhesive...
The article presents the research materials of pike perch r. Volga and Kuibyshev reservoir noted changes that have occurred in its population. Prior to creation conditions Middle Volga, male zander matured at age 5–6 years, females 6–7 years. In reservoir, becomes sexually mature 4–5 a small part it matures three. due ecological plasticity ability lay eggs wide temperature range, regardless lev...
The concept of majorisation is explored as a tool to characterize the performance quantum Otto engine in quasi-static regime. For working substance form spin arbitrary magnitude, yields necessary and sufficient condition for operation engine, provided canonical distribution medium at hot reservoir majorised by its cold reservoir. case spin-1/2 interacting with an via isotropic Heisenberg exchan...
پیشنهاد های زیادی توسط محققین برای کاهش انتشار دی اکسید کربن مطرح و اجرا شده است . یکی از بهترین روش ها، ذخیره سازی در ساختار های زمین شناختی زیر زمینی می باشد. ذخیره سازی وتزریق دی اکسید کربن در مخازن خالی نفت و گاز ، مخازن نفت و گاز برای eor و egr ،سفره های آب شور ، بستر های زغال سنگی و اقیانوس ها انجام می گیرد.کشور ایران دارای سازند های بزرگ نفتی و گازی می باشد.از این رو می توان از آن ها برا...
Distributed hydrological model can be divided into two parts, as runoff and the convergence. Runoff calculation is the basis of distributed hydrological model, its results will determine the accuracy of the simulation results directly. Rainfall is an important input of runoff calculation, thus its accuracy has special significance to runoff calculation. For most small watershed, now mainly rely...
Intraventricular rupture of craniopharyngioma cysts is an unusual event which is associated with a high risk of loculated or communicating hydrocephalus. A 75-year-old woman presented at the Emergency Department of our hospital with mental status deterioration due to chemical ventriculitis and acute hydrocephalus following the intraventricular rupture of a craniopharyngioma cyst. The patient wa...
This paper presents a new discretization scheme for linear elasticity models using only one degree of freedom per face corresponding to the normal component of the displacement. The scheme is based on a piecewise constant gradient construction and a discrete variational formulation for the displacement field. The tangential components of the displacement field are eliminated using a second orde...
The dam-reservoir system is divided into the near field modeled by the finite element method, and the far field modeled by the excellent high-order doubly asymptotic open boundary DAOB . Direct and partitioned coupled methods are developed for the analysis of dam-reservoir system. In the direct coupled method, a symmetric monolithic governing equation is formulated by incorporating the DAOB wit...
We consider a covolume method for a system of first order PDEs resulting from the mixed formulation of the variable-coefficient-matrix Poisson equation with the Neumann boundary condition. The system may be used to represent the Darcy law and the mass conservation law in anisotropic porous media flow. The velocity and pressure are approximated by the lowest order Raviart-Thomas space on rectang...
in this thesis, first the notion of weak mutual associativity (w.m.a.) and the necessary and sufficient condition for a $(l,gamma)$-associated hypersemigroup $(h, ast)$ derived from some family of $lesssim$-preordered semigroups to be a hypergroup, are given. second, by proving the fact that the concrete categories, semihypergroups and hypergroups have not free objects we will introduce t...
