application of cogeneration systems based gas turbine for heat and power production is increasing. because of finite natural energy resources and increasing energy demand the cost effective design of energy systems is essential. cgam problem as a cogeneration system is considered here for analyzing. two new approaches are considered, first in thermodynamic model of gas turbine and cogeneration ...

Radionuclide shuntography is a safe and simple method to determine shunt patency and analyze changes in CSF (Cerebro-Spinal-Fluid) flow. We present a case of complicated CSF shunt, in which radioisotopic scan correctly identified disconnection of the shunt tubing system localizing the site of extravasation accurately. The findings were confirmed by surgery performed for correction of the ...

Introduction: Systems-Based Practice (SBP) is one of the sixcompetencies introduced by the ACGME for physicians toprovide high quality of care and also the most challenging of themin performance, training, and evaluation of medical students.This concept analysis clarifies the concept of SBP by identifyingits components to make it possible to differentiate it from othersimilar concepts. For prop...

In this paper, we use parametric form of fuzzy number and we converta fuzzy linear system to two linear system in crisp case. Conditions for the existence of a minimal solution to $mtimes n$ fuzzy linear equation systems are derived and a numerical procedure for calculating the minimal solution is designed. Numerical examples are presented to illustrate the proposed method.

pre-implant disease is an inflammatory process that affects the surrounding tissues of a functional osseointegrated implant. it is usually the result of a disequilibrium between the micro-flora and the defense system. this case reports a 57-year-old man with unusual bone loss around dental implants. this was an unusual case of peri-implantitis that occurred only in the implants on one side of t...

this paper deals with the use of transferring (tf) system in legal medicine and forensic serology. biased upon the clear for mal genetics and excellent typing of tf phenotypes, in case of rare tf variants, favorable results are obtained in disputed paternity. in the present case of disputed paternity, the child and the father exhibits b2 c type while the mother shows the type cc. but the father...
