In this paper, the performance of an ejector cooling system and the effect of the following different working fluids such as water, ammonia, R134a, R141b, R12, R600 and R245fa are described and the effects of cycle parameters on the consumed heat and work and COP are studied. This cycle with the working fluid R141b has the least COP while the working fluid R₁₂ in comparison with the other worki...
The ejector is a process equipment frequently used in refrigeration processes. There currently knowledge gap on the efficiency of ejectors operating with mixtures. To address this gap, we present one-dimensional model for mixtures, defined by spatially distributed mass-, energy- and momentum-balances different zones, which together constitute full geometry. recently developed delayed homogeneou...
ERC/mesothelin is expressed in mesothelioma and other malignancies. The ERC/mesothelin gene (MSLN) encodes a 71-kDa precursor protein, which is cleaved to yield 31-kDa N-terminal (N-ERC/mesothelin) and 40-kDa C-terminal (C-ERC/mesothelin) proteins. N-ERC/mesothelin is a soluble protein and has been reported to be a diagnostic serum marker of mesothelioma and ovarian cancer. Gastric cancer tissu...
This paper describes an ejector model for the prediction of on-design performance under available conditions. is a direct method calculating optimal (entrainment ratio or ER) without need iterative methods, which have been conventionally used. The values three efficiencies used to account losses in are calculated by using systematic approach (by employing CFD analysis) rather than hit and trial...

BACKGROUND Patients with biliary obstruction are at high risk to develop septic complications after endoscopic retrograde cholangiography (ERC). We evaluated the benefits of local application of antimicrobial agents into ERC contrast media in preventing post-ERC infectious complications in a high-risk study population. METHODS Patients undergoing ERC at our tertiary referral center were retro...
