Abstract One of the essential issues in quality management water resources is determination level eutrophication and dissolved oxygen dam reservoirs other bodies. It possible to study changes concentration using qualitative models. In this study, CE-QUAL-W2, a two-dimensional model hydrodynamics capable predicting behavior aquatic ecosystems, has been used simulate eutrophication. As case Yamch...

PURPOSE The purpose of this study is to explore the influence of segmentation of the upstream and downstream parent artery and hemodynamic boundary conditions (BCs) on the evaluated hemodynamic factors for the computational fluid dynamics (CFD) analysis of intracranial aneurysms. MATERIALS AND METHODS Three dimensional patient-specific aneurysm models were analyzed by applying various combina...

___________ _ A technique of supporting a patient with perioperative right ventricular failure has been developed and used clinically. The method is simple, inexpensive, effective, and involves only conventional cardiopulmonary bypass equipment. Introduction ____________ _ Right ventricular (RV) failure can account for significant patient morbidity during cardiac surgery, especially when the RV...

Twisted atrioventricular connections occur almost exclusively in the hearts with biventricular atrioventricular connections. Only one example of double inlet left ventricle has been illustrated in which the axes of the two atrioventricular valves crossed each other. We describe herein three patients, and one autopsied specimen, with double inlet right ventricle in which magnetic resonance imagi...

Due to the limitation of water renewable resources on one hand and increasing growth in consuming different parts such as agriculture, industry, urban, environment other hand, face management these valuable many challenges. Present study attempts clarify recent condition problem introduce effective tools supply sector. In order achieve this purpose, simulating model HEC-Res Sim was used for Dok...

Persemaian Permanen Darmaga didirikan dalam rangka menyediakan kualitas bibit yang baik untuk rehabilitasi hutan dan lahan. Pada musim kemarau, penanaman tidak bisa dilakukan karena ketersediaan air terbatas, oleh sebab itu perlu alternatif penyediaan dapat disuplai secara kontinyu. Penelitian ini bertujuan merancang reservoir penampungan irigasi. Dalam perancangan, digunakan data iklim terdiri...

The prevalence of heterotopic gastric mucosa of the upper esophagus (inlet patch) has a wide range depending on the method and detail of examination. The inlet patch is believed to be a congenital malformation that rarely leads to symptoms. We aimed to quantify the prevalence of the inlet patch in a non-referred population and determine if there are any risk factors or associated symptoms. Men ...

Computational fluid dynamics (CFD) is potentially a valuable tool for simulating the dispersion of air contaminants in workrooms. However, CFD-estimated airflow and contaminant concentration patterns have not always shown good agreement with experimental results. Thus, understanding the factors affecting the accuracy of such simulations is critical for their successful application in occupation...

Abstract With the increasing demand to reduce emissions and save energy, hydraulic reservoirs require new architecture optimize their weight, space, volume. Conventional open are large, heavy, easily polluted, threaten operation of systems. A closed reservoir provides advantages small volume light compared reservoirs. In this study, a non-metallic pressure with variable is designed manufactured...
