Structural and bonding patterns arising from the incorporation of fluorine atoms in a graphene-like network relevant to the deposition of carbon fluoride (CFx) films were addressed by first-principles calculations. We find that large N-member (N=8 – 12) rings, defects by sheet branching, and defects associated with bond rotation pertain to CFx. The cohesive energy gains associated with these pa...

Abstract The vortex cavitation technology shows a great development potential for antibiotic wastewater treatment. We have designed novel swirling cavitator tetracycline degradation in aqueous solution. By Computational Fluid Dynamics (CFD) simulation using ANSYS CFX flow field calculation software, it was found that the could form low-pressure area far lower than saturated vapor pressure at ex...

The problems of reprocessing and long-term storage spent nuclear fuel (SNF) at power plants with RBMK reactors have not been fully resolved so far. For this reason, are forced to search for new options the disposal fuel, which can provide least temporary SNF storage. One possible solutions problem is switch compacted in reactor pools (SFPs). As number assemblies (SFAs) SFPs increases, a greater...

Recently, a new type of low-loss variable inlet guide vane (VIGV) was proposed for improving compressor’s performance under off-design conditions. To provide more information applications, this work investigated the effect Reynolds number and clearance flow on aerodynamic characteristics VIGV. The field two representative airfoils with different chord numbers were studied widely used commercial...

This paper presents a numerical and experimental study of heating system that consists Hot Air Generator driven by biomass pellet burner to drive the NH3-H2O absorption heat pump made Robur. The aim this work is fully test for thermal potential, developing field, while driving medium capacities residential purposes, make model predicting efficiencies comparing conveyed in desorber pump. Numeric...

The software mor4ansys that allows engineers employ the modern model reduction technique to the finite element models developed in ANSYS is presented. We focus on how one extracts the required information from ANSYS and makes the model reduction implementation not dependent on a particular sparse solver in C++. We discuss the computational cost and give examples related to structural mechanics ...

one of the main architectural characteristics in the central area of iran is the relation between life and climatic conditions; e.g., the four-seasonal house which is a typical kind of the central-yard house. as the climate of isfahan is more pleasant than other desert regions in the central part of iran, wind towers are replaced with skylights to ventilate the pool area of hoze-khane. so far, ...

Background. ß-lactam antibiotics that are excreted into the intestine can damage the microflora, which can lead to serious infections such as Clostridium difficile (C. diff ). SYN-004 is a potent ß-lactamase formulated for oral use with intravenous (IV) antibiotics to degrade antibiotics in the intestine. Methods. SYN-004, formerly called P3A, was developed and evaluated by Ipsat Therapies, Hel...
