in this research, the applicability of geographic information system (gis) and remote sensing (rs) techniques was tested to assess soil erosion risk with the icona erosion model. this study was carried out in the tange bostanak area because of its variety of diverse landforms, land uses and land covers. the erosion risk assessment phase of this model consists of seven steps that mainly use slop...

Erosion caused by sand transportation in flow changing devices is a serious concern in the hydrocarbon and mineral processing industry, which entail to failure and malfunction of flow devices. In this study, computational fluid dynamics (CFD) with discrete phase models (DPM) were employed for analysis of carbon steel long radius 90-Degree elbow erosion due to the sand concentration of 2, 5 and ...

introduction: cholesteatoma is traditionally diagnosed by otoscopic examination and treated by surgery. the necessity for imaging in an uncomplicated case is controversial. this study was planned to investigate the usefulness of a preoperative high-resolution computed tomography (hrct) scan in depicting the status of middle ear structures in the presence of cholesteatoma and also to compare the...

Background and Objective: Carvedilol, a non-specific β-blocker, has been used for treatment of hypertension, stroke and congestive heart failure. The therapeutic effects of β blockers in cancer patients have been shown. Carvedilol has considerable anti-inflammatory, anti-tumor and anti-angiogenic properties. In this study, the effects of carvedilol on proliferation of human U937 and Molt-4 leuk...

To date, there are no standardized protocols available in the literature for hypersensitivity treatment molar incisor hypomineralization (MIH) patients. The aim of this study was to evaluate efficacy erosion–infiltration treatments with resin children a strong and also develop minimally invasive diagnostic–therapeutic pathway young MIH Patients clinical signs were enrolled according internation...

soil erosion and its associated land degradation represent major problems for development as well as for environmental resources protection. there is an urgent need to obtain reliable quantitative data on the extent and rates of soil erosion worldwide. the use of 137cs radionuclide for studying soil erosion and deposition is a valuable tool employed throughout the world. in the present study, u...
