optimization of process parameter is one of the ideal goals in laser sintering. the results of this process were measured as output parameters like: density, micro hardening, macro hardening, tension, roughness, stiffness, balling. in this paper, the influence of input parameter such as laser power, scan speed, material powder and etc are surveyed on output parameter like balling affection and ...

  Abstract   The supracondylar process is a beak-like bony projection that arises from the anteromedial   surface of the humerus. The process has rarely been associated with   compression of the median nerve and seldom requires treatment. We report a case   of a supracondylar process that caused tenting of the median nerve with elbow extension   and pronation.  

Diazinon pesticide and its metabolites have been identified in aquatic systems worldwide. It was related to toxicity for aquatic organisms, animals, and humans. Waters contaminated with such persistent insecticides should be treated with suitable treatment processes. In this research, Diazinon removal from aqueous solutions by the photo–Fenton–like process (UV/H2O2/Fe...

Docolorization of Methylene Blue was investigating using a Ultrasonic/Fenton like reactor in batch mode. The effects of pH, reaction time, initial concentration of dye, H2O2 and Fe on the dye removal was studied. It was found that the increase of initial dye and H2O2 concentration and the increase of initial pH, are not beneficial for improving the dye removal efficiency. Increasing the dye con...

Background: Pharmaceuticals have arisen as emerging environmental pollutants due to their potential impact on humans, animals and microorganisms even at low concentrations. Conventional wastewater treatment plants are known to be ineffective for removal of many pharmaceuticals present in wastewater. Advanced oxidation processes are one of the most promising treatment technologies for degradatio...
