in this paper a new process is presented for improving efficiency of cyclone de-dusting systems. the cyclone is coupled with a specially designed cylindrical chamber which includes a rotating tube inside it with air impinging nuzzles, drilled on the peripheral surface of the tube. the nuzzles help in pushing and throwing the particles to the outer radius distances during downward flow of dust i...

Climatic chambers are highly important in research and industrial applications used to examine manufactured samples, specimens, or components controlled environment conditions. Despite the growing demand for climatic chambers, only a few published studies have specifically concentrated on performance analysis functional improvements through numerical experimental studies. In this study, 3D comp...

Moist chamber cultures are valuable for myxomycete research and can be used the analysis of ecological patterns with implications in ecosystem conservation programs. However, to make comparisons between datasets valid, method should redesigned considering potential biases affecting generation results. In present study, both effect general climate laboratory two microclimatic variables within mo...

Introduction: Due to its simplicity, fast response and high reliability, ion chamber detectors are one of the most suitable dosimetry instruments for X and gamma rays. The dosimeter    of photon beams, which used in radiotherapy centers, requires high accuracy and should pass requirements of IEC 60731 standards. About 80 percent of the IEC 60731 standard tests such as stabil...

introduction: knowledge of the anatomic location and dimension of the molar pulp chamber may preserve healthy pulp during operative procedure and reduce risk of perforation of chamber during access preparation. a review of literatures regarding the morphology of pulp chamber however revealed very little information; so the aim of this in vivo study was to measure the dimensions of first molar p...
