The removal of impurities in molybdenum concentrate has become a new challenge for enterprises due to the cancellation pickling. Whether impurity minerals can be converted into soluble ions during roasting is important by current water washing. In this work, interaction between various elements treatment process was studied simulation experiments combined with X-ray fluorescence (XRF) and diffr...

Abstract In view of the high-precision and low-damage requirements for surface polishing hard brittle components, an abrasive jet process using a novel nozzle with specifically designed shroud was proposed. The removal mechanism investigated by simulating flow in interaction area workpiece. simulation results indicate that velocity increases greatly direction is aligned almost parallel to workp...

Search engines are an important component of our internet access, facilitating information retrieval from the web. Typically users submit a query containing combination of keywords and receive a list of web pages as result. However many web pages are being replicated on...

This study was performed to test the hypothesis that the kidneys play a primary role in the clearance of endogenous leptin from the circulation. Lean male Sprague-Dawley rats were anesthetized and subjected to various surgical manipulations of the kidneys. Sixty minutes after surgery arterial blood samples were taken at 1-h intervals for up to 8 h. Plasma leptin levels were determined by radioi...
