This study focused on the effect of electro slag remelting process (ESR) on microstructure and composition of an as-cast alloy of Cu-Cr-Zr. These observations revealed that applying ESR process results in a more uniform distribution of alloying elements, however a slight aggregation of large precipitates and inclusions existed in as-cast ingot was found. Additionally, impurities like P, S and M...

the optimum fermentation times of black tea manufactured by two systems of orthodox and ctc (cut, tear & curl) were investigated by measuring the quality parameters of black tea, like: theaflavin, thearubigin, highly  polymerized substances and total liquid colour during the fermentation stage. optimum fermentation times from the beginning of fermentation were determined to be 60 min and 15...

epilepsy is the third most common chronic brain disorder which is characterized by an enduring predisposition to generate seizures. mesial temporal lobe epilepsy (mtle) is the most common type of refractory epilepsy. increasing evidence indicates that neuroinflammation plays a critical role in the pathogenesis of mtle. hundreds of micro-rnas have been found to be abnormally expressed in epilept...

cadmium oxide rhombus-shaped nanostructure was synthesized using hydrothermal process followed by heating treatment. clearly, x-ray diffraction pattern demonstrated the formation of cdo crystalline phase. scanning electron microscopy (sem) showed that the obtained rhombus-like structure is composed of nanoparticles with the average size of 29 nm. in addition, we evaluated adsorption of organic ...
