Concern for the sustainable management and recycling of solid waste is becoming more visible in all sectors economy. This study explores possibility using coal ash residue (waste from Kazan CHPP-2) as a substitute fine-grained aggregate sulfur concrete. The trend towards an increase level utilization heat power engineering important task. chemical composition, microstructure mechanical properti...

Interferon (IFN) provides effective treatment in some patients with chronic hepatitis. The clarification of factors predictive of therapy response would be helpful in identifying patients who would benefit from treatment. In this study, we evaluated the potential utility of Tc-99m sulfur colloid liver/spleen and Tc-99m-disofenin hepatobiliary scintigraphy to predict therapy response to IFN in p...

In this paper the influence of two different sizes of silica particles (micro-silica and nano-silica) was studied on mechanical properties of sulfur and sulfur composite. To improve the structural properties, sulfur was plasticized using dicyclopentadiene (DCPD) and methyl styrene (MSt). Plasticized sulfur composite was prepared by melt blending of plasticized sulfur and silica particles. T...

introduction: sulfur is the key element for higher crops and plays an important role in the formation of proteins, vitamins, and enzymes. it is a constituent of amino acids such as cysteine and methionine, which act for the synthesis of other compounds containing reduced sulfur, such as chlorophyll and utilization of phosphorus and otheressential nutrients.deficiency of this nutrient in soil is...
