Grain dust and other irritants affect the airway of allergic patients in rice-growing area during the harvest. The aim of this study was to elucidate the mechanism of airway hypersensitivity in rice-growing areas during the harvest. Firstly, the effect of rice-husk dust on eosinophil activation was studied. Secondary, the concentration of lipopolysaccharides (LPS), a potent activator of inflamm...

Rice husk is an abundant agricultural by-product reaching the output of 80 million tons annually in the world. The most common treatment method of rice husk is burning or burying, which caused serious air pollution and resource waste. In order to solve this problem, a new method is proposed to comprehensively utilize the rice husk in this paper. Firstly, the D-xylose was prepared from the semic...

Abstract Effect of additive intercropping with peanuts and long-term application organic wastes on the development arbuscular mycorrhizal red rice growth under aerobic irrigation systems raised beds has been studied through a field experiment conducted at Beleke Village, West Lombok, Indonesia, from October 2020 to February 2021. The was designed using Split Plot, three blocks two treatment fac...

Abstract—In this study, the Compressive strength of concretes made with Ground Granulated Blast furnace Slag (GGBS), Pulverised Fuel Ash (PFA), Rice Husk Ash (RHA) and Waste Glass Powder (WGP) after they were exposed 780C (exposure duration of around 60 minutes) and then allowed to cool down gradually in the furnace for about 280 minutes at water binder ratio of 0.50 was investigated. GGBS, PFA...

Assessment of pozzolanic reactivity is commonly based on a direct and indirect method which mostly used the electrical conductivity method. However,these methodsare limited by long-duration requirements or need to be done in laboratory. By modifying sandbox test measure resistivity Rice Husk Ash (RHA) as pozzolan, this investigation tries offer simpler that can situ. The RHA was heated oven wit...
