A new eco-friendly process to comprehensively utilize boron-concentrate is proposed in this paper. In process, Iron-concentrate, silicon dioxide, magnesium oxide, and boric acid could be produced from boron-concentrate. The highlight of was minimal waste discharge during the whole process. Iron removal a key step ensure quality oxide. introduced goethite precipitation method remove iron very lo...

Metabolic stability is an important property of drug molecules that should-optimally-be taken into account early on in the drug design process. Along with numerous medium- or high-throughput assays being implemented in early drug discovery, a prediction tool for this property could be of high value. However, metabolic stability is inherently difficult to predict, and no commercial tools are ava...

the effect of the mollusciciding of 364 different snail habitat with bayer 73 (bayluscide), undertaken during the period january 1968 to january 1973, for the control of urinary bilharziasis bas been evaluated in khuzestan, southwest iran. the criteria for assessment were as follows:1. complete kill was obtained when no live b.truncatus was found in monthly surveys for one entire year after mol...

The aim of this study was to investigate the synthesis iron oxide pigments from IOT. sample IOT obtained through mining activity Quadrilátero Ferrífero in state Minas Gerais, Brazil. procedure carried out by hot acid leaching with hydrochloric (HCl) which allowed recovery about 95% a liquor. iron-based pigments—red (IBP_R), black (IBP_B), and yellow (IBP_Y)—were synthetised liquor selective pre...

This paper presents a new noise model and its application to Bayer color filter array (CFA). We investigate the effect of various noise models. In addition, we study three possible Bayer patterns. For example, current Bayer CFA utilizes RGGB pattern. However, one may consider other color combinations such as RRGB or RGBB patterns. To prove RGGB pattern’s superiority, we investigate each pattern...

The adsorption of dissolved hemicelluloses derived from US southern mix hardwood to cellulosic fiber is an efficient way for hemicellulose utilization. Retaining more hemicelluloses on the cellulose fibers leads to a higher pulp yield, better beatability and improved pulp strengths. The primary aim of the current work was to investigate the hemicellulose adsorption process through treating Kraf...

bioleaching of spent refinery processing catalysts using adapted indigenous strains ofacidithiobacillus ferrooxidans to recover ni and mo, and the separation of ni from bioleaching liquor usingiron magnetic nanoparticles were optimized in this study. bioleaching optimization was performed usingcentral composite design (ccd) method to optimize temperature (32 to 38oc), initial ph (1.5 to 2), par...

BACKGROUND Chinese Nong-flavor (NF) liquor is continuously and stably produced by solid-state fermentation technology for 1000 years, resulting in enrichment of special microbial community and enzymes system in its starter. Based on traditional culture-dependent methods, these functional enzymes are hardly obtained. According to our previous metatranscriptomic analysis, which identifies plenty ...

Henry’s law constant is an important equilibrium factor in the mass transfer process of volatile organic compounds (VOCs). A single equilibration technique (SET) was adopted to measure the air-water dimensionless (KH) and the dimensionless apparent (K’H) of Henry’s law constant in an air-wastewater system and air-activated sludge for VOCs at 298 K. Hydrophilic VOCs (methanol, isopropanol and ac...
