background and objectives: discharge of wastewater from textile dyeing industries has been a problem in terms of pollution and treatment of these waters is a great task. keeping this in mind, the aim of our current research is to study the effect of various bioprocess variables on decolorization of an azo dye, congo red, by a fungal isolate, aspergillus niger hm11. materials and methods: centra...

Objective: The objective of the present study was to develop and optimize Astragalin-loaded polymeric nanoparticles (AST-NPs) using a central composite factorial design (CCD). Methods: AST-NPs were prepared by dialysis method. CCD employed influence formulation factors, polymer concentration, aqueous organic phase ratio, process parameter stirring time on dependent physicochemical characteristi...

Co-fermentation of cheese whey (CW) and thermal-alkaline pre-treated Yerba Mate (Ilex paraguariensis) waste (YMW) was performed aiming to produce biohydrogen and/or short- medium-chain organic acids. Central Composite Designs (CCD) chosen as the experimental design for evaluating combinations three independent variables namely YMW concentration, pH inoculum concentration in hydrogen yield (H2Y;...

Previous studies have shown that air pollutants a significant impact on cardiovascular and cerebrovascular diseases (CCD), but these focused more provincial capitals or large cities. This study was the first time to explore effects of CCD in Luoyang. In this study, generalized additive model (GAM) used establish single-pollutant model, multi-pollutant stratified modes age, sex season evaluate P...

Physical properties are one of the ‎drawbacks oil palm wood ‎‎(OPW) and they need to ‎be ‎improved via an appropriate method. The ‎response surface methodology (RSM) based on central composite ‎design (CCD) was used evaluate optimize parameters a hydrothermal treatment ‎and create ‎empirical model mass loss (ML, %), equilibrium moisture ‎content ‎‎(EMC, anti-swelling efficiency (ASE24h, %)‎‏ ‏r...

Charged-coupled device (CCD) detectors have been widely accepted as detectors for collecting X-ray diffraction images. The CCD detector offers a sensitive detection system well suited for diffraction analysis and, compared with other detectors on the market, a relatively rapid system for read-out of the collected image. The two predominant markets for the CCD detector have been those in which r...

The results of on-orbit measurements of the STIS/CCD imaging throughputs are reported. Wavelength-dependent aperture corrections and revisions to detector and filter throughput curves are presented. The throughput of the F28X50LP filter is found to be close to prelaunch estimates. Initial on-orbit measurements of this filter had suggested a 28% lower throughput, but we find instead that the ove...

BACKGROUND Allergy diagnosis by determination of allergen-specific IgE is complicated by clinically irrelevant IgE, of which the most prominent example is IgE against cross-reactive carbohydrate determinants (CCDs) that occur on allergens from plants and insects. Therefore, CCDs cause numerous false-positive results. Inhibition of CCDs has been proposed as a remedy, but has not yet found its wa...
