Concrete’s binder can be substituted with rice husk ash, metakaolin, kaolin clay, GGBS, and other agricultural industrial byproducts waste materials, which lowers greenhouse gas emissions, namely carbon dioxide (CO2). When employed in the manufacturing of concrete, aforementioned items reduce amount water required have no discernible impact on material’s long-term performance. Combination metak...

Double layer (DL) ZnO/ZnO:Ag has been synthesized with variations in molarity of 0.1, 0.3, 0.5, and 0.7 M its application as a degrading agent for methanil yellow dye. This study aims to determine the effect DL on crystallinity photocatalytic activity degradation. was using sol-gel technique deposited spray coating technique. The results were characterized by XRD particle size. carried out imme...

Abstract Introduction Current teaching of calculations to pre-registration pharmacy technicians covers a variety areas, including dose calculations, conversions, molarity, percentages, displacement values and dilutions. Within the University East Anglia course these are taught over 2 years with 5 exams spread throughout course. The extent how much each calculation is used in practice unknown. C...

Two new papain inhibitors have been synthesized where the terminal α-carboxyl groups of Z-Phe-Ala-COOH and Ac-Phe-Gly-COOH have been replaced by a proton to give Z-Phe-Ala-H and Ac-Phe-Gly-H. We show that for papain, replacing the terminal carboxylate group of a peptide inhibitor with a hydrogen atom decreases binding 3-4 fold while replacing an aldehyde or glyoxal group with a hydrogen atom de...

As part of an ongoing effort to improve the technique of immunoscintigraphy for the detection of human carcinomas with radiolabeled monoclonal antibodies (MABs) to carcinoembryonic antigen (CEA), we have developed a series of MABs to CEA and have studied the effects of low- and physiological molarity buffers on their CEA binding and affinity, as well as their cross-reactivity with granulocyte g...

In this article, we proposed a facile one-step synthesis of Fe3O4 nanoparticles of different shapes and sizes by co-precipitation of FeCl2 with piperidine. A careful investigation of TEM micrographs shows that the shape and size of nanoparticles can be tuned by varying the molarity of piperidine. XRD patterns match the standard phase of the spinal structure of Fe3O4 which confirms the formation...

The presence of cupric ions or ferric ions was found to enhance the development of color in the indole reaction for the calorimetric determination of deoxyribonucleic acid. The addition of calcium, cobaltous, magnesium, manganous, nickel, or zinc ions did not produce this effect. In the absence of added cupric ions, the indole reaction gave variable results, and the color developed to less than...
