Purpose: Cement is a major construction material used in civil engineering works due to which its demand very high. The consumers and suppliers of the cement market may feel that every brand they are buying selling good quality. study has been focused assess consumption different brands available Pokhara Metropolitan city. Design/Methodology/Approach: suppliers’ data field were collected. withi...

We describe a bottom-up surface functionalization to design hybrid molecular coatings that tether biomembranes using wet chemistry. First, monolayer was formed by immersion in NH2-Ar-SO3H solution, allowing aryldiazonium salt radicals spontaneously bind it via strong C bonding. After formation of the air-stable and dense (–Ar-SO3H), subsequent activation used form highly reactive –Ar-SO2Cl grou...

PURPOSE The ocular toxicity of various compounds is typically determined by the Draize eye test, which has been criticized in the past for its lack of reproducibility and the cruelty associated with harsh testing conditions for animals. In this study, a liposome-based assay was developed for estimating ocular toxicity of surfactants. METHODS The release of calcein dye from liposomes induced b...

The aim of this study was to design a convenient, specific, sensitive, and continuous lipase activity assay using natural long-chain triacylglycerols (TAGs). Oil was extracted from Parinari glaberrimum seed kernels and the purified TAGs were used as a substrate for detecting low levels of lipase activities. The purified TAGs are naturally fluorescent because more than half of the fatty acids fr...

Surfactant-templated silica thin films are potentially important materials for applications such as chemical sensing. However, a serious limitation for their use in aqueous environments is their poor hydrolytic stability. One convenient method of increasing the resistance of mesoporous silica to water degradation is addition of alumina, either doped into the pore walls during material synthesis...

BACKGROUND Mucosal surface hydrophobicity is a key factor of the gastric acid defence barrier. In the colon, surface hydrophobicity is high but its biological function remains unexplored. AIMS To investigate the functional changes of the barrier due to removal of the surface active phospholipid layer by a detergent, or to reinforcement of the surface active phospholipid by local application o...
