ethylene bis-stearamide is one of the important acrylonitrile-butadiene-styrene ()abs)( polymer additives, which is used as lubricant, slip agent and mold release agent. in this research, ethylene bis-stearamide for abs application was synthesized using stearic acid and ethylene diamine under reflux condition. refluxing prevented ethylenediamine from evaporation and thus the initial molar ratio...

background: there is a controversy about the relation between anti-hepatitis b (anti-hbs) antibody level and obesity. we designed this study to compare the vaccine efficacy in obese/overweight and non-obese cases. methods: in this cross-sectional study, 242 obese/overweight and 85 non-obese individuals were participated. cases were selected from a referral clinic for obesity and a referral hepa...

this study presents the synthesis of polyvinyl acetate (pvac) by solution polymerization and its partial hydrolysis to polyvinyl alcohol (pva) using alkaline alcoholysis. the influence of the molar ratio of hydrolysis catalyst (naoh) to pvac and the time and temperature of the saponification reaction on the degree of hydrolysis and molecular weight of the pva were investigated using response su...

This research has been undertaken to explore the idea of agent banking as a mean financial inclusion serve unbanked population expediently. Financial means bringing populace within formal net. paper is concerned about initiatives towards cheaper alternative. also investigates significance and competence in accessing lower income people en route for inclusion. Based on secondary sources, this re...

expansion of urban area is a well-known phenomenon in developing countries with population growth and the migration from villages to cities being two major factors. those factors reduce the influence of efforts to limit the cities boundaries. thus, spatial planners always look for the models that simulate the expansion of urban land-uses, and enable them to prevent unbalanced expansions of citi...
