An assay technique, homogeneous enzyme immunoassay, is described for the quantitative determination of morphine derivatives in biological fluids. An enzyme is labeled with morphine. When the enzymelabeled morphine is bound by antimorphine antibodies, the enzyme is rendered inactive. Free morphine competes with enzyme-morphine for antibody binding sites preventing inhibition of enzyme activity. ...

Off-site construction (OSC) offers a promising means to improve the efficiency of projects. However, lack experience and knowledge regarding its use results in errors design owing conflicts omissions considerations for OSC To mitigate these problems, manufacturing assembly (DfMA) is widely used include process. Several studies concerning DfMA application have been performed, but comprehensive p...

Abstract Despite significant efforts taken to reduce hazards on the construction site, statistics across globe suggest that construction-related fatalities remain high. While prevention through design gains momentum eliminate latent health & safety at upfront stage, designers often lack experience in recognising occur later during or operational stage. To fill this gap, paper develops a con...

Many researches have focused on the optimal design of tuned mass damper (TMD) system without the effect of soil–structure interaction (SSI), so that ignoring the effect of SSI may lead to an undesirable and unrealistic design of TMD. Furthermore, many optimization criteria have been proposed for the optinal design of the TMD system. Hence, the main aim of this study is to compare different opti...

In this paper, a procedure has been introduced to the multi-objective optimal design of semi-active tuned mass dampers (SATMDs) with variable stiffness for nonlinear structures considering soil-structure interaction under multiple earthquakes. Three bi-objective optimization problems have been defined by considering the mean of maximum inter-story drift as safety criterion of structural compone...
