the main objective of the present study is to investigate the feasibility of using carboxymethyl chitosan magnetic nanoparticles (ccmn) for the adsorption of cd2+. the study also reports important parameters, which affect the adsorption process, i.e., ph, adsorbent dose, contact time and concentration of cd2+, using box-behnken designs. firstly, functional carboxymethyl chitosan magnetic nanopa...

perlite or pearl stone is a natural glass which has formed by rapid cooling of viscous lava or magma. perlite is mainly composed of silica, aluminum, potassium and sodium. in this experiment, perlite was used as a low-cost source of si and al to synthesis of sodalite zeolite using the alkaline hydrothermal treatment. a statistical taguchi design of experiments was employed to evaluate the effec...

background a potential treatment for healing hepatic tissue is delivering isolated hepatic cells to the site of injury to promote hepatic cells formation. in this technology, providing an appropriate injectable system for delivery of hepatic cells is an important issue. in this regard, fibrin scaffolds were designed with many advantages over other scaffolds like cell delivery vehicles for biode...

     Drug design is generally achieved through trial and error methods, which is a time and resource consuming process and novel methods are needed to improve it. Mathematical modelling is one of the possible solutions to speed up this process. In this study, we have presented Box-Jenkins model, to predict the vasorelaxant activity (pEC50) of a set of benzopyrane compounds. We used t...

Information security using chaotic dynamics is a novel topic in the wireless sensor network (WSN) research field. After surveying analog and digital chaotic security systems, we give a state of the art of chaotic S-Box design. The substitution tables are nonlinear maps that strengthen and enhance block crypto-systems. This paper deals with the design of new dynamic chaotic S-Boxes suitable for ...
