Intensive agriculture requires the use of several phytosanitary products. Pesticides of the carbamate family are used to eliminate the crop pests by acting on their nervous system. This study aims to determine the kinetic degradation of Zectran, the

Different ratios of Portland cement and sand were mixed with radium chloride to produce radioactive cylinder specimens. Two types of sand were used (calcite and silica). The release of radon from these samples was studied. Results showed that radon r

The radioactive and physical characteristics of Syrian hot waters were studied. The concentration of uranium, its daughters and the 234U/238U-activity ratios in the hot waters were measured by gamma and alpha ray spectroscopy. The 234U/238U-activity

Portland cement was mixed with different concentrations of radium chloride (1200, 2400 and 3600 Bq) to produce radioactive sources. These sources were surrounded with cement of different thickness (1, 2 and 4cm). The release of radon from these sourc

The authors develop a technique for refining the unit commitment obtained from solving the Lagrangian. Their model is a computer program with nonlinear constraints. It can be solved to optimality using the branch-and-bound technique. Numerical result

The migration kinetics of 90Sr and 137Cs from cylindrical and rectangular cement specimens have been investigated under static and dynamic conditions with different kinds of water at room temperature. The results show that 137Cs migrates more slowly

The diffusion coefficients of 90Sr and 137Cs have been calculated from experimental data for different local rocks. The dependence of the diffusion coefficient in some rocks on the pH of the fluid under stationary or circulating conditions for the ra
