on the basis of experimental data a kinetic model for the heterogeneous interaction between alkylperoxyradicals and organic compounds in langmuir- hinshelwood approach at room temperature has been offered.the effect of oxygen on the kinetics of process in the presence, [o2]o = 1 x 1011 – 1.6 x 1012 molecules.cm-2, and absence of oxygen has been analyzed. over time the chain degenerate branching...

background: for an effective treatment planning in brachytherapy, it is necessary to know the accurate source dosimetric information such as air kerma strength, exposure rate constant, dose rate constant and redial dose distribution. the usual method to determine these factors is thermo luminescent dosimeter (tld) dosimetry. nowadays, another more accurate method is known to be the monte carlo ...

Degradation in soils is the result of a combination of chemical and, predominantly, biological events (Bollag and Liu, 1990; Wu and Nofziger, 1999). A first-order degradation model is often used to simulate the decrease of residual mass of a chemical compound in a soil system after its application (Dykaar and Kitanidis, 1996; Walker, 1974). If the first-order rate constant or half-life remains ...

We have utilized site-directed mutants to study the role of autophosphorylation of the epidermal growth factor (EGF) receptor in the regulation of receptor kinase activity and ligand-induced endocytosis. A single mutation of the major autophosphorylation site, Y1173, and a double mutation of two autophosphorylation sites, Y1173 and Y1148, did not inhibit kinase activity in vivo, using PLC gamma...
