A model of gravity-induced distribution of material in plasma polymerized aerosols and films

A mathematical model of the volumetric part of plasma polymerization influenced by gravity is presented. Plasma-activated adhesion of monomer molecules to a surface of a germinal particle is assumed as a basic mechanism of particulate growth. The continuity equation for the flow of matter through the discharge has been formulated and solved in two extreme asymptotic approximations --for small and major duration of the process. Several non-equilibrium distribution functions of the polymer were obtained, for instance, an amount of the particles as a function of their size or time of fall. Within the adopted model this function demonstrates a sharp downward increase inside a discharge. In addition it contains such parameters as the free fall acceleration or reaction rate coefficients, variations of which enable control of the discharge and properties of the disperse medium

Effect of sodium hypochlorite on prooxidant and antioxidant homeostasis of loach embryos during early embryogenesis

The article contains data regarding the influence of sodium hypochlorite on the processes of free radical oxidation and antioxidant system of loach Misgurnus fossilis L. embryos in early stages of the development. It was showed that the effect of sodium hypochlorite added to the medium where the embryos develop, leads to disruption of prooxidation-antioxidant loach Misgurnus fossilis L. embryos homeostasis during early embryogenesis. It is proved that the sodium hypochlorite solution is empowered prooxydant manifestations in the early stages of embryogenesis wich are investigated and is inhibiting certain enzymes of antioxidant protection. It was found that the embryos at the 16 blastomeres stage of early embryogenesis are most sensitive to the action of sodium hypochlorite. Embryos at the 1024 blastomeres stage (10 division) are the most resistant to sodium hypochlorite as the content of lipid peroxidation products is reduced compared with control, whereas the activity of superoxidedismutase and glutathione peroxidase is within control value

Nа+, K+-ATPase activity of loach embryos membranes during early embryogenesis under the influence of sodium hypochlorite

The paper contains data regarding the influence of sodium hypochlorite on the activity of embryos membrane Na+, K+-ATP-ase of loach Misgurnus fossilis L. in early stages of the development. We showed that sodium hypochlorite added to the medium where the embryos develop, caused dose-dependent inhibition of the membranes Na+, K+-ATP-ase activity. We suggested that effects of sodium hypochlorite were due to oxidizing properties and its ability to disrupt membrane integrity, in particular, damaging proteins and lipids
