Assume that $A$ is a Banach algebra. We define the $beta-$topology and the $gamma-$topology on the space $QM_{el}(A^{*})$ of all bounded extended left quasi-multipliers of $A^{*}.$ We establish further properties of $(QM_{el}(A^{*}),gamma)$ when $A$ is a $C^{*}-$algebra. In particular, we characterize the $gamma-$dual of $QM_{el}(A^{*})$ and prove that $(QM_{el}(A^{*}),gamma)^{*},$...
Yrast states in mirror nuclei 55Co and 55Ni have been populated with a radioactive ion beam using the Isotope Separator On-Line method. A shielded array of 7 Compton suppressed germanium detectors recorded reaction gamma-rays. For channel selection, an array of 128 independent silicon detectors was used to differentiate exit channels with different number of proton and alpha particles emitted...
several common approaches are used for disinfection of water in this section, but using the approaches (e.g. chlorination) are accompanied with hazardous by-products and also lead to notable changes in odor and flavor of water. gamma irradiation as an emerging method has been encouraged currently by fao/who for water, wastewater and food treatment. coliform bacteria belong to common contaminant...
background: previous investigations have revealed, cimetidine, a histamine h2-receptor antagonist, show radioprotective effects against gamma- and neutron-induced micronuclei in bone marrow erythrocytes. in this study, the anticlastogenic effects of famotidine and ranitidine, which act similar to cimetidine as histamine h2-receptor antagonists, was investigated. materials and methods : balb/c m...
in this study, preparation of nano-sized gamma alumina with high specific surface area and high yield by thereaction between aluminum nitrate and sodium carbonate, without using any surfactant is reported. bohemite (aluminum oxyhydroxide) was prepared as a precursor by strict control of ph and reaction temperature. the gel produced was purified by washing followed by centrifugation. the specifi...
