AbstractWe report the detail characterizations and <italic>γ</italic>-radiation protecting characteristics of some new types of cadmium (Cd)-bismuth (Bi)-lead (Pb)-zinc (Zn)-borate glasses of the form (70-x)B2O3-10ZnO-10PbO-10CdO-xBi2O3 (with x = 0 to 20 mol%) synthesized via melt-quenching process. The influence of various Bi2O3 contents on the <italic>γ</italic>-radiation shielding traits of the obtained glass samples was evaluated by exposing them at different <italic>γ</italic>-ray energies (0.356, 0.662, 1.173, and 1.33 MeV) which were recorded by the NaI detector. XRD analyses of the as-quenched specimens showed their glassy phase. A comparison between theoretically computed (Phy-X and XCOM software) and experimentally measured various shielding parameters of the glass samples were performed. Irrespective of the Bi2O3 contents, the values of the mass attenuation coefficient, effective atomic number and effective electron density of the prepared glass samples were reduced with the increase of <italic>γ</italic>-ray energies. Furthermore, the theoretically calculated values of all the shielding parameters were agreed well with the measured ones. Regardless of the <italic>γ</italic>-ray energy exposures, the shielding capacity of the studied glasses was improved with the increase of Bi2O3 doping contents. The proposed glass compositions were asserted to be useful for the <italic>γ</italic>-ray absorber applications.

The main idea of this research is to consider fibrewise pairwise versions of the more important separation axioms of ordinary bitopology named fibrewise pairwise - spaces, fibrewise pairwise - spaces, fibrewise pairwise - spaces, fibrewise pairwise -Hausdorff spaces, fibrewise pairwise functionally -Hausdorff spaces, fibrewise pairwise -regular spaces, fibrewise pairwise completely -regular spaces, fibrewise pairwise -normal spaces and fibrewise pairwise functionally -normal spaces. In addition we offer some results concerning it.

Obliquely deposited (70o) Bi, Sb, and Bi-Sb alloy thin films have been prepared by thermal
resistive technique. Structural properties of these films were studied using XRD. Their resistance and
voltage responsivity for Nd:YAG and CO2 laser pulses have been recorded as function of operating
temperature between 10 oC and 120 oC. It was found that the maximum responsivity for these detectors
can be obtained at 75 oC. On the other hand, the dependence of responsivity on the width of detectors was
investigated.

AbstractIn the present study, Čech fuzzy soft bi-closure spaces (Čfs bi-csp’s) are defined. The basic properties of Čfs bi-csp’s are studied such as we show from each Čfs bi-csp’s (<italic>u, L1, L2, S</italic>) we can obtain two types of associative fuzzy soft topological spaces, the first is a fuzzy soft bitopological space (<italic>U, τL1 , τL2 , S</italic>) and the second is a fuzzy soft topological space (<italic>U, τL1 </italic> ...
