چکیده
The influence of modifier oxides (TiO2, ZnO, BaO, and PbO) on the mechanical radiation shielding properties boro-tellurate glasses is investigated. Samples with a composition B2O3-SrO-TeO2-RO (RO represents oxides) were fabricated using melt quench method, their physical, mechanical, attenuation parameters reported. For this aim, Monte Carlo simulation was employed to predict parameters, while Makishima-Mackenzie model adopted determine properties. tightly packed structure better cross-linkage density possessed by Ti-containing glass (SBT-Ti) system among titled batch. higher Poisson micro-hardness values SBT-Ti indicate its structure’s reduced free volume compactness. PbO, linear mass coefficients are highly increased compared those doped TiO2, BaO. thinner half-value layer reported at 0.015 MeV, taking 0.006, 0.005, 0.004, 0.002 for samples respectively. SBT-Pb sample (with has HVL other samples. glasses’ thickness (Deq) equivalent 1 cm lead (Pb) results demonstrated that Deq high low energy equals 11.62, 8.81, 7.61, 4.56 SBT-Ti, SBT-Zn, SBT-Ba, samples, According results, have capacity between 30 43% pure Pb gamma-ray 1.5 MeV. At (8 MeV), transmission factor reach 88.68, 87.83, 85.95, 83.11% SBT-Pb,

some properties of fuzzy hilbert spaces and norm of operators
in this thesis, at first we investigate the bounded inverse theorem on fuzzy normed linear spaces and study the set of all compact operators on these spaces. then we introduce the notions of fuzzy boundedness and investigate a new norm operators and the relationship between continuity and boundedness. and, we show that the space of all fuzzy bounded operators is complete. finally, we define...
