Abstract Six borate and silica glasses with varying compositions were investigated for their mechanical radiation shielding viability. Makishima-Mackenzie elastic model was utilized to study the properties of glasses. The obtained results illustrated that PbO Bi2O3 oxides reduced glass samples' properties. For instance, bulks' decreased between 68.15 44.10 GPa, shear also followed same trend fr...

Against the detrimental effects of ionizing radiation, time, distance, and shielding are three most significant protective methods. Lead is material choice for shielding, particularly personal equipment. However, lead's density, rigidity, toxicity disadvantages. In recent years, tungsten-containing rubber (TCR) other lightweight, flexible, non-toxic materials have emerged as viable alternatives...

| Associative memory cannot store items more than its memory capacity. When new items are given one after another, connection weights should be decayed so as not to exceed the memory capacity. This report presents the optimal decay rate that maximizes the number of stored items. 1. $O $8 $a $K 5-21MFNL$O5-21%b%G%k$H$7$F$N%K%e!<%i%k%M%C%H%o!<%/$NG=NO$r$O$+$kL\0B$H$J$k$P$+$j$G$J$/, %M%C%H%o!< %/$...

In this study, the monotonic effect of Ta2O5 and ZrO2 in some selected borotellurite glasses was investigated terms their impact on gamma-ray-shielding competencies. Accordingly, three niobium-reinforced (S1 : 75TeO2 + 15B2O3 10Nb2O5, S2 9Nb2O5 1Ta2O5, S3 8Nb2O5 1Ta2O5 1ZrO2) were modelled general-purpose MCNPX Monte Carlo code. They have been defined as an attenuator sample between point isotr...

Radiation shielding is crucial in many types of medical, industrial, and nuclear facilities due to the widespread usage radioactive isotopes. In this research, we examine impact tellurite 65TeO 2 –(35-x)V O 5 -xSm 3 glasses, where x ranges from 0.1 mol%, for its security radiation versus gamma attenuation capabilities. For gamma, effect that systematic replacement Sm with V has on qualities was...

Radiotherapy is one of the main options to cure and control breast cancer. The aim this study was investigate sensitivity two human cancer cell lines, MCF7 MDA-MD-231, radiation exposure at timepoints 4 h 24 after radiation. MDA-MD-231 were irradiated with different doses using a Gilardoni CHF 320 G X-ray generator (Mandello del Lario, Italy) 250 kVp, 15 mA [with half-value layer (HVL) = 1.6 mm...

Abstract For an X-ray room, there is a special window for radiation workers to monitor the patient during irradiation procedure. Lead glass commonly used as protective materials diagnostic X-rays even it known its toxicity due lead oxide in air which could be inhaled either manufacturing or recycled process. Monte Carlo simulation (EGS5 code) was study several other types of available windows s...

The radiation shielding abilities of waste marbles with different concentrations WO3 (tungsten oxide) nanoparticles were investigated. Four prepared 0, 0.05, 0.1, and 0.2 nanoparticles. study aims to investigate the effect concentration, density, particle size marble samples. linear attenuation coefficient (LAC) S1 sample, sample no WO3, was determined theoretically experimentally, results demo...

Glass samples were synthesized according to 10Li2O + 20CuO xBi2O3 (70 − x)B2O3, where x = 0, 10, 20, 30, 40 mol% by the melt-quenching method. The ability of prepared glass protect against gamma rays and neutrons was examined experimentally theoretically. mass attenuation coefficient (MAC) calculated at energies 0.662, 1.173, 1.333 MeV using 137Cs 60Co sources. obtained results compared with th...

Abstract This chapter reports on the emerging findings during first year of a design- and inquiry-based research project called Kindergarten Teacher as Researcher . The attempts to implement design for collaboration knowledge co-creation through workshop methodology Exploration Pedagogical Innovation Laboratories (EX-PED-LAB). was funded by Research Council Norway starting grant common initiati...
