Monte Carlo simulations of backscattered electron coefficients and average penetration depths for Cu, Au, and Al under electron irradiation by Sami Mohammed Alsharari

“…Therefore, a Monte Carlo (MC) simulation was conducted to examine and explore the electron backscattering coefficients and average penetration depths of copper (Cu), gold (Au), and aluminum (Al) when bombarded by energetic electrons with energies ranging from 0 to 60 kilo-electron volts (keV) at normal incidence. The results showed strong agreement with experimental data. …”

Production of Californium-252 by Using Reverse Reaction Technology by Aqeel L. Oudah, Sameera A. Ebrahiem, Khalid H. Mahdi

“…      In the current work, Calculate cross sections for  252Cf (α,3n)253Fm  reaction Use of interpolation and cross-section sampling published in the international literature to select the appropriate interaction of ground-level energies in a computer-based program (MATALAB-17.0) , in steps of energies (0.2 Million electron volts). Given the importance of the 252Cf isotope and its entry into the industrial and medical fields, there was a need to determine the energy of the incident neutron to produce this isotope, relying on the masses of the entering and leaving particles and the values ​​of angular momentum to obtain an equation and according to the theory of the opposite reaction. …”

Ilmenite Inclusion: A Solution towards Solid Sagging for Hematite-Based Invert Emulsion Mud by Salem Basfar, Ashraf Ahmed, Salaheldin Elkatatny

“…A slight drop (4%) in mud weight was noticed upon adding the ilmenite, whereas the emulsion stability was enhanced from 551 to 574 volts with the 50% ilmenite content. The rheology and viscoelasticity measurements showed that 50/50% combination improved the yield point (YP) by 50% with a trivial 1 cP increment on plastic viscosity (PV), hence enhancing the YP/PV ratio by 46%. …”

« Quelque chose d’inaudible à propos d’un prophète et d’un hamster » : le terrorisme à la Mathias Énard by Kathryne Fontaine
