Application of the Grey Wolf Optimization Algorithm to Separate Middle Components in Multicomponent Mixtures [PDF]

open access: yesJournal of Nuclear Research and Applications, 2023
In this paper, optimization of a system of square cascades for separation of middle isotopes is introduced, and the optimal square cascade for use in this system is presented. In this case, 130Xe which is a middle isotope, is presented as an example. The

Stratification and Isotope Separation in CP Stars [PDF]

open access: yes, 2009
We investigate the elemental and isotopic stratification in the atmospheres of selected chemically peculiar (CP) stars of the upper main sequence. Reconfiguration of the UVES spectrograph in 2004 has made it possible to examine all three lines of the Ca ...

Photoluminescence Induced in Mineral Oil by Ionizing Radiation

open access: yesLubricants, 2023
We have studied photoluminescence (PL) properties of vacuum pump mineral oil as a function of the type and intensity of ionizing radiation exposure. The mineral oil has a simple aliphatic structure, which possesses no chromophore in the traditional sense.

Investigation the effect of M* and α0 on the separation of 4th and 8th isotopes of tellurium in a Q model cascade [PDF]

open access: yesمجله علوم و فنون هسته‌ای, 2022
One of the crucial parameters in designing the Q model cascade for the multi-component systems is the M* parameter. In this research, a code called MOTACAS has been developed to design a Q cascade, using the optimal value of the M* parameter.
