Ionizing radiation is electromagnetic radiation that has sufficient energy to remove electrons from atoms. Ionization results in the production of negatively charged free electrons and positively charged ionized atoms. Ionizing radiation can be classified into two categories: photons (X-radiation and gamma radiation) and particles (alpha and beta particles and neutrons). Five types or sources o...

Alpha particle irradiation from radon progeny is one of the major natural source of effective dose for public population. Oncogenic transformation is a biological effectivness of radon progeny alpha particle hits. Various biological models including cultured cells and animals have been found useful for studing the carcinogenesis effects of radon progeny alpha particles. In this paper, sugarscap...

Our objective was to evaluate the associations of individual apolipoprotein A-I (apoA-I)-containing HDL subpopulation levels with ABCA1- and scavenger receptor class B type I (SR-BI)-mediated cellular cholesterol efflux. HDL subpopulations were measured by nondenaturing two-dimensional gel electrophoresis from 105 male subjects selected with various levels of apoA-I in pre-beta-1, alpha-1, and ...

Introduction: In this study, we investigated contaminants in sediments of reverse osmosis water systems in Iraqi households. These filters are imported from the US and Taiwan and are available in the Iraqi market. The rate of environmental pollutions in residues of the water filters was examined by measuring alpha particles emission rates and the concentration of heavy metals. Material and Met...

Abstract In modern, highly optimized stellarator configurations where prompt fusion alpha particle losses from the plasma core are absent, particles can still be lost due to stochastic orbits which result in delayed losses. One mechanism leading changes trapping class during drift motion along contours of parallel adiabatic invariant J ∥ jumps when crossing boundaries. Another mechanism, is mai...

We elucidate the fate of neighboring two and three-$\alpha$ particles in cold neutron matter by focusing on an analogy between such $\alpha$ systems Fermi polarons realized ultracold atoms. describe in-medium excitation properties particle neutron-mediated two- interactions using theoretical approaches developed for studies atomic systems. numerically solve few-body Schr\"odinger equation withi...

For this paper, we studied the time evolution of a system coagulating particles under generalized electrorheological (ER) kernel with real power, $K\left(i,j\right) = \left( \frac{1}{i}+\frac{1}{j} \right)^\alpha$, and monodisperse initial conditions. We used combinatorial framework in which cluster sizes were discrete binary aggregation governed system. modified previously-known solution for c...

We introduce and analyze a novel type of coalescent processes called cross-multiplicative that models system with two types particles, $A$ $B$. The bonds are formed only between the pairs particles opposite same rate for each bond, producing connected components made both types. solve Smoluchowski coagulation equations obtained as hydrodynamic limit corresponding Marcus-Lushnikov process. estab...
