naturally occurring radionuclide of terrestrial origin (also called primordial radionuclide) are present in various degrees in all media in the environment, including the human body itself. their concentrations in environment decrease continually by decaying. the main objective of this study is to evaluate the radioactivity levels and health risks due to terrestrial radionuclide in soil of yal...

the decomposition $gamma=bh$ of a group $gamma$ into a subset $b$ and a subgroup $h$ of $gamma$ induces, under general conditions, a group-like structure for $b$, known as a gyrogroup. the famous concrete realization of a gyrogroup, which motivated the emergence of gyrogroups into the mainstream, is the space of all relativistically admissible velocities along with a binary operation given by t...

gamma tocopherol content of 7 iranian sesame seeds (sesamum indicum l.) was determined by high performance liquid chromatography using c8 column and methanol, water and butanol as mobile phase. the gamma-tocopherol content varied from 563 to 1095 mg/kg in oil and 293 to 569 mg/kg in sesame seed and was in broad agreement with the codex range. a large variation was found in the concentration of ...

Background: Prompt gamma neutron activation analysis (PGNAA) is known as a non-invasive technique capable of measuring elemental concentration in voluminous samples in a short period of time. Also it is a valuable diagnostic tool for total body elemental measurements. 252Cf and 241Am-Be sources which are usually used in this method, generate not only neutrons, but also emit high-energy and unwa...

background : an elevation in the mean percentages of the gamma delta t lymphocytes per total t cells in the epithelium of the small intestine has a diagnostic value for celiac disease.  this study aimed to measure the percentages of the peripheral blood gamma delta t lymphocytes in the adults' celiac disease and healthy controls. materials and methods: in this case-control study the absolute nu...

let $r$ be a commutative ring with identity. let $g(r)$ denote the maximal graph associated to $r$, i.e., $g(r)$ is a graph with vertices as the elements of $r$, where two distinct vertices $a$ and $b$ are adjacent if and only if there is a maximal ideal of $r$ containing both. let $gamma(r)$ denote the restriction of $g(r)$ to non-unit elements of $r$. in this paper we study the various graphi...
