One of the slopping processes which creates tremendous damage in many locations of Iran and the world is landslide phenomenon. Creating a landslide susceptibility map provides the possibility to recognize susceptible areas and to verify them in the environmental programs. The purpose of this research is to map the susceptibility of landslide in Taleghan watershed by establishing informational l...
Decay rates of the positronium molecule $\text{Ps}_{2}$ into two photons and an electron-positron pair are determined. Previous studies find that these very different, \[ \Gamma\left(\text{Ps}_{2}\to e^{+}e^{-}\right)/\Gamma\left(\text{Ps}_{2}\to\gamma\gamma\right)\simeq250\text{ (previous studies)}. \] This is puzzling since both processes have body final states same order in fine structure co...
One of the earliest invariants introduced in the study of finite von Neumann algebras is the property Gamma of Murray and von Neumann. The set of separable II1 factors can be split in two disjoint subsets: those that have the property Gamma and those that do not have it, called full factors by Connes. In this note we prove that it is not possible to classify separable II1 factors satisfying the...
Background: To determine the basic physical and dosimetric properties of a new synthetic single-crystal diamond detector and its application for relative small field dosimetry. Materials and Methods: The pre-irradiation dose required to stabilize detector response, dose rate dependence, photon and electron energy dependence, temperature dependence and angular dependence of MicroDiamond detector...
Background and Aims: chronic HBV infection is one of the most common viral infections in worldwide which many factors such as genetic factors are involved in pathogenesis of disease. Gamma interferon (IFN-γ) and its receptor (INFGR) play a critical role in the immune response to HBV infection. Single nucleotide polymorphisms (SNPs) are effective on level of gene expression, The aim of thi...
This paper presents the study on the effect of detector type in estimating gamma rays buildup factor. In this regard, the flux buildup factors of gamma rays emitted by an isotropic point 60Co source in mean energy 1.253 MeV was evaluated after passing through the Pb, W, Zn, and Ti sample in thickness of 1-5 cm by MCNPX. Four common detector types in simulation of measurement was defined to esti...
Let $\Gamma$ be an irreducible lattice in a product of two locally compact groups and assume that is densely embedded profinite group $K$. We give necessary conditions which imply the left translation action $\Gamma \curvearrowright K$ “virtually” cocycle superrigid: any ${w\colon \Gamma\times K\rightarrow\Delta}$ with values countable $\Delta$ cohomologous to factors through map $\Gamma\times ...
AIMS Serum gamma-glutamyl transferase activity (gamma-GT) is able to catalyse low-density lipoprotein oxidation and has been detected in coronary atherosclerotic plaques. gamma-GT has been documented as an independent risk factor for cardiac mortality in middle-aged men. The purpose of this study is to determine the prognostic value of gamma-GT in patients with coronary artery disease. METHOD...
In this work, gamma exposure buildup factors (E.B.F.) for plane sources and two-layer shields of water and lead were calculated. Also, coherent scattering effect usually left unattended in this type of geometry and application was considered. First, gamma EBFs were calculated by using MCNP, without considering coherent scattering effect for a normal and anisotropic plane source and double strat...
