Molecular simulations and theories are important tools for studying electrolyte solutions. In this work, molecular dynamics with one of the most widely used force field combination water alkali halide monovalent ion parameters were first conducted aqueous sodium chloride solutions to predict density, self-diffusion coefficients molar conductivity. Then radial distribution functions analyzed obt...

We investigated the low-lying spectroscopy of He via the 2-neutron transfer reaction induced by the He SPIRAL beam at 15.4 A.MeV on a proton-rich target. The light charged recoil particles produced by the direct reactions were measured using the MUST2 Si-strip telescope array. Two new resonances were observed above the known 2 state in He, and the angular momentum transfer was deduced through t...

background: the method of proton induced x-ray emission (pixe) has been widely used as a sensitive technique to trace elemental analysis in both biological and medical fields. the sensitivity of this powerful method is in the order of ppm .the aim of this work is to analyze structural composition of 4 heavy trace elements with z greater than 24 (mn, fe, cu, zn) in two kinds of gallstones and to...

the first step in walnut breeding programs is to identify and evaluate superior genotypes of fruit trees. hence, there are various walnut breeding programs in various areas of iran. a study aimed to evaluate the morphological and chemical characteristics of selected superior genotypes of walnut was conducted in the shahroud region in 2011-2012.  the following genotypes were selected in this stu...

The 21-cm line emission from a 7 × 6 deg2 region east of and adjoining the Small Magellanic Cloud (SMC) has been observed with the Australia Telescope Compact Array and the Parkes telescopes. This region represents the westernmost part of the Magellanic Bridge, a gas-rich tail extending ∼14° to the Large Magellanic Cloud. A rich and complex neutral hydrogen (H i) structure containing shells, bu...
