human serum albumin (hsa) is the most abundant plasma protein in the human body. hsa plays an important role in drug transport and metabolism. this protein has a high affinity to a very wide range of materials, including metals such as cu2+ and zn2+, fatty acids, amino acids and metabolites such as bilirubin and many drug compounds. in this study, we investigated the effects of co-amoxiclav, as...
zirconium dioxide, commonly known as zirconia, is an interesting material and is receiving growing attention due to its excellent mechanical properties. the solid was characterized for surface area measurements, scanningelectron microscopy (sem), energy dispersive x-ray diffractometry (edx) and potentiometric titrations. surface titrations were carried out at the temperature range 303 to 323k i...
as a first step towards mechanization related to any product, including date fruit, it is necessary to have comprehensive information about the product. physical and mechanical properties are needed for the design of post harvest machinery and equipment. the objective of this study was to determine and compare some physical properties such as dimension, mass and volume, particulate density, pit...
Background: St. John’s wort (Hypericum perforatum L.) is an important medicinal plant that has been widely used for its antidepressant properties. Objective: In this study morphological characteristics variation of populations of H. perforatum were investigated. Methods: In this study, different morphological characteristics of 25 H. perforatum populations in Iran’s natural habitats were eva...
Background: Dose calculation algorithms play a very important role in predicting the explicit dose distribution. We evaluated the percent depth dose (PDD), lateral depth dose profile, and surface dose volume histogram in inhomogeneous media using calculation algorithms and inhomogeneity correction methods. Materials and Methods: The homogeneous and inhomogeneous virtual slab phantoms used in th...
abstract chickpea is weak in competition of weeds that damages to it at between 40 t0 60 percent. kermanshah province is one of the most important region for chickpea fields in iran. for these reosons, weed management is necessary in this crop. in order to evaluate of herbicides and stubble control on broad leave weeds control in chickpea. experiment was conducted in agricultural research stat...
In this paper,the effect of troidal magnetic field is studied in standard self-gravitating thin disks with β priscription. By applying the magnetic field, we expect to see different behaviors compared to a non-magnetic field case.The study reveals self-similar solutions for radial infall velocity, rotation velocity, surface density and mass accretion rate. Our results also show that by increasi...
