In this study, the rate equation analysis of a BH-laser diode was performed for output carrier density (No) using the zero-degree solution of the Volterra series. The carrier rate equation of the laser diode was analyzed in terms of input carrier density (Ni) and output carrier density modeling (Ni − No) , with respect to the DC current (Io) . The polynomial root, which is obtained from the zer...
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
liquid membrane processes have attracted many interests in recent years for removal of heavy metals such as cadmium from industrial wastewaters. in this study, a modified hybrid liquid membrane system is introduced. the setup is worked by applying the water-insoluble dioctyl phthalate as the organic solvent. n-octanol and tetra butyl ammonium bromide are added to the organic phase to increase t...
Introduction: [18F]-6-thia-14-fluoro-heptadecanoic acid 3b, a free fatty acid, has been used in myocardial PET imaging. In order to establish an automated synthesis module for routine production in the country, a study performed for optimization of the production conditions as well as making modifications. Methods: [18F] Benzyl-14-Fluoro-6-thia-heptadecanoate 2b was prepared in no-carrier...
Thyroxine, the principal thyroid hormone, circulates in blood almost completely bound to carrier proteins. The main carrier is thyroxine-binding globulin (TBG). However, only the free (unbound) portion of thyroxine is responsible for the biological action. Further, the concentrations of the carrier proteins are altered in many clinical conditions, such as pregnancy. In normal thyroid function a...
Background and Aims: Nowadays reconstruction of alveolar defects has become one of dentists' problems especially in areas which are going to get dental implants. Inorganic bovine bone mineral (Bio-Oss) is one of the most popular graft materials that acts as a structure for migration of osteoblasts. If migration, proliferation, and differentiation of osteoblasts can be promoted by a material, it...
In MDCK cells, choline uptake, the first step in the CDP-choline pathway for the biosynthesis of choline-containing phospholipids and osmolytes, occurs via both a transport system highly specific for choline and a non-specific pathway. The specific choline carrier is present at the apical domain of cells grown on dishes and is sodium-independent. Growing the cells on a permeant support results ...
The main purpose of this research is to investigate the effect of mandatory rotation of auditors on the relationship between audit fees and market value added, economic value added and growth opportunities for listed companies in Tehran Stock Exchange. Research hypotheses based on a statistical sample of 106 companies during an 11-year period from 2007 to 2017 were tested using the multivariabl...
Microporous glass ceramic with skeleton of CaTi4(PO¬4)6 with average pore size of 12.7 nm has been synthesized and used as a carrier of glucose oxidase. The glass ceramic was prepared by controlled heat treatment of glass samples, which causes the phase separation in their structure and creates CaTi4(PO¬4)6 and β-Ca3(PO4)2 phases. The β-Ca3(PO4)2 phase was dissolved by soaking the glass ceramic...
