in this investigation the effect of external field on the electron density of nanostructures of cds, cdse, cdte, gaas and polymeric structure of three, four, five and six units of cds as a kind of nanosolar cells has been studied theoretically. as modeling this system in nanodimension, molecular structures has used. specific properties of molecular structures permit us to consider different sym...
در قسمت اول، طراحی و ساخت یک سنسور الکتروشیمیایی با انتخابگری بالا با استفاده ازmolecularly imprinted polymer (mip) به عنوان عنصر شناساگر برای داروی مترونیدازول معرفی شده است. mip انتخابگر نسبت به مترونیدازول وnonimprinted polymer (nip) سنتز شدند وسپس در الکترود خمیر کربن قرار گرفتند. این الکترود برای اندازه گیری مترونیدازول با استفاده از روش cathodic stripping voltammetry به کار برده شد. الکتر...
Introduction: Intranodal pathways of atrioventricular (AV) node play a vital role in the delay of conduction time in response to various atrial inputs. The present study was aimed to determine the frequency-dependent electrophysiological properties of concealed slow pathway according to a functional model of isolated rabbit atrioventricular node preparation after fast pathway ablation. Meth...
Background and Objectives: Antioxidants are used to decrease oxidation of oils and increase shelf life of foods for centuries. Nowadays, researchers investigate for the replacement of synthetic antioxidants with antioxidants from natural sources. The purpose of this study was to investigate effects of quinoa enzyme-hydrolyzed proteins on functional and antioxidant properties of the produced pep...
there is some evidence on the effects of organic acids on the functional properties of native starches. however, there is little information on such effects on modified starches. the main objective of this study was to determine the effects of l-ascorbic acid (150 mg kg-1, as the permitted level in bakery products) on functional properties of cross-linked wheat starch. once the starch was treat...
In recent years, due to the increasing popularization of data broadcasting, the volume and variety of data being broadcast are rapidly increasing. In this environment, as it is di cult for users to search for information from a large amount of broadcast data, there is an increasing demand for ltering techniques that automatically extract only the necessary data. Consequently, a number of lterin...
the seeds of lepidium sativum (garden cress) were selected as a new source of hydrocolloid and some of its fundamental physico-chemical properties such as intrinsic viscosity and functional group were determined. ftir analysis showed that this polymer was composed of carbohydrate with functional carboxyl and hydroxyl groups. intrinsic viscosity was determined to be 1.33 ml/mg in water. the hydr...
in order to evaluation the effect of different crop rotation, fertilizer and protection managements on weed seed bank properties an experiment was conducted in close house experimental glass house on the soil of 5th year of organic rotation that is conducting in university of newcastle’s nafferton experimental farm. rotation was started with grass/clover for first two years and continued with w...
