Background and Objectives: There are several predictor variables for speech anxiety (SA) among students. Affective balance (AB) and social intelligence (SI) are two main factors in this field. In this study, we assess the mediating role of consequence expectation (CE) among these variables. Accordingly, this study aims to explore a model of the relationships between AB, SI, and SA mediated by C...

Abstract Background and Objective: Alzheimer’s disease (AD) is a weakening neurodegenerative disorder typified by increased b-amyloid (Ab) deposition and neuronal dysfunction causing to impaired learning and memory. Among proposed risk factors, induced oxidative stress is a main cause for incidence of the disease. The aim of this study was to determine the effects of the rosmarinic acid on lear...

To get a mole of a gas, it is necessary to calculate the intermolecular interaction. Theseintermolecular interactions can be depicted by drawing the potential energy of a pair molecule inrelation to the distance. The intermolecular potential energy surface in the mixtures of CH4-H2COgases from ab initio calculations has been explored. In ab initio calculations the basis setsuperposition error (...

Introduction: Intravenous drug users as a serious health problem in communities have economical and social effects as well as health and hygienic complications. Viral infections may be transmitted through drug injection by shared syringes among users. The aim of this study has been to determine the relative frequency of HBV, HCV and HIV infection’s markers as epidemiological data in Ahvaz. Ma...

We need some definitions from [1]. Let C ⊂ R2 be a convex body. A chord pq of C is called an affine diameter of C, if there is no longer parallel chord in C. The ratio of |ab| to 1 2 |a′b′|, where a′b′ is an affine diameter of C parallel to ab, is called the C-length of ab, or the relative length of ab, if there is no doubt about C. We denote it by λC(ab). Denote by λn the relative length of a ...
