Abstract     Logistic Regression Model (LRM) is considered as one of the most widely used statistical techniques for analyzing the relationship between variables with applications in different fields of research studies. Usually, the model seeks to predict the impact of one or several independent variables (predictor) on one dependent (categorical or response) variable through

Summary Colorectal cancer (CRC) ranks third in prevalence worldwide for both men and women. In recent years, nitric oxide (NO) and Hydrogen Sulfide (H2S) gas previously considered to be a potentially toxic chemical, has been established that have a role in cancer progression and prevention. The present investigation included two sets of the experiments, in

Restricted Detour Polynomials of Some Graphs ABSTRACT      The restricted detour distance  between two vertices  and  of a connected graph  is the length of a longest  path  in such that  The restricted detour polynomial of a graph ,denoted by  and defined as follows where the summation is taken over all unordered pairs  of vertices of . The restricted detour index  of a connected graph  is the Wiener index with respect to restricted detour

Summary           Hyperthyroidism is a thyroid disease most common among women’s, in which thyroid gland is over activated and produce too much thyroid hormone. The present study was designed to investigate the effect of hyperthyroidism on endothelin-1 (ET-1) level, hemodynamic parameters and relationship between them. Renal and liver function tests were investigated, too. Furthermore, effects of induced-hyperthyroid

Abstract This study characterizes the electronic, optical, elastic, and thermal properties of bulk and nanometric Si and ZrO2 materials through first-principles and theoretical calculations. The first part of this study presents an investigation of the physical properties, such as electronic and optical, of bulk Si and nanocrystals by using the first-principles method through pseudopotential density functional
