چکیده

distribution of exchange interactions is due to the substitution between zinc and cadmium on tetrahedral sites. The samples in powder form were performed by the classical ceramic method. For the crystal growth, different methods were used depending on Zn and Cd concentrations. The composition was determined by X-ray measurements of the lattice constant. The direct current susceptibility measurements show that for the whole concentration range the system obey to Curie-Weiss law at high temperature. The DC magnetization, AC susceptibility and thermoremanent magnetization measurements revealed the existence of a spin-glass-like state and reentrant spin-glass behavior at low temperatures, in the middle concentration range.

Introduction of sulfonated bamboo (bamboo-SO3H) as a new catalyst for the facile synthesis of bis(indolyl)methanes

Bamboo is one of the important biopolymers which is used in chemistry. In this work, for the first time, a solid acid catalyst from bamboo was prepared from the reaction of sawdust bamboo and chlorosulfonic acid. Relevant properties of catalyst were investigated by FT-IR, XRD, SEM and TGA. The sulfonated bamboo (bamboo-SO3H) with several acid functional groups was utilized as highly ...

Investigation on the Levels of IGF-I Receptor and IGF-I Binding Protein I in the Brain of Insulin Resistant Rats

Abstract Introduction: There is limited knowledge available on the metabolism of glucose in the brain, an insulin insensitive organ. Insulin receptors hybridize with insulin like growth factor receptor (IGF-I) to transduce the signals in different areas of the brain. In this article we aimed at investigating whether the expression of IGF-I receptor and IGF-I binding proteins (IGFBP1) is change...

Analysis of the relation between coping ways with stress and Cardiac Biomarker Troponin I in coronary heart disease patients

Introduction: Coping ways with stress in coronary heart disease patients can lead to significant changes in levels of Cardiac Biomarker Troponin I, but researchers had not explored it empirically. So, the main objective of this study was to identify the relationship between coping ways with stress and Cardiac Biomarker Troponin I and also, finding coping ways that predict changes in the concent...
