Introduction: Investigation of radiation interaction with living organs has always been a thrust area in medical and radiation physics. The investigated results are being used in medical physics for developing improved and sensitive techniques and minimizing radiation exposure. In this study, mass attenuation coefficients of different human organs and biological materials such as adipose, blood...
Abstract The aim of this study was to investigate the relationship between cognitive strategies and academic achievement among high school students in the fields of humanities, science and math – physics from Shahrekord city in the school year 89-90. The research was correlational and the statistical population included all high school students from Shahrekord city, among them 222 student...
The water relations play a fundamental role in seed comprehension of biology. In order to describe the process of drying and the effect on water activity, which controls biological change in storage, a sound knowledge of the relationship between equilibrium moisture content (EMC) and water activity/equilibrium relative humidity (ERH) is essential. The relationship between the total moisture con...
The First National Conference on Advances in Superconductivity was the first of a series of conferences in the field of superconductivity planned to be held biannually in one of the universities or scientific research centers in the country. The goal of these meetings is to bring together groups of researchers in the field of experimental and theoretical superconductivity, to discuss their la...
Abstract High school physics teachers have a difficult job to do. On the one hand, they are charged with contributing creation of scientifically literate society, while on other play pivotal role in recruitment future physicists. Given importance this dual role, might expect that training would be priority for any department. However, research suggests is often not case. While concerns been rai...
