in this study, a simple, rapid and selective method was developed for the determination of dexamethasone. the proposed method is based on inhibitory effect of dexamethasone on the oxidation of orange-g by bromate in sulfuric acid media. the reaction was followed spectrophotometrically at 478.5 nm (?max). under optimum experimental conditions, (72.6 ?mol l-1 of orange-g, 0.76 mol l-1 of h2so4, 0...
abstract cooperative learning refers to small groups of learners working together as a team to solve a problem, complete a task, or accomplish a common goal. in a cooperative environment one’s success is directly related to the success of other members because the focus on the individual shifts towards the group. to test the effectiveness of the method, using jigsaw technique, a study was cond...
theory is a base for all scientific disciplines. theorizing is an important branch in architecture too. there are a little reference that tries to define theory and show the differences between theory in architecture and theory in other disciplines. this article aimed to show the characteristics of architectural theory. at first we try to review different books and articles which are written on...

Doping Pr in 123-systems gives rise to some anomalies, such as critical Temperature suppression. Here, we show that a modification of hole localization theory based on a geometrical modeling by band percolation theory can put forward as a good explanation for the critical temperature suppression for the whole range of Pr-doping value. In this model the key concept of hole clustering is introd...
The purpose of this study was to investigate the effectiveness of reality therapy based on choice theory on psychological capital of orphan adolescent girls. The research method was semi-experimental with pretest-posttest design and control group. The statistical population of this study included all adolescent girls aged 13-19 living in Mashhad welfare center. The statistical sample included 2...
the focus of this paper is to consider the compressed sensing problem. it is stated that the compressed sensing theory, under certain conditions, helps relax the nyquist sampling theory and takes smaller samples. one of the important tasks in this theory is to carefully design measurement matrix (sampling operator). most existing methods in the literature attempt to optimize a randomly initiali...
Introduction: Marriage is described as the most important and the most basic human relationship. Increasing intimacy and marital satisfaction and reducing marital conflicts are among the most important components of a stable marriage. Counselling and therapies based on choice theory have been used as one of the effective methods on improving stable marriage components. This study was performed ...
