abstract: â in this study, the change in the crystalline structure of gas hydrate was predicted for ternary mixture of methane-ethane-water. for this purpose, the tangent plane distance (tpd) minimization method was used. first, the calculations were performed for the binary mixtures of methane-water and ethane-water as the gas and liquid phases. the results show that for a binary mixture of th...

e nergy consumption has increased significantly in iran during the recent decades. in this study, an inter-industrial model has been improved to investigate the sources of the changes in the energy consumption of the country. the input-output tables of iran for the years 1988 and 2001 have been employed as the database of the model. the innovation of this research allows the researchers to stud...

the effects of electromagnetic fields (emfs) radiation at the frequency of 940 mhz on the structure and function of human adult and fetal hemoglobin (hba and hbf) were studied. after extraction and purification of hba and hbf, the oxygen absorption values for exposed and unexposed hba and hbf to emf were compared. the slope of oxygen absorption curve for exposed hba was increased while that for...

The aim of this study is decomposition of the changes in energy consumption with emphasizing the structural changes in Iran during 2001-2011 using Input- Output Structural Decomposition Analysis (I_O SDA). Structural changes in this study represent the changes in structure of intermediate input in sectors and also changes in structure of final demand categories. Structural changes in intermedia...

OF THESIS THE RECIPROCAL PREDICTIVE RELATIONSHIP BETWEEN PERSONALITY AND RISKY BEHAVIORS: AN 8-WAVE LONGITUDINAL STUDY IN EARLY ADOLESCENTS While the overall stability of personality across the lifespan has been welldocumented, there is also evidence of meaningful personality change. This is particularly true when individuals are going through periods of developmental transition. Over time, one...

customer segmentation is one of the main and key issues in customer relationship management studies. one of the main challenges of customer segmentation is segments’ instability and changes over time. segments’ changes can be categorized into two main categories including structural and content changes. the focus of this paper is on the structural change which is very important. to analyze the ...
