The journey from championship to Sportsmanship status is a very difficult but possible way, so purpose of the research was to design a model for developing sportsmanship champion in the sportchr('39')s Iranian. The present study was Exploratory qualitative research approach of grounded theory approach of Strauss and Corbin (1998) performed. The statistical population was including experts and e...
Background: As a component of the sports industry, professional athletes are always faced with challenges, including injury, performance loss, etc. To overcome these problems, many famous athletes have turned to build their brands, as it enables them to create and maintain a market of customers and fans. Objective: The purpose of this study was to use the Grounded theory approach to design a m...
تعریف مساله،اهداف و سوالات تحقیق: در زبان محاوره ایی، شکل یک شی را با اشیایی که از قبل در ذهن دارند می شناسند. به عنوان مثال اکثر مردم نقشه ایتالیا را شبیه چکمه و نقشه ایران را شکلی شبیه به گربه می دانند. در واقع تعریف شکل به این گونه، مفهومی کیفی را دنبال می کند. اما اگر یک محقق آماری علاقه مند به ارزیابی کمی اشکال براساس ساختار هندسی آنها باشد نیازمند تعریفی مناسبتر می باشد که به نوعی مفاهیم...
The aim of the study is to develop theoretical and methodological foundations, scientific and practical recommendations for improving the management and evaluation of public debt in Ukraine. The methodological foundations of the study are a systematic approach to the analysis of the relationship of financial phenomena and processes, creative reflection on the works of Ukrainian and foreign scie...
This study discussed the role of oil revenues and banking sector credits with an emphasis on monetary policy in Iranchr('39')s economy in the form of a dynamic dynamic equilibrium model. In this study was used real seasonal per capita data for the period of 1996 to 2017 and the seasonal adjustment utilized by the Hadrik-Proskat filter and Calibration method to extract the parameters of the gene...
One of the most important developments in recent sociological theory is the relationship between ‘social structure’ and ‘social agency.’ According to George Ritzer (1996), this issue has been mostly investigated among European theorists, while, on the other side, the parallel issue of the ‘micro-macro linkage’ has attracted the main interest in American sociological theory. Again, according to ...
Lithium iron orthosilicate (Li2FeSiO4) with Pmn21 space group is theoritically investigated as a chathode material of Li-ion batteries using density functional theory (DFT) calculations. PBE-GGA (+USIC), WC-GGA, L(S)DA (+USIC) and mBJ+LDA(GGA) methods under spin-polarization ferromagnetic (FM) and anti-ferromagnetic (AFM) procedure are used to investigate the material properties, includin...
Objective(s): The partial volume effect (PVE) of single-photon emission computed tomography (SPECT) on corpus striatum imaging is caused by the underestimation of specific binding ratio (SBR). A large ROI (region of interest) set using the Southampton method is independent of PVE for SBR. The present study aimed to determine the optimal ROI size with contrast and SBR for striatum images and val...
The kinetics of reaction between 4-methylaniline (1), dimethyl acetylenedicarboxylate (2) and formaldehyde (4) has been theoretically investigated to gain further insight into the reaction mechanism. The results of theoretical calculations were achieved using the ab initio method at the HF/6-311g (d, p) level of theory in gas phase. The mechanism of this reaction had 5 steps. Theoretical kineti...
In the present work, the quantum theoretical calculations of the molecular structure of the (N-(2-benzoylphenyl) oxalamate has been investigated and are evaluated using Density Functional Theory (DFT). The geometry of the title compound was optimized by B3LYP method with 6-311+G(d) basis set. The theoretical 1H and 13C NMR chemical shift (GIAO method) values of the title compound are calculated...
