The purpose of this study was to determine the effective factors (causal, intervening and contextual) on development of handball sport of IRAN using the grounded theory. This research was exploratory research and a qualitative in nature. The data gathered through documents and interview for 14 handball experts in deep-interview and semi-structured forms. The sample selected through subjective sampling and snowball approach and interviewing continued to get theoretical saturation. Then, data analyzed by grounded theory in coding process included three steps: open, axial and selective coding. The findings indicated that there were 259 effective items (open code) in the causal factors section, that were formed into 19 sub-categories and four main categories; individual factors, development resources, managerial-organizational factors and sports participation. In the contextual factors section, 53 items were classified in seven categories; handball factors, legal factors, economic factors, geographical factors, social factors, cultural factors and political factors. Also in the intervening section, 34 items were classified in two subcategories: facilitators and limiters. Generally, the effective factors obtained from this study can helpgovernment officials in making decisions and adopting appropriate strategies for the development of handball in the country.

The aim of this study was to investigate the psychometric properties of Persian version of exercise dependence scale, prevalence of exercise dependence and some related factors in male and female athletes clubs of Urmia. Subjects of this research were 325 athletes in the sample (206 males; 119 females, mean age 28.06±8 years) various team and individual sports (team sports N= 195, individual sports N=130) in the form of voluntary and available attend in this study. Hausenblas and Downs (2002) exercise dependence scale 21 with seven subscale was the instruments of the study. Exploratory and confirmatory factor analysis was used to determine validity of questionnaire, and Cronbachchr('39')s alpha coefficient was used to determine internal consistency. The results showed that the validity of exercise dependence scale 21 is desirable. Also the results showed that in this study the prevalence of exercise dependence between men and women population is not very different from each other and exercise dependence in individual sports is twice to team sports. Since exercise dependence may exist among a wide range of athletes, therefore, in order to address the adverse effects of this factor, it is necessary to examine the underlying causes and trying to modify it.

In this research, doped and undoped BaMgAl10O17 nanoparticles were synthsized using a new simple combustion synthetic method. A hybrid fuel consisting of urea and glycine was utilized in absence of reductive atmosphe .The morphology, structure, purity of sample phases and the features of nanoparticles light-glowing were investigared using field emission scanning electron microscope (FE-SEM), X-Ray Diffraction (XRD) pattern, and Photoluminescence (PL). The effect of urea fuel was studied either solely or mixed with glycine for the dopant reduction. The results of morphology and X-ray diffraction imply narrow-bar-structured rice with an approximated dimension of 45 - 65 nm with roughly high purity. In the synthesized doped europium with urea hybrid fuel and glycine, the photoluminescence emission spectrum is observed within the wavelengthrange of 400-500 nm centered at 447 nm. The scintillation responses of the samples to the 90Sr beta and 241Am gamma radiation sources and the ,discrimination capability of beta and gamma emissions in the 90Sr/90Y sources are investigated. The results showed that the activated nanoparticles having doped Eu2+ have a good sensitivity to bate particles and. can be an appropriated alternative for detection applications of beta particles in the spaces combined with gamma photons and beta particles.
