Background: Today, medical and health tourism is one of the most promising sectors in the tourism industry in the world, which has led the organizations involved ,and the countries interested in developing tourism ,to focus their attention on this aspect of the tourism industry and plan for it. Hence, the aim of this study was to design the marketing model of medical tourism using meta-synthesi...
B4C–Al2O3 composite powder was produced by aluminothermic reduction in Al/B2O3/C system. In this research, microwave heating technique was used to synthesize desired composite. The ball milling of powder mixtures was performed in order to study the effect of mechanical activation on the synthesis process. The synthesis mechanism in this system was investigated by examining the correspondi...

Background & aim: In some situations in quantitative or qualitative research, complementary tools would be of great help in data collection. Vignette is a data collection tool, which has been used for over 50 years in different disciplines including health sciences. Nonetheless, there is a paucity of information regarding this method. With this background in mind, the ...
The purpose of this study was to develop a Digital University model. The research method was qualitative which was used for this purpose meta synthesis. The research population consisted of 2600 scientific papers (including articles, books, dissertations and work reports), of which 84 were selected as sample. In order to validate the research findings, the critical tool of Glynn (2006) and the ...
in this research an effective and appropriate method has been developed for one-pot synthesis of new n-phenyl fulleroisoxazoline using fe3o4@sio2 nanoparticles as a green magnetically recyclable catalyst. the prepared catalytic samples were characterized by xrd, sem, ft-ir and vsm. the products have been characterized by physical and spectroscopic data such as ir, 1h nmr, 13c nmr, and ms analyses.
