a novel acrylic acid-functionalized fe3o4 magnetic nanoparticle with a core-shell structure was developed for utilization as a heterogeneous organosuperacid in chemical transformations. the structural, surface, and magnetic characteristics of the nanosized catalyst were investigated by various techniques such as transmission electron microscopy (tem), thermogravimetric analysis (tga), and ft-ir...
context resilience can be seen as an adaption to stress, such as that caused by health problems or disease, that attenuates the negative effects of stress. the present research performed a systematic review and meta-analysis to study resilience scores among adults diagnosed with chronic physical diseases. evidence acquisition electronic databases, including persian language (scientific informat...
background praziquantel, an antischistosomal compound, is used as first-line drug for chemotherapy of schistosoma japonicum since 1984. in this article, we conducted a systematic review and mete-analysis to evaluate the efficacy and safety of different dosages of praziquantel (pzq) for treatment of schistosoma japonicum. evidence acquisition: a number of six articles published in peer-reviewed ...
thermal barrier coatings (tbcs) are used to provide thermal insulation to the hot section components of gas turbines in order to enhance the operating temperature and turbine efficiency. hot corrosion and thermal shocks are the main destructive factors in tbcs which comes as a result of oxygen and molten salt diffusion into the coating. in this thesis atmospheric plasma spraying was used to dep...
