porous hollow glass microspheres have many uses, including encapsulation of active materials. in this paper a fast and facile method for fabricating porous hollow glass-microspheres was demonstrated by etching them using dilute hydrofluoric acid. then, a highly reactive amine was infiltrated into the etched glass microspheres. scanning electron microscopy was conducted for the hollow glass micr...
Background: Observing the enhancing plaques in magnetic resonance imaging (MRI) is one of the most valuable diagnostic modalities in confirming the diagnosis of multiple sclerosis (MS), its recurrence and for better detection of active disease. Since active lesions discovery can improve designating diffusion in time diagnosis of MS and controlling disease activity, and there is not any definite...
Background and Aim: Approaches to professional health care have changed along with changes in health measures and progression of chronic diseases. Patient participation is an international golden standard in new nursing paradigm. Despite the importance of patient participation and its routine usage in professional care, this concept is not clear, especially in social and cultural context of I...
A Nano-Encapsulated Phase-Change Material (NEPCM) suspension is made of nanoparticles containing a Phase Change in their core and dispersed fluid. These particles can contribute to thermal energy storage heat transfer by latent phase change as moving with the host Thus, such novel nanoliquids are promising for applications waste recovery systems. In present research, mixed convection NEPCM susp...
rural and nature tourism has experienced high growth over the past 20 years. one of the primary challenges facing rural tourism management is to establish a profitable and environmentally sustainable industry. moreover, sustainable tourism is a complex concept and it requires that nature and tourism activity should be studied from an integrated point of view. in this paper, we analyze how the e...
مدولاتورهای فاز متعامد کاربرد فراوانی در سیستم های مخابراتی مدرن جهت پیاده سازی ساختار های فرستنده پیدا کرده اند. امروزه تقاضا برای مدولاتورهای فاز متعامد که ویژگی هایی چون نویزفاز پایین در خروجی، توان مصرفی پایین، دقت و سرعت بالا و قابلیت مجتمع سازی زیاد دارند، افزایش چشمگیری یافته است. در پاسخ به این تقاضا، روشهای متنوعی برای تولید سیگنال های متعامد ارائه شده است که در این پژوهش دو گونه از کا...
in this thesis, we exploit a simple and suitable method for immobilization of copper(ii) complex of 4?-phenyl-terpyridine on activated multi-walled carbon nanotubes [amwcnts-o-cu(ii)-phtpy]. this nanostructure was characterized by various physico-chemical techniques. to ensure the efficiency and fidelity of copper species, the implementation of three-component strategies in click-chemistry all...
