In current study, nanoparticles and single crystals of a Zn(II) coordination complex, [Zn(dmph)I2](1), {dmph=2,9-dimethyl-1,10-phenanthroline(neocuproine)}, have been synthesized by the reaction of zinc(II) acetate, KI and neocuproine as ligand in methanol using sonochemical and heat gradient methods, respectively. The nanostructure of 1 was characte...
zro2 nanopowder was prepared by the sol-gel auto-combustion method. the product was characterized by x-ray diffraction (xrd), energy dispersive analysis of x-ray (edx) and scanning electron microscopy (sem). the average crystalline size of zro2 was obtained 62 nm. also, photocatalytic removal of nitrophenol from aqueous solution by using nanoscale zro2 under uv light irradiation was studied. th...
چکیده : آرای صادره از دادگاه ها علاوه بر شیوه های عادی از طریق فوق العاده نیز قابل اعتراض و رسیدگی مجدد هستند. در مواقعی که رای دادگاه مخل به حقوق ثالث باشد وی می تواند به ان اعتراض کند. قلمرو شمول اعتراض ثالث به تصمیمات قضایی که از آن به رای تعبیر شده محدود می گردد. ولی در مورد قرارها که به اعدادی و نهایی تفکیک می شوند، چون هیچ رویه ثابت و مشخصی در این زمینه در دادگاهها وجود نداشته و همچنین ا...
the purpose of this study was to examine the english language needs of medical students at tehran university of medical sciences . analysis of the needs took place for three groups: 320 undergraduate students, 30 postgraduate students and 20 university instructors. a triangulation approach to collect data was used in which a combination of the quantitative (using the questionnaires) and qualita...
Nano-encapsulated iron oxide in Zirconium oxide-coated mica pigments are thermally stable,innocuous to human health, non-combustible, and they do not conduct electricity. They could beapplied in several industries such as thermoplastics, cosmetics, food packaging, children toys, paints,automobiles coating, security purposes, and banknotes. Nowadays, they are highly desirable inceramic decoratio...
this research aims at answering the questions about translation problems and strategies applied by translators when translating cultural concepts. in order to address this issue, qualitative and quantitative study were conducted on two groups of subjects at imam reza international university of mashhad. these two groups were assigned as beginner and advanced translation students (10 students). ...
In this research, Ce0.8Zr0.2-xMnxO2 nano particles (x = 0.0, 0.05, 0.10) were synthesized at 600 calcination temperature by co-precipitation method. The starting materials were cerium and zirconium nitrates, manganese chloride and ammonia as a precipitating agent. The crystalline structure of the synthesized samples was studied by X-ray diffraction (XRD) technique. TEM images of the prepared Ce...
abstract target-oriented approaches to translation studies are regarded as recent theories of translation. one of the most famous theories among these approaches is descriptive translation studies presented by toury (1995). this theory gives a new dimension to translation studies and gives importance to the descriptive rather than prescriptive studies. it also identifies three sets of transla...
this study was an attempt to investigate the effect of subtitling on vocabulary learning among iranian intermediate students. to find the homogeneity of the groups, tofel test was administered to student in kish mehr institute in garmsar. after analyzing the data, 60 participants (female students) who scored within the range of one standard deviation above and below the mean, were selected as h...
In wire arc spraying, the atomizing air pressure and applied nozzle system are important factors influencing particles characteristics and coating quality. The aim of this paper is to study how the characteristics of particles such as size, velocity and temperature are influenced by the operating conditions in wire arc spray. For that, three types of wires are tested: solid wire of stainless st...
