different researchers in different parts of the world have investigated the strategies used to translate written works ranging from novels to classroom assignments. however, by the significant increase in the number of postgraduate students in iran in the last few years, a very common kind of translation in iran includes translating abstracts of master’s theses. in this work, the researcher hav...
در این پژوهش سلول های خورشیدی آلی از نظر ساختاری و فرایند های فیزیکی که در حین تبدیل انرژی تابشی به انرژی الکتریکی در آن ها اتفاق می افتد بررسی شدند. به منظور بررسی امکان ساخت سلول با استفاده از مواد انتخاب شده، منحنی جذب و عبور و همچنین نمودار انرژی آن ها مورد بررسی قرارگرفت و نشان داده شد که این مواد شرایط لازم برای استفاده در ساخت سلول را دارند. سونش شیمیایی بستره ها، اضافه کردن لایه سد کنند...
Unstable temperature or being outside the control of a sample will cause change in quality itself. The purpose this study was to create system on waterbath with fuzzy logic using 7 labels. Used DS18B20 sensor as sensor, processor form an UNO arduino, thermostat part safety control, and displayed 16x4 LCD. Temperature selection between 30°C-60C. Design research pre-experimental methods one type ...
Schubert, Wehrberger & Frankenberg (1964) first isolated and identified 6a-hydroxytestosterone as a metabolite in human urine after intravenous administration oftestosterone to adult women. The tissue site of O6c-hydroxylation was unknown, and it could not be excluded that the metabolite had arisen by epimerization of 6fl-hydroxytestosterone. Recently we demonstrated that testosterone is hydrox...
چکیده: بررسی مقایسه ای گونه های مختلف مالاسزیا در پوست و گوش گوساله های نوزاد با مادرانشان با استفاده از روشهای مورفولوژیکی، بیوشیمیایی و فیزیولوژیکی مخمرهای لیپوفیلیک جنس مالاسزیا جزء فلور نرمال جلدی انسان و حیوانات می باشند که تحت شرایطی بیماریزا می شوند. از آنجایی که نه تنها گونه غیر وابسته به چربی بلکه سایر گونه های مالاسزیا از حیوانات مختلف جداسازی می شود لذا بررسی اپیدمیولوژی و انتشار ج...
Br-doping Li4Ti5O12 microspheres (LTOS) with micro-nano hierarchical structure are synthesized using cetyltrimethylammonium hydroxide-assisted hydrothermal and further calcination. The morphology of the obtained LTOS were characterized by X-ray diffraction, scanning electron microscopy photoelectron spectroscopy. It is found that spherical spinel-type microstructure do not change after appropri...
abstract this study evaluated and compared medical terminology and english for the students of medicine (ii) as two representatives of the textbooks available on the iranian market for teaching english to the students of medicine. this research was performed on the basis of a teacher’s and a number of students’ attitudes and the students’ needs analysis for two reasons: first, to investigate...
in this thesis, a new optically active poly(amide-imide) (pai) was synthesized by the indirect polycondensation reaction of the l-phenylalanine based diacid chloride and 4,4?-diaminodiphenylether in the presence of triethylamine in n-methyl-2-pyrrolidone. the formation of pai was confirmed by ftir, 1h nmr and elemental analysis. in next step, the surface of titanium dioxide (tio2) nanoparticles...
