The effect of shift heavy ion irradiations on the structural and optical properties of 6 % Sb-doped SnO2 thin films deposited on quartz substrate by electron beam evaporation technique is presented. Two ion species Ni and Au with energy 120 MeV and fluence of 1 9 10 ion/cm were used. These films were characterized by X-ray diffraction, atomic force microscope, UV–visible and micro-Raman spectro...
فرض می${}$کنیم $g$ یک گروه متناهی باشد. گراف اول $g$ را با $gamma(g)$ نمایش می${}$دهیم. گروه ساده نا${}$آبلی $p$ به وسیله${}$ی گراف اولش شبه${}$تشخیص${}$پذیراست هرگاه هر گروه متناهی $g$ که $gamma(g) = gamma(p)$ است یک عامل ترکیبی یکریخت با $p$ داشته باشد. در این پایان${}$نامه نشان خواهیم داد که گروه ساده${}$ی $l_{10}(2)$ به وسیله${}$ی گراف اولش شبه${}$تشخیص${}$پذیر است. در حقی...
The article gives the performance and reliability analysis of renewable PV systems fed with a double boost converter. For analyzing system reliability, 660 W is considered converter PSO MPPT method implemented by adding secondary path to conventional converter, which shares input current reduces ripples in system. detailed system, different solar irradiations 1000 W/m2, variable irradiations, r...
Oxazolidinone-functionalized enecarbamates undergo diastereoselective E/Z photoisomerization upon direct and triplet sensitized irradiations with chiral/achiral sensitizers, showing that the enhanced product diastereoselectivity depends on the solvent and temperature.
در این پایان نامه به بررسی نامساوی های نیمه تغییراتی- تغییراتی با شرایط مرزی نیومن ناهمگن خواهیم پرداخت. فصل اول شامل تعاریف، مفاهیم و قضایای مقدماتی است و فصل دوم به بیان و بررسی قضیه نقاط بحرانی که در فصل های بعدی کاربرد زیادی دارد، اختصاص یافته است. در فصل سوم با استفاده از قضیه نقاط بحرانی، وجود دنباله ای بی کران از جواب های ضعیف، برای معادلات بیضوی شاملp - لاپلاس را بررسی خواهیم کرد. در فص...
Zinc oxide nanoparticles (ZnO NPs) and titanium dioxide nanoparticles (TiO2 NPs) are well known as photoreactive nanoparticles (NPs). Various phototoxicities of ZnO NPs and TiO2 NPs were reported on several organisms. It was still necessary to evaluate the toxicity of photoreactive ZnO NPs and TiO2 NPs due to species-specific effects under various irradiation conditions. We compared the acute t...
A model of the formation of particle tracks in emulsion has been extended through the use of biological target theory to formulate a theory of the response of biological cells and molecules of biological importance to irradiation with energetic heavy ions. For this purpose the response to gamma rays is represented by the single-hit, multitarget model with parameters m and D0, while additional p...
background: polymer gel dosimetry is still the only dosimetry method for direct measuring of threedimensional dose distributions. mri polymer gel dosimeters are tissue equivalent and can act as a phantom material. in this study the obtained isodose maps with pagat polymer gel dosimeter were compared to those calculated with egsnrs for singleshot irradiations of 8 and 18 mm collimators of gamma ...
