شبیه سازی رد تابش یونیزه کننده نوترون در اثر کامپتون با استفاده از روش مونت کارلو

بهینه سازی انرژی باریکه نوترون در نوترون درمانی با بور با روش مونت کارلو

 In last two decades the optimal neutron energy for the treatment of deep seated tumors in boron neutron capture therapy in view of neutron physics and chemical compounds of boron carrier has been under thorough study. Although neutron absorption cross section of boron is high (3836b), the treatment of deep seated tumors such as gliobelastoma multiform (GBM) requires beam of neutrons of higher ...

اثر ناهمگنی بر صحت دزیمتری در پرتودرمانی کانفورمال پروستات با استفاده از شبیه سازی مونت کارلو

Background and purpose: The human body is composed of various inhomogenous tissues with a variety of physical and radiological properties. These inhomogeneities could change isodose distributions, increase the probability of geometric errors, and eventually lead to missing of the target irradiation or incorrect isodose coverage in conformal radiation therapy (CRT) due to the uncertainties resul...

اثر بربرین در تنظیم آستروسیتهای Gfap+ ناحیه هیپوکمپ موشهای صحرایی دیابتی شده با استرپتوزوتوسین

Background: Diabetes mellitus increases the risk of central nervous system (CNS) disorders such as stroke, seizures, dementia, and cognitive impairment. Berberine, a natural isoquinolne alkaloid, is reported to exhibit beneficial effect in various neurodegenerative and neuropsychiatric disorders. Moreover astrocytes are proving critical for normal CNS function, and alterations in their activity...

شبیه سازی قله‌های ترمولومینسانس نانوذراتLiF:Mg,Cu,P با استفاده از روش مونت کارلو

The thermoluminescence (TL) glow peaks of nanoparticles was simulated by a the Monte Carlo method in which all the ordinary as well as anomalous transitions between the nanoparticle clusters are taken into account. The adjustable parameters are activation energy and frequency factor of the trap, both   radiative and nonradiative recombination, direct recombination from trap to recombi...
