الگوریتم شیبه سازی مونت کارلو اثر انباشت تپ ها در طیف سنجی گاما و محاسبه تخریب طیف ارتفاع تپ چشمه سزیم-۱۳۷ در آشکارساز یدور سدیم

الگوریتم شیبه‌سازی مونت کارلو اثر انباشت تپ‌ها در طیف سنجی گاما و محاسبه تخریب طیف ارتفاع تپ چشمه سزیم-137 در آشکارساز یدور سدیم

 In this paper, an algorithm base on Monte Carlo simulation for pileup effect in gamma spectrum of a detection system is presented whose its code was written in FORTRAN language. The code can be run in paralayzable and nonparalazable mode to obtain the pileup distortion and value of pulses pileup for any detection system. The result show, that the computed spectrum of 137Cs is in good agreement...

محاسبه ی ضرایب انباشت چشمه ی گاما با طیف انرژی پیوسته برای آب، آهن و سرب به وسیله ی کد مونت کارلو

The exposure buildup factors are important for determining the shield thickness of gamma and X-ray. Without taking this factor into account, the estimated thickness of the shield is less than what is expected which leads to an excessive received radiation exposure of staffs or patients. Given that the exposure buildup factor for the monoenergetic homogenous point sources have been calculated by...

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...

تعیین طیف زمانی نوترونها و طیف انرژی اتمهای میوندار در همجوشی کاتالیزور میونی با استفاده از روش مونت کارلو

 In this paper the cycle of muon catalyzed fusion processes has been simulated using Monte-Carlo methods. This simulation starts when muon enters the D/T mixture and follows the actual trajectories of the muonic atoms among the proceeding collisions, by using their cross sections. For this purpose a computer code has been written by Fortran language. The time dependence of the processes is take...
