The aerial measuring terrestrial gamma radiation from airborne platforms is a useful method for characterizing the radiation levels over large areas. Because of the advantage of Monte Carlo method, it is very suitable for simulation of gamma ray transport and interaction with media (soil, air, aircraft and detector), which offer alternative means of estimating detector response and calibration ...
The nuclear level density (NLD) and $\ensuremath{\gamma}$-ray strength function ($\ensuremath{\gamma}\mathrm{SF}$) of $^{63}\mathrm{Ni}$ have been investigated using the Oslo method. extracted NLD is compared with previous measurements particle evaporation those found from neutron resonance spacing. $\ensuremath{\gamma}\mathrm{SF}$ was to feature a strong low-energy enhancement that could be ex...
در این پایان نامه فضاهای دنباله ای فازی $ l_{infty} (f)$، $ c(f)$، $c_{o} (f)$ و $ l_{p} (f)$ را که به ترتیب شامل همه ی دنباله ای کران دار، همگرا، پوچ و به طور مطلق $-p$جمع پذیر می باشند، معرفی می کنیم. دوگان های $alpha$، $eta$ و $ gamma $ را برای آن ها بیان می کنیم. هم چنین تبدیلات ماتریسی فازی را روی این فضاها بررسی و شرایط لازم و کافی را برای نگاشت بودن آن ها پی...
all analytical methods are generally based on the measurement of a parameter or parameters which are somehow related to the concentration of the species.an ideal analytical method is one in which the concentration of a species can be measured to a high degree precision and accuracy and with a high sensitivity. unfortunately finding such a method is very difficult or sometimes even impossible.in...
for several years, researchers in familiarity of efl teachers with post-method and its role in second and foreign language learners’ productions have pointed out that the opportunity to plan for a task generally develops language learners’ development (ellis, 2005). it is important to mention that the critical varies in language teaching was shown is the disappearances of the concept of method ...
The Monte Carlo method was used to determine full energy efficiency of a high-purity germanium (HPGe) coaxial detector within an energy range of 53.2-2614 keV. Also, measurement was carried out for a standard Marinelli beaker of 600cm3, which was placed into the reference material of mixed gamma. The plot of the experimentally derived effic...
Non-Homogeneous Gamma Process (NHGP) is characterized by an arbitrary trend function and a gamma renewal distribution. In this paper, we estimate the confidence intervals of model parameters of NHGP via two parametric bootstrap methods: simulation-based approach and re-sampling-based approach. For each bootstrap method, we apply three methods to construct the confidence intervals. Through simul...
Gamma ray burst afterglows can be identified in single epoch observations using three or more optical filters. This method relies on color measurements to distinguish the power law spectrum of an afterglow from the curved spectra of stars. Observations in a fourth filter will further distinguish between afterglows and most galaxies up to redshifts z ≈ 1. By allowing faster identification of opt...
utilization of non-food-grade organic solvents and high shear forces in conventional liposome formation techniques has limited their applications as carriers of nutrecuticals in food industry. the objective of this research is the production of gamma-oryzanol bearing nanoliposome by using modified thermal method. nanoliposomes were produced by a suitable concentration of lecithin and gamma-oryz...
background: hydrogen peroxide (h2o2), produced by gamma ray irradiation to watery solution, was used as an analytical parameter for dosimetry of cobalt-60 (60co) radiation. materials and methods: detection of the produced h2o2 was carried out using two methods: an amperometric biosensor fabricated by immobilization of anthraquinone 2-carboxylic acid modified horseradish peroxidase on glassy car...
