رابطه‌­ی شدت ترمولومینسانس براساس مدل سینتیک مرتبه‌­ی اول بدون در نظرگرفتن اثر فروکشی دمایی مورد استفاده قرار می‌­گیرد. این حالی است که به عنوان یک واقعیت فیزیکی باید روابط بیان‌­کننده‌­ی توجه گیرد. کار با نظر گرفتن برای اول، تابع جداسازی منحنی تابش جدیدی برحسب و دمای قله دست آمد. نحوی جدید حذف مشخصه‌­های دمایی، همان قبلی خود تبدیل می‌­شود. دزیمتر (400TLD-) :Mn2CaF بررسی گرفت. این‌­که ­شدت طبق ...

in this paper an intelligent method through general regression neural networks (grnn) is presented to estimate the depth of salt domes from gravity data. neural networks are as a good tool for automatic interpretation of geophysical data especially for depth estimation of gravity anomalies. the gravity signal is a nonlinear function of depth and density and the geometrical parameters of the bur...

Salt is a requirement material for human body but should be regulated as its excessive consumption might lead to heart disease and blood pressure. Processed foods due to high salt content might include about three quarter of the daily salt intake therefore many people consume more than their recommended allowances. Processed foods contain added salt for varieties of reasons namely to enhance th...

introduction monitoring of salt lake dry areas is an important parameter for sustainable development and environmental protection. monitoring of dried areas of the salt lake requires extraction of thematic maps at different times. powerful tool for remote sensing of the earth different ecosystems, such as playa environments, is to produce valuable and useful data. the major causes of widespread...

iodine deficiency disorders are among the most important health problems in iran. use of iodized salt is one of the oldest, most convenient and cheapest ways of idd control, although not very easy to implement. factors such as the chemical form of iodine, heat moisture, light and storage affect its stability. in this survey, salt iodine content at production site and the effect of heat, moistur...

evaluation of the geochemistry and hydrochemical quality of bam salt dome located in southern iran, was conducted in this study. two composite samples from salt units were collected and analysed by xrd and xrf to determine their mineral and elemental compositions. water samples were also collected from the only spring in the area and analysed for major anions, cations and some toxic elements. t...

potassium-argon analysis by stqwise dissolution provides a way to measure in detail the distribution of argon isotopes and potassium in rock salt. the method can be used for salt that contains only trace amounts of potassium, because the potassium and argon in detrital silicates within the salt are not released during the dissolution. water may be used as the solvent when relatively large amoun...
