Introduction: Polymer gels are modern dosimeters providing three dimensional dose distributions. These dosimeters can be used in brachytherapy in which the tumor dimension is relatively small and the dose gradient is high. In this study, the ability of the MAGICA polymer gel was investigated for assessing the absolute dose values as well as the dose distribution of low dose rate (LDR) Ir-192 wi...
در این پروژه، دوزیمتری به روش سه بعدی ژل پلیمر با اضافه شدن نانوذرات طلا به ژل پلیمر magica انجام شد. همچنین با استفاده از کد محاسباتی mcnpx ژل پلیمر به منظور مقایسه با کار آزمایشگاهی شبیه سازی شد. ژل پلیمر ساخته شده در این طرح در محدوده ی دوز cgy 600-0 خطی است و قدرت تفکیک دوز کمتر از 7/0 گری دارد. با اضافه شدن نانوذرات طلا به قطر 50 نانومتر و با غلظت های mm 1/0، mm 2/0 و mm 4/0 به ژل پلیمر ma...
George Eliot and Anthony Trollope made short visits to Prague in the mid-19th century were fascinated by such places as Jewish Quarter with its old synagogue or Charles Bridge Baroque statues. They used these motifs some of their works: The Lifted Veil Daniel Deronda Nina Balatka. Their portrayal Prague, however, is very much based on image Praga magica, legends, mysteries magic. This article a...
abstractbackground: polymer gels are an emerging new class of dosimeters which are being applied to the challenges of modern radiotherapy modalities. research on gel dosimetry involves several scientific domains, one of which is the imaging techniques with which dose data is extracted from the dosimeters. in the current work, we present our preliminary results of investigating capability of x-r...

Quella facoltà umana di fare scoperte valore grazie a eventi inaspettati cui diamo il nome serendipità è circondata da un’aura quasi leggendaria che ha contribuito alla popolarità della nozione nelle scienze sociali. È proprio quest’aura proverò dissolvere nell’articolo, riflettendo sulle insidie etnografiche si celano dietro un’incorporazione acritica scoperta serendipica nella teoria e pratic...
