Interpretation of In-air Output Ratio of Wedged Fields in Different Measurement Conditions
Introduction: The head scatter factor (Sc) is one of the important parameters for monitor unit (MU) calculation. There are multiple factors that impact the Sc values, such as, head structures, back scattering in to dose monitoring chambers, wedges and so on. This study aimed to investigate the variations of SC with different build-up cap materials, wall thickness, Source to ...
متن کاملبررسی بهبود دهنده‌های مختلف بر روی خصوصیات سنگ‌های ضعیف
In accordance with development of coastal area around the worlds, constructing breakwaters with sophisticated materials is increased. In the south costs of Iran, rock mass breakwaters is more common than other types of breakwaters. However enough source of good rock deposits is quite rare. In that region, Lomashel rock is the dominant rock formation. Therefore using different coating materials ...
متن کاملMeasurements of output factors using different ionization chambers and build up caps
Background: The aim of this work was to study the output factors for Linac using different ionization chambers and build up caps. Materials and Methods: Output factors were measured for open square fields (3 × 3 cm to 40 × 40 cm) defined by collimator jaws for 6 and 15 MV photon beams from a Varian Clinac 2100C accelerator were measured. The measurements in air were performed using Com...
متن کاملComparison of Compressive Properties Between Va-cuum Infusion and Hand Lay-Up Method Toward Bal-sa Core Sandwich Composites
The aim of this work is to evaluate the influence of fabrication methods on the com-pressive properties of sandwich composites using both experimental work and numerical simulations. Two types of sandwich composites with E-glass/Kevlar/polyester resin facings and End-grain balsa wood as core have been produced by vacuum infusion processing (VIP) and hand-lay up (HL) method. Compression tests on...
متن کاملCharacterization and Evaluation of Novel Film Forming Polymer for Drug Delivery
In this study, Damar Batu (DB) − a novel biomaterial− is evaluated for its potential application in pharmaceutical coating. DB is a whitish to yellowish resin, characterized initially in terms of solubility, acid value, molecular weight (Mw), polydispersity index (Mw/Mn) and glass transition temperature (Tg). Neat plasticized films of DB are investigated for mechanical, water vapor transmission...
