background: an effective polymer gel dosimeter can be fabricated by varying the composition of its chemical components. materials and methods: the magat gel dosimeter formulations that used different compositions of methacrylic acid (maa) and gelatin were extensively investigated in the present study according to the r2–dose response and r2–dose sensitivity. the irradiation of magat gel was per...

The Scott-Magat polymer theory, which assumes that polymers have heterogeneous structure and takes into account the polydispersity in the molecular weight of polymers, is a method to model asphaltene precipitation conditions. The traditional Scott-Magat polymer theory based models assume that the precipitated phase consists of asphaltene only. In the present work, we introduce a model based on ...

In managing a multipurpose dam, knowledge of inflow is essential in planning and scheduling discharges for optimal power production and irrigation supply, and flood control. Utilization of satellite imagery improves inflow estimates provided by digital spatial data instead of those from calculations on drawn maps; the former yields measurements over an area instead of extrapolations from point ...

Abstract The spatial distributions of neutrons and gamma rays in the epithermal mode Kyoto University Reactor were measured using a MAGAT-type polymer gel detector doped with LiCl at 6 Li concentrations 0, 10, 100 ppm. Reasonable for thermal obtained 0 100ppm.

Proton pencil beam scanning is a dynamic delivery technique with excellent conformability to the tumor volume. The accuracy of spot size and positions will have significant effect on delivered dose distribution. We employed polymer gel dosimeters measure for Shanghai Advanced Therapy facility (SAPT). Polymer (MAGAT-f PAGAT) were utilized full width at half maximum (FWHM) various depths basis th...

A major overwater experiment, MAGAT-80, has been undertaken to verify the use of aerosol spectrometers to calculate optical extinction in the marine boundary layer. Techniques for data averaging and for extrapolation to large particle sizes are described. Coincident optical, aerosol, and meteorological measurements by ship, aircraft, and an overwater optical range show that aerosol spectra can ...
