Effect of inorganic salts and matrix crosslinking on the dose response of polymer gel dosimeters based on acrylamide
(Elsevier Ltd, 2018-07-17)
The use of additives in polymer gel dosimeters to enhance their sensitivity or to improve their performance is of
great importance for their application in radiomedicine. Inorganic salts have been used as additives with ...

Coastal currents in the Eastern Gulf of Tehuantepec from coastal altimetry
(Advances in Space Research, 2018-06-02)
we study the seasonal and interannual variability of the coastal currents along the eastern shelf of the Gulf of Tehuantepec. We use sea level from coastal altimetry distributed by the Centre de Topographie des Oceans et ...
Effectiveness of N-waves for predicting morphological changes due to tsunamis
(Elsevier, 2018)
The research on morphological changes caused by tsunamis has increased considerably in the last few
years, yet the processes behind this phenomenon are still not fully understood. This paper analyzes
and compares numerical ...
Feasibility of dose enhancement assessment: preliminary results by means of Gd-infused polymer gel dosimeter and Monte Carlo study
(Universidad Nacional (Costa Rica), 2018)
This work reports the experimental development of an integral Gd-infused dosimeter suitable for Gd dose
enhancement assessment along with Monte Carlo simulations applied to determine the dose enhancement by
radioactive ...
