New records of historical tsunamis obtained from Costa Rican newspapers
(American Geophysical Union, 2020-12-14)
Costa Rica has few records of historical tsunamis, due to traditionally low populated coasts and moderate tsunami potential, among other reasons. As part of the writing of the first tsunami catalog of Costa Rica, the authors ...
Tsunami Exercises on a Remote Basis: Costa Rican experiences
(Seismological Society of America, 2021-04-21)
As part of the guidelines to obtain the Tsunami Ready recognition from IOC/ UNESCO, the Pacific communities of Tamarindo and Uvita were required to perform a tsunami exercise. On the 16 March 2020 started in Costa Rica the ...
Desarrollo de materiales poliméricos para dosimetría de rayos-x con sensibilidad óptica mejorada
(Centro de Investigaciones en Laseres y Aplicaciones, 2020-10)
En este trabajo se estudia el uso de un nuevo agente, capaz de formar complejos coloreados con iones metálicos, para su
uso en dosimetría de Rayos-X (RX), con el objetivo de evaluar su efecto sobre la sensibilidad a la ...
Characteristic atmospheric states during mid‑summer droughts over Central America and Mexico
(Springer, 2020-05-10)
Annual precipitation over Central America and large areas of Mexico is typically characterised by its bimodal distribution, with a precipitation minimum in July to August that occurs between two separate maxima from May ...
Experimental characterization and Monte Carlo simulations of the dose enhancement on the millimeter scale of PAGAT infused with gadolinium
(Elsevier Ltd, 2021-05-03)
This study reports on the determination of the K-edge dose enhancement factor achieved in a polymer gel dosimeter based on acrylamide, known as PAGAT, infused with a high concentration of a clinical gadolinium-based compound. ...
Validation by Molecular Dynamics of the Major Components of Sugarcane Vinasse, On a Surface of Calcium Carbonate (Calcite)
(MDPI AG, 2021-04-18)
There is ongoing interest in the alcohol industry to significantly reduce and/or add value to the liquid residue, vinasse, produced after the distillation and rectification of ethanol from sugar cane. Vinasse contains ...
Dose-response of Fricke- and PAGAT-dosimetry gels in kilovoltage and megavoltage photon beams: Impact of LET on sensitivity
(Associazione Italiana di Fisica Medica, 2021-04-07)
Purpose: Dosimetry of ionizing radiation quantifies the energy deposited by an incident beam to the medium. This study presents the relative response of two types of gel dosimeters describing their differences by estimating ...
Reverse circulation in Bahía Santa Elena, North Pacific of Costa Rica
(Elsevier B.V., 2021-02-10)
This work describes the water circulation of Bahía Santa Elena using velocity fields and hydrographic data obtained from a ship-mounted Acoustic Doppler Current Profiler and a vertical profiler Conductivity–Temperature–Depth ...
Synthesis of a metal chelating monomer for radiation polymer dosimetry
(Elsevier Ltd, 2021-03)
To enhance the performance of polymeric dosimeters it is necessary to design novel formulations considering the mechanisms that register the absorbed dose (e.g. induced polymerization) and the readout method. The combination ...
Considerations for functional food design based on starch-protein interactions: a systematic review
(Taylor and Francis Ltd., 2021-03-26)
This systematic review aims to discuss the considerations in the design of starch-based foods from protein interactions, according to their functional, technological, and nutritional effects. Thereof, a systematic search ...
