Efficiency measurement and Monte Carlo simulations of a CeBr3 scintillator
(Applied Radiation and Isotopes Vol.120. 71-75 2016, 2016-11)
CeBr3 crystals meet many of the demands of high performance scintillators, due to their excellent timing properties, good effective Z and high photon yield. It is important to characterize their efficiency and to verify ...
Metodología para la Evaluación de Rutas de Evacuación en caso de Tsunami Aplicado a la Costa del Pacífico Norte y Central de Costa Rica
(Revista en Torno a la Prevención no.16 17-26 2016, 2016)
Se ha diseñado un método con el objetivo de elaborar una cartografía de rutas de evacuación en caso de tsunami a escala 1:10.000, basado en las directrices establecidas por la Comisión Europea. Las áreas de estudio son las ...
Polymer gel dosimeter based on itaconic acid
(2015-11)
A new polymeric dosimeter based on itaconic acid and N, N'-methylenebisacrylamide was studied. The preparation method, compositions of monomer and crosslinking agent and the presence of oxygen in the dosimetric system were ...
Gestionando el riesgo por tsunami desde las comunidades
(IV Congreso Nacional de Gestión del Riesgo y Adaptación al Cambio Climático, Heredia 10 y 11 de octubre 2018, 2018)
En caso de que la Comisión Nacional de Prevención de Riesgos y Atención de Emergencias (CNE) declare alerta por tsunami, las personas que se encuentran zonas de riesgo deben evacuar antes de la llegada de la primera ola. ...
Hidrography and river plumes in Golfo Dulce, South Pacific of Costa Rica
(Universidad de Costa Rica, 2015-07)
Oceanographic variables at 33 stations distributed in Golfo Dulce, Costa Rica, during the dry and rainy seasons between 2009 and 2010, were analyzed with CTD profiles, where salinity, temperature, sigma-T and currents were ...
Polycrystalline indium films in the percolation threshold regime: Time correlation between electric conduction and optical properties with film morphology
(IOP Publishing Ltd., 2014-02-21)
Polycrystalline indium films have been deposited at room temperature by electron beam evaporation on amorphous quartz substrates. Once deposited, electrical resistance and specular reflection of the films, for wavelengths ...
Variations in the geostrophic circulation pattern and thermohaline structure in the Southeast Central American Pacific
(Revista de Biologia Tropical vol.64 suppl.1 s121-s134 2016, 2016-03)
This study was conducted in the southeast region of the Central American Pacific, an area of great oceanographic importance due to the presence of various upwelling phenomena and the direct influence of the ENSO on its ...
A combined first-principles computational/experimental study on LiNi 0.66Co 0.17Mn 0.17O 2 as a potential layered cathode material
(Elsevier, 2012-08-01)
First-principles calculations are used to analyze the phase stability, formation energy, and Li intercalation potential for a series of layered cathode materials. The calculations show LiNi 0.66Co 0.17Mn 0.17O 2 as a ...
Decadal Characterization of Indo-Pacific Ocean Subsurface Temperature Modes in SODA Reanalysis
(American Meteorological Society, 2015-04-29)
Studies of decadal-to-multidecadal ocean subsurface temperature variability are fundamental to improving the understanding of low-frequency climate signals. The present study uses the Simple Ocean Data Assimilation (SODA) ...
Descifrando el clima espacial: ciclos solares y ondas magnéticas de Rossby
(Revista Uniciencia, Universidad Nacional, 2019-07)
El objetivo de esta investigación es explorar si existe una relación entre las ondas magnéticas de Rossby rápidas o lentas y ciertas observaciones de la actividad solar de largo y muy largo plazo (meses, años, décadas…). ...
