Importancia de la batimetría de las planicies abisales en la propagación de tsunamis transoceánicos
(Ciencia y tecnología Vol.25,No.1-2 22-33, 2007)The initial form of a tsunami originated by an homogeneous seismic source consists on a simple wave front. While the tsunami propagates in deep water, this simple form suffers several modifications ... -
Simulación rápida de la propagación del tsunami de Chile de 1960 hasta la Bahía de Hilo en Hawaii
(Tecnología en marcha Vol.20 No.4 24-29, 2007)En este trabajo se simula la propagación del tsunami de Chile de 1960, desde su región de generación hasta la bahía de Hilo en Hawái, empleando un método híbrido que permite obtener resultados en un intervalo relativamente ... -
Factores que influyen en la forma de la cola de un tsunami
(UNICIENCIA Vol. 23 65-69, 2009)The propagation speed of a tsunami depends on the depth of the ocean in which it propagates. As the tsunami crosses the abyssal plain, it suffers modifications in its form due to change in the depths of the ocean bottom. ... -

(Universidad Nacional (Costa Rica), 2010-12)Se realizó un estudio ictiológico de las capturas obtenidas con una red de trampa fija y un registro de las propiedades hidrológicas en la Laguna de Gandoca, Limón, entre abril del 2006 y julio del 2007. Se identificaron ... -
Modeling a tsunami from the Nicoya, Costa Rica, seismic gap and its potential impact in Puntarenas
(Journal of South American Earth Sciences .Vol.31 No.4 372-382, 2011)Although subduction zones around the world are known to be the source of earthquakes and/or tsunamis, not all segments of these plate boundaries generate destructive earthquakes and catastrophic tsunamis. Costa Rica, in ... -
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 ... -
Rasgos hidrográficos y batimétricos del Refugio Nacional de Vida Silvestre Ostional y áreas adyacentes, Guanacaste, Costa Rica
(Universidad Nacional (Costa Rica), 2012-12)Entre el 6 y el 11 de febrero del 2012, se realizó un levantamiento hidrográfico y batimétrico en la región situada entre Punta Guiones y Cuajiniquil, en el Pacífico norte de Costa Rica. Las temperaturas superficiales se ... -
Several Tsunami Scenarios at the North Sea and their consequences at the German Bight
(Journal of Tsunami Society International vol.32 no.1 2013, 2013)Tsunamis occurred in the past at the North Sea, but not frequently. There are historical and geological records of several tsunamis: the Storegga tsunami caused sediment deposits in Scotland 8,000 years ago and records of ... -
β- decay of 65Mn to 65Fe
(American Physical Society, 2013-10-07)The low-energy structure of 65Fe has been studied by means of γ and fast-timing spectroscopy at the ISOLDE facility, CERN. A level scheme of 65Fe populated following the β-decay of 65Mn was established for the first time. ... -
A combined experimental and theoretical study of gas sorption on nanoporous silver triazolato metal-organic frameworks
(2014-01-01)A new silver-triazolate metal-organic framework (MOF), {Ag 3[Ag5(μ3-3,5-tBu 2tz)6](BF4)2}n (2), has been prepared and structurally characterized. The CO2 sorption properties of this new MOF and previously reported isostructural ... -
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 ... -
Multiparticle emission in the decay of Ar 31
(American Physical Society, 2014-06-25)A multihit capacity setup was used to study the decay of the dripline nucleus 31Ar, produced at the ISOLDE facility at CERN. A spectroscopic analysis of the β-delayed three-proton decay of 31Ar is presented for the first ... -
The rock coast of South and Central America
(Geological Society Memoirs 2014, 2014-07)The great variety of climatic conditions, tidal ranges and wave regimes of South and Central America act on a complex geology and tectonic framework. Many of the rock and cliffed coasts of South America are strongly ... -
Sizeable beta-strength in 31Ar (β3p) decay
(Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 2014-10-07)We present for the first time precise spectroscopic information on the recently discovered decay mode β-delayed 3p-emission. The detection of the 3p events gives an increased sensitivity to the high energy part of the ... -
Evaluating SODA for Indo-Pacific Ocean decadal climate variability studies
(Journal of Geophysical Research: Oceans, 2014-10-31)Estimates of changes in upper ocean temperature, heat content, and sea level are dependent on the coverage of subsurface observations in space and time. Historically, these data are sparse, which has limited our understanding ... -
