    • The 2017 México Tsunami Record, Numerical Modeling and Threat Assessment in Costa Rica 

      Chacón-Barrantes, Silvia (Springer, 2018-03-30)
      An Mw 8.2 earthquake and tsunami occurred off- shore the Pacific coast of Me´xico on 2017-09-08, at 04:49 UTC. Costa Rican tide gauges have registered a total of 21 local, regional and far-field tsunamis. The Quepos gauge ...
    • The magnetic dispersion 

      Páez, Jorge; Semionova, Liudmila (Editorial de la Universidad Nacional, 1985-01-01)
      We present a study of the elastic scattering of an electron in a constant homogeneous magnetic field. The dependency of the cross section on the electron spin orientation is given. If the spin polarization is along or ...
    • The rip current hazard in Costa Rica 

      Arozarena, Isabel; Houser, Chris; Gutiérrez-Echeverría, Alejandro; Brannstrom, Christian (2015-01-31)
      Deaths from rip currents are a major hazard on global beaches, but few data are available at a national scale to support the development of appropriate intervention programs. Analysis of data from the Judicial Investigation ...
    • The rock coast of South and Central America 

      Blanco-Chao, Ramon; Pedoja, Kevin; Witt, César; martinod, joseph; Husson, Laurent; Regard, Vincent; Audin, Laurence; Nexer, Maëlle; delcaillau, bernard; Saillard, Marianne; Melnick, Daniel; Dumont, Jean Francois; Santana, Essy; Navarrete, Edison; Martillo, Carlos; PAPPALARDO, MARTA; Ayala, Luis; Araya, J.F.; Feal-Pérez, A.; Correa, D.; Arozarena-Llopis, Isabel (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 ...
    • Tsunamis Recorded in Tide Gauges at Costa Rica Pacific Coast and their Numerical Modeling 

      Chacon-Barrantes, Silvia; Gutiérrez-Echeverría, Alejandro (2017)
      Resumen Aquí realizamos un inventario de tsunamis registrado por mareógrafos en la costa del Pacífico de Costa Rica. Este documento también revela nueve registros de tsunamis que no se habían publicado antes, en el indicador ...
    • Understanding Space Weather: Solar Cycles and Magnetic Rossby Waves 

      Márquez-Artavia, Xiomara (Universidad Nacional de Costa Rica, 2019-07-31)
      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, ...
    • Validation by Molecular Dynamics of the Major Components of Sugarcane Vinasse, On a Surface of Calcium Carbonate (Calcite) 

      Rojas Alvarez, Oscar Eduardo; Nicolás Vázquez, María Inés; Oñate-Garzón, José; Arango, Carlos (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 ...
    • Variations in the geostrophic circulation pattern and thermohaline structure in the Southeast Central American Pacific 

      Brenes, Carlos; Ballestero, Daniel; Benavides, Rosario; Salazar, Juan Pablo; Murillo, Gustavo (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 ...
    • β- decay of 65Mn to 65Fe 

      Olaizola, Bruno; Fraille, L.M.; Mach, Henryk; Aprahamian, Ani; Briz, Jose Antonio; Cal-González, J.; Ghita, Dan Gabriel; Köester, U.; Kurcewicz, Wiktor; Lesher, S.R.; Pauwels, Dieter; Picado, Esteban; Poves, Alfredo; Radulov, D.; Simpson, G.S.; Udías, J.M. (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. ...
