Análisis de riesgo de inundación por tsunamis en Puntarenas, Costa Rica
(2001-08)
El análisis de riesgo de inundación por tsunamis en Puntarenas, Costa Rica, revela la vulnerabilidad de la región ante sismos tsunamigénicos que pudiesen ocurrir frente al Golfo de Nicoya y en la zona de subducción de ...
Diseño y caracterización de un enfriador de átomos de tipo “desacelerador Zeeman”
(2016)
Nosotros presentamos un método que utiliza simultáneamente dos modelos matemáticos, con el objetivo de optimizar el diseño de un desacelerador Zeeman, con miras a la implementación de átomos ultrafríos a la física del ...
The Hubble Constant and the Deceleration Parameter in Anisotropic Cosmological Spaces of Petrov type D
(2016-11)
In this paper the Hubble parameter and the deceleration parameter are analyzed for a group of anisotropic homogeneous solutions of the Petrov type-D. It is obtained that for the said set of solutions can be constructed a ...
Why is the electrocaloric effect so small in ferroelectrics?
(2016-05-19)
Ferroelectrics are attractive candidate materials for environmentally friendly solid state refrigeration free of greenhouse gases. Their thermal response upon variations of external electric fields is largest in the vicinity ...
The gigaelectronvolt counterpart of ver j2019+407 in the northern shell of the supernova remnant g78.2+2.1 (γ cygni)
(2016-07)
Analysis of gamma-ray emission from the supernova remnant G78.2+2.1 (γ Cygni) with 7.2 years of cumulative data from the Fermi Large Area Telescope shows a distinct hard, bright, and extended component to the north of the ...
Quantum ferroelectric instabilities in superconducting SrTiO3
(2018)
We examine the effects of strain and cation substitution on the superconducting phase of polar semiconductors near a ferroelectric quantum phase transition with a
model that combines a strong coupling theory of ...
Distribución espacial de impactos de eventos hidrometeorológicos en América Central
(2016)
América Central está expuesta a la ocurrencia de eventos hidrometeorológicos a lo largo del año y los impactos que estos pueden provocar van a estar mayormente localizados en áreas donde las variables tanto naturales como ...
Dosimeter arrangement for effective dose and isodose curves desterminations into craniofacial cavity
Disposición de dosímetros para determinaciones de curvas de dosis e isodosis efectivas en la cavidad craneofacial
(2023)
Tomographic dental imaging with cone beam computed tomography has developed so fast in Costa Rica, in the absence of investigations to determine the absorbed dose by the patients, we propose a TLD dosimeter array into RANDO ...
Electronic structure of silicon-based nanostructures
(2007-08-30)
We have developed a unifying tight-binding Hamiltonian that can account for the electronic properties of recently proposed Si-based nanostructures, namely, Si graphene-like sheets and Si nanotubes. We considered the sp3s∗ ...
Improvement of early detection of breast cancer through collaborative multi-country efforts: Medical physics component
(2018)
Purpose: The International Atomic Energy Agency (IAEA) through a Coordinated Research Project on “Enhancing
Capacity for Early Detection and Diagnosis of Breast Cancer through Imaging”, brought together a group of mammography ...
