Quantifying the benefits of a solar home system-based DC microgrid for rural electrification
(2019)Off-grid solar home systems (SHSs) currently constitute a major source of providing basic electricity needs in un(der)-electrified regions of the world, with around 73 million households having benefited from off-grid solar ... -
Quantitation by enzyme-immunoassay of antibodies against Bothrops myotoxins in four commercially-available antivenoms
(1991)An enzyme-immunoassay (EIA) for the quantitation of antibodies against myotoxins present in the venoms of Bothrops asper (Costa Rica), B. atrox (Colombia) and B. moojeni (Brazil), was developed. This EIA was utilized for ... -
Quantitation of myonecrosis induced by myotoxin a from prairie rattlesnake (Crotalus viridis viridis) venom
(1982)Using a pure myotoxin (myotoxin a) isolated from prairie rattlesnake Crotalus viridis viridis) venom, a comparison between two methods for quantitating myonecrosis in mice was made. Measurement of creatine kinase (CK) ... -
Quantitative genetic analysis of anxiety trait in bipolar disorder
(2017)Background:Bipolar disorder type I (BPI) affects approximately 1% of the world population. Although geneticinfluences on bipolar disorder are well established, identification of genes that predispose to the illness has ... -
Quantitative Physiology Approaches to Understand and Optimize Reducing Power Availability in Environmental Bacteria
(2015-06-04)The understanding of how carbon fluxes are distributed through a metabolic network offers an overview of the pathways that a given microorganism uses to produce energy, reducing power, and biomass. These invaluable data ... -
Quantum electrodynamics in external fields from the spin representation
(1994-07)Systematic use of the infinite-dimensional spin representation simplifies and rigorizes several questions in quantum field theory. This representation permutes "Gaussian" elements in the fermion Fock space, and is necessarily ... -
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 ... -
Quantum gauge models without classical Higgs mechanism
(2010-09-15)We examine the status of massive gauge theories, such as those usually obtained by spontaneous symmetry breakdown, from the viewpoint of causal (Epstein-Glaser) renormalization. The BRST formulation of gauge invariance in ... -
Quantum symmetry groups of noncommutative spheres
(2001-08)We show that the noncommutative spheres of Connes and Landi are quantum homogeneous spaces for certain compact quantum groups. We give a general construction of homogeneous spaces which support noncommutative spin geometries. -
Quantum Theory of Triboelectricity
(2020-10-30)We propose a microphysical theory of the triboelectric effect by which mechanical rubbing separates charges across the interface between two materials. Surface electrons are treated as an open system coupled to two baths, ... -
Lo que depara la pandemia al nuevo presidente
(2022-04-05)El 9 de mayo la flamante administración encontrará el país navegando sobre una nueva ola pandémica. Hacia el 8 de junio los nuevos diagnósticos de Covid-19 podrían ser 3.000 diarios. -

(2022)Este importante documento histórico: “Que Fue y que es la Estación Experimental Agrícola Fabio Baudrit Moreno según Yo…”, ganador del concurso sobre biografías del personal administrativo de la “Fabio Baudrit” efectuado ... -
Lo que la ciudad anhela “ver”: Desarrollo urbano, nuevas tecnologías y espacios públicos en San José (Costa Rica)
(2012)El texto gira en torno a las recientes transformaciones del espacio público en la ciudad de San José, capital de Costa Rica. Estos cambios estimulan la emergencia de un nuevo “sistema de visualidad”, correspondiente a las ... -
Lo que se bailó en Costa Rica. Actividad dancística ejecutada en los teatros capitalinos de Costa Rica durante el año 2015
(2016-07)Este texto pretende, como resumen, dar una idea de cuál fue la principal actividad dancística de creadores nacionales y extranjeros que se ejecutó en los teatros capitalinos de Costa Rica durante el 2015. -
Queilitis actínica: Reporte de tres casos y revisión de literatura
(2018)La queilitis actínica (QA) es un desorden potencialmente maligno del labio inducido por la exposición crónica a la luz ultravioleta, que afecta principalmente al bermellón del labio inferior de personas adultas y de piel ... -
QUEMADURA ELÉCTRICA DE PARED ABDOMINAL COMO CAUSA DE PERFORACIÓN DE INTESTINO DELGADO
(2011-05-01)A 49 years old male patient who suffered anelectric burn by direct contact with a currentwhile manipulating a metallic object ispresented. He showed minor dermal manifestations of 5% burnt body surface areaand on the seventh ... -
Quenched distributions for the maximum, minimum and local time of the Brox diffusion
(2021)After leaving fixed the environment, which is called the quenchend case, we give explicitly the distribution function of the maximum and the minimum of the Brox diffusion at first time it reaches a barrier. We also give ...
