(2018)Objetivo: Indagar la duración de la lactancia materna exclusiva en una comunidad urbana y una rural de Costa Rica. Método: Se realizó un estudio descriptivo transversal sobre el inicio y duración de la lactancia materna ... -
Duración de la lactancia materna, alimentación combinada y riesgo para la salud en jóvenes costarricenses
(2022)Objetivo: examinar la asociación entre la duración de la lactancia materna y la alimentación mixta con la obesidad, riesgo cardiometabólico, grasa corporal, conductas de riesgo dietéticas y de actividad física en niños ... -
Duración de la reincidencia y sus factores asociados en la población penitenciaria de Costa Rica
(2021)Este estudio pretende medir la reincidencia y los factores asociados que podrían explicar su duración por medio de un análisis de sobrevivencia, para esto se consideran los datos de las personas que han ingresado al Sistema ... -
Duty, power and management in the actual Costa Rican public education system
(2013-12-19)This article proposes, firstly, the challenges faced by the Costa Rican Management of Education by the Information and Communications Technology (ICT); and the Society of Information and Knowledge (SIK). Subsequently, ... -
Dye‐sensitized Devices: Photovoltaic and Photoelectrolytic Applications
(2018-11)Dye‐sensitized approach along with stability and surface robustness in titanium dioxide (TiO2) against photocorrosion and degradation has been widely studied and applied in several important applications. This chapter ... -
DynACof: A process-based model to study growth, yield and ecosystem services of coffee agroforestry systems
(2020)The DynACof model was designed to model coffee agroforestry systems and study the trade-offs to e.g. optimize the system facing climate changes. The model simulates net primary productivity (NPP), growth, yield, mortality, ... -
Dynamic Analysis of Modified Structural Systems
(1986-06)A set of methods is developed to determine the changes in frequencies and mode shapes of a structure resulting from modifications of the structure. These modifications can involve an increase in the number of degrees of ... -
Dynamic Analysis of Modified Structural Systems
(1987-05-20)The subject of this study is the development of a set of methods for the calculation of the changes in the frequency of vibration and mode shape of a structure due to changes in the physical system. Such changes may consist ... -
Dynamic Properties of Modified Systems
(1985-08-19)A set of methods is presented for convenient calculation of the changes in the frequency and shape of any mode of undamped vibration of a structure due to changes in the parameters of the system. Previously reported methods ... -
Dynamical delimitation of the Central American Dry Corridor (CADC) using drought indices and aridity values
(2019)The Central American Dry Corridor (CADC) is a sub-region in the isthmus that is relatively drier than the rest of the territory. Traditional delineations of the CADC’s boundaries start at the Pacific coast of southern ... -
Dynamical downscaling of historical climate over CORDEX Central America domain with a regionally coupled atmosphere–ocean model
(2018-08)The climate in Mexico and Central America is influenced by the Pacific and the Atlantic oceanic basins and atmospheric conditions over continental North and South America. These factors and important ocean–atmosphere coupled ... -
Dynamical theory for the battery's electromotive force
(2021-03-23)We propose a dynamical theory of how the chemical energy stored in a battery generates the electromotive force (emf). In this picture, the battery's half-cell acts as an engine, cyclically extracting work from its underlying ... -
Dynamics in benthic community composition and influencing factors in an upwelling-exposed coral reef on the Pacific coast of Costa Rica
(2015-11-24)Seasonal upwelling at the northern Pacific coast of Costa Rica offers the opportunity to investigate the effects of pronounced changes in key water parameters on fine-scale dynamics of local coral reef communities. This ... -
Dynamics of a two-dimensional discrete-time SIS model
(2012-04-26)We analyze a two-dimensional discrete-time SIS model with a non-constant total population. Our goal is to determine the interaction between the total population, the susceptible class and the infective class, and the ... -
