Guía de mediación pedagógica para aprendizajes comunitarios: comités de agua transfronte- rizos, Costa Rica - Nicaragua : pedagogía social, estrategias para la optimización del uso del agua para consumo humano en las comunidades de La Trocha e Isla Chica en los Chiles, Alajuela
(2021)
El equipo de profesores y profesoras de la Universidad Nacional y la Universidad de Costa Rica que elaboró esta guía conforma el proyecto de extensión y acción social universitaria: “Pedagogía social: estrategias para la ...
Diet and Leukocyte Telomere Length in a Population with Extended Longevity: The Costa Rican Longevity and Healthy Aging Study (CRELES)
(2021)
Elderly Costa Ricans have lower mortality rates compared to their counterparts from
developed countries. Reasons for this survival advantage are not completely known. In the present
study, we aimed to identify dietary ...
Relationship between species richness of excavator birds and cavity–adopters in seven tropical forests in costa rica
(2009)
The abundance of wood cavities is thought to be a limiting factor for bird species that depend on these cavities for nesting. Thus, it is expected that number of cavity adopters correlates with number of cavity excavators ...
Well-posedness and discrete analysis for advection-diffusion-reaction in poroelastic media
(2021)
We analyse a PDE system modelling poromechanical processes (formulated in mixed form using the solid deformation, fluid pressure, and total pressure) interacting with diffusing and reacting solutes in the medium. We ...
New neotropical species of Phyllachorales based on molecular, morphological, and ecological data
(2018-09-14)
Species of tropical tar spot fungi (Phyllachorales, Ascomycota) are obligate biotrophic plant
parasitic fungi associated with living leaves of a wide range of families of host plants, mainly in
tropical and subtropical ...
Rapid shift in microbial community structure in a neutral hydrothermal hot spring from Costa Rica
(2020)
In this work, we characterize the geochemistry and microbial community of Bajo las Peñas, a neutral (pH 6.5-7.4), hot spring (T = 62.0-68.0°C) located near Turrialba Volcano, Costa Rica. The microbiota at its two sources ...
Collateral effects of microplastic pollution on aquatic microorganisms: An ecological perspective
(2018-12-05)
Microplastics (MP) provide a unique and extensive surface for microbial colonization in aquatic ecosystems. The formation of microorganism-microplastic complexes, such as biofilms, maximizes the degradation of organic ...
Propargylation of Carbonyl Compounds: An Efficient Method for the Synthesis of Homopropargyl Alcohols
(1998)
Controlled dilithiation of allene, with two equivalents of n-butytlithium, produces the propargyl dianion 5. The latter couple efficiently with carbonyl compounds to produce homopropargyl alcohols in high yields.
The countries and languages that dominate biological research at the beginning of the 21st century
(Revista de Biolología Tropical 53 (1-2): 283-294, 2005, 2005)
Traditionally, studies of scientific productivity are biased in two ways: they are based on Current
Contents, an index centered in British and American journals, and they seldom correct for population size, ...
On the standard form of the Bloch equation
(1979-03)
The requirement is often made in non-equilibrium statistical mechanics
that a transport equation should be derived as that which governs the
subdynamics relative to a (small) part of a (large) conservative
dynamical ...
