Dry season plant water sourcing in contrasting tropical ecosystems of Costa Rica
(John Wiley & Sons (Estados Unidos), 2023)
Tracer-aided studies to understand plant water uptake sources and dynamics in tropical
ecosystems are limited. Here, we report the analysis of dry season source water
uptake patterns of five unique ecosystems of Costa ...
New Botanical Anxiolytics for Use in Companion Animals and Humans
(Springer (Alemania), 2017-11)
As part of our ongoing research into botanical therapies for anxiety disorders,
the neotropical vine Souroubea sympetala was chosen for study as a phytochemical discovery
strategy focusing on rare Central American plant ...
Saneamiento de aguas residuales mediante humedales artificiales en el Museo de Cultura Popular de la Universidad Nacional
(Universidad Nacional (Costa Rica), 2013-06)
El cumplimiento de los Objetivos de Desarrollo del Milenio en términos de acceso sostenible al saneamiento requiere incrementar el desarrollo de programas de investigación que promuevan opciones tecnológicas simples y de ...
Aprendizaje activo, “nueva” metodología aplicada en secundaria para la enseñanza de la química ¿Solución para cambiar el paradigma?
(Universidad Nacional (Costa Rica), 2019-06)
Debido a los desafíos que enfrenta la educación científica actualmente y la gran importancia que esta tiene pata el progreso del país, es que el Ministerio de Educación Publica (MEP) ha venido haciendo esfuerzos múltiples ...
Hydrometeorological Factors Controlling the Stable Isotopic Composition of Precipitation in the Highlands of South Ecuador
(American Meteorological Society (Estados Unidos), 2022-07)
Knowledge about precipitation generation remains limited in the tropical Andes due to the lack of water stable isotope (WSI) data. Therefore, we investigated the key factors controlling the isotopic composition of precipitation ...
Exploring Dissolved Organic Carbon Variations in a High Elevation Tropical Peatland Ecosystem: Cerro de la Muerte, Costa Rica
(Frontiers Media (Suiza), 2022-01)
Tropical peatlands are distributed mainly in coastal lowlands; however high elevation regions exhibit a large prevalence of small and fragmented peatlands that are mostly understudied. Artificial drainage of peatlands to ...
Water stable isotopes reveal the hydrological response of Costa Rican glacial lakes to climate variability
(Elsevier (Países Bajos), 2022)
Los lagos generalmente se consideran una fuente de información clave para comprender el paleoclima. Aquí usamos estable.
Isótopos de agua (δ2H y δ18O) en un lago glacial tropical de gran altitud para informar sobre la ...
Orientation effect in poly (butylene succinate) fibers
(Polymers & Polymer Composites vol.11 no.1 51-56 2003, 2003)
Fibers of poly (butylene succinate) (PBS) were prepared using a single screw extruder at various take-up speeds. Changes in fiber structure, morphology and physical properties were investigated using sonic velocity ...
Isotopic composition and major ion concentrations of national and international bottled waters in Costa Rica
(Elsevier (Países Bajos), 2021)
Global bottled water consumption has largely increased (14.35 billion gallons in 2020) [1], [2], [3], [4], [5] during the last decade since consumers are demanding healthier and safer forms of rehydration. Bottled water ...
Data Descriptor: Daily observations of stable isotope ratios of rainfall in the tropics
(Springer Nature (Alemania), 2019)
We present precipitation isotope data (δ2H and δ18O values) from 19 stations across the tropics collected
from 2012 to 2017 under the Coordinated Research Project F31004 sponsored by the International
Atomic Energy Agency. ...
