Chirripó Hydrological Research Site: advancing stable isotope hydrology in the Central American Páramo
(2020-01-25)
The Chirripó Hydrological Research Site (CHRS) is located within the Chirripó National Park, Costa Rica (between 3,100-3,820 m asl) whereby ~100 km2 are covered by Páramo, a high‐elevation tropical grassland ecosystem. A ...
Revisiting the fundamentals of p-nitrophenol analysis for its application in the quantification of lipases activity. A graphical update
(Universidad Nacional (Costa Rica), 2020-07-31)
p-Nitrophenol (pNP) is a widely used compound for analytical determinations of several esterases (EC. 3.1.1.X), including lipases (E.C. 3.1.1.3). Most enzymatic measurements employ pNP derivatives such as ...
Environmental isotope applications in Latin America and the Caribbean region
(Taylor & Francis, 2020-11)
This Special Issue illustrates the use of environmental isotopes in studying and assessing hydrogeological and ecohydrological issues in the Latin America and the Caribbean (LAC) region. The issue includes twenty selected ...
Tracing water sources and fluxes in a dynamic tropical environment from observations to modeling
(Frontiers in Earth Science, 2020-11-06)
Tropical regions cover approximately 36% of the Earth’s landmass. These regions are home to 40% of the world’s population, which is projected to increase to over 50% by 2030 under a remarkable climate variability scenario ...
Bayesian estimates of the mean recharge elevations of water sources in the Central America region using stable water
(Elsevier, 2020)
Study region: Central America. Study focus: Knowledge of the mean recharge elevation (MRE) of water resources is important where water resources are vulnerable. The purpose of this study was to develop and apply a Bayesian ...
Hydrological dataset of a sub-humid continental plain basin (Buenos Aires, Argentina)
(Elsevier, 2020)
The Chaco-Pampean Plain (Argentina) is the strongest eco- nomic region and the most inhabited in the country, comprising approximately 66% of the country’s population (26,500 million) [1] . In this region, surface slopes ...
Rainfall, groundwater, and surface water isotope data from extreme tropical cyclones (2016-2019) within the Caribbean Sea and Atlantic Ocean basins
(Elsevier, 2020-06)
Under a changing climate, projections estimate that over the next thirty years, extreme Tropical Cyclones (TCs) will increase in frequency, with two to three times more Category 4 and 5 hurricanes in the Atlantic basin ...
Self-assembly study of type I collagen extracted from male Wistar Hannover rat tail tendons
(BioMed Central Ltd, 2020-11-23)
Background: Collagen, the most abundant protein in the animal kingdom, represents a promising biomaterial for
regenerative medicine applications due to its structural diversity and self-assembling complexity. Despite ...
Biosensors for the Detection of Bacterial and Viral Clinical Pathogens
(MDPI AG, 2020-12-04)
Biosensors are measurement devices that can sense several biomolecules, and are widely
used for the detection of relevant clinical pathogens such as bacteria and viruses, showing outstanding
results. Because of the latent ...
Fungal biosynthesis of lignin-modifying enzymes from pulp wash and Luffa cylindrica for azo dye RB5 biodecolorization using modeling by response surface methodology and artificial neural network
(Elsevier, 2020-06-04)
This study demonstrates the evaluation between the artificial neural network technique coupled to the genetic
algorithm (ANN-GA) and the response surface methodology (RSM) for prediction of Reactive Black 5 (RB5)
decolorization ...
