DOC Transport and Export in a Dynamic Tropical Catchment
(American Geophysical Union, 2019)
Abstract Dissolved organic carbon (DOC) transport and export from headwater forests into freshwaters in highly dynamic tropical catchments are still understudied. Here we present a DOC analysis (2017) in a
pristine and ...
Tracer hydrology in a hydrometric data-limited and complex tropical mountainous region: the case of the Central American Isthmus
(European Geosciences Union, 2019)
Numerous socio-economic activities are dependent on the seasonal rainfall and groundwater recharge cycle across the Central American Isthmus. Demographic growth and unregulated land use changes resulted in extensive surface ...
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 ...
Evaluating watershed health in Costa Rican national parks and protected areas
(Springer Science and Business Media Deutschland GmbH, 2020-08-11)
Although the biodiversity of Costa Rican national parks, forests, and wetlands has been extensively surveyed, there has not
been a watershed assessment that refects their baseline water quality. Undoubtedly, the infux of ...
Headwaters drive streamflow and lowland tracer export in a large-scale humid tropical catchment
(John Wiley and Sons Ltd, 2020)
Headwaters are generally assumed to contribute the majority of water to downstream users, but
how much water, of what quality and where it is generated are rarely known in the humid tropics.
Here, using monthly monitoring ...
Green Synthesis of Gold and Silver Nanoparticles from Plant Extracts and Their Possible Applications as Antimicrobial Agents in the Agricultural Area
(MDPI AG, 2020-09-07)
Currently, metal nanoparticles have varied uses for different medical, pharmaceutical, and
agricultural applications. Nanobiotechnology, combined with green chemistry, has great potential
for the development of novel and ...
Enhancing the tolerance of Clostridium saccharoperbutylacetonicum to ligno‐ cellulosic-biomass-derived inhibitors for efficient biobutanol production by overexpressing efflux pumps genes from Pseudomonas putida
(Elsevier Ltd, 2020)
Furan aldehydes and phenolic compounds generated during biomass pretreatment can
inhibit fermentation for biofuel production. Efflux pumps actively transport small molecules out
of cells, thus sustaining normal microbial ...
Groundwater flow modeling using iMOD for Barva and Colima aquifers in the Central Valley of Costa Rica: validation of a conceptual model using tracer data
(Universidad Nacional de Salta, 2018)
A stationary numerical model of groundwater flow was developed using iMOD to better understand the recharge processes within Barva and Colima aquifers (BCS), located in the northwestern region of the Central Valley of Costa ...
