Biogenic silica-based microparticles obtained as a sub-product of the nanocellulose extraction process from pineapple peels
(Nature Publishing Group, 2018-07-10)
Silica in plant tissues has been suggested as a component for enhancing mechanical properties, and as a physical barrier. Pineapples present in their shell and bracts rosette-like microparticles that could be associated ...
Characterization of surface water isotope spatial patterns of Scotland
(Elsevier B.V., 2018-07-24)
The extended National Waters Inventory of Scotland (NWIS) monitoring network in combination with an extensive, supplementary low flow sampling campaign was used to create isoscapes of surface water for management purposes ...
Recovery of acetate by anion exchange with consecutive CO2-expanded methanol desorption: A model-based approach
(Elsevier BV, 2018-04-07)
Production of bio-based acetate is commonly hindered by the high costs of the downstream processing. In this
paper, a model is developed to describe a new method that recovers acetate salts using anion exchange resins,
and ...
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 ...
Groundwater and surface water connectivity within the recharge area of Guarani aquifer system during El Niño 2014–2016
(Wiley & Sons, 2018)
Recharge areas of the Guarani Aquifer System (GAS) are particularly sensitive and vulnerable
to climate variability; therefore, the understanding of infiltration mechanisms for aquifer recharge and surface run‐off generation ...
Insight into the stable isotopic composition of glacial lakes in a tropical alpine ecosystem: Chirripó, Costa Rica
(Wiley & Sons, 2018)
Tropical high‐elevation lakes are considered sentinels of global climate change. This work characterizes the hydrological conditions of tropical alpine glacial lakes located in the highlands of Chirripó, Costa Rica, using ...
Ecosystemic Assessment of Surface Water Quality in the Virilla River: Towards Sanitation Processes in Costa Rica
(Universidad Nacional (Costa Rica), 2018)
Water quality information is essential supporting decision making in water management
processes. The lack of information restricts, at some point, the implementation of adequate sanitation,
which is still scarce in ...
Isotope hydrology of a tropical coffee agroforestry watershed: Seasonal and event-based analyses
(Wiley & Sons, 2018)
Stable isotope variations are extremely useful for flow partitioning within the
hydrologic cycle but remain poorly understood throughout the tropics, particularly in
watersheds with rapidly infiltrating soils, such as ...
Isolation and Characterization of Nanocellulose Obtained from Industrial Crop Waste Resources by Using Mild Acid Hydrolysis
(Tech Science Press, 2018)
Cellulose, microcrystalline cellulose and nanocellulose were prepared from three agricultural waste resources:
pineapple leaf (PALF), banana rachis (BR), and sugarcane bagasse (SCB). Each waste resource was first converted ...
Caracterización estructural de vesículas modificadas con quitosano
(Universidad Nacional (Costa Rica), 2018-01-31)
Vesículas a base de L-α-fosfatidilcolina (PC) y mezclas de PC/fosfogliceroles fueron caracterizadas por medio de dispersión de luz dinámica (DLS), microscopía electrónica de barrido-criogénico (Cryo-SEM) y ...
