Understanding Space Weather: Solar Cycles and Magnetic Rossby Waves
(Universidad Nacional de Costa Rica, 2019-07-31)
El objetivo de esta investigación es explorar si existe una relación entre las ondas magnéticas de Rossby rápidas o lentas y ciertas observaciones de la actividad solar de largo y muy largo plazo (meses, ...
Raman spectroscopy as a tool to evaluate oxygen effects on the response of polymer gel dosimetry
(Elsevier, 2019-05-06)
Currently, advanced dosimeters like polymer gels are capable of obtaining reliable and accurate 3D dose distributions from correlations with the different polymerization degrees induced by incident radiation. Samples of ...
Deforestation processes in the livestock territory of La Vía Láctea, Matagalpa, Nicaragua
(Taylor and Francis Ltd., 2019-05-04)
Land-use change is considered one of the main causes of environmental
degradation. Thus, its analysis will allow stakeholders to make reasonable
decisions for land management. The objective of the present study was ...
Cladocera (Crustacea, Branchiopoda) of a temporary shallow pond from northern Colombia
(Universidad Nacional Mayor de San Marcos, 2019)
Eighteen species of cladocerans are recorded from a temporary pond in northern
Colombia; 12 of these records are new for La Guajira Department: Diaphanosoma
brevireme Sars, 1901, D. dentatum Herbst, 1968, Sarsilotona ...
Infragravity wave energy partitioning in the surf zone in response to wind-sea and swell forcing
(MDPI AG, 2019)
An alongshore array of pressure sensors and a cross-shore array of current velocity and
pressure sensors were deployed on a barred beach in southwestern Australia to estimate the relative
response of edge waves and leaky ...
Influence of the Madden–Julian oscillation on Costa Rican mid-summer drought timing
(John Wiley and Sons Ltd, 2019)
The Central American mid-summer drought (MSD) is the decline of precipitation
during the middle of the wet season (July and August) over Central America and
southern Mexico. It affects agriculture and favours the initiation ...
Electrochemical Characterization of Mancozeb Degradation for Wastewater Treatment Using a Sensor Based on Poly (3,4-ethylenedioxythiophene) (PEDOT) Modified with Carbon Nanotubes and Gold Nanoparticles
(MDPI AG, 2019)
Mancozeb is a worldwide fungicide used on a large scale in agriculture. The active component and its main metabolite, ethylene thiourea, has been related to health issues. Robust, fast, and reliable methodologies to quantify ...
Properties of low-lying states in 65Co from lifetime measurements
(American Physical Society, 2019)
The low-energy structure of Co65 was studied by means of γ-and fast-timing spectroscopy at the ISOLDE/CERN facility. The known level scheme of Co65 populated following the β-decay of Fe65 was expanded. The experimental ...
Coastal currents in the Eastern Gulf of Tehuantepec from coastal altimetry
(Advances in Space Research, 2018-06-02)
we study the seasonal and interannual variability of the coastal currents along the eastern shelf of the Gulf of Tehuantepec. We use sea level from coastal altimetry distributed by the Centre de Topographie des Oceans et ...
Dairy wastewater treatment by anaerobic fixed bed reactors from laboratory to pilot-scale plant: A case study in Costa Rica operating at ambient temperature
(Springer, 2013)
The effect of hydraulic retention time in a range from 1.0-5.5 days was evaluated in a laboratory scale anaerobic fixed bed reactor packed with a hybrid material composed of tire rubber and zeolite. Under
these conditions, ...
