The nature of Miocene Amazonian epicontinental embayment: High-frequency shifts of the low-gradient coastline
(Geological Society of AmericaUS, 2007-11)
A sedimentological and ichnological data set that covers the Lower-Upper Miocene sedimentary series of western Amazonian foreland basin indicates that widespread, restricted marine ingressions shaped western Amazonia ...

Decodificación de señales digitales utilizando SDR como herramienta complementaria para mejorar la comprobación técnica del espectro
(Universidad de los AndesMaestría en Ingeniería Electrónica y de ComputadoresFacultad de IngenieríaDepartamento de Ingeniería Eléctrica y Electrónica, 2020)
La identificación automática de señales será fundamental para la gestión, vigilancia y control de las radiocomunicaciones cuando sea una realidad la asignación dinámica de espectro a través de tecnologías como la Radio ...
Endotoxin exposure during sensitization to Blomia tropicalis allergens shifts TH2 immunity towards a TH17-mediated airway neutrophilic inflammation: role of TLR4 and TLR2
(Public Library of ScienceSan Francisco, 2013)
Experimental evidence and epidemiological studies indicate that exposure to endotoxin lipopolysaccharide (eLPS) or other TLR agonists prevent asthma. We have previously shown in the OVA-model of asthma that eLPS administration ...
Catalisadores à base de Cu, Zn, Al e Ce aplicados à reação deslocamento gás-água
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQ, 2014-03-26)
The water gas-shift reaction (WGS) is an important step in the production process and purification of H2 from hydrocarbon. Commercially, to overcome the thermodynamic and kinetic limitations, this reaction occurs in two ...
DFT study of methanol adsorption on PtCo(111)
(Elsevier Science, 2017-10-31)
Methanol adsorption on PtCo(111) surface at low coverage is studied using Density Functional Theory (DFT) calculations without and with van der Waals corrections. We investigated the PtCo FCT alloy surface with a uniform ...
