Un ejercicio de arqueología urbana: relación cronológica de materiales en veredas y construcciones conexas
(Odlanyer Hernández de Lara, 2015-07)
La arqueología urbana suponía que las veredas de Buenos Aires ya estaban totalmente destruidas para cualquier tipo de estudio sistemático. La excavación de varias cuadras en un barrio no central permitió observar la ...
Cellular and Molecular Mechanisms of MT1-MMP-Dependent Cancer Cell Invasion
(Annual Reviews, 2016-10)
Metastasis is responsible for most of cancer-associated deaths. Accumulating evidence based on 3D migration models has revealed a diversity of invasive migratory schemes reflecting the plasticity of tumor cells to switch ...
Numerical investigation of the double-arcing phenomenon in a cutting arc torch
(American Institute of Physics, 2014-07)
A numerical investigation of the double-arcing phenomenon in a cutting arc torch is reported. The dynamics of the double-arcing were simulated by using a two-dimensional model of the gas breakdown development in the ...
Lanthanum-based perovskites as catalysts for the ozonation of selected organic compounds
(Elsevier, 2013-08)
The ozonation of two model compounds (oxalic acid and dye C. I. Reactive Blue 5) was carried out in the presence of La containing perovskites prepared by the citrate method. With the exception of LaFe0.9Cu0.1O3, all samples ...
Cobalt and Iron Complexes with N-heterocyclic Ligands as Pyrolysis Precursors for Oxygen Reduction Catalysts
(Pergamon-Elsevier Science Ltd, 2015-08)
Cobalt and Iron based catalysts for the Oxygen Reduction Reaction (ORR) are a promising alternative to the use of Pt in Polymer Electrolyte Fuel Cells (PEMFC). A systematic study on the influence of the nitrogenated ligand ...
Estudio morfológico del género Classopollis (Pflug) Pocock & Jansonius (Cretácico, Argentina)Morphological study of the genus Classopollis (Pflug) Pocock & Jansonius (Cretaceous, Argentina)
(Sociedade Brasileira de Paleontologia, 2014-06)
The present paper analyses different species belonging to the genus Classopollis (Pfl ug) Pocock & Jansonius with scanning electron microscopy (SEM). The material was collected from surface sections and boreholes of ...
Dengue virus capsid protein usurps lipid droplets for viral particle formation
(Public Library of Science, 2009-10)
Dengue virus is responsible for the highest rates of disease and mortality among the members of the Flavivirus genus. Dengue epidemics are still occurring around the world, indicating an urgent need of prophylactic vaccines ...
Validation of remotely-sensed evapotranspiration and NDWI using ground measurements at Riverlands, South Africa
(Water Research Commission, 2014-02)
Quantification of the water cycle components is key to managing water resources. Remote sensing techniques and products have recently been developed for the estimation of water balance variables. The objective of this study ...
Accretion vs. colliding wind models for the gamma-ray binary LS I +61 303: an assessment
(EDP Sciences, 2007-12)
Context. LS I +61 303 is a puzzling Be/X-ray binary with variable gamma-ray emission up to TeV energies. The nature of the compact object and the origin of the high-energy emission are unclear. One family of models invokes ...
SUR1 Receptor Interaction with Hesperidin and Linarin Predicts Possible Mechanisms of Action of Valeriana officinalis in Parkinson.
(Frontiers, 2016-08)
Parkinson's disease (PD) is one of the most common neurodegenerative disorders. A theoretical approach of our previous experiments reporting the cytoprotective effects of the Valeriana officinalis compounds extract for PD ...
