Three-dimensional analysis of fracture, corrosion and wear surfaces
(PERGAMON-ELSEVIER SCIENCE LTD, 2010)
A brief look at the history of fractography has shown a recent trend in the quantification of topographic parameters through the use of three-dimensional reconstruction techniques, which associate SEM stereoscopy and ...
Nanostructured titanium alloy surfaces for enhanced osteoblast response: A combination of morphology and chemistry
(2020-02-15)
This study is part of a new trend in the metallic biomaterials field that searches to use the titanium beta alloys with recognized bulk and surface properties for better biological response. Ti15Mo alloy (wt%) had it surface ...
Analysis of the Effect of Surface Hydrogen Concentration on the Hydrogen Oxidation Reaction: Voltammetry vs. Steady State
(Research Trends, 2017-07)
Starting from the modelling of the processes involved in the hydrogen oxidation reaction, the present work provides an explanation about the origin of the differences observed between the polarization curves obtained by ...
Regional hydro-climatic changes in the Southern Amazon Basin (Upper Madeira Basin) during the 1982–2017 period
(Elsevier, 2019-12)
Study region: Upper Madeira Basin (975,500 km2) in Southern Amazonia, which is suffering a biophysical transition, involving deforestation and changes in rainfall regime. Study focus: The evolution of the runoff coefficient ...
Assessing recent trends in high-latitude Southern Hemisphere surface climate
(Nature Publishing Group, 2016-10)
Understanding the causes of recent climatic trends and variability in the high-latitude Southern Hemisphere is hampered by a short instrumental record. Here, we analyse recent atmosphere, surface ocean and sea-ice observations ...
Uso de sombras na correção do efeito vinhete
(Universidade Federal do Paraná, 2014-03-01)
When registering spectral radiance from surface targets, digital numbers recorded by the imagery sensor may vary. Such variation causes imperfections on the images coming from aerial surveys. Variation in the image brightness ...
Temporal variability of the Buenos Aires, Argentina, urban heat island
(Springer Wien, 2012-01)
This paper describes the statistical characteristics and temporal variability of the urban heat island (UHI) intensity in Buenos Aires using 32-year surface meteorological data with 1-h time intervals. Seasonal analyses ...
Ion fractions in the scattering of hydrogen on silicon surfaces
(Wiley, 2005-12)
We present a theoretical calculation of the resonant charge-exchange process occurring in H0 scattering by Si(100)2 × 1 surfaces. In the atom-surface interacting system the core states of the surface atoms are included and ...
