Spatial and temporal variability of satellite-derived sea surface temperature in the southwestern Atlantic Ocean
(Pergamon-Elsevier Science Ltd, 2010-04)
Mean fields, seasonal cycle, and interannual variability of the Southwestern Atlantic Ocean (SAO) sea surface temperature (SST) distribution are examined during an 18-year (January 1985-December 2002) period by means of ...
Spatial and temporal trends and flow dynamics of glyphosate and other pesticides within an agricultural watershed in Argentina
(Society of Environmental Toxicology and Chemistry, 2017-12)
In the present study, we evaluated the spatial and temporal trends of current-use pesticides in surface water and sediments as well as their relationship with hydrological stream dynamics within the agricultural watershed ...
Trend and recovery of the total ozone column in South America and Antarctica
South America is one of the most vulnerable areas to stratospheric ozone depletion; consequently, an increased amount of UV radiation reaches the Earth's surface in this region. In this study, we analyzed the long-term ...
The Nanocrystalline SnO2–TiO2 System‒Part II: Surface Energies and Thermodynamic Stability
The thermodynamic stability of nanocrystalline SnO2–TiO2 solid solutions was studied experimentally. Microcalorimetry of water adsorption revealed a systematic decrease in the surface energy with increasing Ti4+ content ...
Segregation trends of the metal alloys Mo-Re and Mo-Pt on HfO2: A first-principles study
(Amer Inst PhysicsMelvilleEUA, 2006)
Long-term population trends of the Red-legged Cormorant Phalacrocorax gaimardi on the Argentine coast
(Cambridge University Press, 2015-06)
The world population of Red-legged Cormorant Phalacrocorax gaimardi is reasonably small and has showed rapid declines. In Argentina, this species breeds in 13 localities and is considered as 'Endangered' by the national ...
Au13-nAgn clusters: a remarkably simple trend
(Royal Soc Chemistry, 2015)
The planar to three dimensional transition of Au13-nAgn clusters is investigated. To do so the low lying energy configurations for all possible concentrations (n values) are evaluated. Many thousands of possible conformations ...
