Glacial chronology, environmental changes and implications for human occupation during the upper Pleistocene in the eastern Cantabrian Mountains
(2014-10-14)
Interest in the evolution of Pleistocene glaciers, environmental change and human occupation in southern
Europe is now growing thanks to the availability of fresh dating in different mountains. The demise of Neanderthals
in ...
Hybrid materials based on azopolymer and sol-gel synthesized silver-containing titanium oxide nanoparticles with photoinduced birefringence
(The Royal Society of Chemistry, 2015-01-28)
The main goal of this work was the development of novel nanocomposite films with different optical
properties. A non-toxic water soluble azopolymer was modified with TiO2 nanoparticles and silver containing TiO2 nanoparticles. ...
Hybrid acrylic/CeO2 nanocomposites using hydrophilic spherical and high aspect ratio CeO2 nanoparticles
(Royal Society of Chemistry, 2014-10-15)
A dispersion of CeO2 nanoparticles and nanorods stabilized with nitrilotriacetic acid (NTA) and a 4,4′-azobis(4-cyanovaleric acid) (V-501) initiator has been used to initiate the emulsion polymerization of acrylic monomers, ...
Growth and stable isotope signals associated with drought‐related mortality in saplings of two coexisting pine species
(Springer, 2013-06-25)
Drought-induced events of massive tree mortality appear to be increasing worldwide. Species-specific vulnerability to drought mortality may alter patterns of species diversity and affect future forest composition. We have ...
Hardness, grainsize and porosity formation prediction on the Laser Metal Deposition of AISI 304 stainless steel
(Elsevier, 2018-08-14)
[EN] The presented numerical model solves the heat and mass transfer equations in the Laser Metal Deposition process and based on the evolution of the thermal field predicts the grainsize, the resulting hardness and evaluates ...
“Hacer mayorazgo infalible de consejeros y ministros graves”. El Señorío de Vizcaya y el proyecto de fundar un colegio en Salamanca (1638-c.1660)
(Instituto Figuerola de Historia y Ciencias Sociales, Universidad Carlos III de Madrid, 2019-11-29)
[ES] En un contexto de predominio de la cultura letrada y del derecho, la presencia de magistrados naturales u originarios de un territorio en los principales órganos jurisdiccionales de la Corona podía propiciar ventajas ...
Grigorchuk-Gupta-Sidki groups as a source for Beauvile surfaces
(EMS Press, 2020-06-25)
If G is a Grigorchuk-Gupta-Sidki group defined over a p-adic tree, where p is an odd prime, we study the existence of Beauville surfaces associated to the quotients of G by its level stabilizers stG(n). We prove that if G ...
High conductance values in pi-folded molecular junctions
(Nature Publishing, 2017-05-18)
Folding processes play a crucial role in the development of function in biomacromolecules. Recreating this feature on synthetic systems would not only allow understanding and reproducing biological functions but also ...
High-Performance Magnetic Activated Carbon from Solid Waste from Lignin Conversion Processes. 1. Their Use As Adsorbents for CO2
(ACS Publications, 2017-03-09)
[EN] Lignin is naturally abundant and a renewable precursor with the potential to be used in the production of both chemicals and materials. As many lignin conversion processes suffer from a significant production of solid ...
Geomatics techniques applied to glaciers, rock glaciers, and icepatches in Spain (1991-2012)
(Published by Taylor & Francis on behalf of the Swedish Society for Anthropology and Geography, 2014)
At present there is a wide variety of geomatic
techniques available to determine the dynamics of glaciers,
rock glaciers and ice patches. Between 1991 and 2012, different
geomatic techniques – total station, global ...
