Optical properties of metals: Infrared emissivity in the anomalous skin effect spectral region
(American Institute of Physics, 2014-09-07)
When the penetration depth of an electromagnetic wave in a metal is similar to the mean free path of the conduction electrons, the Drude classical theory is no longer satisfied and the skin effect becomes anomalous. Physical ...
Spectral emissivity of copper and nickel in the mid-infrared range between 250 and 900 ºC
(Elsevier, 2014-01-15)
A study on the radiative properties of two pure metals, copper and nickel, using a high accuracy radiometer is carried out. Their spectral emissivity between 3 and 21 μm and its dependence on emission angle and temperature ...
Base catalysed depolymerization of lignin: Influence of organosolv lignin nature
(2014-07)
Three different lignins obtained from olive tree pruning by organosolv processes
(acetosolv, formosolv and acetosolv/formosolv) were depolymerized by alkaline hydrolysis in a batch reactor to produce high value added ...
Behavior And Ultrastructure Of Human Bone Marrow-Derived Mesenchymal Stem Cells Immobilized In Alginate-Poly-L-Lysine-Alginate Microcapsules
(Taylor & Francis, 2014-04-24)
Context: Human bone marrow mesenchymal stem cells (hBM-MSCs) show a great promise for the treatment of a variety of diseases. Despite the previous trials to encapsulate hBM-MSCs in alginate-poly-l-lysine-alginate (APA) ...
Bioanalytical chromatographic method validation according to current regulations, with a special focus on the non-well defined parameters limit of quantification, robustness and matrix effect
(Elsevier, 2014-08-01)
Method validation is a mandatory step in bioanalysis, to evaluate the ability of developed methods in providing reliable results for their routine application. Even if some organisations have developed guidelines to define ...
Blood miRNA expression pattern is a possible risk marker for natalizumab-associated progressive multifocal leukoencephalopathy in multiple sclerosis patients
(Sage, 2014-05-22)
Background: Natalizumab has shown its efficacy in reducing multiple sclerosis (MS) relapses and progression of disability; however, it has been associated with an increased risk of developing progressive multifocal ...
Sediment toxicity and bioaccumulation assessment in abandoned Copper and Mercury mining areas of the Nalón River basin (Spain)
(Springer, 2014-11-06)
Sediment toxicity and metal bioaccumulation were assessed at sites affected by historical copper (Cu)
and mercury (Hg) mining activities in the Nalón River basin, Asturias, Spain. Toxicity assessment of stream sediments ...
Domesticidad y familia: ambigüedad y contradicción en los modelos de feminidad en el franquismo
(Universidad de Alicante, 2014)
La instauración de la dictadura franquista significó la consolidación de un modelo de
familia que, mediante la combinación de elementos católicos y falangistas, se convir-
tió en la base legitimadora del nuevo régimen. ...
Combate epistemológico, combate de poder: del tetelesménon al dókos
(Universidad de Sevilla, 2014)
El artículo se remonta a la Grecia Arcaica para analizar algunos de los cambios sociales y epistemológicos más significativos que se produjeron y que resultaron decisivos para el posterior desarrollo de la cultura. Para ...
