Electronic modeling of a PEMFC with logarithmic amplifiers
(Elsevier, 2015-02-04)
The main purpose of this project has been to simulate the behavior of a PEM-type fuel cell working in a stationary regimen using an equivalent circuit (EC). The EC designed with Multisim circuit design software reproduces ...
Experiments on a lab scale TES unit using eutectic metal alloy as PCM
(Elsevier, 2015-05)
The behavior of a magnesium and zinc eutectic metal alloy used as thermal energy storage (TES) material is tested in a
laboratory scale TES unit. The TES unit consists of two concentric tubes with the central tube surrounded ...

(2015-12-01)
El Magnetismo Molecular y Fotoquímica son las áreas de investigación en las que se centra el trabajo presentado en esta tesis. El objetivo de este trabajo no sólo ha sido la preparación de complejos de coordinación con ...
Tailoring Mechanical Properties of Rigid Polyurethane Foams by Sorbitol and Corn Derived Biopolyol Mixtures
(ACS, 2015-10-28)
Sorbitol arises to be a strong candidate for renewably sourced polyol synthesis. Moreover, processes for extracting sorbitol directly from cellulosic materials are effective, and materials such as agroforestry residues ...
Reputation features for trust prediction in social networks
(Elsevier, 2015-05-08)
Trust prediction in Social Networks is required to solve the cold start problem, which consists of guessing a Trust value when the truster has no direct previous experience on the trustee. Trust prediction can be achieved ...
Suitability of discrete choice experiments for landscape management under the European Landscape Convention
(Elsevier, 2015-02-26)
[EN] Landscapes throughout the world are increasingly being altered as a result of human actions and natural processes, therefore necessitating urgent management. Acknowledging this situation, the European Landscape ...
Usefulness of 1H NMR in assessing the extent of lipid digestion
(Elsevier, 2015-01-30)
Proton Nuclear Magnetic Resonance (1H NMR) is proved to be, for the first time, a very useful technique in monitoring the extent of lipid hydrolysis in digestion processes. Sunflower oil and minced fish flesh, as model ...
L1 use in EFL task-based interaction: a matter of gender?
(De Gruyter, 2015-07-11)
This study analyzes the impact of gender on first language (L1) use and the functions it served during English as foreign language (EFL) task-based interaction. Participants were all Spanish EFL learners who worked in ...
Importance of the spectral emissivity measurements at working temperature to determine the efficiency of a solar selective coating
(Elsevier, 2015-09-01)
The total emissivity of the absorbing surfaces is a critical parameter in the calculation of the radiative thermal losses in solar thermal collectors. This is because the radiative heat losses have a significant economic ...
A functional variant that affects exon-skipping and protein expression of SP140 as genetic mechanism predisposing to multiple sclerosis
(Oxford University Pres, 2015-10-01)
Several variants in strong linkage disequilibrium (LD) at the SP140 locus have been associated with multiple sclerosis (MS), Crohn's disease (CD) and chronic lymphocytic leukemia (CLL). To determine the causal polymorphism, ...
