Payments for Ecosystem Services (PES) in the face of external biophysical stressors
(Elsevier, 2014-11-24)
Economic instruments such as Payments for Ecosystem Services (PES) schemes are increasingly promoted to protect ecosystems (and their associated ecosystem services) that are threatened by processes of local and global ...
Psychosocial Adjustment Of Spanish Emigrants And Non- Emigrants
(Elsevier, 2014-06-02)
[EN]The aim of this study was to verify whether psychological adjustment, social support and mental health are better among Spanish non-emigrants than Spanish who immigrate to other parts of Europe, and to analyse the ...
Origin and nature of coke in ethanol steam reforming and its role in deactivation of Ni/La2O3-αAl2O3 catalyst
(ACS, 2019-07-22)
Deactivation of Ni/La2O3-αAl2O3 catalyst in the ethanol steam reforming (ESR) was studied in order to establish the optimal conditions for maximizing H2 production and achieving a steady behaviour. The ESR reactions were ...
Thermally-responsive biopolyurethanes from a biobased diisocyanate
(Elsevier, 2015-09)
In this work, segmented biopolyurethanes with thermally-activated shape-memory properties were synthesized and characterized. All the employed starting materials were derived from renewable sources. The macrodiol, which ...
Time consistent expected mean-variance in multistage stochastic quadratic optimization: a model and a matheuristic
(Springer, 2019)
In this paper, we present a multistage time consistent Expected Conditional Risk Measure for minimizing a linear combination of the expected mean and the expected variance, so-called Expected Mean-Variance. The model is ...
Overhang constraint for topology optimization of self-supported compliant mechanisms considering additive manufacturing
(Elsevier, 2019-04)
This work presents a computational procedure for direct integration of Topology Optimization and Additive Manufacturing (AM) technologies for compliant mechanisms design. Many topologically optimized geometries present ...
Thin film nanocomposites based on SBM triblock copolymer and silver nanoparticles: morphological and dielectric analysis
(WILEY-VCH, 2017-07-20)
Hybrid organic/inorganic thin film nanocomposites based on poly(styrene)-b-poly(butadiene)-b-poly(methyl methacrylate) (SBM) triblock copolymer and silver nanoparticles (Ag) have been prepared and characterized. In order ...
Threats and Limitations of Terrestrial Broadcast Attacks
(IEEE, 2018-03)
[EN] The DVB standard does not mandate the use of authentication and integrity protection for transport streams. This allows malicious third parties to replace legitimate broadcasts by overpowering terrestrial transmissions. ...
Solving math and science problems in the real world with a computational mind
(NAER, 2014)
This article presents a new paradigm for the study of Math and
Sciences curriculum during primary and secondary education. A
workshop for Education undergraduates at four different
campuses (n=242) was designed to ...
The use of traditional media for public communication about medicines: a systematic review of characteristics and outcomes
(Routdledge. Taylor & Francis Group, 2019)
A systematic review was conducted to identify, appraise, and synthesize data from original research investigating the use of traditional media for public communication about medicines. Databases were searched for studies ...
