Block copolymer concentration gradient and solvent effects on nanostructuring of thin epoxy coatings modified with epoxidized styrene-butadiene-styrene block copolymers
(ACS, 2012-01-27)
The gradient on block copolymer concentration through film thickness as well as the effects of casting solvents used on the nanostructuring of a thermosetting epoxy coating modified with an epoxidized poly(styrene-b-buta ...
Framework for the design and analysis of steel fiber reinforced self-compacting concrete structures
(Elsevier, 2012-05-31)
This research focuses on the structural applications of steel fiber reinforced concrete (SFRC). Various fibers are first studied, in order to choose the most suitable type in accordance with the specific application. A ...
Comparison between experimental values and standards on natural stone masonry mechanical properties
(Elsevier, 2012-03-01)
[EN] The research presented in this paper investigates the mechanical properties under compressive loads of a natural stone masonry. Selected materials and arrangement are typical from the Romanesque period, the main ...
Effects of a putative antidepressant with a rapid onset of action in defeated mice with different coping strategies
(Elsevier, 2012-04-22)
There is evidence suggesting that stressful social events may result in depressive-like disorders, but the development of these disorders depend on the way in which people cope with stress. Although antidepressants are ...
Effect of alkaline and autohydrolysis processes on the purity of obtained hemicelluloses from corn stalks
(Elsevier, 2012)
[EN]A study of the potential of autohydrolysis and alkaline extraction processes from corn stalks was performed
for high purity hemicellulose extraction. The influence of process parameters on the purity of
obtained ...
Glycine Adsorption at Nonstoichiometric (010) Hydroxyapatite Surfaces: A B3LYP Study
(ACS, 2012-06-12)
The adsorption of glycine on the Ca-rich and P-rich HA(010) nonstoichiometric surfaces has been studied at B3LYP level using a polarized triple-ζ basis set within periodic boundary conditions. Although the Ca-rich and ...
General aspects, hierarchical controls and droop methods in microgrids: A review
(Elsevier, 2012-10-17)
Distributed generation is emerging as a new technology for supplying the increasing demand for electricity. Microgrids are attracting a great deal of attention since they integrate distributed generation in the main grid ...
High Availability Automation Networks: PRP and HSR Ring Implementations
(IEEE, 2012-05)
The work developed has as basis the networks/protocols described in the standard IEC 62439-3 Industrial automation networks - High availability automation networks: PRP and HSR. The similarities of both networks and a ...
Inactivation of encapsulated cells and their therapeutic effects by means of TGL triple-fusion reporter/biosafety gene
(Elsevier, 2012-11-19)
The immobilization of cells within alginate-poly-l-lysine-alginate (APA) microcapsules has been demonstrated to be an effective technology design for long term delivery of therapeutic products. Despite promising advances, ...
Raman spectroscopy assisted with XRF and chemical simulation to assess the synergic impacts of guardrails and traffic pollutants on urban soils
(Wiley, 2012-11-01)
Urban soils are potential reservoirs of toxic metals as a consequence of traffic emissions. Sources like brake linings, tyres, road pavement, exhaust fumes, guardrail, traffic signals and other galvanised steel structures ...
