El desarrollo rural en la vertiente atlántica del País Vasco: un balance
(INGEBA, 2000)
[EUS] Artikulo honetan euskal isurialde atlantiarreko bi munitzipioetan martxan jarritako garapen lokaleko proiektuak aztertzen dira. Esperientzia horiek beherapen industrialean dagoen eskualde batean landa garapenak izan ...
The IRYSS-COPD appropriateness study: objectives, methodology, and description of the prospective cohort
(BioMed Central, 2011-11)
Background: Patients with chronic obstructive pulmonary disease (COPD) often experience exacerbations of the disease that require hospitalization. Current guidelines offer little guidance for identifying patients whose ...
Effect of Molecular Flexibility on the Nematic-to-Isotropic Phase Transition for Highly Biaxial Molecular Non-Symmetric Liquid Crystal Dimers
(MDPI, 2011-10)
In this work, a study of the nematic (N)-isotropic (I) phase transition has been made in a series of odd non-symmetric liquid crystal dimers, the alpha-(4-cyanobiphenyl-4'-yloxy)-omega-(1-pyrenimine-benzylidene-4'-oxy) ...
Agent based modeling of energy networks
(Elsevier, 2014-04-03)
Attempts to model any present or future power grid face a huge challenge because a power grid is a complex system, with feedback and multi-agent behaviors, integrated by generation, distribution, storage and consumption ...
An adaptive sliding mode control law for the power maximization of the wind turbine system
(IEEE, 2011)
The actual wind turbines are provided with adjustable speed generators, like the double feed induction generator, that are capable to work in variable speed operations. One of the main advantage of adjustable speed generators ...
Sliding mode control strategy for variable speed wind turbines
(IEEE, 2009)
The efficiency of the wind power conversions systems can be greatly improved using an appropriate control algorithm. In this work, a robust control for variable speed wind power generation that incorporates a doubly feed ...
Object oriented simulation of hybrid renewable energy systems focused on supervisor control
(IEEE, 2009)
With eyes focused on simulation the authors review some of the main topics of Hybrid Renewable Energy Systems (HRES). Then they describe an Object Oriented model of a simple example of one of such systems, a micro-grid, ...
Three-dimensional growth as multicellular spheroid activates the proangiogenic phenotype of colorectal carcinoma cells via LFA-1-dependent VEGF: implications on hepatic micrometastasis
(BioMed Central, 2008-10)
Background: The recruitment of vascular stromal and endothelial cells is an early event occurring during cancer cell growth at premetastatic niches, but how the microenvironment created by the initial three-dimensional ...
Phosphorylation of the carboxy-terminal domain of histone H1: effects on secondary structure and DNA condensation
(Oxford University Press, 2008-08)
Linker histone H1 plays an important role in chromatin folding. Phosphorylation by cyclin-dependent kinases is the main post-translational modification of histone H1. We studied the effects of phosphorylation on the secondary ...
Detection of Atomic Scale Changes in the Free Volume Void Size of Three-Dimensional Colorectal Cancer Cell Culture Using Positron Annihilation Lifetime Spectroscopy
(Public Library of Science, 2014-01-02)
Positron annihilation lifetime spectroscopy (PALS) provides a direct measurement of the free volume void sizes in polymers and biological systems. This free volume is critical in explaining and understanding physical and ...
