A comprehensive method for the elastic calculation of the two-point wheel-rail contact
(Taylor & Francis, 2006)
This work shows the method developed to solve the wheel-rail contact problem via a look-up table with a three-dimensional elastic model. This method enables introduction of the two contact point effect on vehicle movement ...
Language Rights and Community Law
(ECSA Austria, 2008-11-14)
The territory of the European Union is made up of a rich and wide-ranging universe of languages, which is not only circumscribed to the "state languages". The existence of multilingualism is one of Europe’s defining ...
Prevalence and deteminants of obesity in Spanish children and young people
(Cambridge University Press, 2006-08)
Prevalence estimates of obesity in a national random sample of Spanish children and young people are presented in this paper, defined by age- and sex-specific BMI national reference standards for the 85th percentile ...
Nutrition risk in the child and adolescent population of the Basque country: the enKid Study
(Cambridge University Press, 2006-08)
Cross-sectional population studies provide valuable information for nutrition surveillance and planning intervention strategies. The enKid Study is the largest nutrition survey on the child and adolescent Spanish population ...
Global Self-Organization of the Cellular Metabolic Structure
(Public Library Science, 2008-08)
Background: Over many years, it has been assumed that enzymes work either in an isolated way, or organized in small catalytic groups. Several studies performed using "metabolic networks models'' are helping to understand ...
The Number of Catalytic Elements Is Crucial for the Emergence of Metabolic Cores
(Public Library of Science, 2009-10-19)
Background: Different studies show evidence that several unicellular organisms display a cellular metabolic structure characterized by a set of enzymes which are always in an active state (metabolic core), while the rest ...
Exact-exchange Kohn-Sham potential, surface energy, and work function of jellium slabs
(American Physical Society, 2008-08)
Exact-exchange self-consistent calculations of the Kohn-Sham potential, surface energy, and work function of jellium slabs are reported in the framework of the optimized effective potential (OEP) scheme of density functional ...
Role of occupied d states in the relaxation of hot electrons in Au
(American Physical Society, 2000-07-15)
We present first-principles calculations of electron-electron scattering rates of low-energy electrons in Au. Our full band-structure calculations indicate that a major contribution from occupied d states participating in ...
Energy loss of charged particles moving parallel to a magnesium surface
(American Physical Society, 2008-10)
We present it ab initio calculations of the electronic energy loss of charged particles moving outside a magnesium surface, from a realistic description of the one-electron band structure and a full treatment of the dynamical ...
Homogenization of Mutually Immiscible Polymers Using Nanoscale Effects: A Theoretical Study
(Hindawi Publishing Corporation, 2008)
A theoretical study to investigate homogenization of mutually immiscible polymers using nanoscale effects has been performed. Specifically, the miscibility behavior of all-polymer nanocomposites composed of linear-polystyrene ...
