Influence of creep forces on the risk of derailment of railway vehicles
(Taylor & Francis, 2009)
The derailment mechanism in a railway vehicle is a complex mechanical phenomenon which has been, and still is, the subject of intense research activity due to the serious consequences it can entail. Since Nadal deduced his ...
Dynamic optimization of track components to minimize rail corrugation
(Elsevier, 2009-01)
In this paper, the influence on corrugation of the most significant track parameters has been examined. After this parametric study, the optimization of the track parameters to minimize the undulatory wear growth has been ...
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 ...
A multi-gene analysis strategy identifies metabolic pathways targeted by trans-10, cis-12-conjugated linoleic acid in the liver of hamsters
(Cambridge University Press, 2009-08-28)
In mice, hepatic functions can be greatly affected by dietary trans-10, cis-12-conjugated linoleic acid (CLA). However, this phenomenon has been less documented in hamsters. In the present study, male hamsters were fed two ...
Synthetic applications of intramolecular aza-Wittig reaction for the preparation of heterocyclic compound
(Bentham Science Publishers, 2009)
[EN] A review focused on recent advances in intramolecular aza-Wittig reaction of phosphazenes with several carbonyl or analogous compounds is reported. Phosphazenes afford intramolecular aza-Wittig reaction with different ...
Systematic review of pharmacological treatments in fragile X syndrome
(BioMed Central, 2009-10-13)
Background: Fragile X syndrome (FXS) is considered the most common cause of inherited mental retardation. Affected people have mental impairment that can include Attention Deficit and/or Hyperactivity Disorder (ADHD), ...
The COMT Val158 Met polymorphism as an associated risk factor for Alzheimer disease and mild cognitive impairment in APOE 4 carriers
(BioMed Central, 2009-09)
Background: The aim of this study is to examine the influence of the catechol-O-methyltranferase (COMT) gene (polymorphism Val158 Met) as a risk factor for Alzheimer's disease (AD) and mild cognitive impairment of amnesic ...
Flexible Strain-Tension Calculation Method for Gap-type Overhead Conductors
(IEEE, 2009-07)
Commercially available sag-tension programs give good results for most practical applications. However, they have some limitations concerning gap-type conductors. A separate aluminum and core creep calculation is needed ...
Identification of Horse Chestnut Coat Color Genotype Using SNaPshot
(Biomed Central, 2009-12-16)
BACKGROUND: The Cantabrian Coast horse breeds of the Iberian Peninsula have mainly black or bay colored coats, but alleles responsible for a chestnut coat color run in these breeds and occasionally, chestnut horses are ...
Thin Magnetically Soft Wires for Magnetic Microsensors
(MDPI, 2009-11)
Recent advances in technology involving magnetic materials require development of novel advanced magnetic materials with improved magnetic and magneto-transport properties and with reduced dimensionality. Therefore magnetic ...
