Body image and body composition: comparisons of young male elite soccer players and controls
(Human Kinetics, 2008)
[EN] The purpose of this study was to evaluate body composition and body image (perception and satisfaction) in a group of young elite soccer players and to compare the data with those of a control group (age and BMI ...
Predictors of Major Infections in Systemic Lupus Erythematosus
(Biomed Central, 2009-07-15)
Introduction Infections commonly complicate the course of systemic lupus erythematosus (SLE). Our aim is to investigate the clinical predictors of major infections in patients with SLE.
Methods A nested case-control ...
Anti-Inflammatory and Immunosuppressive Drugs and Reproduction
(Biomed Central, 2006-05-11)
Rheumatic diseases in women of childbearing years may necessitate drug treatment during a pregnancy, to control maternal disease activity and to ensure a successful pregnancy outcome. This survey is based on a consensus ...
Wheel-rail wear index prediction considering multiple contact patches
(Elsevier, 2009-06)
This paper shows a new wheel-rail contact model specially suited to obtain wear indexes between wheel and rail when the vehicle negotiates tight curves. The model presented in the paper enables introduction of the two ...
Equivalent Conicity and Curve Radius Influence on Dynamical Performance of Unconventional Bogies. Comparison Analysis
(Taylor and Francis, 2004)
In this paper the dynamic behaviour of several unconventional bogies is compared. The study takes into account the radius of the curve and the maximum level of wear allowed to the wheels. Ranges of conicities and curve ...
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 ...
A Review of Estimation of Distribution Algorithms in Bioinformatics
(Biomed Central, 2008-09-11)
Evolutionary search algorithms have become an essential asset in the algorithmic toolbox for solving high-dimensional optimization problems in across a broad range of bioinformatics problems. Genetic algorithms, the most ...
Cohomologically Kähler manifolds with no Kähler metrics
(Hindawi Publishing Corporation, 2003)
We show some examples of compact symplectic solvmanifolds, of
dimension greater than four, which are cohomologically
Kähler and do not admit Kähler metric since their
fundamental groups cannot be the fundamental group ...
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 ...
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 ...
