Friction torque in four contact point slewing bearings: Effect of manufacturing errors and ring stiffness
(Elsevier, 2017-02-24)
This work outlines a procedure for the determination of the interferences between balls and raceways in four contact
point slewing bearings due to manufacturing errors. The procedure is applied to a particular case and ...
Bioanalytical chromatographic method validation according to current regulations, with a special focus on the non-well defined parameters limit of quantification, robustness and matrix effect
(Elsevier, 2014-08-01)
Method validation is a mandatory step in bioanalysis, to evaluate the ability of developed methods in providing reliable results for their routine application. Even if some organisations have developed guidelines to define ...
A sequential process for hydrogen production based on continuous HDPE fast pyrolysis and in-line steam reforming
(Elsevier, 2016-07-15)
A continuous process has been developed consisting in the flash pyrolysis (500 ºC) of high density polyethylene (HDPE) in a conical spouted bed reactor (CSBR) followed by steam reforming in a fluidized bed reactor (Ni ...
Analysis of the DCB test of angle-ply laminates including residual stresses
(Elsevier, 2017-03-14)
[ES] Se propone un nuevo método para obtener la tasa de liberación de energía mediante la prueba de doble viga en voladizo para laminados de capas angulares. Se estudian dos secuencias diferentes, simétrica y antisimétrica. ...
Baseline tissue concentrations of metal in aquatic oligochaetes: field and laboratory approaches.
(Elsevier, 2017-02-04)
Metal tissue residue evaluation in benthic macroinvertebrates is an important component of an integrated approach to ecological risk assessment of metals and metalloids in the Nalón River basin (North Spain), where historic ...
DNA methylation epigenotypes in breast cancer molecular subtypes
(BioMed Central, 2010-09-29)
Introduction: Identification of gene expression-based breast cancer subtypes is considered a critical means of prognostication. Genetic mutations along with epigenetic alterations contribute to gene-expression changes ...
An Improved Meshing Method for Shape Optimization of Aerodynamic Profiles Using Genetic Algorithms
(WILEY, 2008)
One of the basic problems in fluid dynamics shape optimization is mesh generation. When analysis is performed using the finite element method, meshes of sufficient quality need to be constructed automatically. This work ...
Blood miRNA expression pattern is a possible risk marker for natalizumab-associated progressive multifocal leukoencephalopathy in multiple sclerosis patients
(Sage, 2014-05-22)
Background: Natalizumab has shown its efficacy in reducing multiple sclerosis (MS) relapses and progression of disability; however, it has been associated with an increased risk of developing progressive multifocal ...
