A Randomized Controlled Trial Protocol to Test The Efficacy of a Dual-TaskMulticomponent Exercise Program in the Attenuation of Frailty in Long-Term Nursing Home Residents: Aging-ONDUAL-TASK Study
(Springer Nature, 2019-01-08)BACKGROUND: The purpose of the Aging-ONDUAL-TASK study is to determine if a supervised dual-task program carried out in long-term nursing homes is able to attenuate frailty in a greater extent than the same multicomponent ... -
A Rapid Routine Methodology Based on Chemometrics to Evaluate the Toxicity of Commercial Infant Milks Due to Hazardous Elements
(Springer, 2022)The toxicity and the health risk assessment associated to the presence of some hazardous elements (HEs) in dried (infant formula and powdered) milks due to manufacturing and packaging process, raw materials used, environmental ... -
A rapid sedimentary response to the Paleocene-Eocene Thermal Maximum hydrological change: New data from alluvial units of the Tremp-Graus Basin (Spanish Pyrenees)
(Elsevier, 2022-03-01)A massive emission of light carbon about 56 Ma, recorded in marine and terrestrial sediments by a negative carbon isotope excursion (CIE), caused a short-lived (similar to 170 kyr) global warming event known as the ... -
A rational fraction polynomials model to study vertical dynamic wheel-rail interaction
(Elsevier, 2012-04)This paper presents a model designed to study vertical interactions between wheel and rail when the wheel moves over a rail welding. The model focuses on the spatial domain, and is drawn up in a simple fashion from track ... -
A RE Methodology to achieve Accurate Polygon Models and NURBS Surfaces by Applying Different Data Processing Techniques
(MDPI, 2020-11-12)The scope of this work is to present a reverse engineering (RE) methodology to achieve accurate polygon models for 3D printing or additive manufacturing (AM) applications, as well as NURBS (Non-Uniform Rational B-Splines) ... -
A Real Application of an Autonomous Industrial Mobile Manipulator within Industrial Context
(MDPI, 2021-05-27)In modern industry there are still a large number of low added-value processes that can be automated or semi-automated with safe cooperation between robot and human operators. The European SHERLOCK project aims to integrate ... -
A real time sliding mode control for a wave energy converter based on a wells turbine
(Elsevier, 2018-06-18)Due to the nonlinear dynamics and uncertainties usually present in wave energy conversion systems, the efficiency of these devices can be enhanced employing a robust control algorithms. Wave energy converters are constructed ... -
