Evolution of the internal load and physical condition of wheelchair basketball players during the competitive season
(Frontiers Media, 2023)
The objectives of this study were to describe differentiated perceived training and match load (dRPE-L) of wheelchair basketball (WB) players during the whole season, to analyze the evolution of players’ physical condition ...
Influencia de los tipos de agrupamiento en la competencia social de futuros docentes de Educación Física al implementar el aprendizaje cooperativo
(Universidade Federal do Rio Grande do Sul, 2023)
El objetivo de esta investigación fue comprobar la incidencia del aprendizaje cooperativo (AC) en la competencia social en función de los tipos de agrupamiento del alumnado. Participaron 53 estudiantes de tercer curso del ...
Video Image Enhancement and Machine Learning Pipeline for Underwater Animal Detection and Classification at Cabled Observatories
(MDPI, 2020-01-28)
An understanding of marine ecosystems and their biodiversity is relevant to sustainable use of the goods and services they offer. Since marine areas host complex ecosystems, it is important to develop spatially widespread ...
Gender and agency in the political learning of contentious activism. Reviewing activist models of young people in the new political cycle in the Basque Country
(Taylor and Francis, 2022-10-13)
The reproduction of gender order in young people’s learning of counter-hegemonic contentious activism may seem a contradiction in a political field seeking to transform the social order and help empower its activists. A ...
Vanadium Redox Flow Batteries: A Review Oriented to Fluid-Dynamic Optimization
(MDPI, 2020-12-31)
Large-scale energy storage systems (ESS) are nowadays growing in popularity due to the increase in the energy production by renewable energy sources, which in general have a random intermittent nature. Currently, several ...
Delamination Fracture Behavior of Unidirectional Carbon Reinforced Composites Applied to Wind Turbine Blades
(MDPI, 2021-01-27)
One of the materials that is used widely for wind turbine blade manufacturing are fiber-reinforced composites. Although glass fiber reinforcement is the most used in wind turbine blades, the use of carbon fiber allows ...

(MDPI, 2020-07-19)
Over the last few years, the advances in size and weight for wind turbines have led to the development of flow control devices. The current work presents an innovative method to model flow control devices based on a cell-set ...
What’s in a name? On the latest attempts to revive an Æther
(Springer Nature, 2023)
The development and evolution of the “Einstein–Æther Theory” (Æ-theory) shows that there is a field in cosmology where the word ether is being used again. It is unclear, however, whether this æther may be regarded in ...
A review on the valorization of CO2. Focusing on the thermodynamics and catalyst design studies of the direct synthesis of dimethyl ether
(Elsevier, 2022-08)
The direct synthesis of dimethyl ether (DME) on bifunctional catalysts is highly attractive for valorizing CO2 and syngas derived from biomass gasification and is a key process to reduce greenhouse gas emissions. DME economy ...
Phosphine-catalysed transformations of ortho- and para-quinone methides
(RSC, 2023)
Organocatalytic methodologies for the derivatization of o-QM, p-QM and the analogous aza-QM have been recently developed and involve different catalytic systems such as phosphoric acids, thioureas, squaramides, NHC carbenes ...
