The effect of contextual variables on the attacking style of play in professional soccer
2021
The aim of this paper was to investigate the interactive effects of contextual variables on the attacking style of play in professional soccer. 5849 team possessions from 40 random matches from Spanish La Liga and English Premier League 2017-2018 were analysed by means of multidimensional observation. Multilevel multivariate logistic regressions showed that home teams had higher odds of implementing fast attacks (p<.05) and lower odds of implementing direct attacks (p<.05) than combinative attacks. High-ranked teams presented lower odds of using direct attacks (p<.05) than combinative attacks in comparison with low-ranked teams, while playing against high-ranked opponents decreased the prob…
Judo as a tool for social integration in adolescents at risk of social exclusion: A pilot study
2020
Purpose: Social policies of the advanced countries have begun to incorporate sport to speak on manifestations of social exclusion, as tool to reach out to young people, strengthen their identity or enhance self-esteem vulnerable groups. Judo can be a good tool for the fulfilment of this purpose because has a philosophy and educational practice that contains much of the core competencies of the educational system. The aim of this study is to analyse the incidence of judo practice in changing attitudes, values, norms and capabilities across organizational forms as a means of enhancing socialization in their interventions with young people at risk of social exclusion. Material/Methods: We used…
Sonication-Induced Modification of Carbon Nanotubes: Effect on the Rheological and Thermo-Oxidative Behaviour of Polymer-Based Nanocomposites.
2018
The aim of this work is the investigation of the effect of ultrasound treatment on the structural characteristics of carbon nanotubes (CNTs) and the consequent influence that the shortening induced by sonication exerts on the morphology, rheological behaviour and thermo-oxidative resistance of ultra-high molecular weight polyethylene (UHMWPE)-based nanocomposites. First, CNTs have been subjected to sonication for different time intervals and the performed spectroscopic and morphological analyses reveal that a dramatic decrease of the CNT's original length occurs with increased sonication time. The reduction of the initial length of CNTs strongly affects the nanocomposite rheological behavio…
Social psychological aspects of ACL injury prevention and rehabilitation: An integrated model for behavioral adherence
2017
Managing rehabilitation for ACL injury is dependent on uptake of, and compliance with, medical and safety recommendations. In this paper, we propose a multi-theory model that integrates self-determination theory and the theory of planned behavior to identify the motivational determinants ACL injury prevention and management behaviors and the processes involved. nonPeerReviewed
Technical, tactical and spatial indicators related to goal scoring in European elite soccer
2020
The aim of this study was to describe the technical, tactical and spatial indicators related to goal scoring in elite European soccer, considering the type of defence and the positioning of the opponent. For the analysis, 8 tactical dimensions related to the final actions in 380 sequences that led to goal during the UEFA Champions League were evaluated by observational methodology. 75.9% of the goals were scored from open play and 24.1% were scored from set pieces. Collective actions produced 51.6% of the total goals while individual actions produced 10.5% of goals. Regarding the penultimate action, crosses were more frequent against organized defences, while passes in behind the defence, o…
Tuning of Emission Wavelength of CaS:Eu by Addition of Oxygen Using Atomic Layer Deposition
2021
| openaire: EC/H2020/820423/EU//S2QUIP | openaire: EC/H2020/834742/EU//ATOP | openaire: EC/H2020/965124/EU//FEMTOCHIP Atomic layer deposition (ALD) technology has unlocked new ways of manipulating the growth of inorganic materials. The fine control at the atomic level allowed by ALD technology creates the perfect conditions for the inclusion of new cationic or anionic elements of the already-known materials. Consequently, novel material characteristics may arise with new functions for applications. This is especially relevant for inorganic luminescent materials where slight changes in the vicinity of the luminescent centers may originate new emission properties. Here, we studied the lumines…
Test-retest reliability of survey items on ownership and use of physical activity trackers
2019
Background: Researchers are interested in using digital tools, such as physical activity trackers (PAT), to promote and measure physical activity. PAT is a fast-growing research area that measures movement therefore, reliable questions on the ownership and use of PATs among adolescent populations need to be developed. Objective: The aim of this study was to conduct an intra-rater test-retest reliability study on PAT survey items used for surveillance purposes among young adolescents in ownership and use of smartphone applications (apps) and heart rate monitors (HRM). Methods: Young adolescents (N = 755; 11-, 13-, and 15-year-olds) in the Olomouc region of the Czech Republic were recruited t…
Taste receptors signalling
2010
International audience
Piecing together the taste signaling puzzle
2010
International audience; The identification of the genes coding for bitter, umami, sweet and sour taste receptors has provided us with unique tools to investigate the gustatory system. As a consequence, tremendous progress towards our understanding of the functional organization of the peripheral taste system has been achieved over the past decade. In particular, key components of the taste receptors signaling cascades have been identified as well as populations of chemosensory cells in the olfactory, respiratory and digestive systems expressing taste receptors. Besides sharing receptors and signaling molecules (gustducin, phospholipase-C b2…) with taste bud cells, these cells display a simi…
Thermo-Mechanical Behaviour of Flax-Fibre Reinforced Epoxy Laminates for Industrial Applications
2015
The present work describes the experimental mechanical characterisation of a natural flax fibre reinforced epoxy polymer composite. A commercial plain woven quasi-unidirectional flax fabric with spun-twisted yarns is employed in particular, as well as unidirectional composite panels manufactured with three techniques: hand-lay-up, vacuum bagging and resin infusion. The stiffness and strength behaviours are investigated under both monotonic and low-cycle fatigue loadings. The analysed material has, in particular, shown a typical bilinear behaviour under pure traction, with a knee yield point occurring at a rather low stress value, after which the material tensile stiffness is significantly r…
