A terminal Cretaceous giant pterosaur from the French Pyrenees
1997
A very large pterosaur cervical vertebra is described from the Upper Maastrichtian deposits of Mérigon, in the foothills of the French Pyrenees. It resembles the vertebrae of Quetzalcoatlus, from the Maastrichtian of Texas, more than those of Arambourgiania, from the Maastrichtian of Jordan. The estimated wing span of the Mérigon pterosaur is close to 9 m, which makes it one of the largest known flying creatures. Giant pterosaurs still had a wide geographical distribution at the end of Maastrichtian time, which is not suggestive of a declining group, although it is difficult to obtain an accurate estimate of taxonomic diversity of terminal Cretaceous pterosaurs on the basis of available dat…
Ecological assessment of developing carbon sequestration in Shenyang, China
2012
Carbon sequestration in urban ecosystems is becoming an international climate change initiative for sustainable development. Drawing upon field work undertaken in the author's native Shenyang, China, this research reports upon the natural process of carbon sequestration from the atmosphere into urban ecosystems. The risks associated within carbon sequestration in urban ecosystems are investigated and utilised the analysis of ecological carbon cycle status and integrated climate policy with reference to the sustainable development of urban planning. The primary method of this paper is the ecologically–based life assessment of urban ecosystems relevant to tackling barriers for developing carb…
New insights into submarine tailing disposal for a reduced environmental footprint: Lessons learnt from Norwegian fjords
2021
Submarine tailing disposal (STD) in fjords from land-based mines is common practice in Norway and takes place in other regions worldwide. We synthesize the results of a multidisciplinary programme on environmental impacts of STDs in Norwegian fjords, providing new knowledge that can be applied to assess and mitigate impact of tailing disposal globally, both for submarine and deep-sea activities. Detailed geological seafloor mapping provided data on natural sedimentation to monitor depositional processes on the seafloor. Modelling and analytical techniques were used to assess the behaviour of tailing particles and process-chemicals in the environment, providing novel tools for monitoring. To…
Changes in Drop Out Intentions: Implications of the Motivational Climate, Goal Orientations and Aspects of Self-Worth across a Youth Sport Season
2021
The main objective of this work was to study the motivational antecedents of the intention to drop out of youth sport from the postulates of the achievement goal theory (AGT), placing special emphasis on the motivational climate that coaches create in their teams. Specifically, we analyzed whether changes in the perception of the motivational climate between the beginning and the end of the season predicted changes in players’ goal orientations, whether these, in turn, predicted changes in self-esteem and contingent self-esteem, and finally, whether the latter predicted the intention to drop out. Participants in the study were 552 players (Mage = 11.23, SD = 1.14), who completed the questio…
Planning, implementation and evaluation of a team-building programme in a female youth football team : an action research case study
2015
Antunes, Nuno, 2015. Planning, Implementation and Evaluation of a Team-Building Programme in a Female Youth Football Team: an Action Research Case Study. Master's Thesis in Sport and Exercise Psychology. Department of Sport Sciences, University of Jyväskylä. 55 pp It is believed that teams who work well together perform better. Frequently this requires an outside influence, which has been called team-building (TB). TB is a multivariate process and, therefore, should be studied as a multivariate issue. The current study focuses on understanding and describing the use of TB methods rather than directly investigating the effectiveness of the programme. Thus, the purpose was to describe the pla…
Géographie et sport : étudier le football dans un cadre régional
2006
D’un domaine relativement cloisonne jusqu’au lendemain de la seconde guerre mondiale, le sport est aujourd’hui une composante de la vie quotidienne d’une tres grande majorite d’individus, notamment dans les pays developpes. La croissance extraordinaire du sport n’est sans doute pas etrangere a l’ouverture de la geographie a cette activite. La multiplicite des angles d’etude (diversite des pratiques sportives) nous a oblige a opere des choix dans l’approche. Ainsi, nous focalisons nos recherches sur une pratique sportive (le football) dans un cadre regional (la Franche-Comte). Il s’agit alors de saisir l’organisation spatiale de la pratique du football dans cette region du nord-est de la Fra…
Effects of an eccentric training programme on hamstring strain injuries in women football players
2015
Summary Study aim: to test the hypothesis that an eccentric training programme applied on women football players would reduce the hamstring injury rate by improving thigh muscle balance and, particularly, hamstring strength. Material and methods: three football teams were recruited for this randomised controlled trial. They played in the first and second divisions in Spain. Players were randomised within clubs either to the intervention (eccentric exercises, n = 22) or control (control exercises, n = 21) groups, and randomisation was stratified according to previous history of thigh strains. The eccentric programme was divided into 3 phases, and each phase was composed of 7 weeks. Complianc…
Influencia de la gestación en la huella plantar
2016
Introducción. El objetivo de este estudio fue analizar la evolución de las presiones plantares, las huellas plantares así como la posición del pie durante el embarazo y tras el parto. Material y métodos. Veintitrés embarazadas fueron analizadas con el sistema Biofoot ® de plantillas instrumentadas. El sistema emplea unas plantillas con 64 sensores piezoeléctricos. Se midieron las presiones del antepié, mediopié, interno, externo y talón. Las variables de estudio de presurometría fueron: Tiempo de de apoyo (TA), la Cadencia (CA), la Presión máxima (PMax), el Tiempo de presión máxima (TPMax), el inicio del apoyo (TIAP), el fin de apoyo (TFAP), el Fin de apoyo (TFAP), el Máximo de presión medi…

ENVIRONMENTAL FOOTPRINT REDUCTION FOR WASTEWATER TREATMENT BY MULTI-OBJECTIVE OPTIMIZATION AND MODELLING
2020
The current challenge faced by researchers and managers is minimize the environmental footprint of wastewater treatment plants (WWTPs). To accomplish this goal, other than respect legal requirements, WWTPs must provide better responses regarding consumption of energy and resources, greenhouse gas (GHG) emissions, among others. The research hereby presented is based on the application of mathematical modelling with the aim to propose a framework for the minimization of WWTP’s environmental footprint towards optimization techniques. A literature review was held to gain knowledge regarding the main decision support systems (DSS) that are applied to WWTPs since they allow selecting the most app…
