A hydrogen economy is needed, in order to resolve current environmental and energy-related problems. For the introduction of hydrogen as an important energy vector, sophisticated materials are required. This paper provides a brief overview of the subject, with a focus…

Focus of the study is to verify the incidence of performance analysis data of bodily communication in volleyball, in order to evaluate the benefits of approving bodily communication points for a new categorization of data points. In detail, the purpose…

The aim of this study was to analyse the interaction between game actions in high-level handball and verbal behaviour performed by the coach. For this purpose, a match of the 1st National Division of male Spanish handball was analysed. The…

This study was designed to identify the injuries of professional women windsurfers, from their anatomical location, type of sport, context when they occurred, type of injury, the time of inactivity as a result of the same, the type of health…

We report the results of an experimental-theoretical study on the stopping power of ZrO2 films for swift H and He ion beams. The experiments, using the Rutherford Backscattering technique, were done for protons with incident energies in the range 200–1500…

We have determined “effective” Bethe coefficients and the mean excitation energy of stopping theory (I-value) for multiwalled carbon nanotubes (MWCNTs) and single-walled carbon nanotube (SWCNT) bundles based on a sum-rule constrained optical-data model energy loss function with improved asymptotic properties.…

The energy-loss straggling of zirconia (ZrO2) and alumina (Al2O3) has been experimentally determined for proton and alpha-particle beams mainly by means of the Rutherford backscattering technique and in some few cases using the transmission method. The incident energies of the…

Previous studies in basketball performance have tended to assess differences between winners and losers of games. This methodology does not consider the fluctuating nature of scoring within games. Consequently winning and losing performance for each quarter of 26 games of…

Team performance in rugby has typically been assessed through the comparison of winning and losing teams, however, the distinction between winning and losing was used as the sole independent variable. Thus potential confounding variables that may affect performance such as…

In most sports, it is found that the important performance indicators (PI’s) vary from coach to coach. Therefore, if sets of PI’s can be identified and clear operational definitions defined, there is significant scope/benefit for consultancy and research, particularly in…
