Effect of van der Waals interaction on the properties of SnS2 layered semiconductor

Nowadays, dispersion correction applied on layered semiconductors is a topic of interest. Among the known layered semiconductors, SnS2 polytypes are wide gap semiconductors with a van der Waals interaction between their layers, which could form good materials to be used in photovoltaic applications. The present work gives an approach to the SnS2 geometrical and electronic characterization using an empirical dispersion correction added to the Perdew–Burke–Ernzerhof functional and subsequent actualization of the electronic charge density using the screened hybrid Heyd–Scuseria–Ernzerhof functional using a density functional code. The obtained interlayer distance and band-gap are in good agreement with experimental values when van der Waals dispersion forces are included.

Performance variability in basketball players with intellectual impairment: Ankara World Championships 2013 analysis

The aim of the present study was to identify performance variability in basketball for players with intellectual impairment (II) and to compare it with able-bodied (AB) players. Official game statistics from the 13 games played in the Ankara World II-Basketball Championships (2013) were gathered and descriptive data, variability coefficient (VC), maximum scores and its Z-score were calculated from those players who participated at least 10 minutes per game (N = 46; guards = 10, forwards = 21, centers = 15). Results indicated higher performance variability and lower efficiency in shooting percentages and turnovers in II-players comparing with studies in ABplayers. Differences found between game positions indicated similar roles of guards, forwards and centers in II and AB-players. These findings are relevant to understand how II impact on basketball performance, which is a necessary step to develop specific eligibility systems in II-basketball according to the guidelines of the International Paralympic Committee.

Análisis de rendimiento de la Liga de Fútbol Juvenil Nacional de las Islas Baleares en la Temporada 2013/2014

Este estudio trata de realizar un análisis de rendimiento, lo más detalladamente posible, de la temporada 2013/2014 de la Liga Nacional Juvenil de Fútbol de las Islas Baleares. Para ello, se han recogido los datos de las actas publicadas en la página web de la Federación de Futbol de las Islas Baleares contemplando distintas variables categorizadas en: “relacionadas con el resultado final”, donde comprobamos la importancia de marcar primero, jugar en casa, recibir más tarjetas que el rival, recibir penalti a favor y encajar gol en periodo crítico, “relacionadas con el tiempo”, donde analizamos cuando se producen los goles, las sustituciones y las tarjetas rojas, y por último, “relación entre niveles de los equipos”, donde examinamos las variables anteriores con los 3 primeros y 3 últimos clasificados de la primera vuelta. Finalmente, se dan unas posibles reflexiones sobre por qué suceden dichas variables.
