Offensive zones in beach volleyball: differences by gender

Gender differences in anthropometric and athletic properties (e.g. strength) as well as the different net heights (2.24 vs. 2.43 m) on the same field size (8x16 m) would be reflected in the game. The literature about differences between male and female playing characteristics in beach volleyball is scarce. Therefore, the aim of this study was to analyse the differences by gender in the use of offensive zones. Study participants were 20 players (10 female and 10 male) who took part in the European Beach Volleyball Championship 2005 and 2006. Video recordings were made of the 659 points in eight matches played. The beach volleyball court was divided into six zones (z1 to z6). The results showed that men and women use different offensive zones and also were different in the percentages of ball out (15.53 and 27.38% respectively). Concretely, men players used more 1, 2, 4 and 5 zones and women 1 and 5 zones. A few differences were observed in the percentage the ball to the net (7.73 and 5.35% respectively). An understanding of the use of offensive zones is relevant to establish specific tactical training patterns for beach volleyball.

Transport in magnetically ordered Pt nanocontacts

Pt nanocontacts, like those formed in mechanically controlled break junctions, are shown to develop spontaneous local magnetic order. Our density functional calculations predict that a robust local magnetic order exists in the atoms presenting low coordination, i.e., those forming the atom-sized neck. We thus find that the electronic transport can be spin polarized, although the net value of the conductance still agrees with available experimental information. Experimental implications of the formation of this new type of nanomagnet are discussed.

Magnetic and orbital blocking in Ni nanocontacts

We address the fundamental question of whether magnetoresistance (MR) of atomic-sized contacts of nickel is very large because of the formation of a domain wall (DW) at the neck. Using ab initio transport calculations we find that, as in the case of nonmagnetic electrodes, transport in Ni nanocontacts depends very much on the orbital nature of the electrons. Our results are in agreement with several experiments in the average value of the conductance. On the other hand, contrary to existing claims, DW scattering does not account for large MR in Ni nanocontacts.

Comisión de plan de estudios de la titulación de Ingeniería Técnica de Telecomunicaciones, especialidad en Sonido e Imagen de la EPS

La red docente de la Comisión de plan de estudios de la titulación de Ingeniería Técnica de Telecomunicación, especialidad en Sonido e Imagen de la EPS ha realizado durante el curso 2007/08 un estudio de los objetivos y competencias del futuro título de grado, así como el análisis y diseño de la posible estructura en bloques y asignaturas obligatorias en la que se podría distribuir dicho título. El estudio toma como base los resultados obtenidos en redes de cursos anteriores (ver memoria de redes 2005/06 y 2006/07), las cuales estaban orientadas al diseño curricular dentro del marco de los créditos ECTS para la convergencia al Espacio Europeo de Educación Superior, y sobre todo, se basa en la experiencia de los propios participantes en trabajos o redes previas. El objetivo principal de este proyecto es el diseño curricular del futuro título de grado en Ingeniería de Telecomunicación en Sonido e Imagen, directamente relacionada con la actual Ingeniería Técnica de Telecomunicación, especialidad en Sonido e Imagen, que se imparte en la Universidad de Alicante. Para ello se han seguido las pautas generales establecidas por el Real Decreto de ordenación de Enseñanzas Universitarias Oficiales (BOE, 30 de octubre de 2007), así como otros documentos elaborados por el Colegio Oficial de Ingenieros Técnicos de Telecomunicación y la Comisión de Universidades de Ingeniería Técnica de Telecomunicación.
