Relationship between score and coaches’ verbal behavior
2013
Calpe V, Guzman J, Grijalbo C. Relationship between score and coaches’ verbal behaviour. J. Hum. Sport Exerc. Vol. 8, No. Proc3, pp. S728-S737, 2013. The way the coach act the most during the development of the game is meanwhile verbal behaviour directed to their players (Moreno et al., 2000), being it influenced by his own cognitions, motivations, and emotions, together with players behaviours and playing situation (Borrie, 1996; Smoll & Smith, 1989). The aim of this study was to analyse the relationship between a situational variable, the score during the game, and verbal behaviour of handball coaches in competitive situation. To do this, five coaches were analysed in five games. Two vari…
Prevención del déficit funcional en pacientes ancianos hospitalizados por enfermedad aguda : estudio preliminar de un programa de fuerza
2012
Asistimos a un envejecimiento creciente de la población, situación que supone dedicar nuestro interés a este grupo, así como a desarrollar actuaciones destinadas a mejorar su calidad de vida. Muchos de estos ancianos son ingresados y devienen en enfermos crónicos, por lo que pasan a ser considerados pacientes, y tienden a abandonar ya no solo la actividad física (AF), en caso de que existiera, sino incluso las actividades básicas de la vida diaria. Aunque sabemos de los beneficios que supone la actividad física en este grupo de población “sana”, todavía son pocos los estudios destinados a abordar el deterioro funcional y cognitivo-emocional que supone para los ancianos un ingreso hospitalar…
Physical inactivity and low fitness deserve more attention to alter cancer risk and prognosis.
2015
Abstract Sedentary lifestyle is associated with elevated cancer risk whereas regular physical activity (PA) and high cardiorespiratory fitness (CRF) have the opposite effect, with several biologic mechanisms mediating such associations. There is a need for lifestyle interventions aimed at increasing the PA levels and CRF of the general population and particularly cancer survivors. Furthermore, provocative data suggest a dose-dependent benefit of increasing levels of PA and/or CRF against cancer risk or mortality. Thus, current PA guidelines (≥150 min/wk of moderate-to-vigorous PA) may not be sufficiently rigorous for preventing cancer nor for extending cancer survivorship. Research targetin…
Assessment for the mean value total dressing method: Comparison with coupled cluster including triples methods for BF, NO+, CN+, C2, BeO, NH3, CH2, H…
1997
Limited previous experience with the mean value total dressing (MVTD) method had shown that MVTD energies for closed shell systems are generally better than CCSD(T) ones compared to FCI. The method, previously published as total dressing 2′(td-2′), is based on the single reference intermediate Hamiltonian theory. It is not a CC method but deals in a great part with the same physical effects that CC methods that incorporate amplitudes of triples such as CCSDT or its CCSDT-1n approaches. A number of test calculations comparing to diverse CC methods, as well as FCI and experiment when available, have been performed. The tests concern equilibrium energies in NH3 and CH2, equilibrium energies an…
The chemical bonds in CuH, Cu2, NiH, and Ni2 studied with multiconfigurational second order perturbation theory
1994
The performance of multiconfigurational second order perturbation theory has been analyzed for the description of the bonding in CuH, Cu2, NiH, and Ni2. Large basis sets based on atomic natural orbitals (ANOS) were employed. The effects of enlarging the active space and including the core‐valence correlation contributions have also been analyzed. Spectroscopic constants have been computed for the corresponding ground state. The Ni2 molecule has been found to have a 0+g ground state with a computed dissociation energy of 2.10 eV, exp. 2.09 eV, and a bond distance of 2.23 Å. The dipole moments of NiH and CuH are computed to be 2.34 (exp. 2.4±0.1) and 2.66 D, respectively. pou@uv.es ; merchan@…
Overview of the JET results
2015
Since the installation of an ITER-like wall, the JET programme has focused on the consolidation of ITER design choices and the preparation for ITER operation, with a specific emphasis given to the bulk tungsten melt experiment, which has been crucial for the final decision on the material choice for the day-one tungsten divertor in ITER. Integrated scenarios have been progressed with the re-establishment of long-pulse, high-confinement H-modes by optimizing the magnetic configuration and the use of ICRH to avoid tungsten impurity accumulation. Stationary discharges with detached divertor conditions and small edge localized modes have been demonstrated by nitrogen seeding. The differences in…
Full configuration interaction calculation of BeH adiabatic states.
2008
An all-electron full configuration interaction (FCI) calculation of the adiabatic potential energy curves of some of the lower states of BeH molecule is presented. A moderately large ANO basis set of atomic natural orbitals (ANO) augmented with Rydberg functions has been used in order to describe the valence and Rydberg states and their interactions. The Rydberg set of ANOs has been placed on the Be at all bond distances. So, the basis set can be described as 4s3p2d1f3s2p1d(BeH)+4s4p2d(Be). The dipole moments of several states and transition dipole strengths from the ground state are also reported as a function of the R(Be-H) distance. The position and the number of states involved in sever…
Theoretical study of the electronic spectrum of magnesium-porphyrin
1999
Multiconfigurational self-consistent field (SCF) and second order perturbation methods have been used to study the electronic spectrum of magnesium-porphyrin (MgP). An extended ANO-type basis set including polarization functions on all heavy atoms has been used. Four allowed singlet states of E1u symmetry have been computed and in addition a number of forbidden transitions and a few triplet states. The results lead to a consistent interpretation of the electronic spectrum, where the Q band contains one transition, the B band two, and the N band one. The computed transition energies are consistently between 0.1 and 0.5 too low compared to the measured band maxima. The source of the discrepan…
Strenuous exercise and the heart: are we not seeing the wood for the trees?
2014
The health benefits of regular moderate-intensity physical activity (e.g. brisk walking, jogging) are well established and include, among others, a lower risk of all-cause mortality and cardiovascular disease (CVD). Yet whether such benefits, especially with regard to CVD, are also conferred by higher exercise levels is a matter of growing controversy in the medical literature. For instance, Guash and Mont recently expressed understandable concern about the link between regular strenuous endurance exercise. 4.036 JCR (2014) Q1, 29/123 Cardiac and cardiovascular systems UEM
Detailed study of SNR G306.3–0.9 using XMM-Newton and Chandra observations
2016
Aims. We aim to study the spatial distribution of the physical and chemical properties of the X-ray emitting plasma of the supernova remnant (SNR) G306.3-0.9 in detail to obtain constraints on its ionization stage, the progenitor supernova explosion, and the age of the remnant. Methods. We used combined data from XMM-Newton and Chandra observatories to study the X-ray morphology of G306.3-0.9 in detail. A spatially resolved spectral analysis was used to obtain physical and geometrical parameters of different regions of the remnant. Spitzer infrared observations, available in the archive, were also used to constrain the progenitor supernova and study the environment in which the remnant evol…
