Esta investigación propone un «armazón conceptual» desde el que explicar el éxito en el desempeño de la conducta «tiro libre» del deporte baloncesto. Se expone la importancia de personalizar la variable «Sistema de Concentración» para el éxito de la conducta, y se muestra un método eficaz para lograr dicha personalización. En esta investigación se comprueba la efectividad de un determinado método de entrenamiento de tiros libres frecuentemente utilizado por los entrenadores. Se determina la variación de valores en las distintas variables del citado armazón conceptual, y la efectividad del método de entrenamiento en el porcentaje de tiros libres conseguidos en competiciónThis investigation proposes a framework that explains the success in the free throws behavior. The investigation explains the importance about personalizing the variable «Concentration System» in every player for the success in the behavior, and shows an efficient method to achieve personalization. In the investigation we test the effectiveness of a very popular trainig system method. We test the values variation at the framework, and the effectiveness of that training system method in the free throws competition averag

Dark Left-Right Gauge Model: SU(2)_R Phenomenology

In the recently proposed dark left-right gauge model of particle interactions, the left-handed fermion doublet $(\nu,e)_L$ is connected to its right-handed counterpart $(n,e)_R$ through a scalar bidoublet, but $\nu_L$ couples to $n_R$ only through $\phi_1^0$ which has no vacuum expectation value. The usual R parity, i.e. $R = (-)^{3B+L+2j}$, can be defined for this nonsupersymmetric model so that both $n$ and $\Phi_1$ are odd together with $W_R^\pm$. The lightest $n$ is thus a viable dark-matter candidate (scotino). Here we explore the phenomenology associated with the $SU(2)_R$ gauge group of this model, which allows it to appear at the TeV energy scale. The exciting possibility of $Z' \to 8$ charged leptons is discussed.Comment: 12 pages, 2 figure

The complex structure of HH 110 as revealed from Integral Field Spectroscopy

HH 110 is a rather peculiar Herbig-Haro object in Orion that originates due to the deflection of another jet (HH 270) by a dense molecular clump, instead of being directly ejected from a young stellar object. Here we present new results on the kinematics and physical conditions of HH 110 based on Integral Field Spectroscopy. The 3D spectral data cover the whole outflow extent (~4.5 arcmin, ~0.6 pc at a distance of 460 pc) in the spectral range 6500-7000 \AA. We built emission-line intensity maps of H$\alpha$, [NII] and [SII] and of their radial velocity channels. Furthermore, we analysed the spatial distribution of the excitation and electron density from [NII]/H$\alpha$, [SII]/H$\alpha$, and [SII] 6716/6731 integrated line-ratio maps, as well as their behaviour as a function of velocity, from line-ratio channel maps. Our results fully reproduce the morphology and kinematics obtained from previous imaging and long-slit data. In addition, the IFS data revealed, for the first time, the complex spatial distribution of the physical conditions (excitation and density) in the whole jet, and their behaviour as a function of the kinematics. The results here derived give further support to the more recent model simulations that involve deflection of a pulsed jet propagating in an inhomogeneous ambient medium. The IFS data give richer information than that provided by current model simulations or laboratory jet experiments. Hence, they could provide valuable clues to constrain the space parameters in future theoretical works.Comment: 12 pages, 15 figures Accepted in MNRA

Integral Field Spectroscopy of HH 262: The Spectral Atlas

HH 262 is a group of emitting knots displaying an "hour-glass" morphology in the Halpha and [SII] lines, located 3.5' to the northeast of the young stellar object L1551-IRS5, in Taurus. We present new results of the kinematics and physical conditions of HH 262 based on Integral Field Spectroscopy covering a field of 1.5'x3', which includes all the bright knots in HH 262. These data show complex kinematics and significant variations in physical conditions over the mapped region of HH 262 on a spatial scale of <3". A new result derived from the IFS data is the weakness of the [NII] emission (below detection limit in most of the mapped region of HH 262), including the brightest central knots. Our data reinforce the association of HH 262 with the redshifted lobe of the evolved molecular outflow L1551-IRS5. The interaction of this outflow with a younger one, powered by L1551 NE, around the position of HH 262 could give rise to the complex morphology and kinematics of HH 262.Comment: Accepted for publication in MNRA

The merging/AGN connection II. Ionization of the circumnuclear regions

We report the first results of a study of a sample of 20 galaxy mergers/interacting systems, using the VIMOS and PMAS integral field spectrographs. For each object, we extracted the integrated spectrum of the central regions and analyzed the ionization state using classical diagnostic diagrams (Veilleux & Osterbrock 1987). There is evidence of AGN ionization in 4 of the objects, i.e. 20% of the sample, a considerably higher fraction than found in previous studies ~4%Comment: 4 pages, 2 figures, accepted for publishing in A&A Letter

Efectividad de las modificaciones de estilo de vida sobre el control de la presión arterial en pacientes hipertensos

Introducción: Las modificaciones del estilo de vida han demostrado ser eficaces para el control de la presión arterial (PA). El objetivo de este trabajo es evaluar el efecto de la reducción del consumo de sal en la PA en hipertensos, conocer la calidad de la dieta y comprobar la adherencia a las recomendaciones dietéticas y de actividad física.Material y métodos: Estudio cuasiexperimental no controlado. Se seleccionaron aleatoriamente sujetos hipertensos a los que se realizó una entrevista estructurada para conocer sus hábitos de alimentación, consumo de sal y actividad física. Se determinaron las variables antropométricas y la PA. Se entregaron por escrito recomendaciones dietéticas y de actividad física. A los 30 días se reevaluaron.Resultados: 30 sujetos (17 mujeres y 13 varones), edad media 65,3±12,1 años. El 73,3% refería realizar dieta baja en sal. La calidad de la dieta mostró que la mayoría de los sujetos necesitaban cambios en su alimentación y eran sedentarios. Índice de masa corporal de 28,3±4,8 Kg/m2. PA sistólica de 139,1±18,9 mmHg y diastólica 81,8±10,1 mmHg.Segunda visita sin cambios en calidad de la dieta ni en actividad física aunque sí disminución en consumo de sal (p=0,028). PA sistólica media de 133,3±16,2 mmHg y diastólica 77,8±11,2 mmHg (p=0,04 en sistólica y  p=0,01 en diastólica).Conclusiones: La disminución del consumo de sal se asoció de forma estadísticamente significativa a una reducción de las cifras de PA. La calidad de la dieta de la muestra fue subóptima y la adherencia a las recomendaciones de estilo de vida baja
