Optical photometry of the UCM Lists I and II

We present Johnson B CCD photometry for the whole sample of galaxies of the Universidad Complutense de Madrid (UCM) Survey Lists I and II. They constitute a well-defined and complete sample of galaxies in the Local Universe with active star formation. The data refer to 191 S0 to Irr galaxies at an averaged redshift of 0.027, and complement the already published Gunn r, J and K photometries. In this paper the observational and reduction features are discussed in detail, and the new colour information is combined to search for clues on the properties of the galaxies, mainly by comparing our sample with other surveys.Comment: 14 pages, 7 PostScript figures, accepted for publication in A&AS, also available vi ftp at ftp://cutrex.fis.ucm.es/pub/OUT/pag/PAPERS

Generated emotions by various types of games in physical education

El objetivo del presente estudio ha sido ahondar en el conocimiento de las emociones generadas a través de la práctica de diversos tipos de juegos, mediante la puesta en práctica de una propuesta diseñada a tal efecto. Más concretamente se ha tratado de conocer en qué medida, los juegos cooperativos y de oposición permiten el desarrollo emocional del alumnado en comparación con los juegos populares cooperativos y de oposición. Los participantes han sido un total de 50 alumnos y alumnas de sexto curso de Educación Primaria. El instrumento empleado ha sido el cuestionario sobre las percepciones socioemocionales de Gil-Madrona y Martínez (2016). Los resultados indican una gran similitud entre la utilización de los juegos cooperativos y juegos populares cooperativos. No obstante, los juegos populares de oposición producen mayores emociones positivas en el alumnado respecto a los juegos de oposición. El porcentaje de alumnado que se decanta por las emociones plancenteras es manifiestamente superior al de aquellos que se decantan por las displacenteras. Finalmente, se concluye que la propuesta utilizada es eficaz para producir emociones en los cuatro dominios de acción motriz objeto de estudioThe aim of this research has been to know which are the generated emotions through the practice of diverse kinds of games, through a proposal. Specifically, it is have been tried to know how cooperative and opposition games allow for the emotional development of the students with respect to traditional cooperative games and traditional opposition games. A total of 50 children of 6th grade took part in this work. The instrument used was the Gil-Madrona and Martinez's questionnaire (2016) about socio-emotional perceptions. The results indicate a similarity between using cooperative and traditional cooperative games. However, traditional opposition games produce greater positive emotions in students with respect to opposition games. Finally, it is concluded that the approach used is effective to produce emotions in the four motor domains studie

Optical photometry of the UCM Lists I and II. II-B band surface photometry and morphological discussion

We present Johnson B surface photometry for the UCM Survey galaxies. One-dimensional bulge-disk decomposition is attempted, discussing on fitting functions and computational procedures. The results from this decomposition, jointly with concentration indices and an asymmetry coefficient, are employed to study the morphological properties of these galaxies. We also compare our results with the previous morphological classification established using Gunn r imaging data and with other samples of galaxies. No major statistical differences in morphology are found between red and blue data, although some characteristics such as size and luminosity concentration vary. We find a correlation between luminosity and size. Several parameters are used to segregate the objects according to their morphological type.Comment: 19 pages, 20 PostScript figures, accepted for publication in A&A, also available via anonymous ftp at ftp://cutrex.fis.ucm.es/pub/OUT/pag/PAPERS/AA0

The use of pocket-size imaging devices: a position statement of the European Association of Echocardiography.

Pocket-size imaging devices are a completely new type of echo machines which have recently reached the market. They are very cheap, smartphone-size hand-held echo machines with limited technical capabilities. The aim of this European Association of Echocardiography (EAE) position paper is to provide recommendations on the use of pocket-size imaging devices in the clinical arena by profiling the educational needs of potential users other than cardiologists experts in echo. EAE recommendations about pocket-size imaging devices can be summarized in: (1) pocket-size imaging devices do not provide a complete diagnostic echocardiographic examination. The range of indications for their use is therefore limited. (2) Imaging assessment with pocket-size imaging devices should be reported as part of the physical examination of the patient. Image data should be stored according to the applicable national rules for technical examinations. (3) With the exception of cardiologists who are certified for transthoracic echocardiography according to national legislation, specific training and certification is recommended for all users. The certification should be limited to the clinical questions that can potentially be answered by pocket-size devices. (4) The patient has to be informed that an examination with the current generation of pocket-size imaging devices does not replace a complete echocardiogram.Peer reviewe

Inadequate heart rate control despite widespread use of beta-blockers in outpatients with stable CAD: findings from the international prospective CLARIFY registry

Background: To use CLARIFY, a prospective registry of patients with stable CAD (45 countries), to explore heart rate (HR) control and beta-blocker use.<p></p> Methods: We analyzed the CLARIFY population according to beta-blocker use via descriptive statistics with Pearson's χ2 test for comparisons, as well as a multivariable stepwise model.<p></p> Results: Data on beta-blocker use was available for 32,914 patients, in whom HR was 68 ± 11 bpm; patients with angina, previous myocardial infarction, and heart failure had HRs of 69 ± 12, 68 ± 11, and 70 ± 12 bpm, respectively. 75% of these patients were receiving beta-blockers. Bisoprolol (34%), metoprolol tartrate (16%) or succinate (13%), atenolol (15%), and carvedilol (12%) were mostly used; mean dosages were 49%, 76%, 35%, 53%, and 45% of maximum doses, respectively. Patients aged < 65 years were more likely to receive beta-blockers than patients ≥ 75 years (P < 0.0001). Gender had no effect. Subjects with HR ≤ 60 bpm were more likely to be on beta-blockers than patients with HR ≥ 70 bpm (P < 0.0001). Patients with angina, previous myocardial infarction, heart failure, and hypertension were more frequently receiving beta-blockers (all P < 0.0001), and those with PAD and asthma/COPD less frequently (both P < 0.0001). Beta-blocker use varied according to geographical region (from 87% to 67%).<p></p> Conclusions: Three-quarters of patients with stable CAD receive beta-blockers. Even so, HR is insufficiently controlled in many patients, despite recent guidelines for the management of CAD. There is still much room for improvement in HR control in the management of stable CAD

Quantum anomaly and 2D-3D crossover in strongly interacting Fermi gases

We present an experimental investigation of collective oscillations in harmonically trapped Fermi gases through the crossover from two to three dimensions. Specifically, we measure the frequency of the radial monopole or breathing mode as a function of dimensionality in Fermi gases with tunable interactions. The frequency of this mode is set by the adiabatic compressibility and probes the thermodynamic equation of state. In 2D, a dynamical scaling symmetry for atoms interacting via a {\delta}-potential predicts the breathing mode to occur at exactly twice the harmonic confinement frequency. However, a renormalized quantum treatment introduces a new length scale which breaks this classical scale invariance resulting in a so-called quantum anomaly. Our measurements deep in the 2D regime lie above the scale-invariant prediction for a range of interaction strengths indicating the breakdown of a {\delta}-potential model for atomic interactions. As the dimensionality is tuned from 2D to 3D we see the breathing oscillation frequency evolve smoothly towards the 3D limit.Comment: 5 pages, 3 figure
