    La prescripción del ejercicio físico para personas mayores: valores normativos de la condición física

    Full text link
    La evaluación de la condición física debe ser considerado como un aspecto a tener en cuenta a la hora de determinar la capacidad funcional de los ancianos. Debido a la no existía de unos valores referenciales, a partir de los cuales determinar el estado físico de los ancianos, y a las posibilidades que esta información nos daría, a la hora de prescribir ejercicio, fue lo que nos condujo a la llevar a cabo este estudio. El estudio etnográfico se llevó a cabo en la Comunidad Autónoma Gallega y en el se testaron a 159 hombres y 692 mujeres, todos mayores de 65 años e inscriptos en programas de actividad física. La muestra realizó voluntariamente las ocho pruebas de que consta la Batería E.C.F.A, mediante la cual se evaluó: 1)Composición corporal, 2)Fuerza máxima de prensión manual, 3)Equilibrio monopodal, 4)Fuerza resistencia abdominal, 5)Flexibilidad anterior del tronco, 6)Fuerza máxima de piernas, 7)Coordinación Oculo-manual (Agilidad manual) y 8)Resistencia Cardio-respiratoria (Caminar 2 Km)

    An H2CO 6cm Maser Pinpointing a Possible Circumstellar Torus in IRAS18566+0408

    We report observations of 6cm, 3.6cm, 1.3cm, and 7mm radio continuum, conducted with the Very Large Array towards IRAS18566+0408, one of the few sources known to harbor H2CO 6cm maser emission. Our observations reveal that the emission is dominated by an ionized jet at cm wavelengths. Spitzer/IRAC images from GLIMPSE support this interpretation, given the presence of 4.5um excess emission at approximately the same orientation as the cm continuum. The 7mm emission is dominated by thermal dust from a flattened structure almost perpendicular to the ionized jet, thus, the 7mm emission appears to trace a torus associated with a young massive stellar object. The H2CO 6cm maser is coincident with the center of the torus-like structure. Our observations rule out radiative pumping via radio continuum as the excitation mechanism for the H2CO 6cm maser in IRAS18566+0408.Comment: 20 pages, 4 figures, ApJ (in press

    Mid-Infrared Photometry and Spectra of Three High Mass Protostellar Candidates at IRAS 18151-1208 and IRAS 20343+4129

    We present arcsecond-scale mid-ir photometry (in the 10.5 micron N band and at 24.8 microns), and low resolution spectra in the N band (R~100) of a candidate high mass protostellar object (HMPO) in IRAS 18151-1208 and of two HMPO candidates in IRAS 20343+4129, IRS 1 and IRS 3. In addition we present high resolution mid-ir spectra (R~80000) of the two HMPO candidates in IRAS 20343+4129. These data are fitted with simple models to estimate the masses of gas and dust associated with the mid-ir emitting clumps, the column densities of overlying absorbing dust and gas, the luminosities of the HMPO candidates, and the likely spectral type of the HMPO candidate for which [Ne II] 12.8 micron emission was detected (IRAS 20343+4129 IRS 3). We suggest that IRAS 18151-1208 is a pre-ultracompact HII region HMPO, IRAS 20343+4129 IRS 1 is an embedded young stellar object with the luminosity of a B3 star, and IRAS 20343+4129 IRS 3 is a B2 ZAMS star that has formed an ultracompact HII region and disrupted its natal envelope.Comment: 40 pages, 8 figures, 3 tables.

    A road to nowhere? The non-transitional sequence at El Esquilleu (Cantabria, Spain)

    Full text link
    El Esquilleu cave has one of the most complete Middle Paleolithic stratigraphies of northern Iberia with a complete chronological framework almost continuous from the beginning of MIS3. The complete analysis of the materials including the last section of the sequence corresponding to the last chronological interval of the occupation in the region shows clear evolutionary tendencies by important changes in the composition of the lithic assemblage. Its study confirms a continuous occupation without any gaps during the Mousterian until recent dates but without any Upper Paleolithic presence. This sequence, referenced to the Mousterian settlement of the Picos de Europa mountains, testifies to the existence of a Mousterian presence in northern Iberia with no clear relation to other Cantabrian areas. Consequently, its occupation without a break until the crucial phase of the end of the Middle Paleolithic suggests a non-transitional process in the history of local Neanderthal groups

    The high velocity outflow in NGC6334I

    Get PDF
    We observed the high velocity outflow originating from NGC6334I in several CO transitions with the APEX telescope, with the goal of deriving the physical parameters of the gas. Using an LVG analysis, we studied line ratios between the CO(3-2), CO(4-3), and CO(7-6) data as a function of the density and of the kinetic temperature of the gas. An upper limit on the CO column density is derived by comparison with 13CO data. We constrained the temperature to be higher than 50 K and the H_2 density to values higher than n~10^4 cm^{-3} towards the peak position in the red lobe, while T>15 K and n>10^3 cm^{-3} are derived towards the peak position in the blue lobe. The physical parameters of the outflow, its mass and its energetics, have been computed using the temperatures derived from this analysis. We conclude that high kinetic temperatures are present in the outflow and traced by high excitation CO lines. Observations of high-J CO lines are thus needed to infer reliable values of the kinetic temperatures and of the other physical parameters in outflows.Comment: APEX A&A special issue, accepte

    Comparative study of complex N- and O-bearing molecules in hot molecular cores

    Full text link
    We have observed several emission lines of two Nitrogen-bearing (C2H5CN and C2H3CN) and two Oxygen-bearing (CH3OCH3 and HCOOCH3) molecules towards a sample of well-known hot molecular cores (HMCs) in order to check whether the chemical differentiation seen in the Orion-HMC and W3(H_2O) between O- and N-bearing molecules is a general property of HMCs. With the IRAM-30m telescope we have observed 12 HMCs in 21 bands, centered at frequencies from 86250 to 258280 MHz. The rotational temperatures obtained range from ~100 to ~150 K in these HMCs. Single Gaussian fits performed to unblended lines show a marginal difference in the line peak velocities of the C2H5CN and CH3OCH3 lines, indicating a possible spatial separation between the region traced by the two molecules. On the other hand, neither the linewidths nor the rotational temperatures and column densities confirm such a result. By comparing the abundance ratio of the pair C2H5CN/C2H3CN with the predictions of theoretical models, we derive that the age of our cores ranges between 3.7 and 5.9x10^{4} yrs. The abundances of C2H5CN and C2H3CN are strongly correlated, as expected from theory which predicts that C2H3CN is formed through gas phase reactions involving C2H5CN. A correlation is also found between the abundances of C2H3CN and CH3OCH3, and C2H5CN and CH3OCH3. In all tracers the fractional abundances increase with the H_2 column density while they are not correlated with the gas temperature.Comment: Accepted for publication in A&A, 56 page

    Dense gas in IRAS 20343+4129: an ultracompact HII region caught in the act of creating a cavity

    Get PDF
    The intermediate- to high-mass star-forming region IRAS 20343+4129 is an excellent laboratory to study the influence of high- and intermediate-mass young stellar objects on nearby starless dense cores, and investigate for possible implications in the clustered star formation process. We present 3 mm observations of continuum and rotational transitions of several molecular species (C2H, c-C3H2, N2H+, NH2D) obtained with the Combined Array for Research in Millimetre-wave Astronomy, as well as 1.3 cm continuum and NH3 observations carried out with the Very Large Array, to reveal the properties of the dense gas. We confirm undoubtedly previous claims of an expanding cavity created by an ultracompact HII region associated with a young B2 zero-age main sequence (ZAMS) star. The dense gas surrounding the cavity is distributed in a filament that seems squeezed in between the cavity and a collimated outflow associated with an intermediate-mass protostar. We have identified 5 millimeter continuum condensations in the filament. All of them show column densities consistent with potentially being the birthplace of intermediate- to high-mass objects. These cores appear different from those observed in low-mass clustered environments in sereval observational aspects (kinematics, temperature, chemical gradients), indicating a strong influence of the most massive and evolved members of the protocluster. We suggest a possible scenario in which the B2 ZAMS star driving the cavity has compressed the surrounding gas, perturbed its properties and induced the star formation in its immediate surroundings.Comment: 17 pages, 13 figures.
