Variaciones del drama historial en Lope de Vega
2013
A partir de la exposición de los fundamentos que subyacen a la investigación presentada, y que la vinculan a otras anteriores, y en los que se aborda el concepto y las características del drama historial en Lope de Vega, el ensayo se centra en la distinción de dos modos fundamentales del drama historial: la conmemoración de hechos históricos famosos, por un lado, y el análisis del conflicto moral, casi siempre de índole privada, que estalla en circunstancias históricas concretas, por el otro. Estas dos grandes estrategias de significación, la propia de la construcción de una memoria colectiva, asociada a la de la identidad de la naciente nación, y la propia de la exploración de la identidad…
Gene-diet interaction in plasma lipid response to plant sterols and stanols: A review of clinical trials
2021
Abstract Plant sterols and stanols (PS) are well known for their cholesterol-lowering effect by reducing intestinal absorption of cholesterol. However, genetic factors modulate the low-density lipoprotein cholesterol (LDL-C) response to PS therapy. This review examines clinical trials evaluating the impact of the main genes associated with response of plasma lipid concentrations to PS intake: APOE, CYP7A1, ABCG5/G8, NPC1L1, CETP, APOA4/A5, SCARBI, HMGCR, PPARα, LIPC, MTHFR and LPA. Evidence indicates that carriers of mutant allele of the CYP7A1 c. −204 A > C variant experience a greater plasma cholesterol reduction after PS intake, although there is discrepancy for the rest of genetic varia…
Towards a poïetic of are or the stakes of a new interpretation of the being : the possibilities and the limits of the renewal of the Metaphysics from…
2012
The “being” remains still and always today an extremely mysterious and polemic object for the philosophers as for the individual who we are. Face to the perpetual reappearance of this object in the form of a fundamental interrogation, the question is to know if we are confronted to an insoluble problem for the reason or if it is a methodological problem which it is advisable to raise. Beyond of a new attempt at destruction of Metaphysics in all its forms and its dimensions by the postmoderns, we must try to reflect today on the true positivity of the questioning of the “being”. From Kant to Bachelard, we are seeing a gradual opening during the history through the way of another practice whi…
The impact of theatrical experiences on young adults in Spain
2018
This study examines how young adults experience theatre and how this activity impacts their personal development. A total of 305 subjects, between 14 and 29 years old, completed the 'Theatre and me' (T&Y) battery of questions. Correlation and variance analysis were conducted considering age and gender. Older subjects reported that participating in drama activities has a greater impact on their lives, helps them to have a greater proclivity to take risks and to be more open-minded. With respect to gender, girls score higher than boys in 'Tolerance to RiskTaking and Commitment', 'Identity and Consciousness', Expression of Feeling' and 'Escape'
Great Minds Think Alike? Spatial Search Processes Can Be More Idiosyncratic When Guided by More Accurate Information.
2022
Existing research demonstrates that pre-decisional information sampling strategies are often stablewithin a given person while varying greatly across people. However, it remains largely unknown whatdrives these individual differences, that is, why in some circumstances we collect information moreidiosyncratically. In this brief report, we present a pre-registered online study of spatial search. Usinga novel technique that combines machine-learning dimension reduction and sequence alignment algo-rithms, we quantify the extent to which the shape and temporal properties of a search trajectory areidiosyncratic. We show that this metric increases (trajectories become more idiosyncratic) when a p…
Oxygen depletion in dense molecular clouds: a clue to a low O2 abundance?
2011
Context: Dark cloud chemical models usually predict large amounts of O2, often above observational limits. Aims: We investigate the reason for this discrepancy from a theoretical point of view, inspired by the studies of Jenkins and Whittet on oxygen depletion. Methods: We use the gas-grain code Nautilus with an up-to-date gas-phase network to study the sensitivity of the molecular oxygen abundance to the oxygen elemental abundance. We use the rate coefficient for the reaction O + OH at 10 K recommended by the KIDA (KInetic Database for Astrochemistry) experts. Results: The updates of rate coefficients and branching ratios of the reactions of our gas-phase chemical network, especially N + C…
The hyperfine structure in the rotational spectrum of CF+
2012
Context. CF+ has recently been detected in the Horsehead and Orion Bar photo-dissociation regions. The J=1-0 line in the Horsehead is double-peaked in contrast to other millimeter lines. The origin of this double-peak profile may be kinematic or spectroscopic. Aims. We investigate the effect of hyperfine interactions due to the fluorine nucleus in CF+ on the rotational transitions. Methods. We compute the fluorine spin rotation constant of CF+ using high-level quantum chemical methods and determine the relative positions and intensities of each hyperfine component. This information is used to fit the theoretical hyperfine components to the observed CF+ line profiles, thereby employing the h…
EVIDENCE OF NON-THERMAL X-RAY EMISSION FROM HH 80
2013
Protostellar jets appear at all stages of star formation when the accretion process is still at work. Jets travel at velocities of hundreds of km s -1, creating strong shocks when interacting with the interstellar medium. Several cases of jets have been detected in X-rays, typically showing soft emission. For the first time, we report evidence of hard X-ray emission possibly related to non-thermal processes not explained by previous models of the post-shock emission predicted in the jet/ambient interaction scenario. HH 80 is located at the south head of the jet associated with the massive protostar IRAS 18162-2048. It shows soft and hard X-ray emission in regions that are spatially separate…
X-ray emission from stellar jets by collision against high-density molecular clouds: an application to HH 248
2015
We investigate the plausibility of detecting X-ray emission from a stellar jet that impacts against a dense molecular cloud. This scenario may be usual for classical T Tauri stars with jets in dense star-forming complexes. We first model the impact of a jet against a dense cloud by 2D axisymmetric hydrodynamic simulations, exploring different configurations of the ambient environment. Then, we compare our results with XMM-Newton observations of the Herbig-Haro object HH 248, where extended X-ray emission aligned with the optical knots is detected at the edge of the nearby IC 434 cloud. Our simulations show that a jet can produce plasma with temperatures up to 10 MK, consistent with producti…
CONSTRAINTS ON THE PROGENITOR SYSTEM AND THE ENVIRONS OF SN 2014J FROM DEEP RADIO OBSERVATIONS
2014
We report deep EVN and eMERLIN observations of the Type Ia SN 2014J in the nearby galaxy M 82. Our observations represent, together with JVLA observations of SNe 2011fe and 2014J, the most sensitive radio studies of Type Ia SNe ever. By combining data and a proper modeling of the radio emission, we constrain the mass-loss rate from the progenitor system of SN 2014J to $\dot{M} \lesssim 7.0\times 10^{-10}\, {\rm M_{\odot}\, yr^{-1}}$ (3-$\sigma$; for a wind speed of $100\, {\rm km s^{-1}}$). If the medium around the supernova is uniform, then $n_{\rm ISM} \lesssim 1.3 {\rm cm^3}$ (3-$\sigma$), which is the most stringent limit for the (uniform) density around a Type Ia SN. Our deep upper lim…
