Quasi-normal mode analysis in BEC acoustic black holes

We perform a quasi-normal mode analysis of black hole configurations in Bose-Einstein condensates (BEC). In this analysis we use the full Bogoliubov dispersion relation, not just the hydrodynamic or geometric approximation. We restrict our attention to one-dimensional flows in BEC with step-like discontinuities. For this case we show that in the hydrodynamic approximation quasi-normal modes do not exist. The full dispersion relation, however, allows the existence of quasi-normal modes. Remarkably, the spectrum of these modes is not discrete but continuous.Comment: 7 pages, 3 figure

Arte contemporáneo y participación: la reflexión y el diálogo como generadores de distracción positiva

So We could say that social relationships in hospital are very restrictive. They are always around illness. This article try to describe two different experiences taken place in Children Oncological room and Dialysis treatment room in Hospital Gregorio Marañon in Madrid. In both places we have projected Contemporary Art images on the walls. So with this action, we have tried to bring up participation and new dialogues in order to make possible other dialogues, and avoid illness item for a while to make people participate and socialize.The same action, projecting images, turns not only a temporary positive distraction but and education and relational chance.Both experiences have been a precedent for a bigger and more ambitious project which is to create a place where patients, companions and sanitary staff could share conversation, participate and socialize in order to disconnect from hospital and illness around cultural event. This is taken place at Patient Library in Hospital Universitario 12 de Octubre in Madrid.La realidad de la socialiación en el contexto hospitalario se ve muy restringida. La mayor parte de las relaciones giran en torno a la enfermedad. En este articulo se describen las experiencias llevadas a cabo en las habitaciones de oncología Infantil y la sala de tratamiento de diálisis en el Hospital Gregorio Marañón de Madrid. Proyectar imágenes sobre las paredes se presenta como una intervención que facilita la participación de quienes se encuentran ahí y genera dinámicas y diálogos que se traducen en otra forma de relacionarse más allá de la enfermedad. Dos contextos diferentes en los que una misma acción, proyectar, deriva no sólo en un momento de distracción, tambien en una oportunidad educativa y relacional. Ambas experiencias han servido como antecedente para inciar un proyecto más ambicioso, la creación de un espacio en el que pacientes, familiares y personal sanitario puedan ser dueños del espacio que ocupan a través de diferentes propuestas que desde el ámbito del arte contempóraneo les son ofrecidas en busca de su participación y colaboración, facilitando dispositivos que motiven la acción y la elección en un lugar, el hospital, en el que todo está programado. Ellos elegiran compartir, con el arte como excusa, momentos de desconexión y establecer diálogos en torno a su actividad. Este espacio es en la Biblioteca de Pacientes del Hospital Universitario 12 de Octubre de Madrid

Bioclimatology, structure, and conservation perspectives of Quercus pyrenaica, Acer opalus subsp. Granatensis, and Corylus avellana deciduous forests on Mediterranean bioclimate in the South-Central part of the Iberian Peninsula

The plant variability in the southern Iberian Peninsula consists of around 3500 different taxa due to its high bioclimatic, geographic, and geological diversity. The deciduous forests in the southern Iberian Peninsula are located in regions with topographies and specific bioclimatic conditions that allow for the survival of taxa that are typical of cooler and wetter bioclimatic regions and therefore represent the relict evidence of colder and more humid paleoclimatic conditions. The floristic composition of 421 samples of deciduous forests in the south-central part of the Iberian Peninsula were analyzed. The ecological importance index (IVI) was calculated, where the most important tree species were Quercuspyrenaica, Aceropalus subsp. Granatensis, and Corylusavellana. These species are uncommon in the south-central part of the Iberian Peninsula, forming forests of little extension. An analysis of the vertical distribution of the species (stratum) shows that the majority of the species of stratum 3 (hemicriptophics, camephytes, geophites, and nanophanerophytes) are characteristic of deciduous forests, and their presence is positively correlated with high values of bioclimatic variables related to humidity and presence of water in the soil (nemoral environments), while they are negatively correlated with high values of bioclimatic variables related to high temperatures, evapotranspiration, and aridity. This work demonstrates that several characteristic deciduous forest taxa are more vulnerable to disappearance due to the loss of their nemoral conditions caused by gaps in the tree or shrub canopy. These gaps lead to an increase in evapotranspiration, excess insolation, and a consequent loss of water and humidity in the microclimatic conditions.info:eu-repo/semantics/publishedVersio

Urgencias pediátricas atendidas en una consulta de atención primaria (II): estudio epidemiológico

ObjetivosAnalizar los motivos de consulta (MC), diagnósticos, tratamientos, pruebas complementarias (PC), resolución en atención primaria, derivaciones y antecedentes personales de las urgencias de una consulta de pediatría.DiseñoEstudio prospectivo, longitudinal, durante los días laborables de semanas alternas comprendidas entre el 1 de julio de 1996 y el 30 de junio de 1997.EmplazamientoConsulta de pediatría, urbana, del turno de tarde (14-21 horas), del Equipo de Atención Primaria (EAP) Vicente Soldevilla de Vallecas (Madrid).ParticipantesPoblación adscrita al EAP: 2.890 niños de 0-14 años.ResultadosSe atendieron 723 urgencias. Los principales MC fueron: fiebre (42,7%), síntomas catarrales (18,9%) y traumatismos (9,1%). Los diagnósticos más frecuentes fueron la amigdalitis/foco ORL (21,7%), el catarro de vías altas (CVA) (15,9%) y la gastroenteritis aguda (8,3%). En un 18,8% se realizó alguna PC (radiografías [44,9%] y urocultivos [43,4%]). Los tratamientos más frecuentes fueron los fármacos antitérmicos-analgésicos-antiinflamatorios (41,8%), antibióticos (19,7%), tolerancia oral y/o dietas (9,8%) y tratamiento traumatológico (5,2%). Se realizó tratamiento en el centro de salud en un 14,9%, siendo el 69,5% tratamientos traumatológicos. Se solucionó un 95,8% de las consultas. Las derivaciones más frecuentes (78,2%) se debieron a traumatismos.ConclusionesLa fiebre y los síntomas catarrales fueron los MC más frecuentes en menores de 10 años y los traumatismos en mayores de 10 años. La amigdalitis/foco ORL y el CVA fueron los diagnósticos más frecuentes en menores de 10 años y los traumatismos en mayores de 10 años. Las PC más solicitadas fueron las radiografías y los urocultivos. Los tratamientos más prescritos fueron fármacos antitérmicos-analgésicos-antiinflamatorios. En el centro de salud se realizaron fundamentalmente tratamientos traumatológicos. La atención primaria es un filtro eficaz de las urgencias hospitalarias. Los traumatismos fueron la principal causa de derivación al hospital.ObjectivesTo analyse the reasons for consultation (RC), diagnoses, treatments, further tests (FC), whether resolved at PC level, referrals and personal history, at a paediatrics emergency clinic.DesignA prospective, longitudinal study, during the working days of alternate weeks between July 1 1996 and June 30 1997.SettingUrban paediatrics clinic, on the afternoon shift (2 to 9 p.m.), of the Vicente Soldevilla Primary Care Team (PCT) in Vallecas (Madrid).ParticipantsPopulation registered with the PCT: 2890 children between 0 and 14.Results723 emergencies were attended. The main RC were: temperature (42.7%), catarrh (18.9%) and physical traumas (9.1%). The most common diagnoses were: tonsillitis/ ENT focus (21.7%), upper passage catarrh (UPC) (15.9%) and acute gastro-enteritis (8.3%). 18.8% had some further test (x-rays 44.9% and urine cultures 43.4%). The most common treatments were antithermic, analgesic and anti-inflammatory drugs (41.8%), antibiotics (19.7%), oral tolerance and/or diets (9.8%) and trauma treatment (5.2%). 14.9% were treated at the health centre, 69.5% of which were trauma treatments. 95.8% of the consultations were resolved. The most common referrals (78.2%) were due to trauma.ConclusionsTemperature and catarrh symptoms were the most common RC in children under 10, and trauma in children over 10. Tonsillitis/ENT focus and UPC were the most common diagnoses in the under-10s, and trauma in the over-10s. Most requested further tests were X-rays and urine cultures. Most commonly prescribed medicines were antithermic, analgesic and antiinflammatory drugs. Mainly trauma treatments were done at the health centre. Primary care is an effective filter of hospital emergencies. Traumas were the main cause of referrals to hospital

Socioeconomic Factors and the Consumption of Wine in Tenerife

In this paper we measure the impact of an individual's socioeconomic conditions on the decision to consume wine in a traditionally wine-producing area. Based on the data obtained in an exhaustive survey on wine consumption and through discrete choice models, we assess the changes which come about in the decisions to consume the different types of wine under consideration, and we obtain the most relevant distinctive and differentiated characteristics for each one of them.wine consumption, socioeconomic characteristics, discrete choice models, Food Consumption/Nutrition/Food Safety,
