    La percepción de la expresión facial en un contexto verbal facilita la activación del conocimiento conceptual a través del cual es interpretada. Con el objetivo de analizar cómo la emoción, a través del contexto verbal, modula la percepción de la expresión facial en sus niveles de valencia, activación y control, se realizó un primer experimento en el que se generó el contexto verbal mediante palabras de contenido emocional (positivo, negativo), antes del reconocimiento de una expresión mixta de alegría y tristeza. En un segundo experimento, manteniendo neutros tanto contexto verbal como expresión facial, se indujo un estado afectivo positivo o negativo, antes o después de la codificación del contexto verbal. En el primer experimento, la condición de contexto verbal positivo facilitó que la cara mixta de alegría se percibiera con una expresión de mayor seguridad/confianza (control) respecto a la cara mixta de tristeza. En el segundo experimento, la emoción positiva inducida de manera previa a la codificación del contexto verbal, generó que la cara se percibiera con una expresión de mayor activación, respecto a cuando la emoción fue negativa. Se discuten los resultados a partir del modelo constructivista de la emoción

    [Aims] We take advantage of the capability of the OTELO survey to obtain the H alpha luminosity function (LF) at z similar to 0.40. Because of the deepest coverage of OTELO, we are able to determine the faint end of the LF, and thus better constrain the star formation rate and the number of galaxies at low luminosities. The AGN contribution to this LF is estimated as well. [Methods] We make use of the multiwavelength catalogue of objects in the field compiled by the OTELO survey, which is unique in terms of minimum flux and equivalent width. We also take advantage of the pseudo-spectra built for each source, which allow the identification of emission lines and the discrimination of different types of objects. [Results] The H alpha luminosity function at z similar to 0.40 is obtained, which extends the current faint end by almost 1 dex, reaching minimal luminosities of log(10) L-lim = 38.5 erg s(-1) (or similar to 0.002 M-circle dot yr(-1)). The AGN contribution to the total H alpha luminosity is estimated. We find that no AGN should be expected below a luminosity of log(10) L = 38.6 erg s(-1). From the sample of non-AGN (presumably, pure SFG) at z similar to 0.40 we estimated a star formation rate density of rho(SFR) = 0.012 +/- 0.005 M-circle dot yr(-1) Mpc(-3).This work was supported by the Spanish Ministry of Economy and Competitiveness (MINECO) under the grants AYA2013- 46724- P, AYA2014 58861-C3-1- P, AYA2014-58861-C3-2-P, AYA2014-58861-C3-3- P, AYA2016 -75808-R, AYA2016-75931-C2-2-P, AYA2017-88007-C3-1-P, and AYA2017 -88007-C3-2- P.

    Objective: To determine yield and organoleptic characteristics from cheese made with positive milk to alcohol test. Design/methodology: Fresh milk was used from cows’ crosses of Brahman x American Brown Swiss, which were maintained in grazing. Eleven judges with semi-trained category were selected. The sensorial analysis was made using triangular, two of five, acceptance, flavor and texture profiles tests. In the taste and texture profiles, a ten-centimeter line was used to indicate intensity. Acceptance test was made with fifty untrained consumers. Data obtained were subjected to an analysis of variance, with the positive or negative response of milk to the alcohol test as the fixed effect; a difference between averages was determined by Tukey's test (P?0.05). Results: Cheese made with Positive Milk to Alcohol, presented less consumer acceptance (P?0.05), a higher intensity of hardness, porosity and a lower residual taste (P?0.05). Limitations on study/implications: Alcohol test is variable, so it is necessary to do the test daily to separate the milk. Finding/conclusion: Cheese made from positive milk to alcohol test has less consumer acceptance due to its organoleptic characteristics.Objetivo: Determinar el rendimiento y las características sensoriales de quesos frescos elaborados con leche Positiva a la Prueba del Alcohol. Diseño/metodología: Se utilizó leche fresca proveniente de vacas cruzas de Brahman x Suizo Pardo Americano, las cuales se mantuvieron en pastoreo. Se seleccionaron once jueces con categoría de semientrenados. En el análisis sensorial se utilizaron las pruebas, triangular, dos de cinco, de aceptación, perfil de textura y perfil de sabor. En los perfiles de sabor y textura se utilizó una línea de 10 cm para señalar la intensidad. La prueba de aceptación se realizó a 50 consumidores sin entrenamiento. Los datos obtenidos se sometieron a un análisis de varianza, el efecto fijo y la respuesta positiva o negativa de la leche a la prueba del alcohol; la diferencia entre promedios se determinó con la prueba de Tukey (P? 0.05). Resultados: Se observó que el queso elaborado con leche Positiva a la Prueba del Alcohol presenta una menor aceptación (P?0.05), mayor intensidad de dureza y porosidad y un menor sabor residual (P?0.05). Limitaciones del estudio/implicaciones: El resultado a la prueba del alcohol es variable, por lo que es necesario hacer la prueba diariamente para separar la leche. Hallazgo/conclusión: El queso elaborado con leche positiva a la prueba del alcohol tiene menor aceptación por el consumidor debido a sus características organolépticas

    Environmental and self-sufficiency assessment of the energy metabolism of tourist hubs on Mediterranean Islands : the case of Menorca (Spain)

    Get PDF
    SostenipraEnergy performance of island tourism has been analyzed in the literature. However, tourist services tend to concentrate in tourist hubs, especially where mass tourism predominates (e.g., Mediterranean), and the energy metabolism of these systems has not yet been assessed. The present paper models and estimates the energy metabolism of tourist hubs in the Menorca Island (Spain) by integrating social, geographical and environmental methods. Mobility (both external and internal) and consumption of lodging services were characterized through surveys to users (tourists) and business managers. An environmental assessment evaluated CO₂ emissions, and energy self-sufficiency potential was estimated via GIS data. The results indicate that, on average, a tourist consumes 4756 MJ with associated emissions of 277 kg of CO₂ per stay (20 days on average). Of all the energy flows, external mobility contributes the most to total emissions (77%). For every day spent in a tourist hub, a tourist consumes between 29 MJ and 93 MJ in lodging services, consumption that could be 100% satisfied by photovoltaic systems, and these systems would result in positive effects for the island. Sustainable tourism management might focus on promoting environmentally friendly transportation, energy efficient practices, and environmental communication through ecolabeling

    The Quaternary Active Faults Database of Iberia (QAFI v.2.0)

    Get PDF
    The Quaternary Active Faults Database of Iberia (QAFI) is an initiative lead by the Institute of Geology and Mines of Spain (IGME) for building a public repository of scientific data regarding faults having documented activity during the last 2.59 Ma (Quaternary). QAFI also addresses a need to transfer geologic knowledge to practitioners of seismic hazard and risk in Iberia by identifying and characterizing seismogenic fault-sources. QAFI is populated by the information freely provided by more than 40 Earth science researchers, storing to date a total of 262 records. In this article we describe the development and evolution of the database, as well as its internal architecture. Aditionally, a first global analysis of the data is provided with a special focus on length and slip-rate fault parameters. Finally, the database completeness and the internal consistency of the data are discussed. Even though QAFI v.2.0 is the most current resource for calculating fault-related seismic hazard in Iberia, the database is still incomplete and requires further review

    The miniJPAS survey quasar selection IV: Classification and redshift estimation with SQUEzE

    Full text link
    We present a list of quasar candidates including photometric redshift estimates from the miniJPAS Data Release constructed using SQUEzE. This work is based on machine-learning classification of photometric data of quasar candidates using SQUEzE. It has the advantage that its classification procedure can be explained to some extent, making it less of a `black box' when compared with other classifiers. Another key advantage is that using user-defined metrics means the user has more control over the classification. While SQUEzE was designed for spectroscopic data, here we adapt it for multi-band photometric data, i.e. we treat multiple narrow-band filters as very low-resolution spectra. We train our models using specialized mocks from Queiroz et al. (2022). We estimate our redshift precision using the normalized median absolute deviation, σNMAD\sigma_{\rm NMAD} applied to our test sample. Our test sample returns an f1f_1 score (effectively the purity and completeness) of 0.49 for quasars down to magnitude r=24.3r=24.3 with z2.1z\geq2.1 and 0.24 for quasars with z<2.1z<2.1. For high-z quasars, this goes up to 0.9 for r<21.0r<21.0. We present two catalogues of quasar candidates including redshift estimates: 301 from point-like sources and 1049 when also including extended sources. We discuss the impact of including extended sources in our predictions (they are not included in the mocks), as well as the impact of changing the noise model of the mocks. We also give an explanation of SQUEzE reasoning. Our estimates for the redshift precision using the test sample indicate a σNMAD=0.92%\sigma_{NMAD}=0.92\% for the entire sample, reduced to 0.81\% for r<22.5r<22.5 and 0.74\% for r<21.3r<21.3. Spectroscopic follow-up of the candidates is required in order to confirm the validity of our findings.Comment: Accepted in A&A 24 pages, 24 figures, 7 table

    Borrelia burgdorferi infection induces long-term memory-like responses in macrophages with tissue-wide consequences in the heart

    Lyme carditis is an extracutaneous manifestation of Lyme disease characterized by episodes of atrioventricular block of varying degrees and additional, less reported cardiomyopathies. The molecular changes associated with the response to Borrelia burgdorferi over the course of infection are poorly understood. Here, we identify broad transcriptomic and proteomic changes in the heart during infection that reveal a profound down-regulation of mitochondrial components. We also describe the long-term functional modulation of macrophages exposed to live bacteria, characterized by an augmented glycolytic output, increased spirochetal binding and internalization, and reduced inflammatory responses. In vitro, glycolysis inhibition reduces the production of tumor necrosis factor (TNF) by memory macrophages, whereas in vivo, it produces the reversion of the memory phenotype, the recovery of tissue mitochondrial components, and decreased inflammation and spirochetal burdens. These results show that B. burgdorferi induces long-term, memory-like responses in macrophages with tissue-wide consequences that are amenable to be manipulated in vivo.Supported by grants from the Spanish Ministry of Science, Innovation and Universities (MCIU) co-financed with FEDER funds (SAF2015-65327-R and RTI2018-096494-B-100 to JA; BFU2016-76872-R to EB, AGL2017-86757-R to LA, SAF2017-87301-R to MLMC, SAF2015-64111-R to AP, SAF2015-73549-JIN to HR), Instituto de Salud Carlos III (PIE13/0004 to AP), the Basque Government Department of Health (2015111117 to LA), the Basque Foundation for Innovation and Health Research (BIOEF), through the EiTB Maratoia grant BIO15/CA/016/BS to MLMC, the regional Government of Andalusia co-funded by CEC and FEDER funds (Proyectos de Excelencia P12-CTS-2232) and Fundación Domingo Martínez (to AP).

    Pancreatic metastases from renal cell carcinoma. Postoperative outcome after surgical treatment in a Spanish multicenter study (PANMEKID)

    Get PDF
    Background: Renal Cell Carcinoma (RCC) occasionally spreads to the pancreas. The purpose of our study is to evaluate the short and long-term results of a multicenter series in order to determine the effect of surgical treatment on the prognosis of these patients. Methods: Multicenter retrospective study of patients undergoing surgery for RCC pancreatic metastases, from January 2010 to May 2020. Variables related to the primary tumor, demographics, clinical characteristics of metastasis, location in the pancreas, type of pancreatic resection performed and data on short and long-term evolution after pancreatic resection were collected. Results: The study included 116 patients. The mean time between nephrectomy and pancreatic metastases' resection was 87.35 months (ICR: 1.51-332.55). Distal pancreatectomy was the most performed technique employed (50 %). Postoperative morbidity was observed in 60.9 % of cases (Clavien-Dindo greater than IIIa in 14 %). The median follow-up time was 43 months (13-78). Overall survival (OS) rates at 1, 3, and 5 years were 96 %, 88 %, and 83 %, respectively. The disease-free survival (DFS) rate at 1, 3, and 5 years was 73 %, 49 %, and 35 %, respectively. Significant prognostic factors of relapse were a disease free interval of less than 10 years (2.05 [1.13-3.72], p 0.02) and a history of previous extrapancreatic metastasis (2.44 [1.22-4.86], p 0.01). Conclusions: Pancreatic resection if metastatic RCC is found in the pancreas is warranted to achieve higher overall survival and disease-free survival, even if extrapancreatic metastases were previously removed. The existence of intrapancreatic multifocal compromise does not always warrant the performance of a total pancreatectomy in order to improve survival. (C) 2021 The Authors. Published by Elsevier Ltd
