Las denominaciones geográficas de calidad: un estudio comparativo entre Galicia y España

En España existen un gran número de productos en el sector agroalimentario que se acogen a las denominaciones geográficas de calidad. Estas figuras fueron inicialmente reconocidas en un ámbito nacional y posteriormente a nivel comunitario. El presente artículo revisa las distintas denominaciones geográficas de calidad que existen en la actualidad, en qué consisten y cuáles pueden encontrarse en España. Posteriormente analiza la aplicación en Galicia de estas denominaciones a los productos agrícolas y alimenticios, vinos y bebidas espirituosas y determina su representatividad, importancia económica y nivel de penetración en los mercados exteriores, realizando una comparación a nivel nacional.There are a lot of agricultural products and foodstuffs with geographical designations of quality. These figures were initially recognized in a national area and later at the Community level. In this article we check the different geographical designations that exist at present, what they consist on and which can be found in Spain. Later we study the geographical designations of Galician products applied to agricultural products and foodstuffs, wine-sector products and spirits drinks and we analyze their representation, economic importance and level of penetration in foreign markets, making a national comparison

The use of IRT to investigate the relationships between the g factor and cognitive tasks

Las relaciones entre el factor g y tareas de procesamiento de la información han abierto la puerta a la comprensión de la naturaleza de g ( Jensen, 1998). No obstante, es necesario superar determinados problemas metodológicos para poder comprender hasta qué punto las diferencias en g son ocasionadas por diferencias en procesos cognitivos. En este sentido, la falta de fiabilidad de las puntuaciones en las tareas de procesos puede llevar a conclusiones equivocadas sobre la naturaleza de dichas relaciones. Un medio de abordar este problema es seleccionar a las personas con un menor error de estimación del nivel de habilidad. Los resultados muestran un aumento de las correlaciones entre g y memoria de trabajo en el grupo de sujetos mejor medidos frente al grupo de personas con un error de estimación mayorMany authors have looked for the relations between the g factor and cognitive tasks in order to find out the nurture of the g factor (Jensen, 1998). Nevertheless, some methodological problems must be solved to understand if the individual differences in g are differences in cognitive processes. One of them is the low reliability of the scores in this kind of tasks. On the grounds of the standard error of the ability level estimation, we hypothesized that the correlations between the g factor and a working memory task would be larger in the g roup of the subjects better measured (less standard error). The results support this hypothesi

On the optimaL response of q-vortex

Wingtip vortices represent a hazard for the stability of the following airplane in airport highways. These flows have been usually modeled as swirling jets/wakes, which are known to be highly unstable and susceptible to breakdown at high Reynolds numbers for certain flow conditions, but different to the ones present in real flying airplanes. A very recent study based on Direct Numerical Simulations (DNS) shows that a large variety of helical responses can be excited and amplified when a harmonic inlet forcing is imposed. In this work, the optimal response of q-vortex (both axial vorticity and axial velocity can be modeled by a Gaussian profile) is studied by considering the time-harmonically forced problem with a certain frequency ω. We first reproduce Guo and Sun’s results for the Lamb-Oseen vortex (no axial flow) to validate our numerical code. In the axisymmetric case m = 0, the system response is the largest when the input frequency is null. The axial flow has a weak influence in the response for any axial velocity intensity. We also consider helical perturbations |m| = 1. These perturbations are excited through a resonance mechanism at moderate and large wavelengths as it is shown in Figure 1. In addition, Figure 2 shows that the frequency at which the optimal gain is obtained is not a continuous function of the axial wavenumber k. At smaller wavelengths, large response is excited by steady forcing. Regarding the axial flow, the unstable response is the largest when the axial velocity intensity, 1/q, is near to zero. For perturbations with higher azimuthal wavenumbers |m| > 1, the magnitudes of the response are smaller than those for helical modes. In order to establish an alternative validation, DNS has been carried out by using a pseudospectral Fourier formulation finding a very good agreement.Universidad de Málaga.

Arcillas cerámicas de Andalucía. VI. Yacimientos terciarios y cuaternarios de la provincia de Huelva. comarcas de Huelva y El Condado

Se estudian veintiséis muestras de arcilla de interés cerámico, procedentes de diversos yacimientos en explotación situados en el Sur de la provincia de Huelva, en las comarcas de El Condado y zona costera. Los materiales proceden de sedimentos terciarios (la mayor parte) y cuaternarios, constituidos por margas de textura arcillo-arenosa o arcillo-limosa y se emplean en la fabricación de ladrillos y tejas en fábricas modernas de gran producción. Los materiales más plásticos se utilizan en alfarería y talleres de cerámica artística en Huelva y Trigueros. Las técnicas empleadas han sido las Siguientes: Análisis químico, capacidad de cambio, análisis térmico ponderal y diferencial, diagramas de difracción de rayos X, examen al microscopio electrónico, análisis mecánico, agua de moldeo, plasticidad (Riecke) , poroSidad, secado a 50ºC. (Diagramas de Bourry) , contracción por calcinación, peso específico y resistencia a la compresión en probetas calcinadas. Se desprende que estas arcillas son de naturaleza fundamentalmente montmorillonítica, con una elevada participación de minerales caoliníticos y micáceos (ilita y micas potásicas). Como minerales secundarios y accesorios contienen cuarzo, geles y feldespatos. Todas las muestras contienen cantidades medias hasta altas de calcita en grano fino, que en ciertos casos es de mayor tamaño y puede llegar a ser perjudicial sin un tratamiento conveniente. Las pruebas tecnológicas indican que se trata de materiales naturales de buenas propiedades cerámicas, de utilidad para la industria de materiales de construcción, y en otros casos para alfarería y cerámica artística. La gran potencia de los yacimientos, su fácil explotación y laboreo, su situación en terreno llano y de buenas comunicaciones y la constancia en la composición química y textura de la materia bruta, hace que los consideremos de interés industrial.Twenty Six samples of clay, interesting from the ceramic viewpoint, from several beds located in the South of the province of Huelva, in the country of El Condado and the coast have been studied. The great majority of materials belong to the Tertiary and Quaternary sediments and are formed by marls of sandy or silty clayed texture. They are used by large modern factories producing bricks and tiles. The more plastic materials are used by pottery and artistic ceramic industries in Huelva and Trigueros. The following techniques have been used: Chemical analysis, base exchange capacity, ponderal thermal analysis, D. T. A., X-ray difraction, electronic microscope, mechanical analysis, moulding water, plasticity (Riecke), porosity, drying shrinkage at 50°C. (Bourry's diagrams) firing shrinkage, specific gravity and crushing strength of fired bodies. It is concluded that these clays are fundamentally of montmorillonitic nature, with, a high proportion of kaolinitic and micaceous minerals (illite and potasic micas). They contain as secondary minerals, quartz gels and feldspars. All the samples contain medium to high quantities of fine grain ed calcite, which, in some casos, may be of larger size, being pernicious without previous treatment. The technological tests suggest that these materials are of good ceramic properties, useful in the building industry and in other cases, for pottery and artistic ceramics. The great depth of these beds, their easy explotation and working, their situation on flat and well communicated land and the constancy of chemical and textural composition of the raw materials make them of industrial interest

On the effect of low blowing ratio continuous jets on wingtip vortex characteristics

Vortices are an unavoidable effect of flight, which appear behind the wing with a bounded length. The strength of these vortices, which are extremely stable, is due to the lift force [1]. That is the reason why this phenomenon is especially relevant during take-off and landing operations. In these situations, when aircraft are departing from or arriving to the airport runways, the following aircraft might feel two counter-rotating vortices which remain long time under normal environmental conditions. Unfortunately, this huge rotation of airflow patterns always destabilizes the following aircraft. Consequently, trailing vortices have a mighty influence on the air traffic control of airport runways, and they have justified the research interest in this topic since the 1960's [2]. However, aeronautical engineers are still searching for different technological strategies to breakdown these wingtip vortices.Short-Term Postdoctoral Stay of Talent Attraction Plan of Andalucía TECH ICE.

Arcillas cerámicas de Andalucía V. Yacimientos de terrenos ígneos y sedimentos primarios de la provincia de Huelva. Comarcas de Sierra Morena y Andévalo

Twenty two samples of clays, interesting from the ceramic viewpoint, from several beds located on the northern and central regions of the province of Huelva, in the country of Sierra Morena and El Andévalo, respectively, have he en studied. The materials belong to outcrops of igneous nature and slate sediments from the Silurian and Carboniferous, and are of highly sandy texture in general. They are used to make bricks and tiles. The materials of higher clay content are used in pottery and artistic ceramic industries, specially those from Aracena and Cortegana. The following techniques have been used: chemical arialysis, base exchange capacity, ponderal thermal analysis D.T.A., X-ray diffraction, electron microscopy, mechanical analysis, moulding water, plasticity (Riecke), porosity, drying shrinkage at 50ºC. (Bourry's diagrams), firing shrinkage, specific gravity and crushing strength in fired bodies. It is concluded that the main components of the materials belonging to the igneous outcrops (granites, porphides, etc.), are fundamentally of kaolinitic nature, with a high proportion of micaceous minerals, free quartz as an accesory mineral and a variable amount of hydrated iron and aluminum oxides. Minerals of 14 A spacings are scarce. Samples from altered slate of Andévalo show distinctly a higher illite content followed by kaolinite and iron and aluminum gels. The presence of montmorillonitic minerals is more obvious. The technological tests suggest) that these raw materials have good ceramic properties, with a high iron content, appropriate for the uses mentioned above. The small extension of these beds prevent the use of these materials by the large ceramic industries.Se estudian veintidós muestras de arcilla de interés cerámico procedentes de diversos yacimientos situados en las regiones norte y centro de la provincia de Huelva, en las comarcas de Sierra Morena y El Andévalo, respectivamente. Los materiales proceden de afloramientos de naturaleza ígnea y sedimentos de pizarras del Silúrico y Carbonífero, de textura fuertemente arenosa en general, y se emplean en la fabricación de ladrillos y tejas. Los materiales más arcillosos se utilizan en alfarerías y talleres de cerámica artística, destacando los de Aracena y Cortegana. Las técnicas empleadas han sido las siguientes: Análisis químico, capacidad de cambio, análisis térmico ponderal y diferencial, diagramas de difracción de rayos X, examen al microscopio electrónico, análisis mecánico, agua de moldeo, plasticidad (Riecke), porosidad, secado a 50ºC (diagramas de Bourry), contracción por calcinación, peso específico y resistencia a la compresión en probetas calcinadas. Se deduce que los materiales procedentes de yacimientos sobre afloramientos ígneos (granito, pórfidos, etc.) son de naturaleza fundamentalmente caolinita, con una alta proporción de minerales micáceos, cuarzo libre como mineral accesorio y un contenido variable en óxidos de hierro y aluminio hidratados. Minerales con espaciados de 14 A apenas son apreciables. Las muestras procedentes de pizarras alteradas de El Andévalo destacan por su mayor contenido en Hita, seguida de caolinita y geles de hierro y aluminio. Se intensifica la presencia de minerales montmorilloníticos. Las pruebas tecnológicas indican que se trata de materiales naturales de buenas propiedades cerámicas, con alto contenido en hierro, aptos para los usos que hemos citado

Transnational Dissemination of Discourses on Non-normative Sexualities through Netflix: the Sex Education Case (2019-2020)

This paper analyzes the series Sex Education’s role in the transnational dissemination of discourses on non-normative sexualities, equality and LGBTIQ+ diversity. From a LGBTIQ+ Studies perspective, a mixed design with non-experimental ex-post-facto methodology has been applied through transmedia measurement instruments and the ILGA World and Global Attitudes reports. Netflix –through Sex Education– is confirmed to transnationally spread values of diversity and LGBTIQ+ equality in countries without full social and legal protection for such diversity, promoting the construction of alternative subjectivities
