La imagen de Andalucía como destino turístico por parte de los países centroeuropeos

The image of a tourist destination is a key factor in the tourists' decision to choose a place to visit. This dissertation contains exploratory-descriptive research in which the image of the region of Andalusia as a tourist destination has been analysed. Through a review of the literature, general information has been collected on the concept of image along with its characteristics, followed by the review of other relevant elements that must be taken into account when it comes to the image of a tourist destination, such as the formation of the image or the factors associated with it. Besides, empirical research has been carried out, which includes a study of the image of the selected destination through a questionnaire aimed only at tourists who have previously visited the region and who come from Central European countries, consisting of a sample of 102 respondents.Universidad de Sevilla.

Assemblages and microthermometry of barite ore deposits from Chorriaca anticline, Neuquén Province

En este trabajo se estudió la mineralización de sulfatos de Ba presente en el anticlinal de Chorriaca. El mapeo de las distintas labores evidenció un fuerte control estratigráfico puesto que todos los depósitos se hallan hospedados en el miembro Agua de la Mula (Formación Agrio). La mineralogía se compone principalmente de baritina, calcita y óxidos de hierro. Los análisis texturales permitieron reconocer tres pulsos de mineralización, de los cuales el último habría sido el más importante. En cristales de baritina de este último se realizaron los estudios de inclusiones fluidas. Las inclusiones primarias más representativas se componen de agua con sales disueltas entre las cuales destacan algunas con cantidades subordinadas de hidrocarburos. Los resultados microtermométricos permitieron definir temperaturas de homogeneización superiores a los 300 °C y soluciones con bajas salinidades. Sobre la base de los resultados obtenidos se postula un origen hidrotermal para las manifestaciones del área estudiada.In this contribution, the barium sulfate mineralization from Chorriaca anticline was studied. All mines are hosted in carbonate layers (Agua de la Mula stratigraphical unit, Agrio Formation) that evidence a strong lithological control. The assemblages is mainly composed of barite, calcite and iron oxides. Their textures imply three mineralization events, from which the last one was the most important. Fluid inclusion studies on barite crystallized during this last event were carried out. The most representative primary fluid inclusions are composed of water with dissolved salts. Few of them also present hydrocarbons on the liquid phases. Microthermometry evidenced homogeneization temperatures above 300°C and solutions with low salinities. Regarding the reasons stated above we propose that this barite mineralization was generated by hydrothermal processes related to the magmatic activity of Neuquén basin.Fil: Leal, Pablo Rodrigo.

Experimental bone toolmaking: A proposal of technological analytical principles to knapped bones

Since the origins of technology, human groups have used a wide variety of lithic and organic raw materials to make tools. In particular, bone was used as raw material for creating knapped artefacts. Nevertheless, the recognition of these technological elements in the archaeological record has generated some debate, since modern taphonomy has shown that certain non-anthropic agents create modifications that can mimic knapped bone tools. For this reason, the criteria for identifying archaeological bone tools and pseudo-tools have still not been clearly defined. As a contribution to this subject, here we present the results of an experimental programme of intentional anthropic marrow fracturing of fresh and semi-fresh bovine long bones. After marrow removal, some of the diaphyseal fragments obtained were selected to be used directly as tools, while others were slightly retouched. The aim was to describe the bone toolmaking process and the simple and retouched tools obtained experimentally according to technological criteria. The technological analysis approach was based on an adaptation of the Logical Analytical System (LAS), which uses structural categories within an operative chain rather than techno-typological features. LAS has been widely used to analyse Pleistocene lithic assemblages and is here applied for the first time to the study of bone industry. The results allow us to present new analytical criteria with which to describe simple and retouched bone tools from a holistic perspective, combining technological and taphonomic terminology. Our intention is to improve the criteria for differentiating intentional retouching in bone tools from other modifications to bone remains generated by non-anthropic agents. The final goal of this study is to further the interdisciplinary study of minimally modified bone tools, proposing a technological method for studying knapped bone tools

Modulación de canales iónicos de relevancia terapéutica por la peimina, un análogo estructural de anestésicos locales

La peimina es un glucoalcaloide protonado a pH fisiológico (pKa = 9,5) utilizado comúnmente en la medicina tradicional china para aliviar síntomas gripales. El desconocimiento de los mecanismos por los que ejerce estas funciones la convierte en objeto de estudio de este trabajo, en el cual se ahonda en las posibles interacciones de la peimina, en el rango micromolar, con distintos canales iónicos de relevancia terapéutica como el receptor nicotínico de acetilcolina (nAChR), el canal de Cl- activado por Ca+2 (CaCC) y el canal de cloruro activado por voltaje ClC-0. Mediante la técnica de fijación de voltaje con dos microelectrodos en ovocitos de Xenopus, se pudo obtener que, a una concentración de 5 μM, la peimina: i) inhibe la corriente evocada por ACh (IACh), probablemente favoreciendo el estado desensibilizado del nAChR, dado que acelera la fase de desensibilización de la IACh y que el porcentaje de la IACh es mayor en la fase de meseta que en el pico de la corriente; ii) potencia la corriente evocada por CaCC (ICaCC), incluso a concentraciones submicromolares en algunas células y iii) inhibe la corriente evocada por ClC-0 (IClC-0) de una manera voltaje-dependiente, aumentando la inhibición con la hiperpolarización de la membrana. Es importante destacar que la peimina produce todos estos efectos a concentraciones inferiores a las requeridas por otros moduladores de estos canales iónicos

Assessment by laser-induced breakdown spectroscopy of penetration depth in limestones of four nano-biocides based on silver/titanium nanoparticles

[Abstract]: Four biocidal treatments based on nanoparticles were designed and their penetration depths were char- acterized by laser-induced breakdown spectroscopy (LIBS) technique. This kind of biocidal nanoparticles are being studied to be employed in historic buildings and stone monuments due to their capability to inhibit the growth of biofoulings. The effectiveness of the treatment is related to the penetration depth of the nanoparticles in the limestone pore. For this reason, LIBS depth profiling was used in this work to characterize the diffusion of the nanoparticles in the limestone matrix and to compare the penetration depth of the different treatments. Four different nano-biocides based on silver/titanium dioxide nanopar- ticles were analysed by LIBS in limestone from Novelda quarry (Alicante, Spain). This limestone has been widely employed in both historical and contemporary buildings in Spain. The positive detection of the emission line of Ag at 338.289 nm was examined in the depth-related emission spectra as evidence of the presence of the silver nanoparticles and derived nanocomposites in the limestone matrix. The LIBS depth-profiles that were generated, showed a decrease of the Ag net signal with depth due to the diffusion of the nanoparticles in the limestone. Furthermore, the comparison of the in-depth sequences of spectra, and of the Ag depth profiles evidenced penetration differences between the nano-biocides which were explained by differences in the hydrodynamic diameter of the nanoparti- cles that would affect their diffusion in the limestone pore. The results of this assessment demonstrate the capability and potential of LIBS technique for the in-depth characterization of the nanoparticles and for the comparison of the effectiveness of nanoparticles biocidal treatments based on their penetration in the stone matrix

Comparison of ALBAYZIN query-by-example spoken term detection 2012 and 2014 evaluations

Query-by-example spoken term detection (QbE STD) aims at retrieving data from a speech repository given an acoustic query containing the term of interest as input. Nowadays, it is receiving much interest due to the large volume of multimedia information. This paper presents the systems submitted to the ALBAYZIN QbE STD 2014 evaluation held as a part of the ALBAYZIN 2014 Evaluation campaign within the context of the IberSPEECH 2014 conference. This is the second QbE STD evaluation in Spanish, which allows us to evaluate the progress in this technology for this language. The evaluation consists in retrieving the speech files that contain the input queries, indicating the start and end times where the input queries were found, along with a score value that reflects the confidence given to the detection of the query. Evaluation is conducted on a Spanish spontaneous speech database containing a set of talks from workshops, which amount to about 7 h of speech. We present the database, the evaluation metric, the systems submitted to the evaluation, the results, and compare this second evaluation with the first ALBAYZIN QbE STD evaluation held in 2012. Four different research groups took part in the evaluations held in 2012 and 2014. In 2014, new multi-word and foreign queries were added to the single-word and in-language queries used in 2012. Systems submitted to the second evaluation are hybrid systems which integrate letter transcription- and template matching-based systems. Despite the significant improvement obtained by the systems submitted to this second evaluation compared to those of the first evaluation, results still show the difficulty of this task and indicate that there is still room for improvement.This research was funded by the Spanish Government ('SpeechTech4All Project' TEC2012 38939 C03 01 and 'CMC-V2 Project' TEC2012 37585 C02 01), the Galician Government through the research contract GRC2014/024 (Modalidade: Grupos de Referencia Competitiva 2014) and 'AtlantTIC Project' CN2012/160, and also by the Spanish Government and the European Regional Development Fund (ERDF) under project TACTICA
