Influence of OH- concentration on the illitization of kaolinite at high pressure

The products of hydrothermal reactions of kaolinite at 300°C and 1000 bars were studied in KOH solutions covering an OH- concentration, [OH-], of 1M to 3.5M. XRD patterns indicated a notable influence of the [OH-] on the reaction. At [OH]≥3M, the only stable phase was muscovite/illite. The content of muscovite/illite was calculated from the analysis of the diagnostic 060 reflections of kaolinite and muscovite/illite. The results showed a linear dependence of kaolinite and muscovite/illite contents with [OH-]. 27Al MAS NMR spectroscopy revealed the formation of small nuclei of K-F zeolite at high [OH-]. Finally, modelling of the 29Si MAS NMR spectra indicated that the Si/Al ratio of the muscovite/illite formed was very close to that of muscovite, at least in the mineral formed at low [OH-]. In good agreement with the XRD data, the quantification of the reaction products by 29Si MAS NMR indicated a linear decrease of the kaolinite content with increasing OH- concentration.Dirección General de Investigación Científica y Técnica CTQ2007-63297Junta de Andalucía P06-FQM-0217

Android app for automatic music composition

In this contribution, we present an Android App that generates music automatically replicating a specific contemporary genre, specifically rock music. The composition system is based on the analysis of a set of songs of the desired genre. The analysis results the automatic composition algorithm requires are exported to a JSON file that can be readily imported and parsed. The Android App developed creates a symbolic representation of the music generated for drums, bass and rhythm guitar that can be exported to a MIDI file or audio waveform. The evaluation results show that the automatic compositions generated are not distinguished amongst other excerpts created by human composers.Universidad de Málaga.

La gestión de la asistencia religiosa a los emigrantes españoles durante el franquismo

This article purpose is to delve into the Spanish Church and Franco’s Regimen relationship regarding the so-called “economic migration” during the sixties and seventies. In 1952, the Holy See dictated the regulations that should applied to the emigrant’s religious assistance. Albeit it was up to the different National Churches setting into motion all the process through the chaplains’ presence and the missions’ erection in the host countries. Concerning the Spanish example, the Church benefited from the Dictatorship support when it came to develop its mission between the Spanish abroad. This cooperation took shape legally, confirming the important role the Church had to play in the emigrant context. But it also meant an economic contribution, and a common speech, addressed to the emigrants, based on the National Catholicism premises.Este artículo tiene como objetivo profundizar en la colaboración establecida entre la Iglesia española y el franquismo en el ámbito de la denominada «emigración económica» de los años sesenta y setenta. En 1952 la Santa Sede dictó la normativa que debía reglar la asistencia religiosa a los emigrantes, sin embargo, fueron las Iglesias nacionales quienes llevaron a la práctica el procedimiento a través del envío de capellanes de emigrantes y la erección de misiones católicas en los países de acogida. En el caso español, la Iglesia contó con el apoyo de la dictadura a la hora de desarrollar su acción entre los españoles en el extranjero, hecho que quedó materializado en las disposiciones legales que ratificaban la importancia del papel de la Iglesia en el contexto migratorio, en la financiación de su actuación y en el discurso común puesto en circulación entre los emigrantes basado en las premisas del nacionalcatolicismo

Los límites entre el horror y lo siniestro en la representación de la violencia en Colombia

This article explores the boundary between horror and uncanny based on the essay Das Unheimliche, published by Sigmund Freud in 1919. The analysis is developed through certain images linked to the armed conflict in Colombia, produced by the artists Juan Manuel Echavarría and Juan David Ortiz, and the photojournalist Jesús Abad Colorado. The notions of reality and fiction, as well as the complex dilemmas relating to the aestheticisation of pain or the ambiguity between representing or concealing brutality, are the reference axes that serve as the basis on which wider issues linked to all representations of violence are addressed and a possible boundary between anxiety and horror is traced.El presente artículo indaga el límite entre el horror y lo siniestro a partir del ensayo Das Unheimliche, publicado por Sigmund Freud en 1919. El análisis se desarrolla a través de algunas de las imágenes vinculadas al conflicto armado colombiano, producidas por los artistas Juan Manuel Echavarría y Juan David Ortiz y el fotoperiodista Jesús Abad Colorado. Las nociones de realidad y ficción, así como los complejos dilemas en torno a la estetización del dolor o a la ambigüedad entre representar u ocultar la barbarie, son los ejes de referencia a partir de los cuales se abordan cuestiones más amplias vinculadas a toda representación de la violencia y se traza un posible límite entre la inquietud y el espanto

Uniform, luminescent Eu:LuF3 nanoparticles

A simple procedure for the synthesis of orthorhombic, uniform, LuF3 particles with two different morphologies (rhombus- and cocoon-like) and nanometer and sub-micrometer size, respectively, is reported. The method consists in the aging, at 120 °C for 2 h, a solution containing [BMIM]BF4 ionic liquid (0.5 mL) and lutetium acetate (in the case of the rhombi) or lutetium nitrate (in the case of the cocoons) (0.02 M) in ethylene glycol (total volume 10 mL). This synthesis method was also adequate for the synthesis of Eu3+-doped LuF3 particles of both morphologies, whose luminescence properties were investigated in detail. The experimental observations reported herein suggest that these materials are suitable phosphors for optoelectronic as well as in vitro biotechnological applications.MEC MAT2012-34919Junta de Andalucía JA FQM 06090CSIC 201460E00

Morphological and structural behavior of TiO2 nanoparticles in the presence of WO3: crystallization of the oxide composite system

Composite TiO2–WO3 oxide materials were prepared by a single pot microemulsion method and studied during calcination treatments under dry air in order to analyze the influence of tungsten on the behavior of the dominant titania component. To this end, the surface and bulk morphological and structural evolution of the solid precursors was studied using X-ray diffraction and infrared spectroscopy. In the calcination process, differences in the dominant titania component behavior appeared as a function of the W/Ti atomic ratio of the precursor. First, the crystallization of the anatase phase is affected by tungsten through an effect on the primary particle size growth. Furthermore, such an effect also influences the anatase to rutile phase transformation. The study provides evidence that the W–Ti interaction develops differently for a low/high W/Ti atomic ratio below/above 0.25 affecting fundamentally the above-mentioned anatase primary particle size growth process and the subsequent formation of the rutile phase and showing that addition of tungsten provides a way to control morphology and phase behavior in anatase-based oxide complex materialsComisión Interminsterial de Ciencia y Tecnología CT2010- 14872/BQUJunta de Andalucía FQM6090Consejo Superior de Investigaciones Científicas 201460E00

Tiny hand gesture recognition without localization via a deep convolutional network

Visual hand-gesture recognition is being increasingly desired for human-computer interaction interfaces. In many applications, hands only occupy about 10% of the image, whereas the most of it contains background, human face, and human body. Spatial localization of the hands in such scenarios could be a challenging task and ground truth bounding boxes need to be provided for training, which is usually not accessible. However, the location of the hand is not a requirement when the criteria is just the recognition of a gesture to command a consumer electronics device, such as mobiles phones and TVs. In this paper, a deep convolutional neural network is proposed to directly classify hand gestures in images without any segmentation or detection stage that could discard the irrelevant not-hand areas. The designed hand-gesture recognition network can classify seven sorts of hand gestures in a user-independent manner and on real time, achieving an accuracy of 97.1% in the dataset with simple backgrounds and 85.3% in the dataset with complex backgrounds
