Operational short term health impact assessment of air pollution modelling system over Europe

The last decade, scientific studies have indicated an association between air pollution to which people are exposed and wide range of adverse health outcomes. We have developed a tool which is based on a model (MM5-CMAQ) running over Europe with 50 km spatial resolution, based on EMEP annual emissions, to produce a short-term forecast of the impact on health. In order to estimate the mortality change (forecasted for the next 24 hours) we have chosen a log-linear (Poisson) regression form to estimate the concentration-response function. The parameters involved in the C-R function have been estimated based on epidemiological studies, which have been published. Finally, we have derived the relationship between concentration change and mortality change from the C-R function which is the final health impact function.

Self-Learning Embedded System for Object Identification in Intelligent Infrastructure Sensors

The emergence of new horizons in the field of travel assistant management leads to the development of cutting-edge systems focused on improving the existing ones. Moreover, new opportunities are being also presented since systems trend to be more reliable and autonomous. In this paper, a self-learning embedded system for object identification based on adaptive-cooperative dynamic approaches is presented for intelligent sensor’s infrastructures. The proposed system is able to detect and identify moving objects using a dynamic decision tree. Consequently, it combines machine learning algorithms and cooperative strategies in order to make the system more adaptive to changing environments. Therefore, the proposed system may be very useful for many applications like shadow tolls since several types of vehicles may be distinguished, parking optimization systems, improved traffic conditions systems, etc.

Fostering English-taught higher education programs in a Spanish university: the "TechEnglish" innovative project

In recent years, coinciding with adjustments to the Bologna process, many European universities have attempted to improve their international profile by increasing course offerings in English. According to the Institute of International Education (IIE), Spain has notably increased its English-taught higher education programs, ranking fifth in the list of European countries by number of English-taught Master's programs in 2013. This article presents the goals and preliminary results of an on-going innovative education project (TechEnglish) that aims to promote course offerings in English at the Technical University of Madrid (Universidad Politécnica de Madrid, UPM). The UPM is the oldest and largest of all Technical Universities in Spain. It offers graduate and postgraduate programs that cover all the engineering disciplines as well as architecture. Currently, the UPM has no specific bilingual/multilingual program to promote teaching in English, although there is an Educational Model Whitepaper (with a focus on undergraduate degrees) that promotes the development of activities like an International Semester or a unique shared curriculum. The TechEnglish project is an attempt to foster courses taught in English at 7 UPM Technical Schools, including students and 80 faculty members. Four tasks were identified: (1) to design a university wide framework to increase course offerings, (2) to identify administrative difficulties, (3) to increase visibility of courses offered, and (4) to disseminate the results of the project. First, to design a program we analyzed existing programs at other Spanish universities, and other projects and efforts already under way at the UPM. A total of 13 plans were analyzed and classified according to their relation with students (learning), professors (teaching), administration, course offerings, other actors/institutions within the university (e.g., language departments), funds and projects, dissemination activities, mobility plans and quality control. Second, to begin to identify administrative and organizational difficulties in the implementation of teaching in English, we first estimated the current and potential course offerings at the undergraduate level at the UPM using a survey (student, teacher and administrative demand, level of English and willingness to work in English). Third, to make the course offerings more attractive for both Spanish and international students we examined the way the most prestigious universities in Spain and in Europe try to improve the visibility of their academic offerings in English. Finally, to disseminate the results of the project we created a web page and a workspace on the Moodle education platform and prepared conferences and workshops within the UPM. Preliminary results show that increasing course offerings in English is an important step to promote the internationalization of the University. The main difficulties identified at the UPM were related to how to acknowledge/certify the departments, teachers or students involved in English courses, how students should register for the courses, how departments should split and schedule the courses (Spanish and English), and the lack of qualified personnel. A concerted effort could be made to increase the visibility of English-taught programs offered on-line.

ELEMENTOS DA OBRA FREIREANA E DA TEOLOGIA DA LIBERTAÇÃO NAS DÉCADAS DE 1950 A 1970: UMA ANÁLISE COMBINADA DE SUA GÊNESE E IDENTIDADE

A presente pesquisa se propõe a analisar o contexto histórico, político, social, econômico e ideológico em que surge a pedagogia crítica de Paulo Freire e posteriormente a Teologia da Libertação, visando encontrar influências deste peculiar contexto na gênese do pensamento freireano e nas concepções dos teólogos Rubem Alves e Gustavo Gutiérrez, que foram os primeiros publicar obras sobre Teologia da Libertação, corrente teológica considerada genuinamente latino-americana. Ainda procura observar em que medida as concepções pedagógicas de Freire podem ter sido acolhidas pelos teólogos Alves e Gutiérrez em suas obras aqui analisadas. Em ambos os pensamentos encontramos a visão de valorização do ser humano e de uma práxis que busca sua libertação de sistemas opressores. Tanto em Paulo Freire como nos fundamentos desta corrente teológica se apresentam princípios humanistas e elementos da tradição cristã. A partir da ferramenta metodológica de análise do materialismo histórico dialético marxista, procura identificar temas comuns que são abordados pelos autores em suas obras surgidas entre as décadas de 1950 a 1970, detendo-se ao estudo de alguns temas subjacentes a esse contexto histórico, a saber: práxis, história, humanismo e libertação.

Las rocas intrusivas y brechas del área de Los Molinos, Fuerteventura (Islas Canarias)

La presente tesis doctoral se centra en el estudio de las rocas intrusivas (plutónicas y filonianas) y brechas que afloran en el área de Los Molinos, localizada en la zona centro-occidental de la isla de Fuerteventura (Islas Canarias). Esta intrusión es de especial interés puesto que se localiza en la teórica zona de solape que habría existido entre los dos edificios volcánicos miocenos de mayor tamaño en Fuerteventura: el Edificio Volcánico Central y el Edificio Volcánico Norte, de modo que constituye un buen objetivo para determinar si cada edificio contaba con un sistema de alimentación independiente o si existe una situación más compleja a este respecto. En primer lugar se ha estudiado la estructura interna de la intrusión de Los Molinos, formada por distintas facies de gabros, de las cuales se han obtenido sus características petrográficas, mineralógicas y geoquímicas y se han determinado sus condiciones de presión y temperatura de cristalización, su edad y el tipo de fuente mantélica de la que proceden. Para ello se han realizado análisis químicos insitu mediante microsonda de electrones y láser ICP-MS, junto con análisis de roca total y de geoquímica isotópica. Los resultados obtenidos muestran que las diferentes facies de gabros que afloran en la intrusión están relacionadas genéticamente y que las facies más evolucionadas, leucogabros y venas félsicas, proceden de las facies menos diferenciadas, melanogabros y gabros olivínicos, mediante un proceso de cristalización fraccionada y acumulación. Las condiciones de presión y temperatura halladas indican que el proceso de cristalización tuvo lugar a altas temperaturas (1100-900 oC) y relativamente bajas presiones (3-1 Kb), en condiciones de moderada fO2. La edad de cristalización se determinó por el método U-Pb in-situ en apatito mediante láser ICP-MS, obteniéndose una edad media de cristalización de 17.4 ± 1.9 Ma para la intrusión de Los Molinos. Las relaciones isotópicas de Sr, Nd y Pb muestran que la fuente de la que proceden los magmas que dieron lugar a esta intrusión, es una mezcla entre los componentes mantélicos HIMU y DM con contribuciones menores del componente EMI...

Low metal content Co and Ni alumina supported catalysts for the CO2 reforming of methane

Low metal content Co and Ni alumina supported catalysts (4.0, 2.5 and 1.0 wt% nominal metal content) have been prepared, characterized (by ICP-OES, TEM, TPR-H2 and TPO) and tested for the CO2 reforming of methane. The objective is to optimize the metal loading in order to have a more efficient system. The selected reaction temperature is 973 K, although some tests at higher reaction temperature have been also performed. The results show that the amount of deposited carbon is noticeably lower than that obtained with the Co and Ni reference catalysts (9 wt%), but the CH4 and CO2 conversions are also lower. Among the catalysts tested, the Co(1) catalyst (the value in brackets corresponds to the nominal wt% loading) is deactivated during the first minutes of reaction because CoAl2O4 is formed, while Ni(1) and Co(2.5) catalysts show a high specific activity for methane conversion, a high stability and a very low carbon deposition.

Étude de l’orientation cardinale sud dans les sépultures mayas de la Période Classique

Ce mémoire porte sur l’étude de l’orientation des sépultures mayas de la Période Classique (250 - 900/1000 de notre ère). Il s’agit d’une recherche visant à comprendre le choix d’une orientation sud des défunts dans la vallée du Belize et ses environs. L’intérêt porté à cette région vient du fait que l’orientation sud des défunts est un phénomène que l’on retrouve rarement sur le territoire maya, sauf à cet endroit. Alors que la présence de la cardinalité en lien avec la cosmovision maya est attestée dans l’architecture, le plan des sites, la forme et la fonction des divinités, dans l’agriculture, etc., il est plutôt rare qu’elle soit analysée dans les études du traitement funéraire. Ainsi, le but de cette recherche est de saisir l’ampleur de la pratique de l’orientation sud des défunts sur le territoire maya, de comprendre son origine et sa ou ses possible(s) signification(s). Les données des sépultures de la Période Classique de cinq sites de la vallée du Belize (Baking Pot, Barton Ramie, Blackman Eddy, Cahal Pech et Xunantunich), de quatre sites du Plateau Vaca (Minanha, Pacbitun, Mountain Cow et Caracol) et de trois sites situés à l’ouest (Holmul) et au nord (San José et Altun Ha) de ces deux régions sont compilées. Les résultats révèlent que le coeur de cette pratique se trouve dans la vallée du Belize, bien qu’une orientation sud des défunts ait été retrouvée partout. Cette pratique semble apparaitre à la fin de la Période Préclassique et les analyses ne révèlent pas de lien entre l’orientation sud et certaines variables (âge, sexe, position du défunt). Finalement, on arrive à la conclusion qu’il est possible que cette orientation sud des défunts soit en lien avec le passage des défunts dans l’inframonde et que cela forme un choix culturel local en lien avec le statut et l’identité du défunt.
