Arrecifes de corales de aguas frías como posibles indicadores de emisiones de hidrocarburos en el banco de Galicia y determinación de su edad mediante racemizacion de aminoácidos

Este proyecto tiene como objetivo analizar la posible relación entre los corales de aguas frías encontrados en el Banco de Galicia con los procesos tectónicos y las estructuras relacionadas con la migración y la emisión de fluidos ricos en hidrocarburos (debido a su interés económico), así como la creación de un algoritmo que establezca una relación entre el grado de racemización sufrido por los aminoácidos de las muestras y la edad de estas. Para ello, se han recopilado datos y muestras en el área de estudio, gracias a los cuales se ha creado una base de datos que contiene una clasificación de las muestras recogidas junto a los datos más relevantes de que están relacionados con el objetivo de este trabajo. Estas muestras han sido proporcionadas por el IGME y fueron recogidas mayoritariamente en la campaña oceanográfica DIVA ARTABRIA II. Con estas muestras se han llevado a cabo análisis de laboratorio como el estudio de racemización de aminoácidos, el análisis de biomarcadores y la datación por uranio-torio de los esqueletos aragoníticos de los corales de aguas frías. Para finalizar, se han estudiado dichos datos con el objeto de comprobar la hipótesis de que los corales de aguas frías colonizan zonas con emisiones de hidrocarburos, conocer su edad y en última instancia crear un algoritmo capaz de datar dichos corales a partir del grado de racemización de sus aminoácidos. Palabras clave: corales de aguas frías, Banco de Galicia, campaña oceanográfica, DIVA ARTABRIA II, base de datos, racemización, aminoácidos, biomarcadores, datación uranio-torio, hidrocarburos, algoritmo. ABSTRACT This project studies the relationship between cold-water corals found in the Galicia Bank with tectonic processes and with the structures related to migration and hydrocarbon-rich fluids emissions. Firstly, data and samples in the study were collected, through to classify the collected samples with the most relevant characteristics to our research scope. Sampling and data collection provided by the IGME were collected in the DIVA ARTABRIA II oceanographic cruise. Secondly, the current work presents a systematic laboratory analysis that allowed the study of aminoacid racemization as well as the analysis of biomarkers and the uranium-thorium dating of aragonitic cold-water coral skeletons. Finally, this data was studied to test the hypothesis that cold-water corals colonize areas with emissions of hydrocarbons, know its age and ultimately create and algorithm capable of dating these corals from the degree of racemization in its amino acids. Keywords: cold-water corals, Galicia Bank, oceanographic cruise, DIVA ARTABRIA II, database, racemization, amino acids, biomarkers, uranium-thorium datation, hydrocarbons, algorithm.

Surface tension and microgravity

The behaviour of confined liquids on board an orbiting spacecraft is mainly driven by surface tension phenomena, which cause an apparently anomalous response of the liquid when compared with the behaviour that can be observed on an Earth laboratory provided that the amount of liquid is high enough. The reason is that in an orbiting spacecraft the different inertial forces acting on the bulk of the liquid are almost zero, causing thus capillary forces to be the dominant ones. Of course, since gravity forces are proportional to the liquid volume, whereas surface tension forces are proportional to the liquid surface, there are situations on Earth where capillarity can be the dominant effect, as it happens when very small volume liquid samples are considered. However, work with small size samples may require the use of sophisticated optical devices. Leaving aside the neutral buoyancy technique, a way of handling large liquid interfaces is by using drop towers, where the sample falls subjected to the action of Earth's gravity. This approach is suitable when the characteristic time of the problem under consideration is much smaller than the drop time. In this work the transformation of an out-of-use chimney into a drop tower is presented. Because of the miniaturization, hardiness and low cost of current electronic devices, a drop tower can be used as an inexpensive tool for undergraduate students to experimentally analyse a large variety of surface tension driven phenomena.

Active learning and generic competences in an operating systems course

The Bologna Declaration and the implementation of the European Higher Education Area are promoting the use of active learning methodologies. The aim of this study is to evaluate the effects obtained after applying active learning methodologies to the achievement of generic competences as well as to the academic performance. This study has been carried out at the Universidad Politécnica de Madrid, where these methodologies have been applied to the Operating Systems I subject of the degree in Technical Engineering in Computer Systems. The fundamental hypothesis tested was whether the implementation of active learning methodologies (cooperative learning and problem based learning) favours the achievement of certain generic competences (‘teamwork’ and ‘planning and time management’) and also whether this fact improved the academic performance of our students. The original approach of this work consists in using psychometric tests to measure the degree of acquired student’s generic competences instead of using opinion surveys, as usual. Results indicated that active learning methodologies improve the academic performance when compared to the traditional lecture/discussion method, according to the success rate obtained. These methods seem to have as well an effect on the teamwork competence (the perception of the behaviour of the other members in the group) but not on the perception of each students’ behaviour. Active learning does not produce any significant change in the generic competence ‘planning and time management'.

Desarrollo y evaluación de competencias genéricas en los títulos de grado.

Los nuevos títulos de grado en la Universidad española generados a raíz del proceso de Bolonia,inciden en una nueva dimensión: las competencias genéricas que deben adquirir los estudiantes universitarios. Pero ¿cómo armonizar el desarrollo y evaluación de dichas competencias con la actual actividad docente? En este trabajo se expone un modelo que permite la citada armonización con un mínimo de “ruido” y de esfuerzo complementario por parte de los docentes. En el modelo propuesto primero se hace una selección y una ordenación de las competencias que se quieren incorporar en un plan de estudios. Se hace una proyección de las competencias en los cuatrimestres y asignaturas del plan de estudios. La introducción de las competencias en las asignaturas asignadas se hace a través del diseño de actividades de formación, desarrollo y evaluación de la competencia. La segunda componente del modelo propuesto tiene por objeto coordinar las acciones que implementen la transversalidad de las competencias bajo desarrollo tanto en espacio como en tiempo. Por último, existen un conjunto de actividades destinadas a realizar el control de calidad del proceso propuesto. Este modelo se está implementado en las dos titulaciones de grado impartidas por la Escuela Universitaria de Informática de la Universidad Politécnica de Madrid durante el curso 2012/13. La coordinación se ha mostrado especialmente difícil dado la falta de experie ncia y el desconocimiento en este campo y las reticencias de algunos docentes a implicarse en este proceso. El modelo demuestra varias bondades: flexibilidad, aplicabilidad, extensibilidad, universalidad,globalidad y economía. ABSTRACT: The new degrees in Spanish University, generated as a result of the Bologna process, affect a new dimension: the generic competences to be acquired by university students. But, how can we harmonize the development and evaluation of these competencies with current teaching? This paper presents a model that allows the aforementioned harmonization with minimal "noise" and additional effort on the part of teachers. The proposed model first makes a selection and organization of competences that are to be incorporated into a curriculum. The following is a projection of competences in the semesters and curriculum subjects. The introduction of competences in the subjects assigned is carried out by designing activities of training, development and assessment. The second component of the proposed model is focused on coordinating actions to implement the transverse character of competences in both space and time. Finally, there are a set of activities to perform quality control of the proposed process. This model is being implemented in two degree taught by the School of Computer Science at the Universidad Politécnica de Madrid during the year 2012/13. Coordination has been particularly difficult given the lack of experience and lack of knowledge in this field and the reluctance of teachers to engage in this process.

University Networking in Developing Countries based on C4D-Learning

In recent years, the establishment of cooperation networks between universities is one of the most important trends in higher education all over the world. Well recognized local and international university networks have been implemented in most educational institutions. It is common to find associations of various prestigious universities collaborating in a high-­‐technology research project including a very specialized teaching as well. This is the most common cooperation networks among higher education institutions in developed countries. An increasingly common type of networking between developed and developing universities is related to cooperation for development. This is the case of many universities in Africa that are needed for external help in order to improve its capabilities. Numerous memorandums of understanding regarding first world institutions that collaborate with universities in developing countries describe contributions of eventual visiting professors, teaching material and courses. But probably there exist another type of more important, but less explored association, such as networking among developing universities. The new goal, in this case, is not only the excellence but also the mutual development.

Teamwork competence and academic motivation in computer science engineering studies.

The present work is focused on studying two issues: the “teamwork” generic competence and the “academic motivation”. Currently the professional profile of engineers has a strong component of teamwork. On the other hand, motivational profile of students determines their tendencies when they come to work in team, as well as their performance at work. In this context we suggest four hypotheses: (H1) students improve their teamwork capacity by specific training and carrying out a set of activities integrated into an active learning process; (H2) students with higher mastery motivation have better attitude towards team working; (H3) students with higher mastery motivation obtain better results in academic performance; and (H4) students show different motivation profiles in different circumstances: type of courses, teaching methodologies, different times of the learning process. This study was carried out with computer science engineering students from two Spanish universities. The first results point to an improvement in teamwork competence of students if they have previously received specific training in facets of that competence. Other results indicate that there is a correlation between the motivational profiles of students and their perception about teamwork competence. Finally, and contrary to the initial hypothesis, these profiles appear to not influence significantly the academic performance of students.

From Analysis Model to Software Architecture: a PIM2PIM Mapping.

To our knowledge, no current software development methodology explicitly describes how to transit from the analysis model to the software architecture of the application. This paper presents a method to derive the software architecture of a system from its analysis model. To do this, we are going to use MDA. Both the analysis model and the architectural model are PIMs described with UML 2. The model type mapping designed consists of several rules (expressed using OCL and natural language) that, when applied to the analysis artifacts, generate the software architecture of the application. Specifically the rules act on elements of the UML 2 metamodel (metamodel mapping). We have developed a tool (using Smalltalk) that permits the automatic application of these rules to an analysis model defined in RoseTM to generate the application architecture expressed in the architectural style C2.

UML 1.4 versus UML 2.0 as Languages to Describe Software Architectures.

ML 1.4 is widely accepted as the standard for representing the various software artifacts generated by a development process. For this reason, there have been attempts to use this language to represent the software architec- ture of systems as well. Unfortunately, these attempts have ended in representa- tions (boxes and lines) already criticized by the software architecture commu- nity. Recently, OMG has published a draft that will constitute the future UML 2.0 specification. In this paper we compare the capacities of UML 1.4 and UML 2.0 to describe software architectures. In particular, we study extensions of both UML versions to describe the static view of the C3 architectural style (a simplification of the C2 style). One of the results of this study is the difficulties found when using the UML 2.0 metamodel to describe the concept of connector in a software architecture.
