Aprendizaje colaborativo en la enseñanza de la geología: el alumno hace de profesor

Una de las maneras más efectivas para asentar los conocimientos adquiridos se produce cuando, además de realizar un aprendizaje práctico, se intentan transmitir a otra persona. De hecho, los alumnos muchas veces prestan más atención a sus compañeros que al profesor. En la E.T.S.I. Minas de Madrid se ha llevado a cabo un programa de innovación educativa en asignaturas relacionadas con la Geología mediante nuevas tecnologías para mejorar el aprendizaje basado, principalmente, en el trabajo práctico personal y colectivo del alumno, con la realización de vídeos en el medio físico (campo) en los que explican los aspectos geológicos visibles a diferentes escalas. Estos vídeos se han subido a las plataformas ―moodle, ―facebook y canal ―youtube de la E.T.S.I. Minas donde compañeros, alumnos de otras Universidades y personas interesadas pueden consultarlos. De esta manera se pretende que, además de adquirir conocimientos geológicos, los alumnos adquieren el hábito de expresarse en público con un lenguaje técnico adecuado. Los alumnos manifestaron su satisfacción por esta actividad, aunque idea del rodaje de vídeos no resultó inicialmente muy popular debido a la inseguridad de los mismos. Se ha observado una mejora en los resultados de las calificaciones, así como un incremento de la motivación. De hecho, los estudiantes manifestaron haber adquirido, además de los conceptos geológicos, seguridad a la hora de expresarse en público empleando un lenguaje técnico

Unconformity-bounded stratigraphic units (UBSUs) in an italian alluvial-plain area: recognizing and dating

We studied the coastal zone of the Tavoliere di Puglia plain, (Puglia region, southern Italy) with the aim to recognize the main unconformities, and therefore, the unconformity-bounded stratigraphic units (UBSUs; Salvador 1987, 1994) forming its Quaternary sedimentary fill. Recognizing unconformities is particularly problematic in an alluvial plain, due to the difficulties in distinguishing the unconformities that bound the UBSUs. So far, the recognition of UBSUs in buried successions has been made mostly by using seismic profiles. Instead, in our case, the unavailability of the latter has prompted us to address the problem by developing a methodological protocol consisting of the following steps: I) geological survey in the field; II) draft of a preliminary geological setting based on the field-survey results; III) dating of 102 samples coming from a large number of boreholes and some outcropping sections by means of the amino acid racemization (AAR) method applied to ostracod shells and 14C dating, filtering of the ages and the selection of valid ages; IV) correction of the preliminary geological setting in the light of the numerical ages; definition of the final geological setting with UBSUs; identification of a ‘‘hypothetical’’ or ‘‘attributed time range’’ (HTR or ATR) for each UBSU, the former very wide and subject to a subsequent modification, the latter definitive; V) cross-checking between the numerical ages and/or other characteristics of the sedimentary bodies and/or the sea-level curves (with their effects on the sedimentary processes) in order to restrict also the hypothetical time ranges in the attributed time ranges. The successful application of AAR geochronology to ostracod shells relies on the fact that the ability of ostracods to colonize almost all environments constitutes a tool for correlation, and also allow the inclusion in the same unit of coeval sediments that differ lithologically and paleoenvironmentally. The treatment of the numerical ages obtained using the AAR method required special attention. The first filtering step was made by the laboratory (rejection criteria a and b). Then, the second filtering step was made by testing in the field the remaining ages. Among these, in fact, we never compared an age with a single preceding and/or following age; instead, we identified homogeneous groups of numerical ages consistent with their reciprocal stratigraphic position. This operation led to the rejection of further numerical ages that deviate erratically from a larger, homogeneous age population which fits well with its stratigraphic position (rejection criterion c). After all of the filtering steps, the valid ages that remained were used for the subdivision of the sedimentary sequences into UBSUs together with the lithological and paleoenvironmental criteria. The numerical ages allowed us, in the first instance, to recognize all of the age gaps between two consecutive samples. Next, we identified the level, in the sedimentary thickness that is between these two samples, that may represent the most suitable UBSU boundary based on its lithology and/or the paleoenvironment. The recognized units are: I) Coppa Nevigata sands (NEA), HTR: MIS 20–14, ATR: MIS 17–16; II) Argille subappennine (ASP), HTR: MIS 15–11, ATR: MIS 15–13; III) Coppa Nevigata synthem (NVI), HTR: MIS 13–8, ATR: MIS 12–11; IV) Sabbie di Torre Quarto (STQ), HTR: MIS 13–9.1, ATR: MIS 11; V) Amendola subsynthem (MLM1), HTR: MIS 12–10, ATR: MIS 11; VI) Undifferentiated continental unit (UCI), HTR: MIS 11–6.2, ATR: MIS 9.3–7.1; VII) Foggia synthem (TGF), ATR: MIS 6; VIII) Masseria Finamondo synthem (TPF), ATR: Upper Pleistocene; IX) Carapelle and Cervaro streams synthem (RPL), subdivided into: IXa) Incoronata subsynthem (RPL1), HTR: MIS 6–3; ATR: MIS 5–3; IXb) Marane La Pidocchiosa–Castello subsynthem (RPL3), ATR: Holocene; X) Masseria Inacquata synthem (NAQ), ATR: Holocene. The possibility of recognizing and dating Quaternary units in an alluvial plain to the scale of a marine isotope stage constitutes a clear step forward compared with similar studies regarding other alluvial-plain areas, where Quaternary units were dated almost exclusively using their stratigraphic position. As a result, they were generically associated with a geological sub-epoch. Instead, our method allowed a higher detail in the timing of the sedimentary processes: for example, MIS 11 and MIS 5.5 deposits have been recognized and characterized for the first time in the study area, highlighting their importance as phases of sedimentation.

New data on the Pleistocene of Trani (Adriatic Coast, Southern Italy)

Along the Apulian Adriatic coast, in a cliff south of Trani, a succession of three units (superimposed on one another) of marine and/or paralic environments has been recognised. The lowest unit I is characterised by calcareous/siliciclastic sands (css), micritic limestones (ml), stromatolitic and characean boundstones (scb), characean calcarenites (cc). The sedimentary environment merges from shallow marine, with low energy and temporary episodes of subaerial exposure, to lagoonal with a few exchanges with the sea. The lagoonal stromatolites (scb subunit) grew during a long period of relative stability of a high sea level in tropical climate. The unit I is truncated at the top by an erosion surface on which the unit II overlies; this consists of a basal pebble lag (bpl), silicicla - stic sands (ss), calcareous sands (cs), characean boundstones (cb), brown paleosol (bp). The sedimentary environment varies from beach to lagoon with salinity variations. Although there are indications of seismic events within the subunits cs, unit II deposition took place in a context of relative stability. The unit II is referable to a sea level highstand. Unit III, trangressive on the preceding, consists of white calcareous sands (wcs), calcareous sands and calcarenites (csc), phytoclastic calcirudite and phytohermal travertine (pcpt), mixed deposits (csl, m, k, c), sands (s) and red/brown paleosols (rbp). The sedimentation of this unit was affected by synsedimentary tectonic, attested by seismites found at several heights. Also the unit III is referable to a sea level highstand. The scientific literature has so far generally attributed to the Tyrrhenian (auct.) the deposits of Trani cliff. As part of this work some datings were performed on 10 samples, using the amino acid racemization method (AAR) applied to ostracod carapaces. Four of these samples have been rejected because they have shown in laboratory recent contamination. The numerical ages indicate that the deposits of the Trani cliff are older than MIS 5. The upper part of the unit I has been dated to 355±85 ka BP, thus allowing to assign the lowest stromatolitic subunit (scb) at the MIS 11 peak and the top of the unit I at the MIS 11-MIS 10 interval. The base of the unit II has been dated to 333±118 ka BP, thus attributing the erosion surface that bounds the units I and II to the MIS 10 lowstand and the lower part of the unit II to MIS 9.3. The upper part of the unit II has been dated to 234±35 ka BP, while three other numerical ages come from unit III: 303±35, 267±51, 247±61 ka BP. At present, the numerical ages cannot distinguish the sedimentation ages of units II and III, which are both related to the MIS 9.3- MIS 7.1 time range. However, the position of the units, superimposed one another, and their respective age, allows us to recognise a subsidence phase between MIS 11 and MIS 7, followed by an uplift phase between the MIS 7 and the present day, which led the deposits in their current position. This tectonic pattern is not in full agreement with what is described in the literature for the Apulian foreland.

Los alumnos manifestaron su satisfacción por esta actividad, aunque idea del rodaje de vídeos no resultó inicialmente muy popular. Se ha observado una mejora en las calificaciones, así como un incremento de la motivación. De hecho, los estudiantes manifestaron haber adquirido, además de los conceptos geológicos, seguridad a la hora de expresarse en público. Palabras clave: innovación educativa, nuevas tecnologías (TIC), Geología Abstract- Knowledge is gained by practice, but one of the most effective ways is when one tries to transmit it to others. Likewise, students pay more attention to their classmates than to teachers. In the Geological Engineering Department of the Madrid School of Mines, we have run an educational innovation program in courses related to Geology using new technologies (ITC) in order to increase the acquisition of geological knowledge. This program is designed mainly on the basis of individual and group work with video recordings in the field in which students explain geological concepts at various scales. These videos have been uploaded to the “Moodle”, “Facebook” and “YouTube” channel of the Madrid School of Mines, where other students from the same university or elsewhere can view them. Students acquire geological knowledge and the ability to address the general public using technical language. The realization of these videos has been warmly welcomed by students. Notably, they show increased motivation, accompanied by an improvement in grades, although at the beginning this program was not very popular because of student insecurity. Students have expressed that they learnt geological concepts but also gained confidence in public speaking using technical language

Performance analysis of a 7-kW crystalline silicon generator after 17 years of operation in Madrid

The degradation observed on a 7-kWp Si-x photovoltaic array after 17 years of exposure on the roof of the Solar Energy Institute of the Polytechnic University of Madrid is presented. The mean peak power degradation has been 9% over this time, or an equivalent to 0.53% per year, whereas peak power standard deviation has remained constant. The main visual defects are backsheet delamination at the polyester/polyvinyl fluoride outer interface and cracks in the terminal boxes and at the joint between the frame and the laminate. Insulation resistance complies well with the requirements of the International Electrotechnical Commission 61215 tests.

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.

La historia del oso de las cavernas: vida y muerte de un animal desaparecido

El título de este libro «La historia del oso de las cavernas: vida y muerte de un animal desaparecido» no es una feliz ocurrencia. Es una traducción del libro escrito por el paleontólogo fmés BjomKurten (1924-88) de la Universidad de Helsinki: The cave bear story: life and death of a vanished animal (Columbia University Press 1976) que, junto con innumerables artículos científicos, fueron inspiración de mi trabajo de investigación. No llegué a conocerle personalmente pero mantuve con él una relación epistolar y me ofreció sugerencias interesantes e, incluso, material en préstamo, el año de su muerte. El título del libro es más largo ya que reconcoce la contribución del yacimiento de Amutxate a esta historia. Como editor de este libro creo que, además de la satisfacción que me ha producido su escritura y coordinación, llega el momento de echar la vista atrás, recordar tantos buenos/malos momentos. He decidido hablar de buenos/malos momentos porque la espeleología, sea en su faceta científica o en la deportiva, consiste en una sucesión de vivencias en un ambiente hosti 1 que culmina con la satisfacción que produce el descubrimiento. En 1966 se produjo un hecho que marcó mi futuro participando en las exploraciones como miembro del GEM (Grupo Espeleológico de Minas) encontré mis primeros fósiles en la cueva del Reguerillo, cerca de Madrid. Esta cueva la excavé en 1971-1976 y, en años posteriores trabajé en otras muchas: Arrikrutz (Oñati, Guipúzcoa), Sima de los Huesos (Atapuerca, Burgos), Troskaeta (Ataun, Guipúzcoa), Los Osos (Tella-sin, Huesca), Eirós (Triacastela, Lugo ), La Lucia (Quintanilla, Cantabria), Santa Isabel (Ranero, Vizcaya) y, finalmente, Amutxate en la Sierra de Aralar.

A language exchange program: sustainability innovation in language and culture engagement

Spanish Educational Laws have been promoting the widespread use of English; as a result, Spanish Uni versities are looking for ways to give students more international training in order to prepare them for a future that will increasingly involve global problems and partnerships. Therefore, the Polytechnic University of Madrid, Spain (UPM), and the University of British Columbia, Okanagan, Canada (UBCO) have come together to offer opportunities for international collaboration and learning, thus facilitating virtual encounters among Spanish and Canadian students. The Language Exchange Program between the UPM and UBCO acts as a model for sustainability innovation in language and culture engagement as the students can interact with native speakers in communication tasks. This interdisciplinary initiative supports the latest methodological principles observed in the Common European Framework for Languages, such as autonomous and life-long learning, self-assessment and peer-assessment as well as the incorporation of new technologies to the learning process. Additionally the ‘virtual’ mobility is provided at no extra cost. This article presents the preliminary results of two virtual exchange programs that have been offering varied forms of study which are venue-independent, and have clearly expanded the range of scenarios for the students on both sides by promoting collaborative work and cultural exchange.
