Balanced scorecard to improve strategic management control at School of Mines and Energy, Universidad Politécnica de Madrid

We studied the situation in Spanish public universities regarding the use of the Balanced Scorecard (BSC), as an instrument of control and strategic management. Also, we studied its application to the School of Mines and Energy at Universidad Politécnica de Madrid. The main advantage of the BSC is that improves the organizational structure of the workplace and the achievement of the objectives that ensure long-term success. First we review the strategy for success used in the Spanish educational system and specifically in the Spanish public universities. Then using the BSC and applying the main strategic lines for the successful management of the School of Mines and Energy at Universidad Politécnica de Madrid. The strategic lines affect all the college groups and the success of the BSC tool is to increase communication between the faculties, personal auxiliary, students and society in general that make up the university. First we performed a SWOT analysis (DAFO in Spanish) there are proposed different perspectives that focus the long-term strategic objectives. The BSC is designed based on the strategic objectives that set the direction through using indicators and initiatives, the goals are achieved up to the programmed schedule. In the perspective of teaching, objectives are set to update facilities and increase partnerships with other universities and businesses, encouraging ongoing training of staff and improved coordination and internal communication. The internal process perspective aims at improving the marketing, the promotion of the international dimension of the school through strategic alliances, better mobility for students and professors and improved teaching and research quality results. It continues with improving the image of the school between customer?s perspective, the quality perceived by students and the loyalty of the teaching staff by retaining talent. Finally, the financial perspective which should contain costs without harming the quality, improving the employability of students and achieve relevant jobs at teaching and research through international measurement standards.

Probabilistic assessment of risk from the exposure to mercury in artisanal gold mining communities in Colombia

Colombia is one the largest per capita mercury polluters as a consequence of its artisanal gold mining operations, which are steadily increasing following the rising price of this metal. Compared to gravimetric separation methods and cyanidation, the concentration of gold using Hg amalgams presents several advantages: the process is less time-consuming and minimizes gold losses, and Hg is easily transported and inexpensive relative to the selling price of gold. Very often, mercury amalgamation is carried out on site by unprotected workers. During this operation large amounts of mercury are discharged to the environment and eventually reach the fresh water bodies in the vicinity where it is subjected to methylation. Additionally, as gold is released from the amalgam by heating on open charcoal furnaces in small workshops, mercury vapors are emitted and inhaled by the artisanal smelters and the general population

Application of protection means against explosions in underground mines

Underground coal mines explosions generally arise from the inflammation of a methane/air mixture. This explosion can also generate a subsequent coal dust explosion. Traditionally such explosions have being fought eliminating one or several of the factors needed by the explosion to take place. Although several preventive measures are taken to prevent explosions, other measures should be considered to reduce the effects or even to extinguish the flame front. Unlike other protection methods that remove one or two of the explosion triangle elements, namely; the ignition source, the oxidizing agent and the fuel, explosion barriers removes all of them: reduces the quantity of coal in suspension, cools the flame front and the steam generated by vaporization removes the oxygen present in the flame. The present paper is essentially based on the comprehensive state-of–the-art of Protective Systems in underground coal mines, and particularly on the application of Explosion Barriers to improve safety level in Spanish coal mining industry. After an exhaustive study of series EN 14591 standards covering explosion prevention and protection in underground mines, authors have proven explosion barriers effectiveness in underground galleries by Full Scale Tests performed in Polish Barbara experimental mine, showing that the barriers can reduce the effects of methane and/or flammable coal dust explosions to a satisfactory safety level.

La Planificación de Áreas Mineras en Declive : Una respuesta multidimensional = Planning Declining Mining Areas. A multidimensional response

La actividad minera tiene un gran impacto sobre el territorio, probablemente más que ninguna otra de las actividades humanas, ya que transforma el espacio en todas sus dimensiones: ecológica, ambiental, social y económica. Cuando la reducción de la rentabilidad de la explotación conduce al cierre de ésta, la repercusión sobre su entorno puede llegar a ser brutal. Pero las explotaciones mineras son muy distintas entre ellas y los efectos que su abandono producen sobre el espacio en la que se enclavan pueden ser diversos, por lo que la decisión sobre el futuro de estas áreas no es simple y evidente. Aquí se propone desarrollar una propuesta de clasificación tipológica de las minas y sus regiones con el objetivo de determinar las estrategias de intervención más adecuadas para el futuro de estos espacios y sus habitantes. En concreto se busca diferenciar los conceptos de Mina, Parque Minero, Espacio Minero y Región Minera, todos ellos fruto de la interacción de la huella de la actividad minera con el medio físico, los enclaves urbanizados, y la estructura socioeconómica de la región en la que se enclavan. Mining activity is having a great impact on the territory, probably more than any other human activity, which transforms the space in all of its dimensions, ecological, environmental, social and economic. When reducing the profitability of the operation leads to the conclusion thereof, the impact on the environment can be brutal. But mining are very different between them and the effects they produce on their abandonment in space that interlock can be diverse, so the decision on the future of these areas is not simple and obvious. This proposal aims to develop a typological classification of mines and their regions in order to determine the most appropriate intervention strategies for the future of these spaces and their inhabitants. Specifically, it seeks to differentiate the concepts of Mine, Mining Park, Space Miner and Mining Region, all the result of the interaction of the mining footprint with the physical environment, the urbanized enclaves, and the socio-economic structure of the region which interlock.

Las mineralizaciones auríferas de Galicia Occidental en la Zona de Cizalla Busto-Limideiro (A Coruña)

Las mineralizaciones de oro de Galicia Occidental ligadas a grandes estructuras comienzan a ser interpretadas de manera más rigurosa, al mismo tiempo que la continuada elevación de las cotizaciones del oro han hecho más atractiva la reactivación de áreas hasta ahora casi olvidadas. El propósito de esta investigación participa de las razones anteriores. La zona de cizalla Busto Limideiro se inscribe en una de estas estructuras, la cizalla Santa Comba-Punta Langosteira, con la que se relacionan un importante número de yacimientos auríferos entre los que destacan Corcoesto y Monte Piñor. Por su situación geológica, estos indicios se enmarcan en el Macizo Ibérico, en la Zona de Galicia Tras-os-Montes. Este trabajo aporta más conocimiento sobre un modelo general del oro de los yacimientos del noroeste español, integrándolo en los yacimientos de oro orogénico del Varisco europeo. Este estudio ha supuesto un importante esfuerzo investigador centrado sobre de los procesos genéticos que han dado lugar a las mineralizaciones auríferas. Los estudios petrográficos, metalogénicos, geoquímicos, microtemométricos y el análisis de isótopos han permitido establecer un modelo general y otros más específicos sobre la existencia y condiciones de formación en la concentración del oro mineralógico. De esta forma se ha caracterizado su mineralogía, quimismo, edad, y naturaleza de los paleofluidos que han intervinieron en su formación. De los resultados obtenidos se destaca que estas mineralizaciones se encuentran fuertemente ligadas a las estructuras y transformaciones físicas y químicas de las rocas afectadas por la banda de cizalla. Derivada de esta situación, se comprende la disposición espacial, a diversas escalas, con estructuras claramente en la transición del dominio dúctil a frágil. Además, resulta evidente, a escala macro y microscópica, el emplazamiento preferente del oro en estructuras de deformación miloníticas. Los estudios anteriores posibilitan formalizar un modelo de génesis para el yacimiento de Monte Piñor que resulta compatible con el establecido por Groves (1998), e incluirlas en un mismo contexto, como yacimientos de oro orogénico mesotermales, válido para el conjunto de todos los de la zona de cizalla Busto Limideiro. El estudio no omite la consideración geoestadística de este yacimiento, justificando la elección de direcciones de anisotropía explicadas por consideraciones de carácter estructural. Con ello, buscando el lado práctico desde el punto de vista minero, esta investigación propone líneas generales de aplicación de actuación con sentido de exploración, contribuyendo a la puesta en valor del conocimiento de las mineralizaciones de oro del noroeste español. ABSTRACT Old and nearly forgotten gold mines from Western Galicia are currently attractive to be recovered due to both, the new strict interpretation of gold mineralization linked to Variscan large structures and the increasing gold prices. The shear zone Busto Limiderio is relevant as a part of a Variscan large structure, Santa Comba-Punta Langosteira, which is related with a high number of gold deposits as Corcoesto and Monte Piñor. For its geological situation, these signs are part of the Iberian Massif in the area of Galicia Tras-os-Montes. Hence, the main aim of this study is to provide additional and important knowledge of Busto Limiderio about the general model of gold deposits in the Spanish northwest, integrating them in the orogenic gold deposits of European Variscan, enabling to analyze the economic recovery possibility of this area. This thesis has been focused on the genetic processes that have led to the gold mineralization. Petrographic studies, metalogenic, geochemical, microthermometric and isotope analysis have allowed to establish a general and specific models about the existence and training conditions in the concentration of mineralogical gold. Consequently, the mineralogy, chemical characteristics, age, and nature of paleofluids that have participated in its formation have been characterized. The results showed that Busto Limiderio gold mineralization are strongly linked to the structures and physical and chemical transformations of affected rocks by the shear band. The mineralization spatial distribution at various scales is due to the link with the large structures in the ductile-to-brittle transition domain. Furthermore, this factor determine at macro and microscopic scale, the preferred location of the gold structures mylonitic deformation. Previous studies have permitted to establish a model of genesis for the site of Monte Piñor which is compatible with the established by Groves (1998), and also to include them in the same context as mesothermal orogenic gold deposits, valid throughout all of Busto Limideiro shear zone. This study does not omit consideration of the geostatistical deposit, justifying the choice of directions of anisotropy explained by structural considerations. This thesis concludes with general action guidelines for mining exploration, contributing to the enhancement of knowledge of Spanish gold mineralization northwest.

Thermal and mechanical effects of different excitation modes based on low frequency laser modulation in optical hyperthermia

The low frequency modulation of the laser source (menor que30KHz) allows the generation of a pulsed signal that intermittently excites the gold nanorods. The temperature curves obtained for different frequencies and duty cycles of modulation but with equal average power and identical laser parameters, show that the thermal behavior in continuous wave and modulation modes is the same. However, the cell death experiments suggest that the percentage of death is higher in the cases of modulation. This observation allows us to conclude that there are other effects in addition to temperature that contribute to the cellular death. The mechanical effects like sound or pressure waves are expected to be generated from thermal expansion of gold nanorods. In order to study the behavior and magnitude of these processes we have developed a measure device based on ultrasound piezoelectric receivers (25KHz) and a lock-in amplifier that is able to detect the sound waves generated in samples of gold nanorods during laser irradiation providing us a voltage result proportional to the pressure signal. The first results show that the pressure measurements are directly proportional to the concentration of gold nanorods and the laser power, therefore, our present work is focused on determine the real influence of these effects in the cell death process.

Los espacios mineros abandonados. El caso de la Comunidad de Madrid

La Comunidad de Madrid ha tenido un pasado minero importante que ha dejado su vestigio en el territorio. Actualmente la explotación de minerales no metálicos y de rocas industriales y ornamentales continúa, pero no así la de la minería metálica que en el pasado fue abundante. Hoy en día todas estas minas están abandonadas, dando lugar a zonas degradadas con un elevado riesgo para la seguridad de las personas y de los animales terrestres que habitan por sus inmediaciones, y necesitan ser intervenidas atendiendo, además, a su integración o recuperación ecológica y paisajística en el territorio. El principal propósito de esta tesis es conocer la situación actual que presentan las minas abandonadas de metales y proponer unos modelos de actuación para la rehabilitación e integración de los espacios mineros abandonados de la Comunidad de Madrid, cuya ventaja también estriba en su posible extrapolación a otras aéreas de gestión con una problemática similar. Partiendo de una selección de cincuenta y siete minas de interior metálicas abandonadas, se ha hecho un diagnostico en función de su seguridad (riesgo), interés cultural, arqueológico e histórico y por su afección a espacios protegidos, resultando que en todas, excepto en tres de ellas, es preciso llevar a cabo medidas protectoras y de restauración e integración en el medio ambiente. El conjunto de minas catalogadas de alto riesgo para la seguridad son veintitrés, y sobre ellas se ha realizado un Análisis Clúster, en el que además de los criterios de gestión formulados: seguridad, protección del patrimonio minero-industrial e integración ecológico-paisajística, se han incorporado otros modificadores como distancia a poblaciones, caminos, pistas y vías pecuarias, y accesibilidad. Con los resultados de este análisis se obtienen una clasificación por grupos de las minas en relación con las características intrínsecas de las explotaciones preseleccionadas y la tipología de problemas que presentan, y a partir de ella se plantean soluciones viables que se concretan en la redacción de una serie de anteproyectos tipo. Una de las principales aportaciones es que se trata de un modelo de inventariocaracterización- actuación extrapolable a otros entornos similares con problemáticas parecidas. Las propuestas de actuación que figuran en los anteproyectos tipo se proponen como medidas aplicables en situaciones similares. La tesis además también incorpora una base de datos georreferenciada que permite la localización de las explotaciones mineras abandonadas, el acceso rápido a sus características y a la propuesta de restauración correspondiente. ABSTRACT The Community of Madrid had an important mining past that left its traces in the territory. Currently the explotation of non-metallic minerals and industrial and ornamental rocks continues, but not so much with the metal deposits that were abundant in the past. Today these mines are abandoned, resulting in degraded areas with a high risk to the safety of nearby people and animals that inhabit its vicinity, and they need to be intervened, by tending to their environment integration or ecological and landscape recovery. The main objective of this thesis is to know the current situation of abandoned metal mines and propose an action model for the rehabilitation and integration of abandoned mining areas of the Community of Madrid, whose advantage also is its possible extrapolation to other management areas with similar problems. From a selection of fifty-seven abandoned metal mines, a diagnosis has been made, based on safety (risk), cultural, archaeological and historical interests and how it can be related to protected areas, resulting that all but three of them need measures of protection, restoration and integration to the environment. The set of mines that are classified as a high security risk are twenty-three, and it has been made on them an Cluster Analysis, as in addition to the management formulated criteria, such as safety, protection of mining and industrial heritage and eco-landscape integration, it has been incorporated other modifying variables, such as distance to populations, roads, tracks and livestock paths, and accessibility. With the results of this analysis, a classification of similar groups of mines in relation with the intrinsic characteristics of the preselected mines and typology problems, and from it a set of viable solutions will be specified, being then drafted on a series of proposals. One of the main contributions of this research is that it consists of an inventorycharacterization- action model, which can be extrapolated to other similar environments with similar problems. The action measures that are contained in the proposals are defined as applicable to similar situations. The thesis also incorporates a geo-referenced database that allows finding the location of abandoned mines, thus giving quick access to its features and its corresponding restoration proposal.

Discourses and values underpin public debate on fracking in Spain: a case study at the crossroad

In the EU context extraction of shale and oil gas by hydraulic fracturing (fracking) differs from country to country in terms of legislation and implementation. While fossil fuel extraction using this technology is currently taking place in the UK, Germany and France have adopted respective moratoria. In between is the Spanish case, where hydrocarbon extraction projects through fracking have to undergo mandatory and routine environmental assessment in accordance with the last changes to environmental regulations. Nowadays Spain is at the crossroad with respect to the future of this technology. We presume a social conflictt in our country since the position and strategy of the involved and confronted social actors -national, regional and local authorities, energy companies, scientists, NGO and other social organization- are going to play key and likely divergent roles in its industrial implementation and public acceptance. In order to improve knowledge on how to address these controverted situations from the own engineering context, the affiliated units from the Higher Technical School of Mines and Energy Engineering at UPM have been working on a transversal program to teach values and ethics. Over the past seven years, this pioneering experience has shown the usefulness of applying a consequentialist ethics, based on a case-by-case approach and costs-benefits analysis both for action and inaction. As a result of this initiative a theoretical concept has arisen and crystallized in this field: it is named Inter-ethics. This theoretical perspective can be very helpful in complex situations, with multi-stakeholders and plurality of interests, when ethical management requires the interaction between the respective ethics of each group; professional ethics of a single group is not enough. Under this inter-ethics theoretical framework and applying content analysis techniques, this paper explores the articulation of the discourse in favour and against fracking technology and its underlying values as manifested in the Spanish traditional mass media and emerging social media such as Youtube. Results show that Spanish public discourse on fracking technology includes the costs-benefits analysis to communicate how natural resources from local communities may be affected by these facilities due to environmental, health and economic consequences. Furthermore, this technology is represented as a solution to the "demand of energy" according to the optimistic discourse while, from a pessimistic view, fracking is often framed as a source "environmental problems" and even natural disasters as possible earthquakes. In this latter case, this negative representation could have been influenced by the closure of a macro project to store injected natural gas in the Mediterranean Sea using the old facilities of an oil exploitation in Amposta (Proyecto Cástor). The closure of this project was due to the occurrence of earthquakes whose intensity was higher than the originally expected by the experts in the assessment stage of the project.
