The main objective of this course, conducted by Jóvenes Nucleares (Spanish Young Generation in Nuclear, JJNN), a non-profit organization that depends on the Spanish Nuclear Society (SNE) is to pass on basic knowledge about Science and Nuclear Technology to the general public, mostly students and introduce them to its most relevant points. The purposes of this course are to provide general information, to answer the most common questions about Nuclear Energy and to motivate the young students to start a career in nuclear. Therefore, it is directed mainly to high school and university students, but also to general people that wants to learn about the key issues of such an important matter in our society. Anybody could attend the course, as no specific scientific education is required. The course is done at least once a year, during the Annual Meeting of the Spanish Nuclear Society, which takes place in a different Spanish city each time. The course is done also to whichever university or institution that asks for it to JJNN, with the only limit of the presenter´s availability. The course is divided into the following chapters: Physical nuclear and radiation principles, Nuclear power plants, Nuclear safety, Nuclear fuel, Radioactive waste, Decommission of nuclear facilities, Future nuclear power plants, Other uses of nuclear technology, Nuclear energy, climate change and sustainable development. The course is divided into 15 minutes lessons on the above topics, imparted by young professionals, experts in the field that belongs either to the Spanish Young Generation in Nuclear, either to companies and institutions related with nuclear energy. At the end of the course, a 200 pages book with the contents of the course is handed to every member of the audience. This book is also distributed in other course editions at high schools and universities in order to promote the scientific dissemination of the Nuclear Technology. As an extra motivation, JJNN delivers a course certificate to the assistants. At the end of the last edition course, in Santiago de Compostela, the assistants were asked to provide a feedback about it. Some really interesting lessons were learned, that will be very useful to improve next editions of the course. As a general conclusion of the courses it can be said that many of the students that have assisted to the course have increased their motivation in the nuclear field, and hopefully it will help the young talents to choose the nuclear field to develop their careers

Around ten years ago investigation of technical and material construction in Ancient Roma has advanced in favour to obtain positive results. This process has been directed to obtaining some dates based in chemical composition, also action and reaction of materials against meteorological assaults or post depositional displacements. Plenty of these dates should be interpreted as a result of deterioration and damage in concrete material made in one landscape with some kind of meteorological characteristics. Concrete mixture like calcium and gypsum mortars should be analysed in laboratory test programs, and not only with descriptions based in reference books of Strabo, Pliny the Elder or Vitruvius. Roman manufacture was determined by weather condition, landscape, natural resources and of course, economic situation of the owner. In any case we must research the work in every facts of construction. On the one hand, thanks to chemical techniques like X-ray diffraction and Optical microscopy, we could know the granular disposition of mixture. On the other hand if we develop physical and mechanical techniques like compressive strength, capillary absorption on contact or water behaviour, we could know the reactions in binder and aggregates against weather effects. However we must be capable of interpret these results. Last year many analyses developed in archaeological sites in Spain has contributed to obtain different point of view, so has provide new dates to manage one method to continue the investigation of roman mortars. If we developed chemical and physical analysis in roman mortars at the same time, and we are capable to interpret the construction and the resources used, we achieve to understand the process of construction, the date and also the way of restoration in future.

European Universities are involved in series of great changes regarding teaching and education organization during the last few years. The origin of these changes is the creation of the so-called European Higher Education Area (EHEA), which main target is to harmonize the different University studies throughout Europe. As a consequence, most of the programs of studies in all degrees are suffering changes in order to converge to common structures. Taking advantage of the actual process, some European universities are moving from traditional Agricultural Engineering programs to a more wide discipline named recently as Biosystems Engineering, which is a science- based engineering discipline that integrates engineering science and design with applied biological, environmental and agricultural sciences, broadening in this way the area of application of Engineering sciences not strictly to agricultural sciences, but to the biologic al sciences in general, including the agricultural sciences. This paper presents a comparative study of different Bachelor of Science degrees offered by American and European Universities in the field of Agricultural/Biosystems Engineering. To carry out the analysis 40 programs accredited by ABET in American Universities and 50 European programs. Among other questions, the total number of credits, the number of semesters, the kind of modules and the distribution of subjects in groups (Basic Sciences, Engineering Fundamentals, Agricultural/Biological Sciences, Humanities & Economic Sciences, Applied Agricultural/Biological Engineering and electives) are discussed in the paper. The information provided can be an useful starting point in future definitions of new or renewed degrees with the aim of advancing in internationalization of the programs and helping student’s mobility.

The problem is general: modern architects and engineers are trying to understand historic structures using the wrong theoretical frame, the classic (elastic) thery of structures developed in the 19th Century for iron and stell, and in the 20th century for reinforced concrete, disguised with "modern" computer packages, mainly FEM, but also others. Masonry is an essentially different material, and the structural equations must be adapted accordingly. It is not a matter of "taste" or "opinion", and the consequences are before us. Since, say 1920s, historic monuments have suffered the aggression of generations of archietcts and engineers, trying to transform masonry in reinfored concrete or steel. The damage to the monuments and the expense has been, and is, enormous. However, as we have an adequate theory (modern limit analysis of masonry structures, Heyman 1966) which encompasses the "old theory" used successfully by the 18th and 19th Century practical engineers (from Perronet to Sejourné), it is a matter of "Ethics" not to use the wrong approach. It is also "contra natura" to modify the material masonry with indiscriminate injections, stitchings, etc. It is insane to consider, suddenly, that buildings which are Centuries or milennia old, are suddenly in danger of collapse. Maintenance is necessary but not the actual destruction of the constructive essence of the monument. A cocktail of "ignorance, fear and greed" is acting under the best of intentions.

In the world of information and communications technologies the demand for professionals with software engineering skills grows at an exponential rate. On this ground, we have conducted a study to help both academia and the software industry form a picture of the relationship between the competences of recent graduates of undergraduate and graduate software engineering programmes and the tasks that these professionals are to perform as part of their jobs in industry. Thanks to this study, academia will be able to observe which skills demanded by industry the software engineering curricula do or do not cater for, and industry will be able to ascertain which tasks a recent software engineering programme graduate is well qualified to perform. The study focuses on the software engineering knowledge guidelines provided in SE2004 and GSwE2009, and the job profiles identified by Career Space.

The core concepts, or threads, of Biosystems Engineering (BSEN) are variously understood by those within the discipline, but have never been unequivocally defined due to its early stage of development. This makes communication and teaching difficult compared to other well established engineering subjects. Biosystems Engineering is a field of Engineering which int egrates engineering science and design with applied biological, environmental and agricultural sciences. It represents an evolution of the Agricultural Engineering discipline applied to all living organisms not including biomedical applications. The basic key element for the emerging EU Biosystems Engineering program of studies is to ensure that it offers essential minimum fundamental engine ering knowledge and competences . A core curriculum developed by Erasmus Thematic Networks is used as benchmark for Agr icultural and Biosystems Engineering studies in Europe. The common basis of the core curriculum for the discipline across the Atlantic , including a minimum of competences comprising the Biosystems Engineering core competencies, has been defined by an Atlan tis project , but this needs to be taken further by defining the threads linking courses together. This paper presents a structured approach to define the Threads of BSEN . The definition of the mid-level competences and the associated learning outcomes has been one of the objectives of the Atlantis programme TABE.NET. The mid-level competences and learning outcomes for each of six specializations of BSEN are defined while the domain-specific knowledge to be acquired for each outcome is proposed. Once the proposed definitions are adopted, these threads will be available for global development of the BSEN.

A theory is developed of an electrostatic probe in a fully-ionized plasma in the presence of a strong magnetic field. The ratio of electron Larmor radius to probe transverse dimension is assumed to be small. Poisson's equation, together with kinetic equations for ions and electrons are considered. An asymptotic perturbation method of multiple scales is used by considering the characteristic lengths appearing in the problem. The leading behavior of the solution is found. The results obtained appear to apply to weaker fields also, agreeing with the solutions known in the limit of no magnetic field. The range of potentials for wich results are presented is limited. The basic effects produced by the field are a depletion of the plasma near the probe and a non-monotonic potential surrounding the probe. The ion saturation current is not changed but changes appear in both the floating potential Vf and the slope of the current-voltage diagram at Vf. The transition region extends beyond the space potential Vs,at wich point the current is largely reduced. The diagram does not have an exponential form in this region as commonly assumed. There exists saturation in electron collection. The extent to which the plasma is disturbed is determined. A cylindrical probe has no solution because of a logarithmic singularity at infinity. Extensions of the theory are considered.

Cognitive linguistics is considered as one of the most appropriate approaches to the study of scientific and technical language formation and development, where metaphor is accepted to play an essential role. This paper, based on the Cognitive Theory of Metaphor, takes as the starting point the terminological metaphors established in the research project METACITEC(Note 1), which was developed with the purpose of unfolding constitutive metaphors and their function in the language of science and technology. After the analysis of metaphorical terms and using a mixed corpus from the fields of Agriculture, Geology, Mining, Metallurgy, and other related technical fields, this study presents a proposal for a hierarchy of the selected metaphors underlying the scientific conceptual system, based on the semantic distance found in the projection from the source domain to the target domain. We argue that this semantic distance can be considered as an important parameter to take into account in order to establish the metaphoricity of science and technology metaphorical terms. The findings contribute to expand on the CTM stance that metaphor is a matter of cognition by reviewing the abstract-concrete conceptual relationship between the target and source domains, and to determine the role of human creativity and imagination in the language of science and technology configuration

Esta investigación recoge un cúmulo de intereses en torno a un modo de generar arquitectura muy específico: La producción de objetos con una forma subyacente no apriorística. Los conocimientos expuestos se apoyan en condiciones del pensamiento reciente que impulsan la ilusión por alimentar la fuente creativa de la arquitectura con otros campos del saber. Los tiempos del conocimiento animista sensible y el conocimiento objetivo de carácter científico son correlativos en la historia pero casi nunca han sido sincrónicos. Representa asimismo un intento por aunar los dos tipos de conocimiento retomando la inercia que ya se presentía a comienzos del siglo XX. Se trata por tanto, de un ensayo sobre la posible anulación de la contraposición entre estos dos mundos para pasar a una complementariedad entre ambos en una sola visión conjunta compartida. Como meta final de esta investigación se presenta el desarrollo de un sistema crítico de análisis para los objetos arquitectónicos que permita una diferenciación entre aquellos que responden a los problemas de manera completa y sincera y aquellos otros que esconden, bajo una superficie consensuada, la falta de un método resolutivo de la complejidad en el presente creativo. La Investigación observa tres grupos de conocimiento diferenciados agrupados en sus capítulos correspondientes: El primer capítulo versa sobre el Impulso Creador. En él se define la necesidad de crear un marco para el individuo creador, aquel que independientemente de las fuerzas sociales del momento presiente que existe algo más allá que está sin resolver. Denominamos aquí “creador rebelde” a un tipo de personaje reconocible a lo largo de la Historia como aquel capaz de reconocer los cambios que ese operan en su presente y que utiliza para descubrir lo nuevo y acercarse algo al origen creativo. En el momento actual ese tipo de personaje es el que intuye o ya ha intuido hace tiempo la existencia de una complejidad creciente no obviable en el pensamiento de este tiempo. El segundo capítulo desarrolla algunas Propiedades de Sistemas de actuación creativa. En él se muestra una investigación que desarrolla un marco de conocimientos científicos muy específicos de nuestro tiempo que la arquitectura, de momento, no ha absorbido ni refleja de manera directa en su manera de crear. Son temas de presencia casi ya mundana en la sociedad pero que se resisten a ser incluidos en los procesos creativos como parte de la conciencia. La mayoría de ellos hablan de precisión, órdenes invisibles, propiedades de la materia o la energía tratados de manera objetiva y apolítica. La meta final supone el acercamiento e incorporación de estos conceptos y propiedades a nuestro mundo sensible unificándolos indisociablemente bajo un solo punto de vista. El último capítulo versa sobre la Complejidad y su capacidad de reducción a lo esencial. Aquí se muestran, a modo de conclusiones, la introducción de varios conceptos para el desarrollo de un sistema crítico hacia la arquitectura de nuestro tiempo. Entre ellos, el de Complejidad Esencial, definido como aquella de carácter inevitable a la hora de responder la arquitectura a los problemas y solicitaciones crecientes a los que se enfrenta en el presente. La Tesis mantiene la importancia de informar sobre la imposibilidad en el estado actual de las cosas de responder de manera sincera con soluciones de carácter simplista y la necesidad, por tanto, de soluciones necesarias de carácter complejo. En este sentido se define asimismo el concepto de Forma Subyacente como herramienta crítica para poder evaluar la respuesta de cada arquitectura y poder tener un sistema y visión crítica sobre lo que es un objeto consistente frente a la situación a la que se enfrenta. Dicha forma subyacente se define como aquella manera de entender conjuntamente y de manera sincrónica aquello que percibimos de manera sensible inseparable de las fuerzas ocultas, creativas, tecnológicas, materiales y energéticas que sustentan la definición y entendimiento de cualquier objeto construido. ABSTRACT This research includes a cluster of interests around a specific way to generate architecture: The production of objects without an a priori underlying form. The knowledge presented is based on current conditions of thought promoting the illusion to feed the creative source of architecture with other fields of knowledge. The sensible animist knowledge and objective scientific knowledge are correlative in history but have rarely been synchronous. This research is also an attempt to combine both types of knowledge to regain the inertia already sensed in the early twentieth century. It is therefore an essay on the annulment of the opposition between these two worlds to move towards complementarities of both in a single shared vision. The ultimate goal of this research is to present the development of a critical analysis system for architectural objects that allows differentiation between those who respond to the problems sincerely and those who hide under an agreed appearance, the lack of a method for solving the complexity of the creative present. The research observes three distinct groups of knowledge contained in their respective chapters: The first chapter deals with the Creative Impulse. In it is defined the need to create a framework for the creative individual who, regardless of the current social forces, forebodes that there is something hidden beyond which is still unresolved. We define the "rebel creator" as a kind of person existing throughout history who is able to recognize the changes operating in its present and use them to discover something new and get closer to the origin of creation. At present, this type of character is the one who intuits the existence of a non obviable increasing complexity in society and thought. The second chapter presents some systems, and their properties, for creative performance. It describes the development of a framework composed of current scientific knowledge that architecture has not yet absorbed or reflected directly in her procedures. These are issues of common presence in society but are still reluctant to be included in the creative processes even if they already belong to the collective consciousness. Most of them talk about accuracy, invisible orders, properties of matter and energy, always treated from an objective and apolitical perspective. The ultimate goal pursues the approach and incorporation of these concepts and properties to the sensible world, inextricably unifying all under a single point of view. The last chapter deals with complexity and the ability to reduce it to the essentials. Here we show, as a conclusion, the introduction of several concepts to develop a critical approach to analyzing the architecture of our time. Among them, the concept of Essential Complexity, defined as one that inevitably arises when architecture responds to the increasing stresses that faces today. The thesis maintains the importance of reporting, in the present state of things, the impossibility to respond openly with simplistic solutions and, therefore, the need for solutions to complex character. In this sense, the concept of Underlying Form is defined as a critical tool to evaluate the response of each architecture and possess a critical system to clarify what is an consistent object facing a certain situation. The underlying form is then defined as a way to synchronously understand what we perceive sensitively inseparable from the hidden forces of creative, technological, material and energetic character that support the definition and understanding of any constructed object.

Nowadays, computer simulators are becoming basic tools for education and training in many engineering fields. In the nuclear industry, the role of simulation for training of operators of nuclear power plants is also recognized of the utmost relevance. As an example, the International Atomic Energy Agency sponsors the development of nuclear reactor simulators for education, and arranges the supply of such simulation programs. Aware of this, in 2008 Gas Natural Fenosa, a Spanish gas and electric utility that owns and operate nuclear power plants and promotes university education in the nuclear technology field, provided the Department of Nuclear Engineering of Universidad Politécnica de Madrid with the Interactive Graphic Simulator (IGS) of “José Cabrera” (Zorita) nuclear power plant, an industrial facility whose commercial operation ceased definitively in April 2006. It is a state-of-the-art full-scope real-time simulator that was used for training and qualification of the operators of the plant control room, as well as to understand and analyses the plant dynamics, and to develop, qualify and validate its emergency operating procedures.

Background Gliadins are a major component of gluten proteins but their role in the mixing of dough is not well understood because their contribution to wheat flour functional properties are not as clear as for the glutenin fraction. Methodology/Principal Findings Transgenic lines of bread wheat with γ-gliadins suppressed by RNAi are reported. The effects on the gluten protein composition and on technological properties of flour were analyzed by RP-HPLC, by sodium dodecyl sulfate sedimentation (SDSS) test and by Mixograph analysis. The silencing of γ-gliadins by RNAi in wheat lines results in an increase in content of all other gluten proteins. Despite the gluten proteins compensation, in silico analysis of amino acid content showed no difference in the γ-gliadins silenced lines. The SDSS test and Mixograph parameters were slightly affected by the suppression of γ-gliadins. Conclusions/Significance Therefore, it is concluded that γ-gliadins do not have an essential functional contribution to the bread-making quality of wheat dough, and their role can be replaced by other gluten proteins

Jóvenes Nucleares (Spanish Young Generation in Nuclear, JJNN) is a non-profit organization and a commission of the Spanish Nuclear Society (SNE). The Universidad Politécnica de Madrid (Technical University of Madrid, UPM) is one of the most prestigious technical universities of Spain, and has a very strong curriculum in nuclear engineering training and research. Finishing 2009, JJNN and the UPM started to plan a new and first-of-a-kind Seminar in Nuclear Safety focused on the Advanced Reactors (Generation III, III+ and IV). The scope was to make a general description of the safety in the new reactors, comparing them with the built Generation II reactors from a technical point of view but simple and without the need of strong background in nuclear engineering to try to be interesting for the most number of people possible.

As in each country of Europe with nuclear power, there is a clear gap between those generation that have built the power plants in the eighties and the new generations with less than ten years of experience in the nuclear field. From its creation, Spanish Young Generation in Nuclear (Jóvenes Nucleares) has as an important scope to help transferring the knowledge between those generations in the way that it can be possible. Some years ago, JJNN have started organizing seminars periodically trying to cover as many areas as possible in the nuclear engineering field, and some of them outside the industry but related with it.
