Determinación de propiedades físico-químicas de los materiales agregados en muestra de escombros en la ciudad de Bogotá D. C.

Con la implementación de operaciones unitarias apoyadas en ensayos de laboratorios y evaluando propiedades físico-químicas, se concertó en la necesidad de adoptar estrategias dirigidas a la reducción, reúso y reciclaje de los escombros en la ciudad de Bogotá D. C. Lo anterior permite aumentar la vida útil de los rellenos sanitarios del área, reducir la explotación de los recursos naturales y la indiscriminada disposición en lugares no autorizados. Con una muestra local, este estudio identificó las características como: granulometría; absorción; porosidad; resistencia a la compresión; pH; carbono orgánico total; metales pesados y elementos menores. Resultados de experiencias, nacionales e internacionales, se compararon con esta y se concluyó que los componentes de estos agregados tienen semejanza a los obtenidos de forma natural; ya que poseen alto potencial para ser utilizados en componentes de construcción civil sin función estructural, y cumplen con las especificaciones de las Normas Técnicas Colombianas - NTC.

Technologies for Coal based Hydrogen and Electricity Co-production Power Plants with CO2 Capture

Integrated Gasification Combined Cycle (IGCC) plants allow the combination of the production of hydrogen and electricity because coal gasification process produces a syngas that can be used for the production of both commodities. A hydrogen and electricity power plant has been denominated as HYPOGEN. This report starts by reviewing the basics of the coal gasification process and continues by trying to map all the technological options currently available in the market as well as possible future trends that can be included in a HYPOGEN system . Besides, it offers an overview of the operating conditions and outputs of each process in order to provide the modeller with a useful information tool enabling an easier analysis of compatibilities and implementation of the model.JRC.F.7-Energy systems evaluatio

Stress and sex determination in fish: From brain to Gonads

Fish present remarkable malleability regarding gonadal sex fate. This phenotypic plasticity enables an organism to adapt to changes in the environment by responding with different phenotypes. The gonad and the brain present this extraordinary plasticity. These organs are involved in the response to environmental stressors to direct gonadal fate, inducing sex change or sex reversal in hermaphroditic and gonochoristic fish, respectively. The presence of such molecular and endocrine plasticity gives this group a large repertoire of possibilities against a continuously changing environment, resulting in the highest radiation of reproduction strategies described in vertebrates. In this review, we provide a broad and comparative view of tremendous radiation of sex determination mechanisms to direct gonadal fate. New results have established that the driving mechanism involves early response to environmental stressors by the brain plus high plasticity of gonadal differentiation and androgens as by-products of stress inactivation. In addition to the stress axis, two other major axes – the hypothalamic-pituitary-gonadal axis and the hypothalamic-pituitary-thyroid axis, which are well known for their participation in the regulation of reproduction – have been proposed to reinforce brain-gonadal interrelationships in the fate of the gonad.Fil: Castañeda Cortes, Diana Carolina.

Enhanced Oil Recovery Using Carbon Dioxide in the European Energy System

Enhanced oil recovery using carbon dioxide (CO2-EOR) is a method that can increase oil production beyond what is typically achievable using conventional recovery methods by injecting, and hence storing, carbon dioxide (CO2) in the oil reservoir. This report indicates that the maximum technical potential for increased oil recovery is significant while the CO2 storage capacity is relatively small. A detailed economic analysis suggests that at the oil rpcies of today and with a financial incentive for CO2 storage, a number of CO2-EOR operations could be viable in the North Sea. These projects can contribute to the improvement of the European security of supply by increasing indigenous oil production, and assist in the reduction of GHG emissions and catalyse the development of decarbonised energy conversion technologies by providing the means for safe and permanent storage of CO2.JRC.F.2-Cleaner energie

Digitizing collections: a reflection on negative archive collections, prioritizing procedures and what is lost

A common practice today, for photograph collections, is to create images databases available (or not) on-line. Usually, this is regarded as an added value to the collection, especially for making it available outside its community. This paper focuses on the values that define and prioritize the digitizing process of negative photograph archive collections. A reflection is made on the effects of mass digitization, how are the negatives being represented in their digitized versions and what does this mean for future generations. In this digital age, when the knowledge about historical photographic processes has become the knowledge of experts, the need for complete and comprehensive records is paramount to ensure the passing on of knowledge and, consequently, the preservation of the negative collectionsinfo:eu-repo/semantics/publishedVersio

Retouching the third dimension: the Aurélio da Paz dos Reis stereoscopic negatives archive

The paper explores photography retouching, particularly its use in dry plate stereoscopic negatives. The materials and techniques used and their relationship with the retouching practice in non-stereoscopic photography are discussed. This research focuses on the Portuguese photographer Aurélio da Paz dos Reis's collection of negatives, and how he used retouching for the composition of his stereoscopic portraits. These are studio-like portraits, and today they are a reminder of the artistic society, with whom the photographer had a close relationship and other celebrities. Better known for event and general outdoor photography, this paper presents a contribution to the characterization of a less studied type of photography by this author. Also, these portraits witness the photographic techniques of their time and how the photographic portrait and retouching always had a special place in the history of photography.info:eu-repo/semantics/publishedVersio

Memory recaptured in a small community: preserving retouched photographic negatives, discussing visual culture

This paper focus on a private portrait photographic negatives collection belonging to Foto-Carvalho, a photo-graphic studio of Estremoz (north of Alentejo, Portugal). It explores the techniques, materials, and reasons behind retouching on photographic negatives; also, the validity of retouching in the search for the photographic truth. Studying dry plate photographic negatives from lesser-known collections isa special opportunity to take a closer look to a time and a place. This case study on a Portuguese community will bring new and valued insights to portrait photography and contributions to visual culture of the first half of the 20th century.info:eu-repo/semantics/publishedVersio

Fomentar el gusto por la lectura es una actividad de especial relevancia, ya que los niños deben empezar a establecer el dominio de una lengua materna, en este caso el español, desarrollando competencias lingüísticas como: entender, hablar, leer y escribir textos acordes a la edad en la que se encuentran, esto permite que los niños puedan ir estableciendo de forma correcta una relación apropiada con el idioma español. Teniendo en cuenta estos aspectos, se procedió a diseñar la secuencia didáctica, a partir de un proceso de transversalización en que se involucraron, cuentos de diferentes géneros acordes a la edad de los niños, los DBA y estándares de competencias propuestos por el MEN, y como recurso mediador las tic’s, aprovechando el interés que en la actualidad este recurso despierta en los niños, y de esta forma demostrar y capacitar que el aprendizaje mediado por las tic’s puede obtener resultados exitosos en cuento al aprendizaje que se busca alcanzar en los niños. Uno de los retos de la educación en la actualidad es la de involucrar de forma adecuada los avances que la globalización día a día nos ofrece, en este caso los recursos tecnológicos, para fomentar estrategias de enseñanza, motivación y aprendizaje en los niños, el llamado que como docente tenemos es el de mantenernos a la vanguardia de los procesos innovadores en el desarrollo de nuestra labor.The following work is presented as a requirement to opt for a degree in child pedagogy, a program offered by the Open and Distance University UNAD, through the development of a process in which a didactic sequence designed to generate a strategy that promotes learning was implemented. A taste for reading in the children of the first grade of the Moderno Discovery People school, an educational institution that is located in the municipality of San Alberto Cesar. Fostering a taste for reading is a particularly relevant activity, since children must begin to establish mastery of a mother tongue, in this case Spanish, developing linguistic skills such as: understanding, speaking, reading and writing texts according to the age in which they are, this allows children to be able to correctly establish an appropriate relationship with the Spanish language. Taking these aspects into account, we proceeded to design the didactic sequence, based on a mainstreaming process in which stories of different genres were involved according to the age of the children, the DBAs and competency standards proposed by the MEN, and tic's as a mediating resource, taking advantage of the interest that this resource currently arouses in children, and in this way demonstrate and train that learning mediated by tic's can obtain successful results in terms of the learning that is sought to be achieved in children. One of the challenges of education today is to adequately involve the advances that globalization offers us every day, in this case technological resources, to promote teaching, motivation and learning strategies in children, the so-called that as a teacher we have is to stay at the forefront of innovative processes in the development of our work
