    Diseño y caracterización de una bobina de tesla para ionizar plasma
    Muñoz Ramirez, Uriel; Vásquez Beltran, Cristhian Camilo; Hincapié Campos, Williams Steve; Carrillo Álvarez, Víctor Manuel, Co-director
    En este artículo investigativo se logró caracterizar una bobina Tesla, un dispositivo que utiliza un circuito RLC con una frecuencia resonante. La caracterización se realizó con cálculosteóricos, experimentos prácticos y simulaciones del circuito. En la etapa práctica, se generó plasma a temperatura ambiente, lo que permitió observar directamente los efectos de la resonancia en el dispositivo. Además, se obtuvieron resultados sobre la frecuencia de resonancia de los circuitos implicados. Con la información teórica, se realizó una simulación en una plataforma en línea, que permitió visualizar el comportamiento de las frecuencias de resonancia en diferentes condiciones. Esta simulación permitió un análisis comparativo entre los resultados teóricos y prácticos, evaluando la resonancia y caracterización de la bobina en relación con las propiedades de cada componente. El análisis comparativo reveló coherencia entre los datos teóricos y prácticos, sin embargo, se observó que la inducción no era eficiente por la diferencia entre las frecuencias de resonancia entre los circuitos primario y secundario.

    Escalante Niño, Carlos Fernando; Villalba, Jorge Armando
    The management of working fluids in industries such as hydrocarbons, water treatments, oil production, refineries and among others, is a task that involves the design, calculation and construction of complex pipeline networks with control and instrumentation elements. integrated that seek to give security and meaning to the process itself. The selection of these components starts from the idea of controlling the multiple variables of these fluids in motion from the effective interaction of these elements and the functional compression of them. However, the marked diversification of these elements leads to the design and budget of a project specific problems that range from the cost of a very varied stock of valves, spare parts and parts, to the factory restrictions that a valve has by construction and limit the range of its applicability. Thinking about how to minimize these problems in a practical and viable way, this thesis develops a multifunctional valve model that integrates 3 typical models of different operation into one, considering and attending to the regulatory guidelines for these equipment and real border conditions on the which these valves work on. In the first stay of this document, a conceptual environment was considered, which alludes to basic concepts of theory and calculation that allow us to understand the basis of the design and conception of the proposed model in its aspects of operation and physical form. Later, the valve design was developed in a CAD work environment, supported by the formulation of calculations and selection of materials for certain base components of the model, as well as the reference to technical parameters that are necessary to understand in order to make logical sense of certain internal valve systems and their effective selection. The simulation and validation of the model is made from specific tests of static pressure, by dynamic regime, vorticity in the CAE-CFD work environment, from which the results obtained were analyzed and the feasibility of the internal geometry and the reliability of the design concepts formulated in the previous part of the document. Similarly, the evaluation of these results allowed inferring elements of judgment in the valve operation recommendations and their comparison with commercial models of the same level. Finally, a commercial evaluation of the model was carried out in order to estimate economic costs as well as its technical feasibility

    Memory Game: del azar a la concentración
    Muñoz Sánchez, Adriana; Batista Escobar, Orlando; Rengifo Guerrero, Elizabeth
    This is a methodological proposal that is based on the concept of the game to develop with students from third to fifth grade of primary school of the Leticia educational institution in the city of Monteria concentration and logic skills, as well as the learning of vocabularies of the statistics and geometry subjects. Starting from the fact that students' learning is strictly linked to their motivation and comprehension capacity, in addition to the use of an increasingly enriched vocabulary that allows them to feel comfortable and confident to develop exercises inside and outside the classroom of class. In particular, students from grades three to five at the Leticia educational institution in the city of Monteria have shown difficulty in developing statistical logic skills and learning vocabulary in both statistics and geometry. Limiting himself to writing the explanations that the teacher provides, to record information on the board or in the text, without any type of cognitive stimulus that allows a construction of numerical thinking, thus showing difficulty in the analysis and interpretation of data, statistical tables, geometric formulas among other evidence of learning. Therefore, this work constitutes a teaching-learning proposal for the mathematics teacher (geometry, statistics, arithmetic) to work with their students, based on the game, since this is a way in which the student become more engaged with their learning process
