    Desde la Constitución política de 1991, en Colombia, se reconoce legalmente la libertad religiosa, abriendo el espectro de prácticas y experiencias a un abanico mayor que el precedente, limitado al culto católico. Aunque Bogotá, la ciudad capital, ha mostrado una tendencia histórica a permanecer bajo un marco de referencia religioso eminentemente católico, la apertura no ha sido ajena a este territorio. Es por ello relevante conocer, treinta años después, el mapa de desarrollo de prácticas religiosas plurales y diferentes a la hegemónica tradición católica, haciendo hincapié en el análisis de las religiones orientales. En este estudio, se llevó a cabo una investigación cualitativa de tipo exploratorio-descriptiva al objeto de poder analizar el progreso de la implantación del pluralismo religioso en Bogotá observando el comportamiento de las religiones orientales. Los resultados obtenidos confirman que, a pesar del avance en libertad religiosa, en Bogotá la implantación de espacios de culto asociados a religiones orientales es escaso, debido no solamente a la competencia generada por un catolicismo dominante y un evangelismo en ascenso, sino también por la emergencia del ateísmo y de experiencias de religiosidad amparadas en el marco de la “new age” o nuevas espiritualidades que absorben en gran medida su lenguaje, prácticas y objetos de culto favoreciendo su desdibujamiento y relegándolas a un espacio de influencia limitado.Since the Political Constitution of 1991, in Colombia, religious freedom is legally recognized, opening the spectrum of practices and experiences to a greater range than the previous one, limited to Catholic worship. Although Bogotá, the capital city, has shown a historical tendency to remain under an eminently Catholic religious framework, the opening has not been foreign to this territory. It is therefore relevant to know, thirty years later, the development map of plural religious practices different from the hegemonic Catholic tradition, emphasizing the analysis of Eastern religions. In this study, an exploratory-descriptive qualitative research was carried out in order to analyze the progress of the implementation of religious pluralism in Bogotá by observing the behavior of Eastern religions. The results obtained confirm that, despite the advance in religious freedom, in Bogotá the implementation of places of worship associated with Eastern religions is scarce, due not only to the competition generated by a dominant Catholicism and a rising evangelism, but also by the emergence of atheism and experiences of religiosity protected in the framework of the "new age" or new spiritualities that largely absorb their language, practices and objects of worship favoring their blurring and relegating them to a limited space of influence

    Experiencias de profesores en su quehacer en los distintos ambientes de aprendizaje presenciales y a distancia.Para el Centro de Excelencia Docente aeiou constituye un honor presentar la publicación del Tercer Encuentro de Prácticas Pedagógicas Innovadoras en el que se destacan cuarenta trabajos de profesores de UNIMINUTO provenientes de diferentes sedes. Con este encuentro son ya tres que bajo la dirección de aeiou los profesores han compartido su quehacer en los distintos ambientes de aprendizaje presenciales y a distancia. Cada año el Centro de Excelencia Docente invita a los profesores a participar en este evento, para el 2108 además de la inscripción voluntaria por parte de cada profesor, se invitó al estudiantado a que postularan a sus profesores que consideraban eran innovadores y creativos en el cumplimiento de su función docente y se obtuvo una respuesta importante por parte de los estudiantes, que para algunos profesores resultó sorpresiva porque quizás no habían considerado que el trabajo que hacían en su ambiente de aprendizaje era diferente, fuera de lo común. Luego de una evaluación de jurados nacionales e internacionales de las prácticas presentadas y de la realización del evento, que tuvo como novedad hacerlo de forma simultánea en cuatro sedes donde UNIMINUTO tiene presencia: Buga, Ibagué, Pereira y Bogotá, se comparte la presente publicación para tener como referencia y evidencia el trabajo que los profesores hacen a diario

    Neutral pathways and heat flux widths in vertical- and horizontal-target EDGE2D-EIRENE simulations of JET

    Get PDF
    This paper further analyses the EDGE2D-EIRENE simulations presented by Chankin et al (2017 Nucl. Mater. Energy 12 273), of L-mode JET plasmas in vertical-vertical (VV) and Vertical-horizontal (VH) divertor configurations. As expected, the simulated outer divertor ionisation source peaks near the separatrix in VV and radially further out in VH. We identify the reflections of recycled neutrals from lower divertor tiles as the primary mechanism by which ionisation is concentrated on the outer divertor separatrix in the VV configuration. These lower tile reflection pathways (of neutrals from the outer divertor, and to an even greater extent from the inner divertor) dominate the outer divertor separatrix ionisation. In contrast, the lower-tile-reflection pathways are much weaker in the VH simulation and its outer divertor ionisation is dominated by neutrals which do not reflect from any surfaces. Interestingly, these differences in neutral pathways give rise to strong differences in the heat flux density width λq at the outer divertor entrance: λq = 3.2 mm in VH compared to λq = 11.8 mm in VV. In VH, a narrow channel exists in the near scrape-off-layer (SOL) where the convected heat flux, driven by strong Er × B flow and thermoelectric current, dominates over the conducted heat flux. The width of this channel sets λq and is determined by the radial distance between the separatrix and the ionisation peak in the outer divertor

    Investigation into the formation of the scrape-off layer density shoulder in JET ITER-like wall L-mode and H-mode plasmas

    The low temperature boundary layer plasma (Scrape-Off-Layer or SOL) between the hot core and the surrounding vessel determines the level of power-loading, erosion and implantation of material surfaces, and thus the viability of tokamak-based fusion as an energy source. This study explores mechanisms affecting the formation of flattened density profiles, so-called ‘density shoulders’, in the low-field side (LFS) SOL, which modify ion and neutral fluxes to surfaces – and subsequent erosion. There is evidence against local enhancement of ionization inducing shoulder formation. We find that increases in SOL parallel resistivity, Λdiv (=[L||νei Ωi ]/cs Ωe), postulated to lead to shoulder growth through changes in SOL turbulence characteristics, correlates with increases in upstream SOL shoulder amplitude, As only under a subset of conditions (D2-fuelled L-mode density scans with outer strike point on the horizontal target). Λdiv fails to correlate with As for cases of N2 seeding or during sweeping of the strike point across the horizontal target. The limited correlation of Λdiv with As was also found for H-mode discharges. Thus, while Λdiv above a threshold of ~1 may be necessary for shoulder formation and/or growth, another shoulder mechanism is required. More significantly we find that in contrast to parallel resistivity, outer divertor recycling as quantified by the total outer divertor Balmer Dα emission, I-Dα, does scale with shoulder amplitude where Λdiv does and even where Λdiv fails. Divertor recycling could lead to SOL density shoulder formation through: a) reducing the parallel to the field flow (loss) of ions out of the SOL to the divertor; and b) changes in radial electric fields which lead to ExB poloidal flows as well as potentially affecting the SOL turbulence birth characteristics. Thus changes in divertor recycling may be the sole process in bringing about SOL density shoulders or in tandem with parallel resistivity
