    Treated water represents a real alternative to reduce the global freshwater crisis However management approaches are applied that depart from the linear thinking of producing consuming and discarding In this sense the circular economy is an option to generate products that from their origin are oriented to be reused In this way if we think about treated water from this conceptual framework we would mitigate water scarcity in cities The effluent generated in the Las Joyas Wastewater Treatment Plant was evaluated in the survival development and cultivation of Oreochromis niloticus 350 adult tilapia specimens were sown 50 females and 300 males The effluent will achieve the survival development and cultivation of tilapi

    Los niños sordos se comunican predominantemente en lenguaje de señas, mientras que los niños con dificultades auditivas se comunican predominantemente en lenguaje oral. Las relaciones que estableces en el entorno educativo para los estudiantes sordos, tanto en los aspectos educativos como en el reconocimiento de la lengua de signos, resaltan la realidad específica existente sobre la atención a la diversidad y la igualdad de oportunidades. En este ensayo se analiza especialmente el papel del manejo de una lengua de señas en la adquisición del lenguaje escrito en las personas sordas, considerando algunos planteamientos respecto a la posibilidad de transferencia de las habilidades lingüísticas

    Passenger Exposure to Magnetic Fields due to the Batteries of an Electric Vehicle

    Full text link
    In electric vehicles, passengers sit very close to an electric system of significant power. The high currents achieved in these vehicles mean that the passengers could be exposed to significant magnetic fields. One of the electric devices present in the power train are the batteries. In this paper, a methodology to evaluate the magnetic field created by these batteries is presented. First, the magnetic field generated by a single battery is analyzed using finite elements simulations. Results are compared to laboratory measurements, taken from a real battery, in order to validate the model. After this, the magnetic field created by a complete battery pack is estimated and results are discussed

    Primary school students, from 1st to 5th grade, of the educational institutions of the municipality of Puerto Boyacá have been presenting low levels of performance in the segment of textual production, accompanied by the inappropriate use of the integral elements that give the text. Such a denominator, the basic rights of learning regarding writing has not been consolidated. Therefore, the main objective is to develop authentic writing processes with primary school children based on the reconstruction and compilation of interculturality and the oral tradition of Puerto Boyacá and, based on this, have a qualitative approach, participative and interpretive action research; under which the dynamic and symbolic nature of the context is addressed. The investigative result, highlighting the reflection that this article of the course of the doctoral thesis that is developed, is expected to correspond to those proposed from the objectives and the methodology, aligned to counteract the problem.Los estudiantes de básica primaria, de 1° a 5° de las instituciones educativas del municipio de Puerto Boyacá han venido presentando bajos niveles de desempeño en el segmento de producción textual, acompañado por demás de la inadecuada utilización de los elementos integrales que dan al texto tal denominador, los derechos básicos de aprendizajes respecto de la escritura no se ha consolidado. Por lo tanto, se tiene como objetivo fundante desarrollar procesos de escritura auténtica con niños de educación básica primaria a partir de la reconstrucción y recopilación de la interculturalidad y la tradición oral de Puerto Boyacá y, con base en esto, disponer de un enfoque cualitativo, investigación acción participativo y de corte interpretativo; bajo el cual se abordan la naturaleza dinámica y simbólica del contexto. El resultado investigativo, resaltando la reflexión que pretende este artículo del curso de la tesis doctoral que se desarrolla, se espera sean correspondientes a los planteados desde los objetivos y la metodología, alineados en contrarrestar la problemática.   &nbsp

    Multi-temporal unmixing analysis of Hyperion images over the Guanica Dry Forest

    Get PDF
    This paper presents a methodology to analyze time-series data from Hyperion to study seasonal vegetation dynamics on the Guánica Dry Forest in Puerto Rico. Unmixing analysis is performed over ten near-cloud-free Hyperion images collected in different months in 2008. Abundance maps and endmembers estimated from the unmixing procedure are used to analyze the seasonal changes in the forest. Results from the analysis are compared with published knowledge of the Guanica Forest phenology
