    Diseño conceptual para la elaboración y desalcoholización de cerveza artesanal
    (Universidad EAFIT, 2016) Herrera Alzate, Alejandro; Jaramillo Rodríguez, Alexander; Acosta Maya, Diego Andrés
    Este trabajo de grado consistió en la elaboración y desalcoholización de 3 recetas de cerveza artesanal basadas en recetas previamente diseñadas -- Las cervezas fueron desalcoholizadas mediante un proceso de sublimación bajo vacío y luego reconstituidas con agua carbonatada -- Usando espectrometría infrarroja y cromatografía de gases se determinó que más del 98% del alcohol presente en cada una de las muestras originales fue removido exitosamente -- El grado de aceptación de cada una de las 6 variedades de cerveza se determinó mediante un panel de consumidores -- Los resultados del panel mostraron un mayor grado de aceptación para las cervezas alcohólicas que para las cervezas no alcohólicas y permitieron determinar que existían diferencias significativas entre el sabor de las cervezas no alcohólicas y las cervezas originales -- Por último se elaboró un diseño conceptual de la planta para la elaboración de cerveza con y sin alcohol a partir del cual se realizó un análisis económico en el que se observa que el proyecto no es económicamente viable bajo las condiciones estudiadas, presentando una TIR del 7% y un VPN ($1,054’498,368) menor a la inversión inicial ($1,151’965,681)

    Gestión integral del agua desde una perspectiva de complejidad
    (Universidad EAFIT, 2017) Vásquez Paniagua, José Alfredo; Noguera de Echeverri, Ana Patricia
    In accordance with Mirassou (2009), progress in theoretical definitions that allow to transcend existing and commonly used theoretical and methodological flows that have analysed the problem of water in fragmented form, without considering the multiple interrelations that cover is required; this suggests the need to recognize the nature and complexity of the water by involving other socioeconomic, cultural, governmental, sustainable , ecological and geological concepts, related to those other natural resources involved -- This thesis suggests how starting from a new way of conceiving all phenomena, called concept-time, it is possible to represent them from a complex structure and continuous change (to turn into), and of this way, raise new conceptual alternatives of water management that integrate the multiple relations nature-culture that involve the appropriation of water heritage -- The underlying central assumption in this research considers that a comprehensive water management conceived from the reintegration of nature-culture (which emerge and metamorphose permanently) would make visible the respect for the uniqueness of the biophysical and social contexts (in continuous change), and in turn, would tend to protect the water as heritage in all its manifestations on Earth -- The integration of the relationship between nature-culture, is interpreted as the interaction that takes place within the human being and the environment (biophysical environment), through cultural practices regarding to the different forms of appropriation of water in its different manifestations: use, improvement, care, respect, love and defense -- The contribution of this research focuses on proposing an alternative to address the integral management of water, from a perspective of complexity, that allows to think the phenomena in turning into alternatives -- This new set is based on a change of the usual unidirectional guidance of thinking (which goes from concepts to things), and presents reasoning as a way of a loop or movement of relations in expansion, which continuously go from concepts to things and then to the concepts in turn -- This way of thinking the phenomena in transformation is called shifting thinking, which has support in a new way to conceptualize the phenomena called concept-time -- The shifting thinking emerges from a loop reasoning and poses an investment of the natural belief of human mind, that variability can only be expressed and developed in the invariance -- The shifting thinking permits to conceive the phenomenon of water in continuous change and therefore the integral management of water in transformation
