Publicación Análisis de implementación del CONPES 4086 para la mejora del servicio de acueducto de la población afrocolombiana en Acandí, Chocó (2022-2024)(Universidad EAFIT, 2024) Guerra Muriel, David Alejandro; Pérez Moreno, Hugo Ferney; Amaya Osorio, Lucidia; Amaya Osorio, LucidiaÍtem Characterization and construction of a low-cost electrolyzer(Universidad EAFIT, 2020) Betancur Osorio, Camilo; Sepúlveda García, Yessenia; Builes toro, SantiagoÍtem Diseño conceptual para la elaboración y desalcoholización de cerveza artesanal(Universidad EAFIT, 2016) Herrera Alzate, Alejandro; Jaramillo Rodríguez, Alexander; Acosta Maya, Diego AndrésEste 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)Publicación El agua como herramienta de paz : estrategias para la gestión sostenible del agua como resultado de las iniciativas e instrumentos priorizados en los municipios PDET. Caso de estudio : Núcleo Veredal El Tres, Distrito Portuario de Turbo, Departamento de Antioquia(Universidad EAFIT, 2022) Moreno Velasco, Viviana; Mampaso Cerrillos, Cristina; Gaviria Ríos, Carlos León; Mejía Rivera, OscarThis thesis seeks to identify and define strategic actions that help to turn water a important way to resolve conflicts and convert it into an indispensable tool for building peace in the region of Urabá Antioqueño. It is based on the premise that there can be no peace in any territory if the population does not have access to drinking water, if the aquifers are contaminated or if their use is limited by the territorial control of agents other than state institutions and the communities that inhabit them. And this is the reason why, after the signing of the Havana Peace Accords in 2016, water is highlighted as a structuring and articulating element of the projects identified by the communities to guarantee peace in the territory. But, what does it mean to live in peace? This work establishes a second premise: peace construction cannot be separated from territorial planning and management. Living in peace means guaranteeing living conditions that provide health and hospital resources, economic opportunities, food security and a physical environment free of threats. With this approach, the different instruments, plans and projects for which water is an essential element for the development of the region are considered, and emphasis is placed on the initiatives prioritized in Planes de Desarrollo con Enfoque Territorial (PDET), taking as a case study El Tres, Turbo - Antioquia. This document is composed of four chapters that build a knowledge route around water. The first chapter analyzes the role of water as a tool for the implementation of the Peace Agreements, in the framework of the creation of the PDETs. The second chapter delves into the geographical and historical characterization of the study area and details the different management and planning instruments in order to develop a methodological roadmap to address the multiplicity of actions and intentions that converge in the same territory. The third chapter is a synthesis of the different components that make up the network of strategies for water management, from the environmental, social and institutional perspectives. Finally, the fourth chapter examines six enabling projects of small and large scale framed in six strategic lines. This journey takes us to a new beginning where water becomes the enabling element of the different initiatives and projects prioritized by the communities within the framework of the Peace Agreements and the articulating element of the different instruments operating in the territory. The work seeks, among other things, to show that such an essential element as water is not only a resource, but the key to the development of those communities seeking to build a stable and lasting peace.Ítem Elemental(Universidad EAFIT, 2023) Cárdenas Franco, Luis Alejandro; Vásquez Arias, Mauricio; Colorado Chávez, Paula Andrea; Montoya Estrada, Alejandra; Ospina Lopera, Mónica Liliana; Serna Salazar, Natalia; Universidad EAFITTransmedia project that proposes a tour of the La Volcana stream through the four elements of nature: Earth, Water, Air and Fire. Each element offers a different way to explore, appropriate and experience this water source, providing a unique and multidimensional experience that highlights La Volcana.Ítem ¿Es posible predecir el comportamiento de los precios de los futuros del agua considerando las características estadísticas de sus respectivos índices? : un enfoque desde las redes neuronales(Universidad EAFIT, 2021) Valero Murcia, María José; Bustamante Grajales, María José; Almonacid Hurtado, Paula MaríaThe fear of the scarcity of such an important good as water leads to a debate that consists mainly of two ideas. The first indicates that until now water has been a public good of consumption and a right of all people and, the second indicates that commercializing water will help regulate its price, thus preventing a shortage of this good. In this research report, both opinions are taken into account; however, an emphasis is made on the consequences that would be obtained in the commodities market. The state of California in the United States is taken as a reference, since it has presented high cases of scarcity in recent years and uses the NQH20 index, which shows the price of future water contracts in this state. An analysis is carried out using Neural Networks as it allows us to make inferences that will lead us to anticipate multiple negative consequences that may occur in the future, if the use of this good is not controlled now their scarcity or abundance will cause a huge fluctuation in the price.Publicación Factores que impiden el uso adecuado de los servicios de agua y saneamiento en las comunidades campesinas del ámbito de acción de los proyectos ejecutados por el Fondo Social Las Bambas : estudio de caso de las comunidades Minascucho y Escohorno, región Apurímac, durante el 2015(Universidad EAFIT, 2020) Tairo Quispe, Katherin Patricia; Ojeda Ludeña, Jermani; Vargas Sáenz, Mario EnriqueThis research is a description and explanation of causes those do not allow a good use of water and sanitation services in two Quechua rural communities (Minascucho in Cotabambas province and Escohorno in Grau province) in Apurimac region. Both development projects had done by Las Bambas Social Found Association (FOSBAM) using the economic budget of the Scrow Social Found of Las Bambas (it was given by Xtrata Copper Mining Company in 2004). Both projects have similarities in how they were developed and their results. The execution of them was in 2014 and 2015 and the responsible entity decided to combine two components, social and infrastructure, but the second one was the predominant instead the first one. There had done a qualitative study of case in both communities, getting information of people who received the project, not only in the community, but also in the district where has been implemented the service. This was to know details about factors that caused why people are not using adequately and why they cannot manage by themselves the water and sanitation services. There were used different variables to get appropriate data related to problems that the project wanted to solve. For example, these variables allowed to get data about the project focus, health problems of the people around the area, how they use water and sanitation system, cultural factors related to new services, people habit in water consumption and sanitation, user’s involvement and other entities before, during and after the project execution. This research in social management not only describes which factors are determiners about adequately use of water and sanitation services, but also give a proposal of social marketing in order to contribute to change people habits and attitudes in rural communities in Apurimac, and for this purpose different entities from public, private sector and civil society should work together.Publicación Gestión integral del agua desde una perspectiva de complejidad(Universidad EAFIT, 2017) Vásquez Paniagua, José Alfredo; Noguera de Echeverri, Ana PatriciaIn 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 transformationÍtem Lardi: A trip around La Volcana(Universidad EAFIT, 2023) Cárdenas Franco, Luis Alejandro; Vásquez Arias, Mauricio; Colorado Chávez, Paula Andrea; Montoya Estrada, Alejandra; Ospina Lopera, Mónica Liliana; Serna Salazar, Natalia; Universidad EAFITNarrative and interactive experience starring the squirrel “Lardi”, one of the species that inhabit the environment of the La Volcana stream. Lardi guides the user on a journey through the channel of this water source, inviting them to make decisions about the care, preservation and appropriation of a biodiverse but little recognized and cared for ecosystem.Ítem Microsolvation of dimethylphosphate: A molecular model for the interaction of cell membranes with water(ROYAL SOC CHEMISTRY, 2013-01-01) Ibargueen, Cesar; Manrique-Moreno, Marcela; Hadad, C. Z.; David, Jorge; Restrepo, Albeiro; Universidad EAFIT. Departamento de Ciencias Básicas; Electromagnetismo Aplicado (Gema)We present an exhaustive stochastic search of the quantum conformational spaces of the (CH3O)2PO2 - + nH 2O (n = 1,2,3) systems. We uncover structural, conformational and energetic features of the problem. As in the isolated species, clusters containing the gauche-gauche (gg) conformation of dimethylphosphate (DMP -) are energetically preferred, however, contributions from hydrated gauche-anti (ga) and anti-anti (aa) monomers cannot be neglected because such structures are quite common and because they are close in energy to those containing the gg monomer. At least seven distinct types of O?H-O-H contacts lead to DMP- ? water interactions that are always stabilizing, but not strong enough to induce significant changes in the geometries of either DMP- or water units. Our results lead us to postulate DMP- to be a suitable model to study explicit and detailed aspects of microsolvation of cell membranes.

Water scarcity affect not only one sector or country, but the global population. The sanitation service provider company, Emapa Huaral (Lima), designed and implemented the sanitary and environmental education program. This was analyzed by this investigation, considering a qualitative methodology, and finding strengths and weaknesses; as well as various improvements to make the program an initiative that can be replicated in other areas.Ítem Structural characterization of the (MeSH)4 potential energy surface(SPRINGER, 2013-05-01) Gomez, Sara; Guerra, Doris; David, Jorge; Restrepo, Albeiro; Universidad EAFIT. Departamento de Ciencias Básicas; Electromagnetismo Aplicado (Gema)A random walk on the PES for (MeSH)4 clusters produced 50 structural isomers held together by hydrogenbonding networks according to calculations performed at the B3LYP/6-311++G* * andMP2/6-311++G* * levels. The geometric motifs observed are somewhat similar to those encountered for the methanol tetramer, but the interactions responsible for cluster stabilization are quite different in origin. Cluster stabilization is not related to the number of hydrogen bonds. Two distinct, well-defined types of hydrogen bonds scattered over a wide range of distances are predicted. © Springer-Verlag Berlin Heidelberg 2012.Ítem Structures, energies, and bonding in the water heptamer(AMER INST PHYSICS, 2013-07-28) Acelas, Nancy; Hincapie, Gina; Guerra, Doris; David, Jorge; Restrepo, Albeiro; Universidad EAFIT. Departamento de Ciencias Básicas; Electromagnetismo Aplicado (Gema)In this paper we report the geometries and properties of 38 distinct geometrical motifs located on the B3LYP/6-31+G(d), MP2/6-311++G(d, p) potential energy surfaces of the water heptamer. Binding energies of up to 45 kcal/mol are calculated. All motifs fall within 10 kcal/mol of the most stable conformation, with at least 13 structural patterns located no more than 3 kcal/mol above, leading to a very complex potential energy surface, populated by a multitude of motifs each one allowing large numbers of conformations. Cluster stability does not seem to be correlated with the number of hydrogen bonds. Compact structures are energetically favored by electronic energies with zero-point energy corrections, while more open structures are preferred when temperature and entropy are accounted for. The molecular interactions holding the clusters as discrete units lead to large binding energies but are not strong enough to cause significant changes in the geometries of the interacting monomers. Our results indicate that bonding in the water heptamers can be considered as largely non-shared interactions with contributions from intermediate character of increasing covalency. © 2013 AIP Publishing LLC.Publicación Water, Health and Wellness : The Impact of Treatment Plants on Health Utilization(Universidad EAFIT, 2024) Tangarife Londoño, Katherin; Posso Suárez, Christian Manuel; Gómez Toro, Catalina
