Ítem Evaluation of low-cost alternatives for water purification in the stilt house villages of Santa Marta's Ciénaga Grande(Elsevier, 2020-01) Lugo Arias, José; Burgos Vergara, Javier; Lugo Arias, Elkyn; Gould, Audrey; Ovallos Gazabon, DavidWater purification is indispensable to guarantee safe human consumption and to prevent diseases caused by the ingestion of contaminated water. This requires a series of water treatment processes which require investment. However, the economic limitations of rural communities hinder their ability to implement such water-treatment systems, as is the case in Ci enaga Grande of Santa Marta (“Large Swamp”, in English) in Colombia. Low-cost systems can be used instead as simple and safe alternatives. Therefore, the objective of this work was to evaluate non-conventional, low-cost water processes to purify the water from the collection point of two stilt house villages in Ci enaga Grande of Santa Marta. These include: 1) Using two natural coagulants, Moringa Oleifera and Cassia Fistula; 2) filtration through a biosand filter and a carbon activated filter; and 3) disinfection through UV-C Radiation and through solar disinfection. The results showed a turbidity values reduction between 52% and 96% using the two natural coagulants; both turbidity and total coliforms achieved reductions of 98.4% and 76.9%, respectively in the filtration process; and removal of total coliforms up to 98.8% in the disinfection process. Despite the high rates of reduction in the different parameters, the water does not comply with the recommended limits for safe drinking water.Ítem Liderazgo: tendencias emergentes para inspirar la gestión de personas en las organizaciones(Ediciones Universidad Simón Bolívar, 2018) Prieto Pulido, Ronald; García Guiliany, Jesús; Rincón Quintero, Yanyn; Lechuga Cardozo, Jorge; Leyva-Cordero, Oswaldo; Cazallo-Antúnez, Ana María; Paz, Ubertino; Paz Marcano, Annherys; Cantillo Campo, Nair; González Godoy, Dálice; González Morillo, Leandro; Suárez Barros, Horacio; Hennesy Noguera, Germán; Ruz Gómez, Alexander; Lobo Muñoz, Deyanira; Pirela Morán, William; Quijada Oquendo, Gisela; Ovallos Gazabón, David; Landazury Villalba, Luis Fernando; Lugo Arias, Elkyn; Redondo Salas, Alberto; Ethel Durán, Sonia; Parra, Márgel Alejandra; Araque B., Francis; Aldana Rivera, Edna; Gil Osorio, Ivón; Carrero González, Carmen; Orostegui Santander, María; Cardeño Portela, Edwin; Ramírez Cardeño, WendyEl libro Liderazgo: tendencias emergentes para inspirar la gestión de personas en las organizaciones presenta observaciones de mucho interés académico sobre este importante campo del management, se destaca el estudio realizado usando herramientas de minería de datos a partir de la base Scopus sobre la relación entre innovación y competitividad. Se destacan de la misma manera que todos los capítulos que componen la obra hacen un esfuerzo por una mayor interpretación de los conceptos revisados en su marco teórico, desde una perspectiva más crítica. Los resultados entregados en cada uno de los capítulos son valiosos aportes empíricos en su mayoría desde la perspectiva inductiva.
