Community participation and communication processes in the implementation of programs of resettlement of families within the context of urban development in the city of Barranquilla (Colombia)

Abstract: Planning processes of development and growth of the city of Barranquilla have required the relocation of the population living in areas of intervention actions. Under the current Land Use Plan of Barranquilla (POT) (1), the urban development project "La Loma" includes, among other activities, the transfer of a large number of people currently living in this area. For this reason, this article aims to review the current POT and other legal documents related to the Plan in order to identify and analyze the community participation component. The results of the documents revealed the presence of regulatory elements associated with community participation. The results also showed potentially useful spaces for the implementation of inclusive communication processes. Therefore, this article proposes a guide for the formulation of a strategic communication plan with a focus on participatory communication and dialogue facilitator to be used during the execution of urban projects that include the relocation of families.

Aproximación al diseño de robots paralelos, análisis de caso del robot delta

Abstract: Los robots paralelos tienen una arquitectura cinematica cerrada, en la cual se obtienen multiples caminos que unen dos puntos del mecanismo, permitiendo mayores velocidades en el espacio de trabajo, una mayor rigidez estructural y por ende muy altas aceleraciones frente a los robots de cadenas cinematicas abiertas. Este articulo presenta el estudio para el diseno de un robot paralelo de 4 grados de libertad delta 3T1R (3 traslacional y 1 Rotacional); se definen los requerimientos de diseno de acuerdo al estudio hecho en el benchmarking, procediendo con obtener en modelo cinematico inverso mediante la terna de angulos a partir de una posicion de la base movil, llegando a resolver la ecuacion vectorial del punto central de la plataforma fija; para determinar la cinematica directa se determinan las posiciones del punto central de la plataforma movil, solucion que esta supeditada a la interseccion de tres esferas formada por cada brazo.

La sostenibilidad en el diseño de cadenas de suministro de biocombustibles

Abstract: The challenge of using renewable energy sources means that the produc­tion of biofuels and the design of their supply chains, should be pursue environmental and social benefits beyond the purely economic benefit. In this paper are revised some discussions about the impact of biofuels on sustainability and researching in the biofuel supply chains design of first and second generation via mathematical optimization, to analyze how environmental and social concerns have been considered in this problem. Finally, techniques most used optimization were identified and the review found that the concept of sustainability in the design of biofuel supply chains through modeling, is just beginning.

Identificación de bacterias resistentes a di-bromo-mercurio aisladas de sedimentos en playas de Cartagena de Indias, caribe colombiano

Abstract: This study identified di bromo-resistant bacteriain marine sediments mercury isolated beaches ofCartagena de Indias, Colombia, by the isolation,purification and preservation of marine bacteria resistantto antibiotics, microscopic and biochemicalidentification, susceptibility test di-bromo-mercury.The development of this study is to monitor theexecution of the presence of bacteria resistant toantibiotics and mercury compounds and / or theirresistance genes in the environment associated withenvironmental toxins and the origin of the sourceof pollution generated by the resistance.

Evaluating the Influence of Camera and Projector Lens Distortion in 3D Reconstruction Quality for Fringe Projection Profilometry

Abstract: We study the influence of geometric distortions of the camera and projector lenses on 3D reconstruction quality for fringe projection profilometry. Experimental results on real objects and their 3D models show the accuracy is improved.
