    Hacia la construcción de un modelo de simulación de la transmisión del dengue en Colombia

    Dengue fever has been considered a public health problem worldwide. In several Colombian regions, where environmental conditions seem to be favorable enough for disease transmission, incidence has been showing important high values. Simplified versions of the infectious disease mathematical models CIMSiM and DENSiM were proposed to be applied for representing the transmission dynamics of dengue incidence in a specific Colombian locality. This is our first quantitative attempt to explore the possible influence of climatic variables on dengue transmission in endemic urban areas. Climatic records were analyzed to detect possible anomalies and their degree of association with epidemiological time series.

    Modelamiento estocástico en la determinación de la oferta hídrica del río Source Matelas (Haití): aplicación al predimensionamiento de un embalse

    Source Matelas, located in the West State, Republic of Haiti, is a town with scarce economical resources and low quality of life, mainly because of the absence almost total of water. In this work we give a first approximation to a water reservoir pre-feasibility study, related to water supply quantification of the region, by means of hydrological methods to estimate unknown information. Long term components of the hydrological balance are calculated and daily mean yield that serves the model of reservoir simulation is estimated. The mean runoff calculated for the Source Matelas River is 0.026 m3/s. Based on reservoir modeling, volume needed to supply different percentages of the mean runoff is calculated. Therefore, it can be seen that population water demand will be supplied totally if a reservoir of 212000 m3 volume is constructed.
