Eficiencia energética y regulación económica en los servicios de agua potable y alcantarillado

Este documento analiza el consumo de energía en el sector de agua potable y alcantarillado y propone políticas regulatorias para mejorar la eficiencia energética de los prestadores de estos servicios en América Latina y el Caribe. Está dirigido a las agencias de regulación sectorial, así como todas las demás partes interesadas del sector privado y público.

Análisis, prevención y resolución de conflictos por el agua en América Latina y el Caribe

Los conflictos de agua se han incrementrado considerablemente en los últimos años hasta alcanzar altos niveles de complejidad e impacto en las economías, los ámbitos políticos, la estabilidad social, las poblaciones y el ambiente. Este trabajo busca proveer un marco conceptual para el análisis de estos conflictos

O hibridismo textual em como agua para chocolate (1989), de Laura Esquivel: folhetim, almanaque, caderno de receitas e diário íntimo

Este artigo pretende discutir como se articulam, na estrutura híbrida do romance Como agua para chocolate, alguns gêneros textuais discursivos comumente dedicados à leitura de mulheres – folhetim, almanaque, caderno de receitas e diário íntimo –, cuja presença fica sugerida desde o subtítulo “novela de entregas mensuales, con recetas, amores y remedios caseros”. Esses gêneros se misturam na construção da narrativa, possibilitando, no âmbito da pós-modernidade, uma leitura crítica do papel da mulher na sociedade patriarcal da primeira metade do século XX.

Contaminación microbiana en las líneas de agua de las unidades odontológicas

Introduction and Objective: Microorganisms are responsible for multiple infections and pathologies; this is why it is important to control microbes that can be found in the triple syringe used for irrigation in different dental procedures. The aim of this study was to identify cultivable species of microbes (fungus and bacteria) found in some dental units water lines of a private dental clinic from Medellín, Colombia. Materials and Methods: Random samples were taken from 11 chairs from a total of 89; a sample of water of 500ml was collected from the triple syringe of each selected chair. The study aim to search for the presence of total coliforms, filamentous fungi and leavened Results: the average presence of microorganisms was between 40CFU and more of 200 CFU. Microorganisms such as Aeromona salmonicida, Actinobacilus sp and Pseudomona maltophil were isolated. No total coliforms neither fecal coliforms were found. Conclusions: the high levels of contamination suggest that there is a mature biofilm in somewhere of the dental unit water line, but the absence of total and fecalis coliforms suggest that the water had been treated.

Capacidad de uso de la tierra en la cuenca de la Corriente del Lobo, Itatinga, São Paulo, Brasil

The objective of the research was to define the classes of use capacity of 2403.25 ha in the basin of the Corriente del Lobo - Itatinga (SP), (22°03'56" to 22°59'12" of latitude S and 48°38'47" to 48°41'25" of longitude W Gr.). The soil use capacity was obtained by using the SIG IDRISI 32 crossing the documents of steepness and soils and the document of judgment of classes of soil use capacity and of the utilitarian rising of the physical milieu. The classes and subclasses areas of use capacity presented the following values: IIIa - 68.60 ha (2.85%), IIIe,s - 1919.15 ha (79.86%); IIIe - 210.60 ha (8.76%); IVe - 3.38ha (0.14%); IVe,s - 157.42 ha (6.55%) and VIe,s - 44.10 ha (1.84%). The lands of the basin were distributed in three classes (III, IV and VI) and six subclasses but the biggest extension (79.9%) belonged to the subclass IIIe,s. The modules of the IDRISI allowed to discriminate, mapping and to quantify quickly the soil use capacity of the areas of classes and subclasses in the basin.

Geoprocessamento de variáveis morfométricas para caracterização da microbacia do Córrego do Petiço

This study aims to perform the morphometric characterization of the watershed stream Petiço, Botucatu-SP, through techniques of GIS by GIS IDRISI Selva and Charter planialtimetric Botucatu (SF-22-ZB-VI-3) , edited by IBGE (1969), scale 1: 50000 for ranking the drainage network and the morphometric analysis. The variables analyzed were the dimensions, the relief pattern, pattern of the drainage network and the shape variables. The results show that related to how the watershed has an oblong shape with environmental interpretation with low tendency to flooding and erosion. The sinuosity index of 1.22 shows that the channels of the micro tend to be somewhat sinuous, which allows to infer that is permeable soil with good water infiltration. Based on the results of the morphometric variables was found that the watershed is in good condition of conservation, however, presents certain risks of susceptibility to erosion, and environmental degradation in some points, being fundamental to the maintenance of vegetation cover, in view of the roughness coefficient (Rn). Thus, the evaluation of morphometric characteristics in the study watershed constitutes an important tool in conjunction with the use of GIS and Geographic Information Systems makes possible the planning and management of natural resources aimed at their conservation.
