14. Generation of Photovoltaic Solar Energy. Evaluation of the Demand Curve with the Insert of Grid-connected Photovoltaic Power System at CINDACTA II, Curitiba-PR, Brazil.
ABSTRACT Unlike some countries, Brazil has a predominantly hydraulic energy matrix, a clean and renewable source. But, in recent years, both the non-renewal of the normal volumes of water in the reservoirs and the lack of consciousness in the consumption of water and energy have placed the country in a critical state of energy supply leading to many intensiv

15. A multi-criteria decision making approach to balance water supply-demand strategies in water supply systems
Abstract Paper aims this paper proposes a model to aid a group of decision makers to establish a portfolio of feasible actions (alternatives) that are able to balance water supply-demand strategies. Originality Long periods of water shortages cause problems in semi-arid region of northeast Brazil, which affects different sectors such as food, public health

16. Effects of changes in the riparian forest on the butterfly community (Insecta: Lepidoptera) in Cerrado areas
ABSTRACT Preserved riparian vegetation usually has greater environmental complexity than the riparian vegetation modified by human actions. These systems may have a greater availability and diversity of food resources for the species. Our objective was to evaluate the effect of changes on the structure of the riparian forest on species richness, beta diversi

17. Successive Cultivation of Soybean/Corn Intercropped with Urochloa brizantha topdressed with Nitrogen
ABSTRACT Corn intercropped with Urochloa brizantha (Syn, Brachiaria brizantha) has been indicated as a suitable alternative management practice for rational land use in crop-livestock production systems in the Cerrado region of Brazil. An experiment was carried out in Maracaju, MS, Brazil to evaluate the effect of sequences of soybean/second-crop corn system

18. Seasonality of soil water exchange in the soybean growing season in southern Brazil
The processes of water transfer in the soil-plant-atmosphere system are strongly affected by soil use and management. Differences in the dynamics of soil water transfer between no-tillage (NT) and conventional tillage (CT) practices during a soybean (Glycine max) growing season in southern Brazil were assessed in this study. All the water balance components

20. Water fluoridation in 40 Brazilian cities: 7 year analysis
Objectives Fluoride levels in the public water supplies of 40 Brazilian cities were analyzed and classified on the basis of risk/benefit balance. Material and Methods Samples were collected monthly over a seven-year period from three sites for each water supply source. The samples were analyzed in duplicate in the laboratory of the Center for Research in P

21. Programa de simulação de sistemas de aquecimento Solar. / A software for simulation of solar heating systems.
This paper presents the development of a software that simulates the thermal performance of a solar water heating system with forced circulation, suitable for buildings. The implemented model computes the mass and energy balance in the thermal tank every hour. Its input data are values from a typical meteorological year of a chosen location and the hot water

22. Desenvolvimento de um controlador de irrigação para áreas experimentais / Development of an irrigation controller for experimental areas
Irrigation scheduling at experimental areas is determined by several factors, which are mainly related to features of each unit (container or bed) and criteria set by researchers. Many times the experimental areas are greenhouses and depending on the research may be necessary provide mechanisms for monitoring sensors and controlling actuators on each unit in

24. Aspectos da biogeoquímica dos rios Teles Pires e Cristalino - MT / Aspects of the biogeochemistry of Teles Pires and Cristalino rivers - MT
The Amazon basin occupies around 40% of the brazilian territory and contains more than 60% of the water resources of the country. Abundant and yet little exploited region water resources constitute a national treasure to which the nation can not turn its back. Besides changes in land use/cover, several hydroelectrical plants are planned for rivers in the reg
