1. TECHNICAL AND ECONOMIC FEASIBILITY OF USING A VARIABLE-FREQUENCY DRIVE IN MICRO-IRRIGATION SYSTEMS
ABSTRACT Irrigation is essential for the development of crops in regions with scarcity or irregular rainfall distribution, enabling high productivity. However, the use of water resources and electrical energy leads to a concern with irrigation efficiency. Pressure demand varies during the operations of irrigation systems and the appropriate pressure can be r

2. 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

4. Águas pluviais para usos não potáveis em escolas municipais: estudo de caso na região da baixada de Jacarepaguá, RJ. / Rainwater for non potable uses in municipal schools: study of case in the region of Baixada de Jacarepaguá- RJ.
Rainwater harvesting does not constitute a new strategy or technology. However, recently it has been proposed in well-developed regions or in development (peri-urban) in response to long periods of dryness, increased demand for water, greater public awareness of urban flooding and its genesis, and increased interest in sustainable construction practices, inc

5. Estudo de viabilidade do sistema de ancoragem de uma unidade flutuante de produção e armazenamento \"FPSO\" acoplada a um sistema de completação seca \"TLWP\". / Mooring system feasibility study of a floating production and storage unit \"FPSO\" coupled to a dry tree system \"TLWP\".
The oil and gas production in Brazilian fields are commonly found in deep water and situated far away from the coast, reaching distances of more than 100 km as, for example, in the Campos Basin or Santos Basin. Due to the heavy oil and lack of pipeline infrastructure found in these fields, not only subsea equipments that must support high pressure but also l

6. Acumulação de nutrientes e metais pesados em solo, água e hortaliças em áreas cultivadas com olerícolas no Agreste de Pernambuco. / Accumulation of nutrients and heavy metals in soil, water and fruits in areas cultivated with vegetables in the Agretes region of Pernambuco state.
Increasing world population elevates the demand for food. Then, it s a constant challenge to ensure food with quantity and quality appropriate. The management of soil fertility using fertilizers and controlling pests and weeds are necessary strategies for maintaining or increasing agricultural production. Agrochemicals are anthropogenic sources potentially p

7. Previsão de demanda para sistema de abastecimento de água / Water demand prediction for water distribution system
The present work focuses the problem of water demand forecasting for real time operation of WSS. The study was conducted using hourly consumption data from water distribution system from the cities of São Carlos, Araraquara, SP, to identify the model that fits better. It were studied the artificial neural network Multilayer Perceptron (ANN MLP), the Dynamic

8. Sistema integrado de informações para preservação de recursos hídricos em unidades de conservação / Integrated information system for protecting water resources in protected areas.
The increasing demand of mankind by use of water quality and sufficient volume to meet their needs in their different uses, shows that water resources must be managed and preserved. A watershed is the physical unit that integrates the entire flow of water that makes up the hydrological cycle, but its use is being carried out in a disorderly way, without comp

11. Micronutrientes e metais pesados tóxicos: do fertilizante ao produto agrícola / Micronutrients and toxic heavy metals: from fertilizer to agricultural product
The presence of toxic heavy metals in fertilizers has been a big concern. It has been indicated as one of the obstacles to sustainable food production. On the other hand, there is a growing demand for better-quality products, with high micronutrient content and low malnutrition factors, such as toxic heavy metals. In Brazil there are scarce number of studies

12. Characterization and treatment of sludge originated from septic tanks / Caracterização e pré-tratamento de lodo de fossas e de tanques sépticos
Septic tanks are small structures used for partial treatment of wastewater produced from urban and rural areas. It utilization is justify mainly by simplicity of construction and for being a technology that requires low operational dedication. Although it is a technology vastly used in Brazil, there is not much information about the characteristics of the wa
