1. DIRECT CONNECTION PHOTOVOLTAIC SYSTEM IN MULTI-MOTOR APPLICATION FOR THE RURAL SECTOR
ABSTRACT Photovoltaic pumping systems equipped with variable speed drive have been consolidated as an alternative for water supply in rural locations where energy services are unavailable. Such systems are of the direct connection type and, therefore, it is likely that their operation occurs in two situations: when energy is available and when the reservoir

4. Non-infected penile prosthesis cultures during revision surgery; comparison between antibiotic coated and non - coated devices
ABSTRACT Introduction: Aim of this study is to investigate bacterial growth on non-infected devices and compare antibiotic-coated and non-coated implants. Materials and methods: The charts of 71 patients who underwent revision surgeries for penile prosthesis between 1995 and 2013 were reviewed. Of those, 31 devices were antibiotic-coated prostheses, while

5. Load Rate Effects in Adhesive Single Lap Joints Bonded with Epoxy/Ceramic Composites
Abstract The present paper is concerned with the analysis of the effect of the loading rate in a particular class of single lap joints used in the oil industry. The adhesive/adherend system consists of ASTM A36 steel plates bonded with an epoxy/ceramic composite. The loading rate sensitivity is analysed considering two different situations: (i) strain contro

6. Desafios e oportunidades da geração eólica e termelétrica a gás natural no Sistema Elétrico Peruano. / Challenges and opportunities of the wind generation and to natural gas thermal in the Peruvian Electricity System.
Several countries around the world have increasingly sought to diversify their electrical matrix in order to reduce dependence on fossil fuels and reduce emissions of gases responsible for worsening greenhouse effect in the atmosphere. As a result, has grown the participation of some renewable energy sources that until two decades ago did not occupied a prom

7. Efeitos da formação e operação de um reservatório de pequena regularização na alteração da qualidade da água e do regime hidrológico na planície de inundação do Pantanal
The formation of reservoirs changes the quality and quantity of water, both upstream and downstream, and the direction and magnitude of such changes depend on their characteristics of construction, operation, morphometry, as well as hydrological regime and climate of the region. However, much of this knowledge was based on large reservoirs, which is not the

8. Simulação do impacto da disponibilidade de sistemas no retorno econômico e produção de petróleo / Simulation of the impact of system availability on profit and petroleum production
The reservoir simulation is the basis for the forecasts of production, dimensioning of surface equipments and the planning of activities related to production. Therefore, a production strategy which generates oil and gas production curves over the operational lifetime. However, even without considering geological and economic uncertainties, in practice, this

9. Hidrossedimentologia e disponibilidade hÃdrica da bacia hidrogrÃfica da Barragem de PoilÃo, Cabo Verde / Hidrossedimentology and water availability of PoilÃo dam watershed, Cape Verde Islands
O ArquipÃlago de Cabo Verde, situado na costa ocidental africana, sofre influÃncia do deserto de Saara tornando o clima caracterizado por pluviometria muito baixa e distribuÃda irregularmente no espaÃo e no tempo. As chuvas sÃo muito concentradas, gerando grandes escoamentos para o mar. O aumento da disponibilidade hÃdrica requer alÃm da construÃÃo

10. Avaliação da composição isotópica do chumbo e da distribuição elementar nos sedimentos da represa Pedro Beicht, Cotia, São Paulo / Evaluation of isotopic composition of lead and elemental distribution in the sediments of the Pedro Beicht reservoir, Cotia, São Paulo
The water reservoir named Pedro Beicht provides water to five hundred thousand people in the metropolitan region of São Paulo city and is known by its excellent aquatic system quality. It is managed by Sanitation Company of São Paulo State (SABESP) and is surrounded by the Forest Reserve Morro Grande (RFMG). The RFMG was created in 1979 to ensure flora and

11. Methodology for the Design of Cover Systems Based on the Case Study Conducted at Site Rio Paracatu Mineração (RPM) in Paracatu, Minas Gerais / Metodologia para Dimensionamento de Sistemas de Cobertura com Base em Estudo de Caso Realizado na Mina da Empresa Rio Paracatu Mineração (RPM) em Paracatu, Minas Gerais
Nearly four years ago, two experimental cover systems of the evapotranspirative type, have been designed and built in Rio Paracatu Mineração (RPM), Paracatu, Minas Gerais (Amorim, 2008). One cover system was made with a hydraulic barrier layer and the other with a capillary barrier layer, both with monitoring systems consisting of a runoff meter, lysimeter

12. RESTARTABILITY OF VISCOPLASTIC MATERIALS IN PIPES / REINÍCIO DE ESCOAMENTO DE MATERIAIS VISCOPLÁSTICOS EM UM TUBO
On of the main problems in the operation of subsea pipelines that convey paraffin oils is the flow startup after long stoppages. Along the path from the reservoir to the platform, the oil experiences significant heat losses, especially to the low-temperature water at the sea bottom. When there is no flow, the oil may reach very low temperatures. Cooling indu
