1. SPRAY RETENTION ON COFFEE LEAVES ASSOCIATED WITH TYPE AND CONCENTRATION OF ADJUVANTS
ABSTRACT Agricultural spray adjuvants (ASA) are widely used in pesticide applications to enhance the performance of pesticides. The aim of this research was to investigate the effects of ASA on static surface tension (SST) and foliar spray retention on coffee leaves. The SST of ASA at different concentrations was determined by the drop weight method. Spray r

2. Performance and Surface Integrity of Wire Electrical Discharge Machining of Thin Ti6al4v Plate Using Coated and Uncoated Wires
Wire Electrical Discharge Machining (WEDM) is one of the most important production technologies to manufacture very accurate small components and tools on any electrical conductive material. Titanium and its alloys have been widely used in automobile and aerospace industry as well as in medical engineering field. Small components and tools with complex geome

3. Run time Assessment for Gas Turbine Performance Simulation
ABSTRACT: This article describes the run time characteristics of a gas turbine performance simulation using different solvers and components off-design performance database formats. Two different nonlinear systems of equation solvers, Newton-Raphson's and Broyden's, and two different formats of compressor and turbine off-design performance database (maps), t

4. PESTICIDES DEPOSITION IN VINEYARDS ON DIFFERENT CONDITIONS OF LEAF WETNESS
ABSTRACT The high susceptibility to diseases of fine table grapes cultivars demand intensive use of pesticides, and the presence of water on the leaf surface can worsen the deposition of these products. The objective of this study was to evaluate the spray deposition in vine leaves in different conditions of leaf wetness, and test the effectiveness of an art

5. DISPONIBILIDADE E TRANSFERÊNCIA DE NITROGÊNIO, FÓSFORO E POTÁSSIO EM UM ARGISSOLO SUBMETIDO À APLICAÇÃO DE FONTES DE NUTRIENTES / AVAILABILITY AND TRANSFER OF NITROGEN, PHOSPHORUS AND POTASSIUM IN SANDY TYPIC HAPLUDALF SOIL SUBMITTED TO THE APPLICATION OF SOURCES OF NUTRIENTS
The swine and cattle activities are of great economic and social importance in Brazil in the southern region, but generate of large volumes of waste, that when applied to the soil can be mineralized and part of the nutrients released can be absorbed by plants or transferred by runoff or percolation. The aimed of this study was to evaluate the rate of mineral

6. The use of the linkage technique in health information systems: application in the database of the São Paulo Population-based Cancer Registry / Uso da técnica de linkage nos sistemas de informação em saúde: aplicação na base de dados do Registro de Câncer de base populacional do município de São Paulo
The availability of large computerized databases on health has enabled the record linkage technique, an alternative for different study designs. This technique provides the generation of a more complete database, at low operational cost. Objective to investigate the possibility of completing/improving information from the database of the RCBP-SP, in the peri

7. Determinantes ecológicos do risco de extinção: abundância local, amplitude de nicho, capacidade de dispersão e a resposta das espécies de pequenos mamíferos à fragmentação florestal no Planalto Atlântico Paulista / Ecological determinants of extinction risk: local abundance, niche breadth, dispersal ability and response of small mammals to forest fragmentation at the Atlantic Plateau of São Paulo
Anthropogenic disturbances, particularly habitat loss and fragmentation, are considered the main causes of the increased extinction rates observed in the last decades. Since the risk of extinction is extremely variable among species, the ecological determinants of the chance of extinction have been in the center of the debates in the ecological literature. E

8. Amortecimento superficial nos sistemas de micro-drenagem em regiões de baixa declividade. / Peak flow reduction for micro-drainagem systems applied to flat areas.
O presente trabalho desenvolve uma proposta para a avaliação da redução da vazão de pico do hidrograma do método racional, no contexto de bacias hidrográficas topograficamente planas. Entendem-se como planas aquelas localidades, cujas declividades médias características e/ou projetadas são inferiores a 0,5%. Pretende-se também neste trabalho apres

9. Maze routing steiner trees with delay versus wire length tradeoff
In this paper, we address the problem of generating good topologies of rectilinear Steiner trees using path search algorithms. Various techniques have been applied in order to achieve acceptable run times on a Maze Router that builds Steiner trees. A biasing technique proposed for wire length improvement, produces trees that are within 2% from optimal topolo

10. Conceitualização de um sistema de suporte à decisão para o dimensionamento e manejo de pivô central em condições de irrigação de precisão.
RESUMO: Embora a água seja um dos principais componentes de produção a afetar a produtividade das culturas, sua variabilidade dentro da área irrigada é frequentemente ignorada. Acredita-se que isto seja devido à falta de instrumentos confiáveis para sua medição em tempo real como, por exemplo, aqueles existentes para medição de nitrogênio. Nota-s

11. Electoral rules, political competition and fiscal spending: regression discontinuity evidence from brazilian municipalities
We exploit a discontinuity in Brazilian municipal election rules to investigate whether political competition has a causal impact on policy choices. In municipalities with less than 200,000 voters mayors are elected with a plurality of the vote. In municipalities with more than 200,000 voters a run-off election takes place among the top two candidates if nei
