1. PERFORMANCE OF AIR INDUCTION SPRAY NOZZLE MODELS UNDER DIFFERENT OPERATING CONDITIONS
ABSTRACT For the successful application of phytosanitary products, it is essential to understand the spraying process well. The present work aims to evaluate the spectrum and speed of the droplets produced by different spray nozzle models with air induction, working under different operating conditions. The experiment was conducted using an entirely randomiz

2. Characterization of a pediatric rotary blood pump
Abstract Introduction A ventricular assist device (VAD) is an electromechanical pump used to treat heart failures. For designing the physiological control system for a VAD, one needs a mathematical model and its related parameters. This paper presents a characterization procedure for determining the model parameter values of the electrical, mechanical, and

4. Caracterização batimétrica e fisicooceanográfica do canal de acesso ao porto de Cabedelo/PB: uma análise ambiental ao derrame de óleo
The State of Paraíba is one of the most dynamic states of Brazil, strategically located in the northeast, is notable for the excellent potential for integration of different transportation modes forming the states of Rio Grande do Norte, Pernambuco and Alagoas. The dynamic that occurs with port activity causes changes in the space where it is installed. And

5. Influencia de la cantidad de O2 adicionado al CO2 en el gas de protección sobre la microestructura del metal depositado en uniones soldadas de bordes rectos en aceros de bajo contenido de carbono con el proceso GMAW
The presence of acicular ferrite (AF) in the microstructure of weld bead, in a specified range of values, increase considerably the toughness of welded joints. The present paper, for that reason, study the relationship between the acicular ferrite quantity in the deposited metal and the oxygen present in the active gas mixture of CO2+O2, during the execution

6. Caracterização do fluxo de tráfego em rodovias de pista simples do Estado de São Paulo / Characterization of the traffic flow on two-lane rural highways in the state of São Paulo
The goal of this research was to characterize the fundamental relationships of traffic flow on two-lane rural highways in the state of São Paulo through models based on parameters that reflect the quality of service and that could be obtained from direct observations of traffic flows. To reach this goal, sets of data were obtained from observation of traffi

7. Project and assembling of pneumatic transport pilot unit in diluted phase for studying the relationship between the pressure drop and the distribution of granular particles into the cross section of industrial pipes / Projeto e montagem de unidade piloto de transporte pneumatico em fase diluida para estudo da relação entre a perda de carga e a distribuição de particulas granulares na seção transversal de dutos industriais
The pneumatic transport that involves the use of air particles to move materials through pipes is a major operation in various industries and chemical processes. Typical examples are systems for the conversion of energy from coal, catalytic cracking, drying and transport of solid and fine granular. The conventional pneumatic transport is often operated in di

8. Influência das características viário-ambientais nos parâmetros dos modelos microscópicos de fluxo de tráfego / Influence of road environment factors on the microscopic traffic models parameters
The starting point of this work is the supposed influence of road environment factors on drivers behavior, interfering in the values of the microscopic traffic models parameters. This work aims at verifying the influence between these factors and the drivers behavior by means of the variations in the parameters of traffic models. Thus, this research investig

9. Improvement of lipase production at different stirring speeds and oxygen levels
Lipase production by a Brazilian wild strain of Yarrowia lipolytica at different stirring speeds and air flow rates was studied. The relationship among lipid consumption, cell growth and lipase production by this microorganism is presented. The most pronounced effect of oxygen on lipase production was determined by stirring speed. Maximum lipase activity was

11. Processo decisório: a utilização do sistema de informação como apoio ao processo decisório
Information is found everywhere, and with current technological possibilities we have access to extraordinarily wide volumes of it in every possible aspect. In this context, organizations, which are based in processes, generate information in a determined flow that must be controlled in such a way that we can have access to it at the times and in the amount

12. Slipping or Gripping? Fluorescent Speckle Microscopy in Fish Keratocytes Reveals Two Different Mechanisms for Generating a Retrograde Flow of ActinV⃞
Fish keratocytes can generate rearward directed traction forces within front portions of the lamellipodium, suggesting that a retrograde flow of actin may also occur here but this was not detected by previous photoactivation experiments. To investigate the relationship between retrograde flow and traction force generation, we have transfected keratocytes wit
