13. Appled numericl modeling to the analysis of sea intrusion in the south of Recife Coastal Plain (PE) / Modelagem numÃrica aplicada à anÃlise da intrusÃo marinha na regiÃo sul da PlanÃcie do Recife (PE)
Groundwater is considered a safe and well protected source of water supply, and in some places it should be used as a strategic reserve. However, lack of adequate management in coastal aquifers has led to several problems, including seawater intrusion. Recife metropolitan region encompasses 14 towns and 14 mÂ/s of water supply demand, facing problems with d

14. Modelagem 3D e simulação dinamica do escoamento gas-solido em reator downer
The present work provides an unsteady, three-dimensional, two-phase, inviscid model of the solid phase, as an approach of the flow dynamics inside downer reactors of FCC processes, and the validation of the proposed model against experimental data available on the literature. Four geometrical configurations were evaluated to validate the proposed model: down

15. Modelagem chuva-vazão em bacias hidrograficas com suporte em redes neurais artificiais
This work describes the use of two hydrological simulation deterministic models to represent the rainfuJI-runnoff processo The Itapetiniga, Almas and Guarapiranga rivers basin, located in the State of São Paulo and the Guaporé river basin located in the State of Mato Grasso, are taken as a case study. Both deterministic models used parameters optimization,

16. Sistemas de workflow : analise da area e proposta de modelo
A special category of collaborative systems, the Workflow Systems, are discussed. Such systems can be defined as "systems that help organizations to specify, execute, monitor, and coordinate the flow of work items within a distributed office environment" [Bul92]. We identify basic structural and semantic issues in such systems, and show that improvements can

17. Modelagem hidrodinamica de um mecanismo pulso duplicador
Pulse duplicators simulators are useful devices in biomedical applications. They can simulate in vitro flow phenomena related to arterial blood flow such as: stenosis, aneurysms, bifurcations, vessel elasticity among others. The purpose of this work is two-fold: develop mathematicaltools to model and analyze pulse duplicators simulators and the propose a new

18. The role of the glycocalyx in reorganization of the actin cytoskeleton under fluid shear stress: A “bumper-car” model
We propose a conceptual model for the cytoskeletal organization of endothelial cells (ECs) based on a major dichotomy in structure and function at basal and apical aspects of the cells. Intracellular distributions of filamentous actin (F-actin), vinculin, paxillin, ZO-1, and Cx43 were analyzed from confocal micrographs of rat fat-pad ECs after 5 h of shear s
