25. TURISMO E SEGURANÇA PÚBLICA
Violence, a multiform phenomenon that involves a complexity of conflicts and behaviors, has become a drama that is associated with predominantly social causes, which take on alarming forms and dimensions in society contemporary. The fear generated by the violence disrupts the social life, and this is affecting peoples mobility, not only altering daily routin

26. Sustentabilidade de sistemas de produção de grãos : caso do arroz de terras altas
The objective of this study was to create an instrument to enable dialogue among stakeholders and provide information to manage the sustainable development of a grain cropping system regarding on decision making in regard to the types and intensities of intervention and/or field management practices. A method for upland rice has been developed and applied in

29. Essays in Corporate Risk Management
This research investigates the factors that lead Latin American non-financial firms to manage risks using derivatives. The main focus is on currency risk management. With this purpose, this thesis is divided into an introduction and two main chapters, which have been written as stand-alone papers. The first paper describes the results of a survey on derivati

30. Theoretical and experimental analysis of cold-formed steel members under compression / Análise teórica e experimental de perfis de aço formados a frio submetidos à compressão
Cold-formed steel members present, in general, higher local slenderness than classical hot- rolled ones, which make them more prone to local buckling. Besides, thin-walled open sections have small torsional stiffness, and hence global torsional and flexural-torsional instability modes are many times more critical than global flexural ones. Also, distortional

31. An ecological and economical zoning proposal for the Environmental Protection Area of Tambaba, in the state of Paraíba / Proposta de zoneamento ecológico econômico para a área de proteção ambiental (APA) estadual de Tambaba - Paraíba
This work is a proposal of an ecological and economical zoning (ZEEZoneamento Ecológico Econômico, in Portuguese) for the Environmental Protection Area (APAÁrea de Proteção Ambiental, in Portuguese) (both categories used by IBAMA, the Brazilian Institute for the Environment and Natural Resources) at Tambaba on the littoral of Paraíba state. The APA of

32. Análise teórico-experimental de sistemas aporticados com elementos perfurados em perfis formados a frio - Racks
Industrial Storage Racks are used in warehouses, because they improve the space occupation, and let easy access to the products. They are built with cold formed profiles, and presents the instability phenomena like local and distortional modes, common in thin-walled members. The uprights of these structures shows holes to make easy the assemblage. There are

33. Influência das vibrações do cabo na instabilidade aeroelástica de uma viga simples estaiada. / Influence of cable vibrations on the aero-elastic instability of a cable-stayed beam.
This paper is concerned with determining wind critical velocities and post-critical vibration amplitudes in a cable-stayed beam, under wind-rain condition. It is considered the cable sag due to the dead load plus the non-linear coupling between the vibration of both the cable and the beam. Three modes are of special interest, namely the first global mode (be

34. Estudo da dinâmica costeira da região da foz do rio Piranhas-Açu para geração de mapas de sensibilidade do litoral ao derramamento de óleo
The study area is located in the northern coast of Rio Grande do Norte State comprising the mouth of Açu-Piranhas river including the cities of Porto do Mangue e Areia Branca. The local geological setting comprises Cretaceous, Tertiary and Quaternary geological units of the Potiguar Basin. One is about a region of high morphologic instability due to action

35. Time variability of sea surface parameters in the tropical Atlantic using satellite and in situ data
The influence of the tropical Atlantic Ocean over the climate of Europe, Africa and America is well known today. However, several questions about high-frequency processes in this region remain open. This thesis addresses the characterisation of the diurnal and other short timescale variability of the meteo-ocean variables measured in the tropical Atlantic Oc

36. Construção e testes de máquina de ensaio de torção plástica para levantamento do comportamento plástico de metais
A computerized prototype machine for cold torsion testing has been developed, constructed and tested in the Laboratory of Metal Forming at UDESC (University the State the Santa Catarina) - Joinville. The equipment consists of a horizontal torsion machine, employing an electric motor, a wheel, a horizontal axle and a control and acquisition data system. The g
