1. Effects of Different Plasma Nitrided Layers on the Tribological Performance of DLC Coatings
When multifunctional surface engineering processes that combine purpose-oriented phases are applied to soft substrates, a combination of high wear resistance, high load support and low coefficients of friction can be achieved. In this study, the effects of different nitrided layers on the tribological behaviour of a diamond-like carbon (DLC) film deposited o

2. Methods of data analysis for the ball cratering test on TiN and DLC coated steel
Titanium nitride (TiN) coatings are widely used in machining because of its mechanical characteristics which modify the surface of the substrate increasing the capacity of load support and reduction of friction, while a coating as diamond-like carbon (DLC), which also has interesting mechanical properties, needs better attention. In this sense, the developme

3. Analysis of flicker level on the integration of fixed speed wind generators using multidiscipline models / Análise dos níveis de flicker na integração de geradores eólicos de velocidade fixa em redes de distribuição de energia elétrica utilizando modelos multidisciplinares
The discussions about the environmental issues and the need for renewable sources of energy, with low environmental impacts, mainly about CO 2 emission, have encouraged the Wind Energy expansion. The support for wind energy in the last decades enabled the improvement of the technology and a representative share in the electrical systems of some countries. Th

4. Análise da influência de um calçado flexível e desprovido de salto sobre a mecânica da marcha e a carga articular de indivíduos com osteoartrite de joelho / Influence of flexible footwear and without heel on the gait mechanics and joint loading in individuals with knee osteoarthritis
The literature has been given evidences that the use of flexible and non-heeled footwear that reproduces the kinematic and kinetic characteristics of barefoot gait may reduce the joint loads and the progression of the knee osteoarthritis (OA). The purpose of this study was to evaluate and compare the influence of the acute use of flexible, non-heeled and ine

5. Atributos mecÃnicos e salpicamento de partÃculas em amostras de latossolo vermelho-amarelo sob efeito de vinhaÃa / Mechanical attributes and splash of particles of samples of red-yellow latosol (Oxisol) under effect of vinasse
With the increased production of ethanol and cachaÃa in Brazil, also increases the production of vinasse, main residue of the industrialization of sugarcane. One way of its utilization is its disposal in soil as liquid fertilizer. The vinasse can change the physical attributes of soil and its compressive behavior and the resistance of soil aggregates to spl

6. Assessment of the Cambisol structure sustainability under different land uses systems in Western Amazon. / AvaliaÃÃo da sustentabilidade da estrutura de um Cambissolo sob diferentes sistemas de uso da terra na AmazÃnia Ocidental.
The adequate use of the soil is important for the preservation of the natural resources and for a search of a sustainable agriculture. However, itâs inadequate use promotes degradation of the soil altering its physical, chemical and biological properties. In order for the soil management happens in a sustainable way it is important to diagnose through effic

8. Automação como recurso de planejamento de redes de distribuição de energia elétrica. / Automation as resource for distribution systems planning.
Concerning the components of an electrical distribution network and their susceptibility to functional failures or need for maintenance actions, planning and project criteria should be adopted to assure continuity of energy supply even though some components may be out of work. Traditionally the power systems, especially in power transmission and distributio

9. Formação e gestão de redes de cooperação empresarial. / Formation and management of networks.
The increasing complexity of the production processes modified the traditional form of the production management operations and created a new challenge to the companies. In a similar way that the first capitalist challenge demanded the spelling of the workmanship hand, in the beginning of century XX, in the beginning of century XXI appears a new challenge in

10. Domestic wastewater post-treatment using ornamental plants : Constructed-Wetlands with gravel and bamboo as substrate / Plantas ornamentais no pos-tratamento de efluentes sanitarios : wetlands-construidos utilizando brita e bambu como suporte
Anaerobic reactor s effluent post-treatment systems make possible the improvement of anaerobic-treated wastewater characteristics in diverse conditions in a simple way. This posttreatment design flexibility will be able to support small communities to have better environmental conditions even if they did not have a traditional wastewater plant previously. Th

11. Shear strength and compressibility of a Latosol under different uses and weed management / ResistÃncia ao cisalhamento e compressibilidade de um Latossolo sob diferentes usos e manejos.
Soil compaction has been pointed out as one of the main process of yield reduction of a number of farming activities. Amongst the affected activities, the ones that suffer the most from this problem are the ones that preserve the soil structure, namely, those which do not imply in having the annual soil tillage. Grasslands and no-tillage planting of maize fi

12. Effects of proportional assist ventilation on exercise capacity in idiopathic pulmonary fibrosis patients / Efeito da ventilação assistida proporcional na capacidade ao exercício em pacientes com fibrose pulmonar idiopática
The objective of the present study was to evaluate the effect of ventilatory support using proportional assist ventilation (PAV) on exercise capacity in patients with idiopathic pulmonary fibrosis. Ten patients were submitted to a cardiopulmonary exercise testing, lung function and 3 submaximal exercise tests (60% of maximum load): without ventilatory suppor
