1. Fatigue analysis and life prediction of composite highway bridge decks under traffic loading
Steel and composite (steel-concrete) highway bridges are currently subjected to dynamic actions of variable magnitude due to convoy of vehicles crossing on the deck pavement. These dynamic actions can generate the nucleation of fractures or even their propagation on the bridge deck structure. Proper consideration of all of the aspects mentioned pointed our t

2. Pó de borracha reutilizado na confecção de compostos de borracha natural para a produção de peças de engenharia do setor automotivo
Due to the cross-linked structure and the presence of antidegradants, rubber products decomposition is very hard and the disposal of waste material has been caused many environmental problems. Therefore, rubber recycling and the use of it as raw material in fresh rubber compounds are strongly necessary to achieve more sustainable technological projects. The

3. A influência do trabalho no rendimento escolar dos estudantes trabalhadores de graduação de enfermagem: uma revisão integrativa. / The influence of work on school performance of students graduate nursing workers: an integrative review.
The constant demand for qualified and up to date professionals has led increasingly professionals already working in the labor marketing to colleges and universities, increasing the number of working students in nursing undergraduate courses in the area. The economic reality does not allow these students to only study, particularly in private colleges. They

4. Investigação experimental da fadiga em lajes de pontes armadas com barras ou telas soldadas. / Experimental investigation of fatigue in bridge slabs reinforced with rebars or steel mesh.
Este trabalho apresenta estudos, ensaios e análises de resultados a respeito do comportamento à fadiga das estruturas de concreto armadas com barras isoladas e telas soldadas, começando pelas lajes de pontes, seus elementos mais sensíveis à fadiga. A parte experimental desta pesquisa consiste na investigação experimental do comportamento à fadiga de

5. Investigação experimental da fadiga em lajes de pontes com ou sem pré-lajes. / Fatigue experimental research on bridge slabs or pre-slabs.
As lajes dos tabuleiros de pontes de concreto armado, sejam elas maciças ou executadas com pré-lajes, são elementos estruturais suscetíveis à fadiga, devido às ações a que são submetidas. As pré-lajes, pelo fato de serem resultantes da junção de dois concretos diferentes, torna-se ainda mais suscetível à fadiga. Este trabalho apresenta estudos,

6. Verificação à fadiga de pontes rodoviárias mistas (aço-concreto) / Fatigue analysis of composite highway bridges
Steel and composite highway bridges (steel-concrete) are currently subjected to dynamic actions, for example, variable magnitude due to vehicles traffic on the deck rough pavement. These dynamic actions can generate the fractures nucleation or even their propagation on the structure. The correct consideration of these aspects pointed out to an analysis metho

7. AnÃlise de fadiga em juntas soldadas pelo processo MIG/LASER utilizando o mÃtodo dos elementos finitos / Fatigue Analysis of MIG/Laser Welded Joints with the Finite Element Method
The objective of this work is to deal with the analysis of MIG/Laser welded joints. The analysis method chosen is the Master S-N Curve Method, which is based on fracture mechanics principles and uses finite element results as inputs. This method was chosen due to the fact that it has been adopted by American Society of Mechanical Engineers (ASME) for develop

8. Obtenção do fator de intensidade de tensão pelo método da função de green local modificado
The stress intensity factor is of paramount importance at failure analysis, fatigue and fracture mechanics, this methodology is used when the cost is high and the safety essential. In this way, a lot of methods have been used and, among of them, one has the Finite Element and the Boundary Element methods, the first needs a fine mesh getting a high computatio

9. Cavitation Fatigue. Embolism and Refilling Cycles Can Weaken the Cavitation Resistance of Xylem1
Although cavitation and refilling cycles could be common in plants, it is unknown whether these cycles weaken the cavitation resistance of xylem. Stem or petiole segments were tested for cavitation resistance before and after a controlled cavitation-refilling cycle. Cavitation was induced by centrifugation, air drying of shoots, or soil drought. Except
