1. Evaluation of the resistance of trussed slabs with steel formwork in cold formed U profile
Abstract In the last decades, the modernization in structural engineering has increased the use of steel-concrete composite and hybrid systems for slabs, when the adherence in the interface of the materials is present or not, respectively. In addition to the traditional steel deck, a similar solution for precast trussed slabs has been used for small construc

2. PREDICTION OF STABILITY AND THERMAL CONDUCTIVITY OF SnO2NANOFLUID VIA STATISTICAL METHOD AND AN ARTIFICIAL NEURAL NETWORK
Abstract Central composite rotatable design (CCRD) and artificial neural networks (ANN) have been applied to optimize the performance of nanofluid systems. In this regard, the performance was evaluated by measuring the stability and thermal conductivity ratio based on the critical independent variables such as temperature, particle volume fraction and the pH

3. Contribuição ao projeto e dimensionamento da superestrutura de pontes rodoviárias em vigas mistas de aço e concreto / Contribution to the project and design of superstructure of bridges composite beams of steel and concrete
Even the metal bridges known for overcoming large spans, designed and implemented by large offices, this paper wishes to present concepts that can be applied in practical design of Steel-Concrete composite bridges of short and medium span, because those are the most common in national highways, and there is also a lack of professionals to design them into st

4. Environmentally responsive polymeric "intelligent" materials: the ideal components of non-mechanical valves that control flow in microfluidic systems
Miniaturization and commercialization of integrated microfluidic systems has had great success with the development of a wide variety of techniques in microfabrication, since they allowed their construction at a low cost and by following simple step-series procedures. However, one of the major challenges in the design of microfluidic systems is to achieve co

5. AVALIAÇÃO DO COMPORTAMENTO ESTRUTURAL DE CONECTORES PERFOBOND E T-PERFOBOND PARA VIGAS MISTAS / ASSESSMENT OF PERFOBOND CONNECTOR BEHAVIOUR FOR COMPOSITE BEAMS
Steel and composite beams have been extensively used in buildings and bridges. The component that assures the shear transfer between the steel profile and the concrete deck, enabling the composite action to develop, is the shear connector. Among the different types of connectors the headed studs, C sections and the Perfobond may be referred. An alternative c

6. COMPOSITE SLAB SYSTEM FOR RESIDENTIAL CONSTRUCTIONS USING COLD FORMED STEEL PLATES WITH EMBOSSMENTS / SISTEMA DE LAJE-MISTA PARA EDIFICAÇÕES RESIDENCIAIS COM O USO DE PERFIS EMBOSSADOS DE CHAPA DOBRADA
Nos trabalhos já concluídos nesta linha de pesquisa foram desenvolvidos protótipos de deck-metálico (steel-deck), empregando-se diversas formas de ligação entre a chapa de aço e o concreto armado, tais como: corrugações de alma (Andrade, 1986), parafusos auto-brocantes (Takey, 2001), septos em perfís tipo bandeja (Vieira, 2003) e corrugações circ

7. Comportamento dos sistemas adesivos com fluor frente ao desafio cariogenico
The aim of this study was to investigate the behavior of fluoride-free and fluoride-containing adhesive systems subject to dynamic chemical induction of secondary caries, by means of the microtensile bond strength test, establishment of carious lesion depth and the amount of fluoride-ion release from each adhesive system. Eighty extracted bovine incisors wer

8. Numerical analysis of beams composed of concrete and wood / Analise numerica de vigas mistas em concreto e madeira
The technologycal development of the design in wood structures has improved the knowledge of the material mechanical properties and the connection systems applied to structures. Composite structures of wood with concrete or steel and structural reinforcement using polymer fibers have become a reality. These structures, constituted by associating materials wi

10. DESENVOLVIMENTO DE SISTEMAS ESTRUTURAIS SEMI-RÍGIDOS EM AÇO E MISTOS PARA EDIFICAÇÕES RESIDENCIAIS MULTI-FAMILIARES / SEMI-RIGID COMPOSITE SYSTEMS FOR RESIDENTIAL BUILDINGS
Nowadays, despite the substantial increase in structural design knowledge, the semi-rigid connections steel design is still facing resistance from the structural engineers. This fact can be in part explained by few design standards that allows and explains their use, suitable computer programs and the lack of detailed information of the economical advantages

11. El tiempo de la historia
An inquiry from Vico's formulation of the general idea of history leads to a reinterpretation of the way Marx deals with the general notion of "history", which is not understood as the linear continuity of different production systems, but as the genesis of some systems' conditions from others' integral elements. It is singled out that Althusser has been the
