13. Local/Distortional/Global buckling mode interaction on thin walled lipped channel columns
The buckling behaviour of pin ended cold-formed steel lipped channel columns affected by local / distortional / global buckling mode interaction under axial loading is simulated by using finite element software ABAQUS, and the results are compared with the test results available in the literature. The comparisons show that the proper analysis model can simul

14. Study on the capacity of cold-formes steel built-up battened colums under axial compression
This paper presents the theoretical and numerical investigation results of the pin ended cold-formed steel built-up battened columns under axial compression. The finite element model was developed using the finite element software ABAQUS. The comparison of finite element analysis results match with the test results available in the literature shows that the

15. Avaliação do comportamento solo-estrutura de elementos de fundação tipo sapata estaqueada / Assessment of the behavior of soil-structure foundation elements like piled footing
This work aims to study the behavior and interaction between soil, shallow footing and pile, based on the implementation and monitoring of four direct load tests performed on: a single shallow footing, a shallow footing with one pile, a shallow footing with four piles and a pile alone. During the load tests, vertical displacements were monitored at different

16. Does the casting mode influence microstructure, fracture and properties of different metal ceramic alloys?
The aim of the present study was to evaluate the tensile strength, elongation, microhardness, microstructure and fracture pattern of various metal ceramic alloys cast under different casting conditions. Two Ni-Cr alloys, Co-Cr and Pd-Ag were used. The casting conditions were as follows: electromagnetic induction under argon atmosphere, vacuum, using blowtorc

17. Nanoparticle assisted coagulation of aqueous alumina suspensions
Colloidal processing of ceramics offers a high potential to achieve homogeneous microstructures with improved material properties. In this study, a novel forming method is investigated, which was already applied successfully for the fabrication of ceramic matrix composites (CMC), but is also considered to be a suitable direct casting technique for the fabric

18. In vitro evaluation of an alternative method to bond molar tubes
Despite the advances in bonding materials, many clinicians today still prefer to place bands on molar teeth. Molar bonding procedures need improvement to be widely accepted clinically. OBJECTIVE: The purpose of this study was to evaluate the shear bond strength when an additional adhesive layer was applied on the occlusal tooth/tube interface to provide rein

19. Avaliação dos tipos de processamento na descontaminação e na degradação do polipropileno reciclado / Evaluation of types of processing in the decontamination and degradation of recycled polypropylene
Polypropylene is one of the most used polymers worldwide, especially by the disposable packaging industry, causing serious environmental problems. Despite the fact that recycling this polymer has become common in Brazil due to its growing market, there are still some restrictions regarding its use in direct-contact food packaging. Therefore, in order to eval

22. A formação litúrgica no Brasil a partir da Sacrosanctum Concilium
This thesis written by Fabio de Souza Leão has as title: The liturgical formation in Brazil from Sacrosanctum Concilium. The main objective of this research is to analyze, although in general, why the catholic communities in Brazil did not find a satisfactory way in the liturgy, the source of their spirituality, even after the renewal of council with the pr
