1. Numerical Study on Ultimate Behaviour of Bolted End-Plate Steel Connections
Abstract Bolted end-plate steel connections have become more popular due to ease of fabrication. This paper presents a three dimension Finite Element Model (FEM), using the multi-purpose software ABAQUS, to study the effect of different geometrical parameters on the ultimate behavior of the connection. The proposed model takes into account material and geome

2. Severe Loading Assessment of Modern and New Proposed Beam to Column Connections
AbstractThe performance of two different steel beam to column connections known as SidePlateTM and a new proposed connection by seismic loading and progressive collapse were investigated in this research. Seismic performance evaluated included consideration of interstory drift angles and flexural strengths based on 2010 AISC Seismic Provisions while investig

5. Contribuições para melhoria do desempenho e viabilidade de fabricação de scanners indutivos / Contributions to improve the performance, and the manufacture viability of inductive scanners
Scanners are devices that deftects a light beam and converts a spot light in a well controlled amplitude and frequency scan line. Several applications uses the generated pattem to code or decode data, common examples ar,e barcode readers, and laser printers. A light beam can be deftected by different means. In this work, the scanner deftects the light by ref

6. Arquibancadas temporárias utilizadas em eventos urbanos : análise de projetos
In this work, an investigation is carried out concerning temporary grandstands employed in urban events. Some grandstand models are presented, including their components and structural systems. Aspects regarding the procedure adopted by public agencies in the inspection of this type of structure are also presented. The analyses were focused on the dynamics o

7. Estimation of the SEA coupling loss factors by means of spectral element modeling
The coupling loss factors are of critical importance when building and solving Statistical Energy Analysis (SEA) models. This paper proposes a methodology to numerically estimate these factors for frame-type structures. The estimated factors are compared with those obtained through analytical expressions for frame structures, where members are joined at righ

8. ANÁLISE DE DIFERENTES PROCESSOS SUBTRATIVOS UTILIZADOS NO TRATAMENTO DA SUPERFÍCIE DE IMPLANTES ODONTOLÓGICOS DE TITÂNIO CP / EXPERIMENTAL STUDIES OF DIFFERENT SURFACE TREATMENTS APPLIED TO TITANIUM DENTAL IMPLANTS
Titanium alloys are widely used in dental implants in virtue of clinical evidences of the excellent biocompatibility performance shown by this alloys. However, there are still a number of unanswered questions regarding the ideal physicochemical properties of titanium surfaces used in dental implants aiming at an appropriate integration with the bone. Further

9. Intervillous connections in the mature human placenta: instances of syncytial fusion or section artifacts?
In order to investigate the nature of apparent intervillous syncytial connections in the normal mature human placenta, 250 examples were followed through plastic serial sections at 2 micron intervals. It was possible to classify them into four types according to their origin. Type 1 (20%): section through an area of syncytial fusion or genuine bridge; Type 2

10. Retrograde transport of gamma-amino[3H]butyric acid reveals specific interlaminar connections in the striate cortex of monkey.
Several lines of evidence suggest that gamma-aminobutyric acid is an inhibitory neurotransmitter in the cerebral cortex. To study the intracortical projection of neurons that selectively accumulate this amino acid, we injected radioactive gamma-aminobutyric acid into the upper layers of the striate cortex of monkeys along tracks at an oblique angle to the pi
