1. Mechanics of Cable-Suspended Beams
Abstract The cable-suspended bridges differ from the elastic structures because of the inherent nonlinearity of the suspension cables. The primary focus of the available theories is to investigate the effect of nonlinearities associated with the distributed self-weight of the cable and its finite elastic displacements. The main point of departure of this pap

2. Strand Tension Control in Anchor Span for Suspension Bridge Using Dynamic Balance Theory
Abstract Strand tension control is essential in suspension bridge safety. However, few quantitative studies have examined the bending rigidity and boundary condition behavior of strands in the anchor span of suspension bridges because of their special structure and complex configuration. In this paper, a new calculation method for strand tension is explored

3. Wind tunnel test for vortex-induced vibration of vehicle-bridge system section model
Vortex-induced vibration of bridges happens at a relatively low wind speed and while vehicles often run on a bridge at that wind speed. Thus, it is necessary to study how the vehicles influence vortex-induced vibration of vehicle-bridge systems. Based on the project of Shanghai Bridge over Yangtse River, the wind tunnel test for vortex-induced vibrations of

4. Metodologia para atualização de modelos numéricos de pontes com base em dados experimentais
Bridges are structures that due their immense dimension, long spans, long service life and structural complexity, need a regular inspection and condition assessment to guarantee their serviceability, safety and reliability. The modal model of the bridge based on dynamic measurement has been a tool to evaluate these structures. A system identification procedu

5. Ana-PSp: a computational system for aeroelastic analysis of suspended bridges for reduced mathematical models. / ANA-PSp: um sistema computacional para análise aeroelástica de pontes suspensas por modelos matemáticos reduzidos.
As características arquitetônicas e o desempenho estrutural de pontes suspensas, estaiadas ou pênseis, têm determinado a sua crescente utilização em obras de arte destinadas a vencer grandes vãos. Essa utilização crescente que ocorreu no mundo nas últimas décadas se repete agora nos últimos anos no país. Várias dessas obras estão em execução

6. Precast stress-ribbon pedestrian bridges / Passarela pênsil protendida formada por elementos pré-moldados de concreto
Este trabalho aborda um tipo de passarela que está ganhando bastante notoriedade internacionalmente. Inúmeras obras vêm sendo construídas em diversos países, embora no Brasil ainda seja quase desconhecida. Basicamente, a estrutura é composta por cabos livremente suspensos, sobre os quais se apóia o tabuleiro formado por elementos pré-moldados de conc

7. Isolation of a 90-kD Microtubule-Associated Protein from Tobacco Membranes.
The organization and function of microtubules in plant cells are important in key developmental events, including the regulation of directional cellulose deposition. Bridges connecting microtubules to each other and to membranes and other organelles have been documented by electron microscopy; however, the biochemical and molecular nature of these linkages i

8. Propeptide of a precursor to a plant vacuolar protein required for vacuolar targeting.
Sporamin is a protein without glycans that accumulates in large quantities in the vacuoles of the tuberous root of the sweet potato. It is synthesized as a prepro precursor with an N-terminal extension composed of a 21-amino-acid signal peptide and a 16-amino-acid propeptide. A total of 48 base pairs, corresponding to the nucleotide sequence that encodes the
