Debonding mechanisms of fibre reinforced polymer strengthened steel members. [PDF]

open access: yes, 2011
Applying Fibre Reinforce Polymer (FRP) to steel structures has been proved to be an effective method of strengthening. Experimentally, ageing steel structures such as bridge decks and composite beams which have been strengthened with FRP have shown ...

Metastatic niche shaped by host factors influences disseminated cancer cell fate

open access: yesFEBS Letters, EarlyView.
Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...

S. João de Loure Bridge: vulnerability assessment and study of a common strengthening solution [PDF]

open access: yes, 2005
This paper presents a structural vulnerability assessment of the steel bridge S. João de Loure. A structural model of the bridge was created and the influence of the joint’s stiffness on its structural response was evaluated using the structural analysis

Metastasis on pause: How dormant tumor cells stay hidden within the tumor microenvironment and evade immune surveillance

open access: yesMolecular Oncology, EarlyView.
Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...

Vulnerability assessment of the S. João de Loure Bridge: Vouga’s river [PDF]

open access: yes, 2005
Steel bridges are particularly sensible to corrosion, which can put at risk the structural safety by affecting the joint elements. Having this in mind, the objective of this work was to evaluate the influence of the joint's stiffness in the structural ...

Sustainability of bridge maintenance [PDF]

open access: yes, 2019
Bridge maintenance activities are important to consider within sustainable development due to the cost and environmental impact associated with various maintenance activities. Comparisons have been made between different bridge structural forms, based on

The VHL tumor suppressor at the crossroad of protein folding, aggregation, and cancer

open access: yesMolecular Oncology, EarlyView.
Mutations, environmental stress, and chaperone dysfunction can destabilize pVHL, promoting its conversion from the native folded state into amyloid‐like assemblies. This transition may contribute to protein storage, cell dormancy, survival, and drug resistance.

Bridge roughness index as an indicator of bridge dynamic amplification [PDF]

open access: yes, 2006
The concept of a road roughness index for bridge dynamics is developed. The International Roughness Index (IRI) is shown to be very poorly correlated with bridge dynamic amplification as it takes no account of the location of individual road surface ...

Analysis of Mechanical Performance of Steel-Concrete Composite Girder Bridge with V-Shaped Piers

open access: yesAdvances in Civil Engineering, 2022
The steel-concrete composite girder bridge with V-shaped piers is a new type of bridge structure. It has both the unique mechanical performance of a combined continuous girder and that of a V-shaped pier bridge.
