Durable. Vous avez dit durable ? [PDF]

open access: yesTraduire, 2013
Quand j’entends l’expression « developpement durable », je ne sors pas mon revolver mais je ne peux m’empecher de penser a une reflexion d’Hercule Poirot dans un episode d’Agatha Christie. Nous sommes sur une scene de meurtre. Les policiers s’affairent autour du cadavre, mais Poirot porte son attention sur un fauteuil et demande : « Ce fauteuil a-t-il ...

Seismic Performance of LRS-FRP–Concrete–Steel Tubular Double Coupling Beam

open access: yesApplied Sciences, 2021
To improve the ductility and seismic performance of a double coupling beam, the authors applied a polyethylene terephthalate (PET) sheet and steel tube to form fiber-reinforced polymer (FRP)–concrete–steel double-skin tubular (DST) composite coupling ...

A Quality‐Driven Framework for Local Fatigue‐Strength Assessment of Wind–Energy Structures Considering Size Effects

open access: yesWind Energy
Reliability, safety, and the lifetime of wind energy systems are mainly driven by the quality of each single component. Especially, large structures made of cast material or welded structures, such as the nacelle, the machine carrier, or the tower, are ...

Sirolimus for Extracranial Arteriovenous Malformations: A Scoping Review of the Evidence in Syndromic and Non‐Syndromic Cases

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Arteriovenous malformations (AVMs) are rare, high‐flow, vascular anomalies that can occur either sporadically or as part of a genetic syndrome. AVMs can progress with serious morbidity and even mortality if left unchecked. Sirolimus is an mTOR inhibitor that is effective in low‐flow vascular malformations; however, its role in AVMs is unclear.

Experimental and numerical analyses of stiffness and fatigue properties of a spring element for mounts with tunable stiffness made of C85S+QT sheet steel

open access: yesFracture and Structural Integrity
Mounting stiffness has an important impact on a system’s structural dynamics and also on the durability of many structures. Mounts with tunable stiffness allow adapting a system’s structural dynamic behavior.
