Evaluation of prestress losses in concrete beams using destructive and non‐destructive methods

Structural Concrete, EarlyView.
Abstract Over the past few decades, prestressing techniques have become essential in the construction of key structures, infrastructure, and bridges. The serviceability and safety of prestressed concrete (PC) elements are closely tied to the effectiveness of the prestressing process.

Influence de l'orientation de l'outil sur les forces générées en FSW [PDF]

, 2013
Friction Stir Welding (FSW) est considéré comme un procédé de soudage à l’état solide très demandé pour souder des alliages d'aluminium. Au cours des dernières années, les chercheurs se sont orientés vers l’industrialisation de ce procédé.

Multi-objective optimization of the process combining ultrasonic vibration and age-forming of dissimilar friction-stir-welded Aluminium T-stiffened plates

Manufacturing Review
This paper innovatively proposes a combined process combining ultrasonic vibration (abbreviated UV) with creep age forming (abbreviated CAF), named UVCAF, for high-quality forming of dissimilar 7055-T6/2197-T8 FSWed T-stiffened plates. And based on this,

Correction: A comparative study of flexible ultrasonic-enhanced FSW (FLEX-USE-FSW) and conventional FSW in AA6082-T6

Welding in the World
Abstract This study presents a comparative analysis between conventional friction stir welding (CFSW) and flexible ultrasonic-enhanced friction stir welding (FLEX-USE-FSW) applied to a 3-mm-thick AA6082-T6 aluminum alloy. A novel ultrasonic system integrated into the tool holder was employed to introduce axial ultrasonic vibrations ...

Compromised DNA replication in gut cells underlies sensitivity to genotoxic stress in the tardigrade Hypsibius exemplaris

The FEBS Journal, EarlyView.
DNA damage in the tardigrade Hypsibius exemplaris elicits distinct cellular outcomes depending on replication status. While non‐replicating cells tolerate genotoxic stress, constitutively replicating cells undergo irreversible replication failure upon DNA damage, leading to loss of tissue homeostasis, fat depletion, sterility, and organismal death ...

Legal status, sex work engagement and inequities in the HIV pre‐exposure prophylaxis cascade among migrant women in 11 European countries

HIV Medicine, EarlyView.
Abstract Background Migrant women account for a substantial proportion of new HIV diagnoses in Europe, yet remain underrepresented in HIV prevention research. Little is known about how legal status and national policy context shape engagement with PrEP among migrant women, particularly those without secure documentation.
