Enhancing surface integrity in friction stir welding through deep rolling and post-weld heat treatment

Journal of Advanced Joining Processes
This study aimed to investigate mechanical surface treatment through deep rolling (DR) and post-weld heat treatment (PWHT) to enhance the surface integrity of an AA7075-T651 aluminum alloy welded through friction stir welding (FSW). The surface integrity

Engagement in sexual healthcare and STI/HIV burden of first- and second-generation migrant and Western-born female sex workers in the Netherlands: A retrospective cohort study

Journal of Migration and Health
Introduction: Scarcely available European studies suggest that migrant female sex workers (FSW) have a higher likelihood of sexually transmitted infections (STI) but a lower likelihood of HIV compared to non-migrant FSW. This study assessed demographics,

Transverse Oscillations and Kelvin–Helmholtz Instability in Curved Arcade Loops with Siphon Flows

The Astrophysical Journal
The effect of plasma flow in curved arcade loops on transverse waves and oscillations is examined analytically. The model under study is a semicircular magnetic slab with finite transverse extensions and a mass flow inside, in the zero- β plasma ...

Novel hybrid bobbin tool friction stir welding of AA2219 with comparison to existing bobbin tool variants

Advances in Industrial and Manufacturing Engineering
Bobbin tool friction stir welding (BT-FSW) is a solid-state joining technique that produces high-strength welds without the need for backing plates. This study introduces a new variant, termed hybrid bobbin tool friction stir welding (HBT-FSW), which ...

Parametric Optimization Of Fsw Of Pp

İlköğretim Online, 2023
Thermoplastics are higher in demand in the era of the advancing technology. Thermoplastic material is very useful in almost every field. Friction stir welding is a solid-stateprocess of joining the thermoplastic polymer. In this situation, attempts were made to joining the polypropylene plate of 6mm thickness with a conical threaded tool pin.

A model of Senegalese FSWs

A model of Senegalese FSWs
application/pdf IDP000677_001 Sex workers supply sex acts out of bare necessity for survival. They are often stigmatised of their profession and worry about being known to others. Effectiveness of registration policies that intend to reduce harms of sexually transmitted infections may be reduced by such stigma.
