Structural Vulnerability in Health Research: A Systematic Mixed Studies Review

Journal of Advanced Nursing, EarlyView.
ABSTRACT Aims To systematically examine how structural vulnerability has been defined and operationalised in United States‐based health research, identify conceptual consistencies and methodological gaps, and propose core dimensions of structural vulnerability along with implications for future application in health research.

Double-sided friction stir welding of 2195 aluminum-lithium alloy

Cailiao gongcheng
Based on the response surface design， the optimal process parameters for single-side friction stir welding（FSW） of 2195 Al-Li alloy sheets are studied. It is found that the higher the rotation speed and the lower the welding speed， the higher the tensile

Studying the WHIM Content of the Galaxy Large-Scale Structures along the Line of Sight to H 2356-309

, 2010
We make use of a 500ks Chandra HRC-S/LETG spectrum of the blazar H2356-309, combined with a lower S/N spectrum of the same target, to search for the presence of warm-hot absorbing gas associated with two Large-Scale Structures (LSSs) crossed by this ...

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 3-mm-thick AA6082-T6 aluminum alloy. A novel ultrasonic system integrated into the tool holder was employed to introduce axial ultrasonic vibrations ...

Metacaspases contribute to the cellular response to heat stress in a marine diatom

New Phytologist, EarlyView.
Summary Climate‐driven marine heatwaves (HW) are extreme, large‐scale events characterized by elevated ocean temperatures lasting from days to months. Despite their importance, little is known about the molecular mechanisms of algal response to marine HW. Recent studies suggest that metacaspases play an important role in thermotolerance.

A comparison between single sided friction stir welded and submerged arc welded DH36 steel thin plate [PDF]

, 2012
The adoption of the friction stir welding (FSW) process into the shipbuilding industry is being considered as a medium term issue. Currently the data on friction stir welded mild steels tends to be fragmented, with critical areas being short on specific ...

The role of substrate materials for the survival and growth of coral micro‐fragment sheets

Restoration Ecology, EarlyView.
Biofouling can have a negative impact on the survival and growth of corals in aquaculture. For coral aquaculture to support reef restoration, there needs to be a cost‐effective and efficient method that reduces the reliance on labor for coral maintenance.

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,

The Effect of Friction Stir Welding Parameters on the Weldability of Aluminum Alloys with Similar and Dissimilar Metals: Review

Metals, 2022
The solid-state welding method known as friction stir welding (FSW) bonds two metallic work parts, whether the same or different, by plastically deforming the base metal.

Overview of the mean of production used for FSW [PDF]

, 2010
The Friction Stir welding process is now introduced in production plants. More and more applications are developed and the most part of the work is now centered on the mean of production to be used.
