Welding deformation analysis based on improved equivalent strain method to cover external constraint during cooling stage

International Journal of Naval Architecture and Ocean Engineering, 2015
In the present study, external restraints imposed normal to the plate during the cooling stage were determined to be effective for reduction of the angular distortion of butt-welded or fillet-welded plate.

New Concept of Equivalent Inherent Strain for Measuring Axisymmetric Residual Stresses

Journal of Manufacturing Science and Engineering, 1997
A new concept, the equivalent inherent strain gθeq, is proposed for measuring axisymmetric residual stresses, based on the inherent strain theory. gθeq is a parameter obtained by incorporating the radial inherent strain component into the tangential inherent strain component in computing the axially uniform axisymmetric residual stresses.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.
