On the Brittleness of Heat-affected Zone (Report 5)
JOURNAL OF THE JAPAN WELDING SOCIETY, 1955 It is recognized that the impact-resistance of sharp-notched specimen decreases suddenly at the so-called "transition temperature". Below this temperature the fracture shows more brittle than shear one and at low temperatures the shear fracture vanishes.

FEBS Open Bio, EarlyView.The two catalytic subunits of typhoid toxin dissociate from the holotoxin in the ER of an intoxicated cell, but only CdtB exits the ER to generate immunosuppressive effects. PltA is retained in the ER and sequestered from its cytosolic target, thus allowing the anti‐inflammatory effects of CdtB to promote intestinal colonization.

Study on the Corrosion Behavior of 7A52 Al Alloy Welded Joint by Electrochemical Method
International Journal of Electrochemical Science, 2013 Twin-wire metal inert gas arc welding (TMW) was used to join the 7A52 Al alloy plates with the ER 5356 filler. The microstructure observation showed that the joint included four zones, i. e., base metal, heat affected zone, fusion zone and weld zone. The

Effect of Grit Blasting and Thermal Spraying on Microstructure Evolution of P91 Weldment [PDF]
Archives of Metallurgy and Materials, 2018 In the present work, studies have been carried out on the variations in the microstructure and hardness of P91 base-metal and welded joint. This variations result from the grit blasting and thermal cycle experienced during the thermal spraying process ...

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objectives Focal cortical dysplasia (FCD) is the most common etiology of drug‐resistant epilepsy in children. Focal to bilateral tonic–clonic seizures (FBTCS) mark a high risk of drug‐resistant epilepsy and involve thalamocortical circuitry in their generation and propagation.
