Bond behavior between concrete and steel rebars for stressed elements

Ain Shams Engineering Journal, 2021
Earlier research efforts related to concrete-to-steel rebar bond behavior predominantly focused on common parameters such as concrete strength, rebar diameter, bonded length and concrete cover, disregarding the actual/real state of concrete that ...

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Spatiotemporal and quantitative analyses of phosphoinositides – fluorescent probe—and mass spectrometry‐based approaches

FEBS Letters, EarlyView.
Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

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.

Electromagnetic Stressing of Bonded Structures

, 1993
New nondestructive techniques are being sought to detect and characterize defects in aging aircraft structures. One problem of particular concern is the inspection of bonded and riveted lap joints between aluminum alloy sheets comprising the aircraft’s external skin.
