Behavior of Damaged Reinforced Concrete Beams Strengthened with Externally Bonded Steel Plate

Tikrit Journal of Engineering Sciences, 2013
Flexural strength and deformation of reinforced concrete beams strengthened with steel plates were studied in this paper. For bonding the steel plate to the beam a technique of welding steel plate to the stirrups was followed. Fifteen beams were cast and

Repairing and Strengthening of Box-Section RC Beams Reinforced by GFRP Bars Using Epoxy Injection and GFRP Strips

International Journal of Concrete Structures and Materials
Glass-fiber-reinforced polymer (GFRP) bars are widely applied due to their advantages over reinforcement steel bars. GFRP bars are the main adhesive reinforcement since they have a high strength capacity and corrosion resistance.

Flexural Strengthening of Reinforced Concrete Beams with Substandard Tension Lap Splices Using a Novel Pre-stressing Technique

International Journal of Concrete Structures and Materials
Sudden failure of reinforced concrete (RC) beams with substandard tension lap splices due to low resistance to flexure is a critical issue that needs to be addressed. Accordingly, a novel pre-stressing technique is presented in this paper, which offers a

Phosphorylation‐Facilitated CKB Lactylation At K11 By GCN5 Enhances Creatine Kinase Activity and Mitigates Neuronal Damage After Cerebral Ischemia‐Reperfusion

Advanced Science, EarlyView.
This study uncovers hierarchical coordination between K11 lactylation and S199 phosphorylation of CKB in cerebral ischemia‐reperfusion injury. Such dual modifications potentiate CKB enzymatic function, remodel energy metabolism, alleviate oxidative stress and neuronal damage, and represent a viable therapeutic target for stroke treatment.

Fine‐Tuned Regulation of mRNA Translation and Transport by STAU2 Condensate Facilitates Neuronal Development and Plasticity

Advanced Science, EarlyView.
STAU2 undergoes phase separation to form dynamic condensates that package target mRNAs and deliver them to the distal ends of growing neuronal dendrites. STAU2 condensates stabilize embedded mRNAs and repress their translation. Synaptic activity bidirectionally remodels STAU2 condensates, coordinating local translation of STAU2‐associated mRNAs ...
