Dynamic Strength of Concrete Targets at Impact Interaction with a Spherical Projectile

The dynamic loading of concrete barriers is accompanied by a rapid development of strain and fracture. Consequently, the concrete behavior under the impact differs significantly from its behavior under quasi-static loading. The estimation of the dynamic strength and the developme...

Overt and Occult Hepatitis B in Hemodialysis Patients: Insights from High-Sensitivity Testing and Genetic Analysis

Background/Objectives: Occult hepatitis B infection (OBI) remains a diagnostic challenge, particularly in hemodialysis (HD) patients, who are vulnerable to HBV infection due to immune dysfunction and repeated exposure. Methods: We evaluated the prevalence and molecular characteri...
