Theoretical Research Progress in High-Velocity/Hypervelocity Impact on Semi-Infinite Targets
Shock and Vibration, 2015 With the hypervelocity kinetic weapon and hypersonic cruise missiles research projects being carried out, the damage mechanism for high-velocity/hypervelocity projectile impact on semi-infinite targets has become the research keystone in impact dynamics.

Structural Concrete, EarlyView.Abstract Currently, a wider development of modern concrete mixes in the construction industry is expected, such as concretes with alternative cement types and binders, recycled aggregates, but also concretes with dispersed fiber reinforcement to speed up our work in cutting greenhouse gases and making buildings last longer.

Clinical periodontal diagnosis
Periodontology 2000, EarlyView., 2023 Abstract Periodontal diseases include pathological conditions elicited by the presence of bacterial biofilms leading to a host response. In the diagnostic process, clinical signs such as bleeding on probing, development of periodontal pockets and gingival recessions, furcation involvement and presence of radiographic bone loss should be assessed prior ...

Mass mortality and extraterrestrial impacts [PDF]
The discovery of iridium enrichment at the Cretaceous/Tertiary boundary resulted in formulation of hypothesis of a cometary or asteroid impact as the cause of the biological extinctions at this boundary. Subsequent discoveries of geochemical anomalies at

Impact crater morphology and the structure of Europa's ice shell
, 2017 We performed numerical simulations of impact crater formation on Europa to infer the thickness and structure of its ice shell. The simulations were performed using iSALE to test both the conductive ice shell over ocean and the conductive lid over warm ...

Ultrasonographic features of gastrointestinal ulcerations in cats
Veterinary Record, EarlyView.Abstract Background Gastrointestinal ulceration in cats can be life threatening due to the risk of perforation and septic peritonitis. However, the ultrasound findings associated with this condition and their diagnostic sensitivities have not been described.
