The cratering record at Uranus: Implications for satellite evolution and the origin of impacting objects [PDF]
The crater size/frequency distributions on the major Uranian satellites show two distinctly different crater populations of different ages. Any hypothesis on the origin of the objects responsible for the period of heavy bombardment must account for the ...

Conservation Biology, EarlyView.Abstract Action‐oriented conservation sciences are crippled by 3 false assumptions. First, although it is recognized in theory that natural and anthropic components of ecosystems are tightly intertwined, in practice, many conservation policies and actions are still based on the assumption that human and nonhuman stakes should be dealt with in deeply ...

Experimental Impacts into Strength-Layered Targets: Ejecta Kinematics [PDF]
AImpact cratering has dominated the evolution and modification of planetary surfaces through-out the history of the solar system. Impact craters can serve as probes to understanding the details of a planetary subsurface; for example, Oberbeck and Quaide,

The scaling of secondary craters [PDF]
Secondary craters are common features around fresh planetary-scale primary impact craters throughout most of the Solar System. They derive from the ejection phase of crater formation, thus secondary scaling relations provide constraints on parameters ...

European Journal of Oral Sciences, EarlyView.Abstract This study evaluated the repair bond strengths of ceramic and hybrid ceramic CAD/CAM restorations following bioactive‐glass, silica‐coated alumina, and aluminum oxide surface treatments. Shear bond strength (SBS) tests, surface roughness, and scanning electron microscopic (SEM) evaluations were performed on 180 specimens (7×12×2 mm3 and 5×5×3 ...

Simulated meteorite impacts and volcanic explosions: Ejecta analyses and planetary implications [PDF]
Past cratering studies have focused primarily on crater morphology. However, important questions remain about the nature of crater deposits. Phenomena that need to be studied include the distribution of shock effects in crater deposits and crater walls ...
