Subungual Epidermoid Inclusions–A Series of 8 Cases and a Review of Literature

open access: yesJournal of Cutaneous Pathology, EarlyView.
ABSTRACT Subungual epidermoid inclusions (SEI) are benign cystic lesions of the nail bed. To our knowledge, there has been only one case series describing SEI. We report eight cases of SEI. The patients had a median age of 72 years (range 3–84) with a female: male ratio of 1.6. Five occurred in toenails and three in fingernails.

The cratering record at Uranus: Implications for satellite evolution and the origin of impacting objects [PDF]

open access: yes
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 ...

Simulated meteorite impacts and volcanic explosions: Ejecta analyses and planetary implications [PDF]

open access: yes
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 ...

Effect of surface conditioning protocols on the repair bond strength of resin composite to CAD/CAM blocks: Bioactive‐glass, silica‐coated alumina, or aluminum oxide?

open access: yesEuropean 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 ...

The scaling of secondary craters [PDF]

open access: yes
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 ...
