An In Vitro Investigation of the Impact of Ultrasound Induced‐Streaming Motions on the Flow Inside Lateral Features of the Root Canal

open access: yesInternational Endodontic Journal, EarlyView.
ABSTRACT Aim The study aims to experimentally characterize the flow inside lateral canals during ultrasonic irrigation. The effect of the canal angle as well as the relative position of the endodontic file with the inlet of the channel was quantified. Methodology An idealized endodontic geometry was 3D printed and used as a mould to fabricate a channel

Modeling enstatite chondrites: Reduced rocks with a pinch of oxidized material (affected by varying H2O(g)) derived from planetesimals shocked during the epoch of giant–planet migration

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract The O‐, N‐, Mo‐, Ru‐, Os‐, Cr‐, Ti‐, Ni‐, Fe‐, Nd‐, Ca‐, Zn‐, Sr‐, and Mg‐isotopic compositions of enstatite chondrites are essentially identical to those of the Earth and Moon. These correspondences suggest enstatite chondrites formed at ≈1 AU as the only known chondrite groups that accreted in the vicinity of a major planet. Bulk Earth has a
