Robust and adjustable C-shaped electron vortex beams [PDF]

New Journal of Physics, 2017
Wavefront engineering is an important quantum technology, often applied to the production of states carrying orbital angular momentum (OAM). Here, we demonstrate the design and production of robust C-shaped beam states carrying OAM, in which the usual ...

Assessment of endodontic treatment of c-shaped root canals

SWISS DENTAL JOURNAL SSO – Science and Clinical Topics, 2014
This communication presents the treatment of 15 cases of c-shaped canals in molars and their treatment outcome with two different obturation methods. The data from 901 patients who received root canal treatment in a molar tooth were examined regarding c-shaped root canals, their treatment and their status one year post op.

Drift chamber with a c-shaped frame [PDF]

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2005
We present the construction of a planar drift chamber with wires stretched between two arms of a c-shaped aluminium frame. The special shape of the frame allows to extendthe momentum acceptance of the COSY-11 detection system towards lower momenta without suppressing the high momentum particles.

Management of C-shaped canals: Two case reports

Journal of Orofacial Sciences, 2013
A C-shaped canal with varying configuration is commonly observed in single-rooted mandibular second molars. Cooke and Cox (1979) first documented the C-shaped canal in endodontic literature.
