Mitambo, Mitambo M., Zhang, Shuliang L., Loppnow, Glen R.
A novel four nuclear magnetic resonance (NMR)-tube holder is described for quantitative Raman and resonance Raman spectroscopy. This cell has advantages over other divided cell designs in producing high precision quantitation and eliminating off-axis errors. Raman spectra were obtained for both...

Comparison of Deformation and Torque Expression of the Orthos and Orthos Ti Bracket Systems
Download2011
Major, Paul W., Melenka, Garrett W., Carey, Jason P., Nobes, David S., Heo, Giseon, Lacoursiere, Ryan A.
Orthodontic torque expression is the result of axial rotation of rectangular archwires within a rectangular bracket slot. This study investigates the effect of bracket material on torque expression. Torque exerted by a rotating archwire on each bracket will be measured as well as the relative...

Forst, Darren, Nijjar, Simrit, Flores-Mir, Carlos, Carey, Jason, Secanell, Marc, Lagravere, Manuel
The objective of this study is to analyze a set of previously developed and proposed image segmentation protocols for precision in both intra- and inter-rater reliability for in vivo tooth volume measurements using cone-beam computed tomography (CBCT) images. Six 3D volume segmentation procedures...

Friedrich, J., Reime, B., O'Brien, B., Gerrish, K., Bharj, K., Higginbottom, G.M.A., Foster, C., Chowbey, P., Mumtaz, Z., Salway, S.
Background: Public health researchers are increasingly encouraged to establish international collaborations and to undertake cross-national comparative studies. To-date relatively few such studies have addressed migration, ethnicity and health, but their number is growing. While it is clear that...

Archwire rotation is used in orthodontic treatment to alter the labiolingual orientation of a tooth. Measurement of the 3-dimensional (3D) motion of the orthodontic brackets requires a new configuration of the orthodontic torque simulator. The orthodontic torque simulator was coupled with a...

Braces are used by orthodontists to correct the misalignment of teeth in the mouth. Archwire rotation is a particular procedure used to correct tooth inclination. Wire rotation can result in deformation to the orthodontic brackets, and an orthodontic torque simulator has been designed to examine...

In this article, the author challenges the tendency in common law Canada to conflate the distinction between State and society. Following the analysis of Kenneth Dyson, the author contends that the State occupies a distinct sphere produced by or contained in the interconstitutive relationship of...
