The University of Manitoba faculty of dentistry began efforts over a decade ago to integrate the most up-to-date dental education technologies into its preclinical laboratory environment. The faculty now houses 2 modern preclinical laboratories and a dental simulation laboratory that all use high-tech equipment to promote learning. The mix of technologies and equipment found within these labora...
An effective heat dissipation of uncooled 400-Gbps (16×25-Gbps) form-factor pluggable (CDFP) optical transceiver module employing chip-on-board multimode 25-Gbps vertical-surface-emitting-laser (VCSEL) and 25-Gbps photodiode (PD) arrays mounted on a brass metal core embedded within a printed circuit board (PCB) is proposed and demonstrated. This new scheme of the hollow PCB filling with thermal...
The dezincification of brasses has been the subject of substantial conjecture and investigation over the past century and the technical press is littered with papers on the problem. Very broadly the technical literature can be subdivided into five main groups as follows: (a) Observations of dezincification phenomena including mechanically induced dezincification and in-service experience in var...
An investigation of the electrochemical noise generation during Stress Corrosion Cracking (SCC) of 70-30 Brass in Mattson's solution was conducted. The fluctuations of potential and current were monitored. The relationship between potential and current fluctuations has been evaluated in time domain and the obtained data has been analyzed in the frequency domain using Power Spectral Density (PSD...
The evolution of microstructure and texture during isochronal annealing of a heavily cold rolled Al–0.3% Cu alloy has been characterized using electron backscatter diffraction. It is found that the rolling texture of this alloy is dominated by the Brass component and that recrystallization during annealing leads to the formation of a pronounced Goss texture. It is suggested that the development...
