The aim of this study was to evaluate, using microcomputed tomography (µCT), the frequency of conjoined mesial canals in first and second mandibular molars with a single distal canal. Mandibular first (n = 114) and second molars (n = 114) with matur

The peritectic transition, where δ -ferrite and liquid transform into γ -austenite, is an important aspect of product quality and process control in many ferrous and non-ferrous alloys. Due to the high temperatures at which the transition takes pla

We present the design of a compact battery-powered optical angle sensor, together with the first results obtained using the prototype measuring system. The output of the sensor is proportional to cos 2θ over a full 360°, where θ is the (possibly s

It has been postulated that pethidine may mediate its effects on postanaesthetic shivering (PAS) via kappa-opioid receptors. However, clinical evidence indicates that alfentanil, a pure mu-agonist, may also have beneficial effects on PAS. In order to
