Abstract: A method for operating a line-side fundamental-frequency-clocked converter is disclosed. The converters has a bridge circuit with, for example three, upper and, for example three, lower semiconductor switches, which are connected to respective positive and negative terminals of a DC link circuit. Center taps of connected pairs of the upper and lower semiconductor switches are connected to the line voltage phases. Two upper or two lower semiconductor switches are simultaneously activated during fundamental frequency operation for a predetermined time period before or after a natural trigger instant of the semiconductor switches caused by a line voltage angle. An estimated line voltage angle for clocking the semiconductor switches is tracked based on two phase currents measured while the two upper or two lower semiconductor switches are simultaneously active.

Abstract: The invention pertains to novel cyclin dependent kinase inhibitors (cdks) and specifically, but not exclusively, as inhibitors of cdk/cyclin complexes. As described herein, the inhibitors of this invention are capable of inhibiting the cell-cycle machinery and consequently may be useful in modulating cell-cycle progression, ultimately controlling cell growth and differentiation. Such compounds would be useful for treating subjects having disorders associated with excessive cell proliferation.

Abstract: A process for producing a dental prosthesis includes producing a wax prosthesis including artificial teeth and a receiving bed for articulating the artificial teeth by inserting the artificial teeth into the receiving bed at anatomically correct positions, producing a negative mold of the wax prosthesis using a duplicating medium, removing the receiving bed, introducing a fixing material into the negative mold, and allowing the fixing material to set, so that the undersides of the artificial teeth are permanently embedded in the fixing material. The artificial teeth have a holding groove running in a mesio-distal direction on its underside, so as to produce reliable positively locking joining of the artificial tooth to the receiving bed of the wax prosthesis.
