This paper presents a current-source inverter topology that is suitable for multi-megawatt wind turbines. The proposed scheme utilizes two series-connected three-phase inverters that employ fully controllable switches and a proper interconnection transformer with the mains. In order to improve the efficiency and to allow the use of high-power devices, the(More)

Strength in bending was determined for interdental fixation apparatuses applied to hemimandibles obtained from 24 canine cadavers. Hemimandibles were osteotomized perpendicular to the long axis between the third and fourth premolars, and segments were stabilized with 1 of 5 interdental fixation apparatuses: Erich arch bar (EAB, n = 6); Stout loop (SL, n =(More)
A 4.5-month-old Himalayan cat was evaluated because of a cleft secondary palate. Multiple surgical procedures failed to provide soft-tissue coverage of the defect. A 3-cm silastic nasal septal button was trimmed and placed in the oronasal fistula. This prosthodontic appliance provided obturation of the defect without the need for removal or cleaning. Food(More)
