Abstract: A surgical instrument, has an end effector that includes an ultrasonic blade, and a clamp arm that moves relative to the ultrasonic blade from an opened position toward an intermediate position and a closed position. The clamp arm is offset from the ultrasonic blade to define a predetermined gap in the intermediate position between the opened position and the closed position. A clamp arm actuator connects to the clamp arm and moves from an opened configuration to a closed configuration to direct the clamp arm from the opened position toward the intermediate position and the closed position. A spacer connects with the clamp arm to inhibit movement of the clamp arm from the intermediate position toward the closed position for maintaining the predetermined gap between the clamp arm and the ultrasonic blade.

Abstract: A golf training aid designed to give a golfer a multi-sensory practice experience by providing sound, smell and a visual measure of how the club struck the ball at impact. The invention uses cap strips placed in the club face starting with the largest size and then smaller size as accurate as he improves. The device includes using a thin paper body with an array of tiny explosive charges disposed across the surface that includes an adhesive for attaching the invention to the club face while permitting its removal when the shot has been taken. The golfer can visually determine where the ball impacted the club face after the shot. The golfer also hears an explosion at the time of impact along with a olfactory response from the caps exploding. The golf training aid is very inexpensive to use, and the devices can be saved to see the pattern of hitting from the golfer.

Abstract: Dihydroorotate dehydrogenase (DHOD) inhibititon assays are utilized in a method for identifying new fungicides; DHOD inhibitors are useful in fungicidal methods and compositions. Resistance genes that are mutants of the wild-type Aspergillus nidulans dihydroorotate dehydrogenase gene have been isolated and found to impart resistance to certain DHOD inhibitors. The resistance genes are useful as selectable markers in fungi. The wild-type gene is also provided.
