Title: A truncated form of fibrobacter succinogenes 1,3-1,4-beta-d-glucanase with improved enzymatic activity and thermo-tolerance
Inventor: SHYUR LIE-FEN
IPC: C12N9/24
Filed: 2000-12-30
Granted: 2004-05-21
Abstract: A truncated glucanase with an improved thermal stability and a higher specific enzymatic activity than the wild-type enzyme.

Title: Precast joint for plastic hinge zone of vibration-resistant bridge strut
Inventor: MO YI-LUNG
IPC: E01D19/00
Filed: 2001-01-19
Granted: 2002-11-01
Abstract: Disclosed is a precasting joint for the plastic hinge zone of vibration-resistant bridge strut, primarily related to a precasting process aiming towards the reinforced concrete bridge strut and its joint with the bridge bearing. The precasting joint for the plastic hinge zone of vibration-resistant bridge strutting of the present invention is primarily related to embedding the bridge strutting to the bridge bearing that is made by injecting cement concrete at the field. Therefore, the plastic hinge zone may be extended, and the reinforced steel splicing device may be reserved at locations where the horizontal steels on the bridge bearing top are located with the formation of the bridge bearing, so as to serve as affixation for bridge strut segments. Because the precast bridge strut extends into the bearing bottom, and the reinforced steels of the bridge struts are riveted to the horizontal reinforced steels, such a design serves to stabilize the bridge strut and helps to affix the precast strut segments by being spliced to the previously reserved reinforced steels.
