Abstract: The present disclosure relates to the technical field of medical appliances, and provides a dental handpiece and a head thereof, and a root canal preparation machine. The head of the dental handpiece comprises a head housing; a movement cavity is provided in the head housing; a rotatable movement and a driving gear are provided in the movement cavity; the driving gear is sleeved on one end of the movement, and the movement can move along the axial direction of the driving gear; a reciprocating driving mechanism is further provided in the movement cavity, and the reciprocating driving mechanism is used for driving the movement to perform reciprocating movement along its own axis.

Abstract: Provided are an intermetallic compound having high stability and high activity, and a catalyst using the same. A hydrogen storage/release material containing an intermetallic compound represented by formula (1): RTX . . . (1) wherein R represents a lanthanoid element, T represents a transition metal in period 4 or period 5 in the periodic table, and X represents Si, Al or Ge.

Abstract: Systems and methods that incorporate fuzzing capabilities within an SQL server to facilitate penetration testing. A fuzzing component associated with the SQL server provides an entry point for accessing the fuzzing system to update explicit user specified parameters associated with SQL, wherein the server's in depth knowledge regarding semantics of the language code (e.g., manner of parsing) can be employed to determine vulnerabilities thereof.

Abstract: An automation infrastructure which automatically analyzes software faults and/or bugs related to a product defect is provided. More particularly, the system can automatically analyze and detect symptoms in the forms of crash dump, memory leak, corruption and test issues etc. In accordance therewith, aspects can automatically search for and locate existing defect reports, if such existing reports are available. Moreover, aspects can automatically report new defects in a defect tracking database or other tracking mechanism.
