Volar Dislocation of Second, Third and Fourth Carpometacarpal Joints in Association with a Bennet's Fracture of the Thumb .

Injuries of the carpometacarpal joints of the long fingers are infrequent and go often unnoticed if a thorough clinical exploration and complete radiological assessment is not carried out. The overall frequency of carpometacarpal joints injuries is of 1-2% among trauma of the wrist and the carpus. These are normally secondary to high energy trauma (such as a car or a motorbike accidents).

Modeling the influence of electron beam irradiation on the heat resistance of Bacillus cereus spores.

The effect of electron beam irradiation (EBI) on Bacillus cereus spore heat resistance was investigated. Irradiation with accelerated electrons had an important heat-sensitizing effect on distilled-water spore suspensions. After irradiation doses of 1.
