Effects of combined shear and thermal forces on destruction of Microbacterium lacticum

Article Abstract:

Combined shear and thermal forces and their destructive effects on Microbacterium lacticum are discussed. Extrusion was used in the study in a concentrated gelatin inoculated with a heat-resistant isolate of the vegetative bacterial species. Higher shear forces with low water contents and calculated die wall shear stress were strongly correlated with bacterial destruction. Heat did not play a major role in cell destruction. A combination approach, it was thought, might be useful to kill microorganisms. Physical forces might be useful, it was thought, in differentiating between and maybe fractionating organisms.

The feel of wood

Article Abstract:

Some tennis players are discovering that tennis is a better game when played with the traditional wood rackets rather than oversized ones made of metal or composites. Wood rackets are more fun because they require more skill.
