Int r t des EVC dans le secteur biom dical
In France, EVC (elastomers which can be vulcanised hot) such as silicones, have several advantages for the biomedical sector. They stand up well at temperatures ranging from -50 C to up to 200 C for standard formulas, and from -120 C to 320 C for special formulas. They also are highly safe physiologically, they perform well in terms of elasticity and transparency, and are quite suitable for processing. These silicones can also undergo several sterilisation cycles without significantly modifying their properties. The only disadvantage is that this polymer can by damaged by ionising energy, which weakens the material and changes its colour.

Ralph Ellison's 1,500 page unfinished novel was cut by two-thirds by his literary executor, John F. Callahan. The 354 page 'Juneteenth' includes only four of the eight previously-published extracts. Ellison enthusiasts may not be satisfied with the truncated version of the novel on which Ellison worked for four decades.

Canada's Anglican Journal published a special report that explored lawsuits filed against church-run schools by former students. The story showed how the federal government used native Canadian children for health-related experiments and how many schools were poorly supplied.
