Abstract: Disclosed is a face mask for use with a sports helmet. The face mask comprises a frame which is sized and shaped to surround at least a portion of the face of a user, and is connectable to the helmet. A shielding member is connected to the frame, and has a plurality of wires arranged in a grid, which define a plurality of openings therebetween. At least a portion of the wires are made from high tensile strength transparent wires.

Abstract: A novel Bacillus thuringiensis strain deposited at the International Depository Authority of Health Canada in Winnipeg under accession number IDAC010201-5, its crystal gene having the sequence SEQ ID NO: 1 and crystal protein encoded by same having the sequence SEQ ID NO: 2 and uses thereof. More specifically, the present invention is concerned with a novel Bacillus thuringiensis, novel cry31 protoxin and toxin, nucleotide sequences encoding same and anti-cancer therapeutic applications for the toxin.

Abstract: Adiabatic RF pulses are very useful in MRI when precise flip angles are needed. Unfortunately, adiabatic pulses suffer from a long application time and a high SAR. A new concept to modify the usual adiabatic pulse into a “pseudo-adiabatic” pulse having a shorter application time and lower SAR is introduced. For example, a BIR-4 of 32 ms of application time and a relative SAR of 20 will be transformed into a BIR-4-S1 of 1 ms and relative SAR of 1. The new pulse obtained stays insensitive for a large B1 range but loses its slice selectivity to become a 3D pulse. Experimental results are presented to illustrate the sensitivity to B1 and B0.
