One of the most important considerations in the acute management of atrial fibrillation is the need for anticoagulation (see the image below). Acute cardioversion for AF carries a risk of thromboembolism unless anticoagulation therapy is initiated prior to the procedure and continued post procedure.
The glass fibers are made of various types of glass depending upon the fiberglass use. These glasses all contain silica or silicate, with varying amounts of oxides of calcium, magnesium, and sometimes boron.
Australian researchers found a way to make fibers from a composite material made of graphene that's stronger than Kevlar. Adding an equal amount of graphene and carbon nanotubes to a polymer produced a super-strong fiber that could be spun into the fabric used to make bulletproof vests. The fibers could also be used to strengthen other materials.
