These fibres have very different properties Proof has been very well shown both in determining the chemical composition of the fibres and the level of danger they present Chrysotile should not be classified among amphibole fibres A distinction shoul. A muscle fibre is a long cylindrical muscle cell held together in bundles to make up an individual skeletal muscle. Human skeletal muscles consist of a mixture of each type of muscle fibre. The relative proportion of each fibre type varies in the same muscles of different people e.g. Elite marathon runners have a greater proportion of slow twitch fibres and elite sprinters have more fast twitch fibres.. Fibre Optics. November 2014. Colin G4GBP. The history of fibres. There are references going right back to the Roman times of glass being pulled into strands and being used as ‘light pipes’. Our real interest starts in about 1970 when Corning started doping silica glass and Bell Labs demonstrating that a semi-conductor laser could be used to send signals down the fibres with very low losses. The first practical use of fibre optic cables was by Dorset Police in 1975. Robert P. Nolan, PhD. International Environmental Research Foundation. New York, New York. www.ierfinc.org.

The term Asbestos designates a group of naturally occurring fibrous serpentine or amphibole minerals with historical commercial usefulness due to their extra ordinary tensile strength, poor heat conduction and relative resistance to chemical attack.
