Ocr carbon dating inc
Oxidizable carbon ratio dating is a method of dating in archaeology and earth science that can be used to derive or estimate the age of soil and sediment samples up to 35,000 years old.
Fullen's study of the Sarah Peralta site in Louisiana found that the OCR method served as an effective means of inferring time at the site, in the absence of radiometrically dateable charcoal.
Added to the carbon and of equal importance is the resin, which is used for holding the carbon sheets together.
A first for Giant, it contains nano-particles, which in effect means carbon has been ground up and added to the resin, much like a hi-tech aggregate.
For the first time Giant has applied ONS to the standard TCR, whereas previously the tubes were round. 07 model is said to be 10 per cent lighter and five per cent stiffer.
A great deal of effort has gone into redesigning the head tube as well ? In theory the use of carbon-fibre will reduce weight by five per cent and will also increase shock absorption.
06 TCR Advanced, but plenty of changes have been made, making it an evolution of last year? At the heart of the frame, the carbon matrix has been altered.
