Another proposal is that countries should prepare " transparency reports " on their implementation of the various standards , and in the first experimental round , three countries - - Argentina , Australia , and the United Kingdom - - have volunteered such reports . But in 1995 , researchers at Ames Laboratory , led by Bruce Harmon , developed a " spin dynamics " computational technique that can be used to accurately represent and evaluate the fluctuations of atomic moments ( magnetic orientations ) in solid magnetic materials at different temperatures . The inks can also spread across the paper at different rates , refered to as their " diffusion constants " . The hill areas had fragmented " pocket economies " with subsistence agriculture and limited economic exchange between different areas in undulating terrain . In Europe the ancient races were all , according to Shaaffhausen , * " lower in the scale than the rudest living savages " ; they must therefore have differed , to a certain extent , from any existing race .
