			Hi Brian, 
		
		
		
		
		
		
		
	Thanks for the pointers! Please give the full reference - maybe others can make xerox copies more easily... Regards, Kai  |

			hi kai, 
		
		
		
		
		
		
		
	ok, i will try. i have to backtrack my thinking process at the time as i found this article in a book, which i found by looking for another book (if you know what i mean - i spend a lot of my time searching through obscure bibliographies) will post the full reference when i can find it. from memory it was a very obsure reference so may not be easy to find.  |
