Weißer Stein (Eifel) 2007 the University of Liège executed measurements and found a height of 692 m (TAW, Belgian standard). The altitude meter of Google Earth caused some doubt about Signal de Botrange (694 m TAW) as Belgium's highest point because its vertical reference EGM96 deviates a couple of meters from the German Normalnull and the Belgian TAW, thereby suggesting an altitude of 701 m for the Weißer Stein. An accurate control by the Belgian National Geographic Institute in 2010 showed the Weißer Stein to be at maximum 693.3 m TAW (=691 m NN), with which it differs by less than 1 m
AM-694 AM-694 AM-694 (1-(5-fluoropentyl)-3-(2-iodobenzoyl)indole) is a drug that acts as a potent and selective agonist for the cannabinoid receptor CB. It is used in scientific research for mapping the distribution of CB receptors. No public data about AM-694 metabolism is known. AM-694 has already emerged as a designer drug. AM-694 is an agonist for cannabinoid receptors. Affinities are: with a "K" of 0.08 nM at CB and 18x selectivity over CB with a "K" of 1.44 nM. It is unclear what is responsible for this unusually high CB binding affinity, but it makes the F radiolabelled derivative of AM-694 useful for
