F wave. In neuroscience, an F wave is the second of two voltage changes observed after electrical stimulation is applied to the skin surface above the distal region of a nerve. F waves are often used to measure nerve conduction velocity, and are particularly useful for evaluating conduction problems in the proximal region of nerves (i.e., portions of nerves near the spinal cord).
The success of the first permanent bobsleigh, luge, and skeleton track in KÃ¶nigssee, West Germany, completed in 1968 and first used for the world luge championships the following year, also played a factor. [7] [8] In 1969, it was decided to construct a permanent facility in Oberhof. [9]
Snowboarding was one of the sports represented at the first-ever Winter X Games in 1997. A year later, it made its Olympic debut at the 1998 Nagano Games, with halfpipe and giant slalom contested. Snowboard cross was added to the Olympic program in 2006, slopestyle premiered in 2014, and big air will make its Olympic debut in PyeongChang.
