ap-958	Blanik, N.; Hülsbusch, M.; Herzog, M.; Blazek, C. R.	Assessment of Human Hemodynamics under Hyper- and Microgravity: Results of two Aachen University Parabolic Flight Experiments	2007	4	.pdf	application/pdf	1749	96	61	7: Different kinetics of blood volume shifts of three sub- jects (measuring points on the forehead using a green (1) and an infrared light source (2), normalized at start of measurement) Fig. 8: Statistical analysis of skin blood volume changes measured with PPG sensors on subjects’ foreheads Acknowledgments To research these dynamic behaviors, the subjects were exposed to a rapid change of gravity (between zero and 1.8 times the normal gravitational force on earth, i.e. 0 g and 1.8 g, respectively) on parabolic flights.	cache/ap-958.pdf	txt/ap-958.txt
