Galvanic Vestibular Stimulation Applied to Flight Training
… in fatalities. Galvanic Vestibular Stimulation (GVS) provides a cost effective and safe way to simulate spatial disorientation and potentially test pilot’s vestibular system prior to aircraft operation. This experiment investigates the use of GVS as an indicator of motion sensitivity and explores …

International biogas applications
… based on volatile solids (VS) yielded 288 LCH4/kgVS, at an organic loading rate (OLR) of 2 kgVS/m3 /d equating to 89% of the biomethane potential test value. When digested at an OLR of 3 kgVS/m3 /d, methane yields decreased due to an accumulation of volatile fatty acids. A biomethane plant in the …
