Effects of angular speed in responses of Paramecium tetraurelia to hypergravity [0.03%]
角速度对四膜虫响应高重力影响的实验研究
H Planel,G Richoilley,C Caratero et al.
H Planel et al.
The paper shows the results of investigations carried out in a single cell organism. Paramecium tetraurelia exposed to different gravitational levels. Hypergravity resulted in a decrease in cell growth rate. The responses depend on g level ...

During exercise, heart rate and blood pressure drives can be elicited by receptors situated in the interstitial space of the muscle. It was recently shown that these receptors are sensitive to the local state of hydration: Increased reflex ...
Subjective luminous line perception under changing g-load and body-positions in parabolic flight [0.03%]
抛物线下不同g值变化和体位对人体主观亮线感知的影响
K Hofstetter-Degen,J Wetzig,J Kass et al.
K Hofstetter-Degen et al.
Five healthy subjects were subjected to parabolic flight with laterally tilted head, trunk, or body position. A vertical luminous line was viewed by the subjects in a head-fixed goggle device. During normal, hyper- and hypogravity phases su...
Parabolic flight as a tool to measure ocular counterrotation in a reduced force environment [0.03%]
抛物线飞行在减少力环境下作为测量眼动反向旋转的工具
J Wetzig,K Hofstetter-Degen,J R Kass et al.
J Wetzig et al.
Five unmedicated subjects were flown in parabolic flight. The aircraft, a Caravelle, performed single parabolae every 2 to four minutes. This resulted in alternating phases of normal, hyper-, hypo- and again hyper-gravity. Subjects sat yoga...
First use of cognitive algorithms in investigations under compensated gravity [0.03%]
