Personality Traits of People Attracted by Parabolic Flight

Aviation, Space, and Environmental Medicine, 2014
Studies have shown that members of expeditions in extreme environments differed on the basis of personality factors (e.g., they were highly competitive, higher on Extraversion and Conscientiousness) compared to the control population. In order to identify individuals who are likely to participate in extreme environments, the aim of the present study ...

Caloric nystagmus decay during parabolic flight

Acta Oto-Laryngologica, 1990
In human subjects the caloric test was conducted during parabolic flight. The slow-phase velocity (SPV) of the caloric nystagmus increased proportionally to the value of the g-force. The nystagmus disappeared in microgravity, after an exponential SPV decay that showed a specific time constant (Tc).

Changes in cerebral oxygenation during parabolic flight

European Journal of Applied Physiology, 2013
Assessing changes in brain activity under extreme conditions like weightlessness is a desirable, but difficult undertaking. Results from previous studies report specific changes in brain activity connected to an increase or decrease in gravity forces.

Diffusion boundaries behaviour during a parabolic flight

Microgravity - Science and Technology, 2003
The behaviour of a diffusion boundary between distilled water and a 1% sodium chloride solution during a parabolic flight has been observed. The presence of a few percent of Earth gravity pulses during the micro gravity conditions is sufficient to largely perturb the diffusion boundary that stabilises again during the subsequent normal gravity ...

Visually-induced tilt during parabolic flights

Experimental Brain Research, 1990
A helmet-mounted visual display system was used to study visually induced sensations of self-motion (vection) about the roll, pitch and yaw axes under normal gravity condition (1g) and during the microgravity and hypergravity phases of parabolic flights aboard the NASA KC-135 aircraft.

Otolith responses in man during parabolic flight

Experimental Brain Research, 1993
The influence of the varying gravito-inertial (Gz) force during parabolic flight on human otolith function was investigated experimentally. It was hypothesised that a varying Gz force profile initiates an otolith-ocular response that manifests itself in modulation of optokinetic nystagmus slow-phase eye velocity (OKN-SPV).

Gelation of hybrid aerogels in parabolic flights and on the ISS

Microgravity - Science and Technology, 2005
The projects aims to synthesize new functional hybrid aerogels with nonlinear optical properties by incorporation of nano to micron sized particles of piezo-, ferro-, pyro- or photorefractive character into a transparent matrix composed of a nanostructured silica aerogel.

Carotid artery pulsatility during parabolic flights

Acta Astronautica, 1995
In cardio-vascular hemodynamic, the arterial pulsatility, represented by the arterial pulse pressure (PP= systolic blood pressure-diastolic blood pressure), is different from one site to another, in opposite with the mean blood pressure almost identical in the whole body in supine position (or in microgravity). This is due to the arterial tree geometry

Lipoxygenase activity during parabolic flights.

Journal of gravitational physiology : a journal of the International Society for Gravitational Physiology, 2001
Experiments in Space clearly show that various cellular processes, such as growth rates, signaling pathways and gene expression, are modified when cells are placed under conditions of weightlessness. As yet, there is no coherent explanation for these observations, though recent experiments, showing that microtubule self-organization is gravity ...

Parabolic flight experiments with PK-4

Microgravity - Science and Technology, 2006
PK-4 is an experiment designed to investigate complex plasmas (low-temperature plasmas containing microparticles, e.g. dust grains) in a combined dc/rf discharge under microgravity conditions on board of the International Space Station. Within the 35th and 36th ESA parabolic flight campaigns first experiments under microgravity conditions in a ...
