The influence of weightlessness on pharmacokinetics
Fundamental and Clinical Pharmacology, 2005AbstractThe primary hostile factor during a spaceflight is the lack of gravity, which can induce space motion sickness and act on bones, muscles and the cardiovascular system. These physiological effects may modify the pharmacokinetics of the drugs administered during the flight producing reduced pharmacological activity or appearance of adverse ...

Molecular Biological Effects of Weightlessness and Hypergravity on Intervertebral Disc Degeneration.
Aerospace Medicine and Human Performance, 2017INTRODUCTION The rate of intervertebral disc degeneration (IVDD) is influenced by environmental factors. Extracellular matrix (ECM) destruction and apoptosis of intervertebral disc cells are major characteristics of IVDD.

Weightlessness: A Matter of Gravity [PDF]
New England Journal of Medicine, 1977 The advent of space flight has permitted man to leave his accustomed place on the surface of the earth and take the first tentative steps outward into the vastness of the universe.

Illusions of verticality in weightlessness
The Clinical Investigator, 1993In weightlessness most subjects feel themselves, and see the visual surroundings, in either an upright or an upside-down orientation although the gravitational force vector is missing. According to a theory of gravity perception, these illusions of positional and visual verticality are assumed to be caused by the force-independent z-axis bias of ...

Electrostatic demonstration of free-fall weightlessness
, 2015The phenomena of free-fall weightlessness have been demonstrated to students for many years in a number of different ways. The essential basis of all these demonstrations is the fact that in free-falling, gravitationally accelerated systems, the weight ...

Faraday instability in a near-critical fluid under weightlessness.
Physical review. E, Statistical, nonlinear, and soft matter physics, 2014Experiments on near-critical hydrogen have been conducted under magnetic compensation of gravity to investigate the Faraday instability that arises at the liquid-vapor interface under zero-gravity conditions.

Biomechanics in Weightlessness
PAJ: A Journal of Performance and Art, 2002Creation of theatre or any other performance event in weightless conditions opens up the basic issues of physical realities to both the performers and the audience. The spectators, for example, have to be buckled down in order not to fly over to the stage while the dancers, normally studying the arrangement of the balancing points in their bodies ...

The Physics Teacher, 1963
A definition of "weight" becomes more important now that manmade satellites, some with astronauts, revolve about the earth. Does the astronaut become weightless? Definitions and discussion of the terms weight and apparent weight are given. One definition is proposed as the best to use in a physics course.
