Dynamic scaling for the growth of non-equilibrium fluctuations during thermophoretic diffusion in microgravity [PDF]

arXiv, 2015
Diffusion processes are widespread in biological and chemical systems, where they play a fundamental role in the exchange of substances at the cellular level and in determining the rate of chemical reactions. Recently, the classical picture that portrays diffusion as random uncorrelated motion of molecules has been revised, when it was shown that giant

Blood flow restriction: The acute effects of body tilting and reduced gravity analogues on limb occlusion pressure

Experimental Physiology, EarlyView.
Abstract Blood flow restriction (BFR) has been identified as a potential countermeasure to mitigate physiological deconditioning during spaceflight. Guidelines recommend that tourniquet pressure be prescribed relative to limb occlusion pressure (LOP); however, it is unclear whether body tilting or reduced gravity analogues influence LOP.

Behavior of a liquid drop in a rounded corner: Different contact angles

AIP Advances, 2019
The Concus-Finn condition, based on the local microscopic contact angle, can be used to predict discontinuous behavior of a liquid drop in an ideally sharp corner.

ATHLETIC: An exoskeleton countermeasure exercise device for resistive and plyometric training in deep‐space missions

Experimental Physiology, EarlyView.
Abstract Prolonged exposure to weightlessness leads to loss of muscle and bone mass. Therefore, astronauts on board the International Space Station (ISS) currently perform mandatory daily exercises. ISS missions usually last 6 months, and future missions will become significantly longer when going, for example, to Mars.

microgravity and nanomaterials

, 2017
Some experiments evidence that Microgravity (Micro-g) has influence in the morphology growth rate of materials and physiology of biological systems. Some Micro-g systems have been developed for experimentation under these conditions. The 2-D, 3-D clinostats and Random Positioning machines stimulate weightlessness.

Microgravity‐induced changes in skeletal muscle and possible countermeasures: What we can learn from bed rest and human space studies

Experimental Physiology, EarlyView.
Abstract Despite exercise countermeasures to sustain health and performance in spaceflight, complete maintenance of muscle mass and functions in microgravity is still not possible for most astronauts. The principal cause of the limited effectiveness of existing exercise countermeasures is the difficulty in achieving full loading forces in space.

Functional and Structural Adaptations of Skeletal Muscle to Microgravity [PDF]

, 2001
Our purpose is to summarize the major effects of space travel on skeletal muscle with particular emphasis on factors that alter function. The primary deleterious changes are muscle atrophy and the associated decline in peak force and power.
