Quench cooling under reduced gravity [PDF]
Physical Review E, 2013 We report the quench cooling experiments performed with liquid O2 under different levels of gravity simulated with the magnetic gravity compensation. A copper disk is quenched from 270K to 90K. It is found that the cooling time in microgravity is very long in comparison with any other gravity level.

Comparison of Microgravity Analogs to Spaceflight in Studies of Plant Growth and Development
Frontiers in Plant Science, 2019 Life on Earth has evolved under the influence of gravity. This force has played an important role in shaping development and morphology from the molecular level to the whole organism. Although aquatic life experiences reduced gravity effects, land plants

Low-velocity granular drag in reduced gravity [PDF]
Physical Review E, 2011 We probe the dependence of the low velocity drag force in granular materials on the effective gravitational acceleration (geff) through studies of spherical granular materials saturated within fluids of varying density. We vary geff by a factor of 20, and we find that the granular drag is proportional to geff, i.e., that the granular drag follows the ...

(2+1) gravity for higher genus in the polygon model [PDF]
, 2004 We construct explicitly a (12g − 12)-dimensional space P of unconstrained and independent initial data for ’t Hooft’s polygon model of (2+1) gravity for vacuum spacetimes with compact genus-g spacelike slices, for any g ≥ 2.

Aerosol deposition in the human lung in reduced gravity. [PDF]
J Aerosol Med Pulm Drug Deliv, 2014 The deposition of aerosol in the human lung occurs mainly through a combination of inertial impaction, gravitational sedimentation, and diffusion. For 0.5- to 5-μm-diameter particles and resting breathing conditions, the primary mechanism of deposition in the intrathoracic airways is sedimentation, and therefore the fate of these particles is markedly ...

Hamiltonians for Reduced Gravity
, 1997 A generalised canonical formulation of gravity is devised for foliations of spacetime with codimension $n_ge1$. The new formalism retains n-dimensional covariance and is especially suited to 2+2 decompositions of spacetime. It is also possible to use the generalised formalism to obtain boundary contributions to the 3+1 Hamiltonian.
