Recommended Research on Artificial Gravity [PDF]

open access: yes, 2006
Based on the summaries presented in the above sections of what is still to be learned on the effects of artificial gravity on human functions, this chapter will discuss the short- and long-term steps of research required to understand fundamentals and to

Gender-Specific Cardiovascular Reactions to +Gz Interval Training on a Short Arm Human Centrifuge

open access: yesFrontiers in Physiology, 2018
Cardiovascular deconditioning occurs in astronauts during microgravity exposure, and may lead to post-flight orthostatic intolerance, which is more prevalent in women than men.

Short-Term Cardiovascular Response to Short-Radius Centrifugation With and Without Ergometer Exercise

open access: yesFrontiers in Physiology, 2018
Artificial gravity (AG) has often been proposed as an integrated multi-system countermeasure to physiological deconditioning associated with extended exposure to reduced gravity levels, particularly if combined with exercise.

Is Gravity an Entropic Force? [PDF]

open access: yes, 2011
The remarkable connections between gravity and thermodynamics seem to imply that gravity is not fundamental but emergent, and in particular, as Verlinde suggested, gravity is probably an entropic force.

The philosophy behind quantum gravity [PDF]

open access: yes, 2006
This paper investigates some of the philosophical and conceptual issues raised by the search for a quantum theory of gravity. It is critically discussed whether such a theory is necessary in the first place, and how much would be accomplished if it is ...

Spacetime and the Philosophical Challenge of Quantum Gravity [PDF]

open access: yes, 2001
We survey some philosophical aspects of the search for a quantum theory of gravity, emphasising how quantum gravity throws into doubt the treatment of spacetime common to the two `ingredient theories' (quantum theory and general relativity), as a 4 ...

Experimental study on the effects of artificial vegetation density on forehead of saline

open access: yesAin Shams Engineering Journal, 2016
Gravity current is one of the most important factors in the deposition and reservoirs useful life reducing. The progressive section (forehead of gravity current) is an important part of this process which is influenced by many factors.
