An Empirical and Subjective Model of Upper Extremity Fatigue Under Hypogravity
Frontiers in Physiology, 2022 In the context of extra-terrestrial missions, the effects of hypogravity (0 < G < 1) on the human body can reduce the well-being of the crew, cause musculoskeletal problems and affect their ability to perform tasks, especially during long-term ...

Solving 2-D gravity inversion problems using a PDE model in geophysics exploration [PDF]
International Journal of Mining and Geo-Engineering, 2022 Inverse modeling is one of the useful solutions to create a logical model with relationships between observed and measured values. In geophysical and subsurface investigations such as cavities or mineral explorations, solving inverse problems using ...

Effects of Partial Gravity on the Function and Particle Handling of the Human Lung. [PDF]
Curr Pathobiol Rep, 2018 The challenges presented to the lung by the space environment are the effects of prolonged absence of gravity, the challenges of decompression stress associated with spacewalking, and the changes in the deposition of inhaled particulate matter.Although there are substantial changes in the function of the lung in partial gravity, the lung is largely ...

Looking for partially-massless gravity [PDF]
Journal of High Energy Physics, 2019 AbstractWe study the possibility for a unitary theory of partially-massless (PM) spin-two field interacting with Gravity in arbitrary dimensions. We show that the gauge and parity invariant interaction of PM spin two particles requires the inclusion of specific massive spin-two fields and leads to a reconstruction of Conformal Gravity, or multiple ...

Partially massless theory as a quantum gravity candidate [PDF]
International Journal of Modern Physics A, 2021 We study partially massless gravity theory (PM gravity theory) and suggest an alternative way to add higher order interaction vertices to the theory. Rather than introducing self-interaction vertices of the gravitational fields to the partially massless gravity action, we consider interactions with matter fields, since it is well known that addition ...

Mathematics, 2023 The gravity force of a gravity field generated by a non-rotating level ellipsoid of revolution enclosing mass M is given as a solution of a partial differential equation along with a boundary condition of Dirichlet type. The partial differential equation

Frontiers in Astronomy and Space Sciences, 2021 Plants are a necessary component of any system of bioregenerative life-support for human space exploration. For this purpose, plants must be capable of surviving and adapting to gravity levels different from the Earth gravity, namely microgravity, as it ...

Life, 2014 The ability to maintain the body relative to the external environment is important for adaptation to altered gravity. However, the physiological limits for adaptation or the disruption of body orientation are not known.

A Moderate Daily Dose of Resveratrol Mitigates Muscle Deconditioning in a Martian Gravity Analog
Frontiers in Physiology, 2019 While there is a relatively good understanding of the effects of microgravity on human physiology based on five decades of experience, the physiological consequences of partial gravity remain far less well understood.
