Artificial gravity as a countermeasure for mitigating physiological deconditioning during long-duration space missions

Frontiers in Systems Neuroscience, 2015
In spite of the experience gained in human space flight since Yuri Gagarin’s historical flight in 1961, there has yet to be identified a completely effective countermeasure for mitigating the effects of weightlessness on humans. Were astronauts to embark

ARTIFICIAL GRAVITY AND ITS IMPLICATIONS

INTERANTIONAL JOURNAL OF SCIENTIFIC RESEARCH IN ENGINEERING AND MANAGEMENT, 2022
Artificial gravity has been one of the interesting topics in modern physics. Let’s take the step deeper and look at some of the physics, both known and experimental, that physicists are analyzing this very moment to improve future space technology. In this article let us discuss how the artificial gravity differs from normal gravity, different ways to ...

Damage estimation on concrete gravity dams through artificial accelerograms

MATEC Web of Conferences, 2018
The aim of this paper is to analyse the damage on gravity dams through artificial earthquakes from two methods. The first procedure defines the performance and the response curve of concrete gravity dams using a harmonic function which establishes linear

Quantum Gravity: Has Spacetime Quantum Properties? [PDF]

, 2009
The conceptual incompatibility between General Relativity and Quantum Mechanics is generally seen as a sufficient motivation for the development of a theory of Quantum Gravity. If - so a typical argumentation - Quantum Mechanics gives a universally valid

Whole-body vibration transmission during resistance vibration exercise

Frontiers in Sports and Active Living
IntroductionResistive exercise combined with whole-body vibration (WBV) and short-arm human centrifugation is being considered as a countermeasure to mitigate muscle and bone loss in astronauts during prolonged space missions.

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

Experimental Physiology
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.

Research on the Placement Error of Artificial Fish Reef in Tianjin Marine Ranching

Haiyang Kaifa yu guanli, 2023
Reasonable artificial reef layout can provide suitable habitat, promote species diversity and ecosystem stability. However, affected by various factors, the actual location of the artificial reef may be different from the plan, resulting in the failure ...
