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

Augmentation of alveolar part of mandible with CGF (concentrated growth factors) after multiple extractions – a case report

Journal of Education, Health and Sport, 2018
Concentrated growth factors are one of platelet-rich plasma preparations (PPP), specially prepared in medical centrifuges. Due to high concentration of blood platelets, which reveal different sorts of growth factors, CGF stimulates wound healing, reduces

Centrifugal Etching

Journal of The Electrochemical Society, 2003
A cell consisting of a rotatable double-walled cylinder is described for the study of etching under conditions of enhanced gravity. Rotation rates of 6000 revolutions per minute giving g values of up to 600 were possible with the set-up. The cell was tested by etching masked patterns in a copper plate with an aqueous FeCl3 solution.
