Effects of Sex and Gender on Adaptation to Space: Musculoskeletal Health [PDF]
, 2014 There is considerable variability among individuals in musculoskeletal response to long-duration spaceflight. The specific origin of the individual variability is unknown but is almost certainly influenced by the details of other mission conditions such ...

Plasmakristall‐4 Experiment: 10 Years of Operation in Orbit
Contributions to Plasma Physics, EarlyView.ABSTRACT Plasmakristall‐4 (PK‐4) is a microgravity complex plasma laboratory operated for 10 years on board the International Space Station. Its main purpose is the particle‐resolved investigation of generic condensed matter phenomena using strongly coupled suspensions of microparticles immersed in low‐pressure gas‐discharge plasmas.

Monitoring Three-Dimensional Packings in Microgravity [PDF]
, 2013 We present results from experiments with granular packings in three dimensions in microgravity as realized on parabolic flights. Two different techniques are employed to monitor the inside of the packings during compaction: (1) X-ray radiography is used ...

Experimental Factors and Techniques for Pool Boiling Heat Transfer Enhancement: A Critical Review
Heat Transfer, EarlyView.ABSTRACT This review presents a comprehensive assessment of active strategies for enhancing pool boiling heat transfer, with a focus on techniques that do not rely solely on the boiling surface modification. It examines a broad range of methodologies including fluid additives, external fields, mechanical interventions, and thermal‐geometric tuning that

Simulated microgravity compromises mouse oocyte maturation by disrupting meiotic spindle organization and inducing cytoplasmic blebbing. [PDF]
PLoS ONE, 2011 In the present study, we discovered that mouse oocyte maturation was inhibited by simulated microgravity via disturbing spindle organization. We cultured mouse oocytes under microgravity condition simulated by NASA's rotary cell culture system, examined ...

Revista Brasileira de Ensino de Física, 2016 Some experimental activities of low cost and easy accomplishment are proposed to reproduce the microgravity environment that exists in space ships, free fall towers and parabolic flights. The objective is to provide didactical material to aid teachers in terms of assembling instructions, besides the implementation of these experiments and explanation ...
