The role of pyridoxine as a countermeasure for in-flight loss of lean body mass [PDF]

open access: yes
Ground based and in flight research has shown that humans, under conditions of microgravity, sustain a loss of lean body tissue (protein) and changes in several biological processes including, reductions in red blood cell mass, and neurotransmitters. The

Reliability of a Shuttle reaction timer [PDF]

open access: yes
Reaction, movement, and task times refer to the times needed to initially respond to a stimulus, make the specific movement, and complete the entire task.

On Simulating Concurrent Flame Spread in Reduced Gravity by Reducing Ambient Pressure [PDF]

open access: yes
The flammability of combustible materials in spacecraft environments is of importance for fire safety applications because the environmental conditions can greatly differ from those on earth, and a fire in a spacecraft could be catastrophic.

Experiment K-6-03. Gravity and skeletal growth, part 1. Part 2: Morphology and histochemistry of bone cells and vasculature of the tibia; Part 3: Nuclear volume analysis of osteoblast histogenesis in periodontal ligament cells; Part 4: Intervertebral disc swelling pressure associated with microgravity [PDF]

open access: yes
Bone area, bone electrophysiology, bone vascularity, osteoblast morphology, and osteoblast histogenesis were studied in rats associated with Cosmos 1887.

Simulation of fluid flows during growth of organic crystals in microgravity [PDF]

open access: yes
Several counter diffusion type crystal growth experiments were conducted in space. Improvements in crystal size and quality are attributed to reduced natural convection in the microgravity environment.

Exobiology and life science [PDF]

open access: yes
The following types of experiments for a proposed Space Station Microgravity Particle Research Facility are described: (1) biogenic elements in the interstellar medium; (2) organic material in the solar nebula; (3) volatiles in comets and icy ...
