Bone Strength Changes in Rats Exposed to Proton Radiation
Once outside the Earth’s magnetic field astronauts are exposed to a range of particles that can alter their biological makeup. Exposure to radiation has been shown to increase bone porosity and thus an increased fracture ...
Combined Effects of Hind-Limb Suspension and Immobilization on Bone Fracture Mechanics
Scientists around the world are working to address not only how to get to Mars, but also how to make it possible for humans to safely make the journey and live on Mars. Microgravity environments, outside of Earth’s ...
The Effects of 4-He Radiation on the Material Properties of Bone
NASA has a long-term goal to go to Mars. The long duration spaceflight has many risks to astronaut health, including the risk of bone loss due to the absence of gravity and exposure to space radiation. There have been ...
Nano-CT Image Processing of Intramuscular Bone in Herring
This study investigated how to implement image processing techniques to convert large compressed files to enhanced digital images and 3D models that can be visualized and operated on by FEA and other mechanical modeling ...
Bone microstructural changes in rat tibias exposed to space radiation
Human health outside of the Earth’s atmosphere has become a greater concern as humans have lived on the International Space station for over 20 years. Radiation poses a risk to astronaut health, yet there is little research ...
Nano-CT image processing and micromechanical modeling of intermuscular bone in herring
Intermuscular bone is a type of bone unique to teleosts such as North Atlantic herring. It is formed by the intramembranous ossification of myoseptal tendons, which makes it less cartilaginous in nature. The combinations ...
Effect of galactic cosmic radiation on bone microstructural strength
NASA has been looking into new technology for long duration space flight to Mars. Space travel has many unknowns and dangers that are both visible and invisible. Once outside of Earth's radiation shielding atmosphere, ...
Effects of galactic cosmic radiation on material properties of bone
One of the many missions of NASA is to develop a safer agent of space travel for astronauts. According to NASA, the average astronaut will be exposed to anywhere between 50 and 2,000 mGy of effective radiation. In a more ...
The effect of helium ion radiation on the material properties of bone
