      Vander Wiele, Sabrina S.; Felipe, Jack T.; Thomas, Patricia; Davis, Catherine M.; Lau, Anthony G. (2021)
      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 ...
    • Bone Strength Changes in Rats Exposed to Proton Radiation 

      Torres, Gilberto; Davis, Catherine M.; Lau, Anthony G. (2020)
      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 

      Connell, Rosalie; Sanseverino, Matthew; Piserchia, Jennifer; Lau, Anthony G. (2020)
      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 ...
    • Combined Hind Limb Suspension and Srankle on Bone Strength in Mic by Finite Element Analysis: Effects of Anatomic Model Height 

      Lau, Anthony G.; Hezrony, Benjamin; Speacht, Toni; Donahue, Henry J. (2019)
      With commercial space travel on the horizon, it is necessary to understand how the microgravity environment present in space impacts bone in conjunction with the osteoporotic effects of aging. The microgravity environment ...
    • Effect of galactic cosmic radiation on bone microstructural strength 

      Felipe, Jack T.; Vander Wiele, Sabrina S.; Davis, Catherine M.; Lau, Anthony G. (2021)
      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, ...
    • The effect of helium ion radiation on the material properties of bone 

      Thomas, Patricia; Sullivan, Lindsay K.; Dickinson, Gary H.; Davis, Catherine M.; Lau, Anthony G. (Springer, 2021-06)
    • The Effects of 4-He Radiation on the Material Properties of Bone 

      Thomas, Patricia; Davis, Catherine M.; Dickison, Gary H.; Lau, Anthony G. (2020)
      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 ...
    • Effects of galactic cosmic radiation on material properties of bone 

      Meyers, Michelle; Okulicz, Calvin J.; Thomas, Patricia; Davis, Catherine M.; Lau, Anthony G. (2021)
      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 Effects of Head Only Radiation on the Hardness of Bone 

      Lau, Anthony G.; Dickinson, Gary H.; Thomas, Patricia; Davis, Catherine M. (2019)
      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 ...
    • Effects of Helium-4 Radiation on Bone Mechanics 

      Lau, Anthony G.; Connell, Rosalie; Dickinson, Gary H.; Davis, Catherine M. (2019)
      In the 50 years since NASA s first moon landing, space exploration has become more prevalent as the necessity for extraterrestrial resources has increased on Earth. Outside of Earth s magnetic field, there is a lack of ...
    • The effects of hind suspension and casting on bone strength 

      Sanseverino, Matthew; Speacht, Toni; Donahue, Henry J.; Lau, Anthony G. (2017)
      Casting bones is the current method for setting bones after they are broken to dissuade movement and ensure optimal conditions for bone healing. Casting, however, is a cause for concern because bone mineral density can ...
    • Finite element analysis of femoral neck strength losses due to space irradiation 

      Johnson, Dale R.; Lawrence, Summer E.; Livingston, Eric W.; Heinz, Robert D.; Davis, Catherine M.; Lau, Anthony G. (2017)
      Spaceflight leaves astronauts at risk for negative consequences to bone health. Sending a manned mission to Mars is a long term goal of the National Aeronautics and Space Administration (NASA). Because this trip will take ...
    • Long-Time Elastic Modulus of Rat Femurs Exposed to Radiation Using Microindentation 

      Lau, Anthony G.; Okulicz, Calvin J.; Dickinson, Gary H.; Davis, Catherine M. (2019)
      NASA has trips to both the Moon and Mars on their itinerary for the near future. Health and safety of the astronauts is of the upmost importance for the missions. Bone loss, or osteoporosis, is a known risk of space travel ...
    • Modeling space radiation induced bone loss in rat femurs through finite element analysis 

      Borg, Alex; Johnson, Dale; Lawrence, Summer; Livingston, Eric W.; Heinz, Robert D.; Davis, Catherine M.; Lau, Anthony G. (2016)
      Spaceflight leaves astronauts at risk for negative consequences to bone health. A long term mission of NASA has been to send a manned mission to mars. Taking over a month for astronauts to reach Mars, long term effects ...
    • Nano-CT image processing and micromechanical modeling of intermuscular bone in herring 

      Abdelmohsen, Lara; Okulicz, Calvin J.; Hezrony, Benjamin; Peyrin, Francoise; Berteau, Jean-Philippe; Lau, Anthony G. (2021)
      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 ...
