  • Modeling of the thermal behavior of irradiated sphere-pac mixed carbide fuel

    Creator:
    Ades, Maurice
    Abstract:
    Several fuels are being investigated for fast breeder reactor applications. One promising concept is sphere-pac mixed carbide fuel. As a part of the development of this fuel concept it is necessary to determine the behavior of the irradiated fuel for safe and reliable operation on a sound economic basis. It...

  • A model for the mechanical behavior of irradiated mixed carbide sphere pac fuel pins

    Creator:
    George, Thomas L.
    Abstract:
    A model is developed that allows the prediction of the stress-strain distribution in a mixed carbide sphere pac fuel pin during irradiation. The model is coupled with a previously developed model for the thermal behavior of the pin. The one-dimensional (radial at various axial locations) solution is for quasi-steady pin...

  • Dose to the female breast from nuclear medicine and diagnostic radiology

    Creator:
    Patel, Aarti
    Abstract:
    There has been increased concern about radiation dose to the female breasts, with approximately 200,000 new breast cancers being diagnosed each year in the United States. The unprecedented increase in the use of radiologic exams on younger women has also raised some additional concerns about how procedures are performed. The...

  • The effects of gamma radiation on Cascade hop

    Creator:
    Getty, Brooke
    Abstract:
    This gamma irradiation study was conducted to establish an LD50 of the hop (Humulus lupulus L.) cultivar Cascade . The overall, long term goal is to generate replacement hop cultivars by inducing minor but significant DNA alterations with gamma radiation to improve agronomic quality without changing the brewing profile. The...

  • Ultraviolet radiation as an environmental stressor of amphibians

    Creator:
    Bancroft, Betsy A.
    Abstract:
    My thesis explored the effects of and potential mediating mechanisms for an important environmental stressor, ultraviolet-B (UVB) radiation. UVB radiation has negative effects on organisms in both terrestrial and aquatic systems. I used meta-analysis to quantify the effects of UVB radiation on a diversity of aquatic organisms (Chapter 2). UVB...

  • The site of action of radio-lethal compounds on Micrococcus radiodurans

    Creator:
    Manes, Jasper Damon, Jr.
    Abstract:
    Iodoacetic acid and diphenylamine were used in this study to elucidate the mechanisms of resistance of Micrococcus radiodurans to radiation. This organism, a gram positive, non-spore forming, salmon-pink, tetracoccus has a LD₅₀ of 213,000 R when grown in the absence of radio-modifying agents. M. radiodurans, when grown in media containing...

  • A comparison of radiation induced lipid changes in Micrococcus radiodurans, Sarcina lutea, and Pseudomonas aeruginosa

    Creator:
    Ley, Ronald Douglas
    Abstract:
    Quantity variations in pigments and lipid classes were determined following γ-irradiation of Micrococcus radiodurans, Sarcina lutea, and Pseudomonas aeruginosa. Pigmentation was determined by extraction with organic solvents and measured as optical density at 475 mμ for M. radiodurans and S. lutea, and 410 mμ for Ps. E aetuginosa. Pigments of...

  • Design techniques for radiation hardened-phase locked loops

    Creator:
    Nemmani, Anantha Nag
    Abstract:
    Spacecrafts experience radiation in the course of their operation and all electronic equipment on board these spacecrafts has to be designed to withstand the effects of this radiation. This thesis describes the effects of total ionization dose (TID) and single event transients (SET) in phase-locked loops - an important circuit...
