The nature of hydrative changes and cationic shifts in the over-tenderization of beef muscle resulting from irradiation

Creator:: El-Badawi, Ahmed Adel Ismail
Abstract:: The over-tenderization of irradiated-sterilized meat is one of the more important adverse effects resulting from the use of irradiation for the preservation of meat. Although research has been reported on the activity and effect of the inherent proteolytic enzymes of irradiated meat, very little work has been directed toward 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...

Indirect effects of ultraviolet-B radiation on larval amphibians as mediated by food quality and trophic interactions

Creator:: Scheessele, Erin A.
Abstract:: Ultraviolet-B radiation (UVB) is an abiotic stressor in both terrestrial and aquatic systems. The stratospheric ozone layer, depleted due to anthropogenic activities and the cause of elevated UVB at earth's surface over the last four decades, is predicted to recover by 2065. However, UVB levels in aquatic systems may continue...

Significance of pigments in radiation resistance of Micrococcus radiodurans

Creator:: Krabbenhoft, Kenneth Louis
Abstract:: An ecological study of a microorganism similar to that isolated in 1956 and designated as Micrococcus radiodurans indicated that the organism could be isolated from several different environments. By taking advantage of its radio-resistivity, high levels of gamma radiation were used in the isolation procedures to inactivate most of the...

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...

Sublethal effects of UV-B radiation on larval amphibians

Creator:: Belden, Lisa K.
Abstract:: Ultraviolet-B radiation (UV-B) has been suggested as a factor contributing to global amphibian population declines. While ambient UV-B levels damage the eggs and embryos of some amphibian species, few studies have addressed how UV-B affects other life history stages or sublethal responses. My dissertation focuses on (1) investigations of sublethal...

Radiation effects in III-V semiconductors and heterojunction bipolar transistors

Creator:: Shatalov, Alexei
Abstract:: The electron, gamma and neutron radiation degradation of III-V semiconductors and heterojunction bipolar transistors (HBTs) is investigated in this thesis. Particular attention is paid to InP and InGaAs materials and InP/InGaAs abrupt single HBTs (SHBTs). Complete process sequences for fabrication of InP/InGaAs HBTs are developed and subsequently employed to produce...

Effects of ultraviolet-B radiation on marine phytoplankton

Creator:: Behrenfeld, Michael Joseph
Abstract:: Global increases in ultraviolet-B radiation (UVBR:290- 320 nm) resulting from decreases in stratospheric ozone concentration have the potential to alter marine primary production and affect global climate and marine trophic dynamics. Effects of UVBR on phytoplankton carbon fixation were determined from open ocean exposure studies conducted off the coast of...
