|
 | Theiler's murine encephalomyelitis virus (TMEV) is a picornavirus that is used as an animal model for the study of multiple sclerosis (MS). One of the current therapies for MS involves the administration of a type I interferon, IFN-beta. The administration of IFN-beta can result in unfavored, psychological side-effects including clinical depression. A second type I interferon, ovine IFN-tau, has previously been found to be less cytotoxic than IFN-beta. This study ... |

|
| The collision of atomic nuclei traveling at or near relativistic speeds with stationary target nuclei produces a shower of nuclear fragments in all directions and at a wide range of energies, including energies significantly higher than those of the original projectile. Sources of these high-energy projectile nuclei include space radiation of cosmic or solar origin, accelerators, and radiation beams used in medical treatment. Of particular concern is the production of ... |

|
| Although reactive oxygen intermediates (ROI) fulfill physiological roles e.g., intracellular signaling and protection against microbes, sustained ROI levels result in oxidative stress and its deleterious sequelae e.g., DNA mutations to include transmissions and translations (Wink, et al., 1998). Consequently, aberrant antioxidant enzyme function has been speculated to be a key contributor in carcinogenesis. Levels of superoxide dismutase (SOD), the antioxidant enzyme responsible for the dismutation of superoxide to hydrogen peroxide ... |

| The rapid increase in attacks on computer systems has made intrusion detection systems (IDSs) increasingly popular. An emerging research area involves using mobile agents in implementing such systems. The lack of security for mobile agents is a primary factor that has inhibited their widespread use in real-world applications, including intrusion detection systems. Thus, providing security for mobile agents is key to building useful applications based on the mobile agent paradigm. ... |

| Personnel who fight wildland fires are limited to the amount of protective equipment that they can carry with them. Bulky respiratory protection devices are considered extraneous to a smoke jumper who must carry all their tools and living necessities on their backs. In addition, respirators cannot filter out carbon monoxide, a significant airborne hazard from wildland fires.

|
| Orthodontic studies over several decades have found generally inconsistent agreement among dentists when evaluating orthodontic treatment need. There have also been recent reports that undergraduate dental education does not sufficiently prepare dentists to diagnose and make appropriate referrals of potential orthodontic patients. This highlights an opportunity to improve dental education in the area of orthodontic needs assessment. The Index of Orthodontic Treatment Need (IOTN) is an occlusal index that has ... |

Stephen M. Russell; AIR FORCE INST OF TECH WRIGHT-PATTERSONAFB OH
|
| The ability to engineer novel quasi-phase-matched (QPM) structures in bulk periodically poled ferroelectric crystals has led to the development of a wide variety of innovative QPM devices. Lithium niobate has been the material of choice in many of these devices due to its large nonlinear coefficient (d33 ^ 27 pm/V), low cost, and wide availability. However, its large coercive field (^ 2 1 kV/mm) has limited fabrication of periodically poled ... |

|
| Airborne measurements of six mid-level clouds observed over the Great Plains of the United States in late 1999 and early 2000 are analyzed extensively. All cloud fields are associated with a 500-mb low-pressure center or a potential vorticity maximum, with additional lift provided by upper-level jet streams. Data show that these innocuous looking clouds display complicated microphysical and thermodynamic structures. Five of six cases include mixed- phase conditions in temperatures ... |

Timothy C. Radsick; AIR FORCE INST OF TECH WRIGHT-PATTERSONAFB OH
|
| Continuous fiber ceramic composites show promise for applications in high-temperature oxidizing environments, but their actual use has been limited in part due to unstable non-oxide-based constituents or from inadequate oxide- based ones. A porous mullite/alumina matrix combined with alumina/mullite fiber reinforcement eliminates the need for an interface coating while producing a strong, tough and oxidation resistant composite. In this study, a fiber-matrix prepreg was produced by infiltrating Nextel 720 cloth ... |

| This thesis examines the public choice issues surrounding the ongoing tobacco controversy. From a standard public interest story, the arguments against tobacco suggest the need for a total ban of the product; yet that was never seriously proposed. Thus this thesis seeks to apply public choice principles in search of a more realistic understanding of the actions surrounding tobacco. Various public choice principles are analyzed including interest group behavior, bureaucracy, ... |
