Creator:: McDougall, Melissa Quin
Abstract:: Cognitive impairment, or cognitive decline, a noticeable and measurable decline in cognitive abilities (e.g. memory and learning) that exceeds those attributed to normal aging, represents an early symptom of neurodegeneration and increased risk for progression to more severe dementias, such as Alzheimer's disease (AD). While the complex etiology of these...

Creator:: Shir Mohammadi, Meisam
Abstract:: Today nano scale materials are being used for wide range of applications. One promising topic in nano scale materials is using them for reinforcement of different polymeric materials to reach desirable stiffness properties. The stiffness of these materials is mostly found experimentally because the nanocomposite community lacks a decent analytical...

Full Text:: fiber/matrix modulus ratios of R = Ef/Em < 30 and relatively short fiber aspect ratios, ρ = lf/df < 30

Creator:: Thomas, Nicholas O.
Abstract:: Over the past century, life expectancy in the United States has dramatically increased leading to an increasingly aging population with people reaching, and spending more years in ‘old age’. While this unprecedented shift in population demographics represents great strides for humanity, it is not without cost. One consequence of longer...

Creator:: Shaw, Subrata
Abstract:: This thesis describes the development of a new enantioselective synthetic method employing chiral cis-2,5-diaminobicyclo[2.2.2]octane-based organometallic catalysts. The significance of this new method to organic synthesis is illustrated with preparation of enantioenriched products that are transformed to important pharmaceutical agents. Chapter 1 provides a brief historical overview of asymmetric catalysis, especially...

Creator:: Hruschka, Michael Archimedes and Hruschka, Michael A.
Abstract:: The use of an adjacency matrix to determine distant (not maximal or minimal) subgroup and supergroup relationships between crystallographic spacegroup types is described. Full lists of space-group types that are supergroups and subgroups for every space-group type were compiled. A list of the space-group types connected to each space-group type...
