Employing a two-stage least-squares multiple regression technique using cross-sectional data from metropolitan statistical areas (MSAs) as the unit of analysis, this study is designed to detect the indirect effect of skill-biased technological...
Medical policy--Kentucky--Louisville; Political planning--Kentucky--Louisville; Cities and towns--Growth--Kentucky--Louisville
A disciplined-configurative case study design was carried out to explore whether a growth machine exists and shapes local healthcare policy in Louisville. A historical analysis first explored whether a growth machine existed in Louisville in the...
Aluminum fiber metal laminates (AFMLs) are a promising new type of fiber metal laminate that consists of aluminum foils interleaved with layers of a graphite fiber-polymer matrix composite (PMC) material. AFMLs combine the attractive features of...
III-nitrides (InN, GaN, AlN) are some of the most promising materials for making blue light emitting diodes (LED), blue laser diodes (LD) and high power, high temperature field effect transistors (FET). Current techniques produce GaN films with...
Ten algal isolates were obtained from soil into axenic culture and placed into defined media containing from 0 to 50 ppm of DDT, 2, 4-D,2,4,5-T, rotenone, or malathion (in two purities, 95 and 99%). For nine of the isolates, growth was measured...
Rising environmental concerns due to our rising population ad energy demand along with our excessive dependence on fossil fuels has created an urgent need to find clean, renewable and carbon free source of energy. Photoelectrochemical (PEC) water...
More than 50% of the total energy produced is typically rejected in the form of waste heat from various processes. The grand challenge is that most of this waste heat is released at temperatures much lower than 1000 C, which makes it difficult to...
Understanding the nucleation and early stage growth of crystals from the vapor phase is important for realizing large-area single-crystal quality films, controlled synthesis of nanocrystals, and the possible discovery of new phases of materials....
Soon after the atomic theory was established, it was found that the plant uses as sources of food not only the air and water, but also different constituents of the soil, dissolved in the soil moisture—the mineral nutrients. Ashes of different...
This dissertation explores the physical and biological factors that control zooplankton population growth rates in the Ohio River (USA). I employed both observational studies and a mesocosm experiment to ascertain zooplankton population and...
Freshwater zooplankton; Global warming; Nitrogen--Environmental aspects
Aquatic ecosystems face major transformations as humans increasingly alter their environment by introducing exotic species and changing the temperature regime and nutrient availability of freshwater systems. The impacts of such alterations of...
Crystalline beta-Ga2O3 nanowires with two distinct morphologies have been synthesized through simple physical evaporation of Te doped GaAs powder in argon atmosphere. The structure of the nanowires was characterized by SEM, TEM, XRD, EDX, and raman...
Dimorphism is a highly conserved process in fungi in which a transition between a unicellular, yeast-like growth form and either a unicellular or multicellular, filamentous growth form occurs in response to several different environmental cues. The...
Many species of fungi undergo a dimorphic transition to switch from a unicellular yeast-like growth form to a filamentous growth form. Ustilago maydis undergoes such a transition, in response to successful mating events and subsequent host cues, to...
Monoclonal antibodies directed toward tumor associated antigens are FDA approved anticancer reagents used commonly in the clinic. Administered antibodies initiate tumor cell death through several mechanisms. Improving immune mediated mechanisms,...
This dissertation describes galvanic exchange of silver (Ag) nanostructures with PdCl42- in 1) various PdCl42- concentrations, 2) the presence of 0.1 M cetyitrimethylammonium bromide (CTAB), and 3) the presence of 0.1 M potassium bromide (KBr). It...
Pituitary tumor transforming gene ( PTTG ), also known as securing, is a novel oncogene that is expressed at high levels in most of the tumors analyzed to date. Overexpression of PTTG in mouse fibroblast(NIH 3T3) cells increases cell proliferation,...
Periodontitis; Iron--Health aspects; Iron in the body
The dental pathogen A. actinomycetemcomitans, a Gram- negative organism, has been associated with aggressive forms of periodontitis. A. actinomycetemcomitans requires iron to grow. In the host, iron-binding proteins such as transferrin,...
Naja kaouthia is a significant species because it feeds primarily on agricultural pests, causes human mortality, and is commercially exploited. Understanding the life history and demography of harvested populations is essential to providing...
This study explores four economic development theories – classical location theory, human capital theory, agglomeration economies theory and creative cities theory, and their effectiveness in explaining the spatial distribution of high tech...
