  • Functions and regulation of cytokinin glucosyltransferases

    Creator:
    Pineda Rodó, Albert
    Abstract:
    Cytokinins can be conjugated to N- and O-glucosides. While N-glucosylation generally leads to irretrievable loss of activity, O-glucosides are thought to play an important role in cytokinin storage and homeostasis since they can be hydrolyzed to the corresponding aglycones. The first zeatin O-glycosyltransferase genes isolated were ZOG1 and ZOX1 from...

  • A Multi-Tiered Approach Using Daphnia magna to Assess Chlorpyrifos Risk to Aquatic Receptors

    Creator:
    Maggio, Stephanie A.
    Abstract:
    Chlorpyrifos (CPF) is a widely used broad-spectrum organophosphate insecticide. Following exposures, CPF and its more toxic oxon metabolite (CPFO) elicit neurotoxic effects by inhibiting the activity of the acetylcholinesterase enzyme (AChE), resulting in altered fitness and death at high doses. Following exposure, organisms bioactivate CPF to CPFO through the Cytochrome...

  • On the Topologies of Moduli Spaces of Polygons: A Taxonomic Approach

    Creator:
    Krughoff, Stephen A.
    Abstract:
    Consider a polygon lying in the Euclidean plane with labeled edge lengths. The moduli space of polygons is the space of all polygons with the same labeled edge lengths, modulo orientation preserving isometries. It is well known that this space is generically a smooth manifold. For certain combinations of edge...

  • Synthesis and study of transparent p- and n-type semiconductors and luminescent materials

    Creator:
    Park, Cheol-Hee
    Abstract:
    New transparent p- and n-type semiconductors and luminescent materials have been prepared and characterized. Synthesis, structures, optical and electrical properties of new chalcogenide fluoride p-type transparent semiconductors MCuQF (M=Ba, Sr; Q=S, Se, Te) are described. Band-gap tuning and improvement in conductivity through p-type doping are demonstrated in the family. The...

  • A photoactivable microfluidic device for heavy metal ion extraction

    Creator:
    Nammoonnoy, Jintana
    Abstract:
    The development of microfluidic devices for heavy metal extraction is presented in this dissertation. Various research areas, covering subjects from photochromic compound syntheses to microchip fabrication techniques are explored to develop microfluidic devices capable of extracting heavy metal ions from drinking water. Through integration of the beneficial characteristics of both...

  • Economics of drought preparedness and response in irrigated agriculture

    Creator:
    Peck, Dannele E.
    Abstract:
    The impact of recent severe droughts throughout the United States, the potential for climate change to intensify the frequency and severity of drought, and discussion about the future of government assistance in agriculture highlight the need for a transition from drought as ‘disaster’ to drought as ‘managed risk’. However, guidance...

  • Essays on conservation policies and agricultural nonpoint source pollution control

    Creator:
    Tanaka, Katsuya
    Abstract:
    This dissertation consists of three papers on agricultural nonpoint source pollution and control. The first paper focuses primarily on agricultural land use changes under alternative conservation policies. The second and third papers address environmental implications of these policies and their cost effectiveness. In the first paper, the effect of alternative...

  • Breaking of spherical symmetry in electronic structure, free and immersed atoms in an electron gas

    Creator:
    Dorsett, Skye Forrest
    Abstract:
    Total electronic energies are calculated numerically for free and singly-ionized He, Li, C, and Ne atoms using density functional theory. Immersion energies are calculated for a single C impurity atom embedded or absorbed into a charge-neutral system composed of a free-electron gas with uniform positive background, also called 'jellium'. Nonspherical...

  • Nonlinear internal waves on the continental shelf

    Creator:
    Shroyer, Emily L.
    Abstract:
    The properties and evolution of nonlinear internal waves (NLIWs) depend upon the background conditions within which waves form, propagate, and dissipate. As a result, the NLIW field on the New Jersey shelf displayed dramatic variability during the Shallow Water 2006 experiment. Wave variability was exhibited by 1) amplitudes that ranged...

  • Environmental complex mixtures modify benzo[a]pyrene and dibenzo[a,l]pyrene-induced carcinogenesis

    Creator:
    Courter, Lauren A.
    Abstract:
    Human exposure to the carcinogenic polycyclic aromatic hydrocarbons (PAHs) benzo[a]pyrene (B[a]P) and dibenzo[a,l]pyrene (DB[a,l]P) is through environmental complex mixtures, such as urban dust particulate matter (UDPM) and diesel exhaust (DE), however the potency of these PAH within a mixture is not established. To determine the effect of these mixtures on...
