  • A numerical study of coastal stratus cloud in a two-dimensional meso-scale model

    Creator:
    Lee, Tae Young
    Abstract:
    A two-dimensional numerical mesoscale model, which ic1udes radiative and turbulent transfers, has been constructed to study the formation, development and dissipation of coastal stratus cloud under an inversion. In the model, the delta-Eddington and emissivity approximations are used for the solar and thermal radiative transfers, respectively. K-theory parameterization is adopted...

  • Total synthesis of phorboxazole A

    Creator:
    Lee, Tae Hee
    Abstract:
    The total synthesis of a highly potent cytotoxic marine natural product, phorboxazole A, is described. Both a palladium(II)-mediated and a palladium(II)-catalyzed intramolecular alkoxycarbonylation were used as key steps for the preparation of the two cis-2,6-disubstituted tetrahydropyran rings (C22-C26 and C11-C15) of phorboxazole A. The synthesis used a convergent approach involving...

  • How to innovate Korean election by emerging technology

    Creator:
    Lee, Philiph
    Abstract:
    The core element of democracy is elections. Modern elections not only cost a lot of money to conduct elections, but we also bear a lot of social costs when the election is questioned. For this reason, the US and European countries have been considering ways to innovate by introducing IT...

  • Fibrinogen adsorption at heparinized silica interfaces : history dependence and adsorption time effects

    Creator:
    Lee, Hyo Jin
    Abstract:
    Heparin was modified with adipic diliydrazide and covalently linked to surface-activated silica. Contact angle measurements were made to determine changes in surface at various stages of the derivatization. Xray photoelectron spectroscopy was used to analyze the elemental composition of the surface at each step of immobilizing heparin as well and...

  • Molecular origins of surfactant-mediated stabilization of protein

    Creator:
    Lee, Hyo Jin
    Abstract:
    Nonionic surfactants are commonly used to stabilize proteins during upstream and downstream processing and drug formulation. Surfactants stabilize the proteins through two major mechanisms: (i) their preferential location at nearby interfaces, in this way precluding protein adsorption; and/or (ii) their association with protein into "complexes" that prevent proteins from interacting...

  • The Effect of Surface Finish on Ball Grid Array Lead Free Solder Joints

    Creator:
    Casali, Dick R.
    Abstract:
    As microelectronic parts trend smaller so do their solder joints. The surface finish on a copper pad is expected to become a significant part of the total solder joint volume and therefore affect mechanical properties of the smaller solder joints. Two sample geometries and four different surface finishes for tin-silver-copper...

  • Ultrafiltration Membrane Fouling in Side-stream Aerobic Granular Sludge Membrane Bioreactor

    Creator:
    Yang, Zhengjian
    Abstract:
    The integration of low-pressure membrane filtration and aerobic granular sludge (AGS) reactor leads to a novel environmental biotechnological process with strong potential to overcome membrane fouling and demonstrate excellent wastewater treatment performance. However, membrane fouling mechanisms in the AGS based membrane bioreactor (MBR) are lack of systematic elaboration. In the...

  • The conserved biology of herpesvirus latency : a study in cyprinid herpesvirus 3

    Creator:
    Reed, Aimee N.
    Abstract:
    Cyprinid herpesvirus 3 (CyHV-3), commonly known as koi herpesvirus (KHV), is a member of the Alloherpesviridae and is a deadly pathogen for koi and common carp, Cyprinus carpio. It causes severe gill necrosis and nephritis, dermal ulceration and hemorrhage, and mass mortality of up to 100% of affected fish. Fish...
