  • Turbulence in sheared, salt-fingering favorable environment

    Creator:
    Kimura, Satoshi
    Abstract:
    Instability and turbulence in sheared, salt-fingering favorable stratification are studied using three-dimensional direct numerical simulations (DNS). Salt-fingering favorable stratification is gravitationally stable, because the unstable vertical gradient of salinity is stabilized by temperature (warm, salty over cool, fresh water-masses). Salt-fingering instability can occur at the interface of these different water-masses....

  • Turbulence and biophysical fluxes in the near surface ocean

    Creator:
    Hoecker-Martínez, Martín
    Abstract:
    Vertical transports of plankton, momentum, heat, and turbulence are modeled. A novel integration of high resolution turbulence and biophysical modeling is used to show the influence of a Kelvin-Helmholtz instability on the vertical migration of simple gyrotactic organisms. A viscous limit on mixing driven by shear turbulence is proposed. Large...

  • Characterization of the transition to the progamic phase in Zea mays pollen

    Creator:
    Smyth, Johanna C.
    Abstract:
    The transition of mature pollen to the progamic phase represents an important step in the regulation of plant sexual reproduction. The progamic phase encompasses the initiation of pollen tube germination, growth of the pollen tube through the stigma (the silk in maize) and concludes with fertilization of the female gametophyte....

  • A modeling study on downslope windstorms

    Creator:
    Smith, Craig M.
    Abstract:
    The generation mechanism for downslope windstorms was shown to vary according to inversion height and strength using a series of numerical experiments. Strong low level inversions were dominated by interfacial waves on the inversion, while high level inversion and cases without an inversion were dominated by internal gravity wave (IGW)...

  • Modeling shallow-water hydrodynamics : rotations, rips, and rivers

    Creator:
    Long, Joseph W.
    Abstract:
    Hydrodynamic models are used as a diagnostic tool to understand the temporal variability of shallow-water processes that are difficult to completely resolve with traditional field measurements. For all simulations, modeled quantities are qualitatively or quantitatively compared with available measurements to gain confidence in conclusions derived from the modeled results. In...

  • Data assimilation for prediction of shallow water flows with uncertain bathymetry

    Creator:
    Wilson, Gregory W.
    Abstract:
    A new method is introduced for incorporating bathymetric uncertainty into predictions of nearshore and river flows (i.e., unstratified flows primarily forced by pressure and radiation stress gradients). The method involves the use of the ensemble Kalman filter (EnKF) as a parameter estimation scheme, where the parameter to be estimated is...

  • Transcriptional regulation of the human cathelicidin antimicrobial peptide gene

    Creator:
    Guo, Chunxiao
    Abstract:
    Human cathelicidin antimicrobial peptide (CAMP/LL-37) is a cationic antimicrobial peptide that is widely expressed by myeloid and epithelial cells at the human-environment interface. It possesses broad spectrum antimicrobial capacity against bacteria, fungi and viruses. In addition to its direct antimicrobial activity, CAMP/LL-37 also attracts and recruits monocytes, neutrophils and other...

  • The influence of selenium on selenoprotein W

    Creator:
    Yeh, Jan-ying
    Abstract:
    The objective of our study was to investigate the effect of selenium on selenoprotein W. Western blot analysis indicated that selenoprotein W is present in muscle, brain, testis and spleen of rat tissues. Tissue distribution of selenoprotein W was not altered in rats fed various selenium levels. Among muscle, brain,...

  • Characterization of rodent selenoprotein W promoter

    Creator:
    Amantana, Adams
    Abstract:
    Rat selenoprotein W (SeW) promoter activity was investigated using different concentrations of cadmium, copper, and zinc. Two fragments (404bp and 1265bp) of the SeW promoter, containing a single metal response element (MRE), were ligated into the multiple cloning site of a pGL3-Basic reporter plasmid. The constructs were transfected into cultured...
