Major Elements Geochemistry Of The Breiner Baiut Ore Deposit (Gutai Mountains, Eastern Carpathians), Dan Costin

Studia UBB Geologia

The Breiner Băiuţ epithermal vein – type deposit is basically a base metal ore body with important amounts of gold and silver. The frequency distribution pattern of the major elements (Au, Ag, Pb, Zn, Cu, S) is complex in many cases, but at some mining levels it is lognormal. The correlation coefficient "r" has been calculated for six pairs of major elements. The values are positive and indicate strong correlations between these elements. The average grades values for each major element at all levels have been used to highlight the vertical variation of chemistry of the mineralization. The ore body …

Geologic And Isotopic Models For The Carpathian Crystalline Evolution, Ioan Coriolan Balintoni

Studia UBB Geologia

The majority of Carpathian metamorphics protoliths have TDM model Sm/Nd ages between 1.6 and 2.0 Ga. This suggests an important episode of continental crust formation after the 2.0 Ga. The Biharia lithogroup (Apuseni Mountains) and the Tulghes lithogroup (East Carpathians) furnished Zircon U/Pb ages from metagranitoids and acid metavolcanics, respective, around 500 Ma; this is a sign of existence of some Lower Proterozoic protoliths among Carpathian metamorphics. The bimodal intrusions which are piercing the volcano-sedimentary sequence of Paiuseni lithogroup in Highiş Massif (Apuseni Mountains) have given Permian ages on Zircon U/Pb data. The Paiuseni lithogroup probably represents the fill of …

The Practical Effects Of Delegation: Agencies And The Zoning Of Public Lands And Seas, Josh Eagle

Pepperdine Law Review

Legislative efforts to delegate zoning power to public land and ocean management agencies have generally proven unsuccessful. When given the power to create uniform-use areas such as parks and wilderness areas within their broader jurisdictions, agencies either have opted not to exercise it or have been extremely hesitant to do so. The tepid administrative response to zoning is not surprising. Zoning decisions are politically charged, are likely to offend powerful, concentrated interest groups, and erode the discretion that is the core of agency power. These aspects of zoning decisions explain why, by contrast, all states require that municipal zoning ordinances …

Modulation Of Peripheral Taste Function By Glial-Like Taste Cells, Michael S. Sinclair

Open Access Dissertations

Taste is detected by cells of taste buds in the oral cavity. Mammalian taste buds contain three types of cells: receptor, presynaptic, and glial-like. Of these three, glial-like cells are the least studied. Their only known function is that they clear neurotransmitters from the extracellular space. The present work describes two previously undocumented properties of glial-like cells. First, Oxytocin receptor (OXTR) mRNA was detected by RT-PCR in taste tissue of mice. In the taste buds of Oxtr-YFP knockin mice, YFP was seen in glial-like taste cells and other cells immediately outside the taste bud, but no other cells in oral …

Net Primary Production Data: Konza-Kruger Fire-Grazing Project 2010-2011, Alan Knapp, Melinda Smith, John Blair, Scott Collins, Deron Burkepile, Kevin Kirkman

Sevilleta LTER Program Data

The distribution, structure and function of mesic savanna grasslands are strongly driven by fire regimes, grazing by large herbivores, and their interactions. This research addresses a general question about our understanding of savanna grasslands globally: Is our knowledge of fire and grazing sufficiently general to enable us to make accurate predictions of how these ecosystems will respond to changes in these drivers over time? Some evidence suggests that fire and grazing influence savanna grassland structure and function differently in South Africa (SA) compared to North America (NA). These differences have been attributed to the contingent factors of greater biome age, …

Optical And Mass Spectrometric Studies Of A Helium Dielectric-Barrier Atmospheric-Pressure Plasma Jet Used As An Ambient Desorption Ionization Source, Matthew Spencer Heywood

Theses and Dissertations

Recently there has been a surge in the field of mass spectrometry centered around the concept of rapid analysis of target analytes with minimal or no sample preparation. The target analyte undergoes desorption from its surface of origin and is subsequently ionized under ambient conditions. The technique is termed ambient desorption/ionization mass spectrometry (ADI-MS). Since the introduction of ADI-MS in 2004, there has been an explosion of research based around the development of novel ambient desorption/ionization (ADI) sources with the capability of desorbing and ionizing a variety of target analytes from various sampling surfaces. One type of ADI source uses …

Tracing The Transport Of Colored Dissolved Organic Matter In Water Masses Of The Southern Beaufort Sea: Relationship With Hydrographic Characteristics, A. Matsuoka, A. Bricaud, Ronald Benner, J. Para, R. Sempéré, L. Prieur, S. Bélanger, M. Babin

Faculty Publications

Light absorption by colored dissolved organic matter (CDOM) [aCDOM(λ)] plays an important role in the heat budget of the Arctic Ocean, contributing to the recent decline in sea ice, as well as in biogeochemical processes. We investigated aCDOM(λ) in the Southern Beaufort Sea where a significant amount of CDOM is delivered by the Mackenzie River. In the surface layer, aCDOM(440) showed a strong and negative correlation with salinity, indicating strong river influence and conservative transport in the river plume. Below the mixed layer, a weak but positive correlation between aCDOM(440) and salinity was observed above the upper halocline, resulting from …

Correlates Of Sexually Transmitted Infection Prevention Knowledge Among African American Girls, Dexter R. Voisin

Faculty Scholarship

Purpose: To identify significant factors that distinguish African American girls who have high sexually transmitted infection (STI) prevention knowledge from those lacking such knowledge. Methods: We recruited a sample of 715 African American girls from three public health clinics in downtown Atlanta. Using audio computer-assisted self-interviewing (A-CASI) technology, we assessed for age, self-mastery, employment status, attendance at sex education classes, socioeconomic status, and STI prevention knowledge. Results: Slightly more than one-third of the girls did not know that females are more susceptible to STI infections than males; and that having an STI increases the risk of contracting HIV. Almost half …

Metal Oxide Graphene Nanocomposites For Organic And Heavy Metal Remediation, Tanvir E. Alam

USF Tampa Graduate Theses and Dissertations

This thesis consists of two research problems in the water decontamination area. In the first work, the main focus is to understand the structure and photocatalytic activity of titanium dioxide with graphene (G-TiO2) which is synthesized by using sol-gel method. The photocatalytic activity of TiO2 is limited by the short electron hole pair recombination time. Graphene, with high specific surface area and unique electronic properties, can be used as a good support for TiO2 to enhance the photocatalytic activity. The obtained G-TiO2 photocatalysts has been characterized by X-Ray Diffraction (XRD), Raman Spectroscopy, Transmission Electron Microscopy (TEM), FTIR Spectroscopy and Ultraviolet …

Low-Photoluminescence Hollow Waveguide Platforms For High-Sensitivity Integrated Optical Sensors, Yue Zhao

Theses and Dissertations

This dissertation presents research on the fabrication of optofluidic sensor platforms, which consist of integrated hollow waveguides and solid waveguides. Antiresonant reflecting optical waveguides (ARROWs) filled with liquids or gases, can be used for high-sensitivity sensing in applications of biotechnology, chemical synthesis, and analytical chemistry. The fabrication method developed for integrated ARROW sensing platforms utilizes standard microfabrication processes and materials. Dielectric cladding layers are deposited on a silicon wafer using plasma-enhanced chemical vapor deposition (PECVD) or sputtering. A sacrificial material is then patterned over the bottom cladding layers by photolithography. Additional dielectric layers are deposited around the core, forming the …

Multiscale Feature Analysis Of Salivary Gland Branching Morphogenesis, Melinda Larsen, William P. Daley, Shayoni Ray, Cemal Cagatay Bilgin, Banu Baydil, Bulent Yener

Biological Sciences Faculty Scholarship

Pattern formation in developing tissues involves dynamic spatio-temporal changes in cellular organization and subsequent evolution of functional adult structures. Branching morphogenesis is a developmental mechanism by which patterns are generated in many developing organs, which is controlled by underlying molecular pathways. Understanding the relationship between molecular signaling, cellular behavior and resulting morphological change requires quantification and categorization of the cellular behavior. In this study, tissue-level and cellular changes in developing salivary gland in response to disruption of ROCK-mediated signaling by are modeled by building cell-graphs to compute mathematical features capturing structural properties at multiple scales. These features were used to …
