Analyzing the present and future Pacific-North American teleconnection using global and regional climate models

Creator:: Allan, Andrea M.
Abstract:: In this thesis I present the results of a comprehensive assessment of the Pacific-North American (PNA) teleconnection pattern in general circulation models (GCMs) and a regional climate model (RCM). The PNA teleconnection pattern is a quasi-stationary wave field over the North Pacific and North America that has long been recognized...

The development of a high spectral-resolution laser-excited molecular fluorescence system and its application to gas chromatography and the determination of polynuclear aromatic hydrocarbons

Creator:: Hein, Scott J.
Abstract:: A high-spectral resolution laser-excited molecular fluorescence system was developed that utilizes a pulsed supersonic expansion to simplify the fluorescence excitation spectra of large, gas-phase aromatic molecules diluted in an excess of a monatomic gas. A microcomputer was used to control and synchronize the instrumental components, which included a Chromatix CMX-4...

Selective detection for gas chromatography by ultraviolet spectrometry

Creator:: Van Engelen, Debra L.
Abstract:: Spectrometric detection systems for gas chromatography (GC) based on gas phase ultraviolet absorbance and fluorescence measurements have been developed and evaluated in this research. Polynuclear aromatic compounds (PNAs) are selectively detected by these systems. Limits of detection for PNAs range from 4 ng to 90 ng for absorbance determinations, and...

Microstructure of radiation damage in the uranium film and its backing materials irradiated with 136 MeV 136Xe+26, Microstructure of radiation damage in the uranium film and its backing materials irradiated with 136 MeV ¹³⁶Xe⁺²⁶

Creator:: Sadi, Supriyadi
Abstract:: Microstructure changes in uranium and uranium/metal alloys due to radiation damage are of great interest in nuclear science and engineering. Titanium has attracted attention because of its similarity to Zr. It has been proposed for use in the second generation of fusion reactors due to its resistance to radiation-induced swelling....

The Effects of Host and Pathogen Variation on Infection Dynamics in the Amphibian-Chytrid System

Creator:: Dang, Trang D.
Abstract:: This dissertation uses manipulative experiments to explore amphibian-Bd infection dynamics. Although there has been almost two decades research since the discovery of Bd, many questions still remain regarding what conditions mediate chytridiomycosis virulence. My research shows how certain host and pathogen factors can influence disease virulence. Identifying how host and...

Role of GacSA Two-component System and Bacterial Surface Attachment in Pseudomonas syringae Virulence

Creator:: O'Malley, Megan R.
Abstract:: Pseudomonas syringae are plant pathogenic bacteria that cause disease by rapidly multiplying within the aboveground tissues of host plants. Growth of P. syringae within plant host tissues requires the disarmament of host immune defenses that limit microbial growth. To combat host defenses, P. syringae deploys a type III secretion system...

Ecosystem Photosynthesis and Forest-Atmosphere Interactions Inferred from Carbonyl Sulfide

Creator:: Rastogi, Bharat
Abstract:: An increase in anthropogenic activities since the industrial revolution, primarily due to burning of fossil fuels and changes in land cover, has resulted in a steady increase in the global mean atmospheric CO2 concentrations. While there is unequivocal scientific evidence on global warming and its multidimensional impacts on natural and...

Cellular Recognition, Division, and Proliferation in the Cnidarian-Dinoflagellate Symbiosis

Creator:: Tivey, Trevor R.
Abstract:: Cnidarians and their symbiotic dinoflagellates form a productive mutualism that shapes marine environments. In this symbiosis, dinoflagellate species from the family Symbiodiniacea reside within cnidarian host gastrodermal cells and provide the host with photosynthetically fixed carbon in exchange for host metabolites. This nutritional exchange allows both partners to thrive in...

Investigation of the Patterns and Transcriptional Regulators from Gene Expression Profiles of Adult Murine Soleus and Tibialis Anterior Skeletal Muscles

Creator:: Alto, Sarah I.
Abstract:: Skeletal muscles provide several functions, including, yet not limited to, voluntary body movement and locomotion, posture and body position, and soft tissue support. Skeletal muscles also play a role in metabolism, requiring energy to facilitate contraction. Each skeletal muscle serves a different purpose despite seeming to perform the same task....

The proteomic and transcriptomic responses to iron, sulfur, and nitrogen limitation in the abundant marine bacterium Candidatus Pelagibacter ubique

Creator:: Smith, Daniel P.
Abstract:: Batch cultures of Candidatus Pelagibacter ubique were grown under iron-, organosulfur-, and nitrogen-limiting conditions to understand how this ubiquitous marine bacterium responds to and interacts with environments where growth is limited by the availability of these nutrients. Global gene expression was monitored using microarrays and quantitative mass spectrometry to observe...
