High Resolution Circulation of the Hawkesbury Shelf Region, SE Australia: Mean, Variability and Transport Pathways
… on the shelf. Mean along and across-shelf transports are quantified to identify major regions of ocean/shelf exchange and its spatial and temporal variability. Throughout the year, maximum shelf-water export is associated with the eastward separation of the EAC jet between 31 and 32.5oS. …

An investigation of metal contaminants in sediments of Arctic Svalbard: Inferences for sources and transport pathways
… sites allowed the identification of the major transport pathways within this region and the relative importance of atmospheric and oceanic transport. Three cores were taken from the inner Kongsfjorden area, four cores from the Barents Sea, with three further cores taken from the Vøring Plateau …

Modifications in the transport pathways of graphene oxide-based membrane with varying flake size and thickness
Mass transport pathways are widely recognized as a vital role for studying graphene oxide membrane (GOM)-based water purification and dye rejection applications. Based on the structural features, GO flake size and membrane thickness, it is observed that the thicker GOMs composed of larger flake …

The Role of Hydrocortisone on the Development and Maintenance of Ion Transport Pathways Essential to Mucociliary Clearance in Differentiated Normal Human Bronchial Epithelial Cells
… protein kinase A (PKA) dependent signaling pathways in airway smooth muscle, leading to relaxation and a decrease in airway resistance. The therapeutic benefit of ICS treatment is attributed to transrepression of specific genes induced by proinflammatory transcription factors such as NF-kB …

From Field to Home: Assessing Air Infiltration and Soil Track-in Transport Pathways of Agricultural Pesticides into Farmworkers' Home and Identifying Risk Factors for Increased In-Home Pesticide Levels
… the take-home/soil track-in and air infiltration pathways of agricultural pesticides into homes, as well as identifies the risk factors for increased in-home agricultural pesticide levels for farmworkers and their families living near agriculture fields. Samples of outdoor air, yard soil, and …

Concentration and distribution of organic phosphorus through a grassland catchment transfer continuum
… continuum from soils to surface and sub-surface transport pathways and ultimately into the stream water channel, within the River Eden catchment in Cumbria, England. The aims of the study were to: (i) quantify the magnitude of different P compounds, including DNA-P and PLD-P, in grassland …

The intraorgan lymphatic system of the rat left ventricle in normalcy and aging
… in the accepted visible macromolecular transport pathways. Lymphatic vessels were found in both epicardial and myocardial areas. No endocardial lymphatics were found. Both intercellular and transendothelial visible macromolecular transport pathways were examined in 3, 6, 12, 18, and 28 …

Electrical conduction in metal-organic frameworks
… MOFs to date with the focus on potential charge transport pathways and the origin of charge carriers. Chapter 2 uses Cd₂(TTFTB) as a case study to discuss methods and techniques for measuring electrical conductivity in pressed pellets and single crystals, establishing a standard protocol for …

From Representative Period Selection to Process‐Based Sediment Dynamics
… tides, waves and wind jointly govern sediment transport. Despite its ecological and morphological significance, the region remains comparatively understudied, and its typical residual and storm-driven sediment pathways are poorly understood. This thesis develops an integrated, process-based …

The role of copper in Parkinson's disease
… copper levels and potential changes in copper transport in the Parkinson s disease brain to determine if altered copper levels associate with altered copper transport and affect the function of the antioxidant cuproprotein, superoxide dismutase 1 (SOD1). Characterisation of regional copper …

Optical Signatures of Bioavailable and Terrigenous Dissolved Organic Matter Across Long Island Sound and Hudson River Estuaries
… framework for examining the sources, sinks, and transport pathways of dissolved organic matter (DOM) across the land–ocean aquatic continuum. By integrating observations across spatial and temporal scales, optical properties are shown to encode fundamental processes governing DOM cycling in …

STRUCTURE AND FUNCTION OF A NEURONAL GLUTAMATE TRANSPORTER
<p>Glutamate transporters have a homotrimeric subunit structure with a large central water-filled cavity that extends partially into the plane of the lipid bilayer (Yernool et al., 2004). In addition to uptake of glutamate, the transporters also mediate a chloride conductance that is gated by Na+ …

Regional Variation in Migratory Behavior and Reproductive Output of The Gulf Of Mexico Blue Crab Spawning Stock
… location is a primary determinant of larval transport pathways, understanding spawning locations and offshore movements of female blue crabs can inform stock identification and potentially clarify the somewhat conflicting population genetic information available for blue crabs. A large-scale …

Development of Environmental Tracers for Sediments and Phosphorus.
… soil erosion by improving the understanding of transport processes. A large range of sediment tracers exists; however, to date there has been no combined use of tracers which represent the full particle size range of sediments transported in overland flow. This is relevant because particles of …

Hypsometric and geometric controls on hydrodynamics, tidal asymmetry, and sediment connectivity in shallow estuarine systems
… tides, meteorological forcing, and sediment transport processes. This thesis focuses on the fundamental links between these physical processes, and the geomorphologic characteristics of shallow estuarine systems, specifically: (i) how shallow basin geometries and hypsometries affect …

Investigations into the effects of berry flavonoids on nutrient transport processes in Caco-2 enterocytes
… are known to interact with a number of membrane transporters, influencing the rate of intestinal nutrient absorption. The transcriptional effects and consequences of such interactions remained to be fully elucidated. To address this we carried out gene expression microarray analysis on intestinal …
