Enhance Dopamine Autoreceptor Functioning During Blockade Of Dopamine Transporters, Rachel Laura Pace

Electronic Theses and Dissertations Archive

Dopamine autoreceptors (DARs) and dopamine transporters (DATs) influence dopamine transmission in the brain's mesolimbic pathway. Prior studies have focused on how activation of DARs influences trafficking of DATs, but how DATs influence DARs remains unclear. Male and female C57BL/6J mice received daily injections of either cocaine (DAT blocker) or saline for seven days then underwent stereotaxic surgery to obtain fixed potential amperometric recordings of DAR-mediated dopamine release. All mice received a mid-surgery injection of cocaine, and DAR-mediated dopamine release was assessed once more during maximal DAT blockade. The current study found that DAR functionality was increased during peak cocaine effects, …

Can We Sustain Sustainability? A Critical Synthesis Of Pertinent Literature, Jay L. Brand, Sally J. Augustin

Faculty Publications

Architects and designers, along with their corporate clients, generally embrace the importance of environmental stewardship, saving the earth’s ecosystem, and sustainable design. However, research is needed to link sustainable design with relevant human behavior (e.g., in corporate offices and educational settings) to ensure its enduring legacy. Regarding changing people’s behavior, the majority of human experience results from unconscious processes, i.e., brain–environment interactions not available to awareness; thus, in general, people cannot articulate the nature of these associations. Using theoretical roots stemming from William James and running through ecological psychology (e.g., James J. Gibson to Roger Barker), Harry Heft has argued …

Ecological Genomics Of Two Coastal Foundation Plant Species, Jeannie Mounger

USF Tampa Graduate Theses and Dissertations

I was born and raised in rural Florida on a tributary of the Withlacoochee River. “Withlacoochee” comes from a series of Muscogee Creek words that together mean “big little water,” possibly owing to the seasonal fluctuations in the breadth and flow of the river or to the chain of lakes that in part form it. The name contains within it an understanding of the capacity of land and water to undergo great shifts. It conjures images of mutable boundaries, of water covering and receding across the landscape over and over again. Many of my clearest memories from childhood are related …

Letitia Carson In Court: African American Women, Property, And Wages In The Pacific Northwest, Stephanie Marie Vallance

Dissertations and Theses

Letitia Carson arrived in Oregon from Missouri in 1845, accompanied by David Carson and their newborn child, a daughter named Martha. The Carsons settled in the Soap Creek Valley and took advantage of Oregon's Provisional Government's donation land claim program, living on 640 acres in the newly formed Benton County with Martha and a second child, a son named Adam, born a few years after arriving in Oregon. Within ten years, however, David would be dead and Letitia would be dispossessed of all property and belongings. A former slave, Letitia had little social standing in the new territory and no …

The Photophysical Studies Of Transition Metal Polyimines Encapsulated In Metal Organic Frameworks (Mof’S), Jacob M. Mayers

USF Tampa Graduate Theses and Dissertations

Light harvesting systems provide a platform that converts solar energy into other forms of energy. One of the most common examples of photon capturing and conversion into chemical energy is observed in photosynthetic organisms in both Eurkaroyic and Prokaryotic domains. Nature provides a model for successful light harvesting platforms which includes the compartmentalization of antenna complexes that contain separated donor and acceptor pairs that participate in efficient electron transfer processes. In order to mimic such systems, crystalline porous materials that exhibits regular cavities and pore dimensions provides an excellent starting place. Metal organic frameworks (MOFs) are a class of porous …

Research On Forage Quality: Progress And Priorities, J. A. Milne

IGC Proceedings (1977-2023)

A broad definition of forage quality is used and the purposes for which research on forage quality is undertaken currently are outlined. These range from research that provides simple measurements that describes the forage quality of a commercial product to research on forage quality to improve understanding of digestion processes. Much of the research in the last decade has related to improving predictive measurements. The different degrees of progress that have been made in the development and use of measurements to further our understanding of forage quality are described and related to their fitness of purpose.

Forage Quality And The Environment, C. E. Lascano, A. Schmidt, R. Barahona

IGC Proceedings (1977-2023)

The influence of environmental factors on forage quality of temperate and tropical grasses has been reviewed by several authors, who summarized how light, temperature, drought and soil nutrients influence chemical composition, and digestibility of forages grown in contrasting areas of the world. The effects of season of the year on forage growth, grazing behavior and animal performance have also been the subject of numerous papers and reviews. However, there are few recent reviews that summarize how changes in climatic and edaphic factors influence forage quality of legumes with variable levels of condensed tannins (CT), which are important secondary compounds in …

The Effect Of Perennial Ryegrass Cultivar Lock Up Length And Nitrogen On Forage Quality For Silage, Joseph L. Jacobs, Frank R. Mckenzie, G. N. Ward

IGC Proceedings (1977-2023)

A study was undertaken to determine the effects of three perennial ryegrass (Lolium perenne L.) cultivars (Vedette, Impact and Nevis) with differing maturities, lock up length and nitrogen (N) application upon the dry matter (DM) yield and nutritive characteristics of pasture for silage. The addition of N at 50 kgN/ha significantly (P< 0.05) increased DM yield for all cultivars. Metabolisable energy (ME) (MJ/kgDM) of the ryegrass declined with time for all treatments, although by week 8 of lock up the ME content of Vedette was significantly (P< 0.05) lower than for other cultivars. When the DM yield and ME content of ryegrass at early ear emergence for each cultivar was compared, the harvestable metabolisable energy (MJ/ha) was highest for Nevis followed by Impact and Vedette. In conclusion, there is potential to use later maturing cultivars of ryegrass in south east Australia to allow for later harvesting of forage for silage, whilst maintaining ME and maximising DM yields. Furthermore the use of N fertiliser can also increase DM yields without impinging on pasture quality.

Screening Fresh Forages For Protein Degradation And Nutritive Value, Garry C. Waghorn, J. L. Burke

Are Good Deeds Being Punished?: Independent Charity Patient Assistance Programs And The Anti-Kickback Statute, John C. Hood

Florida Law Review

Largely funded by the pharmaceutical industry, Independent Charity Patient Assistance Programs (PAPs) dispense billions of dollars of aid annually to help financially vulnerable patients afford their prescription drugs. Recently, these charitable entities and their drug company donors have faced mounting legal scrutiny for allegedly funneling illegal kickbacks to Medicare beneficiaries. This Note examines Independent Charity PAPs and the issues they raise under the Anti-Kickback Statute (AKS). It explores the uncertain legal environment in which Independent Charity PAPs operate and concludes that a new AKS regulatory safe harbor may be necessary to preserve the viability of the safety net assistance that …

Brood Abundance And Invertebrate Availability In Crop-Dominated Landscapes In The Prairie Pothole Region, Catrina V. Terry

LSU Master's Theses

The Prairie Pothole Region (PPR) is the most important region for ducks in North America, producing over half the ducks on the continent, and it is a priority landscape for wetland and grassland conservation. Agricultural expansion has changed the PPR, and the majority of grasslands and potholes have been converted into row-crops. The loss of nesting habitat has directly caused nest success to decline. Most of the remaining wetlands are surrounded by row-crops, and are considered lower quality because they receive runoff of sediment and chemicals, which may decrease primary forage for young ducklings as well as inhibit wetland vegetation. …

Representations Of Music: Neural Foundations And Metaphoric Descriptions, Wilfried Gruhn

Visions of Research in Music Education

In Jeanne Bamberger's (1991) instructive case study on Jeff's learning, Bamberger observed and systematically ordered altering states of mental representations. In this study, Bamberger introduced and discussed a differentiated perspective on various forms of representation. In addressing the processing of music in the mind, mental representations can refer specifically to neural correlates of music or they can address more metaphoric ideas. Therefore, there is a proposed differentiation between mental representations if the mind is involved and neural representations if the brain is addressed. Furthermore, corporeal sensations and bodily excitations provide a necessary prerequisite for the development of mental and neural …
