Probing Molecular Free Energy Landscapes By Periodic Loading, Oliver Braun, Andreas Hanke, Udo Seifert Jan 2004

Probing Molecular Free Energy Landscapes By Periodic Loading, Oliver Braun, Andreas Hanke, Udo Seifert

Physics & Astronomy Faculty Publications

Single molecule pulling experiments provide information about interactions in biomolecules that cannot be obtained by any other method. However, the reconstruction of the molecule’s free energy profile from the experimental data is still a challenge, in particular, for the unstable barrier regions. We propose a new method for obtaining the full profile by introducing a periodic ramp and using Jarzynski’s relation for obtaining equilibrium quantities from nonequilibrium data. Our simulated experiments show that this method delivers significant more accurate data than previous methods, under the constraint of equal experimental effort.

Residents' Attitudes And Perceptions Toward National Parks And Ecotourism Development In Ghana: The Case Of Dome Community In The Digya National Park, Paul Owusu Boi Jan 2004

Residents' Attitudes And Perceptions Toward National Parks And Ecotourism Development In Ghana: The Case Of Dome Community In The Digya National Park, Paul Owusu Boi

Theses and Dissertations (Comprehensive)

The mode of park establishment generally conflicts with the use of natural resources as traditionally demanded by resident communities. These conflicts become compounded as a result of the process of land acquisition. Consequently, the process leads to formation of varied attitudes and perceptions that residents have towards national parks. The impacts of this attitude formation spread to any developments in the parks. There are many studies on attitudes of park residents toward tourism development in parks, however, only a few have examined attitudes and perceptions in the pre-development stage of tourism. This research uses a case study approach to examine …

An Evaluative Framework For Assessing Information Management In Watershed Management: The Case Of The Grand River Conservation Authority (Ontario), Robert Scott Brown Jan 2004

An Evaluative Framework For Assessing Information Management In Watershed Management: The Case Of The Grand River Conservation Authority (Ontario), Robert Scott Brown

Theses and Dissertations (Comprehensive)

Watershed management has been rapidly evolving over the last 50 years. The current focus has been adaptive and ecosystem-based approaches to watershed management, redefining roles, responsibilities, and relationships of watershed organizations. While entire management models need to be heavily scrutinized, the practices and policies surrounding information are fundamentally important. Information forms the understanding and knowledge for watershed decision-making. Watershed organizations need to be critical of the policies and practices affecting their collection, storage, processing, analysis, monitoring, and reporting of data and information. Among the Conservation Authorities, the GRCA has developed a proficiency at information management, doing it as well as …

Forest Fires, Woodland Caribou And Land Use Policies In Northwestern Ontario (Rangifer Tarandus), Brian Frederick Kutas Jan 2004

Forest Fires, Woodland Caribou And Land Use Policies In Northwestern Ontario (Rangifer Tarandus), Brian Frederick Kutas

Theses and Dissertations (Comprehensive)

Woodland caribou (Rangifer tarandus caribou) are a threatened species in Ontario's boreal forest. Caribou require habitat that supports appropriate forage, including large areas of lichen rich forests. This research examines two dynamics that influence woodland caribou habitat in northwestern Ontario. These dynamics are forest fires and land use policies. The effects of forest fires are assessed quantitatively at both the ecosite and landscape scales within Woodland Caribou Provincial Park. Land use policy and management activities are evaluated using a case study and a policy analysis of protected area and forest management approaches to woodland caribou conservation in this region. Forest …

Impacts At The Coast: Climate Change Influences On Lake Huron's Water Levels At Oliphant (Ontario), Kevin Tupman Jan 2004

Impacts At The Coast: Climate Change Influences On Lake Huron's Water Levels At Oliphant (Ontario), Kevin Tupman

Theses and Dissertations (Comprehensive)

Since 1998, climate change induced low water levels in the Great Lakes have caused environmental and socioeconomic impacts along most of the Great Lakes' shorelines. According to recent climate change research involving different water level scenarios, climate change over the next century may continue to cause water levels in the Great Lakes to decline. Such impacts may include wider shorelines, drying of coastal wetlands, and navigation hazards that may result in increased dredging activities. These impacts will have a strong influence on new shoreline management policies and planning. To better understand potential future impacts, a specific methodology was developed to …

A Media Literacy Intervention: Using Self-Objectification As A Tool For Identifying Changes In Well-Being And Internalization, Becky L. Choma Jan 2004

A Media Literacy Intervention: Using Self-Objectification As A Tool For Identifying Changes In Well-Being And Internalization, Becky L. Choma

Theses and Dissertations (Comprehensive)

According to objectification theory, females are socialised to internalize a third person perspective of their own physical appearance (Fredrickson & Roberts, 1997), which in turn serves to decrease well-being (Sands & Wardle, 2003). In our culture, one of the biggest culprits for portraying a negative perspective of women's bodies is media (Thompson & Heinberg, 1999). In an effort to combat the harmful effects of media, researchers have suggested that being able to critically evaluate (i.e., media literacy) such messages may be helpful (Tiggeman, Gardiner, & Slater, 2000). Past research has failed to measure trait self-objectification (TSO: high, low) and its …

Spectrum Visualization And Measurement Of Power Parameters Of Microwave Wide-Band Noise, Marina Koledintseva, Alexander A. Kitaytsev, V. A. Konkin, V. Radchenko Jan 2004

Spectrum Visualization And Measurement Of Power Parameters Of Microwave Wide-Band Noise, Marina Koledintseva, Alexander A. Kitaytsev, V. A. Konkin, V. Radchenko

Electrical and Computer Engineering Faculty Research & Creative Works

A method for an adequate visualization of a microwave intense noise spectrum envelope in a wide frequency range (several octaves), measurement of its power parameters, and detection of a narrow-band signal with unknown frequency and power against the noise background is presented. This method is based on an application of a nonheterodyne principle of microwave frequency (and power) conversion using a gyromagnetic converter, which operates in two regimes in turn: the resonance detection and the cross-multiplication. A block scheme and an operation of a two-channel measuring device combining the mentioned functions are discussed.

United States Department of Agriculture Wildlife Services: Staff Publications

Tilapia (Oreochromis mossambicus) have been implicated as the source of type C toxin in avian botulism outbreaks in pelicans (Pelecanus erythrorhynchos, Pelecanus occidentalis californicus) at the Salton Sea in southern California (USA). We collected sick, dead, and healthy fish from various sites throughout the Sea during the summers of 1999 through 2001 and tested them for the presence of Clostridium botulinum type C cells by polymerase chain reaction targeting the C1 neurotoxin gene. Four of 96 (4%), 57 of 664 (9%), and five of 355 (1%) tilapia tested were positive for C. botulinum type C …

Economic Development And Convergence Revisited: The Role Of Agricultural Modernization, Richard Grabowski, Sharmistha Self Jan 2004

Economic Development And Convergence Revisited: The Role Of Agricultural Modernization, Richard Grabowski, Sharmistha Self

Economics Discussion Papers

In earlier debates on economic development, the agricultural sector’s role was somewhat controversial. While dualistic models highlighted the importance of agriculture the mainstream literature placed a greater emphasis on the creation of a modern industrial sector. Soon agriculture disappeared from the mainstream development literature to re-emerge recently with a variety of multiple-sector growth models emphasizing the key role of agriculture. This paper is an empirical cross-country analysis of agriculture’s role in economic development. The focus is the importance of agricultural modernization as a precondition for convergence in postwar growth rates as well as an indicator for overall growth and wellbeing.

Via Coupling Within Power-Return Plane Structures Considering The Radiation Loss, J. Chen, Todd H. Hubing, Weimin Shi, R. L. Chen Jan 2004

Via Coupling Within Power-Return Plane Structures Considering The Radiation Loss, J. Chen, Todd H. Hubing, Weimin Shi, R. L. Chen

Electrical and Computer Engineering Faculty Research & Creative Works

An accurate analytical model to predict via coupling within rectangular power-return plane structures is developed. Loss mechanisms, including radiation loss, dielectric loss, and conductor loss, are considered. The radiation loss is incorporated into a complex propagating wavenumber as an artificial loss mechanism. The quality factors associated with the three loss mechanisms are calculated and compared. The effects of radiation loss on input impedances and reflection coefficients are investigated for both high-dielectric-loss and low-dielectric-loss PCBs. Measurements are performed to validate the effectiveness of the model.

Gandhi And Justice, Raymond B. Marcin Jan 2004

Gandhi And Justice, Raymond B. Marcin

Scholarly Articles

Mohandas K. Gandhi, the great and saintly Mahatma of India, once made a characteristic but nonetheless provocative statement about justice: “That action alone is just,” he wrote, “which does not harm either party to a dispute.” There have been instances in Western jurisprudence in which that Gandhian—essentially Eastern - understanding of justice sometimes surfaces. Several decades ago, Martin Luther King Jr., in a groundswell of Gandhian activism, raised that Gandhian understanding of justice to a position of near dominance in Western thought. It may be no coincidence that both King and Gandhi suffered the same fate for their troubles. Conventional …

Evidentiary Surrogacy And Risk Allocation: Understanding Imputed Knowledge And Notice In Modern Agency Law, Marin Roger Scordato Jan 2004

Evidentiary Surrogacy And Risk Allocation: Understanding Imputed Knowledge And Notice In Modern Agency Law, Marin Roger Scordato

Scholarly Articles

This article deals with the imputed knowledge rule in agency law. The basic rule imputes to a principal knowledge or notice received by an agent within the scope of the agent's authority. The principal is deemed to have received the information in question even in the absence of any evidence that the agent successfully transmitted it to the principal.

As the article clearly demonstrates, the imputed knowledge rule is currently characterized by complexity and contradiction. The analysis developed in the article suggests that this convolution and uncertainty is the result of the existence of a fundamental tension residing at the …

Diagnosis Of Condition Systems, Jeffrey Ashley Jan 2004

Diagnosis Of Condition Systems, Jeffrey Ashley

University of Kentucky Doctoral Dissertations

In this dissertation, we explore the problem of fault detection and fault diagnosis for systems modeled as condition systems. A condition system is a Petri net based framework of components which interact with each other and the external environment through the use of condition signals. First, a system FAULT is defined as an observed behavior which does not correspond to any expected behavior, where the expected behavior is defined through condition system models. A DETECTION is the determination that the system is not behaving as expected according to the model of the system. A DIAGNOSIS of this fault localizes the …
