Force-Velocity Curves Of Motor Proteins Cooperating In Vivo, David A. Dewitt, T. Cahyuti, B. Townsend, J.C. Macosko, Y. Shtridelman Jan 2008

Force-Velocity Curves Of Motor Proteins Cooperating In Vivo, David A. Dewitt, T. Cahyuti, B. Townsend, J.C. Macosko, Y. Shtridelman

Faculty Publications and Presentations

Motor proteins convert chemical energy into work, thereby generating persistent motion of cellular and subcellular objects. The velocities of motor proteins as a function of opposing loads have been previously determined in vitro for single motors. These single molecule "force-velocity curves" have been useful for elucidating motor kinetics and for estimating motor performance under physiological loads due to, for example, the cytoplasmic drag force on transported organelles. Here we report forcevelocity curves for single and multiple motors measured in vivo. Using motion enhanced differential interference contrast (MEDIC) movies of living NT2 (neuron-committed teratocarcinoma) cells at 37°C, three parameters were measured-velocity …


The Biogeochemical Influences Of Nitrate, Dissolved Oxygen, And Dissolved Organic Carbon On Stream Nitrate Uptake, Joseph A. Thouin Jan 2008

The Biogeochemical Influences Of Nitrate, Dissolved Oxygen, And Dissolved Organic Carbon On Stream Nitrate Uptake, Joseph A. Thouin

Master's Theses and Capstones

Streams are important hotspots for the retention and removal of nitrogen (N), an element that contributes to eutrophication and threatens the stability of coastal ecosystems. Nitrate (NO3-) is the most mobile form of N, and understanding the causal mechanisms that foster optimal NO3- retention and removal in stream systems is critical from both predictive and conservation standpoints. Dissolved organic carbon (DOC) is hypothesized to be a major control of instream NO 3- concentrations, but dissolved oxygen (DO) is also an important control of NO3- removal processes. Assessing the individual impacts of NO3-, DO, and DOC concentrations on stream NO3- removal …


Has The Hiv Epidemic Peaked?, John Bongaarts, Thomas Buettner, Gerhard Heilig, Francois Pelletier Jan 2008

Has The Hiv Epidemic Peaked?, John Bongaarts, Thomas Buettner, Gerhard Heilig, Francois Pelletier

Poverty, Gender, and Youth

This working paper reviews the highly diverse regional and country patterns of HIV epidemics and discusses possible causes of the geographic variation in epidemic sizes. The main finding of this analysis is that the HIV epidemic reached a major turning point over the past decade. The peak years of HIV incidence rates are past for all regions, and the peaks of prevalence rates are mostly in the past except in Eastern Europe, where it is expected to peak in 2008. But owing in part to the life-prolonging effect of antiretroviral therapy and to sustained population growth, the absolute number of …


Synergistic Surfactant Interactions And The Consequences On Phase Behavior, Interfacial Tension Reduction And Hydrophobic Surface Wetting, Makonnen Mateós Payne Jan 2008

Synergistic Surfactant Interactions And The Consequences On Phase Behavior, Interfacial Tension Reduction And Hydrophobic Surface Wetting, Makonnen Mateós Payne

Dissertations, Theses, and Capstone Projects

The ability for some of the nonionic trisiloxane surfactants to completely and rapidly wet a hydrophobic surface has been well documented for several years. However, to date, the behavior of the trisiloxane surfactants at the solid-liquid interface is not yet completely understood, leading to an incomplete understanding of the mechanism for complete wetting. In this work we report our findings with regard to the synergistic interactions between polyethylene oxide surfactants of the general structure CiE j and compare the behavior to a known super wetting surfactant. Pendant drop tensiometry experiments and sessile drop contact angle measurements on hydrophobic surfaces were …

Markers Of Dyslexia In Adult Spanish-Speakers Who Report Severe Difficulty Learning English, Elizabeth Ijalba Jan 2008

Markers Of Dyslexia In Adult Spanish-Speakers Who Report Severe Difficulty Learning English, Elizabeth Ijalba

Dissertations, Theses, and Capstone Projects

The relationship between native-language reading ability and second-language (L2) learning was explored in a cohort of 60 adult Spanish-speakers learning English as a second language. The research questions centered on whether underlying nativelanguage deficits associated with dyslexia would be present in a subset of English Language Learners who reported severe difficulty learning English. Our participants were divided into two education groups (below and above12th grade). These two groups were classified into three groups based on self- and teacher- ratings of ease or difficulty in English learning ability: for the high-education group, Poor English Language Learners (PELL, N=7); Good English Language …


Technology And Signal Processing For Brain-Machine Interfaces, Justin C. Sanchez, Jose C. Principe, Toshikazu Nishida, Rizwan Bashirullah, John G. Harris, José A.B. Fortes Jan 2008

Technology And Signal Processing For Brain-Machine Interfaces, Justin C. Sanchez, Jose C. Principe, Toshikazu Nishida, Rizwan Bashirullah, John G. Harris, José A.B. Fortes

Electrical and Computer Engineering Faculty Research & Creative Works

Brain-machine interfaces (BMIs) aid disabled humans. BMI systems face challenges such as interfacing with neural tissue, selecting the most appropriate control signals, acquiring data and decoding patient intent in implantable or wearable computers. They must be able to adapt to different variety of behavioral states. Today's hybrid BMI systems consume less power and are made to chronically extract control commands from the nervous system. In terms of signal processing approaches, one challenge for BMI data analysis is learning how to handle large multi-input multi-output systems with signal representations that span continuous and discrete time. BMI systems also need sufficient information …


Softly, Softly Catchee Monkey: Informalism And The Quiet Development Of International Space Law, Gérardine Meishan Goh Jan 2008

Softly, Softly Catchee Monkey: Informalism And The Quiet Development Of International Space Law, Gérardine Meishan Goh

Nebraska Law Review

Questioning the juristic legitimacy of informalism and international soft law is not new. Despite the prevailing skepticism, the hard truth is that States and other actors on the international plane have always involved various methods of supplementing and avoiding legal obligations. The burgeoning ranks of stakeholders on the international level need international regulation to provide a consistent framework on which to base their activities. Where the traditional methods of international treaty-making have proven insufficiently efficient or up-to-date, recourse to informalism and soft law methods has provided the panacea.

This Article looks at the role of informalism and soft law in …


Why Resilience May Not Always Be A Good Thing: Lessons In Ecosystem Restoration From Glen Canyon And The Everglades, Sandi Zellmer, Lance Gunderson Jan 2008

Why Resilience May Not Always Be A Good Thing: Lessons In Ecosystem Restoration From Glen Canyon And The Everglades, Sandi Zellmer, Lance Gunderson

Nebraska Law Review

In this Article, we focus on three elemental ingredients. The first is the emerging system property of resilience, a concept that describes a more complex model of change and restoration than typical resource management goals related to maximizing social uses and achieving optimum yields of resource outputs. Resilience is a characteristic of both social and ecological systems. Resilience theory suggests that complex systems can exist in fundamentally different regimes, and resilience is the property that mediates transitions among those regimes. Hence resilience must be overcome when undertaking objectives that involve regime changes, such as an ecological restoration or a social …


Stumbling Toward Success: A Story Of Adaptive Law And Ecological Resilience, Mary Jane Angelo Jan 2008

Stumbling Toward Success: A Story Of Adaptive Law And Ecological Resilience, Mary Jane Angelo

Nebraska Law Review

For decades, scientific and legal scholars alike have promoted the concept of "adaptive management" as a necessary approach to meaningful environmental management, restoration, and regulation. Unfortunately, adaptive management success stories are few and far between. The Lake Apopka Restoration Project provides a real-world illustration of adaptive management at work. In this Article, I use adaptive management theory to explore mechanisms to make environmental law better able to address the uncertainties and changing nature of natural systems to restore and protect ecological resilience using the Lake Apopka restoration project as a case study. The case study involves more than fifty years …


Understanding Indigenous Canadian Traditional Health And Healing, (Gus) Louis Paul Hill Jan 2008

Understanding Indigenous Canadian Traditional Health And Healing, (Gus) Louis Paul Hill

Theses and Dissertations (Comprehensive)

This qualitative research study is situated within an Indigenous research methodology. The goal of the research was to develop an in-depth understanding of traditional healing from the perspectives of practitioners of traditional healing. It was important to explore the experiences of practitioners of traditional healing because there continues to be a lack of literature on this subject, as well as a significant lack of understanding and awareness about traditional healing and Indigenous Canadian people in mainstream society. The theoretical underpinnings of this research are holism and the four aspects of the self, visually represented in the Anishnaabe medicine wheel.

In-depth …


Hydrological Response Patterns And Solute Flux In Canadian Shield Basins: Role Of Different Physical Features And Antecedent Moisture Conditions, Jessica Mueller Jan 2008

Hydrological Response Patterns And Solute Flux In Canadian Shield Basins: Role Of Different Physical Features And Antecedent Moisture Conditions, Jessica Mueller

Theses and Dissertations (Comprehensive)

Patterns of stream flow in relatively undisturbed Canadian Shield basins are closely linked to their physical and vegetative characteristics and meteorological conditions. The physical characteristics include topography, soil-till composition, depth and structure, slope morphology and bedrock geology. Hydrological flowpaths through, and in-situ chemical processes in the soil-till matrix are influenced greatly by the composition of these features and by the antecedent hydrological conditions preceding a given storm or snowmelt event.

A long term data set, collected by the Dorset Environmental Science Centre, is used to examine eight forested basins within the Muskoka-Haliburton region of south-central Ontario. The basins have a …


The Role Of Race In Dna Statistics: What Experts Say, What California Courts Allow, David H. Kaye Jan 2008

The Role Of Race In Dna Statistics: What Experts Say, What California Courts Allow, David H. Kaye

Faculty Scholarship

When a defendant's DNA matches a sample found at a crime scene, how compelling is the match? To answer this question, DNA analysts typically use numbers - "relative frequencies," "random match probabilities" or "likelihood ratios." They compute and present these quantities for the major racial or ethnic groups in the United States, supplying prosecutors with such mind-boggling figures as "one in nine hundred and fifty sextillion African Americans, one in one hundred and thirty septillion Caucasians, and one in nine hundred and thirty sextillion Hispanics."

A line of California cases rejects this established practice on relevance grounds. The theory of …

Towards A Land Conservation Ethic In Zimbabwe: An Ethical And Religio-Cultural Analysis Of Land Conservation Policies And Practices In Communal Areas, Maaraidzo Elizabeth Mutambara Jan 2008

Towards A Land Conservation Ethic In Zimbabwe: An Ethical And Religio-Cultural Analysis Of Land Conservation Policies And Practices In Communal Areas, Maaraidzo Elizabeth Mutambara

Electronic Theses and Dissertations

In this study I analyze the problem of land degradation in Zimbabwe's Communal Areas (CAs) from the viewpoint of the Shona of Zimbabwe with the aim to formulate a land conservation ethic that motivates people in CAs to promote ecological stability. The Shona in CAs are proximate agents as well as victims of environmental degradation. The imperative to survive in a situation characterized by drastic inequalities in the allocation of land and an exploitative global economic system, forces them to engage in unsustainable land use practices. Land conservation policies in Zimbabwe marginalize Shona values and norms, especially as they relate …


Living Out: A Study Exploring The Experience Of Live Out Assistants In L’Arche, Jennifer Christine Elkins Jan 2008

Living Out: A Study Exploring The Experience Of Live Out Assistants In L’Arche, Jennifer Christine Elkins

Theses and Dissertations (Comprehensive)

The purpose of this research project was to qualitatively explore the experiences of live-out assistants in two L’Arche communities in order to better understand what these staff members perceived to be the benefits and challenges of community life in L’Arche. Live-out assistants support individuals with developmental disabilities in L’Arche communities, but do not live in a L’Arche home. This study incorporates theories related to the role of core values in uniting intentional communities and organizational change. Intentional communities face an ongoing challenge of adapting to internal and external changes, while retaining core values and a common purpose. An empowerment approach …


Evaluating Community Participation In Health Care Decision-Making: The Case Of The Airdie/North Rocky View Health Needs Project, Aleisha Dawn Harrington Jan 2008

Evaluating Community Participation In Health Care Decision-Making: The Case Of The Airdie/North Rocky View Health Needs Project, Aleisha Dawn Harrington

Theses and Dissertations (Comprehensive)

Rising health care costs combined with limited health resources have made it essential for health agencies around the world to identify successful and affordable ways to prevent disease and promote health. Several national and international documents have proposed that increased community participation in health matters is one potential approach. While many of these reports detail the benefits of and need for community participation in health care decision-making, they provide little information as to how this should be achieved. The result has been a myriad of interpretations, interventions and practices of community participation. According to several scholars, evaluations are needed that …


Paleohydrologic Reconstruction Of Three Shallow Basins, Slave River Delta, Nwt, Using Stable Isotope Methods, Cherie Mongeon Jan 2008

Paleohydrologic Reconstruction Of Three Shallow Basins, Slave River Delta, Nwt, Using Stable Isotope Methods, Cherie Mongeon

Theses and Dissertations (Comprehensive)

p>The long-term natural hydrological variability of the Slave River Delta (SRD), NWT, is not well documented and needs to be further developed to provide temporal context to understand and evaluate impacts of Slave River (SR) floodwater influence and climate variability and change on contemporary hydro-ecological doncidiotns of the SRD. The SRD has broad ecological and cultural significance, as it provides extensive habitate for wildlife and is important for local First Nations community who have an historical connection with the delta and its resources. Concners have been raised over recently reported drying trends in the SRD over the past few …


Pigeons’ Memory For Time: Assessment Of The Role Of Subjective Shortening In The Duration Of Comparison Procedure, Patrick Van Rooyen Jan 2008

Pigeons’ Memory For Time: Assessment Of The Role Of Subjective Shortening In The Duration Of Comparison Procedure, Patrick Van Rooyen

Theses and Dissertations (Comprehensive)

In Experiment 1, pigeons were trained with a 1-s baseline s-c delay in a duration comparison procedure to peck one key if a comparison duration (c) was 1-s shorter than a standard duration (s), and another key if c was 1-s longer than s. The duration pairs used prevented pigeons from relying on the absolute duration of c on some trials (comparison common) while on other trials they could rely on the absolute duration of c (comparison unique). Pigeons were then tested with equal duration pairs at extended s-c delays of 1, 2, 4, and …

The Human Activity-Travel Rescheduling Decision Process, Andrew F. Clark Jan 2008

The Human Activity-Travel Rescheduling Decision Process, Andrew F. Clark

Theses and Dissertations (Comprehensive)

Over the past few decades the activity scheduling decision process has become an important topic for transportation researchers, including how people reschedule their daily activities and travel in reaction to change. Rescheduling decisions include modifications/updates to timing, location/route, involved persons, event/mode type, and other attributes of activities/trips, as well as addition and deletion of completely new events. Such decisions occur as part of an ongoing process over time, space and across individuals. This thesis developed and applied a new data collection methodology for exploring the rescheduling decision process. The methodology had four main stages: capturing preplanned schedules; Global Positioning System …


Opportunity, Tools And Support: Ngo Engagement In The Security And Disarmament Field, Sarah Estabrooks Jan 2008

Opportunity, Tools And Support: Ngo Engagement In The Security And Disarmament Field, Sarah Estabrooks

Theses and Dissertations (Comprehensive)

NGOs have been consistently excluded from multilateral proceedings in the security and disarmament sector where states are concerned about their national security interests. And yet, they have found avenues to participate in the multilateral process through the negotiation of treaties, provision of expert research and testimony, systematic monitoring of state compliance, documentation of UN proceedings, and even as members of government delegations. This paper explores the conditions that enable NGOs to engage directly in the state-centric system of the United Nations, addressing political opportunity, enabling resources, and institutional support. I explore how NGOs contribute to international politics, using a constructivist …


Personal Stories Of Empathy In Adolescence And Emerging Adulthood, Kendall M. Soucie Jan 2008

Personal Stories Of Empathy In Adolescence And Emerging Adulthood, Kendall M. Soucie

Theses and Dissertations (Comprehensive)

Empathy, the ability to understand and experience the emotions of others, has yet to be investigated from a narrative or life story perspective. The purpose of the present study was, therefore, to examine the ways in which emerging adults and adolescents, through their self-defining stories, process and come to extract meaning from their personal empathic and non-empathic experiences. Twenty-nine adolescents (14–17, M=15.28, SD=.99), and 31 emerging adults (18–20, M=18.23, SD=.56) narrated stories about their empathic (times when they felt sad for someone, times when they put themselves in someone else’s shoes) and non-empathic experiences (times when …


Evaluation Of The Effects Of Various Exercise Interventions On Parkinson’S Disease, Michael D. Sage Jan 2008

Evaluation Of The Effects Of Various Exercise Interventions On Parkinson’S Disease, Michael D. Sage

Theses and Dissertations (Comprehensive)

The overall purpose of the current thesis was to evaluate the influence of various exercise strategies on Parkinson’s disease (PD). While countless exercise interventions have been investigated by PD, results have been weak and inconclusive at best. As such, there are currently no scientifically-validated recommendations for an optimal exercise intervention. The four studies comprising this thesis have attempted to address the shortcomings of previous literature, namely, inconsistent use of outcome measures, lack of PD symptomatic measures, varying lengths of exercise interventions, absence of a non-exercise control group, continued assessment of participants after exercise has ended, and verifying replicabilty of findings. …


Ashes To Ashes: Comparative Law Regarding Survivors’ Disputes Concerning Cremation And Cremated Remains, Eloisa Rodriguez-Dod Jan 2008

Ashes To Ashes: Comparative Law Regarding Survivors’ Disputes Concerning Cremation And Cremated Remains, Eloisa Rodriguez-Dod

Faculty Publications

One should plan for unassuming post-mortem issues, as most state laws do not provide a complete framework when there is no testamentary instruction by the deceased. Judicial determination is often needed, however reported opinions are scarce. Final disposition issues also arise in foreign law. Spain has no civil code regarding disposition of a deceased but delegates its funerary laws to local governments and autonomous communities, while the French have established an order of priority for funerary decisions and provide for a judicial determination and stay of the funerary process in case of dispute.

The author gives a brief history of …

Emergent Behavior In Massively-Deployed Sensor Networks, Ekaterina Shurkova, Ruzana Ishak, Stephan Olariu, Shaharuddin Salleh Jan 2008

Emergent Behavior In Massively-Deployed Sensor Networks, Ekaterina Shurkova, Ruzana Ishak, Stephan Olariu, Shaharuddin Salleh

Computer Science Faculty Publications

The phenomenal advances in MEMS and nanotechnology make it feasible to build small devices, referred to as sensors that are able to sense, compute and communicate over small distances. The massive deployment of these small devices raises the fascinating question of whether or not the sensors, as a collectivity, will display emergent behavior, just as living organisms do. In this work we report on a recent effort intended to observe emerging behavior of large groups of sensor nodes, like living cells demonstrate. Imagine a massive deployment of sensors that can be in two states "red" and "blue". At deployment time …

Biological, Serological, And Molecular Characterization Of Citrus Tristeza Virus Isolates From Different Citrus Cultivation Regions Of Turkey, Savaş Korkmaz, Bayram Çevi̇k, Serkan Önder, N. Kemal Koç

Turkish Journal of Agriculture and Forestry

Field surveys were carried out in 5 different citrus cultivation regions of Turkey in 2005 and 2006, and 201 samples were collected from different citrus species. Samples were tested for the presence of Citrus tristeza virus (CTV) by double antibody sandwich-enzyme-linked immunosorbent assay (DAS-ELISA) and reverse transcription-polymerase chain reaction (RT-PCR). While DAS-ELISA showed that 41 trees were infected with CTV, an additional 13 trees were found to be positive based on RT-PCR. When CTV-positive samples were tested with the Western blot method using the monoclonal antibody MCA13, which is specific to severe isolates of CTV, 32 isolates, mostly from satsuma, …
