    There exists broad scientific consensus that heatwaves are increasing in frequency, duration, and intensity in a warming world, and are generally the most strongly linked extreme weather event to anthropogenic climate change. Due to its predominantly maritime climate, few studies have examined heatwaves in Florida. However, Florida’s older-skewed population and increasingly urban land areas make it particularly susceptible to the impacts of heatwaves on human life and health in the twenty-first century. Using a percentile-based heatwave definition applied to station daily maximum, minimum, and average temperature data, trends in the frequency, intensity, and duration of heatwaves were investigated. In order to isolate the effect of Sea Surface Temperature (SST) on heatwaves, four major cities across the southeast were investigated and compared to six major cities on the Florida peninsula from 1950–2016. Initial results show that coastal southeast U.S. heatwave frequency and trends at locations such as New Orleans may be most similar to cities in the Florida peninsula, due in part to the proximity of warming SSTs. The most substantial trends, especially near large bodies of water, are found in minimum temperature heatwaves

    NEPA Review of Offshore Wind Farms: Ensuring Emission Reduction Benefits Outweigh Visual Impacts

    Get PDF
    Wind power may greatly reduce overall emissions of air pollutants from fossil fuel plants. Benefits could range from fewer premature deaths to reduced global warming, and cover the gamut of goals that the National Environmental Policy Act (NEPA) articulates. Previous NEPA reviews of wind projects, however, have focused on local aesthetic objections and given only cursory treatment to emission reductions. This imbalance threatens to frustrate, rather than further, NEPA’s goals. Beginning with the offshore wind farm proposed near Cape Cod, Massachusetts, reviewers must accord the prominence and depth of treatment to emission offset benefits that NEPA requires. Local aesthetic preferences must not be permitted to overshadow broad regional benefits

    Innovative Stormwater Treatment Technologies: Best Management Practices Manual

    Get PDF
    Urban stormwater carries a number of pathogens, nutrients, heavy metals, sediment, and other contaminants as surface runoff flows over land. The increase in impervious or paved surfaces associated with development in urban areas reduces the natural infiltration of precipitation into the ground. With impervious cover, precipitation collects and carries contaminants before draining into nearby surface waters. Stormwater runoff from paved surfaces in developed areas can degrade downstream waters with both contaminants and increased volumes of water. This publication aims to make information on innovative stormwater treatment technologies more available to New Hampshire’s urban planners, developers, and communities. Traditional runoff management techniques such as detention basins and infiltration swales may be preferable, but are not always practical for treating urban stormwater. Lack of space for natural solutions is often a problem in existing developed areas, making innovative treatment technologies an attractive alternative. Mostly designed for subsurface installation, urban “retrofits” use less space than conventional methods to treat stormwater. This manual provides information on the innovative stormwater “retrofit” technologies currently available for use in developed areas in New Hampshire

    Energetic Behavior of Resistive Random-Access Memory Cells

    Get PDF
    In order to investigate the switching characteristics of Resistive Random Access Memory cells (ReRAM) in terms of their thermodynamic free energy properties, we need to build a number of models that replicate the system. This report contains the models used to investigate filament growth patterns based on different boundary conditions applied to the electrode-filament system. Using Comsol Multiphysics software, we determined that when a fixed voltage is applied to each electrode in the electrode-filament system, we should expect filament dissolution that resets our cells into the High Resistance State (HRS). If we instead fix a set amount of charge on each electrode, we expect that filament growth will occur spontaneously, setting our cells into a Low Resistance State (LRS). This report also explores the balance between establishing a fixed voltage between the electrodes too quickly - where filament growth may not occur - while still optimizing the switching time of these cells with an applied voltage pulse

    Brexit and the Effects on European ADRs vs British ADRs

    Get PDF
    Using a collection of American Depositary Receipts (ADRs), this study examines the stock-price reaction of European, European Union, and British firms to the Brexit Referendum on June 23, 2016. Results show that non-European firms experienced greater returns than the market after the Brexit referendum. European, European Union, and British firms all experienced negative returns compared to the average market return. While at first glance British firms appeared to experience even greater negative returns as compared to firms in the European Union, overall there was no statistically significant difference between returns for firms in the European Union and firms in the United Kingdom. These results show that in the initial aftermath of the Brexit Referendum, investors believed that the non-European world would benefit from a weaker European Union, and that both the European Union and the United Kingdom were likely to adversely effected by the referendum

    The history of the South Side Railroad, 1846-1870

    Get PDF
    The South Side Rail Road, chartered in 1846, was the fourth railroad to serve the city of Petersburg, Virginia, and, upon its completion in 1854, was the only direct rail link the city had through the Virginia Piedmont to Lynchburg and points west. The railroad was a major conveyor of trade through the Southside region of Virginia and served as an engine of economic development for the area. During the Civil War the road was a vital means of transportation of men and materiel for the Confederate government. After the war, General William Mahone, a railroad professional and war hero, was elected president of the South Side. In 1870, he consolidated the road into his railroad empire, the Atlantic, Mississippi, and Ohio Railroad Company. This thesis examines the organization, construction, financing, and operation of the South Side Rail Road Company from its origin in 1846 to its merger in 1870. It has relied primarily upon such sources as the annual reports and business records of the company, newspaper and journal accounts, and journals, reports, and acts of the Virginia General Assembly

    Heart to Heart: A Cardiac Rehabilitation Follow-up Program

    Get PDF
    This dissertation describes a tele-health follow-up program designed to attend to the problem of noncompliance in the process of health-behavior change after formal Cardiac Rehabilitation treatment at a southern New Hampshire community hospital. Cardiac Rehabilitation treatment encompassing lifestyle behavior change is associated with a significant reduction in morbidity and mortality in individuals with Coronary Heart Disease. However, evidence that adherence to lifestyle behavior change recommendations diminishes significantly within six months of treatment suggests that noncompliance is a significant barrier to the secondary prevention of a disease with prodigious consequences. Accumulating evidence that Cardiac Rehabilitation treatment encompassing extended duration of contact with the treatment team is associated with long-term health-risk behavior change as well as significantly fewer clinical events provides rationale for development of this program. Consistent with the identified outpatient treatment program, the proposed aftercare program aims to achieve significant and sustained changes in risk-factor related lifestyle behavior areas. Based on the conceptualization that behavior change is an ongoing dynamic process that encompasses repeated cycles of relapse, the program provides ongoing telephone sessions over the first year after discharge from the outpatient program. The Transtheoretical Model of Change as it interacts with the principles of Motivational Interviewing provide the foundation for planning and facilitating interventions that are relevant to the patient during each contact. The RE-AIM Model guided the development and formative evaluation of the program. The proposed plan for summative program evaluation is based on guidelines provided by the American Association of Cardiovascular and Pulmonary Rehabilitation, and assesses outcomes in Health, Clinical, Behavioral and Service Domains. Barriers to implementation of the proposed program include financial issues as they interact with the necessity for provider training and the current economic environment that impedes the implementation of adjunct programs within the health-care system
