Temperature and food effects on larval Pacific herring (Clupea pallasi) in Prince William Sound, Alaska

Thesis (M.S.) University of Alaska Fairbanks, 2003The effects of food availability and water temperature on larval Pacific herring growth rates and survival were studied using a coupled biophysical model for 1993 through 1997. The herring growth model included feeding gains, metabolic costs, mortality losses and vertical migration of the herring larvae. In years when springtime oceanographic processes resulted in a high concentration of zooplankton, food availability did not limit larval herring growth rates; water temperature determined survival. However, in other years, food availability did limit survival, either due to insufficient food concentrations or to inaccessibility of the food. Vertical migration occasionally was restricted by strong water column stratification, which prevented the larvae from reaching food concentrations sufficient for growth. Thus the amount of food, the temperature, and the vertical distribution of the food and the larvae were found to affect growth. The study of vertical properties of factors affecting larval fish must be included in larval fish research

Importing Prison Labor Products from the People\u27s Republic of China: Re-examining U.S. Enforcement of Section 307 of the Trade and Tariff Act of 1930

Since 1989, the United States has engaged in a heated debate with the People\u27s Republic of China over products manufactured in Chinese prisons which enter U.S. markets. Human rights advocates argue that conditions in China\u27s prisons violate human rights principles, and therefore, the United States should not extend Most Favored Nation trade status to China. Others argue that human rights conditions will only improve if the United States continues to extend MFN privileges. Forgotten is section 307 of the Trade and Tariff Act of 1930, which prohibits imports of products made from prison labor. To effectively address the prison labor issue with China, the United States should remove the issue from the human rights debate and focus on improved enforcement of section 307

Prone Positioning in Acute Respiratory Distress Syndrome Patients

Introduction: Acute respiratory distress syndrome (ARDS), seen in critically ill patients, is a disease process that affects the lungs and directly impacts a patient’s oxygenation. Despite treatment, patients often die of ARDS secondary to systemic complications. Prone positioning has been introduced as a treatment to improve the outcomes of ARDS patients. This thesis summarized and critiqued recent literature on the outcomes of prone positioning in ARDS patients. Methodology: An initial literature search was conducted using CINAHL Plus with Text, Medline, Cochrane Database of Systematic Reviews, and US National Library of Medicine National Institutes of Health. Multiple search terms were used. Inclusion criteria consisted of peer reviewed research articles, academic journal articles, and evidence-based research or practices published within the last ten years. All studies included adult subjects and were published in the English language. Studies that did not address patient outcomes such as mortality, length of stay, or hemodynamic oxygenation were excluded from the review. Results: The review of literature contains one meta-analysis and two studies. Data indicated that prone positioning was statistically significant in reducing mortality when performed in sessions of 12 hours or longer (p=0.05). Hemodynamic oxygenation improved significantly after at least 48 hours of implementing prone positioning. There was no trend in the length of stay or duration in mechanical ventilation whether supine or prone positioning was used. Complications such as endotracheal tube dislodgement, incidence of ventilator-associated pneumonia, and pressure ulcers were reported in both supine and prone position with an increased risk of pressure ulcers and endotracheal tube obstruction in the prone position groups. Conclusions: Findings support a benefit in patient outcomes in patients placed in prone position with ARDS. Mortality was reduced when prone sessions lasted longer than 12 hours possibly due to the improvement in patient oxygenation 48 hours after initiation of prone positioning intervention. Further research is needed to solidify these findings and establish guidelines and optimal procedural methods to maximize patient outcomes and lower the incidence of patient complications

Factors Influencing Changes in Public Library Adult Programming: A Look at Program Practices in Two North Carolina Public Libraries

This study describes an examination of the history and current practices of adult programming in two North Carolina public libraries. The examination was conducted to determine the current state of adult programming in public libraries, as well as the factors that have influenced its changes. Public libraries have begun to offer more diverse types of adult programming for their patrons. For example, some categories of programming being offered that have recently grown in prevalence are Entertainment, Arts/Crafts, and Health. This is due to a combination of many factors, and reasons vary between communities. The most significant factor affecting the planning of adult programs is the preferences of an individual community. Librarians must take into account what their communities need and desire from the library in order to have successful programs.Master of Science in Library Scienc

Review of Residential Low-Load HVAC Systems

In support of the U.S. Department of Energy’s (DOE’s) Building America Program, Pacific Northwest National Laboratory (PNNL) conducted an investigation to inventory commercially available HVAC technologies that are being installed in low-load homes. The first step in this investigation was to conduct a review of published literature to identify low-load HVAC technologies available in the United States and abroad, and document the findings of existing case studies that have evaluated the performance of the identified technologies. This report presents the findings of the literature review, identifies gaps in the literature or technical understanding that must be addressed before low-load HVAC technologies can be fully evaluated, and introduces PNNL’s planned research and analysis for this project to address identified gaps and potential future work on residential low-load HVAC systems

A Collection of Case Studies on Financial Accounting Concepts

This thesis is compiled of twelve case studies, each on a unique accounting concept. Each case study was analyzed in a group of two to four students, and each student completed a write-up answering the case questions and examining the proper accounting treatment for each issue in the case. Case topics included financial statement assembly and analysis, internal controls, inventories, leases, revenue recognition, deferred income taxes, and examinations of equity, among others. Each topic was considered using accounting knowledge learned during intermediate accounting classes at the University of Mississippi as well as the Financial Accounting Standards Board (FASB) Codification. The codification explicitly states rules and regulations to follow when accounting for each item, and was very useful when considering unfamiliar and unusual topics presented in the cases. The case studies are arranged in chronological order of completion, and each is titled with a description of the case topic

Adaptive control of hydraulic shift actuation in an automatic transmission

Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering, 2013.Cataloged from PDF version of thesis.Includes bibliographical references (p. 79-80).A low-order dynamic model of a clutch for hydraulic control in an automatic transmission is developed by separating dynamics of the shift into four regions based on clutch piston position. The first three regions of the shift are captured by a physics-based model and the fourth region is represented by a system identification model. These models are determined using nominal values and validated against nominal and off-nominal experimental data. The model provides two lumped flow parameters to be used for tuning to the desired hydraulic clutch system. Using feedback information from the model and transmission mechanicals, a closed -loop adaptive controller is designed. The controller is structured to update at three different rates: every time instance, every shift, and every n-th number of shifts. Part of the controller is designed to operate in open-loop for the first two regions of the shift until feedback information is available. The open-loop controller adapts within the shift, thus allowing for corrections to the control design to be made in following shifts. The model tuning parameters as well as the main spring preload become the adaptive parameters, which are then adjusted so that the plant matches the model. The control design is validated against a high fidelity simulation model of the transmission hydraulics and mechanicals.by Sarah Marie Thornton.S.M
