The Highest Mountain - T-Cell Technology
No full textYesT-lymphocytes (T-cell) therapy offers a treatment for cancers. Developing this technology in the future provides the opportunity to revolutionise treatment and to make cancer a chronic condition. T-cells in themselves are a type of lymphocytes (itself a type of white blood cell) that play a central role in cell mediated immunity. They can be distinguished from other lymphocytes, such as B-cells and natural killer cells (NK cells), by the presence of a T-cell receptor (TCR) on the cell surface. T-cells have the capacity to destroy diseased cells, but tumours present a considerable challenge that reduces their impact. As cancer cells are frequently ‘invisible’ to the immune system, and they create an environment that suppresses T-cell activity., genetic engineering of T-cells can be used therapeutically to overcome these challenges. T-cells can be taken from the blood of cancer patients and then modified to recognise and destroy cancer-specific antigens

Obstacles on the path: An exposition of the experience of car-free living
No full textThe contemporary focus by local and central government on the promotion of sustainable transport options has highlighted the need for commuting to move away from the current dependence on private cars to more public and active (walking and cycling) modes of transport. Given the prominence of the motor car in personal transport options however, choosing to live car-free in this car dependent culture appears at first glance to be an irrational choice. This research explores the lived experiences of a group of Hamilton residents who have made such a choice. Using a grounded theory approach, the thesis presents the results of interviews with nine car-free Hamilton residents who shared their personal transport stories, which include their childhood experiences, but focus on their current everyday practices and experiences. Through semi-structured interviews, the costs and benefits of a car-free lifestyle are articulated and analysed. Their motivations for choosing to forgo cars and their solutions for overcoming potential barriers to car-free living are also reported and explored. The collected data generated a range of themes which are presented in three chapters, each covering a specific aspect of the participants’ stories. The first group of themes relate to the public sphere, the second to the private realm and the final group emanates from specific elements of car-free living that the thesis sought to clarify through the participants’ stories. The key finding is that living car-free within Hamilton City is viewed by the participants as a well reasoned and eminently sensible choice, which produces multiple benefits. In addition to their reduced environmental footprints, the participants value the social interaction associated with active and public transport. Their consensus is that they are healthier, wealthier and more involved members of the community. The most problematic areas of living without a car were associated with recreational and social activities, which often do not coincide with public transport schedules or involve distances too great for active transport. The benefits far outweigh any disadvantages however, and ultimately, this thesis concludes that a motor car is not necessary for the everyday activities of urban living in Hamilton and any associated inconveniences are not as insurmountable as generally imagined
Integrating climate change into Northeast and Midwest state wildlife action plans
No full textThe purpose of this Northeast Climate Science Center-led (NE CSC) cooperative report is to provide a synthesis of what is known and what is uncertain about climate change and its impacts across the NE CSC region, with a particular focus on the responses and vulnerabilities of Regional Species of Greatest Conservation Need (RSGCN) and the habitats they depend on. Another goal is to describe a range of climate change adaptation approaches, processes, tools, and potential partnerships that are available to State natural resource managers across the Northeast and Midwest regions of the United States. Through illustrative case studies submitted by the NE CSC and partners, the report discusses climate change adaptation efforts being explored and implemented across local and large-landscape scales.The suggested citation for this report is: Staudinger, M.

Systematic Review and Empirical Comparison of Contemporaneous EQ-5D and SF-6D Group Mean Scores
No full text Background. Group mean estimates and their underlying distributions are the focus of assessment for cost and outcome variables in economic evaluation. Research focusing on the comparability of alternative preference-based measures of health-related quality of life has typically focused on analysis of individual-level data within specific clinical specialties or community-based samples. Purpose. To explore the relationship between group mean scores for the EQ-5D and SF-6D across the utility scoring range. Methods. Studies were identified via a systematic search of 13 online electronic databases, a review of reference lists of included papers, and hand searches of key journals. Studies were included if they reported contemporaneous mean EQ-5D and SF-6D health state scores. All (sub)group comparisons of group mean EQ-5D and SF-6D scores identifiable from text, tables, or figures were extracted from identified studies. A total of 921 group mean comparisons were extracted from 56 studies. The nature of the relationship between the paired scores was examined using ranked scatter graphs and analysis of agreement. Results. Systematic differences in group mean estimates were observed at both ends of the utility scale. At the lower (upper) end of the scale, the SF-6D (EQ-5D) provides higher mean utility estimates. Conclusions. These findings show that group mean EQ-5D and SF-6D scores are not directly comparable. This raises serious concerns about the cross-study comparability of economic evaluations that differ in the choice of preference-based measures, although the review focuses on 2 of the available instruments only. Further work is needed to address the practical implications of noninterchangeable utility estimates for cost-per-QALY estimates and decision making. </jats:p
Patients' preferences for the management of non-metastatic prostate cancer: discrete choice experiment
No full textObjective To establish which attributes of conservative treatments for prostate cancer are most important to men. Design Discrete choice experiment. Setting Two London hospitals. Participants 129 men with non-metastatic prostate cancer, mean age 70 years; 69 of 118 (58%) with T stage 1 or 2 cancer at diagnosis. Main outcome measures Men's preferences for, and trade-offs between, the attributes of diarrhoea, hot flushes, ability to maintain an erection, breast swelling or tenderness, physical energy, sex drive, life expectancy, and out of pocket expenses. Results The men's responses to changes in attributes were all statistically significant. When asked to assume a starting life expectancy of five years, the men were willing to make trade-offs between life expectancy and side effects. On average, they were most willing to give up life expectancy to avoid limitations in physical energy (mean three months) and least willing to trade life expectancy to avoid hot flushes (mean 0.6 months to move from a moderate to mild level or from mild to none). Conclusions Men with prostate cancer are willing to participate in a relatively complex exercise that weighs up the advantages and disadvantages of various conservative treatments for their condition. They were willing to trade off some life expectancy to be relieved of the burden of troublesome side effects such as limitations in physical energy
Application of Phase Change Materials for Building Energy Retrofits in a Hot Arid Climate
No full textabstract: In 2018, building energy use accounted for over 40% of total primary energy consumption in the United States; moreover, buildings account for ~40% of national CO2 emissions. One method for curbing energy use in buildings is to apply Demand Side Management (DSM) strategies, which focus on reducing the energy demand through various technological and operational approaches in different building sectors.
This PhD research examines the integration of DSM strategies in existing residential and commercial buildings in the Phoenix, Arizona metropolitan area, a hot-arid climate. The author proposes three different case studies to evaluate the effectiveness of one DSM strategy in buildings, namely the integration of Phase Change Materials (PCMs). PCMs store energy in the freezing process and use that stored energy in the melting process to reduce the energy demand. The goal of these case studies is to analyze the potential of each strategy to reduce peak load and overall energy consumption in existing buildings.
First, this dissertation discusses the efficacy of coupling PCMs with precooling strategies in residential buildings to reduce peak demand. The author took a case study approach and simulated two precooling strategies, with and without PCM integration, in two sample single-family homes to assess the impact of the DSM strategies (i.e., precooling and PCM integration) on load shifting and load shedding in each home.
Second, this research addresses the feasibility of using PCMs as sensible and latent heat storage in commercial buildings. The author documents the process of choosing buildings for PCM installation, as well as the selection of PCMs for retrofitting purposes. Commercial building case studies compare experimental and simulation results, focusing on the impact of the PCMs on reducing the total annual energy demand and energy cost.
Finally, this research proposes a novel process for selecting PCMs as energy efficiency measures for building retrofits. This process facilitates the selection of a building and PCM that are complementary. Implementation of this process has not yet been tested; however, the process was developed based on experimental and simulation results from prior studies, and it would alleviate many of the PCM performance issues documented in those studies.Dissertation/ThesisDoctoral Dissertation Civil, Environmental and Sustainable Engineering 202
More Mirrors, Windows, and Sliding Doors: A Period of Growth in African American Young Adult Literature (2001 to 2021)
No full textBryan Ripley Crandall is a contributing author, \u27As In\u27 An Award Winning Writer: Kwame Alexander, chapter 4, pp.33-44.
This is the third book in a three volume series celebrating and examining about the work of 11 of the most prominent African American authors since 2000. The eleven identified authors are Andrea Davis Pinkney, Coe Booth, Sheila P. Moses, Kwame Alexander, Kekla Magoon, Jason Reynolds, Varian Johnson, Renee Watson, Tiffany D. Jackson, Nnedi Okorafor, and Lamar Giles. These authors build on the work of the authors in books two and three. The chapter authors—librarians and established and emerging scholars in the field of young adult literature--survey the work of each author, their accolades, and how audiences responded to their work. Each chapter highlights a single work and discusses how it might be taught in a classroom with a focus on introductory, during, and concluding activities for individuals, small groups and the whole class. This volume is a resource for classroom teachers, teacher educators, reading specialists, librarians, and other educators who study, research, and read young adult literature. Even more importantly it can be resource for students who read and study these authors at the secondary and collegiate level. This is especially true when the current moment in the U. S. shows facing anew concerns of voting rights and discussion of how and when Critical Race Theory or any discussion of Race might take place in a classroom.https://digitalcommons.fairfield.edu/education-books/1069/thumbnail.jp
