    It is difficult to know what to make of The Life of Okah Tubbee because it is difficult to know what to make of Okah Tubbee. In the 1840s and 1850s he was a performing musician, a ventriloquist, and an Indian doctor. He claimed to be a Choctaw chief’s son who, somehow, had begun life as a slave in Natchez, Mississippi. His autobiography, possibly written by his wife (possibly of Delaware and Mohawk extraction), appeared in several formats and editions in 1848 and 1852

    A once and future extractive history of Britain

    Get PDF
    Geology, geography and human affairs have combined to give Britain a rich history of mineral extraction which stretches back several thousand years. Changing technological, economic and social factors means that the character and scale of domestic extraction have varied enormously over this time span. These same factors have also influenced our level of trade in minerals and metals with the rest of the world. Cornish tin established Britain as a supplier of metal across the ancient world. Norman masons utilised huge quantities of dimension stone to build cathedrals and castles. Wooden ships sheathed with copper from South West England, Wales and the Lakes secured a global empire for Britain in the 17th and 18th Century. Indigenous coal and iron were the basis of Victorian and Edwardian prosperity. Aggregates for road building literally formed the foundation of the post-war ‘great car economy’. Economic globalisation, technology shift and changes in societal attitudes in the late 20th and early 21st Century caused a precipitous decline in domestic output of some minerals, notably metals and coal. The British seemed content to let the global market provide their material needs and happy to export the impacts of mineral extraction to other countries. However, by 2050 it is likely that human population will be close to 9 billion, economic power will have shifted from the West, environmental change will be accelerating and global competition for resources will be intense. In the face of this enormous challenge, will indigenous minerals make a comeback and increase their contribution to our security and prosperity

    SASICE: Safety and sustainability in civil engineering

    The performance of the built environment and the construction sector are of major importance in Europe’s long term goals of sustainable development in a changing climate. At the same time, the quality of life of all European citizens needs to be improved and the safety of the built environment with respect to man-made and natural hazards, such as flooding and earthquakes, needs to be ensured. Education has a central role to play in the transformation of a construction sector required to meet increasing demands with regard to safety and sustainability. In this work, the SASICE project is presented. The aim of this project is to promote the integration of safety and sustainability in civil engineering education. The project is organised in the context of the Lifelong Learning Programme, funded by the European Community. The coordinator organisation is the University of Bologna. Nine partner universities from different countries are involved in this transnational project. The universities participating to the project constitute a network of high level competences in the civil engineering area, with several opportunities to improve lifelong learning adopting different media: joint curricula, teaching modules and professor and student exchanges. As a response to the challenge regarding new educational methods in sustainable engineering, teaching modules are developed in 4 thematic areas: (1) Safety in construction, (2) Risk induced by Natural Hazards Assessment, (3) Sustainability in construction, and (4) Sustainability at the territorial level. The development of the teaching modules is based on an extensive analysis of the need for highly qualified education on Safety and Sustainability involving all relevant stakeholders (European and national authorities, companies, research institutes, professional organizations, and universities).The main target is enabling students to introduce these advanced topics in their study plans and curricula and reach, at the end of their studies, a specific skill and expertise in safety and sustainability in Civil Engineering. With our natural resources fading away and our infrastructure in dire need of repair, new trends and challenges in civil engineering education in the concept of “Sustainable Development” are needed to be adressed.<br/

    Energy dependence of {\rm K}S0^0_{\rm S} and hyperon production at CERN SPS

    Full text link
    Recent results on KS0^0_{\rm S} and hyperon production in Pb-Pb collisions at 40 and 158 AA GeV/cc beam momentum from the NA57 experiment at CERN SPS are presented. Yields and ratios are compared with those measured by the NA49 experiment, where available. The centrality dependence of the yields and a comparison with the higher collision energy data from RHIC are discussed.Comment: 4 pages, 3 figures, proceedings of QM2004 conferenc

    The Mississippi delta health collaborative medication therapy management model: Public health and pharmacy working together to improve population health in the Mississippi delta

    © 2020. Introduction The Mississippi Delta has high rates of chronic disease and is known for its poor health outcomes and health disparities. University of Mississippi School of Pharmacy (UMSOP) and the Mississippi State Department of Health partnered in 2009 through the Mississippi Delta Health Collaborative to reduce health disparities and improve clinical outcomes by expanding the UMSOP\u27s evidence-based medication therapy management (MTM) initiative, focused in Mississippi\u27s 18-county Delta region, to federally qualified health centers (FQHCs) in 4 of those counties. Methods Between January 2009 and August 2018, the MTM initiative targeted FQHC patients aged 18 years or older with a diagnosis of diabetes, hypertension, and/or dyslipidemia. Pharmacists initially met face-to-face with patients to review all medications, provide education about chronic diseases, identify and resolve drug therapy problems, and take appropriate actions to help improve the effectiveness of medication therapies. Clinical parameters evaluated were systolic blood pressure (SBP), diastolic blood pressure (DBP), total cholesterol, low-density lipoprotein (LDL) cholesterol, triglycerides, and hemoglobin A1c (HbA1c). Results The analysis included 335 patients with hypertension (n = 287), dyslipidemia (n = 131), and/or diabetes (n = 331). Significant mean reductions occurred in the following metrics: SBP (7.1 mm Hg), DBP (6.3 mm Hg), LDL cholesterol (24.9 mg/dL), triglycerides (45.5 mg/dL), total cholesterol (37.7 mg/dL), and HbA1c (1.6% [baseline ≄6%] and 1.9% [baseline ≄9%]). Conclusion Despite the cultural and environmental disadvantages present in the Mississippi Delta, the integrated MTM treatment program demonstrated significant health improvements across 3 chronic diseases: hypertension, dyslipidemia, and diabetes. This model demonstrates that a partnership between public health and pharmacy is a successful and innovative approach to care

    New results from the NA57 experiment

    Full text link
    We report results from the experiment NA57 at CERN SPS on hyperon production at midrapidity in Pb-Pb collisions at 158 AA GeV/cc and 40 AA GeV/cc. Λ\Lambda, Ξ\Xi and Ω\Omega yields are compared with those from the STAR experiment at the higher energy of the BNL RHIC. Λ\Lambda, Ξ\Xi, Ω\Omega\ and preliminary KS0K_S^0 transverse mass spectra are presented and interpreted within the framework of a hydro-dynamical blast wave model.Comment: 8 pages, 3 figures, contribution to the proceedings of The XXXVIIIth Rencontres de Moriond "QCD and High Energy Hadronic Interactions

    Strangeness enhancements at central rapidity in 40 A GeV/c Pb-Pb collisions

    Full text link
    Results are presented on neutral kaon, hyperon and antihyperon production in Pb-Pb and p-Be interactions at 40 GeV/c per nucleon. The enhancement pattern follows the same hierarchy as seen in the higher energy data - the enhancement increases with the strangeness content of the hyperons and with the centrality of collision. The centrality dependence of the Pb-Pb yields and enhancements is steeper at 40 than at 158 A GeV/c. The energy dependence of strangeness enhancements at mid-rapidity is discussed.Comment: 15 pages, 10 figures and 3 tables.

    Expansion dynamics of Pb-Pb collisions at 40 A GeV/c viewed by negatively charged hadrons

    Full text link
    In this paper we present results on transverse mass spectra and Hanbury-Brown and Twiss correlation functions of negatively charged hadrons, which are expected to be mostly negative pions, measured in Pb-Pb collisions at 40 A GeV/c beam momentum. Based on these data, the collision dynamics and the space-time extent of the system at the thermal freeze-out are studied over a centrality range corresponding to the most central 53% of the Pb--Pb inelastic cross section. Comparisons with freeze-out conditions of strange particles and HBT results from other experiments are discussed.Comment: 29 pages, 18 figure
