Grain Surface Models and Data for Astrochemistry

Abstract: The cross-disciplinary field of astrochemistry exists to understand the formation, destruction, and survival of molecules in astrophysical environments. Molecules in space are synthesized via a large variety of gas-phase reactions, and reactions on dust-grain surfaces, where the surface acts as a catalyst. A broad consensus has been reached in the astrochemistry community on how to suitably treat gas-phase processes in models, and also on how to present the necessary reaction data in databases; however, no such consensus has yet been reached for grain-surface processes. A team of ${\sim}25$ experts covering observational, laboratory and theoretical (astro)chemistry met in summer of 2014 at the Lorentz Center in Leiden with the aim to provide solutions for this problem and to review the current state-of-the-art of grain surface models, both in terms of technical implementation into models as well as the most up-to-date information available from experiments and chemical computations. This review builds on the results of this workshop and gives an outlook for future directions.

Tires, Suspension and Handling, Second Edition

Abstract: This book provides detailed coverage of the theory and practice of vehicle cornering and handling. Much of the material in this book is not available elsewhere, including unique information on suspension analysis, understeer/oversteer, bump steer and roll steer, roll centers, limit handling, and aerodynamics. Each chapter ends with a wide selection of problems, providing an ideal review. This book is an excellent resource for vehicle designers and engineering students who want to better understand and analyze the numerous factors affecting vehicle handling.

Improving the energy performance of UK households: Results from surveys of consumer adoption and use of low- and zero-carbon technologies

Abstract: This paper presents results from a UK Open University project which surveyed consumers’ reasons for adoption, and non-adoption, of energy efficiency measures and renewable energy systems—collectively called low- and zero-carbon technologies—and their experiences of using these technologies. Data were gathered during 2006 via an online questionnaire with nearly 400 responses, plus 111 in-depth telephone interviews. The respondents were mainly environmentally concerned, ‘green’ consumers and therefore these are purposive rather than representative surveys. The paper outlines results for four energy efficiency measures (loft insulation, condensing boilers, heating controls and energy-efficient lighting) and four household renewables (solar thermal water heating, solar photovoltaics, micro-wind turbines and wood-burning stoves). These green consumers typically adopted these technologies to save energy, money and/or the environment, which many considered they achieved despite rebound effects. The reasons for considering but rejecting these technologies include the familiar price barriers, but there were also other obstacles that varied according to the technology concerned. Nearly a third of the surveyed consumers had adopted household renewables, over half of which were wood stoves and 10% solar thermal water heating systems. Most adopters of renewables had previously installed several energy efficiency measures, but only a fifth of those who seriously considered renewables actually installed a system. This suggests sell energy efficiency first, then renewables. There seems to be considerable interest in household renewables in the UK, especially among older, middle-class green consumers, but so far only relatively few pioneers have managed to overcome the barriers to adoption.

Prevalence of depression in individuals with impaired glucose metabolism or undiagnosed diabetes: a systematic review and meta-analysis of the European Depression in Diabetes (EDID) Research Consortium

Abstract: OBJECTIVE Meta-analyses have shown that the risk for depression is elevated in type 2 diabetes. Whether this risk in individuals with impaired glucose metabolism (IGM) or undiagnosed diabetes (UDD) is elevated relative to normal glucose metabolism (NGM) or decreased relative to previously diagnosed type 2 diabetes (PDD) has not been the subject of a systematic review/meta-analysis. This study examined the prevalence of depression in IGM and UDD subjects relative to each other and to NGM and PDD subjects by reviewing the literature and conducting a meta-analysis of studies on this topic. RESEARCH DESIGN AND METHODS EMBASE and MEDLINE databases were searched for articles published up to May 2010. All studies that compared the prevalence of depression in subjects with IGM and UDD were included. Odds ratios (ORs) were calculated using fixed and random-effects models. RESULTS The meta-analysis showed that the risk for depression was not increased in IGM versus NGM subjects (OR 0.96, 95% CI 0.85–1.08). Risk for depression did not differ between individuals with UDD and individuals with either NGM (OR 0.94, 95% CI 0.71–1.25) or IGM (OR 1.16, 95% CI 0.88–1.54). Finally, individuals with IGM or UDD both had a significantly lower risk of depression than individuals with PDD (OR 0.59, 95% CI 0.48–0.73, and OR 0.57, 95% CI 0.45–0.74, respectively). CONCLUSIONS Results of this meta-analysis show that the risk of depression is similar for NGM, IGM, and UDD subjects. PDD subjects have an increased risk of depression relative to IGM and UDD subjects.

Conceptual Framework for Regional Competitiveness

Abstract: Budd L. and Hirmis A. K. (2004) Conceptual framework for regional competitiveness, Regional Studies38, 1007-1020. The concept of territorial competitiveness has gained ground in academic, policy and practitioner circles. In particular, urban competitiveness has generated a large literature. However, there is a danger that competitiveness at a territorial level becomes a conceptual chimera. The essential problem is that territorially based actors and agencies seek to position and maintain the utility of their regions and subregions by reference to a set of measures and indicators that are conceptually suspect and often empirically weak. The degree to which regions compete depends on a manifold set of factors. The paper proposes a conceptual framework for regional competitiveness based on combining the competitive advantage of firms and the comparative advantage of a regional economy. The conceptual transmission mechanism to regional competitiveness combines Liebenstein's theory of 'X-inefficiency' and aggl...
