Multifunctional cellular sandwich structures with optimised core topologies for improved mechanical properties and energy harvesting performance
Get PDFThis paper developed a multifunctional composite sandwich structure with optimised design on topological cores. As the main concern, full composite sandwich structures were manufactured with carbon fibre reinforced polymer (CFRP) facesheets and designed cores. Three-point bending tests have been performed to assess the mechanical performance of designed cellular sandwich structures. To evaluate the energy harvesting performance, the piezoelectric transducer was integrated at the interface between the upper facesheet and core, with both sinusoidal base excitation input and acceleration measured from real cruising aircraft and vehicle. It has been found that the sandwich with conventional honeycomb core has demonstrated the best mechanical performance, assessed under the bending tests. In terms of energy harvesting performance, sandwich with re-entrant honeycomb manifested approximately 20% higher RMS voltage output than sandwiches with conventional honeycomb and chiral structure core, evaluated both numerically and experimentally. The resistance sweep tests further suggested that the power output from sandwich with re-entrant honeycomb core was twice as large as that from sandwiches with conventional honeycomb and chiral structure cores, under optimal external resistance and sinusoidal base excitation

Radiation can cause mutations and thus supply genetic variation; it can also selectively remove individuals that are unable to cope with the physiological stresses associated with radiation exposure, or non-selectively cull swathes of the population, reducing genetic variation. Since the nuclear power plant explosion in 1986, the Chernobyl area has experienced a spatially heterogeneous exposure to varying levels of ionizing radiation. We sampled Daphnia pulex (a freshwater crustacean) from lakes across the Chernobyl area, genotyped them at ten microsatellite loci and also calculated the current radiation dose rates. We then investigated whether the pattern of genetic diversity was positively associated with radiation dose rates, consistent with radiation-mediated supply of de novo mutations, or negatively associated with radiation dose rates, as would be expected with strong radiation-mediated selection. We found that measures of genetic diversity, including expected heterozygosity and mean allelic richness (an unbiased indicator of diversity), were significantly higher in lakes that experienced the highest radiation dose rates. This suggests that mutation outweighs selection as the key evolutionary force in populations exposed to high radiation dose rates. We also found significant but weak population structure, indicative of low genetic drift and clear evidence for isolation-by-distance between populations. This further suggests that gene flow between nearby populations is eroding population structure and that mutational input in high radiation lakes could, ultimately, supply genetic variation to lower radiation sites.NE/L000369/1: Natural Environment Research Council; NE/L011549/1: Natural Environment Research Counci

Introduction: Beyond Inclusion and Exclusion
Get PDFThis chapter appears in a larger collection published by Berghahn Books (https://www.berghahnbooks.com/title/CrouthamelBeyond). CITATION: Crouthamel, J., Geheran, M., Grady, T., & Köhne, J. B. (2018). Introduction. In J. Crouthamel, M. Geheran, T. Grady & J. B. Köhne (Eds.) Beyond inclusion and exclusion: Jewish experiences of the First World War in Central Europe (pp. 1-28). Berghahn.During the First World War, the Jewish population of Central Europe was politically, socially, and experientially diverse, to an extent that resists containment within a simple historical narrative. While antisemitism and Jewish disillusionment have dominated many previous studies of the topic, this collection aims to recapture the multifariousness of Central European Jewish life in the experiences of soldiers and civilians alike during the First World War. Here, scholars from multiple disciplines explore rare sources and employ innovative methods to illuminate four interconnected themes: minorities and the meaning of military service, Jewish-Gentile relations, cultural legacies of the war, and memory politics
International issues in SEND and inclusion: Perspectives across six continents
Get PDFThis is an Accepted Manuscript of a book chapter published by Routledge in [International Issues in SEND and Inclusion: Perspectives Across Six Continents] on [27/09/2022], available online: http://www.routledge.com/International-Issues-in-SEND-and-Inclusion-Perspectives-Across-Six-Continents/Hodkinson-Williams-Brown/p/book/9781032011004This chapter will explore the impact of the cultural frameworks of the society on the Special Educational Needs and Disabilities (SEND) provision in different countries around the world. The influences of cultural dynamics /frameworks on the conceptualization and attitudes towards SEND and provision of services available will be illustrated. The impact of global and local cultures, values, traditions and beliefs affecting the attitudes on the identification and accessing provision for SEND in different countries will be objectively presented. Challenges and tensions around the conflicting policies imposed by the Global North countries on Global South countries and its implications on the provision will be analysed
Silence Is Golden: John William Bobin’s Sylvia Silence and the Emergence of the British Girl Detective in Golden Age Crime Fiction
Get PDFSylvia Silence is a little-known figure today. Created by story-paper writer John William Bobin under the pseudonym Katherine Greenhalgh, she appeared in the Amalgamated Press story paper Schoolgirls’ Weekly in a series of detective narratives from 1922 to 1924 in the early years of the Golden Age of crime fiction. Despite her relative obscurity, however, Sylvia played an important role in the development of the girl detective tradition in juvenile fiction, predating famous American girl detective Nancy Drew by several years. This article explores Sylvia’s emergence from the Victorian and Edwardian tradition of the financially motivated professional or personally motivated amateur female detective and that of Holmesian genius prominent in the Amalgamated Press boys’ story papers into a new detective model for the Golden Age of crime fiction. The article identifies the Golden Age characteristics of Sylvia Silence, particularly those she shares with a much more famous Golden Age female detective, Agatha Christie’s Miss Marple, and draws links between the spinster detective and the girl detective. In particular, it considers why Golden Age crime fiction was a suitable form for the girl detective tradition to develop and thrive within

Intimate partner violence in same-sex relationships: Are we aware of the implications?
Get PDF© 2022 The Author(s)Intimate partner violence (IPV) has been a significant public health problem in same-sex relationships. However, health policies across the globe do not address IPV causing a massive gap in health and economic burden. In the last decade, crucial missing links have been established, and researchers tried to connect the dots of this severe health disparity. This intersectionality has found the impact of race, gender, class, physical ability, and legal framework of IPV in lesbian, gay, and bisexual (LGB) relationships. However, preventive strategies, training programs, and dialogues in the clinical field about IPV are from heteronormative lenses. This particular bias can perpetuate the issue and will remain one of the leading causes of health burden in the LGB population. This article reviews the lacunae in health policies regarding same-sex IPV, highlights its impact on minority mental health, and calls for attention to train health-care professionals regarding the same
The effect of exercise training intensity on VO2max in healthy adults: An overview of systematic reviews and meta-analyses
Get PDFThis study aimed to evaluate systematic reviews and meta-analyses that have examined the effect of exercise training on VO2max in healthy individuals at different intensities. Five databases were searched: EBSCOhost, MEDLINE/PubMed, SPORTDiscus, Web of Science, and Google Scholar. Eligibility criteria for selecting reviews included systematic reviews and meta-analyses of healthy adults that examined the effect of lower intensity training (LIT) and/or high intensity training (HIT) on VO2max. Eleven reviews met the eligibility criteria. All reviews were of moderate-to-very strong methodological quality. The included reviews reported data from 179 primary studies with an average of 23 ± 10 studies per review. All reviews included in this overview showed that exercise training robustly increased VO2max at all intensities. Three meta-analyses that compared LIT versus HIT protocols on VO2max reported small/moderate beneficial effects for HIT over LIT; however, the beneficial effects of HIT on VO2max appear to be moderated by training variables other than intensity (e.g., training impulse, interval length, training volume, and duration) and participants’ baseline characteristics (e.g., age and fitness levels). Overall, evidence from this overview suggests that the apparent differences between LIT and HIT protocols on VO2max were either small, trivial, or inconclusive, with several methodological considerations required to standardise research designs and draw definitive conclusions
