    Feasibility analysis of reciprocating magnetic heat pumps

    Get PDF
    The conceptual design selected for detailed system analysis and optimization is the reciprocating gadolinium core in a regenerative fluid column within the bore of a superconducting magnet. The thermodynamic properties of gadolinium are given. A computerized literature search for relevant papers was conducted and is being analyzed. Contact was made with suppliers of superconducting magnets and accessories, magnetic materials, and various types of hardware. A description of the model for the thermal analysis of the core and regenerator fluids is included

    The Indian family on UK reality television: Convivial culture in salient contexts

    Get PDF
    This is the author's accepted manuscript. The final published article is available from the link below, copyright 2012 @ the author.This article demonstrates how The Family (2009), a fly-on-the wall UK reality series about a British Indian family, facilitates both current public service broadcasting requirements and mass audience appeal. From a critical cultural studies perspective, the author examines the journalistic and viewer responses to the series where authenticity, universality, and comedy emerge as major themes. Textual analysis of the racialized screen representations also helps locate the series within the contexts of contested multiculturalism, genre developments in reality television and public service broadcasting. Paul Gilroyā€™s concept of convivial culture is used as a frame in understanding how meanings of the series are produced within a South Asian popular representational space. The author suggests that the social comedy taxonomy is a prerequisite for the making of this particular observational documentary. Further, the popular (comedic) mode of conviviality on which the series depends is both expedient and necessary within the various sociopolitical contexts outlined

    Future proofing the Physiotherapy Profession

    Purpose To explore the role of the physiotherapist as viewed by physiotherapy academics and undergraduate physiotherapy students. The intention is to gain an insight into the future scope of the physiotherapy profession. Methods The study had an exploratory qualitative design, which was undertaken from an interpretive paradigm. A purposive sample was used to recruit participants to two focus groups. One focus group was with academic staff, the second was with 3rd year BSc (Hons) undergraduate physiotherapy students. All participants were recruited from a university in England in 2016. Both focus groups were carried out by the same researcher (SH). Each focus group interview lasted 50-70 minutes and were digitally recorded. An interview schedule was used to guide the interviews. Interview data were transcribed verbatim and analysed using thematic analysis. Results Six participants were recruited to the academic focus group; four were female. Their experience of working in academia ranged from 2 to 23 years. Seven students were recruited to the second focus group; five were female. Three themes were identified and were common to both groups: ā€˜philosophy of practiceā€™, ā€˜changing roleā€™, ā€˜tension between culturesā€™. Conclusion ā€˜Philosophy of practiceā€™: The underpinning philosophy of practice was identified which included transferrable skills, wellbeing, and holistic care. ā€˜Changing roleā€™: A changing role of the physiotherapist was identified. This included a need to incorporate health economics in healthcare provision; and an extended role with a public health focus. Participants perceived the role was being shaped by changes in the Health Service, which was shaped being shaped by the UK governmentā€™s ideology. ā€˜Tension between culturesā€™ were highlighted by both groups. This included: university and clinical practice; the market-place and practice; and current practice and the vision for the future. Implications The physiotherapy profession is ideally placed to lead the way in revolutionising the management of chronic conditions. By understanding how the profession sees itself can ensure the profession is fit for the future. From this the profession can create a vision for the future that may involve a radical change in practice, including the capacity to take on the role of public health promoters

    Distributed leadership, trust and online communities

    This paper analyses the role of distributed leadership and trust in online communities. The team-based informal ethos of online collaboration requires a different kind of leadership from that in formal positional hierarchies. Such leadership may be more flexible and sophisticated, capable of encompassing ambiguity and rapid change. Online leaders need to be partially invisible, delegating power and distributing tasks. Yet, simultaneously, online communities are facilitated by the high visibility and subtle control of expert leaders. This paradox: that leaders need to be both highly visible and invisible as appropriate, was derived from prior research and tested in the analysis of online community discussions using a pattern-matching process. It is argued that both leader visibility and invisibility are important for the facilitation of trusting collaboration via distributed leadership. Advanced leadership responses to complex situations in online communities foster positive group interaction and decision-making, facilitated through active distribution of specific tasks

    Megaloblastic anaemia, diabetes and deafness in a two-year old child

    Get PDF
    Megaloblastic anaemia in childhood usually occurs as a result of dietary folate deficiency or, rarely, congenital disorders of vitamin B12 metabolism. We present a 2-year-old girl with megaloblastic anaemia and insulin-dependent diabetes mellitus, both of which proved responsive to pharmacological doses of thiamine. She was also found to have sensorineural hearing loss. Also known as Rogersā€™ syndrome, thiamine-responsive megaloblastic anaemia is the result of inactivating mutations in a gene encoding a thiamine transporter. A clinical diagnosis is supported by characteristic bone marrow findings and can be confirmed by demonstrating apoptosis in skin fibroblasts cultured in thiamine-depleted medium. Where available, DNA sequencing is definitive. There is rapid reticulocytosis after thiamine administration. We recommend a trial of therapy for megaloblastic anaemia not responding to folate and vitamin B12, especially in a deaf and/or diabetic child

    Galactic conformity and central/satellite quenching, from the satellite profiles of M* galaxies at 0.4 < z < 1.9 in the UKIDSS UDS

    We explore the redshift evolution of a curious correlation between the star formation properties of central galaxies and their satellites (ā€˜galactic conformity') at intermediate to high redshift (0.4 9.7, around central galaxies at the characteristic Schechter function mass, M āˆ¼ M*. We fit the radial profiles of satellite number densities with simple power laws, finding slopes in the range āˆ’1.1 to āˆ’1.4 for mass-selected satellites, and āˆ’1.3 to āˆ’1.6 for passive satellites. We confirm the tendency for passive satellites to be preferentially located around passive central galaxies at 3Ļƒ significance and show that it exists to at least z āˆ¼ 2. Meanwhile, the quenched fraction of satellites around star-forming galaxies is consistent with field galaxies of equal stellar masses. We find no convincing evidence for a redshift-dependent evolution of these trends. One simple interpretation of these results is that only passive central galaxies occupy an environment that is capable of independently shutting off star formation in satellite galaxies. By examining the satellites of higher stellar mass star-forming galaxies (log(M*/MāŠ™) > 11), we conclude that the origin of galactic conformity is unlikely to be exclusively due to the host dark matter halo mass. A halo-mass-independent correlation could be established by either formation bias or a more physical connection between central and satellite star formation histories. For the latter, we argue that a star formation (or active galactic nucleus) related outburst event from the central galaxy could establish a hot halo environment which is then capable of quenching both central and satellite galaxie
