Communications system for zero-g simulation tests in water
System connects seven observers, diver, and spare station, and utilizes public address system with underwater speakers to provide two-way communications between test subject and personnel in control of life support, so that test personnel are warned immediately of malfunction in pressure suit or equipment
TRADITION, CULTURE, AND THE PROBLEM OF INCLUSION IN PHILOSOPHY
Many today agree that philosophy, as an academic discipline, must, for the sake of its very survival, become more inclusive of a wider range of perspectives, coming from a more diverse pool of philosophers. Yet there has been little serious reflection on how our very idea of what philosophy is might be preventing this change from taking place. In this essay I would like to consider the ways in which our ideas about philosophy\u27s relation to tradition, and its relation to other dimensions of human culture, influence efforts to promote greater diversity in the field
Profile of allergy-related articles in the primary academic publication for UK General Practitioners
Background: Concern is often expressed about primary health care professionals’ lack of knowledge about allergies, particularly diagnostic testing and the management of atopic disorders. Limited training opportunities in allergy have been documented in both undergraduate and postgraduate education. The British Journal of General Practice is the leading UK-based Family Practice journal, it has a strong clinical focus. The BJGP was established in 1953. It is a high quality journal and is the world’s 2nd most highly cited journal of general practice and primary care. Methods: Keyword search of bjgp.org. Terms used were ‘allergy’, ‘allergies’, ‘allergic’, ‘rhinitis’, ‘urticaria’, ‘eczema’, ‘angioedema’. All titles and articles from 1953 to 2013 were searched. Full copies of relevant publications were downloaded and variables extracted, including title, year of publication, type of article, clinical focus. As a comparator a similar search was conducted for articles about asthma using the search term ‘asthma’. Results: 41 allergy-related articles were identified in the 60 years since the journal was launched. In the same time period there were 147 articles about asthma. In 31 of the 60 years reviewed there were no articles at all about any allergy-related topic. The focus of the articles published were eczema (6), food allergy (6), rhinoconjunctivitis (5), anaphylaxis (4), urticaria (1). There were no articles on angioedema. Some articles addressed multiple atopic disorders, eg ‘Allergic diseases in the elderly’ (1968), ‘Allergic disorders amongst horticultural, agricultural and forestry workers’ [letter] (1965). Conclusions: Allergy has a low profile in the British Journal of General Practice. This low profile persists despite the increasing prevalence of atopic disorders and major national reports highlighting the need for better care of the allergic patient in primary care. Our exploratory study highlights a missed opportunity to educate and inform General Practitioners about allergy through this widely circulated journal. Further work is needed to understand better why so few articles on allergy are published in the BJGP. If the paucity of publications reflects the number of articles submitted then BSACI members interested in informing and improving allergy management in General Practice should include the BJGP on their list of target journals. Where next: To share these observations with the Editor of the BJGP to understand whether they reflect editorial policy or lack of submissions from clinicians and researchers with expertise in allergy. To work with the BJGP to identify collaborative initiatives to address the serious mismatch between the prevalence of allergy in the clinical consultation and the number of allergy- related articles in the literature for GPs

Kondo insulators in the periodic Anderson model: a local moment approach
The symmetric periodic Anderson model is well known to capture the essential
physics of Kondo insulator materials. Within the framework of dynamical
mean-field theory, we develop a local moment approach to its single-particle
dynamics in the paramagnetic phase. The approach is intrinsically
non-perturbative, encompasses all energy scales and interaction strengths, and
satisfies the low-energy dictates of Fermi liquid theory. It captures in
particular the strong coupling behaviour and exponentially small quasiparticle
scales characteristic of the Kondo lattice regime, as well as simple
perturbative behaviour in weak coupling. Particular emphasis is naturally given
to strong coupling dynamics, where the resultant clean separation of energy
scales enables the scaling behaviour of single-particle spectra to be obtained.Comment: 15 pages, 10 postscript figures, accepted for publication in EPJ B;

Advanced General Aviation Turbine Engine (GATE) study
The small engine technology requirements suitable for general aviation service in the 1987 to 1988 time frame were defined. The market analysis showed potential United States engines sales of 31,500 per year providing that the turbine engine sales price approaches current reciprocating engine prices. An optimum engine design was prepared for four categories of fixed wing aircraft and for rotary wing applications. A common core approach was derived from the optimum engines that maximizes engine commonality over the power spectrum with a projected price competitive with reciprocating piston engines. The advanced technology features reduced engine cost, approximately 50 percent compared with current technology
