Flight test summary of modified fuel systems

Two different aircraft designs, each with two modified fuel control systems, were evaluated. Each aircraft was evaluated in a given series of defined ground and flight conditions while quantitative and qualitative observations were made. During this program, some ten flights were completed, and a total of about 13 hours of engine run time was accumulated by the two airplanes. The results of these evaluations with emphasis on the operational and safety aspects were analyzed. Ground tests of the engine alone were not able to predict acceptable limiting lean mixture settings for the flight envelopes of the Cessna Models 150 and T337

This paper will present a snapshot of available nonbiomedical stroke ‘services’ used by stroke survivors in two subdistricts of Aceh, Indonesia. Data were collected through interviews, observations, focus groups and vignettes with stroke survivors, their carers, biomedical and nonbiomedical stroke practitioners. Two categories of nonbiomedical practitioners were identified, all of whom discussed and demonstrated an understanding and approach to stroke treatment with multiple layers of influence, predominantly, education, religion and culture. There were a number of areas of overlap between the two categories; some of these influences were also evident in the biomedical practitioners

'It burdens me': The impact of stroke in central Aceh, Indonesia

This is the accepted version of the following article: Norris, M., Allotey, P. and Barrett, G. (2012), ‘It burdens me’: the impact of stroke in central Aceh, Indonesia. Sociology of Health & Illness, 34: 826–840. doi: 10.1111/j.1467-9566.2011.01431.x, which has been published in final form at http://onlinelibrary.wiley.com/doi/10.1111/j.1467-9566.2011.01431.x/abstract.The complex primary and secondary consequences of stroke have often been equated with the concept of biographical disruption, although a number of mediating factors have been identified. However, the research to date is almost exclusively based in western contexts, despite the fact that stroke is increasing most rapidly in low-income and middle-income countries. This research explores the experience of stroke in the rural community of central Aceh, Indonesia. The participants included 11 stroke survivors and 18 carers, with data collected through in-depth interviews and photographic facilitated interviews, supported with participant observation over a nine month period. The participants discussed and illustrated the disruptive result of their stroke, but for most, their ability to maintain religious duties and contribute to their family resulted in a form of biographical continuity. Their strategies and challenges are discussed alongside the implications for care in this context

Copyright @ 2010 Elsevier B.V.Stroke in low and middle income countries is an increasing cause of death and disability, with rates and the estimated burden considerably higher than that of high income countries. Lay explanatory models are believed to be one of the major influences on health seeking behaviour and essential to understand for appropriate education strategies. Despite stroke being a considerable health concern in Indonesia and particularly in Aceh, no studies to date have explored lay stroke models in that context. This paper presents the findings of a qualitative study informed by both hermeneutic phenomenology and ethnography. Based in rural communities in Bener Meriah and Aceh Tengah in Central Aceh, Indonesia, data were gathered through interviews, photographs and observations with 11 persons with stroke (aged 32–69 years) and 18 of their carers. Fieldwork was conducted over nine months between 2007 and 2008. The study examined lay concepts of stroke, described as a condition resulting from a local blockage in blood from multiple causes, many of which are not recognised within the biomedical frame. The blockage is understood to be reversible and therefore the condition curable. This understanding is embedded and sustained in the specific political, cultural, religious and social context. The results illustrate similarities and differences with other cross-cultural studies and suggest areas of future research and points of consideration for stroke education strategies

The first signs of language: Phonological development in British sign language

A total of 1018 signs in one deaf child’s naturalistic interaction with her deaf mother, between the ages 19-24 months were analysed. This study summarises regular modification processes in the phonology of the child sign’s handshape, location, movement and prosody. Firstly changes to signs were explained by the notion of phonological markedness. Secondly, the child managed her production of first signs through two universal processes: structural change and substitution. Constraints unique to the visual modality also caused sign language specific acquisition patterns, namely: more errors for handshape articulation in locations in peripheral vision, a high frequency of whole sign repetitions and feature group rather than one-to-one phoneme substitutions as in spoken language development

Two-dimensional state sum models and spin structures

The state sum models in two dimensions introduced by Fukuma, Hosono and Kawai are generalised by allowing algebraic data from a non-symmetric Frobenius algebra. Without any further data, this leads to a state sum model on the sphere. When the data is augmented with a crossing map, the partition function is defined for any oriented surface with a spin structure. An algebraic condition that is necessary for the state sum model to be sensitive to spin structure is determined. Some examples of state sum models that distinguish topologically-inequivalent spin structures are calculated.Comment: 43 pages.

Asymptotics of Relativistic Spin Networks

The stationary phase technique is used to calculate asymptotic formulae for SO(4) Relativistic Spin Networks. For the tetrahedral spin network this gives the square of the Ponzano-Regge asymptotic formula for the SU(2) 6j symbol. For the 4-simplex (10j-symbol) the asymptotic formula is compared with numerical calculations of the Spin Network evaluation. Finally we discuss the asymptotics of the SO(3,1) 10j-symbol.Comment: 31 pages, latex. v3: minor clarification

Hot corrosion resistance of nickel-chromium-aluminum alloys

The hot corrosion resistance of nickel-chromium-aluminum alloy was examined by cyclically oxidizing sodium sulfate coated specimens in still air at 900, 1000 and 1100 C. The compositions tested were within the ternary region: Ni; Ni-50 at.% Cr; and Ni-50 at.% Al. At each temperature the corrosion data were statistically fitted to a third order regression equation as a function of chromium and aluminum contents. Corrosion isopleths were prepared from these equations. Compositional regions with the best hot corrosion resistance were identified
