    Prediction of light aircraft interior sound pressure level using the room equation

    The room equation is investigated for predicting interior sound level. The method makes use of an acoustic power balance, by equating net power flow into the cabin volume to power dissipated within the cabin using the room equation. The sound power level transmitted through the panels was calculated by multiplying the measured space averaged transmitted intensity for each panel by its surface area. The sound pressure level was obtained by summing the mean square sound pressures radiated from each panel. The data obtained supported the room equation model in predicting the cabin interior sound pressure level

    Noise path identification using face-to-face and side-by-side microphone arrangements

    In large complex structures, with several major sound transmission paths and high levels of background noise, it can be a complex task to locate and rank the contribution of an individual sound transmission path. The two microphone acoustic intensity techniques are investigated as a tool for path identification. Laboratory tests indicate that, if the intensity transmitted through a particular section of the fuselage is measured in the presence and absence of flanking paths using the face to face and side by side microphone arrangements, then no significant difference exists between the two measured intensities if the face to face microphone arrangement is used. However, if the side by side arrangement is used, then considerable difference exists between the two measured intensities

    Food activities and identity maintenance among community-living older adults: A grounded theory study

    OBJECTIVE. Engaging in food activities and maintaining identity are each important for productive aging. This study explored the role of food activities in identity maintenance among community-living older adults. METHOD. We used a grounded theory approach to analyze data collected in semistructured interviews with 39 predominantly White, British older adults living in West London. RESULTS. Two lifelong food identities "food lover" and "nonfoodie" were maintained in the processes of participation and maintenance and threat and compensation. The process change in meaning and identity explained the development of a third food identity"not bothered" when participants experienced being alone at the table, deteriorating health, and worry about the cost of food. CONCLUSION. Food activities that are a pleasurable and important part of daily life contribute to the maintenance of important identities and mental well-being in older adults.British Geriatrics Society/Dunhill Medical Trust Research Fellowship held by the first autho

    Preparation for cancer care: perceptions of newly qualified health care professionals

    The present paper is derived from a larger survey which examined the perceptions of recently qualified health care professionals’ experience on evidence-based practice, team working and cancer care. This study reports solely on the findings relating to cancer care. The perceptions of recently qualified professionals in relation to their initial educational input on issues such as confidence, anxiety, communication skills and practice in cancer care as well as adequacy of support, professional supervision and use of reflection were gathered using a cross-sectional postal survey design. A total of 50 graduates from each professional category in nursing, occupational therapy, physiotherapy, and social work were sampled yielding a total sample of 200. Eighty-five questionnaires were returned yielding a response rate of 43%. Twenty-eight (33%) respondents stated that they were currently involved in working with people with cancer. These were as follows: 5 nurses, 8 physiotherapists, 9 occupational therapists and 6 social workers. Despite the low response rate, the findings suggest that health care professionals’ educational input and experiences of working with people with cancer were overall positive; for example, in the respondents’ confidence, communication skills, decrease in anxiety and application of knowledge gained in classroom to professional practice. Moreover, most respondents learnt about caring for cancer patients through practice rather than classroom teaching. A high percentage (i.e. 64%;18) across all groups felt supported when caring for people with cancer and reported receiving professional supervision as well as being able to actively reflect on their practice. The implications for education and practice were discussed particularly as there have been few studies conducted in relation to the specific needs and collaborative learning of these health care professional groups

    Light aircraft sound transmission study

    Get PDF
    The revived interest in the design of propeller driven aircraft is based on increasing fuel prices as well as on the need for bigger short haul and commuter aircraft. A major problem encountered with propeller driven aircraft is propeller and exhaust noise that is transmitted through the fuselage sidewall structure. Part of the work which was conducted during the period April 1 to August 31, 1983, on the studies of sound transmission through light aircraft walls is presented

    Determinating the Value of Capital Expenditure Allocation in Indonesia Local Government

    Capital expenditure allocation is aimed to preservation and expansion of local government fixed assets that provide long-term benefit. This paper investigates the factors that affect the capital expenditure allocation in Indonesian local government. Employing a panel pooled data-regression (fixed effect), our results reveal that local productivity, local funding, local budget requirement, and local establishment status are related to the value of capital expenditure. This research found that efficiency of capital expenditure management is related with fiscal dependence

    Correlation effects and the high-frequency spin susceptibility of an electron liquid: Exact limits

    Full text link
    Spin correlations in an interacting electron liquid are studied in the high-frequency limit and in both two and three dimensions. The third-moment sum rule is evaluated and used to derive exact limiting forms (at both long- and short-wavelengths) for the spin-antisymmetric local-field factor, limωG(q,ω)\lim_{\omega \to \infty}G_-({\bf q, \omega}). In two dimensions limωG(q,ω)\lim_{\omega \to \infty}G_-({\bf q, \omega}) is found to diverge as 1/q1/q at long wavelengths, and the spin-antisymmetric exchange-correlation kernel of time-dependent spin density functional theory diverges as 1/q21/q^2 in both two and three dimensions. These signal a failure of the local-density approximation, one that can be redressed by alternative approaches.Comment: 5 page

    Knowing the team around your patient

    There are many different professionals who all contribute to the health and support of patients. Understanding each one’s different specialty is important, so that support workers know who the patient needs to be involved in their care—and when. The Code of Conduct for Healthcare Support Workers and Adult Social Care Workers in England (Skills for Care and Skills for Health, 2013) identifies that working in collaboration with colleagues is an important part of the support worker’s role. Within section three and four it highlights three key areas: support workers must ‘recognise and respect the roles and expertise of your colleagues both in the team and from other agencies and disciplines, and work in partnership with them’; ‘work openly and cooperatively with colleagues, including those from other disciplines and agencies, and treat them with respect’; and ‘communicate effectively and consult with your colleagues as appropriate’. These three keys areas of partnership working, respect and communication will be explored and discussed in this article
