GE MOD-1 noise study

Noise studies of the MOD-1 Wind Turbine Generator are summarized, and a simple mathematical noise is presented which is adequate to correlate the sound levels found near the machine. A simple acoustic measure is suggested for use in evaluating far field sound levels. Use of this measure as input to a currently available sound complaint prediction program is discussed. Results of a recent statistical survey relative to the far field variation of this acoustic measure because of atmospheric effects are described

The Path to Gun Control in America Goes through Political Philosophy

This essay argues that gun control in America is a philosophical as well as a policy debate. This explains the depth of acrimony it causes. It also explains why the technocratic public health argument favored by the gun control movement has been so unsuccessful in persuading opponents and motivating supporters. My analysis also yields some positive advice for advocates of gun control: take the political philosophy of the gun rights movement seriously and take up the challenge of showing that a society without guns is a better society, not merely a safer one

Reidentifying hardware after loss of serial number

System traces fabrication and inspection records of special hardware back to the raw material. Reidentification of hardware, after loss of serial numbers, is established by X raying all parts again and comparing the new film with the original, whose numbers were previously recorded on serialized documents

Exile the Rich!

The rich have two defining capabilities: independence from and command over others. These make being wealthy very pleasant indeed, but they are also toxic to democracy. First, I analyse the mechanisms by which the presence of very wealthy individuals undermines the two pillars of liberal democracy, equality of citizenship and legitimate social choice. Second, I make a radical proposal. If we value the preservation of democracy we must limit the amount of wealth any individual can have and still be a citizen of our polity

Palliative care for people with non-malignant lung disease: summary of current evidence and future direction

Background: The physical and psychosocial needs of patients with chronic non-malignant lung disease are comparable to those with lung cancer. This article will focus on chronic obstructive pulmonary disease, interstitial lung disease and cystic fibrosis as examples of life-limiting, non-curable and non-malignant lung diseases. The need for supportive and palliative care: Recent national guidance has demanded that palliative care is inclusive of all patients with life-limiting disease, irrespective of diagnosis, and that specialist palliative care teams are involved in the management of patients on a basis of need rather than prognosis. What is known: Despite medical therapy, most patients with moderate to severe chronic obstructive pulmonary disease, interstitial lung disease and cystic fibrosis experience pain, fatigue and dyspnoea, with the majority not getting relief from dyspnoea towards the end of life. Furthermore, dyspnoea causes social isolation and difficulty performing activities of daily living and impairs quality of life. There is an increasing evidence base for the assessment of supportive and palliative care needs, symptom interventions, prognostication, models of service delivery and implications of these for clinical practice and research in non-malignant lung diseases. What is unknown: Despite advances, much still remains unknown regarding assessment, management and prognostication in individual chronic non-malignant lung diseases. Although different service models are being used in clinical practice, the optimal model(s) of service delivery remain unknown. Implication for future research, policy and practice: We describe key areas for further research, which include the need for large, high-quality trials of pharmacological and non-pharmacological interventions and their combinations as well as evaluation of the efficacy and cost-effectiveness of models of care. As access to palliative care is poor for these patients, the barriers to referral need to be understood and reduced, which along with effective working between palliative care teams, with respiratory services backup, should optimise delivery of care in patients with life-limiting non-malignant lung disease

Transformation without Paternalism

Human development is meant to be transformational in that it aims to improve people's lives by enhancing their capabilities. But who does it target: people as they are or the people they will become? This paper argues that the human development approach relies on an understanding of personal identity as dynamic rather than as static collections of preferences, and that this distinguishes human development from conventional approaches to development. Nevertheless, this dynamic understanding of personal identity is presently poorly conceptualized and this has implications for development practice. We identify a danger of paternalism and propose institutionalizing two procedural principles as side constraints on development policies and projects: the principle of free prior informed consent and the principle of democratic development

Effects of mean flow on duct mode optimum suppression rates

The nature of the solution to the convected acoustic wave equation and associated boundary conditions for rectangular ducts containing uniform mean flow is examined in terms of the complex mapping between the wall admittance and characteristic mode eigenvalues. It is shown that the Cremer optimum suppression criteria must be modified to account for the effects of flow below certain critical values of the nondimensional frequency parameter of duct height divided by sound wavelength. The implications of these results on the design of low frequency suppressors are considered
