    Integrated resource planning for urban waste management

    Full text link
    © 2015 by the authors, licensee MDPI, Basel, Switzerland. The waste hierarchy currently dominates waste management planning in Australia. It is effective in helping planners consider options from waste avoidance or "reduction" through to providing infrastructure for landfill or other "disposal". However, it is inadequate for guiding context-specific decisions regarding sustainable waste management and resource recovery, including the ability for stakeholders to compare a range of options on an equal footing whilst considering their various sustainability impacts and trade-offs. This paper outlines the potential use of Integrated Resource Planning (IRP) as a decision-making approach for the urban waste sector, illustrated using an Australian case study. IRP is well established in both the water and energy sectors in Australia and internationally. It has been used in long-term planning enabling decision-makers to consider the potential to reduce resource use through efficiency alongside options for new infrastructure. Its use in the waste sector could address a number of the current limitations experienced by providing a broader context-sensitive, adaptive, and stakeholder focused approach to planning not present in the waste hierarchy and commonly used cost benefit analysis. For both efficiency and new infrastructure options IRP could be useful in assisting governments to make decisions that are consistent with agreed objectives while addressing costs of alternative options and uncertainty regarding their environmental and social impacts. This paper highlights various international waste planning approaches, differences between the sectors where IRP has been used and gives a worked example of how IRP could be applied in the Australian urban waste sector

    Spin Structure of the Proton from Polarized Inclusive Deep-Inelastic Muon-Proton Scattering

    We have measured the spin-dependent structure function g1pg_1^p in inclusive deep-inelastic scattering of polarized muons off polarized protons, in the kinematic range 0.003<x<0.70.003 < x < 0.7 and 1GeV2<Q2<60GeV21 GeV^2 < Q^2 < 60 GeV^2. A next-to-leading order QCD analysis is used to evolve the measured g1p(x,Q2)g_1^p(x,Q^2) to a fixed Q02Q^2_0. The first moment of g1pg_1^p at Q02=10GeV2Q^2_0 = 10 GeV^2 is Γp=0.136±0.013(stat.)±0.009(syst.)±0.005(evol.)\Gamma^p = 0.136\pm 0.013(stat.) \pm 0.009(syst.)\pm 0.005(evol.). This result is below the prediction of the Ellis-Jaffe sum rule by more than two standard deviations. The singlet axial charge a0a_0 is found to be 0.28±0.160.28 \pm 0.16. In the Adler-Bardeen factorization scheme, Δg2\Delta g \simeq 2 is required to bring ΔΣ\Delta \Sigma in agreement with the Quark-Parton Model. A combined analysis of all available proton and deuteron data confirms the Bjorken sum rule.Comment: 33 pages, 22 figures, uses ReVTex and smc.sty. submitted to Physical Review

    Large enhancement of deuteron polarization with frequency modulated microwaves

    Get PDF
    We report a large enhancement of 1.7 in deuteron polarization up to values of 0.6 due to frequency modulation of the polarizing microwaves in a two liters polarized target using the method of dynamic nuclear polarization. This target was used during a deep inelastic polarized muon-deuteron scattering experiment at CERN. Measurements of the electron paramagnetic resonance absorption spectra show that frequency modulation gives rise to additional microwave absorption in the spectral wings. Although these results are not understood theoretically, they may provide a useful testing ground for the deeper understanding of dynamic nuclear polarization.Comment: 10 pages, including the figures coming in uuencoded compressed tar files in poltar.uu, which also brings cernart.sty and crna12.sty files neede

    Substance abuse and intimate partner violence: treatment considerations

    Get PDF
    Given the increased use of marital- and family-based treatments as part of treatment for alcoholism and other drug disorders, providers are increasingly faced with the challenge of addressing intimate partner violence among their patients and their intimate partners. Yet, effective options for clinicians who confront this issue are extremely limited. While the typical response of providers is to refer these cases to some form of batterers' treatment, three fundamental concerns make this strategy problematic: (1) most of the agencies that provide batterers' treatment only accept individuals who are legally mandated to complete their programs; (2) among programs that do accept nonmandated patients, most substance-abusing patients do not accept such referrals or drop out early in the treatment process; and (3) available evidence suggests these programs may not be effective in reducing intimate partner violence. Given these very significant concerns with the current referral approach, coupled with the high incidence of IPV among individuals entering substance abuse treatment, providers need to develop strategies for addressing IPV that can be incorporated and integrated into their base intervention packages

    Human variation databases

    Get PDF
    More than 100 000 human genetic variations have been described in various genes that are associated with a wide variety of diseases. Such data provides invaluable information for both clinical medicine and basic science. A number of locus-specific databases have been developed to exploit this huge amount of data. However, the scope, format and content of these databases differ strongly and as no standard for variation databases has yet been adopted, the way data is presented varies enormously. This review aims to give an overview of current resources for human variation data in public and commercial resources
