Abstract

The phonon Boltzmann transport equation is used to analyze model problems in one and two spatial dimensions, under transient and steady-state conditions. New, explicit solutions are obtained by using the P1 and P3 approximations, based on expansions in spherical harmonics, and are compared with solutions from the discrete ordinates method. For steady-state energy transfer, it is shown that analytic expressions derived using the P1 and P3 approximations agree quantitatively with the discrete ordinates method, in some cases for large Knudsen numbers, and always for Knudsen numbers less than unity. However, for time-dependent energy transfer, the PN solutions differ qualitatively from converged solutions obtained by the discrete ordinates method. Although they correctly capture the wave-like behavior of energy transfer at short times, the P1 and P3 approximations rely on one or two wave velocities, respectively, yielding abrupt, step-changes in temperature profiles that are absent when the angular dependence of the phonon velocities is captured more completely. It is shown that, with the gray approximation, the P1 approximation is formally equivalent to the so-called “hyperbolic heat equation.” Overall, these results support the use of the PN approximation to find solutions to the phonon Boltzmann transport equation for steady-state conditions. Such solutions can be useful in the design and analysis of devices that involve heat transfer at nanometer length scales, where continuum-scale approaches become inaccurate. [ABSTRACT FROM AUTHOR]

Abstract

Introduction: Out-of-hospital cardiac arrest (OHCA) survival varies greatly between communities. The Utstein template was developed and promulgated to improve the comparability of OHCA outcome reports, but it has undergone limited empiric validation. We sought to assess how much of the variation in OHCA survival between emergency medical services (EMS) across the globe is explained by differences in the Utstein factors. We also assessed how accurately the Utstein factors predict OHCA survival. Methods: We performed a retrospective analysis of patient-level prospectively collected data from 12 OHCA registries from 12 countries for the period 1 Jan 2006 through 31 Dec 2011. We used generalized linear mixed models to examine the variation in survival between EMS agencies (n = 232). Results: Twelve registries contributed 86,759 cases. Patient arrest characteristics, EMS treatment and patient outcomes varied across registries. Overall survival to hospital discharge was 10% (range, 6% to 22%). Overall survival with Cerebral Performance Category of 1 or 2 (available for 8/12 registries) was 8% (range, 2% to 20%). The area-under-the-curve for the Utstein model was 0.85 (Wald CI: 0.85–0.85). The Utstein factors explained 51% of the EMS agency variation in OHCA survival. Conclusions: The Utstein factors explained 51% of the variation in survival to hospital discharge among multiple large geographically separate EMS agencies. This suggests that quality improvement and public health efforts should continue to target modifiable Utstein factors to improve OHCA survival. Further study is required to identify the reasons for the variation that is incompletely understood.

Abstract

Although seafood is considered to be an important part of a healthy and balanced diet, many Australians still do not consume the recommended amounts for good health. Fish is an excellent source of protein, omega-3 fatty acids and other nutrients, and studies have shown that seafood-rich diets can have a lower impact on the environment than diets high in other animal proteins. Concerns about health and sustainability have led to an increased interest in understanding consumers' attitudes toward seafood. This review aims to assess the current knowledge on drivers and barriers to seafood consumption in the Australian context. Systematic search strategies were used to identify relevant peer-reviewed journal articles from three electronic databases (SCOPUS, Web of Science and Science Direct) and grey literature reports from targeted government and industry websites. Accepted studies investigated drivers and/or barriers to seafood consumption in Australia through qualitative, quantitative, or mixed method designs. Initial searches identified 504 publications from which fourteen met the criteria for the review process. The reviewed studies revealed that influences on seafood consumption in Australia are similar to those identified in other developed countries. The leading drivers of seafood consumption are health, taste, and convenience, while the main barriers are price, availability, concerns about quality, and a lack of confidence in selecting and preparing seafood. Some possible intervention strategies targeted toward these factors are explored in the discussion. Future research should focus on designing and implementing specific interventions so that their effectiveness in increasing seafood consumption in Australia can be assessed.

Abstract

We report on a search for the trilepton decay signature from the associated production of supersymmetric gaugino pairs, {tilde {chi}}{sup {plus_minus}}{sub 1}{tilde {chi}}{sub 2}{sup 0}, within the context of minimal supersymmetric models that conserve R parity. This search uses 95 pb{sup {minus}1} of p{bar p} data taken at {radical}(s)=1.8 TeV with the D0 detector. No evidence of a trilepton signature has been found, and a limit on the product of cross section times branching fraction to trileptons is given as a function of {tilde {chi}}{sup {plus_minus}}{sub 1} mass. {copyright} {ital 1998} {ital The American Physical Society}

Abstract

Objectives: Survival after out-of-hospital cardiac arrest (OHCA) varies between communities, due in part to variation in the methods of measurement. The Utstein template was disseminated to standardize comparisons of risk factors, quality of care, and outcomes in patients with OHCA. We sought to assess whether OHCA registries are able to collate common data using the Utstein template. A subsequent study will assess whether the Utstein factors explain differences in survival between emergency medical services (EMS) systems. Study design: Retrospective study. Setting: This retrospective analysis of prospective cohorts included adults treated for OHCA, regardless of the etiology of arrest. Data describing the baseline characteristics of patients, and the process and outcome of their care were grouped by EMS system, de-identified, and then collated. Included were core Utstein variables and timed event data from each participating registry. This study was classified as exempt from human subjects’ research by a research ethics committee. Measurements and main results: Thirteen registries with 265 first-responding EMS agencies in 13 countries contributed data describing 125,840 cases of OHCA. Variation in inclusion criteria, definition, coding, and process of care variables were observed. Contributing registries collected 61.9% of recommended core variables and 42.9% of timed event variables. Among core variables, the proportion of missingness was mean 1.9 ± 2.2%. The proportion of unknown was mean 4.8 ± 6.4%. Among time variables, missingness was mean 9.0 ± 6.3%. Conclusions: International differences in measurement of care after OHCA persist. Greater consistency would facilitate improved resuscitation care and comparison within and between communities.

Abstract

Particulate emboli are an important factor in the development of complications after cardiac surgery. The use of an intra-aortic filter during aortic declamping has proved safe and effective in reducing the incidence of embolic complications. Because aortic cross-clamping is also associated with the risk of embolism, we measured the release of particulate emboli at the time of aortic cross-clamping and at declamping. We deployed intra-aortic filters (Edwards EMBOL-X Slim Protection System) at 2 different times during 15 consecutive cardiac procedures with cardiopulmonary bypass. Filter A was inserted before aortic cross-clamping and left in place for a mean time of 3 minutes, and Filter B was inserted before aortic declamping for a mean of 17 minutes. An independent institution performed histopathologic examination. All filters captured particulate emboli, independent of the patients' degree of proximal aortic atherosclerotic disease. Macroscopy showed that Filter A captured more particles (mean, 70 +/- 2.6) in 7 of 15 patients (46.7%), Filter B captured more particles (mean, 6.7 +/- 2.6) in 5 of 15 patients (33.3%), and the filters captured the same number in 3 of 15 patients (20%). Microscopy showed that both filters captured fibrous atheroma or fibrous cap in 10 of 15 patients. We observed no complications related to the use of the filters. Aortic cross-clamping is associated with a high risk of embolism. We suggest that optimal protection against embolism during cardiac surgery can be achieved by applying intra-aortic filtration not only before aortic declamping but also before aortic cross-clamping.

Abstract

We present the first measurement of the electron angular distribution parameter alpha_2 in W to e nu events produced in proton-antiproton collisions as a function of the W boson transverse momentum. Our analysis is based on data collected using the D0 detector during the 1994--1995 Fermilab Tevatron run. We compare our results with next-to-leading order perturbative QCD, which predicts an angular distribution of (1 +/- alpha_1 cos theta* + alpha_2 cos^2 theta*), where theta* is the polar angle of the electron in the Collins-Soper frame. In the presence of QCD corrections, the parameters alpha_1 and alpha_2 become functions of p_T^W, the W boson transverse momentum. This measurement provides a test of next-to-leading order QCD corrections which are a non-negligible contribution to the W boson mass measurement.

Abstract

Results are presented from analyses of jet data produced in pbarp collisions at sqrt{s} = 630 and 1800 GeV collected with the DO detector during the 1994-95 Fermilab Tevatron Collider run. We discuss details of detector calibration, and jet selection criteria in measurements of various jet production cross sections at sqrt{s} = 630 and 1800 GeV. The inclusive jet cross sections, the dijet mass spectrum, the dijet angular distributions, and the ratio of inclusive jet cross sections at sqrt{s} = 630 and 1800 GeV are compared to next-to-leading-order QCD predictions. The order alpha_s^3 calculations are in good agreement with the data. We also use the data at sqrt{s} = 1800 GeV to rule out models of quark compositeness with a contact interaction scale less than 2.2 TeV at the 95% confidence level., 158 pages, 105 figures, submitted to Phys.

Abstract

We report a new measurement of the pseudorapidity (eta) and transverse-energy (Et) dependence of the inclusive jet production cross section in pbar b collisions at sqrt(s) = 1.8 TeV using 95 pb**-1 of data collected with the DZero detector at the Fermilab Tevatron. The differential cross section d^2sigma/dEt deta is presented up to |eta| = 3, significantly extending previous measurements. The results are in good overall agreement with next-to-leading order predictions from QCD and indicate a preference for certain parton distribution functions.
