    Atlas of the Earth's radiation budget as measured by Nimbus-7: May 1979 to May 1980

    This atlas describes the seasonal changes in the Earth's radiation budget for the 13-month period, May 1979 to May 1980. It helps to illustrate the strong feedback mechanisms by which the Earth's climate interacts with the top-of-the-atmosphere insolation to modify the energy that various regions absorb from the Sun. Cloud type and cloud amount, which are linked to the surface temperature and the regional climate, are key elements in this interaction. Annual, seasonal, and monthly maps of the albedo, outgoing longwave and net radiation, noontime cloud cover, and mean diurnal surface temperatures are presented. Annual and seasonal net cloud forcing maps are also given. All of the quantities were derived from Nimbus-7 satellite measurements except for the temperatures, which were used in the cloud detection algorithm and came originally from the Air Force 3-dimensional nephanalysis dataset. The seasonal changes are described. The interaction of clouds and the radiation budget is briefly discussed

    Ixodes brunneus (Acari: Ixodidae) from Two Bird Hosts: A New Michigan Tick

    Get PDF
    The tick Ixodes brunneus Koch (Acari: Ixodidae) is reported for the first time in Michigan from two bird hosts at two locations in the lower peninsula. All stages of this tick exclusively feed on birds, and are primarily known from the southern U.S., although abundant records occur from northern states. The role of this species as a vector of pathogens is discussed

    The impact of partial smokefree legislation on health inequalities: Evidence from a survey of 1150 pubs in North West England

    BACKGROUND: The UK government claims that between 10 and 30% of pubs and bars will be exempt from proposed legislation to achieve smokefree enclosed public places across England. This arises from the contentious inclusion that pubs and bars that do not prepare and serve food and private members clubs, will be able to allow smoking. We aimed to survey pubs and bars across the North West of England to assess smoking policies and the proportion and variations by deprivation level of venues preparing and serving food. METHODS: We carried out a telephone survey of 1150 pubs and bars in 14 local authorities across the North West of England. The main data items were current smoking policy, food preparation and serving status, and intention to change food serving and smoking status in the event of implementation of the proposed English partial smokefree legislation. RESULTS: 29 pubs and bars (2.5%) were totally smoke-free, 500 (44%) had partial smoking restrictions, and 615 (54%) allowed smoking throughout. Venues situated in the most deprived quintiles (4 and 5) of deprivation were more likely to allow unrestricted smoking (62% vs 33% for venues in quintiles 1 and 2). The proportion of pubs and bars not preparing and serving food on the premises was 44% (95% CI 42 to 46%), and ranged from 21% in pubs and bars in deprivation quintile 1 to 63% in quintile 5. CONCLUSION: The proportion of pubs and bars which do not serve food was far higher than the 10–30% suggested by the UK government. The proportion of pubs allowing unrestricted smoking and of non-food venues was higher in more disadvantaged areas, suggesting that the proposed UK government policy of exempting pubs in England which do not serve food from smokefree legislation will exacerbate inequalities in smoking and health

    Aeroacoustic Experiments with Twin Jets

    While the noise produced by a single jet is azimuthally symmetric, multiple jets produce azimuthally varying far-field noise. The ability of one jet to shield another reduces the noise radiated in the plane of the jets, while often increasing the noise radiated out of the plane containing the jets. The present study investigates the shielding potential of twin jet configurations over subsonic and over-expanded supersonic jet conditions with simulated forward flight. The experiments were conducted with 2 in. throat diameter nozzles at four jet spacings from 2.6d to 5.5d in center-to-center distance, where d is the nozzle throat diameter. The current study found a maximum of 3 dB reduction in overall sound pressure level relative to two incoherent jets in the peak jet noise direction in the plane containing the jets. However, an increase of 3 dB was found perpendicular to the plane containing the jets. In the sideline direction, shielding is observed for all jet spacings in this study
