We use an iterative generalized least squares map-making algorithm, in conjunction with Monte Carlo techniques, to obtain estimates of the angular power spectrum from cosmic microwave background (CMB) maps. This is achieved by characterizing and removing the instrumental noise contribution in multipole space. This technique produces unbiased estimates and can be applied to an arbitrary experime...
The Mars Global Surveyor (MGS) spacecraft, launched on November 7, 1996, carries an experimental space-to-ground telecommunications link at 32 GHz (Ka-band) along with the primary 8.4-GHz (X-band) downlink used for operational MGS project activities. The signals are simultaneously transmitted from a 1.5-m-diameter parabolic antenna on MGS and received by 34-meter beamwaveguide (BWG) antennas lo...
The fine lunar surface material at the Surveyor 3 landing site has about 3 X 108-dyne/cm 2 cohesion, 35 ø angle of internal friction, 3 X 105-dyne/cm ' static bearing capacity. A small rock withstood a local pressure of 2 X 107 dynes/cm -ø. Soil strength and density increase significantly at depths of a few centimeters. Exposed surface has a considerably higher albedo than the material just bel...
The Planck mission will permit measurements of the polarization of the cosmic microwave background and of polarized foregrounds such as our own Galaxy with an unprecedented combination of accuracy and completeness. This will provide information on cosmological and galactic magnetic fields. The latter can be studied in detail via nearly Faradayrotation free synchrotron and polarized dust emissio...
PURPOSE The purpose of this study was to identify and analyze research into accreditation and accreditation processes. DATA SOURCES A multi-method, systematic review of the accreditation literature was conducted from March to May 2007. The search identified articles researching accreditation. Discussion or commentary pieces were excluded. STUDY SELECTION From the initial identification of o...
[1] Mars Global Surveyor and Mars Odyssey accelerometer measurements of martian upper atmospheric densities reveal the large-scale and small-scale structure of the thermosphere in unprecedented detail. Meridional density gradients, which are seasonally dependent, are greater on the dayside than the nightside, indicating stronger meridional winds on the dayside. Density scale heights do not vary...
AIMS To assess associations between measures of premises-level alcohol-related harm and risk factors for harm. METHODS Thirty-two licensed premises with a history of on-premises violent assault were recruited. An environmental survey of the drinking context of each premises was undertaken. Levels of patron intoxication were assessed using a breathalyser and a visual assessment of customers at...
To assess barriers to implementing standing order protocols (SOP) for vaccinations and influential authorities in making vaccination decisionswith the proportion of black residents, and vaccination coverage in nursing homes. The Centers for Medicare & Medicaid Services and the Centers for Disease Control and Prevention in 2000-2002 surveyed approximately 280 nursing homes in14 states. Data from...
