Nature Appropriation and Associations with Population Health in Canada's Largest Cities
(2013-04)Earth is a finite system with a limited supply of resources. As the human population grows, so does the appropriation of Earth's natural capital, thereby exacerbating environmental concerns such as biodiversity loss, ... -
The nature of a gravitationally lensed sub-millimetre arc in MS0451.6-0305: two interacting galaxies at z~2.9?
(2004-08-11)We present a new SCUBA image of the cluster MS0451.6-0305, which exhibits strong, extended sub-mm flux at 850 microns. The most striking feature in the map is an elongated region of bright sub-mm emission, with a flux ... -
The nature of ammonium ion disorder in ammonium tetrafluoroaluminate, NH4AlF4.
(1985)To clarify previous conflicting reports concerning the existence of an order-disorder phase transition in NH4AlF4 at T ?150 K, the heat capacity of this compd. was measured from T = 15 to 305 K, by adiabatic calorimetry. ... -
The nature of the bright submillimeter galaxy population: a radio pre-selected sample with I>25
(2001-2-20)Deep submillimetre surveys have successfully detected distant, star-forming galaxies, enshrouded in vast quantities of dust and which emit most of their energy at far infrared wavelengths. These luminous galaxies are an ... -
Near-IR adaptive optics imaging of nuclear spiral structure in the Seyfert galaxy, NGC3227
(2002-04-04)We present high spatial resolution, near-IR images in J, H, K of the nucleus of NGC3227, obtained with the Adaptive Optics bonnette on CFHT. The ~0.15 arcsec (17pc) resolution allows structures to be probed in the core ... -
Needs and Wants: What Is Social Progress and How Should It Be Measured?

Negative electron-electron drag between narrow quantum Hall channels
(APS through AIP, 1998-03/15)Momentum transfer due to Coulomb interaction between two parallel, two-dimensional, narrow, and spatially separated layers, when a current Idrive is driven through one layer, is studied in the presence of a perpendicular ... -

New algorithms for MODIS sun-induced chlorophyll fluorescence and a comparison with present data products
(2005-02)We discuss important sources of variability in sun-induced chlorophyll fluorescence and examine difficulties in deriving fluorescence data products from satellite imagery, with a focus on the MODerate-resolution Imaging ... -
New insight into the South Tibetan detachment system: Not a single progressive deformation
(2012-03)Low-angle normal faults (LANF), typically regarded as accommodating crustal or lithospheric extension, may also form during lithospheric shortening. The best-studied system of syn-contractional LANFs is the South Tibetan ... -
A new measurement of CO sub(2) eddy flux in the nearshore atmospheric surface layer
(1991)Fluxes of CO sub(2) in the atmospheric surface layer have been measured at a shoreline site by the eddy correlation method using a new CO sub(2) sensor with greater sensitivity than the ones used in earlier studies. In ... -
A NEW METHOD FOR PRIORITIZING CATCHMENTS FOR TERRESTRIAL LIMING IN NOVA SCOTIA
(2015-04)Freshwater acidification is a chronic issue in South Western Nova Scotia (SWNS). Despite reductions in emissions causing acid deposition in SWNS, water quality in the region is not predicted to improve for another 60 years ... -
New production in the warm waters of the Tropical Pacific Ocean
(1994)The average depth-integrated rate of new production in the tropical Pacific Ocean was estimated from a calculation of horizontal and vertical nitrate balance over the region enclosed by the climatological 26 degree C ... -

News from the Galactic suburbia: the chemical composition of the remote globular cluster NGC 2419
(2012-08-01)We present the chemical analysis of 49 giant stars of the globular cluster NGC 2419, using medium resolution spectra collected with the multi-object spectrograph DEIMOS@Keck. Previous analysis of this cluster revealed a ...
