Decarboxylative Arylation of Substituted Pyrroles N-protected with 2-(Trimethylsilyl) ethoxymethyl (SEM)
(Canadian Journal of Chemistry, 2018)Palladium-catalyzed decarboxylative arylation is reported using pyrroles N-protected with the 2-(trimethylsilyl) ethoxymethyl (SEM) group and featuring 2-, 3- and 4-substituents about the pyrrolic framework. In contrast ... -
Deciphering Students’Conceptualizations of Campus Sustainability between years of study on Dalhousie’s Studley Campus using the Photovoice Method
(2013-04)Education has been recognized as having a significant influence on environmental consciousness and individual behaviour. However, experts emphasize that traditional education is not enough to transform behaviour. Rather, ... -
Deductions about the Structure of Phase-Iii from Thermodynamic Measurements on Solid Isotopic Methanes
(1979)No abstract available. -
Deep Gemini/GMOS imaging of an extremely isolated globular cluster in the Local Group
(2009-09-08)We report on deep imaging of a remote M31 globular cluster, MGC1, obtained with Gemini/GMOS. Our colour-magnitude diagram for this object extends ~5 magnitudes below the tip of the red giant branch and exhibits features ... -
Deep observations of CO line emission from star-forming galaxies in a cluster candidate at z=1.5
(2012-07-11)We report results from a deep Jansky Very Large Array (JVLA) search for CO 1-0 line emission from galaxies in a candidate galaxy cluster at z~1.55 in the COSMOS field. We target 4 galaxies with optical spectroscopic redshifts ... -
Deep SAURON Spectral-Imaging of the diffuse Lyman-alpha halo LAB1 in SSA22
(2004-06)We have used the SAURON panoramic integral field spectrograph to study the structure of the Ly-alpha emission-line halo, LAB1, surrounding the sub-millimeter galaxy SMM J221726+0013. This emission-line halo was discovered ... -
Deep structure of the ocean-continent transition in the southern Iberia Abyssal Plain from seismic refraction profiles: Ocean Drilling Program (Legs 149 and 173) transect
(1999-04)We present a wide-angle seismic refraction study of an 80x40 km region of the southern Iberia Abyssal Plain, south of Galicia Bank. An intersecting grid of two E-W and four NS wide-angle reflection/refraction profiles is ... -
Deep structure of the ocean-continent transition in the southern Iberia Abyssal Plain from seismic refraction profiles: The IAM-9 transect at 40 degrees 20 ' N
(2000-03)We present a crust and mantle velocity structure for the West Iberia passive continental margin derived from a 320-km-long wide-angle seismic profile acquired in the southern Iberia Abyssal Plain. We observe a 170-km-wide ... -
A Deep WSRT 1.4 GHz Radio Survey of the Spitzer Space Telescope FLSv Region
(2004-09)The First Look Survey (FLS) is the first scientific product to emerge from the Spitzer Space Telescope. A small region of this field (the verification strip) has been imaged very deeply, permitting the detection of ... -
Deep-Sea Coral: Their Use As Climate Change Indicators
(2003-04-15)The need for accurate climate change models is a major issue with the increasing concern of global warming. Recently deep-sea corals have been calibrated for seawater temperatures using isotopic ratios since they record ... -
Deformation and metamorphism in the contact aureole of the S. Mt. Batholith, Bedford area
(1996-04-15)This study documents structures related to Halifax Pluton emplacement, in the Bedford area. Intrusion of the Devonian South Mountain Batholith caused both metamorphism and deformation of the Cambrian-Ordovician Meguma ... -
Demand or Supply for Schooling in Rural India?
(2012-11)Is the poor human capital investment by rural Indian families primarily a supply side or a demand side issue? We examine school attendance and total human capital investment time (time in school plus travel time plus in-home ... -
Demise of the garden of Acadia
(DVL Publishing Inc., Liverpool, Nova Scotia, 1981-07)In the late 1970s, plans were being developed for construction of a tidal power barrage at the mouth of the Annapolis River. Much of the land by the river in that area was dyked and was used by farmers for grazing and ... -
Demonstration of the deposition and modification of dietary fatty acids in pinniped blubber using radiolabelled precursors
(2004-07)Radioisotopes are commonly used to study the in vivo metabolism and deposition of dietary fatty acids in adipose tissue. The application of this approach to pinnipeds is problematic because of their large mass and blubber ... -
Density dependence of critical magnetic fields at the metal-insulator bifurcation in two dimensions
(APS through AIP, 2003-01/15)The density dependence of the critical in-plane magnetic field Bc at the bifurcation of the resistivity of two-dimensional electron systems with low levels of disorder is determined using the spin-polarization dependence ... -

Density Variations in the NW Star Stream of M31
(2011-02-17)The Pan Andromeda Archeological Survey (PAndAS) CFHT Megaprime survey of the M31-M33 system has found a star stream which extends about 120 kpc NW from the center of M31. The great length of the stream, and the likelihood ...
