Diazotrophic bacteria respond to Saharan dust additions
(2012)Three bioassay experiments were performed to study the effects of nutrient and Saharan dust additions on natural diazotrophic communities in the tropical North Atlantic Ocean. Samples for nucleic acid analysis were collected ... -
Dichloromethane in North Atlantic waters
(2004-09)[1] Dichloromethane is an atmospheric trace gas that has a tropospheric lifetime on the order of 5 months and has major anthropogenic sources. Evidence has been presented for an oceanic source. This paper reports measurements ... -
Dichotomy and pseudogap signature in the Raman response of high-T-c cuprates
(2010-05)No abstract available. -

Dicke-narrowed line shapes in CO-Ar: Measurements, calculations, and a revised interpretation
(2006)No abstract available. -
Differential expression of Hdac2 in male and female mice of differing social status
(Elsevier, 2024-01-01)Mice naturally form social hierarchies and their experiences as subordinate or dominant mice inform future behavioural strategies. To better understand the neural bases of social dominance, we investigated hippocampal gene ... -
Diffusion of Asymmetric Swimmers
(American Physical Society, 2003)Asymmetric swimmers that would move at a constant speed in perfect circles in the absence of fluctuations were studied. Particles moving at a constant speed with either a fixed or a Gaussian distributed magnitude of curvature ... -
Dipole-dipole interactions and the critical resistivity of gadolinium
(1987-06/01)Results are presented for the electrical resistivity of a c-axis single crystal of high-purity gadolinium metal in the immediate vicinity of the Curie temperature. Numerical analysis reveals that the data are not well ... -
Direct observation of remanent magnetic states in epitaxial fcc Co small disks
(2003-04)No abstract available. -
Direct observation of spin configurations and classification of switching processes in mesoscopic ferromagnetic rings
(2003-10)No abstract available. -
Direct observations of diel biological CO2 fixation on the Scotian Shelf, northwestern Atlantic Ocean
(2012)Much of the variability in the surface ocean's carbon cycle can be attributed to the availability of sunlight, triggering surface heat flux and photosynthesis, which in turn regulate the biogeochemical cycling of carbon ... -
Directed Ortho and Remote Metalation of Naphthalene 1,8-Diamide: Complementing SEAr Reactivity for the Synthesis of Substituted Naphthalenes
(American Chemical Society, 2021-03-05) -
The disappearance of Lyα blobs: a GALEX search at z=0.8
(2009-07-13)Lyman alpha blobs - luminous, spatially extended emission-line nebulae, often lacking bright continuum counterparts - are common in dense environments at high redshift. Until recently, atmospheric absorption and filter ... -
Discovery and analysis of three faint dwarf galaxies and a globular cluster in the outer halo of the Andromeda galaxy
(2006-10-01)We present the discovery of three faint dwarf galaxies and a globular cluster in the halo of the Andromeda galaxy (M31), found in our MegaCam survey that spans the southern quadrant of M31, from a projected distance of ~50 ...
