Microwave-assisted reduction of F-BODIPYs and dipyrrins to generate dipyrromethanes
(Canadian Journal of Chemistry, 2013)The reduction of BODIPYs and dipyrrins to dipyrromethanes, via a reaction involving ethylene glycol and sodium methoxide, is reported. When benzyl alcohol is used in place of ethylene glycol, the addition of 2,4-dinitrop ... -
Mid- to far infrared properties of star-forming galaxies and active galactic nuclei
(2013-2013-)We study the mid- to far-IR properties of a 24um-selected flux-limited sample (S24 > 5mJy) of 154 intermediate redshift (~0.15), infrared luminous galaxies, drawn from the 5MUSES survey. By combining existing mid-IR ... -
A Mid-Infrared Imaging Survey of Submillimeter-Selected Galaxies with the Spitzer Space Telescope
(2009)We present <I>Spitzer</I>-IRAC and MIPS mid-IR observations of a sample of 73 radio-detected submillimeter-selected galaxies (SMGs) with spectroscopic redshifts, the largest such sample published to date. From our data, ... -
Mid-Infrared Spectroscopy of High Redshift Submillimeter Galaxies: First Results
(2007-02-01)We present mid-infrared spectra of 5 submillimeter galaxies at z=0.65-2.38 taken with the Spitzer Space Telescope. Four of these sources, at z<1.5, have strong PAH features and their composite spectrum is well fitted ... -
Mid-Infrared Spectroscopy of Submillimeter Galaxies: Extended Star Formation in Massive High Redshift Galaxies
(2009-03-24)We used the Spitzer Infrared Spectrograph (IRS) to study the mid-IR properties and investigate the energetics of 24 Submillimeter Galaxies (SMGs). This is the largest sample of SMGs observed with Spitzer IRS and covers the ... -
Mid-Pliocene warm-period deposits in the High Arctic yield insight into camel evolution
(2013-03)The mid-Pliocene was a global warm period, preceding the onset of Quaternary glaciations. Here we use cosmogenic nuclide dating to show that a fossiliferous terrestrial deposit that includes subfossil trees and the ... -
MIGMATITES OF THE MUSKOKA DOMAIN, GRENVILLE PROVINCE, ONTARIO
(1998-04-15)The Muskoka Domain, Central Gneiss Belt, Grenville Province, Ontario, is characterized by widespread highly migmatitic orthogneisses. The purpose of this study is to describe a variety of migmatites and associated rocks ... -
"Migration" of blowouts in seagrass beds at Barbados and Carriacou, West Indies, and its ecological and geological implications
(Elsevier Scientific Publishing Company, 1975)Blowouts are grass-free depressions within seagrass beds at Barbados and Carriacou and reported in the literature to be common elsewhere in the Caribbean region. They are typically crescent-shaped in plan view with the ... -
The Mineralogy of the Fifteen Mile Stream Gold District
(1983-04-15)Comparison of two distinct tailings piles from two separate periods of operations, reveals that they are similar in mineralogy and lithology. The proportions in which the minerals and lithic fragments are present, differs ... -
Minor Folds in Coticule Layers and Their Relationship to Regional Fold Evolution, Central Meguma Terrane, Nova Scotia.
(2000-04-15)The highly anisotropic turbidite sequences of the Meguma Group in southern Nova Scotia are folded into upright, noncylindrical, northeast-southwest trending box and chevron folds. Minor folds are well-developed in ... -
Mitochondrial DNA variation, species limits, and rapid evolution of plumage coloration and size in the Savannah Sparrow
(2005-02)We compared sequences from two mitochondrial DNA (mtDNA) genes (ND2, ND3) in Savannah Sparrows (Passerculus sandwichensis; n = 112) sampled from Baja California (five sites), coastal Sonora and the continental range (eight ... -
Mixed evidence for reduced local adaptation in wild salmon resulting from interbreeding with escaped farmed salmon: complexities in hybrid fitness
(2008-08)Interbreeding between artificially-selected and wild organisms can have negative fitness consequences for the latter. In the Northwest Atlantic, farmed Atlantic salmon recurrently escape into the wild and enter rivers where ... -

Mixed Transition Metal Titanate and Vanadate Negative Electrode Materials for Na-Ion Batteries (Preprint)
(IOP Publishing, 2014-11-07)Sodium-ion batteries have the potential to be a low cost, sustainable replacement for lithium-ion batteries in large scale energy storage. The lack of practical negative electrode materials limit the development of Na-ion ... -
Mixed-stock analysis of Atlantic cod near the Gulf of St. Lawrence based on microsatellite DNA
(2000-08)The collapse of various stock complexes of cod (Gadus morhua) in the northwest Atlantic has prompted a clarification of relationships among stock components. Here we examine the genetic composition of >2300 cod collected ... -
Mobilizing Inuit Qaujimajatuqangit in narwhal management through community empowerment: A case study in Naujaat, Nunavut [graduate project].
(2015-11-23)This research examines the relationship between government wildlife management regulations and the use of Inuit Qaujimajatuqangit (IQ) through a case study focusing on narwhal harvesting in the community of Naujaat, Nunavut. ... -
Mobilizing values: Using perceptions of barachois ponds in Cape Breton to advance informed management
(2018-12)Barachois ponds or tidal lagoons are highly dynamic, incredibly productive, yet poorly understood wetlands across Nova Scotia, Canada. Defined by the partial or complete enclosure of a sand or gravel barrier forming a pond, ...
