Barren-ground caribou - a cyclic species: The development of a cycle-stratified harvest model and a cycle analysis of North American barren-ground caribou subpopulations
(2019)
Unlike all other members of the deer family, subpopulations of barren-ground caribou (Rangifer tarandus groenlandicus) exhibit fluctuations in numbers that have been described as cyclic. We created a cyclic individual-based ...
The influence of water table fluctuation on hydrarch succession in two subarctic peatlands in Eastern James Bay, Quebec
(2019)
Northern peatlands contain close to one-third of the world’s soil carbon and changes to their ecology and hydrology play a major role in the fate of these carbon stocks and the direction of their climate feedbacks. Recent ...
Evaluating consumer grade UAVs and their potential applications and implications in Ontario consulting archaeology
(2019)
Archaeological investigation is an inherently destructive process that threatens permanent
data loss if archaeological sites are inadequately recorded. While archaeologists strive to develop
innovative methods to ensure ...
Organic semiconductors containing multi-heteroatom rings
(2018)
Oligomers of thiophene are ubiquitous in molecular materials research. Other ring systems,
especially those lacking at least C2v symmetry are much less common. We investigated
thiophene-thiazole, pyrrole-thiazole, ...
Investigation and optimization of group III-N semiconductor thin-film growths using DC nitrogen plasma
(2019)
The Lakehead University remote plasma-enhanced metalorganic chemical vapour deposition (RPE-MOCVD) reactor utilizes nitrogen plasma to provide the required nitrogen species in group III-N semiconductor material growth. ...
From social media to expert reports: automatically validating and extending complex conceptual models using machine learning approaches
(2019)
Given the importance of developing accurate models of any complex system, the modeling
process often seeks to be comprehensive by including experts and community members.
While many qualitative modeling processes can ...
Catastrophe theory, symmetry breaking and the pseudo Jahn-Teller effect
(2019)
This research focuses on the structural symmetry breaking observed in hypovalent
silicon containing compounds. The structural symmetry breaking was studied from the
perspective of the pseudo Jahn-Teller effect (pJTE). A ...
Movement, resource use, and life history strategies of Black Bay Walley (Sander vitreus)
(2019)
Resource distribution across the landscape can drive movement strategy selection, from sedentary to highly mobile individuals. When paired with other forms of analysis, movement ecology can provide insight into the resource ...
Isolation and characterization of bioconversion microbes and aerobic conversion of crude glycerol to value-added bioproducts
(2018)
Renewable forms of energy are of significant interest in today’s economies. Biofuel is a renewable fuel produced by biological means. Biofuel is very useful because it does not have a finite supply, and it produces fewer ...
Cross-coupling reactions: synthesis and photoactivity of enediynes
(2015-02-02)
The syntheses of a number of photoactive enediynes using the Sonogashira Coupling reaction are described. Alkynes with different characteristics were coupled to 2-bromoiodobenzene to yield the desired drugs. The enediyne’s ...
