Arctic ecosystems are changing at an alarming rate, with the Arctic Ocean predicted to be summer sea ice free within the next few decades. Beluga whales (Delphinapterus leucas) are the most abundant Arctic odontocete, exhibiting a circumpolar distribution and a strong a...

A new application for reflector antennas is proposed and developed. Using the aperture theory, a phase center on the reflector aperture is determined and shown that, its location is dependent on the field distribution. The proposed concept is, initially, verified by usi...

This study presents an analysis of the observed inter-annual variability and inter-decadal trends in river discharge across northern Canada for 1964–2013. The 42 rivers chosen for this study span a combined gauged area of 5.26 106 km2 and are selected based on data avai...

Ni(II) complexes supported by tridentate N^N–^N diarylamido pincer-type ligands have been demonstrated to act as active catalysts in the carbon–carbon bond forming alkylation of azoles using unactivated alkyl halides. Here, we show that benzannulated phenanthridine-cont...

This dissertation aims to test and evaluate new applications of non-invasive remote sensing and geophysical technologies at three archaeological sites (LdFa-1; LeDx-42; and LbDt-1) located in the interior region of southern Baffin Island, Nunavut. LdFa-1 and LeDx-42 are...

Lake Winnipeg is a valuable freshwater resource known for its fisheries, its plentiful beaches, and its importance to the traditional livelihood of many First Nations and Métis communities. The lake supports both commercial and angling fisheries that add significantly t...

The pure rotational spectra of phenyl isocyanate (PhNCO) and phenyl isothiocyanate (PhNCS) were investigated using Fourier transform microwave (FTMW) spectroscopy in the range from 4 to 26 GHz. For each molecule, rotational transitions due to the parent species and nine...

Mycosphaerella graminicola (anamorph: Septoria tritici), the causal agent of septoria leaf blotch of wheat, has increased in prevalence in the prairie region of Canada in recent years. It is important to know if variation in virulence occurs in the local population as w...

Two new NCS-containing carbon chains of potential astronomical interest, HC4NCS and NC3NCS, were produced through dc electric discharge in a molecular beam and detected by Fourier transform microwave spectroscopy. Rotational transitions from the two species were recorde...

We consider a single-server discrete queueing system in which arrivals occur according to a Markovian arrival process. Service is provided in groups of size no more than M customers. The service times are assumed to follow a discrete phase type distribution, whose repre...
