Lake Zooplankton Carbon Sources: The Role Of Terrestrial Inputs And The Effects Of Depth And Taxonomic Composition
(University of Waterloo, 2008-11-28)The relative contribution of allochthonous and autochthonous production in zooplankton nutrition has been of interest since the net heterotrophy of lakes was recognised to be common. I measured the 13C signature of ... -
Lakes of the Peace-Athabasca Delta: Controls on nutrients, chemistry, phytoplankton, epiphyton and deposition of polycyclic aromatic compounds (PACs)
(University of Waterloo, 2012-02-07)Floodplain lakes are strongly regulated by river connectivity because floodwaters exert strong influence on the water balance, the physical, chemical and biological limnological conditions, and the influx of contaminants. ... -
Land Use and Climate Influence Marshes in the Northern Prairie and Parkland Region
(University of Waterloo, 2016-01-21)I evaluated the association between waterbird communities and agricultural activity at 48 non-permanent wetlands, and waterbird response to inter-annual climate variation at 24 non-permanent wetlands. I found six distinct ... -
Landslide damming in Western Sichuan Province, China, with special reference to the 1786 Dadu River and 1933 Diexi events
(University of Waterloo, 2015-08-04)Landslides and landslide damming events can be triggered by various processes, and they can also cause catastrophic damage. With the help of historical documents and Geographic Information System (GIS), historical landslide ... -
Landslide Hazard and Climate Change in the Mountain Glacial Environment of Northwest North America
(University of Waterloo, 2017-09-21)The aim of this thesis was to improve the understanding of the complex interactions between climate change and landslide behavior in the periglacial mountain environment of northwest North America. In particular, this ... -
Landslides triggered by the 1946 Ancash Earthquake (Peru) and geologic controls on the mechanisms of initial rock slope failure
(University of Waterloo, 2009-01-22)The 1946 M7.3 Ancash earthquake triggered a large number of landslides in an epicentral area along the continental divide in the Andes of Peru. Reconnaissance reports by Silgado (1947, 1951), Heim (1949) and Rüegg (1950) ... -
Langmuir-Blodgett Monolayer Studies of Mixed Gemini Surfactant-Phospholipid Monolayers system for Gene Therapy Applications.
(University of Waterloo, 2015-10-23)Gene delivery relies upon the encapsulation of a gene of interest, which is then ideally delivered to target cells. For gene therapy applications, viral vectors are the most efficient vectors currently being studied, ... -
Large-Scale Filaments From Weak Lensing
(University of Waterloo, 2015-10-01)In the context of non-linear structure formation, a web of dark filaments are expected to intersect the high density regions of the universe, where groups and clusters of galaxies will be forming. In this work we have ... -
Large-scale phylogenomic visualization and analysis of functional traits in bacteria
(University of Waterloo, 2019-01-24)The growth of genomic information in public databases has dramatically improved our view of the tree of life and at the same time expanded our knowledge of protein diversity. Through the use of automated annotation pipelines, ... -
Laser Desorption Solid Phase Microextraction
(University of Waterloo, 2006)The use of laser desorption as a sample introduction method for solid phase microextraction (SPME) has been investigated in this research project. Three different types of analytical instruments, mass spectrometry (MS), ... -
Laser-Based Imaging of Novel Charge Density Wave and Superconducting Materials
(University of Waterloo, 2021-06-02)The following thesis presents experimental study of two crystalline materials which show correlated electron phases. The first material 1T-TaS2 is a two-dimensional van-der-Waals material. This family of materials ... -
Laser-cooled Atomic Ensembles in Hollow Optical Fibers
(University of Waterloo, 2021-05-06)This thesis explores hollow-core fibres as a platform for quantum optics experiments with laser-cooled atomic ensembles. The non-diffracting, tightly-confined guided modes of these fibers grant us a ~µm-wide one-dimensional ... -
Laser-initiated Coulomb explosion imaging of small molecules
(University of Waterloo, 2008-09-02)Momentum vectors of fragment ions produced by the Coulomb explosion of CO2z+ (z = 3 - 6) and CS2z+ (z = 3 - 13) in an intense laser field (~50 fs, 1 x 1015 W/cm2) are determined by the triple coincidence imaging technique. ... -
LASS-ICP-MS collection of trace element and 87Sr/86Sr isotope data using a novel uneven distribution of sample material for otolith microchemistry
(University of Waterloo, 2022-01-26)Understanding the behaviour and movement of fish populations is crucial to developing plans to properly manage fisheries, and to predict effects of ongoing environmental change. In northern regions, physically tracking ... -
The Late Proterozoic to Palaeozoic Tectonic Evolution of the Long Range Mountains in Southwestern Newfoundland
(University of Waterloo, 2007-04-04)Ever since the first plate-tectonic model for the Appalachians was proposed, the Laurentian margin has been interpreted as having experienced a collision-related dynamo-thermal event during the Middle Ordovician Taconic ... -
Late-universe signals in the microwave sky: extragalactic dust, electrons, and other baryonic effects
(University of Waterloo, 2021-06-07)This thesis collects much of the work I have done over the last four years as a PhD student. It has two focuses. Part 1 discusses gravitational radiation emitted from two maximally charged black holes in Einstein--Maxwell--dilaton ... -
Laurentide Ice Sheet dynamics evolution in the inner-ice sheet region of northeastern Quebec, Canada
(University of Waterloo, 2020-05-06)The study of past ice sheets, such as the Laurentide Ice Sheet (LIS), which covered most of northern North America during the last glaciation (last ~100-kyr), provides critical knowledge about the long-term behaviour of ... -
Learning about Ontario's Paleozoic Geology with Virtual Reality Google Expedition Tours
(2020-02)How well can you interpret or place into context the different geological features or rock types that are exposed along roadways, rivers, coastlines or construction sites? Here in the Department of Earth and Environmental ... -
A Least-Cost Strategy for Evaluating a Brownfields Redevelopment Project Subject to Indoor Air Exposure Regulations
(University of Waterloo, 2012-08-31)Over the course of the past several decades the benefits of redeveloping brownfields have been widely recognized. Actions have been taken to foster sustainable redevelopment of brownfields by government, policy makers and ... -
