abstract:
The purpose of this study was to examine youth sport participant’s
achievement goal orientation, Intrinsic motivation and self-efficacy In relation to their
gender and the sport structure they participate in, competitive or recreational.
Situational factors that might influence the climate were also measured. Intrinsic
motivation was assessed with the intrinsic Motivation Inventory (IMI) while goal
orientations were assessed with the Task and Ego Orientation In Sport
Questionnaire (TEOSQ). Self-efficacy was assessed with both quantitative and
qualitative methods. Structure types were checked using the Perceived
Motivational Climate in Sport Questionnaire (PMCSQ) in order to ascertain the
motivational philosophy of the team. Qualitative data was collected from the
coaches of each team regarding their motivational style and coaching certification.
Questionnaires were administered to 161 boys and girls. Thirty of these
participants were Interviewed to gain qualitative data regarding their self-confidence
In soccer. A 2 X 2 (gender X structure) factorial ANOVA revealed a significant
difference for Intrinsic motivation. The competitive league participants had greater
scores of overall Intrinsic motivation, and greater scores In the three IMI subscales
for Interest/enjoyment, perceived competence and effort/importance. Paired sample
t- tests revealed task orientation to be significantly greater than ego orientation In all
participants as well as perceived mastery. The coaches of the competitive structure
were all highly qualified, each having obtained Level 3 certification In the National
Coaching Certification Program. Contradictory to other studies, this study suggests that athletes in a competitive situation can be more intrinsically motivated than
recreational structures. The results suggest that both the recreational and
competitive sport structures were perceived as mastery-based. The highly qualified
coaches may have contributed to the perception of the competitive league being
mastery-based. The present study also found no gender differences in self-efficacy,
which does not support past research.

abstract:
Sand jets and particle clouds in water and viscous fluids have been a frequent subject of intense
research and are pertinent to many environmental, industrial, and engineering processes. Mixing
and dispersion of sand jets and particle clouds in water have been studied to design and optimize
wastewater dredging disposal and marine bed capping. Motion of dispersed particles in viscous
fluids is of great interest in design and operation of oil-sand tailing ponds and modeling magma
flows. The motion of vertical and oblique sand jets passing through an immiscible layer is
controlled by the properties of background fluids, the physical characteristics of sand particles,
and the initial release conditions. Predicting the fate of the instantaneously released sediments in
stratified oil-water system requires knowledge of how various physical factors contribute to the
formation process of sediment clouds.
Laboratory experiments were conducted to study the behaviour of particle clouds passing
through two immiscible fluids (i.e., oil and water), formed by instantaneous release of dry sand
particles from different angles and various heights above the oil layer, and to understand the effects
of controlling parameters on the formation of particle clusters. Different air release heights h,
release angle θ, nozzle diameters do, and sand masses m were tested. Nozzle size and mass of sand
particles were grouped to form a non-dimensional parameter as L/do where L is the length of pipe
filled up with sand particles. Wide ranges of aspect ratios (1≤L/do≤19.6 for vertical and
1.5≤L/do≤24.5 for oblique sand jets) were considered. Air release height was normalized to form
non-dimensional air release height as η.
Effects of the characteristics of sand jets in air such as mass flow rate, sand impact velocity,
and jet diameter on the evolution of oily sand jets were investigated. It was found that the diameter
of sand jet in air linearly correlated with the nozzle diameter. Evolution of oily sand jets with time was investigated using image processing and boundary visualization techniques. Different shapes
of the frontal head and various evolution patterns were observed based on the initial parameters.
The frontal width and velocity of oily sand were measured for different evolution times.
Dimensional analysis was performed, and empirical correlations were introduced to predict the
frontal width and velocity of particle clouds passing through immiscible layer. The average shear
stress in the immiscible layer and in the early stages of evolution was calculated from the
measurements: the normalised shear stress between sand particles and the immiscible layer was
found to linearly increase with the impact momentum. The average drag coefficient of sand jet
front was calculated and results were compared with the classical drag models. The average drag
coefficient of oily sand jets was found to be smaller than the drag coefficient of individual sand
particles in a steady-state condition.

abstract:
Cellulases and glucose isomerases are vital enzymes in converting cellulose into fructose.
Cellulases catalyze cellulose conversion to glucose, while glucose isomerase catalyzes the
reversible isomerization of glucose to fructose. There is a growing interest lately in producing
bio-based chemicals and materials from fructose. Soil bacteria produce these enzymes. The
characterization of bacteria for enzyme saccharification of biomass is essential for fructose
production and reducing the time and cost of current bioconversion processes. From this
perspective, we characterized novel cellulase and glucose isomerase-producing bacteria from soil
samples and optimize their enzyme production. Coculturing and whole-cell immobilization for
glucose isomerase and bacterial resistance to environmental factors were also investigated.
Six bacterial strains, Paenarthrobacter sp. MKAL1, Hymenobacter sp. MKAL2,
Mycobacterium sp. MKAL3, Stenotrophomonas sp. MKAL4, Chryseobacterium sp. MKAL5 and
Bacillus sp. MKAL6 were isolated from mixture soil samples collected at Kingfisher Lake and the
University of Manitoba campus and identified using 16S rRNA gene sequence analysis. Using
plate assay techniques, these strains were selected for cellulase and glucose isomerase production
based on the clearance zone appearance. These strains displayed various morphological and
biochemical characteristics. [...]

abstract:
Physical exercise plays an important role in reducing the physical and
psychological symptoms of those who suffer from Parkinson’s Disease (PD).
One form of exercise, water exercise, is a relatively untested means in the
treatment of patients suffering from PD. Very few studies have tested the effects
of such a program for PD patients. In this pilot study, four patients with PD aged
71-89 years of age followed a six week exercise program in water, three days
weekly for a duration from 20 minutes up to one hour in an attempt to improve
physical and psychological functions. Testing was done prior to and after the
program. The study showed that patients improved on their physical strength,
endurance and balance, however tests of perceived self confidence showed no
difference between the beginning and end of the study. The results suggest that
water exercise is a beneficial medium for PD patients to exercise in and is useful
in maintaining and/or improving on strength, endurance and balance. Further
research with a randomized controlled trial and a larger sample size is needed to
verify the beneficial effects of water exercises for sufferers of PD.

Lichen bioactivities

abstract: The search for novel, pharmacologically significant compounds is a perpetual quest on which biologists, chemists, and bioinformaticians incessantly embark. The sources of these compounds are often of natural origin, making bioprospecting an enticing area of research. One such source of these natural compounds are lichens, which can produce a plethora of bioactive compounds. Historically, lichens have been held as medicine in traditional healing, while in modern times, research has begun to lend validity to these claims. The aim of this thesis was to extract, separate, identify, and evaluate the anti-cancer and antibiotic activity of numerous bioactive compounds and extracts from North American lichens. Antibacterial efficacy was analyzed via resazurin reduction assay, while anticancer ability was evaluated using the MTT assay and propidium iodide flow cytometry. The lichens studied include Xanthoparmelia mexicana, Lobothallia alphoplaca, and Umbilicaria muhlenbergii. Results from the crude acetone maceration extracts of the lichen showed promise of antibacterial activity against gram-positive bacteria (Xanthoparmelia mexicana, MIC of 41.9 μg mL-1 and 20.9 μg mL-1 against E. faecalis and S. aureus, respectively) while other crude extracts showed promising anticancer activity (Lobothallia alphoplaca, IC50 of 87.0 μg mL-1 against MCF-7 cells, MTT assay). Furthermore, Umbilicaria muhlenbergii showed bioactive prowess against both gram-positive bacteria and cancerous cells, with an MIC of 22.5 μg mL-1 against S. aureus and an IC50 of 13.3 μg mL-1 against MCF-7 cells. Due to it’s marked bioactivity, Umbilicaria muhlenbergii crude extract was further separated with silica gel 60 column chromatography, where multiple fractions were found to be bioactive against select bacteria and MCF-7 cells. Two of these silica gel 60 fractions were then further separated with Sephadex LH-20, yielding multiple fractions which exhibited bioactivity against select bacteria, in addition to anti-cancer abilities and cell-cycle arrest abilities. Further studies will need to be undertaken to fully identify compounds from and evaluate the bioactivity of the lichen extracts investigated.

abstract:
The olfactory system is essential for a fish to be successful in an ecological context, and has been demonstrated to be sensitive to a variety of toxicants. The current biotic ligand model (BLM) for copper is an acute-toxicity model based on the gill that is used to predict site-specific safe copper concentrations. Recently, work has been done to develop a BLM based on a more sensitive tissue, namely the olfactory epithelium. The work presented in this dissertation determines that a number of the assumptions of the current acute-toxicity gill-based BLM do not hold for the olfactory epithelium. Two techniques were employed for the work contained within this dissertation, a neurophysiological measure of olfactory acuity, electro-olfactography (EOG), and measurement of behavioural responses. For all experiments, fathead minnows (Pimephales promelas) and yellow perch (Perca flavescens) were used as these species are ubiquitous in waterways across Canada. Fathead minnows were exposed to low, ecologically-relevant concentrations of copper for varying exposure durations in hard and soft water. While it was determined that there was a significant of inhibition of olfactory function as measured by EOG, there was recovery, at least partially, of EOG function with increased exposure duration. It was also determined that not only does calcium have no protective effect against copper-induced olfactory dysfunction at the olfactory epithelium as it does at the gill, but calcium induces its own response. The response to calcium in fathead minnows was further investigated. Fathead minnows had a strong olfactory-dependent avoidance response to calcium. The reduction in EOG response caused by calcium was demonstrated to be due to cross-adaptation with the odourant used, namely L-arginine. Different olfactory sensory neuron (OSN) classes within the olfactory epithelium respond specifically to different odourants. Exposures of fathead minnows or yellow perch to copper demonstrated that there was a specific impairment of ciliated OSNs, while exposure to nickel resulted in impairment of
microvillous OSNs. Behavioural work with fathead minnows using an anti-predator cue demonstrated that copper impairs the response to an anti-predator cue, while nickel does not. These observations demonstrate that ciliated cells are responsible for mediating response to anti-predator cue, which is the first time response to a specific chemosensory cue has been directly connected with a specific OSN class. The work presented in this dissertation represents a significant advancement in our understanding in how copper impairs the olfactory system of fish, which will aid in the construction of models and regulations to protect fish populations.

abstract: How may an arts practice be considered a research methodology? This thesis examines two arts integrating methodologies, arts based research and a/r/tography, to uncover their epistemological constructs and philosophical positions. The inquiry begins with inquiry, a re/cursive/search for an appropriate methodology to allow both critical and creative windows from which to gaze. Using a  unique, hybridized design involving educational criticism (Eisner), the creative process of poetic inquiry (Hawkins, Prendergast), and heuristic inquiry (Moustakas), this thesis demonstrates that both arts based research and a/r/tography resist positivism – but for different reasons and to different effect. Arts based research is a methodology that looks structurally and constructively at the nondiscursive symbolic system of art, and offers tools for understanding the uncertain meaning in art. A/r/tography is a methodology that sees knowledge as rupture: it refuses to engage with positivist structures, actively disrupts them, and finds knowledge through disruption. Both methodologies prompt as many questions as answers in regards to how art is a way of knowing.

subject: Safe sex in AIDS prevention Psychological aspects

abstract:
The information-motivation-behavioral skills (IMB) model of
AIDS-preventive behaviour (Fisher & Fisher, 1992) was used
to examine the relationships among AIDS-preventive
knowledge, motivation, self-efficacy, and behaviour. Gender
was examined to determine whether it predicted self-efficacy
and behaviour. Sociosexual orientation was examined to
determine whether it predicted self-efficacy and behaviour
beyond gender. Having greater knowledge was found to predict
higher self-efficacy whereas higher motivation predicted
more AIDS-preventive behaviours. Gender predicted both selfefficacy
and behaviour. Females obtained higher selfefficacy
and behaviour scores than males. Females also
tended to have more restricted sociosexual orientations than
males. Sociosexual orientation predicted behaviour but not
self-efficacy. Higher AIDS-preventive behaviour scores were
predicted by a more restricted sociosexual orientation.

abstract:
Water is one of the primary resources to sustain human life. The quality of good
water and air are important factors to protect human health and the environment. The
impact of container material on stored water quality is investigated in this study. The
objective of this research is to compare the performance of a polyethylene (plastic)
container to that of a bioplastic container over a period of 32 days. Water quality
parameters analyzed were temperature, acidity (pH), turbidity and dissolved oxygen
(DO). Both container types met the water quality requirements for safe drinking water,
but the bioplastic container performed better over polyethylene. Bioplastic materials
have the added sustainable benefit of being made from natural components that result in
less harm to the environment both in production and degradability.


title: Matrix : from representation to simulation and beyond

contributor:
Genosko, Gary
Ivison, Doug

abstract:
The issue of representation remains a key area of exploration for critical theory and
philosophy during the 20th century. Broadly speaking, the project, in part, of post-structural
and Postmodern theorists has been to explore representation and the way in
which our altered stance towards it has reconfigured the scope of our understanding of
the social, political, economic and artistic worlds. Specifically, Jean Baudrillard and
Gilles Deleuze most radically investigate what exactly such a challenge to our
understanding of the world means through their concepts of simulation, which depart
from its source in Plato’s theory of forms. This thesis employs the Wachowskis’s
blockbuster films The Matrix trilogy as examples through which to apply Baudrillard’s
and Deleuze’s concepts of simulation so as to probe the limits of the meaning of
representation as it applies to contemporary film and critical theory.
This thesis looks at both the genealogy as well as the contemporary uses of
simulation in the works of Baudrillard and Deleuze, while also expanding this analysis to
include other relevant concepts in both theorists’ vocabulary such as symbolic exchange,
territoriality, and becoming. The works of Baudrillard and Deleuze are contrasted at
various points throughout the thesis in their application to The Matrix trilogy so as to
show not only the particularly relevant nuances of the concepts of both theorists, but also
in order to expand the analysis of the Wachowskis’s films so as to interrogate the value of
each theory when put into practice in a contemporary, cultural film. The character
analysis of The Matrix trilogy specifically focuses on Neo and Agent Smith, both of
whom stand in a problematic relationship to the mechanics of representation; the former’s
identity is unstable as it operates within and from without the matrix program, while the
latter’s identity is, at best, indeterminate as it is self-propelled and chaotically multiplies through viral replication. Neo is analyzed with regards to the key references made by
The Matrix trilogy to Baudrillard’s work in such scenes as the one in which Simulacra
and Simulation appears as a prop in Neo’s apartment, as well as his discussion with
Morpheus that makes direct reference to the Borges fable. Baudrillard’s own dismissal of
the film as accurately responding to his theories is also considered. This analysis is
developed further by contrasting Baudrillard’s and Deleuze’s versions of simulation
through Brian Massumi’s characterization of the latter’s privileged space of resistance.
Here, Baudrillard’s orders of simulation and symbolic exchange are juxtaposed with
Deleuze’s simulation and becoming in an exploration of the figure of Agent Smith and
the extent to which either theory can provide resistance to hegemonic systems in post-representational
contexts.

abstract:
The next-generation of wireless networks is required to support a myriad of new demands,
including higher data rate, lower latency, greater system capacity, massive connectivity, as
well as increased power efficiency. Among various technologies, spatial modulation (SM)
and non-orthogonal multiple access (NOMA) have been proposed as promising technologies that can achieve high spectral and energy efficiency. Furthermore, utilizing cognitive
radio (CR) systems and millimeter-wave (mmWave) bandwidth have been offered as novel
solutions to the spectrum scarcity problem. Interestingly, SM, NOMA, CR, and mmWave
can be integrated together to fulfill some of the upcoming generation’s wireless network requirements. Being able to design of reliable transceivers that can meet these requirements
is of great interest in the electronics and communications communities. Direct-conversion
transceivers are built with the objective of directly up-converting the baseband signal to
radio frequency (RF) at the transmitter and directly down-converting the received signal
at the receiver. This characteristic makes it a promising transceiver architecture due to its
small size, low cost, and more efficient energy consumption. While these advantages are very
favourable, the direct-conversion transceivers are susceptible to some hardware impairments
(HWIs) which limits the communication system performance. In-phase/quadrature-phase
(I/Q) imbalance represents one of the most critical direct-conversion transceivers HWIs.
This thesis studies the effects of I/Q imbalance and improper Gaussian noise (IGN) on
the performance of modern communication system techniques. Different receiver designs
are proposed to optimize the system bit error rate (BER) when the transmitter and receiver
operate under the effects of the I/Q imbalance in the presence of IGN at the receiver. More
specifically, underlay CR secondary, quadrature spatial modulation (QSM), space shift
keying (SSK), and two user NOMA receivers are studied and analyzed. Closed forms of
average pairwise error probability (APEP) and upper bound of the average BER formulas
are derived for all receivers. These formulas are derived considering the Beckmann fading
channel model, where most of the well-known fading channel models can be considered as
special cases. The proposed designs show solid performance against I/Q imbalance effects.
In fact, these effects can be totally mitigated if they exist at the receiver and can be significantly reduced if they are at the transmitter. All analytical results are verified by
computer simulations.
This thesis affords important results for the building of future wireless receivers. In
particular, it can be used for developing digital signal processing (DSP) chips to mitigate
the I/Q effects and properly treat the IGN at the receiver. Conclusively, this thesis and
the related publications can be extended to design receivers that can mitigate the effects of
HWIs on new promising technology. For example, the impact of HWIs on cell-free massive
multiple-input multiple-output (MIMO) and intelligent reflecting surface (IRS) is still an
active issue.

abstract: The anatomy of an eating episode is influenced by various psychological, biological, and behavioural factors. The research has supported the existence of a biological correlate of satiety called salivary a-amylase (Harthoorn, L.F., 2008). The present study replicated and extended this finding to examine potential differences in levels of salivary a-amylase in unrestrained eaters compared to restrained eaters. According to the boundary model for the regulation of eating, restrained individuals have different experiences with respect to satiety compared to unrestrained individuals (Herman, C.P., & Polivy, J., 1984).

subject: Electromagnetic damper

subject: Simultaneous vibration control

subject: Energy harvesting

abstract:
The dynamic vibration absorber, or tuned mass damper, has been one of the most commonly used passive vibration control devices over the past hundred years. With an optimally designed vibration absorber, significant vibration suppression can be achieved to maintain structure health and integrity. On the other hand, researchers are seeking effective energy harvesting techniques to harvest energy from ambient vibration for purposes such as powering sensor networks and microsystems. This has brought light to the investigation of simultaneous vibration suppression and energy harvesting. This research is thus motivated to develop an apparatus with a non-traditional vibration absorber in order to achieve vibration control and energy harvesting simultaneously.
For a traditional vibration absorber installed to a single-degree-of-freedom primary system, the absorber damper is connected between the primary mass and the absorber mass. The tuning strategies of such a traditional absorber have been thoroughly studied and energy harvesting techniques have also been applied to the combined system. This research studies a non-traditional vibration absorber whose absorber damper is connected directly between the absorber mass and the base. An apparatus is developed in which an electromagnetic damper used as both the absorber damper and energy harvester is placed between the absorber mass and the base. The principle of the electromagnetic damping is discussed, and the optimum parameters of the non-traditional vibration absorber are studied with respect to different performance indexes under various types of excitation. Analytical derivation, numerical simulation and experiment results are presented in the investigation of each of the tuning strategies. The study has indicated that despite the inevitable trade-off between vibration suppression and energy harvesting, the proposed apparatus is capable of achieving the dual goal with a satisfying performance.

subject:

Gunflint and equivalent formations

abstract:
The 1.878 Ga Gunflint and equivalent iron formations of the Animikie Basin were deposited during the period after the rise in atmospheric oxygen during the Great Oxidation Event, which began at approximately 2.4 Ga. The atmospheric composition, and especially oxygen content, during this period after the rise in atmospheric oxygen, is not well known. The Gunflint and correlative formations, having been deposited in a shallow-marine setting, might provide information on oxygen levels present in the atmosphere-ocean system at this time. This is further made possible as the rocks that make up these formations are excellent records of transgression and regression of the sea. This record is reflected in up-section changes in lithology of the rocks that make up these formations. Further, the strata show evidence of exposure indicative of maximum regression. This exposure would have allowed the sediments and rocks to interact chemically with the atmosphere and meteoric water at the time.
Stromatolites developed in the near-shore deposits and the rocks upon which the stromatolites grew show evidence of exposure during the repeated relative sea level low stands. These rocks have an alteration pattern that depends on their lithology. The rocks that comprise the Archean crystalline basement below the Gunflint show an intense alteration pattern that includes the formation of large corestones as well as increases in Fe and Mn content. Their geochemistry is largely the result of alteration by basin derived fluids. The exposure surfaces in the grainstones that make up the Gunflint and equivalent formations exhibit cementation and brecciation of the grainstones directly beneath the stromatolites.
Geochemical analysis performed on these rocks targeted the concentration of redox sensitive oxides and elements; Fe2O3, MnO, V, Cr, Mo and U. Also considered were the Ce and Eu anomalies present. These oxides and elements react differently in oxidizing vs. reducing fluids. Subsequently, this analysis showed a shift in the Ce anomaly throughout the stratigraphy. The change from negative Ce anomalies in the basal samples to the positive Ce anomalies in the middle and upper lowstand layers indicate a shifting redox boundary, where the lowest stromatolite layers had produced enough oxygen to balance the flux of Fe2+- rich seawater in a position away from them, whereas the middle and upper stromatolite areas had redox boundary at the surface of the stromatolite themselves. Enrichment in Cr and V, as well as depleted Eu anomalies in strata associated with lowstands, points to the mixing of oxic freshwater, probably a combination of surface runoff from the craton and diffusion of groundwaters, and the anoxic seawaters filling the basin.

subject: Thermal sensors

abstract:
There are many contemporary contexts in which a small, low-power-consumption temperature sensor is very valuable. Power, area, speed and temperature range factors are important constraints in modern VLSI design. As transistor dimensions decrease, it is possible to lower the operating voltage of circuits, and dynamic voltage scaling (DVS) has been successfully implemented in several commercial applications to reduce power consumption. Power density is increasing, and the resultant temperature issues are being addressed by DVS, considered an
efficient dynamic thermal management (DTM) technique. DVS/DTM automation techniques require thermal sensors that operate over a range of supply voltages. Therefore, temperature sensor designs such as this one are needed to address these engineering challenges.
In this thesis, a DVS-capable ultra-low-power sub threshold temperature sensor in 180 nm CMOS technology is proposed. The design is composed of a proportional-to-absolute-temperature (PTAT) current generator modified for insensitivity to power supply variation. The design is monolithic; the included reference current generator is a peaking source whose input is fed back from the output of the sensor. The design procedure includes empirical parameter extraction from BSIM simulations to yield a transistor model viable for design calculations, and adjustments to biasing and transistor dimensions to minimize power consumption and maintain adequate voltage supply independence and linearity. The design utilizes the exponential characteristics of sub threshold CMOS transistors to construct an output current that is a firstorder Taylor approximation proportional to the thermal voltage. This is the first time such a design scheme is presented.

abstract:
Wheeled mobile robots are becoming increasingly important in industry as means of
transportation, inspection, and operation because of their efficiency and flexibility.
The design of efficient algorithms for autonomous or quasi-autonomous mobile robots
navigation in dynamic environments is a challenging problem that has been the focus
of many researchers dining the past few decades.
Computer vision, maybe, is not the most successful sensing modality used in mobile
robotics until now (sonar and infra-red sensors for example being preferred), but it is
the sensor which is able to give the information ’’what” and ’’where” most completely
for the objects a robot is likely to encounter.
In this thesis, we deal with using vision system to navigate the mobile robot to track
a reference trajectory and using a sensor-based obstacle avoidance method to pass by
the objects located on the trajectory. A tracking control algorithm is also described
in this thesis. Finally, The experimental results are presented to verify the tracking
and control algorithms.

abstract:
The Macgillivray site (DbJm-3) is located on an island in Whitefish Lake, approximately 50 km
southwest of Thunder Bay, Ontario in the central Canadian Boreal Forest ecozone. Indigenous people
have lived in this area for a long time with the earliest sites occupied during the First Ancestor period,
but occupation intensified during the Woodland period. Kenneth Dawson first excavated at this site in
1966, and Lakehead University has more recently investigated other parts of the site in 2016 and 2017.
Although Dawson highlighted the Laurel composite cultural affiliation, recent analysis has also identified
Brainerd ware, Blackduck complex, Psinomani culture/Sandy Lake ware, and Selkirk composite
affiliations.
This thesis examines the macrobotanical and zooarchaeological evidence from the Macgillivray
site to assist with reconstructing the diets of its precontact Indigenous Woodland period occupants.
There is a lack of direct evidence for the consumption of wild resources on sites in Northwestern
Ontario. Due to this, organic resources consumed and exploited by the Woodland period people have
been inferred through other means such as modern environmental data, archaeological settlement
patterns, ethnographic analogies, tool kits and other circumstantial evidence. More recently, carbonized
food residue has provided evidence for the consumption of cultivated plant remains and wild rice. This
suggested that the diets of the Woodland period people in Northwestern Ontario are more complex
than previously assumed. Further information gathered from fauna and macrobotanical remains during
this study aided in contextualizing the cultivated plant component of the diet inferred from microfossils.

A pre-test, intervention, post-test model was used. Both the tests and the lessons were developed to address six areas of difficulty as identified in the literature as causing problems for students in this measurement topic: measuring areas of various objects, static perspective of area, dynamic perspective of area, spatial structuring and covering, estimation, and the area of an amorphous figure.  There were four major findings: students had a positive affective response to the reform method of teaching, students adopted a wider range of strategies to solve problems, students were able to communicate and justify their ideas to others and, students developed a conceptual understanding of topics that the research literature stated are normally only superficially understood by Grade 7 students.--abstract.

Nematode-destroying fungi
Wood-decaying fungi

abstract: Fungi are ubiquitous in forest ecosystems and are, collectively, a major force in driving nutrient and organic matter availability and cycling. Some saprotrophic and mycorrhizal fungi are characterized by a perennial vegetative body, delayed sexual reproduction, and a relatively long lifespan. Such fungi are exposed to a barrage of antagonistic forces throughout their existence, one notable stress being invertebrate grazing. It is suggested that fungi with perennial mycelia must have developed means to deter grazing of their hyphal networks by pervasive mycophagist invertebrates.Controlled inoculation studies with a mycophagous nematode, Aphelenchoides sp., and isolates representing 78 fungal species were conducted to investigate the presence of possible antifeedants. These in vitro pairings resulted in the discovery of two novel antifeedant mechanisms in three species of fungi. In the presence of the saprotrophic fungi Sphaerobolus stellatus and S. iowensis, the anterior portion of nematodes became encapsulated in a material of unknown composition. This encapsulation phenomenon effectively prevented further hyphal grazing by obstructing stylet extension, which resulted in the eventual death of the nematode. Nematodes that died as a result of the encapsulation were never colonized or consumed by the fungus. It is hypothesized that the encapsulating material originates from modified hyphal cells, referred to as gloeocystidia, and is liberated when the cells are punctured by the nematode stylet. The wood-decaying fungus Climacodon septentrionalis was found to produce tall, stalked secretory cells in abundance on the aerial mycelia of the colony. Nematodes were enveloped and immobilized by droplets produced at the apices of the secretory cells. Immobilized nematodes were rarely colonized by the fungus and dead individuals persisted for weeks. A media study was employed to investigate the effect of nutrient concentration on the in vitro production of secretory cells. The discovery of novel antifeedants which mitigate damage caused to the mycelial network by grazing invertebrates offers a stimulus for further investigation into the interactions between fungi and their co-inhabiting microfauna. Keywords: Antifeedant, defence mechanism, fungivory, grazing responses, mycology, mycophagy, perennial mycelium.


title: Lithostratigraphy and provenance of the Neoarchean McKellar Harbour Sequence, Superior Province, Ontario, Canada

subject: Geology Ontario, Northwestern

subject: Geology, Structural Ontario, Northwestern

abstract:
The McKellar Harbour Sequence is located on the shore of Lake Superior approximately
40 km west of the town of Marathon, Ontario. The Sequence was examined in detail
through stratigraphic and geochemical investigations in order to determine the depositional
environment and provenance of these rocks.
Four subsequences were identified in the McKellar Harbour Sequence, consistent with the
facies associated with a distal submarine ramp environment. The Sequence shows
thickening and coarsening upward trends, indicative of progradation of the ramp onto the
basin floor. This indicates that the rocks of the McKellar Harbour Sequence are the distal
equivalents of the proximal submarine ramp facies identified in the Beardmore-Geraldton
and Quetico terranes to the north of the study area. Sedimentary strata from other potential
source regions did not exhibit the characteristic features of a submarine ramp, and were
likely deposited through different processes. Insufficient data were collected to determine
the depositional environment for these units.
Geochemical analyses indicate that the rocks of the McKellar Harbour Sequence have
immobile element chemistry that is very similar to that of the Beardmore-Geraldton and
Quetico terranes, and that a continuum of deposition from north to south is present.
Sediments generated in the Beardmore-Geraldton terrane were transported to small basins
associated with the Schreiber-Hemlo volcanic island system by a submarine ramp.

abstract: The purpose of this study is two-fold. The first is to develop a measurement instrument of patient perceptions of privacy in the healthcare sector. Privacy is critical in health care since it affects patient perceptions of the various aspects of their experience. The second objective of this study is to empirically investigate how privacy affects patients' trust in their health care provider, which in turn influences their commitment, word-of-mouth, and future intentions to use the service. Based on a comprehensive literature review, it was proposed that privacy is a multidimensional construct which consists of three theoretically independent dimensions: informational, physical and psychological privacy. A survey instrument was developed and subjected to extensive face validity assessment.


title: Fighting an uphill battle : a history of public health reform in Fort William, 1892-1919

subject: Public health (Ontario Fort William History)

subject: Public health (Thunder Bay History)

abstract:
This thesis examines the public health problems faced by the city of Fort William
from the 1890s to 1919. It deals specifically with the views of local health officials and
the efforts that they undertook to remedy existing public health concerns. It also includes
an investigation into the extent to which the urban community cooperated with, and
facilitated, local public health efforts. Was there resistance to local public health
initiatives? Did the medical community always work in cooperation with city health
authorities? Was the City Council always in favor of public health efforts?
Each chapter begins with an examination of public health problems in Britain and
North America as a whole, in order to ascertain whether or not Fort William’s experience
in the area of public health was typical. Each chapter demonstrates that Fort William’s
public health concerns were similar to those experienced throughout Britain and North
America. With urbanization came numerous health problems, none of which was alien to
Fort William. The unsanitary condition of urban centres was believed by public health
reformers to be a central cause of high mortality among urban residents, along with the
ingestion of impure food products. Such conditions created the ideal environment for the
outbreak of infectious disease.
Each chapter also demonstrates that Fort William health officials adhered to
British and North American models of health reform, embracing both the sanitary idea
and the germ theory o f disease causation in their attempts to prevent infectious disease
from occurring. As local health authorities attempted to put these public health theories
into practice, they encountered resistance from various segments of the city community, a
development that was in no way different from those in other municipalities in the English-speaking world. Resistance to public health efforts came from political
authorities, physicians, the business community, and the city population in general, all of
whom at one time or another refused to cooperate with local health officials. This served
to limit their effectiveness. Despite this opposition, however, progress was made in
reducing the mortality rate in Fort William.


title: Localization error bounds for 5G mm-wave systems under hardware impairments

subject:
Millimeter wave communication
Array signal processing

Hardware impairments

abstract:
Localization and location aware systems are expected to be counted as one of the main services
of 5G millimeter wave (mmWave) communication systems. mmWave communication
systems are offering a large bandwidth from 30-300 GHz frequency band along with low
latency communications. Although, they use massive number of antennas at their transmitters
and receivers, their transceivers occupy a very small area, in order of centimeters.
These features make 5G mmWave communication systems an exceptional candidate for
the localization services. However, mmWave suffers from some limitations such as high
vulnerability to the environment and hardware deficiency.
The hardware used in mmWave system’s transceivers including power amplifiers and
analog/digital converters, cannot be manufactured perfectly as of high costs. Therefore, it
is highly probabilistic to see a non-linear behavior coming out of the mmWave transceivers,
known as hardware impairments (HWIs). HWIs is generally caused as a result of nonlinearity
of transmitter power amplifier and receiver low noise amplifier (LNA) as well as
analog to digital (ADC) and digital to analog converters (DAC). Moreover, HWIs is the
general form of phase noise and In/Quadrature phase (I/Q) imbalance. Because of the
mmWave’s nature, even a slight shortcoming can cause severe effects on its performance.
This thesis investigates the possible effects of HWIs on the user localization error bounds.
Towards that and focusing on line-of-sight (LOS) path, we derive the Cramer-Rao Lower
Bound (CRLB) for the user equipment (UE)’s location and orientation by starting with
a conventional two dimension (2D) scenario and then, we extend it to the realistic three
dimensional (3D) scenario. [...]

abstract:
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 density functional theory (DFT)
based approach to assessing the pJTE parameters was developed to provide a
computationally cost-effective alternative to the post Hartree-Fock procedures typically
employed. Additionally, elementary catastrophe theory models were applied to gain a
deeper insight into cases where the description of electronic structure by multiple
quantum chemical methods are incongruous with one another.
The symmetry breaking of hypovalent silicon containing compounds was studied
by examining Si-analogs of a series of a planar cyanocarbons: tetracyanoethylene
(TCNE), tetracyanoquinodimethane (TCNQ), tetracyanodiphenoquinodimethane
(TCNDQ) and tetracyanopyrenoquinodimethane (TCNP). Si-substitution generally
resulted in structural symmetry breaking of both the neutral and anionic forms which
enhanced their electron affinities. Moreover, Si-substitution was found to enhance the
singlet and triplet diradical character of the π-conjugated systems.
The choice of density functional was found to have an impact on whether or not
the pJTE was observed. This was studied in further detail by evaluating the effect of exact
exchange on the description of the adiabatic potential energy surfaces (APESs) of
disilene and 2Si TCNQ using the cusp catastrophe model. Functionals containing high
amounts of exact exchange were found not to display the symmetry breaking effect.
The elliptic umbilic catastrophe was also applied to the study of the electronic
structure of isothiirane. Furthermore, commonly used post analysis tools, the Quantum
Theory of Atoms in Molecules and Natural Resonance Theory, were critically assessed.
The results of this study resolved an open question in the literature regarding the
description of the electronic structure of isothiirane.
The pJTE parameters were evaluated using DFT by employing a model
Hamiltonian that accounts for vibronic interactions. This model Hamiltonian was fit to
cross-sections of the APES along the distorting mode. Best practices regarding the
evaluation of pJTE parameters were also described. The procedure outlined in this thesis
is applicable to the study of any pJTE problem where post Hartree-Fock methods are not
feasible.


title: Is wood characteristics mapping an opportunity to optimize the value chain in Northwestern Ontario? a case study considering eastern larch (Larix laricina (Du Roi) K. Koch) grown in the Thunder Bay District

subject: Northwestern Ontario tree species

subject: Wood characteristics mapping

subject: Tamarack Ontario Thunder Bay Region Mechanical properties

subject: Wood morphology

abstract: Wood characteristic mapping was considered as a means for optimizing the value chain of northwestern Ontario tree species. A literature review was completed which investigated the relationship of wood morphology to wood characteristics and end use as related to potential opportunities for northwestern Ontario. It was found that there was insufficient study on the area of interest to make any definitive conclusions; save that research is needed. The literature did, however, provide a general understanding on issues being assessed. Based on the findings of the literature review, a case study on mapping wood characteristics of eastern larch (Larix laricina (Du Roi) K. Koch) grown in the Thunder Bay district was completed. It was found that the greatest variability displayed by eastern larch wood grown in Thunder Bay district was between sites and radial position within trees. In all cases of statistical analysis, variance between sites was significant. Radial variability was significant for all the selected wood properties tested except for MOE perpendicular to the grain. Longitudinal or axial variability was significant in all the selected wood properties tested except for wood density.

abstract: In order to preserve valuable riparian functioning, forest harvesting in Canada attempts to protect riparian areas through the application of a no-harvest buffer zone around water bodies, and more recently through the emulation of natural disturbance patterns. Partial harvesting with maintenance of understory vegetation may emulate natural disturbance better than clearcut harvesting with conventional intact riparian buffers.


title: Vibration suppression and energy harvesting with a variant nonlinear energy sink

subject:
Vibration control
Nonlinear energy sink
Energy harvesting

abstract:
Vibration control is aimed to suppress or eliminate unwanted vibration to ensure proper
operation of machines. On the other hand, energy harvesting intends to scavenge energy from
ambient vibrations to power electronical devices such as wireless sensors. It is much desired to
achieve simultaneous vibration control and energy harvesting. A great amount of effort has been
focused on the use of a linear vibration absorber for this purpose. The shortcoming of such an
approach is that its effectiveness is limited to a narrow bandwidth of frequency.
The goal of this research is to develop a device in order to achieve simultaneous vibration
suppression and energy harvesting in a broad frequency band. Instead of using a linear vibration
absorber, a nonlinear energy sink (NES) is considered. Since it is very challenging to realize a true
NES as it requires a zero linear stiffness, this study focus on developing a variant NES that
possesses a low linear stiffness but high nonlinear stiffness. Three designs and their corresponding
apparatus are introduced. A base excitation is conducted to determine the spring restoring force in
order to character the stiffness of each design. The apparatus that best emulates the NES is chosen.
A stiff primary system and a flexible primary system are also developed by changing the primary
spring’s stiffness. The behaviors of the chosen variant NES are further investigated in two
combined system: weakly coupled one (a stiff primary system plus the variant NES) and the
strongly coupled one (a flexible primary system plus the variant NES). The transient responses of
the two combined systems are investigated numerically and experimentally. The steady state
responses of the two combined systems to a harmonic base excitation are investigated in
numerically and experimentally. The results from both the weakly coupled and the strongly
coupled systems show some typical features of the NES: 1:1 resonance, targeted energy transfer
(TET), initial energy or excitation level dependence, jumping phenomena, and strongly modulated
response (SMR), etc.


title: Female Canadian university sexual assault survivors: why they do not report

subject: Sexual assault

subject: Sexual violence

subject: Rape culture and rape myths

subject: Factors associated with the reporting of sexual assault

subject: Female university students (sexual assault)

abstract: Female Canadian university students are at a high risk for sexual victimization and as few as 5% report the assault. Various Canadian provincial governments have put forward legislation to develop and improve university sexual assault policies in order to decrease the number of sexual assault occurrences and to better support survivors. To inform such policies, it is important to understand why female university students do or do not report a sexual assault they have experienced; however there appears to be lacunae in the literature regarding factors that influence whether female university students report a sexual assault. The objective of the present study was to address the gaps in existing literature by examining how contextual, psychological, and reporting/legal factors relate to the reporting practices of female Canadian university sexual assault survivors. The findings from the present study show that the presence of physical injuries from the assault and seeking health services after the assault significantly increase the odds that survivors will report the assault to the authorities. Meanwhile, moderate to high levels of alcohol consumption (3 or more drinks) before the assault and having previously been sexually assaulted significantly decrease the odds that survivors will report the assault to the authorities. Weapon use, alcohol or drug use, psychological outcomes from the assault, fears regarding the legal process, and seeking counselling services did not significantly predict reporting. Such findings highlight that specific contextual factors and health service-seeking behaviours appear to play a significant role in reporting, while psychological factors and fear of being believed appear to be less significant than previous literature suggests.

abstract: Being a worldwide problem, water pollution has a huge impact on the mankind. The world has invested a lot of manpower and material resources after the environmental governance. Environmental pollution control has a new breakthrough with the emergence of phytoremediation technology that has the characteristics of low cost, more ecological and environmental friendly. This paper summarizes the mechanism of large aquatic plants in water pollution treatment, the status of water pollution, and the application of large aquatic plants in order to minimize the content of pollution from water. Moreover, the discussion is also based on the selection principle of aquatic plants to decrease the water pollution and safe disposal to used aquatic plants.

abstract:
Understanding the dynamic characteristics of ultrasonic guided wave in structures is important,
as it is one of the methods that are widely used in many different areas of industrial sectors and
inspections, such as Non-Destructive Testing (QNDT). The ultrasonic guided wave is
transmitted and reflected at the surface of the wave materials. A detailed study and interpretation
of mode conversion in guided wave is required.
The current research presents a theoretical study of guided wave in piezoelectric cylinders based
on the theory of elasticity. Two different methods were employed to study dispersion relations in
piezoelectric cylinders. One of them is a finite element method and the other is an analytical
method. In the analytical method, three displacement potentials are introduced to obtain
dispersion relation of guided wave modes. This method is developed primarily to cross check
finite element results.
In the finite element method, the dispersion equation has been formulated as a generalized
eigenvalue problem by treating mechanical displacements and electric potential with one
dimensional (quadratic) finite element model through the thickness of the cylinder. Computer
codes have been developed and verified by comparing with limited published results. The
numerical results are presented for different cylinders and electric boundary conditions. In the
numerical studies, three dimensional wave spectrum surfaces were generated. Discussion of
guided wave propagating in different direction in cylinders was given as well.

abstract:
Indigenous communities across Canada are courageously fighting to protect their Lands for future generations. Many settler Canadians are trying to work in solidarity with Indigenous communities to disrupt socio-ecological injustice. Efforts are being made in the fields of outdoor and environmental education to integrate social and ecological perspectives to challenge the dominant and inequitable power structures
impacting people and the more-than-human world to improve the health and sustainability of communities.
Despite these efforts, settler colonialism remains entrenched throughout Canadian institutions. Schools are still largely failing to meet the needs of Indigenous students (Dion, 2010; Haldane, Lafond, & Krause, 2012; Little Bear, 2009). Furthermore, schools are also failing non-Indigenous students by continuing to teach Eurocentric myths and perspectives. One reason for this is that settler Canadian educators have not been taught about resilient Indigenous cultures, shared colonial histories, or their own complicity in contemporary socio-ecological colonialism. I argue that settler environmental educators need to decolonize ourselves and our teaching praxes in order to shift towards ethical relationality (Donald, 2012) or respectful relationality (Korteweg, personal communication) with Indigenous peoples and Lands. To date, however, little research exists that conceptualizes decolonizing for settler Canadians or that seeks to understand how to facilitate these complex and lifelong processes.
Working from an Indigenist–decolonizing theoretical framework (Smith, 1999; 2010; Wilson, 2001; 2007) and guided by auto-ethnographic methodology (Denzin, 2014; 2006; Ellingson & Ellis, 2008; Anderson, 2006), I employ reflexive narrative vignettes and constructivist grounded theory analysis (Charmaz, 2003; 2006; Kovach, 2010) to examine the factors and experiences that facilitate and/or prevent settler Canadians’
capacity to shift towards respectful relationality with Aboriginal peoples. I aim to provide an in-depth model of “unsettling the settler” (Reagan, 2010) through my own self-study in order to expand the literature on settler decolonizing and to theorize fundamental moves that educators in general and environmental educations in particular need to experience in order to deepen our decolonizing understandings.
Through my own critical self-study, I offer 10 “settler moves to respectful relationality,” based on experiences that support decolonizing. They include: Land-based experiences and acknowledgement of Indigenous Land; engagement with resilient Indigeneity and relationships with Indigenous peoples; critically reflexive autobiographical work; and connections to one’s own cultural heritage and community.

abstract:
The protection of water resources is becoming one of the most critical issues afflicting people
globally.  Novel, robust, efficient, and environmentally compatible technologies for the
treatment of wastewater and the analysis of water quality are urgently required. Fortunately,
with the development of electrochemistry and new materials, promising and environmentally
benign approaches for the treatment of wastewater and the assessment of water quality are
currently available.
An advanced and efficient approach known as EDI was developed for the continuous
separation and recovery of Cr(III) and Cr(VI).  Firstly, we developed a new analytical method,
which combines UV-Visible spectroscopy and Inductively Coupled Plasma Atomic Emission
Spectroscopy (ICP-AES), for the determination of the concentrations of both Cr(VI) and
Cr(III) in a mixed solution, and for monitoring the EDI process. Secondly, we determined the limiting current and systematically studied the effects of different applied currents on the removal of Cr(VI)
as well as on the recovery of Cr(III) and Cr(VI). Thirdly, the influence of the level of saturation of the ion-
exchange resins was assessed in terms of both removal efficiency and energy consumption.
The use of fresh ion-exchange resins for the EDI process were initially found to be very effective for the removal of both Cr(VI) and Cr(III).  Both resins became increasingly saturated with each subsequent cycle, resulting in a gradual lowering of the cell voltage.  The continuous and highly efficacious removal of highly toxic Cr(VI) (> 99%), and low energy consumption make the EDI process attractive for the
separation and recovery of Cr(VI) and Cr(III).

abstract:
My portfolio is focused on team-based learning (TBL) in the area of health sciences education. My interest in this topic stems from my work in the Postgraduate Medical Education (PGME) setting where I work as an instructional designer. I believe that TBL is a teaching methodology that, when implemented with proper support and guidance, can enhance learning by providing a structure around a flipped classroom model while providing active learning opportunities.
In PGME, residents have completed multiple levels of schooling, including their medical degree, in order to enter their final years of training to become a licensed physician. Learners spend the bulk of their time completing clinical rotations and only attend in class academic sessions for a small amount of time. Academic sessions vary by program, but time spent in academics is usually about one half-day/week with the rest of a learner’s time being spent on rotation at clinics, hospitals, health units, etc. Academics are normally delivered by different presenters each week and topics vary from week to week. Further to that, residents are not assessed or graded on their performance in academic sessions. Due to the way that academic sessions are organized for PGME programs, there are distinct differences from traditional higher education programs that need to be thought about when designing curriculum delivery. There are many promising strategies used within the TBL method and some challenges to overcome specific to PGME implementation.
This portfolio aims to provide a current state view of the integration of TBL into higher education, with a focus on health sciences education. In doing so, this portfolio will share best practices strategies for implementing TBL from an instructional design perspective while adhering to defined TBL principles.

abstract:
The Minnesota Multiphasic Personality Inventory (MMPI/MMPI-2), the most frequently
used measure ofpersonality and emotional frmctioning in clinical neuropsychological
settings, does not meet current psychometric standards. The Personality Assessment
Inventory (PAI; Morey, 1991) is a promising alternative to the MMPI, however its
usefulness or clinical utility has not yet been formally examined. The present study was
conducted to identify items ofthe PAI that might reflect neurological symptoms and to
compare scale scores before and after adjustment for this content. AU 344 PAI items were
examined by three neurospecialists. Twenty items were identified by these raters as
representing physical effects produced by acquired brain injury (ABI) and experienced by
at least one in four patients. Fifteen ofthese items were keyed on either the Somatic scale
or the Schizophrenia Thought Disorder subscale. PAI profiles for 62 ABI patients were
corrected for this content using the method of Gass (1991) for prorating scale scores on
the MMPI-2 (i.e., differential endorsement neurological vs. non-neurologcal items).
Although this correction significantly reduced mean sample scores across aU affected
scales (F [8, 54] = 45.22, p < .001), the frequencies ofT scores > 69 were most reduced
for the Somatic scale, from 32% to 8%, and the Schizophrenia Thought Disorder
subscale, from 45% to 16%. Difference scores between ABI and normative responses
were calculated. Nine of20 neurological items were among the highest discriminators
between these two populations.


title: Implications of the metaboreflex on cerebral blood flow: physiological responses and assessment strategies

subject: Cerebral blood flow (exercise)

subject: Neurogenic response to exercise

subject: Cerebrovascular regulation during rest and exercise

abstract:
Exercise is responsible for acutely modifying cerebral blood flow (CBF) during an exercise bout,
and eliciting chronic increases to resting CBF in trained individuals. Research to date has
focussed on the individual mechanisms such as neural metabolism, arterial gas concentration and
blood pressure that are responsible for CBF control and are altered by exercise. Altering theses
mechanisms at rest, and comparing changes in CBF has been how researchers study the CBF
response to exercise. The purpose of this thesis was to provide a scoping review of an important
system for the regulation of the CBF exercise response: the exercise pressor reflex (EPR). A total
of 30 neurogenic, and 12 cerebrovascular studies were reviewed in a two-part scoping review.
The review of cardiovascular responses to varying post exercise muscle ischemia protocols
demonstrated a large variance between studies, and a methodological variety of exercise
intensities and durations. The scoping review of the CBF research demonstrated a variety of CBF
responses to EPR stimulation, where CBF increased, decreased, or remained unchanged.
Decreases in arterial carbon dioxide concentration, caused by hyperventilation, were found to
disguise the effect EPR stimulation on CBF in several of the investigations. When arterial carbon
dioxide was experimentally clamped, increases in CBF appear to correspond with arterial blood
pressure (BP) responses. Furthermore, microvascular changes in CBF occurred in some instances
while macrovascular flow was unchanged, perhaps indicating a region effect of the EPR on CBF.
Overall, it has been shown that the EPR affects CBF by manipulating carbon dixide, BP, and
perhaps myogenic factors, depending on region. The influence of these factors requires further
experimental research. Future research that manipulates carbon dioxide and BP levels while
assessing cerebral artery diameter and blood flow velocity is recommended to address the
inconsistencies discovered in the current review.

abstract: Under the Ontario Forest Accord, several parcels of land have recently been designated as protected areas reducing the area available for forest management. As a result, forestry companies will likely have to intensify timber production using post harvest silviculture on remaining industrial forestry land to yield the same volumes achieved from fewer operable hectares. I used a chronosequence approach (stands 15-57 yrs) to investigate the question: "Does post-harvest silviculture change forest composition and structural attributes at the stand level?" I sampled overstory, standing dead-wood components, and woody debris of forty-three upland mesic stands in the Gordon Cosens Forest, Kapuskasing, Ontario. Stands were selected to address potential differences in structural attributes resulting from three silvicultural intensities (harvest with no silviculture, harvest with planting and with herbicide tending, and harvest with site preparation, planting, and application of herbicide), across the chronosequence.

abstract:
Between World Wars I and II, the ethnic Germans in Canada strove to retain their
language and culture. The impetus came on the heels of the Great War because lingering
anti-German sentiment and assimilationist policies threatened to destroy their culture and
traditions. Canada’s ethnic Germans were not alone in such endeavours, as German
communities around the world also attempted to retain their identity. Within Germany,
there flourished a movement designed to aid and foster the protection of German
ethnicity around the globe. The movement encompassed private, semi-official and
official agencies. The scope of their activities touched upon every aspect of ethnic
retention and affected every country in which a sizable German element resided.
Funding, materials, and guidance flowed from Germany to the ethnic Germans abroad,
greatly influencing the direction and content of their attempts to retain their heritage, and
this included the ethnic Germans in Canada. This thesis will give perspective to
Deutschtumsarbeit in Canada by placing it within the context of the global movement
orchestrated from Germany.

abstract:
I examined the forage base of Henderson Lake, Ontario
following collapse of its walleye stock due to overexploitation,
and an inexplicable decline of the ninespine stickleback
population. In response to these events a very large yellow
perch year class was produced. Subsequently, adult perch density
increased while growth, mortality, size at maturity and
fecundity decreased. Continued stunting in young yellow perch
could not be attributed to direct interspecific competition with
abundant shiners. As northern pike activity increased shiner
activity declined but yellow perch remained active and available
as prey. Thus, small perch occurred much more frequently in the
diets of northern pike than did shiners. The large numbers of
stunted yellow perch may provide excellent forage for enhancing
the recovery of the walleye population.

abstract:
Lake Simcoe, Ontario, Canada, a large southern Ontario
glacial lake, has been affected by multiple environmental
stressors throughout its history. This study uses testate
amoebae paleodistribution to reconstruct the environmental
conditions of Lake Simcoe's fringe wetlands before and during
the Anthropocene.
Testate amoebae are unicellular shelled protists that
inhabit almost every environment in the world from sandy
marine beaches to all freshwater and terrestrial habitats.
Their rapid asexual reproduction makes testate amoebae
sensitive indicators of short-lived environmental change.
Paleolimnological and paleoecological investigations using
testate amoebae have been used to describe hydrology, pH,
trophic status, land use, climate change, forest fires, oxygen
concentrations, metal contamination and other variables.
Using compound microscopy techniques, testate amoebae
assemblages were identified and tabulated from processed
sedimentary cores extracted from fringe wetlands in Lake
Simcoe and Tub Lake, with the latter lake used as a reference
to assess anthropogenic impact during the Anthropocene. One
core, taken from the outlet area of Lake Simcoe, was used to
reconstruct the past variability of the paleoenvironment while
all four cores were used to reconstruct Anthropocene
paleoenvironments.
Prior to European settlement three distinct testate
amoebae communities inhabited the Victoria Point wetland area
based on hydrologic variability: an arctic-like, oligotrophic
testate amoebae community dominated by alkaline, lacustrine
species; a CaCo3-based community dominated by mesotrophic
calcipiles; and an "early fringe wetland community" dominated
by aquatic and soil-based species.
The anthropogenic activities of the last ~200 years lead
to a rapid paludification of the shoreline in all Lake Simcoe
wetland locations. Anthropogenic activities have also produced
a constant state of disturbance along the shoreline where the
mean rate of change in the testate amoebae community since ~AD
1300 (0.46) is greater than the rate of change in the
preceding record (0.40). Some of this change is also
attributable to recent climate change particularly in the
winter and spring, and possibly to the introduction of the
Zebra mussel in the mid 1990s.
While similarities in the response of testate amoebae
assemblages across wetlands do exist, this study has also
found that local activities have affected testate amoebae
assemblage paleodistributions, species richness and diversity.

Bearing fault diagnosis

abstract: Induction motors (IMs) are commonly used in industry. Online IM health condition monitoring aims to recognize motor defect at its early stage to prevent motor performance degradation and reduce maintenance costs. The most common fault in IMs is related to bearing defects. Although many signal processing techniques have been proposed in literature for bearing fault detection using vibration and stator current signals, reliable bearing fault diagnosis still remains a challenging task. One of the reasons is that a rolling element bearing is not a simple component, but a system; its related features could be time-varying and nonlinear in nature. The objective of this study is to investigate an online condition monitoring system for IM bearing fault detection. The monitoring system consists of two main modules: smart data acquisition (DAQ) and bearing fault detection. In this work, a smart current sensor system is developed for data acquisition wirelessly. The DAQ system is tested for wireless data transmission, consistent data sampling, and low power consumption. The data acquisition operation is controlled by using an adaptive interface. In bearing fault detection, a generalized Teager-Kaiser energy (GTKE) technique is proposed for nonlinear bearing feature extraction and fault detection using both vibration and current signals. The proposed GTKE technique will demodulate the signal by tracking the instantaneous signal energy. An optimization method is proposed to enhance the fault-related features and improve signal-to-noise ratio. The effectiveness of the proposed technique is verified experimentally using a series of IM tests. The robustness is examined under different operating conditions.

abstract:
Woody biomass contributes less than 6% of total energy production in Canada. Based on
previous data relating to the supply, quality and economic potential, this compilation of relevant
data provides an estimation on the available sustainable supply of woody biomass in
Northwestern Ontario. This thesis explores the availability and thermal potential of biomass in
the form of forest harvest residue and underutilized tree species in Northwestern Ontario and the
potential for increased energy production at various existing facilities in the region. This study
summarizes previously published data on availability, quality and economic feasibility of
biomass acquisition in the region. It was estimated that there is 40.2m3/ha of available woody
biomass feedstock throughout the study area, with an average thermal potential of 20.65 Mj/kg to
21.28 Mj/kg. These results indicate a sufficient supply with adequate thermal potential is readily
available in the region. The total cost of procurement of biomass in the region averages 44-
46$/gt, which indicates an economically feasible scale based on the technically available
biomass. Summaries provided in this study quantify objective data on these objectives to
determine the feasibility of increased biomass energy production in the region.

Binge eating and smoking

abstract:
Applicability of the stage of change and decisional balance constructs for bingers and
smokers was examined in a study of 191 participants; bingers (n = 47), smokers (n = 80),
and controls (n = 64). The Stage of Change Inventory (SCI) was cross-validated with the
University of Rhode Island Change Assessment (URIC A) scale and used to assign
bingers and smokers to one of five stages of change; precontemplation, contemplation,
action, maintenance, and recovery. Psychological distress, the characteristics of binge
eating and smoking, and the pros and cons of behavioural change were evaluated as a
function of the stages of change. Although an increase in the con scores from
precontemplation to action did not support the weak principle of the decisional balance,
an increase in the pros of behavioural change from precontemplation to action provided
support for the strong principle for bingers and smokers. Results of the Brief Symptom
Inventory (BSI) indicated that psychological distress was not related to stage of change
for bingers or smokers. However, bingers were found to score significantly higher than
controls on the Global Severity Index (GSI) of the BSI. Several measures were used to
further explore the phenomenology of binge eating and smoking. Results of the Binge
Eating Adjective Checklist (BEAC) and Smoking Adjective Checklist (SAC) suggested
that both behaviours serve a function in reducing the amount of psychological distress
experienced by participants. For bingers, degree of loss of control and negative affect
were found to vary as a function of stage of change, with precontemplators experiencing
the least negative consequences associated with their behaviour and action-takers the
most. The overall findings support the applicability of the transtheoretical model for
bingers and smokers and further suggest that stage of change is related to characteristics
of binge eating such as negative affect and loss of control.

abstract:
The detection and identification of disease-causing parasites via DNA and the
polymerase chain reaction (PCR) offers a new approach for quick and efficient disease diagnosis.
Three nucleic acid based technologies have been developed and optimized for the identification
of six species of parasites that cause disease, and designed to amplify small fragments of DNA
likely to remain in archaeological material. Two methods involve a species-specific
identification by examining four gene fragments, one of which has been designed as a multiplex
PCR to minimize the time required for diagnosis. The third method involves the use of one
species-specific gene target per parasite in a multiplex PCR for the detection of multiple
parasites in one reaction to expedite the testing process and confirmation of the disease in
question in a clinical setting. Sensitivity and specificity have been proven through the use of a
1/1000 diluted DNA template and sequencing of products confirmed the presence o f each
species analyzed. With increased sensitivity, a less invasive sampling procedure would be
required from the patient. Also, the earlier the presence of parasites in the tissues is detected, the
earlier the diagnosis would occur. Tissues that contain very few parasites and had been
classified as previously unusable for diagnosis or tissues from older medical cases can be
analyzed for the presence of disease and the identification of causative species. The successful
application of the singleplex PCR technique to Plasmodium falciparum and Leishmania
degraded DNA samples leads to the feasibility of success for the multiplex PCR techniques
involving degraded DNA analyses. Therefore, this methodology may be applied to samples of
unknown disease content to either include or exclude the agents of disease. Future directions
may extend these analyses to include a range of other agents of disease, thus allowing for the
determination of disease antiquity through degraded DNA analyses.

abstract:
Electroencephalogram (EEG) analysis has garnered attention in the research domain
due to its ability to detect various neural activities starting from brain seizures to a
person’s concentration level. To make it more beneficial for the users, it is important
to miniaturize the currently available clinical-grade large EEG monitors to wearables
which can provide decisions at the edge. Traditionally, for performing such analysis, the
raw EEG signals are collected at the edge which is then transferred to the cloud where
the data is interpreted and forwarded accordingly. However, this method of transferring
the user data for analysis poses a risk of security and privacy breach as well as consumes
a considerable bandwidth and time which makes it inefficient in terms of scalability.
In this vein, we investigated on transferring the Artificial Intelligence (AI)-logic of the
analysis to the sensors, so that a localized decision can be made on the edge, without
transferring the data, thus saving precious bandwidth and restoring privacy of the users.
However, the main challenge in achieving such a scenario is the devices’ inability to
perform complex computations due to its resource constraints. Hence, we have explored
various AI-based techniques throughout this thesis to find out a lightweight model
which will be able to give a decent performance while consuming lower resources. We
have validated our candidate models in various use-cases throughout the chapters to
compute the performance of the AI models. It is believed that, this type of analysis can
encourage the sensor foundries to integrate AI-logic with wearable sensors, to conduct
localized EEG analysis on the sensor level, which will be more practical, cheaper, and
scalable.


title: Effects of low dye taping on foot pressure in subjects with planter fasciitis

subject: Fasciae (Anatomy) Inflammation Treatment

subject: Gait analysis

subject: Plantar fasciitis

subject: Heel pain

abstract:
The purpose of the investigation was to analyze the effect of low dye taping on
the vertical foot pressure and the path of the centre of pressure (COP) in individuals
with plantar fasciitis. Ten subjects (8 females and 2 males) meeting the specified
diagnostic criteria were included in the study. The mean age of the subjects was 28.4
years. Each subject was tested under two conditions, walking with low dye taping and
walking without. Vertical foot pressure and COP was measured using the F-Scan Gait
Analysis System. Vertical foot pressure was significantly decreased in the rearfoot with
the application of low dye taping during contact ( M = 0.29, SD = 0.37, t (9) = 2.46,
p < 0.05 ). Subjects did not demonstrate a significant change in pressure in the midfoot
during midstance ( M = 0.18, SD = 0.51, t (9) = 1.12, p > 0.05 ). Subjects also did not
demonstrate a significant change in pressure in the forefoot during propulsion
( M = 0.08, SD = 0.59, t (9) = 0.46, p > 0.05 ). Analysis of the COP curves revealed no
consistent change. Throughout contact, midstance and propulsion there was no
tendency towards medialization In the COP. The results of this study supports the
research in that low dye taping decreases the amount of pressure transmitted through
the foot during contact. However, there was no consistent change In the COP curves
with the application of low dye taping failing to support the inferences reported by some
researchers. Based upon the results of this investigation low dye taping decreases the
foot pressure under the rearfoot during contact. Low dye taping has no consistent
effect on the COP, and does not produce any medialization of the COP thereby
increasing tension on the plantar fascia. Further study should be pursued analyzing
the effects of low dye taping.

abstract:
Bald eagles {Haliaeetus leucocephalus alascanus) have been declared an endangered
species in Ontario. For protection of bald eagles from behavioural and habitat
disturbance, their nests are defined as Areas of Concerns by the Ontario Government.
To direct the management of these areas, the Ontario Ministry of Natural Resources
reviewed the available literature and produced the Ontario Management Guidelines.
However, the information available on Northern Ontario's bald eagles is limited,
referring to the Lake of tire Woods Area only. To study bald eagles and evaluate
Ontario's guidelines I gathered and analyzed data from across Northern Ontario on
bald eagle habitat (1990, 1991, 1992), the effect of timber management on their
reproduction (1990) and bald eagle distribution (1990). Data were analyzed
univariately and I developed logistic regression models for topographical, limnological
and vegetation characteristics. Variables important for defining the probability of a
nest occurring include lake dimensions, stand density and tire availability of super-dominant,
accessible perch trees. Of the models developed, two had practical
implications: a limnological model which could be used to define potential foraging
lakes and thus prevent unnecessary surveys and a vegetation model which could be
used to evaluate habitat quality. Natality rates of bald eagles did not differ
significantly among areas harvested according to guidelines, harvested without
reference to the guidelines and undisturbed. The habitat features of forests,
surrounding Northern Ontario bald eagle nest sites are similar to elsewhere except for a
greater significance of perch trees. This justifies the Ontario Ministry of Natural
Resource's use of available data, but the guidelines may underestimate the number of
large perch and nest trees in optimal bald eagle habitat.

abstract:
The creation of The University of Canada North, by federal letters patent in 1971, marks
the beginning of a revealing episode in northern Canadian history that spans almost
fifteen years. The brain-child of Toronto lawyer Richard Rohmer and thirty residents of
the two territories, The University of Canada North (UCN) appeared to provide suitable
and useful post-secondary education to all northerners regardless of ethnic background,^
to control and contribute to northern research, and, by its very existence, to grant
northern society a cachet of stability that it did not yet appear to have. The fact that it
was initiated not by government, but by a group of interested individuals placed the UCN
both in an emerging northern practice of attempting to find northern solutions to
northern problems and in the growing northern rejection of its traditional colonial
relationship with the South. The growing strength of the territorial governments and
northern First Nations organisations was reflected in northern society by a popular sense
of pride and an unwillingness to continue in the established colonial relationship with the
federal government This attitude resulted in an intense and widespread desire to wrest
control of day-to-day living and governing from the distant hands of the Department of
Indian Affairs and Northern Development Different groups in the North responded in different ways. The First Nations established organisations to address their concerns.
Non-Aboriginal northerners responded by creating societies to provide local solutions and
local voices to the insufficiencies they saw. The territorial governments expanded their
jurisdictions through a series of transfer agreements with the federal government

abstract:
The purpose of this study was to determine whether the ingestion of
an energy-free aspartame beverage (ASP) (99 mg aspartame/L) would
influence endurance performance relative to a water (WAT) trial. Nine
trained male cyclists underwent two cycle ergometer trials to exhaustion at
75% VO2 max. Experimental beverages were ingested every 15 minutes
beginning 45 minutes prior to cycling. Mean (± SD) exercise times to
exhaustion were 100 ± 28 minutes for the ASP trial and 99 ± 34 minutes
for the WAT trial (p>.05). Respiratory exchange ratio and heart rate did
not differ in response to the treatment condition. Ratings of perceived
exertion were significantly elevated in the ASP trial but only at the
initiation of exercise. It was concluded that the ASP beverage did not
impair endurance performance relative to WAT.

abstract:
Pulp and paper mills generate a significant amount of organic waste (primary and secondary
sludge) that requires treatment and disposal. Currently, pulp and paper sludge (PPS) is either
dried for incineration or used for landfilling. However, the dewatering and drying of sludge
before incineration is an energy extensive process and landfilling is associated with a high cost
and low public acceptance, the practices of landfilling will tend to decrease. Recently, anaerobic
digestion is considered a cost-effective alternative to a small environmental footprint and has
been researched widely. Similarly, anaerobic digestion of PPS has the limitations of a large
reactor size, high capital cost, and reduced quality of effluent. Thus, it is highly desirable to
search novel technologies for PPS treatment and disposal. In this study, a new insight was that
thermophilic anaerobic membrane bioreactor (ThAnMBR) was developed for PPS treatment and
disposal for biogas production because it can overcome some advantages of conventional
anaerobic digestors.
In this study, a laboratory-scale ThAnMBR was operated for 328 days to assess the biological
and membrane performance of the ThAnMBR at different hydraulic retention times (HRTs) and
different types of pulp and paper secondary sludge. In the first part of this thesis, the biological
performance of ThAnMBR are discussed by effluent, organic loading rate (OLR), chemical
oxygen demand (COD), biogas production rate, biogas composition, biogas yield and suspended
solid destruction. The results showed that the performance of a higher HRT is better than a low
HRT, but the performance of ultrasonic pretreatment on PPS does not improve all properties. In
the second part of this thesis, the membrane performance of ThAnMBR was discussed by: flux,
transmembrane pressure (TMP), membrane fouling, particle size distribution, extracellular
polymeric substances (EPS), soluble microbial products (SMP), morphology and pore size
distribution. The results suggest that ThAnMBR is feasible for PPS treatment, but the membrane
fouling should be minimized. Operating ThAnMBR at a higher HRT is more attractive than at a
lower HRT from the biological performance point of view.

abstract:
Regular long term hemodialysis is the accepted method of
treatment for patients with advanced renal failure. While it is
effective in maintaining a patient in reasonably good health for long
periods of time many problems remain, not the least of which is metabolic
bone disease. This work was undertaken to determine the effects of
hemodialysis on serum electrolyte and parathyroid hormone levels. It
was found that the dialysis regimen was effective in maintaining
electrolyte and acid base balance. There was no definite evidence
to suggest that hemodialysis contributed to the osteodystrophy which
was evident in some of the patients.
