abstract:
Aboriginal education reform policies, Truth and Reconciliation initiatives, and climate change indicators signal opportunity and an urgency for action to effect positive change through relationship with Aki1. Aboriginal peoples’ ancient and wholistic ways of knowing, being, doing, and feeling are touchstones to support timely transformative processes in education and Canadian society. Current educational initiatives emphasize learning Aboriginal content and the integration of historical perspectives and contemporary arts into the Ontario curricula. This case study of 17 participants in a grade 4/5 classroom explores a research journey in northeastern Ontario demonstrating how the oral tradition and an Anishinaabe storywork Circle pedagogy
create conceptual space for Anishinaabe ecological relational knowledge within the urban public school classroom. An Anishinaabe shared learning process devoid of power imbalance draws on the life experience of each student and educator in a culture and land-based approach. This study addresses the following research questions: What is Anishinaabe ecological relational knowledge and what principles and concepts of Anishinaabe ecological relational knowledge are made visible in a public school classroom? How is Anishinaabe ecological relational knowledge socially enacted in the classroom? How does the teacher's perception of Anishinaabe ecological relational knowledge transform their pedagogy? A critical Indigenous2 research theory and qualitative methodological approach bring forward a narrative inclusive of teacher and
elementary student voices and participant researcher reflections and query.
1 Aki is the Anishinaabemowin term for "Land". Anishinaabemowin refers to the Aboriginal languages of
the Anishinaabek people, spoken by the Algonquin, Chippewa, Delaware, Mississauga, Odawa, and Ojibway and Pottawatomi people of the Great Lakes Region.
2 The term Indigenous refers to the first peoples that occupied the continents of the world and is used in this
research context to refer to all first peoples-unique in our own cultures-but common in our experiences of
colonialism and our understanding of the world (Wilson, 2008, p. 15).                                                           Anishinaabe cultural ecological relational knowledge refers to a specific area of Indigenous knowledge that suits the study's local context regarding Anishinaabe cultural origins, linguistic family, and community traditions. An animated learning process and experience incorporates life experience, relational collectivity, and inner knowing for Anishinaabe cultural ecological relational knowledge regarding the self in relationship with Aki and each other. The ‘school yard as classroom’ is utilized and this is especially supportive for First Nation students in transition to the city. Students’ and educators’ engagement in an inclusive community of respect and mutual understanding supports exploration of biophilia (the love of nature) and balanced
relationships. The incorporation of Anishinaabemowin (Ojibway language) conveys worldview
perspectives and exemplifies the Indigenous paradigm and ways of knowing. The Anishinaabe storywork Circle process builds identity and supportive relationships which are strongly associated with school success of particular relevance for Aboriginal student engagement in school. Classroom teacher praxis is stimulated in response to Anishinaabe ecological relational knowledge and an Anishinaabe storywork Circle pedagogy. A robust process for change emerges through an examination of ecological systems theory. The impacts of relationshipbuilding, creation of a kind, respectful and inclusive classroom environment to interrupt systemic
hegemony and racism are discussed.

abstract:
Methane emissions from peatlands have been researched for decades, although our
understanding of methane production at microbial scales is still limited, and this may hamper our
ability to predict methane emissions from site-to regional- to global scales. Here, a multi scale
approach is used to expand on current knowledge related to the controls and the microbial
community responsible for methane production within peatlands. For the first time, an analysis
of methane production from a global, coordinated sampling effort was done using a standardized
laboratory methodology. Site pH and plant communities were shown to be the best predictors of
methane production at the global scale, while peat organic chemical characteristics and abiotic
factors including temperature, moisture, and nutrient concentrations, were also shown to be
important. Around 5% of samples showed disproportionately high methane emissions compared
to CO2. The second research project narrowed focus to a regional scale: peatlands in the
Sudbury, ON region were evaluated to assess the role historic and contemporary smelting
activities, and subsequent metals and sulfur deposition, have had on the methanogen community
composition and methane production. In comparison to most peatland studies, the methanogens present in impacted sites were largely unclassified at the order level and production of methane
was dramatically decreased compared to the reference locations. The third research project in the
thesis focused even more exclusively at the microbial scale: enrichments of peat were used in an
attempt to isolate novel methanogens. While no pure culture isolates were obtained, novel
methanogens at the genera and species level where obtained from five of the seven known
methanogenic archaeal orders. The case is made that obtaining enrichment (mixed) cultures is an
important, underused methodology for discovering and learning about novel methanogens, which
have very tight, perhaps inseparable, syntrophic relationships with other anaerobic microbes.  Combining culture techniques with modern sequencing technologies was explored as a way
forward in obtaining novel species genomes and related growth conditions. Taken together, the
overall controls on methane production at global and local scales are commonly peat pH, plant
community composition, and peat quality, while the methanogen communities responsible for
methane production remain largely unknown and underrepresented in culture collections
highlighting the need for further enrichment and isolation work.

abstract:
Background: The school environment is an important contributor to children’s health. This thesis
assessed student perceptions of physical activity, eating behaviors, and learning engagement
throughout the school day.
Methods: Surveys were distributed in grades 3 and 6: three schools using the Balanced School
Day (BSD) schedule, and three using the Traditional School Day (TSD) schedule. Students selfreported
physical activity, eating behavior, and learning engagement, at key times in the school
day. Student perceptions by grade, gender, and schedule were examined. Data were expressed as
frequencies and percentages and the variables were cross-tabulated and analyzed using Chi-
Square analyses.
Results: In total, 173 students participated in this study (response rate of 54%). Girls self reported being less physically active than boys at recess. Grade 3 students experienced hunger
more frequently than grade 6 students. There were no significant hunger or physical activity differences
between schedule types. All students reported high hunger and lower learning engagement
at the end of the school day.
Conclusion: We recommended age/gender specific schedule modifications to reduce hunger, and increase physical activity and learning engagement at school.

abstract:
The origin of the Platreef in the Northern Limb of the Bushveld Igneous Complex (BIC) and
its correlation as the stratigraphic equivalent of the Merensky Reef in the Eastern and Western
limbs has been long debated. Strontium isotope stratigraphy across the Platreef was completed on
drillcore from the Turfspruit farm to test a possible correlation with the Merensky Reef. The
results show a significant 87Sr/86Sri shift from ~0.7060 to 0.7090 through the mineralized section
of the Upper Platreef, which decreases to 0.7074 and then increases again and stabilize at ~0.708
in the Main Zone. This matches the isotopic shift previously documented through the Merensky
and Bastard Cyclic units in the Eastern and Western limbs of the BIC. This coincident shift in
87Sr/86Sri is substantive evidence to confirm that the mineralized intervals in the Upper Platreef
are the stratigraphic equivalent to the Merensky and Bastard Cyclic units. This thesis also
documents the presence of micro-cycles within magmatic units (up to 350 cycles identified
through 215 meters). Working hypotheses linking the micro-cycles to thickness of mineralization
are suggested. Testing those hypotheses are outside of the main scope of this study and are
suggested for future work.

abstract:
This thesis considers health promotion materials on dementia for Indigenous people using health
literacy and cultural safety as guiding frameworks. The author examined the question “How can
we develop health promotion materials about dementia to meet the needs of Indigenous peoples
living in urban Northern Ontario?” using two decolonized approaches to community-based
participatory action research. Two-eyed seeing combines biomedical information with
Indigenous knowledge to develop fact sheets. An understanding of local tribal teachings guided
the research locally. Methods involved qualitative data analysis of two focus groups and five
one-on-one interviews exploring the fact sheets’ appropriateness. Results suggest the need for a
shared understanding of Indigenous and Western cultures; improved cross-cultural
communication; the importance of grounding health promotion materials in culture; and,
strategies for dementia awareness in Indigenous health literacy. These research findings can be
translated to inform policy and practice through key recommendations regarding the
development of health promotional materials.

abstract:
This thesis applies some teachings and methods of Michel Foucault (1926-1984) to
critically analyze the history and current practices related to the United States’ “War on Drugs.”
By tracing the history of the Drug War and placing drugs and drug addicts in a less hyperbolized
context than traditionally presented in the media and in drug war propaganda, it is possible to
critique what can be seen as a war on drug addicts and to gain insight as to its hidden motives,
relevant patterns, social implications and ultimately its effect on American culture and society
and notably its deleterious effects among America’s people of colour and urban communities.
With respect to Foucault’s concept of a race war and the notion that “politics is the continuation
of war by other means,” the War on Drugs can be contextualized in terms of a discourse of
perpetual war that rages even in times of putative peace.

title: Population dynamics of reintroduced elk (Cervus elaphus) in eastern North America

subject:
elk
population
eastern North America

abstract:
Studies that focus on identifying factors that influence reintroduction success have often taken an
individual population approach; however, investigating multiple populations can provide
additional insight. The overall objective of this research was to emphasize the value of using
within- and among-population approaches to identifying factors that influence the population
dynamics of a reintroduced species. Elk (Cervus elaphus), a species that was extirpated from
eastern North America during the late 1800s, has been reintroduced to portions of its former
range over the past century through several initiatives. Today, there are several established
populations across eastern regions of the USA and Canada, for which extensive monitoring data
are available, creating an opportunity to investigate reintroduction success. I aimed to use these
data to identify factors associated with changes in the survival and population growth rates of 10
reintroduced elk populations across eastern North America. More specifically, I: (1) performed a
literature review detailing the history of elk reintroduction in eastern North America over the
past century, (2) identified factors associated with the variation in population growth rates
(reintroduction success) for 10 reintroduced elk populations using an among-population
approach, (3) identified and assessed how climate affected the population growth rates of 7
reintroduced elk populations, and (4) investigated direct causes of mortality (predation and train
collisions) associated with a single elk population experiencing low population growth.
Although the number of successful elk restoration attempts has increased over the past century,
there has been substantial variation in population growth rates among reintroductions. Major
iv
causes of elk mortality in restored populations differed between the pre- to post-acclimation
phases of reintroduction. Population growth rates were negatively related to the percentage of
coniferous forest within elk population range, suggesting that expansive areas of coniferous
forests in eastern North America may represent sub-optimal elk habitat.
The Burwash elk population in Ontario had low growth rate compared to most other populations
reintroduced into eastern North America. Predation and train collisions were the most important
source of mortality for this population. The number of annual elk-train collisions, as well as their
locations, were monitored and recorded over 14 years. Collision locations were highly sitespecific
and were positively correlated to the proximity of bends in the railway. By relating the
number of annual elk-train collisions to various climate factors, I found that collision rates were
positively related to snow depth. By analyzing field camera data, I found that elk used the
railway mostly during the fall and spring, when elk commonly travel to and from wintering
grounds. However, by examining VHF telemetry locations, I determined that elk were closer to
the railway in winter than in any other season. Railways likely are perceived by elk as easy travel
corridors, especially in the winter, and deep snow might prevent escape from oncoming trains.
Black bear (Ursus americanus) and wolves (Canis lupus) were the major predators of elk in the
Burwash population. White-tailed deer (Odocoileus virginianus), elk (Cervus elaphus), and
moose (Alces alces), were the ungulate prey species available to both predators. To determine if
predators prefer one ungulate species over another, and to identify which predator species is
likely to have a greater impact on elk survival, I investigated predator diets. To compare rates of
v
ungulate use by predators in relation to prey availability, I calculated the relative abundance of
each ungulate species. I found that wolves used juvenile and adult elk as their primary ungulate
prey in greater proportions in comparison to their availability. Bears on the other hand, tended to
use all ungulate species in proportion to their availability.
Climate is well known to affect ungulate population dynamics; however, several factors (e.g.:
density, predator presence), can govern the response. Relating the annual growth rates of 7 elk
populations to various climate factors I found that responses were population specific. Increased
annual snow fall was associated with declines in population growth rates for 2 of the 7
populations assessed and only 1 population responded negatively to increased summer
temperatures. Climate likely interacts with other environmental variables to influence
fluctuations in annual population growth rates which warrants further investigation.
The results of this research will contribute to informed planning of future elk reintroductions and
should support development through improved management. In addition, this research highlights
the importance of using within- and among- populations approaches to investigating factors that
influence elk reintroduction success.

subject: Blanding's turtles (Emydoidea blandingii)

subject: Population viability analyses (PVAs)

subject: Large-scale predation event

subject: Recovery strategies

subject: Nest protection

abstract:
Mass mortality events (MMEs) are rapidly occurring and localized events, and have been
reported to remove up to 90% of individuals in a population. MMEs can be especially damaging
to population persistence for long-lived species, such as chelonians. While MMEs have been
regarded as rare events, they are predicted to occur with increased frequency as environmental
stochasticity associated with climate change increases. Unfortunately, a limited understanding of
the causes and consequences of MMEs remains. In the current thesis, I investigated the potential
causes of an acute MME of at-risk Blanding’s turtles (Emydoidea blandingii) at Misery Bay
Provincial Park on Manitoulin Island, Ontario in which approximately 50% of the population
succumbed to mortality, and used population viability analyses (PVAs) to examine strategies to
recover the population. Because the park includes relatively pristine habitat in which most of the regular anthropogenic threats to turtles are absent, the hypotheses I tested to explain the mortality
considered natural threats, including disease, failed overwintering, and predation in the winter
and active seasons. I determined that the most likely cause of death was a large-scale predation
event, which received support from several lines of evidence, including the presence of predators
within the park, a failed predation attempt on a live Blanding’s turtle, and the meticulous
destruction of a turtle decoy stationed where carcasses were found. The recovery strategies
examined included nest protection, introduction of juveniles, introduction of adults, and a nest
protection plus introduction of juvenile combination strategy. PVAs determined that the most effective recovery strategy for this population would be a combination of nest protection and the
annual introduction of 25 two-year-old females for a period of 50 years. The information gained
through my study has led to the recommendation of appropriate conservation strategies for this
population, and will aid in the management of future MMEs elsewhere.

subject:
Anishnaabe seven life stages model

Indigenous interventions

abstract:
Colonial violence, multi-generational trauma and systemic racism greatly contribute to
the high rate of Indigenous homelessness. This thesis focuses on the experiences of a formerly
homeless Indigenous man; his life history is analyzed through an approach informed by
teachings on the Anishnaabe seven life stages. The findings show how life events and
experiences contributed to homelessness and to recovery. Many years of chronic homelessness
came to an end with learning about cultural traditions and access to Elders. With additional
supports from some positive mainstream interventions, he overcame barriers and obtained secure
housing. The findings suggest the nature of the changes required to end poverty and
homelessness among Indigenous populations. This thesis speaks to Indigenous perspectives
about success and healthy communities. Organizations can be useful by supporting and assisting
Indigenous communities to provide services based on homegrown solutions. Investing in the idea
of a healthy community, healthy Elders and healthy families can help to break cycles of multigenerational
trauma, internalized oppression, abuse and poverty. Initiatives led by Indigenous
people such as Healthy Babies programs, schooling, health care, and child protection can support
healing and preserving the culture, but also can create employment, pride, and the opportunity to
give back in meaningful ways. Opportunities for communities to have access to healthy foods,
recreation and physical activities may also provide young people with positive experiences.
Places where youth can play safely and develop their skills are crucial during the Good Life and
Fast Life. The factors needed for an urban Aboriginal person to achieve bimaadiziwin include involvement with supportive/healthy cultural communities and opportunities to give back in meaningful ways; they can lead to traditional healing, a sense of belonging and personal identity.  Access to such supports should be ensured in childhood.

abstract:
Background: Non-pharmacological multicomponent interventions for the prevention of delirium
have been well studied in the acute care setting. Less is known however, regarding this approach
in long term care environment.
Aim: The purpose was to systematically synthesize evidence pertaining to non-pharmacological
nursing interventions for the prevention of delirium among older adults residing in long term
care settings.
 Methods: This study used a scoping review methodology guided by Arksey and O’Malley’s
(2005) framework. A total of eight academic databases were searched. In addition, reference
lists, clinical guidelines, and key journals were searched. To ascertain the nature of the extracted
data from reports meeting specific inclusion criteria, descriptive numerical data analysis methods
were used.
Findings: Results revealed a total of 13 reports; two clinical guidelines, one systematic review,
and 10 primary studies. The reviewed evidence examined single rather than multicomponent
interventions for the prevention of delirium in the population of interest. Collectively, the
heterogeneous and mixed findings addressed hydration, risk reduction and education of staff.
Conclusion: The results were stark in contrast to the established body of work regarding nonpharmacological
multicomponent approaches in acute care.

abstract:
The document presented herein is a manuscript-based thesis, entitled: Living with a Sibling who
has Autism Spectrum Disorder (ASD). This thesis consists of an exploratory investigation to
learn more about the experiences of individuals who have a sibling with ASD. The data obtained
is discussed in two papers. The first paper focuses on the discussion of future caregiving which
involves the transference of care to siblings (with typical development) when parents are no
longer able to provide care. The scope of the second paper solely focuses on data obtained from
interviews using Interpretative Phenomenological Analysis (IPA; Smith, Flowers & Larkin,
2009). Siblings highlighted particular aspects of future caregiving that harboured concerns,
resulting in the discussion of four relevant themes. The second paper was guided by the Family
Adjustment and Adaptation Response (FAAR) Model (Patterson, 1988, 1989; Patterson &
Garwick, 1994) to explore the type of stressors that were experienced and whether adequate
supports were being utilized. To understand experiences specific to demands and supports, a
mixed-methods approach was employed. Informed by the FAAR, interview transcripts were
analyzed using Thematic Analysis (Braun & Clarke, 2006), revealing four themes. Descriptive
statistics were also provided based on data obtained from two questionnaires: The Sibling
Inventory of Behaviour Scale (SIBS) and The Sibling Daily Hassles and Uplifts Scale (SDHUS).
Results concluded that siblings are constantly in the process of finding new resources and
developing new capabilities to manage demands across the life span. Clinical implications for
each paper are discussed further.

traumatismes, vécus dans l’enfance, qui ont des impacts sur l’apparition des maladies mentales à
l’âge adulte. La gravité croissante de ce phénomène, la pénurie des services de traitement
spécialisé et des ressources d’intervention précoce, d’appui et de prévention, mettent en évidence
la nécessité des solutions urgentes, au niveau personnel, familial, social et relationnel. Cette
problématique, peu explorée, par la littérature dominante, nous interpelle en raison des
observations personnelles et professionnelles que nous avons effectuées et des constats que nous
avons établis sur l'envergure sociale de ce phénomène peu pris en charge. Les résultats de cette
recherche contribueront alors au développement de nouvelles pistes de recherche, et à
l'implémentation des politiques de protection préventive de l’enfance et de la famille, en vue de
l’éradication progressive des formes d’abus qui mènent à l’éclosion des maladies mentales à
l’âge adulte. De ce fait, le renouvellement et le renforcement des stratégies d’intervention
psychosociale, structurelle et familiale en travail social et en santé mentale serviront à
l’amélioration des conditions de vie des victimes. Les perspectives, les propositions et les
recommandations les plus pertinentes, contribueront ainsi à l’apport de solutions viables, à la
prévention et au traitement des traumatismes d’enfance et de leurs impacts psychopathologiques

Somewhat Homomorphic Encryption
Secure Range query

abstract: With the development of the cloud computing, recently, many service models have appeared which are based on the cloud computing, such as infrastructure as a service (IaaS), platform as a service (PaaS), software as a service (SaaS), and database as a service (DaaS). For DaaS, there exist many security issues. Especially, the database as a service cannot be fully secured because of some security problems. This research area of cloud computing is called as cloud security. One of the problems is that it is difficult to execute queries on encrypted data in cloud database without any information leakage. This thesis proposes a secure range query process which is based on a somewhat homomorphic encryption scheme to improve secure database functionalities. There is no sensitive information leakage in the secure range query process. The data that are stored in the cloud database are the integers which are encrypted with their binary forms by bits. A homomorphic “greater-than” algorithm is used in the process to compare two integers. Efficiency, security, and the maximum noise that can be controlled in the process are covered in the security and efficiency analysis. Parameter setting analysis of the process will also be discussed. Results of the proposed method have been analyzed through some experiments to test the secure range query process for its practicability with some relatively practical parameter settings.

abstract:
The footwall environment of the Sudbury Igneous Complex (SIC) host high-grade Cu-(Ni)-PGE
deposits that have become a prime exploration target due to increases in metal prices and
depletion of traditionally mined contact-style deposits that are high-grade Ni-Cu rich deposits.
Understanding and constraining footwall deposits has been underway for some time, still, several
aspects of these deposits that need to be constrained. With respect to alteration the nature, origin,
relevance, and significance of these hydrothermal minerals have not yet been constrained.
A detailed study of the homogeneous grey gabbro unit that is hosted in the Podolsky
2000 deposit host’s sharp-walled sulfide veins, rich in copper and PGEs was an ideal study area
to look at alteration leading up to sharp-walled sulfide veins and its association to mineralization
as the vein is approached. The initial step is to define and understand what the composition of the
least altered grey gabbro with respect to its petrogenetic, spatial, and chronological relationship.
Once the least altered grey gabbro is characterized alteration associated to these veins can be
explored in detail. Alteration assemblages associated to these sharp-walled veins could
potentially be implemented into an exploration tool for mining companies local to the area in
search of such footwall deposits. The least altered grey gabbro unit was not as homogenous as previously thought, after
careful review of petrography, SEM-DES, geochemical bulk-rock data, isotope work, and U-Pb
age dating; a suitable petrographic summary of the grey gabbro was achieved. Once a least
altered summary was achieved, comparing this data to transects leading up to these sharp-walled
sulfide veins and various samples of most altered grey gabbro were petrographically,
geochemically, isotopically, compared to the least altered samples available. Generally, understanding footwall deposits and unravelling the relevance and
significance of these hydrothermal minerals was summarized in this thesis, unfortunately, these
alteration trends are rather small and can only be observed <30 cm away from the vein, and are
most obvious against the vein. This indicated that alteration signatures are not very strong
outside of these sharp-walled sulfide veins, despite these veins ~1 m thick.

De toutes les activités éducatives, elle est rapportée comme étant la préférée des enfants et des données empiriques soutiennent son rôle dans le développement des habiletés subséquentes en lecture. L’objectif de la présente étude est d’examiner l’effet de la manipulation de la vitesse de présentation de la narration et de la difficulté des livres sur l’attention portée au texte et la compréhension du discours chez les enfants préscolaires. Quatre livres (deux livres faciles et deux livres difficiles) sont présentés à 11 enfants âgés entre 34 et 71 mois alors que leurs mouvements oculaires sont enregistrés, ainsi un questionnaire portant sur la compréhension du discours est administré après la présentation de chaque livre. Les résultats révèlent que les enfants passent significativement plus de temps sur le texte d’un livre facile lorsqu’il est présenté à vitesse lente. Il n’y avait aucun effet entre la présentation de narration et la compréhension du discours chez les enfants préscolaires.

abstract:
Ranking and prioritization are important endeavors that take place in a multitude of industrial,
commercial and professional domains. The Delphi method is a systematic procedure for
aggregating experts’ opinions, particularly those that are predicated on qualitative or otherwise
judgmental information. The method of pairwise comparisons provides an elegant means by
which the qualities of criteria or alternatives can be compared, ranked, quantized and provides
methods for the identification and resolution of inconsistencies. This thesis examines and proposes
a means by which the two methods can be combined, in order to provide an easy to
use system (which is then implemented as a reference implementation) for ranking and prioritization
of a number of alternatives that is broadly applicable to any number of ranking and
prioritization problems.

subject:
CryoVent
liquefied gases
gas liquefaction system
wind speed data synthesis
hydraulic wind turbine

abstract:
This research work, named as ‘CryoVent’, was focused on determining the feasibility of using
wind energy, to produce liquefied gases (cryogens) continuously in a safe approach that can be
used for the cooling and ventilation of underground mines. The experimental work performed
suggested that the continuous production of liquefied gases with variable input work is practical.
The average specific power consumption for liquefaction of nitrogen in this work was 7.86
kWh/kg using the refrigeration produced by helium. This is ~20 times higher than that consumed
by industrial scale gas liquefaction systems, but is practical for a small scale system. This
specific power consumption could probably be lowered if the working fluid itself is liquefied.
Analysis on wind speed variability and wind speed data synthesis were also performed
which suggested presence of multi-fractal nature in wind speed data that represent the temporal
variation. A new method developed to generate high sampling frequency wind speed data from available low sampling frequency wind speed data can have contribution in all sectors when
there is a need of higher sampling frequency time series data for simulation/study purposes.
The liquid nitrogen mass flow rate (kg/s) increased with increase in compressor motor
frequency and also when operating at variable motor input frequency. However, the average
compressor power consumption also increased compared to average power consumption
during operation at standard motor frequency of 60 Hz. This was in a laboratory scale
liquefaction system and needs to be tested in the large scale system experimentally. With 1 kg/s
of liquefied nitrogen supplied, ~459 kWr of cooling power is available to cool the deep mine air
which is at 30-400C. A volumetric flow rate of 0.062 m3/s of liquefied air can provide a cooling
power equivalent to that provided by a volumetric flow rate of 4000 m3/s of atmospheric air,
which is the requirement of some of the biggest mines in the world. The hydraulic wind turbine as proposed in this work can eliminate the system start-up
issues following the calm period, which are typical concerns with the wind energy integrations.
This research work has provided the required modeling and simulation results that are crucial in
development of the full scale ‘CryoVent’.

résistance au nickel chez les plantes de Q. rubra exposées à plusieurs doses de nickel et 3) de
déterminer l’expression des gènes impliqués dans la résistance au nickel chez les populations de
Q. rubra provenant de sites contaminés avec des métaux et de sites références de la Région du
Grand Sudbury (RGS). Plusieurs gènes associés à la résistance au Ni dans des plantes modèles et
non modèles ont été ciblés dans cette étude. Le PCR en temps réel (RT-qPCR) a été réalisé
suivant le protocole du fabricant. Nous n’avons observé aucun dommage ni de ralentissement de
croissance causés par le nickel sur les plantes qui ont été traitées avec différentes doses de nitrate
de nickel. L’expression des gènes Sérine AcétylTransférase (SAT) et Nicotianamine Synthase (NAS 3) ont été induites par le nickel dans les feuilles des plantes traitées avec 1600 mg/kg
comparées aux doses de 150 mg/kg et 800 mg/kg et les contrôles. Par contre, l’expression de
l’acide 1-aminocyclopropane-1-carboxylique désaminase (ACC désaminase) dans les feuilles a
été induite par le nitrate plutôt que le Ni lorsque les plantes étaient traitées avec 800 mg/kg
comparé aux témoins et autres doses. Aucune association n’a été établie entre l’expression de
NAS 3, SAT, ACC désaminase, Glutathion Réductase (GR), la protéine macrophage associé à la
résistance naturelle (NRAMP 3), la famille des protéines de transport à haute affinité
(AT2G16800) et la contamination par les métaux dans les populations naturelles de Q. rubra
dans la RGS. Ceci suggère que la quantité de métaux biodisponibles dans le sol n’est pas assez
suffisante pour affecter l’expression des gènes.

title: Geological characterisation guided by fuzzy k-means clustering of physical properties measured from core samples from the Victoria property, Sudbury Ontario

subject:
Fuzzy k-means algorithm
Confusion index
Physical property

abstract:
Core logging is a subjective practice done by geologists, which documents the mineralogy,
textures, alteration, mineralisation and other features to give core a rock name. Pattern
recognition techniques are able to characterise the rocks and link the geophysical and geological
data quantitatively. The fuzzy-k means algorithm is an unsupervised pattern recognition
technique, which groups data into clusters based on properties measured. This study will use the
fuzzy-k means algorithm to characterise core samples from 2 drillholes from the Victoria
property in Sudbury with thin section examination to identify how mineralogical changes can
affect the measurements. Four different physical properties (density, gamma ray, conductivity
and magnetic susceptibility) were measured from a total of 203 core samples of quartz diorite,
metagabbro, metabasalt, pyroxenite, olivine diabase and metasedimentary rocks. The samples
were classified into 4 different physical units, with additional confusion index values that
indicate how well the data was classified. Quartz diorite, metagabbro and metabasalt have the
highest confusion index values while the olivine diabase and metasedimentary rocks have the
lowest confusion index values. Combining the fuzzy k- means results and thin section
examination proved to be successful because heterogeneities in sulphide minerals, ore
mineralisation and variation in rock forming minerals cause an overlap in physical properties
with other rock samples, increasing the confusion index while homogeneity in mineralogy results
in a low confusion index.

title: Modeling of plasma dynamics during pulsed electron beam ablation of graphite.

subject:
Plasma dynamics
Pulsed electron beam ablation (PEBA)
Pulsed electron beam film deposition
Material heating
Target ablation
Plasma plume expansion
Graphite target
One-dimensional heat conduction model
Film growth

abstract:
Recent advances in the field of plasma nanofabrication suggest that plasma-based technologies
may replace many of the conventional chemical and thermal routes in the synthesis of
nanomaterials (with at least one dimension below 100 nm) and thin films. In contrast to the
conventional processing routes, where only neutral species are involved, a plasma is made up of
energetic species including ions, electrons, and excited molecules in addition to neutrals. Due to
the highly energetic nature of interactions among these species and with other surfaces (substrates),
a plasma allows for the formation of materials at higher rates even though their concentrations
might be low as compared with those of neutral species in non-plasma based methods. While the
mechanisms of the various interactions in a plasma are undoubtedly complex and require a
fundamental understanding, they offer new opportunities for material nanofabrication. Pulsed electron beam ablation (PEBA) has recently emerged as a novel and promising technique
for high quality thin films growth. Pulsed electron beam film deposition consists of many physical
processes including target material heating, target ablation, plasma plume expansion, and film
growth on a substrate. Electron beam ablation is a complex process, which comprises heating,
phase change, and removal of a fine fraction from the target surface. Ablation strongly affects the
space distribution, composition, mass transfer processes, which in turn has a critical bearing on
the structure, stoichiometry and properties of thin films. Plasma plume expansion into an ambient
gas is a fundamental issue in PEBA as the quality of thin films deposited onto the substrate depends
on the composition, energy and density of particles ejected from the target. A one-dimensional heat conduction model is presented to investigate the heating and ablation of a
graphite target upon interaction with a polyenergetic electron beam. The effect of electron beam efficiency, power density, accelerating voltage, and Knudsen layer just above the target surface
during ablation are taken into account in the model. Phase transition induced during ablation is
considered through the temperature dependent thermodynamic properties of graphite. The
temperature distribution, surface receding velocity, melting depth, ablation depth, and ablated
mass per unit area are numerically simulated. Upon ablation, plasma expansion, induced by
interaction of a nanosecond electron beam pulse (~100 ns) with a graphite target in an argon
atmosphere at reduced pressure, was investigated by solving gas-dynamics equations. The spatiotemporal
profiles of the temperature, pressure, velocity, and density of the plasma plume are
numerically simulated for a beam efficiency of 0.6 and accelerating voltage of 15 kV. Each model
is validated by comparing some of the obtained simulation results with experimental data available
in the literature.

abstract:
Transdiagnostic interventions may be a beneficial approach for reducing a number of mental
health concerns. As such, the current study replicated and extended on a 10-week online
intervention for perfectionism to reduce perfectionism, depressive and anxious symptomology,
and negative affect using three groups: cognitive behaviour therapy (CBT), general stress
management (GSM), and no treatment (NT) waitlist. Moreover, a process and outcome approach
was used to monitor weekly changes in psychological functioning, while considering the role of
treatment readiness. At posttest, the CBT group exhibited greater adaptive changes in depressive
and anxious symptomology, and negative affect than the GSM and NT groups. Although the
CBT group exhibited declines on cognitively-focused perfectionism indicators and some traitlike perfectionism indicators, the GSM group exhibited more adaptive changes on most
perfectionism indicators. Treatment adherence and treatment readiness are discussed as possible
contributors to treatment outcomes and attrition.

title: Aboriginal perspectives understanding and comparing the lived experiences and resilience of aboriginal men and women attending higher education

subject:
Aboriginal Peoples
colonialism
education
intergenerational cycles of trauma

abstract: Through an in-depth examination and review of the traumatic impact of colonialism and oppression faced by Aboriginal peoples, trends being to appear within the literature. These trends include the intergenerational cycles that foster negative outcomes for Aboriginal Peoples, specifically for those who were forced to endure the physical, emotional, mental, spiritual and sexual abuse within the Residential school system. The survivors of this era experience lifelong trauma which is then passed on through the generations to their children, grand-children, great grand-children etc. The numbers of Aboriginal students attending University level, higher education are increasingly low and the research has indicated that this is, in large part, due to the impact of the residential school system and the outlook that Aboriginal Peoples now have towards the education system. Factors of resiliency both positive and negative are described throughout. Positive resiliency, from a western perspective, include the ability to overcome adversity (Scarpino, 2007). This research project utilizes a qualitative method of open-ended one-on-one interviews with Aboriginal men and women who are students at Laurentian University in order to better understand their lived experiences and the aspects that have fostered positive resiliency for them to pursue higher education.

subject:
Microarthropods
Collembola
Oribatida
metabarcoding
DNA barcoding
richness estimate
spatial autocorrelation
integrated taxonomy

abstract:
Soil microarthropods are ubiquitous and ecologically significant in terrestrial environments.
Collembola and Oribatida are the two most abundant and diverse representatives of
microarthropods and are commonly targeted biological indicators of soil quality. Traditional
methods for studying these groups have provided taxonomic and functional data for individuals
but are inefficient for large scale biomonitoring applications. The adoption of molecular methods
like metabarcoding is predicted to improve the efficiency of biomonitoring microarthropods but
can be limited by the availability of reference specimens in sequence databases, and the
importance of barcode selection and sampling design for this approach in plot-level experiments
has not been explored. Demonstrated here, the inclusion of locally derived specimen barcodes to
reference libraries significantly improved the quality of metabarcoding data. Also, targeting two
barcodes (18S and COI) improved microarthropod richness estimates, and 10 samples with >10
m separation between each is recommend to increase the proportion of diversity detected.

subject:
red maple (Acer rubrum)

abstract:
he main objectives of the present study were to 1) compare the physiological responses and
gene expression in red maple (Acer rubrum) and trembling aspen (Populus tremuloides) exposed
to metal contamination, 2) determine if epigenetic events are associated with metal resistance in
A. rubrum, and 3) assess global gene expression in A. rubrum exposed to different doses of nickel.
Metal analyses of soil and plant tissues revealed that P. tremuloides is an accumulator of Mg, Zn,
and Ni while A. rubrum does not accumulate these metals in the leaves as it shows avoidance as
the main mechanism of coping with soil metal accumulation. Comparative analysis of gene
expression revealed that the four genes tested (Nramps4, Nas3, At2G, and MRP4) were more
upregulated in P. tremuloides compared to A. rubrum in a field study. AT2G and MRP4 genes
were significantly down regulated in A. rubrum from the targeted metal contaminated sites
compared to those from uncontaminated areas but environmental factors driving this differential
gene expression couldn’t be established. The growth chamber experiment, showed differential
gene expression based on p values when the effects of nickel doses were compared. There were
more upregulated than down regulated genes in resistant genotypes compared to susceptible
genotypes. Most of these genes are associated with coping with abiotic stressors and involves
tolerance and detoxification mechanisms. There was a significant variation in the level of cytosine
methylation among the metal-contaminated sites, with significant negative correlations between
bioavailable nickel / copper content and cytosine methylation being observed.
In Conclusion, the present study reveals that A. rubrum exhibits the avoidance strategy as the
main mechanism of coping with soil metal accumulation. However, a more informative and indepth analysis of this mechanism would be very beneficial in deciding whether it is strictly
physiological or genetic. The role of epigenetics can be further understood by determining the
distribution of DNA methylation in both A. rubrum and P. tremuloides.

subject:
Structural geology
intrusion-related gold deposit

sheeted veins

abstract: The Archean Côté Gold deposit (8.3 M oz) is a low-grade, high-tonnage Au(-Cu) deposit located within the 2741 Ma Chester Intrusive Complex (CIC) on the southeast limb of the Swayze Greenstone Belt (SGB) in the Abitibi Subprovince of northern Ontario. Steeply-dipping, auriferous sheeted veins that form part of the mineralized setting can be interpreted as either orogenic in origin and associated with the formation of the proximal Ridout deformation zone or as older and intrusion-related. Structures that overprint CIC are similar to those of the RDZ and are interpreted to post-date the intrusion and mineralized veins. A geochemical study of an alteration profile related to a mineralized vein reveals elemental enrichment in K, Rb, Li, Cs, Ba, Na, F, S and LREEs with a Au-Cu-Te-Pb-Bi-S association. In situ SIMS analysis of δ34S and δ18O are consistent with a magmatic signature for the fluid with a minor component of seawater, and supports the previously proposed high-level, subaqueous setting for the deposit. The combination of temporal, spatial, and geochemical characteristics of the sheeted veins suggests an intrusion-related origin.

This research looks at the social construction of anorexia and bulimia nervosa. A discourse and content analysis of pro-anorexia and pro-bulimia websites was conducted to determine whether or not this sub-culture and group of individuals fulfilled the criteria of a social movement. Findings found that individuals living a pro-ana and pro-mia lifestyle choice demonstrated various forms of resistance against the discourses and practices defining anorexia and bulimia as illnesses. With the information gathered in relation to the theoretical approach to social movements, pro-ana culture seems to fulfill
the dimensions to be considered a proto social movement.

abstract:
Microorganisms inhabiting the gastrointestinal tract of vertebrates co-exist with their hosts
and may provide them with health and physiological benefits. However, environment-microbehost
interactions within gut microbiome communities (GMCs) are poorly understood. In this study
deer mice (Peromyscus maniculatus) were used to determine a) how the natural (wild)
environment influences GMCs compared to captivity and b) how microbes associated with the
natural environment as well as overall GMC α-diversity influences host immunocompetence.
Captive- and wild-born deer mice were sampled twice (initial and post-translocation phases), twoweeks
apart. After the initial sampling period a sub-sample of deer mice were reciprocally
translocated between environments to assess how the external environment influences host GMCs
and immunocompetence. Non-translocated individuals served as captive- and wild-born controls.
GMCs were analysed via fecal samples, sequenced using 16S rRNA next –generation Illumina
HiSeq sequencing. Host immunocompetence was determined using blood cell counts and a
functional immune challenge (i.e. bacteria killing assay). Captive individuals possessed less
diverse GMCs compared to wild individuals. Individuals translocated from captivity to the wild
increase in GMC α-diversity, while individuals reciprocally translocated experienced a decrease.
Individual’s GMCs clustered closer together with deer mice sharing the same environment. In
natural environments deer mice had higher abundances of Ruminococcaceae, Helicobacteraceae,
and Lachnospiraceae spp., than in captivity. No strong correlations were found between GMC α-
diversity and host immunocompetence. Findings suggest that despite containing less diverse
GMCs in captivity, upon reintroduction to natural environments deer mice GMCs rapidly changed,
homogenizing with deer mice in the same environment. Future experiments should further study
the effects of reduced exposure to Ruminococcaceae, Helicobacteraceae, and Lachnospiraceae
during early-life stages, to better understand environment-microbe-host interactions.

subject: incremental assignment problem

subject: improved incremental assignment algorithm

subject: group role assignment

abstract:
The Assignment Problem is a basic combinatorial optimization problem. In a weighted
bipartite graph, the Assignment Problem is to find a largest sum of weights matching. The
Hungarian method is a well-known algorithm which is combinatorial optimization.
Adding a new row and a new column to a weighted bipartite graph is called the
Incremental Assignment Problem (IAP). The maximum weighted matching (the optimal solution)
of the weighted bipartite graph has been given. The algorithm of the Incremental Assignment
Problem utilizes the given optimal solution (the maximum weighted matching) and the dual
variables to solve the matrix after extended bipartite graph.
This thesis proposes an improvement of the Incremental Assignment Algorithm (IAA),
named the Improved Incremental Assignment Algorithm. The improved algorithm will save the
operation time and operation space to find the optimal solution (the maximum weighted
matching) of the bipartite graph.
We also present the definition of the Incremental Group Role Assignment Problem that
based on the Group Role Assignment Problem (GRAP) and Incremental Assignment Problem
(IAP). A solution has been designed to solve it by using the Improved Incremental Assignment
Algorithm (IIAA).
In this thesis, simulation results are presented. We utilize the tests to compare the
algorithm of the Incremental Assignment Problem and the Improved Incremental Assignment
Algorithm (IIAA) to show the advantages of IIAA.


title: Exploration des perceptions des intervenants en santé mentale, en contexte de recherche de services pour eux-même: étude chez les francophones des régions de Sudbury, de Nipissing ouest et de North Bay

subject:

abstract:
Ce mémoire vise à explorer la perception de diverses formes de stigmatisation ressenties par certains intervenants en santé mentale en quête de services pour eux-mêmes. La théorie de la stigmatisation de Goffman (1963) et la théorie des systèmes (von Bertalanffy, 1956) seront utilisées pour examiner ce phénomène.
Cette étude comporte trois objectifs. Premièrement, elle vise à comprendre comment les intervenants vivent leurs propres besoins de services en santé mentale dans la réalité du milieu. De plus, cette étude a voulu explorer l’existence de tabous vis-à-vis la santé mentale dans la société contemporaine. Enfin, elle souhaite sensibiliser la population envers les défis d’accessibilité à des services de santé mentale en français dans les régions désignées.
Cinq thèmes provenant des entrevues seront définis et expliqués : les services d’aide en santé mentale, les différentes perceptions de la santé, la perception des stigmas entourant les problèmes mentaux, le contexte de la communauté franco-ontarienne en situation minoritaire et le statut d’intervenant en santé mentale dans son rôle comme aidant dans la société.
Des entrevues qualitatives ont été effectuées auprès de huit intervenants francophones en santé mentale, évoluant en milieu minoritaire dans les centres urbains de Sudbury, de Nipissing Ouest et de North Bay. Les données recueillies lors d’une entrevue avec les participants ont dégagé leurs perceptions de la santé mentale en général, de leur entourage et leur communauté. Aussi, leur appréciation des services de santé mentale publics disponibles en français dans les régions ciblées fut explorée.

subject:

multiple case study

abstract:
A multiple case study was undertaken with five Nurse Practitioner-Led Clinics (NPLCs) in in the
North East and North Muskoka Simcoe Local Health Integration Networks in Ontario, Canada.
The purpose was to evaluate the quality of care in NPLCs, specifically to address the following
research questions: What is the relationship between organizational processes in the NPLC
model and the care of diabetic patients with multimorbidity? To what extent are clinical practice
guideline indicators for diabetes care being met for patients with multimorbidity in five NPLCs?
How do nurse practitioners practicing at NPLCs evaluate the impact of the NPLC model on the
quality of the care they provide to diabetic patients with multimorbidity? The research was
guided by the Donabedian Quality Framework.
The study included three types of data collection. First, documents related to NPLCs were
collected and the impact of the nurse practitioner (NP) as primary care provider was analyzed.
Then the Chronic Care Model was used to guide the development of a chart audit in each of the
five NPLCs, conducted on 30 charts per clinic (n= 150) for non-pregnant, adult diabetic patients
with multimorbidity. Analysis determined relationships between diabetes indicator scores and
organizational and patient data. Next, 8 NPs from 4 of the 5 NPLCs participated in interviews,
guided by semi-structured questions arising from the document review and chart audit analysis.
Interpretive description methods were used to analyze the transcripts and identify themes.
A cross-case analysis was conducted to compare the results of all analyses across NPLCs.
Themes emerging from this multiple case analysis confirmed that the NP is the primary care
provider and clinical leader at NPLCs, which has contributed positively to the quality of care in
NPLCs. NPLCs have suffered from poor NP recruitment and retention. This, along with
insufficient health care resources in the communities where NPLCs are located and high patient
vulnerability, has had a negative influence on the quality of care. Strategies including mentoring
and changes to funding offer possible solutions to improve the quality of care at NPLCs. (336

title: Exploring the impact of kindergarten scheduling on children's physical activity and classroom behaviour.

subject:
Children
Early Learning Kindergarten
Physical Activity
Classroom Behaviour

abstract:
The Ontario Ministry of Education implemented the new Early Learning Kindergarten (ELK) program province-wide in September 2014. The ELK program advocates for inquiry- and play-based learning, and the use of the outdoors. Some school boards have implemented a 60-minute outdoor exploration block replacing outdoor recess breaks. These changes have not been
evaluated for their potential impact on both the physical activity levels and classroom behaviour of children while at school. This thesis investigated physical activity levels and classroom behaviour of children in the new ELK schedule, and in the Balanced School Day (BSD) schedule. The results suggest that children following the ELK program exhibit reduced physical activity levels, but greater academic engagement and less disruptive behaviour. Thus, results suggest that the ELK program provides benefits for students, but modifications are needed to
ensure that adequate physical activity is introduced in early-year programming therefore providing a strong foundation for both education and physical activity.

Beardmore-Geraldton greenstone belt

abstract:
The Beardmore-Geraldton belt (BGB) is a greenstone belt straddling the boundary between the
eastern Wabigoon subprovince and the Quetico metasedimentary subprovince. It consists of shearbounded panels of metavolcanic and metasedimentary rocks which were imbricated during an
early thrusting event and regionally folded and sheared during subsequent deformation events. It
hosts several historic gold mines with a combined past production exceeding 4 Moz gold. New
gold resources were delineated within the last ca. 10 years at the Hardrock deposit in the eastern
part of the belt which highlighted the need for a better understanding of the controls on gold
mineralization in the belt.
The BGB comprises three panels of metasedimentary rocks, representing a southward transition
from fluvial to deltaic to deep oceanic basin plain environments, overlying three panels of older,
ca. 2725 Ma, metavolcanic rocks, representing back arc, island arc, and oceanic crust. Detrital
zircon geochronology of the BGB and adjacent northern Quetico metasedimentary rocks suggests
that these rocks formed from sediments derived by the erosion of ca. 2700 Ma to 2900 Ma source
rocks and older >3200 Ma Mesoarchean craton of the eastern Wabigoon subprovince. The
emplacement of crosscutting 2694±1 Ma feldspar-quartz porphyry (FQP) dikes, marks the end of
sedimentation in the belt. The panels were subsequently imbricated during an early thrusting event
(D1) which ended with the emplacement of the stitching 2690±1 Ma Croll Lake stock. The
composition of the FQP dikes and Croll Lake stock (i.e. SiO2, ferromagnesian oxide and transition
element contents, [La/Yb]N ratio) indicate a shift from tonalite-trondhjemite-granodiorite (TTG)
suite to sanukitoid suite magmatism over a 4 Ma period. The formation of the sanukitoid melts,
which involves the addition of a mantle melt component, is consistent with their generation during
delamination or slab break-off as the BGB metavolcanic and metasedimentary panels were thrustimbricated and accreted to the Wabigoon subprovince during closure of the Quetico basin.
D1 structures are expressed by early, isoclinal, F1 folds with an axial planar S1 cleavage. They are
folded by regional F2 folds with an axial planar, regional, S2 cleavage, which becomes more
pronounced along belt-parallel, sinistral, high strain zones characterized by asymmetrical, Sshaped F2 folds and NE-striking, en echelon, quartz-carbonate veins. The association of regional
folds and cleavage with sinistral high strain zones suggest that these structures formed during
regional sinistral transpression (D2) across the belt. During subsequent dextral D3 transpression,
the regional F2 folds and S2 cleavage were overprinted by Z-shaped F3 folds and by a second
regional cleavage (S3), and the D2 high-strain zones were reactivated as dextral shear zones. Within
the reactivated high strain zones, F1, F2 and F3 fold axes are parallel to a strong, shallowlyplunging, stretching lineation that formed during D2 and was accentuated and rotated towards the
orientation of the fabric attractor during D3. The fabric attractor is oblique to the intersection
lineation between the reactivated S2 cleavage and dextral shear bands, suggesting that the
deformation during D3 had triclinic symmetry.
The Hardrock gold deposit is one of several deposits hosted by the Bankfield-Tombill deformation
zone near Geraldton in the eastern part of the BGB. Gold was emplaced during early D1 thrusting
and D2 sinistral transpression in association with strongly folded, early D1, quartz-carbonate veins
(V1) and E- to NE-striking, syn-D2, tourmaline-rich (V2) and quartz-carbonate veins (V3) veins.
Gold is present in association with inclusion-rich pyrite with elevated Au, Ag, As, Bi, Co, Ni, Pb,
Sb, Te concentrations and along fractures and as inclusions in the veins and sulfides. The deposit
is surrounded by a broad (≤250 m) alteration envelope of carbonate and sericite with elevated
pathfinder S, Te, As, W, and Bi concentrations. Early introduction of gold in the belt during
thrusting and sinistral transpression differs from previous studies which favored late tectonic
emplacement of gold in D3 shear zones and fold hinges.

SNO+ experiment
Laserball simulation
Low radon permeable gloves

Calibration sources

abstract:
The SNO+ experiment is a multipurpose liquid scintillator detector whose  rst goal is to
measure neutrinoless double beta decay. This thesis describes two important components:
simulations to optimize the time window for the prompt peak of an optical calibration
source, the \laserball" and the search for gloves to handle calibration sources while maintaining
stringent background conditions.
Non-direct light found in laserball runs creates challenges for optical calibration. By
changing the time pro le from the standard  4ns to an asymmetric pro le of +2
􀀀4 ns this
contribution of non-direct light can be reduced up to 45%.
Gloves provide an access point to manipulate calibration sources during deployment
inside the detector and as barrier to 222Rn, a known background to the experiment. However,
typical glove materials are found to permeate large amounts radon. Through a careful
selection process the material Silver Shield was chosen for use in SNO+ with a permeation
rate of 1:1   10􀀀6 radon atoms/hour.

abstract:
This thesis presents the design, construction and testing of a boundary layer turbine, also known
as a Tesla Turbine. A turbine, with discs of 92mm in diameter, central exhaust, plenum
chamber, and swappable nozzles was constructed. The setup included instrumentation and a
simple torque sensor with which to sense the relatively low torques given the low testing
pressures. After construction, the setup was tested with various angles of nozzles ranging from
2.5° to 45° from tangential. The testing resulted in an estimated maximum efficiency of 8.5%,
while running the rig at 3 bar, which is comparable to the literature. Unexpectedly, this
maximum was achieved with a nozzle pointed at 45° from tangential, which may have been
caused by the disc pack variant used in the tests.

subject:

isothermal compression
air absorption

abstract: A hydraulic air compressor (HAC) is a no moving parts compressor that uses hydropower to compress air that is inducted through a Venturi effect. The solubility of gases in water increases with pressure and provides a means for the dissolved gas to bypass the air-water separator and reduce the compressed air yield of a HAC. The model developed and fully described herein extends the approach of Chen and Rice (1983) to allow for a multiplicity of gas mixtures, predicts the compressed air yield reduction from gas solubility, and predicts the compressed air yield improvement by increasing the liquid temperature and the presence of pre-dissolved salts. The model simulated multiple scenarios that adjust the parameters that are known to affect air absorption in the downcomer and returns results consistent with the expected behaviour in each scenario. One of such scenarios was the simulation of the downcomer of the Ragged Chutes HAC installation. The results were compared with the single data point of oxygen concentration in compressed air delivered by a HAC and results from an equilibrium solubility model available in the literature. Under the same conditions, the model described herein predicts a concentration of oxygen of 0.181 mol/mol, a value that is 2.3% higher than the equilibrium condition. In order to match the results of the equilibrium model, the mass diffusivities of nitrogen, oxygen, argon and carbon dioxide needed to be artificially increased from their reported values in the literature by a factor of 2000. This suggests that the solubility kinetics are important to consider in the design of a HAC when predicting the compressed air yield but if the equilibrium assumption is adopted the estimate of compressed air yield will be conservative.

(Semi Structured Data) in different languages and terms, which contains noise in data as
well as critical information that encourage the analyst to discover knowledge and pattern
from the dataset available. This is useful for decision making and taking strategic decision
for the future market.  To discover this unknown information from the linguistic data Natural Language
Processing (NLP) and Data Mining techniques are most focused research terms used for
sentiment analysis. In the derived approach the analysis on Twitter data to detect sentiment
of the people throughout the world using machine learning techniques. Here the data set
available for research is from Twitter for world cup Soccer 2014, held in Brazil. During
this period, many people had given their opinion, emotion and attitude about the game,
promotion, players. By filtering and analyzing the data using natural language processing
techniques, and sentiment polarity has been calculated based on the emotion word detected
in the user tweets. The data set is normalized to be used by machine learning algorithm and
prepared using natural language processing techniques like Word Tokenization, Stemming
and lemmatization, POS (Part of speech) Tagger, NER (Name Entity recognition) and
parser to extract emotions for the textual data from each tweet. This approach is implemented using Python programming language and Natural Language Toolkit (NLTK),
which is openly available for academic as well as for research purpose. Derived algorithm
extracts emotional words using WordNet with its POS (Part-of-Speech) for the word in a
sentence that has a meaning in current context, and is assigned sentiment polarity using
‘SentWordNet’ Dictionary or using lexicon based method. The resultant polarity assigned
is further analyzed using Naïve Bayes and SVM (support vector Machine) machine
learning algorithm and visualized data on WEKA platform. Finally, the goal is to compare
both the results of implementation and prove the best approach for sentiment analysis on
social media for semi structured data.

Abstract
Passionate activities can be a source of pleasure and meaning. According to the Dualistic Model
of Passion (Vallerand et al., 2003) individuals can have either a harmonious or an obsessive
passion for an activity. Where harmonious passions provide positive emotional experience,
obsessive passions do not. Using Fredrickson’s broaden-and-build theory (2004), it was
hypothesized that harmonious passions could have cognitive benefits. By grouping individuals
(N=141, M-age=24 years, 89 women) based on their passion orientation, the roles of selfreported
optimism, social desirability, social support, attention, executive functioning, and life
quality were examined in distinguishing harmonious and obsessive passion. It was demonstrated
that harmoniously passionate individuals differed from the obsessively passionate on all
measures of attention, executive functioning, and life quality. Where obsessively passionate
individuals reported lower attention, executive functioning, and life quality, harmoniously
passionate individuals did not. Individuals who were highly passionate differed from less
passionate people on optimism. These differences correspond well to that which would be
predicted on the basis of the broaden-and-build theory. Taxometric methods were also used to
investigate the latent structure of Vallerand’s Passion questionnaire. Taxometric methods can test
whether a construct is categorical (passion being harmonious or obsessive) or dimensional (only
varying in degrees of intensity). Results from taxometric analyses (MAMBAC/MAXCOV) are
most consistent with the idea that passion exists in a continuum between its harmonious and
obsessive forms.

abstract: As reptile populations worldwide decline, construction and monitoring of road mortality mitigation measures is becoming common. I studied the effectiveness of barrier fencing at preventing Eastern Massasauga rattlesnakes (Sistrurus catenatus) from gaining access to the road. I also tested whether ecopassages were effective at allowing Massasaugas to access habitat on both sides of the road. I determined that there was a reduction of Massasaugas on the road post-installation of barrier fencing. Data from various monitoring approaches showed that Massasaugas do indeed use the ecopassages to cross the road. I quantified the long-term effect of mitigation structures on the population viability of Massasaugas. A Population Viability Analysis revealed that post-mitigation construction, the study population has a low probability of extinction, suggesting that mitigation is effective at promoting a sustainable population. Analyzing the effects of road mortality at the population level is crucial to ensure that decision makers are adequately informed of the status of species-at-risk.

title: Multiple dietary supplement and protection against radiation-induced damage

subject:

multiple dietary supplement (MDS)

abstract:
Radiotherapy is a critical part of cancer treatment. With the recent medical advancements
and increased survival rate of cancer patients, there is also an increased risk of radiationrelated
tissue damage and toxicity which could lead to severe organ damage or even organ
failure. Medications that could be used as prophylaxis or treatment provide a better quality
of life for cancer patients. In the present study, we evaluated the radio-protective potential of
multiple dietary supplement (MDS) in an animal model by looking at the gene expression
levels of the renin-angiotensin system. In mice receiving 5 Gy radiation, MDS administration
as prophylaxis or treatment was able to decrease the expression levels of angiotensinogen
which suggested the lower activity of RAS in irradiated kidney tissue. This finding indicates
MDS potential for tissue radioprotection. Study of expression levels of kidney antioxidant
enzymes also suggested benefits of MDS in protecting kidney tissue from radiation-induced
reactive oxygen species evidenced by the lack of upregulation in expression levels of genes
such as GPX1, NOS3 and SOD2 in mice receiving MDS as prophylaxis. Also, systemic
effects of MDS to protect the body from radiation-induced physiological stress was studied
by evaluating genes involved in catecholamine biosynthesis pathway in adrenal. Data from
expression levels of phenylethanolamine N-methyltransferase (PNMT) suggests MDS
protected the animal from radiation-induced physiological stress. MDS was useful both for
prophylaxis and treatment. Further examination was also conducted to determine MDS
effects on radiation-induced antioxidant and DNA damage and repair response and also
changes in expression levels of DNA methyltransferases. Collectively our results suggested
MDS has the potential to protect the mice tissue from radiation induced tissue damage,
oxidative stress and physiological stress.

subject:

abstract:
This article-based thesis examined the effects of stress and attachment
style on eating. The first article explored the effects of stress on the eating
patterns of undergraduate students. Results demonstrated that stress leads
to reported unhealthy changes in eating habits. Specifically, stress led to
increased reported preference for take-out food options. Findings showed
that gender influenced stress-related snacking and loss of control over
eating. The second article examined the influences of stress and
attachment on eating in self-reported stress under-eaters and stress-eaters.
The results demonstrated that attachment style uniquely influences the
eating of these two distinct groups and that stress and attachment have
differential effects on eating. These findings add to the paucity of research
investigating the effects of stress on eating from a naturalistic approach.
These results also identify various idiosyncrasies of these two novel
groups and highlight the role of attachment in disordered eating behaviour.

title: Nanocomposites of carbon nanosphere and graphene oxide with iron oxide as high-performance adsorbents for arsenic removal

subject:

abstract:
Arsenic is a widely distributed element in the Earth’s crust with an average
terrestrial concentration of about 5 g ton-1
. Arsenic is a persistent, bio-accumulative, toxic
element. The United States Environmental Protection Agency (EPA) has implemented the
discharge criterion of 10 µg L
-1
for arsenic as the maximum acceptable level for ground
water. During the past decades, several techniques have been developed for the removal
of arsenic from the wastewater, including chemical precipitation, adsorption and ion
exchange, membrane and biological removal processes, and so on. Because of the good
arsenic removal efficiency and the low cost, adsorption is a more popular method. In this
thesis research, two ranges of iron oxide nanocomposite adsorbents have been developed
and studied for their performance properties towards arsenic removal.
Novel iron oxide encapsulated carbon nanospheres (FeOx-CNS) with excellent
arsenic adsorption performance has been successfully synthesized. CO2 activated carbon
nanospheres material (A-CNS) with high surface area (2271 m²g
-1
) and high pore volume
(5.18 cm³g
-1
) was selected as the porous matrix. After surface oxidation by ammonium
persulfate (APS), iron oxide was loaded into the carbon nanospheres as the effective
arsenic adsorbent. Transmission electron microscopy (TEM) and Braunauer–Emmett–
Teller (BET) results indicate that iron oxide nanoparticles (7-60 wt%) are well-dispersed
within the mesopores. In particular, FeOx-CNS-13 composite shows most optimum  performance properties, with high arsenic adsorption capacities achieved for both As(III)
(416 mg g−1
) and As(V) (201 mg g−1
).
Another range of amorphous iron oxide-graphene oxide (FeOx-GO)
nanocomposites having different graphene oxide (GO) content (36-80 wt%) was prepared
by coprecipitation of ferrous sulfate heptahydrate and ferric sulfate hydrate on GO sheets.
The composites have been thoroughly characterized and investigated for their
performance towards arsenic removal. The optimum composite, FeOx-GO-80 having the
highest iron oxide content of 80 wt% shows excellent arsenic adsorption capacities for
both As(III) (147 mg g−1
) and As(V) (113 mg g−1
), which are highest among iron oxideGO
composites reported to date for arsenic removal. The high performance along with
low cost and convenience in synthesis makes this range of amorphous iron oxide-GO
nanocomposites promising for applications.

abstract:
The abuse of amphetamine-related drugs (ARDs) is an epidemiological phenomenon in Saudi
Arabia. This drug abuse is found to play an important role in early mortality due to traffic
accidents, violence, and overdose. Therefore, control ARDs abuse is crucial. In forensic
toxicology, ARDs analysis is carried out to identify human actions, such as driving under the
influence of drugs, clarify the manner and cause of death, and elucidate drug use. This study has
yielded practical analytical assay to using whole blood (WB) as a biological matrix in ARDs
analysis by using ultra performance liquid chromatography in coupling with quadrupole time of
flight mass spectrometry (UPLC-qTOF-MS). Here, two different types of solid phase extraction
(SPE) were evaluated. Molecularly imprinted polymers (MIP-SPE) was found to deliver a highly
clean extract, however, ephedrine (EPH) interference was proved to leach from the polymer
matrix of the sorbent materials. Mixed mode cation exchange (MMSPE) was found ideal to
extract ARDs from WB matrices. The analytical method was developed and validated according
to the Scientific Working Group for Forensic Toxicology (SWGTOX) Standard Practices. The
validated method was found capable of quantitative analysis of methylphenethylamine (BMP)
and detection of one of its metabolites in WBs of rats exposed to BMP by peritoneal injections

subject: région d’Ottawa

abstract:
L’objectif de cette étude consiste à montrer les bienfaits des activités de socialisation au programme de jour du Centre de services Guigues (CSG) sur la santé des personnes âgées francophones ayant vécu l’isolement ou la solitude dans la région d’Ottawa. En effet, le CSG est un organisme à but non lucratif de la collectivité francophone de la région d’Ottawa. Sa mission consiste à garantir des services de soutien communautaires et des activités socio-récréatives en français, dans toute la région d’Ottawa, aux personnes âgées ainsi qu’aux adultes ayant une incapacité.
Pour répondre aux questions de recherche et pour vérifier les hypothèses qui étaient mises en avant, l’approche structurelle a servi de toile de fond à cette étude. Elle a permis de comprendre, d’analyser et d’interpréter les résultats obtenus lors des entrevues semi-dirigées avec huit aînés ayant volontairement accepté de parler d’eux et de leurs expériences comme participants aux activités de socialisation au programme de jour du CSG.
Étant donné que l’approche structurelle part de la thèse selon laquelle ce sont les structures et les institutions sociales qui sont la source primaire des problèmes sociaux des individus, cette étude montre que le problème d’isolement et de solitude sociale des aînés francophone en contexte minoritaire constitue un problème dont la cause est aussi structurelle.  Bien que le CSG organise professionnellement les activités de socialisation à son programme de jour, à la suite de cette recherche, il s’avère que la structure du CSG nécessite un agrandissement à la dimension de sa mission. Cet agrandissement ne peut se faire que si la société (ville d’Ottawa, gouvernement provincial de l’Ontario et gouvernement fédéral du Canada) accepte de porter une attention particulière au problème d’isolement social des aînés francophones en contexte minoritaire dans la région d’Ottawa.
En substance, la recherche a démontré que la participation sociale ou les activités de socialisation procurent des bénéfices notables sur la santé des personnes âgées. Il importe de vérifier, avec d’autres études, à quel point ces activités de socialisation peuvent être bénéfiques, aussi bien pour les aînés encore en bonne santé – au début de la retraite – que pour les personnes âgées déjà fragilisées par les effets néfastes de l’isolement et de la solitude sociale. Cela permettra de déterminer le moment opportun et convenable pour optimiser les bienfaits de la socialisation, en lien avec l’âge et l’état de santé des aînés.

title: The geochemical behavior of metalloids and their effect on the highly siderophile elements during the crystallization of a magmatic sulfide liquid in relation to the formation of Ni-Cu-PGE magmatic sulfide deposits

subject:
Platinum-group elements
PGE
highly siderophile elements
HSE

abstract:
The highly siderophile elements (HSE), which include Re, Au and the platinum-group elements (PGE: Ru, Rh, Pd, Os, Ir, Pt) are of scientific and economic interest because they are tracers of geological processes (e.g., planetary differentiation) or have industrial or investment value. In most ore deposits, HSE are usually mined as by-products of Ni-Cu mineralization, such as those of the Sudbury district (Canada). Although at high temperature HSE are expected to be in lattice of sulfides they are usually found as discrete phases or platinum-group minerals (PGM). Many of PGM have metalloids (As, Se, Sb, Te and Bi) as essential constituents but, despite this relationship, the role of metalloids on HSE mineralization is still unclear. This dissertation documents the results of three experimental studies undertaken to investigate the effect of metalloids on the geochemistry of HSE. The first study examined whether the metalloids can mobilize HSE in an anhydrous environment. The results show that metalloids do not transport the HSE but also that Au, Pd and Pt can be efficiently fractionated from the other HSE and transported away from a sulfide assemblage through a relatively low-porosity, low-permeability medium in absence of hydrothermal fluids. The second study investigated the solubility of metalloids in monosulfide solid solution (mss) and intermediate solid solution (iss), to asses the conditions required for the formation of immiscible metalloid liquids and their effect on HSE partitioning. The results show that the metalloids form two separate phases, one that is As-rich and strongly sequestered Pt from the sulfides and another that is Bi-Te rich and affected mostly Pd and Au. The results also show that the other HSE (Ru, Rh, Re, Os, Ir) are largely unaffected by the presence of metalloids. In addition the results show that mss can dissolve significant amounts of metalloids (hundreds of ppm) before metalloid
V
saturation can occur. The third study constrained the geochemical behavior of metalloids and HSE in a pyrite-bearing sulfide system. The results show that Co-Ni-rich and HSE bearing pyrite can form during cooling of a sulfide melt and also that the HSE partition roughly equally between mss and pyrite, whereas Pd that partitions preferentially into mss and Au partitions preferentially into iss. Moreover, pyrite showed compositional zonation of many elements similar to that documented in natural pyrite samples that are also Co-rich and HSE-bearing. Thus, identification of such pyrite in natural assemblages is consistent with a magmatic origin.

abstract:
Diabetes is a disease that is highly prevalent in Indigenous communities at rates that exceed the
general population by up to four times. This research will explore the efficacy of an obesity and
diabetes screening and prevention program for children and youth that was self-initiated in a
First Nations community. Eight staff employed at the health and wellness centre were
interviewed using semi structured interviews. It was found that the program experienced much
success over the years due in part to the use of incentives, culturally appropriate programming
and dedicated staff. The program’s growth over the years led staff to conclude that time and
human resources were major limitations to the program. This research highlights key areas that
should be addressed when implementing a program and provides valuable insight for other
communities wanting to implement a program like this.

title: The sleep behaviour and fatigue trends of wildland firefighters during non-fire and fire deployments

subject:
Wildland firefighter
Fatigue
Sleep
Actigraphy
Injury-risk

abstract:
Ontario wildland firefighting is a hazardous and safety-critical operation with relatively high injury rates. This is indicated by the 10-year average of 4.46 lost-time injuries per 100 workers in Ontario wildland firefighting compared to 0.95-1.88 lost-time injuries in other occupations, as reported by the Workplace Safety and Insurance Board (WSIB). There is anecdotal evidence that fatigue is a major contributor to injury; however, evidence to support this is limited. Understanding fatigue trends, potential causes, and areas for intervention within the wildland firefighting profession were the main goals of the study.
Accordingly, contributors to fatigue were assessed during non-fire and fire deployments by collecting objective sleep (Actigraphy) and vigilance (Psychomotor Vigilance Test) measures, as well as subjective measures of fatigue and recovery (questionnaires). Data were collected from wildland firefighters during the high-risk months of the fire season within the province of Ontario.
Sleep duration less than six hours, sleep efficiency below 85%, and wake after sleep onset greater than 30 min were more frequently observed during high intensity, Initial Attack deployments. Sleep duration less than six hours were routinely observed in non-fire work periods, placing workers at risk of pre-deployment sleep-debt. Self-reported morning fatigue scores were low-to-moderate and were best predicted by Initial Attack deployment work conducted the day prior. Reaction times were slightly worse in morning periods during Initial Attack deployments, but scores were generally within acceptable ranges. Self-reported recovery scores were generally good regardless of work performed.
The current study highlights suboptimal sleep behaviours during both non-fire and fire suppression work, with sleep measures below recommended standards. High-intensity fire suppression periods (i.e. Initial Attacks) were predictably associated with the worst sleep and fatigue levels; but it is worth noting that the data were collected during a record low-hazard, firefighting season and may not reflect the sleep behaviours and fatigue levels encountered during a high-hazard fire season. Interventions for sleep/fatigue hygiene and awareness should be explored and are further discussed in this paper. The research methodology employed in the current study could be used in future investigations to determine the sleep behaviours and fatigue levels of wildland firefighters during a high hazard fire season.

Dans une perspective postcoloniale et féministe qui articule colonialité et corps des musulmanes
francophones et canadiennes, notre thèse explore dans quelle mesure les expériences du

femmes entretiennent avec leur corps dans le contexte d’aujourd’hui exacerbé par les discours
idéologiques et les violences entre l’islam et l’Occident qui réifient leur corps (femmes voilées,
femmes-burqas, femmes niqabiques). Ses résultats montrent une résistance des musulmanes à
la colonisation de leur corps par une agentivité inédite qui se tente, d’une part, dans une
dépossession des valeurs orientales qui autorisent le mariage colonial, la mutilation sexuelle et
de multiples actes de violence fondés sur le genre, et, d’autre part, dans un essai de
neutralisation des influences de la culture du pornographique, de l’hypersexualisation, et des
discours médiatiques et idéologiques occidentales qui les infériorisent.
