abstract: Prior to the late 1980s, Haemophilus influenzae type b (Hib) was the most common cause of meningitis, epiglottitis, and other invasive bacterial infections in young children. The introduction of the conjugate Hib vaccines dramatically decreased the incidence of invasive Hib disease in young children and is thus recognized as a great public health achievement. Since the vaccine's implementation, there have been concerns about capsule switching and serotype replacement, which may allow non-type b H. influenzae to fill the ecological niche previously occupied by Hib. Recently, reports identifying non-type b serotypes of H. influenzae causing invasive diseases have been published. Moreover, there appears to be a large number of Indigenous people affected by non-type b H. influenzae. This study examined the incidence of invasive H. influenzae disease in Northwestern Ontario, Canada.


title: Sedimentology and geochemistry of the Mesoproterozoic Pass Lake and Rossport formations, Sibley group

subject: Geology Ontario Lake Nipigon Region

subject: Geochemistry Ontario Lake Nipigon Region

subject: Lithostratigraphy

abstract:
The Sibley Group is an essentially unmetamorphosed, Mesoproterozoic
sedimentary succession consisting of a mixture of siliciclastic and chemical sedimentary
rocks. This study examined the sedimentology and geochemistry of the Pass Lake and
Rossport Formations, the lowermost lithostratigraphic units of the Sibley Group.
Lithofacies analysis subdivided the sections studied into sixteen lithofacies
associations corresponding to distinct depositional environments. These were divided
into four informally defined allostratigraphic units, roughly equivalent to previous
lithostratigraphic subdivisions. A lower clastic unit is comprised o f the following
lithofacies associations; boulder conglomerate-sandstone-dolocrete (proximal ephemeral
braided stream), pebble to cobble conglomerate (ephemeral braided stream), massive
cobble conglomerate (transgressive lag, reworking of braided stream deposits during
transgression), trough cross-stratified sandstone (braided stream), green sandstonesiltstone
(wave and storm influenced fiuvial dominated delta), planar cross-stratified
sandstone (nearshore migration of large sandwaves), and thinning-upward sandstone
(beach and storm remobilized nearshore sandstone sheets). The lower clastic unit is
disconformably to confomably, depending on geographic location, overlain by a mixed
siliciclastic-carbonate unit. The mixed siliciclastic-carbonate unit is comprised of the red
siltstone (non-saline lake), red siltstone-dolostone (perennial saline lake, distal from
clastic source) and red siltstone-dolomitic sandstone (perennial saline lake, proximal to
clastic source) lithofacies associations and is sharply overlain by an upper clastic unit.
The upper clastic unit consists of the sheet sandstone (ephemeral playa lake (?) or
perennial lake with increased sand supply with respect to underlying units) and black
chert-carbonate (microbial mats forming at restricted, shallow, subaqeuous shoreline)
lithofacies associations. Subaerial exposure features are present at the top of the blackchert-
carbonate lithofacies association and include the intraformational conglomerate
lithofacies association (subaerial debris flows, intrusive and/or extrusive sedimentary
breccias, terra rossa style soils, dissolution collapse breccias). Subaerial exposure
features at the top of the upper clastic unit are overlain by the massive dolostone (saline
lake), red siltstone-sulfate (wet evaporite-rich mudflats around lake margins) and fine-grained sandstone (dry, evaporite-poor mud and sand flats around lake margins)
lithofacies associations of the mixed siliciclastic-carbonate-evaporite unit.
During deposition of the lower clastic unit paleocurrents and detrital zircon
geochronology suggest a south- to southeast-down paleoslope. A lack o f major thickness
changes in stratigraphie units or laterally extensive coarse-grained clastic deposits is
consistent with a broad intracratonic sag architecture during initial basin subsidence.
Paleocurrents from the upper clastic unit suggest a change to northward oriented
paleoslope during its deposition. This corresponds with an apparent thickening of the
upper two units towards the north and Black Sturgeon Fault, consistent with the
development of a half-graben structure and increased evidence of tectonic activity (e.g.
intrusive sedimentary breccias, synsedimentary faulting and debris flows).
Carbon, oxygen and sulfur stable isotope analyses, Sr isotope analyses and trace
element analyses (in some cases analyses include rare earth elements) were preformed on
a variety of distinct carbonate and sulfate lithologies. Sulfur isotope compositions,
strontium isotope compositions and rare earth element/yttrium ratios support a nonmarine
depositional setting. Low   values appear to be a good indicator of
diagenetically altered samples. values have typical marine values consistent with
lacustrine carbonate precipitated in equilibrium with atmospheric CO2. Stratigraphie
changes in C and O isotope compositions in the red siltstone-dolostone lithofacies
association were likely driven by evaporation and residence time effects. Stratigraphie
variations in sulfur isotope compositions may reflect changes in the composition of
sulfides weathering to supply sulfate to the basin. Overall, both the interpretation of
physical sedimentologic and various types of geochemical data strongly support a nonmarine
lacustrine setting for the deposition of the Pass Lake and Rossport Formations.

Pre-school nature-based program

abstract:
Across Canada, an interest in connecting people with nature is growing, and much of this interest is focussed on young children. This study, which explores the experiences of two early childhood educators as they piloted a preschool nature-based program in Northern Ontario, examines factors that educators might find helpful in implementing a nature-based
early learning program. It specifically focuses on two main areas: a) the impact of this piloting experience on the educators' beliefs about education and their own roles as educators, and b) the educators' experiences of the benefits and challenges of nature-based programming as encountered during this trial period.
A case study approach was used, and data was collected through observations, interviews, and journals. The findings focus on three main themes: a) connecting with nature, b) supporting learning in nature-based programs, and c) examining benefits and overcoming barriers. This study adds to the limited body of Canadian research in this area. Although the size of the study is small, and therefore data should not be used to make broad generalizations, it nonetheless can be used as a prompt for other early childhood educators to reflect on their practices and could act as a springboard for programs that would like to explore and
implement nature-based programs for young children in their communities.

Dental policy Ontario.

abstract:
Has the new health legislation, the Regulated Health Professions
Act, 1994. changed the social organization of health care delivery
in Ontario? My research has shown that this new legislation, which
governs twenty-four health professions, is a site of power
relations.
The seemingly mundane and ordinary practice of oral health care
delivery is examined to find evidence of change in the social
organization of health care. The relationship between two
providers of services surrounding the mouth and oral health care,
dental hygiene and dentistry exemplify the power relations and the
inherent resistance emerging as the legislation is enacted. The
evidence at this time indicates that the existing professional
monopolies may not be disrupted easily, even with new legislation.
The themes that emerged from the struggle to reframe the relations
between dentistry and dental hygiene under the new R.H.P.A. are:
discourse/language, professional dominance, technologies of
bureaucracy, gender, and power/knowledge.


title: Self tuned NFC and adaptive hysteresis based DTC scheme for IM drive

subject: Electric motors, Hysteresis

subject: Device drivers (Computer programs)

subject: Electric motors, Induction Automatic control

abstract: The concept of field oriented control scheme brought the revolutionary change in industrial drives. Due to the high initial and running costs of the DC machines, the trend shifted from DC to AC motor drives to obtain high performance variable speed drives. The major achievement with field oriented control was the decoupled and independent control of stator and rotor quantities like DC machines. It is agreed that the control scheme for ac machines is complicated as compared to DC machines. The inherited problem with the ac machine control is the nonlinear relation between process variables e.g. speed and manipulated variables e.g. current, torque etc. Moreover, magnetic saturation of its rotor core causes developed torque relation of nonlinear nature.

abstract:
Room-temperature STM experiments were conducted for
tribromotrioxoazatriangulene, (TBTANGO), on three surfaces: Si(111)-√3x√3-R30o-B,
Ag(111), and Au(111) on mica. We found for the silicon samples there was a trade-off between
attaining sufficient boron to passivate surface while remaining contamination free. STM
imaging shows TBTANGO fragments were decomposed by surface dangling bonds. Of the
procedures tested to prepare an atomically clean but passive surface, flashing near 1200oC,
followed by annealing for 100 minutes at 930oC was the best.
The (111) face of silver was explored at room-temperature and elevated-temperature
as a molecular substrate. Both instances showed that TBTANGO forms two-dimensional
organometallic structures. At room-temperature, short oligomers were formed. With the silver
crystal at 240oC, large organometallic SAMNs were formed. The molecules formed a
honeycomb organometallic network with trapped bromine atoms within many of the pores.
The honeycomb cell of TBTANGO on hot silver is commensurate with the underlying substrate
within error. The cell is s1 = 19.8 Å, s2 = 19.8 Å, θ = 60.3o. The pore-to-pore separation
distance calculated by gas phase density functional theory was ~22.1 Å. The deposition of
TBTANGO on hot silver also supported a close-packed phase believed to be an organometallic
SA with 3 metal-carbon links.
Thin films of Au(111) terminated facets supported the self-assembly of TBTANGO at a
substrate temperature of 180oC. The unit cell was measured to be s1 = 10.5 Å, s2 = 10.5 Å, θ =
59.2o. Theoretical calculations for the self-assembled cell are s1 = 13.3 Å, s2 = 13.3 Å, θ = 60o.
The discrepancy between the measured is attributed to STM drift.

abstract:
While several proteomic studies have undertaken the challenge of analyzing formalin fixed
paraffin embedded (FFPE) tissue, few have developed optimized protocols for studying
FFPE human brain tissue. This study will examine if an improved SDS free proteomic
method applied to FFPE human brain tissue will produce a greater number of identified
proteins then assess optimized methods to produce reliable, robust and reproducible results
from this tissue. A modified guanidinium hydrochloride based extraction method was
employed and the extracted proteins were analyzed using LC-MS/MS, for shotgun
proteomics. The FFPE human brain tissue samples were acquired from archived specimens
at the Griffith University School of Anatomy. By analyzing tissue samples from human
FFPE brain, we evaluated conditions used for tissue lysis, digestion, and the effects of the
fixation time and storage duration on the number of proteins obtained during shotgun
proteomic analysis on FFPE tissue. Comparing the identified proteins and experimental
procedures to the existing FFPE tissue studies in the literature, the limitations due to protein
quality were identified, optimized processes proposed, and future studies including multiomic analysis of the human brain, were outlined.

abstract:
The purpose of this three year sequential study was to examine factors
contributing to the wellness of 32 self-professed healthy seniors aged 65-74, 75-84, and
85 years of age and older, living in Thunder Bay based on their; patterns of physical
activity; factors contributing to health and well-being; and lifestyle habits. In an attempt to
better understand wellness over time, these respondents were visited each year from
1993 to 1995. Since the number of participants in the oldest group declined from 11 to
three by the third year of the investigation, their responses are not included where they
would violate rules of statistical inference. Walking and gardening were the most popular
activities. Participants in the youngest age group were consistently active in the largest
number of activities of the most vigorous nature over the three year period. The middle
and oldest age groups reported a change by doing less vigorous physical activity over
the three year study. However, further analysis indicated that the middle and oldest age
groups engaged in compensatory behaviour. They replaced vigorous physical activity
with less intense activity and practiced over a longer duration. Participants uniformly
perceived themselves as more active than their peers during adolescence, and also In
each year of the study. Each age group identified regular physical activity, diet, and rest
as the most important factors contributing to health and well-being. Despite their positive
perception of personal health status, all three age groups indicated functional difficulty
with: standing, bending, and hearing. Participants also indicated that they were coping
with chronic conditions such as: arthritis, heart disease, and high blood pressure. The
seniors In this study shared similar lifestyles. Each age group acknowledged the
importance of reaching specific goals such as: Independence, fitness, having fun, and
relaxation. Each group reported doing various leisure activities such as reading, visiting
with friends, and family. Even though the choices that the seniors made in the three age
groups demonstrated some variability, their responses indicate positive aging, and give
us an understanding of wellness. The behaviour of these seniors indicates that they
exhibit the components of successful aging as illustrated by Rowe and Kahn (1998): low
risk of disease, high mental and physical function, and active engagement with life.

abstract:
The assessment of psychiatric attitudes has been inconsistent over the
years despite considerable evidence of the important role which they play
in the efficacy of intervention with psychiatric illness. The development
of an assessment tool which was both modern in theory and terminology was
undertaken with the focus being on item construction and reliability. Three
theoretical dimensions (Restrictive Control; Protective Benevolence;
Humanistic) were consistently identified within the research literature,
and items were written for these dimensions concerning five content areas
(hospitals, treatment, professional staff, patients and illness). The final
vetted battery was administered to 210 individuals, with factor analyses
and reliability statistics calculated. After careful consideration of the
limits of the present study, forty items were tentatively forwarded for
further investigation in the development of a psychiatric attitudes
assessment device.


title: The effects of invasive dreissenid mussels on the offshore food web of Lake Simcoe, Ontario

subject:
Dreissenid mussels
Offshore food web

abstract: Dreissenid mussels have successfully invaded North America, including the Great Lakes and their surrounding waterbodies. With their establishment, there have been many notable impacts including the rerouting of energy flow from offshore to nearshore energy sources. This study aimed to determine if such a shift had occurred in Lake Simcoe, Ontario following the establishment of zebra mussels (Dreissena polymorpha) and, more recently, quagga mussels (Dreissena rostriformis bugensis) with an emphasis on the fishes in the offshore region. With the relatively long time period of 13 years between establishment dates of zebra mussels and quagga mussels, Lake Simcoe provided a unique opportunity to differentiate the possible effects of zebra mussels independently from quagga mussels. All offshore fish investigated in this study appeared to decrease in trophic position (TP), closely following dreissenid invasion, except for lake trout, which increased. Interestingly, for smelt, herring, and lake trout this result may not be due directly to mussel establishment, but rather other factors impacting Lake Simcoe such as changes to the zooplankton community, as well as increased natural recruitment and ongoing stocking practices of lake trout and whitefish. Whitefish trophic position appeared to be consistent with increased dreissenid mussel abundance, as observations of whitefish stomachs in recent years revealed heavy reliance on dreissenids. In addition, and contrary to expectations, the percentage of littoral carbon incorporated in cold water fish decreased over time, especially in the most recent years. A shift towards nearshore resources was observed following zebra mussel invasion in 1996 among all offshore fish species, however, this quickly shifted towards more offshore resources in the following years. Therefore, it appears that the invasion of dreissenid mussels to Lake Simcoe has produced a shift in energy pathways to favour more nearshore benthic-littoral energy production, in a similar manner to observed changes in the Great Lakes following dreissenid establishment. However, shifts in energy pathways in Lake Simcoe were observed to correct back to more offshore pelagic sources in years following initial dreissenid establishment. Ongoing monitoring of the Lake Simcoe offshore fish community is important to understand the effects of dreissenid mussels into the future.

abstract:
Agroforestry is a land management system which integrates forest management
practices with agriculture, often using high-value tree species planted alongside crops to
increase profits. Agroforestry has the potential to increase carbon sequestration from the
atmosphere within an area by increasing or maintaining land productivity through
preventing soil erosion and binding carbon within the soils. As carbon dioxide is the
most abundant greenhouse gas, sequestering carbon dioxide by any means will help to
mitigate the degree of climate change. In this study, I compared the potential carbon
sequestration capacity of shelterbelt agroforestry systems and silvopastoral agroforestry
systems applicable to ecosystems within Canada against that of their adjacent pure
agricultural systems. The results of this study indicated that silvopastoral systems
sequester significantly more carbon dioxide within their soils than their adjacent
agricultural counterparts while shelterbelt systems do not. Potential aboveground
biomass productivity was also compared for hardwood and softwood tree species. The
results indicated that there was no statistically significant difference between the two in
aboveground biomass production potential. Based off these results, recommendations
for resources and policies were made specific to Canada. The recommendations
included developing a strategic framework for agroforestry in Canada, increasing the
availability of grants for agroforestry in Canada, and changing property tax schemes to
make agroforestry more financially appealing to land managers over single-use systems.

subject:
Silicon reactivity
Backbone atoms

abstract:
This thesis describes a study of the inductive effect in derivatives of bicyclo[1.1.1.]pentane; chosen because it eliminates any possibility of conjugation between the substituent and probe, and keeps the steric effect constant by providing a rigid backbone. The substituent effects, both upon a silicon center and transmitting through silicon atoms, in these systems were studied using Density Functional Theory and the isodesmic reaction approach to Hammett's methods. The elctron density distribution was analyzed using the Quantum Theory of Atoms in Molecules.
Although less sensitive to substitution, it was discovered that the effect as
measured on a Si‐probe (–Si(OH)3) is the same as that measured using a C‐probe (–COOH). In both cases, the transmission of the “so‐called” inductive effect appears to operate in the same fashion: through the molecule using the atomic dipole moment. The x‐component (axis connecting the substituent and probe) of the substituent dipole
was determined to be the controlling property. Despite minor differences in structure, replacing the backbone atoms with silicon appears to have little effect upon the mechanism of transmission, but a general decrease in sensitivity, to the effect of substitution, is apparent. As the atomic dipole moment conforms to the principle of atomic transferability, it is possible to describe the inductive effect in terms of the substituent‐only dipole (μx(RH); determined for the RH system). In fact, we were able to
replace the substituent constant, an empirically derived parameter, with μx(RH), a quantum mechanically derived parameter. Linear free energy relationships to describe the inductive effect with μx(RH), as well as an electronegativity term and steric terms to describe the backbone and probe, were developed that essentially recreate the entire substituent effect.

Effectiveness of therapeutic tape

abstract:
Patellar tendinopathy is a common injury found among active populations. Typically,
tendon pain and tenderness are the most prevalent symptoms associated with patellar
tendinopathy and can range from mild to severe. This can be detrimental for active individuals,
considering that the presence of these symptoms can also negatively affect range of motion
(ROM), power, balance, and strength. Currently, there is much discrepancy within the literature
regarding the effectiveness of conservative treatments like Kinesio tape (KT) or Leukotape (LT).
Consequently, it is unknown which type of therapeutic tape is beneficial for decreasing the
common symptoms of this injury when compared to no tape (NT) or placebo tape (PT).
Therefore, the purpose of this Master’s thesis study was to examine the effects of therapeutic
taping on pain, ROM, power, balance, and strength in physically active male and female adults
between the ages of 18 and 45, with patellar tendinopathy.
Using purposive sampling, ten participants were recruited (M = 25 years; SD = 8.0).
Participants committed to four test sessions, each separated by at least one day of rest. One
session was allocated to each of the following conditions: NT, PT, LT, and KT. The baseline
testing session involved NT and the subsequent taping sessions were randomized for each
participant. During the initial NT session, participants were informally interviewed about his/her
injury. The participant’s pain level was then measured and the testing sequence was
implemented as follows: ROM of the knee joint, strength, power, and balance measures. Pain
levels were also measured once again after the participant performed the balance task. To
analyze the differences in perception of pain across the different tapes and times of
administration, a 4 x 2 (Tape [KT, LT, NT, PT] x Time [Pre, Post]) repeated measures factorial
ANOVA was conducted. To examine the potential effects of different taping conditions on ROM, power, balance, and strength, a one-way ANOVA, with taping condition as a repeated
measures factor was used.
There were no substantial differences found regarding pain, ROM, and power, indicating
the effectiveness of therapeutic tape is context specific. From a clinical perspective, therapeutic
tape had a tendency to reduce further pain and increase ROM when compared to NT and PT.
Strength and balance performances were also substantially improved with the KT application.
These results carry several clinical implications that may supplement current rehabilitation
procedures for physically active individuals recovering from this injury. The application of KT
could be the treatment of choice for health care providers who are considering therapeutic taping
as a potential treatment intervention. Future research should consider incorporating more
sophisticated laboratory equipment (e.g., EMG) in order to determine the underlying effects
associated with therapeutic tape in pathological populations.

The focus of the project was to decide if the mixed economy persists in Inuit communities today, or if Inuit have moved into a new form of economy. I explored two definitions of the mixed economy. First, that as a group, women divide their time approximately evenly between monetary and subsistence pursuits; and second, that women devote their time to activities which support their male partners in hunting. A survey was used as the primary research tool to gather data from 103 women regarding how they spent their time over a one month period in spring 2010.

title: Community care providers' perception of dementia in Aboriginal seniors: a qualitative study

subject: Older Native people Care Ontario, Northwestern

subject: Alzheimers Disease Patients Care Ontario, Northwestern

subject: Dementia Patients Care Ontario, Northwestern

abstract:
Little research has explored dementia within Aboriginal communities in northwestern
Ontario; as a result, we know little about the experiences of health service providers in caring for
these populations. This research study focused on community care providers’ perceptions of
dementia in Aboriginal seniors that reside in rural communities in northwestern Ontario. The
study used qualitative research methodology. Eight community care providers were contacted
through purposeful and snowball sampling and were interviewed using open-ended semi-structured
interviews to generate study data. Eight prevalent themes emerged from the data
analysis which was conducted through using the constant comparative method. The emerging
themes include ‘Views of Dementia: A Normal Part of Aging’, ‘The Inaccessible Population’,
‘Crisis and Caregiver Issues’, ‘Dwindling Services and Supports’, ‘Housing’, ‘Continuity of
Care’, ‘Cultural Sensitivity’ and ‘Bright Future’. The study outlines the experiences of
community care providers when caring for Aboriginal seniors with Alzheimer’s disease and
related dementia and what the care provider’s need to deliver these services. The study is focused
on care providers who have lived and worked in small rural and/or northern communities for an
extended period of time to best reflect the realities of caring for Aboriginal seniors living with
dementia in a small community. This study offers a foundation of dementia research in
northwestern Ontario with hopes to guide further research as well as current and future supports
and services for Aboriginal seniors living with dementia in these communities.
The findings indicate the need for the increase of both formal and informal supports and
services in rural and remote communities for Aboriginal seniors with dementia. The research
also exposes the need for educational initiatives surrounding dementia and cultural competency
among community care and health care providers in rural northern communities along with the need for awareness and education in the Aboriginal community surrounding Alzheimer’s disease
and related dementia. This study suggests that community care providers and organizations need
to work together to provide the most effective person-centered, culturally sensitive care for
Aboriginal seniors and to deliver these required supports and services to seniors in a culturally
respectful way.

subject:

Gunn effect
High pressure (Science)

abstract:
The Gunn effect as a function of pressure has been
studied in n~type InSb. The Gunn threshold field is found to
decrease with increasing pressure reaching a minimum at P ~ 9
kbars. It then increases while the oscillations weaken with increasing
pressure up to 12 kbars. Low field Hall and conductivity
measurements have also been made in an attempt to obtain a possible
explanation for the threshold minimum. It is observed that the
impurity level moves away from the conduction band approximately
exponentially with increasing pressure. By 9 kbars the donor ionization
energy is large enough that considerable freeze-out or deionization
of donor states occurs. The reduction in carrier number
is unfavourable to the Gunn process and hence leads to an increase
in the threshold field for pressures above 9 kbars.

Self-perception

abstract:
This study tested Dweck and Leggett’s (1988) social cognitive model of motivation in the
physical domain. It investigated the effects of perceived competence (PC) and goal orientation
(GO) on affective and behavioral patterns in a motor skill activity. The model proposes that
under failure conditions subjects with a low perceived competence and an outcome/win goal
will have high negative affect, and will persist less than the other three groups, who will
continue to display a mastery pattern. The sample 61 university students majoring in physical
education. In phase 1 participants were individually tested on a throwing and balancing task
and completed a "Task Specific Perceived Competence" Scale. The Scale was administered
several days later to determine test-retest reliability (P=.79). The two scores were averaged and
the participants were separated into high or low perceived competence groups dependent on
the score obtained. Participants were then randomly assigned into two GO groups
differentiated by given instructions. In phase 2 subjects experienced four successful trials and
four failure trials on the task. They were told that they could have up to five additional
rehearsals in between each trial. A Positive Affect Negative Affect schedule (PANAS, Watson,
1988) was administered after trial four and trial eight. The data was analyzed by a 2 (PC) by
2 (GO) by 2 (gender) by 2 (success/failure condition) with repeated measures on the last
factor. There was a significant conditions effect for negative affect, F (1,53) = 17.68, p <.001.
Negative affect increased for all groups from success to failure. There was no support for an
interaction between PC and GO. The analysis for persistence revealed a GO by Gender by
Condition interaction, F(l,53) = 4.50, p <.05. Post-hoc analysis using a Scheff^ test revealed
that in success there was no difference between groups. In failure one group (females with an
outcome/win goal) was different from the other three. Across conditions three groups changed
significantly. The only group that failed to change were females with an outcome/win goal
orientation. The findings do not support the hypothesis of an interaction between PC and GO in failure conditions. The results have imphcations for goal setting and instructional methods
used to motivate students and athletes.

abstract:
Over the years, the controller design for an unmanned aerial vehicle has been attracting
considerable amount of attentions and interests. In this thesis, a quadcopter has been studied
intensively, and an adaptive backstepping nonlinear controller, along with altitude control
using sonar sensor, has been proposed to ensure the stable
flight of a quadcopter.
A quadcopter consists of four motors acting as its control means. The proper thrust and
air drags produced by the propellers completes the tasks to stabilize the quadcopter in the
pitch, roll and yaw directions. An attitude estimation technique, the Mahony filter, was
firstly implemented to yield the accurate Euler angles for the quadrotor. To understand
such a complex system, the Euler-Lagrangian equations has been introduced to develop a
dynamic model. Following such a mathematical model, using backstepping design technique,
an adaptive nonlinear controller is designed for and implemented onto a real quadcopter.
The derived mathematical model has its own uncertainties, such as changes in mass and the
location of the center of the mass. Due to such a nature, an adaptive controller based on the
neural network has been proposed to estimate certain nonlinear terms in the mathematical
model. Successfully design and implementation of such a controller can improve the accuracy
of the dynamic model.
The unit quaternion representations was also used to eliminate the Gimbal Lock of the Eular
angles. A different mathematical model based on Newton equations was also used to further
consider the air drag effect of a quadrotor while
flying in the air.
Proceeding to the attitude controller design, an altitude controller is also designed to lock
the
flying height of the quadcopter. The design concepts are based on a traditional nonlinear
backstepping method.
Matlab simulation results suggest a possible implementation of the proposed controller for
the quadcopter's altitude and attitude control. A couple of real time experiments have been
conducted. The results was recorded and analysed.

Keewatin-type and Shebandowan-type, respectively, to avoid
connotations of time-stratigraphic equivalence with type
areas) of the region.
It is believed that the Shebandowan-type rocks are
younger than the Keewatin-type rocks. Although no actual
contact between the two has been seen in outcrop in the
study area, the trend of their contact is discordant with the trend of cleavage in the Shebandowan-type rocks. This,
along with the less recrystallized appearance of the
Shebandowan-type rocks, and the presence of clasts of
jasper in conglomerates of the Shebandowan-type sequence
similar in appearance to the jaspilitic iron formation
interbedded with the Keewatin-type mafic volcanics, leads
to the conclusion that an unconformity separates the two
groups of rocks. Recent geochronological work on some of
the rocks in the region, carried out by the Ontario
Geological Survey, supports this theory.
The macroscopic, microscopic and sub-microscopic
structure of both groups of rocks was examined in detail.
The minor structures seen in outcrop, the examination of
thin sections, scanning electron microscope work, and the
determination of the magnetic fabric of the rocks all show
that the rocks in the present study area contain a single,
penetrative, primary cleavage, which has a consistent trend
across the whole area. The regional structural picture
which emerges from the data is characterized by
close-spaced, isoclinal folding with sub-vertical fold
axial traces trending roughly east-west. Local variations
exist in the eastern portion of the study area where more
widely-spaced and open folding is more common. No evidence
of a second, significant period of deformation in the
present study area has been found.

subject: Pleurozium schreberi

abstract:
It has been determined that carpet-forming mosses are
good indicators of heavy metal deposition, since they are
dependent on their supply of nutrients from above rather than
from the substrate. Samples of the common carpet-forming
pleurocarpous moss Pleurozium schreberi (Brid.) Mitt, and
the underlying soil were collected during the summer and
early fall of 1975 from 105 sites in northwestern Ontario.
Analyses were carried out on all samples for the heavy metals
Cd, Cu, Fe, Hg, Mn, Ni, Pb and Zn, using atomic absorption
spectrophotometry. Results were expressed as ppm (dry weight).
Soil pH and loss on ignition were also measured. The results
were in general agreement with those reported elsewhere in the literature. As expected, moss analysis was shown to be
a more reliable indicator of metal deposition than soil analysis.

Wei, Ruizhong

subject: Wireless communication systems

abstract: Orthogonal frequency division multiplexing (OFDM) technique has been adopted by many existing and future wireless communication systems for high-speed data transmission. However, a major problem of OFDM systems is the high peak-to-average power ratio (PAPR) of OFDM signals, which results in inefficient operations of nonlinear devices in the system such as power amplifiers (PAs). On the other hand, at the receiver end, frequency offset, caused by Doppler frequency shifts, mismatched oscillators, or a fast fading channel, destroys the orthogonality among subcarriers and results in inter-carrier interference (ICI), thus degrades the detection performance of OFDM systems. Analogous to the definition of PAPR, the peak interference-to-carrier ratio (PICR) is defined to represent the effect of ICI. In addition, due to the sidelobes of modulated subcarriers, OFDM systems also suffer from high out-of-band power (OBP) radiations. High OBP results in the need for wide guard band and thus inefficient usage of frequency band.


title: Mindfulness-based cognitive therapy (MBCT) for stroke survivors : an application of a novel intervention / by Amy K. Moustgaard. --

subject: Cognitive therapy

subject: Cerebrovascular disease - Rehabilitation

subject: Cerebrovascular disease - Psychological aspects

abstract:
Stroke can affect neurological, cognitive, and emotional functioning and have a negative impact on overall quality of life (QoL). Published research in the area of psychological intervention for stroke patients suggests that therapy directed toward managing depression and anxiety can result in general improvement in emotional health and QoL.
The purpose of this study was four-fold: (1) to adapt and implement Mindfulness Based Cognitive Therapy (MBCT) for stroke survivors; (2) to evaluate the psychometric properties of generic and stroke-specific measures; (3) to evaluate the effectiveness of MBCT on aspects of quality of life, emotional factors, and adjustment for participants, as
well as caregiver burden; and (4) to determine the predictors of success. Participants (n = 23) completed questionnaires on initial assessment, after the 9-week MBCT Program, and at 3-month follow-up. Questionnaires included the Beck Anxiety Inventory (BAI), Hospital Anxiety and Depression Scale (HADS), Beck Depression Inventory - II (BDIII),
Short Form-36 General Health Survey (SF-36), Stroke Specific Quality of Life Scale (SSQoL), and the Mental Adjustment to Stroke Scale (MASS). Overall, findings indicate that MBCT lends itself to be adapted to clinical groups. Psychometric analysis of measures used showed moderate to strong internal consistency (a = .57 - .95), significant convergent and divergent validity, and adequate responsiveness with moderate to large
efkct sizes (0.32-1.43) on the non-physical indices. Independent t-test analyses showed significant improvement (p < .05) in participant scores (n = 8) on the BAI, BDI-II, HADS, and QoL indices when compared with dropout control scores (n = 4) in the initial control arm (Phase I). Phase II repeated measures analysis of variance for all completers (n = 21) reflected significant change from baseline to program completion, with maintained improvements at follow-up in all domains, including those related to anxiety [see dissertation]
 A decrease in scores on the MASS helplessness/hopelessness subscale significantly correlated with improvement in emotional constructs. MBCT may be useful in the treatment and prevention of depression and anxiety and may improve QoL and facilitate adjustment to changes secondary to stroke. Randomized controlled multi-center trials will be required to
provide further evidence.

abstract:
Back to the 1 960s, Internet originated from the military research of survivable, fault-tolerant and distributed computer networks. Half-century later, quarter of Earth' s population use Internet services. International business transactions are promoted by the accelerated information interaction across the world. With the prosperity Internet brought to our society, its survivability and capacity become an important issue.
We investigate the problem of efficient multipath provisioning in backbone mesh networks by employing pool sharing and traffic decentralization techniques such as working and backup traffic split and mix-routing. With Multipath provisioning, a connection request can be split and diversely routed on to several paths. A feature that has two improvements over single-path provisioning: 1 ) load balancing among working paths, and 2) reducing the bandwidth of backup path. However, these diversely routed paths are subject to the limitation of network topology, which limit the number of available paths that can be found inside the network.

Decolonization

abstract:
After decades of advocacy by Indigenous scholars and communities, Indigenous education in Canadian teacher education is gaining support and status. Throughout Canadian teacher education, the ‘common knowledge’ of pre-service teachers does not include complex understandings of Indigenous peoples, Lands, or history in what is currently known as Canada. Using multiple qualitative research methods in the methodology of the Self-Study of Teacher Education Practices (S-STEP), I investigate how I and eight teacher educators enact critical Place-based education (cPBE) in our Indigenous education in teacher education practice in Canada to trouble whiteness, centre Land, and disrupt settler colonialism. The decolonization of teacher education practices, and of the administrative structures and practices of faculties of education, is necessary to support learning with, from and for Indigenous peoples in support of Indigenous futurities.
As I struggled to teach with Land at the centre and in right relation to Anishinaabe Lands and communities, I examined and transformed my own practice-in-relation alongside my students and colleagues. As the Indigenization of universities proliferates, more questions are emerging about how to do this work well.
This research deeply confirms the dual oppression of Land and of Indigenous peoples that is at the heart of the Canadian identity, but it also offers some answers. Indigenous education in Canadian teacher education must include anti-racist education that contends with white privilege, Land-based learning both in and beyond the classroom, and centring local Indigenous communities by prioritizing relationships and learning contexts with them. These elements, which represent the ethical relationality and right relation necessary to cPBE in Canada, are not supported, rewarded, or remunerated in current university structures. This demands change in how universities hire, how they support critical, Land- and community-based pedagogies, and in how they conduct themselves in relation to the Lands and communities they stand on and serve.

abstract:
The purpose of the study was to examine the differences
between consecutive and concurrent preservice education
students concerning both their feelings of preparedness to
teach and the classroom management and discipline problems
experienced. It also explored the relationship between
students' feelings of preparedness to teach and the classroom
management problems they encounter during their practicum.
This research is essentially exploratory in nature due to
a paucity of literature regarding the differences between the
consecutive and concurrent education students.
Data obtained through the use of the "Student Teachers'
Feelings of Preparedness to Teach" scale and the Haines
Inventory were analysed.
The results of the research reveal that the combined
effects of classroom instruction and practicum are sufficient
to enable students enrolled in a consecutive program to
develop feelings of preparedness to teach equivalent to those of the concurrent students. The results also suggest that
there is no significant difference in the number of classroom
management problems encountered by the two groups during their
practicum. In addition, a low positive correlation was found
between the feelings of preparedness to teach score and the
total score on the classroom management and discipline problem
inventory. The study supports Bandura's (1986) theoiry that
self-efficacy grows out of the reciprocal relationships
between the individual's pre-dispositions, his or her
behaviour, and the environment in which the behaviour occurs.

abstract: Wildfires in the Canadian boreal forest poses a considerable threat to forest inventory, structures and human lives. Traditional reactive methods of fire suppression fail to mitigate this threat and can worsen the problem by causing unnatural fuel buildup. Fuel management, carried out through the application of fuel treatments across a landscape, is a proactive approach to fire hazard reduction which has the potential to decrease fire risk significantly. The problem of selecting the location of fuel treatments is complicated by the uncertainty of predicting when and where fire events will occur.

abstract:
An essential consideration for campus administrators and faculty members is that
students complete their degree with good academic grades. Being able to predict
factors affecting students performance is necessary to help ensure the supply of quality
students. The purpose of this study is to determine the factors affecting transfer
students' academic performance (AP) who are taking Baccalaureate degree in the
university. The sample used in this study includes 996 students (934 males and 62
females). The data was filtered by removing students whose cohort year is greater
than the  first term registered, students who deceased while studying, and students
with a degree other than Baccalaureate degree. The data were analysed using descriptive
statistics and structural equation modelling (SEM) approaches (like Path
analysis and Con frmatory Factor Analysis (CFA)).
Results revealed that (i) male students older than 25 to be a strong predictor of
students' academic performance, (ii) females and the students younger than 21 significantly
complete their studies on-time, (iii) students who are on a Permanent resident
immigration status, have French as their native language or are from India, Pakistan
or other countries perform better, (iv) students from Institute N (anonymised institute)
significantly complete their studies on-time, (v) students' past grades from
Institute L and J shows significant positive effect on their current grades at the
university. Furthermore, students with fewer bridging courses or are from group 3
perform better at the university. These  findings will help institutional planning for
future students.

Benefits of learning outdoors
Outdoor education

abstract:
The benefits of spending time outdoors and connecting with the natural world are
becoming increasingly recognized, with outdoor education gaining more acceptance and
visibility in our society. Unfortunately, traditional schools in Ontario, Canada have not yet
shown that they are well-equipped to offer all students access to the benefits provided by outdoor
instruction. In my experience as an intermediate teacher, I have found that grade 7 and 8 students
feel disconnected from the natural world, yet I and my fellow educators make few attempts to
give them the tools they need to see how interconnected they are with the environment around
them. In order to understand why other intermediate educators stay indoors and do not take
advantage of the outdoor learning spaces and tools around them, I interviewed seven grade 7 and
8 teachers. The teachers all work for the same school board, range in age and experience, and
teach in both rural and urban settings. Most of the teachers interviewed had never really
considered the advantages of taking their students outdoors. They identified barriers to getting
outdoors like curricular expectations, reliance on technology for instruction, and their students’
reactions to learning outdoors. In order for intermediate teachers to get outside to instruct their
students, they will require professional development, including building their knowledge of the
benefits of going outside to meet curricular expectations, and time to work on how best to
integrate outdoor instruction into their teaching practices. Until the education system fully
acknowledges the importance of students learning outside and better supports teachers to do so,
it will be up to individual teachers to do what is best for their intermediate students and get
outside as often as possible to meet curricular expectations.


title: Edge effects of road material and compaction on the regeneration of jack pine in the English River Forest

subject: English River forest

subject: Jack pine ecology

subject: Edge effects on trees

subject: Effects of soil compaction on tree growth

abstract: There is potentially a considerable proportion of harvestable forest area experiencing road edge effects. It may be important to understand these effects and how trees respond to them to improve forest growth modeling systems commonly used for forest management planning. The two objectives of this study are 1) to observe if road material type and road compaction affect the height growth of jack pine trees growing on road edges and 2) to estimate the proportion of forest area experiencing edge effects within the English River Forest Management Unit of Ontario. Results from this study indicated no evidence of a relationship between road material and tree height or between road compaction and tree height. However, a larger sample size may have yielded more meaningful results. The total amount of forest area in the English River Forest experiencing edge effects was estimated to range from 1075 hectares to over 21,000 hectares. These areas represent 0.29% and 8.84% of the maximum harvestable forest area, respectively.

subject: Climatic impacts to inland fish populations

abstract:
Global climate change is occurring and observed warming patterns have had significant
impacts on aquatic environments as trends in water temperature are closely related to trends in
air temperature. In ectothermic organisms such as fishes, temperature is relevant to the
maturation and deposition of gametes during spawning, and lifetime growth potential. By using
historical spawning and size at age datasets spanning 43 years, I estimated more than 100 peak
spawning dates for White Sucker (Catostomus commersonii) and Lake Trout (Salvelinus
namaycush) and described changes in growth of White Sucker to summarize the observed effects
that local climate warming over the past 50 years has had on two economically and culturally
important fishes in Northwestern Ontario. I show how spawning events are dependent on annual
variation in seasonal thermal conditions, and how long-term increases in average fall surface
water temperatures by 1.4oC and decreases to thermal cooling by 87
oCᐧdays in lakes have shifted
the peak spawning date of Lake Trout by 5 days over the past 4 decades. Additionally, I show
how changes in population density, likely as a result from increased survival and recruitment of
juvenile White Suckers have worked to dramatically reduce the body size of White Sucker by
over 90% in weight and 50% in length in some populations. Finally, I discovered that declining
White Sucker body size appears to be a common pattern across an expansive geographic range.
These results fill knowledge gaps in the current literature by providing observational accounts of
climatic impacts to inland fish populations for a highly studied culturally significant species, and
for a lesser considered, but ecologically important species.

abstract:
The effects of four factors on nine attributes of black
spruce (Picea mariana (Mill) B. S. P.) seedlings were
investigated. The seedlings were produced under an
accelerated transplant system that used a 6 ml Castle and
Cooke container. The experiment had two stages. The first
stage investigated the effects of the duration of the
greenhouse phase (DURATION), outplanting date (OUTPLANTING
DATE) and acclimatization of seedlings to outdoor
environmental conditions before transplanting
(ACCLIMATIZATION) on seedling attributes at the end of the
greenhouse phase. The seedling attributes were height and
the number of roots outside the growing medium. The second
stage investigated the effects of these same factors plus
shade in the transplant beds (SHADE) on seedling attributes
during, and at the end of, the first growing season.
Seedling mortality in the transplant beds and bud-set were
monitored during the growing season. Total height, top dry
weight, root dry weight, bud diameter, and root collar
diameter were measured at the end of the growing season.
Analysis of variance was used to investigate the effects of
the factors on the response variables. The major conclusions
were these. The greenhouse cultural factors studied affected
both the morphological state of the seedling and its
physiological fitness at the time of transplanting. DURATION
was especially influential in this regard. At 7 weeks the
seedlings were small and experienced high mortality if
transplanted. By 10 weeks the seedlings were larger and survived the transplanting operation well, but they were
predisposed to set bud soon after transplanting.
Thirteen-week-old seedlings were even larger, and were
beginning to outgrow their containers. They survived
transplanting well, but were even more predisposed to set
bud. DURATION effects also influenced the morphological
state of the transplants at the end of the first growing
season. Seedlings that set bud early had short, stocky stems
with large buds and a high root:top ratio. Seedlings that
did not set bud early had tall slender stems with small buds
and a low root:top ratio. OUTPLANTING DATE, SHADE and
ACCLIMATIZATION also affected the crop and interacted with
DURATION and one another. The results provide insight into the first year response of seedling grown under the Castle
and Cooke accelerated transplant system to cultural factors
over which nurserymen have control.

abstract:
The advances in Information Communication Technology (ICT) in the past three decades have served to improve the lives of older persons globally. While this evolution of ICT has in large measure benefited older Canadians, it has also resulted in their alienation from many activities in mainstream society. This alienation has been attributed to the rapid advance of ICT, and the slow rate at which older Canadians are adopting and using mainstream computers, new mobile communication devices and Internet services. Therefore, this thesis sought to explore how older persons in Canada are adopting and adapting to using these different technologies, in formal and informal settings.
This study utilized a qualitative descriptive methodology as the strategy of enquiry. Using inclusion criteria and purposive sampling, semi-structured face-to-face interviews were used to collect descriptive data from ten participants in Thunder Bay, Ontario, Canada. The ages of the participants ranged between 67 to 81 years. Participants were selected from varying backgrounds, with different experiences using and interacting with ICTs.
The interview data was transcribed and coded into distinctive themes, and analyzed using conventional content analysis. These themes were used as the basis for presenting and discussing the findings. While some negative emotions could be attributed to the adoption behavior of a few participants, generally the findings suggest that Canadians 65 years and older in this study are adopting and using mainstream, computers, new mobile communication devices and the Internet on a regular basis.

title: Pre- and post-forest management investigations of factors affecting sediment movement in riparian areas in Northwestern Ontario

subject:
Effect of logging on riparian areas
Forest management
Timber harvesting

abstract:
The principal objectives of this study were to measure the impacts of timber harvesting
on sediment transport rates (mineral and organic) associated with two clearcut areas in
northwestern Ontario and to evaluate the sediment controlling effectiveness of 30 m
wide riparian reserves that were prescribed in accordance with Ontario’s Timber
Management Guidelines For The Protection Of Fish Habitat Guidelines (OMNR, 1988).
A goal of this study was to provide a practical means for assessing potential changes to
sediment transport rates resulting from impacts of forest management activities in
Ontario. Prior to road building and full tree logging with feller bunchers and grapple
skidders, a sediment sampler was installed in each of 16 sub-catchments. Samplers were
situated at a distance of either 0, 10, 20, or 30 m, measured into the reserve areas from
the boundaries of planned clearcuts. Mineral and organic sediment collected in the
samplers were monitored for one year (late spring to late fall) before, and two years (late
spring to late fall) after impacts, and data were standardized with the amount of
precipitation that fell during the respective sampling year. Indices of change were
calculated to quantify differences in mineral and organic collection rates for each
sampler in the first or second post-impact year compared to those in the pre-impact year.
Field and GIS data (including: sampler position in the reserve, sub-catchment area,
distance from road, presence of surface runoff, occurrence of trees thrown by wind,
crown closure, thickness of soil organic layers (LFH), terrain slope, and a topographic
index (TI) derived from GIS data describing upstream contributing area and slope) were
collected in an attempt to quantify the capacity of the reserve areas to impede (or
encourage) sediment collection in each sampler. The results clearly demonstrate that
sediment movement in riparian reserve areas does not increase universally following
forest management. Sediment attenuation through the reserve areas was variable,
indicating that factors in addition to the width of a filter strip can function to control the
distance to which eroded sediment is transported. Catchment area was not related to the
rates that sediment was collected in samplers. Sediment collection rates were higher in
samplers located closer to the road; however, the results can not be used to support
categorically the accepted model whereby areas closer to roads are subject to higher
erosion rates than areas further away from roads. The occurrence of surface runoff and
windthrow, especially when combined, were predominant factors that contributed to
increased sediment collection rates in samplers. The amount of crown closure and the
thickness of LFH layers influenced rates of erosion, but the magnitudes of their
influences were marginal compared to those of flow and windthrow. Steeper slopes did
not consistently generate higher sediment transport rates, but the evaluation of the effects of slope on sediment transport rates was limited by the narrow range of slope
conditions that were evaluated by this study.

abstract:
This thesis explores the technologies apply in silviculture activities. Silvicultural
activities are an essential process in forest management. To meet management
objectives, the forester requires to collect any data, information on the site and do
silviculture practices like thinning, tending, and harvesting. Back at the beginning of 20
century, manpower was the primary tool in doing silviculture activities. With the
development of science and technology, more handy tools appeared, helping us do
silviculture activities. The leading technologies that we use today are geographic
information systems (GIS) and remote sensing. They can gather a large amount of
information with a few operators. With GIS, we can update the site's information in a
short period to monitor the site and change management strategy. A smartphone is also
an excellent tool to improve site data collection. Smartphone has many valuable
applications like a map, a global positioning system (GPS), and digital camera. It is a
useful technology for the student with a limit budget. However, limit by its saved data
and running speed, the smartphone is more suitable for small-scale forest management
than large-scale forest management. More and more foresters use UAV LiDAR to get
3D information to get precise details of trees. The 5G era is coming. With the faster
computer running speed, what will silviculture activities be like in the future? Just
imagine a drone can do every silviculture practice on the site. People do not need to take
a risk to do some dangerous silviculture practices. This thesis mainly discusses the
technologies that apply in silviculture activities to analyze the pros and cons of those
technologies.

Globalization (Health aspects)

abstract: The purpose of this study was to assess the impact of corporate downsizing; a function of globalization, on the self-reported physical and mental health of unionized individuals employed in the primary sector of the workforce. An analysis of the literature revealed that downsizing negatively affected the physical and mental health of survivors of job cutbacks and their respective family members. Survivors of job cutbacks had worse self rated health and higher rates of long standing illness than their unaffected counterparts. Downsizing was found to have a negative impact on the nature of work and social relationships. Job insecurity; or perceived job insecurity, perpetuated by impending or past downsizing in the workplace was found to have long term negative health consequences. Rather than adjusting over time to stressful working conditions, employees appeared to lose their ability to cope. The negative health effects of downsizing were not limited to the survivors of job cutbacks. Marital tension in the home increased with increasing levels of perceived job insecurity. Physician consultation, hospital referrals and hospital attendance increased not only among workers who were experiencing or perceived an upcoming period of job insecurity, but increased for the workers respective family members as well.

abstract:
Radiation therapy often produces considerable anxiety in patients. One reason for this anxiety is the uncertainty that often surrounds this treatment. Since studies have shown that many patients experience the most distress during times that are uncertain, it is understandable that most individuals with cancer desire information about their disease, its treatment, side effects, etc. Unfortunately, many patients do not receive the information necessary to dispel any of the preconceived misconceptions they may have about radiation therapy. The purpose of this study was to examine levels of radiation therapy knowledge and its influence on patients.
Patients who were about to receive radiation therapy for the first time at the Thunder Bay Regional Cancer Centre were solicited as participants for this study. Twenty-seven patients, 12 males and 15 females, agreed to participate in the present study. Prior to their first meeting with a radiation therapist, participants were approached by a nurse, told about the study and asked to complete the State Trait Anxiety Inventory, the General Health and the Radiation Therapy Questionnaire. The questionnaires were also completed by each subject on the last day of treatment.
Although state anxiety decreased significantly and Radiation Therapy Questionnaire scores
increased significantly at  post-treatment,  this did not appear to be the  result of  any relationship between anxiety and radiation therapy knowledge (as measured by the Radiation Therapy Questionnaire). However, this did indicate  that patients acquired information about radiation
therapy throughout the course  of treatment.  Further psychometric examination  of the
Radiation Therapy Questionnaire is necessary before  using this
measure as a screening instrument of radiation therapy knowledge.

abstract:
Currently, limited information is available on lignin-based hydrogels, but its potential in commercial applications presents a promising avenue for the utilization of lignocellulosic materials. Recent studies have employed an array of techniques for crosslinking various types and species of lignin, combined with both synthetic and natural polymers.
This MSc thesis elaborated on effects of incorporating kraft lignin supplied in hydrogel production The hydrogels were synthesized through the radical polymerization of kraft lignin and N-isopropylacrylamide (NIPAAm) with N,N’-methylenebisacrylamide (MBAAm) as the crosslinker, and azobisisobutyroitrile (AIBN) as the initiator. The MANOVA and Tukey Post Hoc analyses determined that the reaction temperature, time, NIPAAm content, and pH exhibited significant effects on the responses for both the control and lignin-based hydrogel Taguchi L9 models. The hydrogel samples were optimized using the SN ratio to maximize yield and swelling ratio; these were determined to be samples 3C and 6C, as well as 2L and 9L, for the control and lignin-based hydrogel models, respectively. The structural analysis of the hydrogels was analyzed using 1H NMR, FTIR, and CHNS, and indicated a high content of NIPAAm within the gels. TGA and DSC indicated an increased thermal stability due to the incorporation of N,N’-methylenebisacrylamide and lignin. The glass transition temperature (Tg) of the hydrogels was also found to be present between 141.45degC to 148.60deg.C.
In addition, the swelling behavior of the lignin-based hydrogels in water was found to obey pseudo-Fickian diffusion and second order kinetics. This was also found to correlate with the surface properties of the hydrogels determined by surface area analyzer (via BET method); an increase in surface area, as well as pore volume and size, leading to higher swelling rates and capacities, respectively. Moreover, the equilibrium absorption of the hydrogels in methylene blue dye was found to better follow the Freundlich isotherm model, indicating a heterogeneous surface.
Furthermore, the oscillatory rheological measurements conducted to determine the viscoeleastic properties of swollen hydrogels. The hydrogels were found to be predominately elastic, for which the amount of energy dissipated was greater for the control samples than for the lignin-based samples. The structure recovery of the control hydrogels indicated a well-developed polymer network, recovering 87.2% to 96.7% of their elastic moduli following 100% deformation. The lignin-based samples, however, were found to withstand a higher amount of applied stress, indicating that lignin improved the flow point of the hydrogels. In addition, the elastic properties of the hydrogels were found to decrease with increasing temperature, exhibiting a lower critical solution temperature (LCST) between 34deg.C to 37deg.C.

volcanic rocks, with porphyry-related alteration and mineralization thought to be related to the
emplacement of the Jurassic Island Plutonic Suite (181 – 141 Ma).
Whole-rock geochemistry, high precision geochronology combined with trace element
and Hf isotope analysis of zircons from various intrusive units has led to an improved
understanding of the magmatic evolution of plutonic rocks at Pemberton Hills. The oldest unit is
a granodiorite dated at 172.34 ± 0.11 Ma. Following this is a quartz diorite with an age of 172.01
± 0.17 Ma, which overlaps with a tonalite dyke sample dated at 171.77 ± 0.13 Ma. A second
quartz diorite sample yielded the youngest reported age at 171.44 ± 0.25 Ma. These results imply
that felsic and intermediate plutonism were broadly synchronous at Pemberton Hills. [...]


title: Interactive effects of elevated CO2 and temperature, nutrition, and ectomycorrhizas on morphological traits and summer shoot formation in jack pine

Shoot and root morphology

abstract:
Understanding the responses of trees, ectomycorrhizal fungi (ECM) and their association to
climate change can be challenging due to their interactions with multiple environmental factors.
The combined impacts of elevated CO2 and elevated temperature on tree growth are mostly
positive, but the impacts to ECM are less well understood. The objective of this study was to
investigate how the elevations of CO2 and temperature and soil nutrient supply interactively
affect the formation and growth-enhancing efficiency of ECM, as well as the formation of
summer shoots and morphology of jack pine seedlings. One-year old jack pine seedlings were
exposed to ambient CO2 and temperature treatment (ACT: 410µmol/mol CO2 and current
average temperature) and elevated CO2 and temperature (ECT: 750µmol/mol CO2 and current
+6°C temperature) as a single treatment, two nutrient levels (low nutrient LN vs. very low
nutrient VLN) and with or without Hebeloma longicaudum (Pers.)P.Kumm (yes ECM or no
ECM) inoculation. The ECT treatment increased total seedling biomass, root biomass and root
collar diameter (RCD), and most summer shoot formation and growth attributes. The VLN
treatment reduced all growth attributes except for height increment, and height increment +
lammas shoot length. An interactive effect of the CT and N treatment was observed for the RCD,
suggesting that lower nutrient sites may limit the positive affects of elevated CO2 and
temperature on tree growth, and the interactive effect on specific leaf area (SLA) suggests that
the lower nutrients limited the needles’ ability to accumulate carbon at ECT. Another interactive
effect observed on SLA suggests that ECM inoculation allowed for better nutrient uptake and
caused seedlings to demonstrate a higher SLA at VLN under ECT. Both ECT and LN increased
the probability of summer shoot formation. The results suggest that jack pine is less likely to
produce summer shoots on nutrient poorer sites, and in current CO2 and temperature growing
conditions. Furthermore, we observed significant two-way and three-way interactions that
suggest the ECT treatment increased the effectiveness of ECM inoculation in forming
mycorrhizae clusters, and reduced the degree of nutrient suppression to mycorrhizal root cluster
formation. The results of this study highlight the importance of incorporating multiple factors
when evaluating tree responses to climate change, particularly in controlled-environment studies.


title: Effect of photoperiod on apical growth cessation in tamarack (Larix laricina) and balsam poplar (Populus balsamifera) provenances from northern Ontario

subject:

abstract:
The effects of four photoperiods (i.e. 6, 10, 14, and 18 hours) on the rate of apical
growth cessation and apical bud primordia production were studied in controlled
environment experiments using tamarack {Larix laricina (Du Roi) K. Koch) seedlings and
rooted cuttings, and balsam poplar {Populus balsamifera L.) rooted cuttings from
provenances in northern Ontario. The objectives of this study were to investigate 1) the
effect of photoperiod on shoot growth and the rate of growth cessation among provenances
of tamarack and balsam poplar, 2) the variation in the rate of growth cessation between
species from northern Ontario, and 3) the effect of different photoperiods on apical bud
primordia production among tamarack provenances. First-year tamarack seedlings from
four provenances in northern Ontario, balsam poplar rooted cuttings from five provenances
ranging from Rhinelander, Wisconsin to Hudson Bay, and two-year old tamarack rooted
cuttings from five provenances in northern Ontario were tested. Tamarack provenances
displayed significant variation in the critical daylength for inducing growth cessation, but
did not vary in the rate of growth cessation. Tamarack seedlings produced twice as many
axial needle primordia in apical buds under a 10 hour photoperiod than a six hour
photoperiod. Balsam poplar displayed clinal variation in the critical daylength for inducing
growth cessation and in the rate of growth cessation. The variation in the rate of growth
cessation during short photoperiods was seen as an adaptation to an increasing rate of
change in daily photoperiod with increasing latitude.

title: Effects of alternative conifer release treatments on terrestrial gastropods of regenerating spruce plantation

subject:
Gastropods Effect of herbicides on
Spruce Growth Ontario, Northwestern
Gastropods Effect of reforestation on

abstract:
This study examined changes in terrestrial gastropod densities and species
richness associated with alternative methods of managing competing vegetation on
regenerating spruce plantations. Data were collected monthly from June to September in
1995 and 1996, the second and third years following use of four conifer release
treatments (herbicides. Vision® and Release®; manual clearing, brushsaw and mechanical
clearing, Silvana Selective/Ford Versatile) on each of four replicate blocks. A total of
15,083 terrestrial gastropods, comprising 21 species, was collected from litter surface
sampling sites (beneath cardboard sheets) over the two years. In 1995, recorded
gastropod densities were low (4.2 ± 0.2m-2)(Mean ± S.E.) during an unusually dry
summer and were similar among all treated and control areas. With wetter conditions in
1996, these numbers increased on all areas (6.9 ± 0.3 m-2, but were significantly lower on
areas treated with herbicides (see document). This may
be attributable to variability in near ground temperature and relativity humidity. As well,
the decreased accumulation of broadleaf litter in these sites may have provided
inadequate habitat conditions during dry periods. Despite this difference in surface active
gastropods suggested by cardboard sheet collections, no difference in numbers was
apparent in a limited number of soil core samples taken from untreated and Vision®
treated sites (258 ± 145 and 377 ±221 m-2, respectively).
Overall gastropod densities were highest where soil moisture, pH and calcium
concentration were highest. Gastropod densities measured by surface sampling cardboard sheets were greater on a regenerating plantation than on an unharvested forest and on a
complete removal plot (CRV), where vegetation was removed annually using Vision®
(9.4 ± 0.5,6.7 ± 0.4 and 6.4 ± 0.5 m-2, respectively). These differences may be
attributable to the more abundant near ground vegetation and larger broadleaf component
of the litter layer in the regenerating plantation. Species richness was similar among these
sites, but several species were not collected on all CRV plots.

abstract:
A modified version of the Harvest Schedule Generator model (HSG) was used to
predict the economic wood supply from alternative silvicultural systems on a case study
forest (Seine River Forest) In northwestern Ontario’s boreal forest. Alternative
silvicultural systems were compared with traditional clearcut harvesting to determine
the impacts on sustainable harvest levels, wood costs and residual timber value.
Results show large reductions in harvest volumes, increased harvest area and
decreased profit for alternative silvicultural systems. Alternative silvicultural systems’
savings in regeneration costs did not offset the increased harvest and delivery costs
nor the reduced volume productivity from the forest as a whole. The different
silvicultural systems resulted in little variation in the residual forest age-class structure
after 200 years when harvest levels were equal. Based on the assumptions used in
this study, the use of alternative silvicultural systems as a replacement for clearcutting
in northwestern Ontario’s boreal forest would produce undesirable socio-economic
impacts.


title: Database anonymization and protections of sensitive attributes

subject: Database security

abstract:
The importance of database anonymization has become increasingly
critical for organizations that publish their database to the public. Current
security measures for anonymization poses different manner of drawbacks. k-anonymity
is prone to many varieties of attack; !-diversity does not work well
with categorical or numerical attributes; t-closeness erases too much information
in the database. Moreover, some measures of information loss are designed for
anonymization measure, such as k-anonymity, where sensitive attributes do not
play a part in measuring database's security. Not measuring the re-distribution of
sensitive attributes will result in an underestimate for information loss such as 1-
diversity or t-closeness which intentionally tries removing the association between
non-sensitive attributes and sensitive attributes for better protecting individuals
from being indentified.
This thesis provides a more generalized version of !-diversity that will
better protect categorical attributes and numerical attributes and analyzes the
effectiveness and complexity of our new security scheme. Another focus of this
thesis is to design a better approach of measuring information loss and lay down
a new standard for evaluating information loss on security measures such as 1-
diversity and t-closeness and quantify actual information loss from deliberately
hiding relations between non-sensitive attributes and sensitive attributes. This
new standard of information loss measure should provide a better estimation of
the data mining potential remained in a generalized database.
This thesis also proves that unlike k-anonymity which can be solved in
polynomial time when k=2. 1-diversity in fact remains NP-Hard in the special
case where 1=2, and even when there are only 2 possible sensitive attributes in
the alphabet.

abstract: The Observabilty Range Space Extraction (ORSE) algorithm used to identify a an initially overparameterized discrete-time state-space model for a single-link flexible manipulator.  A controller named PDPC is designed to control rigid body motion, have a zero tracking error and minimum vibration.--Abstract.

abstract:
The Observability Range Space Extraction (ORSE) algorithm is successfully
applied to identify an initially overparameterized discrete-time state-space model for
a single-link flexible manipulator. Several critical issues related to the experiments
and the implementation of the ORSE algorithm are addressed.
A new model reduction and updating technique is proposed and applied to reduce
the identified models. To quantify the contribution of individual modes to the
responses, a new measure referred to as modal response magnitude (MRM) is
developed and successfully applied to obtain a lower-order model by retaining the
most significant modes. To correct errors caused by the model reduction, either the
reduced input or output matrix is recalculated by a least squares solution.
Based on the updated reduced-order models, a controller named as PDPC is
designed to ensure a good tracking accuracy and robustness to payload changes. The
experimental results show that the PDPC control structure is effective in controlling
rigid body motion to have a zero tracking error and the minimum vibration as well.


title: Exterior characteristics and internal wood decay of hazard trees in Thunder Bay, Ontario

subject:
Tree hazard evaluation
Trees Decay
Wood decay
Thunder Bay (Ontario)
Urban forests

abstract:
One major component of urban forestry is the ability to recognize hazard trees and have them removed before they fail or cause damage to people or property. Thunder Bay's urban forest consists of approximately 20,000 street trees, many of which are at the end of their lifespan and becoming hazardous. Each year 200 or more street trees are removed by the city which provided an opportunity to undertake this research project to identify and possibly equate the relationship between exterior characteristics of trees deemed hazardous, with interior damages, i.e. wood decay. Secondary objectives of this project included measuring the occurrence and diversity of wood decay fungi on street trees in Thunder Bay, creating a resistograph measurement atlas, and determining if a relationship
between resistograph measurements and wood strength values (density and MOE) is possible.
In total, exterior characteristics were measured on 177 hazard trees destined for removal, 65 in the summer of 2011 and 112 in the summer of 2012. Of the trees measured, 19 species were represented, with white birch (26%), silver maple (16%), green ash (14%), and Manitoba maple (9%)
being the most commonly occurring. White birch had the lowest health ratings, with crown die-back brought on by drought stress and bronze birch borer infestation. Damage by severe pruning on major limbs resulted in extensive decay observed among many of the white birch. Silver maple exhibited a decrease in trunk health and structure with increasing age. Large pruning wounds which facilitated invasion by decay fungi, and co-dominant forking were common problems encountered on silver maple.
Green ash experienced damage to foliage and exhibited twig and branch die-back in the lower crowns of trees due to ash anthracnose.
Although discs should have been removed from all 177 street trees, only 26 tree discs from this pool of trees were collected by Parks crews. An additional 44 tree discs were collected by Parks crews that came from trees not on the original tree removal lists. Due to the small sample size for each tree species, it was not possible to find a correlation between exterior characteristics and internal defects. However, all tree discs (70) were photographed and drilled with a resistograph (IML Resistograph F-series) and are illustrated along with the resistograph charts in Appendix III. Cracks and advanced decay were readily recorded with the resistograph, but incipient decay was not detected as it had readings similar to sound wood. A significant source of error noted was drill bit deflection caused by knots in the wood, contours, and meandering growth rings.
One hundred and one trees were observed to be colonized by decay fungi, 22 of these trees were among the original 177, while the remaining trees were additional street trees observed in Thunder Bay. Twenty seven species of decay fungi were recorded, and among these, Cerreno unicolor,
Hypsizygus tessulatus, Pholiota aurivella, Chondrostereum purpureum, Pholiota squarrosa, and Ganoderma applanatum were among the most commonly encountered. Particular attention needs to be paid to silver maple and white birch which were most heavily infected. Green ash exhibited the lowest infection by decay fungi.
Sixteen resistograph readings from two bolts from a silver maple were taken to compare the values on the y axis with actual wood density and MOE values. Results of a linear regression model suggest that a relationship exists. Although more trees would need to be tested in order to strengthen
the interpretation of the relationship. This could provide for a methodology to be created which would give urban foresters measurements that could more accurately predict when a tree is likely to fail.

abstract:
The intent of Ontario's "Timber Management Guidelines for the
Provision of Moose Habitat" is to use timber management to
maintain or improve the moose habitat potential of a forest. In
the boreal forests of Ontario, timber management without
consideration of these guidelines has followed a pattern of
progressive clearcutting. Economics was the most important
factor in determining harvest patterns. Timber management
following the guidelines requires that moose habitat play a
prominent role in the design of timber harvest patterns. The
guidelines are part of an overall objective to double the size of
the moose population in the province by the year 2000.
The objective of this study was to test the efficacy of
components of the guidelines by comparing two timber management
scenarios, one following the guidelines, the other not. A
habitat supply model served as the assessment tool. The study
area was the Aulneau Peninsula on Lake of the Woods in
northwestern Ontario.

abstract:
"The CCF is not a 'Class' Party”: Labour and Politics at the Lakehead, 1944-1963” is a study of
the organized labour movement in the Lakehead from 1944 to 1963. This study analyzes the new
sophistication of the organized labour movement and labour’s relationship to politics in a period
of rapid change for the Lakehead. ““The CCF is not a Class Party”” argues that, between 1944
and 1963, the organized labour movement and the Cooperative Commonwealth Federation
(CCF) at the Lakehead underwent parallel structural developments against the backdrop of
conservative social forces in the postwar period that, by the end of the 1950s, necessitated a
merger of the two formally distinct entities. The amalgamation of labour and politics, resulting in
the formation of the New Democratic Party (NDP), is best examined through the political career
of Douglas Fisher, who first represented the CCF and, later, the NDP in Port Arthur. The debate
surrounding the ‘New Party’ idea in the late 1950s at the Lakehead is reflective of the uneasy
relationship between labour and politics that had formed throughout the postwar period.

abstract: Bioconversion of lignocellulosic residues is initiated primarily by microorganisms such as fungi and bacteria which are capable of degrading lignocellulolytic materials. Fungi produce large amounts of extracellular cellulolytic enzymes including endoglucanases, cellobiohydrolases (exoglucanases) and β-glucosidases that work efficiently on cellulolytic residues in a synergistic manner. The ascomycete Hypocrea jecorina (anamorph Trichoderma reesei), an industrial (hemi)cellulase producer, can efficiently degrade plant polysaccharides. However, the biology underlying cellulase hyperproduction of T. reesei, and the conditions for enzyme induction in this organism are not completely understood. In this study, the optimum conditions for cellulase production by T. reesei strains were investigated. Three different strains of T. reesei, including QM6a (wild-type), and mutants QM9414 and RUT-C30, were grown on 7 soluble and 7 insoluble carbon sources, with the latter group including 4 pure polysaccharides and 3 lignocelluloses. Maximum cellulase activity of QM6a and QM9414 strains, for the majority of tested carbon sources, occurred after 120 h of incubation, while RUT-C30 had the greatest cellulase activity after around 72 h. Maximum cellulase production was 0.035, 0.42 and 0.33 μmol glucose equivalents using microcrystalline celluloses for QM6a, QM9414, and RUTC-30, respectively. Increased cellulase production with the ability to grow on microcrystalline cellulose was positively correlated in QM9414 and negatively correlated in RUT-C30.
