▼ When the price of oil fell in 2014, Canada’s economy suffered. Even now, two years later, companies continue to drop their prices to stay competitive, as the global supply of oil remains great without any corresponding demand. No end has been predicted for the declining price of oil, which means the country must consider investing in new opportunities to generate revenue. Canada has been dependent on the exportation of its natural resources since its founding, from fur to lumber to minerals; the mining sites in Ontario’s Far North, dubbed the Ring of Fire and hailed as the province’s own oil sands, represent the next logical investment. However, the current model of temporary settlements used at resource extraction sites requires rethinking, as these settlements promote extraction based on a shadow population of transient and predominantly male workers, and permit mining companies to exploit both the land and local populations. While boomtowns may present a more permanent alternative, the First Nations communities are not suited for the explosive growth mining will bring to the region.
This thesis proposes a new settlement typology for resource extraction, in which workers embrace a mobile lifestyle of mining operations, moving from one mining site to another with their families according to the lifespan of the extraction in a given region of the Ring of Fire. Parts of the settlement are designed for constant population fluctuation, while others are designed for permanence, forming a resilient economic core to stabilize the resulting community. Local ways of life, such as hunting and fishing, are merged with the resource extraction requirements of the settlement and supplemented with social gathering spaces, operation monitoring and education programs, all in order to create a community conscious and considerate of the land it occupies, benefiting the region socially and economically. A new hybrid landscape is created using the byproducts of extraction to create productive networks throughout the region: these byproducts will increase connectivity and the circulation of various resources, such as electricity and drinking water, both of which are currently lacking in the underserviced communities of Ontario’s Far North. Ultimately, this thesis explores what a settlement providing maximum benefits to both an existing and newly-embedded population—as well as benefits to the country as a whole, through the resulting economic activity—might look like.
This thesis also explores the reincorporation of a community into its surrounding landscape once extraction is complete. What architectural elements (pieces or entire buildings) should remain for the benefit of the communities? What elements can be entirely removed and relocated to other resource extraction sites? And can pieces of architecture be left behind to enhance landscape for those who will remain to inhabit the land? The Ring of Fire has the potential to be so much more than a mining operation, but this requires an accompanying vision of settlement…

▼ The continuous pursuit of reducing drag in many speed sports, such as cycling and ice-skating, demands novel approaches to gain further insight into flow phenomena around athletes. In recent years, the Ring of Fire measurement technique has emerged as a feasible option to visualise and analyse flow structures of transiting objects based on particle image velocimetry. The accuracy of this on-site measurement technique has not yet been validated under equal test conditions. This master's thesis aims to compare drag area values of a cyclist from Ring of Fire measurements to simultaneously acquired power meter data. Tests with the cyclist in upright and time-trial posture, as well as different helmet types and various drafting distances, are envisaged to assess the correlation between the two measurement techniques in multiple drag area regimes, and to gain insight into large distance drafting above 3m, which, to the best knowledge of the author, has not yet been studied in academic research. In addition, the campaign plans to remove any user operations during the test, which would be another step towards a fully autonomous Ring of Fire system, as envisioned in the future. A spacious indoor facility is suggested as the testing site to minimize environmental effects and to allow for the continuous motion of the cyclist. The Ring of Fire method shows great potential, as the measurements are conducted under simulated racing conditions and wake visualisation allows the operator to locate origins of drag. Validating the drag area results could further attest to the Ring of Fire's viability as an optimisation tool in the upcoming years. The conducted campaign, within the framework of this thesis, indicates good agreement between the power meter and Ring of Fire techniques when assessing the relative drag area delta of a small-scale helmet change and a large-scale posture change. In terms of absolute values, the power meter model shows a high dependency on underlying model constants. Using literature-based coefficients, the absolute CdA values are within 5% of the Ring of Fire derived values. Furthermore, the feasibility of evaluating long distance drafting effects with the Ring of Fire system is demonstrated. Measurable drag area savings of 15% are obtained by the trailing cyclist at front wheel to front wheel distances of 7-9m. Due to non-uniform inflow conditions in front of the trailing cyclist, a wake contouring algorithm needed to be employed to satisfy mass preservation within the control volume by resizing the inlet and outlet plane. In addition, enclosure of the wake structure and contouring of a representative inlet plane is achieved. The flow topology in the wake of the trailing cyclist is acquired by a stereo-PIV system. Primary wake structures, as well as in-plane velocity fields, are comparable to those observed behind isolated riders.

▼ Aerodynamics investigations in speed sports generally consist of measurements of aerodynamic loads through wind tunnel experiments. Lately, a new technique has emerged, known as the Ring of Fire. It is the only drag measurement technique capable of retrieving flow field data on-site, by using Large-Scale PIV. In this Ring-of-Fire project a Low-Speed PIV system is implemented in an indoor facility and used to test an amateur cyclist in both pedalling and non-pedalling conditions. Twenty cyclist’s passages can be executed in thirty minutes and provide a mean drag area with an uncertainty equal to 2%. Drag differences equal to 6% are measured between two postures. Limitations arise due to the lack of repeatability of seeding density and cyclist’s position. With the contribution of this research, the Ring of Fire becomes a more mature technique to investigate speed sports aerodynamics, with future applications to curvilinear trajectories and multiple athletes.

▼ Aerodynamics plays a significant role in the field of cycling as it is the dominant resistive force at racing speeds of 50 km/h. Sporting events involving multiple cyclists leads to aerodynamic interactions between the cyclists and these interactions have been exploited for performance benefits. One such aerodynamic interaction is drafting, where cyclists closely follow each other and experience a reduction in aerodynamic drag. The benefits of drafting are profound with drag reductions as high as 49%. The aerodynamics of drafting have been studied previously using qualitative and quantitative techniques such as wind tunnel test, numerical methods and track testing. However, large discrepancies exist between various studies partly due to the fact that most investigations focus either on flow visualisation or drag measurements, and thus a complete picture is not obtained. The
Ring of
Fire technique is an innovative flow measurement system that provides both flow field information as well as aerodynamic drag force for full-scale on-site transiting cyclists. The
Ring of
Fire technique is used in the current study to investigate the aerodynamics of on-site drafting cyclists in an outdoor environment. The effect of drafting distance and cyclist size on drag reduction are investigated using different configurations of two cyclists in drafting formation. Large-scale time-resolved stereoscopic Particle Image Velocimetry (PIV) is conducted using Helium Filled Soap Bubbles (HFSB) at cycling speeds of 13.3 m/s. Planar pressure fields are reconstructed from velocity data using the 2D pressure Poisson equation (PPE). Modifications and improvements are made to existing data reduction techniques utilised in previous
Ring of
Fire experiments. Qualitative examination of ensemble averaged flow fields is performed for the full wake of an individual cyclist and the near wake of the three cyclists are compared as well. Quantitative analyses of drag area, focusing on variation with distance, sensitivity to wind and statistical uncertainty are conducted. Measurements of individual cyclists show that the size of the cyclist is a qualitative indicator of relative aerodynamic performance between cyclists, provided cycling equipment and skill are reasonably common between them. Statistical uncertainty of the individual measurements are improved from previous outdoor
Ring of
Fire experiments. Flow fields from drafting obtained in-between the cyclists and behind both the cyclists, which are compared with the wake of individual cyclists and the main mechanism of drag reduction for the trailing cyclist is addressed. Quantitative analyses of drag area of the leading, trailing and the two cyclists as a group are performed, with a particular emphasis on drag reduction of the trailing cyclist and its dependence on longitudinal and lateral drafting distances. Anomalies in the drag data indicate towards a complex interaction between the leader wake, phase difference in crank angles and the wake of the trailing…

▼ Many Indigenous nations in Canada are faced with complex issues surrounding proposed development on their lands. There are numerous rights frameworks that support Indigenous Peoples’ inherent rights, which includes their right to free, prior and informed consent (FPIC) in relation to any development that would impact their lands. This case study examined the various perspectives of Matawa First Nations in regard to their experiences of consultation with government and industry. This study was conducted by performing document review and analysis of three focus groups (n=20), a video analysis of the APTN documentary series Ring of Fire and survey distribution and analysis (n=49). Results indicate that Matawa’s experience of the implementation of FPIC fails to comply with Indigenous laws and ideologies and is also not in keeping with the principles of FPIC itself. Government and industry exercise their power by creating biased laws, processes, and spaces for consultation and denying Matawa First Nations any means of participating except by those rules. Matawa First Nations have expressed their willingness to establish genuine relationships with government and industry and work towards sustainable development of their lands. This study ends with a list of recommendations for government and industry to consider in moving forward with consent-seeking in a way that is in keeping with Indigenous perspectives and the principles of FPIC.

▼ Minnesota lowland brush ecosystems provide critical habitat for wide variety of wildlife including over 80 Species of Greatest Conservation Need. These ecosystems depend on fire disturbance to inhibit woody plant encroachment and maintain the herbaceous plant community. Without fire, woody plants become dominant in the overstory, reduce herbaceous cover, and reduce the quality of habitat for wildlife that rely on spatial and structural diversity. Natural resource managers use prescribed burning to decrease woody plant density and enhance the herbaceous plant community in these ecosystems. Currently, the prescribed fire regime in lowland brush ecosystems is largely limited to the spring season, and research in other ecosystems has found that burn season can result in a wide range of impacts to burn severity and both woody and herbaceous plant communities. Understanding the impacts of burn season is critical for natural resource managers to effectively conduct prescribed burns to meet their management objectives. However, little research currently exists on the impacts of fire in lowland brush ecosystems, let alone burn season. The objective of our study was to determine whether season of prescribed burning led to significant differences in burn severity, changes in total woody plant density, changes in density of common woody species, and changes in herbaceous cover. In 2016, we established permanent sample plots at 4 study sites throughout northern Minnesota in order to monitor burn severity and response of vegetation. Each site was broken into 4 burn units including a spring, summer, fall, and a control where no burn was conducted. The results of this study focused on the impacts of burn season on burn severity and the plant community in the first growing season after the burns were conducted, and includes the results of four spring burns, two fall burns, and two summer burns. While we found that burn severity and plant community response differed among burn season treatments, our findings varied by spatial scale. Burns conducted in the spring burned more area those in fall or summer. Given that more area burned in spring compared to fall or summer, we examined the impacts of burn season at different scales to consider broad landscape scale impacts (burn unit scale) and direct fire impacts (plot scale). Burn unit scale included analysis of all permanent sample plots within each burn unit regardless of whether there was evidence of fire at the plot, and at the plot scale we included only on sample plots where evidence of fire was present. Additionally, we broke down the direct fire impacts at the plot scale to look at impacts on common woody plant species and species groups. At the burn unit scale, spring burns were the most severe, resulted in the highest amounts of topkilled woody stems, and the overall greatest reduction in woody plant density even though vigorous resprouting was likely occurring. At the plot scale, burn severity did not differ among burn seasons, but spring burns still resulted in an overall…

▼ Interactions among site conditions, disturbance events, and climate determine the patterns of forest species recruitment and mortality across landscapes. Forests of the American Southwest have undergone significant changes over a century of altered disturbance regimes, human land uses, and changing environmental conditions. This study reconstructs the interactions between
fire, spruce beetle outbreaks, climate, and anthropogenic factors and their influence on the species composition, spatial extent, and structure of four upper elevation forest types. We found that
fire-climate associations changed following
fire exclusion and recent high-severity fires occurred during less severe conditions than in several larger, lower severity fires in the historical record. Contemporary fires are burning with higher severity than similarly-sized historical fires, suggesting a shift toward higher-severity
fire as a result of changes to forest structure and fuels over much of the upper elevation forest. In high elevation forests, the area occupied by Engelmann spruce and corkbark fir doubled in size over the four decades following
fire exclusion. The increase in spruce beetle outbreak size and severity in the 20th century appears to be linked to significant expansion of host extent, accelerated growth of spruce in mixed-conifer forest, and incidence of anomalously warm summer temperatures followed by up to a decade of low precipitation. Trends toward warming, drying conditions are expected to increase the risk of future high-severity outbreaks, especially in locations of recent spruce population expansion. Forest conversion from disturbance-adapted to competition-adapted species following
fire exclusion was a function of site productivity. Species assemblages in the lowest and highest productivity sites were the most stable over the century following
fire exclusion. Frequent low severity fires maintained the stocking of forests in moderate productivity sites below their biological potential, conferring a degree of resistance to drought, insect outbreaks, and high-severity
fire prior to
fire exclusion. Current forests located on moderate productivity sites are now the most vulnerable to drought and future disturbance. Aggressive action to restore historical species composition, stocking and
fire component of these forests may return resilience to this system in the face of projected changes to
fire and climate dynamics.

▼ This multiple manuscript dissertation project contributes to a larger case study research project examining Matawa First Nation experiences of negotiating a proposed mining project known as the “Ring of Fire.” Nine independent First Nations located in the Treaty 9 territory in Northern Ontario, comprise a collective regional organization called Matawa First Nations. These First Nations have a long history of living their Ancestral ways of trapping, fishing, and gathering from the lands. During the early 20th century, the southern Matawa communities began to have contacts with forestry development, but a chromite deposit with an estimated value of 65 billion dollars on Matawa’s traditional territory in 2008 gave rise to interest in mineral extraction across the entire region. In 2012, active communications began with Matawa First Nations to secure access to these lands for development. As a critical Indigenous doctoral student involved in this case study, my interest was to capture first-hand experiences of Matawa Peoples as they contemplate development on their traditional territory. This multiple manuscript dissertation shares three specific areas of interest: the challenge of conducting Indigenous research on lands and culture different than my own, Matawa’s knowledge of Anishnawbe Natural Laws and inherent rights and the communities’ priorities in the face of this proposed development, and lastly the knowledge gained by visiting with Matawa Knowledge Holders to learn the perspectives of leaders and Elders on the proposed development and what they see as future directions for the generations to come.

▼ This thesis has undertaken two main complementary lines of research: firstly, it has looked afresh at the evidence for urban fires in Rome as presented by the written sources and, secondly, it has reimagined the city as an urban
fire regime. Using this new conceptual tool, the fires of Rome are a conduit through which to view the history, architecture, politics, economy, religion, and social and psychological well-being of the city. Each of the 88 fires recorded in the annalistic sources from 460 BC to AD 410 is re-examined. As first principle, the interrogation of the sources begins with the language. By looking at the vocabulary, in both Latin and Greek, of each source from different time periods for every
fire, what has, and what has not, been recorded is identified. Previous translation and interpretation of that information has been challenged in a number of cases. Close reading of the language has also identified a vocabulary of destruction which fits precisely with what modern
fire science tells us about the behaviour of
fire in an urban context. The thesis argues that the Romans knew with great accuracy the predicted effect of
fire on streetscapes, structures and building materials. Systematic close reading of the texts has highlighted a number of other interrelated factors: the cause, extent, location, and the frequency of fires in certain areas, are all collated under each
fire and analysed further in a broad statistical analysis. How much or how little is really known, even in the case of fires where the sources appear to give substantial information, has been demonstrated under each
fire and also represented graphically in case studies. The typology of a
fire regime has been used to fill in the gaps between the recorded fires, and to reimagine fires as a continuum, a lived experience in the city. This has led to challenging assumptions about how flammable Rome actually was, and the extent our own view of fires, and how to deal with them, has coloured our interpretation of fires in Rome. The causes of
fire, efforts to prevent and retard
fire, have all been examined in detail using comparative data from more recently documented fires together with modern research in the field of
fire science. Recent technological studies show that assumptions about the flammability of wooden structures, as well as the effect of
fire on concrete and stone, must be re-evaluated. Evidence is presented that the Romans were acutely conscious of the causes and preventability of fires; they knew how to retard
fire in terms of building materials, construction, legislation, civic responsibility and, of course, prayer. It is also argued that the role of water in
fire-fighting in Rome must be reassessed, particularly in the work of the Vigiles. Our understanding of the Vigiles has been coloured by the modern view of a ?
fire brigade? and this thesis has debated assumptions about their role among the other urban cohorts. Modern research has also been used to challenge the silence of our sources and to glimpse the human experience of…

▼ Predicting the behavior of a
fire which produces spot fires can be very difficult for managers. A simple, deterministic, mechanistic model for predicting the perimeter of a
fire with active spotting will contribute to the current suite of tools used in the field. The model I developed of
fire spread builds upon an established model from biological invasion theory known as the coalescing colony model. The model incorporates other existing, mechanistic
fire behavior models to predict the perimeter of a
fire as it grows by diffusion and coalescence with spot fires ahead of the front. The result of manipulating the biological invasion model is a system integro-differential equations that describe the progression of the main
fire front and are capable of accounting for dispersal variability. My model was verified using a stochastic, computer simulation that supported both the qualitative and quantitative outcomes of the mathematical model. Because of its simplicity, the model can readily be incorporated into existing simulation and model packages.

▼ The success of any organization is dependent, in part, on the quality of its leaders. The fire department is no exception. In fact, one could argue that effective leadership in the fire department has become more critical than ever in today's world. This critical need for an effective fire department dates back to the unprecedented terrorist attacks on September 11, 2001 (9/11; Barg, 2009). On that infamous day, the New York City Fire Department (NYFD) was on the front lines, and over 300 firefighters died. Since then, other terrorist attacks have shattered our quotidian lives: the anthrax threats that occurred shortly after 9/11 in the alter part of 2001, and more recently, the Boston Marathon bombing in April 15, 2013; the Paris terrorist attacks on November 14, 2015; followed close behind by the San Bernardino, CA, shootings on December 2, 2015. We now live in a world where the terrorist organizations of the Islamic State of Iraq and the Levant (ISIS), Al Qaeda, Al Shabaab, and Boko Haram, to name a few, dominate our headlines. Our troubled world has made critical the need for fire departments and emergency responders that are ready to respond at every moment of the day or night. And yet, the only way to ensure that the cadre of firefighters is maximally effective is via strong leadership.; To that end, evaluations on the performance of fire departments have been conducted to ascertain how well fire departments have responded to these emergencies-specifically, what steps were taken and by whom. Clearly, when firefighters are called upon, an error in judgment or poor direction may lead to irretrievable damage to property, and far worse, the loss of human life. In response to the increase in these violent attacks and catastrophic events, strong leadership development programs in the fire service must continue to evolve.; Through interviews with past and current leaders in the fire department, this researcher was able to identify leadership development characteristics specific to fire service leaders. This narrative inquiry was supported by Agyris' Learning Theory with secondary support through Schon's reflective practice theory (Schon, 1989), Kolb's experiential learning cycle (Denton, 2011), and Yukl leadership development (2013) which focus was on the collective aspect of leadership roles, and he defined leadership development as "expanding the collective capacity of organizational members to engage effectively in leadership roles and processes" (Day, 2000, p. 582). Argyris (1993) identified five principles of effective leadership development, while Yukl (2013) emphasized the characteristics of effective leadership, both with respect to the leader, the individuals who report to the leader, and the situation itself. Yukl further contended that effective leadership must include formal training, developmental activities, and self-help.; The researcher interviewed 12 fire department leaders, active or recently retired, from four regions in the United States: northeast, northwest, southeast and southwest. Five…

▼ There is scant information available on the occurrence of fire in the Eastern Tiers of Tasmania. Whole, very large and fire scarred eucalypt cross sections were used as source material for the reconstruction of a fire history for this region. Accurate dating of fire scars in Eucalyptus has been problematic due to the unreliable nature of the annuality of growth rings. Eucalypts have a proclivity for growth anomalies such as false and or missing rings. The annuality of eucalypt tree rings was assessed using dendrochronological techniques on a sub-set each of young trees <140 yrs (n = 15) and old trees > 150 yrs (n = 27). A software program was developed to assist with data capture and analysis. “Detect Rings” identified ring boundaries and measured ring widths from high resolution photographs. However, the seven sampled eucalypt species (E. amygdalina, E. obliqua, E. dalrympleana, E. tenuiramis, E. delegatensis, E. pulchella, E. globulus), were not amenable to withinor between-tree cross-dating.
Multiple radial ring counts from 104 large trees (photographs: n = 27, in situ: n = 77) were aggregated and tested for reliability with a mean error margin of ±7 rings being calculated where tree age was estimated at > 200 years. Additional sources of error were progressively eliminated. The integrity of fire scar capture from thirteen sites, each with variable sample numbers, was addressed by the development and application of a sample size adjustment procedure analogous to the bootstrap. This process indicated that 9-10 sample trees per site were sufficient to detect a high proportion of fire events large enough to generate injurious fire scars. There was no effect on fire scar distribution resulting from tree age, species composition, landscape position, bark thickness, diameter over bark, slope or elevation. The age of the oldest sample tree was estimated to be ~570 years.
The sample size adjustment procedure was used to derive the mean decadal fire years for each tree at each site. Temporal and spatial patterns were then discerned. Temporal patterns were related to variation in annual rainfall. Approximately 29% of fire years which occurred across three or more sites were related to years of low rainfall indicating a relationship between low rainfall and widespread fires.
A composite fire scar chronology was developed 1740 – 2004 from which distinctly different periods of fire years were defined. Fire years were recorded as mean fire years per decade, per period, thus: 0.7 in the Aboriginal era 1740 – 1820, 0.4 in the Transitional era 1820 – 1850, 1 in the 2nd European era 1850 – 1910, 1.5 in the 3rd European era 1910 – 1990, and 0.7 in the Current or 4th European era 1990 – 2004. Between-decade fire scar variability was highest in the Aboriginal era. The incidence of fire scars massively increased across most sites from the 1850s and continued at high levels until the late 1980s, although a reduced number of fire scars were recorded in the first decade of the 20th C. Occurrence of fire scars in the most recent…

▼ An optical vortex is characterized by a dark core of destructive interference in a light beam. One of the methods commonly employed to create an optical vortex is by using a computer-generated hologram. A vortex hologram pattern is computed from the interference pattern between a reference plane wave and a vortex wave, resulting in a forked grating pattern. In astronomy, an optical vortex coronagraph is one of the most promising high contrast imaging techniques for the direct imaging of extra-solar planets.
Direct imaging of extra-solar planets is a challenging task since the brightness of the parent star is extremely high compared to its orbiting planets. The on-axis light from the parent star gets diffracted in the coronagraph, forming a "
ring of
fire" pattern, whereas the slightly off-axis light from the planet remains intact. Lyot stop can then be used to block the
ring of
fire pattern, thus allowing only the planetary light to get through to the imaging camera. Contrast enhancements of 106 or more are possible, provided the vortex lens (spiral phase plate) has exceptional optical quality.
By using a vortex hologram with a 4 µm pitch, and an f/300 focusing lens, we were able to demonstrate the creation of a "
ring of
fire" using a white light emitting diode as a source. A dispersion compensating linear diffraction grating of 4 µm pitch was used to bring the rings together to form a single white light
ring of
fire. To our knowledge, this is the first time a vortex hologram based OVC has been demonstrated, resulting in a well-formed white light
ring of
fire. Experimental results show measured power contrast of 1/515 when HeNe laser source was used as a light source and 1/77 when using a white light emitting diode.

▼ The Ring of Fire is a mineral resource-rich area of approximately 5,120 km2 located in the James Bay Lowlands region of Northern Ontario, about 500 kilometers northeast of Thunder Bay. The Ontario Ministry of Northern Development and Mines generously estimates the Ring of Fire to contain $60 billion worth of minerals. The Ontario government and industry envision that the Ring of Fire could be a region with multi-generational mining activity. However, the area has no historical or current industrial activity, and no road or rail access. Also, mining proposals in this resource rich, inaccessible and ecologically sensitive area have generated significant controversy and conflict because the potential for wealth generation is accompanied by the potential for significant and possibly serious net negative lasting cumulative effects and poorly distributed benefits and risks, particularly for First Nations communities, including Eabametoong First Nation.
One major method of anticipating and planning for the effects of industrial development is environmental assessment. However, my research finds that traditional assessment methods are woefully inadequate for considering the potential regional impacts of the Ring of Fire on the land, waters and communities. Conventional assessment is insufficient to identify and address cumulative effects, and it does not provide an adequate base for determining whether proposed developments are likely contribute to lasting well-being and sustainability. These inadequacies are particularly challenging for the most vulnerable communities, where these deficiencies threaten to perpetuate long standing colonialism and conflict.
The findings suggest that Canadian resource development processes at large would be considerably assisted if anticipatory assessment and decision making focused on the actual (in this case regional) scale of the potential effects, examined the potential for lasting overall gains, and integrated fair process with equitable relationships and substantive consideration of context-dependent sustainability. In this research, assessment criteria were developed in collaboration with Eabametoong First Nation for application in the Ring of Fire utilizing generic sustainability criteria, existing academic data and Eabametoong’s own perspectives. Central to the resulting assessment framework is the need to foster consent, respect indigenous rights and utilize indigenous knowledge. My findings indicate that much of the mainstream discussion on the Ring of Fire has framed the key debates as economy versus the environment, and have situated the current project-centred environmental assessment processes as a venue for battles over these priorities. A broader and more positive approach, using regional strategic assessments to find pathways to lasting overall benefits for the Ring of Fire communities and area, is not yet on the agenda. This research found that a more comprehensive package that utilizes assessment not simply as a box check, but as a means to enhance the lives of…

▼ The Ontario Ring of Fire is a potential mining project that is located in the far north of the province, within Matawa First Nations homelands and traditional territory. My thesis examines how the Ring of Fire is continually shaped by the conflicting discourses that surround it. To study this, I observed how the Ring of Fire was situated within five mining events. Events were held by different organizations, for different audiences, and had different purposes; varying widely in size and scale. While some actors deployed spectacularly streamlined messages to entice investors and propel the project towards a predetermined future, others unraveled these messages by exploring the complications and revealing a wider range of possibilities. However, events largely acted as silos, and the observed encounters across difference mostly took place through the media. This allowed some organizations that were represented at multiple events to significantly shift their message between audiences. My hope is that this research provides a historical account of how the Ring of Fire was (or wasn’t) conjured into being during a time of widespread political change. It may also contribute to the field of event anthropology, and it may provide an account of the changing face of CSR.

▼ The Black Label, Black Thor and Big Daddy chromite deposits are a series of chromitite layers that are hosted by the 2734.5 +/-1.0 Ma ‘Ring of Fire’ Intrusion in the McFaulds Lake greenstone belt of Northern Ontario. Over 4200 electron microprobe analyses and 142 laser ablation ICP-MS analyses were performed on chromite and record individual fractionation sequences of chromitite below the metre scale. In comparing results, the dunite-hosted Black Thor chromites are higher grade with 53 to 49 wt. % Cr2O3, more primitive than Black Label chromites at 50 to 46 wt. % Cr2O3. Heterogeneous growth of orthopyroxene oikocrysts in Black Label chromitite accounts for increased silicate content. Massive chromitite at Big Daddy shows remarkable homogeneity at 50 to 51 wt. % Cr2O3. The homogeneity of the massive ore is attributed to development of chromitite layers by continuous magma pooling. A strong linear regression of increasing Cr2O3 with MgO from disseminated to massive chromite at all deposits indicates the primary chromite compositions are magmatic. Elemental variation in the chromites include decreasing Cr, increasing Fe, slightly decreasing Al and decreasing Mg due to differentiation. Near constant low-Al compositions are characteristic of komatiitic chromite. Laser ablation results show trends of depletion in Ti, V, Zn, Mn and Co, but enrichment in Ni and Sc, consistent with fractionation of chromitite. The chromitites contain mineral inclusions of pyroxene, igneous amphibole, and phlogopite that have very magnesian contents suggesting a source in the ultramafic magma. The host dunite and pyroxenite have negative Nb-Ta and Zr-Hf anomalies that signify an inherent contamination of ultramafic magma by TTG crust. The Ring of Fire Intrusion has been autohydrated, causing pervasive serpentinization and tremolitization of host dunite and pyroxenite. Secondary ferrichromite with higher wt. % FeOT and Cr2O3 forms as rims on primary chromites, thereby enriching the Cr content of the ore. The rims of primary chromites are leached of Mg and Al leaving high Cr and Fe. The released Mg and Al forms magnesian clinochlore that contains up to 9 wt. % Cr2O3.

Biomonitoring under changing climate conditions: assessing seasonal variability of benthic macroinvertebrate communities and stream characteristics in two ecozones in Northern Ontario, Canada.

▼ The vast “Ring of Fire” region, at the interface of the Boreal Shield and Hudson Plains ecozones in the far north of Ontario, Canada, is considered to be one of the most promising mineral exploration areas in Ontario in almost a century. The region is undeveloped and remote, accessible only by air, water or winter road. Multiple stresses to the natural ecosystems are anticipated with mining development, in a time of climate change which is predicted to significantly impact hydrological and temperature regimes (intensified spring freshet, more high discharge events, warmer temperatures for longer). Preserving and protecting the aquatic ecosystems in this pristine region will require effective baseline environmental monitoring in advance of development. Quantifying seasonal variation of habitat characteristics and benthic macroinvertebrate (BMI) communities, and assessing the seasonal difference between ecozones are considered key challenges in designing effective monitoring programs. In this study, I examined seasonal variability in habitat characteristics and BMI communities by sampling 43 stream sites distributed across the two ecozones. In 2015 each site was sampled three times during the open water season: post-freshet, mid-summer and fall. BMI communities varied among sampling seasons, but less variation was observed between the post-freshet and summer sampling periods than either of these compared to the fall. Ordination analyses of BMI communities identified to the family level indicated that sites from the same sampling season were more likely to group together. Water temperature, stream velocity and canopy coverage were the key factors associated with seasonal differences in benthic macroinvertebrates. Differences in location of the sampling sites across the two ecozones did not significantly impact seasonal variability, but differences may have been constrained by the common habitat features used because of the sampling protocol. Conducting sampling during the post-freshet or summer seasons is recommended for future stream bioassessments to reduce the influence of seasonal variability and thus ensure comparability over time.

▼ Fires within the built environment are a fact of life and through design and the application of the building regulations and design codes, the risk of fire to the building occupants can be minimised. However, the building regulations within the UK do not deal with property protection and focus solely on the safety of the building occupants. This research details the statistical analysis of the UK Fire and Rescue Service and the Fire Protection Association's fire incident databases to create a loss model framework, allowing the designers of a buildings fire safety systems to conduct a cost benefit analysis on installing additional fire protection solely for property protection. It finds that statistical analysis of the FDR 1 incident database highlights the data collection methods of the Fire and Rescue Service ideally need to be changed to allow further risk analysis on the UK building stock, that the statistics highlight that the incidents affecting the size of a fire are the time from ignition to discovery and the presence of dangerous materials, that sprinkler activations may not be as high as made out by sprinkler groups and that the activation of an alarm system gives a smaller size fire. The original contribution to knowledge that this PhD makes is to analyse the FDR 1 database to try and create a loss model, using data from both the Fire Protection Association and the Fire and Rescue Service.

▼ The set of all positive integers less than n and relatively prime to n with multiplication mod n is a group denoted U(n). These groups are useful in algebra, number theory and computer science. We are interested in studying the structure of certain subgroups of U(n). As part of their 1980’s paper titled Factoring Groups of Integers Modulo n Gallian and Rusin determined the structure of U(n) and U_s (n) for n=st where gcd(s,t)=1 and U_s (n)={x∈U(n)┤|x (mod s)=1}. We extend this definition to U_k (n) where k is any positive integer and not necessarily a divisor of n. Moreover for a subgroup H of U(n) and an integer k we define: U_(k,H) (n)={x∈U(n)┤|x (mod k)∈H}. We find the structure of these subgroups and the factor group U(n)/U_k (n) in terms of an external direct product of cyclic groups. Our methods also determine group elements of U(n) that form a subgroup with a desired structure. We then shift our attention to the class of subgroups defined as: U(n)^((k))={x^k ┤| x∈U(n)}. We fully classify subgroups of this form and their factor groups. They are useful in finding Sylow p-subgroups of U(n) groups. We also prove some general results about U(n) groups including when the order of U(n) is a power of a prime. Finally we give a simple proof that every finite Abelian group is isomorphic to a subgroup of a U-group.

(more)
▼ With the large scale of anticipated mining development in the Ring of Fire (ROF) area and the potential for other future industrial developments and rapid climate change in the north, there is a great need for basic limnological data for lakes in the Far North of Ontario. To address this need, water chemistry and crustacean zooplankton surveys of northern Ontario lakes were conducted to examine regional differences between lakes of the Precambrian Shield and Hudson Bay Lowlands, focusing on the ROF area, which straddles the boundary between these physiographic regions. Lakes of the ROF area displayed highly variable water chemistry, a product of the extensive peatland landscape with its mix of bog and fen watersheds. This peat cover appears to decouple, to varying degrees, the lakes from the influences of bedrock and surficial geology and is a source of complex organic matter and acids. Shield lakes in the western portion of our study area had base cation concentrations (Ca, Mg) markedly higher than those of previously studied Shield lakes south of 50°N, likely due to the abundance of lacustrine and glacial end-moraine deposits throughout western Ontario north of 50°N. The zooplankton species collected during this survey were generally similar to those reported for lakes further south on the Precambrian Shield. Zooplankton assemblages were strongly influenced by lake morphometry, with higher species richness in the deeper Shield lakes than in the shallower Lowlands lakes which would appear to offer less niche space for coexistence of species.

▼ We study ideals of pointfree function rings. In particular, we study the lattices of z-ideals
and d-ideals of the
ring RL of continuous real-valued functions on a completely regular
frame L. We show that the lattice of z-ideals is a coherently normal Yosida frame; and
the lattice of d-ideals is a coherently normal frame. The lattice of z-ideals is demonstrated
to be
atly projectable if and only if the
ring RL is feebly Baer. On the other hand, the
frame of d-ideals is projectable precisely when the frame is cozero-complemented.
These ideals give rise to two functors as follows: Sending a frame to the lattice of
these ideals is a functorial assignment. We construct a natural transformation between the
functors that arise from these assignments. We show that, for a certain collection of frame
maps, the functor associated with z-ideals preserves and re
ects the property of having a
left adjoint.
A
ring is called a UMP-
ring if every maximal ideal in it is the union of the minimal
prime ideals it contains. In the penultimate chapter we give several characterisations for
the
ring RL to be a UMP-
ring. We observe, in passing, that if a UMP
ring is a Q-algebra,
then each of its ideals when viewed as a
ring in its own right is a UMP-
ring. An example
is provided to show that the converse fails.
Finally, piggybacking on results in classical rings of continuous functions, we show that,
exactly as in C(X), nth roots exist in RL. This is a consequence of an earlier proposition
that every reduced f-
ring with bounded inversion is the
ring of fractions of its bounded
part relative to those elements in the bounded part which are units in the bigger
ring. We
close with a result showing that the frame of open sets of the structure space of RL is isomorphic to L.

▼ The density of public communications in Brno has acquired the character of metropolis, which, however, is nowadays asking for help in further development. The historic centre is fighting with dilapidation or with unused space of suburban districts. Behind all this I see the problem of urbanity, of propinquity. The resulting built-up area in the related locality complements to historical centre, to circuit and with its sequel of moves seeks inspiration in the development of nearby suburban districts. The priority of walk should be re-creation of network, sort of unity of space.

▼ Mitt syfte med denna studie av Häckelsängsringen är att ta reda på om den verkligen är från vikingatiden samt om den har haft en eds-, rit- eller kultfunktion? Finns det någon vikingatida kult i området som kan komma ifråga när det gäller denna ”mystiska ring”? Till min hjälp har jag tagit litteratur som talar om ringar och eder till exempel de Isländska eddorna. För att se om det finns en vikingatida kult i området har jag besökt Hamrånge socken, både själv och tillsammans med arkeologer. Jag har studerat länsmuseets faktarum och fornminnesregistret. I fornminnesregistret har jag hittat platser såsom en reliklund med mycket gamla lindar, en tänkbar offerkälla, en stenlagd cirkel som kan vara en tingsring samt att i närheten finns ett område som på gamla kartor kallas Lundåker, en tydlig odling av hassel. Allt detta sammantaget tyder på en vikingakult i området. Järnringen har krokar på insidan och dessa har jag försökt att tolka. Det jag kommer fram till är att dessa krokar kan symbolisera olika saker beroende på vad man skulle ha den till för stunden. Det finns ett tydligt mönster som visar ett vikingaskepp mellan två krokar. Krokarna i sig själv anser jag symboliserar eldstål och dessa tillskriver jag vikingaguden Tor.

▼ Fire is a dominant form of disturbance in the American west, and is a primary management concern because of its threat to natural resources and human development. Research on
fire history of the Great Basin is lacking. Here I summarize the results of a
fire history study in the Clover Mountains of Lincoln County, Nevada. Using
fire scars from ponderosa pine trees I reconstructed
fire history back to 1785 and examined
fire frequency,
fire extent and
fire severity through time. Historically, the Clover Mountains were dominated by frequent (<10 year mean return interval), low severity fires. Fires were often large, with half the
fire events scarring greater than 10% of recorder trees. Visual and ecological evidence on the landscape suggests the 1946
fire may have been a high severity event. Fires have not been recorded in sampled trees since 1946. Human
fire suppression activities may be the cause of this
fire gap in the last 60 years, which suggests the Clover Mountains are moving outside their historic range of variability.

▼ Basalt and plant fibres are increasingly being used as eco-friendly replacements to E-glass fibres for the reinforcement in polymer composites used by the automotive and construction industries. The aim of this PhD is to investigate the structural properties of basalt fibre polymer composites when exposed to thermally demanding environments such as those experienced during fire exposure or thermal recycling. This PhD project also aims to understand the structural performance of plant fibre composites when exposed to fire. The thermal, physical and mechanical processes that influence the softening and failure of basalt and plant fibre composites under the combined effects of fire and mechanical loading are determined experimentally and analytically. The reduction to the mechanical properties and the strength loss mechanisms of thermally recycled basalt fibres are also investigated.

▼ Three structural materials commonly used in modern aircraft are aluminium alloys, carbon fibre-epoxy laminates and fibre metal laminates. The aim of this PhD project is to determine the softening behaviour of these materials when exposed to combined mechanical loading and fire. The specific materials studied are aluminium alloys (AA2024 and AA7075), quasi-isotropic carbon-epoxy composites, and a fibre metal laminate (GLARE). The thermal, physical and mechanical processes controlling the softening and failure of the materials under structural loading and one-sided heating by fire are determined. The two important structural loading cases of tension and compression are studied for different radiant heat flux conditions representative of fires having different flame temperatures. The term ‘fire’ is used in this PhD to describe the radiant heat which is emitted by fire and then absorbed by materials. The term ‘fire’ does not describe the flaming process itself nor direct flame impingement on the test materials. Due to the test methods used in this PhD project, the materials were not exposed to an actual fire, but were exposed to heat fluxes representative of the heat radiated by a controlled flame/fire. This approach is similar to other testing methods used to measure the fire properties of composites and other combustible materials, such as the cone calorimeter which is used to measure the fire reaction properties (e.g. time-to-ignition, heat release rate) but does not use an actual fire in the test. Presented in the PhD thesis is a comprehensive and critical review of published research on the thermal-mechanical properties of the aerospace structural materials. A review of research into the fire structural and fire reaction properties of polymer matrix composites is also presented. Based on the existing research, gaps are identified in the knowledge of the thermal response and structural survivability of aerospace-grade materials when exposed to combined loading and fire exposure as well as the residual strength properties of the materials after fire exposure. This PhD aims to address these research gaps. The mechanical properties including creep as well as the thermal and physical responses of aircraft-grade aluminium alloys under fire conditions are experimentally investigated. The structural performance of AA2024 and AA7075 alloys under tension and compression loads is analysed using a thermal-mechanical finite element model and experimentally evaluated using fire-under-load tests. When exposed to the same radiant heat flux, both alloys reach the same front surface temperature, however the heat transfer through-the-thickness is more rapid for the 7xxx alloy due to its higher thermal conductivity. The structural survivability of the 7xxx alloy under tension or compression loading is inferior to the 2xxx alloy due to its faster heat transfer rate which accelerates softening. The effects of elastic, plastic, creep and other factors on the softening and weakening of…

▼ This thesis is structured into two parts. In the first two chapters, we prove the non commutative version of the Arithmetic Geometric Mean (AGM) inequality (this is a joint work with Mingyue Zhao and Maruis Junge). We start Chapter 2 by giving some background about the partition and M{ö}bius function. We then prove the two main theorems: The AGM inequality for the norm and for the order. In Chapter 3, we provide some applications from random matrices such as Wishart random matrices, vector-valued moments of convex bodies, and freely independent operators.
The second part is about a ternary
ring of operators (TRO). After giving a quick survey for the work of Todorov on the operator space version of Zettl's decomposition theorem, we introduce crossed products of ternary
ring of operators (the full crossed product and the reduced crossed product). We also prove that V\rtimes
αVG as the off-diagonal corner of the C^*-algebra A(V)\rtimes
αA(V)G. Equivalently, we have the *-isomorphism between the two linking C^*-algebras, i.e. A(V\rtimes
αVG)=A(V)\rtimes
αA(V)G. By using this identity, we obtain that if the group G is amenable, some local properties for TRO's preserve with the crossed product. We also provide a counter example which shows that if the linking C^*-algebras A(V) and A(W) are *-isomorphic or if their diagonal components are *-isomorphic, then their TRO's are not isomorphic. Similar example will be applied for W^*-TRO's.

eThekwini Fire and Emergency Services currently uses a repurposed structure to train their firefighters. This study identifies fire related hazards for trainee firefighters when using the ground and first floor of the existing structure. The purpose is to prevent shortcomings being repeated in the design of future firefighter training structures.
The fire related hazards have been identified by using Computational Fluid Dynamics (CFD) to simulate fires in the existing structure. The fundamentals of CFD, as well as the selected CFD based fire model, have been summarized. CFD is selected due to its flexibility, accuracy, and cost effectiveness [1]. The Fire Dynamics Simulator (FDS) is the selected CFD based fire model as it has been extensively validated in the past decade [2], which is an important factor should the CFD code claim any credibility [3]. It was developed by the National Institute of Standards and Technology (NIST) to model fire driven fluid flow. It does this by numerically solving a form of the Navier Stokes equations appropriate for thermally driven low Mach flow [4].
Appropriate inputs required for FDS were investigated specifically for live fire training structures. A unique heat release rate (HRR) was investigated and subsequently proposed for a fire on both the ground floor and first floor. The HRR was assessed to find a rate that will be safe from inducing ventilation-controlled conditions and therefore preventing the occurrence of an explosive backdraught. This was investigated by monitoring the effect of the existing structure on a t-squared fire. A t-squared fire uses a selected growth coefficient to estimate the fire’s HRR when the data on the actual fire is not available. Also, the suitability of selecting the emissivity of soot for surfaces was investigated. This was done because it is expected that there would be residual soot deposits in the existing structure. The investigation used the soot modelling capabilities of FDS. This identified the soot density on exposed surfaces and provided an indication on the number of fires required to cover the majority of the exposed surfaces with soot.
The simulations performed in this study were within the required validation range. This included using a selected numerical grid size that was within the validation range for the plume resolution index. There is a range of grid sizes that are valid for the plume resolution index and so to assist in the selection of a suitable grid size from the range of valid grid sizes, the implications of time constraints to complete a simulation were investigated. The investigation compared the accuracy of FDS results when having to restart the simulation multiple times due to limited computer access time, with the accuracy of FDS when using a coarser grid.
From the fire induced environment, the heat flux and gas temperature were estimated to assess…
