    With the recent development of high-end computation technology, it is feasible to use complex numerical modeling technique such as synthetic rock mass (SRM) modeling for the characterization of mechanical properties of rock mass. However, the SRM modeling approaches that have been used to date such as the ones based on bonded particle and bonded blocks cannot properly incorporate realistic discontinuity surface geometry (waviness and roughness) into the numerical model and discontinuities are often simplified as having planar surfaces. Models with simplified planar discontinuity surfaces do not represent the true geometry and physics of the natural discontinuities which raises the question on the reliability of the geotechnical parameters resulting from these models. It is widely known that the inherent surface roughness significantly influences the shear strength and stiffness of a non-planar discontinuity. The goal of this thesis is to develop numerical models that can incorporate these natural undulating discontinuities for the determination of reliable estimates of strength and deformation properties of jointed rock masses. Three-dimensional lattice-spring-based synthetic rock mass (LS-SRM) models are generated by incorporating both planar and non-planar discontinuities to simulate the mechanical behaviors of both laboratory-scale jointed rock and mine-scale jointed rock masses. A calibration methodology is established by means of extensive sensitivity analysis of lattice model parameters. Studies are also conducted to understand the crack evolution mechanism (initiation and propagation) in precracked marbles with both planar and non-planar cracks. Influences of joint properties (orientation, intensity, persistence, and roughness) on the strength and deformability of jointed rock under compression are also investigated. Influence of rock mass scale on the strength and deformation modulus is investigated to determine the representative elementary volume (REV) of the rock mass. Using the REV sized rock mass, the influence of discontinuity intensity and confining pressure on the mechanical properties (strength & deformability) of jointed rock masses are also investigated. In addition, the influence of the pre-existing natural discontinuity of different configurations (waviness, intensity, size) and in-situ stress on slope stability and deformability of an open pit mine are investigated. Complex crack propagation mechanism is observed in the laboratory-scale pre-cracked rocks with non-planar cracks under compression. There is an increase in the strength and deformation modulus for the laboratory-scale jointed rock models with non-planar discontinuities, lower discontinuity intensity, and lower discontinuity persistence. Peak strength and deformation modulus of the rock mass decreases with the increase of discontinuity intensity. Peak strength of the rock mass increases with the increase of confining pressure. Slopes excavated in the rock mass with non-planar discontinuities are found to be more stable than the slopes excavated in the rock mass with planar discontinuities. Similarly, slopes excavated in the rock mass with larger discontinuity size and higher discontinuity intensity are less stable than the ones excavated in the rock mass with smaller discontinuity size and lower discontinuity intensity. It is also found that the slopes exhibited localized instabilities under the influence of high in-situ stress. The findings of this research aid in better characterization of the mechanical behavior The findings of this research aid in better characterization of the mechanical behavior of jointed rock mass and provide more reliable estimates of geotechnical design parameters

    The downsizing Catholic Church: learning from Borromini’s counter-reformation architecture

    Get PDF
    This thesis examines the work of Baroque architect Francesco Borromini toward an architectural response to the downsizing Catholic Church in North America. The century following the Protestant Reformation offered similar challenges to the Church. In response to the Reformation, numerous Counter-Reformation measures were employed to revive the Catholic Church. Architecture that conveyed Catholic theology was considered a valuable tool in restoring the Church. Selected buildings designed by architect Francesco Borromini are examined for insights into design techniques and strategies explored to synthesize Catholic theology and architecture. The Sant’Ivo alla Sapienza and San Carlo alle Quattro Fontane churches in Rome are studied using research-creation methods that employ architectural drawing as an investigative tool to discover the theological significance of the buildings. The architectural design proposal explores conclusions drawn from research and applies the research findings toward the design of small contemporary Catholic Church in Orangeville, Ontario

    Motivational interviewing in intake/crisis intervention

    Get PDF
    This Advance Practicum report examines my experiences in further developing my clinical skills, primarily in the area of Motivational Interviewing (MI) techniques, while completing an Advanced Practicum with the Health Sciences North (HSN) Mental Health and Addictions Program (MHAP) as the intake/crisis worker. The intake/crisis program of Manitoulin Island is designed to address the mental health and addiction crisis needs of clients over sixteen years of age who present in psychological distress at either of the emergency departments of the Manitoulin Health Centre (MHC). My goals within this practicum were to enhance my social work practice skills by facilitating motivational interviewing techniques during intake and crisis interventions, working as part of multidisciplinary team, attending clinical supervision, and diligently critiquing my social work practice with reflective MI log journals and a supervision journal. Throughout this report, I reflect on the critical analysis of the practicum as I focus on two distinct observations and insights within my MI experiences: 1) How can MI enhance treatment compliance? and 2) What challenges might MI methods of interviewing present? Throughout the process of completing this practicum and report, I reflected on the effective use of MI with the different populations that presented, increased my MI skill set, and developed increased self-awareness through reflective social work practise.Master of Social Work (MSW

    The effects of natural magnetic fields on biological systems : evidence from planaria, sunflower seeds and breast cancer cells

    No full text
    Natural magnetic fields include the Earth’s magnetic field and biomagnetic fields produced by living organisms. Earth has a static magnetic field whose intensity is constantly fluctuating and has deviations called geomagnetic storms. In multiple experiments, we found that geomagnetic storms that occurred either on the same day as the experiment, or four days before the experiment had a significant impact on the subsequent behaviour of planaria and photon emissions of germinating sunflower seeds. However, the effects were most evident in only a subset of their populations. Consistent with this idea, a small proportion of planaria seemed able to detect the presence of a weak, patterned electric field in a maze. We also found that when humans practised healing intentionality on breast cancer cultures, they had a subtle influence on the photon emission from the cells. These results demonstrate the effectiveness of natural magnetic fields even if their influences evade our awareness

    Provenance and depositional age of the Cryogenian ‘grand conglomérat’, host of the Kamoa Cu-deposit, Democratic Republic of Congo

    The Kamoa copper deposit (759 Mt, 2.67% Cu at 1% cut-off) is one of the largest copper deposits in the central African copperbelt. Mineralisation at Kamoa is hosted by the Cryogenian ‘grand conglomérat’, which was deposited in an intracratonic rift and its sub- basins associated with the break-up of Rodinia, and is equated to the ‘Sturtian’ glaciation, the oldest of the Neoproterozoic glacial events. Using detrital zircon geochronology, the provenance of synglacial and underlying pre-glacial units is compared, to evaluate the temporal dynamics of the sediment supply at Kamoa. The detrital zircon age distributions suggest that the ‘grand conglomérat’ was derived from locally exposed basement of the Mesoproterozoic Kibaran Supergroup and from significant recycling of underlying pre-glacial units, with minor contributions from distal, primary source areas. The stratigraphic differences in the distribution of zircon age populations of the strata at Kamoa may reflect changes in glacial dynamics or of rifting during deposition of the ‘grand conglomérat’. A Neoproterozoic zircon age population ~700 Ma is probably derived from rift-related volcanic rocks and is significant because it repositions the timing of mid-Neoproterozoic rifting in the Katangan basin and the maximum depositional age of the ‘grand conglomérat’. The new age constraints suggest that the midNeoproterozoic ‘Sturtian’ glaciation was globally diachronous

    Drawing anime as a cross-cultural therapy & rebellion for young girls in foster care

    Adolescent girls in the foster care system are sometimes misunderstood, mistreated and negatively labelled. Along with changes in governmental social policies, the female foster demographic is at higher risk of becoming involved in the judicial system. Programs such as The Holistic Arts Based Program (HAP) aim to provide an environment that nurtures creativity and teaches resilience to young foster children/adolescents who have learning disabilities and have faced loss, neglect and trauma. This study focuses on a particular group of adolescent girls from the foster care system who attended HAP for 24 weeks to seek insight into their use of anime as a therapeutic process. Through textual analysis and psychoanalysis, I trace the difference between the anime inspired art produced in past HAP sessions compared to the art from the anime activity. Anime allows for a therapeutic revision of their past and engages an active identification process. The girls consciously use anime to oppose authority figures and structures that rejected them. The cross-cultural use of anime also serves as a vessel for defiance, creativity and therapy

    Today, Brampton suffers from a negative image. Especially Brampton’s majority of working-class immigrants who are experiencing socio-economic and territorial exclusion. The exploitation by the media has also had an effect on the negative identity construction. With a population close to 600,000 people, Brampton has many people to serve. Of the 600,000 there are 234 different ethnic groups speaking 115 different languages. Brampton’s First Cultural Master Plan is supposed to set the strategic direction for arts and culture in the city. My critique is that it misses the point. The under-presented Brampton youth (who are mostly black and brown) to me is Brampton’s heart and soul - the youthfulness, cultural diversity and entrepreneurial energy ought to be the most important resource for the city. This said, Brampton’s focus on business and economic development is but one of many examples of urban design that neglects the ethnicity and diversity of immigrant Canada. Brampton’s identity is growing, maturing, diversifying and transforming. As the city grows and matures, so are the residents. We live in a world where everything and everyone is being constantly classified into categories: religion, gender, ethnicity and race. The malicious use of racial categories has resulted in violence and racism. And most of the violence has been directed at First Nations Peoples, Black Canadians and immigrants from non-European countries. I argue that Brampton will continue to face racial tension unless something is done to the negative representation and misrepresentation of cultural diversity. I think the energy ought to focus on young people as they themselves are defining their identities and wanting to make Brampton their own. My thesis, thus, begins with the question: How can architecture bring communities together to co-exist while acting as a setting for self-identity formation, especially for youth in the cit

    Biometeorology: review and analysis with regard to traumatic brain Injury acquisition in professional football, as well as traditional and digital economic markets

    This research explores Biometeorology, which is the relationship between the environment and human behavior. Previous research has indicated that meteorological events such as lunar cycles, solar activity, temperature, and humidity have been extensively documented to affect human psychophysiology through systemic variation. The purpose of this document is to explore the effects of environmental factors on typical everyday aggregate behaviors in distinct, unique and separate investigations that relate to participation in sporting events and economic activities in order to determine if these naturally occurring influences are genuine. For example, local weather related and extra-terrestrial phenomena were collected during timestamped Traumatic Brain Injury (TBI) acquisition in the National Football league (NFL) for 645 concussed players from 2012-2015. Components of the Earth’s geomagnetic field were also documented in relation to global search tendencies for highly emotional states in addition to stock market indices. Furthermore, solar and lunar cycles were recorded during the monumental rise in the cryptocurrency market in order to identify if these cyclical background patterns systemically altered interest in Bitcoin (BTC) and Ethereum (ETH) or influenced their price index in-and-of-itself. The results indicate that intrinsic capacities of the game of football inherently impacted injury severity and return to play considerations. TBI’s did however, vary as a function of geo-coordination and were most pronounced in the Northwest U.S. Injury severity was also found to be greatest during increased geomagnetic intensities. Lunar contributions also appeared to play a central role in injury acquisition insofar as TBI player height weight and injury severity were predicted by solar and geomagnetic variables of interest during the full moon. Aggregate search behavior on the Internet of Things (IoT) was found to correlate with magnetic variability, geomagnetic intensity as well as Dow Jones price movement and trading volume. Finally, traditional technical analysis indicators closely followed cryptocurrency price. However, Bitcoins Aroon up and down was found to cycle with the Moon, while Ethereum’s Heiken Ashi displayed a relationship with the Sun. Internet interest in Ethereum was found to have significant associations with the Earth’s geomagnetic field, the Sun and the Moon which was enhanced during specific alignments of these heavenly bodies. In summary, seemingly random events and aggregate group behaviors are intimately associated with external interconnected dynamics

    Understanding women athlete concussion in socio-cultural context: a media analysis of Eugenie Bouchard’s concussion

    No full text
    The purpose of the present study was to explore the news media’s portrayal of one elite Canadian athlete, tennis player Eugenie Bouchard, and her performance decline after sustaining a concussion outside of sport. An ethnographic content analysis was used to examine news media reports of prior to, and after the concussion. An overarching theme of ‘performance decline beyond tennis’ was identified in the pre- and post-concussion North American media articles. These results show the value of studying one media incident focusing on a woman athlete, highlighting the impact of the concussion within and outside of tennis. The present study of Bouchard’s career adds to sport psychology injury literature as it demonstrated the inconceivable resiliency and mental toughness an athlete had to face during recovery and return-to-play, inconsistency due to coaching changes, an inability to recover from injuries, and a decline in rankings, all caused by confidence issues
