description: GAIA will provide observations of some multiple asteroid and dwarf systems. These observations are a way to determine and improve the quantification of dynamical parameters, such as the masses and the gravity fields, in these multiple systems. Here we investigate this problem in the cases of Pluto's and Eugenia's system. We simulate observations reproducing an approximate planning of the GAIA observations for both systems, as well as the New Horizons observations of Pluto. We have developed a numerical model reproducing the specific behavior of multiple asteroid system around the Sun and fit it to the simulated observations using least-square method, giving the uncertainties on the fitted parameters. We found that GAIA will improve significantly the precision of Pluto's and Charon's mass, as well as Petit Prince's orbital elements and Eugenia's polar oblateness.

description: The gasification of carbonaceous feedstocks is one method of producing syngas; however, the impurities present in the feedstock require a purification of the syngas prior to the ultimate use, with sub-ppm levels of H2S required. Significant efficiency gains are obtained by performing this gas cleaning step at temperatures between the gasification temperature and the ultimate application temperature (500 - 1200 K). In this thesis, the desulfurization performance of La/γ-Al2O3 is investigated for the removal of 100 ppm H2S in H2. Supporting La2O3 on γ-Al2O3 has yielded a highly dispersed La2O3 phase. Due to the complications of H2S, CO2 was used as a probe molecule for characterization. At higher lanthanum weight loadings, CO2 adsorbed on La2O3 sites was observable in DRIFTS spectra. Also, volumetric chemisorption and TPD data indicate an increased capacity for CO2 adsorption, due to La2O3. The volumetric chemisorption data suggest that an increased number of high energy (> 40 kJ/mol) sites are available for strong CO2 adsorption with increased lanthanum content. With this increase in strongly bound CO2, there is an increase in weakly bound CO2, which may compete with H2S for adsorption sites. The use of low weight loadings of La/γ-Al2O3 has yielded materials with sulfur capacities of 10-20 times more sulfur at breakthrough than the unsupported lanthanum oxide on a per gram of lanthanum basis. Regeneration of these materials in dilute air resulted in the rapid poisoning with sulfate, and the capacity decreased to that of the γ-Al2O3. Regeneration with humidified argon yielded a consistent capacity that was more than double that of the γ-Al2O3. While successful at removing H2S from H2, La/γ-Al2O3 was unsuccessful when CO, CO2 & H2O were added to the feed. The enhanced adsorption of CO2 found with DRIFTS and volumetric chemisorption acts to compete with H2S for adsorption sites, while H2O present resulted in an inhibition of the sulfidation. On the basis of characterization, an ideal sorbent would bind CO2 less strongly than alumina. From this, alumina is an unsuitable support for hot gas desulfurization with lanthana when significant quantities of CO2 or H2O are present.
The Physical Presence of Survivance in The Heirs of Columbus
Creators: name: Schaak, Hogan
Publisher: name: Transmotion
Year: 2020

description: Critics attempt to make sense of the fantastic happenings in Gerald Vizenor’s The Heirs of Columbus (1991) by taking his plethora of theoretical claims, the pinnacle of which is a concept called “survivance,” and applying them to the novel. However, no one has considered that Heirs does not simply give body to Vizenor’s theory, but surpasses it, crafting and testing a new definition of “survivance.” I argue in this paper that Vizenor’s Heirs adds a new dimension of “survivance,” portrayed particularly in his character Stone. In this way, “survivance” moves beyond its generally agreed upon definition as personal and intellectual liberation from identity constraints in order to encompass physical and communal healing as well.

Heartbreak House, 1959: A Fantasia in What Manner?

Subjects: Theater

description: This thesis is a reconstruction of the 1959 Broadway production of G. Bernard Shaw’s play Heartbreak House. The first chapter examines the world in 1959. The second chapter consists of biographies of those involved in the production. The third chapter describes the action of the play and analyzes the reasons for the directorial, design, and acting choices. The fourth and final chapter gives the critical response to the play. The paper questions whether or not the vision of the director was realized by the cast and crew, and understood by the audience. It finds that while some aspects were understood the larger political point was lost, perhaps due to conflicts backstage or to cuts made from the original Shavian script.

description: The knowledge about heterogeneity on agricultural fields is essential for a sustainable and effective field management. This study investigates the performance of Synthetic Aperture Radar (SAR) data of the Sentinel-1 satellites to detect variability between and within agricultural fields in two test sites in Germany. For this purpose, the temporal profiles of the SAR backscatter in VH and VV polarization as well as their ratio VH/VV of multiple wheat and barley fields are illustrated and interpreted considering differences between acquisition settings, years, crop types and fields. Within-field variability is examined by comparing the SAR backscatter with several crop parameters measured at multiple points in 2017 and 2018. Structural changes, particularly before and after heading, as well as moisture and crop cover differences are expressed in the backscatter development. Furthermore, the crop parameters wet and dry biomass, absolute and relative vegetation water content, leaf area index (LAI) and plant height are related to SAR backscatter parameters using linear and exponential as well as multiple regression. The regression performance is evaluated using the coefficient of determination (R 2 ) and the root mean square error (RMSE) and is strongly dependent on the phenological growth stage. Wheat shows R 2 values around 0.7 for VV backscatter and multiple regression and most crop parameters before heading. Single fields even reach R 2 values above 0.9 for VV backscatter and for multiple regression related to plant height with RMSE values around 10 cm. The formulation of clear rules remains challenging, as there are multiple influencing factors and uncertainties and a lack of conformity.
Targeting the tumour microenvironment : characterizing the anti-vascular effects of the hypoxic cytotoxin tirapazamine
Creators: name: Baker, Jennifer Hazel Elizabeth
Publisher: name: University of British Columbia
Year: 2010

description: Tirapazamine (TPZ) is a bioreductive prodrug with greater toxicity to hypoxic cells in vitro, and anti-vascular activity in tumours grown in vivo in mice. Considerable inter- and intra-tumour heterogeneity occurs in response to the anti-vascular effects of TPZ. The main hypothesis for the work described in this thesis is that features of the tumour microenvironment confer tumour sensitivity to TPZ-mediated vascular dysfunction. Tumours exhibiting less sensitivity to the anti-vascular effects of TPZ had evidence of greater pre-treatment vascular function, including greater blood flow or permeability measured using DCE-MRI derived biomarkers and tumour mapping data of high molecular weight fluorescent dyes injected intravenously. Modulation of nitric oxide (NO) levels decreased the density of perfused blood vessels and sensitized tumours to the anti-vascular effects of TPZ. Additional vascular phenotype features such as relatively poor vascular maturity were also found to correlate with greater tumour sensitivity to TPZ-mediated vascular dysfunction. Greater toxicity of TPZ to hypoxic cells in vitro led to the hypothesis that blood oxygenation may have an impact on tumour sensitivity to TPZ-mediated vascular dysfunction in vivo. Tumours from mice that had moderate bleeding-induced anemia or that were breathing lowered (7-10%) oxygen were sensitized to the anti-vascular effects of TPZ. In vitro assays showed that human microvascular tube structures are sensitive to damage by TPZ at clinically relevant concentrations and oxygen levels. TPZ may be reduced by cellular nitric oxide synthase (NOS), and NOS is competitively inhibited by TPZ to result in decreased amounts of NO. Enhanced anti-cancer effects have previously been observed for other vascular disrupting agents (VDAs) and hypoxic cytotoxins when combined with NOS inhibitors. These findings led to studies presented in this thesis, which show that TPZ-mediated vascular dysfunction is enhanced by co-administration with a NOS inhibitor, and this combined activity can lead to reduced cancer growth. Results from this thesis suggest that features of the tumour microenvironment, including tumour vascular phenotype, blood oxygenation and tumour hypoxia impact tumour sensitivity to TPZ-mediated vascular dysfunction. In addition, inhibiting NOS in combination with TPZ is a therapeutically advantageous strategy that merits further investigation.
Sordid Pasts, Indigenous Futures: Necropolitics and Survivance in Louis Owens' Bone Game
Creators: name: Delgado, Francisco
Publisher: name: Transmotion
Year: 2020

description: This article develops from current examinations of the link between racial subjectivity and death that increased in prominence after the publication of Achille Mbembe’s 2003 article “Necropolitics.” In a context specific to Native American/Indigenous Studies, Jodi Byrd (Chickasaw) points out how designating an individual or group “Indian” allows for their genocide. Elaborating on Mbembe’s and Byrd’s respective frameworks, my article provides a necropolitical reading of Louis Owens’ 1994 novel Bone Game, arguing that the book prompts readers to discuss and reconcile the historical relationships between death and subjectivity and, more importantly, explore the possibilities of Indigenous futures and sovereignty. This article draws on Indigenous scholarship like Leanne Betasamosake Simpson’s concept of ‘Indigenous freedom,’ Vine Deloria Jr.’s critique of Anthropological study, and Vizenor’s notion of ‘survivance,’ in its analysis of the struggles and survivance strategies of Owens’ characters, all of whom emphasize Native agency and sovereignty over the predominant, mainstream narrative of Native tragedy. The injustices and tragedies are part of the California landscape, written into the state and national histories, what Owens once described in an interview as “dark” but what this article characterizes as dystopic based on the novel’s “defamiliarization” of a well-known setting for political purposes (Booker) and based on how it “depends on and denies history” (Baccolini). While illustrating the link between history and the present day of the book, up to and including how we can construct the future, my reading posits that the actions of Cole and his family help readers imagine possibilities for Indigenous futures. The first part of my article’s title draws on one of Cole’s quips about the history of California. Cole’s reference to the state’s “sordid past” critiques the common conception of California as a terra nullius paradise. California long exists in the public imagination as a source of hope (for gold, for a new beginning); it is thus appropriate that Owens sets his novel here to explore his own sense of hope for an Indigenous future, one that accounts for settler colonialism while also beginning to move past it, one that does not skirt the hard work of reconciliation and sovereignty.

description: I describe ongoing work on development of Bayesian methods for exploring periodically varying phenomena in astronomy, addressing two classes of sources: pulsars, and extrasolar planets (exoplanets). For pulsars, the methods aim to detect and measure periodically varying signals in data consisting of photon arrival times, modeled as non-homogeneous Poisson point processes. For exoplanets, the methods address detection and estimation of planetary orbits using observations of the reflex motion "wobble" of a host star, including adaptive scheduling of observations to optimize inferences.

description: The work presented here evaluates the control of redox sensitive processes involved in phagosomal protein degradation which include the activities of cysteine cathepsins and gamma-interferon-inducible lysosomal thiol reductase (GILT). The catalytic mechanisms of these enzymes are dependent on reduced active site thiol (SH) groups making them susceptible to oxidative inactivation via reactive oxygen species (ROS). First, we evaluate how phagosomal thiol-dependent processes are influenced by the activation status of the macrophage. We show that interleukin-4 (IL-4) activation of murine bone marrow derived macrophages (BMMØs) results in a dramatic increase in phagosomal protein degradation. This was due to a decrease in oxidative inactivation of cysteine cathepsins and phagosomal disulfide reduction as a result of decreased NADPH oxidase (NOX2) -mediated ROS production. In addition, we found that IL-4 activation resulted in increased expression of cysteine cathepsins S and L which also enhanced phagosomal proteolysis in a NOX2-independent manner. Second, the influence of GILT on phagosomal thiol-dependent protease activity was evaluated in BMMØs to address how cysteine cathepsins are maintained in their reduced active state. We show that during NOX2 inhibition, GILT maintains phagosomal proteolysis in the early phagosome. The effect of GILT on proteolysis was enhanced in IL-4-activated BMMØs (with/without NOX2 inhibition). Furthermore, in a reconstituted system, we observed enhanced cathepsin S activity in the presence of recombinant active GILT. Last, we investigated the involvement of cytosolic redox control systems on phagosomal thiol-dependent processes. A novel phagosome-specific disulfide reduction assay was screened against a small molecule bioactives library. Results of the screen indicated the putative involvement of thioredoxin reductase (TrxR) in supporting phagosomal disulfide reduction. Furthermore, nicotinamide adenine dinucleotide phosphate (NADPH) depletion in BMMØs decreased both phagosomal disulfide reduction and proteolysis, implicating NADPH as a putative source of phagosomal reducing equivalents. Finally, through conditional depletion of the selenocysteine tRNA in BMMØs, we provide evidence for the involvement of selenoproteins, a family of redox enzymes which includes TrxR, in phagosomal disulfide reduction. Overall, the work presented in this dissertation contributes to our understanding of how macrophages regulate redox sensitive protein degradation in the phagosome.
Spiralic Time and Cultural Continuity for Indigenous Sovereignty: Idle No More and The Marrow Thieves
Creators: name: De Vos, Laura Maria
Publisher: name: Transmotion
Year: 2020

description: By virtue of the way the young people in Idle No More were experiencing time through round dancing, we can understand how they were able to counteract or respond to the underlying assumptions of a Canadian national temporality of reconciliation that is linear and progressive, and which thinks of historical redress through the process of reconciliation as in and of itself an end rather than a continuing spiral. Not only is Idle No More’s focus on the spiralic (cyclical, but transformed for the moment rather than mere repetition) resurgence of cultural traditions and ancestral knowledges exemplary of a new generation’s experience of spiralic time, this experience of time is also better able to intervene in the national temporality of reconciliation. I argue that Cherie Dimaline’s post-apocalyptic YA novel The Marrow Thieves (2017) does similar consciousness raising work on radical relationality and Indigenous youth’s power to build their futures in the now. Through the novel's organizing principle of spiralic time which puts Indigenous youth at the center, it reveals this temporal aspect central to the Idle No More movement which otherwise might go unnoticed. Similarly to round dancing, which is about bringing a future into reality in the present through a connection with the past, and which in this way pushes back against the temporality of a progress narrative that the Canadian nation is aiming to push onto Indigenous people, The Marrow Thieves offers a counter reality to that of Canadian settler “progress” and “reconciliation”. Writing directly to Indigenous youth to invite them to see themselves as part of a continuing spiral of Indigenous presence going back to when time began and continuing into a time when they themselves will be ancestors, the novel emphasizes Indigenous youth’s central role in resurgence, within and beyond Idle No More.

description: The time series of synthetic aperture radar (SAR) data are commonly and successfully used to monitor the biophysical parameters of agricultural fields. Because, until now, mainly backscatter coefficients have been analysed, this study examines the potentials of entropy, anisotropy, and alpha angle derived from a dual-polarimetric decomposition of Sentinel-1 data to monitor crop development. The temporal profiles of these parameters are analysed for wheat and barley in the vegetation periods 2017 and 2018 for 13 fields in two test sites in Northeast Germany. The relation between polarimetric parameters and biophysical parameters observed in the field is investigated using linear and exponential regression models that are evaluated using the coefficient of determination (R2) and the root mean square error (RMSE). The performance of single regression models is furthermore compared to those of multiple regression models, including backscatter coefficients in VV and VH polarisation as well as polarimetric decomposition parameters entropy and alpha. Characteristic temporal profiles of entropy, anisotropy, and alpha reflecting the main phenological changes in plants as well as the meteorological differences between the two years are observed for both crop types. The regression models perform best for data from the phenological growth stages tillering to booting. The highest R2 values of the single regression models are reached for the plant height of wheat related to entropy and anisotropy with R2 values of 0.64 and 0.61, respectively. The multiple regression models of VH, VV, entropy, and alpha outperform single regression models in most cases. R2 values of multiple regression models of plant height (0.76), wet biomass (0.7), dry biomass (0.7), and vegetation water content (0.69) improve those of single regression models slightly by up to 0.05. Additionally, the RMSE values of the multiple regression models are around 10% lower compared to those of single regression models. The results indicate the capability of dual-polarimetric decomposition parameters in serving as meaningful input parameters for multiple regression models to improve the prediction of biophysical parameters. Additionally, their temporal profiles indicate phenological development dependent on meteorological conditions. Knowledge about biophysical parameter development and phenology is important for farmers to monitor crop growth variability during the vegetation period to adapt and to optimize field management.

description: Previous studies of science reveal that research collaborations require negotiations as researchers form themselves into a project team that confronts a research question, collects data, and transforms the data into agreed-upon facts. Collaborations that span geographic, institutional, and epistemic borders are increasing in frequency. Funding agencies like Canada’s health research grant agency, CIHR, are encouraging collaborations that span multiple academic disciplines and include research users throughout the research process. This change from the traditional research model has the potential to affect the academic and health services landscapes through its emphasis on non-traditional research products and CIHR’s expectation that research users will allocate portions of their limited time budget to areas of knowledge production that may not be of interest to non-researchers. Erevna is the pseudonym for a five-year CIHR-funded multidisciplinary applied health services research project examining new knowledge uptake by health care aides in seniors’ long-term care facilities across Canada’s Prairie Provinces. Erevna’s project team included investigators from several universities and decision makers from provincial health authorities, and urban and rural elder care facilities. The team’s varied membership, specifically the inclusion of research users in the project’s formative stages, provided an opportunity to document a boundary-spanning research collaboration as it unfolded. Existing studies of science have focused on laboratory and natural scientists. Erevna, as an applied health services research project, took place firmly in the “real world” of Canada’s long-term care sector. This setting’s inherent heterogeneity brought with it complexities not found in controlled laboratory settings, or in studies that do not involve human beings interacting naturally. Through long-term ethnographic fieldwork spread over more than two years, I used actor-network theory to explore how people spanning institutional, organizational, provincial, and national boundaries formed into an actor-network that pursued a common goal and how Erevna’s actor-network persisted over five-years. I also documented the challenges to Erevna’s stability. In this dissertation, I compare Erevna’s public and behind-the-curtain narratives revealing the complexities of science-in-the-making that published accounts generally omit. I examine how membership in Erevna’s component social worlds and epistemic cultures influenced the collaboration. Finally, I explore the construction of Erevna’s actor-network, and examine effective and ineffective strategies for its maintenance.

description: Monitoring the phenological development of agricultural plants is of high importance for farmers to adapt their management strategies and estimate yields. The aim of this study is to analyze the sensitivity of remote sensing features to phenological development of winter wheat and winter barley and to test their transferability in two test sites in Northeast Germany and in two years. Local minima, local maxima and breakpoints of smoothed time series of synthetic aperture radar (SAR) data of the Sentinel-1 VH (vertical-horizontal) and VV (vertical-vertical) intensities and their ratio VH/VV; of the polarimetric features entropy, anisotropy and alpha derived from polarimetric decomposition; as well as of the vegetation index NDVI (Normalized Difference Vegetation Index) calculated using optical data of Sentinel-2 are compared with entry dates of phenological stages. The beginning of stem elongation produces a breakpoint in the time series of most parameters for wheat and barley. Furthermore, the beginning of heading could be detected by all parameters, whereas particularly a local minimum of VH and VV backscatter is observed less then 5 days before the entry date. The medium milk stage can not be detected reliably, whereas the hard dough stage of barley takes place approximately 6–8 days around a local maximum of VH backscatter in 2018. Harvest is detected for barley using the fourth breakpoint of most parameters. The study shows that backscatter and polarimetric parameters as well as the NDVI are sensitive to specific phenological developments. The transferability of the approach is demonstrated, whereas differences between test sites and years are mainly caused by meteorological differences.
Stress and well-being in breast cancer survivors : the influence of personality, socio-demographics, cancer-related characteristics, and physical activity levels
Creators: name: Hadd, Valerie
Publisher: name: University of British Columbia
Year: 2010

description: Cancer is now considered to be one of the most prevalent chronic diseases in Canada, with breast cancer emerging as the most common type of cancer diagnosed in Canadian women (Canadian-Cancer-Society, 2009). As breast cancer patients move to long-term survivorship, they face new challenges that extend beyond end of treatment (Deimling et al, 2003) which can have direct influences on quality of life (Ferrell et al., 1995). Previous research has often failed to use stress frameworks to examine stress relationships faced by breast cancer survivors (BCS) and has seldom investigated the effect of specific cancer-related stressors and their meaning on quality of life. To address these limitations, the current study investigated the influence of stress-related variables on quality of life of BCS post-treatment using Lazarus’ framework. Moreover, the direct and indirect effects of individual characteristics, including physical activity and personality trait, as well as cancer-related characteristics on stress-related variables were investigated. The final sample included 365 women who had been diagnosed with breast cancer, had completed treatment, and were between the age of 29 and 90 years (Mage = 61.58, SD = 11.36). Structural equation modeling techniques were used to test a hypothesized model based on Lazarus’ framework. The measurement and structural models testing the most global hypothesized model showed good model fit (RMSEA < .08, CFI > .90, TLI > .90), whereby direct and indirect effects of stressors, physical activity, and optimism on quality of life were shown. Together, these constructs explained 61% and 70% of the variance in physical and mental health respectively, highlighting the direct effect of stressors on quality of life above and beyond the role of cognitive appraisal. Experiencing more stressors was significantly associated with reporting lower levels of quality of life. Furthermore, personality had a direct effect on mental health whereas being physically active was positively associated with physical health. Overall, findings provided partial support for Lazarus’ model and highlighted some of the potential benefits of physical activity for cancer survivors. These results could be used to guide the design of interventions aimed at increasing physical and mental health in breast cancer survivors.

description: With this third paper of a series we present Johnson-Gunn B,g,V,r,i,z multicolour photometry for 79 objects, including a significant fraction of the faintest galaxies around NGC5044, assessing group membership on the basis of apparent morphology and low-resolution optical spectroscopy to estimate redshift for 21 objects. Together, dE's and Im's provide the bulk of the galaxy luminosity function, around M(g)\sim-18.0, while the S0 and dSph components dominate, respectively, the bright and faint-end tails of the distribution. This special mix places the NGC 5044 group just "midway" between the high-density cosmic aggregation scale typical of galaxy clusters, and the low-density environment of looser galaxy clumps like our Local Group. The bright mass of the 136 member galaxies with available photometry and morphological classification, amounts to a total of 2.3x10^{12}M_sun while current SFR within the group turns to be about or higher than 23M_sun/yr. In this regard, a drift toward bluer integrated colours is found to be an issue for dE's pointing to a moderate but pervasive star-formation activity even among nominally "quiescent" stellar systems. Through Lick narrow-band index analysis, dwarf ellipticals are found to share a sub-solar metallicity (-1.0 < [Fe/H]

description: Turbulent convection models are thought to be good tools to deal with the convective overshooting in the stellar interior. However, they are too complex to be applied in calculations of stellar structure and evolution. In order to understand the physical processes of the convective overshooting and to simplify the application of turbulent convection models, a semi-analytic solution is necessary. We obtain the approximate solution and asymptotic solution of the turbulent convection model in the overshooting region, and find some important properties of the convective overshooting: I. The overshooting region can be partitioned into three parts: a thin region just outside the convective boundary with high efficiency of turbulent heat transfer, a power law dissipation region of turbulent kinetic energy in the middle, and a thermal dissipation area with rapidly decreasing turbulent kinetic energy. The decaying indices of the turbulent correlations $k$, $\bar{u_{r}'T'}$, and $\bar{T'T'}$ are only determined by the parameters of the TCM, and there is an equilibrium value of the anisotropic degree $ω$. II. The overshooting length of the turbulent heat flux $\bar{u_{r}'T'}$ is about $1H_k$($H_k=|\frac{dr}{dlnk}|$). III. The value of the turbulent kinetic energy at the convective boundary $k_C$ can be estimated by a method called \textsl{the maximum of diffusion}. Turbulent correlations in the overshooting region can be estimated by using $k_C$ and exponentially decreasing functions with the decaying indices.

description: In wireless systems there is always a trade-off between reducing the transmit power and mitigating the resultant signal-degradation imposed by the transmit-power reduction with the aid of sophisticated receiver algorithms, when considering the total energy consumption. Quantum-assisted wireless communications exploits the extra computing power offered by quantum mechanics based architectures. This paper summarizes some recent results in quantum computing and the corresponding application areas in wireless communications.

Comparing the Fission-Fusion Dynamics of Spider Monkeys (Ateles geoffroyi) From Day to Night

subject: Fission-Fusion Dynamics

description: Environmental resource and risk both constrain grouping patterns, but may be weighted differently between day and night. Primates with high fission-fusion dynamics may change their grouping patterns and behavior in tandem with a shift from resource competition to risk avoidance. Using scan data (January 2013-August 2013), I compared subgroup size, stability, cohesion, behavior, and sleeping tree reuse patterns of black-handed spider monkeys (Ateles geoffroyi) at day and dusk at Runaway Creek Nature Reserve, Belize. At dusk, subgroup size significantly increased, and the monkeys rested and engaged in actively social behavior significantly more than during the day. Individuals clustered into family groups at dusk, increasing their distance from presumed non-relatives. Some sleeping trees were preferentially reused over others. Predation risk may make a larger, more cohesive subgroup optimal at night, but the limited quantity and fixed location of preferentially reused sleeping trees may keep subgroups from dramatically changing.
A class of interior solutions corresponding to a $(2+1)$ dimensional asymptotically anti-de Sitter spacetime

description: Lower dimensional gravity has the potential of providing non-trivial and valuable insight into some of the conceptual issues arising in four dimensional relativistic gravitational analysis. The asymptotically anti-de Sitter (2+1) dimensional spacetime described by Ba$\tilde{n}$ados, Teitelboim and Zanelli (BTZ) which admits a black hole solution, has become a source of fascination for theoretical physicists in recent years. By suitably choosing the form of the mass function $m(r)$, we derive a new class of solutions for the interior of an isotropic star corresponding to the exterior (2+1) asymptotically anti-de Sitter BTZ spacetime. The solution obtained satisfies all the regularity conditions and its simple analytical form helps us to study the physical parameters of the configuration in a simple manner.

description: The Province of Alberta has expressed an interest in conservation offsets as a new policy tool to promote land stewardship. The tool is enabled by provisions of the Alberta Land Stewardship Act. This thesis explores what Alberta must do in order to develop and implement an effective and credible conservation offset mechanism. It reviews the concept of conservation offsets and some of the key issues inherent to it. Focussing primarily on legal and regulatory aspects, it reviews the experience of conservation offset regimes for wetlands in the United States and for native vegetation in the State of Victoria, Australia. Drawing lessons from each of these case studies, it considers Alberta’s policy position and makes recommendations for bringing an Alberta conservation offset system to fruition.

description: (Abridged) We attempt to infer the accretion mechanism and radiative processes giving rise to the SEDs of a well-defined optically-selected sample of LINERs showing a definite detection of broad Halpha emission (LINER 1s). We construct SEDs for six LINER~1s with simultaneous UV and X-ray fluxes, and we looked for multiwavelength, radio to X-ray and UV to X-ray, correlations. At a given X-ray luminosity, the average SED of the six LINER 1s in our sample: (1) resembles the SED of radio-loud quasars in the radio band, ~-2.7, (2) exhibits a weak UV bump, ~-1.17+-0.02 with a dispersion sigma=0.01, and (3) displays a X-ray spectrum similar to radio-quiet quasars. The bolometric luminosities inferred from the SEDs are extremely faint, at least two orders of magnitude lower than AGN. The X-ray bolometric correction, kappa_(2-10 keV), of our sample is lower than in the case of AGN, with a mean value of 16. We find a strong anticorrelation between the radio loudness parameter, R_X, and the Eddington ratio for our sample, confirming previous results. Moreover, we find a positive correlation between the radio luminosity and the X-ray luminosity which places AGN-powered LINERs, on a radio-power scale, right between low luminosity Seyferts and low luminosity radio galaxies. We complement our alpha_ox list with values derived on a well defined sample of UV-variable LINERs, and establish a strong positive correlation between alpha_ox (considering negative values) and the Eddington ratio, in contrast to the correlation found for luminous AGN. Lastly, we tested two different fundamental planes existing in the literature on our sample, in an attempt to put constraints on the debated origin of the X-ray emission, "RIAF versus jet". The results came contradictory with one pointing toward a RIAF-dominated X-ray emission process and the other pointing toward a jet domination.

description: We describe the "islands of inversion" that occur when approaching the neutron drip line around the magic numbers N=20, N=28 and N=40 in the framework of the Interacting Shell Model in very large valence spaces. We explain these configuration inversions (and the associated shape transitions) as the result of the competition between the spherical mean field (monopole) which favors magicity and the correlations (multipole) which favor deformed intruder states. We also show that the N=20 and N=28 islands are in reallity a single one, which for the Magnesium isotopes is limited by N=18 and N=32.
