Aquatic ecosystem metabolism as a control of carbon transport in a managed forest
Creators: name: Ngo, Trisa
Publisher: name: University of British Columbia
Year: 2024

description: As the majority of Canada obtains its drinking water from forested watersheds, forest management to better address the effects of land use changes related to industries such as logging and urban development are of high public interest. To understand impacts on aquatic ecosystems from land use change it is essential to understand how carbon is cycled, transported, and stored throughout the ecosystem. Aquatic ecosystem metabolism (AEM), a key component of carbon cycling, can be evaluated by determining gross primary productivity (GPP) and ecosystem respiration (ER) within the water column of streams, rivers, lakes, and wetlands. AEM controls energy and material flow through aquatic ecosystems therefore linking environmental change and food webs to provide a useful framework for examining ecosystem function and productivity. The objective of this research was to investigate the role of AEM as a control on carbon transport, turnover, and fate in forested ecosystems under varying land use and streamflow conditions. The study was conducted in the University of British Columbia (UBC) Malcolm Knapp Research Forest (MKRF) located approximately 50 km east of Vancouver, BC containing forested and harvested blocks along a single 3.4 km stream reach containing four monitoring stations during late summer to winter 2022. This study examined the seasonal and spatial differences of AEM inputs and found that temporal and spatial disparities can have a significant effect on AEM and gas exchange rates at finer spatial scales. Overall, the stream reach demonstrated R exceeding GPP therefore indicating a negative net ecosystem production (NEP) and a heterotrophic stream reach. This study provides an exploratory investigation into AEM in a headwater stream of the Pacific Northwest.

We give sufficient conditions onto a topological semigroup $\mathscr{I}_λ^1$ to be non-$H$-closed. Also we describe the structure of countably compact Brandt $λ^0$-extensions of topological monoids and study the category of countably compact Brandt $λ^0$-extensions of topological monoids with zero.

Fixing for change : information practice and stories of aspiration in community-based repair initiatives
Creators: name: Kaczmarek, Michelle Ania
Publisher: name: University of British Columbia
Year: 2024

description: For over a decade, sharing platforms such as YouTube have offered do-it-yourself repair guidance 24/7 to households across North America. Yet, in-person repair events, where people physically meet up to repair together, were growing in numbers and popularity before the COVID-19 pandemic. Whether called Fixit Clinics or Repair Cafés, people gathered to repair artefacts (e.g., digital electronics, household appliances, clothing), assisted by volunteers with skills, tools, and expertise in different kinds of repair. In January 2020, I embarked on a dissertation project to explore why people in Metro Vancouver were dedicating their time and energy to help others repair items in person, including things that could be easily replaced via online shopping. My carefully planned research activities were soon upended by ever-shifting pandemic protocols, including lockdowns that also prevented repair cafés from operating. All of this led to a period of profound uncertainty for local repair organisations and required me to reimagine my research project. However, through my interviews with 13 repair café volunteers and organisers in Metro Vancouver, the disruption of the pandemic became an opening point to learn about what motivated participants to dedicate their time to repairing others’ broken objects and to consider the work of repair more broadly. Weaving together practice theory, narrative methods, and humanistic approaches, my dissertation explores questions with and of information practice, aspiration, and story to consider the possibilities, connections, and limitations of these concepts for understanding the potentialities of “repair”. By creating space to position participants’ lived experiences in conversation with scholars’ theorizing, my project reveals ways that involvement in repair activities offers more than opportunities to fix broken material objects. The work articulates and honours the diversity and different motivations of people coming together to work on repair, and illustrates the wide-ranging forms of labour, knowledge, and skills that go into making repair events “work”. I present implications for repair practitioners and advocates, librarians and information professionals, and policy makers to engage in locally relevant ways with systemic conditions that also need “fixing”, including civic engagement, growth-based economics, community resilience, and climate crisis.

description: This doctoral thesis is focused on the �lite of Turin during the late Middle Ages, with particular regard to parental structures and their reproductive strategies. In fact, the deep changes occurred in the �lite between 12th and 14th century are not only the result of the political decisions of the Dukes of Savoy and of the demographic crisis, but also the outcome of economic and social choices of the families. The research aims at showing how behaviours and events within parental groups have an effect on the political and social changes of the citizenship, taking into account residential patterns, economic strategies, inheritance models and financial investments. On the one hand, different combinations of these elements, in which inheritance patterns play an essential role, are crucial for the duration and success of parental groups; on the other hand, they have a significant impact on the political balances of the families and the �lite.

description: To temporally localize a signal in a signal stream in noisy environments, it is necessary to identify a suitable transformation that suppresses the noise-floor and amplifies the signal sections. In this computational test, different combinations of the discrete-time signal x and its transformation result y are convolved with a moving non-causal Dirichlet window. The transformation used here is a sinusoidal matched-filter.The test aims to determine which combination of input data leads to the highest amplitude ratio between the noise floor and the signal section.

description: It is generally believed that coupling the graviton (a classical Fierz-Pauli massless spin-2 field) to its own energy-momentum tensor successfully recreates the dynamics of the Einstein field equations order by order; however the validity of this idea has recently been brought into doubt [1]. Motivated by this, we present a graviton action for which energy-momentum self-coupling is indeed consistent with the Einstein field equations. The Hilbert energy-momentum tensor for this graviton is calculated explicitly and shown to supply the correct second-order term in the field equations; in contrast, the Fierz-Pauli action fails to supply the correct term. A formalism for perturbative expansions of metric-based gravitational theories is then developed, and these techniques employed to demonstrate that our graviton action is a starting point for a straightforward energy-momentum self-coupling procedure that, order by order, generates the Einstein-Hilbert action (up to a classically irrelevant surface term). The perturbative formalism is extended to include matter and a cosmological constant, and interactions between perturbations of a free matter field and the gravitational field are studied in a vacuum background. Finally, the effect of a non-vacuum background is examined, and the graviton is found to develop a non-vanishing ``mass-term'' in the action.

MASS SPECTROMETRY BASED PROFILING OF TWO DIFFERENT BIOLOGICAL SYSTEMS FOR POSSIBLE CLINICAL APPLICATION.
Creators: name: CUEVAS POLO, NEREA
Publisher: name: Universit� degli Studi di Milano
Year: 2014

description: Several techniques including two-dimensional electrophoresis, imaging, mass spectrometry, and bioinformatics are used in proteomics to identify, quantify, and characterize proteins for clinical applications. The main aim is to identify proteins involved in pathological processes and to understand how illness can lead to altered protein expression in order to develop new diagnostic and prognostic tests, to identify new therapeutic targets, and eventually to allow the design of individualized patient treatment. For this purpose this dissertation is divided into two main chapters. Chapter one concerns the development of a novel method to isolate exosomes. Normal human urine contains large numbers of exosomes, which are 40 to 100 nm vesicles that originate in multivesicular bodies from every renal epithelial cell type facing the urinary space. Exosomes are rich in potential biomarkers, especially membrane proteins such as transporters and receptors that may be up- or downregulated during disease states. Differential centrifugation methods are commonly used to purify exosomes from urine. Here, we developed a new method to isolate exosomes by solubilizing exosomes in 1 % Sarkosyl, an anphyphilic detergent, followed by a carbon fractionation. We used LC-MS/MS to profile the proteome of human urinary exosomes. Overall, the analysis unambiguously identified 1618 proteins, showing an enrichment of 61.3% in exosomal proteins, after performing a Gene Ontology analysis. Thus, our modified exosome precipitation method is a simple, fast, highly scalable, and effective alternative for the isolation of exosomes. It may facilitate either the identification of exosomal biomarkers from urine or the production of drug delivery devices. Chapter two concerns the identification of proteins in adhesive material of the capsalid Neobenedenia girellae by a proteomic approach based on de novo sequencing and database search to overcome the lack of information concerning the genome of these parasites. Glandular secretions were obtained by a new method, set up in our laboratory, which allowed collecting a small amount of secretion without any contamination from other tissues either from the parasites as well as from the skin of the host. The proteomic analysis reveals that the adhesive is mainly composed of cytoskeletal proteins (actin, keratin and tubulin) but contains also ATP-synthase, 78 kDa glucose regulated protein and albumin. This work reports for the first time the characterization of a novel bioadhesive material used by capsalid parasites to adhere to fish. Such information broadens our knowledge of the molecular mechanisms involved in adhesiveness of parasites to hosts. Moreover, it offers new clues in understanding the mechanism of stickiness and adhesion of cytoskeleton components, often involved in both physiological and pathological processes, including neurodegenerative diseases.

description: A detailed elastic neutron scattering study of the structural and magnetic phase transitions in single-crystal SrFe$_2$As$_2$ reveals that the orthorhombic (O)-tetragonal (T) and the antiferromagnetic transitions coincide at $T_\texttt{O}$ = $T_\texttt{N}$ = (201.5 $\pm$ 0.25) K. The observation of coexisting O-T phases over a finite temperature range at the transition and the sudden onset of the O distortion provide strong evidences that the structural transition is first order. The simultaneous appearance and disappearance within 0.5 K upon cooling and within 0.25 K upon warming, respectively, indicate that the magnetic and structural transitions are intimately coupled. We find that the hysteresis in the transition temperature extends over a 1-2 K range. Based on the observation of a remnant orthorhombic phase at temperatures higher than \emph{T}$_\texttt{O}$, we suggest that the T-O transition may be an order-disorder transition.

description: Seit der 2015 neu einsetzenden Flüchtlingswelle haben die Themen Islam, Djihadismus und Ausländerfeindlichkeit vermehrt Einzug in die Kinder- und Jugendliteratur gefunden. Autor_innen thematisieren sensibel, aber auch herausfordernd-provokant dieses Thema und beleuchten die unterschiedlichen Auswirkungen für die „westliche“ Welt.
Die nun vorliegende Diplomarbeit analysiert drei Jugendromane aus dem deutschsprachigen Raum: Anna Kuschnarowa „Djihad Paradise“, Antonia Michaelis „Die Attentäter“ sowie Peer Martin „Sommer unter schwarzen Flügeln“. Nach einer theoretischen Einbettung, die Kinder- und Jugendliteratur charakterisiert, eine Abgrenzung zwischen Kinder- und Jugendliteratur umreißt und den Islam sowie die Entwicklung des Djihads beleuchtet, werden im zweiten Teil die drei Texte anhand herausgearbeiteter Kategorien analysiert.
Die Figurencharakterisierung kombiniert mit Aspekten der Erzähltheorie – vorrangig den Ansätzen von Matías Martínez und Michael Scheffel – bilden das Fundament für die inhaltlich relevanten aufgegriffenen Themen. Religionen – konkret der Islam und das Christentum – werden dabei zum Teil miteinander in Beziehung gesetzt, religiös motivierte Motive aus-gedeutet und die Funktion innerhalb der Texte beleuchtet. Das familiäre Setting sowie die Liebesbeziehung zwischen den Figuren bilden die Grundlage für eine Charakterisierung der Figurenentwicklung sowie den Ausgangspunkt für eine etwaige Radikalisierung innerhalb der Neonazi- respektive Djihadistenszene in Deutschland. Diese Milieus werden vor allem durch Gewaltakte dominiert, was eine weitere Untersuchungskategorie darstellt. Dabei wird auch ein Blick auf die Differenzierung unterschiedlicher Gewaltformen geworfen, wobei vor allem die Tendenzen der strukturellen Gewalt (Johann Galtung) und viralen Gewalt (Jean Baudril-lards) aufgeschlüsselt werden. Ein (Selbstmord-)Anschlag von Seiten der Djihadisten sowie Neonazis bildet den Höhepunkt und zugleich das Ende der untersuchten Texte, wodurch das enorme Gewaltaufkommen erneut zum Ausdruck gebracht wird.

title: Risk-based integrity management (RBIM) of oil & gas offshore fixed steel structure platform
Creators: name: Elmasry, Ahmed
Publisher: name: Memorial University of Newfoundland
Year: 2020

description: Oil and gas offshore facilities structures operating in harsh environments are associated with high risk and the likelihood of failures. Hence, frequent inspections are needed to enhance the integrity and reliability of these 'platforms' structures using a rigorous strategy. The purpose of this research is to develop an integrity management strategy for an above and underwater offshore platform steel structure using risk-based integrity management assessment. This strategy is developed in four steps: step one identifies the elements of the platform structures suitable for risk-based integrity management; in step two, identifies anomalies and degradation mechanisms. The third step is hazard identification using qualitative risk analysis, by hazard and operability model, and quantitative risk analysis, by the fault tree model, to calculate the probability of failure then qualitative assessment assigns the consequences. Step four ranks the risk to prioritize inspection and maintenance schedule and build an integrity management strategy. As an outcome of this thesis, we are able to identify and categorize the degradation and deterioration mechanisms for the fixed steel structure platforms and gain an understanding of platform structural risks and rank these according to severity. Consequently, increase and enhance the reliability and integrity of the platform using an appropriate integrity management strategy. The proposed risk-based integrity management analysis proved that the risk-based inspection and risk-based maintenance methods used in this work are effective in terms of time, efficiency and cost, through reducing the frequency of inspection from 12 months to 24 or 36 months in some cases.

description: We estimate locations of the regions of the percolation and of the non-percolation in the plane $(λ,β)$: the Poisson rate -- the inverse temperature, for interacted particle systems in finite dimension Euclidean spaces. Our results about the percolation and about the non-percolation are obtained under different assumptions. The intersection of two groups of the assumptions reduces the results to two dimension Euclidean space, $\R^2$, and to a potential function of the interactions having a hard core. The technics for the percolation proof is based on a contour method which is applied to a discretization of the Euclidean space. The technics for the non-percolation proof is based on the coupling of the Gibbs field with a branching process.

description: We demonstrate the consistency at the next-to-leading-logarithmic (NLL) level of a factorization theorem based on Soft-Collinear Effective Theory (SCET) for jet shapes in e+e- collisions. We consider measuring jet observables in exclusive multijet final states defined with cone and k_T-type jet algorithms. Consistency of the factorization theorem requires that the renormalization group evolution of hard, jet, and soft functions is such that the physical cross-section is independent of the factorization scale mu. The anomalous dimensions of the various factorized pieces, however, depend on the color representation of jets, choice of jet observable, the number of jets whose shapes are measured, and the jet algorithm, making it highly nontrivial to satisfy the consistency condition. We demonstrate the intricate cancellations between anomalous dimensions that occur at the NLL level, so that, up to power corrections that we identify, our factorization of the jet shape distributions is consistent for any number of quark and gluon jets, for any number of jets whose shapes are measured or unmeasured, for any angular size R of the jets, and for any of the algorithms we consider. Corrections to these results are suppressed by the SCET expansion parameter lambda (the ratio of soft to collinear or collinear to hard scales) and in the jet separation measure 1/t^2 = tan^2(R/2)/tan^2(psi/2), where psi is the angular separation between jets. Our results can be used to calculate a wide variety of jet observables in multijet final states to NLL accuracy.

description: We study the generation of non-Gaussianity in models of hybrid inflation with two inflaton fields, (2-brid inflation). We analyse the region in the parameter and the initial condition space where a large non-Gaussianity may be generated during slow-roll inflation which is generally characterised by a large f_NL, tau_NL and a small g_NL. For certain parameter values we can satisfy tau_NL>>f_NL^2. The bispectrum is of the local type but may have a significant scale dependence. We show that the loop corrections to the power spectrum and bispectrum are suppressed during inflation, if one assume that the fields follow a classical background trajectory. We also include the effect of the waterfall field, which can lead to a significant change in the observables after the waterfall field is destabilised, depending on the couplings between the waterfall and inflaton fields.

The presence of both discontinuous and continuous glass transitions as well as the complex interplay between single-particle and collective dynamics are well captured by a recent extension of mode-coupling theory for fluids in porous media. The degree of universality of the mode-coupling theory predictions for related models of colloids is studied by introducing size-disparity between fluid and matrix particles, as well as softness in the interactions.

Symmetries of this type, which assign charges to H_u and H_d that forbid a tree level μterm, play an important role in scenarios for neutrino physics and gauge mediation that have been proposed in local F-theory model building. As demonstrated in arXiv:0906.4672, the presence of such a symmetry implies the existence of non-GUT exotics in the spectrum, when hypercharge flux is used to break the GUT group and to give rise to doublet-triplet splitting. These exotics are of precisely the right type to solve the unification problem in such F-theory models and might also comprise a non-standard messenger sector for gauge mediation. We present a detailed description of models with U(1)_PQ in the semi-local regime, which does not depend on details of any specific Calabi-Yau four-fold, and then specialize to the geometry of arXiv:0904.3932 to construct three-generation examples with the minimal allowed number of non-GUT exotics. Among these, we find a handful of models in which the D3-tadpole constraint can be satisfied without requiring the introduction of anti-D3-branes. Finally, because SU(5) singlets that carry U(1)_PQ charge may serve as candidate right-handed neutrinos or can be used to lift the exotics, we study their origin in compact models and motivate a conjecture for how to count their zero modes in a semi-local setting.

Populist memory politics and partisan immigration agendas in contemporary Germany
Creators: name: Schaefer, Hanne
Publisher: name: University of British Columbia

description: While both research on rising European anti-immigration parties and memory politics have vastly expanded in the last decades, the connection between the two has been widely neglected. To bridge this gap, this thesis studies the relationship between historic narratives and society's advocated boundaries by populist right-wing parties (PRPs). Utilizing the concepts of memory politics and Schinkel's conceptualization of imagined societies, this thesis analyzes the 2021 party manifesto of the right-wing populist Alternative for Germany (AfD). The analysis is structured by the following three questions: 1) Is German society portrayed as a historical one? 2) What historic moments are chosen as crucial for defining such a historic society? 3) How does the party's historic society narrative relate to its immigration agenda? Through a both inductive and deductive critical discourse analysis of the 2021 party manifesto, it argues that the AfD's anti-immigration position builds on the party's professed duty to protect German historic society by protecting the country's cultural and geographical boundaries. In the second part, this thesis explores the usefulness of the framework when applied to parties beyond the far-right political spectrum. Given the scope of the thesis, it chooses the left-wing populist party DIE LINKE. The findings indicate that the left-wing party shows a different challenge than the right: Namely, an ideological approach to German historical identity and immigration, lacking a true acknowledgement of immigrant history in Germany.

description: We study the spectral decomposition of the Laplacian on a family of fractals $\mathcal{VS}_n$ that includes the Vicsek set for $n=2$, extending earlier research on the Sierpinski Gasket. We implement an algorithm [24] for spectral decimation of eigenfunctions of the Laplacian, and explicitly compute these eigenfunctions and some of their properties. We give an algorithm for computing inner products of eigenfunctions. We explicitly compute solutions to the heat equation and wave equation for Neumann boundary conditions. We study gaps in the ratios of eigenvalues and eigenvalue clusters. We give an explicit formula for the Green's function on $\mathcal{VS}_n$. Finally, we explain how the spectrum of the Laplacian on $\mathcal{VS}_n$ converges as $n \to \infty$ to the spectrum of the Laplacian on two crossed lines (the limit of the sets $\mathcal{VS}_n$.)

Effects of honey bees (Apis mellifera L.) on the structure of plant-pollinator networks
Creators: name: Roulston, Terrell Trever

Year: 2024

description: Global biodiversity is under threat from a variety of factors, including habitat loss, land use change, climate change, and invasive species. Pollinators are crucial for biodiversity maintenance and global food security and are experiencing declines. One pollinator, the Western honey bee (Apis mellifera L.; Hymenoptera: Apoidea) is nearly ubiquitous in human altered landscapes. Despite honey bees being geographically widespread, knowledge of their impacts on plant-pollinator communities is incomplete. My study represents the first macroanalysis of honey bee competition in plant-pollinator networks from around the globe. Using an open-access database, I summarized bipartite network statistics for 123 plant-pollinator networks to test whether the proportion of interactions with honey bees in a network is associated with changes in network topology. Specifically, I calculated the normalized degree of interactions with honeybees (NDHB), defined as the total number of interacts divided by the richness of plant species. I predicted higher NDHB would be associated with (1) increased connectance (the realized proportion of possible interactions), (2) decreased modularity (degree of compartmentalization of subcommunities), and (3) increased nestedness (the amount of redundancy of interactions between specialist and generalist) of networks. I quantified these associations for entire networks containing all pollinators, as well as for Hymenopteran sub-networks. I also investigated whether honey bee normalized degree was associated with increased plant generalization (i.e., the mean number of links per species), and decreased pollinator generalization within Hymenopteran sub-networks. Overall, I found that honey bees were widespread, present in 77% (95/123) of networks worldwide. Results revealed that higher honey bee normalized degree was associated with decreased modularity, as well as increased plant generalization and increased pollinator generalization. Contrary to expectations, honey bee introduction was not associated with changes to network connectance or nestedness. While the results are correlational, they suggest that this widely introduced species is capable of modifying the structure of plant-pollinator networks leading to the homogenization of interactions, which could impact the persistence and coexistence of native plants and pollinators.

description: We combine SAURON integral field data of a representative sample of local early-type, red sequence galaxies with Spitzer/IRAC imaging in order to investigate the presence of trace star formation in these systems. With the Spitzer data, we identify galaxies hosting low-level star formation, as traced by PAH emission, with measured star formation rates that compare well to those estimated from other tracers. This star formation proceeds according to established scaling relations with molecular gas content, in surface density regimes characteristic of disk galaxies and circumnuclear starbursts. We find that star formation in early-type galaxies happens exclusively in fast-rotating systems and occurs in two distinct modes. In the first, star formation is a diffuse process, corresponding to widespread young stellar populations and high molecular gas content. The equal presence of co- and counter-rotating components in these systems strongly implies an external origin for the star-forming gas, and we argue that these star formation events may be the final stages of (mostly minor) mergers that build up the bulges of red sequence lenticulars. In the second mode of star formation, the process is concentrated into well-defined disk or ring morphologies, outside of which the host galaxies exhibit uniformly evolved stellar populations. This implies that these star formation events represent rejuvenations within previously quiescent stellar systems. Evidence for earlier star formation events similar to these in all fast rotating early-type galaxies suggests that this mode of star formation may be common to all such galaxies, with a duty cycle of roughly 1/10, and likely contributes to the embedded, co-rotating inner stellar disks ubiquitous in this population.

description: Cancer incidence and outcomes vary across populations and geographies over time. Understanding the extent and causes of disparities is essential to cancer control. This thesis developed statistical models to predict cancer incident cases and outcomes at the small-area level. Studies described geographic and temporal patterns, examined factors explaining the variation, and performed projections in geographic areas.
My thesis provides novel clinical contributions and methodological framework in terms of identifying factors that explain cancer disparities and quantify the existing and future burden of cancer at the small-area level, essential for cancer prevention and control. These models can be implemented in other cancers and diseases.

description: We present new radio and X-ray observations of Abell 262. The X-ray residual image provides the first evidence of an X-ray tunnel in this system while the radio data reveal that the central radio source is more than three times larger than previously known. We find that the well-known cluster-center S-shaped radio source B2 0149+35 is surrounded by extended emission to the east and south-west. The south-western extension is co-spatial with the X-ray tunnel seen in our new Chandra images while the eastern extension shows three clumps of emission with the innermost coincident with a faint X-ray cavity. The outer two eastern radio extensions are coincident with a newly detected X-ray depression. We use the projected separation of the emission regions to estimate a lower limit of tau_rep=28 Myr to the outburst repetition timescale of the central AGN. The total energy input into the cluster over multiple outburst episodes is estimated to be 2.2x 10^{58} ergs, more than an order of magnitude larger than previously thought. The total AGN energy output determined from our new observations shows that the source should be capable of offsetting radiative cooling over several outburst episodes.
