description: The body of work presented within this document is wide-ranging, sometimes performative, material based or ephemeral. Although I discuss my use of traditional media like painting, drawing and video, I also describe how I expanded the very notion of the ‘tool’ for making art by working with domestic objects. At the heart of my practice is the evolution of my children as ‘cooperators’ and finally, a re-making of myself into a ‘cyborg-artist-mother,’ an alter-ego who I call imother. My research explores the relationship between humans and technology through the lens of my concerns as a parent. This is within the context of the significant changes occurring in the ontology of social machine learning which is fuelled by the development of highly controversial, albeit effective algorithms that allow social media applications (and others developed to share media) to exploit our highly consumptive human behaviour. This thesis does not endorse a luddite politics. Instead, I describe how my practice evolved from painting into an inquiry about connectivity — a connectivity between my art practice and parenting and during the recent Covid-19 pandemic more widely, realizing the importance of creating a ‘cyborg-artist-parent’ community. Throughout my discussion, I draw attention to the problems I see emerging from my children’s dependence on digital technology, social media and apps for entertainment and play. My discussion therefore hones in on how I ‘queered’ the space of play through my art practice, first through the medium of painting, and then evolving into interventions in online gaming.

The Foraging Behaviour of Bumble Bees, Mediated by the Costs of Wing-Worn Flight

description: Bumble bees accumulate wing wear while foraging. If wing-worn workers face higher costs of flight, they should reduce their wing use, perhaps to increase their residual lifespan and net lifetime contribution to their colony. Measuring four behavioural variables (flight amount, flight frequency, choice of flower density, and distance travelled), I found that wing-worn workers sometimes used their wings less than pristine-winged bumble bees. Long-tongued, wing-worn workers were also more likely to forage on flowers with short corollas, which reduced their wing use. Wing use also depended on both past and present wing wear. Bees given experimental wing wear flew less, and bees with high natural wing wear used their wings less when feeding on Cirsium arvense. This study emphasizes the importance of wing wear in explaining the foraging behaviour of bumble bees. Wing-worn workers reduce their wing use in a manner predicted to offset higher flight costs of wing wear.

description: The 10-antenna prototype of the multifrequency Siberian radioheliograph is described. The prototype consists of four parts: antennas with broadband front-ends, analog back-ends, digital receivers and a correlator. The prototype antennas are mounted on the outermost stations of the Siberian Solar Radio Telescope (SSRT) array. A signal from each antenna is transmitted to a workroom by an analog fiber optical link, laid in an underground tunnel. After mixing, all signals are digitized and processed by digital receivers before the data are transmitted to the correlator. The digital receivers and the correlator are accessible by the LAN. The frequency range of the prototype is from 4 to 8 GHz. Currently the frequency switching observing mode is used. The prototype data include both circular polarizations at a number of frequencies given by a list. This prototype is the first stage of the multifrequency Siberian radioheliograph development. It is assumed that the radioheliograph will consist of 96 antennas and will occupy stations of the West-East-South subarray of the SSRT. The radioheliograph will be fully constructed in autumn of 2012. We plan to reach the brightness temperature sensitivity about 100 K for the snapshot image, a spatial resolution up to 13 arcseconds at 8 GHz and polarization measurement accuracy about a few percent. First results with the 10-antenna prototype are presented of observations of solar microwave bursts. The prototype abilities to estimate source size and locations at different frequencies are discussed.

description: Abstract
Three simple, new, accurate and precise methods were developed and validated on the basis of ICH guidelines for estimation of Evogliptin tartrate in pure and its tablet. Method 1: AUC by UV spectrophotometry technique utilizing 262 to 266nm for measurement of analyte in tablet. Method 2: 1st Order derivative spectrophotometry utilizing 258nm for estimation of analyte in the tablet. The linearity and range were found to be 10 to 270µg/ml for method 1 & 2. The sample and standard solutions were prepared in the methanol. % RSD was found to be less than 2 in tablet and recovery study of both Method 1 & 2. Method 3 comprises RP-HPLC method using Enable column C18 and mobile phase containing Methanol & water in the ratio of 70 and 30. The flow rate of 1 ml/min, with detection at 267nm, & temperature 250 C were used for analysis purposes. The retention time was found to be 2.806min. The linearity range was found to be 10-80µg/ml. The linear regression equation was found to be Y = 4006.6714 x + 713.6349 and Correlation coefficient (r2) = 0.9999. % RSD is less than 2 in the precision, recovery and robustness studies of the proposed method. So the method was precise, accurate and robust in nature. Method-3 is more accurate & precise in comparison to method 1 & 2.
An X-ray Source Model and Characterization Method for Computing kV Radiation Dose

description: According to the American Association of Physicists in Medicine Task Group (AAPM) 75, it is the responsibility of the medical physics community to assess, reduce, and optimize the imaging dose delivered during image-guided radiation therapy. It is currently difficult to accurately estimate patient-specific spatial dose distributions deposited by kilovoltage (kV) cone-beam CT (CBCT) using existing techniques. This thesis describes the development and validation of a characterization method and virtual point source model for describing kV radiographic and CBCT x-ray imaging units for our in-house kV dose computation software, kVDoseCalc. kV CBCT beams have spatial and spectral fluence variations. In this thesis, the spectrum is characterized using the accelerating potential (kVp) and half-value layer (HVL). These are matched to spectra generated by third-party freeware. The fluence is then isolated from measured in-air kerma. We assume that the fluence is a function of three separate independent variables: the transverse-axis spectra; and the transverse- and radial-axis fluence profiles. This work demonstrates that kV x-ray sources can be characterized using in-air ionization chamber measurements of HVL and kerma profiles. The characterization method and model are validated by comparing the absorbed dose computed by kVDoseCalc with measurements taken using ionization chambers and thermoluminescent detectors. Doses were measured in homogeneous and heterogeneous block phantoms for radiographic imaging procedures. We then measured imaging doses in homogeneous cylindrical and heterogeneous anthropomorphic phantoms for default CBCT protocols. The percent dose difference between measurement and computation was generally ≤3% in homogeneous and ≤6% in heterogeneous geometries, respectively. In the anthropomorphic phantom, the average percent difference ranged from 3–6% depending on the imaging protocol and site. The described method makes the accurate computation of radiographic and CBCT absorbed dose possible. This method has since been used by others in our group to accurately characterize a conventional CT scanner, superficial/orthovoltage therapy units, and to characterize an in-vivo film dosimetry program in our centre. Our technique is notable for relying only on empirical measurements. It allows a more accurate kV dose computation than treatment planning systems adapted for this purpose and is more clinically feasible than conventional Monte Carlo simulations.
A New Non-Abelian Topological Phase of Cold Fermi Gases in Anisotropic and Spin-Dependent Optical Lattices

description: To realize non-Abelian s-wave topological superfluid (TS) of cold Fermi gases, generally a Zeeman magnetic field larger than superfluid pairing gap is necessary. In this paper we find that using an anisotropic and spin-dependent optical lattice (ASDOL) to trap gases, a new non-Abelian TS phase appears, in contrast to an isotropic and spin-independent optical lattice. A characteristic of this new non-Abelian TS is that Zeeman magnetic field can be smaller than the superfluid pairing gap. By self-consistently solving pairing gap equation and considering the competition against normal state and phase separation, this new phase is also stable. Thus an ASDOL supplies a convenient route to realize TS. We also investigate edge states and the effects of a harmonic trap potential.
Utilization of machine learning for the detection of self-admitted vulnerabilities

description: Motivation: Technical debt is a metaphor that describes not-quite-right code introduced for short-term needs. Developers are aware of it and admit it in source code comments, which is called Self- Admitted Technical Debt (SATD). Therefore, SATD indicates weak code that developers are aware of. Problem statement: Inspecting source code is time-consuming; automatically inspecting source code for its vulnerabilities is a crucial aspect of developing software. It helps practitioners reduce the time-consuming process and focus on vulnerable aspects of the source code. Proposal: Accurately identify and better understand the semantics of self-admitted technical debt (SATD) by leveraging NLP and NL-PL approaches to detect vulnerabilities and the related SATD. Finally, a CI/CD pipeline will be proposed to make the vulnerability discovery process easily accessible to practitioners.

description: Dukagjinis in the Middle Ages. The Geographical Area and some Characteristics. In this article is tried will try to give a general overview of the history of Dukagjinis which consisted of some families seemingly belonging to the same tribe and were part of the Albanian nobles in the Middle Ages. Dukagjinis show up many times in documents, and they were an essential factor in the occurrences taking place in Albania in the Middle Ages, especially during Skanderbeg's period. Besides the expansion of their prevalence in North Albanian regions and their distribution into some European countries after the Ottoman occupation, they result to be present even among noble Albanian families with the highest duration until they died out in the 17th century. In this paper, besides the historical data about them in Albanian territories, the reader will also find information on their presence in Italy, Istria and the Ottoman Empire.

description: The BESS-Polar collaboration has recently performed a precise measurement of the local antiproton flux which is consistent with a pure secondary production of antiprotons. We constrain a possible primary component originating from dark matter pair-annihilations. We derive limits on the annihilation cross section which are stronger than or comparable to those from the PAMELA satellite experiment for dark matter masses up to 200 GeV. Especially, we exclude thermal WIMPs with masses in the range 3-20 GeV if they annihilate dominantly into quark pairs unless their cross section is velocity suppressed.

description: My impetus as an artist is to promote a sense of nature connectedness in the public consciousness, with the understanding that this leads to more pro-environmental attitudes. I gain insights from Indigenous ecological perspectives, the science of plant intelligence, environmental activist movements, and artists whose work facilitates reflection on biocentric values. My methodology includes on site fieldwork to investigate ways to express the language of trees. Dr. Suzanne Simard’s research on the underground network of roots and mycorrhizal fungi enabling communication between trees, and Indigenous philosophies of animism and interspecies connection all support my work. To address these concepts in my thesis project, I initiated a collaborative art installation, “Net-Work”, utilizing handcrafted yarn work — knitting, weaving, and crochet — as my medium, a significant shift for me in materiality and methodology. Although the use of marginalized “women’s craft” carries post-feminist stigma, third-wave feminists are embracing that challenge using craft activism, or “craftism”, as an alternative form of protest. Despite my initial concerns regarding initiating a craft-based socially engaged art project, the numerous and enthusiastic responses I received from participants worldwide is evidence of a resurgence in traditional hand crafts, while demonstrating how social activism can stimulate dialogue and raise awareness of issues, in this case facilitating a tangible response to the effects of human activity on non-human kin. Reliance on the internet for connection and dissemination of information to participants has introduced an unforeseen correlation between online social networking and the underground web of tree connection. While I have now received a sufficient number of fibre works to create the installation, this project continues to evolve, supported by future exhibition opportunities and widening public interest.

description: Operational pollution from offshore oil and gas exploration and production has become a major environmental problem for governments. Regulators have adopted either prescriptive or performance-based regulation to address this problem. This thesis examines both approaches and argues that performance-based regulation is best suited for the purpose of regulating operational pollution. The thesis further identifies essential elements of effective performance-based regulation and identifies the key elements in the Norwegian regime for regulating offshore operational pollution including: the use of performance-based regulation; comprehensive legislative arrangement; and a regulator with clearly defined roles and responsibilities. The thesis then explores the extent to which these elements identified are present in the Ghanaian regime to regulate operational pollution. The thesis concludes by recommending a transfer of the key elements from Norway to Ghana to ensure that an effective regime is in place for regulating operational pollution from the offshore oil and gas industry going forward.

description: The electronic and magnetic properties of a neutral substitutional nickel (Ni$_s^0$) impurity in diamond are studied using density functional theory in the generalized gradient approximation. The spin-one ground state consists of two electrons with parallel spins, one located on the nickel ion in the $3d^9$ configuration and the other distributed among the nearest-neighbor carbons. The exchange interaction between these spins is due to $p-d$ hybridization and is controllable with compressive hydrostatic or uniaxial strain, and for sufficient strain the antiparallel spin configuration becomes the ground state. Hence, the Ni impurity forms a controllable two-electron exchange-coupled system that should be a robust qubit for solid-state quantum information processing.

description: We present relativistic magnetohydrodynamic modelling of jets running into hydrostatic, spherically symmetric cluster atmospheres. For the first time in a numerical simulation, we present model cluster atmospheres based upon the Universal Pressure Profile (UPP), incorporating a temperature profile for a typical self-similar atmosphere described by only one parameter - $M_{500}$. We explore a comprehensive range of realistic atmospheres and jet powers and derive dynamic, energetic and polarimetric data which provide insight into what we should expect of future high-resolution studies of AGN outflows. From the simulated synchrotron emission maps which include Doppler beaming we find sidedness distributions that agree well with observations. We replicated a number of findings from our previous work, such as higher power jets inflating larger aspect-ratio lobes and the cluster environment impacting the distribution of energy between the lobe and shocked regions. Comparing UPP and $β$-profiles we find that the cluster model chosen results in a different morphology for the resultant lobes with the UPP more able to clear lobe material from the core; and that these different atmospheres influence the ratio between the various forms of energy in the fully developed lobes. This work also highlights the key role played by Kelvin-Helmholtz (KH) instabilities in the formation of realistic lobe aspect-ratios. Our simulations point to the need for additional lobe-widening mechanisms at high jet powers, for example jet precession. Given that the UPP is our most representative general cluster atmosphere, these numerical simulations represent the most realistic models yet for spherically symmetric atmospheres.

description: The quantum free particle on the sphere $S_κ^2$ ($κ>0$) and on the hyperbolic plane $H_κ^2$ ($κ<0$) is studied using a formalism that considers the curvature $\k$ as a parameter. The first part is mainly concerned with the analysis of some geometric formalisms appropriate for the description of the dynamics on the spaces ($S_κ^2$, $\IR^2$, $H_κ^2$) and with the the transition from the classical $κ$-dependent system to the quantum one using the quantization of the Noether momenta. The Schrödinger separability and the quantum superintegrability are also discussed. The second part is devoted to the resolution of the $κ$-dependent Schrödinger equation. First the characterization of the $κ$-dependent `curved' plane waves is analyzed and then the specific properties of the spherical case are studied with great detail. It is proved that if $κ>0$ then a discrete spectrum is obtained. The wavefunctions, that are related with a $κ$-dependent family of orthogonal polynomials, are explicitly obtained.
Making ‘opposite-sex’ love : discourse and discord in Linglong Women's Pictorial Magazine, 1931-1937
Creators: name: Wang, Gary
Publisher: name: University of British Columbia
Year: 2010

description: This thesis is a case study of Linglong Magazine, published in Shanghai from 1931 to 1937. It examines representational conflict in the construction of normative heterosexuality and marriage – a regulatory measure that contained the prospect of female autonomy during a period of flux. The study is a preliminary exercise in Michel Hockx’s formulation of “horizontal reading,” which regards journal issues as collectively authored texts and emphasizes the spatial relation of printed material. Referring to both texts and images in the magazine, I find that heteronormativity is covertly challenged at the same time that same-sex love and the rejection of marriage are stigmatized. Moreover, alternative voices and sensibilities that encompass homoeroticism are hinted at, which I seek to recover. I thus underscore how normative gender constructs are negotiated and challenged in Linglong at the same time that they are reaffirmed. In reading Linglong horizontally, I show how romanticized heterosexual love is matched by vociferous attacks on men and idealization of female bonds, which are at times valued over relations with men. In my view, what Barbara Mittler identifies in the magazine as cheeky misandrism – a “distaste for men” or “man-hating” – was a playful marketing device that also provided a channel for contributors (many of whom were readers) to covertly express what was becoming increasingly taboo to articulate overtly – namely, support for female autonomy and alternatives to compulsive heterosexuality and marriage. Drawing on Gao Yunxiang’s analysis of Linglong’s promotion of athleticism in the name of national strengthening, I suggest that the new fashion of robust beauty, in conjunction with references to Euro-American art forms that sanction depictions of the human form, legitimized the display of female bodies and expanded notions of femininity in erotically charged ways that include dimensions of homoeroticism. Pleasure and fear are thus engendered simultaneously on the pages of Linglong.

The return to $1 spent on herbicides and Insecticides was $1.05 and $1.03, respectively. Corn farmers generally applied herbicides and insecticides at optimal levels in 1980. Yields did not vary among tillage systems, but were significantly lower for farmers who mechanically cultivated their fields more than once after planting compared to farmers who cultivated less. Pesticide use and cost varied significantly among these cultural practices.
Toluene Degradation in a Compost Biofilter: Modeling and Experimental Evaluation

description: Biofiltration is an effective approach for the remediation of carbon-based air pollutants in which the degradation is achieved through the bioactivity of certain microorganisms present in the bioreactor. The growth of the microorganisms within the biofilter not only depends on the carbon source, but also on the other nutrients. Nitrogen, for example, is considered to be essential for microbial growth and survival. Most biofilter models do not consider nitrogen limitation, and also assume a constant microbial concentration within the biofilter, which is not always true. Hence, a growth model was developed in this study which can describe the relationship between microbial growth and nitrogen utilization within a toluene biofilter. From the simulation results, it was estimated that at 1 g m-3 inlet toluene concentration and an empty bed residence time of 72 s, 87.6% removal efficiency was achieved on day 100 without any additional nitrogen supplement when the initial nitrogen content was 1% (w/w). A model describing toluene mass transfer by diffusion in the biofilm was also developed. The simulation results suggest that the effect of diffusion limitation on toluene biodegradation is significant in a thick biofilm (i.e., 100 μm) as opposed to a thin biofilm (i.e., 1 μm). An experimental evaluation of toluene biofiltration was carried out using compost. Preliminary experiments led to a low and unstable activity. It was hypothesized that isolation of the toluene degrading strain and inoculation on sterile compost will lead to higher and more stable activity. Bench-scale experiments were conducted to isolate and characterize toluene degrading microorganisms from compost. DNA analysis and sequencing data suggested that the strain was Nocardia sp. The Nocardia strain was inoculated on a sterile biofilter. The biofilter was operated for 50 days with 0.4, 1.1 and 1.4 g m-3 inlet concentrations resulting in 96.1%, 82% and 69.8% average removal efficiencies respectively, confirming the hypothesis. This is the first report that shows Nocardia sp. as the sole toluene degrader in a compost biofilter. The experimental data were compared with the growth model and the results suggest that the growth model can successfully predict the degradation efficiency of the compost biofilter.
Sex-specific effects of prenatal ethanol exposure on hippocampal synaptic plasticity in adolescent rats
Creators: name: Titterness, Andrea Kay
Publisher: name: University of British Columbia
Year: 2010

description: The hippocampus is a brain region intimately involved with learning and memory. Long-term depression (LTD) and long-term potentiation (LTP) are putative mechanisms behind learning and memory. Prenatal and postnatal events that alter LTP and/or LTD also impair hippocampal-dependent learning and memory. Prenatal stress and prenatal ethanol exposure (PNEE) can both independently reduce LTP in male offspring; acute postnatal stress enhances LTD in males. It remains to be determined how these events alter synaptic plasticity in adolescent females. Stress-induced changes to LTD might be more pronounced following PNEE due to a heightened stress response in ethanol-exposed offspring. In Chapter 2, it was found that acute stress was required for the expression of LTD in control males but blocked LTD in females. Acute stress was required for LTD in males following PNEE but LTD was not apparent in females. The experiments in Chapter 3 were designed to investigate how combined exposure to stress and ethanol in utero affect LTP in the hippocampus of adolescent males and females. PNEE reduced LTP in males but enhanced LTP in females. In animals not exposed prenatally to ethanol, prenatal stress significantly reduced LTP in males but not females. On the other hand, LTP was reduced in males exposed both ethanol and stress in utero but the magnitude of LTP was not significantly different from that of ethanol-exposed males. In females, however, prenatal stress reduced the ethanol-induced enhancement of LTP. These findings indicate that synaptic plasticity in adolescent males and females is differentially affected by prenatal and postnatal events. Putative mechanisms behind the observed plasticity will be discussed in Chapter 4. Specifically, PNEE can delay the onset of puberty, which might alter the influence of the depressant effect of estradiol on synaptic plasticity in adolescent females. PNEE has previously been shown to “masculinize” the female brain and “feminize” the male brain, which might influence synaptic plasticity during adolescence. The expression of the placental barrier to CORT is also altered by prenatal stress and PNEE and might also contribute to observed changes in synaptic plasticity. Potential pitfalls of the experiments and future directions will be presented.

description: This deliverable builds upon work undertaken from D4.1. Critical review of EPE initiatives as well as other research projects to develop and trial a framework for developing an Education and Public Engagement programme for carbon capture and storage in the context of the Cork case study area. A methodological approach is detailed for the creation of EPE programmes informed by just transition literature, illustrating a variety of EPE activities that are typically employed as part of consultative, collaborative and co-creative public engagement processes. Examples of good EPE practice of Irish organisations are explored. Informed by this review a framework for EPE was developed for the Cork case study area – including the creation and curation of content meeting the needs of the target audience. Key elements of this framework were trialled in local communities to evaluate its effectiveness, identify areas of potential improvement and ascertain its transferability. Finally, to aid in the measurement of such a programme's success, key performance indicators (KPIs) are presented for each of the three dimensions of justice – distributive, procedural, and recognition justice.

description: Cyclin-dependent kinase 5 (Cdk5) was previously shown to mediate sensitivity of multiple myeloma cells to the proteasome inhibitor bortezomib. The mechanism by which this occurs was investigated. The idea that Cdk5 could promote the expression of the target of bortezomib PSMB5 via the transcription factor Nrf2 was first examined. However, contrary to published results, I did not find that PSMB5 expression is reduced following Cdk5 knockdown, and Nrf2 activity was also unchanged. Next, a synthetic lethal DNA repair defect from combined Cdk5 knockdown and bortezomib was explored. Both treatments produce an impaired DNA damage response. I show that Cdk5 can affect BRCA1 localization, Further investigation is required to fully characterize the role of Cdk5 in the DNA damage response. Bioinformatics supports the importance of Cdk5 in myeloma as we show that Patients with the highest expression of Cdk5 experience poorer survival following bortezomib treatment. Also, Cdk5 is upregulated in over 50% of all cancers.

description: Fed cattle production grew by one-third during 1964-80. Meanwhile, the number of farmer cattle feeder operations fell by about half to only 113,000 as commercial feedlot enterprises effectively used capital, labor, and marketing to seize over 70 percent of the market. The drop in number of individual farmers who feed cattle should continue in the eighties. Overall, feedlots operated by farmers are becoming fewer but larger as numbers decline east of the Mississippi River, and as cattle feeders establish more farms in the western Corn Belt and southern High Plains.

description: Since the discovery of the first exoplanets, those most adequate for life to begin and evolve have been sought. Due to observational bias, however, most of the discovered planets so far are gas giants, precluding their habitability. However, if these hot Jupiters are located in the habitable zones of their host stars, and if rocky moons orbit them, then these moons may be habitable. In this work, we present a model for planetary transit simulation considering the presence of moons and planetary rings around a planet. The moon's orbit is considered to be circular and coplanar with the planetary orbit. The other physical and orbital parameters of the star, planet, moon, and rings can be adjusted in each simulation. It is possible to simulate as many successive transits as desired. Since the presence of spots on the surface of the star may produce a signal similar to that of the presence of a moon, our model also allows for the inclusion of starspots. The result of the simulation is a light curve with a planetary transit. White noise may also be added to the light curves to produce curves similar to those obtained by the CoRoT and Kepler space telescopes. The goal is to determine the criteria for detectability of moons and/or ring systems using photometry. The results show that it is possible to detect moons with radii as little as 1.3 R$_{\oplus}$ with CoRoT and 0.3 R_{\oplus}$ with Kepler.

description: Over the past 20 years, numerous therapies have emerged which are changing the face of how we understand and treat advanced cancer. These drugs, new therapeutic approaches, and improved outcomes have enabled more patients to live longer with advanced cancer than ever before. However, the control achieved through these interventions is neither permanent nor consistent, and maintaining disease control in the advaced setting, requires ongoing treatments. More and more often, the term chronic cancer is being used to characterize advanced (stage III or IV) disease that is no longer curable, but is, or may become stable in response to treatment (Berlinger & Lederman Flamm, 2009). In addition to changing the language used to speak about incurable but treatable cancer, these new medical interventions are changing how individuals and their families experience this new phase of their cancer journey. In an effort to understand the needs of this emerging population, this qualitative study, informed by Gadamerian philosophical hermeneutics, was designed and conducted with the primary goal of understanding how living with chronic cancer is experienced by families. Unstructured interviews were conducted, recorded, transcribed verbatim, and analyzed with that goal in mind. The findings of this research highlight that living with chronic cancer is substantially different than living with either curative cancer or dying of cancer. Individuals and families who are living with incurable but treatable cancer inhabit the space between these two extremes, which is metaphorically referred to in this dissertation as the liminal world of chronic cancer. Participants spoke eloquently of their struggle to learn to live well in limbo. The metaphor of a heroic journey has been utilized to organize and reflect both on the complexity and similarities of the experiences that these families grappled with. This dissertation concludes by identifying how these research findings apply to oncology nursing practice and what innovations in education, professional development supports, and practice roles would contribute to improved support for families who are living with chronic cancer.
Bifurcation Boundary Conditions for Switching DC-DC Converters Under Constant On-Time Control

description: Sampled-data analysis and harmonic balance analysis are applied to analyze switching DC-DC converters under constant on-time control. Design-oriented boundary conditions for the period-doubling bifurcation and the saddle-node bifurcation are derived. The required ramp slope to avoid the bifurcations and the assigned pole locations associated with the ramp are also derived. The derived boundary conditions are more general and accurate than those recently obtained. Those recently obtained boundary conditions become special cases under the general modeling approach presented in this paper. Different analyses give different perspectives on the system dynamics and complement each other. Under the sampled-data analysis, the boundary conditions are expressed in terms of signal slopes and the ramp slope. Under the harmonic balance analysis, the boundary conditions are expressed in terms of signal harmonics. The derived boundary conditions are useful for a designer to design a converter to avoid the occurrence of the period-doubling bifurcation and the saddle-node bifurcation.

description: This thesis presents an examination of the publications about the human remains from Tombs I, II, and III at Vergina. An overview of the controversy surrounding this topic presents a starting point, an explains why the bones have become so contentious. Since most arguments about identity propose Philip II or his son Arrhidaios, I have examined the historical context of both their murders and burials, and those of their wives Kleopatra and Adea-Eurydike. I asses whether it is possible to identify the occupants of these tombs from osteological evidence alone, as most current scholarship asserts. Special emphasis has been given to the skeletal remains from Tomb II, to determine if either Philip II or Arrhidaios can be confirmed as the occupant of the main chamber. Anatomical analysis of Philip II's known battle injuries finds that proof of identity cannot be reached through examination of the remains alone.

description: We examine the chemical properties of 5 cosmological hydrodynamical simulations of an M33-like disc galaxy which have been shown to be consistent with the morphological characteristics and bulk scaling relations expected of late-type spirals. These simulations are part of the Making Galaxies In a Cosmological Context (MaGICC) Project, in which stellar feedback is tuned to match the stellar mass -- halo mass relationship. Each realisation employed identical initial conditions and assembly histories, but differed from one another in their underlying baryonic physics prescriptions, including (a) the efficiency with which each supernova energy couples to the ISM, (b) the impact of feedback associated with massive star radiation pressure, (c) the role of the minimum shut-off time for radiative cooling of Type II SNe remnants, (d) the treatment of metal diffusion, and (e) varying the IMF. Our analysis focusses on the resulting stellar metallicity distribution functions (MDFs) in each simulated (analogous) `solar neighbourhood' and central `bulge' region. We compare the simulated MDFs' skewness, kurtosis, and dispersion (inter-quartile, inter-decile, inter-centile, and inter-tenth-percentile regions) with that of the empirical solar neighbourhood MDF and Local Group dwarfs. We find that the MDFs of the simulated discs are more negatively skewed, with higher kurtosis, than those observed locally. We can trace this difference to the simulations' tight and correlated age-metallicity relations (compared with that of the Milky Way), suggesting that these relations within `dwarf' discs might be steeper than in L* discs and/or the degree of stellar orbital re-distribution and migration inferred locally has not been captured in their entirety, at the resolution of our simulations. The important role of metal diffusion in ameliorating the over-production of extremely metal-poor stars is highlighted.
