Thirsting for access? Public access to water for personal use in urban centres: A case study of Victoria, British ColumbiaGelb, Karen 08 December 2007 (has links)
The World Health Organization and the United Nations state that people normally access water through their place of residence. However, in North America people regularly need access to water services, such as toilets, fountains, or bathing facilities, when not in a private residence. The purpose of this thesis is to explore the current situation of access to water for personal uses for people outside a place of residence as an emergent research topic. To accomplish this, I conducted a literature review and a thematic analysis of nine key-informant interviews with stakeholders in Victoria. Findings from the research reveal that access to water for personal uses is limited in Victoria when outside a place of residence. Furthermore, the consequences and implications of this limitation directly and indirectly influence both individuals and the broader community. Finally, policy recommendations, action responses, and future research directions inform possible responses to address this issue.

Chimeric Virus Like Particles as Nanocarriers for Antibody Delivery in Mammalian Cells & Role of Groundnut Bud Necrosis Virus NSs in Viral Life CycleAbraham, Ambily January 2015 (has links) (PDF)
Knowledge of the dissociation constants of the ionizable protons of weak acids in aqueous media is of fundamental importance in many areas of chemistry and biochemistry. The pKa value, or equilibrium dissociation constant, of a molecule determines the relative concentration of its protonated and deprotonated forms at a specified pH and is therefore an important descriptor of its chemical reactivity. Considerable efforts have been devoted to the determination of pKa values by different experimental techniques. Although in most cases the determination of pKa values from experimental is straightforward, there are situations where interpretation is difficult and the results ambiguous. It is, therefore, not surprising that the capability to provide accurate estimates of the pKa value has been a central goal in theoretical chemistry and there has been a large effort in developing methodologies for predicting pKa values for a variety of chemical systems by differing quantum chemical techniques. A prediction accuracy within 0.5 pKa units of experiment is the desirable level of accuracy. This is a non-trivial exercise, for an error of 1 kcal/mol in estimates of the free energy value would result in an error of 0.74 pKa units.
In this thesis ab initio Car-Parrinello molecular dynamics (CPMD) has been used for investigating the Brϕnsted acid-base chemistry of weak acids in aqueous solution. A key issue in any dissociation event is how the solvating water molecules arrange themselves spatially and dynamically around the neutral and dissociated acid molecule. Ab initio methods have the advantage that all solvent water molecules can, in principle, be con- sidered explicitly. One of the factors that has inhibited the widespread use of ab initio MD methods to study the dissociation reaction is that dissociation of weak acids are rare events that require extremely long simulation times before one is observed. The metady- namics formalism provides a solution to this conundrum by preventing the system from revisiting regions of configuration space where it has been in the past. The formalism allows the system to escape the free-energy minima by biasing the dynamics with a history dependent potential (or force) that acts on select degrees of freedom, referred to as collective variables. The bias potentials, modeled by repulsive inverted Gaussians that are dropped during propagation, drive the system out of any free-energy minima and allow it to explore the configurational space by a relatively quick and efficient sampling. The the- sis deals with a detailed investigation of the Brϕnsted acid-base chemistry of weak acids in aqueous solutions by the CPMD-metadynamics procedure. In Chapter 1, current approaches for the theoretical estimation of pKa values are summarized while in Chapter 2 the simulation methodology and the metadynamics sampling techniques used in this
study are described.
The potential of the CPMD-metadynamics procedure to provide estimates of the acid dissociation constant (pKa) is explored in Chapter 3, using acetic acid as a test sys- tem. Using the bond-distance dependent coordination number of protons bound to the dissociating carboxylic groups as the collective variable, the free-energy profile for the dissociation reaction of acetic acid in water was computed. Convergence of the free-energy profiles and barriers for the simulations parameters is demonstrated. The free-energy profiles exhibit two distinct minima corresponding to the dissociated and neutral states of the acid and the deterrence in their values provides the estimate for pKa. The estimated value of pKa for acetic acid from the simulations, 4.80, is in good agreement with the experiment at value of 4.76. It is shown that the good agreement with experiment is a consequence of the cancellation of errors, as the pKa values are computed as the divergence in the free energy values at the minima corresponding to the neutral and dissociated state. The chapter further explores the critical factors required for obtaining accurate estimates of the pKa values by the CPMD-metadynamics procedure. It is shown that having water molecules sufficient to complete three hydration shells as well as maintaining water density in the simulation cell as close to unity is important.
In Chapter 4, the CPMD-metadynamics procedure described in Chapter-3 has been used to investigate the dissociation of a series of weak organic acids in aqueous solutions. The acids studied were chosen to highlight some of the major factors that influence the dissociation constant. These include the influence of the inductive effect, the stabilization of the dissociated anion by H-bonding as well as the presence of multiple ionizable groups. The acids investigated were aliphatic carboxylic acids, chlorine-substituted carboxylic acids, cis- and trans-butenedioic, the isomers of hydroxybenzoic acid and ophthalmic acids and its isomers. It was found that in each of these examples the CPMD-metadynamics procedure correctly estimates the pKa values, indicating that the formulism is capable of capturing these influences and equally importantly indicating that the cancellation of errors is indeed universal. Further, it is shown that the procedure can provide accurate estimates of the successive pKa values of polypro tic acids as well as the subtle difference in their values for different isomers of the acid molecule.
Changes in protonation-deprotonation of amino acid residues in proteins play a key role in many biological processes and pathways. It is shown that CPMD simulations in conjunction with metadynamics calculations of the free energy profile of the protonation- deprotonation reaction can provide estimates of the multiple pKa values of the 20 canonical α-amino acids in aqueous solutions in good agreement with experiment (Chapter 5). The distance-dependent coordination number of the protons bound to the hydroxyl oxygen of the carboxylic and the amine groups is used as the collective variable to explore the free energy profiles of the Brϕnsted acid-base chemistry of amino acids in aqueous solutions. Water molecules, sufficient to complete three hydration shells surrounding the acid molecule were included explicitly in the computation procedure. The method works equally well for amino acids with neutral, acidic and basic side chains and provides estimates of the multiple pKa values with a mean relative error with respect to experimental results, of 0.2 pKa units.
The tripeptide Glutathione (GSH) is one of the most abundant peptides and the major repository for non-protein sulfur in both animal and plant cells. It plays a critical role in intracellular oxidative stress management by the reversible formation of glutathione disulfide with the thioldisulfide pair acting as a redox buffer. The state of charge of the ionizable groups of GSH can influences the redox couple and hence the pKa value of the cysteine residue of GSH is critical to its functioning. In Chapter 6, it has been reported that ab initio Car-Parrinello Molecular Dynamics simulations of glutathione solvated by 200 water molecules, all of which are considered in the simulation. It is shown that the free-energy landscape for the protonation - deprotonation reaction of the cysteine residue of GSH computed using metadynamics sampling provides accurate estimates of the pKa and correctly predicts the shift in the dissociation constant values as compared to the isolated cysteine amino acid.
The dissociation constants of weak acids are commonly determined from pH-titration
curves. For simple acids the determination of the pKa from the titration curves using the Henderson-Hasselbalch equation is relatively straightforward. There are situations, however, especially in polyprotic acids with closely spaced dissociation constants, where titration curves do not exhibit clear inflexion and equivalence stages and consequently the estimation of multiple pKa values from a single titration curve is no longer straightfor-
ward resulting in uncertainties in the determined pKa values. In Chapter 7, the multiple dissociation constant of the hexapeptide glutathione disulfide (GSSG) with six ionizable groups and six associated dissociation constants has been investigated. The six pKa values of GSSG were estimated using the CPMD-metadynamics procedure from the free-energy profiles for each dissociation reaction computed using the appropriate collective variable. The six pKa values of GSSG were estimated and the theoretical pH-titration curve was then compared with the experimentally measured pH-titration curve and found to be in excellent agreement. The object of the exercise was to establish whether interpretation of pH-titration curves of complex molecules with multiple ionizable groups could be facilitated using results of ab initio molecular dynamics simulations.

The SWELSWÁLET of the W̱SÁNEĆ Nation: narratives of a “nation (re)building process”Fritz, Justin 07 December 2017 (has links)
In this Master’s thesis, I document my experience working with members of the W̱SÁNEĆ Nation in their efforts to revitalize the reef net fishery. As part of this research project, I interviewed W̱SÁNEĆ community members, and I created a digital map of reef net fishing locations (SWELSWÁLET). In each of these interviews, different W̱SÁNEĆ community members chose to frame reef net fishing differently, and they highlighted specific and unique “alternative political approaches” toward W̱SÁNEĆ cultural resurgence (Kew & Miller 1999:58-59). Despite these differences, each W̱SÁNEĆ community member that I interviewed believed that reef net fishing is something that “needs to be shared” (XA’LATE, pers. comm., June 14, 2016). In Chapter 1, I explore the variations in what specific W̱SÁNEĆ community members want shared. In Chapters 2 and 3, however, I examine the delicate cultural, political, and legal contexts that have made sharing a complicated process. In Chapter 2, I analyze how the BC Treaty Process (BCTP) has exacerbated conflicts among First Nations in British Columbia. Further, I discuss the impact that these conflicts have had on how the W̱SÁNEĆ Nation shares information with their intranational and international neighbours. In Chapter 3, I explore how my misaligned expectations of knowledge sharing in collaborative community-based research—as a white settler man—clashed with “the values and beliefs, practices and customs of [the W̱SÁNEĆ Nation]” (L. Smith 2012:15-16; Lassiter 2005). I also make recommendations for how settler researchers in the future should proceed with research projects in these contexts. / Graduate / 2019-12-06

Die Rezeption jüdisch-apokalyptischer Traditionen in christlichen Schriften, untersucht anhand des Verhältnisses von 5. und 6. Esra zu 4. EsraMilbach-Schirr, Lillia 03 December 2021 (has links)
Die Untersuchung betrachtet das Verhältnis der Schriften 4., 5. und 6. Esra zueinander.
Während die Apokalypse 4. Esra als Referenztext für neutestamentliche Schriften Gegenstand
zahlreicher Untersuchungen ist, wurden 5. und 6. Esra bisher lediglich als christliche
Hinzufügungen abgetan und nicht in einer bedeutungsvollen Beziehung zu 4. Esra verstanden.
Auf Grund der syrischen Tradition, die 4. Esra als geschlossene Schrift überliefert, wird
oftmals übersehen, dass in den lateinischen Traditionen 4. Esra ausschließlich im
Zusammenhang zu 5. und 6. Esra bezeugt ist.
Die Arbeit greift methodische Ansätze aus der alttestamentlichen und Apokryphenforschung
auf, um das Verhältnis der drei Schriften zueinander zu beschreiben. Handelt es sich um eine
willkürliche Zusammenordnung der Schriften oder lassen sich Ordnungsprinzipen und
durchgängige Konzepte erkennen, die eine Lesart als zusammenhängende und aufeinander
bezogene Gesamtschrift 2. Esdras nahe legen?
Die Arbeit geht dabei auf verschiedenen Ebenen vor: Zunächst werden die mittelalterlichen
Manuskripte, die die früheste vollständige Bezeugung der Schriften darstellen, analysiert und
ausgewertet. Wesentlich ist hierbei, dass die Schriften zwar immer im Zusammenhang
zueinander überliefert wurden, jedoch in sehr unterschiedlichen Anordnungen in den
jeweiligen Manuskripten enthalten sind. Auf synchroner Ebene werden zentrale Konzepte der
einzelnen Schriften exegetisch herausgearbeitet und zueinander in Bezug gesetzt. Schließlich
werden narratologisch und daramaturgisch die Erzählbögen der Einzelschriften analysiert und
ausgewertet, ob und wie ein Gesamthandlungsbogen von 2. Esdras erkennbar ist.
Gerade an der literarischen Figur des Esra zeigt sich, wie die unterschiedlichen Anordnungen
jeweils andere Aspekte der Figur in den Vordergrund rücken. Die literarische Gestalt des Esra
selbst wird zur Projektionsfläche für die Intentionen der späteren Tradentenkreise. Daher stellt
die jeweilige Anordnung der Schriften einen bewussten und sinnhaften Ausdruck der
theologischen Konzeptionen der Tradentenkreise dar. / The study is focused on the relation of 4th, 5th and 6th Ezra. While the Apocalypse 4th Ezra
as a reference text for New Testament writings is the subject of numerous studies, 5th and 6th
Ezra are normally dismissed as Christian additions and are not understood in a meaningful
relationship to 4th Ezra. Due to the fact that the Syriac tradition testifies 4th Ezra as an
independent writing, it is often ignored, that the Latin tradition exclusively features 4th Ezra
in the context of 5th and 6th Ezra. The study employs methodological approaches from the
361
Old Testament and Apocryphal research to investigate the relation between the three writings.
Should it be regarded as a random compilation of writings or are there indications for a
structural order or underlying concepts and motifs, which suggest an interrelated reading as a
composed writing of 2nd Esdras?
The study engages the subject with different approaches of research: first of all the medieval
manuscripts representing the oldest complete sources for the writing of 2nd Esdras are
evaluated. It is to be considered, that while all three writings are featured, the order of
arrangement of the writings varies in the different traditions. In a synchronic exegetical
analysis of the texts main themes and concepts are retraced and put in perspective to each
other. Finally in a narratologic and dramatic point of view the plots and the arc of suspense of
each writing is examined and considered in perspective of an underlying plot and
understanding of 2nd Esdras as one story line.
Especially in regard to the literary character of Ezra the different arrangements of the text
emphasize different theological aspects of the character. The figure of Ezra itself becomes a
projection space for the intentions of the later recipients. Therefore each arrangement of the
writings can be regarded as a deliberate and meaningful expression of the theological concept
of the recipients.

Glockenbecherzeitliche Gräber in Nordwestsachsen: Vom Becher(-n) zur TasseConrad, Matthias 29 May 2019 (has links)
Folgender Artikel stellt die nach der politischen Wende in Sachsen gefundenen und
bisher nur aus Vorberichten bekannten Glockenbechergräber vor. Die archäologisch-kulturelle Zuordnung der Gräber steht im Vordergrund, da einige Gräber keine oder kulturunspezifische Beigaben enthielten. Durch die Analyse eines internen und externen Grabkontextes kann der Großteil der Gräber der archäologischen Kultur mit Glockenbecher zugeordnet und die mit den Gräbern in Beziehung stehenden Befunde interpretiert werden. Weiterhin wird die Beziehungen zwischen den archäologischen Kulturen Glockenbecher und Aunjetitz thematisiert und auf besondere Aspekte der Glockenbecherbestattungssitte in Nordwestsachsen
eingegangen. / This article presents the Bell Beaker graves found in Northwest Saxony after 1989. Because some
of the burials contained none or only culturally non-specific grave goods, the overall analysis focused on the cultural classification of the graves. Investigation of the internal and external grave context allowed to classify the majority as graves of the Bell Beaker Culture and subsequently to interpret the features related to the graves. Furthermore the relationship between the Bell Beaker and Únetice Culture is discussed and special regional aspects of Bell Beaker burial customs are described in detail.

Energy saving opportunities in residential buildings: insights from technological and building energy code perspectivesLi, Bo 21 September 2020 (has links)
The residential building sector plays an important role in combating climate change in Canada. Many energy efficiency solutions along with new building energy standards have been implemented to improve building energy performance. However, their effects on energy saving and GHG emissions reduction vary due to the complexity of the building systems and the variability of their operational conditions. This work quantifies such variability in both energy efficiency devices and building energy standards implementation, respectively.
The first study in this dissertation assesses the energy savings from sensible heat recovery in a residential apartment suite in various locations across Canada. A series of detailed building energy performance models are developed in TRNSYS. The HVAC system’s annual energy consumption is simulated and the results are compared with and without HRV for each climate zone. The results show the heating energy savings of employing the HRV vary from 17 to 34% depending on the winter climatic conditions; while, the building cooling energy use can be increased due to the undesired thermal recovery occurring in the HRV during the cooling season.
The second study investigates the free cooling potential of outside air in various Canadian cities. A series of thermal models developed using BEopt 2.8 for a hypothetical single-family house with various window-to-wall ratios and building aspect ratios simulates hourly building cooling load profiles. The free cooling potential is analyzed by comparing the maximum available and the actual usable free cooling for various building features and different climates. The results indicate that, although free cooling is widely available in most areas of Canada during the summer and shoulder seasons, only 17-42% of such free cooling is usable without the use of thermal storage.
The last study examines the effects of two building energy standards - the BC Step Code and the Passive House criteria - on reductions in residential household space heating GHG emissions under different enforcement scenarios. The space heating energy and the GHG emissions are estimated using the forecast growth of single detached households for the period from 2020 to 2032. The results show that the space heating GHG emissions can be reduced by 77% and 89%, respectively if the BC Step Code or the Passive House criteria is implemented in Canada. It is also found the impacts of energy code on GHG emission mitigation are less significant in regions where the carbon intensity of the dominant heating fuels is low. / Graduate

After the daggers : politics and persuasion after the assassination of CaesarMahy, Trevor Bryan January 2010 (has links)
In this thesis, I examine the nature and role of persuasion in Roman politics in the period immediately following the assassination of Caesar on the Ides of March 44 B.C. until the capture of the city of Rome by his heir Octavianus in August 43 B.C. The purpose of my thesis is to assess the extent to which persuasion played a critical role in political interactions and in the decision-making processes of those involved during this crucial period in Roman history. I do this by means of a careful discussion and analysis of a variety of different types of political interactions, both public and private. As regards the means of persuasion, I concentrate on the role and use of oratory in these political interactions. Consequently, my thesis owes much in terms of approach to the work of Millar (1998) and, more recently, Morstein-Marx (2004) on placing oratory at the centre of our understanding of how politics functioned in practice in the late Roman republic. Their studies, however, focus on the potential extent and significance of mass participation in the late Roman republican political system, and on the contio as the key locus of political interaction. In my thesis, I contribute to improving our new way of understanding late Roman republican politics by taking a broader approach that incorporates other types of political interactions in which oratory played a significant role. I also examine oratory as but one of a variety of means of persuasion in Roman political interactions. Finally, in analyzing politics and persuasion in the period immediately after Caesar’s assassination, I am examining not only a crucial period in Roman history, but one which is perhaps the best documented from the ancient world. The relative richness of contemporary evidence for this period calls out for the sort of close reading of sources and detailed analysis that I provide in my thesis that enables a better understanding of how politics actually played out in the late Roman republic.

Credit risk measurement model for small and medium enterprises : the case of ZimbabweDambaza, Marx January 2020 (has links)
Abstracts in English, Zulu and Southern Sotho / The advent of Basel II Capital Accord has revolutionised credit risk measurement (CRM) to the extent that the once “perceived riskier bank assets” are now accommodated for lending. The Small and Medium Enterprise (SME) sector has been traditionally perceived as a riskier and unprofitable asset for lending activity by Commercial Banks, in particular. But empirical studies on the implementation of the Basel II internal-ratings-based (IRB) framework have demonstrated that SME credit risk is measurable. Banks are still finding it difficult to forecast SME loan default and to provide credit to the sector that meet Basel’s capital requirements. The thesis proposes to construct an empirical credit risk measurement (CRM) model, specifically for SMEs, to ameliorate the adverse effects of SME credit inaccessibility due to high information asymmetry between financial institutions (FI) and SMEs in Zimbabwe. A well-performing and accurate CRM helps FIs to control their risk exposure through selective granting of credit based on a thorough statistical analysis of historical customer data. This thesis develops a CRM model, built on a statistically random sample, known-good-bad (KGB) sample, which is a better representation of the through-the-door (TTD) population of SME loan applicants. The KGB sample incorporates both accepted and rejected applications, through reject inference (RI). A model-based bound and collapse (BC) reject inference methodology was empirically used to correct selectivity bias inherent in CRM domain. The results have shown great improvement in the classification power and aggregate supply of credit supply to the SME portfolio of the case-studied bank, as evidenced by substantial decrease of bad rates across models developed; from the preliminary model to final model designed for the case-studied bank. The final model was validated using both bad rate, confusion matrix metrics and Area under Receiver Operating Characteristic (AUROC) curve to assess the classification power of the model within-sample and out-of-sample. The AUROC for the final model (weak model) was found to be 0.9782 whilst bad rate was found to be 14.69%. There was 28.76% improvement in the bad rate in the final model in comparison with the current CRM model being used by the case-studied bank. / Isivumelwano seBasel II Capital Accord sesishintshe indlela yokulinganisa ubungozi bokunikezana ngesikweletu credit risk measurement (CRM) kwaze kwafika ezingeni lapho izimpahla ezazithathwa njengamagugu anobungozi “riskier bank assets” sezimukelwa njengesibambiso sokuboleka imali.

Yize kunjalo, amabhange asathola ukuthi kusenzima ukubona ngaphambili inkinga yokungabhadeleki kahle kwezikweletu kanye nokunikeza isikweletu imikhakha enemigomo edingekayo yezimali kaBasel.
