Introduction to electrochemistry
No full textAn excellent way into the subject'- New Scientist Introduction to Electrochemistry is the first major new text in the field in recent years. The author takes the student from the basics through to a level suitable for beginning a post-graduate course. The chapters cover theory from electrolytes through electrodes to cells, both equilibrium and dynamic. Applications and methods are given great emphasis, and the second part of the text focuses on these aspects with coverage of electrosynthesis, electroanalytical chemistry, industrial electrochemistry, batteries and corrosion. Scattered throughout the text are panels of historical and anecdotal information illustrating unusual and often amusing aspects of electrochemistry not normally presented to the student. This, plus the highly readable style adopted by Brynn Hibbert, and his use of fully worked problems at the end of each chapter, make Introduction to Electrochemistry the ideal undergraduate textbook choice. Introduction to Electrochemistry is part of the Macmillan Physical Sciences Series
The linguistic landscape of Post-Apartheid South Africa: politics and discourse
No full textLiesel Hibbert is Senior Lecturer in the Faculty of Education, Cape Peninsula University of Technology, South Africa. Her interests include discourse studies, South African writing, linguistic ethnography, political rhetoric, stylistics, the bilingual classroom and higher education pedagogy. Her previous publications include Multilingual Universities in South Africa (Multilingual Matters, 2014), which she co-edited with Christa van der Walt.The appointment of Nelson Mandela as President of South Africa in 1994 signalled the end of apartheid and transition to a new democratic constitution. This book studies discursive trends during the first twenty years of the new democracy, outlining the highlights and challenges of transforming policy, practice and discursive formations. The book analyses a range of discourses which signal how and by what processes the linguistic landscape and identities of South Africa’s inhabitants have changed in this time, finding that struggles in South African politics go hand in hand with shifts in the linguistic landscape. In a country now characterised by multilingualism, heteroglossia, polyphony and translanguaging, the author debates where the discourse practices of those born post-1994 may lead

K-shell Photoionization of Atomic Cl
No full textRecent measurements of the photoionization of atomic Cl in the vicinity of the 1s thresholds have motivated the present R-matrix calculation which takes into account relativistic effects via the Breit-Pauli operator. The computer code CIV3 of Hibbert and Glass and Hibbert, which also includes relativistic effects, is used to obtain the discrete wavefunctions. These are constructed with orbitals generated from a carefully-chosen large scale configuration interaction expansion. The open-shell nature of the Cl atom translates into the existence of actually four 1s thresholds, 3Po 0,1,2 and 1P 1. The results are analyzed with particular focus on the resonances leading up to the four thresholds, and the various effects that dominate the cross sections in this energy range are unraveled
Drones and American Smart Power: International Hierarchy and the Policing of Risk
No full textThis thesis analyzes the impacts of drones in state-level relations between the Obama administration and Middle Eastern states. Using a Foucauldian approach to security, which asserts that ‘the state’ exists as a set of practices that defines the border and the population of ‘the nation’, drones are examined through the Obama administration’s ‘Smart Power’ approach to foreign policy. In the discourses of many high-ranking officials within the administration, drones exist as a way for the American government to balance the withdrawal of military operations in the region while appearing to reduce the influence and impact of terrorist organizations. Because the United States discourses appear to be the authoritative, and therefore exclusively legitimate, voice on drones, the victims and persons who live under surveillance become excluded from important conversations about their continued use
The Halton "Deformation": Till: An Application of G.I.S. Basin Analysis Accompanied by a Sedimentological Examination of the Halton Basal Contact
No full textTitle: The Halton "Deformation": Till: An Application of G.I.S. Basin Analysis Accompanied by a Sedimentological Examination of the Halton Basal Contact, Author: Jarold W. Hibbert, Location: ThodeThe combined use of powerful computers and Geographic
Information System (G. I. S.) technology has only recently been
utilized as a geological tool in the study of unconsolidated
sediments. G. I. S. is applied in mapping the bedrock topography and
the geometry of the Halton Till in the Toronto region identifying
the technology as an essential component of any basin-wide
investigation. The bedrock surface exhibits a strong control over the
distribution of the Late Wisconsin aged Halton Till. The wide,
deep Laurentian channel contains thick sequences of Mid Wisconsin
sediments and is capped by a thin veneer of Halton Till. The
highland areas on the flanks of the Laurentian channel contain many
small bedrock channels oriented in a NW/SE trend parallel to ice
flow in the Late Wisconsin. These smaller bedrock channels are
often the sites of thick deposits of Halton Till. A sedimentological investigation of the Halton Till basal contact in outcrop reveals strong evidence of
underlying sediments into the Halton Till.
Sediment rafts, deformed basal zones in the Halton Till and sheared underlying
sediments suggest that the traditional classification of the Halton
Till as a lodgement complex is incorrect. A grainsize investigation of the lower 10 meters of the Halton Till supports the outcrop evidence of the incorporation of
underlying sediments into the lower Halton Till. The lithology of
the underlying unconsolidated sediments have a strong control on
the grainsize distribution of the lower 4 meters of the Halton Till. The geometry of the Halton Till, its sedimentology, grainsize distribution and glacitectonic deformation of underlying units all provide evidence for the deposition of the Halton Till as a
'deformation till'. Present investigations of the Halton Till as
a potential unit for the location of waste disposal sites should
take into consideration the geometry and sedimentology of the till. G.I.S. is a rapidly expanding field and it will play an important role in the study of Quaternary sediments (particularly aquifers) and the location of future hazardous waste disposal sites

Resistance, Infiltration, and Rapprochement: French Inhabitants in Spanish Upper Louisiana, 1766-1780
No full textThis thesis addresses the question of how the people of Upper Louisiana lived under Spanish imperial authority from 1766 to 1780, and how they reacted to the transition from French to Spanish governance. More specifically, this thesis looks at the direct interactions that inhabitants had with the Spanish colonial officials in St. Louis and New Orleans. To further understand these imperial relationships, it looks at how the French inhabitants from different colonies (Upper Louisiana, Lower Louisiana, and the Illinois Country) interacted with each other, as a way of understanding Spanish authority and its limits. This thesis is interested in the French inhabitants’ relationship with the Spanish state. It provides insight into the nature of governance and imperial relationships and examines how colonial peoples accepted and contested imperial regime change. This analysis helps to understand the limits of imperial authority on the imperial frontier. The three chapters are arranged chronologically and comparatively to understand the different responses of the French inhabitants to the evolving policies of the Spanish regime
The International Criminal Court in Self-Referral States: Legitimacy, Reputation, and the Court’s Anti-Impunity Mandate
No full textAs per its establishing treaty, the Rome Statute, the mandate of the International Criminal Court (ICC) is to end impunity for the crimes falling under its jurisdiction, i.e., genocide, crimes against humanity, war crimes, and crimes of aggression (ICC-level crimes). Concerning investigations initiated by a State Party to the Rome Statute referring a situation within their own territory to the ICC (self-referral states), the ICC has been criticized for only indicting rebel/ non-state actors when there is credible evidence that state elite were complicit in ICC-level crimes in the situations under investigation. This criticism has been detrimental to the ICC’s legitimacy with many victims of ICC-level crimes and general proponents of international criminal law. Previous research has convincingly found that the ICC’s apparent inability and/or unwillingness to indict state elite in self-referral states emerges from its dependence upon this elite for protection and access during its investigations, but this work posits that these choices also illustrate the ICC favouring its interest in its immediate survival over its interest in genuinely fulling its mandate. Further aggravating this criticism is the previously discovered tendency for the political regimes of these states to co-opt the ICC’s investigations to enhance their international legitimacy and other related interests in the face of fierce challenges to their holds on power. Paying particular attention to this problematically political reality, this work articulates an approach to potentially mitigate the legitimacy costs of the ICC’s case selection strategy in self-referral states. This approach involves the ICC taking advantage of the interests motivating the political regimes of self-referral states to co-opt the ICC’s investigations by leveraging the reputations of these regimes and their political elite to incrementally improve their states’ domestic judicial systems so that these systems might get to a point where they are eventually able and willing to prosecute ICC-level crimes genuinely and impartially themselves. At the center of this approach is the goal of creating an incentive structure to motivate this political elite to engage with strategies embodying the long-established concept of positive complementarity

No full textThe original print is faded. The output is the best quality possible at this time.(1) The chemical structure of Dextran II, the bacterial polysaccharide produced from sucrose by Leuconostoc mesenteroides, has been investigated by means of methylation studies, using improved methylation and fractional distillation techniques. (2) Highly-purified Dextran II has been shown to function as a haptene in precipitin reactions with anti-Leuconostoc sera. (3) The Haworth methylation technique has been modified and adapted generally to the synthesis of partially-methylated glucose derivatives. (4) 2,3-Dimethyl-ß-methyl glucoside and 2,3,4-trimethylglucose have been synthesized by new procedures developed by the author. Improvements have been made in the methods of synthesis of 2,3-dimethyl-, 2,3,4-trimethyl- and 2,3,4,6-tetramethyl methyl glucosides. [...
Re-examining HSPC1 inhibitors
No full text© 2017, The Author(s). HSPC1 is a critical protein in cancer development and progression, including colorectal cancer (CRC). However, clinical trial data reporting the effectiveness of HSPC1 inhibitors on several cancer types has not been as successful as predicted. Furthermore, some N-terminal inhibitors appear to be much more successful than others despite similar underlying mechanisms. This study involved the application of three N-terminal HSPC1 inhibitors, 17-DMAG, NVP-AUY922 and NVP-HSP990 on CRC cells. The effects on client protein levels over time were examined. HSPC1 inhibitors were also applied in combination with chemotherapeutic agents commonly used in CRC treatment (5-fluorouracil, oxaliplatin and irinotecan). As HSPA1A and HSPB1 have anti-apoptotic activity, gene-silencing techniques were employed to investigate the significance of these proteins in HSPC1 inhibitor and chemotherapeutic agent resistance. When comparing the action of the three HSPC1 inhibitors, there are distinct differences in the time course of important client protein degradation events. The differences between HSPC1 inhibitors were also reflected in combination treatment—17-DMAG was more effective compared with NVP-AUY922 in potentiating the cytotoxic effects of 5-fluorouracil, oxaliplatin and irinotecan. This study concludes that there are distinct differences between N-terminal HSPC1 inhibitors, despite their common mode of action. Although treatment with each of the inhibitors results in significant induction of the anti-apoptotic proteins HSPA1A and HSPB1, sensitivity to HSPC1 inhibitors is not improved by gene silencing of HSPA1A or HSPB1. HSPC1 inhibitors potentiate the cytotoxic effects of chemotherapeutic agents in CRC, and this approach is readily available to enter clinical trials. From a translational point of view, there may be great variability in sensitivity to the inhibitors between individual patients
