Eigen-value Analysis

description: A general eigen-value buckling solution is developed for the buckling of long thick pipes subjected to internal and external hydrostatic pressure. The principle of stationary potential energy is used to formulate the conditions of equilibrium, neutral stability conditions, and associated boundary conditions using polar coordinates. The formulation accounts for shear deformation effects and is suited for composite pipe systems with thick cores. It involves destabilizing terms: one is due to the external hydrostatic pressure and incorporates the follower effects, and the other, is due to the pre-bucking stresses undergoing the nonlinear components of strains. The formulation adopts a work conjugate triplet consisting the Cauchy stress tensor, the Green Lagrange strain tensor, and constant constitutive relations. A Fourier series expansion of the displacement fields is adopted to transform the 2D problem into a series of independent 1D problems, thus keeping the computational effort to a minimum while preserving the accuracy of the solution. Two numerical solutions were developed and implemented under MATLAB; the first one is based on the finite difference technique and the second one is based on the finite element solution. Both solutions were shown to converge to the same solution, the finite difference from below, while the finite element converges from above. The finite element solution is then applied to predict the buckling capacity of sandwich pipes consisting of two steel pipes with a soft core. A comprehensive verification study is conducted and the validity of the formulation was established through comparison with other solutions. A parametric study is then conducted to investigate the effect of hydrostatic internal pressure, core material, core thickness, and internal and external pipe thicknesses, on the external buckling pressure of sandwich pipes.
FoxO3a Modulates the Activation of Innate and Adaptive Immune Cells

Dendritic cells

description: The innate immune response mediates immediate control of the pathogen and is followed by the acquired immune response which is slower but ensures comprehensive elimination of the pathogen. Dendritic cells are unique innate immune cells that can phagocytose the pathogen and generate pathogen-associated antigenic peptides for presentation to T cells in order to initiate the acquired immune response. Dendritic cells also express cytokines which facilitate pathogen control and development of acquired immune responses, thus acting as a bridge between innate and acquired immune responses. CD8+ T cells are important cells of the adaptive immune system that play a key role in mediating clearance and protection against intracellular pathogens. Upon engagement by antigen-presenting cells, CD8+ T cells undergo massive expansion followed by a swift, extensive contraction to restore homeostasis. The mechanisms behind the expansion and contraction of CD8+ T cells are yet to be completely elucidated. FoxO3a is a transcription factor that is involved in the regulation of various vital cellular processes ranging from cell proliferation and cell metabolism to stress resistance and cell death. I have, therefore, investigated the role of FoxO3a signaling in the activation of dendritic cells and CD8+ T cells. My initial experiments indicated that FoxO3a regulates the homeostasis of various immune cells including CD8+ T cells and dendritic cells. CD8+ T cells lacking FoxO3a displayed enhanced proliferation, as evaluated by cell imaging, CFSE dilution and Ki67 staining, upon polyclonal stimulation in vitro. The modulation of cell proliferation by FoxO3a seemed to be p27kip-independent, as evaluated by western blotting. At later stages of stimulation, FoxO3a-deficient CD8+ T cells underwent reduced cell death, as assessed by cell counting and 7-AAD staining, and this seemed to be independent of Bim, Caspase 8 or Caspase 3 activation. In addition, FoxO3a regulated cytokine expression by CD8+ T cells while displaying similar NFκB activation in comparison to WT CD8+ T cells. Similar results were observed in dendritic cells upon LPS stimulation in vitro, wherein cytokine expression was higher in the FoxO3a-deficient dendritic cells and they also displayed enhanced antigen presentation to CD8+ T cells, as evaluated by CFSE dilution. Taken together, these results indicate that FoxO3a acts as a negative regulator of CD8+ T cell and dendritic cell activation.

description: Many companies have sought to adopt the approaches used by entrepreneurs in small companies to achieve growth and performance improvement. The field of corporate entrepreneurship investigates the strategies that are successfully used by such companies and the benefit that they enjoy from using those strategies. One area that appears to have attracted limited attention is how a company’s board of directors influences its corporate entrepreneurship initiatives. This paper presents research that explores how entrepreneurship is influenced by Boards of Directors at large publicly listed Australian commercial banks. A model based on Krueger’s construct of Entrepreneurial Potential is proposed and tested. The research uses a case study methodology and involves analysis of in-depth interviews with members of the Boards of Directors of four banks. The data supports the model and the shows a positive association between the construct Board Entrepreneurial Potential and Corporate Entrepreneurship. The authors propose that if a company is to be entrepreneurial, the attitudes and perceptions of its Board must be changed either before or as a consequence of management’s actions.

description: An ethnopharmacological survey was carried out between December 2012 and May 2013 in eleven different locations dependent on the Guercif Province (NE of Morocco). The names of plants, their mode of preparation and administration, and their parts used have been inventoried for various local uses in traditional medicine. Our survey allowed us to identify one hundred plant species used in that Province, belonging to 49 botanical families. Rosmarinus officinalis, Origanum compactum, Artemisia herba-alba, Thymus spp., Mentha pulegium, Nigella sativa, Lavandula spp., Visnaga daucoides, Aristolochia longa and
Cenchrus spicatus are the most used taxa by the local population. This study showed that the plant leaves are the most commonly used parts, and the remedies prepared are mostly based on decoction. The endocrine system, especially the diabetes, and the digestive one are the most frequent among the body systems treated by the local traditional medicine.

description: The concentration-dependent absorption behaviour of uranium was investigated with surviving intestinalsegments of rat jejunums, using an ex-vivo model. The results showed a monotonic slightly nonlinearincrease in absorption as uranium concentrations increased. This trend was observed over the entire concentrationrange tested. In the lower concentration range a slower linear ascent was observed while asteeper linear ascent was found for the higher concentration range. Statistical fit was only slightly poorerfor an exponential function in the range of lower values and a logarithmic function in the range of highervalues. The proportion of uranium absorbed expressed as percent of uranium concentrations in the perfusionsolutions followed a monotonically increasing trend from 20 to around 200 lg/l uranium in theperfusion solutions, which thereafter appears to reach a plateau, as further increase towards concentrationsaround 400 lg/l is not substantial. The uranium concentration administered had no effect on thevitality and consequently the functionality of the intestinal segments, measured in terms of active glucosetransport. The results imply that uranium concentrations of more than 20 lg/l in drinking water,for example, could lead to elevated absorption rates and thus to higher internal exposures to considerwhen setting of Guideline values in this concentration range.Quelle: http://www.sciencedirect.com

description: 125 years after its first publication, the international language Es-peranto is not only alive and well, but the number of its speakers is on theincrease. While globalization has often been blamed for the demise of minority languages and dialects, this phenomenon has actually been advanta-geous for Esperanto. Thanks to radio and television, newspapers, magazines,and above all, the Internet, Esperanto speakers from all over the world areable to contact one another and make use of the language. Just as in the pasttelevision contributed to the development of Italian as a national language,in the same way the modern means of communication, in addition to nume-rous international conferences and other events, have contributed to the de-velopment of new idioms in Esperanto, putting into effect what the authorsdescribe as a genuine “process of humanization”. In this article the authorslist over a hundred idiomatic expressions in Esperanto, comparing them witha similar number of expressions from English, French, Italian and modernGreek. It can clearly be seen how Esperanto tends to adopt expressions whichare widely used at the international level, expressing them in the simplest andmost logical form. Since many of them are Biblical or literary in origin, andare shared by numerous languages and peoples, they can be understood atonce, even when the languages are not closely related.

Subjects: subject: Computer Science.

description: The focus of software engineering has traditionally been oriented toward new software construction inspite of the fact that very substantial costs arise in the maintenance phase of the software lifecycle. A key element in the maintenance phase is "program understanding" because the individuals assigned this task are typically distinct from those on the development team. Tools to assist with program understanding have, nevertheless, received only modest attention in recent years. In this thesis the topic is explored within the context of the development of a particular program understanding tool called PUMP. PUMP (Program Understanding Tool for MODSIM Programs) is a tool developed to help understand simulation models written in the object-oriented simulation language called MODSIM programs. It has a simple graphical user interface (GUI) and may be used for both system exploration and for browsing purposes as part of a professional software development tool. It quickly displays and provides views of complex inheritance trees, making it an important tool for understanding object-oriented systems.

Les hypothèses ont tenté de ressortir les habiletés de gestion précises qui sont reliées au succès managérial, c'est à dire un rendement supérieur, un taux d'absentéisme bas et une progression de carrière rapide. L'organisation où les données ont été recueillies compte 2200 employés dont 650 cadres et 1550 employés de diverses catégories de métiers. Un total de 503 cadres de l'entreprise (n = 503) dont 320 hommes et 76 femmes ont été sélectionnés. Les données ont été recueillies entre 1980 et 1989 (mais 51.2% ont été recueillies en 1980). Cinq cent (500) formulaires d'évaluation de rendement complétés obtenus du service des ressources humaines ont été compilés. Les commentaires au sujet de la performance ainsi que des échelles d'évaluation ont permis de discerner quatre cent trois (403) comportements spécifiques positifs ou négatifs. La deuxième étape visait à identifier de ces 403 comportements, ceux ayant le plus d'importance pour le succès général en gestion. (Abstract shortened by UMI.)

description: Blasmusik – insbesondere von Laien gespielte – gilt in der breiten Bevölkerung oft als verstaubt, altmodisch, militärisch, langweilig oder bieder. Nichtsdestotrotz ist sie aus dem kulturellen und sozialen Leben vieler Ortschaften, speziell im ländlichen Raum, kaum wegzudenken. Blasmusikvereine unterstützen durch die Aufstellung von Jugendensembles die musikalische Ausbildung von Kindern und Jugendlichen, ermöglichen als partizipative Musizierpraxis allen Menschen – unabhängig ihrer musikalischen Fähigkeiten – einen Raum, um gemeinsam Musik zu machen und bieten der Bevölkerung lokale musikalische Unterhaltung an Altersheimständchen, Platzkonzerten, Umrahmungen von weltlichen und kirchlichen Anlässen sowie eigenen Auftritten. In den 2‘136 Gemeinden der Schweiz existierten Anfang 2023 1‘862 dem Schweizer Blasmusikverband (SBV) angehörende Vereine; von den 8‘815‘385 Einwohner:innen des Landes gehörten 54‘606 (0,6 Prozent) einem solchen an.
Trotz ihrer wichtigen gesellschaftlichen Funktionen und scheinbaren Omnipräsenz werden Blasmusikvereine von der Wissenschaft kaum wahrgenommen. Zudem sehen sich die Vereine seit der Jahrtausendwende mit einem zunehmenden Mitgliederschwund konfrontiert. Mittels einer repräsentativen Umfrage sowie Interviews in fünf Beispielvereinen gibt der Author einen Überblick über die Blasmusikszene des Kantons Bern im beginnenden 21. Jahrhundert. Anschliessend erarbeitet er im Sinne der angewandten Ethnomusikologie konkrete Lösungsansätze für die aufgezeigten Schwierigkeiten gemäss Prinzipien der kulturellen Nachhaltigkeit. Zentral scheint dabei insbesondere die partizipative Natur der Ensembles sowie ihr Umgang mit gesellschaftlichen Veränderungen.

description: Background: Previous publications indicated an emerging issue with community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA), particularly skin and soft tissue infections (SSTIs), in Indigenous communities in Canada. The objectives of this analysis were to explore the prevalence of SSTIs due to CA-MRSA and patterns of antimicrobial use in the community setting. Methods: A retrospective chart review was conducted as part of an environmental scan to assess antibiotic prescriptions in 12 First Nations communities across five provinces in Canada including Alberta, Saskatchewan, Manitoba, Ontario, and Québec. Charts were randomly selected from nursing stations and patients who had accessed care in the previous 12 months and were ≥ 18 years were included in the review. Data was collected from September to December, 2013 on antibiotic prescriptions, including SSTIs, clinical symptoms, diagnostic information including presence of CA-MRSA infection, and treatment. Results: A total of 372 charts were reviewed, 60 from Alberta, 70 from Saskatchewan, 120 from Manitoba, 100 from Ontario, and 22 from Québec. Among 372 patients, 224 (60.2%) patients had at least one antibiotic prescription in the previous 12 months and 569 prescriptions were written in total. The prevalence of SSTIs was estimated at 36.8% (137 cases of SSTIs in 372 charts reviewed). In 137 cases of SSTIs, 34 (24.8%) were purulent infections, and 55 (40.2%) were due to CA-MRSA. Conclusions: This study has identified a high prevalence of antibiotic use and SSTIs due to CA-MRSA in remote and isolated Indigenous communities across Canada. This population is currently hard to reach and under-represented in standard surveillance system and randomized retrospective chart reviews can offer complimentary methodology for monitoring disease burden, treatment and prevention.

description: This thesis examines how mental hygiene principles were adopted for a student audience through the elementary-level health textbooks series, Health and Personal Development, used in Ontario schools from 1952 until 1963. In particular, I explore the didactic messages pertaining to mental hygiene as they related to girls. The results of this analysis demonstrate that healthy mental hygiene and personal development for girls, according to the textbooks, meant becoming wives, mothers, and homemakers, as their own mothers model. While these roles required many skills and responsibilities, and provided women with a certain amount of agency in the female-dominated sphere, girls were represented in the textbooks as having a limited set of options in life: to emulate their mothers’ feminine domesticity, or to risk a life marred by poor mental hygiene.

description: Objective: 1) Systematic review on the accuracy of Chronic Rhinosinusitis (CRS) identification in administrative databases; 2) Develop an administrative data algorithm to identify CRS patients who have endoscopic sinus surgery (ESS). Methods: A chart review was performed for all ESS surgical encounters at The Ottawa Hospital from 2011-12. Cases were defined as encounters in which ESS for performed for Otolaryngologist-diagnosed CRS. An algorithm to identify patients who underwent ESS for CRS was developed using diagnostic and procedural codes within health administrative data. This algorithm was internally validated. Results: Only three studies meeting inclusion criteria were identified in the systematic review and showed inaccurate CRS identification. The final algorithm using administrative and chart review data found that encounters having at least one CRS diagnostic code and one ESS procedural code had excellent accuracy for identifying ESS: sensitivity 96.0% sensitivity, specificity 100%, and positive predictive value 95.4%. Internal validation showed similar accuracy. Conclusion: Most published AD studies examining CRS do not consider the accuracy of case identification. We identified a simple algorithm based on administrative database codes accurately identified ESS-CRS encounters.

description: The effects of segmental length as well as anterior rib cage and costovertebral joint integrity on thoracic spinal stability have not been extensively investigated, but are essential for the calibration and validation of numerical models of the thoracic spine and rib cage. The aim of the study was to quantify these effects by in vitro experiments. Eight human thoracic spine specimens (C7-L1) including the rib cage were loaded with pure moments of 5 Nm in flexion/extension, lateral bending, and axial rotation while tracking the motions of all functional spinal units. Specimens were tested stepwise in four different conditions: (1) In the intact condition, (2) after cutting all anterior rib-to-rib connections, (3) after partitioning the polysegmental specimens into monosegmental specimens, and (4) after removing the ribs in the monosegmental condition. Significant increases of the range of motion (p < 0.05) were especially found at the segmental levels of the upper half of the thoracic spine in all motion planes and for all resection steps, particularly in axial rotation, while the stabilizing effects of the structures decreased in inferior direction. Partitioning of polysegmental specimens into monosegmental specimens primarily affected the stability in lateral bending, while the effects of resection were generally lowest in flexion/extension. Presence of the ribs, anterior rib cage integrity, and segmental length all affect the thoracic spinal stability and have therefore to be considered in the calibration process of numerical models of the thoracic spine and rib cage.

description: The antibacterial behaviour of ZnO nanopowder and their composite coatings were investigated against E. Coli. ZnO nanopowder and Aluminum based ZnO composite powders were synthesized using in-house powder processing techniques. Bacteria culture results showed that ZnO nanopowder and their composite powders displayed excellent bacteriostatic activity against E. coli. The antibacterial activity increased with increasing concentration of ZnO nanoparticle in their composite powders as well as increasing surface area of compacted pellets. These nanocomposite powders were subsequently used to generate antibacterial coatings using cold spray technology. The ratio of Al to ZnO in their composite powders were 80:20, 50:50 and 20:80 (wt.%). Microstructural characterization and phase analysis of feedstock powders and as-deposited coatings were carried out using FESEM/EDX and XRD. Antibacterial nanocomposite Al-ZnO coatings were successfully deposited using cold spraying parameters of 15 Bars at air temperature of between 200-300 degrees C. These assprayed coatings of Al-ZnO composite powders with varying Al and ZnO ratios retained their inherent antibacterial property as verified from bacterial counting test. The results indicated that the antibacterial activity increased with increasing ZnO nanopowder concentration in the composite powder feedstock and cold sprayed coating.

description: We present a theoretical study of the interplay between cyclotron motion and spin splitting of charge carriers in solids. While many of our results apply more generally, we focus especially on the Rashba model describing electrons in the conduction band of asymmetric semiconductor heterostructures. Appropriate semiclassical limits are distinguished that describe various situations of experimental interest. Our analytical formulae, which take full account of Zeeman splitting, are used to analyse recent magnetic-focusing data. Surprisingly, it turns out that the Rashba effect can dominate the splitting of cyclotron orbits even when the Rashba and Zeeman spin-splitting energies are of the same order. We also find that the origin of spin-dependent cyclotron motion can be traced back to Zitterbewegung (ZB)-like oscillatory dynamics of charge carriers from spin-split bands. The relation between the two phenomena is discussed, and we estimate the effect of ZB-related corrections to the charge carriers' canonical position. © In Copyright http://rightsstatements.org/vocab/InC/1.0/

description: Childcare is a critical target for promoting children’s physical activity (PA) and physical literacy (PL). With emerging evidence about the efficacy of policy and capacity-building strategies, more information about how to bring these strategies to scale is needed. This paper describes implementation at scale of Appetite to Play (ATP), a capacity-building intervention for childcare providers, and examines the implementation and impact on early years providers’ capacity to address PA. The ATP implementation evaluation was a natural experiment that utilized a mixed methods concurrent parallel design framed within the Reach, Effectiveness, Adoption, Implementation, Maintenance framework (RE-AIM). Workshop and website tracking assessed reach and adoption. Surveys and interviews with workshop participants and stakeholders assessed satisfaction, implementation, and maintenance. Training reached 60% of British Columbia municipalities and 2700 early years providers. Significant changes in participants’ knowledge and confidence to promote PA and PL were achieved (p > 0.01–0.001). Childcare level implementation facilitators as reported by early years providers included appropriate resources, planning, indoor space, and equipment, whereas weather and space were reported barriers. The stakeholder advisory group viewed the stakeholder network and Active Play policy as facilitators and adjustments to recent shifts in childcare funding and previous initiatives as barriers to implementation. ATP was scalable and impacted provider knowledge, confidence, and intentions. The impact on actual policies and practices, and children’s PA needs to be assessed along with sustainability.

description: Sin dall’antichità ed a partire da una molteplicità di prospettive differenti, la storia del pensiero filosofico e scientifico e costellata da tentativi reiterati di individuare una strutturazione più o meno sistematica di porzioni di realtà. Uno dei punti di partenza fondamentali e spesso stato lo studio, la ricerca e la messa a pun-to di linguaggi irreggimentati – adeguati e non ambigui – che fungessero da ideale cornice concettuale di lavoro per esplicitare le loro proprietà e strutture. Tuttavia, lo stesso dibattito sull’individuazione di quella characteristica universalis che rimanda`ad un’indagine piu approfondita sulle basi e le finalità teoriche che risultano costitutivi di tale dibattito: il caso esemplare che si vuole presentare e quello delle assun-zioni ontologico-metafisiche retrostanti al «programma logicista» di Gottlob Frege, all’interno alle dispute filosofico-matematiche di fine Ottocento, nella costruzione diun linguaggio formale che permettesse di rilevare ed estrinsecare in modo precisole basi logiche del ragionamento (e dello stesso linguaggio naturale) per poter dare fondamento adeguato alla matematica. A cio verrà contrapposta la presentazione di una panoramica del sistema formale di Stanislaw Leśniewski (mereologia estensionale), che prende avvio da assunzioni teoriche opposte e si orienta verso una profonda revisione metafisica sia delle entità che la teoria va a trattare, che della loro concettualizzazione.

description: We investigate ionization and high harmonic generation (HHG) from the interaction of a mid infra-red laser pulse with a solid state system confined to nano-dimensions. The theory of strong field processes in solids is developed for confined quantum systems in general. Here it is applied to two-dimensional quantum wires with a driving field linearly polarised along the axis of the wires. Our findings indicate that that we are able to control the ionization and high-harmonic output by altering the width of the wire. Control of ionization leads to an increased damage threshold which has important implications for nano-engineering and realizing all solid state coherent XUV sources.

English-Canadian literary anthologies

description: The dissertation investigates the correlations among the development of general anthologies of Canadian literature, the Canadian canon, and visions of national identity. While literature anthologies are widely used in university classrooms, the influential role of the anthology in the critical study of literature has been largely overlooked, particularly in Canada. The dissertation begins with an analysis of the stages of development of general anthologies of Canadian literature, demonstrating that there are important links between dominant critical trends and the guiding interests of the various phases of anthology development and that anthologies both reflect and participate in moulding views of the nation and its literature. Focusing then upon five eighteenth- and nineteenth-century Canadian authors, the dissertation traces their treatment in anthologies and analyzes in detail the impact of stages of anthology development upon authors’ inclusion and presentation. The reception of Frances Brooke, John Richardson, William Kirby, Susanna Moodie, and Emily Pauline Johnson over a span of nearly 90 years is examined, and points of inclusion and exclusion are scrutinized to determine links with prevailing critical interests as well as canonical status. These case studies reveal the functions of anthologies, which include recovering overlooked authors, amending past oversights, reflecting new areas of critical inquiry, and preserving the national literary tradition. Their treatment also reveals the effect of larger critical concerns, such as alignment with dominant visions of the nation, considerations of genre, and reassessments of past views. The dissertation shows that the anthology is a carefully constructed, culturally valuable work that plays an important role in literary criticism and canon formation and is a genre worthy of careful scrutiny.

description: The exceedance of critical loads is a measure to determine whether current political regulations and actions are sufficient to protect the environment from harmful effects of air pollutants. The pollution of ecosystems was one of the reasons for updating the legally-binding regulations on air pollution control in Europe, e.g. the Directive 2016/2284 on national emission ceilings for certain atmospheric pollutants (NEC Directive) adopted in 2016.

description: Increasing demands in radar sensor performance for automotive applications require reliable test solutions for the development and verification. In this paper, a modulation-based radar target simulator suitable for automotive settings is presented. A cost-effective circuit with low complexity is proposed that modulates the radar signal directly in the E-Band without an intermediate frequency stage. Models are derived for predicting the limitations of such radar target simulators due to hardware nonidealities. The introduced radar target simulator is analyzed with respect to the derived nonidealities in order to predict its performance based on the models. As a verification, radar measurements with the target simulator are conducted, and compared with the models' predictions.
Computer science without computers: new outreach methods from old tricks

description: A disturbing gap is emerging as the demand for qualified computer scientists increases, yet enrolments in CS courses have dropped dramatically since 2000. One of the reasons often given for this is the mismatch between what school students understand the subject to be, and what it really is. A major project based at Canterbury University is underway for school outreach to communicate to primary-school aged children what sort of ideas computer scientists work with. To avoid confusing the message with the medium, the programme does not use computers at all, but instead uses activities, games, magic tricks and competitions to show children the kind of thinking that is expected of a computer scientist. The project, dubbed 'CS Unplugged', has recently enjoyed widespread adoption internationally, and substantial industry support. It is recommended in the ACM K-12 curriculum, it has influenced the official Korean school curriculum, and has been translated into Korean and Japanese with approximately 10 more translations in progress. The Unplugged outreach materials are freely available on the web, and new formats and activities are under development. This includes adaptations of the kinaesthetic activities for special needs children (including mobility and vision impairment); integration with other outreach tools such as the Alice language, and videos to help teachers understand how to use the material. This paper will explore why the programme is generating so much interest, and describe developments and adaptations that are being used for outreach around New Zealand as well as internationally.

description: Substantial enhancement of the activity of Ru/γ‐Al2O3 catalyst for the methanation of CO2 results from an unusual modification of the metal–support interaction between Ru nanoparticles (NPs) and γ‐Al2O3, which causes a significant increase of support basicity and restructuring of Ru NPs from hemispherical to flat. image. Ru/Al2O3 is a highly stable, but less active catalyst for methanation reactions. Herein we report an effective approach to significantly improve its performance in the methanation of CO2/H2 mixtures. Highly active and stable Ru/γ‐Al2O3 catalysts were prepared by high‐temperature treatment in the reductive reaction gas. Operando/in situ spectroscopy and STEM imaging reveals that the strongly improved activity, by factors of 5 and 14 for CO and CO2 methanation, is accompanied by a flattening of the Ru nanoparticles and the formation of highly basic hydroxylated alumina sites. We propose a modification of the metal–support interactions (MSIs) as the origin of the increased activity, caused by modification of the Al2O3 surface in the reductive atmosphere and an increased thermal mobility of the Ru nanoparticles, allowing their transfer to modified surface sites.

description: Although the opera paraphrase was once a cornerstone of the virtuoso pianist's repertoire, as a genre it has traditionally been neglected by a scholarship which prioritizes authenticity and original compositional thought. By approaching this repertoire from a critical standpoint concerned with the production of narrative, this thesis demonstrates the true value of the paraphrase. A review of the current literature on narrative, gesture, and the paraphrase reveals major gaps in the state of research, and this thesis addresses these issues by presenting analyses of several works, in both printed and performed forms. The chapter “Settling the Score” interrogates the score, and argues that through their choice, ordering, and setting of operatic themes in a paraphrase, composers can alter or recreate the narrative of the source opera. By analyzing and comparing by reading the narrative schemes of seven different paraphrases based on Mozart's Don Giovanni, the chapter highlights the agency of the arranger in the production of narrative. The next chapter, entitled “Playing the Part,” suggests that the creation of narrative also extends beyond the work of the composer to encompass the role of the performer. By comparing the use of physical gestures in two video-recorded performances of Liszt's paraphrase Réminiscences de Don Juan, the thesis postulates that a pianist's gestures can influence the audience's perception of narrative. In an attempt to centralize the voice of the performer, the chapter also includes reflective analysis of the author's own performances of Liszt's paraphrase. By employing analytical methods which focus on the production of musical narrative, this thesis demonstrates that the paraphrase is worthy of greater attention, both in scholarship and performance.
