Abstract:

Visma Labs AB or Visma wanted to conduct experiments to see if file metadata could be indexed for searching files on a public cloud storage. Given that storing files in a public cloud storage is cheaper than the current storage solution, the implementation could save Visma money otherwise spent on expensive storage costs. The thesis is therefore to find and evaluate an approach chosen for indexing file metadata and searching files on a public cloud storage with the chosen distributed search engine Elasticsearch. The architecture of the proposed solution is similar to a file service and was implemented using several containerized services for it to function. The results show that the file service solution is indeed feasible but would need further tuning and more resources to function according to the demands of Visma. Visma Labs AB eller Visma ville genomföra experiment för att se om filmetadata skulle kunna indexeras för att söka efter filer på ett publikt moln. Med tanke på att lagring av filer på ett publikt moln är billigare än den nuvarande lagringslösningen, kan implementeringen spara Visma pengar som spenderas på dyra lagringskostnader. Denna studie är därför till för att hitta och utvärdera ett tillvägagångssätt valt för att indexera filmetadata och söka filer på ett offentligt molnlagring med den utvalda distribuerade sökmotorn Elasticsearch. Arkitekturen för den föreslagna lösningen har likenelser av en filtjänst och implementerades med flera containeriserade tjänster för att den ska fungera. Resultaten visar att filservicelösningen verkligen är möjlig men skulle behöva ytterligare modifikationer och fler resurser att fungera enligt Vismas krav.

Abstract:

Bubbles in water are stabilised against coalescence by the addition of salt. The white froth in seawater but not in freshwater is an example of salt-stabilised bubbles. A range of experiments have been carried out to investigate this simple phenomenon, which is not yet understood.¶ The process of thin film drainage between two colliding bubbles relates to surface science fields including hydrodynamic flow, surface forces, and interfacial rheology. Bubble coalescence inhibition also stands alongside the better known Hofmeister series as an intriguing example of ion specificity: While some electrolytes inhibit coalescence at around 0.1M, others show no effect. The coalescence inhibition of any single electrolyte depends on the combination of cation and anion present, rather than on any single ion.¶ The surfactant-free inhibition of bubble coalescence has been studied in several systems for the first time, including aqueous mixed electrolyte solutions; solutions of biologically relevant non-electrolytes urea and sugars; and electrolyte solutions in nonaqueous solvents methanol, formamide, propylene carbonate and dimethylsulfoxide. Complementary experimental approaches include studies of terminal rise velocities of single bubbles showing that the gas-solution interface is mobile; and measurement of thin film drainage in inhibiting and non-inhibiting electrolyte solution, using the microinterferometric thin film balance technique.¶ The consolidation of these experimental approaches shows that inhibiting electrolytes act on the non-equilibrium dynamic processes of thin film drainage and rupture between bubble surfaces and not via a change in surface forces, or by ion effects on solvent structure. In addition, inhibition is driven by osmotic effects related to solute concentration gradients, and ion charge is not important.¶ A new model is presented for electrolyte inhibition of bubble coalescence via changes to surface rheology. It is suggested that thin film stabilisation over a lifetime of seconds, is caused by damping of transient deformations of film surfaces on a sub-millisecond timescale. This reduction in surface deformability retards film drainage and delays film rupture. It is proposed that inhibiting electrolyte solutions show a dilational surface viscosity, which in turn is driven by interfacial concentration gradients. Inhibiting electrolytes have two ions that accumulate at the surface or two ions that are surface excluded, while non-inhibiting electrolytes have more evenly distributed interfacial solute. Bubble coalescence is for the first time linked through this ion surface partitioning, to the ion specificity observed at biological interfaces and the wider realm of Hofmeister effects.¶

Abstract:

À partir d'une analyse des prises de masse obtenues lors de croissance de nanotubes de carbone par CCVD suivie par micro-blance à quartz, un modèle cinétique est élaboré à l'échelle de la particule pour comprendre les mécanismes de la nucléation et de la croissance. Nous avons développé une étude des différentes étapes du procédé CCVD incluant une décomposition associative de l'hydrocarbure sur la face catalytique du catalyseur, la diffusion de surface et de volume du carbone, la nucléation et la croissance du nanotube résolue par une méthode de différences finies. Nos résultats indiquent très clairement que les processus de surface sont cinétiquement déterminants. La non-prise en compte des phénomènes à l'échelle atomique ne nous permet pas de prédire quelles sont les structures carbonées qui se forment pendant l'étape de nucléation ou de déterminer avec précision le chemin parcouru par un atome de carbone depuis la face catalytique jusqu'à son insertion dans le nanotube de carbone. Nous avons donc entrepris d'étudier la migration d'un atome de carbone depuis la surface du catalyseur jusqu'au plan graphitique constituant le nanotube de carbone à l’aide d’un code de calcul basé sur la méthode MEAM. La nouvelle génération de matériaux pour le stockage d'information nécessite la conception de réseaux réguliers ultra-denses de nanoparticules ferromagnétiques pouvant être synthétisés par méthode PE-CVD. Des simulations Monte-Carlo ont été effectuées pour sonder l'effet sur les propriétés magnétiques d'une augmentation de l'anisotropie des particules et/ou de la densité sur les capacités de stockage. Nos résultats montrent qu'un rapport d'aspect supérieur à 4 ne change pas fondamentalement les propriétés magnétiques du système et qu'avec de tels systèmes des capacités de stockage de l’ordre de 10 Tbits/inch² sont evisageables A kinetic model for the growth of carbon nanotubes is develloped based on experimental data obtained by TEOM-CCVD synthesis of CNTs. The model takes into account associative decomposition of hydrocarbon on the surface of the catlytic particle, surface and volume diffusion, nucleation and growth of CNTs solved by finite differnce method. The surfacic process seems to be the rate determining step. To take into account microscopic scale effects a MEAM based programm is developped to analyse the path followed by an atom of carbon from the the catalytic facet to the graphitic shell of the CNT to determine whether the diffusion is volumic, sub-surfacic or surfacic. An experimental method to obtain ultra-high density assemblies of ferromagnetic nanoparticles is the Plasma-Enhanced CCVD. Monte-Carlo numerical simulations are developped to analyse the magnetic properties of such devices. We show that an aspect ratio superior to 4 does not change the magnetic propreties of the system and that we could reach with such devices a density of 10 Tbits/inch², 20 times more than what is done at the moment

Abstract:

The tourism industry is vulnerable to crises and disasters and increasingly government and industry stakeholders are turning their attention to how to prevent, manage and recover from shock events. In the last decade there has been increasing interest in tourism research on crises and disasters, prompted in part by recognition of the tourism industry's vulnerabilities and what appear to be more frequent shock events. The beginning of this century has been marked by a series of crises and disasters including the 2001 Foot and Mouth Disease outbreak in the United Kingdom, the 2001 terrorist hijackings in the USA, the 2002 and 2005 Bali bombings, the 2003 SARS epidemic in southeast Asia and Canada, the 2004 Indian Ocean tsunami and Hurricane Katrina in the southern USA in 2005 (Henderson, 2007). The Intergovernmental Panel on Climate Change (2007a) has also predicted that the extreme weather events associated with climate change will lead to more natural disasters. Crises and disaster have local, regional and global repercussions on the tourism industry at business/corporate, industry and destination levels and the need for more attention to preparation, response and recovery is acknowledged. Much of the initial tourism research in this field focused on descriptions of crises and disasters and their impacts on tourism with some reflection on their management. This foundation and the comprehensive crisis and disaster literature from disciplines such as psychology, sociology, economics, geography and environmental science led to development of crisis and disaster management frameworks specifically designed for the tourism industry. These frameworks have achieved varying degrees of acceptance amongst tourism researchers with Faulkner and Vikulov's (2001) Tourism Disaster Management Framework (TDMF) being the most well known and often cited. The more recent Crisis and Disaster Management Framework (CDMF) developed by Ritchie (2004) is a useful destination-level framework based on a strategic management approach. Despite the development of these frameworks, relatively little tourism research effort has focused on destination recovery and very little on medium and long term recovery. In addition, there is little research on wildfires as a type of natural disaster. The extensive bushfires in the Australian Capital Territory (ACT) in 2003 (often referred to as the Canberra fires) provided an opportunity to investigate in a longitudinal study the short, medium and long term actions undertaken by the government and tourism industry to assist destination recovery and then compare them with Ritchie's prescriptive CDMF. Being longer term research this study is able to consider almost the entire recovery stage whereas other research has focused on short or medium term recovery (for example Faulkner & Vikulov, 2001). This research centred on a case study which is defined by Yin (1989 quoted in Wimmer & Dominick, 1997, p. 102) as an 'empirical inquiry that uses multiple sources of evidence to investigate a contemporary phenomenon within its real-life context'. This case study used interviewing, the documentary method and participant observation as the key methods. Representatives of government and the tourism industry were interviewed in-depth about the actions taken by their organisations or businesses. The interviews were semi-structured with mostly open-ended questions and some participants undertook multiple interviews over a three year period. Extensive secondary data and documentation about the bushfire and subsequent response and recovery was generated by the ACT government, industry and community and publicly available sources included reports and reviews, media releases, newspaper articles, newsletters, brochures, websites and legal and coronial enquiries. These were critical for gaining a comprehensive understanding of recovery. Participant observation was also important and, as a resident of the ACT, the author participated in relevant events and observed the public face of community recovery. The three methods resulted in a large data set that was distilled into a 'response and recovery story' structured according to Ritchie's CDMF. Upon comparing the findings with the framework, it was found that many elements were evident in the 'real life' case study including crisis communication, resource management, stakeholder communication, destination restoration and disasters as agents for change. There were also new findings that could be integrated into a redeveloped framework including the establishment of a recovery team, training for crisis and disaster management, tourist/visitor management, recovery planning, human resource management issues, business recovery tools, partnerships and memorialisation and commemoration. The resulting Tourism Industry Crisis and Disaster Management Framework (TICDMF) is a practical and comprehensive tool for Destination Management Organisations (DMOs) that both describes what occurred in a real life case study but also prescribes recommended management actions. In addition to specific recommendations for the ACT tourism industry, this research also resulted in general recommendations to the tourism industry, government and educators. These focused on (i) the importance of crisis and disaster management planning, (ii) the need to evaluate and document response and recovery and devote adequate resources to organisational learning, (iii) potential use of tools like the TICDMF and the plethora of resources to manage crises and disasters, (iv) educating staff, academics and tertiary tourism and hospitality students about crisis and disaster management and (v) accepting the chaos of recovery and devoting adequate resources to address the resulting complexity. The tourism industry is vulnerable to external shocks whether they be local crises or national disasters. The preparedness of the industry and its ability to effectively respond and recover is of critical importance for destinations and the community in which they function. Case studies of crises and disaster and development of a body of theoretical and practical knowledge will ensure that government and industry continue to play an important role in caring for the safety and security of tourists while maintaining a viable and sustainable industry for all stakeholders.

Abstract:

The work of documentary director Errol Morris can be approached in a variety of ways as it intersects and engages with many of the major themes of film and television scholarship - genre, authorship, and historical representation. But while his films and television episodes expose debates within film and documentary studies, they also call up major elements of postmodern debates within the historical discipline. Morris makes historical documentaries that do not simply render a (hi)story visually; he also attempts to draw viewers' attention to the conventions and construction of both visual media and of history. His work reveals both his keen awareness of postmodern historical debates, and a willingness to play, to confront basic assumptions, question boundaries, and to contribute to those debates. In 'Errol Morris and the Art of History', I argue that Morris is a visual historian; his films and television episodes draw as much from his understanding of historiographical debates as they do from his knowledge and artistic approach to visual media. All of Morris' work challenges the notion of objectivity in both documentary filmmaking and history; he attempts to illuminate the limits and conventions of visual depictions of history; he uses strategies to denaturalise historical and narrative construction, the naturalising tendencies of visual media, and the conventions of documentary practice; and he attempts to promote increased critical reflection. This thesis closely examines Morris' documentary films and television episodes to consider the structure and strategies that characterise his work, and situate it within contemporary film and historical debates. I explore Morris' methods and approach to documentary and history, showing how his work relates to postmodern history debates, to written and visual representations of history, and to documentary history and theory, including more recent factual forms like reality television.

Abstract:

La souche Pseudoalteromonas sp. NC201, isolée en Nouvelle-Calédonie, possède des propriétés antibactériennes et probiotiques dans le cadre d’élevages larvaires de crevettes. Ainsi, cette souche bactérienne constitue une alternative à l’utilisation des antibiotiques. Ce travail de thèse a été focalisé sur la caractérisation de NC201 et de son potentiel antimicrobien ainsi que sur l’étude de son effet sur la crevette, Litopenaeus stylirostris lors de challenges expérimentaux. L’analyse du génome de NC201 a révélé la présence de clusters de gènes codants des composés antimicrobiens ainsi que deux amino acides oxydases. Une de ces oxydases a été identifiée comme capable d’inhiber des Vibrio pathogènes de L. stylirostris. Les essais in vivo ont permis de confirmer le rôle probiotique de NC201. En effet NC201 a été responsable d’une amélioration de la survie des animaux lors de stress hypo et hypersalins mais aussi lors de challenge biotique par infection avec V. nigripulchritudo. Le suivi dans l’hémolymphe de NC201 et V. nigripulchritudo a mis en évidence que ces deux bactéries étaient capables individuellement de coloniser l’hémolymphe des animaux, cependant, une exclusion mutuelle des deux bactéries a été observée dans ce compartiment. L’expression de gènes liés à la réponse immunitaire ainsi qu’à la réponse au stress oxydant a été quantifiée suite au traitement probiotique et au challenge avec V. nigripulchritudo. La quantification et l’activité enzymatique de biomarqueurs du stress oxydant ont été mesurées. Les modulations de ces biomarqueurs ont révélé que la souche NC201 conférait aux crevettes un état de santé général plus performant pour répondre à des stress The Pseudoalteromonas sp. NC201 strain, isolated in New Caledonia, displayed antibacterial and probiotic properties in shrimp hatcheries. This strain is an alternative to antibiotics use. This thesis focused on the characterization of NC201, its antimicrobial potential as well as on the study on its effect on Litopenaeus stylirostris during experimental challenges. The analysis of the complete genome sequence of NC201 revealed multiple clusters coding for potential antimicrobial compounds as well as two amino acid oxidases. One of these oxidases was identified as capable of inhibiting Vibrio pathogenic to L. stylirostris such as V. penaeicida and V. nigripulchritudo. In vivo trials confirmed the probiotic role of NC201 towards L. stylirostris. Indeed NC201 was responsible for higher survival rates in animals confronted to hypo and hypersaline stress as well as to bacterial challenge through infection with V. nigripulchritudo. During experimental infections the presence of NC201 and V. nigripulchritudo was monitored in the shrimp hemolymph. Both bacteria are capable of invading the shrimp’s hemolymph but seemed mutually exclusive in this compartment during the 24 hours following the infection. The expression profile of genes involved in the immune response and the response to oxidative stress were quantified in the hemolymph and hepatopancreas, respectively. Enzymatic activities and quantification of bioindicators of oxydative stress were measured in the hepatopancreas. These modulations highlighted that NC201 induced an increase in the shrimp overall health status leading to enhanced responses to stresses

Abstract:

Résumé : Les films multicouches de polyélectrolytes constituent un nouveau moyen de changer la nature de l’interface entre un matériau et son environnement. Notre travail a consisté à développer de nouvelles façons de structurer ces films selon trois orientations différentes. Dans un premier temps, nous avons modifié la topographie de surface d’un film multicouche. Par une technique d’impression par compression nous avons transféré un motif microstructuré dans un film de (PDADMAC-PSS)20, à partir d’un tampon en polydimethylsiloxane. Les canaux longitudinaux et parallèles que nous y avons imprimés gardent leur morphologie et leur profondeur qu’ils soient conservés à sec ou dans une solution de NaCl à 0. 15M. Ces films microstructurés pourraient servir à guider la croissance cellulaire ou pour des applications en microfluidique. Dans une deuxième partie nous avons construit un film structuré en deux compartiments et nous l’avons fonctionnalisé avec des nanoparticules de dioxyde de titane. Les films stratifiés (PDADMAC-PSS)20-(PDADMAC-TiO2)n ont été obtenus par la méthode originale du dépôt réactif par nébulisation. Nos résultats montrent que des films hybrides riches en TiO2 acquièrent des propriétés de superhydrophilie photoinduite ainsi qu’une capacité à filtrer les rayons UV. Enfin, nous avons chargé en insuline des films de natures différentes à partir d’une solution aqueuse contenant cette molécule biologique. Nos expériences permettent d’envisager la délivrance de ce médicament au contact d’une solution imitant la salinité des fluides biologiques. Ces recherches ouvrent de nouvelles perspectives quant aux possibilités de « multifonctionnaliser » le revêtement d’un biomatériau Sumary : Polyelectrolyte multilayer films bring a new opportunity to change the nature of interactions between a material and its environment. Our study consisted in developping new functionalizations of these films in three different aspects. At first we modified the surface topography of a multilayer film. Through an embossing technique we transferred a microstructured pattern into a (PDADMAC-PSS)20 film from a polydimethylsiloxane stamp. The parallel, lengthwise channels we printed in it keep their morphology and their depth when stored in the dry state or in a NaCl 0. 15M solution. These microstructured films might be used for cellular guidance or for microfluidic applications. In a second part we built up a two-compartment structured film and functionnalized it with titane dioxide nanoparticles. The (PDADMAC-PSS)20-(PDADMAC-TiO2)n stratified films were obtained by an original reactive spray deposition method. Our results showed that hybrid films, enriched in TiO2, display photoinduced superhydrophilicity and exhibit a property to UV filtration. At last we loaded various kinds of films with insulin from a aqueous solution containing this biological molecule. Our experiments allowed us to expect drug release in a solution mimicking biological fluids. This study opens the route for easy and versatile multifunctionalization methods of biomaterial coatings

Abstract:

Figure minorée de l’histoire sociale, le colporteur a, de l’invention de l’imprimerie jusqu’à la révolution industrielle, parcouru des paysages aventureux, diffusant textes et images. Son activité a participé au développement de l’éducation populaire. Les « Modernes », soucieux d’échapper à la réiﬁcation, sensibles au renouvellement des attitudes et des discours, lui ont emboîté le pas. Pour nombre de ses représentants, il s’agit de privilégier la diffusion de l’imprimé comme activité artistique réelle et conséquemment, de susciter des situations – des stations de vie – composées de rencontres et de récits. Ce travail de thèse s’attache au développement des stratégies artistiques et poétiques dont la modestie formelle enrichit la complexité du contenu. De plus, s’il revient sur des signatures historiquement repérées (Albrecht/d., Marcel Broodthaers, Jef Geys, Ben Kinmont, Kurt Schwitters, Martha Rosler), il convoque aussi des initiatives anonymes ou collectives (Abandoned Letterhead, Continuous Project, la librairie des écrivains, L’in-plano, People’s Library). Une cartographie se dessine alors, un vagabondage où volontés militantes et sentiments mélancoliques se conjuguent Despite being a minor ﬁgure of social history, from the invention of the printing press to the industrial revolution, the pedlar has travelled through adventure-ﬁlled landscapes, spreading texts and images. His activities contributed to the development of popular education. The « Moderns », keen to escape concretization, and sensitive to the renewal of attitudes and discourses, did the same. For many of their representatives, the idea was to foster the dissemination of the printed matter as a true artistic activity and, consequently, to create situations – life steps – composed of encounters and stories. This thesis focuses on the development of artistic and poetic strategies whose formal modesty enriches the complexity of the content. In addition, while it reviews historically identiﬁed ﬁgures (Albrecht/d., Marcel Broodthaers, Jef Geys, Ben Kinmont, Kurt Schwitters, Martha Rosler), it also interrogates anonymous and collective initiatives (Abandoned Letterhead, Continuous Project, La Librairie des Écrivains, L’in-plano, People’s Library). Thus, a cartography, a vagrancy combining militant wills and melancholic feelings, emerges

Abstract:

There has been unprecedented growth in wireless technologies in recent years; wireless devices such as cellular telephones and wireless local area network (WLAN) transceivers are becoming ubiquitous. It is now common for a single hardware device, such as a cellular telephone, to be capable of multi-band operation. Implementing a dedicated radio frequency (RF) front-end for each frequency band increases the component count and therefore the cost of the device. Consequently, there is now a requirement to design RF and microwave circuits that can be reconfigured to operate at different frequency bands, as opposed to switching between several fixed-frequency circuits. Barium strontium titanate (BST) thin films show great promise for application in reconfigurable microwave circuits. The material has a high dielectric constant which can be controlled by the application of a quasi-static electric field, combined with relatively low losses at microwave frequencies. Tunable microwave components based on BST-thin films have the potential to replace several fixed components, thereby achieving useful size and cost reductions. This thesis is concerned with the growth and microwave circuit applications of BST thin films on c- and r-plane sapphire substrates. Sapphire is an ideal substrate for microwave integrated circuit fabrication due to its low cost and low loss. Electronically tunable capacitors (varactors) were fabricated by patterning interdigital electrode structures on top of the BST films. High capacitance tunabilities of 56% and 64% were achieved for the films grown on c-plane and r-plane sapphire, respectively, at 40 V bias. A novel electronically tunable 3 dB quadrature hybrid circuit was also developed. Prototypes of this circuit were initially implemented using commercial varactor diodes, in order to validate the design. An integrated version of the coupler was then fabricated using BST varactors on c-plane sapphire. The results achieved demonstrate the potential of sapphire-based BST thin films in practical microwave circuits.

Full text

Abstract:

TiN is used commercially as a wear resistant coating on cutting tools and as a diffusion barrier in microelectronics. TiN has gained increased interest as a material for MEMS, however there has been very little work carried out in the area of patterning and releasing TiN for use as a structural MEMS material. This thesis presents an investigation into the patterning and release of filtered arc deposited TiN thin films using surface micromachining techniques. Two novel strategies are presented for patterning TiN thin films and are achieved using excimer laser micromachining and photolithographic wet-etching. TiN was deposited onto single crystal Si and Cr and Cu sacrificial layers on Si. The use of Cr as a sacrificial layer was found to facilitate the best quality patterning of the TiN and hence the majority of the work involved using Cr sacrificial layers. TiN was deposited using partial filtration and full filtration and differences in the ability to selectively laser pattern the TiN from the Cr sacrificial layer are presented. Various analytical techniques were employed to investigate the origin of the difference in laser patterning the TiN thin films. The establishment of TiN and Cr as a novel material combination for surface micromachined MEMS was extended by etching the Cr sacrificial layer to facilitate the release of TiN stress-measurement structures. The major finding of this thesis is that filtered arc deposited TiN thin film on Cr can be used as a material combination to surface micromachine freestanding TiN structures as high quality patterning and etch selectivity can be achieved using both excimer laser micromachining and photolithographic wet-etching.

Abstract:

The medical documentary seeks to bridge the gap between the traditional imbalance of knowledge between the patient and her medical practitioner. This paper will examine the issue of the imbalance of the doctor and patient throughout the history of medicine, explore how the medical documentary seeks to solve this imbalance, and the methods by which it does so. By comparing three related medical documentaries and examining the strengths and weaknesses of each one in its attempt to educate and engage the viewer, I will seek to create a broad model for future medical documentaries and relate how my thesis film fits this new model.

Abstract:

This thesis contributes to the knowledge of how computer-mediated communication and information sharing works in large groups and networks. In more detail, the research question put forward is: in large sharing networks, what concerns do end-users have regarding to whom to provide material? A theoretical framework of gift-giving was applied to identify, label and classify qualitative end-user concerns with provision. The data collection was performed through online ethnographical research methods in two large sharing networks, one music-oriented and one photo-oriented. The methods included forum message elicitation, online interviews, application use and observation. The result of the data collection was a total of 1360 relevant forum messages. A part from this there are also 27 informal interview logs, field notes and samples of user profiles and sharing policies. The qualitative analysis led up to a model of relationships based on the observation that many users experienced conflicts of interest between various groups of receivers and that these conflicts, or social dilemmas, evoked concerns regarding public and non-public provision of material. The groups of potential recipients were often at different relationship levels. The levels ranged from the individual (ego), to the small group of close peers (micro), to a larger network of acquaintances (meso) to the anonymous larger network (macro). It is argued that an important focal point for analysis of cooperation and conflict is situated in the relations between these levels. Deepened studies and analysis also revealed needs to address dynamic recipient groupings, the need to control the level of publicness of both digital material and its metadata (tags, contacts, comments and links to other networks) and that users often refrained from providing material unless they felt able to control its direction. A central conclusion is that public and non-public gifting need to co-emerge in large sharing networks and that non-public gifting might be an important factor for the support of continued provision of goods in sustainable networks and communities.

Abstract:

Since the late seventies, the violence, speed and spectacle associated with the genres of war films, Westerns and the spectacular melodramas of early cinema have developed into a distinct genre of its own the action film. With the development of the stylistic language at the core of this generic universe came derogatory generalisations and a tendency to categorise simplistically. To overcome these simplifications, this thesis explores the shifts in generic language to distinguish its subtleties and complexities of logic. Overwhelmingly the genre is considered masculine, but the purpose of this thesis is to explore the logic of this masculinity and analyse the effect of the feminine upon it. Beginning with overviews of the theoretical attempts to grasp the concept of genre that focus primarily on the limitations of the view of their having distinct boundaries, the theory that genre theory has failed is investigated. Leaving this view of boundaries through an exploration of symbolic universes that have translucent boundaries, the filmic movement of genre passes back and forth through the theoretical frameworks. The intention is not to analyse the overall concept of genre, but to focus on the symbolic universe and the language intrinsic to action films. The rules of action cannot be simply transposed onto other generic categories but stand-alone. Genre theory does not fail if approached from a perspective of discourse analysis focusing on the development of symbolic universes. Using Jacques Lacans theory of the four discourses, and focusing primarily on the oppositions of the Masters and the Analysts discourse, the question moves from the listing of conventions as the markers of the boundaries of genre, to exploring why the combination of certain conventions and signifiers coming together created the genre. Through Lacanian discourse analysis it becomes apparent that the generally acknowledged logic of masculine and feminine are limited. The masculine is the norm that appears to need no explanation, but the feminine has transgressed the norm and shown the construction of fantasy inherent in the genre. This has led to post-action films that are ambiguous both in their generic structure and symbolic language.

Abstract:

Ce travail explore les rapports entre l'impression d'immobilité au cinéma et la croyance du spectateur, tant du point de vue des esthétiques (le traitement du son, la fixité du cadre et des acteurs, l'arrêt sur image et le filmage d'images fixes ), que des dispositifs. La première partie définit quatre catégories esthétiques de l'impression d'immobilité : le figement, le repos, l' apathéi͏̈a et l'inertie. La seconde partie analyse les rapports entre l'immobilité, l'idéologie et la croyance du spectateur. La troisième partie pose les bases d'une anthropologie culturelle de l'image en interprétant l'impression d'immobilité comme une réaction à une culture visuelle de masse marquée par le mouvement et la vitesse: on analyse l'exemple du cinéma underground (Fluxus, A. Warhol, H. Frampton, R. Smithson) comme le symptôme d'un désir de stabilisation du temps correspondant à une " volonté de puissance " de l'immobilité.

Apesar da sua importância, não foram verificados estudos e pesquisas acerca da desses fundos, bem como da natureza das ações por eles financiadas e o seu consequente impacto na garantia do acesso a níveis dignos de subsistência aos beneficiados. Assim, esta pesquisa assume por objetivo principal analisar as ações e programas financiados pelo FUNCEP no que tange a sua aderência com o marco legal do FUNCEP e o nível de convergência presente entre elas, bem como, descrever os desafios e oportunidades enfrentados pela gestão do FUNCEP na definição de uma metodológica que contribua para materializar, no cotidiano dos Órgãos executores ações financiadas por este Fundo, os conceitos de transversalidade, intersetorialidade e convergência, requeridos por temas multidimensionais e multideterminados como é o caso da pobreza, com ênfase especial aos anos de 2007 a 2009. Para tanto, realizou-se uma pesquisa exploratória sobre o conjunto de leis que conformam o marco legal do Fundo Estadual de Combate e Erradicação da Pobreza do Estado da Bahia – FUNCEP e o processo que pautou o funcionamento deste Fundo, tendo como foco as estratégias de seleção de programas, projetos e ações para o seu financiamento, bem como o perfil das ações financiadas. Foram utilizadas análises de documentos institucionais e legais, entrevistas com informações-chave e a técnica de observação participante, considerando que a autora deste trabalho ocupou o cargo de Diretora Executiva do Fundo de Combate e Erradicação da Pobreza do Estado da Bahia de janeiro de 2007 a janeiro de 2011. O resultado desse estudo mostra que o conjunto de ações financiadas pelo FUNCEP não alcançou o nível esperado de articulação entre seus diversos órgãos executores, diluindo deste modo o potencial necessário ao enfrentamento da pobreza. Conclui-se, com esse estudo, que as inovações implantadas pelo FUNCEP constituem avanços na direcionalidade das ações financiadas e na nstrução de estruturas de governança para a formulação e execução destas, restando estabelecer os instrumentos e mecanismos a fim de operacionalizar tais avanços.

Abstract:

Thin polymer films and their properties have been investigated. The characteristics of crystalline polymers according to film thickness have been improved using polycaprolactone (PCL). The melting enthalpy of PCL has increased when the film thickness decreased and the peak melting temperature showed no significant changes with film thickness. Film thickness variation influenced surface roughness and crystal size. Optical microscope images showed the rougher surface of thicker films. The spinning time has shown no influence on film thickness and no significant changes to surface roughness. Thin films of block copolymers were used in the surface modification study; films studied included poly(styrene-b-butadiene-b-styrene) (SBS) and poly(styrene-b-isoprene-b-styrene) (SIS) and their surface modifications have been controlled using different methods of treatment. Films of SIS heated at different temperatures have shown different surface texture and roughness. Films treated at low temperature (45 °C) had smooth surfaces when compared with films heated at high temperature (120 °C and 160 °C). Phase separation of SIS heated at (120 °C and 160 °C) caused bulges of different sizes to cover the surface. The height and width of the bulges showed variation with film thickness and heating. Substrate interaction with SBS and SIS block copolymer films showed different surface texture when using the same type of substrate and different texture were obtained when SBS solutions were spun onto different substrates. It has been demonstrated that using different solvents in copolymer preparation caused different texture. Thermal and surface property variations with film thickness have been improved using amorphous polymers. Surface roughness of poly(methyl methacrylate) PMMA and disperse red 1-poly(methyl methacrylate) DR1-PMMA, PMMA has improved using thickness variation. Glass transition temperature measurement has increased when film thickness was increased. The glass transition temperature (Tg) and surface roughness of UV15 UV - curable coating polymer has been modified using UV curing and heating methods. Tg variation was observed when curing time and curing intensity were changed causing the optical properties of the polymer to be more variable. A plasma etcher caused wrinkles to occur on the surface of unheated UV15. Tg of UV15 increased when curing time increased. The Fourier Transform Infrared Spectroscopy (FTIR) spectra of cured UV15 film have shown peak variations of the ester and carbon double bond regions over the range of 1850-1700 cm-1. Urethane-Urea (UU) Polymer thin films were used to investigate optical properties and develop an optical waveguide. Absorption and transmission properties of light using non-linear optical (NLO) polymer was investigated and used in optical waveguide fabrication. Refractive indices were measured to examine UU films at two different wavelengths. A UU film of 1 µm thickness caused a maximum absorption at max = 471 nm also obtained at 810 nm wavelength. Many methods of fabrication were used; photolithography, plasma etching in a barrel reactor and thin film deposition using sputtering and evaporation. Etched depths from 1 μm to 100 μm were obtained. An optical waveguide has been prepared using plasma etching of a cured UV15 as a cladding layer on a silicon substrate.

Abstract:

Thin film coatings are used to improve the properties of components and products in such diverse areas as tool coatings, wear resistant biological coatings, miniature integrated electronics, micro-mechanical systems and coatings for optical devices. This thesis focuses on understanding the development of intrinsic stress and microstructure in coatings of the technologically important materials of aluminium nitride (AlN) and titanium vanadium nitride (TiVN) deposited by filtered cathodic arc deposition. Thin films of AlN are fabricated under a variety of substrate bias regimes and at different deposition rates. Constant substrate bias was found to have a significant effect on the stress and microstructure of AlN thin films. At low bias voltages, films form with low stress and no preferred orientation. At a bias voltage of -200 V, the films exhibited the highest compressive stress and contained crystals preferentially oriented with their c axis in the plane of the film. At the highest bias of -350 V, the film forms with low stress yet continue to contain crystallites with their c axis constrained to lie in the plane of the film. These microstructure changes with bias are explained in terms of an energy minimisation model. The application of a pulsed high voltage bias to a substrate was found to have a strong effect on the reduction of intrinsic stress within AlN thin films. A model has been formulated that predicts the stress in terms of the applied voltage and pulsing rate, in terms of treated volumes known as thermal spikes. The greater the bias voltage and the higher the pulse rate, the greater the reduction in intrinsic stress. At high pulsing and bias rates, a strong preference for the c axis to align perpendicular to the substrate is seen. This observation is explained by dynamical effects of the incident ions on the growing film, encouraging channelling and preferential sputtering. For the first time, the effect of the rate of growth on AlN films deposited with high voltage pulsed bias was investigated and found to significantly change the stress and microstructure. The formation of films with highly tensile stress, highly compressive stress and nano-composites of AlN films containing Al clusters were seen. These observations are explained in terms of four distinct growth regions. At low rates, surface diffusion and shadowing causes highly porous structures with tensile stress; increased rates produced Al rich films of low stress; increasing the growth rate further led to a dense AlN film under compressive stress and the highest rates produce dense, low stress, AlN due to increased levels of thermal annealing. Finally this thesis analyses the feasibility of forming ternary alloys of high quality TiVN thin films using a dual cathode filtered cathodic arc. The synthesised films show exceptional hardness (greater than either titanium nitride or vanadium nitride), excellent mixing of the three elements and interesting optical properties. An optimum concentration of 23% V content was found to give the highest stress and hardness.

Abstract:

Sous climat humide tropical ou subtropical, les processus d'altération supergène sont les principaux responsables de la formation et de la libération des fibres d'amiante dans l’environnement. Plus du tiers de la Nouvelle Calédonie est recouvert d’unités ultrabasiques altérées, riches en minerai de Ni. L’exploitation minière du Ni doit composer avec la présence d’affleurements d’amiante et de minéraux fibreux de type serpentine et amphibole. Dans ce contexte, les sociétés minières doivent prévenir les risques sanitaires liés à l'exposition environnementale aux fibres minérales. Actuellement, il n'existe pas de technique analytique capable de caractériser instantanément une fibre d'amiante in situ, en fournissant des informations sur la distribution de taille, la morphologie, la composition chimique et le degré d'altération associés. Cependant, la connaissance de tous ces paramètres est nécessaire pour évaluer le risque sanitaire associé à l'exposition. L'utilisation des dispositifs portable tels quels la Microscopie Optique à Lumière Polarisée (MOLP) et la spectrométrie Raman représente la stratégie la plus efficace pour améliorer l'acquisition et l'interprétation des données, y compris pour les échantillons fortement fibreux et altérés. De plus, des analyses géochimiques préliminaires ont révélé que l'effet mécanique de la circulation des fluides entre les fibres et lamelles, associé à la lixiviation chimique des éléments à l'interface roche/eau, favorisent la dissociation des fibres et leur libération dans l'environnement. Un focus a été réalisé sur l'antigorite fibreuse, reconnue comme amiante uniquement dans la réglementation calédonienne Under humid tropical to sub-tropical conditions, weathering processes and supergene mineralization are the main responsible for genesis and release of asbestos fibres. The New Caledonia is one of the largest world producers of Ni ore that is formed by the alteration of ultramafic rocks. Almost all outcrops of geological units and open mines contain serpentine and amphibole, also as asbestos varieties. Mining companies must therefore deal with the health concerns related to environmental exposure to mineral fibres. At present, there is not a technique capable to instantly characterize an asbestos fibre in situ, providing information about size and distribution, morphology, chemical composition and alteration grade. However, the acquisition of all these parameters is necessary for determining the health risk associated to fibre exposition. The employment of specialized tools such as Polarized Light Microscopy associated to Dispersion Staining (PLM/DS) and portable Raman spectroscopy has proved extremely effective in the improvement of performance and rapidity of data acquisition and interpretation, even in the presence of strongly fibrous and altered samples. Regardless of the alteration state, a great variability in morphology was observed (SEM investigation). Preliminary geochemical analyses have proved that the physical-mechanical effect of fluid circulation within the porous of fibres and lamellae, associated to chemical elemental exchange at rock/waters interface, favoured the dissociation of fibres and their release in the environment. A focus was set on fibrous antigorite, recognized as asbestos only by Caledonian legislation, but still not by European law

La macrofaune benthique des rivieres est dominee par les insectes. Les milieux les plus propices au developpement de la macrofaune benthique et qui presentent la diversite specifique maximale sont les ruisseaux forestiers. A l'oppose, les cours d'eau drainant des peridotites alterees et eloignees de toute occupation humaine se caracterisent par des peuplements benthiques moins diversifies et moins abondants dus a leur faibles teneurs en matieres organiques. En outre, certains taxons presentent un endemisme generique et specifique lie au substrat peridotitique a l'instar des insectes terrestres. Une biotypologie des stations d'etude a ete definie, fondee sur les memes criteres que ceux de la typologie physico-chimique. L'occupation des sols, la vegetation rivulaire et la nature geologique des bassins versants representent les principaux facteurs expliquant la repartition et la distribution de la macrofaune benthique des rivieres. Un indice biotique original specifique aux rivieres de nouvelle-caledonie est propose dans ce travail. L'indice biotique de nouvelle-caledonie (ibnc) permet de detecter des pollutions organiques en milieu courant.

Abstract:

The research focuses on public opposition to the extension of South East New Territories (SENT) Landfill in Tseung Kwan O, Hong Kong. The phenomenon of opposing undesirable facilities sitings is described as the “Not in my backyard (NIMBY)” syndrome in literature and the popular media. SENT Landfill is expected to reach its saturation capacity before 2016 but the public opposition has been fierce to prohibit the extension proposal. The objectives of this study is to identify how the public in Tseung Kwan O perceive the landfill extension proposal, reasons for opposing the extension and potential measures to resolve the conflicts. A questionnaire survey was adopted to obtain both quantitative and qualitative data. One-hundred fifty samples were collected from each sampling area. A total of four-hundred fifty samples were collected among three sampling areas in Tseung Kwan O. It was found that residents who live in Lohas Park are strongly against the proposal of SENT landfill extension due to the close proximity of Lohas Park to the landfill. Respondents with higher levels of knowledge about the landfill extension issue have a higher chance to accept the proposal. It was concluded that the residents in Tseung Kwan O are mostly unsatisfied with inadequate or ineffective public involvement in the existing policy-making process. The government should consider dropping its centralized planning approach and reforming current information-giving channels. Officials should also make efforts to enhance their credibility by cooperating with environmental NGOs. published_or_final_version Environmental Management Master Master of Science in Environmental Management

This thesis analyses the effect of the personal history of Arthur and Corinne Cantrill, two Australian independent filmmakers, on their style of filmmaking. It analyses their representation of film-form experimentation within national Australian art in a range of independent film works. It reflects on their cultural relation to the general history of independent filmmaking in Australia, America and Europe. It studies the circumstances tat resulted in the appearance of the Cantrills' experimental film and their relation to international art theories and film experimentation. This thesis will examine how the Cantrills' film works, which were often critical of conventional filmmaking styles, and their critical writing, statements and promotion of their independent and experimental film work contributed significantly to theoretical discussion and argument about the physical nature of film within Australia. This examination is explored through asking and answering the central question: The work of Aurtheur and Corinne Cantrell is theoretically drawn from a tradition of European arts and visually drawn from Australian landscape and urban culture; can their work be identified and undertood as Australian art?

Abstract:

Nous avons utilisé des simulations de dynamique moléculaire pour étudier des films ultra-fins de polymères, à l'aide d'un modèle coarse-grained. Nous avons analysé la dynamique au sein du film, aussi bien en moyenne que par couches en fonction de la distance à la surface. Nous avons déterminé la température de transition vitreuse Tg au cours de refroidissements. Il ressort de ces études que la dynamique est accélérée dans les couches minces par rapport à la situation du fondu en volume, et Tg diminue. Des films de polymères en solution ont également été étudiés en présence d'un solvant explicite. Nous nous sommes intéressés à la formation de films de polymères purs par évaporation du solvant; les résultats obtenus montrent que la dynamique est plus rapide et Tg plus basse en présence du solvant. Alors que nous pouvons observer une diffusion fickienne à des températures supérieures à Tg, pour des températures plus basses, les déviations par rapport à ce comportement sont notables.

Abstract:

Privacy in the workplace will be a significant legal and policy issue in employment during the late 1990's. The impact of computer technology in employment highlights privacy concerns and issues and is particularly acute in public school employment. Public schools have a right to know information about teachers which relates to their fitness in working with children. At the same time, teachers have a legitimate expectation of privacy, especially as it applies to their professional reputations and their abilities to maintain or obtain future employment in teaching. This study had two purposes. One was to determine the extent of computer usage for personnel files in Virginia public schools, and the existence of policies and nature of practices for the management of data maintained in such a fashion through a survey of all school divisions in Virginia. The other was to make recommendations to assist public school divisions in the establishment or revision of management policies and practices governing computerized personnel files, after a thorough review of applicable sources of federal and state law. The study found that 83% of all public school divisions in Virginia responding to the survey use computers to maintain at least one category of personal information about their teachers. The categories of data range from contract information to employee assistance programs. School divisions use a variety of computer formats (i.e., mainframes, minicomputers, PCs) for these purposes. The results of the survey demonstrate that not all school divisions have written policies in place, or training of staff, or security mechanisms for their computer systems necessary for compliance with state statutes. These statutes, the Freedom of Information Act, the Privacy Protection Act, and the Computer Crimes Act, delineate the legal responsibilities of school divisions in the areas of employee privacy and management of personal information. The study concludes with specific recommendations for the areas of written policy, staff training, and system security.

Abstract:

Cette these interroge les relations entre les documentaires de creation, leur espace de realisation et la visee spectatorielle des institutions impliquees dans la production ou la diffusion. La recherche est centree sur la prevision du spectateur: d'une part par les actants de l'espace de realisation (auteurs, realisateurs, techniciens), d'autre part par les institutions (producteurs, commanditaires, diffuseurs divers, dont les chaines de televisions). Les concepts de spectateur et de lecture du film sont deplaces en amont de la diffusion traditionnelle afin de considerer une succession d'"horizons d'attente" lors des etapes qui vont de la decision de production a l'achevement de l'oeuvre filmique. Les reactions spectatorielles etudiees sont en premier lieu celles de professionnels du cinema ou de la television qui s'accordent ou s'opposent sur l'effet produit, ou sur l'effet a produire, chez le spectateur final. Les documentaires realises par l'auteur de la these, et leurs declinaisons par les institutions, servent de corpus de base. La chaine des professionnels (scenariste, realisateur, producteur, cadreur, monteur, etalonneur, mixeur, diffuseur etc) en s'imposant une lecture d'equipe induit un texte filmique et l'oriente plus ou moins sciemment vers un standard, un type suppose universel de subjectivite, a moins que l'instance personnelle du realisateur ne s'attache a resingulariser le propos et son expression. Ces pratiques prospectives et les conflits de lectures du reel qui en resultent sont analyses a la lumiere de deux theories de la reception: la theorie de la lecture litteraire, "la lecture comme jeu", de michel picard qui situe l'activite lectorielle dans l'aire transitionnelle de winnicott, et la semio-pragmatique de roger odin qui propose une analyse de la participation des institutions a la reception des films This reception theory-based dissertation investigates the relationship between creative documentaries, the film-making process they involve, and the spectator envisioned by the institutions which produce or broadcast them. The spectator reactions studied are primarily those of cinema or television professionals who either agree or disagree on the effect produced or to be produced on the traditional end-of-the-line spectator. The documentaries made by the author of the dissertation, along with their adaptations by various institutions, serve as a basis for the research. By imposing upon themselves a team-reading, the chain of professionals (film-maker, producer, cameraman, director of photography, editor, broadcaster, etc. ) invents a filmic text and orients it more or less consciously toward a standard product - whose subjectivity is supposed universal -, unless the film-maker makes a particular effort to personalize his work. The reception theories on which the analysis of these practices is based are michel picard's literary theory of "reading as play", which situates reading in winnicott's transitional space, and roger odin's semio-pragmatic theory which proposes an analysis of institutional involvement in the reception of films

Abstract:

The present study aimed to determine whether stable isotope techniques can be universally applied to detect landfill leachate contamination in aquatic systems. Results of analysis of ��C in dissolved inorganic carbon ([delta]��C-DIC), deuterium and �⁸O in water ([delta]D-H₂O and [delta]�⁸O-H₂O), and �⁵N of dissolved inorganic nitrogen components ([delta]�⁵N-NH₄⁺ and [delta]�⁵N-NO₃⁻) were presented for leachate, surface, and ground water samples collected from seven landfills located throughout New Zealand between 2003 and 2006. The unique conditions within a landfill lead to measurable fractionations in the isotopic ratios of the products of degradation. Results of isotope and ancillary parameter analyses enabled the discernment of different types of leachate, resulting from different microbial processes within the landfill environment. The isotopic characterisation of leachate enabled improved interpretation of geochemical data from potentially impacted surface and ground waters, and provides useful insight to landfill development for landfill operators. A general isotopic fingerprint delineated by [delta]��C-DIC and [delta]D-H₂O values showed leachate to be isotopically distinct from uncontaminated surface and ground water for samples analysed in the present study. However, not all water samples identified as leachate-impacted via site-specific assessments exhibited isotopic values that overlapped with the general leachate fingerprint. This highlights the need to investigate each site individually, within the context of a possibly global leachate isotope signature. Site-specific investigations revealed the effectiveness of applying [delta]�⁸O-H₂O and [delta]�⁵N-NH₄⁺ or [delta]�⁵N-NO₃⁻, in addition to [delta]��C-DIC and [delta]D-H₂O analyses, to the detection of leachate impact on aquatic systems. Furthermore, ancillary parameters such as alkalinity and ammonium concentration enabled the construction of simple isotope mixing models for an estimate of the quantity of leachate contribution. Results of isotopic investigations of stream biota suggested potential for the development of bio-indicators to monitor leachate influence on aquatic ecosystems in landfill-associated streams. The present study demonstrated the probative power of stable isotope techniques applied to investigations of leachate impact on landfill-associated aquatic systems.

The performance was evaluated by applying data envelopment analysis where first an efficiency frontier for the group of analyzed entities is calculated based on linear programming and second, for every hospital, its respective distance from the efficiency frontier for each factor analyzed is calculated. The data collection for this analysis was obtained through interviewing with a structured questionnaire. However, the quality of the collected data proved to be rather limited. Hence the results of the analysis should be seen as rather indicative how data envelopment analysis could be used to evaluate the performance of hospitals, than to drive conclusion on the performance of the respective hospital or organizational model. By applying data envelopment analysis, we were able to identify best practice hospitals within the analyzed group and to identify the dimensions underperforming hospitals may improve. A second intention was to analyze if one of the two organization models applied in the public hospitals in Bahia, the traditional public or outsourcing organization model differ in terms of efficiency. In concept, data envelopment may be helpful to identify such differences regarding performance, nevertheless, the analysis of the analyzed group of hospitals returned mixed results. Salvador

Abstract:

Dans le domaine des biomatériaux, les films de multicouches de polyélectrolytes représentent une nouvelle voie possible de modification de surface : Ces films sont édifiés par adsorption successive de polyanions et de polycations. Dans le cadre de cette étude, nous avons travaillé sur différents types de films pour d'une part caractériser leurs propriétés physico-chimiques par spectroscopie optique par guide d'onde, par microbalance à cristal de quartz, par microscopie confocale et par la microscopie à force atomique et d'autres part pour étudier les interactions des cellules avec les films. Une première partie de mon travail a consisté à caractériser les films élaborés à base de poly(L-Lysine) et d'acide poly(L-Glutamique). Plusieurs paramètres de constructions ont été testés (pH, taux de sels, nombres de couches déposées). L'adsorption de protéines sériques sur les films a également été évaluée, de même que l'adhésion cellulaire à court terme par des expériences de micromanipulation. Dans une deuxième partie, nous nous sommes focalisés sur des films à base de polysaccharides, notamment le chitosan et le hyaluronan. Après avoir caractérisé la croissance et la structure de ces films, nous avons ensuite étudié la propriété d'adhésion vis à vis des cellules et des bactéries. Nous avons notamment mis en évidence qu'une rigidification chimique des films change considérablement les propriétés d'adhésion cellulaire: la réticulation des films augmentant l'adhésion cellulaire.

Abstract:

La fonctionnalisation de surfaces permet de modifier les propriétés d’un matériau. C’est dans ce cadre que s’incrit la construction de films multicouches de polyélectrolytes qui repose sur l’adsorption alternée de polyanions et de polycations sur une surface chargée. Le travail de thèse présenté dans ce manuscrit vise le développement d’un nouveau procédé pour le dépôts de ces polyélectrolytes : la nébulisation. Un dispositif automatique de nébulisation de polyélectrolytes a été réalisé et utilisé pour étudier :la construction de films de poly(acide glutamique)/poly(allylamine) par nébulisation simultanée, et la croissance de films multicouches d’acide hyaluronique/poly(lysine)(HA/PLL) à croissance exponentielle. Il a ainsi été observé que la croissance de multicouches (HA/PLL) est seulement exponentielle lorsque l’épaisseur du film est inférieure à 200 nm à sec. Au delà, la croissance devient linéaire. Un modèle dit en « 3 zones » est proposé expliquer ce comportement Various techniques have been developed to coat solid substrates by thin organic films starting with liquid solutions or dispersions. For the last two decades, the layer by layer (LbL) polyelectrolyte deposition technique has recieve a constant attention. It consists in the alternate deposition of polyanions and polycations on solid surface leading to the formation of polyelectrolyte multilayers (PEMs). In this manuscript, we developed a new way to deposit PEMs by a spraying process. An automated spraying device was built and used to study:the film construction by spraying simultaneously and continuously a poly(glutamic acid) and a poly(allylamine),and the growth of an exponential growing PEM of poly(L-lysine) and hyaluronic acid (PLL/HA). We observed that the film growth undergoes a transition between an exponential to a linear regime when the film thickness is up to 200 nm in the dry state. A model in “3 zones” is discussed to explain the growth mechanism of such films

Abstract:

In this work, a series of simple, rapid and effective photoelectrochemical methodologies have been developed and successfully applied to the study of kinetic and thermodynamic characteristics of photocatalytic oxidation processes at TiO2 nanoparticulate films. As an application of the systematic studies of photocatalytic processes by photoelectrochemical techniques, a rapid, direct, absolute, environmental-friendly and accurate COD analysis method was successfully developed. In this work, the TiO2 nanoparticles colloid was prepared by the sol-gel method. The TiO2 nanoparticles were immobilized onto ITO conducting glass slides by dip-coating method. Thermal treatment was carried out to obtain nanoporous TiO2 films of different structures. At low calcination temperature (below 600°C), nanoporous TiO2 films of pure anatase phase were prepared. At high calcination temperature (above 600°C), nanoporous TiO2 films of mixed anatase and rutile phases were obtained. At these film electrodes, the work was carried out. By employing steady state photocurrent method and choosing phthalic acid as the model compound, the photocatalytic activity of the TiO2 nanoporous films calcined at various temperatures and for different lengths of time was evaluated. It was found that the films with mixed anatase and rutile phases calcined at high temperature exhibited high photocatalytic activity. Based on semiconductor band theory, a model was proposed, which explained well this finding. By employing linear sweep voltammetry (under illumination) and choosing glucose (an effective photohole scavenger) as a model compound, the characteristics of the photocatalytic processes at nanoparticulate semiconductor electrodes were investigated. Characteristics of the nanoporous semiconductor electrodes markedly different from bulk semiconductor electrodes were observed. That is, within a large range of electrode potentials above the flat band potential the electrodes behaved as a pure resistance instead of exhibiting variable resistance expected for bulk semiconductor electrodes. The magnitude of the resistance was dependent on the properties of the electrodes and the maximum photocatalytic oxidation rate at TiO2 surface determined by the light intensity and substrate concentration. A model was proposed, which explained well the special characteristics of particulate semiconductor electrodes (nanoporous semiconductor electrodes). This is the first clear description of the overall photocatalytic process at nanoparticulate semiconductor electrodes. The investigation set a theoretical foundation for employing photoelectrochemical techniques to study photocatalytic processes. By using the transient technique (illumination step method analogous to potential step method in conventional electrochemistry), the adsorption of a number of strong adsorbates on both low temperature and high temperature calcined TiO2 nanoporous films was investigated. Similar adsorption characteristics for different adsorbates on different films were observed. In all the cases, three different surface bound complexes were identified, which was attributed to the heterogeneity of TiO2 surface. The photocatalytic degradation kinetics of the pre-adsorbed organic compounds of different chemical nature was also studied by processing the photocurrent-time profiles. Two different photocatalytic processes, exhibiting different rate characteristics, were observed. This was, again, attributed to the heterogeneity of the TiO2 surface corresponding to heterogeneous adsorption characteristics. The catalytic first order rate constants of both fast and slow processes were obtained for different organic compounds. It was found that for different adsorbates of different chemical nature the magnitudes of rate constant for the slow kinetic process were very similar, while the magnitudes of rate constant for the fast process were significantly affected by the photohole demand characteristics of different adsorbates. Photohole demand distribution that depends on the size and structure of the adsorbed molecules was believed to be responsible for the difference. By employing steady state photocurrent method, the photocatalytic degradation kinetic characteristics of both strong adsorbates and weak adsorbates of different chemical structures were compared at pure anatase TiO2 nanoporous TiO2 films as well as at anatase/rutile mixed phase TiO2 nanoporous film electrodes. At the former electrodes for all the different organic compounds studied, the photocatalytic reaction rate increased linearly with concentration at low concentrations. Under such conditions, it was demonstrated that the overall photocatalytic process was controlled by diffusion and was independent of the chemical nature of organic compounds. However, the linear concentration range and the maximum photocatalytic reaction rate at high concentrations were significantly dependent on the chemical nature of the substrates. This was explained by the difference in the interaction of different organic compounds with TiO2 surface, the difference in their photohole demand distributions at the TiO2 surface and the difference in their nature of intermediates formed during their photocatalytic mineralization. In contrast, at the latter electrodes for the photocatalytic oxidation of different organic compounds the linear ranges (diffusion control concentration range) and the maximum reaction rates at high concentration were much larger than at the former electrodes and much less dependent on the chemical nature of the organic compounds. The spatial separation of photoelectrons and photoholes (due to the coexistence of rutile phase and anatase phase) and the increase in the lifetime of photoelectrons and photoholes are responsible for the excellent photocatalytic activity of the electrodes. By employing the thin-layer photoelectrochemical technique (analogous to the thin-layer exhaustive electrolytic technique), the photocatalytic oxidation of different organic compounds at the mixed phase TiO2 nanoporous electrodes were investigated in a thin layer photoelectrochemical cell. It was found that the charge derived from exhaustive oxidation agreed well with theoretical charge expected for the mineralisation of a specific organic compound. This finding was true for all the compounds investigated and was also true for mixtures of different organic compounds. The photocatalytic degradation kinetics of different organic compounds of different chemical identities in the thin layer cell was also investigated by the photoelectrochemical method. Two kinetic processes of different decay time constants were identified, which were attributed to the degradation of preadsorbed compounds and the degradation of compounds in solution. For the degradation of compounds in solution, a change in the overall control step from substrate diffusion to heterogeneous surface reaction was observed. For different organic compounds, the variation of the rate constant was determined by the photohole demand rather than by the chemical identities of substrates. The kinetics of the fast kinetic process, on the other hand, was greatly affected by the adsorption properties of the substrates. For the strong adsorbates, the rate was much larger than for weak adsorbates. However, the rate constant of the process was independent of the chemical identities of the substrates and the variation of the constant was also determined by the photohole demand. Based on the principles of exhaustive photoelectrocatalytic degradation of organic matter in a thin layer cell, a novel, rapid, direct, environmental-friendly and absolute COD analysis method was developed. The method was tested on synthetic samples as well as real wastewater samples from a variety of industries. For synthetic samples with given compositions the COD values measured by my method agree very well with theoretical COD value. For real samples and synthetic samples the COD values measured by my method correlated very well with those measured by standard dichromate COD analysis method.

Abstract:

Le caséinate de sodium (CS) possède des propriétés fonctionnelles particuliérement intéressantes. Le CS a été choisi comme matière première pour l'étude et la mise au point de films comestibles. La fabrication des films homogènes, transparents et flexibles est basée sur la dispersion du CS en milieux aqueux et l'incorporation des plastifiants (e. G. Glycérol, sorbitol). La solution filmogène a été évaluée, ainsi que les propriétés d'hydratation, les propriétés barrière à l'eau et aux gaz, la résistance mécanique, le comportement thermique et optique des films. En parallèle, des études structurales (microscopie électronique à balayage, microscope environnemental, rugosité et RMN) ont été aussi exécutées pour expliquer des transferts de vapeur d'eau liés à la mobilité des protons. Les propriétés thermiques du système CS-plastifiant-eau ont été caractérisées par l'analyse enthalpique différentielle modulée (MDSC) et l'analyse thermomécanique dynamique (DMTA). La perméabilité à la vapeur d'eau des films de CS augmente proportionnellement avec la teneur en plastifiant et des variations de l'humidité relative ambiante. Les films CS - sorbitol étaient plus perméables que les films CS - glycérol. L'effet de l'humidité relative sur la perméabilité au C02 et à l'02 a été démontrée. Ainsi, cette augmentation se traduit par une diminution des propriétés barrière à la vapeur d'eau, de la résistance mécanique et du module d'élasticité des matériaux, qui peut être reliée aux variations de la température de transition vitreuse du CS. Ces observations sont attribuées aux différences de masse molaire et à la quantité de groupements hydrophiles qui règle les interactions protéine - plastifiant et protéine - protéine dans le film. La température de transition vitreuse des films de CS plastifiés par de l'eau, du glycérol ou du sorbitol a été modélisée selon le modèle de Couchman - Karasz ; un comportement linéaire a été obtenu pour décrire l'effet plastifiant sur une base molaire.

Tais transformações foram direcionadas pelo pensamento neoliberal que passou a orientar a reestruturação produtiva do Estado capitalista baseado no diagnóstico de que a crise se limitava a uma crise fiscal do Estado, daí a necessidade de se empreender reformas econômicas, políticas, fiscais, sociais, etc, no sentido de se atingir o equilíbrio fiscal. No Brasil, estes direcionamentos se aprofundaram nos anos 90, com reflexos sobre as políticas sociais. Neste trabalho, busca-se compreender os direcionamentos e a natureza de tais políticas, na referida década, a partir de uma revisão bibliográfica das concepções contemporâneas do capitalismo no trato das questões sociais, objetivando compreender as opções adotadas pelo Estado brasileiro. Tomando como base a análise de que não é o Estado que está em crise, de que há uma crise mais ampla que atinge o sistema capitalista, pode-se compreender melhor a ênfase dada às políticas sociais assistencialistas.
