Bifurcated by a demilitarized United Nations Buffer Zone since 1974, Nicosia is the only divided capital city in Europe. In 1979, its dual municipalities devised a radical, bicommunal Master Plan to mitigate some of the buffer zone’s divisionary effects and to revitalize the city center. This thesis examines the role of historic preservation within the Nicosia Master Plan, investigating the development of the plan’s preservation element and evaluating how the rehabilitation and adaptive reuse of historic buildings on either side of the barrier have promoted peaceful interaction and spurred economic growth and resettlement in the central city. Population growth, the booming heritage tourism industry, and the proliferation of bicommunal cultural events all indicate the successful implementation of these strategies. Of interest to preservationists, planners, and policymakers faced with divisive and nontraditional planning challenges, this is a timely topic that reveals the potential for preservation strategies to effect lasting urban revitalization.

CAPES / A quitosana é um polímero abundante e oriundo principalmente de crustáceos a qual vem sendo amplamente estudada em vários segmentos inclusive como coberturas comestíveis de frutas. Frutas e hortaliças sofrem com a ação do clima, insetos e injurias do pós colheita; atentos a isto, pesquisadores vem estudando e desenvolvendo coberturas comestíveis que protejam a integridade dos vegetais. As coberturas de quitosana podem ser funcionalizadas com outros compostos que melhorem as suas características bem como a sua resistência pode ser aumentada com o uso de agentes reticulantes. / Chitosan is an abundant polymer and derived mainly on crustaceans which has been widely studied in various segments including as edible fruit toppings. Fruits and vegetables suffer from climate action, insects and injuries of post harvest; aware of this research has been developing and studying edible coatings that protect the integrity of the plants. The chitosan covers can be functionalized with other compounds that improve its characteristics and its strength can be increased by the use of crosslinking agents. / 5000

This thesis examines the city of Nanjing in the context of challenges to its sustainability and preservation represented by contesting forces in play in its rapid urbanization and redevelopment. These contesting forces are represented in a discourse matrix that illustrates the tensions between holism and economic development on one axis and contested interpretations of intrinsic values and place-based associations of residents on another. These tensions, which are present in many historic preservation cases across the globe, are made very specific by the administrative structure of preservation in China and in the city in tension with the pressures of conventional redevelopment that destroys historic fabric. At issue are losses of authenticity in the life of the city as understood by the associations of residents with their places of residence. This tension is exacerbated by the cultural and difficult political history of Nanjing, which can be understood to embody its intrinsic history. This history is recounted here to provide context for the evaluation of two city preservation projects, the Ming City Wall and the South Old Town preservation districts in relation to the discourse matrix. Conclusions are offered which suggest that only the future will reveal how Nanjing will or will not resolve these tensions between holistic preservation and government-controlled redevelopment.

The three-dimensional digital preservation of real objects comprises two main aspects: the preservation of the shape of the object and the preservation of its appearance. This thesis focuses on the image-based appearance preservation of real objects and provides a set of contributions on the theme. The first contribution consists in two groups of experiments, where each one of them targets one different image-based appearance preservation approach. These experiments are based in fundamental concepts related to the behavior of light and in a compilation of works that aim to preserve the appearance of real objects using different types of images. The first group of experiments attempts to disregard as much as possible the influence of the environment light. The second one goes one step further and considers a single light source. These experiments were the basis and motivation for the development of the main contribution of this thesis, which is a novel image-based appearance preservation method that considers the whole environment as a source of light. It presents as novelty the fact that it estimates the incoming light from the whole environment to each point in an object surface patch. At the best knowledge of this work, none of the current existing methods adopts this approach. Considering the whole environment as source of light allows flexible acquisition setups and, as it reproduces what happens in reality, potentially retrieves more reliable information about the incident lighting. This thesis presents this method and its application on real and synthetic environments. Conclusions about this work are presented and future research directions are discussed._________________________________________________________________________________________ RESUMO: A preservação tridimensional digital de objetos reais compreende dois aspectos: a preservação da forma do objeto e a preservação de sua aparência. Esta tese tem como foco a preservação da aparência de objetos reais baseada em imagens e provê uma série de contribuições sobre o tema. A primeira contribuição consiste em dois grupos de experimentos, onde cada um trabalha uma abordagem diferente na preservação da aparência baseada em imagens. Esses experimentos são baseados em conceitos fundamentais relacionados ao comportamento da luz e em uma compilação de trabalhos que visam preservar a aparência de objetos reais usando diferentes tipos de imagens. O primeiro grupo de experimentos tenta desconsiderar ao máximo a inuência da luz. O segundo vai um passo além e considera uma única fonte de luz. Estes experimentos são a base e motivação para o desenvolvimento da principal contribuição desta tese, que é um novo método de preservação da aparência baseado em imagens que considera todo o ambiente como fonte de luz. Ele apresenta como novidade o fato de estimar a luz vinda de todo o ambiente para cada ponto em uma região na superfície de um objeto. Até onde foi pesquisado neste trabalho, nenhum método existente adota essa abordagem. Considerar todo o ambiente como fonte de luz permite configurações flexíveis durante a aquisição e, já que reproduz o que acontece na realidade, recupera informações potencialmente mais confiáveis sobre a iluminação incidente. Esta tese apresenta este método e sua aplicação em ambientes reais e sintéticos. Conclusões sobre este trabalho são apresentadas e direções futuras de pesquisa são discutidas.

Pharmaceutical and cosmetic preparations must be formulated so as to assure elegance of appearance, efficacy of ingredients and a satisfactory shelf life as the product. If the formulation is not self-preserving and if it contains material which could act as a substrate for growth of micro-organisms, the shelf life aspect involves, in addition to several other factors, the choice of a suitable antimicrobial preservative. Such preservatives, when present in the minimum effective concentration, are unfortunately prone to interact with many other materials. A number of papers on the inactivation of preservatives by containers, filters and formulation components have been published. The field has been adequately reviewed by de Navarre (1962), Wedderburn (1964) and, more recently, by Coates (1973). From these reviews and from a study of the literature it became apparent that relatively little work had been done on interactions between preservatives and solid particles in aqueous suspension. Consequently, a range of preservatives not previously investigated in this respect was tested for loss of activity in the presence of fifteen powders commonly used in aqueous suspension in pharmaceutical and cosmetic formulations. In view of the information obtained in this preliminary study and after the development of more satisfactory analytical techniques it was decided to study in greater depth the interaction between these powders and selected organomercurials and quaternary ammonium compounds.
