Donovan-Boyd, Adrienne K. 06 1900 (has links)
xiii, 207 p. : ill. (some col.), maps. A print copy of this thesis is available through the UO Libraries. Search the library catalog for the location and call number. / Preserving Pacific Northwest historic beach houses in coastal communities can often be a daunting task due to the complexities that arise when combining preservation, planning, development, and climatic hardships. Using Tillamook County's coastline as the study area, this thesis explores the historical development of Tillamook County's structures and the current barriers that exist when trying to preserve them. Historical discussions include the development of transportation routes, recreational amenities, and the evolution of coastal construction materials, along with historic local and regional planning decisions that helped shaped towns along Tillamook County's coastline. Following this historical discussion, current preservation challenges will be discussed as well as the recommendations for preserving and maintaining vernacular coastal beach houses of the Pacific Northwest. / Committee in Charge: Leland Roth, Chair; Donald Peting

Avaliação do potencial invasivo de espécies não-nativas utilizadas em plantio de restauração de matas ciliares /

Assis, Geissianny Bessão de, 1986- January 2012 (has links)
Orientador: Giselta Durigan / Coorientador: Vera Lex Engel / Banca: Marco Antonio de Assis / Banca: Fláviana Maluf de Souza / Resumo: A restauração de ecossistemas vem ganhando espaço em todo o mundo e, no Brasil, o modelo mais amplamente utilizado tem sido o plantio de espécies arbóreas em alta diversidade. Embora a recomendação seja de que se utilizem exclusivamente espécies nativas, a dificuldade de identificá-las e de se encontrarem mudas disponíveis resulta que em muitos plantios existem espécies não-nativas, as quais oferecem a ameaça potencial de invasão biológica. O objetivo desta pesquisa foi analisar o potencial invasivo das espécies arbóreas não-nativas que têm sido plantadas para a restauração de matas ciliares em região de Floresta Estacional Semidecidual - FES, com base na estrutura de suas populações e em sua contribuição para as comunidades em restauração. Selecionamos 25 plantios de matas ciliares situados na bacia do rio Paraná, com idades variando entre quatro e 53 anos. Em cada local efetuamos o levantamento da comunidade arbustivo-arbórea em área total de 1.000 m2, dividida em 10 parcelas de 100 m2, aleatoriamente distribuídas dentro da faixa de 0 a 50 m de distância da margem do corpo d‟água. Identificamos e contabilizamos todos os indivíduos de espécies arbóreas e arbustivas, plantadas ou regenerantes, a partir de 50 cm de altura, agrupando-os em três classes de tamanho segundo o diâmetro à altura do peito (DAP < 1 cm, 1 cm < DAP < 5 cm e DAP > 5 cm). Classificamos os indivíduos em plantados ou regenerantes com base no alinhamento do plantio, evidente mesmo em plantios mais antigos. No total, amostramos 18.421 indivíduos, pertencentes a 320 espécies, das quais 83 (26%) não eram nativas da região estudada. Com relação à origem das espécies amostradas nos plantios, 65% são nativas de FES, 19% são nativas de outras formações vegetacionais brasileiras e 16% são...

The most widely used model in Brazil has been the planting of the high diversity tree species. Although the recommendation it is planting only native species during restoration, the difficulty to identify them and to find seedlings available, result in many planting are found non-native species, which offer the potential threat of biological invasion. The purpose of this study was to analyze the potential of invasive non-native tree species that have been planted to riparian forests restoration in the region of semideciduous forest, based on the structure of their populations in regeneration. We selected 25 areas in restoration, of the aged between 4 and 53 years after planting. At each site we carried out the floristic inventory in the total area of 1.000 m2, divided into ten plots randomly distributed, within the range of 0 to 50 m away from the edge of the water body. Identify and account for individuals of all tree and shrub species present in the understory, from 50 cm tall, grouped into three size classes by diameter at breast height (DBH < 1 cm, 1 cm < DBH < 5 cm and DBH > 5 cm) . We classify the species planted and regenerating based on the alignment of planting, evident even in the oldest plantation. In total, 18.421 individuals sampled, belonging to 320 species. Regarding the origin of the species in plantations, 65% are native FES, 19% are of other native vegetation formations in Brazil and 16% are from other countries. Only three areas were not planted non-native species. In other areas, non-native species were used in varying proportions, to a maximum of 54% of all species sampled from planted trees in a community restoration. The proportion of individuals of non-native species from regenerating plants (12%) was lower than XIV the proportion... (Complete abstract click electronic access below) / Mestre

The impact of contemporary exhibitions in historical buildings: Retaining significance and authenticity during adaptation

Slabbert, Barend Petrus January 2015 (has links)
Thesis (MTech (Design))--Cape Peninsula University of Technology, 2016. / Historical interiors hold within them significance which provides us with cultural identity, as well as historical and aesthetic value, and their physical materials offer us a connection to the past. These interiors and their functions often become obsolete and need to acquire a new function that is more suited to our modern-day society. One such change in function which was identified to be steadily on the rise in Cape Town is the reappropriation of historical interiors into contemporary exhibition venues. It was noted that during this process many of these historical interiors end up as neutral contemporary white boxes, where the whole historical interior is replaced or concealed by a pristine white interior and this leads to a loss of its internal historical aesthetic value. To counter this and to retain the significant aesthetics of these interiors for ourselves and our future generations, heritage legislation offers a certain amount of protection through their respective guidelines and principles during adaptation. However, these guidelines do not offer concrete methods on the responsive adaptation of historical interiors into contemporary exhibition spaces. To address this problem and provide a substitute for the white box, alternative methods for the responsive adaptation of the historical interior into a contemporary exhibition space are highlighted and investigated. Through this investigation, this study aims to provide responsive approaches which interior designers may adopt during adaptation that respect, acknowledge and highlight the significance of the reappropriated space in the design of contemporary exhibition venues.

Taipa, canela preta e concreto: um estudo sobre a restauração de casas bandeiristas em São Paulo / Taipa, blackleg and concrete: A study on the restoration of the bandeirantes houses in Sao Paulo

Lia Mayumi 21 March 2006 (has links)
Partindo do pressuposto da existência de um paradigma constituído pelo modelo pioneiro de restauração de casas bandeiristas estabelecido pelo IPHAN desde os anos iniciais de sua atividade em São Paulo, o presente trabalho pretende realizar uma análise, em relação àquele paradigma, dos projetos e obras de restauração de cinco casas bandeiristas pertencentes à Prefeitura de São Paulo. Adotando a hipótese da sucessão cronológica de três momentos de continuidade, de diluição e de abandono do paradigma , o presente trabalho busca verificá-la através da análise dos projetos e das obras de restauração realizadas nos exemplares selecionados. Esses projetos e obras foram orientados inicialmente pelo IPHAN Instituto do Patrimônio Histórico e Artístico Nacional e depois, pelo DPH Departamento do Patrimônio Histórico da Prefeitura de São Paulo no período compreendido entre as décadas de 1950 e 2000. / This work analyses the architectural restoration of five bandeirantes houses in the city of São Paulo. Those restoration works, which took place between the years 1950 and 2000, were accomplished by the IPHAN Institute for National Artistic and Historical Heritage and the DPH Historical Heritage Department of the City Government of São Paulo. The work aims to identify and characterize both the conceptual and technical models that guided those restoration works. Assuming that IPHAN has developed a conceptual and technical paradigm in the restoration of this architectonical type, the work investigates the paradigms permanence extent in those five houses and, reversely, its vanishing along the almost fifty years comprising this study.

Post-Injury Recovery, Reattachment, Survival and Growth of the Giant Barrel Sponge, Xestospongia muta, Offshore Southeast Florida

Bush, Stephanie J. 01 July 2012 (has links)
The giant barrel sponge, Xestospongia muta is a prominent component in southeast Florida reef communities and is often injured from anthropogenic or natural disturbances. The resulting complete or partial shearing of X. muta barrels frequently leads to mortality of loose fragments that do not typically reattach. This study examines the degree to which sponge size and injury severity affects recovery and growth, and explores artificial reattachment success and growth of fragments. In June 2008, 65 sponges were subjected to injury treatments of approximately 50% or 90% barrel removal. A new, simple method was developed to secure these removed barrels (fragments) to the substrate. For 15 months, all donor, fragment and control sponges were monitored for survival, recovery and growth (change in height), and fragments were additionally monitored for reattachment. All injured sponges showed signs of recovery within 1 month. Within 7 months the reattachment method had already proved successful with more than 80% of all fragments becoming attached; final reattachment success after 15 months was 87%. Survival remained high for donors (97%), fragments (94%) and controls (97%). Size class and injury treatment did not significantly affect survival for donors. However, larger fragments had significantly lower survival and reduced reattachment success. Fragment growth rates were significantly lower than donor and control sponges. All sponges showed significant increase in height from post-cutting to the final monitoring. No injured donors reached pre-cut heights, however those from the smaller size class are projected to reach pre-injury heights faster than the larger size class.

Transformation of the artifact : adaptive reuse of the LaSalle Coke Tower in Montreal, Quebec

Weryk, Michael E. 05 1900 (has links)
The LaSalle Coke Tower is an existing structure located on a fifty-five foot strip of land bordering the south edge of the Lachine Canal and the north side of St. Patrick's St. (Montreal, Quebec). The railway passes through the structure at its base. Built at the turn of the century, the crane was used to hoist coal from barges to an elevated conveyor that carried it across the street to Cote-St.-Paul Gas Works. It is approximately 15 storeys high (167'). The Lachine Canal serviced the cause of industry from its completion in 1824 to the opening of the St. Lawrence Seaway in 1959 at which time industry slowly began to abandon the Lachine Canal area. The basic premise of the design project revolved around both preservation and development of Tour LaSalle Coke (LaSalle Coke Tower). Regarding preservation, it was the state of abandonment that was to be preserved, allowing for a sense of mobility, vagrant roving, free time, and liberty. Architectural production within the abandoned site must respond to the rhythms and flows of the passing of time and the loss of limits. The two principal components include a provision for discovery (architecture as a heuristic device) and an archive component housing historical documents relevant to the tower and it's surrounding context (the Lachine Canal). The essence of the project was to develop this type of site without destroying its character and without detracting from its historical significance. Careful consideration was essential to negotiate between development and preservation. A broader interpretation of heritage preservation was necessary: moving beyond the isolated monument to include territory which characterizes a particular place. In this instance tire place consisted of the extreme linear space of the canal and its adjacent properties in addition to the remnant architectural artifact of the tower. The state of abandonment is a part of the history of the site. The provision for discovery is made through the use of stairs and an elevator, allowing visitors uninhibited access to the tower. This provision allows for multiple levels of interaction with the artifact, from the short visit to a more comprehensive survey of the object. The archive component is a smallscale intervention thereby minimizing the impact of specialized components (or private spaces) which limit the sense of mobility, vagrant roving, free time and liberty. For the same reason, the food service and primary toilet facility is located 'off site' approximately 320 feet to the east. The goal was to retain the basic features of the artifact while providing for a means of discovery and documentation of a National Historic Landmark. / Applied Science, Faculty of / Architecture and Landscape Architecture (SALA), School of / Graduate
