Teddy Vessels [also known as our former best friends]

Hansen, Felicia January 2022 (has links)
Teddy bears have become a universal symbol of our childhood, but we tend to forget them when we grow up. The toy industry is a growing empire where manufacturers constantly compete for consumers' attention. This results in growing waste from the toy industry and a need to find solutions to how to deal with it. This research explores repurposing possibilities of discarded stuffed animals based on their colour, form, texture, and print to create sculptural textile objects through deconstruction, patchwork, and sculpting techniques. This research was conducted by performing a series of design experiments exploring discarded stuffed animals through deconstruction and time-limited sketching. This allowed various sculptural objects to be constructed mainly by crazy pathworking and casting with different plaster materials or teddy bear filling. The outcome is a collection of 7 textile objects with a suggestive function, but the material it is constructed in challenges it. They extend from recognisable vase forms to forms that almost are unrecognisable. These objects place themselves in the field of not only textile design but also functional art. This research contributes to the field of textile design by suggesting a new usage for an atypical material, discarded stuffed animals. Furthermore, the collection Teddy Vessels [also known as our former best friends] proves that discarded stuffed animals still have a place in our lives even though we have forgotten them.

Hypervelocity impact analysis of International Space Station Whipple and Enhanced Stuffed Whipple Shields

Kalinski, Michael E. 12 1900 (has links)
Approved for public release; distribution in unlimited. / The International Space Station (ISS) must be able to withstand the hypervelocity impacts of micrometeoroids and orbital debris that strike its many surfaces. In order to design and implement shielding which will prevent hull penetration or other operational losses, NASA must first model the orbital debris and micrometeoroid environment. Based upon this environment, special multi-stage shields called Whipple and Enhanced Stuffed Whipple Shields are developed and implemented to protect ISS surfaces. Ballistic limit curves that establish shield failure criteria are determined via ground testing. These curves are functions of material strength, shield spacing, projectile size, shape and density, as well as a number of other variables. The combination of debris model and ballistic limit equations allows NASA to model risk to ISS using a hydro-code called BUMPER. This thesis modifies and refines existing ballistic limit equations for U.S. Laboratory Module shields to account for the effects of projectile (debris/ micro-meteoroid) densities. Using these refined ballistic limit equations this thesis also examines alternative shielding materials and configurations to optimize shield design for minimum mass and maximum stopping potential, proposing alternate shield designs for future NASA ground testing. A final goal of this thesis is to provide the Department of Defense a background in satellite shield theory and design in order to improve protection against micrometeoroid and orbital debris impacts on future spacebased national systems. / Lieutenant, United States Navy

[pt] Em decorrência do acirrado ambiente concorrencial, as empresas alimentícias de cárneos embutidos vêem-se obrigadas a melhorar seus sistemas produtivos de forma contínua, o que implica em definir de modo coordenado seu processo de busca e escolha de tecnologia dentro dos imperativos de higiene que devem vigorar nesse ramo industrial. Para que isso possa ser efetivamente implementado, faz-se necessário que a organização identifique as oportunidades mercadológicas reconhecendo, quando não os benefícios das novas tecnologias, ao menos a sua necessidade. Este trabalho apresenta a configuração da indústria de alimentos brasileira para então atingir o complexo carne, em especial o setor de cárneos embutidos. Em seguida, apresenta uma classificação da tecnologia e sua análise sob o ponto de vista estratégico. Adiante as formulações teóricas das etapas de absorção da tecnologia são avaliadas de acordo com a postura de empresas fornecedoras e compradoras de equipamentos do setor. Por fim, propõe uma estrutura de análise do funcionamento do processo de escolha de equipamentos, propiciando informações importantes à boa gestão das empresas e ao meio acadêmico. / [en] As a result of a strident competitive environment, food manufacturers of stuffed meat are required to improve their production processes continuouslly. The fact implies in defining, in a coordinated way, their procedures for technology search and selection, following higienic standards which must rule this industrial segment. For this purpose, food organizations need to identify market opportunities, recognizing the benefits of new technologies, or at least their usefulness. This study presents the actual configuration of the Brazilian food industry and sequentially the meat segment, more specifically the stuffed meat sector. It then discusses the concept of technology and overviews a methodology to technology strategic analysis. Moreover, the theorical formulations on the phases of technology use are evaluated in accordance with the attitude of equipment producers and their clients. Conclusivelly, it proposes an structured analysis of the process of equipment search, providing an important set of informations to a better industry management and also to academics. / [es] Debido a la alta competitividad, las empresas alimenticias de cárnicos embutidos se han visto obligadas a mejorar sus sistemas productivos de forma continua, lo que implica definir de modo coordinado el proceso de búsqueda y selección de tecnología dentro de las normas de higiene de esta rama industrial.

No. of bitstreams: 1 Dissertacao_Alessandra_Cesar.pdf: 697265 bytes, checksum: 10184ff73bda2eae43f740e932f05ea9 (MD5) Previous issue date: 2008-12-12 / Listeria monocytogenes is a gram-positive bacterium, anaerobic facultative, that grows under refrigerator temperature and it can cause listeriosis in human and animals. It is widely distributed in the environment and it has been isolated from food of animal and vegetal origin that was associated to outbreaks of high lethality in many coutries. Thus, this bacterium represents an important pathogen to the public health. Ready-to-eat products, like cooked stuffed food, within them, frankfurters are associated to human listeriosis in many countries. Taking into consideration the importance of the subject and the need of data about it, the occurrence of Listeria spp. and L. monocytogenes in industrial plants, in meat raw materials, in slurry and frankfurters was investigated. Theses samples were harvest in this two production plants with FIS; in one of them GMP, HACCP and SOP were implemented. The results of the microbiological analysis were submitted to the program @Risk to obtain the danger analysis; the mean values results showed that 7 to 9% of the frankfurters in the market may have L. monocytogenes. After serological typification, performed by Oswaldo Cruz Institute, 88 strains of L. monocytogenes were obtained from 106 samples; among them, 76 were harvest in the industrial plants that participate in the experiment, during a day shift production and 30 were harvest in the market. In serological typification, 95% of these strains were classified as serotypes 4b, 1/2a and 1/2b. Impressions about the behavior of the population that consumes frankfurters in the matters of storage proceedings and the pattern of consumption were obtained by the application of 500 questionnaires at random. The results of these questionnaires showed that the presence of the pathogenic serotypes of L. monocytogenes in meat raw materials, as well in frankfurters commercialized by heaps, and purchased like this by about 75% of the consumers interviewed, may represent a danger to the susceptible population, especially when considering the fact of 40% of the consumers said that they eat the frankfurters directly from the package, without cooking them. Besides the consumption practices, as unknown risk factors of the presence of L. monocytogenes found in frankfurters consumed in the country, we also have lack of epidemiological data, absence of patterns as well the deficient information given to the consumer associated to the incipient relation between federal regulatory agencies and the people / Listeria monocytogenes é uma bactéria Gram-positiva, anaeróbia facultativa, que se multiplica sob temperatura de refrigeração e pode causar listeriose em humanos e outros animais. Amplamente distribuída no ambiente, tem sido isolada de alimentos de origem animal e vegetal associados a surtos de elevada letalidade em diversos países, representando, portanto um patógeno importante para a saúde pública. Produtos prontos para consumo, como embutidos cozidos, entre os quais as salsichas, estão associadas à listeriose humana em alguns países. Considerando a relevância do tema e a necessidade de dados, analisou-se a ocorrência de Listeria spp. e L. monocytogenes no ambiente industrial, nas matérias-primas cárneas, emulsões e em salsichas produzidas nesses dois estabelecimentos com SIF, sendo que em um deles as ferramentas de autocontrole estavam implantadas. Os resultados das análises microbiológicas submetidos a análise de perigos, utilizando o programa @Risk, apresenta valores médios de que 7 a 9% das salsichas destinadas ao consumo possam conter L. monocytogenes. Na sorotipificação, realizada no Instituto Oswaldo Cruz, obteve-se 88 isolados de L. monocytogenes a partir de 106 amostras, sendo 76 colhidas durante um turno de produção diurno nas indústrias que participaram do experimento e 30 no varejo, sendo 95% dos sorotipos patogênicos 4b, 1/2a e 1/2b. Noções acerca do comportamento da população consumidora de salsichas quanto aos procedimentos de estocagem e as formas de consumo praticadas foram obtidas por meio da aplicação de 500 questionários de forma aleatória, demonstrando que a presença de sorotipos patogênicos de L. monocytogenes nas matérias-primas cárneas, bem como em salsichas comercializadas a granel, adquiridas nessa apresentação por cerca de 75% dos entrevistados, oferece riscos à população susceptível, especialmente relacionando-se aos fatos de que cerca de 40% dos consumidores admitem consumir salsichas diretamente da embalagem, sem antes submetê-las ao calor. Além das práticas de consumo, como fatores do risco desconhecido da presença de L. monocytogenes em salsichas consumidas no país, ressalta-se a escassez de dados epidemiológicos, a ausência de padrãos, bem como a falta de informação ao consumidor, associada a relação incipiente entre órgãos regulamentadores e cidadãos
