Nynäshamn´s City hall / Nynäshamns stadshall

Wahlgren, Felix January 2019 (has links)
Nynäshamn is a city with a rich industrial history, its municipal arms consist of partly an achor, and partly three gears. The identity of the city has been greatly impacted by the industry which today consist mainly of the harbour and the oil refinery. I strive in my project to bring together the forms of industrial Nynäshamn with the urban fabric of the inhabited parts of the city. A city is the sum of its parts although these parts tend to be conflicting within many cities causing the city to become an alien to its inhabitants. The city hall in my proposal is an attempt to overbridge the conflicts within the city´s narrative and a place for its inhabitants to meet. / Ett kommunvapen berättar om en stad präglad av 1900-talets industri, ett ankare symboliserar sjöfarten och tre kugghjul den industri som kommit att definiera stadens identitet. Idag utgör stadens oljeraffinaderi en tredjedel av den bebyggda ytan i Nynäshamn och det är det första som fångar ens blick om en skulle komma sjövägen.  Oljecisternernas cylindriska form har en viktig plats i  den växande staden och utgör en särpräglad typologi  likt San Gimignanos torn eller Hollands väderkvarnar. Det är sannolikt att vi i framtiden gått vidare till andra energikällor, oljecisternerna kommer då finnas kvar för oss att finna nya funktioner till. I mitt förslag är den cylindriska formen invävd i projektet för att bekräfta en typologi som både är närvarande och frånvarande i staden Nynäshamn

A região possui características naturais singulares no Brasil, tendo em boa parte de seu território a ocorrência do clima Semiárido. Estudos indicam que o fenômeno das secas remonta há milhares de anos, antes mesmo da ocupação humana no Nordeste brasileiro, porém a curta estação chuvosa presente hoje pode desaparecer, dificultando a prática da agricultura na região sem o uso de irrigação, sendo necessário que a região adote um novo perfil produtivo, inovando nas práticas de convivência com a seca. É imprescindível criar alternativas que contribuam para o desenvolvimento sustentável, principalmente para um gerenciamento mais adequado das águas nesta região. Com a finalidade de dialogar com essa realidade, foi desenvolvida a cisterna calçadão de 52 mil litros. Este trabalho objetivou-se em avaliar esta tecnologia como capaz ou não de contribuir com a produção de alimentos por agricultores familiares residentes no Semiárido pernambucano. O universo do estudo foi constituído por 4 agricultores beneficiados por Cisternas Calçadão e que já utilizam a tecnologia há mais de um ano, residentes nos municípios de Cumaru e São Caetano /PE. O trabalho de campo foi dividido em duas etapas, Etapa Qualitativa ou de Gestão (que consiste em avaliar a eficácia da cisterna calçadão como tecnologia ambiental utilizada na produção de alimentos no Semiárido pernambucano), iniciado a partir da aplicação de um questionário por agricultor, para posterior construção do Discurso do Sujeito Coletivo (DSC) e Etapa Quantitativa ou da Qualidade da Água (que consiste em avaliar a qualidade físico-química da água e sua quantidade utilizada para produção de alimentos). Foram realizadas 3 campanhas de análise físico-química das águas contidas nas cisternas, mensuração do nível diário de água na cisterna, e registro do índice pluviométrico local. Os resultados encontrados demonstram que a demanda por água, para fins produtivos, em 50% das famílias, ultrapassa a capacidade de acúmulo da cisterna calçadão que é de 52 mil litros. Para manutenção da produção de alimentos e/ou dessedentação dos animais é necessário cerca de 3.064 litros/mês, contudo, apenas 50% da água da cisterna é usada para fins produtivos. No que diz respeito ao coeficiente de escoamento superficial (C) da área de captação, identificou-se que eventos pluviométricos ocorridos em dias consecutivos são os maiores fatores de influência para esse índice, ao passo que o valor médio de C = 0,50, indica que o calçadão tem uma eficiência de apenas 50% em captar a chuva. Em relação à qualidade da água, conclui-se que todas se encontram fora dos padrões de potabilidade apresentando teores elevados tanto de coliformes totais quanto de E.coli. Por fim, conclui-se que os agricultores revelaram ter conhecimento sobre o manejo da água da cisterna calçadão, contudo necessitam de uma melhor compreensão da técnica para serem capazes de promover uma gestão mais próxima à situação de conservação da água. / In Brazilian scene, Northeast Region is the one that has the majority rural residents, in proportion to the total population: 26,87% of the total population live in the municipalities’ rural areas. The region possess unique natural characteristics in Brazil, where semi-arid climate covers most parts of its territory. Although studies have indicate that the phenomenon of drought traces back thousands of years, even before man settlements in Brazilian Northeast, the current short rainy season may disappear, therefore making it impossible to cultivate agriculture over the region without the use of irrigation, or either access to water may be very difficult. It will be required an adoption of a new productive profile, innovating the practice of living with drought, empowering small productive areas, diversifying their crop production. It is extremely necessary to create alternatives that contribute to sustainable development, principally for a more satisfactory water management in this region. A 52 thousand liter calçadão cistern was designed with the purpose to deal with actual conditions. This research aims to evaluate whether this technology is capable or not to contribute to production of food by local family farmers in semi-arid in Pernambuco State. The total study population is consisted of 4 farmers, who have been benefited by calçadão cisterns and already have used the technology for more than a year, and are residents in the municipalities of Cumaru and are Caetano / PE. The fieldwork was divided into two phases, qualitative or management phase (analyzing the efficacy of calçadão cistern as an environmental technology used in food production in semi-arid of Pernambuco), which started from the application of a questionnaire per farmer for posterior elaboration of (collective subject speech) CSS, as well as quantitative phase or water quality phase, (analyzing physical-chemical water quality and quantity used for food production). It was carried out 3 physical-chemical analysis surveys of water reserved in the cisterns, measurements of the daily level of water in cistern and records of local rainfall indexes. The results showed that the demand for water for productive purposes, for water in 50% of the families, exceeds the accumulation capacity of the calçadão cistern, which is 52,000 liters. To maintain food production and or animals watering is necessary 3.064, liters/month, but only 50% of water in cistern is used for productive purposes. Regarding to the runoff coefficient (C) of the capture area, it was identified that precipitation events occurred on consecutive days are major influence factors to this rate, whereas the average value of C equals to 0.50, meaning that the calçadão has an efficiency of just 50% in capturing rain. With respect to water quality, it is concluded that they all fall outside consumption standards, obtaining high levels of both total coliforms as E.coli. Finally, it is clear that even though farmers were found to have knowledge of the used technology, they need a better understanding of the technique in order to be able to promote a closer management to conserve water situation.

Impacto de intervenções nutricionais no valor da pegada hídrica do produto leite bovino / Impact of nutritional management on the dairy milk water footprint

Novelli, Táisla Inara 29 November 2017 (has links)
O objetivo do trabalho foi avaliar o impacto de intervenções nutricionais no valor da pegada hídrica do produto leite bovino. O cálculo da pegada hídrica considerou as águas verde, azul e cinza, consumidas no sistema de produção e no beneficiamento do produto. Para determinação dos consumos de água no sistema de produção foram selecionados dois grupos experimentais, cada um contendo sete vacas em lactação. As dietas fornecidas a cada grupo continha os mesmos ingredientes. Porém, na composição do concentrado havia diferentes percentuais proteicos. O concentrado fornecido ao Grupo 1, continha 20% de proteína bruta, e o concentrado fornecido ao Grupo 2, tinha seu teor de proteico ajustado de acordo com a produção de leite do grupo, ao longo da lactação. O ajuste do teor de proteína da dieta as necessidades dos animais promoveu a redução dos consumos das águas verde, azul e cinza e da pegada hídrica do produto leite. A pegada hídrica do Grupo 1 com base no nitrato foi de 503,79 L kg-1 de FPCM (86,1% água verde, 13,4% água azul e 0,43% água cinza) e a do Grupo 2 foi de 452,59 L kg-1 de FPCM (85,3% água verde, 14,3% água azul e 0,45% água cinza). Com base no fósforo, a pegada total do Grupo 1 foi igual a 518,43 L kg-1 de FPCM (83,7% água verde, 13,1% água azul e 3,2% água cinza) e a do Grupo 2 foi de 465,16 L kg-1 de FPCM (83% água verde, 13,9 % água azul e 3,1% água cinza). Entre as três águas, a verde foi a que apresentou maior consumo, atestando a importância da eficiência hídrica na agricultura para os produtos de origem animal. A prática de irrigação das pastagens representou o maior consumo de água azul. O Grupo 2 apresentou melhor eficiência de uso de nutrientes, mas em ambos os grupos as entradas foram maiores que as saídas. O balanço do Grupo 1 foi de 962,7 kg de N, 95,2 kg de P e 545,1 kg de K e do Grupo 2, 869,4 kg de N, 57,8 kg de P, 601,9 kg de K. A captação de água de chuva por cisterna foi avaliada como uma tecnologia hídrica. Essa demonstrou ter impacto positivo na redução do volume de água captado de fonte natural, mas a análise financeira da tecnologia se mostrou inviável para a condição produtiva do estudo. A utilização de intervenções nutricionais que promovam o melhor aproveitamento dos nutrientes pelos animais demonstrou ser uma prática que também contribui para melhoria da eficiência hídrica do sistema de produção e dos produtos de origem animal. Estudos que relacionam o cálculo da pegada hídrica com os aspectos produtivos da pecuária promoverão impactos positivos na conservação dos recursos hídricos e no desempenho dos sistemas de produção. / The aim of the study was to evaluate the impact of nutritional interventions on the dairy milk water footprint. Water footprint calculation considered the green, blue and gray water consumed in the production system and in the dairy unit. To determine the water consumption in the production system was selected two experimental groups with seven lactating cows each. The diets provided to each group contained the same feeds. However, concentrate had different crude protein contents. The concentrate feed Group 1 contained 20% of crude protein, and the concentrate feed Group 2 had its protein content adjusted according to the milk production of the group. The adjustment of the protein content promoted a lower consumption of green, blue and gray water and the reduction of water footprint value. The water footprint based on nitrate in the Group 1 was 503.79 L kg-1 of FPCM (86.1% green water, 13.4% blue water, and 0.43% gray water) and in the Group 2 was 452.59 L kg-1 FPCM (85.3% green water, 14.3% blue water, and 0.45% gray water). Water footprint based on phosphorus was 518.43 L kg-1 of FPCM to Group 1 (83.7% green water, 13.1% blue water, and 3.2% gray water) and to Group 2 was 465.16 L kg-1 of FPCM (83% green water, 13.9% blue water, and 3.1% gray water). Green was the highest volume consumed. This shows the relation between agriculture water efficiency and the water footprint of animal products. Irrigation represented the highest consumption of blue water. The nutrient use efficiency was better to Group 2, but in both groups the inputs were higher than the outputs. The nutrient balance for Group 1 was 962.7 kg N, 95.2 kg P and 545.1 kg K and for Group 2, 869.4 kg N, 57.8 kg P, 601.9 kg of K. Rainwater harvesting in a cistern was evaluated as a water technology. It had a positive impact on reducing the withdraw from ground source, but the economic analysis of the cistern was unfeasible for the productive condition. The use of nutritional interventions for lactating cows promoted better nutrient utilization and has proved to be a management that contributes to the increase of water efficiency in the production system and to animal products. Studies that relate the water footprint with productive aspects of livestock will promote positive impacts on the water conservation and on the performance of production systems.

An Archaeological Study of Architectural Form and Function at Indian Key, Florida

Driscoll, Kelly A 31 October 2003 (has links)
Indian Key Historic State Park is a small island located on the Atlantic Ocean side of the Florida Keys, near Islamorada. Before it was bought by the state of Florida in 1970, Indian Key had been the setting for a number of historically significant activities. The most well known of these is the 1840 raid on the people and buildings that made up a small wrecking village, established on the island by Jacob Housman in the early 1830s. The limestone foundations of these structures are the main attraction to today's visitor to the park. There is more to the story of Indian Key, though, than the Housman period and the structural remains left behind from this stage of the island's history. Almost immediately after the near destruction of the island in 1840, the Florida Squadron of the Navy took over, constructing their own buildings, and re-using some of the previously constructed foundations. This cycle of rebuilding and re-use continued for another hundred years, with families and fishers trying to inhabit and profit from Indian Key. The focus of this thesis is to examine the foundations and associated archaeological features of Indian Key in order to determine better periods of use and re-use for the buildings that have been identified through archaeological investigations. This research was conducted in order to examine the site's architecture through an archaeological perspective; it is by no means an attempt at a complete architectural study of the site. Rather, it is an effort to examine the entire island of Indian Key, by focusing on the history of the buildings that helped make it an important piece of Florida's past.

Život v pozdní antice: kontextuální analýza keramiky ze severního svahu Vesuvu / Life in Late Antiquity: A Contextual Analysis of the Pottery from the North Slope of Vesuvius.

Benková, Martina January 2018 (has links)
The present thesis examines two ceramic assemblages from the villa baths at Pollena Trocchia, Italy. The private bath complex was likely part of the Roman villa built at the beginning of the 2nd century AD and buried under the volcanoclastic debris of the AD 472 eruption which provided an important terminus ante quem. The previous studies demonstrated that in the 5th century AD the bath complex became a pottery dump and cemetery. Nevertheless, a different picture was drawn from the excavation of the underground cistern in the north-western part of the baths. In order to better understand the purpose of the cistern prior to the eruption, which sealed most of the site, the pottery assemblage from the cistern was compared to the assemblage from one of the bathrooms identified as the laconicum. In fact, the cistern uncovered rather low number of individuals compared to the rest of the baths and the ratio of attested pottery classes was limited. While the African imports were almost absent, there was a great number of local products. Most of the shapes consisted of locally produced jugs of big volume, which could be associated with the water-supply system. When possible, the individuals were dated to the second half of the 5th century. Therefore, it is likely that the cistern was still in use a long...

To this end, we discuss as the issue of water has remained in the development agenda of the semiarid and how the P1MC has been presented as an alternative to the democratization of water in the region. We investigated the deployment process P1MC in three municipalities in the semiarid paraibano: Patos, São José de Espinharas e Malta. The three municipalities are located within range of the Patos Diocesan Social Action (ASCP) that acts locally as a Manages Unit Microregional (UGM) of the P1MC (PB-03). Were interviewed Twenty families with the objective to apprehend in what way the beneficiaries participate in the program at the local level and how families perceive the participatory process. It was found that participation was reduced to a formal character, procedural, the extent that the participatory process did not occur as a result of a work-sharing ideas and goals, but as an obligation to be fulfilled for acquiring the cistern. Featuring thus a participation subordinated, with protocolar character. It was also noted that the cisterns have not been sufficient to meet the needs of part of the families interviewed, while the distribution of water by tanker car remains a common practice in the daily life of the communities studied. However, the cistern has decreased the dependence of families and promoted a relative autonomy of water. / O presente trabalho busca discutir a natureza da participação social no Programa de Formação e Mobilização para Convivência com o Semiárido - Programa Um Milhão de Cisternas (P1MC). Para tal, discute-se como a questão da água tem permanecido na agenda de desenvolvimento do semiárido e de que forma o P1MC vem sendo apresentado como uma alternativa de democratização da água na região. Foi investigado o processo de implantação do P1MC em três municípios do semiárido paraibano: Patos, São José de Espinharas e Malta. Os três municípios estão localizados no raio de ação da Ação Social Diocesana de Patos (ASCP) que atua na região como uma Unidade Gestora Microrregional (UGM) do P1MC (PB-03). Foram entrevistadas vinte famílias com o objetivo de apreender de que forma os beneficiários participam do programa no nível local e como as famílias percebem o processo participativo. Verificou-se que a participação esteve reduzida a um caráter formal, procedimental, na medida em que o processo não se deu como reflexo de um trabalho de compartilhamento de ideias e objetivos, mas como uma obrigação a ser cumprida para se adquirir a cisterna. Caracterizando, assim, uma participação subalternizada, de caráter protocolar. Notou-se também que as cisternas não têm sido suficientes para suprir as necessidades de parte das famílias entrevistadas, ao passo que a distribuição de água por carro-pipa continua sendo uma prática comum no cotidiano de parte das comunidades estudadas. Contudo, a cisterna tem diminuído a dependência das famílias e promovido uma autonomia hídrica relativa.
