41	A variabilidade espacial no sítio Osvaldo : estudo de um assentamento da Tradição Barrancóide na Amazônia Central / Spatial variability in the Osvaldo site : study of a settlement of the Barrancoid Tradition in Central Amazonia Ricardo Andres Chirinos Portocarrero 11 April 2007 (has links) O presente trabalho é uma tentativa de desenvolvimento de novas metodologias para o entendimento do uso do espaço interno em sítios arqueológicos de terra firme da Amazônia Central. Há décadas diversos investigadores vêm debatendo sobre a variabilidade destes assentamentos (Meggers, Lathrap, Myers, Roosevelt, Heckenberger e Neves, entre outros). Nosso caso de estudo é o sítio Osvaldo, localizado na área de interfúvio dos rios Negro e Solimões, na margem sul do Lago do Limão. Este sítio apresenta internamente áreas heterogêneas, com variabilidade de profundidade de terra preta antropogênica de densidade de fragmentos cerâmicos, estes afiliados culturalmente à Tradição Barrancóide/fase Manacapuru e à fase Paredão. A análise de agrupamento espacial e padrão composicional mostram similitudes e diferenças entre as áreas mencionadas, evidenciando uma complexidade social interna, cujo entendimento, a partir de analogias etnográficas, tem relevância não apenas para a problemática intra-sítio, mas também para a discussão sobre as relações entre sítios a nível regional e sobre os movimentos migratórios de populações pré-coloniais. / The present work is an attempt to develop new methodologies for the understanding of the use of the internal space in archeological hinterland (terra firme) sites in Central Amazon. For decades, several investigators have debated the variability of these settlements (Meggers, Latrhap, Myers, Roosevelt, Heckenberger and Neves, among others). Our case study is the Osvaldo site, located between Solimões and Negro rivers at the South margin of Limão lake. This site internally displays heterogeneous areas with different depths of anthropogenic terra preta and variable density of pottery fragments culturally linked to the Barrancoid Tradition / Manacapuru phase and Paredão phase. The spatial clustering analysis and the composítional pattern show similarities and differences among the mentioned areas, presenting internal social complexity, of which the observation, from ethnographical analogies, is relevant not only for the intra-site problematic but also for the discussion on the relations among sites at regional level and for understanding the migratory movements of pre-columbian populations.

42	Portable Analyzer for On-Site Determination of Dissolved Organic Carbon — Development and Field Testing Glorian, Heinrich, Schmalz, Viktor, Lochyński, Pawel, Fremdling, Paul, Börnick, Hilmar, Worch, Eckhard, Dittmar, Thomas 25 February 2019 (has links) Dissolved organic carbon (DOC) is a sum parameter that is frequently used in water analytics. Highly resolved and accurate DOC data are necessary, for instance, for water quality monitoring and for the evaluation of the efficiency of treatment processes. The conventional DOC determination methods consist of on-site sampling and subsequent analysis in a stationary device in a laboratory. However, especially in regions where no or only poorly equipped laboratories are available, this method bears the risk of getting erroneous results. For this reason, the objective of the present study was to set up a reliable and portable DOC analyzer for on-site analysis. The presented DOC system is equipped with an electrolysis-based decomposition cell with boron-doped diamond electrodes (BDD) that oxidizes the organic compounds to carbon dioxide. Within this study, the influence of different electrode materials and the composition of the applied electrolytes on the DOC decomposition in an undivided electrolytic cell were systematically investigated. Furthermore, some technical aspects of the portable prototype are discussed. After a detailed validation, the prototype was used in an ongoing monitoring program in Northern India. The limit of detection is 0.1 mg L−1 C with a relative standard deviation of 2.3% in a linear range up to 1000 mg L C−1. The key features of the portable DOC analyzer are: No need for ultra-pure gases, catalysts or burning technology, an analyzing time per sample below 5 min, and a reliable on-site DOC determination. info:eu-repo/classification/ddc/610 ddc:610
43	Using vernacular design to alleviate inequalities in socio-spatial access: A case study of Dubai’s park provision. Törnroth, Suzanna January 2017 (has links) This thesis focuses on park planning in Dubai, and how current differences in their socio-spatial access can be alleviated by using regional-vernacular design principles. The thesis uses a mixed method approach that begins with the analysis of parks across the entire city to understand their current access and distribution, and then narrows down to focusing on four micro-case studies,which will serve as sites where improvements could be made. These improvements are inspiredby vernacular design and planning and aim to improve current access.

44	Kwasizabantu : a spatial development framework and detail design Wentzel, Dorithea Maria 06 May 2009 (has links) The aim of this thesis is to analyse and interpret the existent and future needs of the people and environment of the mission station, Kwasizabantu,to ensure settlement growth that will enhance the social, economical and environmental aspects of the settlement. This will result in a development framework of the whole site, a master plan for the lifespan of the settlement and detailed design of the heart of the settlement. / Dissertation (ML(Prof))--University of Pretoria, 2009. / Architecture / unrestricted Greytown Spatial needs Community upliftment Spatial planning Poor infrastructure Environmental rehabilitation Expression of time Umvuti municipality Site analysis Kwasizabantu Mission station Technical drawings Road system hierarchy Placemaking Urban fabric Continuos movement system Settlement legibility Interconnectedness of functions Direct connections between functions Development zones Waste management Circulation analysis Drainage management Circulation planning Natural conservation management Ideal relationships for development Functional zones Remedial work Structuring actions Holding actions Growth directions Development framework Site plan Master plan Sketch plan Necessitous use Guild design Permaculture Access to the countryside The in-between Cultural context Open space system Multi-use of spaces Visual analysis Future development Self-supportive Hierarchy of spaces Stanger Traditional authority areas Short mist belt grasslands biome Jammerdaal farm Erlo stegen Tabitha school Settlement character Settlement character expression Development context Development boundaries Site planning Baseline information Design decision Economical context Environmental context UCTD
