Enhanced biological phosphorus removal (EBPR) was studied in laboratory scale experiments as well as in a full scale EBPR process. The studies were focused on carbon source transformations, the use of nitrate as an electron acceptor and characterisation of the microflora. A continuous anaerobic/aerobic laboratory system was operated on synthetic wastewater with acetate as sole carbon source. An ef

We consider a link serving multiple service classes. We evaluate the properties of the link admission control policies that are obtained from an efficient scheme proposed by Krishnan and Hubner (1997). The Krishnan and Hubner approach suggests efficient calculations of state-dependent routing criteria for multi-rate networks through state-space aggregation. Through simple examples we show that it

Service has traditionally been a forceful competitive tool in grocery retailing. Lately discount stores has proven to be a winning concept within North European grocery re-tailing and this has evoked a renewed interest in service quality and grocery retailing. The overall aim of this study is to enhance the understanding of customer perceived service quality within grocery retailing, by testing a

While once abstruse, 14-3-3 proteins are now well known as players in several cellular processes. These processes range from apoptosis and mitosis in mammals and yeast, to regulation of primary metabolism in plants. To date, 104 proteins have been shown to interact with 14-3-3s of which 85 are found in mammals and yeast, and 21 are found in plants. Their consensus action is to bind to phosphorylat

This paper presents the results of an explorative study on the strategies and tactics applied by the mechanical designer during the later phases of the design process. The method chosen for this study is experiment-based, which is appropriate for an in-depth examination of the designer's activities. Six experiments have been run based on three dimensions: 1) the carrying out of basic design tasks

Syftet med detta projekt var att studera samspelet mellan friktion, balansförmåga och halkrisker, samt att ta fram designrekommendationer för friktionskrav och halksäkrare skor och underlag. Sex studier har utförts innefattande friktionsmätningar av skor på olika underlag och temperaturer, studier av stående balans och gång på ramp med justerbar lutning samt fokusgruppintervjuer. Resultaten visar

Popular Abstract in Swedish Arkitekter har kritiserats för att ha en vag föreställning om begreppet kropp och hur det förhåller sig till den arkitektur de gestaltar. Om kropp alls medvetandegörs är det på ett allmänt och självidentifierande plan, alternativt genom de standardiserad mått som olika byggnormer föreskriver. Arkitekturens kroppsliga relationer och kroppens sensoriska meningsskapande ärBeginning with the notion that spatial and material qualities of architecture set limits and create conditions for how we make use of it, the overall aim and ambition of this thesis is to develop this notion and to contribute to a deeper understanding of the relationships that are produced between the materiality of architecture and a bodily appropriation of it. To investigate this the thesis esta
