  1. 1. Filtration System For On-Site Wastewater Treatment : Experiences From Modelling and Experimental Investigations

    Författare :Rajabu Hamisi; Gunno Renman; Anders Wörman; Scholz Miklas; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Land and Water Resources Engineering; Mark- och vattenteknik;

    Sammanfattning : Many on-site wastewater treatment systems in Sweden are not sustainable in terms of treatment efficiency, nutrient recycling and economics. Achieving reliable and sustainable systems to meet on-site wastewater treatment demands requires comprehensive field investigations of the performance of novel technologies. LÄS MER

  3. 2. Effects of Safety Measures for Pedestrians and Cyclists at Crossing Facilities on Arterial Roads

    Författare :Mohsen Towliat; Institutionen för teknik och samhälle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transport technology; arterial roads; interaction points; Keywords: traffic safety; pedestrian and cyclist safety; conflict study; behavioural study; experimental site; control site; physical measure; evaluation design; variable message sign; pedestrian and cycle crossing; speed measurement.; 30 50 road environment; Transportteknik; Road transport technology; Vägtransportteknik;

    Sammanfattning : The principal aims of this thesis are to define suitable measures for safer pedestrian and cycle crossings on arterial roads, to implement these measures on a large scale and to acquire an insight into their effects on road users' safety, experiences, mobility and the environment, by creating a 30 km/h milieu at the above crossings. Two characteristically different types of measures, physical measures and variable message signs, based on three principles, lower speed, no priority and improved and relevant information, are tested within the framework of this project.

  4. 3. Regeneration measures in time and space : Site preparation, planting and digital tools

    Författare :Per Nordin; Karin Hjelm; Erika Olofsson; Nelson Thiffault; Linnéuniversitetet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Betula pendula; microsite; Picea abies; Pinus contorta; Pinus sylvestris; planting; regeneration; site preparation; remote sensing; Betula pendula; mikromiljö; Picea abies; Pinus contorta; Pinus sylvestris; föryngring; plantering; markberedning; fjärranalys; Technology byts ev till Engineering ; Teknik;

    Sammanfattning : Regeneration success depends on decisions made based on factors on aregional, site, and microenvironmental level. Therefore, understanding andmapping of such factors between and within sites can guide decisions forbetter seedling establishment. LÄS MER

  7. 5. Studies on experimental anaerobic infections of the middle ear and on the polymorphonuclear leukocyte function under anaerobic conditions

    Författare :Magnus Thore; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Otitismedia; anaerobicbacteria; experimental; nitroimidazoles; antibody; phagocytosis; anaerobiosis;

    Sammanfattning : Despite the clinical importance of anaerobic bacteria in otitis media and the uncertainty regarding the proper treatment of the anaerobic focal infection, few experimental studies focused upon the role of these microorganisms in otitis media have been publis­hed. In the present investigation a guinea-pig model for the induc­tion of anaerobic monoinfections in the middle ear was described. LÄS MER
