  1. 1. Traffic Emissions of Aerosols

    Författare :Matthias Vogt; Douglas Nilsson; Eiko Nemitz; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Primary Aerosol Emissions; Carbon Dioxide Emissions; Traffic Aerosol; Urban Aerosol; Traffic Activity; Emission Factors; Eddy Covariance; Aerosol Flux; Atmosphere and hydrosphere sciences; Atmosfärs- och hydrosfärsvetenskap; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Non-exhaust traffic emissions are unregulated, yet the mass emission of non-exhaust particles may be larger than exhaust emissions. In addition, their emission factors (EF) are more uncertain than exhaust emissions. This thesis presents aerosol flux measurements in Stockholm using the eddy covariance method. LÄS MER

  3. 2. Catching the Bus in Old Age - Methodological Aspects of Accessibility Assessments in Public Transport

    Författare :Gunilla Carlsson; Hållbar vardag och hälsa i ett livsperspektiv; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Rehabilitering medicinsk och social ; revalidation; rehabilitation; kinesitherapy; cluster analysis; activity; functional limitation; crticial incident; Enabler; environment; elderly; focus group; model; occupational therapy; participant observation; planning; performance; travel; Physical medicine; Road transport technology; Vägtransportteknik;

    Sammanfattning : Engagement in daily activities is central for people’s health and well-being. Today, our activity arenas mostly cover great geographical areas, and to reach different activities we must travel. However, people with functional limitations are sometimes restricted in their travelling. LÄS MER

  4. 3. Muscle Responses in Dynamic Events. Volunteer experiments and numerical modelling for the advancement of human body models for vehicle safety assessment

    Författare :Jóna Marin Olafsdottir; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pre-crash dynamics; spatial tuning patterns; occupant kinematics; electromyography.; Traffic safety; muscle activity; human body models;

    Sammanfattning : Fatalities and injuries to car occupants in motor vehicle crashes continue to be aserious global socio-economic issue. Advanced safety systems that provide improvedoccupant protection and crash mitigation have the potential to reduce this burden. LÄS MER

  5. 4. Getting Work Done : The Significance of the Human in Complex Socio-Technical Systems

    Författare :Rebecca Cort; Anders A. Jansson; Jessica Lindblom; Ann Blandford; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; work; work practice; socio-technical system; workscape; workplace studies; ethnography; distributed cognition; activity theory; operational train traffic; manufacturing; human-computer interaction; HCI; safety-critical domain; Computer Science with specialization in Human-Computer Interaction; Datavetenskap med inriktning mot människa-datorinteraktion;

    Sammanfattning : This thesis aims to deepen the understanding of the role and relevance of the worker in the functioning of complex socio-technical systems. The perspective adopted is profoundly human-centred and the worker is considered as a resource. LÄS MER

  7. 5. The Protein Traffic on the Ribosome : The Mechanism and Regulation of Protein Synthesis in Prokaryotes

    Författare :Andrey Zavialov; Måns Ehrenber; Venki Ramakrishnan; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; yellow; ribosome; translation; Gagarin; nobel prize; Biokemi; Biochemistry; Biokemi;

    Sammanfattning : The aim of this work was to understand the molecular mechanism of translation and the mechanism of translation termination, in particular. Cleavage of peptidyl-tRNA and peptide release terminates translation of mRNA on the ribosome. In prokaryotes, three release factors (RFs) are involved in this process. LÄS MER
