  1. 1. Particle concentrations : analysis methods for urban runoff

    Författare :Kerstin Nordqvist; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Sammanfattning : Urban runoff often contains high concentrations of particles. Pollutants that adsorbs to surfaces of particulate material will be transported to receiving waters or a sewage treatment plant. For the recipient, the particles in the runoff are a significant cause of water quality impairment. LÄS MER

  2. 2. Cell and Particle Trapping in Microfluidic Systems Using Ultrasonic Standing Waves

    Författare :Mikael Evander; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; acoustic particle manipulation; standing waves; trapping; ultrasound; cell handling; particle handling; Microsystem technology; lab on a chip; microfluidics;

    Sammanfattning : Analysis methods are currently being miniaturized in order to save time and money while achieving higher sensitivities. The ultimate goal is to create a lab-on-a-chip where all analysis steps and instruments can be automated and integrated into a single chip. LÄS MER

  3. 3. Acoustic Standing Wave Manipulation of Particles and Cells in Microfluidic Chips

    Författare :Andreas Lenshof; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; acoustic particle manipulation; separation; ultrasound; cell handling; particle handling; lab on a chip; Microsystem technology; microfluidics; standing waves;

    Sammanfattning : The rise of MEMS and µTAS techniques has created a whole new family of microfluidic devices for a wide range of chemical and biomedical analyses to be performed on small Lab-on-a-chip platforms. The operations often include small samples of particle or cell suspensions on which separation, mixing, trapping or sorting is performed. LÄS MER

  4. 4. Longitudinal Force Distribution and Road Vehicle Handling

    Författare :Matthijs Klomp; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ehicle dynamics; quasi steady-state; drive force; combined grip; longitudinal force distribution; combined slip; vehicle handling; optimization;

    Sammanfattning : The distribution of longitudinal forces has a large influence on vehicle handling characteristics such as the driver/vehicle interaction, road holding and yaw stability, in particular during combined traction/braking and cornering near the grip limit of the tires. In order to select and develop suitable driveline systems and associated active control that provide consistent driver/vehicle handling, maximum road holding and sufficient yaw stability margins, it is essential to understand the influence of a particular drive force distribution on these handling characteristics.

  5. 5. Health-related aerosol particle studies, respiratory tract deposition and indoor source identification

    Författare :Jakob Löndahl; Kärnfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aerosol particle; health; ultrafine particles; nanoparticle; deposition; respiratory tract; Fysicumarkivet A:000;

    Sammanfattning : Aerosol particles have, since Classical Antiquity, been linked to adverse effects on human health. It is estimated that the particles in urban air pollution causes 100 000 deaths in Europe each year, whereof 5 000 in Sweden. LÄS MER
