  1. 1. Droplet Breakup in Automotive Spray Painting

    Author : Björn O Andersson; []
    Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; atomization; spray painting; computational fluid dynamics; breakup; surface tension;

    Abstract : Paint and surface treatment processes in a car paint shop are to a largeextent automated and performed by robots. Having access to tools thatincorporate the flexibility of robotic path planning with fast and efficientsimulation of the processes is important to reduce the time required forintroduction of new car models, reduce the environmental impact and increasethe quality.

  2. 2. Modeling and simulation of rotary bell spray atomizers in automotive paint shops

    Author : Björn O Andersson; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; spray painting; computational fluid dynamics; atomization; multiphase flow; breakup; coating; surface tension;

    Abstract : The paint and surface treatment processes in automotive paint shops are characterized by multiphase and free surface flows, multiphysics interactions, multiscale phenomena, and large moving geometries. The current version of the software for simulation of spray painting developed at the Fraunhofer-Chalmers Centre relies on measurements of droplet size distributions and velocity profiles below the applicator that can be used as input to the simulations.

  3. 3. Methods and Applications in Comparative Bacterial Genomics

    Author : Hans-Henrik Fuxelius; Siv Andersson; Björn Andersson; Uppsala universitet; []
    Keywords : Biology; Biologi;

    Abstract : Comparative studies of bacterial genomes, now counting in the hundreds, generate massive amounts of information. In order to support a systematic and efficient approach to genomic analyses, a database driven system with graphic visualization of genomic properties was developed - GenComp. READ MORE

  4. 4. Evaluation of Biomarker Responses in Fish : with Special Emphasis on Gill EROD Activity

    Author : Carin Andersson; Jan Örberg; Björn Brunström; Lars Förlin; Uppsala universitet; []
    Keywords : Biology; three-spined stickleback; biomarker; EROD; ethynylestradiol; gill; vitellogenin; spiggin; CYP1A inducers; humic substances; sperm quality; biomonitoring; Biologi;

    Abstract : Many chemicals present in the aquatic environment can interfere with physiological functions in fish. Exposure to chemicals can be revealed by the use of biomarkers. Induction of 7-ethoxyresorufin O-deethylase (EROD) activity is a commonly used biomarker for exposure to CYP1A inducers such as dioxins and polyaromatic hyrdrocarbons. READ MORE
