  1. 1. Suspended solids and metals in highway runoff : implications for treatment systems

    Författare :Magnus Hallberg; Gunno Renman; Thomas Pettersson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental engineering; Miljöteknik;

    Sammanfattning : It is known that traffic is a source of pollutants and that pollutant loads increase with elevated traffic densities. Studies executed in Stockholm, Sweden advocate that highway runoff from roads with an annual average daily traffic (AADT) exceeding 30,000 vehicles need treatment before discharge to the receiving water.

  3. 2. Studies of Functional Interactions within Yeast Mediator and a Proposed Novel Mechanism for Regulation of Gene Expression

    Författare :Magnus Hallberg; Stefan Björklund; Karl Ekwall; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Mediator; Transcriptional regulation; Srb10; Cdk8; Med2; Srb7; Med21; RNA pol II; Biokemi; Biochemistry; Biokemi; medicinsk biokemi; Medical Biochemistry;

    Sammanfattning : The yeast Mediator complex is required for transcriptional regulation both in vivo and in vitro and the identification of similar complexes from metazoans indicates that its function is conserved through evolution. Mediator subunit composition and structure is well characterized both by biochemical, genetic and biophysical methods. LÄS MER

  4. 3. Treatment conditions for the removal of contaminants from road runoff

    Författare :Magnus Hallberg; Gunno Renman; Jiri Marsalek; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dissolved matter; filter bed; particulate matter; sedimentation; suspended solids; Environmental engineering; Miljöteknik;

    Sammanfattning : The pollutant load in road runoff is related to traffic densities and road maintenance activities. Inurbanised areas treatment of road runoff is common and often considered necessary. The pollutantsare partitioned between the particulate and dissolved matter. However, the contaminantstend to have an affinity to the particulate material. LÄS MER

  5. 4. Signal Transduction in Mast Cell Migration

    Författare :Magnus Sundström; Bengt Hallberg; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; HMC-1; Kit; MAP kinase; mast cells; mastocytosis; p38; SCF; TGF-β; Genetik; Clinical genetics; Klinisk genetik; Pathology; patologi;

    Sammanfattning : Mast cells are essential effector cells in the immune system as they release several inflammatory mediators. An accumulation of mast cells has been described in inflammatory conditions such as asthma and allergic rhinitis. LÄS MER

  7. 5. Flexographic Post-Printing of Corrugated Board : Contact Mechanics and Print Quality

    Författare :Erik Hallberg Hofstrand; Magnus Lestelius; Peter Rättö; Astrid Odeberg Glasenapp; D. Steven Keller; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flexography; Corrugated board; Post-printing; Contact mechanics; Print quality; Chemical engineering; Kemiteknik; Chemical Engineering; Kemiteknik;

    Sammanfattning : As the corrugated board industry strives to produce products with a higher print quality in the converting stage, there is a need for a greater understanding of the factors influencing the final print quality and how we perceive the print. In this work, a method for quantifying the print quality of printed corrugated board is presented as well as methods that quantitatively characterize the mechanical interaction between the printing form and the corrugated board in the printing nip.
