  1. 31. Compaction, Flow and Dispersion in a Chromatographic Column

    Författare :Karin Östergren; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; compression; chromatography; particulate bed; hydrodynamic dispersion; theoretical model; flow field; Livsmedelsteknik;

    Sammanfattning : An experimental and theoretical study of compaction, flow and hydrodynamic dispersion in a chromatographic column containing non-rigid particles is presented. Experiments were performed using chromatographic columns packed with either a dextran-based chromatographic gel or glass beads. LÄS MER

    Sammanfattning : In this thesis, factors important in tableting operations and for tablet properties have been studied and characterised by different spectroscopic techniques as well as by some more conventionally used particle characterisation techniques. The spectroscopic techniques solid-state NMR, FT-IR and NIR spectroscopy, proved to be valuable tools in the estimation of particle and tablet properties, offering both specificity and sensitivity in the measurements.

  7. 35. Analyses of Resilient Behavior of Unbound Materials for the Purpose of Predicting Permanent Deformation Behavior

    Författare :Jan Englund; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Permanent Deformation; Unbound Material; Resilient Deformation; Post Compaction; Falling Weight Deflectometer FWD ; Triaxial Testing; Heavy Vehicle Simulator HVS ; Modulus;

    Sammanfattning : Post compaction is the unintended compaction of the unbound material that commences immediately after a road is brought into service and caused by densification of the material. Analogies to this post compaction can also be seen in laboratory and field tests. LÄS MER
