  1. 1. Comparison of properties on Orally Disintegrating Tablets (ODTs) produced by direct compression or fluid bed granulation

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Julia Ahlbom; [2023]
    Keywords : Orally disintegrating tablet; fluid bed granulation; disintegration time; pharmaceutical technology; Technology and Engineering;

    Abstract : Orally disintegrating tablets (ODTs) is a popular drug delivery system as they dissolve in the mouth, usually within seconds which enables easy medication for patients with problem swallowing. In this thesis properties of ODTs were compared when produced with direct compression of the excipients or the excipients were pretreated to form granules in a fluid bed granulator prior to tableting.

  6. 5. Statistical Analysis and Modelling of Engine Oil Degradation

    University essay from Umeå universitet/Institutionen för fysik

    Author : Nils Bastiampillai; [2023]
    Keywords : ;

    Abstract : An engine oil has several important properties it must fulfil in order to provide efficient engine operation. In addition to damping friction by lubrication, an engine oil must be able to cool, protect against corrosion, dampen vibrations and clean surfaces from contamination, wear and residual products.
