• Computational stability of an intially radial solution of a growth/dissolution problem in a nonradial implementation 

  Jensen, Søren; Laitinen, Erkki; Neittaanmäki, Pekka; Seidman, Thomas (Birkhäuser, 1991)

  We consider a free boundary problem modelling the growth/dissolution of a crystal. The aim is to investigate the following question: Does the solution to the crystal growth problem posed in two dimensions with radially ...

• The effect of experimental conditions on the performance of a small-scale dissolution-permeation model in drug development 

  Hiidenhovi, Sara (2022)

  Useimmat uudet lääkeaineet ovat heikosti liukenevia ja lääkeaineen määrä lääkekehityksessä on hyvin rajallinen. Sen vuoksi on tarve löytää uusia liukoisuutta parantavia formulaatioita ja pienen mittakaavan metodeja ja ...

• Dissolution and hydrolysis of fibre sludge using hydroxyalkylimidazolium hydrogensulphate ionic liquids 

  Dong, Yue; Holm, Jana; Kärkkäinen, Johanna; Nowicki, Janusz; Lassi, Ulla (Pergamon, 2014)

  The dissolution and hydrolysis of wet fibre sludge in ionic liquids (ILs) with different reaction conditions are performed in this study. Novel types of hydroxyalkylimidazolium hydrogensulphate ILs, [glymim]HSO4, [hemim]HSO4 ...

• Dissolution behavior of co-amorphous amino acid-indomethacin mixtures : The ability of amino acids to stabilize the supersaturated state of indomethacin 

  Ojaranta, Rami; Heikkinen, Aki T.; Sievänen, Elina; Laitinen, Riikka (Elsevier BV; Arbeitsgemeinschaft fuer Pharmazeutische Verfahrenstechnik e.V., 2017)

  Arginine, phenylalanine, and tryptophan have been previously shown to improve the solid-state stability of amorphous indomethacin. The present study investigates the ability of these amino acids to prolong the supersaturation ...

• Partnership formation and dissolution over the life course: Applying sequence analysis and event history analysis in the study of recurrent events 

  Helske, Satu; Steele, Fiona; Kokko, Katja; Räikkönen, Eija; Eerola, Mervi (Society for Longitudinal and Life Course Studies, 2015)

  We present two types of approach to the analysis of recurrent events for discretely measured data, and show how these methods can complement each other when analysing co-residential partnership histories. Sequence analysis ...
