  1. 41. Drowning-out crystallisation of benzoic acid : Influence of processing conditions and solvent composition on crystal size and shape

    Författare :Xiomara Holmbäck; KTH; []
    Nyckelord :solvent effect; drowning-out; crystallization; benzoic acid; solubility; crystal habit; crystal growth; interfacial energy; growth mechanism;

    Sammanfattning : The aim of the present investigation is to increase theunderstanding of the role played by the solvent in inhibitingor enhancing crystal growth. Drowning-out crystallizationexperiments has been performed by the controlled addition ofwater or ethanol water mixtures to a saturated solution ofbenzoic acid in ethanol-water mixtures. LÄS MER

  3. 42. A paleolimnological perspective on liming – implications for defining reference conditions in Swedish lakes

    Författare :Matilda Norberg; Ingemar Renberg; Helen Bennion; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Acidification; Liming; European Water Framework Directive; Reference condition; Diatoms; Paleolimnology; Monitoring; Lake sediments; Earth sciences; Geovetenskap; Earth Sciences with Specialization Environmental Analysis; geovetenskap med inriktning mot miljöanalys;

    Sammanfattning : Using paleolimnological techniques, I have studied surface-water acidification and the effects of liming in Swedish lakes on a decadal to millennial time-scale. The overall objective was to contribute to the discussion on the fulfilment of goals within the Swedish liming program. LÄS MER

  4. 43. Mass Transport in Apple Tissue: Effects of Tissue Structure and Osmotic Processing Conditions

    Författare :Nikolaos Mavroudis; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; Livsmedelsteknik; drying; porosity; shrinkage; cell vitality; apple structure; apple; osmotic processing; mass transport; mass transport mechanisms;

    Sammanfattning : Osmotic processing can be a very useful processing step in today’s food industry enabling the production of high quality natural food ingredients out of plant tissues. The maintenance of high product quality is quite product specific with regard to quality attributes. These attributes include fresh/like appearance, taste, texture and composition. LÄS MER

  5. 44. The influence of Pulp Type and Hot-pressing Conditions on Paper Strength Development

    Författare :Tove Joelsson; Per Engstrand; Gunilla Pettersson; Anna Svedberg; Tom Lindström; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hot pressing; lignin; HYP; high strength; wet strength; softening temperature; kraft pulp; lignocellulose;

    Sammanfattning : The hot-pressing technology has proven to have the potential for manufacturing of strong, wet stable materials based on eco-friendly renewable and recyclable lignocellulose. The purpose of this work was to study how the pulp characteristics and the hot-pressing conditions affect the dry and wet strength properties of paper. LÄS MER
