  2. 26. Interactions between polyphenols and macromolecules facilitate the extraction of low viscosity banana juice

    Author : Nuria Majaliwa; Chalmers tekniska högskola; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; response surface methodology; polyphenols; banana juice; East African Highland bananas; Fourier Transform Infrared spectroscopy; protein distributions;

    Abstract : Bananas are an important staple food and cash crop throughout the African Great Lakes region where they contribute highly to livelihood and food security. However, bananas are perishable fruits that require effective processing techniques to reduce post-harvest losses. READ MORE

  4. 27. Quantitative genetics of wood quality traits in Scots pine

    Author : Irena Fundová; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Wood quality of commercial tree species is important for many wood processingindustries and thus should be considered for inclusion in forest tree improvementprograms. This thesis evaluated the suitability of various proxy methods for rapid andnon-destructive assessment of wood quality traits on standing trees of Scots pine and thepotential for genetic improvement of different wood quality traits through recurrentselective breeding.

    Keywords : Hydroxyacrylate-melamine copolymer; cellulose nanocrystals CNC ; cellulose nanofibrils CNF ; Electrochemical impedance spectroscopy EIS ; atomic force microscopy AFM ; corrosion protection performance; water uptake; nanomechanical and nano-wear properties; coating; nanocomposite.; Hydroxyakrylat-melamin-sampolymer; cellulosananokristaller CNC ; cellulosananofibriller CNF ; Elektrokemisk impedansspektroskopi EIS ; atomkraftsmikroskopi AFM ; korrosionsskyddsprestanda; vattenupptag; nanomekaniska egenskaper och nano-slitage; coating; nanokomposit.; Kemi; Chemistry;

    Abstract : Corrosion protection is commonly achieved by applying a thin polymer coating on metal surfaces. In this doctoral thesis, a waterborne hydroxyacrylate-melamine copolymer coating was used for this purpose. The first step was to find the optimal curing conditions. READ MORE

  6. 29. Fundamental Aspects on the Re-use of Wood Based Fibres : Porous Structure of Fibres and Ink Detachment

    Author : Jennie Forsström; Lars Wågberg; Krrister Holmberg; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; Miljöteknik; Environmental engineering; Miljöteknik;

    Abstract : In this work, different aspects on the re-use of wood based fibres have been studied, focusing on ink detachment of flexographic ink from model cellulose surfaces and changes in porous structure of kraft fibres following different treatments. New model systems for evaluation of ink detachment and ink-cellulose interactions were used. READ MORE
