  1. 1. Prediction of wood species and pulp brightness from roundwood measurements

    Author : David Nilsson; Ulf Edlund; Michael Sjöström; Olav Kvalheim; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Design of Experiments; ISO brightness; Multivariate Image Analysis; Multivariate Modelling; NIR spectroscopy; Norway spruce; PCA; PLS; Roundwood; Scots pine; Organic chemistry; Organisk kemi;

    Abstract : This thesis presents a number of studies, where a multivariate approach was taken to construct models that predict wood species and thermo mechanical pulp brightness from roundwood of Norway spruce and Scots pine. The first and second studies produced multivariate prediction models for wood species from the bark of spruce and pine. READ MORE

    Abstract : Diabetes is a rapidly growing disease with 415 million affected adults worldwide. The pancreatic endocrine cells, most importantly the insulin producing β-cells, play an important role in regulating blood glucose homeostasis. READ MORE

  3. 3. Innate Confinement Effects in PCL Oligomers as a  Route to Confined Space Crystallisation

    Author : Nima Sanandaji; Ulf W. Gedde; Mikael Hedenqvist; Lars Kloo; Ulrica Edlund; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Crystallisation; Polycaprolactone; PCL; Confined state crystallisation; Metastable Phases; Chemistry; Kemi;

    Abstract : In this work, an in-depth analysis of crystalline characteristics has been performed for a unique set of strictly monodisperse poly-ε-caprolactone (PCL) oligomers. The molecules have different sets of end groups with various degrees of bulkiness and hydrogen bonding potential, affecting their aptitude to pack in ordered crystal structures. READ MORE

  4. 4. Spectroscopic data and multivariate analysis : tools to study genetic perturbations in poplar trees

    Author : Susanne Wiklund; Ulf Edlund; Olav Kvalheim; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NMR spectroscopy; Metabolomics; Degree of methylation; S-plot; SUS-plot; Metabonomics; Poplar; MLR; PLS; OPLS; PCA; Pectin; Wood; Organic chemistry; Organisk kemi;

    Abstract : In our society in the 21st century one of the greatest challenges is to provide raw materials to the industry in a sustainable way. This requires increased use of renewable raw materials such as wood. Wood is widely used in pulp, paper and textile industries and ongoing research efforts aim to extend the use of wood in e.g. READ MORE
