  1. 16. Dissolving pulp : Multivariate Characterisation and Analysis of Reactivity and Spectroscopic Properties

    Författare :Kristina Elg Christoffersson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Dissolving pulp; reactivity; solid state 13C NMR spectroscopy; NIR spectroscopy; multivariate analysis; cellulose; viscose; Kemi; Chemistry; Kemi;

    Sammanfattning : Various chemical properties can be used to characterise dissolving pulp. The quality of the pulp must be carefully controlled to ensure that it meets the requirements for its intended use and the further processes to be applied. LÄS MER

  3. 17. Medieval Timber Roof Structures: Conceptual methods for investigation and evaluation of structural behaviour, with the horizontal thrust problem as an application

    Författare :Carl Thelin; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; conservation; thrust; medieval churches; preservation; structural behaviour; base of the roof; roof truss; roof structure; horizontal support; FEM;

    Sammanfattning : The medieval timber roof structures hidden in the attics of many Swedish churches represent the advanced building technology of the time. They are an important cultural heritage, their being bearers of information from a period regarding which other direct sources of information are scarce. LÄS MER

  4. 18. Spin-Orbit and Spin-Spin Coupling in the Triplet State

    Författare :Sathya Sai Ramakrishna Raj Perumal; Hans Ågren; Ulf Wahlgren; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Spin-spin; Spin-Orbit; D and E parameters; ZFS; graphene; TMM; OXA; diradicals; tris 8-hydroxyquinonline aluminium; magnetic anisotropy; magnetism; triplet;

    Sammanfattning : The underlying theory of “Spin” of an electron and its associated inter-actions causing internal fields and spectral shift to bulk-magnetism iswell established now. Our understanding of spin properties is significant andmore useful than ever before. LÄS MER

  5. 19. Cryptographic Tools for Privacy Preservation

    Författare :Carlo Brunetta; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Outsourced Computation; Verifiability; Cryptography; Privacy; Cloud Computing;

    Sammanfattning : Data permeates every aspect of our daily life and it is the backbone of our digitalized society. Smartphones, smartwatches and many more smart devices measure, collect, modify and share data in what is known as the Internet of Things. LÄS MER

  7. 20. Taxonomy and Reticulate Phylogeny of Heliosperma and Related Genera (Sileneae, Caryophyllaceae)

    Författare :Božo Frajman; Bengt Oxelman; Mats Thulin; Christian Brochmann; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sileneae; Silene; Heliosperma; Atocion; Viscaria; taxonomy; phylogenetics; relative dating; reticulate evolution; chloroplast capture; homoploid hybridisation; BEAST; r8s; PATHd8; Prometheus; RPA2; RPB2; RPD2a; RPD2b; Balkan Peninsula; endemics; Systematics and phylogenetics; Systematik och fylogeni;

    Sammanfattning : Heliosperma (nom. cons prop.) comprises 15—20 taxa, most of them endemic to the Balkan Peninsula. DNA sequences from the chloroplast (rps16 intron, psbE-petG spacer) and the nuclear genome (ITS and four putatively unlinked RNA polymerase genes) are used to elucidate phylogenetic relationships within Heliosperma, and its position within Sileneae.
