  1. 11. The Impact of Multiple Drivers on Marine Systems Novel approaches for studying structural changes

    University dissertation from Stockholm : Stockholm Resilience Centre, Stockholm University

    Author : Johanna Yletyinen; Thorsten Blenckner; Örjan Bodin; Erik Bonsdorff; Daniel Stouffer; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Natural Resources Management; naturresurshushållning;

    Abstract : Human action is transforming the species composition, biogeochemistry and habitats of the world’s oceans at unprecedented rates. The cumulative effect of natural and anthropogenic drivers is challenging to measure, in part due to indirect effects and the complexity of marine systems. READ MORE

  2. 12. Structural changes during cellulose composite processing

    University dissertation from Stockholm : Stockholm Resilience Centre, Stockholm University

    Author : Helena Halonen; Monica Ek; Tommy Iversen; Derek D. Gray; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; CP MAS 13C NMR; cellulose; fibril aggregation; biocomposite; compression moulding; supramolecular structure;

    Abstract : Two approaches for creating a new all-cellulose composite material have been studied: the biosynthesis of compartmentalised bacterial cellulose fibril aggregates and the compression moulding of commercial chemical wood pulps processed with only water. The objective was to study the structural changes during processing and the complexity of relating the mechanical properties of the final biocomposites to the nanoscale structure was highlighted.

  3. 13. Impaired reparative processes in particular related to hyaluronan in various cutaneous disorders a structural analysis

    University dissertation from Stockholm : Stockholm Resilience Centre, Stockholm University

    Author : Ulf Bertheim; Bengt Gerdin; [2004]
    Keywords : hyaluronan; scar tissue; diabetes mellitus; basal cell carcinoma; skin; wound healing; Oto-Rhino-Laryngology; oto-rhino-laryngologi;

    Abstract : Cutaneous reparative processes, including wound healing, are highly developed procedures in which a chain of actions occurs to reconstitute the function of the wounded tissue. To prevent a delayed or excessive reparative process it is important to understand how this procedure develops and is maintained. READ MORE

  4. 14. Structural Composite Lithium-Ion Battery Effect of Intercalation induced volumetric changes on micro-damage

    University dissertation from Luleå : Luleå University of Technology

    Author : Johanna Xu; Janis Varna; Andrejs Pupurs; Göran Lindbergh; Kenneth Runesson; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymeric Composite Materials; Polymera kompositmaterial;

    Abstract : The quest for lighter materials and structures to reduce climate impacts in the automotive industry has paved the way for multifunctional solutions. Mass saving on a system level can be achieved by materials or structures having more than one primary function, thus reducing the number of components used. READ MORE

  5. 15. Transthyretin from a structural perspective

    University dissertation from Umeå : Umeå centrum för molekylär patogenes (UCMP) (Teknisk-naturvetenskaplig fakultet)

    Author : Andreas Hörnberg; Elisabeth Sauer-Eriksson; Hugo Monaco; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; X-ray crystallography; amyloidosis; structural comparison; anomalous diffraction; Cell- och molekylärbiologi; NATURAL SCIENCES Biology Cell and molecular biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : Conformational changes in human proteins can induce several types of diseases. The nature of the conformational changes is largely unknown, but some lead to amyloid fibril formation. Amyloid fibrils accumulate in the extra-cellular space of tissues resulting in disruption of organ function. READ MORE
