  1. 21. Colloidal Processing and Alignment of Wood-Based Dispersions and Hybrid Functional Foams

    Författare :Seyed Ehsan Hadi; Lennart Bergström; Daniel Söderberg; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wood-based nanomaterials; process-structure-property relationships; nanocellulose; lignocellulose nanofibers; rheology; small-angle X-ray scattering; lignin; tannic acid; unidirectional ice-templating; foams; aerogels; sustainability; träbaserade nanomaterial; process-struktur-egenskapsrelationer; nanocellulosa; lignocellulosananofibrer; reologi; småvinkelröntgenstrålning; lignin; garvsyra; riktad isstrukturering; skum; aerogeler; hållbarhet; materialkemi; Materials Chemistry;

    Sammanfattning : This thesis presents novel methods and approaches for designing, preparing/fabricating, and characterizing wood-based nanomaterials. It investigates how modifications in structure, process variables, and composition can enhance functional properties. LÄS MER

  3. 22. Opinionens mekanismer : Om värderingar och verklighet

    Författare :Torsten Österman; Stefan Svallfors; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Sociology; Sociologi; Sociology; sociologi;

    Sammanfattning : A significant characteristic of our time is the accelerating speed and increased volume ofinformation, where events and information about events form an interacting dynamo. The traitsand abilities of individuals and society to handle and respond to that flow of informationdeserve political attention. LÄS MER

  4. 23. Ion pairing and Langmuir-like adsorption at aqueous surfaces studied by core-level spectroscopy

    Författare :Victor Ekholm; Olle Björneholm; Jan-Erik Rubensson; Markus Ammann; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; XPS; Surface; Aqueous; Liquid jet; Langmuir;

    Sammanfattning : Surface-bulk equilibria for solutes in aqueous solutions are studied using X-ray Photoelectron Spectroscopy (XPS) with high surface and chemical sensitivity. In the first part, the results show a reduction of the biochemically relevant guanidinium ions’ surface propensity with the addition of disodium sulphate due to ion pairing with the strongly hydrated sulphate ion, which could have implications for protein folding.

  5. 24. Three dimensional mathematical modelling of pronuclei migration for the mouse

    Författare :Sofia Tapani; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; fertilisation process; pronucleus; dynamical simulation; SDE; correlation; CUSUM; microtubule; confocal microscopy; dynamical simulation;

    Sammanfattning : The main question addressed in this thesis is what happens between the moment when the sperm enters the egg and the fusion of the male and the female pronuclei. Orientation of the apposing pronuclei most likely plays a decisive role in the polarity of the developing embryo. LÄS MER

  7. 25. Views of Nature and Environmental Concern in Iceland

    Författare :Þorvardur Árnason; Elfar Loftsson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Views; Nature; Environmental; Concern; Ethics; Iceland; Miljöhistoria; Island; Naturuppfattning; Naturskydd; Historia; Water in nature and society; Vatten i natur och samhälle;

    Sammanfattning : Environmental concern in contemporary societies is a complex phenomenon which is shaped and influenced by a host of different factors. One of the most important of these is the interplay between culture and nature that has taken place during the course of a nation’s history and the various ‛views of nature’ that such interplay has generated.
