  1. 1. Confined Compression of Single Particles : Development of a Novel Triaxial Testing Instrument and Particle-Scale Modelling

    Författare :Henrik Jonsson; Göran Frenning; Göran Alderborn; Abderrahim Michrafy; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Powder compaction; Compression; Single particle; Particle mechanics; Powder mechanics; Confined conditions; Triaxial; Apparatus design; Modelling; Galenisk farmaci; Pharmaceutics;

    Sammanfattning : When predicting the performance of a powder compaction process, assessing the behaviour of the particles comprising the powder bed is of central relevance. Currently, however, no experimental methods are available for mimicking the multiaxial loading conditions imposed on the individual particles in a powder bed during compaction, and such analyses are therefore usually performed in silico.

    Sammanfattning : This Ph.D. thesis consists of six papers, which are labeled with roman numerals. Papers I-III have already been presented in a licentiate thesis published in2017, and this Ph. LÄS MER

  4. 3. Two Problems in non-linear PDE’s with Phase Transitions

    Författare :Karl Jonsson; Henrik Shahgholian; Tomas Sjödin; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Conductivity jump; Free boundary problem; Quasilinear elliptic equation; Mathematical techniques; Nonlinear analysis; Free boundary; Free-boundary problems; Quasi-linear elliptic; Quasilinear elliptic equations; Hele-Shaw flow; non-local; implicit function theorem; Heterogeneous Multi Scale; HMM; Finite Element; FEM; FE; Mathematics; Matematik;

    Sammanfattning : This thesis is in the field of non-linear partial differential equations (PDE), focusing on problems which show some type of phase-transition. A single phase Hele-Shaw flow models a Newtoninan fluid which is being injected in the space between two narrowly separated parallel planes. LÄS MER

  5. 4. Drömmen om det ouppnåeliga : anarkistiska tankelinjer hos Hinke Bergegren, Gustaf Henriksson-Holmberg och Einar Håkansson

    Författare :Henrik Lång; Kjell Jonsson; Inga Sanner; Umeå universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; History of science and ideas; anarchism; ungsocialism; anti-authoritarianism; working-class movement; ideology; political history; violent tactics; history of social democracy; freethinkers; 19th century Sweden; Idé- och lärdomshistoria; History Of Sciences and Ideas; idé- och lärdomshistoria;

    Sammanfattning : The main purpose of this thesis is to analyze the political thought of Hinke Bergegren (1861-1936), Gustaf Henriksson-Holmberg (1864-1929) and Einar Håkansson (1883-1907), by focusing particularly on their articulation of anarchist ideas. The disseration follows these three Swedish left-wing thinkers closely, while specifically tracing ideological patterns in their published material, public discussions, speeches and other political activities.

  7. 5. Appropriate Technologies for Soil Remediation in Low Prioritized Region : Developing Countries and Sparsely Populated Regions

    Författare :Henrik Haller; Anders Jonsson; Morgan Fröling; Jaak Truu; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Soil pollution; Bioremediation; Ecotechnology; Framework for Strategic Sustainable Development; Ecological Engineering; Industrial Ecology Developing Countries; Sparsely Populated Regions; Nicaragua;

    Sammanfattning : Contaminated sites in low prioritized regions demand remediation technologies that are cost- and energy-effective and locally adapted. Parameters such as the time frame during which bioremediation degradation needs to occur may not be as restraining as in urban environments. LÄS MER
