    Författare :Leif Olsson; Mittuniversitetet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Stochastic Programming; Scenario Analysis; Mixed-Integer Linear Programming; Forest Logistics; Upgrading of gravel roads; Business studies; Företagsekonomi; MATHEMATICS; MATEMATIK;

    Sammanfattning : In a pre-study, concerning roundwood freshness, performed by the Forestry Research Institute of Sweden during the spring of 2000, the quality on the forest road network was identified as a major problem for the Swedish forest sector. These problems mostly occur during spring thaw, but also when rains give muddy gravel roads. LÄS MER

  2. 2. Alfabetets användning : Konkret poesi och poetisk artefaktion i svenskt 1960-tal

    Författare :Jesper Olsson; Kerstin Dahlbäck; Tania Ørum; Anders Olsson; Stockholms universitet; []
    Nyckelord :HUMANITIES; HUMANIORA; HUMANIORA; HUMANITIES; Concrete poetry; Artifice; Materiality; Media technologies; Visual poetry; Sound. Noise; Cybernetics; The Sixties; Öyvind Fahlström; Jarl Hammarberg; Åke Hodell; Bengt Emil Johnson; Leif Nylén; Carl Fredrik Reuterswärd; Literature; Litteraturvetenskap; Concrete poetry;

    Sammanfattning : The subject of this dissertation is the so-called concrete poetry that was written in Sweden during the 1960s and, to a small extent, in the 1950s, by Öyvind Fahlström, Jarl Hammarberg, Åke Hodell, Bengt Emil Johnson, and others. The study is focused on a discussion of the forms and the ways of writing that were explored, but it also gives an account of the aesthetic-historical context – of the expanded field of the arts in the 1960s, of the early avant-garde, of related forms of writing in earlier literature, such as pattern poetry.

  3. 3. Nanocomposites of Cellulose and Conducting Polymer for Electrical Energy Storage

    Författare :Henrik Olsson; Leif Nyholm; Maria Strømme; Martin Sjödin; Johan Bobacka; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Polypyrrole; Nanocomposites; Energy storage; Conducting polymers; Cellulose; Engineering Science with specialization in Nanotechnology and Functional Materials; Teknisk fysik med inriktning mot nanoteknologi och funktionella material;

    Sammanfattning : The world’s increased energy storage demand, as well as the environmental concerns related to the combustion of fossil fuels, has triggered a transition to intermittent renewable energy sources as well as to electrical and hybrid vehicles. Current day rechargeable batteries are, due to the invention and development of lithium ion batteries, technologically well positioned to answer to some of these demands. LÄS MER

  4. 4. Low Frequency Impact Sound in Timber Buildings : Simulations and Measurements
