  1. 1. Fuel conversion and ash formation interactions a thermochemical study on lignocellulosic biomass

    University dissertation from Umeå : Umeå Universitet

    Author : Anna Strandberg; Umeå universitet.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Char conversion; pyrolysis; devolatilization; ash transformation; biomass; fuel characterization; fuel composition; ash composition; silicate formation; carbonate formation; thermogravimetric analysis; micro-tomography;

    Abstract : Biomass is considered to be CO2 neutral, and to be able to reduce the dependency on fossil fuels the need for expanded and sustainable biomass feedstock is increasing. Ash-related problems are some of the most important aspects of this increasing use of new biomass assortments in thermal energy conversion systems. READ MORE

  2. 2. Modern Icelandic Word Formation

    University dissertation from Uppsala : Institutionen för nordiska språk

    Author : Yair Sapir; Uppsala universitet.; [2003]
    Keywords : HUMANIORA; HUMANITIES; Icelandic language; Icelandic; Scandinavian; word formation; morphology; neologisms; calque; language planning; language contact; linguistic purism; Isländska; HUMANITIES and RELIGION Languages and linguistics Scandinavian languages; HUMANIORA och RELIGIONSVETENSKAP Språkvetenskap Nordiska språk;

    Abstract : Icelandic is known for its conservative word formation, largely involving native sources. The main focus of the present research is to describe which mechanisms are used in forming words in Modern Icelandic. Furthermore, a postulated additional category within Icelandic complexes, introduced here under the label compilations, is examined. READ MORE

  3. 3. Dissipative formation of galaxies in hierarchical cosmology

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : John Hultman; Uppsala universitet.; [1998]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Astronomy; merical methods; hydrodynamics; galaxies: formation; galaxies: elliptical; galaxies: structure; star formation; Astronomi; NATURAL SCIENCES Physics Astronomy and astrophysics; NATURVETENSKAP Fysik Astronomi och astrofysik; Theoretical Astrophysics; teoretisk astrofysik;

    Abstract : A description and detailed tests of a numerical code for simulations of galaxy formation is presented. The dynamics is followed with fully adaptive and Lagrangian Smooth Particle Hydrodynamics (SPH) combined with a gravitational tree method. The severe numerical problem of sub-resolution clustering is solved by merging of gas particles. READ MORE

    Abstract : Popular Abstract in Swedish En amfifil molekyl innebär en molekyl som består av två delar, en som är hydrofil (“vattenälskande”) och en som är hydrofob (“vattenhatande”). Ofta består den amfifila molekylen av en ”vattenälskande” huvudgrupp och en ”vattenhatande” svans och kallas för surfaktant. READ MORE
