  1. 1. Lime Mud Reburning. Properties and Quality of the Lime Produced

    Författare :Charlotta Hanson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : It is of utmost importance that the white liquor used in the digester of a sulphate pulp mill is of high quality. The white liquor is prepared in the causticizing plant, through causticizing of the sodium carbonate in the green liquor. LÄS MER

  3. 2. Investigating ruminal nitrogen metabolism : in vitro and in vivo studies using ¹⁵N-labelled forage nitrogen fractions

    Författare :Merko Vaga; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Nitrogen losses from dairy production have negative impacts on the environment and on production economics. In Northern Europe, dairy cattle are mainly fed forage-based diets supplemented with protein feeds such as rapeseed meal. LÄS MER

  4. 3. Novel Technique for Analysing Volatile Compounds in Indoor Dust : Application of Gas Chromatography – UV Spectrometry to the Study of Building-Related Illness

    Författare :Anders Nilsson; Christer Tagesson; Verner Lagesson; Göran Strid; Linköpings universitet; []
    Nyckelord :acrylates adverse effects; air pollution; ultraviolet; indoor analysis; chromatography; gas; environmental exposure adverse effects; sick building syndrome etiology; dust; volatilization; Spectrophotometry; MEDICINE; MEDICIN;

    Sammanfattning : It is now generally acknowledged that particulate air pollution can cause respiratory symptoms and that indoor dust particles may be associated with mucous membrane irritation and odour annoyance. One reason for this may be that dust particles adsorb large quantities of gases and other volatile compounds. LÄS MER

  5. 4. Towards better understanding of the flow inside industrial processes: a CFD study

    Författare :Simon Johansson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Sammanfattning : Computational Fluid Dynamics (CFD) is a method to numerically pre- dict flow patterns. In this thesis the method is used to predict the flow in a hydrochloric acid regeneration plant located at SSAB EMEA in Borl ̈ange and to investigate the flow in a burner region of a rotary kiln at LKAB in Kiruna.

  7. 5. Porous materials based on nanopolysaccharides for medical applications: Effect of crosslinking on pore structure and mechanical performance

    Författare :Narges Naseri; Orlando Rojas; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trä och bionanokompositer; Wood and Bionanocomposites;

    Sammanfattning : The objective of this work was to develop nanochitin- and nanocellulose-based crosslinked porous nanostructured materials for wound dressing and cartilage repair with suitable porosity and mechanical properties to facilitate cell growth. In the first part of the work (papers I-III), chitosan-based nanocomposites loaded with a high concentration (50 wt%) of chitin nanocrystals (ChNC) and cellulose nanocrystals (CNC) were prepared via electrospinning for use as wound dressing materials.
