  1. 1. Distributions Of Fiber Characteristics As A Tool To Evaluate Mechanical Pulps

    Detta är en avhandling från Sundsvall : Mid Sweden University

    Författare :Sofia Reyier Österling; Mittuniversitetet.; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fiber; fibre; fiber characteristics; fiber dimension; fiber properties; mechanical pulp; FiberLab; raw data; distribution; fiber wall thickness; BIN; bonding ability influence; bonding indicator; bonding ability; fiber width; fibrillation; collapse resistance; laboratory sheet; fiber analyzer; optical analyzer; TMP; CTMP; SGW; sheet model; prediction; fiber characterization; hydrocyclone; fractionation; kernel density estimation; KDE; diffusion mixing; acoustic emission; F0.90; Norway spruce; Picea abies;

    Sammanfattning : Mechanical pulps are used in paper products such as magazine or news grade printing papers or paperboard. Mechanical pulping gives a high yield; nearly everything in the tree except the bark is used in the paper. This means that mechanical pulping consumes much less wood than chemical pulping, especially to produce a unit area of printing surface. LÄS MER

  2. 2. Wear in sheet metal forming

    Detta är en avhandling från Karlstad : Karlstad University

    Författare :Anders Gåård; Karlstads universitet.; Karlstads universitet.; Karlstads universitet.; [2008]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap; Materialteknik; Materials Engineering; Friction; Sheet metal forming; Galling;

    Sammanfattning : The general trend in the car body manufacturing industry is towards low-series production and reduction of press lubricants and car weight. The limited use of press lubricants, in combination with the introduction of high and ultra-high strength sheet materials, continuously increases the demands of the forming tools. LÄS MER

  3. 3. Wear mechanisms in sheet metal forming Effects of tool microstructure, adhesion and temperature

    Sammanfattning : The general trend in the car body manufacturing industry is towards low-series production and reduction of press lubricants and car weight. The limited use of lubricants, in combination with the introduction of high and ultrahigh-strength sheet materials, continuously increases the demands on the forming tools. LÄS MER

  4. 4. Structure-function studies of plasminogen activator inhibitor-1

    Detta är en avhandling från Stockholm : Karolinska Institutet, Department of Laboratory Medicine

    Författare :Guang-Chao Sui; Karolinska Institutet.; Karolinska Institutet.; [1998]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PAI-1; site-directed mutagenesis; structure and function; stability;

    Sammanfattning : Plasminogen activator inhibitor-I (PAI-1) is an important physiological inhibitor of tissue-type plasminogen activator (tPA) and urine-type plasminogen activator (uPA). High plasma levels of PAI-1 correlate to thrombotic disease, and low levels can be connected to a bleeding tendency. LÄS MER

  5. 5. Anti-infectious and anti-inflammatory activities of lactoferrin and fragments thereof

    Detta är en avhandling från Göteborg

    Författare :Liliana Håversen; Göteborgs universitet.; Gothenburg University.; Göteborgs universitet.; Gothenburg University.; [2002]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Lactoferrin (LF), a major protein present in milk, mucosal secretions and secondary granules of neutrophils, has been suggested to participate in host defense at mucosal surfaces and to mediate anti-inflammatory activities. A pepsin-derived fragment of LF has been shown to contain the antibacterial domain of the protein. LÄS MER
