  1. 1. Bonding Ability Distribution of Fibers in Mechanical Pulp Furnishes

    Author : Sofia Reyier; Per Engstrand; Hans Höglund; Olof Ferritsius; Hans Ersson; Rita Ferritsius; Philip Reme; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fiber; mechanical pulp; bonding ability; fiber characterization; Bonding Indicator; BIN; acoustic emission; hydrocyclone; Fiberlab; collapse resistance; fibrillation; Fiber; mekanisk massa; bindningsförmåga; fiber karakterisering; Bindnings Indikator; BIN; akustisk emission; hydrocyklon; Fiberlab; kollaps resistans; fibrillering; TECHNOLOGY Chemical engineering Chemical process and manufacturing engineering Cellulose and paper engineering; TEKNIKVETENSKAP Kemiteknik Kemisk process- och produktionsteknik Cellulosa- och pappersteknik;

    Abstract : This thesis presents a method of measuring the distribution of fiber bonding ability in mechanical pulp furnishes. The method is intended for industrial use, where today only average values are used to describe fiber bonding ability, despite the differences in morphology of the fibers entering the mill.

  2. 2. From bio-based residues to nanofibers using mechanical fibrillation for functional biomaterials

    University dissertation from Luleå University of Technology

    Author : Linn Berglund; Kristiina Oksman; Monika Österberg; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanofibers; Industrial residues; Ultrafine grinding; Energy-efficiency; Network formation; Hydrogel; Trä och bionanokompositer; Wood and Bionanocomposites;

    Abstract : Bio-based resource utilization in different forms has been driven by societal, industrial and academic research interests towards the development of “green”, sustainable materials from renewable sources. Within this context, exploiting biomass from different industrial residues is further advantageous from an environmental and economic point of view, leading to minimization of residues by means of waste treatment and to the development of high-addedvalue- products.

  3. 3. Collagen VI - Molecular Assembly and Interactions

    University dissertation from Charlotte Wiberg, Dep of Cell and Molecular Biology, BMC Plan C12, SE-221 84 Lund, Sweden

    Author : Charlotte Wiberg; [2001]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clinical biology; extracellular matrix; glycosaminoglycan; proteoglycan; collagen; biglycan; decorin; Klinisk biologi;

    Abstract : The extracellular matrix plays an integral role in tissue remodeling and development and it defines the different mechanical properties of a variety of connective tissues. Its complexity in composition and the details in organization has only been partly elucidated. READ MORE

  4. 4. Basement membrane components in the chondrocyte extracellular matrix

    University dissertation from Lund University: Faculty of Medicine

    Author : Alexander Kvist; [2007]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Skelett; rheumatology locomotion; nidogen; chondroitin sulfate; collagen assembly; Skeleton; muscle system; type IV collagen; laminin; perlecan; basement membranes; ECM; chondrcytes; muskelsystem; reumatologi;

    Abstract : The extracellular matrix (ECM) is a network of macromolecules which, together with cells, forms the various tissues of all metazoan organisms. Cartilage, in contrast to most other tissues, contains relatively few cells in proportion to the volume occupied by ECM. READ MORE

  5. 5. Improved energy efficiency in double disc chip refining

    University dissertation from Sundsvall : Mittuniversitetet

    Author : Dino Muhic; Per Engstrand; Lars Sundström; Mats Ullmar; Christer Sandberg; Hans Höglund; [2010]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermomechanical pulping TMP ; double disc refining; high intensity; TECHNOLOGY Chemical engineering; TEKNIKVETENSKAP Kemiteknik;

    Abstract : The electrical energy consumption in thermomechanical pulping (TMP) is very high, in the range of 2 – 3 MWh/adt depending on process solution and on the product quality specifications for the paper product. Both pulpwood and energy prices have increased rapidly for some time. READ MORE
