    Sammanfattning : 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. LÄS MER

  2. 2. 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

  3. 3. Theoretical Studies of Two-Dimensional Magnetism and Chemical Bonding

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Oleksiy Grechnyev; Uppsala universitet.; [2005]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; spin Hamiltonians; quantized spin models; Heisenberg model; spin waves; self-consistent spin-wave theory; dipolar interaction; density functional theory; chemical bonding; overlap population; MAX phases; metal hydrides; Fysik; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik;

    Sammanfattning : This thesis is divided into two parts. In the first part we study thermodynamics of the two-dimensional Heisenberg ferromagnet with dipolar interaction. This interaction breaks the conditions of the Mermin-Wagner theorem, resulting in a finite transition temperature. LÄS MER

  4. 4. Nest-site attendance and foraging ecology of the Northern Fulmar (Fulmarus glacialis) on the Faroe Islands. Is the Northern Fulmar a useful indicator of ecosystem productivity and pollution?

    Detta är en avhandling från Department of Biology, Lund University

    Författare :Johannis Danielsen; Lunds universitet.; Lund University.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nest-site attendance; foraging ecology; indicator species; Fulmar; Fulmarus glacialis; nocturnal activity; ecosystem productivity; pollution; mesopelagic fish;

    Sammanfattning : Popular Abstract in English As far as we know the Northern Fulmar (just referred to as Fulmar from her on), did not start breeding on the Faroe Islands before about 150 years ago. But it has been known by the Faroese for a long time. LÄS MER

  5. 5. A Fundamental Adhesion Model for Asphalt

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Åsa Laurell Lyne; KTH.; [2014]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : One of the mechanisms for the deterioration of asphalt is debonding. This is often referred to as stripping. Most losses of adhesion at the bitumen-aggregate interface are attributed to the action of water leading to a reduction in properties such as tensile strength, tensile stiffness and wear resistance.
