  1. 1. Aspects of Flexographic Print Quality and Relationship to some Printing Parameters

    Författare :Johanna Johnson; Lars Järnström; Magnus Lestelius; Peter Rättö; Erik Blohm; Jouko Peltonen; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flexography; Print Quality; Liner; Board; Newsprint; Water-borne ink; Dynamic Pressure; Plate Properties; Wetting; Chemical engineering; Kemiteknik; Chemical Engineering; Kemiteknik;

    Sammanfattning : Flexographic printing is a common printing method in the packaging field. The printing method is characterized primarily by the flexible printing plate and the low viscosity inks which make it suitable for use on almost any substrate. LÄS MER

  2. 2. Micro-structural based acoustic modelling of anisotropic open cell materials

    Författare :Eva Lundberg; Huina Mao; Bradley Semeniuk; Peter Göransson; Mathieu Gaborit; Romain Rumpler; Peter Göransson; Elke Deckers; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sound absorption; vehicle; anisotropic; foam; micro-structure; resource efficient; transfer matrix method; ljudabsorption; anisotrop; skum; mikrostruktur; TMM; fordon; resurseffektiv; Farkostteknik; Vehicle and Maritime Engineering;

    Sammanfattning : A method for the calculation of the acoustic performance of open-cell foammaterials is discussed. From a known micro-structural geometry and theconstituent material, the relevant acoustic properties are computed using apreviously published analytical method for the calculation of the dynamicdrag impedance and a previously published method for the calculation of theelastic moduli.

  3. 3. Bias and Precision in Biomechanical Exposure Assessment : Making the Most of our Methods

    Författare :Jennie Jackson; Svend Erik Mathiassen; Eva Vingård; Mikael Forsman; Peter Johnson; Högskolan i Gävle; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; measurement strategy; accuracy; inclinometry; electromyography; EMG; upper arm; shoulder; low back; lumbar; thoracic; Health-Promoting Work; Hälsofrämjande arbete;

    Sammanfattning : Background: Insufficient exposure assessment is a suggested contributing factor to the current lack of clearly characterised relationships between occupational biomechanical risk factors and musculoskeletal disorders. Minimal attention has been paid to the potential bias of measurement tools from expected true values (i.e. LÄS MER

  4. 4. Ecological and Evolutionary Consequences of Herbivory in the Perennial Herb Lythrum salicaria

    Författare :Lina Lehndal; Jon Ågren; Peter Hambäck; Marc Johnson; Uppsala universitet; []
    Nyckelord :Disturbance gradient; Female reproductive success; Galerucella calmariensis; Galerucella pusilla; Herbivore removal; Latitudinal gradient; Local adaptation; Nanophyes marmoratus; Plant-herbivore interactions; Plant size; Resistance to herbivory; Tolerance to damage; Biology with specialization in Ecological Botany; Biologi med inriktning mot ekologisk botanik;

    Sammanfattning : In this thesis, I combined field, common-garden and greenhouse experiments to examine the ecological and evolutionary consequences of plant-herbivore interactions in the perennial herb Lythrum salicaria. More specifically I examined (1) whether resistance and tolerance to damage from herbivores vary with latitude and are positively related to the intensity of herbivory in natural populations, (2) whether effects of herbivory on plant fitness vary with latitude, (3) whether populations are locally adapted and whether herbivory influences the relative fitness of populations, and (4) whether the intensity and effects of insect herbivory on reproductive output vary locally along a disturbance gradient and are associated with differences in plant resistance.

  5. 5. A Real Property Register to Support the Property and Credit Market in Uganda

    Författare :Lilian Mono Wabineno Oryema; Peter Ekbäck; Hans Mattsson; Moses Musinguzi; Eva Johnson Liedholm; Jaap Zevenbergen; KTH; []
    Nyckelord :Property Rights; Real Property Register; Property Market; Credit Market; Uganda; Rättigheter; Fastighetsregister; Fastighetsmarknad; Kreditmarknad; Uganda.; Real Estate and Construction Management; Fastigheter och byggande;

    Sammanfattning : An efficient property and credit market can be used by a government of a country to empower its citizens to achieve sustainable development. To improve the property and credit market government needs to ensure that its land records contain information that is beneficial to the actors in both the property and credit market. LÄS MER
