  1. 16. The effect of dry period length on milk production, health and fertility in two cow breeds

    Författare :Elisabeth Andrée O´ Hara; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : The transition from not producing milk during the dry period to the huge nutrient demands as milk production rapidly increases after parturition imposes significant metabolic strain on high-yielding dairy cows. The drying-off procedure is also demanding and high milk yield at dry-off increases the risk of mastitis and metabolic problems. LÄS MER

  2. 17. Structural Composite Lithium-Ion Battery : Effect of Intercalation induced volumetric changes on micro-damage

    Författare :Johanna Xu; Janis Varna; Andrejs Pupurs; Göran Lindbergh; Kenneth Runesson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera kompositmaterial; Polymeric Composite Materials;

    Sammanfattning : The quest for lighter materials and structures to reduce climate impacts in the automotive industry has paved the way for multifunctional solutions. Mass saving on a system level can be achieved by materials or structures having more than one primary function, thus reducing the number of components used. LÄS MER

  3. 18. Molecular studies of initial atmospheric corrosion of copper : Exploration of ultra-sensitive techniques for the inhibiting effect of self assembled monolayers, and the effect of gamma radiation

    Författare :Saman Hosseinpour; Christofer Leygraf; Franz Geiger; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Corrosion; copper; self assembled monolayer; sum frequency spectroscopy; qcm; gamma radiation;

    Sammanfattning : Atmospheric corrosion indoors is of great practical importance for the degradation of metals, for example in electronics, military equipment, and cultural heritage items. It involves a wide range of chemical, electrochemical, and physical processes occurring in gas, liquid, and solid phases, and at the interfaces between them. LÄS MER

  4. 19. Probabilistic System Effects in Timber Structures

    Författare :Martin Hansson; Avdelningen för Konstruktionsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggnadsteknik; Building construction; Anläggningsteknik; Construction technology; first order reliability method; Monte Carlo simulation; system effect; sheathed parallel member system; structural timber; roof truss;

    Sammanfattning : The main purpose of the performed research presented in this thesis is to increase the understanding of the effect of variability of strength properties on the reliability of timber structural systems. Compared to other structural materials such as steel and concrete, structural timber has a considerably higher variability of strength both within and between members. LÄS MER

  5. 20. Insurances against job loss and disability : Private and public interventions and their effects on job search and labor supply

    Författare :Josefine Andersson; Anders Forslund; Stefan Eriksson; Michael Rosholm; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Employment Security Agreements; job search assistance; job loss; notification; lump-sum severance grant; liquidity effect; disability insurance; financial incentives; continuous deduction; regression discontinuity design; propensity score matching; nearest neighbor matching; Economics; Nationalekonomi;

    Sammanfattning : Essay I: Employment Security Agreements, which are elements of Swedish collective agreements, offer a unique opportunity to study very early job search counselling of displaced workers. These agreements provide individual job search assistance to workers who are dismissed due to redundancy, often as early as during the period of notice. LÄS MER
