  1. 1. Born Small for Gestational Age : Beyond Size at Birth

    Författare :Linda Lindström; Anna-Karin Wikström; Eva Bergman; Maria Lundgren; Kjell Å Salvesen; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Small for Gestational Age; SGA; Epidemiology; Pregnancy; Postnatal growth; Intrauterine growth restriction; Chronic hypertension; School performance; Obstetrik och gynekologi; Obstetrics and Gynaecology;

    Sammanfattning : Children born small for gestational age (SGA) run increased risk of perinatal morbidity and mortality, but also of long-term health impairment. Risks on long term may vary depending on postnatal growth patterns. LÄS MER

    Sammanfattning : The world-wide intensification of agriculture has led to a decline in species richness due to land use change, isolation, and fragmentation of natural and semi-natural habitats in agricultural and forestry landscapes. As a consequence, there is a current landscape management focus on the importance of green infrastructure to mitigate biodiversity decline and preserve ecosystem functions e. LÄS MER

  4. 3. Innovative Behaviour of Small Firms : Essays on Small Firms' Internationalisation and Use of Online Channels

    Författare :Vladimir Vanyushyn; Håkan Boter; Maria Bengtsson; Robert Blackburn; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Innovation; small and medium-sized enterprises; Internet; marketing; internationalisation; Sweden; Finland; Innovation; små och medelstora företag; onlinekanaler; Internet; marknadsföring; internationalisering; Sverige; Finland; Business studies; Företagsekonomi; företagsekonomi; Business Studies;

    Sammanfattning : The spread of information technology and the dissolution of international borders have had a significant impact on the challenges and opportunities faced by today's small and medium-sized enterprises (SMEs). Innovative behaviour on the part of SMEs is a prerequisite for a successful transformation of the opportunities offered by these structural changes into growth and profitability. LÄS MER

  5. 4. Why and how brain size evolves : Sociality, predation and allometry

    Författare :Wouter van der Bijl; Niclas Kolm; Joah Madden; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; brain size; brain size evolution; encephalization; predation; predator inspection; sociality; animal contest; constraint; etologi; Ethology;

    Sammanfattning : The evolution of the vertebrate brain has remained a topic of intense interest from biologists over many decades. Evolutionary biologists have seen it as an intriguing example of how the size and structure of a trait evolves across large phylogenies and under body size constraints, with both large shifts in deep evolutionary time and continuous smaller scale adaptation.

  7. 5. Modelling and simulation of plastic deformation on small scales : interface conditions and size effects of thin films

    Författare :Per Fredriksson; Peter Gudmundson; Christian Niordson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strain gradient plasticity; Size effects; Thin films; Interface; Finite element method; Dislocations; Constitutive behaviour; Hardening behaviour; Indentation; Contact mechanics; Metal matrix composites; Engineering mechanics; Teknisk mekanik;

    Sammanfattning : Contrary to elastic deformation, plastic deformation of crystalline materials, such as metals, is size-dependent. Most commonly, this phenomenon is present but unnoticed, such as the effect of microstructural length scales. LÄS MER
