    Sammanfattning : Neurodegenerative disorders include a full spectrum of diagnoses, including dementias and other neuronal diseases, characterised by degradation of neurons in the brain occurring along with disease progression. Amongst the dementias, the most prevalent are Alzheimer’s (AD) and Parkinson’s disease (PD) that affect millions of people worldwide. LÄS MER

  7. 5. Aspects of trade credit

    Författare :Stefan Ingves; Handelshögskolan i Stockholm; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : This dissertation presents various aspects of how and why firms use trade credit. This is done by using several different models that make it possible to concentrate on one, or a few, aspects at a time. The analysis is carried out with the help of tools and methods provided by ordinary microeconomic theory. LÄS MER
