  1. 1. Combinatorics and topology related to involutions in Coxeter groups

    Författare :Mikael Hansson; Axel Hultman; Jan Snellman; Nathan Reading; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This dissertation consists of three papers in combinatorial Coxeter group theory.A Coxeter group is a group W generated by a set S, where all relations can be derived from the relations s2 = e for all s ? S, and (ss′)m(s,s′) = e for some pairs of generators s ≠ s′ in S, where e ? W is the identity element and m(s, s′) is an integer satisfying that m(s, s′) = m(s′, s) ≥ 2. LÄS MER

  3. 2. Generalised Ramsey numbers and Bruhat order on involutions

    Författare :Mikael Hansson; Axel Hultman; Jan Snellman; Jonas Sjöstrand; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis consists of two papers within two different areas of  combinatorics.Ramsey theory is a classic topic in graph theory, and Paper A deals with two of its most fundamental problems: to compute Ramsey numbers and to characterise critical graphs. More precisely, we study generalised Ramsey numbers for two sets Γ1 and Γ2 of cycles. LÄS MER

  4. 3. Kollektivavtalsrätten : en rättsvetenskaplig berättelse

    Författare :Mikael Hansson; Jonas Malmberg; Mia Rönnmar; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Kollektivavtal; arbetsrätt; rättsvetenskap; narratologi; Labour law; Arbetsrätt; Civil Law; Civilrätt;

    Sammanfattning : The collective agreement is considered to be the single most important method of regulating the labour market in Sweden. Its importance is emphasised by the fact that there is no legislation concerning wages, and that labour-market legislation often can be derogated from by collective agreements (quasi-mandatory statutes).

  7. 5. Structural Determination of Drug Metabolites from Doping Classed Compounds Using Mass Spectrometry

    Författare :Annelie Hansson; Mikael Hedeland; Ulf Bondesson; Peter Hemmersbach; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mass spectrometry; UHPLC-MS MS; doping control; Cunninghamella elegans; selective androgen receptor modulator; SARM; andarine; ostarine; LGD-4033; roxadustat; HIF stabilizer; Analytical Pharmaceutical Chemistry; Analytisk farmaceutisk kemi;

    Sammanfattning : Doping control in equine sports is important for a fair competition, but also to ensure the integrity of the betting system, as well as for animal welfare reasons. To detect the use of illicit compounds, screening for the parent compound is common. However, by using a metabolite as the analytical target instead, the detection time can be prolonged. LÄS MER
