  1. 1. Genetic Characterisation of Human ABO Blood Group Variants with a Focus on Subgroups and Hybrid Alleles

    Författare :Bahram Hosseini Maaf; Avdelningen för hematologi och transfusionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; glycosyltransferase; SNP; computer modelling; ABO genotyping; Immunology; serology; hybrid; Blood group ABO; transplantation; subgroup; Immunologi; serologi; rare O allele;

    Sammanfattning : ABO is the most important blood group system in transfusion medicine and transplantation immunology. The ABO blood groups differ by the presence or absence of antigens on RBCs and antibodies in plasma. Accurate determination of ABO status is critical. Genomic typing can increase the precision of blood group determination in complicated cases, e. LÄS MER

  2. 2. Computational Aspects of Maass Waveforms

    Författare :Fredrik Strömberg; Dennis A. Hejhal; Andreas Strömbergsson; David Farmer; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Mathematical analysis; Maass waveform; Congruence subgroup; Noncongruence subgroup; Multiplier system; Theta multiplier system; Eta multiplier system; real weight; Hecke operator; Involution; Dirichlet character; Spectral Theory; Computation; Matematisk analys; Mathematical analysis; Analys; matematik; Mathematics;

    Sammanfattning : The topic of this thesis is computation of Mass waveforms, and we consider a number of different cases: Congruence subgroups of the modular group and Dirichlet characters (chapter 1); congruence subgroups and general multiplier systems and real weight (chapter 2); and noncongruence subgroups (chapter 3). In each case we first discuss the necessary theoretical background. LÄS MER

  3. 3. To Blend in or Stand out? - Hospital Social Workers' Jurisdictional Work in Sweden and Germany

    Författare :Manuela Sjöström; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; cross-national case study; health care; hospital social work; jurisdiction; profession; professional association; professional subgroup; subordination;

    Sammanfattning : This dissertation describes, analyses, and compares the means by which hospital social work associations in Sweden and Germany pursue their members’ professionalization through ‘jurisdictional work’. The time period covered by the research is 1989 through 2008. LÄS MER

  4. 4. On the Optimisation and Regulation of Clinical Trials

    Författare :Sebastian Jobjörnsson; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; decision theory; Bayesian statistics; optimal stopping.; clinical trials; subgroup analysis; drug regulation;

    Sammanfattning : The basic premise of this thesis is that Bayesian Decision Theory (BDT) can and should be used to solve clinical trial design problems. While the flexibility of the framework allows for accommodating a great variety of situations, it also requires an explicit consideration of the gains and costs associated with the trial. LÄS MER

  5. 5. Optimisation of Clinical Trials using Bayesian Decision Theory

    Författare :Sebastian Jobjörnsson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ; decision theory; drug regulation; Bayesian statistics; subgroup analysis; clinical trials; health economics; multiple testing; decision theory;

    Sammanfattning : A decision maker confronted with the task of designing a clinical trial has to consider a multitude of aspects. Large trials lead to more evidence,which in turn makes it less likely that harmful decisions are taken when deciding on future treatments for patients. LÄS MER
