  1. 1. Bacterial use of allochthonous organic carbon for respiration and growth in boreal freshwater systems

    Författare :Martin Berggren; Mats Jansson; Michael L. Pace; Umeå universitet; []
    Nyckelord :lakes; streams; boreal; bacterial respiration; bacterial production; bacterial growth efficiency; allochthonous organic carbon; low molecular weight compounds; naturgeografi; Physical Geography;

    Sammanfattning : Aquatic systems worldwide receive large amounts of organic carbon from terrestrial sources. This ‘allochthonous’ organic carbon (AlloOC) affects critical physical and chemical properties of freshwater ecosystems, with consequences for food web structures and exchange of greenhouse gases with the atmosphere.

  3. 2. Verkstadsindustrins tjänstefiering : en explorativ resa i det nya affärslandskapet

    Författare :Martin Fransson; Per Norling; Christian Berggren; Karlstads universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Business studies; Företagsekonomi; Business Administration; Företagsekonomi;

    Sammanfattning : I läroböcker och managementlitteratur hävdas att industrins erbjudanden får ett allt större tjänsteinnehåll. Kunskapen om hur denna ”tjänstefiering” tar sig uttryck är emellertid begränsad. LÄS MER

  4. 3. The impact of motivation and person-job fit on employee turnover among Swedish real estate brokers: A mixed method approach

    Författare :Martin Ahlenius; Björn Berggren; Jonas Kågström; Lars-Johan Åge; Samuel Azasu; KTH; []

    Sammanfattning : Residential real estate is a vital part of the economy, and homes are important for individuals for both financial and emotional reasons. Residential homes change owners for numerous reasons, and there is a need for these transactions to be secure and efficient from both the economic and individual perspective. LÄS MER

  5. 4. Population-based studies in Myelodysplastic syndromes : Prognostic scores, socioeconomic status, and therapy-related disease

    Författare :Daniel Moreno Berggren; Elisabeth Ejerblad; Sören Lehmann; Martin Jädersten; David Bowen; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Myelodysplastic syndromes; Chronic myelomonocytic leukaemia; Prognostication; Comorbidity; Therapy-related disease; Real-world data; Population-based studies; Medicinsk vetenskap; Medical Science;

    Sammanfattning : The aim of this thesis was to expand the epidemiological knowledge of the haematological malignancy MDS and the related condition chronic myelomonocytic leukaemia (CMML). Using nationwide registers, the papers in this thesis address aspects of prognostication, comorbidity, socioeconomic status, and therapy-related disease, using a population-based approach. LÄS MER

  7. 5. Adjoint-based aerodynamic shape optimization

    Författare :Olivier Amoignon; Martin Berggren; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Numerical Analysis; Numerisk analys;

    Sammanfattning : An adjoint system of the Euler equations of gas dynamics is derived in order to solve aerodynamic shape optimization problems with gradient-based methods. The derivation is based on the fully discrete flow model and involves differentiation and transposition of the system of equations obtained by an unstructured and node-centered finite-volume discretization.
