  1. 1. The Dirac Equation: Numerical and Asymptotic Analysis

    Författare :Hasan Almanasreh; Göteborgs universitet.; Gothenburg University.; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dirac operator; eigenvalue problem; finite element method; spurious eigenvalues; Petrov-Galerkin; cubic Hermite basis functions; stability parameter; meshfree method; $hp$-cloud; intrinsic enrichment; G-convergence; $ Gamma$-convergence; scattering theory; identification; wave operator; stationary approach; meshfree method; $hp$-cloud; stability parameter; cubic Hermite basis functions; scattering theory; intrinsic enrichment; identification; spurious eigenvalues; wave operator; finite element method; $ Gamma$-convergence; eigenvalue problem; stationary approach; Petrov-Galerkin; G-convergence;

    Sammanfattning : The thesis consists of three parts, although each part belongs to a specific subject area in mathematics, they are considered as subfields of the perturbation theory. The main objective of the presented work is the study of the Dirac operator; the first part concerns the treatment of the spurious eigenvalues in the computation of the discrete spectrum. LÄS MER

    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; aspen; foliar condensed tannins; genetic variability; anthropogenic nitrogen enrichment; plant growth; plant defense; litter decomposition; Populus tremula; asp; kondenserade tanniner; genetisk variabilitet; antropogent kväve; tillväxt; växtförsvar; förna nedbrytning; Populus tremula; Environmental Science; miljövetenskap; ekologisk botanik; Ecological Botany; Entomology; entomologi; Physiological Botany; fysiologisk botanik; Population Biology; populationsbiologi;

    Sammanfattning : Boreal forests are often strongly nitrogen (N) limited. However, human activities are leading to increased N inputs into these ecosystems, through atmospheric N deposition and forest fertilization. LÄS MER

  3. 3. Intrinsic and extrinsic mechanisms for B-cell lymphoma development and progression studied by global gene expression profiling

    Detta är en avhandling från Stockholm : Karolinska Institutet, Dept of Laboratory Medicine

    Författare :Gustav Arvidsson; Karolinska Institutet.; Karolinska Institutet.; [2019]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Mantle cell lymphoma (MCL) is a rare hematopoietic malignancy characterized by frequent relapses and poor survival, partly due to minimal residual disease, whereby a subset of malignant cells, harbored in protective niches, survive treatment. In vitro and ex vivo experiments have shown that MCL cells can be rescued from apoptosis through interactions with non- malignant cells such as stromal cells. LÄS MER

  4. 4. Proteomics-informed analysis of drug disposition in the human liver and small intestine

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Christine Wegler; Per Artursson; Pär Matsson; Tommy B Andersson; Manthena Varma; [2019]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; proteomics; protein concentration; drug disposition; drug transport; drug metabolism; human small intestine; human liver; human hepatocytes; human liver microsomes; inter-individual variability; drug clearance; obesity; prediction model; Farmaceutisk vetenskap; Pharmaceutical Science;

    Sammanfattning : Orally administered drugs are absorbed in the intestine and generally metabolized in the liver. Therefore, understanding factors determining drug distribution and elimination in these tissues is important. LÄS MER

  5. 5. Resolving developing neuronal lineages in the ventral midbrain

    Detta är en avhandling från Stockholm : Karolinska Institutet, Dept of Cell and Molecular Biology

    Författare :Nigel Kee; Karolinska Institutet.; Karolinska Institutet.; [2017]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The numerous cells and cell types of our bodies originate from a fertilised egg. Through the study of the developing embryo, we have come to understand much about how different cells in different tissues arise from this single cell, and how they are related to one another within an expansive family tree.
