  2. 1. Renewal and Heritage : The Quest for Authenticity in Hasan Hanafi's Islamic Ideology

    Author : Susanne Olsson; David Westerlund; Eva Evers Rosander; Leif Stenberg; Uppsala universitet; []
    Keywords : HUMANIORA; HUMANITIES; Islamologi; authenticity; continuity; Establishment Islam; globalisation; heritage; Islamism; Occidentalism; renewal; sacred authority; asalah; ijtihad; tawhid; turath; Islamologi; Islamology; Islamologi; History Of Religions; religionshistoria;

    Abstract : This study presents and analyses a contemporary interpretation of Islam by the Egyptian thinker Hasan Hanafi. His ideas are analysed in a perspective of the history of ideas where both Islamic and Western influences are taken into consideration. READ MORE

  4. 2. Ruin probabilities and first passage times for self-similar processes

    Author : Zbigniew Michna; Matematisk statistik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Simulation of Ruin Probability; Monte Carlo Method; Skorokhod Topology; Weak Convergence; Rice s Formula; Fluid Model; Risk Model; Scaled Brownian Motion; Long Range Dependence; Fractional Brownian Motion; Renewal Process; Levy Motion; Stable Process; Self-Similar Process; Gaussian Process; Ruin Probability; First Passage Time; Exponential Bound; Picands Constant.; Mathematics; Matematik;

    Abstract : This thesis investigates ruin probabilities and first passage times for self-similar processes. We propose self-similar processes as a risk model with claims appearing in good and bad periods. Then, in particular, we get the fractional Brownian motion with drift as a limit risk process.

  5. 3. Molecular and cellular analysis of Lhx2 function in hematopoietic stem cells

    Author : Karin Richter; Leif Carlsson; Andrew Elefanty; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hematopoietic stem cells; Lhx2; cell lines; self renewal; SCF; IL-6; chronic myeloproliferative disorder; global gene expression analysis; Molecular biology; Molekylärbiologi;

    Abstract : The formation of blood, hematopoiesis, is a dynamic process originating from a small number of hematopoietic stem cells (HSCs). To sustain hematopoiesis throughout life HSCs have the unique capacity to differentiate into all mature hematopoietic lineages as well as generating more HSCs by a mechanism referred to as self-renewal.

  6. 4. Identification and Characterization of Stem Cells in Preleukemia and Leukemia

    Author : Lars Nilsson; Stamcellscentrum (SCC); []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Haematology; extracellulära vätskor; Hematologi; Philadelphia chromosome; acute lymphoblastic leukemia; polycytemia vera; 5q- syndrome; myelodysplastic syndromes; self-renewal; preleukemia; Hematopoietic stem cells; leukemic stem cells; extracellular fluids;

    Abstract : Hematopoietic stem cells (HSCs) are responsible for the daily and life long production of large numbers of mature blood cells through highly regulated self-renewal and multilineage capabilities. Leukemias on the other hand, are characterized by a clonal, dysregulated, lineage skewed proliferation and impaired differentiation as the result of multiple accumulated genetic events. READ MORE

  7. 5. Live and Let Die : Critical regulation of survival in normal and malignant hematopoietic stem and progenitor cells

    Author : Pernilla Eliasson; Jan-Ingvar Jönsson; Mikael Sigvardsson; Urban Gullberg; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hematopoietic stem cells; hypoxia; self-renewal; survival; acute myeloid leukemia; FLT3; Cell and molecular biology; Cell- och molekylärbiologi; Haematology; Hematologi;

    Abstract : The hematopoietic stem cell (HSC) is characterized by its ability to self-renew and produce all mature blood cells throughout the life of an organism. This is tightly regulated to maintain a balance between survival, proliferation, and differentiation. READ MORE
