  2. 6. Weld Cracking in Precipitation Hardening Ni-based Superalloys

    Author : Fabian Hanning; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; welding; post weld heat treatment; weldability; Nickel based superalloys; strain age cracking; weld cracking;

    Abstract : Manufacturing of hot structural components for aero engines requires the materials being used to be weldable. The high demands on strength and temperature resistance make nickel based superalloys the material of choice for this application. READ MORE

  4. 7. Problems in Number Theory related to Mathematical Physics

    Author : Rikard Olofsson; Pär Kurlberg; Nalini Anantharaman; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; number theory; mathetical physics; local zeta functions; cat maps; Beurling primes; MATHEMATICS; MATEMATIK;

    Abstract : This thesis consists of an introduction and four papers. All four papers are devoted to problems in Number Theory. In Paper I, a special class of local ζ-functions is studied. The main theorem states that the functions have all zeros on the line Re(s)=1/2. READ MORE

  5. 8. A study of b-secretase cleaved Alzheimer amyloid precursor protein

    Author : Kristina Sennvik; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Alzheimer's disease (AD) is characterized by the degeneration and loss of neurons, intracellular neurofibrillary tangles and the accumulation of extracellular senile plaques consisting mainly of beta-amyloid (A-beta). A-beta is generated from the amyloid precursor protein (APP) through sequential cleavage by proteases P- and gamma-secretase. READ MORE

  6. 9. Paracrine regulation of Sertoli cell proliferation

    Author : Cecilia Petersen; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Testis; Sertoli cell; proliferation; growth factor; proinflammatory cytokine;

    Abstract : The Sertoli cell is a highly differentiated somatic cell in the seminiferous epithelium of the testis. This cell is of prime importance for both testicular development and spermatogenesis. READ MORE

  7. 10. Immunotherapy in cancer and HIV

    Author : Susanne Johansson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Immunotherapy; Cancer; HIV; DNA-vaccine; Conjugated mAb; NK-cells;

    Abstract : Two major threats to human health are cancer and human immunodeficiency virus (HIV) infection. In both cases, a feature of progress of the disease is a defective immune function. Immunological mechanisms have evolved whereby transformed cells and HIV-1 infected cells avoid recognition and elimination by the immune system. READ MORE
