  2. 1. alpha-synuclein: amyloid fibrils and interactions with lipid membranes

    Author : Marija Dubackic; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; alpha-synuclein; model lipid membranes; amyloid fibrils; Parkinson s disease; Lewy bodies; SANS; SAXS;

    Abstract : The second most common neurodegenerative disease, Parkinson’s disease, is linked with an amyloid forming protein, alpha-synuclein. Hallmarks of Parkinson’s disease are progressive loss of dopaminergic neurons and accumulation of intraneuronal inclusions termed Lewy bodies. READ MORE

  4. 2. Cellular interactions of HAMLET and their role in cell death

    Author : Maria Trulsson; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; HAMLET; alpha-lactalbumin; cancer; cell death; ion channels; p38; cell detachment; alpha-actinin; endocytosis; macropinocytosis; c-Myc; glycolysis;

    Abstract : HAMLET is a protein-lipid complex that selectively kills tumor cells. In this thesis, we identified new mechanisms, whereby HAMLET initiates and executes tumor cell death. HAMLET targets several cellular compartments ranging from the plasma membrane to the nucleus. READ MORE

  5. 3. Robust Water Balance Modeling with Uncertain Discharge and Precipitation Data : Computational Geometry as a New Tool

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Alpha shape; Convex hull; Depth function; Discharge; Hydrological models; Honduras; Model calibration; Parameter-value estimation; Precipitation; Rating curve; Robust; Robustness; Uncertainty estimation; Water resources.; Alfaform; avbördningskurva; djupfunktion; Honduras; hydrologiska modeller; konvext hölje; modellkalibrering; nederbörd; osäkerhetsskattning; parametervärdesskattning; robust; robusthet; vattenföring; vattenresurser; Hydrology; Hydrologi;

    Abstract : Models are important tools for understanding the hydrological processes that govern water transport in the landscape and for prediction at times and places where no observations are available. The degree of trust placed on models, however, should not exceed the quality of the data they are fed with. READ MORE

  6. 4. Influence of Nuclear Structure on Decay Properties of Heavy Nuclei

    Author : Daniel Ward; Matematisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; alpha decay; hindrance factors; Skyrme-Hartree-Fock-Bogoliubov model; superheavy nuclei; fission yields; Brownian-shape motion; nuclear structure; nuclear level density; alpha decay; hindrance factors; Skyrme-Hartree-Fock-Bogoliubov model; superheavy nuclei; fission yields; Brownian-shape motion; nuclear structure; nuclear level density; Fysicumarkivet A:2017:Ward;

    Abstract : This dissertation deals with the effects of nuclear structure on the α-decay properties, and on the fission-yielddistributions from the decay of heavy nuclei. The nuclear-structure and decay properties of superheavynuclei is one of the central topics for investigation. READ MORE

  7. 5. Lyman-alpha radiative transfer in Star-forming galaxies

    Author : Florent Duval; Göran Östlin; Marc Dijkstra; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Astronomy; astronomi;

    Abstract : This thesis focuses on the intrinsically strongest spectral signature of star-forming galaxies: the Lyman alpha recombination line of the hydrogen atom (hereafter Lya). Located at the wavelength of 1215. READ MORE
