  2. 1. Formation of Block Copolymer and Surfactant Vesicles

    Author : Karin Bryskhe; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polymerteknik; Fysikalisk kemi; biopolymers; Polymer technology; nanoparticles; Lipid; triblock copolymer; surfactants; Nonionic; Vesicles; Formation; Physical chemistry;

    Abstract : In this thesis temperature induced vesicle formation in both a block copolymer system and nonionic surfactant system have been investigated. The block copolymer is a triblock copolymer of poly(ethylene oxide) (PEO) and poly(propylene oxide) (PPO), PEO-PPO-PEO, with the average molecular composition of EO5PO68EO5 and the commercial trade name Pluronic L121 (papers I, II).

  4. 2. Characterization of the inner nuclear membrane protein Samp1, during interphase and mitosis

    Author : Veronica J. Larsson; Einar Hallberg; Katharine S. Ullman; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Samp1; LINC complex; nuclear lamina; MCLIP; nuclear envelope; spindle assembly; spindle stability; k-fiber; gamma tubulin; Aurora B; Haus6; Augmin; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Abstract : The nucleus, a hallmark in eukaryotic cells, contains the genome separating it from molecules in the cytoplasm. The nucleus is surrounded by a nuclear envelope consisting of two concentric membranes, the outer nuclear membrane and the inner nuclear membrane, the nuclear lamina and nuclear pore complexes.

  5. 3. 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

  6. 4. Formation, partitioning and interactions of organic iodides under severe nuclear accident conditions

    Author : Sabrina Tietze; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Epoxy paint; Methyl iodide; Iodine source term; Organic iodides; Severe nuclear accidents;

    Abstract : During severe nuclear reactor accidents such as Chernobyl or Fukushima large amounts of radioactive iodine can be released in form of inorganic and organic iodine species into the environment. Volatile radioactive iodine species are harmful to human health when inhaled. READ MORE

  7. 5. Molecular gas in the galaxy M83 : Its distribution, kinematics, and relation to star formation

    Author : Andreas Andersson Lundgren; Hans Olofsson; John Whiteoak; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular gas; Galaxies; Galaxies individual: M83; Star formation; Galactic dynamics; Astronomy and astrophysics; Astronomi och astrofysik;

    Abstract : The barred spiral galaxy M83 (NGC5236) has been observed in the 12CO J=1–0 and J=2–1 millimetre lines with the Swedish-ESO Submillimetre Telescope (SEST). The sizes of the CO maps are 100×100, and they cover the entire optical disk. The CO emission is strongly peaked toward the nucleus. READ MORE
