  1. 16. Aqueous Solutions as seen through an Electron Spectrometer Surface Structure, Hydration Motifs and Ultrafast Charge Delocalization Dynamics

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Niklas Ottosson; Uppsala universitet.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Water; Aqueous solutions; Ions; Molecular Hydration; Electron dynamics; Atmospheric Chemistry; Hydrolysis; Acid-Base Chemistry; Interatomic Coulombic Decay; ICD; Liquid Micro-Jet; X-ray Photoelectron Spectroscopy; XPS; Auger Electron Spectroscopy; AES; MAX-lab; BESSY; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : In spite of their high abundance and importance, aqueous systems are enigmatic on the microscopic scale. In order to obtain information about their geometrical and electronic structure, simple aqueous solutions have been studied experimentally by photo- and Auger electron spectroscopy using the novel liquid micro-jet technique in conjunction with synchrotron radiation.

  2. 17. Risk from radionuclides: a frog's perspective Accumulation of 137Cs in a riparian wetland, radiation doses, and effects on frogs and toads after low-dose rate exposure

    University dissertation from Stockholm : Systemekologiska institutionen

    Author : Karolina Stark; Stockholms universitet.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dose model; mass balance budget; overbank sedimentation; amphibian; phantom; thermoluminescence chip; radiosensitivity; DNA damage; NATURAL SCIENCES Biology; NATURVETENSKAP Biologi;

    Abstract : Threats from man-made radionuclides include waste issues, increasing number of power plants, underground bomb testing, nuclear weapons, and “dirty bombs”. Until recently the ionizing radiation protection system focused on protecting humans with an implied protection of biota. READ MORE

  3. 18. Thermal Properties of Clusters and Molecules - Experiments on Evaporation, Thermionic Emission, and Radiative Cooling

    University dissertation from Göteborg : University of Gothenburg

    Author : Erika Sundén; Göteborgs universitet.; Gothenburg University.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; water clusters fullerenes unimolecular decay evaporation thermionic emission radiative decay cooling rates heat capacities;

    Abstract : This thesis presents experiments performed on clusters and molecules, where the three channels of unimolecular decay have been studied. Evaporation from protonated and negatively charged water cluster have yielded size dependent heat capacities, where the smallest sizes with fewer than $21$ molecules show a heat capacity similar to bulk ice whereas clusters with molecules between $21$ and $300$ have a heat capacity in between that of ice and liquid water.

  4. 19. Studies in Mortgage Pricing and Finance Theory

    University dissertation from Uppsala : Nationalekonomiska institutionen

    Author : Stefan Toll; Uppsala universitet.; [2004]
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; Mortgage pricing; Finance theory; Reverse mortgages; Optimal loan contracts; Credit risk; Nationalekonomi; SOCIAL SCIENCES Business and economics Economics; SAMHÄLLSVETENSKAP Ekonomi Nationalekonomi;

    Abstract : This thesis consists of three self-contained essays.Essay 1 examines the question of why reverse or participating mortgages have not been as much in demand as predicted. A theoretical framework is derived for evaluating the expected utility associated with a reverse or participating mortgage. READ MORE

  5. 20. mRNA degradation factors as regulators of the gene expression in Saccharomyces cerevisiae

    University dissertation from Umeå : Umeå University

    Author : Mridula Muppavarapu; Umeå universitet.; [2016]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mRNA decapping; mRNA degradation; Pat1; Edc3; Lsm4; Lsm1-7; P bodies; Dcp2; Transcription; Ribosome biogenesis; Exosome.; molekylärbiologi; Molecular Biology;

    Abstract : Messenger RNA degradation is crucial for the regulation of eukaryotic gene expression. It not only modulates the basal mRNA levels but also functions as a quality control system, thereby controlling the availability of mRNA for protein synthesis. READ MORE
