  1. 1. Structural Studies of Large dsDNA Viruses using Single Particle Methods

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Hemanth Kumar Narayana Reddy; Uppsala universitet.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; PR772; phage; PRD1; Bacteriophage; coliphage; Melbournevirus; Cedratvirus; lurbo; Pithovirus; CryoEM; Single particle imaging; Coherent; Diffractive; Imaging; Soft X-ray; Microscopy; Microscope; GDVN; High resolution; XFEL; aerosol; Injection; electrospray; gas dynamic virtual nozzle; CDI; CXI; FEL; Chemistry with specialization in Biophysics; Kemi med inriktning mot biofysik;

    Abstract : Structural studies of large biological assemblies pose a unique problem due to their size, complexity and heterogeneity. Conventional methods like x-ray crystallography, NMR, etc. are limited in their ability to address these issues. To overcome some of these limitations, single particle methods were used. READ MORE

  2. 2. Coherent Diffractive Imaging with X-ray Lasers

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Max Felix Hantke; Uppsala universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; coherent diffractive X-ray imaging; lensless imaging; coherent X-ray diffractive imaging; flash diffractive imaging; single particle imaging; aerosol injection; electrospray injection; substrate-free sample delivery; carboxysome; phase retrieval; X-ray diffraction software; X-ray free-electron laser; XFEL; FEL; CXI; CDI; CXDI; FXI;

    Abstract : The newly emerging technology of X-ray free-electron lasers (XFELs) has the potential to revolutionise molecular imaging. XFELs generate very intense X-ray pulses and predictions suggest that they may be used for structure determination to atomic resolution even for single molecules. READ MORE

  3. 3. Fundamental Studies on Direct Injection Nebulisers for Sample Introduction in ICP Spectrometry Aerosol Properties, ICP Characteristics and Analytical Performance

    University dissertation from Umeå : Kemi

    Author : Daniel Goitom Asfaha; Umeå universitet.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ICP; ICP-MS; ICP-OES; sample introduction; DIHEN; Vulkan DIN; non-spectral interferences; noise power spectra; analytical precision; plasma diagnostic parameters; particle dynamic analysis PDA ; NATURAL SCIENCES Chemistry Analytical chemistry; NATURVETENSKAP Kemi Analytisk kemi;

    Abstract : The performance of different types of nebulisers: Vulkan direct injection nebuliser (Vulkan DIN), direct injection high efficiency nebuliser (DIHEN), microconcentric nebuliser coupled to cyclonic or double pass spray chamber (MCN-C or MCN-DP, respectively) was investigated and compared when used for sample introduction to ICP-MS or ICP-OES. With ICP-OES, in axial viewing mode, intensity distributions across the radius of the plasma (radial intensity profiles) were determined for different spectral lines with Esum 1. READ MORE

  4. 4. Algorithms for Coherent Diffractive Imaging with X-ray Lasers

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Benedikt J. Daurer; Uppsala universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; X-ray lasers; coherent diffractive imaging; algorithms; lensless imaging; flash diffractive imaging; flash X-ray imaging; aerosol injection; FEL; XFEL; CXI; CDI; FXI; Physics with specialization in Biophysics; Fysik med inriktning mot biofysik;

    Abstract : Coherent diffractive imaging (CDI) has become a very popular technique over the past two decades. CDI is a "lensless" imaging method which replaces the objective lens of a conventional microscope by a computational image reconstruction procedure. READ MORE

  5. 5. Solute exhange across the alveolo-capillary barrier

    University dissertation from Clinical Physiology

    Author : Kristina Nilsson; Lund University.; Lunds universitet.; [1997]
