  2. 1. DESIREE: Instrumentation Developments and Hot Metal Cluster Decays

    Author : Emma K. Anderson; Henning Schmidt; Henrik Cederquist; Henning Zettergren; Oded Heber; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; DESIREE; microchannel plate; clusters; spontaneous decay; small metal cluster anions; silver; copper; gold; carbon dianions; fragmentation; vibrational autodetachment; DESIREE; mikrokanalplattor; kluster; spontana sönderfall; små metallklusteranjoner; silver; koppar; guld; kol di-anjoner; fragmentering; Physics; fysik;

    Abstract : This thesis presents instrumentation developments and measurements performed at the Double ElectroStatic Ion Ring ExpEriment, DESIREE, at Stockholm University. DESIREE operates at cryogenic temperatures ~13 K, with very low background pressures of ~10-14mbar, allowing the observation of stored ions to long times of tens of seconds and longer. READ MORE

  4. 2. Who cares? Fragmentation or integration of cancer care

    Author : Helena Ullgren; Per Fransson; Lena Sharp; Magnus Lindskog; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Health care utilization; end-of-life care; integrated care; palliative care; clinical decision-making; omvårdnadsforskning med medicinsk inriktning; Caring Sciences;

    Abstract : Background: New cancer treatments and increased accessibility of palliativecare have resulted in improved treatment outcomes. Coordination andcommunication between different health care professionals and providers mayimpact patient satisfaction and quality of care. READ MORE

  5. 3. New Proteomics Methods and Fundamental Aspects of Peptide Fragmentation

    Author : Mikhail Savitski; Roman Zubarev; Per Andren; David Fenyö; Uppsala universitet; []
    Keywords : Bioinformatics; Proteomics; Peptide fragmentation; Bioinformatik;

    Abstract : The combination of collision-activated dissociation, (CAD) and electron capture dissociation, (ECD) yielded a 125% increase in protein identification. The S-score was developed for measuring the information content in MS/MS spectra. This measure made it possible to single out good quality spectra that were not identified by a search engine.

  6. 4. Energy and material recovery from high-ash waste through pyrolysis

    Author : Katarzyna Jagodzińska; Weihong Yang; Pär Jönsson; Tobias Richards; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pyrolysis; torrefaction; landfill waste; shredder fines; hydrogen production; carbon nanotubes; circular economy; pyrolys; torrefiering; avfall från deponier; finfraktioner från fragmentering; vätgasproduktion; kolbaserade nanorör; cirkulär ekonomi; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : Undoubtedly, the past practices of profit maximisation by all means, which fuelled swift industrialisation and urbanisation, left behind a legacy of non-sanitary old landfills polluting the environment. These, together with active landfills supplied with tremendous streams of waste produced annually, are a loose cannon calling for action. READ MORE

  7. 5. Nuclear motion in molecular ions studied with synchrotron radiation and multicoincidence momentum imaging spectrometry

    Author : Joakim Laksman; Synkrotronljusfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecule; synchrotron;

    Abstract : A momentum imaging spectrometer optimized for photoionization experiments with synchrotron radiation was built in 2008. The spectrometer is equipped with an electrostatic lens, that focuses the charged dissociation products on to a position-sensitive multi-hit delay line anode. READ MORE
