Adsorption sites in coadsorption systems determined by photoemission spectroscopy : K and CO coadsorbed on Rh(111)

The adsorption sites of coadsorbed K and CO on the Rh(111) surface have been determined using high-resolution core-level spectroscopy, low-energy electron diffraction and site-resolved photoelectron diffraction. For both a (2 × 2)-2CO-1K and a (2√3 × 2√3)-6CO-1K structure, we find that the CO molecules occupy threefold hollow sites and the K atoms on-top sites, contrary to the adsorption sites of

Förflyttning vid utrymning : en utvärdering av mätmetoder

Accurate measurement of people’s movement patterns during evacuation requires appropriate data collection methods. This study examines three different methods, namely cameras placed above the crowd, triangulation using two cameras and distance measurements with laser scanners. Experiments were performed both in the laboratory and the field in order to evaluate the different methods. The results su

Protein dynamics: aggregation and mechanical unfolding

The subject of this thesis is protein dynamics. Papers I--IV and VI study either of two different processes: mechanical unfolding and aggregation. Paper V presents a computationally efficient all-atom model for proteins, variants of which are used to perform Monte Carlo simulations in the other papers. Mechanical unfolding experiments probe properties of proteins at the single molecule level. The

Knowledge Representation and Planning Strategies for Batch Plant Operating Procedure Synthesis

Synthesis of operating procedures for batch plants involves systematic generation of step by step instructions which the operator can implement to manage the batch plant safely and optimally. This is a labor and knowledgeintensive task. It often takes weeks of effort by experts to prepare a clear and error free set of instructions even for a moderately complex plant. If this process is automated,

Adsorption of acetylene and hydrogen on Pd(111) : Formation of a well-ordered ethylidyne overlayer

The C2H2(+H)/Pd(111) system has been studied using high resolution core level spectroscopy and low energy electron diffraction (LEED). Two ordered phases were found when adsorbing C2H2 at 125 K, giving rise to a (2 × 2) and a (√3 × √3)R30° LEED pattern, respectively. When preadsorbing H at 110-150 K, the sticking probability of the C2H2 molecules is strongly reduced and only the (√3 × √3)R30° over

The YbNi interface studied with photoemission spectroscopy

The development of the ytterbium valence band region was followed with Synchrotron radiation induced Photoemission Spectroscopy (SPS) by interdiffusion of Yb into a Ni (110) single crystal in order to identify the valence conditions of Yb in the bulk and on the surface. During this process, also the width of the Ni L3VV Auger transition was investigated with X-ray induced Photoemission Spectroscop

Self-reported mindfulness mediates the relation between meditation experience and psychological well-being

A well established notion in Buddhist literature is that meditation practice improves the ability to be mindful in daily life which in turn promotes psychological wellbeing. In order to test this hypothesis the relations between meditation experience, five mindfulness facets and psychological well-being were studied in a sample consisting of Buddhist meditators, Western mindfulness meditators and

Societal services and traumatic spinal cord injury: A multifaced interaction

The licentiate thesis is based on three papers. The aim of the research is to elucidate and analyze how societal services in practice are made available (or not available) and are utilized (or not utilized) by a group of individuals with traumatic spinal cord injuries (SCI). The first article is an inventory of Swedish societal support and services that one can apply for after a traumatic SCI. Tw
