This thesis deals with the development and application of laser-based techniques, for gas phasecharacterization/gas imaging in heterogeneous catalysis. Two techniques are presented: planar laser-induced fluorescence (PLIF) and degenerate four wave mixing (DFWM).This thesis is mainly focused on PLIF for the visualization of CO2 and CO in the vicinity of a catalyst during CO oxidation reaction at se
Xylan has a main chain consisting of β-1,4-linked xylose residues with diverse substituents. Endoxylanases cleave the xylan chain at cleavage sites determined by the substitution pattern and thus give different oligosaccharide product patterns. Most known endoxylanases belong to glycoside hydrolase (GH) families 10 and 11. These enzymes work well on unsubstituted xylan but accept substituents in c
A high resolution capillary electrophoresis method is developed for monitoring enzymatic reactions catalyzed by glycosyltransferases. Under inverted electroosmotic flow conditions at pH 2.5, the method quantifies UDP, UDP-Gal, UDP-Glc, and UDP-GlcNAc in the range of 10 to 150 μM. Enzyme activity of α-1,3-galactosyltransferase was determined by monitoring the formation of UDP subproduct formed in t
A search for the decay of the Standard Model Higgs boson into a bb¯ pair when produced in association with a W or Z boson is performed with the ATLAS detector. The data, corresponding to an integrated luminosity of 79.8fb−1 were collected in proton–proton collisions during Run 2 of the Large Hadron Collider at a centre-of-mass energy of 13TeV. For a Higgs boson mass of 125GeV, an excess of events
Searches for the exclusive decays of the Higgs and Z bosons into a J/ψ, ψ(2S), or ϒ(nS) (n=1,2,3) meson and a photon are performed with a pp collision data sample corresponding to an integrated luminosity of 36.1fb−1 collected at s=13TeV with the ATLAS detector at the CERN Large Hadron Collider. No significant excess of events is observed above the expected backgrounds, and 95% confidence-level up
One strategy to achieve coordination of care for older people with complex care needs is the establishment of shared care plans. The aim of this study was to explore the process of establishing a shared care plan from the perspective of elderly people and their next of kin. Data were collected via 12 semi-structured interviews with 12 older persons targeted in joint care planning and 11 next of ki
The global nature of businesses has increased the geographical dispersion of operations and has made the location decision an important strategic perspective for manufacturing firms. The consensus view is that three major plant location factors must be kept in mind: (1) access to low-cost manufacturing, (2) proximity to market, and (3) access to development competences. Two options for changing th
The present study investigates the significance of potential slip in the bracings of simply supported slender timber members. Three bracing configurations are considered. The first case is that of a timber beam braced at one point at mid-span, the second one braced at two points and the third one braced at three points. Possible slip in the bracing members can for example be due to joint deformati
The spatiotemporal stability of wild organisms, such as flower-visiting insects, is critical to guarantee high levels of biodiversity in agroecosystems. Whereas the proportion of semi-natural habitats in the landscapes has been shown to stabilize the species richness of flower visitors, the effect of farming intensity has not yet been studied. In this study, we compared the temporal and spatial st
This paper describes how MAX IV, the first Multi-Bend Achromat (MBA) Synchrotron Radiation Light Source, was developed and realized. It describes the process of defining the scientific case and the development of the accelerator concepts. This was a highly interactive and intense optimization process, which went on during a long time with tight communication between the laboratory and the various
We revise three common models accounting for water exchange in pulsed-gradient spin-echo measurements: a bi-exponential model with time-dependent water fractions, the Kärger model, and a modified Kärger model designed for restricted diffusion, e.g. inside cells. The three models are compared and applied to experimental data from yeast cell suspensions. The Kärger model and the modified Kärger mode
Sixty percent of stroke volume (SV) is generated by atrioventricular plane displacement (AVPD) in a healthy left ventricle (LV). The aims were to determine the effect of ST-elevation myocardial infarction (STEMI) on AVPD and contribution of AVPD to SV and to study the relationship between AVPD and infarct size (IS) and location. Patients from CHILL-MI and MITOCARE studies with cardiovascular magne
An experimental campaign has been carried out with the aim of providing an insight into the fracture processes occurring during the cutting of different types of polymers, with features ranging from typically brittle to soft hyperelastic behaviour. The steady state of cutting is investigated using a sharp thin blade, and tracking the insertion force versus the penetration displacement. For soft, h
A frequent belief is that the rise of so-called “gig work” has led to the displacement of workers in a wide range of traditional jobs. This paper examines the impacts of the flagship of the gig economy—Uber—on workers employed in conventional taxi services. Our analysis exploits newly collected data on the staggered rollout of Uber across metropolitan areas in the United States and a difference-in
Objective: We aimed to explore the effect of occupation on familial risk of pleural mesothelioma in a nationwide cohort study design. Method: The nationwide Swedish Family-Cancer Database includes all Swedes born after 1931 and their biological parents, totalling 16.1 million individuals with about 2.3 million cancer patients. Hazards ratios (HRs) were calculated adjusting for age, sex and region
Introduction: The relationship between left ventricular (LV) ejection fraction (EF) and LV myocardial scar can identify potentially reversible causes of LV dysfunction. Left bundle branch block (LBBB) alters the electrical and mechanical activation of the LV. We hypothesized that the relationship between LVEF and scar extent is different in LBBB compared to controls. Methods: We compared the relat
Background: It remains unknown if bivalirudin compared to heparin confers any additional inhibition of platelet and coagulation activation during primary percutaneous coronary intervention (PPCI) after pretreatment with ticagrelor. Methods: In this substudy of VALIDATE-SWEDEHEART trial, 103 patients pretreated with ticagrelor were randomized before PPCI to heparin or bivalirudin. Blood samples wer
