Catalytic incineration is one of the methods to reduce the emissions of CO and VOCs. Low operation temperature and low catalyst cost are essential parameters for catalytic incinerators. Pt/Al2O3 catalysts are frequently used today, but the cheaper metal oxide catalysts can be very competitive if comparable overall activity is obtained. This thesis concerns how it is possible to decrease the operat
Acoustic fatigue can occur in structural elements of an aircraft exposed to very high sound pressures. To deal with acoustic fatigue, mainly empirical methods have been applied and often late in the design phase. Current design guidelines have several limitations. First, they do not say anything about the load intensities. The load levels can be determined either experimentally or numerically. Exp
To our knowledge, this is the first prospective study using validated questionnaires to assess patient-relevant outcomes after arthroscopic partial meniscectomy. Data from the Knee Injury and Osteoarthritis Outcome Score (KOOS), the SF-36 Medical Outcomes Study Short-Form Health Survey, and the Lysholm Knee Scoring Scale were available for 74 consecutive patients (50 males, 24 females; mean age, 4
Radiotherapy (RT) datasets can suffer from variations in annotation of organ at risk (OAR) and target structures. Annotation standards exist, but their description for prostate targets is limited. This restricts the use of such data for supervised machine learning purposes as it requires properly annotated data. The aim of this work was to develop a modality independent deep learning (DL) model fo
BACKGROUND: People with mental illness may have difficulties related to work and employment, especially if they experience additional difficult life situations. OBJECTIVE: To explore how subgroups with mental illness and additional adversities perceived their situation with respect to work and employment prospects. METHODS: Three subgroups were included, exposed to an additional difficult life sit
OBJECTIVE: To explore the prevalence and reproducibility of paradoxically increased nasal airway resistance after decongestion of the nasal mucosa as well as to identify patient-related factors associated with it.DESIGN: Retrospective analysis of all rhinomanometric measurements carried out at one ENT department in Sweden in the time between 1990 and 2010. In the baseline material, 207 of 4435 pat
In 2015, LIBER commissioned the “Working group on Research and Education”. The goal was to collect best practices in library support to both education and research, in part by examining user survey data. As a first step the group started a European LibQUAL consortium, which was evaluated in 2016. As a second step, a survey sent to all 301 European LIBER university libraries asking questions pertai
Zone plates are diffractive optics commonly used in X-ray microscopes. Here, we present a wet-chemical approach for fabricating high aspect ratio Pd/Si zone plate optics aimed at the hard X-ray regime. A Si zone plate mold is fabricated via metal-assisted chemical etching (MACE) and further metalized with Pd via electroless deposition (ELD). MACE results in vertical Si zones with high aspect ratio
Visual abilities of the honey bee have been studied for more than 100 years, recently revealing unexpectedly sophisticated cognitive skills rivalling those of vertebrates. However, the physiological limits of the honey bee eye have been largely unaddressed and only studied in an unnatural, dark state. Using a bright display and intracellular recordings, we here systematically investigated the angu
We present a fabrication scheme of contacting arrays of vertically standing nanowires (NW) for LEDs (Duan et al. Nature 409:66–69, 2001), photodetectors (Wang et al. Science (NY) 293:1455–1457, 2001) or solar cell applications (Wallentin et al. Science (NY) 339:1057–1060, 2013). Samples were prepared by depositing Au films using nano-imprint lithography (Ma rtensson et al. Nano Lett 4:699–702, 200
The Edictum Diocletiani et collegarum: The so-called Edict of Maximum Prices was issued in AD 301 as part of a comprehensive administrative and financial reform released in the reign of the Roman emperor Diocletian. Diocletian came to power in AD 284 after a period in Roman history traditionally understood as a time of ‘crisis’, produced by a series of inter-related factors: a frequent turnover of
Roma and Travellers (”resande”) have been present in Sweden for centuries. In the 19th and early 20th centuries, rural municipalities (kommuner) often adopted policies aimed to expel them from or to prevent them from entering the municipality. This is well established by previous research. What is less known is that another kind of territorial exclusion existed as well: that of collective violence
ABSTRACTAIM: The overall aim of this longitudinal PhD project was to gain increased knowledge about factors associated with fear of falling (FOF) falls and near falls, as well as to contribute to improved clinical fall prediction for peoplewith mild Parkinson’s disease (PD).METHODS: People diagnosed with PD and receiving care at the university hospital outpatient neurology clinic were assessed dur
Pile heat exchangers are fast emerging as a potentially viable alternative to the more prevalent borehole heat exchangers for the provision of space heating and cooling. In the last decade or so, the use of geothermal piles has increased sharply in many countries including Belgium, China, Japan, Switzerland, the Netherlands, United Kingdom, and United States, among others. In Sweden, however, inte
Institutions for prevention and resolution of industrial conflicts were introduced all over the world in the early twentieth century. We use a new dataset of geocoded strikes and lockouts to analyze the impact of mediation on conflict outcomes in Sweden for the period 1907–1927. Causality is identified by using the distance from the mediator’s place of residence to the conflict as an instrument. D
The PHENIX experiment at the Relativistic Heavy Ion Collider has measured the differential cross section of φ(1020)-meson production at forward rapidity in p+p collisions at s=510 GeV via the dimuon decay channel. The partial cross section in the rapidity and pT ranges 1.2
In this paper we describe field investigations of leachate recirculation at a bioreactor landfill using geoelectrical imagining technique (i.e., electrical resistivity) combined with a tracer test. The use of geoelectrical imagining techniques is an established practice for environmental investigations and monitoring of various landfill processes and in recent years also the bioreactor landfill co
Background: As the treatment arsenal for children with juvenile idiopathic arthritis (JIA) has expanded during the last decades, follow-up studies are needed on children diagnosed in the era of biological treatment to evaluate if this has improved the outcome. Our aim was to study the epidemiology and outcome of JIA in southern Sweden using a population-based cohort of children with a validated di
The development of the intraovarian adrenergic nervous system was investigated in the guinea-pig by use of chemical determination of catecholamines with high performance liquid chromatography (HPLC) and with the formaldehyde-induced fluorescence method for visualization of adrenergic nerves (Falck-Hillarp technique). Ovaries from fetuses (39-40, 45-50, 55-57, 60-63 days of gestation) and young ani
