This presentation discusses an ongoing research project that aims to collect data about the practice of information search. It seeks to learn more about different ways in which tourist information is collected at different stages of a journey. Speaking to tourism planners and reading tourism research, it seems as if the digitalization of information has completely changed tourists’ information sea
Increased awareness, interest and use of assistive technology (AT) presents substantial opportunities for many citizens to become, or continue being, meaningful participants in society. However, there is a significant shortfall between the need for and provision of AT, and this is patterned by a range of social, demographic and structural factors. To seize the opportunity that assistive technology
In this study, we examined the evolutionary outcome of and interplay between historic isolation and current selection pressures on traits more or less closely connected to fitness in the Pearly Heath butterfly (Coenonympha arcania) across its range in Europe. We hypothesized that a trait mean is more related to historic events if it has low connection to fitness, while a trait more closely connect
This study investigates machining superalloy Inconel 718 with polycrystalline cubic boron nitride (pcBN) tooling both numerically and experimentally. Particular attention is given to mechanical and thermal stresses in the cutting tool arising from segmented chip formation and associated forces and temperatures. The temperature dependence of the mechanical properties of pcBN has been investigated a
Vehicle-to-vehicle (V2V) wireless communications can improve traffic safety at road intersections and enable congestion avoidance. However, detailed knowledge about the wireless propagation channel is needed for the development and realistic assessment of V2V communication systems. We present a novel geometry-based stochastic MIMO channel model with support for frequencies in the band of 5.2-6.2 G
Biogas production from wheat straw is one strategy of converting biomass to bioenergy, but pretreatment of the lignocellulosic material is necessary in order to render the substrate biodegradable. In this study, four different mechanical pretreatments of wheat straw were investigated: roll milling, extrusion, pelletization, and hammer milling. The effects of the pretreatments on anaerobic digestio
The pairing correlations of the nucleus 120Sn are calculated by solving the Nambu–Gor’kov equations, including medium polarization effects resulting from the interweaving of quasiparticles, spin and density vibrations, taking into account, within the framework of nuclear field theory (NFT), processes leading to self-energy and vertex corrections and to the induced pairing interaction. From these r
The closed chamber technique is widely used to measure the exchange of methane (CH4) and carbon dioxide (CO2) from terrestrial ecosystems. There is, however, large uncertainty about which model should be used to calculate the gas flux from the measured gas concentrations. Due to experimental uncertainties the simple linear regression model (first-order polynomial) is often applied, even though the
Rotor-stator mixers (RSMs) can be operated in either batch or inline mode. When operating a rotor-stator geometry in batch mode, it typically experiences an order of magnitude higher volumetric flow through the stator than in inline mode. This is expected to cause differences in the flow and turbulence in the rotor-stator region. This study uses computational fluid dynamics (CFD) to study the hydr
Although border politics have been given much theoretical attention in recent years, empirical studies of identity construction among border police officers are less common. In 2014, a two-year collaborative project partly funded by the EU was initiated in order to increase international collaboration between border police officers in the Baltic Sea area. The participating organizations were borde
Proteiner är fascinerande makromolekyler som är fundamentala för alla levandeorganismer. De utgör byggstenar i våra celler, ansvarar för transport och signalering både inom och mellan våra celler, utgör en del av vårt immunförsvar och katalyserar bildningen av andra molekyler. Proteiner består av flexibla kedjor uppbyggda av olika aminosyror. Varje aminosyra har olika egenskaper och den specifika Proteins are complex macromolecules that are fundamental to all living species. The stability of proteins are governed by non-covalent forces within the protein and between the protein and its surrounding environment. At high concentrations proteins are susceptible to self-association, which may lead to amyloid fibril formation – a process linked to many diseases, such as Alzheimer’s disease, Park
For many polar organic micropollutants, biotransformation by activated sludge microorganisms is a major removal process during wastewater treatment. However, our current understanding of how wastewater treatment operations influence microbial communities and their micropollutant biotransformation potential is limited, leaving major parts of observed variability in biotransformation rates across tr
Although conventional computer technology made a huge leap forward in the past decade, a vast number of computational problems remain inaccessible due to their inherently complex nature. One solution to deal with this computational complexity is to highly parallelize computations and to explore new technologies beyond semiconductor computers. Here, we report on initial results leading to a device
In this work we discuss a gradient plasticity formulation which relies on the introduction of higher-order gradient contributions as additional arguments of the free energy function. These gradients can be interpreted in terms of the local geometrically necessary dislocation density. This gives rise to physically well-motivated kinematic-type hardening models in contrast to purely phenomenological
The artificial replaced hip joint represents the major success story in orthopedic surgery in the twentieth century; there is much interest in extending research on hip joint even further. The stress distribution in the different bone tissues of a femur is significantly altered after an artificial replacement. Thus, there is a strong need to increase the prosthesis performance considering several
Peripheral nerve injuries are difficult to treat, and the clinical outcome after surgical repair and reconstruction is still insufficient, particularly concerning recovery of sensory function. To improve the clinical treatment strategies, experimental models are used to systematically examine the mechanisms behind nerve regeneration and assess the improvement of nerve regeneration by introduction
Although the literature on the Maillard reaction in infant formulas is extensive, most studies have focused on model systems, and in only a few cases on real food systems. Therefore, the objective of the present study was to determine the status of the Maillard reaction, both the early and advanced phases, in a variety of commercial infant formulas available on the Swedish market. Ten powder and l
We describe the iDO serious game developed during implementation of the Innovative Digital Training Opportunities on Dementia for Direct Care Workers (IDO) project. The project targets formal and informal caregivers of persons with dementia in order to improve caregiver knowledge and competences skills with a non-traditional source of training. This paper describes the steps faced to define the iD
A gardener in Småland, southeastern Sweden, tells that her father cultivated a double daylily, Hemerocallis fulva, with variegated leaves in Stockholm in the mid 20th century. When she moved to Småland, 45 years ago, she brought a piece of his plant with her, and later on she has spread the plant to others. This daylily, known as "Kwanso Variegata", was first found in Japan in 1776, and since then
