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
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
We have earlier shown that radio frequency electromagnetic fields can cause significant leakage of albumin through the blood-brain barrier of exposed rats as compared to non-exposed rats, and also significant neuronal damage in rat brains several weeks after a 2 h exposure to a mobile phone, at 915 MHz with a global system for mobile communications (GSM) frequency modulation, at whole-body specifi
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 European Union's Natura 2000 (N2000) is among the largest international networks of protected areas. One of its aims is to secure the status of a predetermined set of (targeted) bird and butterfly species. However, nontarget species may also benefit from N2000. We evaluated how the terrestrial component of this network affects the abundance of nontargeted, more common bird and butterfly specie
Background: Adolescent depression is a common mental health problem and there is an urgent need for effective and accessible treatments. Internet-based interventions solve many obstacles for seeking and receiving treatment, thus increasing access to effective treatments. Internet-based cognitive behavioural therapy (ICBT) for adolescent depression has demonstrated efficacy in previous trials. In o
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
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
This thesis is considering various aspects of electronic transport through quantum dots, with the focus on two or three dots coupled in series.In paper I, we study the impact of electron-electron interactions on transport in a system of triple quantum dots with spin. We show that due to electron-electron scattering processes, transport is possible beyond the common single-particle transmission cha
This paper presents a pilot study of the collaborative interaction between industrial design and engineering design in a significant productdevelopment project at a major Swedish vehicle manufacturer. Since industrial and engineering design have different approaches to productdevelopment, they require careful integration to reach their full potential, to reach project goals, and to ensure the inno
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
Outcome questionnaires are increasingly being established as a validated mode of acquiring unbiased information on the results after health interventions. Using an assortment of questionnaires, distributed by mail to 27 372 and to a subgroup of 3 600 patients on file in the Swedish Knee Arthroplasty register (SKAR), relevant questionnaires were found to represent a feasable means of acquiring info
This study investigates strategies for igniting hydrogen in compression ignition engines, a process traditionally hindered by hydrogen’s high ignition temperature. In conventional dual-fuel engines, a small diesel pilot is often used to ignite hydrogen, taking advantage of diesel’s lower ignition temperature to initiate combustion. While effective, this approach introduces carbon emissions, limiti
Digitalization is transforming the tax landscape, reshaping the operations of tax departments, authorities, and professionals. With rapid digital advancement, there has been a shift toward real-time reporting, e-invoicing, and greater reliance on digital data. This change is driven by investments in data analytics, robotic process automation, cloud platforms, and, more recently, artificial intelli
This paper describes measurements of the transverse momentum spectra of W and Z bosons produced in proton–proton collisions at centre-of-mass energies of s=5.02 TeV and s=13 TeV with the ATLAS experiment at the Large Hadron Collider. Measurements are performed in the electron and muon channels, W→ℓν and Z→ℓℓ (ℓ=e or μ), and for W events further separated by charge. The data were collected in 2017
Hard alumina-based coatings can be applied to cast iron brake discs using a plasma electrolytic aluminating (PEA) process to enhance wear and corrosion resistance and reduce brake particle emissions. This work was first to study the influence of friction wear on corrosion property and then investigate the influence of corrosion on brake particle emissions from cast iron discs through comparison of
