Syftet med examensarbetet är att analysera om BFN stötte på problem vid upparbetningen, samt om vår expert och redovisningsekonomerna tror samma problem kommer att uppstå vid tillämpningen. Ändamålet är även att beskriva varför dessa kommer att bli problematiska och om andra problem kommer att uppstå. I teorin beskrivs gällande regelverk och kommande K2-regelverket för belysta problemområden samt
The Swedish retail landscape is currently undergoing a transformative change with increased digitalization and a rapidly growing e-commerce sector, which creates both opportunities and challenges. The development towards omnichannel commerce creates a more complex customer journey and results in complex environmental challenges. E-commerce deliveries to consumers, in particular, pose a complex soc
We propose a geometric model to estimate the contribution of substrate surface diffusion to growth of dense nanowire arrays using metalorganic vapour phase epitaxy. It is shown that the nanowire mantle area becomes the most significant collector of growth material when the nanowire diameter is large and the inter-nanowire pitch is small. It is concluded that this growth regime is important for the
Surface tension is crucial for nanowire vapor liquid solid (VLS) growth models and simulations of growth under external stimuli. A promising method involving imaging droplet deformation under an external electric field has previously been used to report the surface tension of the AuSi eutectic catalyst on Si-nanowires. However, simplified assumptions in this approach led to a significantly lower v
In this 5th version of the European LeukemiaNet guidance for adult patients, there are important changes in several areas of management based on evidence available since 2020, including the World Health Organisation’s reclassification of CML as a biphasic disease. Previous advice to switch the tyrosine kinase inhibitor (TKI) on failure of molecular milestones, is modified to better account for ind
IntroductionThis paper focuses on retailing in vulnerable areas, which are commonly associated with segregation,crime, violence, and unsafety (Swedish Police Authority, 2023; Gerell et al., 2021). Less attention isusually paid to the conditions of retailing in these neighbourhoods. A well-functioning grocery storecan be a decisive factor in the attractiveness of an area and in making it safe. At t
Lung transplantation is currently the only option for patients with end-stage respiratory diseases, but owing to various complications and adverse effects of the treatment in combination with the increasing demand for and limited access to donor organs, new strategies are needed. Recent advances in materials science, culture techniques, cell-phenotyping and isolation techniques, bioreactor enginee
Although AlGaN/GaN HEMTs with high power and current gain have been demonstrated in RF device applications, at high signal operation they show an inherent non-linear behavior which leads to gain compression and signal distortion. Polarization-doped AlGaN/GaN HEMTs, with a compositionally graded channel enables a linear response improvement through formation of a 3-D electron gas. In this work, we
Lysozyme is known to form equilibrium clusters at pH ≈ 7.8 and at low ionic strength as a result of a mixed potential. While this cluster formation and the related dynamic and static structure factors have been extensively investigated, its consequences on the macroscopic dynamic behavior expressed by the zero shear viscosity η
We present an electrode, based on structurally controlled nanowires, as a first step towards developing a useful nanostructured device for neurophysiological measurements in vivo. The sensing part of the electrode is made of a metal film deposited on top of an array of epitaxially grown gallium phosphide nanowires. We achieved the first functional testing of the nanowire-based electrode by perform
Det krävs åtgärder på flera nivåer för att minska utsläppsnivåerna från vägtrafiken. I denna uppsats studeras möjligheten att använda förarstöd för att minska den totala bränsleförbrukningen och emissionerna. Detta är gjort med en litteraturstudie som beskriver vad som påverkar bränsleförbrukningen och utsläpp av emissioner generellt, ur ett förarperspektiv samt vid användning av förarstöd med mil
Amyloid fibrils are the most distinct components of the plaques associated with various neurodegenerative diseases. Kinetic studies of amyloid fibril formation shed light on the microscopic mechanisms that underlie this process as well as the contributions of internal and external factors to the interplay between different mechanistic steps. Thioflavin T is a widely used noncovalent fluorescent pr
Background and Purpose-Genetic variation influences risk of intracerebral hemorrhage (ICH). Hypertension (HTN) is a potent risk factor for ICH and several common genetic variants (single nucleotide polymorphisms [SNPs]) associated with blood pressure levels have been identified. We sought to determine whether the cumulative burden of blood pressure-related SNPs is associated with risk of ICH and p
A method to fabricate inorganic vertical spacer layers with well-controlled thickness down to 40 nm using electron beam exposure is demonstrated. These spacers are suitable in vertical nanowire transistor configuration. As spacer material, the authors use hydrogen silsesquioxane (HSQ), a material with low permittivity and high durability. They show that the resulting HSQ thickness can be controlle
We use time-dependent density functional theory together with a set of extensive multidimensional visualization techniques to characterize band gap, optical absorption properties, intramolecular and intern-wreaths charge transfer, exciton binding energy, charge transfer integral, and the rate of charge transfer and recombination in the PC60BM:PDDTT Model of an organic,solar cell. These theoretical

Hypertension clusters in families. However, no nationwide study has investigated the family history as a predictor of hospitalization for hypertension, which was the purpose of this study.
Technology that facilitates rapid investigation of solid phase extraction protocols using very small amounts of sorbent can save both time and money. The microfabricated ISET (Integrated Selective Enrichment Target) interfaced with MALDI mass spectrometry is able to provide an efficient, economic and generic optimization process for SPE sample preparation. The SPE is performed in a rapid and paral
Lifestyle interventions (i.e., diet and/or physical activity) are effective in delaying or preventing the onset of diabetes and cardiovascular disease. However, policymakers must know the cost-effectiveness of such interventions before implementing them at the large-scale population level. This review discusses various issues (e.g., characteristics, modeling, and long-term effectiveness) in the ec
Molecularly imprinted polymers (MIPs) have a predesigned molecular recognition capability that can be used to build robust chemical sensors. MIP-based chemical sensors allow label-free detection and are particularly interesting due to their simple operation. In this work we report the use of thiol-terminated MIP microspheres to construct surfaces for detection of a model organic analyte, nicotine,
