In cases of suspected scaphoid fracture where the initial radiographs are negative, a supplementary MRI, or alternatively CT, should be carried out within three to five days. Fracture classification, assessment of dislocation as well as evaluation of fracture healing is best done on CT with reconstructions in the coronal and sagittal planes, following the longitudinal axis of the scaphoid. After a

This thesis deals with physical limitations on scattering and absorption of acoustic and electromagnetic waves. A general dispersion relation for the extinction cross section of such waves is derived from the holomorphic properties of the scattering amplitude in the forward direction. The result states that for a given volume, there is only a limited amount of scattering and absorption available i

The Neumann–Neumann method is a commonly employed domain decomposition method for linear elliptic equations. However, the method exhibits slow convergence when applied to semilinear equations and does not seem to converge at all for certain quasilinear equations. We therefore propose two modified Neumann–Neumann methods that have better convergence properties and require fewer computations. We pro

The purpose of this thesis is to explore the possibilities of minimising waste generation in the healthcare institutions in Kaliningrad, Russia. In order to meet this purpose the following research question is investigated: what kind of drivers are enforcing and which barriers are hindering waste minimization in the healthcare sector in Kaliningrad? The research carried out among public and priva

The number of situations where both people and nature are harmed by human activities are increasing in the same pace as mankind is augmenting its control and so called 'development' of the Earth. Although previously much debated, we have passed the stage when protecting human rights and preserving the environment were seen as conflicting interests. Instead we have reached the conclusion th

The growing energy prices and energy consumption caused the interest about buildings with low energy consumption such as Passive house. Energy demand in households accounts for around one forth of the final energy needs in the EU (Intelligent Energy Europe 2006), and it is a potential for energy demand reduction. At the same time, environment protection with a reduction of CO2 emissions nowadays i

Cell-Free networking is one of the prime candidatesfor 6G networks. Despite being capable of providing the 6Gneeds, practical limitations and considerations are often neglectedin current research. In this work, we introduce the conceptof federations to dynamically scale and select the best set ofresources, e.g., antennas, computing and data resources, to servea given application. Next to communica

In this work, we describe a new Monte Carlo (MC) simulation method to investigate highly coupled fluids in confined geometries at a constant chemical potential. This method is based on so-called multi-scale Hamiltonian methods, wherein the chemical potential is determined using a more amenable Hamiltonian for a fluid in an "outer"region, which facilitates standard methods, such as grand canonical

Previous research has argued that related variety enhances regional innovation as inter-industry knowledge spillovers occur more easily between cognitively similar industries. In this study, we engage with empirical operationalization of what is ‘related’ in related variety. We argue, based on theoretical grounds, that estimating regional knowledge production functions requires related variety mea

This work investigates dovetail joints as a means to mount pre-wound coils in an electrically excited rotor for a synchronous machine for EV application. The aim is to manufacture a prototype of a direct cooled machine with hollow rectangular rotor windings which requires a rotor design where the windings can be applied on the poles separately. Two experimental tensile tests are made to validate t

Galectins are a family of soluble proteins that bind β-D-galactopyranoside-containing glycoconjugates through their conserved carbohydrate-recognition domains. Galectins have emerged as promising drug targets due to their involvement in various pathological conditions, such as tumor growth and metastasis, autoimmune and inflammatory diseases, as well as metabolic disorders.This first part of the t

Type 1 diabetes is a complex disease characterized by the lack of endogenous insulin secreted from the pancreatic β-cells. Although β-cell targeted autoimmune processes and β-cell dysfunction are known to occur in type 1 diabetes, a complete understanding of the cell-to-cell interactions that support pancreatic function is still lacking. To characterize the pancreatic endocrine compartment, we stu

This thesis concerns the investigation of direct and inverse resonance results for the Love and the Rayleigh operators, which arise from decoupling the three-dimensional elastic wave equation in the semiclassical limit in the half-space. Direct resonance results in terms of the asymptotic distribution of resonances in the complex plane are obtained for the Love and the Rayleigh operators. An inver

Pollinators are critical for food security; however, their contribution to the pollination of locally important crops is still unclear, especially for non-bee pollinators. We reviewed the diversity, conservation status, and role of bee and non-bee pollinators in 83 different crops described either as important for the global food market or of local importance. Bees are the most commonly recorded c

This paper focuses on tech giants as active drivers of a phase of globalization characterized by growth in digital services trade combined with a general shift to intangible assets. By analysing how Google, Amazon and Microsoft organize their innovation activities, we show that they continuously monopolize knowledge while outsourcing innovation steps to other firms and research institutions. The p

Tensor-valued diffusion encoding facilitates data analysis by q-space trajectory imaging. By modeling the diffusion signal of heterogeneous tissues with a diffusion tensor distribution (DTD) and modulating the encoding tensor shape, this novel approach allows disentangling variations in diffusivity from microscopic anisotropy, orientation dispersion, and mixtures of multiple isotropic diffusivitie
