The current Lambda Cold Dark Matter cosmology predicts galaxy growth by hierarchical merging, leading to galaxy substructure like tidal streams and dark matter subhalos devoid of stars. The goal of this thesis is to investigate whether tidal stream-subhalo interactions can leave observable gaps in the streams, and at which rate this might happen in a galaxy like the Milky Way. The stream-subhalo i

We investigate a class of random graph ensembles based on the Feynman graphs of multidimensional integrals, representing statistical-mechanical partition functions. We show that the resulting ensembles of random graphs strongly resemble those defined in random graphs with hidden color, generalizing the known relation of the Feynman graphs of simple one-dimensional integrals to random graphs with a

The principle of mutual trust has been a central pillar of the European integration project, first as a tool for market integration, and as the European Economic Community became the European Union, as a mechanism for a more wide ranging integration of the legal orders of the member states. The EU now has legislation in place which imposes obligations on member states to trust each other's civil a

Urban establishment from scratch based on a smart city vision has been mainstreamed as a strategy to achieve urban sustainability goals. However, the smart city model itself has been criticized because of how the techno-centric solutions it uses could potentially lead to economic and social inequality. Urban Political Ecology (UPE) focuses on how the urban production process involve commodificatio

China's accession to the WTO was perceived as the West integrating the East into the international economy with market economy reforming the planned economy. The major actors, the United States (US) and the Euorpean Union (EU), with similar economic structures and ideologies were expected to cooperate and bargain the best offers from China. However, while the US adopted a confrontational appro

X-ray imaging can be improved by utilising the wave-optical properties to extract images of complementary contrast. Normal x-ray imaging relies only on attenuation in the sample, but information about phase shift and scattering of the x-rays can be computed when special conditions are fulfilled.

Social inclusion and the importance of work in developing countries has been an increasing topic of conversation during recent AIS conferences, and there are calls for research into ‘making a better world with ICT’. Trauth (2017) in her ‘Research Agenda for Social Inclusion in Information Systems’ states that “social inclusion in the information systems field is a research topic whose time has com

We consider whether stellar collisions can explain the observed depletion of red giants in the Galactic center. We model the stellar population with two different IMFs: 1) the Miller-Scalo and 2) a much flatter IMF. In the former case, low-mass main-sequence stars dominate the population, and collisions are unable to remove red giants out to 0.4 pc although brighter red giants much closer in may b

Artros är vår vanligaste ledsjukdom och kännetecknas av att brosket i leden successivt bryts ned i kombination med funktionsnedsättning samt rörelse- och belastningssmärta. Processen är långsam; brosknedbrytning pågår under flera år utan påtagliga symptom. Först långt fram i processen syns röntgenologiska förändringar. Enligt evidensbaserade riktlinjer är den primära behandlingen fysioterapi och iOsteoarthritis (OA) is the most frequently occurring joint disease and is characterized by a gradual degradation of joint cartilage as well as pain and loss of function. The disease progression is slow; degradation of cartilage occurs for several years prior to symptoms. Radiological changes occur much later in the process. According to current evidence-based guidelines, the primary treatment is p

We have traced the Galactic thick disk to its, to date, highest metallicities. Based on high-resolution spectroscopic observations of 187 F and G dwarf stars that kinematically can be associated either with the thin disk (60 stars) or with the thick disk (127 stars), we find that the thick disk stars reach at least solar metallicities, and maybe even higher. This finding is independent of the U_LS
