This study examine the roles of bloggers in Web 2.0. Blogging is considered to be a fairly new phenomenon and blog authors are increasingly seen as producers of user-­generated content wielding influence on both their readers and respective industries. Thus, it is argued that recognizing the different roles assumed by bloggers will shed light on the importance of bloggers and how this may affect m

Fjärrvärme är en teknologi som har stor potential att bidra till att möjliggöra ett fossilfritt samhälle. För att uppnå denna potential, finns det dock en del förbättringar som måste göras för att förbättra fjärrvärmeverksamheten i stort, minska förlusterna från systemen och därmed öka konkurrenskraften hos fjärrvärme som teknologi. Ett flertal studier har visat att ett sätt att göra detta, och däDistrict Heating is a technology with the potential to enable a fossil-free society. However, to realize this potential, some improvements need to be made in order to improve District Heating operation at large, decrease losses in the systems, and thus increase the competitiveness of District Heating as a technology. Several have shown that a possible solution, to increase the efficiency of Distri

This study investigated how individuals combine information learned across temporally separate events in order to make novel inferences through memory integration, utilising EEG to provide a novel investigation with high temporal resolution. Participants completed an associative inference task (Zeithamova & Preston, 2010) modified for EEG across three experiments, during which they learned st

A concern about the democratic legitimacy of the European Union is a frequent topic when discussing European integration. How can democratic principles be withheld when political power is delegated from the nation-state to a supranational level? Can democracy be secured beyond the nation-state? This thesis derives from a deliberative perspective, which emphasises the need for debate in democratic

One of the fundamental processes in nature is the photoelectric effect in which an electron is ripped away from its atom via the interaction with a photon. This process was long believed to be instantaneous but with the development of attosecond pulses (1 as 10(-18) s) we can finally get an insight into its dynamic. Here we measure a delay in ionization time between two differently bound electrons

Piratverksamhet är inte speciellt uppmärksammat i västvärlden – media lyfter inte upp det och det är heller inte en speciellt prioriterad punkt på politikernas agenda. Det betyder dock inte att det inte är ett stort problem. Det påverkar många, både känslomässigt och ekonomiskt, på en individnivå men också på en nationell, regional och global nivå. Problemet är komplext och har en lång historia,

We have prepared nanomaterials consisting of SiO 2 microgranules and Fe-containing nanoparticles on their surface and determined the size and composition of the nanoparticles. The nanoparticles are shown to have a core-shell structure (α-Fe core and γ-Fe 2O 3 shell). The α-Fe core and Fe 2O 3 shell are responsible, respectively, for the broad and narrow lines in the EMR spectrum of the nanoparticl

Over the last decade significant research efforts have been devoted to the probabilistic modeling and analysis of system characteristics. Especially performance characteristics of systems subjected to random disturbances, such as robustness and resilience have been in the focus of these efforts and significant insights have been gained. However, as much of the undertaken research and developments

 Immune thrombocytopenia (ITP) is an autoimmune bleeding disorder mediated by antiplatelet autoantibodies and antigen-specific T cells that either destroy platelets peripherally in the spleen or impair platelet production in the bone marrow. There have been a plethora of publications relating to the pathophysiology of ITP and since January of 2019, at least 50 papers have been published on ITP pat

The last decade has seen a revival of interest in pebble games in the context of proof complexity. Pebbling has proven to be a useful tool for studying resolution-based proof systems when comparing the strength of different subsystems, showing bounds on proof space, and establishing size-space trade-offs. The typical approach has been to encode the pebble game played on a graph as a CNF formula an

In a wish to abandon essentialism to contingency, this paper looks into whether the rural-urban binary could be a cultural burden so incompatible with the layered realities of advanced deprivation that instead of helping the deprived, it deprives the help of its carrying capacity. Departing from the idea that cultural mechanisms are capable of allowing for conceptual dichotomies to create oppressi

ANCA-associated vasculitis (AAV) includes granulomatosis with polyangiitis, microscopic polyangiitis and eosinophilic granulomatosis with polyangiitis. Epidemiological studies in AAV are important in understanding possible aetiologic mechanisms and facilitating healthcare planning. However, epidemiological studies present a number of challenges including clear definition of cases differentiated fr

An orientation of a graph G is a digraph D obtained from G by replacing each edge by exactly one of the two possible arcs with the same endvertices. For each v∈V(G), the indegree of v in D, denoted by dD-(v), is the number of arcs with head v in D. An orientation D of G is proper if dD-(u)≠dD-(v), for all uv∈E(G). The proper orientation number of a graph G, denoted by χ→(G), is the minimum of the

We present experimental measurements and theoretical calculations of single and double ionization time delays in various noble gases using an interferometric method. The measured delays allow us to extract information on the electron correlation.
