Popular Abstract in Swedish Kvantprickar är objekt där elektroner är instängda i en mycket liten volym (av storleksordningen 100 nanometer i varje riktning). I den här avhandlingen har vi studerat kvantprickar definierade i nanotrådar av halvledarmaterial. Nanotrådarna kan vara flera mikrometer långa men samtidigt mycket tunna (mindre än 100 nanometer eller 0,1 mikrometer). Vi har skapat kvantpriThis thesis focuses on electrical transport in semiconductor InAs nanowires grown by chemical beam epitaxy. Initially, transport length scales of homogeneous InAs n-type nanowires are characterized by low-temperature magnetoconductance measurements. The measurements show phase-coherent conductivity corrections. By fitting the data, we find the nanowire mean-free path to be 50 nm and the phase-cohe

Three nuclei with mass number A=61 have been studied using four fusion-evaporation experiments carried out at the Oak Ridge, Argonne and Lawrence Berkeley National Laboratories. Normally deformed states in 61Ga were for the first time ever explored and in addition the experimental knowledge of the mirror nucleus 61Zn was extended. The two nuclei together provide the possibility to explore mirror

Contemporary economic landscapes are particularly active with mergers, acquisitions, bankruptcies, and corporate takeovers, and the set of managerial elite who are in decision making positions are inextricably connected to these events. In this thesis I offer an anthropological perspective of these dynamics by considering the possible connection between processes of trans- national capitalist elit

The Conference on Computational Natural Language Learning is accompanied every year by a shared task whose purpose is to promote natural language processing applications and evaluate them in a standard setting. In 2008 the shared task was dedicated to the joint parsing of syntactic and semantic dependencies. This shared task not only unifies the shared tasks of the previous four years under a uniq

Popular Abstract in Swedish Traditionellt sett är resande en maskulin aktivitet. I det här sammanhanget betyder det att resan för en euro-amerikansk man ses som en identitetsskapande process som formar honom som subjekt. Denna process förutsätter att kvinnan figurerar i marginalen, i det stereotypiska fallet som sexobjekt eller väntande hustru/moder. Genom att ersätta män med kvinnor i huvudrollerThis thesis is founded on the premise that traditional discourses of travel and mobility are inherently masculinist, that is, travel is seen as a masculinity rite-of passage for the Euro-American male, shaping his subjectivity through the othering and marginalization of women. Taking Jack Kerouac’s On the Road (1957), the epitome of masculinist travel literature, as a starting point for an examina

Piezoelectric ceramics -- as one widely commercialised group of smart materials -- exhibit a great potential for various engineering applications. Their high-frequency capabilities are in particular attractive for actuator and sensor devices, which nowadays are present in daily-life-technologies such as cellular phones, fuel injection systems, and so forth. At high loading levels however, severely

uses a microporous membrane operated in cross-flow. The continuous phase is pumped along the membrane and sweeps away dispersed phase droplets forming from pore openings as shown in Figure 1. The key feature of the membrane emulsification process, which sets it apart from conventional emulsification technologies, is that the size distribution of the resulting droplets is primarily governed by the
