The ADVEX project involved conducting extensive advection measurements at three sites, each with a different topography. One goal of the project was to measure the [CO2] balance under night-time conditions, in an attempt to improve NEE estimates. Four towers were arranged in a square around a main tower, with the sides of the square about 100 m long. Equipped with 16 sonic anemometers and [CO2] sa
Innovation is an interactive learning process that is facilitated naturally by geographic proximity. Innovation intermediaries can serve as an extra catalyst to and facilitator of interaction and collaboration. With today’s more globalized knowledge and innovation landscape, companies and research organizations seek complementary competencies and partners with whom they can collaborate on a much b
In an organization where the safety level is high and incidents and serious accidents are very rare, a steady erosion of safety awareness and protective measures can occur, especially when productive demands rise. Thus, it is important to continuously identify and monitor aspects in the organization that can affect work performance and safety. In an ongoing joint research project between the LFV G
A reduction of the negative environmental impact caused by urban traffic will to a considerable extent depend on behavioural change. Assuming that attitudes partly guide behaviour, the general aim of the thesis was to increase the understanding of the underlying attitudes of daily travel behaviour and how attitudes related to pro-environmental choice of transport can be promoted. Two questionnaire
The present thesis investigates the usage of cultural heritage resources on the web. In recent years cultural heritage objects has been digitalized and made available on the web for the general public to use. The thesis addresses to what extent the digitalized material is used, and how findable it is on the web. On the web resources needs to be findable in order to be visited and used. The study i
By means of a myograph, postjunctional alpha-adrenoceptors were characterized in human superficial epigastric arteries and veins obtained from health subjects. The rank order of potency of subtype selective agonists could not be used for receptor characterization in these vessels, whereas antagonists gave distinct results. It was found that the arteries were endowed mainly by alph1-adrenoceptors b
Popular Abstract in Swedish Avhandlingens syfte var att utveckla en checklista för bedömning av utemiljön i flerfamiljs bostadsområden.

The checklist was validated against a Post-occupancy evaluations form (POE) that was d
Popular Abstract in Swedish I slutet av 1800-talet gjordes upptäckten att atomer bara kan ta upp eller sända ut ljus med vissa våglängder. Denna egenskap beror på att elektronerna endast kan befinna sig i ett av flera diskreta energitillstånd. Man säger att elektronerna är kvantiserade. Kvantiseringen är en effekt av att elektronerna i en atom tvingas hålla sig inom en mycket liten volym. Ju mindrIn this thesis, spectroscopic studies of quantum wells (QWs), quantum wires (QWRs) and quantum dots (QDs) in III-V semiconductors are presented. The electronic structure of these low-dimensional structures have been studied by absorption, photocurrent, electroreflectance, photoluminescence (PL), and photoluminescence excitation (PLE) spectroscopy. The band alignment of GaAs pseudomorphically grow
Background. Studies suggest an increased risk for compromised cognitive function among cancer survivors. It is unclear to what extent chemotherapy is the cause and how the dysfunction, when present, affects everyday life. The objective was to study self-reported behaviours that may depend on cognitive function, among testicular-cancer survivors who received various cycles of cisplatin-based chemot
We present an extensive rheology study of the wormlike micelle system lecithin-water-cyclohexane. In this system the micelles are really wormlike, meaning that there are no signs of micellar branching, as it has previously been demonstrated by NMR self-diffusion experiments (R. Angelico, U. Olsson, G. Palazzo and A. Ceglie, Phys. Rev. Lett., 1998, 81, 2823). Wormlike micelles break and recombine,
Popular Abstract in Swedish Syftet med min avhandling är att utforska vilken funktionell roll naturliga mördar T (NKT) -celler har, samt vilka gener som är viktiga för dessa celler. NKT-celler utgör en liten men specialiserad undergrupp av T-celler, och är mycket intressanta eftersom att de, trots att de tillhör det specifika immunförsvaret, även har receptorer och egenskaper som är starkt förknipThis thesis focuses on a small population of non-conventional T lymphocytes, called natural killer T (NKT) cells. NKT cells have many unique features; such as recognition of glycolipids presented by CD1d, expression of NK receptors and rapid production of large amounts of cytokines, such as IL-4 and IFN-gamma,?upon activation. This early and robust cytokine burst is believed to give NKT cells the

Fractional moving blood volume (FMBV) estimated using power Doppler ultrasound (PDU) is a sensitive technique to detect slow blood movement. However, several factors as; depth, attenuation and blood characteristics can affect the PDU signals. The aim of this study was to standardized and validate the FMBV measurement compensating for the factors that can affect the final results, in order to accur
Popular Abstract in Swedish Vår planet är i mångt och mycket en trevlig plats att leva på, men det är också en plats där faror och hot kan lura bakom varje hörn. Dessa hot kan vara av olika karaktär, till exempel kan det röra sig om risken att bli jagad och uppäten, att drabbas av uttorkning eller något annat obehagligt. Vår planets invånare har utvecklat en mängd olika strategier för att hantera Most organisms on Earth live a life where they are exposed to multiple and variable threats. In order to maximise survival they need to be able to perceive and respond to these threats. Two common threats that crustacean zooplankton are faced with are predation and ultraviolet radiation (UVR). To cope with these threats zooplankton use different strategies such as diel vertical migration and the a

Popular Abstract in Swedish En magnetkamera kan med hjälp av diffusionsviktad bildtagning användas för att avbilda hjärnans nervsystem. Denna teknik kan utnyttjas för studier av hur hjärnans delar är sammankopplade, men även för att indirekt mäta egenskaper hos hjärnans mikrostruktur. Detta avhandlingsarbete vidareutvecklar de biofysikaliska modeller och mätmetoder som används för denna indirekta Diffusion MRI is widely used to study brain structure in vivo. While this technique is often applied to investigations of brain connectivity, it can also be used to infer specific information about the tissue microstructure; for example, to estimate the axon diameter. In the present work, the role of tissue microstructure and water exchange in biophysical models employed in diffusion MRI was inves
