Global catchment modelling usingWorld-Wide HYPE (WWH), open data, and stepwise parameter estimation

Recent advancements in catchment hydrology (such as understanding catchment similarity, accessing new data sources, and refining methods for parameter constraints) make it possible to apply catchment models for ungauged basins over large domains. Here we present a cutting-edge case study applying catchment-modelling techniques with evaluation against river flow at the global scale for the first ti

Two-dimensional OH-thermometry in reacting flows using photofragmentation laser-induced florescence

In the present work, the possibility of using photofragmentation laser-induced fluorescence (PFLIF) for thermometry in different reacting flows is investigated. Hydroxyl (OH) fragments are created by UV-laser (266nm) fragmentation of hydrogen peroxides (H2O2 and HO2), whereupon the fluorescence, induced while scanning the wavelength of a second laser across the A2σ+(v = 1)-X2Π(v = 0) absorption ba

Characteristic Properties and Applications of Fine Particles in Biomass Gasification

Popular Abstract in Swedish Many of the energy needs in today’s modern society are fulfilled by sources based on fossil fuels, including non-domestic oil and coal. It is well known that the increase in CO2 emission is the result of human activities, mostly fossil fuel consumption. The use of such fuels is unsustainable and has led to the phenomena such as climate change, political instability in sThe gasification of biomass is a promising route to increase the share of renewable sources in the energy mix. Besides having an overall higher thermal efficiency than combustion, it also offers the possibility of producing gaseous and liquid biofuels that can be used in the transport sector. The use of biomass gasification for energy purposes can help lower the net emissions of greenhouse gases,

Species interactions in streams - effects of predation, competition and ecosystem properties

Popular Abstract in Swedish Hur är grannsämjan i skånska vattendrag?

Grönling, öring och signalkräfta är tre vanligt förekommande arter i rinnande vatten i Skåne. Öringens biologi och ekologi är väl undersökta och den är dessutom en populär sportfisk. Signalkräftan inplanterades i slutet på 1960-talet för att ersätta den inhemska flodkräftan och är även den ekonomiskt viktig, samt Stream ecosystems are dynamic and they have an inherent environmental variability. Organisms that live in streams are adapted to the continuously changing environment and the presence or absence of species are determined by their environmental requirements, while abundance is most often affected by interactions, such as competition and predation, with other species that are found in the same habit

A model for peak and width of signaling windows: Ips duplicatus and Chilo partellus pheromone component proportions - Does response have a wider window than production?

Pheromone communication systems have a reliable signal with a restricted window of amounts and ratios released and perceived. We propose a model based on a Gaussian response profile that allows a quantification of the response peak (location of optimum) and a measure of the peak width (response window). Interpreting the Gaussian curve, fitted by nonlinear regression (NLR), as a standard normal dis

Thyroid-Stimulating Hormone, Thyroglobulin, and Thyroid Hormones and Risk of Differentiated Thyroid Carcinoma: The EPIC Study

Background Increased levels of thyroglobulin (Tg) and thyroid-stimulating hormone (TSH) are associated with differentiated thyroid carcinoma (TC) risk, but strong epidemiological evidence is lacking. Methods Three hundred fifty-seven incident TC case patients (n = 300 women and 57 men; mean age at blood collection = 51.5 years) were identified in the EPIC cohort study and matched with 2 (women) or

On the Antenna-Channel Interactions: A Spherical Vector Wave Expansion Approach

The main focus of this thesis is the analysis of the interactions between antennas and channels where electromagnetic fields play a central role. Our goal has been to devise a general framework to enable a clear separation of the properties of the propagation channel from the influence of the antennas at the same time as it provides a common ground for a joint characterization of their properties.

A Sequential Control Language for Industrial Automation

Current market trends for industrial automation are the need for customizable production, shorter time to market, and powerful global competitive pressure. Based on these trends two challenges have been identified: 1) flexible production systems and 2) integration and utilization of devices and software. Applications from both process automation, manufacturing, and robotics have been considered.

Knowledge and Survival in the Novels of Thomas Hardy

Popular Abstract in Swedish Min avhandling heter Knowledge and Survival in the Novels of Thomas Hardy (disputationsdag: 15 april 2000). Jag fokuserar på två sorters vetande: det traditionella, som jag kallar ‘det vardagliga’, och ‘det specialiserade’, som är knutet till modern vetenskaplig utveckling.Abstract This thesis identifies two different kinds of knowledge in Thomas Hardy's novels: the everyday, passed on from generation to generation, which is non-academic and closely bound to the local environment and its traditions; and the specialised, recorded in the printed word, which is the product of formal education and independent of the local community and its traditions. These two kinds o

Retroviral gene transfer to repopulating hematopoietic cells

Popular Abstract in Swedish Blodbildande stamceller förekommer i mänsklig benmärg i en frekvens på ca 1/100 000 celler. Med hjälp av cellytemarkörer, t.ex. CD34, kan man rena fram cellpopulationer som är anrikade på stamceller, men det saknas exakt kunskap om hur enskilda stamceller ser ut. De blodbildande stamcellerna har förmåga att vid celldelning antingen förnya sig själva eller att mogna ut. Hematopoietic stem cells (HSCs) have the capacity to maintain hematopoiesis throughout life. HSCs are ideal targets for permanent gene transfer, as the transgene will be expressed in all the progeny of the gene-modified stem cells. The aim of this thesis was to optimize conditions for retroviral gene transfer to human candidate HSCs and to study mechanisms interfering with efficient gene transfer.

Världar i Brand. Fiktion, politik och romantik i det tidiga 1900-talets ungsocialistiska press

Popular Abstract in Swedish När vi tänker på skönlitteraturen får den gärna en drömmande klang som för tankarna till främmande platser långt borta från vardagen. Samtidigt kan skönlitteraturen måla upp slående bilder av världen och övertygande sätta in politiska och kulturella frågor i ett större meningsfullt sammanhang. Ingenstans blir detta tydligare än i Brands skönlitteratur. I det ungsocialisThis study delves into the relationship between fiction and politics, aesthetic and ethical messages conveyed by the fictions of Brand (Fire), the journal of the Young Socialist Association, founded as the Social Democratic Labour Party’s first youth association. The literary and aesthetic arena allowed many different kinds of ideas and thoughts to flourish, making Brand an important cultural pape

Medborgarskap efter nationalstaten? : Ett konstruktivt förslag

Popular Abstract in Swedish För drygt ett decennium sedan beslutade EU:s dåvarande tolv medlemsstater att upprätta ett gemensamt europeiskt medborgarskap för unionens invånare. Alltsedan dess har det europeiska medborgarskapet varit en omdiskuterad och kontroversiell, men för den breda allmänheten tämligen okänd, innovation i den europeiska integrationen. I Medborgarskap efter nationalstaten ? ettThis thesis is an attempt to formulate a constructive proposal for the ongoing establishment of a post-national European citizenship in the European Union. To the extent that the proposal is post-national, the ambition is to re-conceptualise the idea and ideal of citizenship in a new historical setting. To the extent that the proposal is constructive, the ambition is to develop and employ a method

Calibration and assessment of channel-specific biases in microarray data with extended dynamical range

Background: Non-linearities in observed log-ratios of gene expressions, also known as intensity dependent log-ratios, can often be accounted for by global biases in the two channels being compared. Any step in a microarray process may introduce such offsets and in this article we study the biases introduced by the microarray scanner and the image analysis software. Results: By scanning the same sp

Sleep disturbance in association with elevated pulse rate for prediction of mortality--consequences of mental strain?

OBJECTIVES: Sleep deprivation has experimentally been shown to adversely influence glucose metabolism, endocrine function and sympathovagal balance in young men without known serious disease. We investigated the impact of sleep problems and resting heart rate in a large sample of self-reported, healthy middle-aged men and women on long-term mortality. METHODS: In all 22,444 men and 10,902 women pa
