Northern high-latitude wetlands are well known to seasonally emit methane gas into the atmosphere, and therefore contribute to greenhouse effects. While these gas emissions are well documented, their causes are not well understood. The method described in this work can be used to analyze the changes happening in the soil during gas emissions, and therefore help the understanding of the sub-surface
Popular Abstract in Swedish Det är känt att kvalitén på inomhusluften har en avgörande betydelse för folkhälsan bla avseende astma, eksem samt luftvägsinfektioner. Detta är ett för samhället mycket kostsamt problem. I avhandlingen har studerats vissa luftföroreningar inomhus som kan bli följden av att en byggnad drabbats av fuktskada. När fukt påverkar byggnadsmaterial frigörs och bildas en rad oUnsatisfactory indoor air quality (IAQ) may result from polluting emissions that are spread from building materials such as volatile organic compounds (VOCs) and/or microbial components or from various kinds of human activity such as smoking. Different methods are available to limit the exposure to unwanted pollutants and improve human wellbeing and health. One goal of this thesis was to determine
This paper presents a model of long waves and an empirical analysis of Swedish growth since 1850. The model emphasises the creation of new complementarities around macro innovations. The growth process is periodised in two main parts. The first period is characterised by transformation when development is uneven and unbalanced. The second period is characterised by rationalisation when the economy
There is an urgent need to start generating energy within cities in order to pave the way for a more sustainable and resilient society. Renewable energy by means of active solar energy systems (solar thermal, ST and/or photovoltaics, PV) can be generated using roofs and facades of buildings. In this study, the annual solar energy potential of typical Swedish city blocks was analysed in order to de
A dynamic model of forest ecosystems was used to investigate the effects of climate change, atmospheric deposition and harvest intensity on 48 forest sites in Sweden (n = 16) and Switzerland (n = 32). The model was used to investigate the feasibility of deriving critical loads for nitrogen (N) deposition based on changes in plant community composition. The simulations show that climate and atmosph
Effects of a dietary combination of omega-3 polyunsaturated fatty acids (n-3-PUFA) and conjugated linoleic acids (CLAs) on fasting and postprandial plasma lipids was investigated in healthy volunteers with different ages and body mass index (BMI). Lean (BMI 20-26 kg/m2) and obese (BMI 29-35 kg/m2), young (20-37 years) and older (50-65 years) men consumed 3 g/day each of CLA and n-3-PUFA or 6 g/day
Popular Abstract in Swedish Prostatacancer är den vanligaste formen av cancer hos män i Sverige och ungefär 10 000 män diagnosticeras årligen. Prostatacancer tros orsakas av en kombination av ärftliga faktorer och miljö-/livsstilsfaktorer. De enda väletablerade riskfaktorerna för prostatacancer är ålder, etnicitet och ärftlighet inom familjer. För att kunna arbeta med förebyggande av denna sjukdomProstate cancer (PCa) is a heterogenous disease including very aggressive lethal tumors to incidentally discovered clinically insignificant tumors. Age, ethnicity, and family history are the only established risk factors. Type 2 diabetes mellitus (T2D) has been found to associate with increased overall cancer risk but with lower risk of specifically PCa. T2D is initially associated with increased
A search for production of supersymmetric particles in final states containing jets, missing transverse momentum, and at least one hadronically decaying tau lepton is presented. The data were recorded by the ATLAS experiment in root s = 7 TeV proton-proton collisions at the Large Hadron Collider. No excess above the Standard Model background expectation was observed in 2.05 fb(-1) of data. The res
A search for single top-quark production via flavour-changing neutral current processes from gluon plus up- or charm-quark initial states in proton-proton collisions at the LHC is presented. Data collected with the ATLAS detector in 2012 at a centre-of-mass energy of 8 TeV and corresponding to an integrated luminosity of 20.3 fb[Formula: see text] are used. Candidate events for a top quark decayin
Objective. To compare the effects of a restrictive versus a liberal fluid prescription, on quality of life, physical capacity, thirst and hospital admissions, in patients who had improved from NYHA class (III-)IV CHF to a stable condition without clinical signs of significant fluid overload. Design. The present study is a randomised cross-over study. Seventy-four patients (mean age 70 +/- 10 years
Signaling by the receptor for stem cell factor (SCF), c-Kit, is of major importance for hematopoiesis, melanogenesis and reproduction, and the biological responses are commonly proliferation and cell survival. Thus, constitutive activation due to c-Kit mutations is involved in the pathogenesis of several forms of cancer, e.g. leukemias, gastrointestinal stromal tumors and testicular tumors. Tumor
The large osmotic gradient over the outermost layer of human skin implies major structural changes along the gradient, which in turn affects transport. In particular, the possibility of phase changes introduces a non-linear element to the transport behaviour. We present a novel model membrane system to be used for studying these transport mechanisms, where we use a hydrophobic porous polymer membr
Transient receptor potential ankyrin 1 (TRPA1) is an ion channel involved in thermosensation and nociception. TRPA1 is activated by exogenous irritants and also by oxidants formed in inflammatory reactions. However, our understanding of its role in inflammation is limited. Here, we tested the hypothesis that TRPA1 is involved in acute inflammatory edema. The TRPA1 agonist allyl isothiocyanate (AIT
The demand for rare earth elements (REEs) is growing, while the future supply is uncertain. Their unique electronic characteristics make them irreplaceable, and the commercial value of pure fractions is high. A model-based simulation study is presented that compares batch chromatography with the twin-column MCSGP (multicolumn countercurrent solvent gradient purification) process for ion-exchange c
BACKGROUND: A horizontal gene transfer has brought an active nuclear gene, PgiC2, from a polyploid Poa species (P. palustris or a close relative) into the common grass sheep's fescue (Festuca ovina). The donor and the receptor species are strictly reproductively separated, and PgiC2 occurs in a polymorphic state within F. ovina. The active gene copy is normally closely linked to a very similar pse
This paper is intended to give an overview of clinically used imaging methods with special reference to digital techniques and 3D techniques for X-ray and nuclear medicine/molecular imaging such as CT, SPECT and PET. The paper will focus on recent advances and trends.
