Sensory traits shape animal lifestyles due to the central role they play in retrieving and processing environmental information. However, being some of the most energetically expensive tissues to build and maintain, ecological demands often modulate investment in these organs. Evidence that ecology shapes the evolution of sensory traits is plenty but is heavily biased towards vertebrates and has o
Carbon sequestration in arable soils is gaining increasing attention in global policymaking initiatives for climate-change mitigation. Large-scale assessments of soil organic carbon development in arable land are affected by the scarcity of reliable time series of soil organic carbon monitoring data and often fail to replicate observed trends or appreciate any effects induced by changes in soil ma
The advent of diffraction-limited storage rings (DLSRs) has boosted the brilliance or coherent flux by one to two orders of magnitude with respect to the previous generation. One consequence of this brilliance enhancement is an increase in the flux density or number of photons per unit of area and time, which opens new possibilities for the spatiotemporal resolution of X-ray imaging techniques. Th
To investigate whether coronary artery disease (CAD) burden is associated with plasma levels of the myocardial biomarkers Troponin I (TropI) and NT-proBNP in a large population-based sample using a cross-sectional design. Coronary computerized tomography (CT) angiography was performed in 25,859 subjects without a history of atherosclerotic disease from SCAPIS study (age 50-65, 52% women). TropI an
Popular Abstract in English The world’s resources of fossil fuels are rapidly being depleted, and we now know that the combustion of these fuels leads to the emission of greenhouse gases resulting in climate change. It is therefore imperative that we develop renewable sources of fuel. The production of bioethanol in Brazil is the best example today of the introduction of a renewable fuel on a largLignocellulosic biomass refers to plant material that is composed mainly of cellulose, hemicellulose and lignin. These materials are today of large interest to researchers in the field of biofuel and bioenergy. Residues for forestry and agriculture are particularly interesting since they result from crops with established cultivation procedures and technology for harvest and transportation are alr
Popular Abstract in Swedish Transportsektorn står för 63% av Sveriges använding av kol, olja och gas. Biobränslen som etanol, biodiesel och biogas står bara för 6.8% av energin som används för nationella transporter, biogas står för 12% av detta. Ökad produktion av biobränslen för transproter behöver inte betyda minskad produktion av jordbruks- och skogsråvaror för annat. Dels kan restprodukter anBiofuels are currently produced from agricultural crops, and an increasing use of crops for this application is expected in the EU in the years to come. The dominating crops cultivated in the EU for biofuel production today have a relatively large environmental impact. The European Energy Agency has identified several lignocellulosic crops, including industrial hemp, as more sustainable potential
The handling of biochemically functionalised beads or particles is becoming increasingly important in µTAS. Bead-based analysis of e.g. proteins can be made sensitive due to the large active surface area and flexible by chemical design of the bead surface. We have developed a microfluidic device utilising an array of integrated and individually controlled ultrasonic microtransducers for particle t
Tidigare forskning har visat att störda ätbeteenden (disordered eating/DE) är vanligt bland ungdomar, särskilt bland tonårsflickor. DE definieras som olika beteenden (t.ex. kräkningar, restriktivt ätande) och negativa attityder till ätande/kroppsform/utseende/vikt. Avhandlingen hade flera syften. (1) Att validera en svensk version av frågeformuläret RiBED-8 (risk behaviour for eating disorders) soPrevious research has described that disordered eating (DE) is common in adolescents, especially in girls. DE is defined as maladaptive behaviours (e.g., vomiting) and negative attitudes toward eating and one’s body shape, appearance, and weight. The present thesis had several aims. First, to validate a Swedish version of a Danish 8-item screening inventory, Risk Behaviour for Eating Disorders/RiB
Emotion regulation has been specifically linked to both non-suicidal self-injury (NSSI) and attempted suicide. It is also known that self-harm is disproportionally higher (30–68.4%) in forensic samples than in the general population, yet knowledge about the association between emotion regulation and self-harm in forensic settings is scarce. The purpose of this study was to describe emotion regulat
BACKGROUND: Biomarkers reflecting diverse pathophysiological pathways may play an important role in the pathogenesis of abdominal aortic aneurysm (aortic diameter ≥30 mm, AAA), levels of many biomarkers are elevated and correlated to aortic diameter among 65-year-old men undergoing ultrasound (US) screening for AAA.PROBANDS AND METHODS: To evaluate potential relationships between biomarkers and ao
Prospective clinical plasma biomarker studies in abdominal aortic aneurysm (AAA) pathogenesis have been hampered by the need for very large cohorts and long follow-up time. The main aim of the present study was to evaluate the association of adrenomedullin, a cardiovascular (CV) stress marker, and incident AAA risk. Prospective longitudinal cohort of middle-aged individuals from the CV cohort of t
ATT PLÖJA MYCKET, LITE ELLER INGET ALLS Vi blir fler och fler människor på vår planet, och år 2050 beräknas vi vara så många som 10 miljarder. Det innebär att vi måste kunna producera mer mat på en lika stor eller till och med mindre yta jämfört med idag. En stor del av den mat vi konsumerar produceras antingen direkt eller indirekt på åkrar runt om i världen. För lantbrukare som är inriktade på vSoil microorganisms are important for climate regulation as well as for plant nutrition. In agricultural soils the microorganisms are affected by management choices, like which type of tillage that is used. Moldboard plowing, the most common tillage practice, increases mineralization which leads to soil organic carbon (SOC) loss, and may thus reduce soil quality. Conservation tillage practices inf
At synchrotron light storage rings there is demand for serving high-brilliance users requesting multibunch operation while simultaneously serving timing users who require single-bunch operation. One method to accomplish this is PPRE developed and currently in user operation at BESSY II. In the method, the transverse emittance of one of the bunches in the bunch train is increased by an incoherent b
Catalytic processes have tremendous importance in our everyday life. Most chemicals, pharmaceuticals, plastics etc. are, in fact, produced with the help of catalysts. What is probably even more important is that the toxic wastes produced in great amounts by modern factories and plants are recycled or transformed into less poisonous substances by means of catalytic units. One example from our everyThe present work is devoted to atomic scale structural studies of the surfaces of model heterogeneous catalysts relevant to oxidation reactions. A novel approach using high-energy surface X-ray diffraction combined with mass-spectrometry measurements is employed to perform in situ structural characterization of Pd(100) and Pd(553) single crystal surfaces acting as catalysts in the process of CO ox
Rotary vacuum filters (RVFs) with adiatomaceous earth (kieselguhr) coatings as filter aid are the most established technology for the removal of the so-called mud fraction after liquefaction and saccharification in the production of starch-based sweeteners. The RVFs is an open process which is further associated with the use of filters resulting in an increasing disposal challenge. Based on this t
