Geometrical Structure, Phase Diagrams, and Core-Level Binding Energiesof Metal Surfaces: Calculations, Simulations, and Experiments

Popular Abstract in Swedish Många fysiska egenskaper för ett material beror på den atomära strukturen, det vill säga vilka atomer som sitter var. För att bestämma den geometriska strukturen måste ofta en kombination av flera metoder användas. I detta arbete har vi använt högupplöst fotoelektronspektroskopi (HRCLS), diffraktion av lågenergetiska elektroner (LEED) samt beräkningar baserade på tätheThis thesis concerns clean and adsorbate covered metal surfaces and surface alloys. These systems have been studied using theoretical and experimental methods. In the first part of the thesis, the different techniques that have been utilized in this work are presented, and the included publications are summarized. The second part of the thesis consists of seven original publications. In the first

MicroRNA-Mediated Migration of Colon Cancer Cells

Colorectal cancer (CRC) is the second most common cancer in women and third most common cancer in men worldwide. The cause of the majority of death related to CRC is believed to be the migration of cancer cells to distant organs which is known as cancer metastasis. The mechanism behind cancer cell metastasis is not fully understood but accumulating studies suggest that it could be due to enhanced

α1-microglobulin – Therapeutic opportunities in kidney and erythrocyte pathology

Oxidative stress is defined as an imbalance between oxidants and antioxidants. The reasons behind the condition are diverse, and can result in, or contribute to, the severity of many diseases. The body has different protective mechanisms to reduce the oxidative burden, among them a protein called α1-microglobulin (A1M). A1M possesses a unique set of molecular properties enabling it to act as aradi

Resistance–recovery trade-off of soil microbial communities under altered rain regimes : An experimental test across European agroecosystems

With the increased occurrence of climate extremes, there is an urgent need to better understand how management strategies affect the capacity of the soil microbial community to maintain its ecosystem functions (e.g. nutrient cycling). To address this issue, intact monoliths were extracted from conventional and ecological managed grasslands in three countries across Europe and exposed under common

Technological Advancements in Affinity Proteomics : From planar antibody microarrays towards a solution-based platform

Abstract: Proteomics has the potential to deliver disease-associated biomarkers that could provide diagnostic, prognostic and predictive information to enable precision medicine. Affinity proteomics, most commonly based on antibodies and their ability to specifically capture target proteins, has emerged has a valuable tool in biomarker discovery. Our group has developed a recombinant antibody micr

One-year results of the SCANDIV randomized clinical trial of laparoscopic lavage versus primary resection for acute perforated diverticulitis

Background: Recent randomized trials demonstrated that laparoscopic lavage compared with resection for Hinchey III perforated diverticulitis was associated with similar mortality, less stoma formation but a higher rate of early reintervention. The aim of this study was to compare 1-year outcomes in patients who participated in the randomized Scandinavian Diverticulitis (SCANDIV) trial. Methods: Be

Design and Planning of a Transdisciplinary Investigation into Farmland Pollinators : Rationale, Co-Design, and Lessons Learned

To provide a complete portrayal of the multiple factors negatively impacting insects in agricultural landscapes it is necessary to assess the concurrent incidence, magnitude, and interactions among multiple stressors over substantial biogeographical scales. Trans-national ecological field investigations with wide-ranging stakeholders typically encounter numerous challenges during the design planni

Impact of ambient conditions on the Si isotope fractionation in marine pore fluids during early diagenesis

Benthic fluxes of dissolved silicon (Si) from sediments into the water column are driven by the dissolution of biogenic silica (bSiO2) and terrigenous Si minerals and modulated by the precipitation of authigenic Si phases. Each of these processes has a specific effect on the isotopic composition of silicon dissolved in sediment pore fluids, such that the determination of pore fluid 30Si values can

Increasing global ecosystem respiration between 1982 and 2015 from Earth observation-based modelling

Aim: Earth observation-based estimates of land–atmosphere exchange of carbon are essential for understanding the response of the terrestrial biosphere to climatic change and other anthropogenic forcing. Temperature, soil water content and gross primary production are the main drivers of ecosystem respiration (Reco), and the main aims of this study are to develop an Reco model driven by long-term g

Heavy metals in municipal solid waste deposits

Popular Abstract in Swedish Tungmetaller i kommunala avfallsupplagExtensive use of heavy metals in modern society influences routes followed by fluxes on the surface of the Earth. The changed flow paths may be harmful for the balance of biological systems at different levels, micro-organisms, human beings and whole ecosystems, since the toxicity of heavy metals is determined by their concentrations and chemical forms. The fluxes of cadmium in Sweden and especia

Health-related Quality of Life in Head and Neck Cancer. A Five-year Prospective Multicenter Study

Popular Abstract in Swedish Detta är en prospektiv longitudinell multicenterstudie som har haft som mål att utvärdera livskvaliteten (HRQL) hos patienter med cancer i huvudhalsregionen, vid diagnos, efter ett och fem år i relateration till tumörlokal, stadium, subsite, behand-ling, kön och ålder. Den första delen av studien, som varade i ett år, bestod av 357 patienter (medelålder 63 år; 72% män)

Phase separation, aggregation and gelation of a charged helixforming polysaccharide in aqueous salt solution

Popular Abstract in Swedish De senaste åren har jag ägnat åt att undersöka en speciell typ av gelbildare: kappa-carrageenan. Kappa-carrageenan kan användas för att göra gelé men används också i annan mat t.ex. efterrätter och glass, för att ge konsistens. När man vill göra en gel av kappa-carrageenan blandar man ut lite pulver i vatten och kokar sedan upp det hela. När blandningen kyls av kommer d

On the role of penicillin-binding protein SpoVD in endospore cortex assembly

Popular Abstract in English An endospore, which can be formed by some bacteria, is a dormant and extremely endurable state which helps the cell to survive long periods of harsh environmental conditions. The penicillin-binding protein SpoVD in Bacillus subtilis is essential for the synthesis of the endospore cortex, a protective layer consisting of modified peptidoglycan. In depth investigation of Bacteria of the genera Bacillus and Clostridium can form endospores as a strategy to survive unfavourable environmental conditions. Endospore formation involves synthesis of cortex, a thick layer of modified peptidoglycan that surrounds the spore. This layer is required for heat resistance of the spore and mutant spores lacking the cortex layer can be identified by a simple heat shock assay. B. su

Genetic organization of encapsulated and non-encapsulated Haemophilus influenzae strains. Analysis of the glpTQ and 23S rRNA operons

Encapsulated Haemophilus influenzae type b (Hib) and non-encapsulated H. influenzae (NTHi) are important pathogens causing invasive and mucosal infections in children. A 42 kDa surface-exposed lipoprotein, protein D, has been found to be a potential virulence factor of NTHi. The gene encoding protein D (hpd) is homologous to the glpQ gene encoding glycerophosphodiester phosphodiesterase in Escheri

To be able to explore different signal types and processing techniques, apt for sediment mapping, programmable, fully digital profiling systems has been built and tested. The systema are designed to be deployed also at small water depths from small boats, without special handling equipment. The usable frequency band is 100-25000 Hz, limited to approximately 2-10 kHz depending on the projector used

Bird orientation: external cues and ecological factors

Popular Abstract in Swedish Ett stort antal fåglar flyttar vår och höst mellan sina häckningsplatser hos oss i norr till “övervintringsområden”. Många flyttar över stora avstånd, till södra Europa eller till Afrika. Ofta är flyttfåglarnas mål väl definierat, det händer att en fågel häckar på exakt samma plats år efter år. Det finns observationer från t.ex. Afrika att fåglar kan vara lika trogna siBirds are generally capable of accurate orientation. In this thesis I present studies about the external cues and the ecological factors that influences bird orientation. A multitude of environmental cues are used to select and maintain a proper direction. These are visual cues, like the sun and the starry night sky, but other cues like the geomagnetic field, wind and odours also play important ro
