Popular Abstract in Swedish Utveckling av AMS-systemet i Lund för detektion av 26Al – med tillämpningar inom växtekologin Den konventionella metoden för att mäta mängden radioaktivt material i ett prov är att detektera strålningen som kommer från provet. Om man vet halveringstiden (den tid det tar för mängen radioaktivt material minska till hälften) så kan man bestämma antalet radioaktiva atomer

This paper contributes to the debate as to whether or not Purchasing Power Parity (PPP) holds in the long run. This is done by looking at fractionally integrated processes (FIP) and using wavelets in order to obtain an Ordinary Least Squares (OLS) estimate of the long run memory parameter. Firstly, drawing on the theoretical framework behind PPP, this paper outlines the statistical background and

The goal of this research is to investigate how the use of provocative place branding, by companies, influences audience engagement with national identity, from a sensemaking perspective. The study specifically investigates how audiences, in the case of residents of Denmark, make sense of provocative content and how it influences their sense of place and national identity. The answered research qu

Rent dricksvatten är en mänsklig rättighet, men trots detta förlitar sig många människor i världen fortfarande på osäkra system för sin försörjning. Detta är särskilt ett problem i landsbygdsområden, som har en tendens att hamna på efterkälken när större satsningar görs inom vattenområdet. Vår studie undersöker vattenförsörjningen på landsbygden i södra Brasilien, och diskuterar utmaningarna som fAccess to clean drinking water is a human right and a necessity for life, yet many rely on precarious water sources across the world. The United Nations outlines a great aspiration in Agenda 2030 - that safe and affordable drinking water should be available for all by 2030. In Rio Grande do Sul (RS) in Brazil, more than one million residents rely on small-scale water supply solutions without conve

BACKGROUND: Trigger finger surgery typically has a successful outcome, also in patients with diabetes mellitus (DM). However, the impact of glycemic control on long-term outcomes after open trigger finger release (OTFR) remains unclear. This study examines whether high hemoglobin A1c (HbA1c) levels affect patient-reported outcome (PRO) following OTFR in individuals with type 1 diabetes mellitus (T

Popular Abstract in Swedish Avhandlingen är indelad i två delar. I den första delen studeras hur kommunikation påverkar utfall i strategiska situationer, så kallade spel. Den andra delen studerar individers riskpreferenser. Metodologiskt förlitar sig avhandlingen till största delen på ekonomiska experiment. I kapitel 2 till 4, som är författade tillsammans med Ola Andersson, studeras effekterna aThis thesis is divided into two distinct parts. The first part studies communication in games and the second part investigates individual decision making under risk. Chapters 2 – 4, co-authored with Ola Andersson, investigate communication and renegotiation in dynamic games. In Chapter 2, Bertrand supergames with non-binding communication are used to study price formation and stability of collus

Free radicals have been suggested to play a role in the development of diabetic retinopathy. The aim of the present study was to examine whether the metabolic perturbations caused by high-fat feeding of two strains of mice, the C57BL6/J mice and the NMRI mice, interfere with one of the free radical enzyme defense systems in the retina, i. e., glutathione (GSH), and whether morphological changes oc

The questions about why and how senescence occurs in the wild are among the most pertinent ones in evolutionary ecology. Telomere length is a commonly used marker for aging, while other biomarkers of aging have received considerably less attention. Here we studied how another potent indicator of aging-skin pentosidine concentration-relates to age and blood telomere length in a long-lived seabird w

This article studies the effect of alcohol consumption on the probability of long-term sickness-related absenteeism for women. Using Swedish matched survey and register data, we apply sample selection models to correct for nonrandom sampling into paid employment. There are three main findings of the study. First, diverging from the most prevalent consumption group (long-term light drinkers) is ass

Purpose We tested whether total prostate-specific antigen velocity (tPSAv) improves accuracy of a model using PSA level to predict long-term risk of prostate cancer diagnosis. Methods During 1974 to 1986 in a preventive medicine study in Sweden, 5,722 men aged <= 50 gave two blood samples about 6 years apart. We measured free (fPSA) and total PSA (tPSA) in archived plasma samples from 4,907 partic

The effects of operational and environmental variability have been posed as one of the biggest challenges to transit structural health monitoring (SHM) from research to practice. To deal with that, machine learning algorithms have been proposed to learn from experience based on a reference data set. These machine learning algorithms work well based on the premise that the basis of the reference da

In this thesis, the short- and long-term event study methodology are applied in order to assess whether M&As, in the pharmaceutical industry, create any abnormal return for the acquirer. The majority of the previous research finds a negative abnormal return but the short-term event study seems to generate slightly positive abnormal returns outside the U.S. There is a limited amount of research

Information about when and where animals die is important to understand population regulation. In migratory animals, mortality might occur not only during the stationary periods (e.g. breeding and wintering) but also during the migration seasons. However, the relative importance of population limiting factors during different periods of the year remains poorly understood, and previous studies main

Mantle cell lymphoma (MCL) is a heterogenic non-Hodgkin lymphoma entity, with a median survival of about 5 years. In 2008 we reported the early based on the median observation time of 4 years results of the Nordic Lymphoma Group MCL2 study of frontline intensive induction immunochemotherapy and autologous stem cell transplantation (ASCT), with more than 60% event-free survival at 5 years, and no s

The aim of this work was to assess whether or not oxidative stress had developed in a dwarf shrub bilberry (Vaccinium myrtillus L.) under long-term exposure to enhanced levels of ultraviolet-B (u.v.-B) radiation. The bilberry plants were exposed to increased u.v.-B representing a 15 stratospheric ozone depletion for seven full growing seasons (19911997) at Abisko, Swedish Lapland (68N). The oxidat

Single-stranded overhangs of the G-rich strand belong to the conserved features of telomeres composed of short telomeric repeats. These structures are thought to be essential for the maintenance of proper telomeric structure and function and the mechanism of their generation is telomerase-independent. We have examined the presence of single-stranded overhangs in Chironomus tentans, a dipteran inse

Nitrogen (N) deposition can enhance carbon (C) capture and storage in northern coniferous forests but it may also enhance the demand for phosphorus (P). While it is well established that long-term N enrichment can decrease decomposition and enhance the accumulation of C in soils, it remains uncertain if a higher demand and acquisition of P influence soil C. We studied microbial phosphorus mobiliza
