Police work may include performing repeated tasks under the influence of psychological stress, which can affect perceptual, cognitive and motor performance. However, it is largely unknown how repeatedly performing stressful tasks physically affect police officers in terms of heart rate and pupil diameter properties. Psychological stress is commonly assessed by monitoring the changes in these bioma
Since the earliest economic historical studies wage series have been used to sketch economic development both at the macro and the household level. This dissertation takes advantage of new data from women and men, working in both the countryside and in towns, as well as employed both by the day and on long-term contracts, in order to make an in-depth quantitative look at the relationships between
Hemiparasitic plants accumulate nutrients in their leaves and therefore produce high-quality litter with faster decomposition and nutrient release rates compared to non-parasitic litter. Higher levels of plant-available nitrogen (N) in the presence of hemiparasitic plants have been attributed to this 'litter effect', but effects on N dynamics in the soil remain unstudied. We tested the hypothesis
F-18-flutemetamol is a positron emission tomography (PET) tracer for in vivo amyloid imaging. The ability to classify amyloid scans in a binary manner as 'normal' versus 'Alzheimer-like', is of high clinical relevance. We evaluated whether a supervised machine learning technique, support vector machines (SVM), can replicate the assignments made by visual readers blind to the clinical diagnosis, wh
Astrocytes appear to be important mediators in the clearance of amyloid beta1-42 (A beta), the key component of senile plaques characteristic of Alzheimer's disease (AD). Recently, we found the amyloid associated proteins (AAPs) alpha 1-antichymotrypsin (ACT), apolipoprotein J and E (ApoJ and ApoE) and a mixture of serum amyloid P (SAP) and C1q (SAP-C1q) to modify A beta-uptake by human astrocytes
The Child Feeding Questionnaire (CFQ) assesses parental feeding attitudes, beliefs and practices concerned with child feeding and obesity proneness. While the questionnaire has been developed and primarily used in the U.S., validation studies in other countries are limited. The aim of this study was to examine the psychometric properties of the CFQ among mothers with preschoolers in Sweden and the

It only focuses on mechanical brakes by using two different brake pad material one is sintered, and another one is composite, in combination with grey cast iron brake disc. All the materials have been collected from real time braking operations from Green cargo. This research is an e
This study focuses on the estimation of lake water volume fluctuations using open-source remote sensing data and evaluates its accuracy. The research follows a three-step methodology, starting with water area estimation from Sentinel-2 imagery, followed by water level estimation using ICESat-2 satellite data, and concluding with the calculation of lake water volume differences, testing the regress
AimsWe recently identified a metabolic signature of three amino acids (tyrosine, phenylalanine, and isoleucine) that strongly predicts diabetes development. As novel modifiable targets for intervention are needed to meet the expected increase of cardiovascular disease (CVD) caused by the diabetes epidemic, we investigated whether this diabetes-predictive amino acid score (DM-AA score) predicts dev
Popular Abstract in Swedish Denna avhandling syftar till att belysa vilket professionskunnande som blivande lärare ges möjlighet att utveckla under sin högskoleförlagda utbildning och hur detta professionskunnande kan karaktäriseras. Detta belyses genom ett antal forskningsfrågor: Vilka olika undervisningspraktiker konstituerar den högskoleförlagda lärarutbildningen? På vilket sätt upprättas dessaThe starting point for this dissertation was the reform of the school system in Sweden with consequences for teachers´ work and new demands on their professional knowledge. This thesis aims to illuminate the issue of what professional knowledge student teachers are offered during their time in the university, and how this professional knowledge can be characterised. This is carried out with respec
Popular Abstract in Swedish Antikroppar är viktiga beståndsdelar av det naturliga immunförsvaret som skyddar oss mot smittämnen, såsom bakterier och virus. Utvecklingen av olika genetiska och biokemiska teknologier har dessutom möjliggjort användningen av antikroppar för en mängd ändmål, bl a för diagnostik och behandling av infektionssjukdomar och cancer. I denna avhandling, som bygger på fem vetAntibodies are key players of the immune system in higher vertebrates, which provide a defense against potentially lethal threats from the environment. Besides their importance in the immune defense, antibodies have a great potential as reagents in biological chemistry and diagnostics, and as therapeutic agents against both infectious diseases and cancer. Despite tremendous advances in all fields
The N-terminal RNA binding domain of U1A has been shown to fold in a two-state process without accumulating any intermediates. U1A has a symmetrically curved chevron plot which seems to result mainly from changes of the transition state. At low concentrations of denaturant the transition state occurs early in the folding reaction, whereas at high denaturant concentration it moves close to the nati
Popular Abstract in Swedish Avhandlingen är en studie av kvinnors brevskrivning i Sverige under 1700-talet. Breven är skrivna av ett antal kvinnor från de högre samhällsskikten (adel och borgerskap) under 1780- och 1790-talen. Flertalet av breven är skrivna på svenska, men några också på franska. Huvudsyftet med avhandlingen är att undersöka relationen mellan idén om att kvinnor skrev annorlunda, This dissertation is a study of women's letter-writing in eighteenth-century Sweden. The letters are written by a number of women from the uppper classes (nobility and bourgeoisie) during the last two decades of the eighteenth century. The majority of the letters are written in Swedish, some however in French. The main aim is to examine the relationship between the idea of women as a special kind
The dissertation can be divided into two parts, the first of which is a detailed analysis of three excavations concerning Mellanbyn in southern Malmö. In the second part I study the more general development of society, relating Mellanbyn to the surrounding area as well as to the region as a whole during Late Bronze Age and the Early Iron Age. The aim can be summed up as being to study the developm
The use of topographical data in hydrological and agricultural applications has increased with GPS data availability and the concept of precision agriculture. This thesis investigates the relationships between topography and in one case simulated soil moisture and in the other case yield. The yield was recorded with a new optical sensor, which uses a digital camera to detect objects and records th
Northern hemisphere peatlands play an important role in the global carbon (C) cycle, accounting for about 30% of global soil C and similar to 10-25% of global natural methane (CH4) emissions. Satellite remote sensing has the potential for extracting continuous information related to C exchange rates at regional and global extents, yet, few studies have focused on peatlands. In this study we examin
Background We aimed to accurately estimate the frequency of a hexanucleotide repeat expansion in C9orf72 that has been associated with a large proportion of cases of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). Methods We screened 4448 patients diagnosed with ALS (El Escorial criteria) and 1425 patients with FTD (Lund-Manchester criteria) from 17 regions worldwide for the
Popular Abstract in Swedish Hur kommer det sig att liknande reformprogram återfinns i olika länder? Varför väljs vissa idéer framför andra? Avhandlingen syftar till att öka förståelsen av så kallad policydiffusion, spridning av olika typer av policy, och den dynamik som omgärdar spridningen. Detta görs genom att undersöka hur externa, eller utländska, idéer integreras och översätts i en ny omgivniSimilar policies may be found in different countries. This, in turn, is an indication that policies travel. But why are certain policies imitated while others are not? The author seeks to further our understanding of policy diffusion and its dynamics by investigating how foreign ideas are integrated and translated into new contexts, and how these imported ideas influence national policymaking and
