This paper describes the development and performance of a new rapid amperometric biosensor for fructose monitoring in food analysis. The biosensor is based on the activity of fructose dehydrogenase (FDH) immobilised into a carbon nanotube paste electrode according to two different procedures. The direct wiring of the FDH in a highly original osmium-polymer hydrogel was found to offer a better enzy
We present an investigation on the effect of inter-micellar connections (branches) on the rheology of wormlike micelles. The system chosen is made of lecithin, minute amounts of water and organic solvents. Lecithin and water self-assemble into wormlike reverse micelles that can be branched or unbranched depending on the oil composition (and on the water content). In this respect, cyclohexane favou
Den rådande rättspolitiska debatten avseende omedelbarhetsprincipen och dess behov av reform har lett till ett flertal offentliga utredningar och propositioner. Dessa förslag har under uppsatsskrivandets gång resulterat i lagändringar medförande att tidiga förhör får åberopas som bevis i domstol. Syftet med denna framställning är att med avstamp i förarbetena till 1948 års rättegångsbalk göra en jThe current legal policy debate regarding the principle of immediacy and its needs for reform has led to several Swedish Government Official Reports and government bills. During the writing of this essay, these proposals have resulted in amendment of an act; early non-public hearings may now be plead as evidence in court. The purpose of this thesis is to make a comparison between corresponding arg
Abstract in UndeterminedSpatial data clearinghouses are one of the key features of a spatial data infrastructure (SDI). However, recent research indicates that few national clearinghouses function well, as the spatial data resources available cannot be satisfactorily accessed or optimally used. To improve the functionality, we propose that clearinghouses to be complemented with expert systems and
The intensive use of nano-sized titanium dioxide (TiO2) particles in many different applications necessitates studies on their risk assessment as there are still open questions on their safe handling and utilization. For reliable risk assessment, the interaction of TiO2 nanoparticles (NP) with biological systems ideally needs to be investigated using physico-chemically uniform and well-characteriz
The aim of this university paper was to understand how eight former clients at Staple reformatory had experienced their stay there. The clients at Staple are young people between 13-20 years old, both boys and girls. The basic questions were: What picture do the clients have of the treatment they received? What has been, from their perspective, the most important during their stay? Do the client
In the 1930s, a boat-grave was found in Sutton Hoo, England. Soon after, it was noted to have several similarities to swedish boat-grave from the region of Mälardalen, specifically Vendel and Valsgärde. These graves are from the same period as the Sutton Hoo ship burial, in Sweden known as the Vendel period (550-750 AD). Since then there has been an ongoing discussion concerning how the Sutton Hoo
In a phase of instability during the dynamical evolution of some multiple exoplanetary systems, exchange of angular momentum and/or energy through gravitational interactions between planets will lead to alterations of their orbital properties. In some cases, planetary orbits end up crossing, which leads to close encounters between two planets. In turn, they undergo a planet--planet scattering even
The discussion about weather one should pay expensive management fees to let professionals manage your money or if one should simply invest in an almost costless index fund has been going on for decades. This study’s objective is to investigate if the most popular actively managed mutual funds in Sweden can outperform the most popular Swedish passive broad market index fund. The study analyzes 62

Insects play a major role in the ecosystem and are an important factor for biodiversity. Using laser remote sensing to distinguish and monitor the millions of insects in-situ, holds large potential to speed up and improve the otherwise time consuming process of trapping and subsequent analysis. In this work, the spectral analyser for an elastic hyper spectral lidar in the SWIR, with 64 effective s
Botswana’s reputation as a beacon of fiscal prudence in resource-rich economies faces new challenges. Yet recent pressures – rising debt, declining surpluses, and fiscal volatility – raise questions about the long-term sustainability of this model. This thesis examines how Botswana’s fiscal capacity has shaped its ability to manage natural resource wealth between 1990 and 2022. Drawing on a compos
Estimating glomerular filtration rate (GFR) is important in daily practice to assess kidney function and adapting the best clinical care of patients with and without chronic kidney disease. The new creatinine-based European Kidney Function Consortium (EKFC) equation is used to estimate GFR. This equation was developed and validated mainly in European individuals and based on a rescaled creatinine,
Iron centeredN-heterocyclic carbene (Fe-NHC) complexes have shown long-lived excited states with charge transfer character useful for light harvesting applications. Understanding the nature of the metal-ligand bond is of fundamental importance to rationally tailor the properties of transition metal complexes. The high-energy-resolution fluorescence detected X-ray absorption near edge structure (HE
The CKD-EPI creatinine-based estimation equation for glomerular filtration rate (GFR) cannot be used in children, overestimates GFR in young adults, and its combination with the KDIGO recommended pediatric CKiD (Schwartz bedside) equation causes implausible increases in estimated GFR when switching from pediatric to adult care. By establishing sex-specific creatinine growth curves for children and
