L-DOPA is currently the standard treatment for alleviating the motor symptoms in Parkinson's disease. The therapeutic efficacy, however, diminishes as the disease progresses. It has been suggested that the beneficial effect of L-DOPA could be reestablished by changing the mode of administration. Indeed, continuous delivery of L-DOPA has been shown to be an effective way to circumvent many of the s
We have measured the land-atmosphere CO2 exchange using the eddy covariance technique in a high Arctic tundra heath in northeast Greenland (Zackenberg). On the basis of 11 years of measurements (2000-2010), it was found that snow cover dynamics was important for the CO2 exchange. The start of CO2 uptake period correlated significantly with timing of snowmelt. Furthermore, for years with deep and l
Diagnostic DNA analysis using polymerase chain reaction (PCR) has become a valuable tool for rapid detection of biothreat agents. However, analysis is often challenging because of the limited size, quality, and purity of the biological target. Pre-PCR processing is an integrated concept in which the issues of analytical limit of detection and simplicity for automation are addressed in all steps le
Shrunken Pore Syndrome was recently suggested for the pathophysiologic state in patients characterized by an estimation of their glomerular filtration rate (GFR) based upon cystatin C, which is lower or equal to 60% of their estimated GFR based upon creatinine, i.e. when eGFRcystatin C ≤ 60% of eGFRcreatinine. Not only the cystatin C level, but also the levels of other low molecular mass proteins
Grass pollen allergens, including Phl p 5 from Phleum pratense, are major triggers of seasonal allergic rhinitis, primarily mediated by IgE antibodies. This study investigates the genetic basis and functional characteristics of IgG1 antibodies targeting Phl p 5, possibly derived from type 2 memory B cells predisposed to IgE switching. Using site-directed mutagenesis, we analyzed variants of a high
Human capital has been acknowledged as directly related to a firm’s performance. However, few researchers have analysed the influence of human capital and its degree of transferability into new venture development. This thesis aims to explore the phenomenon of individuals leaving careers in Small and Medium-sized Enterprises (SME) to establish new ventures. Specifically, this thesis aims to provid
WUI-NITY is a computer modelling program for wildfire evacuation simulations. This thesis examines the applicability of WUI-NITY to locations in Sweden. The program was tested at example locations representing the Swedish landscape. The objective of this work was both to examine the application of the model, but also to produce a process by which the model might be applied – highlighting challenge
I Sverige är bevisvärderingen fri, vilket innebär att den inte är bunden av legala regler. Vid bevisvärderingen använder sig domaren av vad lagstiftaren benämner allmänna erfarenhetssatser, som möjliggör att bevisningen kan sättas i en kontext. Erfarenhetssatser utgör en generalisering beträffande hur omständigheter vanligtvis förhåller sig till varandra och baseras på allmän bildning och livserfaIn Sweden, the evaluation of evidence is free which means it is not governed by legal rules. When evaluating evidence, the judge uses what the legislator refers to as common knowledge theorems (“allmänna erfarenhetssatser”), which enables the evidence to be put in context. Common knowledge theorems constitute generalizations about how circumstances usually relate to each other and are based on gen
The cumulative growth that the market of automobiles has seen since the end of the second world war, has had a major impact on both the way we plan our societies and in the way we live our lives. In Sweden from 1950 to 1960, car-ownership increased five-fold, making it the most car-dense country in Europe at the time – bringing along with it major car-centric urban renewal schemes, such as ‘Norrma

This project aimed to develop a vegan high-protein probiotic drink with two different tastes. The protein used should have similar quality as whey, amino acid score (AAS) 1.0. One aim was also to detect necessary processing steps. The protein sources studied for this application were oat, pea, pea+rice, hydrolyzed pea, soy, and potato. The protein sources were evaluated based on descriptive sensor
This thesis investigates particulate matter emissions from a turbofan jet engine operated with fossil Jet A fuel and mixtures of Jet A and sustainable aviation fuel (SAF), focusing on particle size distributions and total emission concentrations. The aim was to evaluate emissions from different fuel blends and sampling points, assess the performance of the designed sampling and dilution system, an
The field of general-purpose robotics has recently embraced powerful probabilistic diffusion-based models to learn the complex embodiment behaviours. However, existing models often come with significant trade-offs, namely high computational costs for inference and a fundamental inability to quantify output uncertainty. We introduce Normalizing Flows Policy (NF-P), a conditional normalizing flow-ba
Uppsatsen syftar till att undersöka sambandet mellan dagens situation på bolånemarknaden i Sverige och de ökade kapitaltäckningskraven för de svenska storbankerna. Utifrån syftet har en kvalitativ metod valts. Studien antar en deskriptiv karaktär, då den ämnar att beskriva sambandet mellan situationen på bolånemarknaden och de ökade kapitaltäckningskraven. Empirin bearbetas med en huvudsakligen dThe thesis aims to study the relationship between the current situation on the mortgage market in Sweden and raised capital requirements for the “big four” Swedish banks. Leading from the purpose a qualitative method has been chosen. The thesis assumes a descriptive nature, with the intention of describing the relationship between the mortgage market and raised capital requirements. The empirical
As more functionality and complex systems are combined in limited settings the need for resource management is becoming increasingly important. Resources such as computing capacity, battery power and communication channels need to be divided between different applications and hardware to achieve the highest global performance. Traditionally the computing capacity has been handled by the system sch
This master thesis was done in cooperation with the Danish district heating company, Vestegnens Kraftvarmeselskab I/S. VEKS is a transmission company supplying heat in western Copenhagen, Denmark. VEKS wanted a global analysis over the possibilities to decrease the cost and carbon dioxide emissions from purchased heat through decentralized accumulation. To cover all economical and environmental re
Popular Abstract in Swedish Pappersbrott i planet har studerats med hjälp av den kohesiva sprick modellen ur ett experimentellt såväl som ur ett teoretiskt perspektiv. Brott i en pappersremsa erhålls när remsan i en provmaskin belastas till sin maximala bärlast. Om remsan är tillräckligt kort fås en stabil nedåtgående last-förlängnigs kurva efter det att max lasten är nådd. Det visade sig att denThe in-plane failure of paper is studied in this work by means of a cohesive crack model from experimental as well as theoretical perspectives. Localized damage at in-plane tension of short paper strips is studied for low strain rates. It is observed that under uniaxial in-plane tensile tests, the evolution of the failure is stable and the damage of the paper strip is localized into a narrow zone
The European Union’s sugar policy is one of the most distorting policies within the common agricultural policy. It includes import control, production quota, and export refunds to support producer price within the EU at levels high above international prices. The main beneficiaries of the support system are the EU sugar industries and EU beet growers, but they are not the only producers benefiting
The enrichment of Fe, relative to alpha elements such as O and Mg, represents a potential means to measure the ages of quasi-stellar object (QSO) host galaxies and probe nucleosynthesis in the early universe. QSOs exhibit prominent Fe II features and Mg II 2800 angstrom resonance doublet emission in the ultraviolet. Although chemical evolutionary models predict that the Fe/Mg abundance ratio decre
Despite an abundance of peptides inside a cell, only a small fraction is ultimately presented by HLA-I on the cell surface. The presented peptides have HLA-I allomorph-specific motifs and are restricted in length. So far, detailed length studies have been limited to few allomorphs. Peptide-HLA-I (pHLA-I) complexes of different allomorphs are qualitatively and quantitatively influenced by tapasin t
