Purpose: Image-based computational fluid dynamics (CFD) is widely used to predict intracranial aneurysm wall shear stress (WSS), particularly with the goal of improving rupture risk assessment. Nevertheless, concern has been expressed over the variability of predicted WSS and inconsistent associations with rupture. Previous challenges, and studies from individual groups, have focused on individual

This study sets out to investigate the effect of the presence of small water-soluble additives on the tunability of the surfactant gel-to-liquid crystalline (Lß-La) phase transition temperature (Tm) for a bilayer-forming cationic surfactant and the phase behavior of such surfactant systems on dilution. This is strongly driven by the fact that this type of cationic surfactant has many interesting u

This paper sets up a framework for designing a massive multiple-input multiple-output (MIMO) testbed by investigating hardware and system-level requirements such as processing complexity, duplexing mode and frame structure. Taking these into account, a generic system and processing partitioning is proposed which allows flexible scaling and processing distribution onto a multitude of physically sep

Both genetic and lifestyle factors contribute to the risk of non-alcoholic steatohepatitis (NASH). Additionally, epigenetic modifications may also play a key role in the pathogenesis of NASH. We therefore investigated liver DNA methylation, as a marker for epigenetic alterations, in individuals with simple steatosis and NASH, and further tested if these alterations were associated with clinical ph

This paper looks at the problem of estimating the coefficients of a continuous-time transfer function given samples of its input and output data. We first prove that any nth-order continuous-time transfer function can be written as a fraction of the form /spl Sigma//sub k=0//sup n/b~/sub k/L/sub k/(s)//spl Sigma//sub k=0//sup n/a~/sub k/L/sub k/(s), where L/sub k/(s) denotes the continuous-time La

In May 2018, Google presented a new initiative called Digital wellbeing at their annual developer conference, Google I/O. Digital wellbeing consists of part a new design philosophy guiding the company’s products, part a set of tools to improve people’s relationship with digital technology. Using an STS influenced approach, this thesis seeks to better understand what role Google thinks technology s

Populärvetenskaplig beskrivning: Att veta hur olika saker i världen kom till hjälper en att släcka den törstiga sömn-förstörande nyfikenheten. Många har ställt sig frågan: hur skapades universum? Någorlunda hela svar har lagts fram (som till exempel teorin om Big Bang), men det finns mer att upptäcka. På en relativt mindre skala kan man fråga sig hur skapades Vintergatan? Ännu en fråga delvis svaradThe properties of the early Milky Way are quite mysterious and some are completely unknown even today. This study is the first one ever to analyze the mass distribution of Population III bulge stars. Using the fitting code STARFIT, we perform an analysis of 65 bulge metal-poor stars obtained by the EMBLA survey to estimate the IMF (initial mass function) of the very first stars that defined our ga

Den svenska avloppsvattenreningsprocessen består av flera olika steg som utnyttjar mekanisk, kemisk och biologisk rening för att avlägsna så mycket av ohälsosamma ämnen och organismer som möjligt från vattenomloppet. Avloppsvattenreningsprocesserna i Sverige saknar specifika reningsmetoder för vissa typer av organiskt material, såsom läkemedelsrester. Dessa mikroföroreningar bryts enbart delvis neThe Swedish wastewater treatment processes consists of multiple steps including mechanical, chemical, and biological cleaning to remove as much of the unhealthy substances and organisms as possible from the water circulation. The wastewater treatment process in Sweden lacks specific removal methods for some types of organic material, such as pharmaceutical residues and other microcontaminants. The

Minskade koldioxidutsläpp från energisektorn är nödvändigt om Sverige ska kunna nå klimatmålet inga net- toutsläpp av växthusgaser senast 2045. Biobaserad kraftvärme som drivs på restprodukter från skogsindustrin har möjligheten att bidra till minskade utsläpp men bränslena måste vara miljömässigt hållbara. Detta arbete undersöker potentialen för ett ökat uttag av grot, grenar och toppar, från sveReducing carbon dioxide emissions from the energy sector is essential if Sweden is to achieve its climate target of net-zero greenhouse gas emissions by 2045. Bio-based combined heat and power (CHP), fueled by residual products from the forest industry, has the potential to contribute to reduced emissions but only with enough fuel that’s environmentally sustainable. This study investigates the pot

This master’s thesis is a qualitative content analysis of nine municipal library plans (and two county library plans) with a basis in new institutionalism, specifically in regards to legitimacy, homogeneity as well as themes and patterns in the sourcematerial. With a basis in the history of the library plan and the municipal gouvernance, debate in regards to cultural policy, the downsizing of libr

Food waste represents major economic, social and sustainable challenges across the European Union, particularly within fresh fruit and vegetables (FFV). This study aims to quantify the amount of fresh food waste generated post-harvest for five FFV products i.e. avocados, bananas, cucumbers, eggplants and peppers (ABCEPs). This study will analyze and estimate the waste generated across 31 European

Even though animal farming is one of the leading causes of climate change and more people in the west are raising concerns over animal welfare, meat consumption here is high and expected to rise. This thesis examines the reasoning and tensions that arise when omnivores’ dietary choices clash with their love for animals by studying how the concept of the meat paradox and cognitive dissonance theory

Lactic acid fermentation has been a widely used process for many years, offering nutritional and sensory benefits to plant proteins. In this study, the objective was to produce a fermented pea powder with enhanced sensory properties by combining previous research from FrieslandCampina. A screening was performed on a set of cultures obtained from a contract research organization (CRO), starter Cult

It is a challenge to make ice cream without any dairy ingredients, since the components in dairy contribute to the unique flavour and structure of the ice cream. The aim with this project was to develop an ice cream mix containing only plant-based ingredients. The source of the main ingredient, the plant-base, was chosen by the company of which this project was requested by. The aim was to develop

Denna rapport är en utvärdering av brandskyddet med avseende på personsäkerheten i Lunds domkyrka. Lunds domkyrka uppfördes på 1100-talet och ligger i centrala Lund. I kyrkan hålls en mängd olika evenemang, vid stora evenemangen kan uppemot 950 personer vistas i kyrkan. Ett virtuellt platsbesök hölls med domkyrkokamrerare Mats Persson och Elisabet Nord som är ansvarig för vaktmästeriet den 25 marThe following report is an evaluation of human safety in Lund Cathedral with regards to a potential fire and evacuation. With the help of a virtual visit to the cathedral, pictures and statistics from The Swedish Civil Contingencies Agency (MSB), a general risk assessment was conducted in which possible fire- and evacuation scenarios were identified. A qualitative assessment of the probability and

Shifting between living places has become a common routine for many people all over the world. On the other hand, some people like students and commuting workers move only temporary, where the feeling of home and simplicity of moving to a new place might be challenged. The starting-point for this project was to investigate if objects can make it easier to move from place to place both emotion

Background and objective: There are multiple pharmacological treatment options for motor symptoms of Parkinson’s disease (PD). These comprise multiple drug classes which are approved for the condition, including levodopa, dopamine agonists, COMT inhibitors, MAO-B inhibitors, NMDA-receptor antagonists, anticholinergics, and others. Some of the drugs are approved for monotherapy and combination ther
