An improved Volume of Fluid (VOF) method is presented which is applicable to high density ratio 3D flows for a large range of bubble Reynolds number (Re). The method is based on the Navier-Stokes equations for incompressible multi-phase flows which are discretized on a Cartesian staggered grid. The multi-grid technique together with the pressure-velocity coupling scheme for multi-phase flows have
Objective. Pancreatic pseudocyst is a common complication of both acute and chronic pancreatitis. The aim of the present study was to evaluate the efficacy and complications of different treatment regimens. Material and methods. All patients >= 15 years of age admitted to Lund University Hospital from 1994 to 2003 with pancreatic pseudocysts were analysed retrospectively. Pseudocysts were defined
Kriser är allmänna och problematiska inslag i samtida politik. Förstådd som en punkt i tiden då ordningen är underminerad av oordning och förändring medför krisen en normativ förskjutning som möjliggör extraordinära åtgärder och att krisen avgränsas från det normala, att det oförutsägbara kan avgränsas till krisen och det som görs i kriser kan anses sakna konsekvenser för normaliteten. AvhandlingeCrises are common and problematic features of contemporary politics. Thought as moments in time when order is undermined by flux and disorder, they entail a normative dislocation allowing for exceptional measures and for the bracketing off of crisis from normality, removing contingency from normality, and confining that done in crisis to crisis. This dissertation examines the concept of crisis in
The accuracy and precision of frameless neuronavigation as compared to conventional frame-based stereotaxy for implantation of deep brain stimulation (DBS) electrodes were studied in 14 patients with essential tremor. DBS electrodes were implanted bilaterally in the ventrolateral thalamus [ventrointermediate nucleus ( VIM)] in one procedure. Frameless neuronavigation was used on one side and the c
Popular Abstract in Swedish Statistik handlar om att beskriva slumpmässiga händelser. Genom att bygga matematiska modeller för hur slumpen beter sig kan man beräkna hur troliga olika händelser är. Skilda ämnen har nytta av olika slags slumpmodeller, men slumpens lagar är universella! Därför kan en slumpmodell som utvecklats inom ett ämne senare visa sig användbar inom ett helt annat.

The first part deals with the use of computationally effective lattice models for inference of data with a continuous spatial index. The fundamental idea is to approximate a Gaussian field with a Gaussian Markov random field (GMRF) on a lattice, and then to conduct a bilinear interpolation of this at non-lattice location
A reduced-order through-flow program has been developed at the Lund Institute of Technology. The goal of the work was to develop and verify a program suitable for scientific studies of coaxial turbines. The program has built-in capability for multiple choked stages, and turbine cooling, as well as flexible modules for state, losses, deviation, and blockage. The code uses Matlab [trademark] as a pl
This study analyze how the exploitation of agricultural land affects Sweden's ability to remain self-sufficient in grain, and the consequences that arise when agricultural land with the highest classification is disappearing the fastest. As the population increases the food production must also increase at the same pace. An important crops for Sweden's food supply is grain and it stands fo
Background: Well-established associations exist between the risk of small for gestational age (SGA) and unidimensional sociodemographic factors. We investigated social inequalities in SGA risk and adopted an intersectional approach that simultaneously considers different social categories. By doing so, we could assess heterogeneities in SGA risk within unidimensional sociodemographic categories. M
Background: Management of young febrile infants is challenging. Therefore, several guidelines have been developed over the last decades. However, knowledge regarding the impact of introducing guidelines for febrile infants is limited. We assessed the impact of and adherence to a novel guideline for managing febrile infants aged ≤59 days. Methods: This retrospective cross-sectional study was conduc
In-situ remediation through the injection of bioremediation fluids is becoming increasingly common for treating contaminated sites. Contaminants are targeted for treatment either directly at the source zone or through injections that form a permeable reactive barrier to prevent further transport of the contaminants. Commonly, multiple injections are performed in a grid covering an area of strategi
The impact of climate on the annual cycle and interannual variability of CO2 fluxes is assessed in European evergreen needleleaf forests (ENFs) and deciduous broadleaf forests (DBFs) using observations from 19 sites, alongside outputs from process-based and data-driven models. All models capture the temporal phasing of CO2 fluxes, including a shorter sequestration period in northern rather than so
The modern use of neoadjuvant and conversion systemic therapy in patients with colorectal cancer liver metastasis (CRLM) has improved resection rates and changed the borders between “resectable” and “unresectable” disease. Also, the use of preoperative systemic therapy has resulted in an increased frequency of disappearing liver metastasis (DLM). The optimal management of DLM is still controversia
Alkoholkonsumtion är vanligt förekommande bland vuxna, och över 80 procent i Sverige uppger att de dricker alkohol årligen. När alkoholkonsumtionen påverkar individens arbetsförmåga kan den medföra betydande risker för både säkerhet och arbetsmiljö. Höga krav ställs därför på arbetsgivaren. Via en rättsdogmatisk metod syftar uppsatsen till att analysera och jämföra arbetsgivarens ansvar vid alkoAlcohol consumption is common among adults, with more than 80 percent of individuals in Sweden reporting annual alcohol use. When alcohol consumption affects an employee´s work performance, it may result in safety risks and substantial impacts on the work environment. This results in further responsibilities and obligations for the employer. Using a legal-dogmatic method, this thesis aims to anal
With the rapid development of blood biomarkers (BBMs) related to amyloid-β (Aβ) pathology in Alzheimer's disease (AD), the question arises whether these can replace the accepted reference standard, positron emission tomography (PET), for assessing Aβ burden. BBMs can differentiate Aβ status reliably in cognitively impaired patients, but two-threshold strategies to further improve their performance
This paper seeks to determine whether factors related to autoimmunity risk remain significant after the initiation of two or more diabetes-related autoantibodies and continue to contribute to T1D risk among autoantibody positive children in The Environmental Determinants of Diabetes in the Young (TEDDY) study. Characteristics included are age at multiple autoantibody positivity, sex, selected high
Co-production has become paramount for scientists, practitioners and social groups of Indigenous peoples and local communities of rural and urban areas to deliver transformative changes that enhance sustainability. Co-production should result in knowledge that is credible, legitimate and usable to enable sustainable outcomes effectively. However, this is not always the case due to challenges relat
In the last years we have witnessed an increased number of experimental performances that engage with children. Shows made in collaboration and/or performed by children. Children on stage, children as our tour guides through cities, children leading us though darkness. There are many ways to analyze this ‘interest’ including curatorial schemes encouraging participation, funding agendas, institutio
Background and purpose: Various blood biomarkers reflecting brain amyloid-β (Aβ) load have recently been proposed with promising results. However, to date, no comparative study amongst blood biomarkers has been reported. Our objective was to examine the diagnostic performance and cost effectiveness of three blood biomarkers on the same cohort. Methods: Using the same cohort (n = 68), the performan
Background/Objectives: Artificial intelligence (AI) holds remarkable potential to improve care delivery in dermatology. End users (health professionals and general public) of AI-based Software as Medical Devices (SaMD) require relevant labelling information to ensure that these devices can be used appropriately. Currently, there are no clear minimum labelling requirements for dermatology AI-based
Background: Research on ethnic and socioeconomic treatment differences following in-hospital cardiac arrest (IHCA) largely draws on register data. Due to the correlational nature of such data, it cannot be concluded whether detected differences reflect treatment bias/discrimination – whereby otherwise identical patients are treated differently solely due to sociodemographic factors. To be able to
