Pion photo production from the nucleon is an important process utilized to understand the structure of the nucleon and the fundamental dynamics of the nucleon system. The neutral pion production has been extensively studied resulting in valuable data sets. However, much less data is available for charged pion photo production at energies below 200 MeV. In order to get a reliable data set for π+, f
In this thesis a deflation method for the Finite Pointset Method (FPM) is presented. FPM is a particle method based on Lagrangian coordinates to solve problems in fluid dynamics. A strong formulation of the occuring differential equations is produced by FPM, and the linear system of equations obtained by an implicit approach is solved by an iterative method such as BiCGSTAB. To improve the converg
Background: Irreversible electroporation (IRE) is a local tumor treatment. Thin needles are placed percutaneously around the tumor under ultrasound guidance. Short pulses of direct current sent through the tissue irreversibly increase cell membrane permeability leading to cell death. We report a phase I study assessing the safety of ultrasound guided percutaneous IRE in patients with localized pan
År 2011 infördes entreprenörskap i den svenska skolans läroplaner. På 1980-talet ansågs dock utbildningsorganisationen Ung Företagsamhet (UF), som fokuserar på entreprenörskapsutbildning för ungdomar, vara ideologiskt kontroversiell. Under loppet av 30 år har synen på entreprenörskap och UF:s status förändrats i grunden. Denna avhandling undersöker hur och varför entreprenörskap blev ett kunskapsoIn 2011, entrepreneurship was added to the curricula of Swedish schools at all levels. In the 1980s, however, the educational organization Junior Achievement (JA), that focuses on entrepreneurship education for young people, was considered ideologically controversial. Over the course of 30 years, the view of entrepreneurship and the status of JA has changed fundamentally. This thesis investigates
In an earlier study, we found that rice (Oryza sativa) grown in nutrient solution well-supplied with Zn preferentially took up light 64Zn over 66Zn, probably as a result of kinetic fractionation in membrane transport processes. Here, we measure isotope fractionation by rice in a submerged Zn-deficient soil with and without Zn fertilizer. We grew the same genotype as in the nutrient solution study
Popular Abstract in Swedish Den globala uppvärmningen av vår jord påverkar inte bara lufttemperaturen, utan även haven blir varmare. Dessutom förespås en ökning i nederbörd vilket kommer att göra havens ytvatten mindre salta. Temperaturförändringen och den ökade nederbörden kan leda till att skiktningen, den s.k. vertikala stratifieringen, som finns naturligt i haven blir skarpare och starkare. StIncreasing precipitation and surface water temperature due to global change may strengthen stratification in coastal regions, which could influence the behavior of dinoflagellate diel vertical migration (DVM). DVM is a behavioral mechanism by which dinoflagellates can access photosynthetically active radiation near the surface, and nutrients at depth. During this process, cells may need to cross b
This study investigates the interactions between a porcine lung surfactant (PLS) extract and distilled water, saline solution or Ringer solution. The phases which coexist in equilibrium with water or electrolyte solutions were analysed by X-ray diffraction and cryo transmission electron microscopy (cryo-TEM). A lamellar phase with a structure unit consisting of double bilayers was observed in wate
Popular Abstract in Swedish Jag har under min forskarutbildning vid Lunds tekniska högskola studerat proteiner med hjälp av en metod som kallas kärnmagnetisk resonans, NMR. I levande organismer regleras allt liv av tre typer av molekyler: DNA, RNA och proteiner. Den centrala dogmen i biokemi "DNA-RNA-Protein" innebär att den genetiska kod som ärvs i form av DNA och som finns i varje cell i kroppeThe general objective of the present thesis work was to examine 3-dimensional structure as well as the motional properties of two different types of two-domain proteins by solution-state NMR. One of the major tasks of this thesis work was to investigate the domain orientation of these molecules by employing residual dipolar couplings (RDC) which can be used as orientational restraints for increasi
Poly(ethylene glycol) monomethyl ethers (MPEG) were grafted on copolymers of maleic anhydride and styrene, methyl methacrylate, and ethylhexyl methacrylate, respectively. Hydrolysis of the remaining anhydride residues gave graft copolymers carrying a large number of carboxylic acid groups along the main chains. The properties in aqueous solutions of these graft copolymers were studied with respect
Abstract An N-Heptane mechanism and a Methane/Propane mechanism have been reduced by an Automatic Reduction Tool (ART) and simulated with two different solver combinations, which solve the set of ordinary differential equations governing the time evolution of the species simultaneously with solving algebraic equations for species that can be considered to be in quasi steady state. The most succes
Firms proactive in environmental work and those pressured by their product chain have a list of restricted substances that they do not want their products to contain. But as environmental management issues progress, what are companies doing to reduce the use of these restricted substances? Brominated flame retardants used in cars, trucks and buses to improve fire safety are a rising public concern
In this study, a mathematical model was developed to simulate the jet and plume behavior in order to determine the optimum discharge conditions for different scenarios. The model was divided into two sub-models, describing respectively the near and intermediate field properties of the discharge for different inclinations and bottom slope. The lateral spreading and electrical conductivity was also

Background: Swirl sign has previously been described in epidural hematomas as areas of low attenuation, radiolucency or irregular density. The aims of this study were to describe swirl sign in ICH, study its prevalence, study the reliability of the subjective evaluation on computed tomography (CT), and to explore its prognostic value. Methods: CTs of 203 patients with ICH were retrospectively eval
Purpose: To what extent active surveillance and deferred treatment for localized risk prostate cancer are used is unclear. We assessed the use of surveillance and of deferred treatment in a population based, nationwide cohort in Sweden. Materials and Methods: In the National Prostate Cancer Register of Sweden, with a 98% coverage vs the compulsory Swedish Cancer Registry, we identified 8,304 incid
