Popular Abstract in Swedish Kavitation uppstår när trycket är så lågt så att vätska övergår till gas och det är ett problem i många vattenkraftverk på grund av att det kan försämra turbinverkingsgraden samt skada närliggande fasta ytor. Denna avhandling behandlar de numeriska svårigheter som man måste komma tillrätta med för att kunna datorsimulera kavitation i vattenturbiner. Dessa beror på den tCavitation is a problem in many hydroelectric power plants since it can cause adverse effects on performance and damage to nearby solid surfaces. The concerns of this thesis are the numerical aspects of flow simulations in cavitating hydraulic turbines which contain several difficulties: turbulent and complex flows, steady and moving parts of the geometry, bubble transport and cavitation developme

In this thesis, we first consider the phenomenology of R-parity violating supersymmetric extensions of the Standard Model. Specifically, a large number of Lepton and Baryon Number violating decays of sparticles to particles are implemented in the Pythia event generator. The augmented generator has then been used to study event properties of these models, mainly at the LHC. During these studies, th

We recently reported that differential gene expression and DNA methylation profiles in blood leukocytes of apparently healthy smokers predicts with remarkable efficiency diseases and conditions known to be causally associated with smoking, suggesting that blood-based omic profiling of human populations may be useful for linking environmental exposures to potential health effects. Here we report on

The β-glucosidase TnBgl1A catalyses hydrolysis of O-linked terminal β-glycosidic bonds at the nonreducing end of glycosides/oligosaccharides. Enzymes with this specificity have potential in lignocellulose conversion (degrading cellobiose to glucose) and conversion of bioactive flavonoids (modification of glycosylation results in modulation of bioavailability). Previous work has shown TnBgl1A to hy

From the point of view of each individual’s sense-making, an organization is an emergent property of inter-individual sense-making processes and activities. The organization is a result of emergence from individual sense-making perspectives. A critically informed approach to research involves recognition / understanding of this emergence. Without the recognition of the uniqueness of each particula

The purpose of this thesis is double. First, it will be shown that a number of problems of the syntax of ancient, literary Italian lend themselves readily to an analysis in terms of the Theory of Principles and Parameters. Second, the Italian data, supported by comparative remarks on modern Romance and Germanic, confirm the essential correctness of one particular version of the above theory namely

The way the fuel is introduced into the combustion chamber is one of the most important parameters for the power output and the generation of emissions in the combustion of liquid fuels. The interaction beween the turbulent gas flow field and the liquid fuel droplets, the vaporisation of them and the mixing of the gaseous fuel with the ambient air that are vital parameters in the combustion proces

Background: The immunosuppressive effects of thiopurine drugs are mainly mediated through their intracellular metabolism into active 6-thioguanine nucleotide (6-TGN) metabolites, which are incorporated into DNA. Erythrocyte 6-TGN (E-6TGN) levels have been proposed as an instrument for monitoring treatment. The aim of the study was to use erythrocyte E-6TGN, methylated mercaptopurine (MeMP) metabol

Nematodes, rotifers and tardigrades were collected on three nunataks (mountain peaks penetrating the ice sheet) in Vestfjella, on six nunataks; in Heimefrontfjella and on the Schirmacher Oasis in East Antarctica in the austral summers of 1996/97 and 2001/02. Most samples were taken on the nunatak Basen in Vestfjella where the Swedish station Wasa is located. The microfauna was patchily distributed

Methanol is a genuine candidate on the alternative fuel market for internal combustion engines, especially within the heavy-duty transportation sector. Partially premixed combustion (PPC) engine concept, known for its high efficiency and low emission rates, can be promoted further with methanol fuel due to its unique thermo-physical properties. The low stoichiometric air to fuel ratio allows to ut

Shiga toxin (Stx), the unique virulence factor released by enterohemorrhagic Escherichia coli (EHEC), associated with gastrointestinal infection and in severe cases hemolytic uremic syndrome (HUS). Up until now, no effective therapies have been developed to control disease progression. In this thesis, four novel treatment strategies have been investigated targeting different aspects of EHEC pathog

The archaeological site of Fracción Mujular is composed of several small residential plaza groups and a monumental ballcourt located near the Pacific Coast of Chiapas, Mexico. Long known for the Central Mexican iconography found on its carved stelae (Navarrete 1976, 1986; García-Des Lauriers 2005, 2007, 2016; Taube 2000), the survey and excavations conducted during the course of this dissertation

This paper investigates the heat transfer on the outlet guide vane (OGV) surface and its endwall region. The Reynolds number is fixed at 300,000 and the flow is subsonic. The inlet flow angle is varied from +25°(on-design), to +40°and -25°(off-design). Experiments were conducted in a linear cascade test facility using thermochromic liquid crystal technique. Numerical simulations using RANS were ca

Aviation currently contributes about 3% of the world’s CO2 emissions, 5% of the global warming, and 35% of the trade. Reducing the emissions and the global warming from aviation is thus essential. Many approaches to achieve this goal are underway, including H2, fuel cells, and batteries, but also by replacing the fossil jet fuel with sustainable jet fuel from non-fossil feedstocks. This involves m

This thesis is about the (anti-)novel Den svarta solen (’The Black Sun’), one of the Swedish experimental author Lotta Lotass’ (b. 1964) most challenging works. It contains 340 texts, all describing different interiors in a monotonous and similar manner, which are arranged as a “Choose Your Own Adventure” gamebook. This turns the novel into a labyrinth, which the reader more or less literally can

Populärvetenskaplig sammanfattning: Det var en gång... historien om en vulkan. The Dunedin Volcano är belägen utmed östkusten på Nya Zeelands södra ö. Stora delar av både östkusten och de centrala delarna har under de senaste 40 miljoner åren upplevt perioder med intra platt vulkanism orsakad av en temperatur anomali i övre manteln under både Nya Zeelands Sydö och delar av havet öster om. VulkaneThe Portobello Peninsula is made up by volcanic sediments, lava flows and numerous dikes. Deposition of sediments and lava flows is thought be early in the evolution of the Dunedin Volcano. The lava flows of Portobello Peninsula are silica saturated, belonging to a lineage differing from the two major lineages previously inferred to exist in the volcano (Coombs and Wilkinson, 1969). This new linea
