Abstract in UndeterminedA numerical study has been performed to simulate the tip leakage flow and heat transfer on the first stage of a high-pressure turbine, which represents a modern gas turbine blade geometry. The low Re k-ω (SST) model is used to model the turbulence. Calculations are performed for both a flat and a squealer blade tip for three different tip gap clearances. The computations we
Temat “Retorik och lärande” fångar den pedagogiska dimensionen av retoriken som ett undervisningsämne. Historiskt har utgångspunkten varit de retoriska övningarna, progymnasmata. Min översättning av Afthonios progymnasmata publicerades 2002 under titeln Retoriska övningar. I mina kurser har vi återupptagit dessa övningar så att studenterna gradvis lär sig retorikens grunder. Övningsserien bygger p

Popular Abstract in Swedish Varje dag producerar vår kropp många miljarder nya blodceller. Dessa celler är livsnödvändiga för att många funktioner i kropp ska fungera. Exempelvis hjälper de till med att skydda oss från sjukdomar, läka skador, och med att transportera syre och avfallsämnen. Blodsystemet (det hematopoetiska systemet) är uppbyggt som en hierarki där hematopoetiska stamceller finns påIn the blood system, knowledge on the regulation of hematopoietic stem cells (HSCs) and their immature progeny has provided roadmaps of differentiation. Such information can also have a value to understand the etiology of hematological cancers, since clinical heterogeneity and prognostic therapeutic outcomes have been proposed to associate with the specific developmental stage from which the trans
It has often been argued that the Earth is like an island in space and that its brittleness is most clearly reflected on small islands in the oceans. Easter Island, in particular, with its largely depleted resources, has been seen as a microcosmic warning about what could happen to our entire planet. However, the analogy of the Earth and islands with finite natural resources is not self-evident fr
Klimatet förändras, och det är människans aktiviteter som är orsaken. Utsläpp av växthusgaser från fossila bränslen och ohållbar markanvändning på global, regional och lokal nivå driver den pågående uppvärmningen. Hur dessa drivkrafter utvecklas framöver avgör hur stora klimatförändringarna blir på sikt. Därmed återfinns klimatproblematikens orsaker, men även dess lösningar, i hur vi bygger och ut
When Diffusion Tensor Imaging (DTI) is used in clinical studies, statistical hypothesis testing is the standard approach to establish significant differences between groups, such as patients and healthy controls. However, diffusion tensors contain six degrees of freedom, and the most commonly used univariate tests reduce them to a single scalar, such as Fractional Anisotropy. Multivariate tests th
Denna avhandling är en sammanläggningsavhandling som består av tre enskilda forskningsartiklar som undersöker om och hur de inflytelserika åren, negativa händelser och kollektiva kriser påverkar social tillit – tron att dom flesta människor går att lita på. Trots det omfattande vetenskapliga intresset för social tillit, baseras större delen av tidigare forskning om hur social tillit formas över liThis dissertation is a compilation thesis comprised of three individual research articles that explore whether and how the impressionable years, detrimental events and collective crises predict social trust – the belief that most people can be trusted. Despite the widespread scholarly interest in social trust, most previous research in the formation of social trust over the life-course is based on
This paper presents a new control strategy for an underactuated two-link robot, called the Pendubot. The goal is to create stable oscillations of the outer link of the pendubot, which is not directly actuated. We exploit a recently proposed feedback control design strategy, based on motion planning via virtual holonomic constraints. This strategy is shown to be useful for design of regulators for
We study a class of radially symmetric Coulomb gas ensembles at inverse temperature β=2, for which the droplet consists of a number of concentric annuli, having at least one bounded “gap” G, i.e., a connected component of the complement of the droplet, which disconnects the droplet. Let n be the total number of particles. Among other things, we deduce fine asymptotics as n→∞ for the edge density a
We report a novel size-insensitive method, iso-acoustic focusing (IAF), that can, for the first time, analyze and separate cells based on their intrinsic acoustic properties. We characterize the IAF system using two different cell lines and apply it to measuring the acoustic impedance of two subgroups of white blood cells (WBC): neutrophils and lymphocytes. We find cell type specific differences i
On 18 August 2022, an extremely very local 45 minutes storm fell over Båstad. There are several observations close to or more than mm. In the summer 1937 there was a famous long-lasting rain, for which the daily value was 150 mm. During the summer 2007, there were many large rainstorms of around 75 mm. I compare the short-term 2022 storm with other large storms observed in Sweden, and I do the sam
Serier av dygnsnederbörd omfattande 89 år från Malmö, Halmstad och Göteborg har analyserats liksom dygnsnederbörd från 230 stationer i Skåne för perioden 1961–1990. Fördelning i rum och tid har undersökts liksomförhållanden mellan dygnsnederbörd och olika parametrar. Extremvärden har uppskattats med olika frekvensfördelningar. De allra största oberoende händelserna har inträffat ganska jämnt fördeSeries of daily precipitation including 89 years from Malmö, Halmstad and Göteborg have been analyzed aswell as daily precipitation from 230 stations in Skåne in the period 1961–1990. The distribution in space andtime has been investigated, and also the relation between daily rainfall and different parameters. The mostextreme independent events have occurred rather evenly distributed over Skåne, a
