Wall-resolved large eddy simulations (LES) are performed to investigate turbulent heat transfer in a rough pipe over a range of Prandtl () numbers. The rough surface is generated using a controlled numerical procedure that allows independent specification of roughness correlation length, amplitude, and skewness; a statistically Gaussian height distribution is considered as a baseline case. The r
Syftet med denna uppsats är att utreda hur en förändring av det solidariska ansvaret för ungdomar hade överensstämt med skadeståndets övergripande funktioner. Anledningen till denna utredning är att Kronofogdemyndigheten och Barnombudsmannen påtalat att ungdomar i omfattande utsträckning drabbas negativt av att åläggas solidariskt skadeståndsansvar, och att en förändring av det solidariska ansvareThe purpose of this paper is to investigate how a change of joint responsibility for youths would correlate with the overall functions of tort law. The reason a change might be considered lies in a paper written by Kronofogdemyndigheten (Swedish state enforcement agency) and Barnombudsmannen (children's ombudsman) pointing out the negative economic effects the joint and several liability impos
This thesis deals with two main areas in the field of stochastic inventory theory; ateral transshipments and perishable items. In the first part of this thesis we give an introduction to the field of inventory theory, and discuss some previous literature connected to the research presented in this thesis. In the second part, the original research which defines this thesis is presented in the form

Popular Abstract in Swedish Det finns ett ökat intresse för behandling med talidomid. Därför var målsättningen med detta avhandlingsarbete att åstadkomma en mer ändamålsenlig användning. Några kemiska och farmakologiska aspekter med speciell inriktning på omsättningen av talidomid i människokroppen studerades. Historien om talidomid (Neurosedyn; varumärke i Sverige) är ett tragiskt kapitel i läkeThalidomide has a chiral center and the racemate of (+)-(R) and (-)-(S)-thalidomide was introduced as a hypnotic/sedative drug in 1957. In 1961 it was withdrawn due to teratogenicity and neuropathy. There is a growing interest in thalidomide treatment of immunomodulatory diseases. Given this renewed interest the aim of this thesis was to achieve a more rational use of thalidomide. Therefore some c
Popular Abstract in Swedish Min avhandling handlar om flyttning, det vill säga hur levande organismer rör sig mellan olika områden för att utnyttja resurser, undvika födobrist och som en anpassning till klimat- och miljöfaktorer. Vi begränsar det hela till fåglar's flyttning och bland dem ska vi koncentrera os's på rovfåglar. Rovfåglar är beroende av sina bytesdjur, som till exempel kan vara andraMy dissertation is about bird migration and addresses questions about how raptors adapt to the fluctuating environments during the transition seasons between breeding and wintering. The migration is highly affected by local prey abundance, foraging strategies, weather conditions and landscape patterns along the migration routes as well as navigation and orientation mechanisms and cues.

Radionuclide therapy requires patient-specific planning of the absorbed dose to target volumes, in most cases tumours, in order to achieve an expected biological effect, taking into account that the absorbed doses to normal organs and tissues should be kept as low as reasonably achievable. Therefore, the calculation of absorbed doses has to be as accurate as possible. The accuracy depends on the m
The fourth generation broadband (4GBB) concept aims for ubiquitous and high-speed data communication over the existing twisted copper pairs between the last distribution point and the customer premise equipment. Although it saves deployment cost for the last-mile communication, using the existing copper infrastructure makes the system vulnerable to crosstalk due to electro-magnetic coupling from t
Popular science summary: A growing body of evidence shows that tumors consist of rare cancer stem cells (CSCs), precursor cells and differentiated tumor cells. CSCs are today thought to be the main culprit in the tumor origin, progression, recurrence and resistance to therapy. The origin of CSC is enigmatic; however, it has been suggested that CSCs can arise from any type of cells and the underly
Popular Abstract in Swedish Fetma räknas som ett av världens tio viktigaste hälsoproblem enligt WHO och ökar i snabb takt. Man beräknar att över 1 miljard av världens vuxna befolkning är överviktig, d.v.s. har ett kroppsmasseindex (BMI) ?25.0 kg/m², varav 300 miljoner är feta, d.v.s. har ett BMI ?30.0 kg/m². I Sverige är 38% av kvinnor och 58% av män mellan 25 och 64 år överviktiga, och 11% respekThe aim of this thesis was to study the morbidity and mortality of cardiovascular disease (CVD) in obese individuals, as measured by different obesity measurements, and to explore how the CVD risk related to obesity was modified by other biologic and socio-demographic circumstances. Data from two population-based cohort studies was used. The Malmö Preventive Project included 22 444 middle-aged me
Haemophilia is a recessively inherited coagulation disorder, in which an X-chromosome mutation causes a deficiency of either coagulation factor VIII (FVIII) in haemophilia A, or factor IX (FIX) in haemophilia B. Intravenous administration of FVIII or FIX can be used to control a bleeding episode, to provide haemostasis during surgery or for long term prophylaxis of bleeding. In special cases, acti
The degradation kinetics of normal and branched chain butyrate and valerate are important in protein-fed anaerobic systems, as a number of amino acids degrade to these organic acids. Including activated and primary wastewater sludge digesters, the majority of full-scale systems digest feeds with a significant or major fraction of COD as protein. This study assesses the validity of using a common k

To ascertain whether a relationship exists between the PiZ alpha1‐antitrypsin (α1AT) variant and antineutrophil cytoplasm antibodies (ANCA)‐positive vasculitis in a large group of Swedish patients, and whether analysis for the presence of the PiZ variant might be useful for diagnostic or prognostic purposes.

This thesis deals with the development and application of new estimation approaches based on factor analysis for estimation and inference in dynamic panel data models with fixed-effects. A new factor analytical method (FA) for the estimation of fixed-effects dynamic panel data models is proposed in Bai ("Fixed-Effects Dynamic Panel Models, A Factor Analytical Method".

Popular Abstract in Swedish Nästan en miljon nya fall av magsäckscancer diagnostiseras årligen världen över. Även om frekvensen har fallit dramatiskt de senaste åren så är magsäckscancern fortfarande den näst vanligaste orsaken till död i cancer sett ur ett världsperspektiv. Den geografiska variationen av denna cancertyp är anmärkningsvärd med den högsta förekomsten i asiatiska länder såsom Japan,Nearly one million new cases of gastric cancer are diagnosed annually throughout the world. Even though the incidence has fallen dramatically in recent decades, this disease is still the second leading cause of cancer death in a global perspective. The geographic distribution of gastric cancer varies markedly, with the highest rates in Asian countries such as Japan, Korea, and China. This variatio
The main aim of my research is to unravel the origin and evolution of large spiral galaxies like our own Milky Way. This is best done by by probing and mapping in detail the age, chemical abundance, and kinematical properties of its main structural components. To do this I have utilised different tracers: dwarf stars in the solar neighbourhood, red giant stars in the inner and outer regions of the
