The Helicobacter genus now consists of at least 26 species, with additional novel species in the process of being validated. Beyond the impact of H. pylori and human health, considerable research has focused on other Helicobacter species isolated from humans and animals and the associated natural diseases that range from subclinical inflammation to cancer in the gastrointestinal and hepatobiliary
Climate change and disasters are among today’s most pressing issues. The damage caused by the worldwide increase in disasters is staggering, with the urban poor being most at risk. Disasters make their already precarious living conditions worse, creating a vicious circle of poverty. More and more attention has thus been given to the need to address changing climatic conditions and disaster risk th
Empirical methods are important in software engineering. It is important to be able to evaluate new techniques and methods in a structured way before they are introduced in the software process. This paper presents how empirical methods may be taught by letting students take part in the execution and analysis of empirical investigations in projects. The projects that the students carry out include
The work described in this thesis represents a biophysical approach, mainly using nuclear magnetic resonance (NMR) spectroscopy, to investigate the impact of magnesium ions on the EF-hand calcium-binding proteins calmodulin and calbindin D9k, as well as the dynamics of these proteins at low calcium levels. The x-ray structure of magnesium-saturated calbindin D9k shows a magnesium ion in only one o
Popular Abstract in Swedish Avhandlingen är en studie av hur energianvändning och luftföroreningar i Polen, Estland, Lettland och Litauen har förändrats under övergången till marknadsekonomi efter 1989. Avhandlingen består av sex artiklar, vilka behandlar tre aspekter av dessa förändringar. I de tre första artiklarna analyseras energistrukturen i de baltiska länderna Artikel I) och Polen (ArtikelThis thesis is a study of how energy use and air pollution in Poland, Estonia, Latvia and Lithuania have been affected by the economic transition after 1989. It consists of six articles, which examine three different aspects of these changes. The first group of articles analyses the structure of energy use in the Baltic states (Article I) and Poland Articles II and III) at the outset of transitio
The purpose of this paper is to briefly discuss the rationale for using Student Response Systems (SRS) and to share our experience of using this teaching technology in a training session. Our experiences support existing pedagogical research and show that SRS can be used to transform traditionally passive lecture-based classes into stimulating, active learning environments. Students demonstrate be
A leaner organization of labour, outsourcing and new forms of employment imply significant changes. Politicians and private employers alike emphasize that it is the individual's responsibility to be 'employable'. In his influential discussion of flexible capitalism, Richard Sennett traces the concept of flexibility back to fifteenth-century English. Then it was used with reference to patterns of m
Popular Abstract in Swedish Avhandlingen består av tre essäer som behandlar effekterna av inkomplett information i de finansiella marknaderna. Av dessa essäer är två teoretiska och en är huvudsakligen empirisk. Samtliga essäer undersöker effekterna av parameterosäkerhet, och de använder sig av kontinuerliga modeller. Den första essän, "The Effect of Information Quality on Optimal Portfolio ChoiceThis thesis consists of three essays on incomplete information in financial markets, two of which are theoretical, and one that is mainly of an empirical nature. All three essays concern parameter uncertainty, and they employ a continuous-time framework. The first essay, "The Effect of Information Quality on Optimal Portfolio Choice," analyzes the portfolio choices made by three types of agents,
The tradition of writing books specifically for girls came to an abrupt end in the middle of the 1960's. In Sweden this was a turbulent decade when society changed in many ways, and equality between the sexes was a key word. The old girls' and boys' books were replaced by "the modern book for young people", which, it was proclaimed, should be up-to-date, discuss real problems, break taboos, and ap
The vascular-injuring amino acid homocysteine was previously shown to be increased in plasma in type 1 diabetic patients with clinical signs of nephropathy. Previous studies have also shown an inconsistent relationship between the development of diabetic nephropathy and retinopathy, indicating different pathogenetic mechanisms. In this study, plasma homocysteine was measured in 25 type 1 diabetic
The PHENIX experiment at RHIC has measured the invariant cross section for omega-meson production at midrapidity in the transverse momentum range 2.5 < p(T)< 9.25 GeV/c in p+p and d+Au collisions at root s(NN) = 200 GeV. Measurements in two decay channels (omega ->pi(0)pi(+)pi(-) and omega ->pi(0)gamma) yield consistent results, and the reconstructed omega mass agrees with the accepted value withi
I TV-programmet »Uppdrag granskning« påstods nyligen (16 mars 2004) att det är livsviktigt för patienter med akut hjärtinfarkt att bo i närheten av rätt sjukhus. Frågan är när geografiska skillnader i dödlighet blir så pass stora och säkra att de har betydelse för den enskilda patienten. När man studerar skillnader i dödlighet mellan olika sjukhus bör man om möjligt också beakta landstingens roll.It is a known fact that the 1990s brought a decrease in mortality after myocardial infarction in Sweden but that differences in mortality rates following myocardial infarction still remain between the Swedish counties. Unresolved, however, are questions as to what these inter-county differences mean for the individual patient and what role hospital care plays in this context. We analysed all patie
This thesis deals with flexibility in the design of real-time control systems. By dynamic resource scheduling it is possible to achieve on-line adaptability and increased control performance under resource constraints. The approach requires simulation tools for control and real-time systems co-design. One approach to achieve flexibility in the run-time scheduling of control tasks is feedback sched
