During 2000 and 2001, an outbreak of human salmonellosis occurred in Sweden and Norway, caused by Salmonella livingstone. In this study, the genotypic differences between three strains obtained from food sources during the outbreak, two human strains and 27 more or less unrelated strains were analysed, using the three methods; automated ribotyping, pulsed field get electrophoresis (PFGE) and rando
Recent Hubble Space Telescope observations of a large sample of globular clusters reveal that every cluster contains between 40 and 400 blue stragglers.The population does not correlate with either stellar collision rate (as would be expected if all blue stragglers were formed via collisions) or total mass (as would be expected if all blue stragglers were formed via the unhindered evolution of a s
BACKGROUND: Legumes are one of the most common foods causing allergic reactions in children and adults. Cross-reacting antibodies are frequently demonstrated in this family but the real clinical cross-reactivity is uncommon. OBJECTIVE: To report a case of lupine-induced anaphylaxis and to elucidate in vivo and in vitro cross-reactivity with some legumes. METHODS: Skin prick test (SPT) with some le
The diurnal and vertical variability of heat and carbon dioxide (CO2) in the atmospheric surface layer are studied by analyzing measurements from a 213 m tower in Cabauw (Netherlands). Observations of thermodynamic variables and CO2 mixing ratio as well as vertical profiles of the turbulent fluxes are used to retrieve the contribution of the budget terms in the scalar conservation equation. On the
Popular Abstract in Swedish Fysiologisk integrering och morfologisk plasiticitet i stora klonala växter Många av våra vanligaste växter är klonala, dvs de kan producera avkommor utan sexuell befruktning. Hit räknas blåbär och lingon, många av våra vårväxter som tex. vitsippa och flera av våra värsta ogräs, som kvickrot och kirskål. En fördel som klonala växter har är att dotterskott som fortsätteClonal plants show a large variation in physiological integration, i.e. the translocation of resources among ramets within the clone. As resource transport is costly, we hypothesized that plants from poor sites should be more highly integrated than plants from rich sites and that plants would benefit if they were plastic in their degree of integration. Tracers were used to study the transport of w
In this paper we present analytical expressions for the angle-of-arrival (AOA) power density function (PDF) and its application in geometrically based channel models for urban environments. We make comparisons with experimental results for wideband channel models, published in the open literature, in order to evaluate the theoretical clusters PDF in angle domain proposed. The comparison with exper
Surrogate indicators are meant to be alternatives or complements of safety analyses based on accident records. These indicators are used to study critical traffic events that occur more frequently, making such incidents easier to analyse. This article provides an overview of existing surrogate indicators and specifically focuses on their merit for the analyses of vulnerable road users and the exte
In the framework of robotics, Reinforcement Learning (RL) deals with the learning of a task by the robot itself. This paper presents a hierarchical planning approach in which the robot learns the optimal behavior for different levels. For high-level discrete actions, Q-learning was chosen, whereas for the low level we utilize Policy Improvement with Path Integrals (PI^2) algorithm to learn the par
We describe the dynamical evolution of a unique type of dark star cluster model in which the majority of the cluster mass at Hubble time is dominated by an intermediate-mass black hole (IMBH). We analysed results from about 2000 star cluster models (Survey Database I) simulated using the Monte Carlo code MOnte Carlo Cluster simulAtor and identified these dark star cluster models. Taking one of the

The analysis of annual extremes of hydrological and meteorological variables is frequently complicated by the presence of gaps in record, and when records are not only fragmented but also short, it is necessary to utilize to the full the information contained in them. One method is to abstract for statistical analysis all extreme events whose peaks exceed a pre-selected threshold value, but the th
BACKGROUND: Septic shock may cause splanchnic hypoperfusion. We hypothesized that levosimendan would improve systemic and hepatosplanchnic perfusion during endotoxemic shock. METHODS: In 16 anesthetized pigs (31.4 +/- 3.4 kg), a jugular vein, a carotid artery, the Pulmonary artery (thermodilution), the portal vein, and a hepatic vein were cannulated for hemodynamic monitoring and blood sampling. U
I denna artikel tar jag upp ett berättargrepp, den narrativa syllepsen, som inte fått någon större uppmärksamhet i litteraturteorin hittills. Den narrativa syllepsen definierades först av den franske litteraturteoretikern Gérard Genette år 1972 som ett berättargrepp där olika temporaliteter smälter samman. Begreppet har dock inte använts i någon större utsträckning därefter, vilket jag anser vara In this article I discuss a narrative device, the narrative syllepsis, which has not received much attention in literary theory until now. The narrative syllepsis was first defined by French literary theorist Gérard Genette as a narrative device where different temporalities merge. The concept has however not been used att a larger scale after Genette, something I find surprising taking into consi
