Popular Abstract in Swedish Under de senaste 10 åren har antalet människor i Sverige som dör av akut hjärtinfarkt minskat stadigt. Den äldre befolkningen är dock växande och med ökande antal människor med fetma och typ II-diabetes, står vi inför en stor utmaning i framtiden vad gäller hantering av patienter med akut hjärtinfarkt. För att möta denna utmaning är det viktigt att öka vår förmåga att bOne of the major determinants of the final infarct size during an acute coronary occlusion is the size of the myocardium subjected to ischemia. Identification and quantification of this so-called myocardium at risk in the acute phase of ischemia has been difficult in patients with conventional methods, such as myocardial perfusion single-photon emission computed tomography (SPECT) or electrocardio

Animal personality has been widely documented across a range of species. The concept of personality is composed of individual behavioural consistency across time and between situations, and also behavioural trait correlations known as behavioural syndromes. Whilst many studies have now investigated the stability of individual personality traits, few have analysed the stability over time of entire

We investigate whether stellar-mass black holes have to receive natal kicks in order to explain the observed distribution of low-mass X-ray binaries containing black holes within our Galaxy. Such binaries are the product of binary evolution, where the massive primary has exploded forming a stellar-mass black hole, probably after a common envelope phase where the system contracted down to separatio

In this work, a first-order upwind and a high-order flux-limiter schemes for solving the advection–diffusion equation on unstructured grids were evaluated. The numerical schemes were implemented as a module of an unstructured two-dimensional depth-averaged circulation model for shallow lakes (IPH-UnTRIM2D), and they were applied to the Guaíba River in Brazil. Their performances were evaluated by c

A measurement setup for in situ sampling of internal relative humidity and temperature in concrete structures was developed. The setup was used to evaluate the moisture conditions and to determine whether drying of the concrete components within a nuclear reactor containment contributes to the moisture conditions. The measurement setup was tested for accuracy and thereafter installed in Swedish nu

Bacterial spores in a metabolically dormant state can survive long periods without nutrients under extreme environmental conditions. The molecular basis of spore dormancy is not well understood, but the distribution and physical state of water within the spore is thought to play an important role. Two scenarios have been proposed for the spore's core region, containing the DNA and most enzymes. In

Cultural transmission can increase the flexibility of behavior, such as bird song. Nevertheless, this flexibility often appears to be constrained, sometimes by preferences for learning certain traits over others, a phenomenon known as "biased" learning or transmission [1]. The sequential colonization of the Atlantic Islands by the chaffinch (Fringilla coelebs) [2] provides a unique model system in

OBJECTIVES: Previous studies have shown that patients with diabetes mellitus have an increased mortality after suffering from acute myocardial infarction (AMI). Patients with diabetes have several risk factors for cardiovascular disease. Our objective was to quantify the prevalence of pharmacological cardiovascular prevention at admission and relate such treatment to short and long-term mortality

PHENIX has measured the centrality dependence of charged hadron p(T) spectra from Au +An collisions at root(s)NN = 130 GeV The truncated mean p(T) decreases with centrality for p(T) > 2 GeV/c, indicating an apparent reduction of the contribution from hard scattering to high p(T) hadrdn production. For central collisions the yield at high p(T) is shown to be suppressed compared to binary nucleon-nu

We explore how the width of the three-pulse photon echo signal at long population times can be used to determine the strength of the system-bath interaction. Using simulation with finite pulses we show that a simple relation exist between the width of the echo signal, the coupling strength, and the pulse autocorrelation. The derived model is applied to Rhodamine 6G in alcoholic solution, a paradig

Antibody-based microarrays are among the novel classes of rapidly evolving proteomic technologies that holds great promise in biomedicine. Miniaturized microarrays (< 1 cm(2)) can be printed with thousands of individual antibodies carrying the desired specificities, and with biological sample (e.g., an entire proteome) added, virtually any specifically bound analytes can be detected. While consumi

Chemical signals are common in most crustacean social interactions and are often perceived via chemosensory (olfactory) organs on the first antenna. Intermolt courtship behaviors and mating were investigated in size-matched pairs of intermolt European lobsters (Homarus gammarus) where the olfactory receptors of either the male or the female were lesioned with distilled water (olfactory ablation) o

This paper addresses the question of bankruptcy and honesty in local contexts, and especially the problem of the bankrupt small businessman in conveying ‘honesty’ to the local community. Studying bankrupt entrepreneurs, the analysis explores a tacit dialogue between the failed businessmen and the small town communities where they live and work. The bankrupts respond to their seemingly mistrustful

Popular Abstract in Swedish Enkla kolväten och koldioxid är kemiskt stabila föreningar med mycket låg reaktivitet. På grund av en god råvarutillgång finns ett stort intresse för aktivering och omvandling av dessa föreningar till mer förädlade eller användbara produkter. Reaktioner som bryter starka intramolekylära bindningar är vanligtvis svåra att genomföra på grund av en alltför hög energibarriäAs the tridentate chelate complexes referred to as pincer complexes have expanded their scope as homogeneous catalysts, there is an increased interest in electronic and steric fine-tuning of such complexes. One accessible variable in this aspect is the hybridisation of any coordinated carbon atoms. This thesis describes the synthesis of bis(phosphine) and bis(phosphinite) PCP pincer complexes with

On the same stage is a case study showing the co-operation between amateurs and professionals in a play called Bara tusen korta år (Just a Thousand Short Years) by Alf Henrikson (1905-1995). Performances were given in the summers of 1994 ? 1998 in Huskvarna. The amateurs were from Huskvarna while the professionals were employed by the regional theatre in Jönköping. When investigating this project

The evolution of a system for the management of fatigue-related risks in airline and maintenance operations is at present a contentious issue. The aspirations for the integration of fatigue risk management processes into existing Safety Management System (SMS) guidelines need to be placed in the realities of the present economic and commercial environment – they therefore need to exhibit relevance

A method to determine the internal stress state across the grain of glued laminated wood (glulam), as well as the experimental equipment for measuring released deformation are described in this paper. The internal stress state is calculated from measured released deformations, which are measured by a contact free method based on a digital camera technique. Nondestructive measurement of the modulus
