This article evaluates whether the global dispersion of ventricular repolarization (DVR) can be estimated from measurements between a few adjacent or remote sites. Monophasic action potentials (MAP) were recorded from 61 +/- 18 left (LV) or right ventricular (RV) sites in 10 pigs and 44 +/- 16 LV, or RV sites in 8 patients by using the CARTO mapping system. MAP duration (MAPd) and end-of-repolariz
This study examines the long-run relationship between finance and economic growth in Sweden from the 1830s to the 1990s using recently developed econometric techniques for tests of cointegration. The role of investment, education and technological progress (patents) is accounted for as well in order to assess the relative importance of the development of the financial system for growth performance
The overall aim was to investigate informal caregivers providing care for older persons with dementia (≥ 65 years of age) in eight European countries. Focus was on their experiences of formal care, access to support and factors that were associated with caregivers’ psychological well-being and burden. Caregivers’ experiences of formal care were investigated in a qualitative study with four focus g
To further improve the flat-type loop heat pipe (LHP) performance, this study evaluates the practical potential of use of highly enhanced boiling structures. It is found that in our proposed new heat pipe (NHP) system, the working fluid from the evaporator outlet to the condenser inlet is in a liquid–vapor two phase flow, which is different from the classical LHP theory. A new P-T diagram is devel
Popular Abstract in English This thesis presents studies on moderately halophilic bacteria belonging to the family Halomonadaceae that accumulate polyhydroxybutyrate (PHB) in high amounts when grown under conditions of nitrogen limitation.

Spatially coupled low-density parity-check codes can be decoded using a graph-based message passing algorithm applied across the total length of the coupled graph. However, considering practical constraints on decoding latency and complexity, a sliding window decoding approach is normally preferred. In order to reduce decoding complexity compared with standard parallel decoding schedules, serial s
The chapter discusses some design challenges encountered when developing a conversational pedagogical agent. By tracing the historical roots of pedagogical agents in Intelligent Tutoring Systems (ITS), we discern central developments of creating an agent that is both knowledgeable and fosters a social relationship with the learner. Some main challenges when attempting to develop a pedagogical age
Popular Abstract in Swedish Bakgrund: Öroninflammation är vanligt förekommande i barnaåren. De flesta barn har haft minst en episod med akut varig öroninflammation (AOM) och/eller en period med vätska i mellanörat (SOM) före skolstart. De flesta får enstaka episoder, frekvensen av AOM avtar i 2-års åldern och frekvensen av SOM avtar före skolstart. Efter en AOM episod är det vanligt att man under Objective: Most preschool children have suffered from at least one episode of acute otitis media (AOM) and/or secretory otitis media (SOM). Some children have frequent AOM episodes and/or prolonged and recurrent episodes of secretory otitis media (SOM). The long-term out-come and sequelae are not fully clarified. Subjects and methods: Out of a birth cohort followed to the age of 3 years, 12 child
We present extensive density-functional theory (DFT) based calculations of the clean Rh(111) surface and of CO/Rh(111) overlayer systems. We study both ground-state structural properties and core-level shifts from differences in total energies at different coverages and adsorption sites. Most results are obtained using using norm-conserving or ultrasoft pseudopotentials. The overall reliability of
Popular Abstract in SwedishMånga skador och olägenheter av fukt kan uppkomma under en byggnads livslängd. De kan t.ex. orsaka hälsoproblem eller dålig ekonomi. För att minska fuktproblem kan en fuktdimensionering göras. I en fuktdimensionering behövs olika fuktberäkningar för att se hur fukttillståndet förväntas bli i eller på en yta av en konstruktion. Beräknade fukttillstånd används för att kontDetermination of the design conditions for moisture resistance requires in a Moisture Design number of different moisture calculations to be made in order to determine the moisture status within, or on the surface of, a structure. The objective of this work has been to ascertain how to allow for variations in climate data in order to be able to determine the most unfavourable moisture status likel
Abstract Question: Can satellite data be related to fine-scale species diversity and does the integrated use of field and satellite data provide information that can be used in the estimation of fine-scale species diversity in semi-natural grassland sites? Location: The Baltic Island of Oland (Sweden). Methods: Field work including the on-site description of 62 semi-natural grassland sites (repres
The key step in the reaction mechanism of multicopper oxidases (MCOs)-the cleavage of the O-O bond in O-2-has been investigated using combined quantum mechanical and molecular mechanical (QM/MM) methods. This process represents a reaction pathway from the peroxy intermediate after it accepts one electron from the nearby type-1 Cu site to the experimentally-observed native intermediate, which is th
The Covid-19 crisis has led to widespread impacts on society, not only in terms of high death tolls, but also in terms of cascading effects for essentially all societal sectors; especially due to all measures taken to reduce the spread of the disease. A range of actors have become involved in the response to the pandemic and to ensure appropriate actions being taken, these actors need good situati

The European Union's Natura 2000 (N2000) is among the largest international networks of protected areas. One of its aims is to secure the status of a predetermined set of (targeted) bird and butterfly species. However, nontarget species may also benefit from N2000. We evaluated how the terrestrial component of this network affects the abundance of nontargeted, more common bird and butterfly specie
Cross flow heat exchangers made from aluminum are common as radiators in vehicles. However, due to the increasing power requirement and the limited available space in vehicles, it is extremely difficult to increase the size of heat exchangers (HEXs) placed in the front of vehicles. Placing the heat exchanger on the roof or at the underbody of vehicles might offer opportunity to increase the size o
Abstract in UndeterminedRelevant source area of pollen (RSAP) and pollen productivity for 11 key taxa characteristic of the pasture woodland landscape of the Jura Mountains, Switzerland, were estimated using pollen assemblages from moss polsters at 20 sites. To obtain robust pollen productivity estimates (PPEs), we used vegetation survey data at a fine spatial-resolution (1 x 1 m(2)) and randomize
