To explore the global sequence and dispersion of repolarization of the right atrium, monophasic action potentials (MAPs) were sequentially recorded from the right atrium using an electroanatomical mapping (CARTO) system in 10 healthy pigs and in 10 patients with (n=6) and without (n=4) paroxysmal atrial fibrillation (PAF) during sinus rhythm, or using two MAP recording catheters in 30 patients wit

Bokens baksidestext: Fackligt medlemskap har länge varit självklart i det genomorganiserade Sverige. Så är det inte längre. Under de senaste femton åren har andelen fackligt anslutna fluktuerat betydligt kraftigare än tidigare, även om den svenska organisationsgraden fortfarande är mycket hög. Ett nytt fenomen är att allt fler nöjer sig med att bara tillhöra a-kassan. Utifrån en brett upplagd inte

Authentic tasks can promote higher-order learning. In the student task discussed in this paper the student teachers developed, tried, graded, discussed and revised mathematics test questions, in connection to an amusement park visit. The task was designed in an effort to bring the teacher educators in the mathematics and educational departments and those in the schools closer to each other through

Popular Abstract in Swedish Företeelserna handledning och lärande har en diffus innebörd i vardagliga sammanhang, såväl som i utbildningssammanhang. Individer uppfattar företeelser och ord på olika sätt. Man ger dem en mening utifrån sin erfarenhet eller brist på erfarenhet. Denna studie belyser den mening som en grupp sjuksköterskestuderande och deras handledande sjuksköterskor ger handledning, sSwedish nursing education has its roots within a tradition of vocational training in clinical practice. Supervision is commonly used in the practical parts of the education. The aim of the study was to explore, describe and understand the content and meaning of supervision expressed by student nurses and their supervisors. A complementary aim was to analyse and report on the research process as a

The effect of the electrodes on the early signal of the ionization sensor has been studied experimentally and with a model for the sensor. Experiments in a constant-volume combustion chamber with a generic electrode configuration allowed to investigate the role of electrode contact and the main path of the current. A framework for a model allowing the inclusion of electrode processes is introduced

Transfer of logistics knowledge to people can be carried out in a number of ways, in different directions and it can also take different forms from personal contacts in day-to-day work to longterm contracts between the parties. Cooperation is important in order to develop new knowledge. One of the innovations in the area is a "Virtual University" started by a consortium of universities in the Balt

The research described in this thesis has an interdisciplinary approach dealing with chemical, biological, and technical issues. One objective was to interface miniaturized liquid chromatography (LC) to mass spectrometry, i.e. MALDI-TOF MS and ESI-MS, in an unattended mode for high sensitivity determination of proteins and peptides. The coupling between capillary LC and MALDI was accomplished by e

Abstract. The essay aims at integration of different concepts of meaning developed in semiotics, biology, and cognitive science, in a way that permits the formulation of issues involving evolution and development. The concept of sign in semiotics, just like the notion of representation in cognitive science, have either been used so broadly as to become almost meaningless, or they have been outrigh

Abstract in UndeterminedA series of comprehensive large eddy simulations of non-premixed turbulent hydrocarbon flames of different sizes in a typical fire scenario have been carried out to compute the flame radiative heat transfer. In the simulation, considerations include the modelling of sub-grid turbulence, turbulent combustion, soot formation, thermal radiation and interactive heat transfer in
