Background: A trial fibrillation (AF) is a common problem in pacemaker patients. We conducted a prospective observational study in patients paced for bradycardia with associated paroxysmal or persistent AF, to determine whether P-wave duration may stratify patients at higher risk for AF recurrences and AF-related hospitalizations. The patients were evaluated for the prevalence, cause, and predicto

Deactivation of SCR catalysts applied in bio fuel plants is a major problem due to higher amounts of potassium in bio fuel compared to other fuels. Regeneration of deactivated catalysts seems to be a promising way for minimising the total cost of bio fuel plants and great potential lies in finding regeneration processes that can be used commercially. The first applied regeneration method was washi

The Hartree-Fock-Bogoliubov (HFB) equation for deformed nuclei in a simplified model is solved in coordinate space with correct asymptotic boundary conditions, in order to study the pair correlation in nuclei close to the neutron drip line. The eigenphase formalism is applied, when the upper components of HFB radial wave functions are continuum wave functions. Calculated occupation probabilities o

Global regulatory circuits together with more specific local regulators play a notable role when cells are adapting to environmental changes. Lactococcus lactis is a lactic acid bacterium abundant in nature fermenting most mono- and disaccharides. Comparative genomics analysis of the operons encoding the proteins and enzymes crucial for catabolism of lactose, maltose and threhalose revealed an obv

I rapporten presenteras en brottmekanisk modell kallad Fictitious Crack Model, FCM, med vilken det är möjligt att beräkna sprickbildning i trä.

We review the ecology and distributions of the chafers Liocola marmorata (F.), Gnorimus nobilis (L.) and Gnorimus variabilis (L.) in Sweden based on museum and several large private collections. These species live in hollow deciduous trees, in Sweden especially in oaks. The former and recently documented localities are shown on maps. More than 100 years ago, all the species as well as their habita

Development and application of some laser techniques for the study of engine combustion are presented. The investigations mainly cover two aspects: fuel dynamics and formation of NO. Fuel dynamics is one of the most central problems in engine design since many performance parameters are affected by it; emission formation, efficiency, drivability etc. The studies include cycle-resolved measurement

We review the theoretical motivations and experimental status of searches for stable massive particles (SMPs) which could be sufficiently long-lived as to be directly detected at collider experiments. The discovery of such particles would address a number of important questions in modern physics including the origin and composition of dark matter in the universe and the unification of the fundamen

Family caregivers experience both positive and negative reactions in caregiving situations. There has been considerably less published about the positive aspects, however. The general aim of this study was to explore a previously developed instrument to study rewards gained by caregivers and to determine the factors associated with satisfaction in family members caring for patients with dementia l

In this report the moisture conditions and the moisture diffusivity of the concrete and its variations are estimated by computer calculations.

Det finns många situationer där data är hierarkiskt uppbyggda och där flernivåanalyser kan komma i fråga. Metoderna måste dock anpassas till frågeställningen, och modellerna måste kontrolleras mot data.

The chondroitin/dermatan sulfate proteoglycans (CS/DSPGs), biglycan, decorin, and versican play several important roles in extracellular matrix influencing matrix organization, cell proliferation, and recruitment. Moreover, they bind and regulate growth factors in the extracellular matrix. We have previously shown that cultured human lung fibroblasts treated with transforming growth factor-beta (T

Popular Abstract in Swedish En hjärtinfarkt definieras som celldöd i hjärtmuskeln, och om celldöden är omfattande, orsakar den en oåterkallelig nedsättning i hjärtats pumpfunktion. Pumpfunktionen kan även vara långvarigt nedsatt p.g.a. att hjärtat inte får tillräckligt med blod. Man kan då förbättra pumpfunktionen genom att återställa blodtillförseln med en operation. För att kunna hitta områden iThe assessment of ischemic heart disease (IHD) often focuses on the detection of dysfunctional but viable myocardium which may improve in function following revascularization. Dysfunctional but viable myocardium is identified by distinct characteristics with regards to function, perfusion and viability. Therefore, in Paper I we developed a method for quantitative polar representation of left ventr
