A new method for QRST cancellation is presented for the analysis of atrial fibrillation in the surface electrocardiogram (ECG). The method is based on a spatiotemporal signal model which accounts for dynamic changes in QRS morphology caused, e.g., by variations in the electrical axis of the heart. Using simulated atrial fibrillation signals added to normal ECGs, the results show that the spatiotem

The purpose of the current study is to investigate the effect of particle-pair interaction for various separation distances and angular positions. The results obtained are used in a particle-laden turbulent jet flows in order to improve the existing Lagrangian Particle Tracking (LPT) models. In the first part, a detailed numerical study of particle interaction is carried out by varying the separa

This environmental audit report was completed after an environmental audit of the Baltijsk municipality in the District of Kaliningrad, Russia, during the 10th and 11th of April 2000. The report is a joint effort of 31 students from 23 countries, who are participants of the International Master’s Programme “Master of Science in Environmental Management and Policy ” at the International Institute

För att nå energimålen för bebyggelsen till 2020, uppsatta av EU och av den svenska regeringen, är det nödvändigt att inte bara minska energianvändningen i nybyggnader utan att även energieffektivisera befintlig bebyggelse. När renovering ändå genomförs finns stora möjligheter att utföra energibesparande åtgärder och på samma gång höja inomhuskomforten för de boende.

BACKGROUND: Hormone-sensitive lipase (HSL) is a key enzyme in the mobilization of energy in the form of fatty acids from intracellular stores of neutral lipids. The enzyme has been shown to exist in different isoforms with different molecular masses (84 kDa, 89 kDa and 117 kDa) expressed in a tissue-dependent manner, where the predominant 84 kDa form in adipocytes is the most extensively studied.

Aims. This paper is a report on a study exploring beliefs about health and illness in women with gestational diabetes born in Sweden and Africa living in Sweden. A further aim is to study the influence of beliefs on self-care and care seeking. Background. Extensive global migration leading to multicultural societies implies challenges to health care. Health/illness beliefs are culturally related a

BACKGROUND: Mortality caused by acute pancreatitis in patients admitted to the hospital has been thoroughly investigated, but knowledge regarding outpatient fatalities is far from complete. The purpose of this study was to assess the incidence and clinical characteristics of patients who have died due to acute pancreatitis occurring outside the hospital. METHODS: Deaths caused by acute pancreatiti

Firms proactive in environmental work and those pressured by their product chain have a list of restricted substances that they do not want their products to contain. But as environmental management issues progress, what are companies doing to reduce the use of these restricted substances? Brominated flame retardants used in cars, trucks and buses to improve fire safety are a rising public concern

BACKGROUND: /st> Previous studies have indicated that autoantibodies may be detected years before the clinical onset of rheumatoid arthritis (RA). Cartilage biomarkers, such as cartilage oligomeric matrix protein (COMP), have not been studied previously in samples collected before the diagnosis of RA. METHODS: /st> Between 1991 and 1996, 30 447 subjects were included in the Malmö Diet Cancer Study

The word plus(s) can function as a conjunction in Scandinavian, and as such coordinate for example embedded clauses introduced by the subjunction at(t). However, one can also find examples of clauses introduced by plus(s) at(t) although not preceded by another at(t)-clause. These constructions, which represent a relatively new development in Scandinavian, are semantically similar to coordinations

This paper presents a 90 nm CMOS A/D modulator operating with a supply voltage of 0.2 V, well below the threshold voltage of the transistors. The modulator is an open-loop first-order architecture based on a frequency-modulated intermediate signal, generated in a ring voltage-controlled oscillator. The linearity of the modulator is greatly improved by the adoption of a so-called soft-rail in the o
