The goal of this paper is to determine whether the photoplethysmography (PPG) can replace the ECG-based detection of heart rate turbulence. Using the PPG, classification of ventricular premature beats (VPBs) is accomplished with a linear classifier. The two conventional parameters turbulence onset and slope are studied together with a recently introduced parameter characterizing turbulence shape.
Background: Studies on leisure time physical activity as risk factor or protective factor for knee or hip osteoarthritis (OA) show divergent results. Longitudinal prospective studies are needed to clarify the association of physical activity with future OA. The aim was to explore in a prospective population-based cohort study the influence of leisure time physical activity on severe knee or hip OA
Internationally there is an on-going political struggle regarding whether to define prostitution as violence, sex or work. In Sweden, however, the national law that bans purchase of sexual services, by defining prostitution as violence against women, has strong support. The aim of this article is to identify and describe claims-making and mobilisation on the Internet against Swedish prostitution p
Popular Abstract in Swedish Bakterier är små encelliga organismer som lever i nästan varje tänkbar miljö på jorden, inklusive i och på människor. Vi är kontinuerligt koloniserade av bakterier i bland annat våra luftvägar, munhålor och mag-tarmkanaler. Denna samexistens är oftast ömsesidigt fördelaktig, eller åtminstone ofarlig för oss människor, och det är känt att bakterier hjälper oss bryta ner Nontypeable Haemophilus influenzae (NTHi) is a remarkably proficient colonizer of the human respiratory tract. The aim of this thesis has been to characterize currently known, and identify novel, bacterial factors involved in the key processes of colonization and pathogenesis, namely adherence to host tissue and evasion of the host innate immunity. We have shown that the NTHi virulence factor Pr
Measurement of cortisol concentration can contribute important information about an individual's ability to adjust to various environmental demands of both physical and psychosocial origin. However, one uncertainty that affects the possibilities of correctly interpreting and designing field studies is the lack of observations of the impact of seasonal changes on cortisol excretion. For this reason
I denna studie visar vi olika fördelar med vår e-learning-modell, som har „räddat” småspråket rumänska. Vi konstaterar dessutom att denna utbildningsmodell kan tillämpas på vilket annat språk som helst, för att uppnå ett flexibelt, rationellt, kostnadseffektivt och modernt lärande.
Multi-storey wood buildings have been increasing in popularity since a century-old ban on the construction of such buildings was lifted in 1994. Compared to conventional concrete structures, it is more difficult to build lightweight structures in such a way that noise and disturbing vibrations is avoided. To design buildings of high performance regarding sound and vibrations, it is desirable to ha
In this very short paper, I argue that it is possible to harmonize the doctrine of original sin, as western Christendom has traditionally understood it, with a polygenist account of human ancestry. To this end, particular attention is paid to the encyclical Humani Generis (1950), in which Pope Pius XII strongly cautions against polygenist ideas.
A candidate for chiral bands was found in Tl-198 for the first time in a mass region of oblate (or nonaxial with gamma >= 30 degrees) deformed nuclei. Two bands show very similar quasiparticle alignments, moments of inertia, and B(M1)/B(E2) ratios. They have a relative excitation energy of about 500 keV and different patterns of energy staggering. Calculations using the two-quasiparticle-plus-tria
This paper is the follow up of a previous work and its target is to demonstrate that the best fuel for a Compression Ignition engine has to be with high Octane Number. An advanced injection strategy was designed in order to run Gasoline in a CI engine. At high load it consisted in injecting 54 % of the fuel very early in the pilot and the remaining around TDC; the second injection is used as ignit
Laminar burning velocities for methanol, ethanol, and binary and quaternary mixtures of these with isooctane and n-heptane, have been determined using the heat flux method on a flat flame adiabatic burner. Measurements were done for an equivalence ratio range between 0.7 and 1.5 and for a range of temperatures between 298 K and 358 K at atmospheric pressure. The present study expands the available
Background and purpose With an aging population expecting an active life after retirement, patients' expectations of improvement after surgery are also increasing. We analyzed the relationship between preoperative expectations and postoperative satisfaction and self-reported outcomes with regard to pain and physical function after knee arthroplasty. Patients and methods 102 patients (39 men) with
Background: Health inequality and its social determinants are well-studied, but the determinants of inequality of alcohol consumption are less well-investigated. Methods: The total differential approach of decomposition of changes in the concentration index of the probability of participation in alcohol consumption was applied to 8-year longitudinal data for Swedish women aged 28-76 in 1988/89.

Popular Abstract in Swedish Sammanväxningar/ärrbildningar i buken och bröstkorgen efter kirurgiska ingrepp är mycket vanligt. Bland de patienter som opereras kommer cirka 95 % att få någon form av sammanväxningar. Nästan 1 procent av alla inläggningar på kirurgiska avdelningar och tre procent av alla bukoperationer anses i grunden vara orsakade av sammanväxningar i buken.

Open Educational Resources (OER) are teaching, learning and research materials available on the Internet. Resources are open and free, and usually under creative commons licenses (cc). Depending on the licenses resources are allowed to be used, reused, transmitted, and also sold openly and freely. Internationally, the OER movement is very strong. In Sweden, however, the trend towards open publicat
Although estrogen receptor-alpha (ERalpha) is a marker used to identify breast cancer patients most likely to benefit from endocrine therapy, approximately 50% of ERalpha-positive breast carcinomas are resistant to tamoxifen. Preclinical studies have shown that phosphorylation of ERalpha at serine-118 (ERalphaS118-P) is required for tamoxifen-mediated inhibition of ERalpha-induced gene expression.
