In this article further progress is made in extending the Burchnall-Chaundy type determinant construction of annihilating polynomial for commuting elements to broader classes of rings and algebras by deducing an explicit general formula for the coefficients of the annihilating polynomial obtained by the Burchnall-Chaundy type determinant construction in Ore extension rings. It is also demonstrated
Dekkera bruxellensis and Saccharomyces cerevisiae are considered two phylogenetically distant relatives, but they share several industrial relevant traits such as the ability to produce ethanol under aerobic conditions (Crabtree effect), high tolerance towards ethanol and acids, and ability to grow without oxygen. Beside a huge adaptability, D. bruxellensis exhibits a broader spectrum in utilizati
The thorough experimental characterization of a dowel-type connection under various combinations of bending moments and normal forces is presented in this study. Double-shear steel-to-timber connections with 12 and 20 mm steel dowels were tested in a 4-point bending test set-up. The load, between the connected steel and wood beams, was transferred by the dowels themselves and also via an additiona
Orthostatic hypotension (OH) is a relatively common heterogenous and multifactorial disorder, traditionally classified as neurogenic (less common but often more severe), or non-neurogenic (more common, with no direct signs of autonomic nervous system disease). The different clinical variants of orthostatic intolerance include initial, classical and delayed OH as well as postural tachycardia syndro
The Gauss-Lagrange stochastic wave model is known to produce irregular waves with realistic degrees of asymmetry. We present the basic structure of the model and illustrate three of its characteristic properties: front-back asymmetry, particle orbits, and average horseshoe pattern. We also study the effect of a linear filter in a wave energy converting (WEC) system on asymmetry and on average powe
Intervention studies have shown that high-intensity training programs with duration of 1-3 years can influence bone mass in post-menopausal women. We wanted to investigate whether moderate physical activity could be associated with reduced post-menopausal bone loss also in the long-term perspective. We evaluated changes in bone mass and bone structure by repeated single-photon absorptiometry measu
Objectives. Previous research has demonstrated mortality differences between immigrants and natives living in Sweden. The aim of this study is to investigate the effects of early life conditions in the country of birth and current socio-economic conditions in adult life in Sweden on cardiovascular, cancer, all other cause and total mortality among immigrants and natives in Sweden. Design. The coho
The Ukrainian Shield comprises the exposed crust of the large Palaeoproterozoic protocraton Volgo-Sarmatia, which together with the Fennoscandian crustal segment constitutes the East European Craton ("Baltica"). Geological and geophysical data indicate that 1.80 to 1.75 Ga mafic dykes related to anorthosite-mangerite-charnockite-granite (AMCG) plutons are widespread within the Ukrainian Shield. We
The paper is a sounding of Ulrich Beck's and Edgar Grande's conceptual map of the varieties of second modernity - Western and Non-Western, European and beyond - that makes up today's world. Their mapping is examined in the light of two, striking analytical perspectives associated with Ulrich Beck: everyday 'cosmopolitization' and his call for a methodological cosmopolitanism. A line of inquiry exp
The aim of this study was to examine the effects of speech rate on children's performance on a widely used language comprehension test, the Test for Reception of Grammar, version 2 (TROG'2), and to explore how test performance interacts with task difficulty and with the child's working memory capacity. Participants were 102 typically-developing Swedish-speaking children randomly assigned to one of
We use time-dependent density functional theory together with a set of extensive multidimensional visualization techniques to characterize band gap, optical absorption properties, intramolecular and intern-wreaths charge transfer, exciton binding energy, charge transfer integral, and the rate of charge transfer and recombination in the PC60BM:PDDTT Model of an organic,solar cell. These theoretical
OBJECTIVE.: To introduce a novel, simple, utility based outcome measure, the Number Needed per Quality adjusted life year (QALY) gained (NNQ), and to apply it in clinical practice in anti-TNF treated patients with rheumatoid arthritis (RA), psoriatic arthritis (PsA), and spondylarthritis (SpA). METHODS.: The NNQ is the number of patients one has to treat in order to gain 1 QALY. It is calculated a
In this 24-month follow-up of a phase II study in patients with castration-resistant prostate cancer (CRPC) and bone metastases, radium-223 (4 injections of 50 kBq/kg every 4 weeks [n = 33]) improved median overall survival vs. matching placebo (n = 31) (65.3 vs. 46.4 weeks, respectively; log-rank P = .056), with no long-term safety concerns. Data suggest that treatment of bone disease with radium
The MAX IV 3 GeV storage ring, currently under construction, pursues the goal of low electron beam emittance by using a multi-bend achromat magnet lattice, which is realised by having several consecutive magnet elements precision-machined out of a common solid iron block, 2.3-3.4 m long. With this magnet design solution, instead of having 1320 individual magnets, the MAX IV 3 GeV storage ring is b
Abstract Objective. The aim of this study was to analyse the rate of use of bacillus Calmette-Guérin (BCG) at a population-based level, and the overall mortality and bladder cancer mortality due to stage T1 bladder cancer in a national, population-based register. Materials and methods. In total, 3758 patients with primary stage T1 bladder cancer, registered in the Swedish Bladder Cancer Register b
Sexual selection is often viewed as a promoter of population divergence, although some forms of sexual selection could rather hamper divergence. In the present study, we investigated whether sexual selection promotes divergence in sexually-selected traits. We studied population variation in sexual selection in relation to colour morph and body size in islet and mainland populations of the Skyros w
