På trots mot tillvarons tomhet : Emmanuel Levinas och 1900-talets meningskris
Artikeln behandlar 1900-talets meningskris såsom den återspeglas i Emmanuel Levinas och Hans Jonas tänkande.
Development and testing of a self administered version of the Freezing of Gait Questionnaire
Background: The Freezing of Gait Questionnaire (FOGQ) was developed in response to the difficulties of observing and quantifying freezing of gait (FOG) clinically as well as in laboratory settings. However, as the FOGQ is a clinician-administered patient-reported rating scale it cannot be used in postal surveys. Here we report the development and measurement properties of a self-administered versi
Lens optical properties in the eyes of large marine predatory teleosts.
The optical properties of the crystalline lenses were studied in a variety of large predatory teleosts (bony fishes) that forage in the open ocean, some of them at considerable depths. We found the first fish lenses that are free of measurable longitudinal spherical aberration, i.e., are perfectly monofocal, in contrast to the multifocal lenses that are typical for smaller fishes living close to t
Small-amplitude Stokes and solitary gravity water waves with an arbitrary distribution of vorticity
This paper presents an existence theory for small-amplitude Stokes and solitary-wave solutions to the classical water-wave problem in the absence of surface tension and with an arbitrary distribution of vorticity. The hydrodynamic problem is formulated as an infinite-dimensional Hamiltonian system in which the horizontal spatial coordinate is the time-like variable. A centre-manifold technique is

Measurement methods for stored VOC in concrete floors
Two methods used to determine stored VOC (volatile organic compounds) in concrete slabs has been compared. These methods are frequently used in investigating indoor environment problems where emissions from moisture damaged floorings are suspected. Comparative measurements were made in situ, and the results show good agreement with expected values, especially in measurements of a profile at severa
Expression pattern of anti-Müllerian hormone (amh) in the hybrid fish complex of Squalius alburnoides
In fish of the Squalius alburnoides complex, hybridisation and polyploidy have affected sex ratios, resulting in strong correlations between sex and genotype. The preponderance of females among triploids and the occurrence of an all male lineage among diploids seem to imply that sex ratio deviations should have a strong genetic basis. Until now, no information has been gathered regarding the molec
Intermolecular Pauson-Khand reactions on a galactose scaffold
An intermolecular Pauson-Khand reaction involving a carbohydrate scaffold having a pendant alkyne provides galactose derivatives with a cyclopentenone moiety in the C3-position in up to 85% yield.
The phase equilibria in the Au-In-Ga ternary system
The phase equilibria of the Au–In–Ga system were investigated for the first time using Differential Thermal Analysis (DTA), X-Ray Diffractometry (XRD), Energy Dispersive X-ray Spectroscopy (EDS) and Scanning Electron Microscopy (SEM). A new ternary phase (Au2InGa2) with the hexagonal structure (P63/mmc) was discovered which melts incongruently at 394 °C. From the experimental results, several inva
Racemic tricarbonyl[(4a,5,6,7,8,8a-eta)-2-phenyl-3,4-dihydro-2H-1-benzopyran]chr omium(0)
The title compound, [Cr(C15H14O)(CO)(3)], displays a distorted envelope configuration of the dihydropyrane ring. The dihedral angle between the phenyl and phenylene rings is 50.63 (4)degrees. The Cr-0 atom is coordinated by three CO groups and the phenylene ring of the flavan ligand in an eta(6) mode, with a common arene-to-metal distance
The R&D-growth paradox arises in fast-growing sectors
Several notions of a R&D paradox can be found in the literature. In the Swedish Paradox version, the emphasis is normally on high and growing levels of business R&D connected to comparatively low GDP growth rates. This paper examines whether this pattern is consistent over time and, more importantly, which sectors drive the aggregate patterns. Based on an investigation of the entire Swedis
"You child is just wonderful”: On ethics and access in research with children
This article discuss the consequences of the ambiguous view of children in the ethical guidelines – the ambitions to “give voice” while also “protect” – with a point of departure taken in the Swedish context, and in an actual research process of a project on children and care. It shows how the regulation of informed consent through the parent compromises the ideals of child-centred research; first

Early life origins of health and well-being in modern Sweden
Popular Abstract in English The aim of this thesis is to examine the role of early life environments for a variety of individual-level health and socioeconomic outcomes in contemporary Sweden. A research framework has recently emerged suggesting that individual long-term wellbeing is, to a large extent, dependent on the establishment of a healthy trajectory of growth and development during the earThe aim of this thesis is to examine the role of early life environments for a variety of individual-level health and socioeconomic outcomes in contemporary Sweden. Ever-expanding human lifespans have contributed to the emergence of novel socio-health phenomena confronting contemporary Swedish society. A new research framework has emerged in the last 30 years suggesting that individuals’ ability t
Analysis of the Auditory Perception of Ultrasound Doppler Signals to Improve Pregnancy Risk Assessment
In high-risk pregnancies, the transport of oxygen and nutrients from maternal to fetal blood via the placenta is often impaired. To assess the risk, pulsed Doppler ultrasound (US) is used to evaluate the flow velocity waveform in the umbilical artery with the pulsatility index (PI), which is derived from the velocity envelope of the Doppler power spectrum. However, simply listening to the Doppler
Denying Antecedents and Affirming Consequents: The State of the Art
Recent work on conditional reasoning argues that denying the antecedent [DA] and affirming the consequent [AC] are defeasible but cogent patterns of argument, either because they are effective, rational, albeit heuristic applications of Bayesian probability, or because they are licensed by the principle of total evidence. Against this, we show that on any prevailing interpretation of indicative co

The role of a simulator-based course in coronary angiography on performance in real life cath lab
Background: The aim of this study was to explore if a course consisting of lectures combined with simulator training in coronary angiography (CA) could accelerate the early learning curve when performing CA on patients. Knowledge in performing CA is included in the curriculum for the general cardiologist. The method, according to American College of Cardiology and European Society of Cardiology gu
Anorectal malformations - their impact on early phases in life
Popular Abstract in Swedish Populärvetenskaplig sammanfattning Född utan ändtarmsöppning – det finns mer hjälp! Varje år föds femtio barn i Sverige utan ändtarmsöppning, så kallad analatresi. De sista 2-3 centimetrarna av ändtarmen saknas liksom ändtarmsöppningen och delar av ringmuskeln. Orsaken tros vara plötsligt uppkomna genförändringar tidigt hos fostret. Starten i livet blir svår eftersom deAbstract: Background : Anorecta l malformation s (ARM) occur in 4: 10000 newborn children with the gender distribut ion 1:1.5 females:males. The reconstruction of ARM, posterior sagiccal anorectal plasty (PSARP), was implemenred worldwide in the late 1980s and therefore the follow-ups are limited. Aims: To assess bowel symptoms in children and adolescents with ARM, operated on with PSARP, and to
