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

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

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 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

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

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

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

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

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

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

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

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.

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

This paper presents a pilot study in which specific activities of (14)C in hair and urine from 11 radiation workers handling (14)C-containing substances have been measured using accelerator mass spectrometry. Varying degrees of contamination were revealed: up to 63% excess in hair and 400% excess in urine. Although the (14)C excess reported in this study would result in low effective doses, it wou

The aim of this dissertation is to examine how differences in socioeconomic status, race and place of residence interact with infant and child mortality in Colombia over the period 1967-2010. One of the reasons why the study focuses on infant and child mortality is that the living conditions of children are outside their control, and therefore a good measure of inequality of opportunity. This stud

Single complex fluorescence polarization spectroscopy is applied to study the peripheral light harvesting antenna (LH2) from photosynthetic purple bacterium Rhodopseudomonas (Rps.) acidophila. The measured two-dimensional excitation-emission polarization plots are used to construct geometric representation for the absorbing B800 and emitting B850 as ellipses. The shape and orientation of the ellip
