The aims of the paper are to; i)evaluate the rate and direction of present changes in lead (Pb) and cadmium (Cd) soil pools of Swedish forests; ii) discuss processes of importance for leaching of Pb and Cd in Swedish forest soils. The presently ongoing changes of Pb and Cd pools of Swedish forest soils are evaluated by compilation of data from the literature and unpublished sources. It is conclude
Abstract in French L’effet de la courbure interfaciale sur le point de congélation de liquides retenus dans des capillaires permet, en principe, de déterminer une distribution du diamètre des pores, d’après la courbe point de congélation/volume congelé. On procède à un examen des bases théoriques et l’on montre qu’il existe une similitude formelle avec les méthodes par condensation capillaire qui By utilising the effect of interfacial curvature on the freezing-point of liquids confined in capillaries, it is in principle possible to determine a pore-size distribution, from the curve of freezing-point against volume frozen. The method is formally similar to capillary condensation methods based on the Kelvin equation. Suitable experimental techniques are described. A comparison with the resul
A section, almost 20 km long and up to 80 m high, through alternating layers of diamict and sorted sediments is superbly exposed on the north coast of the Kanin Peninsula, northwestern Russia. The diamicts represent multiple glacial advances by the Barents Sea and the Kara Sea ice sheets during the Weichselian. The diamicts and stratigraphically older lacustrine, fluvial and shallow marine sedimen
The relationship between use of corticosteroids and fracture risk was estimated in a meta-analysis of data from seven cohort studies of similar to42,000 men and women. Current and past use of corticosteroids was an important predictor of fracture risk that was independent of prior fracture and BMD.
Monogalactosyldiacylglycerols (MGDG), digalactosyldiacylglycerols (DGDG) and sulfoquinovosyldiacylglycerols (SQDG) are major lipids in vegetable food. Their digestion and absorption are unknown. This study examines the hydrolysis of galactolipids in vitro with human duodenal contents, pancreatic juice, and purified human pancreatic lipases. Galactolipids were incubated with human duodenal contents
Treatment of severe bleeding and the performance of surgery in haemophilia patients with inhibitors creates severe problems. It is generally agreed that treatment is most effective if circulating levels of factor VIII/IX can be achieved long enough for control of haemostasis. Immunoadsorption with protein A for the removal of inhibitor has improved treatment for patients with initial inhibitor tit
Seven patients with rheumatoid arthritis and posterior atlanto-axial dislocation are presented. The patients were elderly women who had suffered with the disease a long time. In all cases earlier cervical radiographs were available, excluding any predisposing congenital anomaly. Fracture and arthritic destruction of the dens, of parts of the body of the axis, or of the anterior arch of the atlas p
Molecular variation is often used to infer the demographic history of species, but sometimes the complexity of species history can make such inference difficult. The willow warbler, Phylloscopus trochilus, shows substantially less geographical variation than the chiffchaff, Phylloscopus collybita, both in morphology and in mitochondrial DNA (mtDNA) divergence. We therefore predicted that the willo
In the wake of the geo-political development in recent years, the question of sacrifice has come to the fore in the contemporary philosophical discussion. Does sacrifice merely sharpen conflicts between cultures, or should it be seen as an inevitable part of their foundation? This article addresses the question from the perspective of the biblical view of sacrifice, expressed paradigmat- ically in
The eyes of visually prominent animals such as vertebrates, cephalopods, and arthropods generally subserve a multitude of visual tasks. Naturally, early stages in the evolution of these complex visual organs must have been simpler, and subserved a smaller number of visual tasks. Hence, eye evolution is driven by a consecutive accumulation of visual tasks. Each task adds to the requirements on eye
Background. Describing the illness-story from a patient perspective could increase understanding of living with a chronic disease for health professionals and others, facilitate decision-making about treatment and enhance information about the outcome from a patient perspective. Aim. To illuminate patients' illness experiences of having a gastro-oesophageal reflux disease (GORD), going through sur
We analysed the relative importance of individual versus institutional factors in explaining variations in the utilisation of physician services among the 50+ in ten European countries. The importance of the latter was investigated, distinguishing between organisational (explicit) and cultural (implicit) institutional factors, by analysing the influence of supply side factors, such as physician de
Understanding individual and population responses to climate change is emerging as an important challenge. Because many phenotypic traits are sensitive to environmental conditions, directional climate change could significantly alter trait distribution within populations and may generate an evolutionary response. In species with environment-dependent sex determination, climate change may lead to
The Strategic Systemic Thinking (SST) framework is presented as a stepping stone towards enabling the refocusing of organizational analysis in Information Systems (IS). The paper introduces some of the fundamental assumptions regarding the objectives of the SST framework; such as sense making as learning processes build upon communicative actions. The main concepts of the SST framework are present
T cells obtained in a mouse model for rheumatoid arthritis are activated by a glycopeptide fragment from rat type II collagen (CII) bound to the class II major histocompatibility complex A(q) molecule. We report a comparative model of A(q) in complex with the glycopeptide CII260-267. This model was used in a structure-based design approach where the amide bond between Ala(261) and Gly(262) in the
