Here we present results from a field experiment in a sub-arctic wetland near Abisko, northern Sweden, where the permafrost is currently disintegrating with significant vegetation changes as a result. During one growing season we investigated the fluxes of CO2 and CH4 and how they were affected by ecosystem properties, i.e., composition of species that are currently expanding in the area (Carex rot
Coronary heart disease (CHD) is a common condition associated with a high mortality. There is now growing evidence that erectile dysfunction (ED) in men may be a suitable marker of sub-clinical cardiovascular disease, identifying patients at high risk for future CHD. We investigated the association between CHD risk factors and ED during a period of 25 years, in a population based cohort of men, a
Many concrete dams, and other concrete structures within the hydropower industry are old and in a more or less severe state of degradation. Leaching is, together with freeze-thaw, the most common degradation problem in Swedish hydraulic concrete structures. This report contains a literature survey of concrete leaching, and presents the results of an experimental determination of leaching.
alpha 1-Antitrypsin (AAT), a major endogenous inhibitor of serine proteases, plays an important role in minimizing proteolytic injury to host tissue at sites of infection and inflammation. There is now increasing evidence that AAT undergoes post-translational modifications to yield by-products With novel biological activity. One Such molecule, the C-terminal fragment of AAT, corresponding to resid
Objective: to describe the trends of self-reported past consumption of alcoholic beverages and ethanol intake from 1950. to 1995 within the European Prospective Investigation into Cancer and Nutrition (EPIC). Design: Data-on consumption of beer/cider, wine and liqueur/spirits were obtained age 20, 30 and 40 years to calculate average consumption and retrospectively at ethanol intake for the time p
Individual control and quantification of phosphate removal is desirable in dialysis treatment. Currently, no on-line method exists to quantify phosphate removal. We demonstrate that a multivariate calibration model based on infrared transmission spectra is capable of predicting phosphate, urea, and glucose concentrations at clinically relevant levels. The on-line monitoring of these components by
Parkinson's disease is a devastating neurological condition that affects at least four million people. A striking feature of this disorder is the preferential loss of dopamine-producing neurons in the midbrain. Several aetiological triggers have been linked to Parkinson's disease, including genetic mutations and environmental toxins, but the pathway that leads to cell death is unknown. Recent deve
The aim of this study is to examine the two novels Le Rouge et le Noir and La Chartreuse de Parme in the light of the theory of 'triangular desire', elaborated by René Girard in Mensonge romantique et vérité romanesque (1961). According to this theory, desire in Stendhal's novels – that is desire in a very general sense – is not spontaneous, but derived from a third part, that Girard labels the 'm
Rare species with small population sizes are vulnerable to perturbations such as disease, inbreeding, or random events. The threat arising from microbial pathogens could be large and other species could act as reservoirs for pathogens. We report finding three enteric bacterial species, Salmonella Amager, Campylobacter jejuni, and urease-positive thermophilic Campylobacter, in nestling free-flying
Shock waves are discontinuous solutions to quasi-linear partial differential equations and can be studied through a singular perturbation known as the vanishing viscosity technique. The vanishing viscosity method is a means of smoothing the shock, which we use to study the case of electromagnetic waves in bianisotropic materials. We derive the conditions arising from this smoothing procedure for a
A near-natural coastal dune system in NW Jutland, Denmark was investigated. The area contains a gradient in natural soil mobility with the highest values in dynamic white dunes dominated by Ammophila arenaria, and low mobility in fixed decalcified dune heath with Empetrum nigrum and Calluna vulgaris. A total of 267 plots was investigated and presence of mosses and rooted vascular plants recorded.
