Due to acid rain and nitrogen deposition, there is growing concern that other mineral nutrients, primarily potassium and phosphorus, might limit forest production in boreal forests. Ectomycorrhizal (EcM) fungi are important for the acquisition of potassium and phosphorus by trees. In a field investigation, the effects of poor potassium and phosphorus status of forest trees on the production of EcM

We present a comparative study of solvent effects on the N-15 NMR shielding constants and the lowest electronic excitation energy (n -> pi*) in the three diazines (pyrazine, pyrimidine, and pyridazine) in aqueous solution. This solvent is modeled using either a polarizable continuum model (PCM) or a discrete polarizable model (DPM). We analyze the results obtained with the two models in terms of d

Here we report complement factor I deficiency in an 11-y-old girl from a consanguineous Turkish family, who presented with recurrent pyogenic infections, vasculitic eruptions and immune complex glomerulonephritis. A moderately low C3 level together with the clinical picture suggested a deficiency affecting regulation of complement activation. Analysis of haemolytic activity revealed absence of alt

Artikeln jämför Norge och Sverige när det gäller facklig anslutning bland arbetare och tjänstemän och analyserar skillnader mellan organisationsmönstrens framväxt. De båda ländernas fackliga organisering sätts också in i ett större internationellt perspektiv.

Popular Abstract in Swedish Den moderna tekniken att operera förslitna höftleder infördes av John Charnley i England på 1960-talet. Lårbenshuvudet ersattes med en metallkula på ett skaft och ledhålan på bäckenbenet med en skålformad plastkomponent. Bägge komponenterna sattes fast med en härdande plast, s.k. bencement. I början uppstod komplikationer med infektioner eller brott i själva protesen. DThis thesis focuses on the healing and remodeling of the morselized and impacted bone allograft, commonly used in revision of loosened hip prostheses with osteolysis. The influence on remodeling by the impaction procedure per se was analyzed, as well as the effects of endogenous bone graft proteins, and an exogenously applied growth factor (OP-1). A bone chamber model in rats was used, with the in

Objectives. To estimate the incidence of fatal colonic ischaemia (CI) and the cause-specific mortality of CI, and to describe the localization and extension of colonic infarction and quantify the risk factors associated with CI. Material and methods. Between 1970 and 1982 the autopsy rate in Malmo, Sweden, was 87%, creating the possibilities for a population-based study. Out of 23,446 clinical aut

OBJECTIVE: Approximately 5-10% of prostate cancer cases are caused by dominantly inherited susceptibility to the disease. Although advances have been made in research concerning the genetic mechanisms of hereditary prostate cancer, little is known about the psychological consequences. The aim of this study was to assess possible negative psychological effects of screening for prostate cancer in a

The overall purpose of this study is to describe and analyze the attitudes and behaviour of leisure time teachers. Attention will be paid to relevant features of the topic primarily addressed with regard to the interplay between teacher and child. The investigation has a qualitative inception where five leisure time teachers are observed with video recordings. Characteristics appear in the main ca

Purpose. Radiation enteritis is the main acute side-effect during pelvic irradiation. The aim of this study was to quantify the dose-volume relationship between irradiated bowel volumes and acute enteritis during combined chemoradiotherapy for rectal cancer. Material and methods. Twenty-eight patients with locally advanced rectal cancer received chemoradiotherapy. The radiation therapy was given w

The thermal unfolding of three SH3 domains of the Tec family of tyrosine kinases was studied by differential scanning calorimetry and CD spectroscopy, The unfolding transition of the three protein domains in the acidic pH region can be described as a reversible two-state process. For all three SH3 domains maximum stability was observed in the pH region 4.5 < pH < 7.0 where these domains unfold at

ST waveform analysis of fetal electrocardiogram (ECG) for intrapartum surveillance (STAN) is a newly introduced method for fetal surveillance. The purpose of this commentary is to assist in the proper use of fetal ECG in combination with cardiotocography (CTG) during labour. Guidelines and recommendations concerning CTG and ST waveform interpretation and classification are stated that were agreed

This paper focuses on usage modelling as a basis for both requirements engineering (RE) and testing, and investigates the possibility of integrating the two disciplines of use case modelling (UCM) and statistical usage testing (SUT). The paper investigates the conceptual framework for each discipline, and discusses how they can be integrated to form a seamless transition from requirements models t
