The European heavy metals in mosses biomonitoring network provides data on the concentration of 10 heavy metals in naturally growing mosses and is currently coordinated by the UNECE ICP Vegetation (United Nations Economic Commission for Europe International Co-operative Programme on Effects of Air Pollution on Natural Vegetation and Crops). The technique of moss analysis provides a surrogate, time

The dut gene, which encodes Eseherichia coli deoxyuridine 5'-triphosphate nucleotidohydrolase (dUTPase), has been recloned to increase overexpression of the enzyme and to enable simplification of the purification protocol into a one-step procedure. The gene was cloned into the vector pET-3a and expressed in E. coli BL21(DE3) pLysS under the control of a bacteriophage T7 promotor. Induction results

Net ecosystem productivity (NEP) was studied in a bog located in the middle taiga of Siberia using two approaches, the accumulation of peat above the hypocotyl of pine trees, and the eddy covariance flux methodology. NEP was 0.84 tC ha-1 yr-1 using the peat accumulation method; it was 0.43–0.62 tC ha-1 yr-1 using eddy covariance over three growing seasons. These data were compared with NEP of the

Popular Abstract in Swedish Syftet med avhandlingen var att utarbeta en vård- och omvårdnadsmodell som förbättrar livskvalitet och hälsa hos svenska kvinnor med Irritable Bowel Syndrome (IBS). Avhandlingen består av 4 delstudier: Delstudie 1. Kvinnor med IBS upplevelse av en god livskvalitet. Delstudie 2. Utbildning av kvinnor med IBS. Delstudie 3. Hälsoaspekter i relation till användandet av Irritable Bowel Syndrome (IBS) is a common, worldwide, functional disorder affecting a significant number of people, predominantly women. Etiology and pathophysiology is insufficiently understood, but the research over the past decade has led to progress in the understanding of IBS, and it is generally accepted that the symptoms of IBS are multidetermined. However, management of IBS is still a cha

An experiment of laser-triggered electric discharges has been conducted in a uniform background electric field. By focusing the beam of a pulsed Nd-YAG laser (wavelength 532 nm, pulse duration 5 ns) in a narrow (15 mm) plane-parallel air gap exposed to a dc voltage, streamer discharges and disruptive discharges were triggered.. The laser energy and the background electric field strength were varie

As ascites is related to liver cirrhosis in 80% of the patients, the present therapeutic guidelines are focused on ascites in liver cirrhosis. A combination of spironolactone and furosemide is recommended as first line therapy in patients with mild to moderate ascites and is effective in 90% of patients. In patients with pronounced or tense ascites, first line treatment is total paracentesis with

Abstract in French De la métaphore à l’allégorie dans la sémiotique écologique Göran Sonesson Si l’allégorie est une métaphore filée, comme disent les classiques, il faut commencer par étudier cette dernière. Le système de Groupe µ, dont nous avons donné ailleurs une version revue et corrigée, esquive cette terminologie traditionnelle, mais si l’on veut appliquer un tel système à la rhétorique lFrom metaphor to allegory in ecological semiotics Göran Sonesson If allegory is an extended metaphor, as classical rhetoric would have it, we should have to start by studying the latter. The system of the µ group, which I have elsewhere tried to amend and build out, steers clear of this traditional terminology, but if the resulting system should still be relevant to linguistic rhetoric, correlat

BACKGROUND:Considering the fact that donor age is a major risk factor for graft survival, and taking into account the importance attached to the principle of autonomy in the Swedish Health Care Law, we decided that allocation of kidneys from marginal donors should be restricted to patients who have given their informed consent. Written information was given to the patients on the waiting list for

Popular Abstract in Swedish Avhandlingen innehåller ett inledningskapitel följt av fyra separata studier. Studierna behandlar olika aspekter av humankapital, begåvning och immigration. I den första studien, Ability and Rates of Return to Schooling ? making use of the Swedish Enlistment Battery Test, används det svenska mönstringstestet för att skatta avkastningen på utbildningen för individer medThis thesis consists of an introductory chapter followed by four separate papers. The papers deal with various aspects of human capital, ability and migration. Using the Swedish Military Enlistment test, the first paper, Ability and Rates of Return to Schooling ? making use of the Swedish Enlistment Battery Test, estimates the return to schooling for individuals belonging to different parts of th

We describe JastAdd, a Java-based system for compiler construction. JastAdd is centered around an object-oriented representation of the abstract syntax tree where reference variables can be used to link together different parts of the tree. JastAdd supports the combination of declarative techniques (using Reference Attributed Grammars) and imperative techniques (using ordinary Java code) in implem

Two methods for visual evaluation of image quality of clinical radiographs have been compared. In visual grading analysis (VGA) specified anatomical structures in an image are visually compared with the same structures in a reference image, and in a free-response forced error (FFE) experiment - an extension of conventional ROC (receiver operating characteristics) analysis - the objective is to cor

During spring and autumn 2001, we screened 13,260 migrating birds at Ottenby Bird Observatory, Sweden, and found 3.4% were infested with ticks. Four birds, each a different passerine species, carried tickborne encephalitis virus(TBEV)-infected ticks (Ixodes ricinus). Migrating birds may play a role in the geographic dispersal of TBEV-infected ticks.
