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.

This e-book contains contributions from two sessions at the archaeological conference Nordic TAG VIII that took place in Lund in 2005. It is also the first volume of a digital publication, Archaeology @ Lund, published by the Department of Archaeology and Ancient History at Lund University. The two sessions that are published together here are The Practical Aspects of the History of Archaeology an

Popular Abstract in Swedish The last period of life among older people has been very little explored, even though it is well known that for the majority of the population death will occur in old age, both in Sweden and in other western countries. The intention in Swedish society is to provide high quality end of-life care for everyone (SOU 2001:6), not just to those receiving care in a hospital orThe aim of this thesis was to investigate old people's care and quality of life during the last period of life, but also to investigate their own and next-of-kin's experience of this phase. The thesis is based on four studies using separate samples. The sample (n=1198) in study I was drawn from the care and services part of the sub-study ?Good Aging in Skåne? (GAS). The criteria for inclusion in s

Popular Abstract in Swedish Stommen i "det sydkoreanska miraklet" utgjordes av chaebolkonglomeraten, som inom ramen för "developmental state" blev instrumentet för ekonomisk tillväxt. Med ett minimum av eget kapital men med privat ägarkontroll och genom lånefinansiering expanderade dessa företag. Hur kunde denna "omöjliga" konfiguration överleva? Avhandlingen analyserar hur detta kunde fortgå ändaThe chaebol conglomerates, which constituted the backbone of the "South Korean miracle", became the instrument for economic growth within a framework laid down by the "developmental state". With a minimum of own capital, but with private owner-control and loan-financing, these chaebols were able to expand. How could this "impossible" configuration survive? The thesis analyses how this could contin

Wind noise was measured in four behind-the-ear hearing instruments with different microphone openings. A silent airflow of 7 m/s was directed toward the ear of a Kemar head and the resulting wind noise was measured. The amplification was set to an insertion gain of 35 dB at 1.6 kHz. The wind noise amplitude at the position of the drum ranged from 84 to 97 dB(A). The hearing instrument with a parti

In semen. the gel proteins SgI and SgII (semenogelins I and II) are digested by PSA (prostate-specific antigen), resulting in liquefaction and release of motile spermatozoa. Semen contains a high concentration of Zn2+, which is known to inhibit the protease activity of PSA. We characterized the binding of Zn2+ to SgI and SgII and found evidence that these proteins are involved in regulating the ac
