The exclusive and semi-exclusive branching ratios of the tau lepton hadronic decay modes (h(-)upsilon(tau), h(-)pi(0)upsilon(tau), h(-)pi(0)pi(0)upsilon(tau), h(-) >= 2 pi(0)nu(tau), 2h(-)h(+)upsilon(tau), 2h(-)h(+)>= 2 pi(0)upsilon(tau), 3h(-)2h(+)upsilon(tau) and 3h(-)2h(+) >= 1 pi(0)upsilon(tau)) were measured with data from the DELPHI detector at LEP.

The authors compared the influence of environmental enrichment on intact and lesioned brain, and tested the hypothesis that postischemic exposure to an enriched environment can alter dendritic spine density in pyramidal neurons contralateral to a cortical infarct. The middle cerebral artery was occluded distal to the striatal branches in spontaneously hypertensive rats postoperatively housed eithe

We measured the intracapsular pressure preoperatively in 18 hips (17 patients) before revision of a total hip arthroplasty because of aseptic loosening. Distension of the joint capsule was measured with sonography in 13 cases. In extension, the mean intracapsular pressure was 26 (0-60) mmHg, in extension and inward rotation it was 159 (24-280) mmHg, in extension and outward rotation it was 30 (3-6

OBJECTIVE: to study the proximal fixation of different aortic stent grafts in comparison to a hand-sewn anastomosis. DESIGN: experimental study. MATERIAL: the infrarenal aorta of 16 human cadavers were exposed, left in situ and transected 3 cm above the aortic bifurcation to mimic an infrarenal aortic neck. Stent grafts were deployed through a sheath 5 cm into the aorta. Ancure, Talent, Vanguard,

The growth rates and motility of dinoflagellates were studied in the field in the presence or absence of UVB radiation, as well as in the laboratory under artificial radiation conditions. Photosynthetically active radiation (PAR, 400–700 nm) and UVB radiation showed large variations due to cloud cover and seasonal changes in natural daylight. In Swedish coastal water, UVB radiation was attenuated

Objective: To describe anthropometric characteristics of participants of the European Prospective Investigation into Cancer and Nutrition (EPIC). Design: A cross-sectional analysis of baseline data of a European prospective cohort study. Subjects: This analysis includes study populations from 25 centres in nine European countries. The British populations comprised both a population-based and a 'he

Popular Abstract in Swedish Avhandlingen diskuterar tidigmedeltida skandinavisk konst, främst kyrkdörrar och portaler från Sverige och Norge. Kyrkans ingång är särskilt lämplig att studera dels eftersom den markerade en gräns för det heliga rummet, dels därför att den var en viktig mötesplats i lokalsamhällena. Genom kontextualiseringar och kritisk forskningshistorik skapas en delvis ny bild av deThe thesis discusses Medieval Scandinavian art, in particular church doors and portals from 12th and 13th century Sweden and Norway. The entrance of the church was a demarcation of holiness, but also a meeting place for the local communities, where otherwise secular activities could be legitimatized by the ecclesiastical context. This makes the doors and portals of special interest for the study o

This study examines the attempts made by one local government in China, Shenzhen, to improve its investment environment for foreign-invested enterprises through administrative reforms between 1980 and 1997. Three empirical questions are posed: what reforms have been undertaken, what effects have they had and how have changes in the organizational environment affected them. The theoretical aim is

Dercums sjukdom, adiposis dolorosa eller, mera allmänt, fettvävsreumatism är en relativt okänd sjukdom trots att den beskrevs redan 1888 av den amerikanske neurologen Francis Xavier Dercum. Den drabbar företrädesvis 20–40-åriga kvinnor, men kan även debutera hos barn. Kännetecknande är en uttalad smärta i fettväven. Patienterna har liksom fibromyalgikerna ofta nonchalant avfärdats med att »alla fe

The thesis contains a general theoretical and historical argument and the application of this argument to specific empirical data gathered over a period of 23 years among young people in Iceland. The first part consists of a selective review of the international research literature on television at the time of writing. This review leads to the establishment of three stages in the development of t

The insulin-degrading enzyme is responsible for the intracellular proteolysis of insulin. Its gene IDE is located on chromosome 10, in an area with suggestive linkage to type 2 diabetes and related phenotypes. Due to the impact of genetic variants of this gene in rodents and the function of its protein product, it has been proposed as a candidate gene for type 2 diabetes. Various groups have explo

In a replicated field experiment we studied the effects of natural densities of two exotic consumers, the predatory and herbivorous signal crayfish (Pacifastacus leniusculus) and the predatory rainbow trout (Oncorhynchus mykiss), on multiple trophic levels of a pond community. The goals were to: (1) determine the individual and combined effects of predators on macroinvertebrates, macrophytes, and

The combination of Doppler tissue imaging and myocardial contrast echocardiography has the potential to provide information about motion and perfusion of the myocardium in a single examination. The purpose of this study was to establish how the presence of ultrasound contrast agent (UCA) affects measurements of Doppler tissue velocities in vivo and in vitro. We performed echocardiography in 12 pat

The charmed strange baryon Xi(c)(0) was searched for in the decay channel Xi(c)(0) -> Xi(-)pi(+), and the beauty strange baryon Xi(b) in the inclusive channel Xi(b) -> Xi(-)l(-)(nu) over barX, using the 3.5 million hadronic Z events collected by the DELPHI experiment in the years 1992-1995. The Xi(-) was reconstructed through the decay AT, using a constrained fit method for cascade decays. An iter

Ribonucleotide reductases (RNRs) catalyze the reduction of ribonucleotides into deoxyribonucleotides, which constitute the precursor pools used for DNA synthesis and repair. Imbalances in these pools increase mutational rates and are detrimental to the cell. Balanced precursor pools are maintained primarily through the regulation of the RNR substrate specificity. Here, the molecular mechanism of t

In dual cultures Oudemansiella mucida and Xerula melanotricha (basidiomycetes) react to the presence of living Penicillium notatum or P. turbatum with an increased production of strobilurin A (1) or X (2). P. notatum in turn reacts to the two basidiomycetes or their antibiotic strobilurin A alone with the production of N-(2-hydroxypropanoyl)-2-aminobenzoic acid amide (3) or chrysogine (4). P. meli
