The crystal structures of Bi2.5Na0.5Ta2O9 and Bi2.5Nam-1.5NbmO3m+3 (m = 3,4) have been investigated.ysis of their neutron powder diffraction by the Rietveld anal patterns (lambda = 1.470 Angstrom). These compounds belong to the Aurivillius phase family and are built up by (Bi2O2)(2+) fluorite layers and (A(m-1)BnO(3m+1))(2-) (m = 2-4) pseudo-perovskite slabs. Bi2.5Na0.5Ta2O9 (m = 2) and Bi2.5Na2.5

A natural treatment system for the treatment of leachate was Studied at Moskogen landfill in southern Sweden. This facility consists of three consecutive ponds and a soil-plant (SP)system. A test area, receiving water from the third pond with the same hydraulic load as the SP-systern, was Used for estimation of the latter system. Quality parameters including biochemical oxygen demand, total organi

This paper summarises the major recommendations and conclusions of the third Forum of the European Network on Energy Research (ENER) which took place in June 2002 in Budapest. The major perceptions of this meeting as well as the most important conclusions and recommendations for energy policy makers are compiled in this summary. The statements compiled in the following represent a consensus within

Formation of incipient charnockite in Söndrum, SW Sweden and the Kerala Khondalite Belt (KKB), S. India is accompanied by zircon growth. The age of the dehydration event is constrained by dating newly formed zircon to 1397±4 Ma (2?, MSWD=1.7) in Söndrum and ca. 520-510 Ma in S. India by secondary ionization mass spectrometry (SIMS). The formation of incipient charnockites correlates with regional

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
