The influence of electron doping, via deposition of small amounts of Cs, on the electronic structure of has been studied by high-resolution photoelectron spectroscopy (PES) and x-ray absorption spectroscopy (XAS), utilizing synchrotron radiation. The changes in the electronic structure were monitored by PES of the valence band and of the O 1s, Bi 4f, Bi 5d, Ca 2p and Sr 3d core levels, and by XAS

We present in this work in vitro measurements of the force ejecting DNA from two distinct bacteriophages (T5 and lambda using the osmotic-suppression technique. Our data are analyzed by revisiting the current theories of DNA packaging in spherical capsids. In particular we show that a simplified analytical model based on bending considerations only is able to account quantitatively for the experim

The restoration of cognitive function was studied in 10 healthy men aged 26 years (25.5 +/- 1.2 years; mean +/- SD) after insulin-induced hypoglycaemia (arterialized blood glucose 2.5 +/- 0.4 mmol l-1) for 62 +/- 8 min. Another group of six men participated in a single blind sham study for comparison. The hypoglycaemic event caused a significant increase (p = 0.006) in serum adrenaline levels. Rat

PURPOSE: To analyze patients after endovascular repair of abdominal aortic aneurysm (AAA) with respect to distal migration of stent-grafts and its underlying causes. MATERIALS AND METHODS: Sixty-five patients underwent endovascular repair between January 1994 and February 1997. There were seven women and 58 men, with a mean age of 71 years (range, 51-84 years). Three patients died in the periopera

Deep-inelastic scattering data in the range 150 < Q(2) < 35000 GeV2 are used to investigate the minimum jet separation necessary to allow accurate description of the rate of dijet production using next-to-leading order perturbative QCD calculations. The required jet separation is found to be small, allowing about 1/3 of DIS data to be classified as dijet, as opposed to approximately 1/10 with more

Exposure to organic dust originating from biofuels can cause adverse health effects. In the present study we have assessed the dustiness in terms of microbial components and particles of various biofuels by using a rotating drum as a dust generator. Microbial components from straw, wood chips, wood pellets and wood briquettes were quantified by several methods. Excellent correllations (r greater t

Several lines of evidence indicate a causal role of the cytokine interleukin (IL)-6 in the development of type 2 diabetes in humans. Two common polymorphisms in the promoter of the IL-6 encoding gene IL6, -174G > C (rs1800795) and -573G > C (rs1800796), have been investigated for association with type 2 diabetes in numerous studies but with results that have been largely equivocal. To clarify the

This article describes and analyzes the Euro cash changeover process. The European Monetary Union, EMU, is a unique event in history, although other monetary unions were formed and existed long before. Still, this giant experiment makes it possible to study changes in the monetary environment from a unique and new position. The article tries to find factors that can help to explain the different p

Objective: To assess mortality in patients with rheumatoid arthritis ( RA) treated with tumour necrosis factor (TNF) inhibitors, compared with a standard RA population. Methods: Patients were recruited from a regional register, which includes over 90% of patients with RA treated with TNF blockers in the area in 1999 or later, and a local community-based cohort of patients with RA, established in 1

Abstract in Undetermined BACKGROUND: The absence of all Kell blood group antigens (K0 phenotype) is very rare. K0 persons, however, can produce clinically significant anti-Ku (K5) after transfusion and/or pregnancy and require K0 blood for transfusion. Ten alleles giving rise to the K0 phenotype have been reported: different populations were studied although none from Scandinavia. STUDY DESIGN AND

Popular Abstract in Swedish Hur förändras organisationer? Medan statsvetenskaplig ny-institutionell teori är mer inriktad på att förklara varför institutioner är seglivade och svåra att förändra, så antar ekonomisk organisationsteori att organisationer relativt enkelt anpassar sig till omgivningens krav. Det sociala nätverks-perspektivet fokuserar de strukturer av samarbete och tillit som utvecklaNew institutionalist approaches are inherently weak at accounting for institutional change. In this book, social network analysis is proposed as a key to institutional change. The social network perspective focuses emergent patterns of interpersonal interaction and the resulting ties of interpersonal trust. As a complement and contrast to both March and Olsen’s influential new institutionalist "lo

A comparison, based on a study of how time is treated, between three development tools for real time expert system is exposed. After a presentation of the tools, some of their advantages and disadvantages arepinpointed. Since these tools are only a partial answer to the problem of real time within the expert system's area, a standpoint concerning a good use of each tool is given.

This thesis consists of a collection of essays on coordination in games and competition in international oligopolies. The first essay presents a theoretical analysis of a simple coordination game in which players simultaneously choose efforts from a compact interval. The original game has a continuum of Pareto-ranked equilibria. In a noisy variant of the model an error term is added to each player
