Dynamics of spontaneous decay and corresponding emission spectrum areexactly treated for a system of two identical two-level atoms in 1D.Just a one-dimensional case is considered in order to maximally extractan information on mutual influence of spatially remote atoms through theradiation field. As a result, an effect is revealed and considered indetail that there exist stable (metastable) entangl

Free gases in scattering media and different techniques for such studies are discussed in the present paper. Connections between two techniques that constitute a major research area at our laboratory are presented. One of the techniques concerns measurements of free gas in scattering media, such as human tissue and food products, on a small scale, while the other one is a technique for trace-gas m

Katekeser är en genre som vanligtvis förknippas med lutheransk religionsundervisning, och inte revolutioner. Dess form, att ställa en antal givna frågor och ge ett definitivt svar för varje fråga synes lämna föga utrymme för självständigt och kritiskt tänkande. Frågandet som teknik är en retorik; syftet är att styra läsarens tänkande i avsedd riktning. Inpräntande av normer, inte radikala reflekti

Popular Abstract in Swedish Denna studie behandlar hur Ukraina har inkorporerat och brukat förintelsen och den ukrainska hungersnöden 1932-1933, den så kallade terrorhungersnöden, i den nya nationella historien och historiekulturen. Undersökningen tar sin utgångspunkt i det ökade intresset för förintelsen under senare år. Olika institutioner och aktörer har framfört utrotningen av Europas judar unThis study deals with the problem of how Ukraine has incorporated and made use of the Holocaust and the 1932?1933 famine (Holodomor) in its new national history and historical culture. The investigation departs from the increased interest in and attention devoted to the Holocaust in recent years. Various institutions and actors have brought the mass murder of Europe's Jews forward as an important

Two approaches to moral education are discussed in the article: one aiming at detachment in terms of personal autonomy, one aiming at relatedness in terms of a conscious socialisation into a shared morality of a community. The philosophical features of the two approaches are related to their respective pedagogical implications in a study of the pedagogical guidelines for confirmation work in the c

The trend of the service architectures developed in telecommunications today is that they should be open in the sense thatthey can communicate over the borders of different networks. Instead of each network having their own service architecture with their own applications, all networks should be able to use the same applications. 3GPP, the organization developing specifications for the 3G networks

The formation of titanium aluminides in Ti–Al elemental powder mixtures containing 25, 50 and 75 at.% Al, has been studied using differential scanning calorimetry (DSC). Phase evolution in the mixture was followed by heating the compacted samples up to 1273 K at 7.5 and 15 K min−1. The cooled samples were characterized using X-ray diffraction, scanning electron microscopy and energy-dispersive spe

Hypoxia, or low oxygen tension, is a major regulator of tumor development and aggressiveness. However, how cancer cells adapt to hypoxia and communicate with their surrounding microenvironment during tumor development remain important questions. Here, we show that secreted vesicles with exosome characteristics mediate hypoxia-dependent intercellular signaling of the highly malignant brain tumor gl

Methylchloroisothiazolinone (MCI)/methylisothiazolinone (MI) in aqua is present in the European baseline patch test series at 100 ppm, whereas 200 ppm has been used in Sweden since 1986, in Spain in the late 1980s, and, in recent years, also in the United Kingdom and Ireland.

We analyze the contribution of universities to innovative performance in China’s manufacturing sector. Our empirical analysis is based on a matched dataset comprising about 20 000 large and medium sized companies aggregated at the three-digit industry level and information on university knowledge output for 31 provinces between 1998 and 2004. We show that universities’ impact on commercial innovat

The home environment is a primary context for daily activities, especially among older adults and persons with disabilities. Functional and age-related decline can generate problems in relation to certain environmental features, necessitating modifications or other provisions of support. The determination of appropriate home interventions is best served using a person–environment (P–E) fit approac

Fibroblast growth factor 23 (FGF23) is a hormone with regulatory effects on mineral metabolism and arterial calcification. We aimed to study the association between FGF23 and risk of incident subarachnoid hemorrhage (SAH) in a nested case-control study.

A review on icing physics, ice detection, anti-icing and de-icing techniques for wind turbines in cold climate has been performed. Typical physical properties of atmospheric icing and the corresponding meteorological parameters are presented. For computational modeling of ice accretion on turbine blades, the LEWINT code was adopted to simulate ice accretion on an aerofoil for a 2 MW wind turbine.

Scanning tunneling microscopy (STM), X-ray photoelectron spectroscopy (XPS), and first principles theoretical calculations have been used to gain insight into the fundamental processes involved in the adsorption and self-assembly of oxalic acid on Cu(111). The experimental data demonstrate that several reaction pathways are involved in the chemisorption of oxalic acid on Cu(111), one of which lead

Epitaxial growth of heterostructure nanowires allows for the definition of narrow sections with specific semiconductor composition. The authors demonstrate how postgrowth engineering of III-V heterostructure nanowires using selective etching can form gaps, sharpening of tips, and thin sections simultaneously on multiple nanowires. They investigate the potential of combining nanostencil deposition

Objectives Clinical outcomes in the secondary prevention of cardiovascular disease depend on the patients' adherence to prescribed medicines. Motivational interviewing (MI) is a patient-centred approach used to change different health behaviours. The objective of this pilot study was to explore the impact of a clinical pharmacist's consultation on beliefs about medicines and self-reported medicati
