We highlight some results from our high-resolution spectroscopic elemental abundance survey of F and G dwarf stars in the solar neighbourhood.

The poet and bishop Esaias Tegnér did not write any hymns, but he admired very much the hymns of his contemporary author colleagues, especially those of J. O. Wallin. In some of his poems, hymnsinging and organ music are motifs. As a bishop, he made efforts to spread the use of the hymnal of 1819.

In a pulsed UWB system, either coherent receivers or transmit-reference (TR) receivers can be used to demodulate the signals. For coherent receivers, which are typically based on a Rake Structure, the large number of resolvable multipaths is a major challenge for channel estimation and receiver complexity. TR receivers can effectively collect energy from all the received multipath components with

Urban Squares suggests a specific and fresh take on agorology – the study of urban squares. The approach is one of recording everyday life and focusing on different ways to describe and investigate the public life and space of urban squares. The book comprises four empirical case studies of squares focusing especially on the urban material culture and spatio-temporal changes of these squares. The

Earlier research on collaboration shows that cooperation comprises problems and conflicts. The purpose of this study is to describe successful collaboration even if it unfolds during shorter interaction frequencies. In the article, interactive patterns involved in the construction of these phenomena will be analyzed. Forming the empirical basis for this study are 119 field observations of organize

Baylor and collaborators have demonstrated (Baylor & Plant, 2005; Baylor et. al., 2006) that the use of virtual pedagogical coaches portrayed as young and attractive women can increase the willingness of female students to apply for technical education and to help increase their selfefficacy. Pedagogical processes such as role modelling and identification seem to be involved (cf. Bandura, 1977

The pebble game on AND/OR dags which is natural generalization of a well known pebble game on dags is considered. The following problem is given: if k pebbles are enough to place a pebble on a given vertex of an AND/OR dag. It is shown that the problem is log-space complete for languages accepted in polynomial space.

Over the past years, natural catastrophes have disrupted society: the tsunami in December 2004, hurricane Katrina in the Gulf of Mexico, the earthquakes in Pakistan in 2005, causing massive material destruction and human suffering. In addition, technological accidents in transport, energy and process industry undermine the public faith in risk management, while the uncontrolled spreading of diseas
