This thesis demonstrates the potential of the liquid membrane extraction technique as an alternative method for the analysis of trace ionisable organic compounds in the environment. Liquid membrane based extraction methods for the analysis of s-triazine herbicides and phenolic compounds were developed. Selectivity of the technique was demonstrated by extraction the above compounds in river water,

Boken handlar om den katolska kyrkan och den katolska minoriteten i Sverige, dess kulturella och religiösa identitet samt dess ställning i det svenska samhället i slutet av 1800- och början av 1900-talet. Jag anknyter till teorier och modeller som utvecklats inom kulturhistorisk och religionssociologisk forskning och har därvid särskilt tagit fasta på teorier om katolicismen som en motkultur i det

Popular Abstract in Swedish Internationalisering av högre utbildning beskrivs i första delen av avhandlingen i ett vidare perspektiv, flera olika forskningstraditioner som berör högre utbildning och internationalisering beskrivs i syfte att utgöra en bakgrund för argument som framhåller ett pedagogiskt och didaktiskt perspektiv som väsentligt i samband med utveckling och konkretisering av en interThe development of higher education in the Western countries involves ideas of internationalisation, included in curricular objectives. Policy-makers stipulate internationalisation ideologies, from a politico-economic perspective, where ideas about flows of various cultural elements are incorporated in visionary idealistic terms. Nevertheless teachers and students and others concerned with higher

Exact-diagonalization results for Kondo nanoclusters alloyed with mixed-valence impurities show that tuning the energy spacing Δ drives the system from the Kondo to the Ruderman-Kittel-Kasuya-Yosida (RKKY) regime. The interplay of Δ and disorder gives rise to a Δ versus concentration T=0 phase diagram very rich in structure. The parity of the total number of electrons alters the competition betwee

Industry--academia collaboration is critical for empirical research to exist. However, there are many obstacles in the collaboration process. This paper reports on the experiences gained by the author, in a 2-year collaboration project on software testing which involved on-site work by the researcher in the industry premises. Based on notes, minutes of meetings, and progress reports, the project h

To meet the demands of high electrical efficiencies in combination with low emissions for gas turbine-based power plants, wet cycles have gained new interest. The combustion chamber is a key component in such a power plant. Detailed investigations are necessary to gain insight into the formation of hazardous emissions such as CO and NOx. In this paper, computational fluid dynamics (CFD) has been e

There are many fashion words in AI, such as introspection, reflection, metalanguage, belief and intention. The usual way of looking at such concepts is proof theoretical even if it is not at all clear that these concepts can be described in a formal language. I shed light on some of these concepts from a semantical point of view, and show that it is impossible to describe them to a computer. This

Widespread availability of location aware devices (such as GPS receivers) promotes capture of detailed movement trajectories of people, animals, vehicles and other moving objects, opening new options for a better understanding of the processes involved. In this paper we investigate spatio-temporal movement patterns in large tracking data sets. We present a natural definition of the pattern 'one ob
