In this work the intermetallic systems formed by transition-metals from group 5 to 9 with Ga, In and Zn have been experimentally and theoretically studied in detail. Syntheses, compositional analyses, X-ray and neutron diffraction (single crystal as well as powder) and measurements of physical properties, e.g. magnetic susceptibility and resistivity has been made for all compounds. Electronic-stru
Software Engineering has been a fundamental part of many computing undergraduate courses for a number of years. Although many of the tools and techniques used to undertake software engineering have changed, the assessment has typically stayed the same. Students are commonly tasked with producing a number of software artefacts, for example designs using the Unified Modelling Language (UML). We rece
Interactions between antioxidant-impregnated low-density polyethylene (LDPE) and polypropylene (PP), and oxygen-sensitive foods have been investigated. BHT and a-tocopherol are two antioxidants commonly used in both foods and polymers. In general, BHT was rapidly lost from LDPE film in contact with various foodstuffs. a-Tocopherol was completely retained in PP film, but some losses, although less
A large majority of teachers in Swedish 9-year compulsory schools and upper secondary schools find their work very meaningful, although they complain of serious problems in their work environment, especially on the psychosocial level. In the last 10–15 years, school has become one of Sweden’s major problem areas as far as the work environment is concerned. This applies to the work environment of b
