The effects of non-stoichiometry and isomorphic substitutions on the properties of some apatite-type compounds were investigated. These investigations were performed both in the fields of Portland cement chemistry and apatitic calcium phosphate-based biocements. Apatite compounds were synthesized by solid state methods and by hydrolysis of the reactant α-tricalcium phosphate (α-TCP). The materials

This dissertation deals with the rental relations in Malmö between 1880 – 1925. This period witnessed extensive changes in Swedish society, including on the housing market. Industrialization and the rapid pace of urbanization created the basis for a housing market with a strong speculative element. Tenement housing made its breakthrough in Malmö around the turn of the 20th century. New housing are

This paper describes a model for mobile radio channels that includes consideration of directions of arrival and is thus suitable for simulations of the performance of wireless systems that use smart antennas. The model is specified for 13 different types of environments, covering macro- micro- and picocells. In this paper, a hierarchy of modeling concepts is described, as well as implementation as

Interreligious dialogue and conversion are two intriguing components in understanding religion. A reading of George Lindbeck constitutes the starting point for a discussion in this paper. The dominant reading of Lindbeck is that he claims that traditions absorb the world. According to this reading of Lindbeck, religious traditions are isolated, and yet the one with the best capacity to assimilate

Våldsamma konflikter mellan landets ursprungsbefolkningar och myndigheterna har på senare tid skakat Kanada. Christer Lindberg ger här, med glimtar från indianbyar, förhandlingsbord, internatskolor och museer, en översikt av de kanadensiska indianerna och deras krav på erkännande, landrättigheter och självstyre. Social misär och fattigdom präglar det dagliga livet på indianreservaten och de som bo

A new law regarding child-maintenance was issued in Sweden in 1997. The main purpose of the reform was to make the system more cost-efficient, in order to minimise government expenditure. This was done by advocating a more individualised economic responsibility, as well as new rules for how to calculate maintenance levels. Almost five years later it is clear that the economic goals have not been

Popular Abstract in Swedish Teknisk textil är en bred benämning för textila material med användningsområden som inte är beklädnad eller där utseendemässiga krav oftast är av underordnad betydelse. På senare tid har dock designsynpunkter på tekniska textilprodukter kommit att alltmer uppmärksammas och detta belyses i kapitel 10 i avhandlingen. Teknisk textil är en nygammal industrigren som genomgåtIn this thesis the tensile strength, deformation, damage resistance and tear propagation for flexible composites are analysed. There are two essential requirements common to all flexible composites; namely, high tearing strength and good matrix-to-fabric adhesion. The interaction of fabric and matrix is complex. The most critical variables are those of yarn and fabric structure, the mechanical pro
