  1. 1. Människor och kvarts : sociala och teknologiska strategier under mesolitikum i östra Mellansverige

    Författare :Christina Lindgren; Anders Carlsson; Kjel Knutsson; Arne Johan Naeröy; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Mesolitikum; stenteknologi; Archaeology subjects; Arkeologiämnen;

    Sammanfattning : This thesis deals with the social dimension in lithic technology during the Mesoltihic in eastern central Sweden. The starting point is the empirical observation of the disappearing bipolar-on-anvil method of reduction around 4500 BC. LÄS MER

    Författare :Mattias Sjölander; Philip I. Buckland; Johan Linderholm; Peter Jordan; Umeå universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; archaeology; hunter-gatherer; spectroscopy; chemometrics; quartz; quartzite; bifacial; lithics; geoarchaeology; exploratory; spatial analysis; modelling; arkeologi; jakt- och fångstfolk; spektroskopi; kemometri; kvarts; kvartsit; bifacial; flathuggen; geoarkeologi; rumslig analys; modellering; Archaeology; arkeologi; environmental archaeology; miljöarkeologi;

    Sammanfattning : In this thesis an exploratory approach has been used to study settlement and mobility among hunter-gatherer societies in Northern Sweden during the 2 000 – 0 BC period. The focus has been on developing the topics of bifacial point use and raw material management of quartzand quartzite materials. LÄS MER

  5. 4. Riskabla samtal : en analys av potentiella faror i skolans kvarts- och utvecklingssamtal

    Författare :Johan Hofvendahl; Jan Anward; Anna Lindström; Linköpings universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Parent-student-teacher conference; conversation analysis; strategy; risk; Kvartssamtal; utvecklingssamtal; samtalsanalys; strategi; risk; Languages and linguistics; Språkvetenskap; Sociology;

    Sammanfattning : In this thesis, conversation analysis (CA) is applied to study “risk strategies” in parent-teacher-student conferences in the Swedish nine-year compulsory school. The material consists of 80 conferences collected at two different points in time: 45 from the period 1992–93 (at that time called kvartssamtal, lit. LÄS MER

  7. 5. Aqueous behaviour of characteristic molecules in the synthesis of porous silica materials : - an atomistic description

    Författare :Emelie Nilsson; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; porous silica; struture directing agents; 29Si-NMR; neutron scattering; empirical potentail structure refinement; micelles;

    Sammanfattning : The formation process of porous silica materials is an intricate process, involving a number of components that interact to form a highly organized material. Both zeolites and mesoporous silica materials typically require the presence of organic structure director agents (SDAs) around which the silica network polymerizes. LÄS MER
