  1. 1. Laboratory method for the study of moisture-induced waviness in paper

    Författare :Cecilia Land; Göran Ström; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; method; moisture; paper; paper web; wavelength; waviness; Cellulose and paper engineering; Cellulosa- och pappersteknik; Chemical Engineering; Kemiteknik;

    Sammanfattning : Paper that is subjected to moisture undergoes dimensional changes. It expands during moistening and shrinks during drying. When the paper is under tension between rollers, the effects are complex since shrinkage and expansion are restricted in the width direction. Waves can then appear on the paper web. LÄS MER

  2. 2. The Lie of the Land: Gender, Farm Work, and Land in a Rural Vietnamese Village

    Författare :Cecilia Bergstedt; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Anthropology; Vietnam; gender; agriculture; farming; wet-rice cultivation; farm work; division of labour; land; land access; place;

    Sammanfattning : This anthropological study investigates ways in which perceptions of gender intersect with the everyday dealings of land and farming practices in a village in the northern part of Vietnam. The point of departure for this study is a desire to take a closer look at how processes of gendering actually take place and become meaningful on a day-to-day basis. LÄS MER

  3. 3. Baggy paper webs : Effect of uneven moisture and grammage profiles in different process steps

    Författare :Cecilia Land; Lennart Stolpe; Kaarlo Niskanen; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bagginess; drying; calendering; grammage; moisture content; paper; profile; reels; softwood kraft pulp; storage; strain; tension; web; Chemical Engineering; Kemiteknik;

    Sammanfattning : One of the problems encountered in paper converting is caused by the occurrence of "baggy webs", which essentially is when the tension profile of the paper web is uneven. In an area with low tension the paper is longer, which results in bagginess. LÄS MER

  4. 4. Encountering Environments. Natural conditions for subsistence and trade at Monte Polizzo, Sicily, 650-550 BC

    Författare :Cecilia Sandström; Göteborgs universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Ancient Sicily; Western Sicily; Monte Polizzo; Elymian; Indigenous; Iron Age; Archaic; Ancient environment; Archaeology; Geoarchaeology; Landscape Archaeology; Ecology; Geomorphology; Rivers; Ancient navigability; Subsistence; Land use; Trade; Trade routes; Transport amphorae; Connectivity; Household economy; Palynology; Exchange; Selinus; Motya; Segesta;

    Sammanfattning : The overall aim of this thesis is to deepen our knowledge about indigenous western Sicilians commonly called the Elymians and, ultimately, to recognise them as independent actors in Sicilian history. A vital part of this endeavour is to assess the Elymian role in regional trade and to evaluate the subsistence challenges they faced. LÄS MER

  5. 5. Spatial distribution of snow in Antarctica and other glacier studies using ground-penetrating radar

    Författare :Cecilia Richardson-Näslund; Robert W. Jacobel; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; GPR; ground-penetrating radar; radar soundings; snow accumulation; accumulation rate; spatial variability; Antarctica; Dronning Maud Land; cold surface layer; thermal regime; glacial cirques; Sweden; Antarktis; Glaciärer; Ackumulering av snö; Geography; Physical Geography; geografi med naturgeografisk inriktning;

    Sammanfattning : The overall aim of this thesis is to develop and exemplify the use of ground-penetrating radar (GPR) within the field of glaciology. The main focus is on the spatial distribution of snow in Dronning Maud Land, East Antarctica. LÄS MER
