  1. 11. Brash Ice and Level Ice Growth, Effects of Snow

    Författare :Vasiola Zhaka; Andrzej Cwirzen; Kaj Riska; Robert Ettema; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; brash ice growth; level ice growth; snow effects; slush; snow ice; macroporosity; piece size distribution; Byggmaterial; Building Materials;

    Sammanfattning : Brash ice occurs due to frequent navigation in ice-infested waters, typically along established navigation tracks regularly maintained by icebreakers and harbors. The accumulation and consolidation of brash ice between two ship passages are influenced by meteorological factors including the cumulative freezing air temperatures, and the mechanical processes such as ice-breaking due to ship passages.

  3. 12. An Investigation of the Iron-Ore Wheel Damages using Vehicle Dynamics Simulation

    Författare :Saeed Hossein Nia; Sebastian Stichel; Matti Rantatalo; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; three-piece bogie; wear; RCF; prediction; traction; braking; heavy haul; simulation; Vehicle and Maritime Engineering; Farkostteknik;

    Sammanfattning : Maintenance cost is one of the important issues in railway heavy haul operations. For the iron-ore company LKAB, these costs are mainly associated with the reprofiling and changing of the wheels of the locomotives and wagons. The main reason for the wheel damages is usually surface initiated rolling contact fatigue (RCF) on the wheels. LÄS MER

  4. 13. Att bo med soffa : en möbels betydelse för bostadens planering och livet i hemmet

    Författare :Birgitta Mitchell; Institutionen för arkitektur och byggd miljö; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; participatory design; interior design; house design; gender; lifestyle; sofa; home; Architecture; dwelling; Arkitektur; inredningsarkitektur;

    Sammanfattning : Experiences of participatory design with full-scale modelling in three case studies form the basis of this work. When the participants in these studies visualised their dwellings there was a strong focus on the sofa. This piece of furniture is one of the most common in Swedish homes. It also requires much space. LÄS MER

  5. 14. Suppressor of zeste 12, a Polycomb group gene in Drosophila melanogaster; one piece in the epigenetic puzzle

    Författare :Anna Birve; Anssi Saura; Allen Shearn; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; Drosophila melanogaster; epigenetic; homeotic genes; Polycomb group; PRE; heterochromatin; Suppressor of zeste 12; chromatin silencing; Genetik; Clinical genetics; Klinisk genetik; Genetics; genetik;

    Sammanfattning : In multicellular organisms all cells in one individual have an identical genotype, and yet their bodies consist of many and very different tissues and thus many different cell types. Somehow there must be a difference in how genes are interpreted. So, there must be signals that tell the genes when and where to be active and inactive, respectively. LÄS MER
