  2. 1. Reef biostromes and related facies from the Middle Silurian of Gotland, Sweden

    Author : Olof Sandström; Geologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; physical geography; Geology; stromatoporoids; facies analysis; palaeobiology; Reefs; biostromes; Geologi; fysisk geografi;

    Abstract : Reef biostromes and related facies from the upper part of Wenlock and from Ludlow were investigated in order to account for their formation, their palaeoecology and biology. In the Hemse Group of Ludlow age, all studied biostromes comprise a low diversity fauna where one or few species dominates. READ MORE

    Abstract : Background Mass screening for celiac disease (CD) as a public health intervention is controversial. Before implementation, a suitable screening strategy should be outlined, and the acceptability of the screening scrutinized. Also, the benefits of early detection and possible negative consequences should be explored and compared. READ MORE

  7. 5. Fracture toughness properties of duplex stainless steels

    Author : Henrik Sieurin; Rolf Sandström; Jan-Olof Nilsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; duplex stainless steel; fracture toughness; austenite reformation; sigma phase; material optimisation; Materials science; Teknisk materialvetenskap;

    Abstract : Good toughness properties in base and weld material enable the use of duplex stainless steels (DSS) in critical applications. DSS offer high strength compared to common austenitic stainless steels. READ MORE
