  2. 1. Nanopowder as sintering aid for water-atomized ferrous powder

    Author : Swathi Kiranmayee Manchili; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; master sintering curve; dilatometry; reduction kinetics; thermal analysis; compaction; nanopowder; surface oxide; hydrogen; sintering; water-atomized iron powder; water-atomized steel powder;

    Abstract : Press and sinter powder metallurgy steels are cost-effective solutions for structural applications. There is a constant drive for improvement in the density of these powder metallurgy steels to expand their usage in high-performance applications. READ MORE

  4. 2. Computer-assisted surgery in children

    Author : Magnus Anderberg; Lund Pediatrik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; minimally invasive; learning curve; laparoscopy; fundoplication; da Vinci® Surgical System; costs; Children; computer-assisted; paediatric surgery; robot; robotic surgery;

    Abstract : Although positive in terms of patient trauma and recovery time, minimally invasive surgery has several technical drawbacks compared with open surgery. The new da Vinci® Surgical System from Intuitive Surgical® offers technical innovations aiming at overcoming these drawbacks and at improving the surgeon’s operating skills, such as the improved 3-D vision, tremor reduction and flexible instruments with a more natural and intuitive range of motion.

  5. 3. Progression and Regression. Aspects of Advanced Swedish Students' Competence in English Grammar

    Author : Monica Karlsson; Engelska; []
    Keywords : HUMANIORA; HUMANITIES; Engelska språk och litteratur ; English language and literature; error gravity; proper noun; identification frame; genericness; the zero article; ‘idiomatic’ prepositional use; ‘systematic’ prepositional use; ‘basic’ prepositional use; non-contiguous subject-verb construction; contiguous subject-verb construction; subject-verb concord; fossilisation; restructuring of information; automatisation; interlanguage; cognitive second language acquisition theory; U-curve development; regression; progression; developmental pattern; relative frequency; error score; potential error; developmental continuum; advanced learner; Grammar; semantics; semiotics; syntax; Grammatik; semantik; semiotik; Applied linguistics; foreign languages teaching; sociolinguistics; Tillämpad lingvistik; undervisning i främmande språk; sociolingvistik;

    Abstract : This thesis investigates advanced Swedish students’ development of three grammatical phenomena: subject-verb concord, prepositions and article use in compositions and translations. In order to describe the students’ development of these categories, actual errors are related to potential errors forming so called ‘error scores’. READ MORE

  6. 4. Testing palaeomagnetic and 14C based geochronological methods in the Baltic Sea

    Author : Bryan Lougheed; Kvartärgeologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; coastal; geochronology; palaeomagnetic secular variation; PSV; radiocarbon; 14C; reservoir age; R t ; ΔR; salinity; δ18O; geomagnetic field; Holocene; deglacial; Fennoscandia.;

    Abstract : The Baltic Sea is a continental shelf sea that is influenced by both river runoff and marine water. The two water masses are vertically stratified in the Baltic Sea, resulting in a positive, estuarine circulation system, which has undergone changes in the past due to isostatic uplift of the Baltic basin.

  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
