1. 6. Avvaktande eller aktiv handläggning vid långsam förlossningsprogress hos friska förstföderskor - En studie om riskfaktorer, obstetriskt utfall och förlossningsupplevelse

   Författare :Anna Dencker; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; randomised controlled trial; nulliparous women; slow labour progress; prolonged labour; oxytocin augmentation; operative delivery; risk factors; labour duration; multiple regression analysis; childbirth questionnaire; factor analysis; childbirth experience;

   Sammanfattning : Slow labour progress is common in nulliparous women and is associated with childbirth complications and negative birth experiences. Oxytocin augmentation is widely used to treat slow labour despite associated risks for the fetus. An ongoing debate concerns whether oxytocin should be administered directly or postponed after arrested labour. LÄS MER

3. 7. Dynamics of Vehicle-Deck Interactions

   Författare :Junbo Jia; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vehicle-deck interactions; Lightweight structure; Vehicle dynamics; Vibration analysis.; Lashing; Vehicle securing; Ship motions; Modal testing; Finite element analysis;

   Sammanfattning : The work presented in this thesis concerns the modelling and analysis of vehicle-ship deck interactions. The physical modelling of vehicles is discussed together with the modelling of supporting structures/ship decks, and the interactions between vehicles and supporting structures. LÄS MER

4. 8. Active Health Monitoring of Aerospace Composite Structures by Embedded Piezoceramic Transducers

   Författare :Christophe Paget; KTH; []
   Nyckelord :embedded; piezoceramic; piezoelectric; transducer; composite; structural; integrity; health monitoring; damage detection; Lamb waves; wavelets; normal-mode expansion; FE-method; SLMT;

   Sammanfattning : The objectives of the thesis work were to study theinteraction between embedded piezoceramic transducers andcomposite structures as well as determine techniques tosimplify the Lamb waves analysis. Firstly, this studyconsidered the design of the embedded piezoceramic transducers. LÄS MER

5. 9. Liv och arbete i pizzabranschen

   Författare :Henrik Hultman; Jeja-Pekka Roos; Linnéuniversitetet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; immigrant entrepreneurship; the pizza industry; life mode analysis; biographical method; insertion sequences; stratification; occupational status; entrepreneurship policy; integration policy; Sociology; Sociologi;

   Sammanfattning : This thesis unravels the pizza trade through a sociological inquiry into its history, its businesses, and its people. In Sweden, the typical pizza place is a small independent business, owned and operated by one or a few people with immigrant backgrounds. Hence, the trade is an immigrant small business niche.

7. 10. Structural and Spectroscopic Studies of Solvated Metal Ions

   Författare :Alireza Abbasi; Magnus Sandström; Ernö Brucher; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Coordination; Solvation; X-ray diffraction; EXAFS; IR; Raman; Normal coordinate analysis; trivalent metal ions; dmso; triflate; hydration; Chemistry; Kemi;

   Sammanfattning : Crystallographic and spectroscopic studies have been performed of structures, coordination and chemical bonding for series of trivalent metal ions solvated by two oxygen-coordinating solvents, water and dimethyl sulfoxide (DMSO). The hydrated scandium(III) and lanthanoid(III) ions, La to Lu, are surrounded by tricapped trigonal prisms of aqua ligands in the isomorphous series of trifluoromethanesulfonates, [M(H2O)n](CF3SO3)3.
