  1. 1. A study of the fatigue behaviour of laser and hybrid laser welds

    Author : Md. Minhaj Alam; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Manufacturing Systems Engineering; Produktionsutveckling;

    Abstract : This licentiate thesis focuses on the fatigue cracking behaviour of laser and hybrid laser-MAG welded structures. Beside the welding process and the resulting weld, several topics related to fatigue of welded structures are treated such as; macro and micro surface geometry, weld defects and their influence on fatigue performance of welded structures, fatigue analysis by the nominal and effective notch stress method, fatigue life prediction using LEFM (Linear Elastic Fracture Mechanics), fatigue testing, metallurgical analysis, elastic and elastic-plastic finite element analysis.

    Abstract : Internationalization of small and medium-sized enterprises (SMEs) has been a considerable concern for international business (IB) scholars. Particularly, for those economies such as Sweden with small local markets, internationalization of SMEs could be fundamental. READ MORE

  3. 3. Wnts in development : Focus on midbrain

    Author : Emma Rakel Andersson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Abstract : Studies in the field of embryonic development reveal the temporal and spatial requirement of specific genes/proteins in the formation of a given tissue. The specific knowledge of which genes/proteins regulate development of the ventral midbrain (VM) provides a guideline for the in vitro differentiation of specific cell types therein, such as dopaminergic (DA) neurons.

  4. 4. Additive Manufacturing of Ti-6Al-4V: Relationship between Microstructure, Defects and Mechanical Properties

    Author : Pia Åkerfeldt; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Materials; Materialteknik;

    Abstract : Additive manufacturing (AM) is a relatively new technology that is labelled to be innovative, disruptive, near-net shaping, enabling manufacturing of complex and customised products, for limitless number of applications, directly from the CAD model into real physical parts. For titanium alloys in aerospace applications, AM moreover stands for a reduced material cost, but also for large challenges when considering consistency and qualification of material properties and components in serial production.

  5. 5. Bruton tyrosine kinase in immunodeficiency and in B-cell malignancy

    Author : Qing Wang; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP;

    Abstract : BTK inhibitors have induced high response rates in the treatment of leukemias and lymphomas. Ibrutinib is the first-in-class US Food and Drug Administration (FDA)-approved BTK covalent inhibitor to treat chronic lymphocytic leukemia (CLL). However, a sub-group of patients develops resistance to ibrutinib therapy. READ MORE
