  2. 6. Intra-industry trade: measurements, determinants and growth : a study of Swedish foreign trade

    Author : Pär Hansson; Lars Lundberg; David Greenaway; Örebro universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Intra-industry trade; determinants; comparative costs; factor intensity; product differentiation; elasticity of substitution; economies of scale; quasi-homothetictastes; Sweden; Economics; Nationalekonomi;

    Abstract : The conclusions are that a traditional factor proportions model seems neither theoretically nor empirically to explaing IIT. However, a relaxation of the assumption of homogeneous products in an industry gives rise to several implications for IIT. READ MORE

  4. 7. Aspects of health-related quality of life : Associations with psychological and biological factors, and use as patient reported outcome in routine health care

    Author : Evalill Nilsson; Margareta Kristenson; Mitra Unosson; Marianne Carlsson; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicin;

    Abstract : Background Health-related quality of life (HRQoL) is increasingly recognised as an important patient-reported outcome in health care research. However, the use is still restricted and several questions remain about the value and feasibility of using measures of HRQoL in routine health care. READ MORE

  5. 8. Sensorimotor function in chronic neck pain : objective assessments and a novel method for neck coordination exercise

    Author : Ulrik Röijezon; Mats Djupsjöbacka; Martin Björklund; Charlotte Häger-Ross; Dario Liebermann; Mikael Karlberg; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neck pain; Whiplash; Sensorimotor; Motor Control; Motor Learning; Neck Coordination Exercise; Postural Control; Cervical kinematics; Reliability.; Community medicine; Samhällsmedicin; rehabiliteringsmedicin; Rehabilitation Medicine;

    Abstract : Chronic neck pain is a widespread problem that causes individual suffering as well as large costs for the society. The knowledge about the pathophysiology is poor and therefore specific diagnosis and causal treatment are rare. READ MORE

  6. 9. Development of Structural Steels for Powder Bed Fusion - Laser Beam

    Author : William Hearn; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tensile properties; in situ tempering; process development; martensite; additive manufacturing; cold cracking; low-alloy steel; structural steel; powder bed fusion – laser beam; carbon steel;

    Abstract : Over the past decade, powder bed fusion – laser beam (PBF-LB) has attracted noticeable attention from both academia and industry. However, there remains a scarcity of approved material for the process, as fewer than 40 alloys are commercially available. READ MORE

  7. 10. Increased Productivity of Ferrous Alloys Produced by Powder Bed Fusion - Laser Beam

    Author : Rasmus Gunnerek; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; additive manufacturing; process optimization; build rate; build speed; powder bed fusion – laser beam; porosity; low alloy steel; 316L stainless steel; productivity in AM;

    Abstract : Low production speeds limit wider adoption of powder bed fusion – laser beam (PBF-LB) in cost sensitive industries as it correlates directly with high production costs. The main process parameters such as scan speed, hatch distance and layer thickness can be scaled up to increase build speed, but it often comes at a trade off in lower quality, i. READ MORE
