1. 6. The economics of residual waste : policies, price discrimination, and welfare

   Författare :Sef Meens-Eriksson; David Granlund; Runar Brännlund; Thomas Broberg; Raymond Gradus; Umeå universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Waste economics; net social cost analysis; waste incineration; municipal waste policy; waste taxes; price discrimination; spatial competition; welfare effects; Economics; nationalekonomi;

   Sammanfattning : Paper [I]: In this study, a net social cost framework is applied to provide insights on policy issues relating to the cross-border trade in waste fuel. We estimate the net social cost of using imported waste fuel in a highly efficient combined heat and power plant (CHP) in a cold climate by considering both private costs and benefits as well as external costs related to energy production, alternative waste management and fuel transport.

3. 7. Tailored process gases for laser powder bed fusion

   Författare :Camille Nicole Géraldine Pauzon; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Helium; Laser powder bed fusion; AM process productivity; Spatter particles; Residual oxygen; 316L stainless steel; Argon; Nitrogen; Additive manufacturing; Process atmosphere; Process stability; Residual stresses.; Ti-6Al-4V; Alloy 718;

   Sammanfattning : Metal laser powder bed fusion (L-PBF) allows for production of complex components using the energy from a laser to locally melt micron-sized powder following a layer-wise approach. Considerable scientific efforts are focused on addressing the influence of the process parameters on the melting stability and the control of material properties, while developing necessary monitoring and characterization tools.

4. 8. Minnets spelrum : Om musik och pensionärskap

   Författare :Sverker Hyltén-Cavallius; Mats Hellspong; Owe Ronström; Alf Arvidsson; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Pensionerhood; sound; music-making; memory; narrative; mode; practice; place; utopics; generation; age; nostalgia; aesthetics; interface; timespace; chronocity; structure of feeling; organizations; artists; institutions; Ethnology; Etnologi;

   Sammanfattning : The aim of this study is to explore how pensionerhood is formed through music-making. What are the building blocks of pensionerhood in musical contexts, and which values are included and excluded? In the study pensionerhood is defined in terms of cultural position, the term forming is used to define conditioning, limiting and enabling forces and the term music-making denotes a wide set of activities from arranging venues to performance.

5. 9. Numerical investigation on the formation mechanism of residual stress in metal cutting

   Författare :Yang Liu; Industriell Produktion; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Residual stress; FEM; ; Metal cutting; Thermal-mechanical load; Plastic deformation;

   Sammanfattning : Residual stress can be introduced unintentionally into the workpiece with various magnitudes and distributions through all manufacturing processes. These stresses have a significant effect upon the performance of the final component. LÄS MER

7. 10. Hard Turning of Bearing Steels. Controlling residual stress and improving fatigue life

   Författare :Michael Jacobson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; x-ray diffraction; bearing steel; residual stress; fatigue life; cutting conditions; hard turning;

   Sammanfattning : There are many different precision mechanical components such as bearings, fuel injectors, gears and hydraulic components, which are made of hardened steels, and have to be machined to a high degree of precision. Traditionally these components are being ground. LÄS MER
