1. 1. Material Hygiene : An EcoDesign mindset for recycling of products

   Författare :Jan Johansson; Conrad Luttropp; Stephen Evans; KTH; []
   Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : In recent years the end-of-life phase has come into focus. European Union directives have been issued regulating certain product groups and producer responsibility. Vehicles and electronic products are the first to be identified and targeted. EU environmental legislation acts as a driver for increased reuse, recycling and recovery. LÄS MER

3. 2. Recovery of iron and manganese values from metallurgical slags by the oxidation route

   Författare :Anna Semykina; Seshadri Seetharaman; Gabriella Tranell; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oxidation; metallurgical slag; recycling; FeO; iron recovery; manganese recovery; manganese ferrite; nano-ferrites; oxidation process; TTT; crystallization; kinetics studies; thermodynamic studies; modelling; cold-model studies; electromagnetic buoyancy force; Metallurgical process engineering; Metallurgisk processteknik; Metallurgical process and manufacturing engineering; Metallurgisk process- och produktionsteknik; Materials science; Teknisk materialvetenskap;

   Sammanfattning : In the modern practice, a sustainable development strategy in a domain of wasteutilization is shifting its focus from a general completeness of recycling to a morespecific attention to efficiently utilize elements in the wastes. This is well-illustrated bythe steelmaking slag industries. LÄS MER

4. 3. Sustainable management of dredged sediments : potential recovery of valuable compounds

   Författare :Laura Ferrans; William Hogland; Monica Odlare; Linnéuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dredged sediments; nutrients; metals; speciation; recovery; characterisation; beneficial use; life cycle assessment; extraction; plant-growing substrate; circular economy; Miljövetenskap; Environmental Science;

   Sammanfattning : Dredging of sediments occurs worldwide to increase water depth in harbours, bays, lakes and rivers, as well as to recover aquatic ecosystems. Landfilling and open-ocean discharge are traditional disposal routes for dredged material. However, the methods are restricted by environmental and legal concerns. LÄS MER

5. 4. Managing the contradictions : Recovery from severe mental disorders

   Författare :Alain Topor; Anders Bergmark; John Strauss; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychosis; severe mental disorder; schizophrenia; recovery; users perspective; Social work; Socialt arbete; Social Work; socialt arbete;

   Sammanfattning : One of the assumptions made when mental problems are defined as a medical problem is that certain problems, certain diagnoses, are chronic. Nevertheless, a substantial number of follow-up studies have shown that the course of development in patients with these diagnoses is neither uniform nor chronic. LÄS MER

7. 5. Microstructure and property models of alloy 718 applicable for simulation of manufacturing processes

   Författare :Marie Anna Moretti; Lars-Erik Lindgren; Paul Åkerström; Jörgen Kajberg; Bijish Babu; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Material characterisation; Material modelling; Alloy 718; Plasticity; Recrystallization; Hållfasthetslära; Solid Mechanics;

   Sammanfattning : This thesis focuses on experimental characterization, understanding and modelling of nickel-based alloy 718, for a large range of loading conditions. Alloy 718 is the most widely used nickel-based superalloy, due to its high strength, high corrosion resistance and excellent mechanical properties at high temperatures. LÄS MER
