  1. 1. Performance of Construction Projects : Essays on Supplier Structure, Construction Costs and Quality Improvement

    Author : Abukar Warsame; Hans Lind; Roine Leiringer; KTH; []
    Keywords : ;

    Abstract : The performance of the construction industry and its contribution to the welfare of society in comparison to other industries such as the manufacturing industry has lately been the focus of many commissioned reports and academic research publications. The so-called “iron triangle” of time, cost and quality have been the most important metrics of construction project performance, especially for the selection of appropriate procurement methods.

  2. 2. Gene : on the origin, function and development of sedentary Iron Age settlement in northern Sweden

    Author : Per H. Ramqvist; Umeå universitet; []
    Keywords : HUMANIORA; HUMANITIES; sedentary; settlement; colonization; internal development; origin; development; three-aisled long-houses; house construction; room division; inter-regional structure; iron forging; bronze casting; Järnåldern;

    Abstract : This thesis deals with questions concerning the sedentary settlement in central Norrland: its origins, function and development. This type of settlement appears at the start of our calendar. The material comprises an almost fully excavated farmstead from the Early Iron Age (1-600 A.D. READ MORE

  3. 3. Influences of the Graphite Phase on Elastic and Plastic Deformation Behaviour of Cast Irons

    Author : Torsten Sjögren; Ingvar L. Svensson; Sten Johansson; Jorge Sikora; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cast iron; Flake graphite; Compacted graphite; Spheroidal graphite; Elastic deformation; Plastic deformation; Modulus of elasticity; Graphite modulus of elasticity; Strength coefficient; Strain hardening exponent; Acoustic emission; Construction materials; Konstruktionsmaterial;

    Abstract : The amount and morphology of the graphite phase largely controls the resulting properties of cast iron. For instance, in flake graphite cast irons the mechanical properties are low while the thermal conductivity is high. READ MORE

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

    Author : Anna Semykina; Seshadri Seetharaman; Gabriella Tranell; KTH; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 5. Landscapes of Technology Transfer : Swedish Ironmakers in India 1860–1864

    Author : Jan Af Geijerstam; KTH; []
    Keywords : HUMANIORA; HUMANITIES; History of technology; industrial heritage studies; industrial archaeology; technology transfer; diffusion; technological systems; landscapes of technology; iron and steel; charcoal iron; direct and indirect ironmaking; bloomeries; 19th century; indu; Historiska studier av teknik; vetenskap och miljö; History of Science; Technology and Environment;

    Abstract : In the early 1860s three Swedes, Nils Wilhelm Mitander,Julius Ramsay and Gustaf Wittenström, were engaged by theBritish to build and run charcoal-based ironworks in India.These works, the Burwai Iron Works of the British Government inthe case of Mitander and the privately owned Kumaon Iron Worksin the case of Ramsay and Wittenström, were both to bebased on the most modern European technology.
