  2. 21. Knowledge creation and transfer in construction organisations in Tanzania

    Author : Harriet K. Eliufoo; Stellan Lundström; Per-Olof Sverlinger; KTH; []
    Keywords : Knowledge creation; knowledge transfer; construction organisations; process model; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

    Abstract : The project-based nature of construction organisations creates a learning opportunity from most of the activities carried by these organisations. Knowledge is being created in the course of carrying core and non-core activities in the organisation. For organisations to make the most of this knowledge, a mechanism for tapping has to exist.

    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; blast furnace chemistry; ironmak ing; thermodynamics; silicon compounds; combustion; fuel injection; mass balance; slags; pig iron; gases; droplets;

    Abstract : The thermodynamic conditions for the behaviour of silicon in the lower part of the blast furnace have been the focus of the thesis. More specifically, the influences of temperature, carbon activity, total gas pressure and Fe reoxidation on silicon have been studied. READ MORE

  5. 23. A Study on Selected Hot-Metal and Slag Components for Improved Blast Furnace Control

    Author : Annika Andersson; KTH; []
    Keywords : ;

    Abstract : The main objective of this work was to gain an increasedunderstanding of selected blast furnace phenomena which couldbe utilized for an improved blast furnace process control. Thisthesis contributes with both a model study and an experimentalstudy on blast furnace tapping, and results from these findingscan be used to enhance the control of the blast furnace. READ MORE

  6. 24. Study of Sulfide Capacity of Slag and Sulfur Removal from Hot Metal

    Author : Adolfo Firmino Timoteo Condo; Du Sichen; Robert Eriksson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metallurgical process science; Metallurgisk processvetenskap;

    Abstract : The present study aims at investigating the desulfurization process in hot metal and sulfide capacity of slags. The missing experimental data of sulfide capacities in Al2O3-CaOMgO-SiO2 system at 1713 K, 1743 K, 1773 K, 1823 K, 1873 K and in the Al2O3-CaO-SiO2 system at 1873 K were investigated under wellcontrolled oxygen potentials.

  7. 25. Precision in neuropsychology. Four challenges when using simplified assumptions

    Author : Jacob Stålhammar; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neuropsychology; practice effects; mild cognitive impairment; dementia; second language effects; bilingualism;

    Abstract : Cognition comprises all thought processes, from perception to memory. Neuropsychological tests are the gold standard (= best way) to measure cognition. However, clinical assessment may at times have to rely on simplified assumptions. READ MORE
