21. Iron in Haem Biosynthesis. Structural Studies of Ferrochelatase and Frataxin
Sammanfattning : Ferrochelatase catalyses the synthesis of heme by inserting Fe(II) into protoporphyrin IX. The structure of ferrochelatase from yeast has been determined (2.4 Å). The structure is homodimeric with each of the monomer made up of two Rossmann type domains with an active-site cleft between them. LÄS MER
22. Measurements of Oscillator Strengths in Fe, Zr, Mo and Ce
Sammanfattning : Atomic data are needed in many different areas of science and technology. Examples of users are the astronomical community and the lighting industry. In this work, the purpose of the projects has been to produce reliable atomic data needed to solve specific astrophysical problems. LÄS MER
23. On the hot crack formation during solidification of iron-base alloys
Sammanfattning : Hot cracking during solidification is a severe problem inmany casting processes, for example in continuous casting.Combinations of low strength and low ductility of the materialat high temperatures and applied tensile stress can cause hotcracking. LÄS MER
24. Investigating the parameters that influence the behaviour of natural iron ores during the iron production process
Sammanfattning : In the iron production processes, sinters and pellets are mostly used as raw materials due to their consistency with respect to physical and chemical properties. However, natural iron ores, as mined, are rarely used directly as a feed material for iron processing. LÄS MER
25. Brownification of freshwaters - the role of dissolved organic matter and iron
Sammanfattning : The term brownification refers to the trend of increasing water color, i.e. the water becoming browner, which has been observed throughout the northern hemisphere over the last decades. Brownification has both ecological and societal implications. LÄS MER
