6. On the Microstructure and the Thermal Conductivity in Compacted Graphite Iron
Sammanfattning : Compacted graphite iron (CGI) is a cast iron material that has gained much attention due to its attractive material properties which are intermediate between those of grey and ductile cast iron. In the automotive industry compacted graphite iron has become an interesting alternative material to grey cast iron in components like cylinder blocks or cylinder heads. LÄS MER
7. On Thermal Conductivity and Strength in Compacted Graphite Irons : Influence of Temperature and Microstructure
Sammanfattning : Thermal conductivity, hardness and strength are all highly important material properties, affecting the performance and life expectancy of components operating at elevated temperatures. The main purpose of this work has been to increase the knowledge and understanding concerning how mechanical and physical properties are affected by temperature and microstructure in compacted graphite irons.

8. Influences of the Graphite Phase on Elastic and Plastic Deformation Behaviour of Cast Irons
Sammanfattning : 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. LÄS MER
9. Androgenic Effects of the Progestin Levonorgestrel in Three-spined Stickleback (Gasterosteus aculatus)
Sammanfattning : The extensive use of pharmaceuticals and their poor removal by wastewater treatment plants has led to the emergence of pharmaceutical compounds as global aquatic contaminants. Progestins, the synthetic analogues to progesterone, are receiving increasing attention as contaminants and have been shown to impair reproduction in fish and amphibians at low ng L-1 concentrations.

10. Progestagenic Aquatic Contaminants Act as Potent Androgens in Fish : Experimental Studies in Three-spined Stickleback and Zebrafish
Sammanfattning : The extensive use of pharmaceuticals and their poor removal by wastewater treatment plants has led to the emergence of pharmaceutical compounds as global aquatic contaminants. Progestins, the synthetic analogues to progesterone (P4), are receiving increasing attention as contaminants and have been shown to impair reproduction in fish and amphibians at low ng L-1 concentrations.
