2. CVD on Iron Powder - Using Fluidising Bed Techniques
Abstract : Today's electrical energy conversion devices, such as motors, transformers, inductors and generators, are based on laminated magnetic cores for reduction of eddy current losses, imposing a two-dimensional magnetic flux distribution. Using a three-dimensional magnetic flux distribution while maintaining low magnetic losses requires new approaches to magnetic core materials. READ MORE

4. Iron losses during desulphurisation of hot metal
Abstract : After injection of calcium carbide and magnesium during desulphurisation of hot metal, the slag is normally solid and contains large amounts of iron. Besides the enclosed iron droplets in the slag, drawn-off hot metal during slag skimming also accounts for iron losses during desulphurisation of hot metal. READ MORE

5. Food habits in Swedish adolescents. Meal pattern, food choice and bioavailability of iron 1994 and 2000
Abstract : The general iron fortification of white wheat flour was removed after 50 years of iron fortification. It was considered important to evaluate the effects of withdrawal of iron fortification among vulnerable groups in the population. Adolescents have high iron requirements for growth and the girls for menstrual losses. READ MORE
