1. 1. Some aspects on the reduction of olivine pellets in laboratory scale and in an experimental blast furnace

   Författare :Jerker Sterneland; KTH; []
   Nyckelord :Olivine; pellets; pellet testing; reduction softening melting; MPBO; blast furnace; reduction; quenching; dissection; coating; sticking; coated pellets;

   Sammanfattning : The reduction behaviour of the olivine iron ore pellet MPBOwas studied in laboratory scale at KTH as well as in the LKABexperimental blast furnace. Initially, a newreduction-under-load, or so-called reduction/softening/melting,test equipment was developed. LÄS MER

3. 2. Fabrication and Testing of Doped Uranium Nitride as an Accident Tolerant Fuel Alternative

   Författare :Luis Guillermo Gonzalez Fonseca; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; internal gelation; density; Uranium nitride; sintering; microspheres; doping; waterproofing.; ATF;

   Sammanfattning : Nuclear energy is a carbon-free energy source often considered less harmful to the environment than fossil fuels. However, accidents have shown that there are some safety concerns regarding nuclear energy that need to be continuously assessed and further improved. LÄS MER

4. 3. Molecular diagnostic methods for Mycobacterium avium subsp. paratuberculosis : more than a gut feeling

   Författare :David Herthnek; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Sammanfattning : Mycobacterium avium subsp. paratuberculosis (MAP) is the causative agent of the chronic enteric disease paratuberculosis in ruminants that causes considerable economic losses worldwide. Due to rigorous control measures, paratuberculosis is rare or absent in Sweden. However, import-related outbreaks have occurred. LÄS MER

5. 4. Towards a Better Understanding and Control of Factors Affecting the Physical Quality of Fish Feed

   Författare :Julia Wolska; Bioteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fish Feed; Physical quality; Durability; Aging; Crosslinking; Transglutaminase;

   Sammanfattning : As aquaculture expands, the volume of fish feed produced and transported must also increase. Therefore a better understanding and increased control of the factors that influence the physical quality of feed pellets is required. To achieve this goal, reliable methods measuring the physical quality of feed are needed. LÄS MER

7. 5. Recycling of metallurgical by-products within integrated iron and steelmaking : experimental studies of cold bonded by-product pellets

   Författare :Ryan Robinson; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

   Sammanfattning : In recent years as costs for depositing dust and sludge generated in the iron and steel making industry have increased, due to lack of space and increasing environmental restrictions, the need to recycle these solid by- products to avoid depositing costs and to recover valuable metal fractions, is soon becoming a necessary reality. Cold bonded agglomeration is considered to be a well-suited alternative for recycling of steel industry by-product dust and sludge. LÄS MER
