21. Role of nanopowder as sintering aid in the densification of water atomized ferrous powder
Sammanfattning : Press and sinter powder metallurgy (PM) steels are cost-effective solutions for structural applications. There is a constant drive for the improvement in the density of these PM steels which helps in expanding their usage in applications demanding higher performance than what they deliver today. LÄS MER
22. Heart failure and anemia in Sub-Saharan Africa : etiology, characterization, prognosis and the role of oral iron : experiences from Tanzania
Sammanfattning : Background: Heart failure remains unexplored in sub-Saharan Africa. Comorbidities such as anemia and iron deficiency are common and associated with increased mortality. Oral iron supplementation may be feasible in heart failure in countries with limited health care resources. Objectives: 1. LÄS MER
23. Genomics, physiology and applications of cold tolerant acidophiles
Sammanfattning : Psychrotolerant acidophiles have gained increasing interest because of their importance in biomining operations in environments where the temperature falls well below 10°C during large parts of the year.Acidithiobacillus ferrivorans is the only characterized acidophile with the ability to live a psychrotrophic lifestyle and is able to oxidize ferrous iron and inorganic sulfur compounds at low temperature.

24. The oxidative stress response of Francisella tularensis
Sammanfattning : Francisella tularensis is capable of infecting numerous cell types, including professional phagocytes. Upon phagocytosis, F. tularensis resides within the phagosome before escaping into the cytosol to replicate. Phagocytes constitute a hostile environment rich in ROS, which are employed as a means of killing pathogens. LÄS MER
25. Physiology and Genetics of Acidithiobacillus species : Applications for Biomining
Sammanfattning : Bacteria from the genus Acidithiobacillus are often associated with biominingand acid mine drainage. Biomining utilises acidophilic, sulphur and ironoxidising microorganisms for recovery of metals from sulphidic low grade oresand concentrates. LÄS MER
