6. Gastric gland luminal pressure and mucosal protection : An in vivo study in the anesthetized rat
Sammanfattning : The driving force for creation of channels in gastric mucus, for acid and pepsin transport, ismost probably the hydrostatic pressure generated within the gastric gland lumen. The aim ofthis study was to investigate the origin and regulation of the glandular pressure. LÄS MER
7. Metal Release and Corrosion of Stainless Steel in Simulated Food Contact
Sammanfattning : Knowledge on metal release behaviour of stainless steels used in food processing applications and cooking utensils is essential within the framework of human health risk assessments. Recently, a new European test guideline (the CoE protocol) has been implemented to ensure safety of metals and alloys in food contact, such as stainless steels. LÄS MER
8. Evolution of the groundwater geochemistry in sulphide bearing tailings remediated by applying till cover, Kristineberg, Northern Sweden
Sammanfattning : At the Kristineberg mine in northern Sweden, sulphide-rich tailings were remediated in 1996 by applying till covers. The sulphides were isolated from the atmosphere to prevent oxidation. LÄS MER
9. Co-disposal of waste rock and lignite fly ash to mitigate the environmental impact of coal mining
Sammanfattning : Waste rocks (WRs) from coal mining and fly ash (FA) from coal combustion were studied to determine the potential of the WRs to generate AMD, FAs to neutralise it and estimate their impacts on environment. The ultimate goal was to develop a methodology based on co-disposal to mitigate the environmental problems associated to both wastes. LÄS MER
10. Helicobacter pylori : molecular insights into regulation of adhesion properties
Sammanfattning : Helicobacter pylori infects the human stomach and triggers an inflammatory response that damages the gastric tissue. This host-pathogen interplay has dire consequences as up to 20 % of infected individuals develop peptic ulcer disease or gastric cancer. LÄS MER
