The corrosion behaviour of two cobalt-based coatings (ULTIMET™ and STELLITE™ 6) with zero, 0.3 and 0.6 wt% ruthenium were studied and compared with two cobalt-based bulk alloys (ULTIMET™ and STELLITE™ 6B) in synthetic mine water (pH values of

When modern humans left Africa ca. 60,000 years ago (60 kya), they were already infected with Helicobacter pylori, and these bacteria have subsequently diversified in parallel with their human hosts. But how long were humans infected by H. pylori pri

In the context of global production, Africa as a continent is a very small producer of Pyrus communis pears, with roughly 3% of global hectares and production. South Africa produces 56% of Africa’s total crop, followed by Algeria (16%), Tunisia (11
