Research interests: understanding how the malaria parasite deals with the large influx of haem associated with ingestion and degradation of haemoglobin in its digestive vacuole and the effects of antimalarials such as chloroquine, Major Research Groupings | Institute Of Infectious Disease and Multi-investigator groups: Extramural research units of the South African Medical Research Council: Precision and Genomic Medicine. Molecular Mycobateriology FA20E and FA20F Subaru Engines - australiancarews The FA20E and FA20F engines have a cast aluminium alloy cylinder head with chain-driven double overhead camshafts per cylinder bank. The four valves per cylinder – two intake and two exhaust – were actuated by roller rocker arms which had built-in needle bearings that reduced the friction that occurred between the camshafts and the roller rocker arms.
