Nitrogen-fixingAnabaena cylindrica cells are found to evolve hydrogen in high quantities in the presence of CO plus C2H2. Studies with the inhibitors dichlorophenyldimethylurea (DCMU), disalicylidenepropanediamine (DSPD), dibromothymoquinone (DBMIB), undecylbenzimidazole (UDB) and chloro-carbonyl-cyanide-phenylhydrazone (CCCP) and also withAnabaena grown on(More)
Nitrogen fixation in Azospirillum brasilense is regulated at transcriptional and post-translational levels. Post-translational control occurs through the reversible ADP-ribosylation of dinitrogenase reductase (Fe Protein), mediated by the dinitrogenase reductase ADP-ribosyltransferase (DraT) and dinitrogenase reductase glycohydrolase (DraG). Although the(More)
As field determinations take much effort, it would be useful to be able to predict easily the coefficients describing the functional response of free-living predators, the function relating food intake rate to the abundance of food organisms in the environment. As a means easily to parameterise an individual-based model of shorebird Charadriiformes(More)
We present infrared imaging of a sample of 11 hot spots in the lobes of powerful radio galaxies. We have detected infrared counterparts to the hot spots in 3C 20West, 3C 33 South, 3C 111East and 3C 303West all of which have known optical counterparts as well. In addition, we detected the radio jet of 3C 303 in the near infrared. Four other hot spots, those(More)
BACKGROUND Occurrences of strokes often result in unilateral upper limb dysfunction. Dysfunctions of this nature frequently persist and can present chronic limitations to activities of daily living. METHODS Research into applying virtual reality gaming systems to provide rehabilitation therapy have seen resurgence. Themes explored in stroke rehab for(More)
The focus of this research was to investigate whether video game play reframed into the context of cumulative stress could play a moderating role on externalising behavioural outcomes. A sample of 14-15 year old adolescent boys (N = 197) were administered self-report measures relating to video game use, cumulative stress and externalising behaviours.(More)

This article featured nurse Betty Seunarine and her efforts as a health care teacher in the Dominican Republic. She fulfilled a dream by accepting a temporary volunteer placement through the Medical Group Missions. She found the work invigorating and arranged to come back in a year for a much longer placement. She lived in a guest house at Santana(More)
1. Two ferredoxin-type iron-sulfur proteins have been isolated from Mycobacterium flavum 301 grown under nitrogen-fixing, iron-sufficient conditions. No flavodoxin was observed. 2. These ferredoxins are apparently soluble: they were present in the supernatant fraction after disrupting by decompression. Only small amounts were present in particulate(More)
