In this study we assessed the impact of climate variability on the Ross River virus (RRv) transmission and validated an epidemic-forecasting model in Cairns, Australia. Data on the RRv cases recorded between 1985 and 1996 were obtained from the Queensland Department of Health. Climate and population data were supplied by the Australian Bureau of Meteorology and the Australian Bureau of Statisti...

The parasitic nematode Ancylostoma ceylanicum is common in dogs, cats and humans throughout Asia, inhabiting the small intestine and possibly leading to iron-deficient anaemia in those infected. It has previously been discovered in domestic dogs in Australia and this is the first report of A. ceylanicum in wild canids. Wild dogs (dingoes and dingo hybrids) killed in council control operations (...

In many bioenergetic investigations, the discrimination of resting and activity metabolism represents an important problem. Personal observation, a possible solution to this problem, becomes very impractical in highly automated long-term experiments. An adequate method of measuring activity should meet the following demands: it should be able to quantify the movement of several objects simultan...

In the genetic system of Cairns and Foster, a nongrowing population of an E. coli lac frameshift mutant appears to specifically accumulate Lac(+) revertants when starved on medium including lactose (adaptive mutation). This behavior has been attributed to stress-induced general mutagenesis in a subpopulation of starved cells (the hypermutable state model). We have suggested that, on the contrar...

The inhibition of DNA replication in aerobically growing Escherichia coli by cyanide or carbon monoxide occurs within about 20 s at 15 degrees, as previously reported by Cairns and Denhardt (Cairns, J., and Denhardt, D.T. (1968) J. Mol. Biol. 36, 335-342). This rapid inhibition can be explained by the nearly complete depletion of both intracellular ATP and deoxynucleoside triphosphates which oc...

Experience with Australian Aboriginal and Torres Strait Islander students in the Bachelor of Applied Health Science (BAppHSc) course suggests that one of the key elements for students is the sense of relationship built up through Problem Based Learning (PBL). Failure to retain students is more likely to be related to personal than academic concerns. The low attrition rate is largely attributed ...

• Ion acoustic solitary waves in the four-component complex plasma with Cairns-Tsallis distribution are studied. Conditions of to exist Numerical analyses for depend on nonextensive and nonthermal parameters made. We study ion consisting cold inertial ions, positrons, hot (two-temperature) electrons, where electrons positrons a have different parameters. Base hydrodynamic equations Sagdeev pseu...
