    Notes: There is expanding interest in the culture of the Australian shortfin eel Anguilla australis Richardson; however, there is a lack of fundamental biology and husbandry information necessary to further develop an industry within Australia. The present study was undertaken to gain a preliminary understanding of basic husbandry requirements for rearing of juvenile A. australis (glass eels and elvers) in tanks and earthen ponds. Newly caught glass eels were successfully acclimated to culture conditions. During tank culture trials, specific growth rates (SGR) and survival rates ranged from −2.1 to 2.8% day−1 and 52% to 100% respectively. Glass eels weaned onto a commercial eel diet exhibited a significantly greater SGR and survival rate than those weaned onto a commercial trout diet. Glass eels weaned onto an eel diet over a 15-day period grew slightly faster than eels weaned over a 5-day period, but survival rates were not significantly different for each treatment. SGRs (up to 2.8% day−1) were significantly higher for glass eels fed at 9 and 12% day−1 than at 6% day−1. Stocking densities between 2.5 kg m−3 and 30 kg m−3 did not influence either SGR or survival rates. SGRs were significantly higher for glass eels cultured at 25 °C than at lower temperatures. During pond culture trials, SGRs and survival rates ranged from 1.36 to 1.65% day−1 and 39% to 77% respectively. The SGR and survival rates of juvenile eels stocked into ponds receiving supplementary feeding with a commercial eel diet were not significantly different to those of eels stocked into ponds that did not receive supplementary feeding.

    Notes: Murray cod Maccullochella peelii peelii (Mitchell) is a freshwater Percichthyid fish considered to have high culture potential. Growth and feed utilization were examined in a 56-day experiment, in which triplicate groups of juvenile Murray cod (initial weight 21.5 ± 0.03 g) were fed isocalorific diets (gross energy content of about 21 kJ g−1) containing 40%, 45%, 50%, 55% or 60% protein (designated P40, P45, etc.). Final mean weight, percentage increase in weight and specific growth rate (SGR; % day−1) were highest in fish fed the P50 diet. Food conversion ratio (FCR; 1.05 ± 0.04) and protein efficiency ratio (PER; 1.98 ± 0.11) were also best in fish on the P50 diet, but the differences in these parameters from the corresponding values on diets P55 and P60 were not always significant. FCR (Y) was related to dietary protein content (X), the relationship being a second-order polynomial, in which Y = 0.004X2−0.431X + 12.305 (r= 0.95; P 〈 0.01). The proportions of carcass moisture, protein, lipid and ash did not differ among the different dietary treatments. The protein conversion efficiency (y) was negatively correlated to percentage dietary protein (X) content, the relationship being: y = 62.76–0.62X (r= 0.99; P 〈 0.01).

    Radiation damage and annealing studies of ion bombarded cobalt (1984)

    Notes: Abstract The effects of implantation-induced radiation damage on the thermal oxidation of cobalt have been studied. Bombardment by both Co+ self-ions and by Xe+ has been studied as a function of ion dose, energy and annealing temperature. A major increase in oxidation was observed for doses of 〉1016 Co+ cm−2 in agreement with previous studies on Al. The oxidation behaviour as a function of annealing temperature was markedly different for Co+ and Xe+ bombarded samples. For Co+ bombarded samples, damage anneals rapidly in the temperature range 20–300°C due to thermally assisted repair of point defects and vacancy clusters. However, for Xe+ bombardment, it is proposed that the higher annealing temperatures required for damage repair arise due to the stabilisation of three-dimensional vacancy clusters by the oversized Xe atoms. The increase in oxidation after annealing in the temperature range 300–500°C is thought to be due to vacancy release mechanisms which may affect oxide nucleation.

    Notes: Abstract Ion beam induced mixing of Al-Ni has been studied using N 2 + and Ar+ bombardment. High dose (4×1017 ions cm−2) nitrogen bombardment was found to cause blister formation with no unambiguous evidence of mixing. However, using argon ions at elevated substrate temperatures (400–450 °C) led to extensive mixing of 2000 Å Al layers on Ni. The mixing mechanism is considered to be point defect mediated radiation enhanced diffusion with a possible contribution from cascade mixing and interfacial oxide layer breakdown during the initial stages of treatment.

    Notes: Abstract Ion bombardment induced mixing of Ta-Si films has been studied using 400 keV argon ions. Doses varied from 7×1014 to 1×1017 Ar+ cm−2 with post-bombardment anneals of 180–900 s at temperatures in the range 600–860 °C using radiant heating. Silicide uniformity and stoichiometry were determined using alpha backscattering spectrometry. Optimum fabrication parameters were determined with regard to subsequent material sheet resistivity, temperature coefficient of resistance and application as a temperature sensing material. Similar measurements were made on CoSi2 layers prepared by annealing ion bombarded samples and comparison with silicide films arising from purely thermal annealing was made. CoSi2 was found to be the more suitable material for temperature-sensor applications, showing a positive linear variation in sheet resistivity in the range 0–400 °C for samples which could be prepared simply and reproducibly.

    Notes: Abstract Studies have been made of the application of certain phthalocyanine films in the detection of toxic gases such as chlorine. Consideration has been given to preparation parameters such as deposition conditions (evaporation rate, ambient pressure, post deposition annealing) together with varying central metal atoms within the phthalocyanine molecule. Particular studies have been made concerning the relationship between elevated substrate temperature deposition, the molecular structure and the corresponding sensitivity of the films to gases. The present results are considered within the context of the development of an economically viable selective thin film gas sensor.
