    Notes: Abstract. There is environmental concern about the increasing land application of dairy shed effluent in New Zealand. To minimize groundwater contamination by applied nutrients and pathogens it is desirable to avoid preferential flow through topsoils. Our objective was to determine an irrigation rate that retained applied effluent in the topsoil of two commonly irrigated New Zealand soils. In a field experiment, well drained Horotiu soils and poorly drained Te Kowhai soils were irrigated with a pyranine dye/KBr tracer solution at four rates (5, 10, 15, 20 mm/h) using a drip-type rainfall simulator. Twenty minutes after irrigation ceased the soil was excavated horizontally at 25 or 50 mm intervals, and photographed under UV light until no further fluorescence was vishle. Each layer was also analysed for bromide content, without subsampling. The wetting pattern was uneven in both soils as leachate moved preferentially through worm channels and structural cracks. Preferential flow was greatest in the Te Kowhai soil and increased at faster application rates. Dye fluorescence was curvilinearly related to bromide concentration. At both study sites, maintaining the irrigation rate at 〈inlineGraphic alt="leqslant R: less-than-or-eq, slant" extraInfo="nonStandardEntity" href="urn:x-wiley:02660032:SUM96:les" location="les.gif"/〉 10 mm/h minimized leachate movement into the subsoil. Pulsed irrigation at faster rates was not retained in the topsoil.

    Notes: The deposition of silver on a C60 monolayer chemisorbed on Si(111) leads to the formation of nanoscale clusters which, as determined from valence band photoemission measurements, donate minimal charge to the adsorbed fullerene molecules. The low doping level of the C60 monolayer leads to a slow rate of Ag cluster neutralization following the emission of a photoelectron, resulting in a significant shift of the cluster Fermi level and valence band features to higher binding energy. © 2000 American Institute of Physics.

    Responsible estuarine finfish stock enhancement: an Australian perspective (2005)

    Notes: The responsible approach to marine stock enhancement is a set of principles aimed at maximising the success and benefits of artificially re-stocking depleted fisheries. The benefits of such an approach are evident in the 400% increase in survival of stocked striped mullet in Hawaii through refinement of release techniques, however financially or temporally constrained stocking programs in Australia have not adhered to all principles. A pragmatic approach to address these principles is proposed, using international examples and Australian marine finfish pilot stockings of barramundi, mulloway, sand whiting, dusky flathead and black bream. Biological ranking of candidate species by estuarine residency, a low natural-mortality to growth ratio, a large L∞ and comparison by recreational value and available rearing technologies, show that mulloway, barramundi and sea mullet are ideal species for stocking in Australia. Australian intermittently closed opening landlocked lagoons and recreational fishing havens, especially near cities, provide experimental opportunities to apply this approach and stock suitable species through small-scale pilot experiments. This would allow evaluation of production and carrying capacity, and density dependent processes with respect to optimal stocking strategies unconfounded by emigration and commercial fishing practices. Twenty per cent of Australians fish each year, and harvest approximately 27 000 t of finfish. Stocking recreationally important species in Australia should give a greater financial benefit, which is spread across a larger cross-section of the community, compared to stocking to enhance commercial fisheries. The pragmatic application of the responsible approach, and stocking of fast growing estuarine residents into recreational fishing havens would enhance the benefit from marine stocking.

    Notes: Juvenile mulloway Argyrosomus japonicus(54·6 ± 4·6 mm total length, mean ± s.e.) were immersed in a range of oxytetracycline (OTC) solutions ranging between 0–600 mg l−1 in salinities of 5 (diluted sea water) and 35 (undiluted sea water), and alizarin complexone (ALC) solutions ranging between 0–60 mg l−1 in undiluted sea water, for 6, 12 and 24 h. Optimal marking conditions were 600 mg l−1 OTC for 24 h in a salinity of 5, and 30 mg l−1 ALC for 12 h respectively. Mark quality (MQ) was assessed using a score of 0–3 in both otoliths and anal fin spines, with a score 〉2 found to be acceptable for adequate mark identification. Acceptable marks were not produced using OTC in undiluted sea water. Immersion in OTC or ALC, or reduced salinity had no effect on survival relative to controls. Transverse sections of vertebrae from the ALC and OTC treatments with the highest otolith mark quality showed no discrete marks. Optimal marking techniques were used to produce double marks with a 3 day interval between marking, and marking techniques were applied to 130 000 juvenile mulloway in batch mode with minimal mortality. A numerical model of the chemical behaviour of OTC in sea water describes the decline of available OTC in increasing salinity, so that a species’ salinity tolerance and successful marking can be optimized.

    Notes: Aims: To compare the efficacy, safety and tolerability of an omeprazole/amoxycillin (OA) dual therapy Helicobacter pylori eradication regimen with an omeprazole/amoxycillin/metronidazole (OAM) triple therapy regimen. Methods: In this double-blind trial, conducted in 19 hospitals, 119 patients with symptomatic duodenal ulcer disease were randomized to receive either 14 days treatment with omeprazole 40 mg daily, amoxycillin 500 mg t.d.s. and placebo followed by a further 14 days’treatment with omeprazole 20 mg daily (n= 59) or 14 days treatment with omeprazole 40 mg daily, amoxycillin 500 mg t.d.s., and metronidazole 400 mg t.d.s., followed by a further 14 days’treatment with omeprazole 20 mg daily (n= 60). H. pylori status was assessed by 13C-urea breath test at entry and at 4 weeks post-treatment. Results: H. pylori infection was eradicated in 46% of the OA treated patients and in 92% of the OAM treated patients, a mean difference of 46% (P 〈 0.0001, 95% CI for the difference: + 30 to + 62). In only one patient was the duodenal ulcer not endoscopically healed after 4 weeks of treatment (OA 100%; OAM 98% healed). There were no significant differences in speed of symptom relief or improvement in symptoms between the two groups. Both regimens were well tolerated, with 96% of patients completing the course, and only one patient withdrawing due to an adverse event. The only side-effect with a significantly higher incidence in the OAM group was diarrhoea, which occurred in 36% of patients compared to 16% of patients in the OA group (P 〈 0.05). Conclusions: A regimen consisting of omeprazole 40 mg daily, amoxycillin 500 mg t.d.s. and metronidazole 400 mg t.d.s. for 14 days gives an appreciably higher H. pylori eradication rate than omeprazole and amoxycillin alone, with acceptable tolerability.

    Notes: Aim: To determine the effect of Helicobacter pylori eradication with omeprazole and amoxycillin, with or without metronidazole, on the 12-month course of duodenal ulcer disease. Methods: In a randomized, double-blind study, conducted in 19 hospitals, 105 H. pylori positive duodenal ulcer patients were healed and symptom-free following either omeprazole dual therapy (omeprazole 40 mg o.m.+amoxycillin 500 mg t.d.s., OA, eradication rate 46%, n=52) or omeprazole triple therapy (omeprazole 40 mg o.m.+amoxycillin 500 mg t.d.s.+metronidazole 400 mg t.d.s., OAM, eradication rate 92%, n=53) for 2 weeks, followed by 2 weeks of omeprazole 20 mg o.m. and a 12-month untreated follow-up period, after which time all patients were endoscoped. Endoscopic and symptomatic relapse rates, and effect on H. pylori status measured using 13C-urea breath test, were determined. Results: During the 12-month untreated follow-up period, the life-table endoscopic relapse rates were 12% (95% CI: 2–22%) and 2% (95% CI: 0–6%) for OA and OAM patients, respectively. By 12 months, life-table symptomatic relapse rates were 22% (95% CI: 13–37%) and 19% (95% CI: 8–30%) for OA and OAM, respectively. In the 12 months untreated follow-up period, 2/69 (3%, 95% CI: 0–7%) patients rendered H. pylori negative had an endoscopic relapse at the end of the 12-month follow-up period, compared with 5/31 (16%, 95% CI: 3–29%) patients remaining H. pylori positive (P=0.03 between H. pylori positive and negative groups). Twelve of 69 (17%, 95% CI: 8–26%) patients rendered H. pylori negative relapsed symptomatically, compared with 9/31 (29%, 95% CI: 13–45%) patients remaining H. pylori positive (P= N.S. between groups). There was a significant improvement in epigastric pain (P=0.0001), nausea and vomiting (P〈0.05) between entry to the study and 1, 6 and 12 months post-treatment for both treatment groups. Conclusions: OAM eradicates H. pylori in significantly more patients than OA, but successful H. pylori eradication with either OAM or OA predisposes to low endoscopic and symptomatic relapse rates for duodenal ulcer patients when followed up for 12 months.
