    Abstract This paper examines the economic and environmental costs of seaweed cultivation (Alaria esculenta) in Ireland and evaluates the potential revenue made on the voluntary carbon offset market (VCOM). The life cycle assessment (LCA) results revealed the cultivation equipment with the polypropylene used for the cultivation lines contributes the highest share of impacts due to their replacement rate. This study suggests long-term employment of farm infrastructure and increased seaweed yield could enhance the environmental sustainability of the system. Moreover, life cycle costing (LCC) indicates the seaweed farm in Ireland is economically feasible over a 20-year lifespan. However, the revenue generated on the VCOM from the seaweed carbon assimilation was minimal, contributing to only 5% of the revenue. This study concludes that further development of the seaweed market with stabilized biomass prices and producing a range of viable products from seaweed biomass will be a major factor in the economic sustainability.

    Abstract The genetics of phosphine resistance was studied in a resistant strain of the red flour beetle, Tribolium castaneum (Herbst), developed from field collections in Queensland, Australia. A program of inbreeding and selection was maintained for 5 generations to promote homozygosity in this strain and a laboratory-susceptible strain. The strain was then 12.7 times resistant in the Food and Agriculture Organization of the United Nations test on adult insects. Data from the testing of F1 progeny from the reciprocal crosses (Rfemale x Smale and Sfemale x Rfemale) indicated that resistance was autosomal and semidominant with a degree of dominance -0.47 (-0.51, -0.44). Modified chi-square analysis and contingency analysis of data from the response of test crosses of F1 progeny to both the susceptible and resistant strains and on F2 progeny were highly significant. Low-level resistance typical of Australian populations of T. castaneum is conferred by > 1 gene.

    Abstract Transgenic fertile soybean plants were generated from somatic embryos of soybean (Glycine max) cv. Jack transformed via particle bombardment with the capsid polyprotein (pCP) gene of Bean pod mottle virus (BPMV). The plant transformation vector (pHIG/BPMV-pCP) utilized in these experiments contained the BPMV-pCP coding sequence, an intron-containing GUS gene, and the hygromycin phosphotransferase gene. Southern blot hybridization analysis showed that 19 transgenic soybean plants selected for resistance to hygromycin contained the genes for GUS and BPMV-pCP. The progeny of five of these transgenic soybean plants (plants 137, 139, 157, 183, and 186) were characterized in detail. An additional transgenic plant (plant 200) contained the intron-GUS and hygromycin resistance genes, but lacked the BPMV-pCP gene and was used as a negative control. Southern blot hybridization analysis of the five transgenic plants showed the presence of three copies of the T-DNA in a similar banding pattern suggesting that they were derived from a single transformation event. Western and northern blot analyses showed that the expression levels of BPMV-pCP and pCP transcript were high in these five pCP plants. Infectivity assays with detached leaves demonstrated that all five pCP plants exhibited resistance to virus infection because they accumulated lower levels of BPMV compared with plant 200 and nontransformed controls. Unlike the T(2) progeny of line 183-1 that segregated with respect to the pCP gene and, consequently, to BPMV resistance, the T(2) progeny of the homozygous line 183-2 showed little or no symptoms in response to rub-inoculation with virions of a severe strain of BPMV. Although BPMV accumulation was evident in leaves on which viruliferous beetles were allowed a 72-h inoculation access period, the upper noninoculated leaves of the T(2) progeny of line 183-2 plants were symptomless and accumulated little or no virus. Because the progeny of this homozygous transgenic line exhibited systemic resistance, they could potentially be useful in generating commercial cultivars resistant to BPMV.

    Abstract The effects of steam pasteurization and hot water immersion treatments on the microbiological profile of whole broiler carcasses and thigh pieces were investigated. Hot water immersion of broiler thigh pieces for 10 s at 80 degrees C and 85 degrees C resulted in significant reductions of 1.09 and 1.25 cfu g(-1) in total viable bacteria (P less than or equal to 0.05). Significant decreases in the numbers of thermophilic Campylobacter were observed on artificially contaminated skin samples following 10 s immersions in water maintained at 75 degrees C, 80 degrees C or 85 degrees C (P less than or equal to 0.05). A 20 s immersion in water at 80 degrees C and 85 degrees C resulted in significant reductions in the recovery of total viable bacteria, Enterobacteriaceae and Campylobacter (P less than or equal to 0.05). Statistically insignificant reductions in the counts of total viable bacteria together with levels of Enterobacteriaceae and thermophilic campylobacters were observed on broiler carcasses exposed to atmospheric steam at 90 degrees C for 12 s when compared to untreated control carcasses. When the exposure time in the steam pasteurization chamber was increased to 24 s, significant reductions in the counts of these organisms were observed with 0.75, 0.69 and 1.3 log10 cfu g(-1) decreases in total viable counts, Enterobacteriaceae and campylobacters, respectively (P less than or equal to 0.05). Visible damage to the outer epidermal skin tissue was observed in both the hot water immersion and steam pasteurization treatments used in the current study.

    Abstract There is high confidence that climate change has increased the probability of concurrent temperature‐precipitation extremes, changed their spatial‐temporal variations and affected the relationships between drivers of such natural hazards. However, the extent of such changes has been less investigated in Australia. Daily data spanning the period 1889‐2019 (131 years) were extracted from SILO gridded dataset at 700 grid cells (1◦ × 1◦) across Australia to calculate annual and seasonal mean daily maximum temperature (MMT) and total precipitation (TPR). A nonparametric multivariate copula framework was adopted to estimate the return period of compound hot‐dry (CHD) events based on an ‘And’ hazard scenario (hotter than a threshold ‘And’ drier than a threshold). CHD extremes were defined as years with joint return periods of longer than 25 years calculated over the period 1889‐2019. Mann‐Kendall nonparametric tests were used to analyse trends in MMT and TPR as well as in the frequency of univariate and CHD extremes. Results showed a general cooling‐wetting trend over 1889‐1989. Significant increasing trends were detected over 1990‐2019 in the frequency and severity of hot extremes across the country while trends in dry extremes were mostly insignificant (and decreasing). A significant increase in the association between temperature and precipitation was identified at various temporal scales. While the frequency of CHD extremes was mostly stable over 1889‐1989, it significantly increased between 1990 and 2019 at 44% of studied grid cells, mostly located in the north, south‐east and southwest.

    Abstract Summary of background data: The SORG-ML algorithms for survival in spinal metastatic disease were developed in patients who underwent surgery and were externally validated for patients managed operatively.
    Objective: To externally validate the SORG-ML algorithms for survival in spinal metastatic disease in patients managed nonoperatively with radiation.
    Study design: Retrospective cohort.
    Methods: The performance of the SORG-ML algorithms was assessed by discrimination [receiver operating curves and area under the receiver operating curve (AUC)], calibration (calibration plots), decision curve analysis, and overall performance (Brier score). The primary outcomes were 90-day and 1-year mortality.
    Results: Overall, 2074 adult patients underwent radiation for spinal metastatic disease and 29% (n=521) and 59% (n=917) had 90-day and 1-year mortality, respectively. On complete case analysis (n=415), the AUC was 0.76 (95% CI: 0.71-0.80) and 0.78 (95% CI: 0.73-0.83) for 90-day and 1-year mortality with fair calibration and positive net benefit confirmed by the decision curve analysis. With multiple imputation (n=2074), the AUC was 0.85 (95% CI: 0.83-0.87) and 0.87 (95% CI: 0.85-0.89) for 90-day and 1-year mortality with fair calibration and positive net benefit confirmed by the decision curve analysis.
    Conclusion: The SORG-ML algorithms for survival in spinal metastatic disease generalize well to patients managed nonoperatively with radiation.
