Nitrogen relations of natural and disturbed plant communities in tropical Australia
Publisher: Springer Science and Business Media LLC
Date: 17-11-1998
Abstract: Nitrogen relations of natural and disturbed tropical plant communities in northern Australia (Kakadu National Park) were studied. Plant and soil N characteristics suggested that differences in N source utilisation occur at community and species level. Leaf and xylem sap N concentrations of plants in different communities were correlated with the availability of inorganic soil N (NH
Effects of Pyrolysis Bio-Oils on Fuel Atomisation-A Review
Publisher: MDPI AG
Date: 03-02-2021
DOI: 10.3390/EN14040794
Abstract: Bio-oils produced by biomass pyrolysis are substantially different from those produced by petroleum-based fuels and biodiesel. However, they could serve as valuable alternatives to fossil fuels to achieve carbon neutral future. The literature review indicates that the current use of bio-oils in gas turbines and compression-ignition (diesel) engines is limited due to problems associated with atomisation and combustion. The review also identifies the progress made in pyrolysis bio-oil spray combustion via standardisation of fuel properties, optimising atomisation and combustion, and understanding long-term reliability of engines. The key strategies that need to be adapted to efficiently atomise and combust bio-oils include, efficient atomisation techniques such as twin fluid atomisation, pressure atomisation and more advanced and novel effervescent atomisation, fuel and air preheating, flame stabilization using swrilers, and filtering the solid content from the pyrolysis oils. Once these strategies are implemented, bio-oils can enhance combustion efficiency and reduce greenhouse gas (GHG) emission. Overall, this study clearly indicates that pyrolysis bio-oils have the ability to substitute fossil fuels, but fuel injection problems need to be tackled in order to insure proper atomisation and combustion of the fuel.

A Systematic Multivariate Analysis of Carica papaya Biodiesel Blends and Their Interactive Effect on Performance

DOI: 10.3390/EN11112931
Abstract: This paper investigates the interactive relationship between three operating parameters (papaya seed oil (PSO) biodiesel blends, engine load, and engine speed) and four responses (brake power, BP torque brake specific fuel consumption, BSFC and, brake thermal efficiency, BTE) for engine testing. A fully instrumented four cylinder four-stroke, naturally aspirated agricultural diesel engine was used for all experiments. Three different blends: B5 (5% PSO biodiesel +95% diesel), B10 (10% PSO biodiesel + 90% diesel), and B20 (20% PSO biodiesel + 80% diesel) were tested. Physicochemical properties of these blends and pure PSO biodiesel were characterised, and the engine’s performance characteristics were analysed. The results of the engine performance experiments showed that, in comparison with diesel, the three PSO biodiesel blends caused a slight reduction in BP, torque, and BTE, and an increase in BSFC. The analysis of variance and quadratic regression modelling showed that both load and speed were the most important parameters that affect engine performance, while PSO biodiesel blends had a significant effect on BSFC.

Quality Estimation of Agave Tequilana Leaf for Bioethanol Production
Publisher: SAGE Publications
Date: 10-2016
DOI: 10.1255/JNIRS.1247
Abstract: Agave tequilana is a potential biofuel crop, for which the characters of juice total soluble sugar content (TSS), dry matter content (DM), cellulose, hemicellulose and lignin content are quality criteria. Spectra of leaves were obtained using a hand-held silicon photodiode array (Si PDA)-based spectrometer with a wavelength range of 300–1100 nm and an InGaAs-based Fourier transform near infrared (FT-NIR) spectrometer with a wavelength range of 1100–2500 nm. Fresh leaves were harvested at different maturity stages, in different seasons and from two locations in Queensland during 2012–2014. Partial least square regression models were developed for DM and TSS of fresh leaf, and for cellulose, hemicellulose and lignin of dried material, with models tested on populations of independent s les collected in different years, seasons and locations. Prediction statistics for DM of fresh leaf using the Si PDA spectrometer (729–975 nm) were r 2 = 0.49–0.87 and root mean square error of prediction ( RMSEP) = 2.36–1.44%, while with the use of the FT-NIR spectrometer, the prediction statistics were r 2 = 0.53–0.66 and RMSEP = 2.63–2.18% (across different years, seasons and locations). Prediction statistics for TSS in fresh leaf using the Si PDA spectrometer (729–975 nm) were r 2 = 0.53–0.69 and RMSEP = 1.70–1.91%, with poorer results obtained using the FT-NIR spectrometer ( r 2 = 0.33–0.56 RMSEP = 1.88–2.45%). With increased s le ersity in the calibration set, NIR technology is recommended for estimation of DM and TSS in fresh Agave leaves. FT-NIR-based prediction of cellulose, hemicellulose or lignin of independent sets (of different years or cultivars) was unsatisfactory, with r 2 0.75 and bias % of mean. These results may be improved with increased s le range, and attention to laboratory (reference method) error. However, leaf cellulose and hemicellulose content may be more easily estimated through correlation to leaf DM level ( R 2 of 0.77 across all s ling events).

Studies on spatial distribution of nickel in leaves and stems of the metal hyperaccumulator Stackhousia tryonii Bailey using nuclear microprobe (micro-PIXE) and EDXS techniques

DOI: 10.1071/FP03192
Abstract: Stackhousia tryonii Bailey is one of the three nickel hyperaccumulators reported from Australia. It is a rare, herbaceous plant that accumulates (Ni) both in leaf and stem tissues. Localisation of Ni in leaf and stem tissues of S. tryonii was studied using two micro-analytical techniques, energy dispersive X-ray spectrometry (EDXS) and micro-proton-induced X-ray emission spectrometry (micro-PIXE). Dimethylglyoxime complexation of Ni was also visualised by bright- and dark-field microscopy, but this technique was considered to create artefacts in the distribution of Ni. Energy dispersive X-ray spectrometric analysis indicated that guard cells possessed a lower Ni concentration than epidermal cells, and that epidermal cells and vascular tissue contained higher levels of Ni than mesophyll, as reported for other Ni hyperaccumulators. The highest Ni concentration was recorded (PIXE quantitative point analysis) in the epidermal cells and vascular tissue (5400 μg g–1 DW), approximately double that recorded in palisade cells (2500 μg g–1 DW). However, concentrations were variable within these tissues, explaining, in part, the similarity between average Ni concentrations of these tissues (as estimated by region selection mode). Stem tissues showed a similar distribution pattern as leaves, with relatively low Ni concentration in the pith (central) region. The majority of Ni (73–85% for leaves 80–92% for stem) was extracted from freeze-dried sections by water extraction, suggesting that this metal is present in a highly soluble and mobile form in the leaf and stem tissues of S. tryonii.

Associations of Daily Pedometer Steps and Self-Reported Physical Activity With Health-Related Quality of Life
Publisher: SAGE Publications
Date: 20-10-2015
Abstract: Objective: The aim of this article is to examine associations of self-reported physical activity (PA) and pedometer steps with health-related quality of life (HRQoL) among a population-based s le of older adults. Method: Adults ≥55 years ( N = 1,296) were recruited through random-digit dialing and responded to a questionnaire via computer-assisted telephone interviewing methods. Questionnaires assessed demographic variables and validated measures of PA and HRQoL. Participants received a step pedometer and waist circumference tape measure via post. Results: Compared with participants in the low-step group (0-6,999 steps/day), participants in the high-step group ( ,000 steps/day) had significantly higher scores on mental health ( M diff = 3.1, p .001, confidence intervals [CI] = [1.8, 4.3]), physical health ( M diff = 3.5, p .001, CI = [2.2, 4.7]), and global health ( M diff = 3.5, p .001, CI = [2.3, 4.7]). Waist circumference and body mass index did not moderate any associations of pedometer steps and PA with HRQoL. Conclusion: Older adults exceeding established step thresholds reported significantly higher HRQoL indices compared with those achieving lower thresholds.

Pasture composition in cleared and uncleared woodlands
Publisher: CSIRO Publishing
Date: 2006
DOI: 10.1071/BT05174
Abstract: Land clearing in Queensland is often practised to enhance pasture production, and hence, increase financial returns from beef production. The benefits of clearing have been quantified in terms of short-term gains in pasture yield but have not adequately accounted for possible medium- or longer-term impediments that may be attributed to clearing. Therefore, impacts of clearing and the subsequent sowing of exotic grasses such as Cenchrus ciliaris L. on pasture composition and production were studied. To achieve this, paired sites were selected representing cleared and uncleared pastures across three different times since clearing (i.e. 5, 11–13 and 33 years since clearing) for the three dominant tree communities of central Queensland (i.e. Eucalyptus populnea F.Muell. (poplar box), E. melanophloia F.Muell. (silver-leaved ironbark) and Acacia harpophylla F.Muell. ex. Benth. (brigalow)). The results demonstrated that species ersity declined with clearing and sowing of exotic pastures. Species ersity and pasture production were negatively related. Although pasture yield was 2–3 times greater 13 years after clearing of E. populnea and A. harpohylla, the gains in pasture yield were not consistent over time, yields being only 1.5 times greater after 33 years of clearing. In E. melanophloia, an increase in the yield of only 1.5–1.8 times occurred 5 years after clearing compared with uncleared pastures, whereas 33 years after clearing, yield was 3/4 of that in uncleared pastures. The initial gains in pasture yield were accompanied by a loss of plant ersity that may affect ecosystem functions such as nutrient cycling or soil mineralisation, and the longer-term production gains.
Maximizing energy recovery from beauty leaf tree (Calophyllum inophyllum l.) oil seed press cake via pyrolysis
Publisher: MDPI AG
Date: 03-05-2021
DOI: 10.3390/EN14092625
Abstract: This study optimizes pyrolysis conditions that will maximize energy recovery from the Beauty Leaf Tree (BLT Calophyllum inophyllum L.) oil seed press cake. Response surface methodology (RSM) was used to determine the behavior of pyrolysis coproducts (solid, liquid and gas) at various temperatures and residence times. One significant discovery was that 61.7% of the energy (of the whole BLT oil seed) was still retained in the BLT oil seed cake after oil extraction. Controlled pyrolysis produced various proportions of biochar, bio-oil and syngas coproducts. Predictive models were developed to estimate both the mass and energy yields of the coproducts. In all experimental runs, the biochar component had the highest mass yield and energy content. Biochar mass yields were high at the lowest operating temperature used, but the energy yields based on a high heating value (HHV) of products were optimal at higher operating temperatures. From the RSM models, energy from the biochar is optimized at a pyrolysis temperature of 425 °C and 75 min of exposure time. This biochar would have a heating value of 29.5 MJ kg−1, which is similar to a good quality coal. At this condition, 56.6% of the energy can be recovered in the form of biochar and 20.6% from the bio-oil. The study shows that almost all the energy present in the feedstock can be recovered via pyrolysis. This indicates that commercial biodiesel producers from BLT oil seed (and other oil seed) should recover these additional valuable energies to generate high value coproducts. This additional efficient energy conversion process via controlled pyrolysis will improve the overall economics and the feasibility of 2nd generation biodiesel production from BLT—a highly potential species for cultivation in many tropical countries.

Investigation on the impact of papaya biodiesel-diesel blends on combustion of an agricultural CI engine

DOI: 10.1088/1755-1315/463/1/012001
Abstract: In this study, an overview of combustion characteristics of an agricultural diesel engine fuelled with papaya seed oil (PSO) biodiesel and diesel is presented. A naturally aspirated four-cylinder four-stroke tractor engine was used for all experiments. Various PSO blends (5%, 10%, and 20%) were tested and compared with diesel at speeds of 1400 rpm and 2400 rpm at full load condition. The combustion characteristics such as in-cylinder pressure, heat release rate, ignition delay, mass fraction burned, ignition duration and cylinder temperature were tested. The results show that PSO blends have some excellent attributes as fuel in regard to combustion characteristics. All PSO biodiesel blends have higher in-cylinder pressure for ex le, PSO20 has 2.4% more than diesel. Heat release rate values of all PSO biodiesel blends were found to be lower than diesel due to the shorter ignition delay and lower calorific values of biodiesel. PSO20 biodiesel shows faster combustion than diesel by about 11.92% at 1400 rpm and 7.93% at 2400 rpm. The maximum cylinder temperature of all PSO biodiesel blends are also higher than that of diesel, such as PSO20 at 1400 rpm by 3.17% and at 2400 rpm by 3.73%.

Enteric bacteria build-up in effluent irrigated plantations
Publisher: CSIRO Publishing
Date: 2009
DOI: 10.1071/MA09040
Abstract: Australia uses more than 70% of re-used effluent as irrigation in playgrounds, parks, golf courses and race courses. This land irrigation is preferred over other methods (wetlands, tertiary treatment and aquifer storage) for being the economical, practical and vastly applicable option. Bacteria (Escherichia coli, and Salmonella spp.), protozoa (Giardia spp. and Cryptosporidium spp.), viruses (Poliovirus, Coxsackie virus and Norwalk virus) and helminths (tapeworms and hookworms) are the major pathogens present in municipal effluent. These enteric pathogens have the potential to enter the food chain and cause health risks. Although enteric pathogens start dying once in contact with aerobic environment, bacterial build-up as well as decay rate should be probed periodically.

DOI: 10.1071/BT01035
Abstract: Stackhousia tryonii Bailey is a rare, serpentine-endemic herb, with potential for use in phytoremediation and/or phytomining. This study evaluates the use of herbaceous heel cuttings to propagate S. tryonii on three rooting media [sand, Medium I a commercial nursery mix, Medium II and sand : peat moss : perlite (2 : 2 : 1 v/v), Medium III] following the application of plant growth hormones, viz. indole-3-butyric acid and naphthalene acetic acid (both as pure and commercial formulations, viz. Clonex Gel-green, Gel-purple and Gel-red), and honey. Cutting survival, rooting percentage, the number of primary and secondary roots produced, the length of the longest root and the total root length were evaluated after 10 weeks. Results show that there was a positive (P 0.001) influence of plant growth regulator treatments on cuttings' survival. Medium III failed to support survival of cuttings. Percentage rooting (as a proportion of original number of cuttings) was 10–30% higher in Medium I than in Medium II. Cuttings treated with Clonex Gel-red, IBA at 1000 ppm and NAA at 250 ppm had 60–70% higher percentage rooting in Medium�I than in Medium II. Total number of primary roots per rooted cuttings was significantly (P� �0.05) higher in Medium I with Clonex Gel-red and NAA at 1000 ppm. Treatments did not have significant effects on the number of secondary roots, the length of the longest root and the total root length. However, values for these parameters were significantly (P 0.05) higher in Medium I than in Medium II. We conclude that cuttings from mature plants of S. tryonii could be used effectively to multiply S. tryonii, particularly with sand as rooting medium and prior to treatment of cuttings with Clonex Gel-red.

Field performance of a phytocap at Lakes Creek landfill, Rockhampton, Australia
Publisher: Emerald
Date: 02-03-2010
DOI: 10.1108/14777831011025571
Abstract: Landfill capping is a mandatory post closure procedure in Australia to isolate the deposited wastes from the outside environment, mainly water. Compacted clay caps are predominantly used in Australian landfills. Recent studies have shown that clay caps have shorter life span and fail to prevent percolation of water due to cracking. This paper aims to discuss a new technology called “Phytocapping” that has been trialled at Lakes Creek landfill in Rockh ton. In this technique, trees were used as “bio‐pumps” and “rainfall interceptors” and soil cover as “storage” of water. The field performance of the phytocapping system was measured based on its ability to minimise water percolation into waste. Tree growth, transpiration, canopy rainfall interception and methane emission were monitored over three years. The percolation rate was modelled using HYDRUS 1D code for two different scenarios (with and without vegetation) for the thick (1,400 mm soil) and thin (700 mm soil) phytocaps respectively. Results from the modelling showed percolation rates of 16.7 mm yr −1 in thick phytocap and 23.8 mm yr −1 in thin phytocap, both of which are markedly lower than those expected from a clay cap. Results from monitoring and observations showed that 19 of 21 tree species grew well in the harsh landfill environment. However, the correct species selection is very important for the long‐term sustainability of the phytocap. Results also show that phytocaps can reduce a significant amount of methane emission from landfills. The cost of landfill capping is escalating and is putting a lot of financial and legal pressure on the small and medium sized local governments in Australia. The phytocapping technique not only offers financial benefits but also has some environmental and commercial benefits. The paper focuses on a new technology being used in waste management.

Abstract: In this study, the production process of second-generation biodiesel from Australian native stone fruit have been optimised using response surface methodology via an alkali catalysed transesterification process. This process optimisation was performed varying three factors, each at three different levels. Methanol: oil molar ratio, catalyst concentration (wt %) and reaction temperature were the input factors in the optimisation process, while biodiesel yield was the key model output. Both 3D surface plots and 2D contour plots were developed using MINITAB 18 to predict optimum biodiesel yield. Gas chromatography (GC) and Fourier transform infrared (FTIR) analysis of the resulting biodiesel was also done for biodiesel characterisation. To predict biodiesel yield a quadratic model was created and it showed an R2 of 0.98 indicating the satisfactory performance of the model. Maximum biodiesel yield of 95.8% was obtained at a methanol: oil molar ratio of 6:1, KOH catalyst concentration of 0.5 wt % and a reaction temperature of 55 °C. At these reaction conditions, the predicted biodiesel yield was 95.9%. These results demonstrate reliable prediction of the transesterification process by Response surface methodology (RSM). The results also show that the properties of the synthesised Australian native stone fruit biodiesel satisfactorily meet the ASTM D6751 and EN14214 standards. In addition, the fuel properties of Australian native stone fruit biodiesel were found to be similar to those of conventional diesel fuel. Thus, it can be said that Australian native stone fruit seed oil could be used as a potential second-generation biodiesel source as well as an alternative fuel in diesel engines.
