description: Ethanol extract (EE) and fractions obtained from the ripe fruits of Solanum lycocarpum were examined in order to determine their phenolic composition, antioxidant capacity, antibacterial activities and cytotoxic potential. High-performance liquid chromatography coupled with DAD analysis indicated that caffeic and chlorogenic acids were the main phenolic compounds present in the EE, dichloromethane (DCM) and ethyl acetate (Ac) fractions. The antioxidant activity assessed by the scavenging ability on 1,1-diphenyl-2-picrylhydrazyl radical was significantly more pronounced for DCM and Ac fractions than that of the commercial antioxidant 2,6-di-tert-butyl-4-methylphenol (BHT). EE and fractions exhibited selective antibacterial activity against Gram-positive bacteria, especially the hexane (Hex) and DCM fractions. EE and fractions exhibited low toxicity towards the LLC-MK2 cell line, especially the Hex, DCM and Ac fractions. This work provides the knowledge of phenolic composition in the extract and fractions from the ripe fruits of S. lycocarpum and their antioxidant, antibacterial and cytotoxic activities.

Three dimensional gully mapping and erosion quantification within a geoinformatics framework
Creators: name: Sattar, Farha
Publisher: name: Charles Darwin University

description: The contribution of gully erosion to total soil loss has been much debated amongst geomorphologists and hydrologists. However, there is growing evidence that gullies are a major contributing source of sediment in river systems. The study area for this thesis, the Fergusson River catchment; a sub-catchment of the Daly River, Northern Australia, is no exception. This thesis presents and uses a Geoinformatics based framework for three dimensional (3D) gully mapping that focuses on the spatio-temporal analysis and quantification of gully erosion. The framework incorporates traditional and cutting edge spatial data and technology, namely Cartosat-1 stereo imagery, topographic maps, a 1_second Shuttle Radar Topographic Mission, Digital Elevation Model, historical stereo aerial photos, and Differential Global Positioning System measurements and thematic layers representing the physical and human environment. The framework is used to create Digital Surface Models (DSM) from the 2008 Cartosat-1 stereo imagery and 1948 stereo aerial photographs. Gullies are identified based on 3D visualization of these images and their 3D properties mapped from the DSMs. Four classes of gullies were identified in the study area based upon their spatial distribution in the catchment, morphology and inferred underlying erosion processes; amphitheatre gullies, gullied slumps, bank gullies and ‘other gullies’. Sapping is the primary erosion process for gullying. Volumetric changes in gully erosion between 2008 and 1948 have been measured and the specific yield of gully erosion is determined to be 6.1x103 t km-2 yr-1. A regional and global comparison of the estimated specific sediment yield indicates that it is globally among the highest. Gully control factors are examined and causes of gully initiation and development have been described. The results show that alluvial soils are most prone to gullying but heterogeneity in gully distribution and form indicates that other factors are likely to affect gully formation and development in the catchment.

description: To overcome the precision limitation and environmental impact of current chemical-based production methods for manufacturing silk microfibres used for targeted drug delivery, this paper presents a high-precision, scalable, eco-friendly mechanical machining approach to produce such microfibres in the form of discontinuous chips obtained through elliptical vibration turning of silk fibroin film using a diamond tool. The length and waist width of fabricated microfibres can be precisely controlled. As each vibration cycle will produce one silk microfibre, complete and deterministic chip breakage becomes an essential and challenging task in this approach due to its unique two-phase structure. Thus, the hybrid FE-SPH numerical simulations and machining experiments were conducted to gain a pioneering and in-depth exploration of the chip-breaking mechanism in this process. It was found that applying a low depth ratio (ratio of the nominal depth of cut to the tool path vertical amplitude) and a high horizontal speed ratio (the nominal cutting speed versus the critical workpiece velocity) could effectively reduce the average tool velocity angle (the angle from the deepest cut to the tool exit point along the cutting direction). A smaller angle would enhance the diamond tool's shearing action and led to the reduction of hydrostatic pressure in the cutting zone and a consequent decrease in the ductility of silk fibroin due to its unique structure dominated by beta-sheet crystallites. The above adjustments collectively facilitated chip breakage. This paper, therefore, established a governing rule for the controlled and repeatable formation of microfibres based on the average tool velocity angle for the first time and revealed that the cutting chips would undergo complete and deterministic breakages once the angle approached below 22.6°. On this basis, the high-precision and scalable manufacturing of silk microfibres with precisely controllable length and waist width was ultimately achieved.

description: Abstract
In today's world, almost any armed conflict involving national military forces or non-state actors,
results in allegations of war crimes and calls for investigations and prosecutions. As continued
penetration of the Internet in the society leads to ever more thorough scrutiny of military operations,
the world's military forces are in a continuous struggle for situational awareness via their own networkcentric Battlefield Management Systems(BMS). But in many publications on the subject matter, little attention is paid as pertains to improving the humanitarian conditions in the Battle-space. The focus for the moment seems to be geared towards the attainment of tactical military objectives, by conducting military operations against, seemingly virtual adversaries. Pragmatically speaking 'claiming that a war can be conducted without atrocities, is akin to claiming that a market can be free from fraud'.

description: The Transitional Federal Government of Somalia, backed by the United Nations and protected by AMISOM ( African Union Mission in Somalia) peace
keepers, is the main impediment to Al Shabaab’s insurgency objective of taking full control of Somalia. Given the military superiority demonstrated by way of AMISOM bases, armored vehicles and personnel in Mogadishu, Somalia, anti-TFG insurgent forces, have
adopted local terror operations to placate the population of Somalia and international terror operations to induce the withdrawal of AMISOM armed intervention from Somalia. Though fractious and with ill-defined leadership structures, a critical mass of anti-TFG insurgents are merged under the banner of Al Shabaab. This paper analyses
the behavior and intentions of key operators in Al Shabaab, with a view to deducing the underlying doctrine behind its covert operations and global
ambitions.

description: Many conflicts in the world today are dominated by leaders who are terrorist fugitives or suspected war criminals whose capture is necessary for peace to
prevail, while even in societies that may claim to enjoy relative peace and tranquility, criminality may range from general nuisance level to the extremes of
organized crime gangs that capture the legislative, judicial and executive mechanisms of State, resulting in local and / or transnational crimes that compel governments to seek for warrants of arrest targeting a wanted person. In some instances a fugitive may not only be a person in flight from the consequences of criminal culpability, for in today’s world of high risk enterprise there are increasing
instances of fugitives in flight to escape from the consequences of civil liability.

description: Landslides are socio-natural hazards. In Colombia, for example, these are the most frequent hazards. The interplay of climate change and the mostly informal growth of cities in landslide-prone areas increases the associated risks. Landslide early warning systems (LEWSs) are essential for disaster risk reduction, but the monitoring component is often based on expensive sensor systems. This study presents a data-driven approach to localize landslide-prone areas suitable for low-cost and easy-to-use LEWS instrumentation, as well as to estimate the associated costs. The approach is exemplified in the landslide-prone city of Medellín, Colombia. A workflow that enables decision-makers to balance financial costs and the potential to protect exposed populations is introduced. To achieve this, city-level landslide susceptibility is mapped using data on hazard levels, landslide inventories, geological and topographic factors, and a random forest model. Then, the landslide susceptibility map is combined with a population density map to identify highly exposed areas. Subsequently, a cost function is defined to estimate the cost of LEWS monitoring sensors at the selected sites, using lessons learned from a pilot LEWS in Bello Oriente, a neighbourhood in Medellín. This study estimates that LEWS monitoring sensors could be installed in several landslide-prone areas with a budget ranging from EUR5 to EUR41 per person (roughly COP23000 to 209000), improving the resilience of over 190000 exposed individuals, 81% of whom are located in precarious neighbourhoods; thus, the systems would particularly reduce the risks of a social group of very high vulnerability. The synopsis of all information allows us to provide recommendations for stakeholders on where to proceed with LEWS instrumentation. These are based on five different cost-effectiveness scenarios. This approach enables decision-makers to prioritize LEWS deployment to protect exposed populations while balancing the financial costs, particularly for those in precarious neighbourhoods. Finally, the limitations, challenges, and opportunities for the successful implementation of a LEWS are discussed.

description: The synthesis of a library of halogenated rocaglate derivatives belonging to the flavagline class of natural products, of which silvestrol is the most prominent example, is reported. Their antiviral activity and cytotoxicity profile against a wide range of pathogenic viruses, including hepatitis E, Chikungunya, Rift Valley Fever virus and SARS-CoV-2, were determined. The incorporation of halogen substituents at positions 4′, 6 and 8 was shown to have a significant effect on the antiviral activity of rocaglates, some of which even showed enhanced activity compared to CR-31-B and silvestrol.
Oxygen transport in varanid lizards during exercise
Creators: name: Schultz, Timothy
Publisher: name: Charles Darwin University
Year: 2002

description: I measured maximal oxygen consumption (Vo 2max) and standard metabolic rate in ten species of goannas to test whether, as a group, goannas have higher metabolic rates than other lizards. I found significant variation within this group of goannas, and no difference between goannas and other lizards in either measures of metabolic rate. Metabolism within the goannas was also examined with respect to foraging mode and habitat preference. Interspecific comparison of goanna metabolism adds support to the aerobic capacity hypothesis for the evolution of endothermy, and factorial scopes in lizards (≥10) are at least the equivalent of mammalian values. Ventilation rate was measured concurrently with oxygen consumption in the experiments outlined above. During exercise, the increase in oxygen consumption rate was matched by a similar increase in ventilation rate, such that the ratio between ventilation and metabolism remained constant. This is significant given previous reports of hypoventilation (due to a mechanical constraint) and hyperventilation (in response to either an impairment to gas exchange or increased shunting). There is some evidence supporting the use of gular pumping in these goannas, and strong evidence for mouth breathing during exercise, which prohibits the sampling of nasal expiration only. The present study is the first to measure pulmonary diffusing capacity (DLco ) during exercise in a reptile. I found that DLco doubled on average due to exercise, however, from five species (four varanids, one agamid) four different responses to exercise were apparent. These differences are most likely related to different behavioural responses to "resting" states, as well as differences in lung anatomy. I examined the haematological and rheological response to exercise in a range of lizard species. Differences in aerobic ability of these species were not related to either haematology or rheology, with the exception of mean erythrocyte volume. The applications and methods of optimal haematocrit theory are considered.

description: This dissertation addresses the problem of manhunts, against criminal fugitives. It establishes
new ways of describing and refining mechanisms and techniques, for manhunts. Methods used in this
dissertation to meet those objectives, include: review of case studies, benchmarking of techniques and
the analysis of techniques and concepts, which have been put forward by other scholars. Emphasis
has been placed on the applicability of search techniques to a wide range of situations, and techniques for shielding the actual intentions of a search-interdiction party, from the fugitive’s support network. Also derived from the analyses and case studies in this dissertation, are some innovative concepts that enhance the manhunt tradecrafts of personnel currently engaged in on-going searches for fugitives and insights into fugitive psychology. Though the case studies have got a wide range of characteristics idiosyncratic to their subjects, illustrations of similarities and correspondence in otherwise, obviously unrelated case studies, is empirical evidence of the importance of review of past cases, to assist in the refining of future manhunt operations. The dissertation, proposes various manhunt tradecraft solutions, which may be widely applicable, even in situations where search-interdiction teams have very limited operations funding, but can nevertheless assist in obtaining success by a resourceful operative. The dissertation further seeks to give any new search-interdiction operative initial procedures and points of inquiry, while for the skilful operatives, it provides various methods for refinement of techniques and performance benchmarking.

description: As network access costs, especially over the last mile, decrease and broadband access becomes more available to the home user, the idea of video-on-demand (VoD) as an application has made a comeback. Previously, VoD systems could only be supported on a local intranet; however, when considering deploying a global VoD service, the issue of scalability becomes important. Indeed, many low-bitrate Internet streaming services have led the way in distributed video server design. We need to re-examine the issues of designing a global VoD service that is not only scalable, but also cost effective - the most important driver in deciding whether VoD will survive its latest incarnation, or whether it will fade away to bide its time again.

description: Many effective technologies have been developed and approved for ballast water treatment, and the effectiveness of a process should be evaluated considering its environmental friendliness. The aim of this study was to evaluate the formation and formation mechanisms of bromate (BrO3−) and chlorate (ClO3−) in seawater during ozonation, electrolysis, and a combined (ozonation/electrolysis) process. In seawater ozonation, BrO3− was generated exceeding a 5 mg/L ozone dose despite the high Br− (65 mg/L). The formation of BrO3− and ClO3− by electrolysis depended on the electrode materials where two types of electrodes (IrO2/Ti and Pt/Ti) were used. The combined (ozonation/electrolysis) process generated much higher levels of BrO3− and ClO3− than either individual process. In ozonation or electrolysis, mixed oxidant including HOCl/OCl− and HOBr/OBr− is the main parameter for inactivation, which is called total residual oxidant, TRO. In this study, a predictive model for BrO3− and ClO3− was suggested in terms of TRO formation. This predictive model can recommend allowable TRO (generated by ozonation or electrolysis) for practical applications in seawater treatment.

An historical and contemporary study of technical and vocational education development in Indonesia, 1945-1990
Creators: name: Gintings, Abdorrakhman
Publisher: name: Charles Darwin University
Year: 1995

description: This study explores and analyses the development of technical and vocational education in Indonesia since its Independence (1945) to the last period of the first long term national development plan conducted by the current government (1990). There is a special emphasis on the macro contexts and the policies which have affected development. The study arose from the main research question: How effective has the development of technical and vocational education in Indonesia been since independence? This question is answered by tracing the historical development of and examining current issues concerning technical and vocational education which reveal that technical and vocational education in Indonesia in its current form was affected by two sources of education: internal or traditional education which developed from the pre historic era, and external education which was brought into the archipelago by new comers, both Asian and European. It also reveals that the development of this kind of education has been affected by the interplay of politics, security, and the economy of the country. These three macro contexts independently and in combination affect the aim, the strategy, and the development of the education system under discussion. The actual issues focused on in this study include private schools, industrial liaison, the school production unit, decentralisation of development, and employment of graduates. Regarding the improvement of compatibility between the educational program and regional needs and conditions, a regionalisation of the development of technical and vocational education with full involvement of regional educators and developers is the recommended option. The problems that are faced by the technical and vocational education system culminate in the lack of employability of the graduates including in those the fields of migrant workers and entrepreneurs. The government is committed to developing technical and vocational education to provide productive workers for national economic and industrial development. Besides allocating enormous monetary support, improvement in quality is being attempted by implementing a "link and match" strategy by which the educational program is linked and matched to the needs and conditions of the working world. To support this, managerial improvement and research that can provide a better way to approach industries is recommended in this study.

description: An imbalance in literacy and numeracy achievements of Indigenous and non-Indigenous children is of ongoing concern to educators, families and governments. The documented dissonance between backgrounds of Indigenous children, non-Indigenous teachers and school/kindergarten culture contributes to this. The early years provide foundations for future schooling; enhancing existing practices occurring across home to kindergarten is one way to approach dissonance and potentially to combat the imbalance. Despite kindergartens and schools, and by association, teachers, knowing about cultural discord, pedagogical approaches may tokenise cultural diversity. Through ethnographic fieldwork and action research this Doctor of Teaching adopted an indepth holistic view towards dissonance by focusing on embedding Indigenous children’s cultural and social practices in kindergarten curriculum and everyday pedagogy. Extending Boomer’s (1992a) concept of teacher-learner curriculum negotiation, this study places family and culture at the centre of curriculum and pedagogical decisionmaking. A collaborative process with Indigenous children, families and staff at one South Australian kindergarten produced knowledge about children’s everyday language and mathematics experiences. An investigation of similar home–community and kindergarten practices revealed the important place of relationships and interactions as cultural and social practices, where non-physical artefacts and daily lived experiences—family-ness, making choices, family roles and responsibilities and Ngarrindjeri language use—provided home-Kindergarten continuity. These, and identified mathematics practices were considered in an examination of curriculum documents which found insufficient examples of relevant local-level and explicit everyday mathematics language. This led to aligning home–community practices with mathematics in the documents and developing learning resources that showcased existing practices. This thesis is only a partial requirement of this course and the development and use of these resources accounts for the practical component. The study demonstrates that drawing on family expertise from home and curriculum expertise from kindergarten can strengthen continuity and localise the curriculum. Learning at kindergarten becomes relevant, meaningful and familiar through families, culture, prior knowledge and curriculum flexibility. It illustrates how teachers and on-site curriculum teams can share ownership of learning with Indigenous children and families by utilising their way to enrich formal learning.

description: Past applications of biosolids to soils at some locations added higher Cd levels than presently permitted. Cadmium phytoextraction would alleviate current land use constraints. Unamended farm soil, and biosolids amended farm and mine soils were obtained from a Fulton Co., IL biosolids management facility. Soils contained 0.16, 22.8, 45.3 mg Cd kg–1 and 43.1, 482, 812 mg Zn kg–1 respectively with initial pH 6.0, 6.1, 6.4. In greenhouse studies, Swiss chard (Beta vulgaris var. cicla), a Cd-accumulator maize (inbred B37 Zea mays) and a southern France Cd-hyperaccumulator genotype of Noccaea caerulescens were tested for Cd accumulation and phytoextraction. Soil pH was adjusted from ∼5.5–7.0. Additionally 100 rice (Oryza sativa) genotypes and the Ni-hyperaccumulator Alyssum murale were screened for potential phytoextraction use.Chard suffered phytotoxicity at low pH and accumulated up to 90 mg Cd kg–1 on the biosolids amended mine soil. The maize inbred accumulated up to 45 mg Cd kg–1 with only mild phytotoxicity symptoms during early growth at pH > 6.0. N. caerulescens did not exhibit phytotoxicity symptoms at any pH, and accumulated up to 235 mg Cd kg–1 in 3 months. Reharvested N. caerulescens accumulated up to 900 mg Cd kg–1 after 10 months. Neither Alyssum nor 90% of rice genotypes survived acceptably.Both N. caerulescens and B37 maize show promise for Cd phytoextraction in IL and require field evaluation; both plants could be utilized for nearly continuous Cd removal. Other maize inbreds may offer higher Cd phytoextraction at lower pH, and mono-cross hybrids higher shoot biomass yields. Further, maize grown only for biomass Cd maximum removal could be double-cropped.

Remote sensing of tree structure and biomass in north Australia mesic savanna
Creators: name: Goldbergs, Grigorijs

description: The quantification of Above Ground Biomass (AGB) plays a major role in issues related to greenhouse gas emissions and carbon sequestration, pertaining to global warming and the effects of climate change. In Eucalyptus miniata/tetrodonta dominated open-forest in Australia’s northern tropical savanna, AGB mapping is challenging, due to the complex structure of the canopy stand, highly dynamic woody cover, vast spatial extent, vulnerability to climatic effects and the impacts of extensive fire. Remotely sensed data allow for the mapping, quantification and monitoring of AGB at various scales. Quantification of AGB in tropical savanna by common medium and coarse spatial resolution optical sensor data is inappropriate to monitor finer-grained ecological processes responsible for measuring carbon stocks at an individual tree level and are limited in detecting vertical vegetation structure. There is limited research on the utility of airborne LiDAR (Light Detection and Ranging) and alternative high resolution (< 0.5 m) remote sensing tools for Australian savanna structural assessment. The main goal of this research is to evaluate the efficiency of small footprint airborne LiDAR and determine whether Unmanned Aerial Systems (UAS) and Very High Resolution (VHR) satellite stereo remote sensing data can be used to extract tree biophysical and vertical structural parameters for the purposes of accurately estimating biomass stocks in Australian mesic savannas. This study utilized a two-phase LiDAR analysis procedure integrating both Individual Tree Detection (ITC) and Area-Based Approaches (ABA) to better understand how the uncertainty of biomass estimation varies with scale. Regression analysis was applied on remote sensing data to develop biomass estimation models based on tree height allometry. This study demonstrated that where field-plot data are spatially limited, it is possible to use a hierarchical integration approach based on AGB uncertainty calculation and calibration to upscale AGB estimates from individual trees to broader landscapes. Although airborne LiDAR provided higher tree detection rates and accurate estimates of tree aboveground biomass, this research found that a 3D point cloud obtained from light-weight optical UAS imagery by an image dense matching technique is an adequate low-cost alternative for the detection of dominant and co-dominant tree stands, at least at a local scale in Australian tropical savanna. This study offers some insight into factors causing the poor dense image matching by high-resolution stereo satellites. The structural complexity of Eucalypt crowns, represented by clumped-leaf-grain structure and erectophile foliage, are the main factors determining the efficiency of tree/canopy detection using stereo satellite imagery.
Understanding and improving heifer fertility in northern Australia

description: Part of this study involved establishing current heifer fertility levels on Northern Territory (NT) commercial cattle properties. Performance recording on 14 properties found that there is scope for large improvement on many stations. Modeling showed that realistic improvements in production have the potential to increase the annual gross margin of the NT cattle industry by $10.95 million. Some of the main findings of the performance recording were that pregnancy rates in 2 year old maiden heifers are generally adequate (>75%), but foetal and calf loss rates in first calf heifers are often high (>30%) and reconception rates are often low (<20%) associated with low liveweights. Significant relationships were found between liveweights (and P8 fat depth) and pregnancy rates for Brahman heifers in the NT for; (a) yearling mated heifers grazing improved pasture, (b) 2 year old maiden heifers grazing native pasture, and (c) lactating first calf heifers grazing native pasture. Equations describing these relationships were used to produce tables which show the predicted pregnancy rates for different liveweights and fat depths in Brahman heifers in each of these situations. These tables will be useful management tools for cattle producers and advisors. They can be used in identifying target mating weights for different situations, budgeting calculations, and assessment of profitability of different scenarios etc. Other significant findings of the study were that heifers of current NT commercial Brahman genotypes reach puberty too late to enable high pregnancy rates from yearling mating, and that feeding pre-partum protein supplements to first calf heifers is one method of increasing reconception rates in the Victoria River District. This study has been successful in increasing the understanding of the relationship between mating liveweight (and fatness) and pregnancy rates in Brahman heifers and this knowledge can be applied to improve heifer performance in the NT.
On Fuzzy e-Negotiation Agents: Autonomous negotiation with incomplete and imprecise information

description: The paper presents some aspects of the customable Fuzzy e-Negotiation Agents (FeNAs) system for autonomous multi-issue negotiation in the presence of limited common knowledge and imprecise/soft constraints and preferences. The FeNAs use the principles of utility theory and fuzzy constraint based reasoning in order to find a consensus that maximizes the agent's utility at the highest possible level of fuzzy constraint satisfaction subject to its acceptability by other agents. A scenario for negotiating document translation services is used to illustrate FeNAs' capabilities for multi-issue integrative negotiation.

description: Vegetation is a primary indicator of ecosystem structure and function. In order to manage a property well managers need an accurate map of the spatial patterns of vegetation to define site-specific vegetation management practices. For scientific purposes, our goal is to determine why certain vegetation species colonize one region and not another. Preliminary models (Cornwell et al. 2012) suggest that climate, soil, and hydrology are key drivers of vegetation distribution. As the climate changes, patterns of vegetation distribution are also likely to change. In order to adaptively manage a conservation land parcel like Pepperwood, we need this data to create hypotheses about how vegetation at Pepperwood may shift in response to environmental drivers. We developed a high-resolution baseline vegetation map using a combination of eCognition software and ground-truthing methods, specifically the California Native Plant Society's Rapid Assessment Protocol. We classified each map polygon to the alliance level according to A Manual of California Vegetation. We aim to revise this map periodically to accurately measure change in vegetation distribution on the preserve over time.

description: Molecular dynamics simulations of 2-exo and 2-endo norbornyl chlorides are performed in water–acetone mixtures to investigate the role of preferential solvation on the dissociation process of norbornyl chlorides. Increase in the association constants between carbon (C2) and chloride (Cl) of norbornyl chlorides with an increase in mole fraction of acetone supports the experimental data for the corresponding decrease in the rates of solvolysis for both exo and endo norbornyl chlorides. When the mole fraction of water is increased in water–acetone mixtures, acetone molecules are replaced by water molecules around C2 as well as Cl of norbornyl chloride. Preferential solvation by water is analysed using running coordination numbers and excess coordination numbers around C2 and Cl.
