[Truncated abstract] Many soil properties are involved in supporting the growth of plants and in limiting soil degradation. The present study was carried out to provide a basis for minimising environmental impact by providing a firm understanding of the soil properties that affect plant growth for soils developed from mining waste from the Wesfarmers Premier coalmine at Collie. The purpose of this study was to provide an understanding of the soil materials and to identify the potential interactions between soil properties and plants for soils developed on coalmine materials at the Premier mine, Collie. This research was to identify the nature of the manmade soils so as to determine if soil forming processes are active, to determine soil acidity including pH buffering capacity and the lime requirement of soils, to measure water retention characteristics and soil available water for plant growth, to relate soil properties to possible effects on plant growth, and to identify management strategies to improve soil conditions and overcome plant growth constraints. Seventy-seven manmade horizons from pits in 18 constructed soils, ranging from 9 to 21-years old, were analyzed throughout this study. These samples are classified based on soil depth, layer (topsoil and subsoil), and age of soil since rehabilitation. The methods for doing most of the analyses follow the Australian Soil and Land Survey handbook by Rayment and Higginson (1992). The results are presented quantitatively and soil properties are compared to provide information on pedogenic processes, the extent of soil development, the ability of the soils to resist degradation and to provide an indication of soil parent materials

Full textAbstract:
Pedigree dog breeds are genetically isolated and inbred populations with characteristics specific to each breed. Some breeds carry genetic diseases which affect the health of the animals, but may also serve as a valuable model to identify genes involved in human disease. In the Border Collie breed in Australia, the identification of two disease genes would enable breeders to DNA test their animals and prevent future cases. Over 530 samples were collected to identify the genes responsible for these diseases through linkage mapping and candidate gene approaches. Collie Eye Anomaly (CEA) defines a group of symptoms that cause the incorrect development of different regions within the eye, and may also result in the detachment of the retina. The presence of the disease in different breeds of collies suggests that the disease originated before the differentiation of the collie breeds. The CEA gene was mapped to a region of CFA37, but the disease gene was identified by another research group. Neuronal Ceroid Lipofuscinosis (NCL) is a fatal neurodegenerative disorder that affects Border Collie dogs from approximately 16 months of age. The disease is inherited in an autosomal recessive manner and affected animals display a range of physiological and behavioural symptoms that include loss of muscular control, nervousness and sometimes aggression. Due to the debilitating nature of the disease, dogs rarely survive beyond 28 months of age. Microsatellite markers were used to exclude the Border Collie NCL gene from the region of the English Setter NCL gene (homolog of human NCL gene CLN8). Further work mapped the disease gene to CFA22, in a region containing the homolog for CLN5, one of the identified human disease genes for NCL. Subsequent sequencing of canine CLN5 revealed a nonsense mutation (c.619C>T, Q206X) that co-segregated with NCL in Border Collie pedigrees. This truncation mutation resulted in a protein product of similar size to some mutations identified in human CLN5 and therefore the Border Collie may make a good model for future NCL studies. With DNA testing now available, breeders of Border Collies can now ensure that no animal will die of NCL.

Full textAbstract:
Mesoscale airborne dispersion models are useful tools for predicting the impacts of pollutant gases from industrial emissions. This study uses the Com- monwealth Scienti¯c Industrial Research Organisation's The Air Pollution Model (TAPM) to predict sulphur dioxide (SO2) dispersion in the Collie basin, South West of Western Australia. TAPM, like most mesoscale models, poorly predict light winds (< 2ms¡1) under strongly stable atmospheric boundary layer condi- tions over complex terrain. This study alters TAPM deep soil moisture (DSM) initialisation and uses a strict spatial and temporal point and pattern sensitivity analysis and time relaxed ranked comparison approaches. It was found that mod- elled DSM did not signi¯cantly perturb TAPM meteorological outputs despite patterns indicating enhanced model performance against near surface predictions of temperature and wind direction. The DSM parameterisation resulted in im- proved prediction of highest and second highest SO2 ground level concentrations at the Collie monitoring site. The TAPM results reproduced aspects previous studies on the region and known limitations.

Full textAbstract:
[Truncated abstract] The Collie River drainage basin is an important water resource catchment in southwestern Australia. Salinisation of a major water supply within the catchment, the Wellington Reservoir, has arisen due to changes in the water and salt balance in response to land clearing over saprolite aquifers. Paired catchment studies, the Collie Experimental Catchments (CECs), established in the early 1970’s in high and low rainfall areas increased our understanding of water and salt (predominantly chloride) movement in these aquifers through the collection and analysis of high resolution spatio-temporal data. However, the conceptual models developed from this work take little account of landscape heterogeneity, and this has caused problems in subsequent modelling studies, where success in calibrating stream flow has been countered by difficulties in predicting salt loads. The challenge remains to better describe variability in the Collie landscape and understand the influence of climate, vegetation, geology and geomorphology on observed water and salt fluxes. The release of salt from the lower saprolite aquifer and the role of the surficial aquifer in buffering groundwater discharge were investigated. The acquisition, analysis and interpretation of new regolith and geophysical data in 2001-2003 from the CECs, together with data from a high resolution digital elevation model, and existing drilling information, were used to construct a geologicalgeomorphological compartment framework, to observe changes in aquifer behaviour ... Significant differences in the salt flux from compartments have been noted at a range of scales, with implications for both water resource and land management. The approach developed to identify compartments and assess their efficiency could be simplified, using catchment critical parameters determined from geological and geomorphological characteristics. As a consequence, the implementation of a compartment framework in catchments with saprolite aquifers should allow for more informed decisions to be made in the selection of sites for revegetation strategies or the development of engineering works. This is particularly important in the Collie Catchment where reclamation scenarios are currently being discussed. Consideration of the catchment as a compartmentalised system would help manage salt loads in the Collie River and return the Wellington Reservoir to a functional water resource.

Full textAbstract:
Cortisol is a stress hormone which is released from the adrenals in the Hypothalamic-Pituitary-Adrenal (HPA) axis and plays a major role in animal stress response. Cortisol is used as a stress marker and can be sampled using different methods. A good non-invasive method and a good measure of chronic stress is to measure cortisol through hair. Cortisol is stored in hair for months and therefore reflects chronic stress. The aim of this study was to investigate if cortisol concentration differs depending on coat color. Hair samples from 20 black and white Border collie dogs was analysed and used in this study. Cortisol was extracted with methanol and analysed with ELISA. The results showed no significant difference between black and white coat color within the population while there were individual differences. The results also showed that the sexes do not affect the cortisol concentration. In summary, coat color (black and white) has an effect on cortisol concentration which means that the factor color does need to be taken into account when measuring cortisol through hair.

Full textAbstract:
Resilience is a system’s ability to absorb or adapt to change without losing essential structures and functions. In a changing world, resilience assessment is a means of assessing the condition of complex ecological and social systems in the face of multiple trends and threats. This thesis examines the usefulness of resilience assessment as a policy tool when applied to communities that will be affected by policies to reduce greenhouse gas emissions, via a case study of Collie, Western Australia. A historical analysis shows that Collie’s coal industry is in the late conservation stage of an adaptive cycle and vulnerable to collapse. Current threats to the industry include climate change, greenhouse gas mitigation policies, competition from other energies, local air quality concerns, growing industrial demand for water and finite coal reserves. While some threats are volatile and therefore predictions are uncertain, these threats appear likely to push the industry into serious decline within the near to medium term (10–15 years). Collie has some capacity to adapt to such a transition, including moderate existing economic diversity and strong social capital but it appears that community awareness about the threats could be enhanced. In addition, there is evidence that perverse resilience influences energy policy in Western Australia, with persistent structures and functions that cause social and environmental harm. These are causing unequal flow of wealth and opportunity in Collie and are undermining its adaptive capacity. If new coal projects proceed, Collie will sacrifice important assets including water supplies, rivers, clean air, rural lifestyle, sense of place and heritage, along with future opportunities to diversify its economy. Alternatively, it could prepare now for inevitable transition. Resilience assessment is a useful tool for other communities that are likely to experience transition owing to climate change and resource depletion, including north-west WA towns that are also home to high greenhouse gas-intensity industries.

The subsidence characteristics of the Collie Basin sediments have been investigated to provide site specific design criteria for the Wongawilli method of coal extraction.

It was then necessary to determine the effects that mining subsidence would have on mine and ground mass (specifically aquitards) structures and surface features. Once these two areas of work were completed, design criteria were formulated to manage the effects of mining subsidence by controlling the critical mechanisms of subsidence development.The results from this study have greatly enhanced the level of understanding of the subsidence mechanisms involved, and allowed for the development of predictive models which can be used for the design of coal extraction by the panel/pillar mining method in the Collie Basin. Mine planning engineers can now use this design information to derive the most cost effective methods for the extraction of coal within the Collie Basin.

Full textAbstract:
The Early Permian coal samples for the study were obtained from the Vasse Shelf, southern Perth Basin, located approximately 200 km south- west of Perth. The selected coal samples for the study were also obtained from the Premier Sub-basin of the Collie Basin and the Irwin Sub-basin of the Perth Basin. The Early Permian coal measures are described as the Sue Coal Measures from the Vasse Shelf, the Ewington Coal Measures from the Premier Sub-basin and the coal measures from the Irwin sub-basin are described as the Irwin River Coal Measures.The Vasse Shelf coal is finely banded and the dominant lithotypes are dull and dull banded types, followed by bright banded and banded types, with minor bright types. The variation of dull and bright lithotypes represents fluctuating conditions of water table level during the growth of peat in the swamp. The maceral composition of the coal is predominantly composed of inertinite, followed by vitrinite and minor exinite and mineral matter. The coal is characterized by very low to medium semifusinite ratio and medium to high vitrinite content, supporting the deposition in anaerobic wet conditions with some degree of oxidation. The coal is classified as sub- bituminous to high volatile bituminous of the Australian classification. In terms of microlithotype group, the predominance of inertite over vitrite suggests the coal was formed under drier conditions with high degree of oxidation during its deposition. On the basis of the interpretations of lithotypes, macerals, microlithotypes and trace elements, the depositional environment of the coal is braided and meandering deltaic-river system without any brackish or marine influence.The maceral composition of the Collie coal predominantly consists of inertinite and vitrinite, with low exinite and mineral matter. The very low to low semifusinite ratio and low to medium vitrinite content of the coal indicate that the coal was formed under aerobic dry to wet conditions with some degree of oxidation. The coal is categorized as sub-bituminous according to the Australian classification. The domination of inertite and durite over vitrite and clarite contents in the coal reflects the deposition under drier conditions with fluctuations in the water table. On the basis of the interpretations of macerals, microlithotypes and trace elements distribution, the depositional environment of the coal is lacustrine, braided to meandering fluvial system, without the influence of any marine influx.The maceral composition of the Irwin River coal consists predominantly of vitrinite and inertinite, and minor exinite and mineral matter. The coal has very low semifusinite ratio and medium to high vitrinite content, suggesting the coal was deposited in anaerobic wet conditions with some degree of oxidation. The coal is classified as sub-bituminous of the Australian classification. The predominance of vitrite and clarite over inertite and durite contents in the coal indicates that the coal was formed in wetter conditions and in high water covers with a low degree of oxidation. Based on macerals and microlithotypes contents, the depositional environment of the coal is braided fluvial to deltaic, which is in accordance with the interpreted non- marine and mixed marine environment of deposition in the sub-basin.The petrological comparisons of Vasse Shelf, Collie and Irwin River coals show that the average vitrinite content of the Irwin River coal is highest (49.1%) and of the Collie coal is lowest (37.3%) of the three. The inertinite content is highest in Collie coal (49.1%), followed by Vasse Shelf (46.4%) and Irwin River (39.2%) coals. The exinite content is low in Irwin River coal (6.3%) as compared with Vasse Shelf (9.0°/,) and Collie (8.3%) coals. The mineral matter content is relatively low for all the three coals. The rank of the Vasse Shelf coal is high as compared with the Collie and Irwin River coals, either due to tectonic uplift after the deposition in post-Permian in the southern Perth Basin, or due to the average depth of burial over Vasse Shelf which is much greater than that of Collie and Irwin River coals.The comparisons of the coal from Western Australia with the selected Gondwana coals show that the predominance of inertinite over vitrinite occurs in the Western Australian coals (Vasse Shelf and Collie Basin). On the other hand, the Brazilian, eastern Australian, Indian and Western Australian (Irwin Sub-basin) coals are dominated by vitrinite over inertinite. The exinite content is highest in the Indian coals and lowest in the eastern Australian coals. The mineral matter content is highest in the Brazilian and Indian coals, and lowest in Western Australian (Vasse Shelf) and eastern Australian (Sydney Basin) coals. The rank of the coals ranges from sub- bituminous to medium volatile bituminous according to the Australian classification.

Full textAbstract:
Coal is an important part of Australia's energy mix and is expected to continue to play an essential role in supplying cheap and secure energy for powering the Australian economy in the foreseeable future. However, coal-based stationary electricity generation is a key contributor to greenhouse gas (e.g. CO2) emission, which is widely believed to be responsible for global warming and problems related to climate change. Therefore, renewable energy sources such as biomass are becoming increasingly important. In Australia, mallee biomass as a byproduct of managing dryland salinity in agricultural land is a truly sustainable second generation feedstock. Its production is economic, of large scale, high energy efficiency and low carbon footprint. Therefore, mallee biomass and its derived fuels such as biochars can potentially play a key role in the future energy mix of Australia due to significant benefits in Australia's energy security and sustainable development.Direct combustion of solid fuels (e.g. coal, mallee biomass and its derived biochars etc) is considered to be a matured technology. Coal combustion or coal/biomass co-firing is widely deployed for power generation. However, ash-related issues during solid fuels combustion are notorious and must be considered, particularly the formation/emission of fine inorganic particulate matter (PM). Fine PM is responsible for initiating ash deposition and corrosion on heat exchanger surfaces. PM emission also causes significant adverse impact to human health and environment. Despite the research progress made in this area in the past two decades, there are still significant research gaps in developing credible PM sampling method and understanding on formation/emission of inorganic PM during the combustion of biomass and/or coal.The present study aims to carry out a systematic study to obtain a thorough understanding on the emission of inorganic PM during the combustion of biomass, biochar and coal. The specific objectives of this research are to: (1) investigate the effect of sampling temperature on the properties of PM with a size less than 10μm (PM10) produced from pulverized mallee biomass combustion, then develop a proper sampling method for PM produced from the combustion of solid fuels (e.g. biomass and coal); (2) examine the emission behavior and characteristics of PM10 produced from pulverized biochar combustion, in order to provide useful data for the design of biochar-based combustion systems; (3) assess the importance and provide direct experimental evidences on the contribution of volatiles combustion to the emission of PM with a size less than 1.0μm (PM1), and to give insights into fundamental understanding on fine PM formation/emission during biomass combustion; and (4) reveal the significant roles of inherent fine included mineral particles in the emission of PM10 during pulverized coal combustion, and propose essential guideline for coal selection on its potential in fine inorganic PM emission during combustion. These objectives have been successfully achieved in this PhD study.Firstly, sampling temperature is found to influence significantly on the properties of PM10 collected from the combustion of pulverized mallee biomass. Although the yield of PM1 as well as the mass of its dominant elements (e.g. Na, K and Cl) in PM1 remain constant, the mass-based particle size distribution (PSD) of PM1 and elemental-mass-based PSDs of Na, K and Cl in PM1 shift to a larger size at a lower sampling temperature, apparently due to particulate coagulation. However, increasing sampling temperature reduces PM loss due to gravitational settling deposition, leading to an increase in the yields of the PM in a size range of 1.0 – 10 μm (PM1-10) and its dominant elements such as Mg and Ca. Both the yields of PM1-10 and the mass of Mg and Ca in PM1-10 reach constant values at sampling temperatures close to the flue gas temperature (115oC). The sampling temperatures at which drastic shifts in PSD and elemental-mass-based PSDs of PM10 take place correlate well with the SO3 dew points of the flue gas. Therefore, the sampling temperature of PM should be above the flue gas acid dew point to prevent the condensation of acid gas and furthermore be kept close to or same as the flue gas temperature in order to suppress particulate coagulation and gravitational settling deposition. Based on this important finding, a proper PM sampling method is therefore developed.Secondly, the PSD of PM10 from raw biomass combustion has a bimodal size distribution while the PSDs of PM10 from the combustion biochars generally show a unimodal distribution. Most of alkali and alkaline earth metallic species (AAEM species, mainly Na, K, Mg and Ca) are retained in the biochar during pyrolysis. However, the combustion of biochars leads to a significant reduction in the emission of PM1 (and the mass of Na, K and Cl in PM1) that dominantly consists of particles smaller than 0.1 μm (PM0.1) in comparison to biomass combustion, apparently because of the removal of volatiles and Cl from the raw biomass during pyrolysis for biochars preparation. The results imply that the combustion of volatiles (including the released inorganic species), which is particularly important during biomass combustion, is mainly responsible for PM1 emission. Meanwhile, a considerable increase in the emission of PM1-10 (and the mass of Mg and Ca in PM1-10) is also evident during biochar combustion, most likely as a result of more porous structure and increased ash loading of biochars.Thirdly, a novel two-stage pyrolysis/combustion system is therefore designed to obtain the direct experimental evidence on the contribution of volatiles combustion to PM emission. The combustion of Na-, K- and Cl-containing volatiles, which are produced in situ from the fast pyrolysis of mallee biomass, contributes substantially to PM1 emission. The PM1 yield from volatiles combustion is 77.4 – 89.3% of total PM1 collected from the combustion of both volatiles and char. Oppositely, 97.5 – 99.7% of the yields of total PM1-10 are from char combustion. An increase in pyrolysis temperature leads to an increase in the PM0.1 yields and the mass of Na, K and Cl in PM0.1 from volatiles combustion, as results of enhanced volatilization of Na, K and Cl during pyrolysis. The mass-based PSDs of PM10 and elemental-mass-based PSDs of Na, K, and Cl (which are dominantly contained in PM1) from volatiles combustion generally show a unimodal distribution with a fine mode range from ~0.022 to ~0.043 μm. The mass-based PSDs of PM10 and elemental-mass-based PSDs of Mg and Ca (which are dominantly contained in PM1-10) from char combustion also generally show a unimodal distribution but with a coarse mode of ~6.8 μm. The results clearly demonstrate that the combustion of volatiles (therefore Na, K and Cl included) produced in situ from the fast pyrolysis of biomass is a key mechanism responsible for PM1 emission.Finally, a density-separated coal sample, with a specific gravity of 1.4 – 1.6, is prepared from Collie coal. As expected, the data of computer-controlled scanning electron microscopy (CCSEM) analysis on the coal show that mineral matter in the coal is of included nature, of which ~90% are fine mineral particles <10 μm. The PM10 collected from the combustion of coal and char samples dominantly contains PM1-10, while the yields of PM1 are limited. PM1-10 contains mainly refractory species, including Si, Al, Fe, Mg and Ca. The data also show that PM1 from char combustion consists of two major fractions with different chemical composition, i.e., PM0.1 and PM in a size range of 0.1 – 1 μm (PM0.1-1). PM0.1 dominantly contains volatile elements (such as Na, K, P and S) and also some refractory elements (e.g. Fe and Si) but PM0.1-1 is mainly composed of refractory elements (Al, Fe, and Si). The vast existence of aluminosilicates in PM0.1-1 indicates the significant roles of fine included kaolinite and/or Al-silicates particles in the emission of PM1 from char combustion. Furthermore, the significant roles of inherent fine included mineral particles in PM1-10 emission during the combustion of coal and char are clearly evidenced via the identification of the presence of abundant individual but partially-molten quartz ash particles in PM1-10.

A avaliação da atividade física com o uso do acelerômetro é um método quantitativo, não invasivo, sendo mais preciso que métodos subjetivos, como questionários com proprietários, que podem muitas vezes induzir a erros. Seu uso pode ser relevante na rotina clínica para avaliações de terapias medicamentosas e cirúrgicas além de comportamentais. O presente estudo teve como objetivo quantificar a atividade física de cães da raça Border Collie que vivem em diferentes ambientes, como apartamento (grupo I), casa (grupo II), campo (grupo III) e centro de treinamento (grupo IV). Foram coletados os dados de 54 animais, sendo oito de apartamento, 18 de casa, 11 de campo e 17 em centro de treinamento de pastoreio, durante 72h com o uso do acelerômetro. O tempo de atividade sedentária foi maior em cães do grupo I em relação aos do grupo II e aos do grupo III. Já os cães do grupo IV tiveram maior tempo em atividade sedentária em relação aos do grupo III. O tempo de atividade leve a moderada foi maior no grupo III comparado ao grupo I e ao grupo IV, enquanto que o tempo de atividade vigorosa em minutos foi maior entre os cães do grupo II em relação ao grupo I. O tempo em atividade leve a moderada e vigorosa somados do grupo I foi menor que dos grupos II e III, enquanto o tempo do grupo III foi maior que do grupo IV. Contagem dos áxis integrados por minuto do grupo I foi menor tanto em relação do grupo II quanto III. Sendo assim, cães tem sua atividade física alterada conforme o ambiente e com exceção da atividade leve a moderada, animais de apartamento tem menos atividade física do que os de casa. Cães de casa e campo não tiveram nenhuma diferença de atividade física, bem como cães de apartamento e centro de treinamento nos parâmetros analisados.The use of subjective methods to evaluate levels of physical activity, as owner questionnaires, may led to misguided information. The use of the accelerometer allows physical activity to be measured quantitatively. Therefore, comparison between different published data is possible. The use of the accelerometer in the clinical practice allows evaluating the outcome of medical and surgical treatment, as so behavior changes. In this study, we report the use of the accelerometer to evaluate the level of activity of 54 Border Collie dogs. The animals were divided in four groups according to their living status: eight animals lived in an apartment (group I), 18 in a house (group II), 11 in a farm (group III) and 17 in a shepherd-training center (group IV). The accelerometer was attached to the animal’s collar for 72 hours. The group I presented longer sedentary behavior than groups II and III. Group IV presented longer sedentary behavior than group III. Group III showed longer period of light-moderate physical activity when compared to group I and IV. For vigorous intensity of physical activity, the time spent by group II was longer than group I. The total time of light-moderate and vigorous physical activity of group I was smaller than groups II and III, while group III was superior to group IV. Group I integrated axis mean counts per minute was smaller than group II and III. Therefore, dogs modify their physical activity according to their living status. Apartment subjects showed less physical activity than home subjects, except in the light-moderate category. There was no statistic difference comparing house and farm living animals, nor apartment and shepherd-training center housing.

The selected coal samples for the study were also obtained from the Premier Sub-basin of the Collie Basin and the Irwin Sub-basin of the Perth Basin. The Early Permian coal measures are described as the Sue Coal Measures from the Vasse Shelf, the Ewington Coal Measures from the Premier Sub-basin and the coal measures from the Irwin sub-basin are described as the Irwin River Coal Measures.The Vasse Shelf coal is finely banded and the dominant lithotypes are dull and dull banded types, followed by bright banded and banded types, with minor bright types. The variation of dull and bright lithotypes represents fluctuating conditions of water table level during the growth of peat in the swamp. The maceral composition of the coal is predominantly composed of inertinite, followed by vitrinite and minor exinite and mineral matter. The coal is characterized by very low to medium semifusinite ratio and medium to high vitrinite content, supporting the deposition in anaerobic wet conditions with some degree of oxidation. The coal is classified as sub- bituminous to high volatile bituminous of the Australian classification. In terms of microlithotype group, the predominance of inertite over vitrite suggests the coal was formed under drier conditions with high degree of oxidation during its deposition. On the basis of the interpretations of lithotypes, macerals, microlithotypes and trace elements, the depositional environment of the coal is braided and meandering deltaic-river system without any brackish or marine influence.The maceral composition of the Collie coal predominantly consists of inertinite and vitrinite, with low exinite and mineral matter. The very low to low semifusinite ratio and low to medium vitrinite content of ++the coal indicate that the coal was formed under aerobic dry to wet conditions with some degree of oxidation. The coal is categorized as sub-bituminous according to the Australian classification. The domination of inertite and durite over vitrite and clarite contents in the coal reflects the deposition under drier conditions with fluctuations in the water table. On the basis of the interpretations of macerals, microlithotypes and trace elements distribution, the depositional environment of the coal is lacustrine, braided to meandering fluvial system, without the influence of any marine influx.The maceral composition of the Irwin River coal consists predominantly of vitrinite and inertinite, and minor exinite and mineral matter. The coal has very low semifusinite ratio and medium to high vitrinite content, suggesting the coal was deposited in anaerobic wet conditions with some degree of oxidation. The coal is classified as sub-bituminous of the Australian classification. The predominance of vitrite and clarite over inertite and durite contents in the coal indicates that the coal was formed in wetter conditions and in high water covers with a low degree of oxidation. Based on macerals and microlithotypes contents, the depositional environment of the coal is braided fluvial to deltaic, which is in accordance with the interpreted non- marine and mixed marine environment of deposition in the sub-basin.The petrological comparisons of Vasse Shelf, Collie and Irwin River coals show that the average vitrinite content of the Irwin River coal is highest (49.1%) and of the Collie coal is lowest (37.3%) of the three. The inertinite content is highest in Collie coal (49.1%), followed by Vasse Shelf (46.4%) and Irwin River (39.2%) coals. The exinite content is low in Irwin River coal (6.3%) as compared with Vasse Shelf (9.0°/,) and Collie (8.3%) coals. The mineral matter content ++
is relatively low for all the three coals. The rank of the Vasse Shelf coal is high as compared with the Collie and Irwin River coals, either due to tectonic uplift after the deposition in post-Permian in the southern Perth Basin, or due to the average depth of burial over Vasse Shelf which is much greater than that of Collie and Irwin River coals.The comparisons of the coal from Western Australia with the selected Gondwana coals show that the predominance of inertinite over vitrinite occurs in the Western Australian coals (Vasse Shelf and Collie Basin). On the other hand, the Brazilian, eastern Australian, Indian and Western Australian (Irwin Sub-basin) coals are dominated by vitrinite over inertinite. The exinite content is highest in the Indian coals and lowest in the eastern Australian coals. The mineral matter content is highest in the Brazilian and Indian coals, and lowest in Western Australian (Vasse Shelf) and eastern Australian (Sydney Basin) coals. The rank of the coals ranges from sub- bituminous to medium volatile bituminous according to the Australian classification.

Full textAbstract:
The effectiveness of using organic matter additions to increase pH in abandoned water filled coal mining voids in Collie was investigated. Previous studies have demonstrated that passing acidic drainage through organic matter increased the waters pH. Laboratory trials using intact sediment cores (collected from Ewington, Collie, Western Australia) were used to assess the effects of additions of hay, manure and mulched vegetation on pH, nutrients an sulphate levels. In a series of experiments the effect of different quantities of organic material, sulphate reducing bacterial inoculations and alkalinity generation were measured. A subsequent field experiment was conducted to examine the impact that manure and mulch had on mine void water in 18 in situ ponds constructed adjacent to Ewington. It was concluded from the laboratory experiments that mulch and manure treatments were significantly better than hay as an organic matter addition for increasing the pH of acidified mine void water at Ewington. The manure produced the greatest increase in pH, although it contributed less to alkalinity than mulch; suggesting mulch bas a greater ability to release carbonates than did manure. The manure and mulch additions increased the pH in the laboratory and field experiment by 0.5-1.5 pH units. This increase was sustained for most of the 21 week field experiment. An increase in pH in the control ponds was recorded over the last 8 weeks of the experiment which was probably due to the inflow of more alkaline groundwater through the substratum as a consequence of the winter rainfall. pH values measured in the experimental ponds 15 months after the commencement of the project indicated that the ponds treated with manure maintained significantly higher pH levels than either the mulch or the control ponds. There was no difference between the pH values for the ponds treated with mulch and the controls suggesting that manure not only provided a greater increase in pH but also over a longer period. The addition of organic mailer also resulted in an increase in gilvin in the laboratory experiments. Low sulphate and sulphide levels were also recorded in all experiments before and after the introduction of organic materials into mine void water and ponds adjacent to Ewington indicating that sulphate reducing bacterial activity was not the cause for the increase in pH as occurred in other situations, but rather the addition of alkaline organic matter caused the increase in pH. The addition of manure organic material was associated with an increase in the ortho-phosphate levels, resulting in an increase in chlorophyll a concentrations. It is believed to be the first stages of succession processes leading to the establishment of a biologically active wetland system. During this process the emerging ecosystem neutralises the acidic content of the water.

Control of water erosion of soil at mine sites requires an ability to predict the effects of different management practices on soil loss. Using soil loss models such as the Revised Universal Soil Loss Equation (RUSLE) requires calibration of the model for materials and situations that are not defined in the models handbook or software.
The outer slopes of bauxite residue disposal areas are potentially highly erodible surfaces, and a recent evaluation of previous rehabilitation practices at Worsley Alumina, Collie, Western Australia, identified areas on the bauxite residue disposal areas where vegetation establishment and management of long term soil loss could be improved. Field experiments commencing in April 2000 at Worsley Aluminas bauxite refinery, Collie, and laboratory tilting flume experiments run at the University of Queensland, were designed to quantify the effectiveness of different surface treatments on reducing short-term soil loss, and to model long-term erosion risks.
Crushed ferricrete caprock rock-pitch and different types of mulches, seed mixes and fertiliser rates were applied to the compacted clay batter slopes used to contain bauxite residue, with runoff, soil loss and vegetation establishment monitored periodically over 27 months. Laboratory tilting flume results were related to the field data using the soil erosion models MINErosion, the Modified Universal Soil Loss Equation (MUSLE) and RUSLE to predict event-based and annual soil loss for different treatments.
Turbo-mulch, a blocky, coarse pine bark, was the most effective surface treatment for promoting vegetation establishment, reducing rill formation and reducing soil loss, a result supported in both the field and laboratory results. Turbo-mulch and vegetation did not reduce runoff, but resulted in decreased soil loss. This shows the importance of protecting soil from raindrop impact and of the soil holding capacity of vegetation. Increased seed and fertiliser rates did not significantly affect native plant numbers or foliage cover on topsoil without turbo-mulch. Rock-pitch was found to be resistant to erosion and mass movement along a rock-pitch/compacted clay interface. Field erosion measurements ranged from 0.87 t/ha/yr for turbo-mulched treatments to 7.41 t/ha/yr for a treatment with a different seed mix, lacking turbo-mulch and lacking underlying rock-pitch. RUSLE soil loss predictions based on soil properties and soil loss estimates from the MINErosion model ranged from 0.27 to 60.0 t/ha/yr. RUSLE predictions based on tilting flume data ranged from 0.14 to 81.1 t/ha/yr. RUSLE overpredicted soil loss for treatments without turbo-mulch, and underestimated soil loss for turbo-mulched treatments, necessitating calibration based on the unique materials trialed in this study.
The relative soil loss measured in the field was best represented by RUSLE predictions based on tilting flume data rather than the MINErosion model. MINErosion did not adequately describe the effect of bulk density and infiltration on soil loss of compacted/consolidated materials. MUSLE and RUSLE are adequate models for the Western Australian conditions of this study, but further research is required to calibrate the C factor for turbo-mulched surfaces and calibrate the P factor for rock-pitch.

Full textAbstract:
During the last few decades, various techniques for using lichens as biomonitors have been developed for monitoring air pollution and forest ecosystem health. Lichens have been used effectively to determine the dispersion of heavy metals emitted by industrial point-sources; however the approach has not been commonly used in Australia. This thesis aimed to determine the effectiveness of using a lichen biomonitoring approach to measure the heavy metal pollutants emitted from coal-fired power stations and related industries in Collie, south-western Australia, an area with concern over poor air quality. Three different approaches to lichen biomonitoring were investigated. The first explored lichen community composition patterns in thirty-six study sites across an identified pollution gradient in the jarrah forest ecosystems of Collie. The second measured in situ Usnea inermis lichens for heavy metals, across wet and dry seasons in Collie. The third approach used lichen transplant bags of Usnea inermis to determine seasonal heavy metal accumulation patterns. Because the gaseous pollutants NO2 and SO2 are known to have a significant effect on lichen vitality and distribution, they were monitored by means of a direct measurement approach using Radiello® passive air samplers, to determine any confounding effects. A total of twenty lichen taxa were recorded in the lichen community study, with an average species diversity of ten per site. The lichens Usnea inermis and Cladonia rigida occurred at all thirty-six study sites. High lichen diversity and abundance values were recorded from control sites, and crustose and squamulose species were more abundant across all study sites. The grouping of lichen communities into pollution-tolerant classes, based on information from other studies, showed that the jarrah forests surrounding the industries in Collie were dominated by pollution-tolerant lichen species, while sensitive species were infrequent and rare. Spatial distribution maps of lichen diversity indices showed areas with low diversity values downwind from the coal mines and coal-fired power stations and near an alumina refinery, indicating a possible influence from these point-sources on lichen community composition. Pollution effects on lichen communities were observed with little influence from forest management practices, demonstrating the effectiveness of this method for monitoring air pollution influences in managed jarrah forests. The study also identified Usnea inermis as a suitable species for both the in situ and transplant lichen biomonitoring experiments to explore heavy metal pollution in the area, because of its widespread distribution across the pollution gradient. Low concentrations of NO2 and SO2 were recorded by Radiello® passive samplers, suggesting that these pollutants had very little confounding influence on lichen community composition and heavy metal accumulation patterns. However, seasonal differences in the dispersion of gaseous pollutants were observed, particularly in the summer season. The areas influenced by gaseous pollutants were also found to be those with low lichen diversity, suggesting that although low in concentration, the gaseous pollutants were having a demonstrable influence on the lichens in the jarrah forests in Collie. Mean concentrations for the metals As, Cd, Cr, Cu, Pb, Mn, Hg, Ni and Zn were low for in situ Usnea inermis lichens; however elevated concentrations of some metals were recorded at certain locations. Arsenic concentrations in spring were high from sites close to the coal mines and Mn was elevated in both seasons from sites near an alumina refinery. Higher metal concentrations were recorded in the higher rainfall autumn season compared with spring for most metals. The fallout patterns of heavy metals were explained by a power curve showing exponential decreases in concentrations, with very low concentrations found beyond the 8 - 10 km distance range from the closest pollution source. Spatial dispersion maps showed interpolated concentrations consistent with that expected if point-sources were responsible for the generation of high atmospheric heavy metal concentrations. Transplanted Usnea inermis lichens did not show elevated metal concentrations, however seasonal variations were observed, with the highest concentrations recorded in the wet winter season. Metal uptake in both the in situ and transplanted lichen studies was favoured by low temperature and high rainfall, suggesting that metal uptake was promoted during periods of wet deposition. This highlights the importance of season of sampling if lichen biomonitoring studies are to be deployed in WA. The wetter and cooler winter season with more consistent rainfall patterns is recommended as optimal for conducting lichen biomonitoring studies in Collie. The transplants exposed over a 48 week period recorded the highest concentrations for most metals, however they also showed a loss of metal accumulation ability at the high exposure sites. Exposure periods of 24 – 32 weeks (6 – 8 months) are recommended for more reliable results when using lichen transplants. The transplant study also identified that the control sites were affected by industrial emissions, suggesting that reference sites should be located at distances greater than those used in this study. The results from all three biomonitoring approaches identified pollution dispersion patterns associated with industrial point-sources, and also identified a pollution influence at the control sites, an area previously considered to be unaffected by industrial pollution. Findings from this study support the idea that a lichen biomonitoring approach can be used as an effective tool for monitoring heavy metal air pollution in Western Australia and if used correctly it could replace the more expensive active sampling techniques. The study also provided essential baseline information for future studies on the effect of industrial pollution on lichen communities in WA.

L'ivermectine est une lactone macrocyclique antiparasitaire (nématicide et insecticide). Cette molécule est très largement utilisée en thérapeutique vétérinaire pour le traitement des parasitoses chez les bovins, ovins et équins. L'usage de l'ivermectine dans la race canine a révélé une toxicité qui affecte une sous population de la race Colley. Cette hypersensibilité à l'ivermectine semblait avoir pour origine une perturbation de l'activité d'efflux de la P-glycoprotéine. Par son action d'efflux des xénobiotiques, cette protéine membranaire contribue fortement à la fonction des barrières physiologiques qui protègent plusieurs organes vitaux. Nos investigations ont révélé que la toxicité de ces molécules chez ces chiens est due à une délétion de 4 paires de bases dans le gène MDR1 qui code pour la P-glycoprotéine. Cette mutation conduit à un décalage du cadre de lecture, qui se traduit par l'absence de la protéine chez ces animaux. La création d'une lignée cellulaire d'expression hétérologue de la P-glycoprotéine de chien, nous a permis de réaliser des études du transport des lactones macrocycliques par cette protéine dans trois espèces (homme, souris et chien). Ces études comparée de pharmacologie in vitro ont permis d'établir que: 1- En terme de spécificité de substrat, la P-glycoprotéine de chien est plus proche de la protéine murine que de la protéine humaine. Cette dernière présente un comportement singulier. .The ivermectin is an antiparasitic macrocyclic lactone (nematicide and insecticide).

Full textAbstract:
This project consists of two parts, Section One: Steel Riders, a novel for young adult readers, and Section Two: An Hermeneutical Examination q(Steel Riders. Section One: Steel Riders is a hybrid text based largely on the conventions of the detective novel. The protagonist of Steel Riders is a nineteen-year-old university student, Bella Buchanan, who returns to her home in a small industrial town in regional Western Australia. Bella is disillusioned with her life in the city, but finds that she has become alienated from the life of her peers in her home town of Sandon. This distancing of Bella allows her to observe the manners of the townspeople from the perspective of an outsider/insider. Bella's quiet life is interrupted by the arrival of her ex-boyfriend, Tallis McGuin, local Nyungah football hero who has recently joined the police force as an Aboriginal Police Aid. Bella's life is thrown into further turmoil when she begins work as a security guard at the local sand mining plant. It is here at the plant that Bella discovers a plot to conceal an important anthropological report relating to a local Nyungah burial ground. The resulting 'investigation' undertaken by Bella and Tallis into this situation results in their uncovering of local government corruption and a large, commercial marijuana plantation. This simple plot allows for a complex investigation of many issues and situations that confront young people living in regional and remote areas and at the same time celebrates the beauty of the Australian bush and the importance of community. Section Two: An Hermeneutical Examination of Steel Riders is a circular investigation of the journey to creativity which investigates the ways in which the lived experience feeds the creative impulse. The fictional town of Sandon, where Steel Riders is set, is based on the real-life coal-mining town of Collie in Western Australia where I have lived for a number of years. My experiences before I came to Collie and my "life-relation" (Bultmann, 1986, p. 243) to that town, my researches into the history of the town, and my friendships with the local residents, both Nyungah and Wadgela, are interrogated within the context of the Hermeneutic Circle and the work of Johann Martin Chladenius (1742/1986) and Johann Gustav Droysen (1858/J 986). Steel Riders features a number of Indigenous characters and I have contextualised my position as a white, female writer within a discourse of Aboriginalism as propounded by Bob Hodge and Vijay Mishra (1991 ).

Methods tested included improving spoil conditions and trialing an alternative method for seeding.Twelve species of native plants were tested for tolerance in two acid overburden materials in pot and field trials. Eucalyptus robusta is the most tolerant, Eucalyptus camaldulensis and Eucalyptus cladocalyx are highly tolerant, Eucalyptus rudis and Melaleuca hamulosa demonstrate potential, provided adequate soil moisture is available.An important growth restriction factor in acid soils is the presence of free aluminium ions. A glasshouse trial performed on seven species for tolerance to aluminium toxicity revealed E. robusta as most tolerant and E. camaldulensis and Kunzea ericifolia a highly tolerant. E. rudis and M. hamulosa are moderately tolerant, but E. cladocalyx and Eucalyptus diversicolor are very sensitive to aluminium.Various methods were trialed to increase growth of seedlings transplanted on to acidic overburden sites. Both commercial cow manure and slow-release fertiliser tablets increase growth, whereas commercial potting mix and lime do not. Inoculation of plants with the ectomycorrhiza fungus Pisolithus tinctorius increases the amount of infection in roots but does not enhance plant growth.Supplementary fertilisation is necessary to maintain growth (nitrogen) and restore chlorophyll production (phosphorus) in fast growing eucalypt seedlings planted into typical acidic spoils. Poor levels of nutrient availability in such acidic sites appear to be the primary factor in retarding growth. In the absence of supplementation, foliage reddening is observed in several species.An alternative method of seeding dumps is fascining. Prepared dump surfaces may be covered with capsule-laden branchwood of myrtaceous species. Material of the locally available Kunzea ericifolia is effective in producing many seedlings. Subsequent seedling growth is enhanced with fertiliser and lime addition.

Full textAbstract:
[Truncated abstract] During the last fifty years mathematical models of catchment hydrology have been widely developed and used for hydrologic forecasting, design and water resources management. Most of these models need large numbers of parameters to represent the flow generation process. The model parameters are estimated through calibration techniques and often lead to ‘unrealistic’ values due to structural error in the model formulations. This thesis presents a new strategy for developing catchment hydrology models for representing streamflow and salinity generation processes. The strategy seeks to ‘learn from data’ in order to specify a conceptual framework that is appropriate for the particular space and time scale under consideration. Initially, the conceptual framework is developed by considering large space and time scales. The space and time scales are then progressively reduced and conceptual model complexity systematically increased until ultimately, an adequate simulation of daily streamflow and salinity is achieved. This strategy leads to identification of a few key physically meaningful parameters, most of which can be estimated a priori and with minimal or no calibration. Initially, the annual streamflow data from ten experimental catchments (control and cleared for agriculture) were analysed. The streamflow increased in two phases: (i) immediately after clearing due to reduced evapotranspiration, and (ii) through an increase in stream zone saturated area. The annual evapotranspiration losses from native vegetation and pasture, the ‘excess’ water (resulting from reduced transpiration after land use change), runoff and deep storage were estimated by a simple water balance model. The model parameters are obtained a priori without calibration. The annual model was then elaborated by analysing the monthly rainfall-runoff, groundwater and soil moisture data from four experimental catchments. Ernies (control, fully forested) and Lemon (53% cleared) catchments are located in zone with a mean annual rainfall of 725 mm. Salmon (control, fully forested) and Wights (100% cleared) are located in zone with mean annual rainfall of 1125 mm. Groundwater levels rose and the stream zone saturated area increased significantly after clearing. From analysis of this data it was evident that at a monthly time step the conceptual model framework needed to include a systematic gain/loss to storage component in order to adequately describe the observed lags between peak monthly rainfall and runoff.

A glasshouse trial performed on seven species for tolerance to aluminium toxicity revealed E. robusta as most tolerant and E. camaldulensis and Kunzea ericifolia a highly tolerant. E. rudis and M. hamulosa are moderately tolerant, but E. cladocalyx and Eucalyptus diversicolor are very sensitive to aluminium.Various methods were trialed to increase growth of seedlings transplanted on to acidic overburden sites. Both commercial cow manure and slow-release fertiliser tablets increase growth, whereas commercial potting mix and lime do not. Inoculation of plants with the ectomycorrhiza fungus Pisolithus tinctorius increases the amount of infection in roots but does not enhance plant growth.Supplementary fertilisation is necessary to maintain growth (nitrogen) and restore chlorophyll production (phosphorus) in fast growing eucalypt seedlings planted into typical acidic spoils. Poor levels of nutrient availability in such acidic sites appear to be the primary factor in ++retarding growth. In the absence of supplementation, foliage reddening is observed in several species.An alternative method of seeding dumps is fascining. Prepared dump surfaces may be covered with capsule-laden branchwood of myrtaceous species. Material of the locally available Kunzea ericifolia is effective in producing many seedlings. Subsequent seedling growth is enhanced with fertiliser and lime addition.

Les paramètres des adhésifs commerciaux qui minimisent ou maximisent ce type de fluage ont été identifies. Le travail présente la corrélation de la structure des adhésifs, leur fluage et leur fluage dépendent de la température pour applications structurelles. Ce travail a conduit à l’établissement des principes de formulation et reformulations de adhésifs sans fluage ou avec un fluage minimal.

Testing of the best standards-approved commercial polyurethane adhesive for this purpose showed that while ambient temperature creep is limited this is not the case for temperature-dependent creep. The commercial adhesives characteristics that minimize or enhance ambient temperature and temperature-dependent creep were identified. The work encompass the correlation of structure, creep and temperature-dependent creep for polyurethanes for structural wood application. This was done to establish basic principles in order to formulate and to reformulate the existing “creeping” formulations so that the problem can be eliminated or at least minimized. Basic principles on the structure of simple polyurethane adhesives influencing temperature-dependent creep were also identified and discussed

As efforts to provide seamless transitions from high school to college grow, so do the numbers of high school students who concurrently enroll in college courses across the country. The purpose of this study was to evaluate the effectiveness of various aspects of the concurrent enrollment program at Collin County Community College District in Texas. Six research questions were designed to address student success and continuing enrollment patterns after high school graduation, as well as evaluate differences in the various models of dual credit classes offered by the college. Literature related to concurrent enrollment and dual credit programs, senior year of high school, and part-time faculty effectiveness was reviewed. Student issues addressed include: grade performance of concurrent enrollment students compared to the general college population; the percentage of concurrent enrollment students who continue at the college after high school graduation; and a comparison of continuing concurrent enrollment students with a matched sample (based on high school class rank), on the student success factors of fall-to-spring retention rates, fall-to-fall retention rates, grade point averages, and completion rates. Findings were generally positive related to the impact of concurrent enrollment on students and their subsequent success at the college. Various models of offering concurrent enrollment courses were also evaluated as measured by student performance in subsequent courses. Analysis of variance was used to determine differences based on the location at which the courses were taught (high school, college campus, or a college center); differences based on the mix of students in the class (all from one high school; all high school representing several schools; or a mix of high school and college students); and differences based on the employment status of the instructor (full-time college instructor; part-time college instructor; or high school teacher). Differences were examined for the entire sample, and for the academic disciplines of economics, English, and government.

Full textAbstract:
« Revoluflex » est un procédé de contre-collage de films plastiques par l'intermédiaire d'une fine couche d'adhésif thermofusible. Dans ce procédé, l'adhésif fondu est extrudé à travers une filière plate (entrefer ~ 1 mm) puis étiré dans l'air sur une très courte distance (~ 1 mm) à des taux d'étirage très importants (Dr>100) et enfin déposé sur le film plastique primaire. Une pompe à vide, placée au-dessous du film extrudé, permet de stabiliser le procédé et d'empêcher l'admission de bulles d'air entre le film primaire et l'adhésif. Un film plastique secondaire est ensuite déposé sur le film primaire pour former le film complexe. En fonction des paramètres du procédé, plusieurs défauts sont observés. Par exemple, on observe dans certaines conditions des surépaisseurs périodiques dans la couche d'adhésif qui s'apparentent à une instabilité d'étirage appelée Draw Resonance. D'autres défauts qui correspondent plutôt à des déchirures dans le film adhésif sont également observés. Ces défauts représentent un obstacle pour le développement de ce procédé innovant et donc l'enjeu de cette étude consiste à comprendre l'origine de ces défauts afin de pouvoir les supprimer ou, au moins, en différer l'apparition.Pour ce faire, ces défauts ont tout d'abord été caractérisés et leur apparition a été quantifiée en fonction des paramètres du procédé et de la rhéologie de différentes formulations d'adhésif.Des modèles de complexité croissante, tant au niveau de la description cinématique de l'écoulement que de la loi de comportement du polymère, ont été développés. Des modèles membrane Newtonien et viscoélastique à largeur constante où un différentiel de pression est appliqué entre les deux faces du film extrudé constituent une première approche théorique qui rend compte de l'effet de la pompe à vide. La méthode de stabilité linéaire a été utilisée pour prédire le phénomène d'instabilité périodique en fonction du comportement rhéologique et des paramètres du procédé. Notre étude a montré que les résultats de ces modèles membrane sont très influencés par les conditions initiales de l'écoulement. Comme l'hypothèse membrane n'est plus valide à de très courtes distances d'étirage, nous avons développé deux modèles 2D Newtonien qui rendent compte à la fois de l'écoulement dans la filière et au cours de l'étirage. Le premier modèle symétrique ne prend pas en compte l'effet de la pompe à vide mais et a été résolu avec deux approches différentes : une méthode de suivi d'interface couplée à la méthode de stabilité linéaire et une méthode de simulation directe par capture d'interface (méthode Level-Set). Nous avons montré que ces deux méthodes permettent d'obtenir la même solution stationnaire et les mêmes résultats de stabilité. Le deuxième modèle prend en compte le différentiel de pression et a été résolu uniquement par la technique de suivi d'interface couplée à la méthode de stabilité linéaire. Ce modèle 2D permet également de trancher entre les différentes conditions initiales testées avec le modèle membrane.Ces modèles permettent d'expliquer plusieurs phénomènes observés expérimentalement comme l'effet stabilisant du différentiel de pression et de la courte distance d'étirage. De plus, ils mettent en évidence un résultat paradoxal qui est l'effet stabilisant du taux d'étirage dans certaines conditions opératoires. Ils montrent enfin que le différentiel de pression provoque une contrainte très élevée au niveau de la lèvre inférieure de la filière, ce qui peut être une explication des déchirures observés dans la couche de colle“Revoluflex” is an innovative laminating process consisting in bonding two plastic films with a thin layer of hot melt adhesive. The molten adhesive is extruded through a flat die (gap ~ 1 mm). Then, it is stretched into the air at very high draw ratio (Dr> 100) over a very short distance (~ 1 mm) and set down on the primary plastic film. A vacuum pump, located beneath the extruded film, stabilizes the process and prevents air bubble intake between the primary and the adhesive film. A secondary plastic film is then laid on the coated primary film to give a laminate. Many defects can be observed as a function of the process parameters such as wavelike instabilities characterized by periodical sustained oscillations in the hot melt adhesive layer. This instability is similar to the “Draw Resonance” instability encountered with classical processes involving the stretching of a molten polymer. Other defects looking like small bubbles, cracks or rips in the adhesive layer are also observed. These defects hinder commercial deployment of the process. The aim of this study is there to understand their origins in order to remove them or at least delay their onset.These defects have first been characterized and their appearance was quantified according to process parameters and adhesive rheology. Several theoretical models of increasing complexity, in terms of flow kinematics and polymer rheology, have been developed. Newtonian and Viscoelastic constant width membrane models involving a pressure differential between the two sides of the extruded film represent a first theoretical approach that accounts for the vacuum pump effect. The linear stability method was used to investigate the influence of adhesive rheological behavior and process parameters on the onset of periodic instabilities. It was shown that the results were highly dependent on the initial flow conditions at die exit. Since the membrane assumption is not valid for very short stretching distances, we developed two Newtonian 2D models accounting for both extrusion and drawing steps. The first one is a symmetric model that does not account for the vacuum pump effect. It was solved using two different approaches: a front-tracking method coupled with linear stability analysis and a direct numerical simulation with interface capturing method (Level set method). It was shown that both methods lead to the same stationary solution and the same stability results. The second model accounts for the pressure differential and it was solved using only the front-tracking method. This latter 2D model enables to check the validity of the initial flow conditions of the membrane model.These models allow us to explain several experimental phenomena such as the stabilizing effect of the pressure differential and the short stretching distance. In addition, they help explaining experimental features which contradict the classical literature on drawing instabilities such as the stabilizing effect of increasing the draw ratio under certain operating conditions. Finally, they show that the pressure differential induces a high stress at the bottom lip of the extrusion die, which may clarify the cracks and rips observed in the adhesive layer

L’enoturismo sancisce l’unione di due realtà, quella del turismo e quella del vino, che hanno implicazioni sostanziali per l’economia, l’ambiente e la società, particolarmente nel nostro Paese. Infatti, se programmate e gestite in modo sostenibile, in un’ottica competitiva ed integrata, fungono da traino per lo sviluppo delle aree rurali, fondamentali per diversificare l’offerta e riscoprire tutta una serie di valori, pratiche, tradizioni e antichi sapori da poter offrire al turista. Questa trattazione cercherà di evidenziare le motivazioni per le quali l’enoturismo rappresenta la sintesi perfetta tra una tipologia di turismo responsabile e benefica per la comunità e un prodotto d’eccellenza che racconta la storia del territorio italiano a tutto il mondo. Si tratta di un fenomeno il cui sviluppo è abbastanza recente ma in continua crescita, anche per il supporto delle numerose associazioni, manifestazioni ed eventi legati ad esso, che contribuiscono a coinvolgere la comunità locale. Tra le regioni che portano avanti la bandiera dell’enoturismo in Italia compare sicuramente il Veneto, terra madre del Prosecco, legato quindi soprattutto alla zona di Conegliano e Valdobbiadene. È importante riconoscere però anche le altre ricchezze ed eccellenze del territorio, in questo caso quelle dei Colli Berici ed Euganei nelle province di Vicenza e Padova. Attraverso le piccole ma preziose aziende vitivinicole che costellano il territorio e la particolarità dei loro paesaggi, associati chiaramente a vini autoctoni di qualità, questi territori possono rappresentare una valida alternativa alle mete più visitate della regione, in un’ottica di diversificazione dell’offerta e di valorizzazione di zone potenzialmente fruttuose. Si descriveranno e analizzeranno quindi i territori interessati e le possibilità che sono in grado di offrire, per poi tradurre sul piano pratico le azioni che gli enti interessati dovrebbero perseguire. Infine, tramite l’analisi di due piccole aziende viticole si evidenzierà l’importanza di queste ultime per la valorizzazione dell’intero territorio.

Full textAbstract:
This project is an investigation of a cosmological model consisting of a five dimensional AdS-vacuum with a flux. By discharges in the flux, four dimensional bubbles can nucleate in the vacuum and collide with each other while expanding. Our observable universe is considered to be localized on the membrane of such a bubble. The main purpose of the model was to find a possible explanation for dark energy and inflation. We compute the Friedmann equation for an expanding bubble, as well as analytical expressions for the two slow roll parameters ε and η related to slow roll inflation. We also show that there exists a set of parameters of the model where both slow roll parameters are small enough in order for inflation to last for at least 60 Hubble times. However, our model doesn’t survive all consistency checks with today’s observations. We conclude that even if the resulting slow roll parameters look promising, one has to either look harder for a set of ”good” fundamental parameters of the model, or further develop it to have a chance of surviving all consistency checks.Populärvetenskaplig sammanfattning: Det här projektet undersöker en kosmologisk modell bestående av ett femdimensionellt vakuum med negativ rumtidkrökning. I vakuumet finns ett elektriskt fält, som i högre dimensioner än fyra kallas flux (flöde). Urladdningar i detta flux gör det möjligt för fyrdimensionella bubblor att uppstå i vakuumet. Dessa vakuumbubblor expanderar snabbt och kommer så småningom att kollidera med varandra. Tanken är att vårt fyrdimensionella observerbara universum utgör en del av membranet på en av dessa expanderande vakuumbubblor. De andra vakuumbubblorna kan - om man vill - betraktas som parallella universum. Målet med detta projekt har varit att hitta en möjlig model för kosmisk inflation - epoken i vårt universums ungdom då rummet expanderade enormt snabbt under en väldigt kort tidsperiod. Inflationen i vår modell äger rum när vakuumbubblan för vårt universum kolliderar med andra vakuumbubblor. Vi lyckades visa att den här modellen kan ge upphov till inflation som varar tillräckligt länge för att det ska stämma överens med dagens observationer av vårt observerbara universum. Dock förutspår modellen även andra saker som inte stämmer överens med observationerna. Vår slutsats är att modellen ser lovande ut, men att man antingen behöver undersöka den noggrannare eller utveckla den på något sätt, om den ska ha en chans att stämma överens med universumet vi observerar.

The Australian soprano Marie Collier (1927-1971) is generally remembered for two things: for her performance of the title role in Puccini’s Tosca, especially when she replaced the controversial singer Maria Callas at late notice in 1965; and her tragic death in a fall from a window at the age of forty-four. The focus on Tosca, and the mythology that has grown around the manner of her death, have obscured Collier’s considerable achievements. She sang traditional repertoire with great success in the major opera houses of Europe, North and South America and Australia, and became celebrated for her pioneering performances of twentieth-century works now regularly performed alongside the traditional canon. Collier’s experiences reveal much about post-World War II Australian identity and cultural values, about the ways in which the making of opera changed throughout the world in the 1950s and 1960s, and how women negotiated their changing status and prospects through that period. She exercised her profession in an era when the opera industry became globalised, creating and controlling an image of herself as the ‘housewife-diva’, maintaining her identity as an Australian artist on the international scene, and developing a successful career at the highest level of her artform while creating a fulfilling home life. This study considers the circumstances and mythology of Marie Collier’s death, but more importantly shows her as a woman of the mid-twentieth century navigating the professional and personal spheres to achieve her vision of a life that included art, work and family.

The research examined the individual and collective influence of ‘Indigenous status’ and ‘remoteness’ on road crash profiles. Interviews with 229 crash patients recruited through health facilities in North Queensland showed that involvement of unsafe behaviours in crashes increased with remoteness, and were more marked among Indigenous patients (proximal causation). Themes identified as influencing behaviour included social acceptance of risk (‘rural way of life’), bravado among young males and feelings of hopelessness among the Indigenous sample (distal causation). Using this knowledge, recommendations are provided under the ‘Safe System’ framework with a particular focus on improving Indigenous program development and delivery.

Les cas de la structure dans le vide et celui de la structure dans un fluide sont étudiés. Les résonances de la structure sont étudiées soit par la recherche de pôles dans le plan complexe soit en utilisant le formalisme de la Matrice S. L’évolution des fréquences et des largeurs des résonances est donnée. La couche de couplant est considérée comme un milieu cubique ou un milieu transverse isotrope. Les modes verticaux et l’évolution des modes au voisinage de l’angle de Rayleigh sont spécialement étudiésThe propagation of Lamb waves in a trilayer structure composed by two isotropic plates coupled by an anisotropic thin layer is studied in the thesis. The initial adressed problem was : how the Lamb waves are affected by the consideration of the effects of the anisotropy of the thin layer acting as glue between the plates ? The cases of the stucture in vacuum and in a fluid are treated. The resonances of the structure are analysed either by searching poles in complex planes or by using the S matrix formalism. The evolution of their frequencies and their widths is given. The thin layer is considered either like a cubic or a transverse isotropic medium. The isotropic plates can be identical or different. The “vertical modes” and the evolution of the modes at the vicinity of Rayleigh angles are specially studied

This thesis will explore Watchmen as an event in postmodern art and literature. When a postmodern event occurs, no language game exists at that moment to make the event comprehensible. Limitations therefore of incommensurable language games are exposed and scholars are left without language, scrabbling to decipher what happened. This is the case with Watchmen. Comics and literature collided and there is no language to discuss what has come out of that collision. Through chapter analysis, character study, and inquiry into the postmodern mood this project will demonstrate Watchmen as a turning point in the discussion of comics and literature.

Full textAbstract:
The focus of this work is the attempt to detect gravitational waves emitted by compact binary coalescences (CBCs) using gravitational wave interferometers. We begin by reviewing the basic theory of gravitational waves and the methods for their detection, focusing on CBCs. We also briefly describe the laser interferometers that are being used to attempt to detect gravitational radiation. We describe in detail the search pipeline that has been used to search for gravitational waves emitted from CBCs in data taken by the LIGO and Virgo detectors. We present the latest results of the all-sky, all-time search and electromagnetically triggered searches. We introduce a fully coherent, multi-detector analysis that can be used to search for CBC signals in coincidence with electromagnetically observed events. Using a number of signal consistency tests, including a coherent extension of the often used x2 test, we demonstrate that the coherent search offers an improvement in sensitivity when compared to the previous search method. Additionally we describe an extension of the coherent search that can be used to search for CBC signals where one of the components has spin. This method is well suited to searches for neutron star, black hole binaries. We introduce a "stochastic" algorithm that can be used to create template banks in arbitrary parameter spaces of arbitrary dimension. We demonstrate this method in a search for super-massive CBCs in the mock LISA data challenge. Finally, we present the black hole hunter game, which has been widely used in outreach projects.

Des résines « vertes » à base de lignine, tanins et protéines de soja ont été étudiées. La faisabilité et le mécanisme de l’utilisation du glyoxal à différents taux en substitution du formaldéhyde ont été analysés. Une optimisation dans la préparation des panneaux de particules à été réalisée. Les résultats issus de ces travaux confirment les quelques aspects: Des colles à base de lignine et de soja glyoxalé mélangé à la pMDI et au tanin de mimosa satisfaisant les exigences données par les normes internationales pour la fabrication des panneaux de particules ont été obtenues. Aucun formaldéhyde n’a été utilisé dans les formulations. La performance a été déterminée en majeure partie en fonction de la proportion de pMDI ajoutée. Les résultats obtenus prouvent l’existence de réactions entre lignine et glyoxal, protéines de soja et glyoxal. Mais pour la formulation de protéines de soja, les groupes hydroxyles qui en résultent n’ont pas pu réticuler. Des études ont été effectuées sur l’influence de la nano-montimorillonite (MMT) sur des résines à base d’urée et de phénol-formaldéhyde. Le taux d’exfoliation de la MMT mélangée avec ces résines était déterminé. Des études thermiques et mécaniques de ces systèmes ont été réalisées. Les conclusions obtenues sont les suivantes : L’étude que la Na-MMT est intégralement exfoliée quand elle est mélangée avec des résines UF, alors qu’elle n’a que quelques degrés d’intercalation lorsqu’elle est ajoutée à des résines PF ou PUF. L’ajout d’un faible pourcentage de Na-MMT ne semble pas modifier significativement la performance des résines sèches mais la résistance à l’eau des panneaux contenant des résines UF ou phénolique s’est vue augmenterEnvironment-friendly tannin/lignin and soy protein-based wood adhesive were studied. The feasibility and mechanism to use glyoxal to substitute formaldehyde in relevant formulations was analyzed. The suitable addition percentage was determined. The lab-prepared particleboard procedure was optimized too. The results shown in this work confirmed few aspects: Lignin-based adhesives and glyoxalated soy-based wood adhesives mixed with pMDI and mimosa tannin satisfying the requirements of relevant international standards for the manufacture of wood particleboard were obtained. These lignin-based or soy-based wood adhesives did not use any formaldehyde in their formulation. The performance of these formulations is determined to a great degree by the amount or proportion of the pMDI used. The results proved that the reaction between lignin and glyoxal, soy protein and glyoxal. But for the latter, the hydroxy groups that resulted couldn’t condense to a cross-linked structure. Some work has been done on the study of the influence of nano-montmorillonite (MMT) on urea-formaldehyde resin and phenolic resin adhesives. The level of exfoliation of the MMT being mixed with these resins was determined. Some conclusions can be drawn: Na-MMT is completely exfoliated when mixed with UF resins, while it only has some degree of intercalation when added to PF and PUF resins. The addition of small percentages of Na-MMT does not appear to improve much the resins dry performance, while it seems to increase the water resistance of the UF-bonded and phenolic-bond panels

Full textAbstract:
This is a work of local history examining the course of Reconstruction in Collin County, Texas. National and state level surveys of Reconstruction often overlook the experiences of communities in favor of simpler, broader narratives. The work proceeds chronologically, beginning with the close of the Civil War, and tells the story of Collin County as national Reconstruction progressed and relies on works of professional and non-academic historians, oral histories, census data, and newspapers to present a coherent picture of local life, work, and politics. The results exemplify the value of local history, as local conditions influenced the course of events in Collin County as much as those in Austin and Washington D.C. The story of Reconstruction in Collin County is one of anomalous political views resulting from geographical exclusion from the cotton culture of Texas followed by a steady convergence. As Reconstruction progressed, Collin County began to show solidarity with more solidly conservative Texas Counties. The arrival of railroads allowed farmers to move from subsistence agriculture to cash crop production. This further altered local attitudes toward government, labor, voting rights, and education for Freedmen. By the end of Reconstruction, Collin County had all but abandoned their contrarian social and political views of the 1850s and 1860s in favor of limited rights for blacks and Redemption. The results show the importance of local history and how Collin County’s Reconstruction experience enriches and deepens how historians view the years after the Civil War. The author recommends further research of this kind to supplement broader syntheses.
