Full textAbstract:
This thesis examines existing rehabilitation and environmental guidelines to determine whether the guidelines are incorporating the necessary building science knowledge to ensure that insulation is performing as intended and thus promoting energy efficiency, cost effectiveness, and environmental sustainability. The results of analyzing the existing guidelines show that they do not require all that is necessary to promote energy efficiency and environmental sustainability. While several of the guidelines have started to incorporate the necessary building science perspective by requiring a whole house air leakage test, none of the guidelines examined specifically require the zonal pressure diagnostics test necessary to ensure that insulation is working to specification. The thesis also includes a comprehensive overview of environmental sustainability and rehabilitation.Department of Urban Planning

Full textAbstract:
Currently in Western Australia there are no mandated standards for assessing rehabilitation success for the mining industry. A decade ago the focus of most mine site rehabilitation programs was to establish good density and cover of vegetation across the disturbed area. While this resulted in rehabilitated sites that were essentially stable and may have looked aesthetically pleasing, it did not necessarily mean that the rehabilitated sites were moving towards the establishment of functional ecosystems. The goal for rehabilitated mined land should be to restore the structure, diversity, function and dynamics, of the undisturbed ecosystem. In many circumstances this will mean the creation of a self-sustaining, functional ecosystem similar to that in the adjacent undisturbed area from which the rehabilitated area will recruit most of its fauna. The need for 'high-quality' rehabilitation has become necessary with the phasing in of performance standards for assessing the development of rehabilitated mine sites. Mine site rehabilitation should be viewed as managing succession processes towards the creation of ecosystems that are functionally compatible with that which existed before the disturbance or in the adjacent undisturbed areas.

As a result, there is an ever growing number of rehabilitated historic buildings in the United States not only incorporating sustainable building designs but also achieving Leadership in Energy and Environmental Design (LEED) certification. Most of these are large, architect-designed buildings in urban settings rehabilitated for cultural and commercial uses. This thesis explores the application of the LEED 2009 New Construction and Major Renovation Rating System for the development of a sustainable rehabilitation plan for the modest vernacular 1897 Jeff.

Full textAbstract:
Background Exhaustion disorder (ED) is a common mental and behavioural disorder which often leads to severe negative consequences for the individual and the society. Natural environments have positive effects on mental, physiological and attentional recovery in stressed persons, which encouraged us to test if forest visits could improve recovery from ED. The main objective of the thesis was to study if visits to different kinds of forest environments have positive health effects on patients suffering from ED, and if forest visits can be utilized for rehabilitation. Methods Participants in the MiniRest study (n=20) and the Pilot study (n=6) (Papers I and II) were recruited from the Stress Rehabilitation Clinic (SRC) at the University Hospital in Umeå. Participants in the randomised controlled study, ForRest (n=99) and the Interview study (n=19) (Papers III and IV) were recruited from both the SRC and the Swedish Social Insurance Agency in Umeå. The MiniRest study involved only female ED patients and focused on immediate mental, physiological and attention capacity effects in one urban and three forest environments. The Pilot study investigated the practical arrangements for the forthcoming ForRest study. Participants in the ForRest study were randomised into either a three-month forest rehabilitation group; A (forest visits twice a week/4 hours per day) or to a control condition; B. Both groups received Cognitive Behavioural Rehabilitation (CBR) at 24 occasions/once a week after the three-month study period. Preferences for forest environments, mental state and attention capacity were studied for group A only. Psychological health measurements and sick leave data were compared between the groups after (i) the forest rehabilitation and (ii) the CBR. The Interview study was conducted according to grounded theory methodology and consisted of 19 participants from group A to explore personal experiences from the forest rehabilitation. Data collection was implemented through questionnaires, medical records, physiological measurements, and interviews. Results Exposure to forest environments was associated with higher preference, more favourable mental state and physiological responses, and increased attention capacity compared to an urban environment (Paper I). Open and accessible forest environments were preferred (Papers I, II and III). Recovery from ED was found in both groups in the ForRest study, but there were no differences between the groups over time. In group A, positive effects on mental state and attention capacity were found during the forest visits. An interaction effect was found with more positive effects on mental state during spring compared to autumn (Paper III). Solitude, feelings of freedom and no demands were important for finding peace of mind during the forest visits. Moreover, easier access to peace of mind, reflective thinking and positive feelings were reported as the forest rehabilitation progressed (Papers II and IV). Conclusions Forest visits have restorative effects for ED patients through enhanced mental well-being, easier access to peace of mind, beneficial physiological reactions and increased attention capacity which support the use of forest environments in rehabilitation. However, forest rehabilitation tested in a randomised controlled trial did not improve recovery from ED. Potentially rehabilitation with CBR and forest visits integrated could be more effective and should be further investigated in nature-assisted rehabilitation for ED patients.

Full textAbstract:
Rehabilitation is a dynamic process influenced by factors related to more than one field of ecology. It is therefore necessary to consider all these components when assessing the rehabilitation, although in the initial stages the successful revegetation of the disturbed areas is the most important criterion. Richards Bay Minerals, on whose mining site this project was carried out, is dredge mining heavy minerals on the north coast of Natal, where they have rehabilitated mined areas since 1978. This project has been carried out to establish: 1) The success of their dune forest rehabilitation using quantitative techniques. 2) The available seed bank in their rehabilitation stands. 3) The similarities in the succession taking place in rehabilitation stands compared to the revegetated stands in the vicinity of Richards Bay. 4) The best methods for creating alternative vegetation communities, especially grasslands, with a high species diversity on the mined tailings. This study reviews only the success of rehabilitation of the natural vegetation but other studies focusing on the insect, reptile, mammal and bird populations are also being undertaken by other researchers. No particular method of determining the success of vegetation rehabilitation has been chosen by restoration ecologists. Therefore in this study a broad range of quantitative techniques were used to show whether successional changes are occurring in the vegetation and physical environment. The results obtained from sampling the rehabilitated vegetation have shown that both the species richness and diversity are increasing as the returned vegetation matures. Levels of soil properties such as Sodium, Phosphate, Calcium and percentage organic matter have also risen with increasing stand age. Community complexity is also increasing with stand age, and TWINSPAN and DECORANA plots have separated out the differently aged stands based on their differences. A "pilot" study was done on the seed bank present in the rehabilitation stands. This has shown the presence of large amounts of early successional, mostly herbaceous species. Seeds of later successional and woody species were scarce which may be a result of the sampling intensity used. However seeds of late successional ground cover species were found in the older stands. Comparisons between the natural revegetation of disturbed areas in the vicinity of Richards Bay and the rehabilitation stands revealed similarities in both species composition and complexity. Species richness and diversity values are comparatively similar for the younger revegetated and older rehabilitation stands, and lWlNSPAN and DECORANA analysis techniques clustered the samples recorded from these areas in close proximity on their relative plots. The oldest revegetated sites contain a number of species found in the rehabilitated vegetation but as Acacia karroo has thinned-out in these stands many of these other species are now mature individuals. Attempts at rehabilitating an area of grassland at Richards Bay Minerals has not produced satisfactory species diversity and experimental manipulations were used to try and increase the diversity of the existing Eragrostis curvula dominated community. Of the several treatments used for the manipulation, a combination of burning and further topsoiling was the most successful in reducing Eragrostis importance and in increasing the species richness. Grassland topsoil spread directly onto the bare tailings produced an extensive vegetation covering over a short period but species richness was not significantly greater than for the existing Eragrostis dominated grassland, and further treatments and management needs to continue if this technique is to be employed. Only a limited amount of alien infestation of the rehabilitated areas was evident from the sampling undertaken during this research. As the removal of alien plants is an ongoing process and the rehabilitation stands are continuously monitored to identify any new invaders, this is not expected to become a problem. From the results of work done overseas and the rehabilitation carried out in South Africa it appears that it is possible to return natural vegetation communities on mined areas. That this is a lengthy process is to be expected but by manipulating the vegetation and continuously monitoring the process it may be possible to speed up development. Areas in need of further research have been identified based on the findings of this project. This will help to reinforce the undertaking of management proposals that will enhance the vegetation recovery and the success of the rehabilitation programme.

Thesis (MScConsEcol(Conservation Ecology and Entomology)--University of Stellenbosch, 2006.Anglo American Corporation’s Namakwa Sands heavy minerals mining and beneficiation operation has been strip-mining a heavy mineral deposit, rich in the commercially valuable minerals ilmenite, rutile and zircon, since September 1994. The mine is located in the vicinity of Brand-se-Baai on the west coast of South Africa, approximately 385 km north of Cape Town. Strip-mining causes total destruction of natural ecosystems through the removal of vegetation and soil in the area where mining is being undertaken. Namakwa Sands has been rehabilitating mined out areas as the mining front moves forward. Due to the difficulty of rehabilitating mined out areas as a result of harsh environmental factors, Namakwa Sands has initiated various research projects to gain an understanding of the baseline conditions and ecosystem function in order to increase plant cover and biodiversity on post-mined areas. This on-going research and the development of rehabilitation and mining techniques have resulted in the implementation of four rehabilitation techniques varying in investment of topsoil replacement, seeding and plant translocation. This study assesses the success and effectiveness of these techniques in terms of various vegetation and soil parameters. In addition, those parameters that are considered useful for monitoring are identified. This study indicated that topsoil replacement and plant translocation facilitate the return of similarity, species richness, species diversity and vegetation cover to post-mined areas. The rehabilitation site that had the greatest amount of biological input (topsoil replacement and plant translocation) appeared to be the most successful technique in facilitating vegetation recovery similar to reference sites. In comparison, the site that had the least amount of biological input performed the worst and requires adaptive management, e.g. reseeding and / or plant translocation. Namakwa Sands should continue to replace topsoil in all future rehabilitation efforts and, when possible (e.g. after sufficient winter rain), continue to translocate species in multi-species clumps. In terms of species selected for translocation, Othonna cylindrica, Ruschia versicolor and Lampranthus suavissimus should be considered for future large-scale translocation projects. Zygophyllum morgsana appears to be more difficult to re-establish under the current climatic conditions (below average rainfall). The long-term viability of rehabilitated Z. morgsana populations needs to be determined before considering this species for any future large-scale translocation purposes. No translocated Asparagus spp. individuals survived and should therefore not be considered for any further translocation purposes. The grass Ehrharta calycina, which is dominant in the site seeded, should continue to be considered for future seeding. Species and functional diversity appear to be the most limiting factors within all the rehabilitation sites and Namakwa Sands will not be able to meet their long-term objective of small-stock farming if diversity and the number of palatable species do not increase significantly. Adaptive management should seriously be considered in order to speed up this process. Alternatively, an appropriate grazing strategy, which is related to the Tetragonia fruticosa dominated vegetation within rehabilitation sites, would need to be determined and adopted.More time is needed to ameliorate the rehabilitated soil profiles to the same level as in reference sites, especially with regard to carbon, pH and sodium levels. In order to increase organic matter within rehabilitation areas, Namakwa Sands should consider creating clumps with cleared vegetation from the mining front. Since the long-term rehabilitation goal has not been achieved, Namakwa Sands will need to continue to monitor plant and soil changes until it has been achieved. The objectives of the current rehabilitation programme are limited and Namakwa Sands should develop additional objectives relating to the structure and function of the natural vegetation. This will give a better indication of whether rehabilitation sites are progressing towards the desired end point and if adaptive management is required. In addition, the current monitoring programme (vegetation survey) implemented at Namakwa Sands could be improved by increasing the vegetation parameters to be monitored. It is recommended that the following vegetation parameters be monitored as part of the long-term monitoring programme: species composition and similarity, species richness, species diversity, vegetation cover, species dominance, vertical structure and functional diversity of the vegetation (clumps and inter-clumps). It is also recommended that carbon, pH and sodium of soil profiles be monitored as part of the long-term monitoring programme. These parameters should not be seen as exhaustive as this study only considered various vegetation parameters and soil chemistry between rehabilitation and reference sites. The results of other studies on the fauna, mycorrhiza, insects, etc. should also be taken into consideration and the monitoring parameters expanded accordingly.

A mineração promove alterações significativas nos atributos do solo. Freqüentemente o substrato, proveniente de materiais estéreis do processo minerador, serve como meio de crescimento da vegetação das áreas em recuperação ambiental. Um procedimento para monitoramento da qualidade do substrato dessas áreas foi desenvolvido e testado. Os estudos foram conduzidos em uma mina de areia industrial situada no interior do Estado de São Paulo que apresenta cronosseqüência de medidas de restabelecimento de vegetação nativa em bacias de disposição de rejeitos de tratamento de minério, permitindo a simulação do monitoramento por um período de 14 anos. Foram analisadas as mudanças das características físico-químicas do substrato em conjunto com as mudanças na vegetação. Como resultado, verificou-se uma evolução positiva na qualidade do substrato que acompanha o desenvolvimento das espécies implantadas e conclui-se que as variáveis estudadas têm plena possibilidade de atuarem como indicadoras de desempenho da revegetação. Deste conjunto de variáveis, a densidade de solo, os teores de matéria orgânica e fósforo e o pH são os indicadores mais apropriados para avaliar o estado da revegetação, especificamente para as condições do ambiente das bacias de rejeito estudado. As áreas avaliadas encontram-se estabilizadas e contêm uma comunidade vegetal já formada. Contudo, a compactação do substrato, os baixos teores de matéria orgânica e o crescimento invasivo de Brachiaria decumbens (capim braquiária) foram identificados como fatores adversos que dificultam uma melhoria mais contundente na comunidade estabelecida. Concluiu-se que o método proposto constitui um instrumento prático para se obter parâmetros numéricos que permitam uma avaliação quantitativa e objetiva das áreas revegetadas e dos resultados das medidas de recuperação ambiental. Os indicadores podem ser utilizados em conjunto com parâmetros específicos que descrevam o estado da comunidade vegetal. Adicionalmente, podem ter aplicação em minerações de outros bens minerais, particularmente no caso de recuperação ambiental de bacias de disposição de rejeitos.Mining is an agent of significant changes in soil properties. Successful land rehabilitation depends on restoring those characteristics in natural soils or establishing a suitable substratum for plant growth using available materials such as waste rock or mineral tailings. A process for monitoring the quality of the substratum in mine-affected areas was developed and tested. The study was carried out at an industrial sand mine located in São Paulo State, Brazil. Different plots situated in a tailings pond were restored with native species by the company for the past 14 years, allowing for 10+ years of simulated monitoring. Soil samples were collected to measure a series of physical and chemical substratum properties. Indicators of vegetation development were collected in each plot. As a result, a positive quality evolution of the substratum is observed simultaneously with the development of planted trees. In conclusion it was verified that observed substratum variables have ample possibilities to be suitable as revegetation performing indicators. From all substratum variables studied, soil density, organic matter, P contents and pH are the most appropriated indicators, specifically in the environmental conditions of the tailings pond studied. All evaluated areas feature a well established vegetal community. However substratum compaction, low contents of organic matter and intense weed growing (Brachiaria decumbens) were identified as limitative. The proposed method sets up a practical instrument to obtain quantitative parameters that allow for an objective assessment of revegetated areas and environmental rehabilitation actions. The indicators may be applied to other types of mines, specifically in case of tailing disposal sites.

Full textAbstract:
The native plant communities of Canterbury, South Island, New Zealand have been severely modified and degraded and the Canterbury Plain (750,000 ha) retains few remnants of its original forest and other ecosystems. The research presented here considers the mutualistic roles of exotic and indigenous species in the process of restoring degraded landscapes. Exotic species may have an important role in the (re) establishment of desired indigenous species, and may influence succession through to a forest dominated by them. One aspect of this work describes indigenous plant community regeneration facilitated by exotic willow (Salix spp.) woodland on the Canterbury Plain. Natural colonisation of the willow woodland by native plants was investigated, with respect to variation in the physical environment in the willow stand. Key factors in the success of willow woodland as a nursery for regeneration of native vegetation include: distance to the nearest seed source, the ability to attract seed dispersers (recruitment only occurred under perch sites), flooding potential (higher recruitment in areas less likely to flood) and possibly light availability. Control of vertebrate (and invertebrate) herbivory is also necessary for successful restoration. A second aspect was a field experiment in open pasture and in a non-native remnant woodland which was then used to investigate the effects of shelter, plant spacing, mulching and fertiliser on growth and survival of planted native woody species. With minimal management, the selected mid-late successional plants established poorly in the open pasture and had low survival rates (e.g.,Dacrycarpus dacrydioides, Pseudopanax arboreus, Aristotelia serrata, Melicytus ramiflorus). Only narrow-leaved species (e.g., Plagianthus reg ius, Hoheria angustifolia, Hebe salicifolia, Cordyline australis) survived this open pasture planting. In contrast, most species (broad and narrow-leaved) established under the sheltered sites. Exotic nursery vegetation and the establishment of native species, which will, in time, act as a seed source, will be important in successfully restoring a sustainable indigenous element in the cultural landscape of Canterbury. Ecological restoration requires an integrated approach, identifying and understanding the component processes of regeneration, and of the particular aspects/characteristics of the sites involved. This research shows that naturally established plants where existing shelter is available (in this case established willows) tend to have higher growth rates than individually planted plants in open situations, and that the availability of a suitable seed source can also contribute to successful establishment and growth rates. The meeting of restoration targets on the Canterbury Plain may be accelerated, and costs reduced, through the utilisation of areas where exotic species occur (for instance, extensive willow stands in riparian areas adjacent to waterways) and more particularly, where a local seed source is also available. The findings of this research can contribute to restoration management in helping identify the best practices, based on research, that can lead to the restoration of original plant and animal communities.

[Truncated abstract. Please see the pdf format for the complete text. Also, formulae and special characters can only be approximated here. Please see the pdf version for an accurate reproduction.] This thesis examines the water use, ecophysiology and hydraulic architecture of Eucalyptus marginata (jarrah) growing on bauxite mine rehabilitation sites in the jarrah forest of south-western Australia. The principal objective was to characterise the key environment and plant-based influences on tree water use, and to better understand the dynamics of water use over a range of spatial and temporal scales in this drought-prone ecosystem. A novel sap flow measurement system (based on the use of the heat pulse method) was developed so that a large number of trees could be monitored concurrently in the field. A validation experiment using potted jarrah saplings showed that rates of sap flow (transpiration) obtained using this system agreed with those obtained gravimetrically. Notably, diurnal patterns of transpiration were measured accurately and with precision using the newly developed heat ratio method. Field studies showed that water stress and water use by jarrah saplings on rehabilitation sites were strongly seasonal: being greatest in summer when it was warm and dry, and least in winter when it was cool and wet. At different times, water use was influenced by soil water availability, vapour pressure deficit (VPD) and plant hydraulic conductance. In some areas, there was evidence of a rapid decline in transpiration in response to dry soil conditions. At the end of summer, most saplings on rehabilitation sites were not water stressed, whereas water status in the forest was poor for small saplings but improved with increasing size. It has been recognised that mature jarrah trees avoid drought by having deep root systems, however, it appears that saplings on rehabilitation sites may have not yet developed functional deep roots, and as such, they may be heavily reliant on moisture stored in surface soil horizons. Simple predictive models of tree water use revealed that stand water use was 74 % of annual rainfall at a high density (leaf area index, LAI = 3.1), high rainfall (1200 mm yr-1) site, and 12 % of rainfall at a low density (LAI = 0.4), low rainfall (600 mm yr-1) site, and that water use increased with stand growth. A controlled field experiment confirmed that: (1) sapling transpiration was restricted as root-zone water availability declined, irrespective of VPD; (2) transpiration was correlated with VPD when water was abundant; and (3) transpiration was limited by soil-to-leaf hydraulic conductance when water was abundant and VPD was high (> 2 kPa). Specifically, transpiration was regulated by stomatal conductance. Large stomatal apertures could sustain high transpiration rates, but stomata were sensitive to hydraulic perturbations caused by soil water deficits and/or high evaporative demand. No other physiological mechanisms conferred immediate resistance to drought. Empirical observations were agreeably linked with a current theory suggesting that stomata regulate transpiration and plant water potential in order to prevent hydraulic dysfunction following a reduction in soil-to-leaf hydraulic conductance. Moreover, it was clear that plant hydraulic capacity determined the pattern and extent of stomatal regulation. Differences in hydraulic capacity across a gradient in water availability were a reflection of differences in root-to-leaf hydraulic conductance, and were possibly related to differences in xylem structure. Saplings on rehabilitation sites had greater hydraulic conductance (by 50 %) and greater leaf-specific rates of transpiration at the high rainfall site (1.5 kg m-2 day1) than at the low rainfall site (0.8 kg m-2 day1) under near optimal conditions. Also, rehabilitation-grown saplings had significantly greater leaf area, leaf area to sapwood area ratios and hydraulic conductance (by 30-50 %) compared to forest-grown saplings, a strong indication that soils in rehabilitation sites contained more water than soils in the forest. Results suggested that: (1) the hydraulic structure and function of saplings growing under the same climatic conditions was determined by soil water availability; (2) drought reduced stomatal conductance and transpiration by reducing whole-tree hydraulic conductance; and (3) saplings growing on open rehabilitation sites utilised more abundant water, light and nutrients than saplings growing in the forest understorey. These findings support a paradigm that trees evolve hydraulic equipment and physiological characteristics suited to the most efficient use of water from a particular spatial and temporal niche in the soil environment.

Full textAbstract:
[Truncated abstract] Establishment of vegetation and ecosystem functioning is central to the mitigation of environmental impacts associated with mining operations. This study investigated the ecophysiological functioning of mature plants in natural vegetation and applied this knowledge to diagnose problems affecting plant health and causes of poor plant cover at a mine-rehabilitation site. Ecophysiological parameters, including plant water relations and mineral nutrition, were studied in conjunction with soil physical, hydraulic and chemical properties. The natural ecosystem at the study location in the Great Sandy Desert is characterised by sand dunes and interdunes with distinct plant communities on each. One of the most notable features of the vegetation is the presence of large Corymbia chippendalei trees high on the dunes and relatively small scattered shrubs in the interdunes. Triodia grasses (spinifex), dominate the vegetation in both habitats but different species occur in each; T. schinzii is restricted entirely to the dunes, and T. basedowii occurs only in the interdunes. It was hypothesised that the deep sandy dunes afford greater water availability but lower nutrient supply to plants in this habitat compared with those occurring in the lower landscape position of the interdunes. Water-relations parameters (leaf water potentials, stomatal conductance, d13C) revealed that dune plants, particularly woody species, displayed higher water status and water use than closely related and often congeneric plants in the interdunes. Nutrient concentrations in soils were significantly higher in the interdunes, but concentrations in foliage were similar for related species between habitats. It is concluded that the dunes provide a greater store of accessible water than the soil profile in the interdunes. ... Following an experimental wetting pulse equivalent to a summer cyclone event, A. ancistrocarpa plants displayed significant increases in stomatal conductance, leaf water potential and sap velocity in lateral roots within three days of irrigation at the natural site and two days at the rehabilitation site. Secondary sinker roots originating from distal sections of lateral roots were evidently supplying water to maintain hydraulic function in laterals, thus enabling a fast pulse response. This was accentuated at the rehabilitation site where roots were confined closer to the surface. These results indicate that plants at the rehabilitation site are more dependent on small pulses of water and have less access to deep reserves than plants at the natural site. It is concluded that high runoff losses and insufficient soil depth are major factors contributing to plant water stress, and combined with the direct impacts of erosion, are largely responsible for plant death and ultimately poor plant cover. These issues can be alleviated if cover soil depth is increased to more than 0.5 m and slope angles are reduced to <12o. This study demonstrates the value of an ecophysiological approach for diagnosing problems affecting plant establishment at mine-rehabilitation sites. Furthermore, it has provided recommendations that will improve the rehabilitation strategy and lead to the development of a well vegetated, resilient ecosystem on a stable and non-polluting land form.

Full textAbstract:
The term “Additive Manufacturing” is described as the layered production of parts from a 3D file. Over the past century, this technology has evolved from a complement tool for conventional product development into an independent production method. Whereas high technology industries such as aerospace and medicine were already embraced additive manufacturing, structural engineering and architecture are lagging. Additive manufacturing has the potential to revolutionize the construction and restoration of historic buildings, with foreseeable benefits including highly complex and efficient structures with the reduction in material use and wastage, streamlining and expedition of the design-build process, improved customization. However, there are also challenges and demands: a new way of thinking for design and verifications for stability and serviceability of printed elements, the cost, the need for well-educated engineers.
In this dissertation, the current state of additive manufacturing in construction and historic building restoration/rehabilitation is reviewed as a combination of qualitative and quantitative-based studies. The research aims to give confidence to additive manufacturing applicability in these fields and stimulate further research. The opportunities and challenges are discussed by analysing concrete, polymer, and metal-based processes and their applications of additive manufacturing in the construction sector. A review of structural and non-structural applications in restoration projects, possible future applications in terms of structural strengthening are analysed and opportunities and challenges are identified and discussed. Based on the literature review and experimental lab tests, the outcome was obtained as the tensile mechanical properties are adequate for structural engineering applications. However, further interdisciplinary research on additive manufacturing is necessary to build confidence in structural engineers and architects.

There has been a widespread assessment of the capacity of grasslands to restore after several forms of disturbance. In South Africa forestry is a significant habitat disturbance within the Eastern Highveld grasslands where this study was conducted. The study compared ant communities between disturbed grasslands that have been rehabilitated after pine forestry and undisturbed grasslands. Ant sampling was conducted using pitfall traps within rehabilitated sites of age 10 years to 40 years and undisturbed grassland sites. We expected that exposure to pine plantations would result in remarkable differences in ant species richness, assemblages and abundance. A total of 17 genera and 31 morphospecies were collected; 25 species within the rehabilitated and 22 species from the undisturbed grasslands. The sites did not show any significant differences in their species richness, although they had distinctive species assemblages. Ant diversity showed recovery with increasing age after pine with older sites (38 years and 40 years) showing higher diversity compared to the younger sites especially the 10 year old site.

Full textAbstract:
An economic valuation methodology was developed in order to monetarily quantify the benefits resulting from the Indian River Lagoon - South (IRLS) $995 million Everglades restoration project. Service flows of the IRLS were identified and their associated economic baseline values were estimated utilizing existing research. A water quality baseline for the IRLS was also established and compared with the best available standards. Benefits accruing beyond the baseline values given the completion of the IRLS restoration were estimated via benefit transfer to be approximately $159 million annually, importantly factoring in the established IRLS water quality baseline.
Given these benefit results of a lower bound estimate, the project was determined not to be economically feasible, i.e., NPV < $0, via a cost-benefit analysis. However, Monte Carlo analyses provided further insights into the probability of an economically feasible restoration (36%) given the uncertainty surrounding the benefit estimation, as well as specific variables to focus on to improve this probability. This research highlights the potential significant economic value of the IRLS and the importance of properly estimating this value given the magnitude of costs.

Full textAbstract:
[Truncated abstract] Recovery of soil nutrients, microbial populations and carbon (C) and nitrogen (N) cycling processes are critical to the success of rehabilitation following major ecosystem disturbance. Bauxite mining represents a major ecosystem disturbance to the jarrah (Eucalyptus marginata) forest in the south-west of Western Australia. Mining has created a mosaic of mined areas in various stages of succession surrounded by non-mined forest areas. Initial site preparations within rehabilitation areas such as contour ripping alter soil structure (creation of mound and furrows) and over time also influence the distribution of vegetation and litter. Current performance criteria developed by industry, government and other stakeholders have determined that before post-bauxite mined areas of jarrah forest can be integrated back into normal forest management practises they should be functional and demonstrate resilience to normal forest disturbances such as fire. Furthermore, resilience should be of a manner comparable to non-mined analogue forest sites. Currently little is known of the resilience of microbial communities and C and N cycling in rehabilitation sites to normal forest disturbances such as prescription burning. As such, before rehabilitated jarrah forests can be successfully integrated into broad scale forest management regimes, a more thorough knowledge of the potential impacts of burning practises on the soil microbial community and C and N cycling processes in these systems is required. ... While there are similar rates of C and N cycling the underlying microbial community structure was distinctly different; implying a high degree of functional redundancy with respect to C and N cycling. Differences in the C and N cycling and structure of the microbial communities were likely to be due to differences in soil environmental conditions (i.e. soil alkalinity/acidity, soil moisture) and C substrate availability which influence the physiological status of the microbial community and in turn are related to successional age of the forests. Results also suggest that the measurement of CLPP can be a useful approach for assessment of changes in the functional ability of microbial communities. However, the interpretation of how well these rehabilitation forests have recovered heterotrophic abilities was greatly affected by the methodological approach used (e.g. MicroRespTM or Degens and Harris, 1997). Importantly, results from Chapter 4 and 5 suggested that the effects of a moderate prescription fire on C and N processes, CLPP and microbial community structure of 18 year old rehabilitation forests are likely to be short-lived (< 2 years). Furthermore, the effects of the moderate spring prescription fire were not large enough to decouple C and N cycling processes over the short-term (< 1 years) which suggests that by 18 years of age rehabilitation forests demonstrate comparable functional resilience to a moderate prescription burn.

Ecological restoration has yet to gain an indepth understanding of the social dynamics that inform restoration design and enable improved watershed performance in urban environments. The Rio Salado Environmental Restoration Project is unique in that the scale of the project expands to new reaches of the Salt River with each successful venture. The 40-year project has been most successful in recent years due to innovative strategies that capitalize on public outreach and inclusion. Adoption of multi-purpose objectives that include partnerships, public stakeholders, and learning achievement have contributed to the project's success. The ability of the restored system to withstand flood events is one of the many examples demonstrating the project's qualifications as a model for future urban restoration efforts. Lessons about the social dynamics that inform urban restoration success have the potential to augment scientific learning in ecological restoration.

Full textAbstract:
Loss of speech is one important factor which contributes to a decrease of life quality for patients who undergo larynx removal following for example advanced laryngeal cancer. Several devices such as the electrolarynx and the tracheo-esophageal valve prosthesis (without oscillation) have been commercialized in order to restore speech. However, such voice restoration prosthesis are still limited for certain patients. The development of a new device using a valve of variable resistance entrained by a linear electromechanical transducer was investigated as a way to produce speech for patients with total laryngectomy (ablation of vocal folds). The concept was to undertake the design of a varying air flow resistance valve, built around existing Blom-Singer valves. The oscillating valve features a spherical head making it possible to block the opening in the wall between the trachea and the esophagus in a sinusoidal periodic fashion. A physical model of the vocal tract was built and used for preliminary in-vitro verification studies. The relationship between pressure and flow rate through the valve was determined from pressure measurements. The orifice discharge coefficient of the orifice was then calculated and the parameters of a variable resistor model were identified. Radiated sound pressure produced from the change in flow rate at the valve orifice was then compared to the original voice output to assess the accuracy of the design prototype. Results showed that the forced oscillating valve prosthesis model has lower power efficiency but can produce better sound quality than the electrolarynx.

Bibliography: leaves 86-92.Quarry operations are only a temporary use of the land, while the environmental impacts associated with them are more long term. For this reason, it is unacceptable to merely abandon a quarry once operations have ceased. This study considers the role of rehabilitation in providing solutions for the disturbances caused by quarrying. The value of adopting a pre-planning approach towards rehabilitation is considered, and the components of a rehabilitation programme are identified. Using this information a rehabilitation checklist is drawn up. A survey of thirty rehabilitation reports, submitted to the Cape Town regional offices of the Department of Mineral and Energy Affairs, was undertaken using the checklist. Results of this survey indicate that rehabilitation reports are submitted merely to meet the minimum legal requirements contained in the Minerals Act of 1991 (Act No 50 of 1991). This study recommends that successful rehabilitation will only be achieved when rehabilitation reports function as effective working documents.

The Atchafalaya River is a 135-mile long river in Louisiana. This makes it the largest distributary of the Mississippi. In this thesis, I will review the ways in which the Atchafalaya Basin is described as a complex system by the two agencies that are responsible for its management, the US Army Corps of Engineers and the Louisiana Department of Natural Resources. Different stakeholders understand the Basin in a variety of ways. My question is how the different views of the Basin impact its environmental restoration and management. I answer this question by describing how the agencies transform elements of the Basin into maps, plans and various management activities by relying on science, aerial photography, and long-time residents of the Basin. I will argue that a central aspect of successful environmental restoration is that communication among different stakeholders must create a shared discourse to frame the main issues in the Basin. In the Atchafalaya Basin, this means that environmental restoration cannot be successful without some level of consensus among the stakeholders about what the Atchafalaya Basin is, how it has developed and which environmental qualities are present in the Basin today and which ones need to be restored.

Full textAbstract:
This thesis investigated the restoration of mauri (life-force) to Ōkahu Bay, Auckland New Zealand. Ōkahu Bay is part of the land and waters of Ngāti Whātua Ōrākei, a Māori hapū (sub-tribe). Ngāti Whātua Ōrākei has been driving the restoration, restoring Ōkahu Bay based on their worldview, visions, and concerns. This vision and control of the restoration process allows them to bring in the hapū in sustainable engagement and have the long-term vision and commitment necessary for self-determination. However, while there has been progress with projects and improved decision-making authority, hapū members are still not seeing their whānau (family) swimming in and caring for Ōkahu as much as they would like. Interviewees wanted to see an explicit focus on encouraging hapū members to use the bay, such as more educational programs and water-based activities, and continued efforts to improve water quality. Shellfish populations have also not recovered after a decade of monitoring due to structural aspects such as existing stormwater pipes. Changing these requires Auckland City Council to make stronger commitments to supporting Ngāti Whātua’s restoration. Overall, this investigation showed that in this restoration, a clean environment is essential to build community and a community is essential to build a clean environment. This community-driven restoration, while not perfect, has great potential to truly reconnect people with their environments, decolonize the land and the people, and create thriving ecosystems and people that benefit themselves, their communities, and the wider Auckland community.

Full textAbstract:
Rehabilitation hospitals serve to foster a client’s independence in preparation to return home after an injury or insult. Having space in rehabilitation environments that is home-like and supportive for each client can facilitate participation in occupations and assist in learning and practicing the skills needed to transition to home. Yet, typically occupational therapists provide interventions to clients in therapy gyms with exercise and impairment based equipment. Currently the stroke population is changing and identifying the optimal rehabilitation environment is imperative to guide occupational therapy practice. This dissertation contains three studies relating to the rehabilitation environment and occupational therapy interventions. The first study focused on the perceptions of occupational therapists regarding their optimal rehabilitation environment, identifying that they would prefer to offer their clients a variety of rehabilitation environments and that there is a relationship between the environment and the type of intervention provided. A second study examined the effects of occupation-based interventions provided in a home-like environment to an individual recovering from chronic stroke with the results indicating enhanced occupational performance, resumed competence in desired roles, improvement in affected upper extremity function, and notable neuroplastic change. The final study investigated how the rehabilitation environment influenced the interventions used by the occupational therapists. The findings supported the relationship between the therapy environment and a specific intervention; working in the therapy gym with preparatory methods and being in a home-like space using occupation-based interventions. The environment influenced occupational therapy interventions and it is recommended that the occupational therapist match the client’s goals to the ideal environment for optimal intervention.

Full textAbstract:
The work presented in this thesis was performed firstly to highlight the changes wrought in restored soil systems following the disruptive activities of opencast coal mining, and thereafter to identify, simulate and assess the effects of some typical perturbations associated with these activities. The microbial community was used as a focus for these investigations and the methods of soil adenosine 5'- triphosphate content analysis, dehydrogenase activity analysis and ergosterol content analysis were utilised alongside several other physical and chemical determinations. A field study of restored sites of various ages after cessation of opencast coal mining was undertaken which reinforced the utility of the microbial measurements. Experimentation was performed to investigate the effects of soil storage (at two depths), physical disturbance, compaction and the effects of the different combinations of these perturbations. Novel findings were obtained largely due to the paucity of research addressing the controlled manipulation and careful interpretation of these individual perturbations, and their effects when combined. The storage of soil was found to be the dominant factor influencing the status of the microbial communities upon restoration, and also influencing the development of these communities and the emergent plant biomass, post-restoration. This study found that soil, reinstated after opencast coal mining, becomes quickly dominated by fungi and, under grassland management, this domination then subsides over many years to a more bacterialcharacterised system. Differences were identified between the action of physical disturbance and compaction on stored and unstored soils. The deleterious effect of physical disturbance on unstored soil and the apparent ameliorative effect on soil affected by opencast operations can be interpreted through the change in soil architecture engendered by this treatment. The severe disturbances associated with opencast coal mining were found to affect the soil biota, primarily in terms of enduring environmental change. Thus the study of soil ecology was used as a sensitive indicator of recovery of disturbed land, and the changing energy flow through detrital food-webs was used as a model to follow this recovery process.

As the Americans have become more aware of the impact to the environment from the human induced disturbances which includes physical, chemical and biological disturbances to the degradation of streams and rivers, many studies and experiments have been done in an attempt to restore streams and rivers to more natural conditions. At the same time, success in public education and community involvement has encouraged grass-root movements that engage people in stream restoration efforts.
Stroubles Creek is a freshwater stream located in Blacksburg, Virginia. The creek has experienced considerable disturbance due to land use changes over the past 100 years. The Stroubles Creek Water Initiative (SCWI), originated by the Virginia Water Resources Research Center at Virginia Tech, has been monitoring the creek for a number of years. This paper develops a planning framework for restoring and/or rehabilitating Stroubles Creek within the Town of Blacksburg. The results of stream monitoring and other research by SCWI are used to inform the recommended planning process, while a literature review and discussion of “urban stream restoration case studies” are used to guide future decision-making related to Stroubles Creek restoration/rehabilitation.Master of Urban and Regional Planning

Full textAbstract:
The development of emergency department medical interventions and the implementation of fast-transport trauma systems has decreased the rate of death resulting from traumatic brain injury (TBI). Without corresponding methods for long-term treatment and recovery, the prevalence of people disabled by TBI has increased, creating a growing public health problem. Investigations generated by physicians, rehabilitation programs, and social scientists, which attempt to associate standard measures of injury severity with outcome, leave unexplained variance in long-term functional status for persons with TBI.
The purpose of this investigation was to use persons with brain injury and their family members, to guide an analysis of the factors that foster successful recovery from brain injury. Three studies were conducted. In Study #1, the method for observation generated by Kurt Goldstein (1934) was adopted to conduct 20 case studies of persons who sustained brain injury. The Schema of the EsEx Couple (Maynard. 1992) was used to orient the investigation. The EsEx Couple Schema proposes that events in human life must be understood by considering the whole system of Person (Essence) in the Environment (Exchange), and the transactions that flow in a recursive loop from Person to Environment and back. Kurt Goldstein's Laws of Organismic Life (1934), a model consistent with that of the EsEx Couple, was used to evaluate the data. Strong patterns associated family and social networks, autonomy, and perceived self-determination with higher levels of recovery, and were used to generate a Model for Recovery.
In Study #2. the Motivational Analysis of Self-Systems Processes (Connell & Wellborn, 1991) was combined with results from Study #1 to generate a Development Model, and to build a survey which was administered to 248 persons with brain injury. Results (1) confirmed the model, indicating factors that contribute to recovery were hypothesized measures of Social Context, Perception, and Engagement; and (2) established a valid instrument, generated by persons with brain injury and their families, for measuring functional status.
In Study #3. results of the survey research were used to return to the case studies to consider where individual lives differ from expected patterns, and why. Deviations from expected patterns were explored to identify how individual differences operate to affect outcome. Recommendations for clinical practice include (1) directing interventions toward family as well as patient, as a method of enhancing the Social Context for the patient, and (2) using careful evaluation of each patient's idiosyncrasies to consider individual interventions.

The context in which we find ourselves at the beginning of the twenty-first century is one of acute environmental degradation. In this thesis, I examine how Christians may respond to the realities of degradation through ecological restoration, an environmental practice aimed at assisting the recovery of ecosystems that have been degraded, damaged, or destroyed, and do so in ways that reflect the core belief in the redemptive purposes of God in Christ for creation. The intention, therefore, is to construct a theological framework for ethical responses to degradation through restoration. I begin by examining ecological restoration as a contested scientific and cultural practice, exploring the questions it raises on the nature of human life, the natural world, and moral action, and evaluating the role of history in shaping moral responses to degradation through restoration. To develop a theological framework for restoration, I engage the work of Christian ethicist Oliver O'Donovan, particularly his text on the foundations of Christian ethics: Resurrection and Moral Order. I ground this framework in his arguments for the resurrection (with its dual movements of restoration and transformation) as the starting point for moral action, for the work of the Holy Spirit who makes God’s redemption a reality that shapes moral action, and for love as the shape of moral action. I draw out the significance for restoration of his moral realist approach, examining the created order and articulating a theological anthropology, and I show how the resurrection of Christ provides a guide for restorative action that both affirms the created order and yet remains attentive and open to its, and our, transformation. Finally, through an examination of love as perceptive and responsive to the natural world, I articulate a vision for restorative action that is oriented toward upholding and preserving the value of the natural world, and attentively and creatively responding to it in ways that bring forth its value so that it may be seen for what it is: the beloved world that God has affirmed and redeemed in the resurrection and which awaits its fulfilment.

This thesis presents recommendations for controlling quality in structural interventions on historic properties. Recognizing that establishing quality in the early stages of an intervention can set the standard of quality for an entire project, these recommendations are for the first phase of an intervention, the Pre-Construction Phase. To create these recommendations, first a literature review of past and present intervention methods is conducted. After breaking down the Pre-Construction Phase first into a series of steps, and then each step into a series of details, a standard of quality is established for each detail. The available methods for conducting each detail are then analyzed. Using the literature review and the established standards of quality, recommendations are made as to which method is most appropriate for a given project. These recommendations are applied to two case studies, the structural interventions of Boykinâ s Tavern and Fallingwater. Finally, conclusions on the use of the proposed quality control recommendations are drawn, and suggestions are given for further work in this field.Master of Science

Full textAbstract:
Since the turn of the twentieth century, mining activities have contaminated the floodplain and streambed of Silver Bow Creek, Montana, resulting in a streambed devoid of life and severely contaminated with heavy metals. In the mid nineteen seventies, up-stream water treatment facilities were upgraded and water quality improved, bringing benthic invertebrates back to reaches of Silver Bow Creek. The extent and concentration of toxicants in and around the streams of the Upper Clark Fork River Basin resulted in the designation of over 100 miles of river as Federal Superfund sites. Since 1999 reclamation and restoration efforts have been implemented on Silver Bow Creek. This analysis evaluates changes in benthic biotic community composition throughout the period of record (1986 to 2009). Transformations of historical data were necessary to standardize community information and calculate indices of biotic integrity. A multivariate method, Classification Strength (CS), used in conjunction with non-parametric tests of significance, demonstrated data comparability over the period of record both taxonomically and ecologically. Biotic index results indicate that remedial efforts to remove metals laden sediment from the stream bed and surrounding floodplain have resulted in a decline in the numbers of metal-tolerant organisms. Generalized indices of biotic integrity show no significant changes throughout the period, while specialized indices demonstrate increases in organic-pollutant-tolerant taxa. Multivariate analysis of community composition demonstrates taxonomic changes to the resident community throughout the period of record, and Indicator Species Analysis corroborates the results of the biotic indices. Using these methodologies as a template to measure change throughout the restored reaches of Silver Bow Creek will increase the ability of resource managers to measure the success of restoration of the Last Best Disturbance.

For almost 450 years the island of Puerto Rico has had an agricultural economy based on the cultivation and production of sugar. Sugar plantations became small communities within towns with distinctive structures and buildings. When large scale commercial sugar production ceased, plantation houses were abandoned and have deteriorated to the point of collapse. A small number of plantation houses are still standing in defiance of progress and their own deterioration.Plantation houses represent part of Puerto Rico's economic and social history and deserve to be preserved. As a result of their architectural significance and uncertain future, plantation houses throughout the Island, should be documented.The focus of this Creative Project is the documentation of the main house in La Monserrate sugar plantation and present recommendations for its rehabilitation and adaptive reuse. This plantation house is located in Manati, a town along the north coast of Puerto Rico. The document will cover a variety of subjects all related with the history of the development of the sugar industry and its influence in Puerto Rico's architecture. The document includes both, a comprehensive analysis of the house and preliminary recommendations for its future adaptive reuse.It is the author's hope that this document will increase public awareness about the importance of preserving this particular building as well as some of the cultural and economic advantages of historic preservation. The community needs to understand and appreciate their built heritage and restoring and rehabilitating the main house in Hacienda La Monserrate can be the first step to achieve it.Department of Architecture

Ecological restoration has the potential to stem the tide of habitat loss, fragmentation and transformation that are the main threats to global biological diversity and ecosystem services. Through this thesis, I aimed to evaluate the ecological consequences of a 33 year old rehabilitation programme for coastal dune forest conservation. The mining company Richards Bay Minerals (RBM) initiated what is now the longest running rehabilitation programme in South Africa in 1977. Management of the rehabilitation process is founded upon the principles of ecological succession after ameliorating the mine tailings to accelerate initial colonisation. Many factors may detract from the predictability of the ecological succession. For example, if historical contingency is a reality, then the goal of restoring a particular habitat to its former state may be unattainable as a number of alternative stable states can result from the order by which species establish. Succession appears to be a suitable conceptual basis (at this stage in regeneration at least) for the restoration of coastal dune forest. Patterns of community characteristics observed in rehabilitating coastal dune forest sites were similar to those predicted by ecological succession, with few exceptions. Changes in the species pool such as the establishment of strong dominants may lead to divergence of regenerating trajectories away from the desired endpoints. The species composition of herbaceous plants in regenerating coastal dune forest sites became increasingly uniform as the time since disturbance increased. Despite initially becoming more similar they II deviated away from an undisturbed reference site. Contrary to our expectations, non-native species did not contribute the most to dissimilarity. The deviation from the reference forest is attributable to the higher abundance of a native forest specialist in the reference site and the higher abundances of native woodland adapted species in the rehabilitating sites. Changes in the disturbance regime under which species have evolved may lead to arrested succession. The rehabilitation of coastal dune forest relies on the Acacia karroo successional pathway which, has been criticised because Acacia dominated woodlands may stagnate succession. The patterns of species composition within regenerating coastal dune forest are a response to the canopy characteristics and represent an early stage in forest succession. Succession did not appear to be stagnant. Ecological succession does not pay much heed to the role that the surrounding landscape composition can play in the assembly of communities. The theory of Island biogeography provides predictions about how landscape composition influences community assembly. Landscape spatial parameters, measuring edge, isolation, and area explained the patch occupancy of the several bird and tree species, however, responses to patch characteristics were varied and idiosyncratic. For restoration to succeed, managers need to consider the spatial configuration of the landscape to facilitate colonization of rehabilitating patches. From this thesis and previous work, it appears that processes are in place that will lead to the reassembly of dune forest communities. As the rehabilitating sites are at an early stage of regeneration this may take some time to give rise to these coastal dune forest communities, and the management of rehabilitating coastal dune forest must allow for this. In addition, it is III important to remember that time may be interacting with the landscapes spatial attributes, which may limit the presence of certain species.Thesis (PhD)--University of Pretoria, 2011.
