Résumé :

Root-filled teeth are weakened by loss of strategic tooth structure through restorative procedures and caries, rather than by the endodontic procedures. Therefore, prompt restoration is required to minimise coronal leakage and the risk of tooth fracture. However, restorability should be confirmed before root canal treatment begins, by removing caries and existing restoration to evaluate the residual tooth structure. Based on the remaining tooth structure, the restoration is planned to maximise the longevity of root-filled teeth as a functional unit. This review considers risk factors for survival of root-filled teeth and principles of restoration, rather than detailed techniques, including direct and indirect restorations. Ssummary and conclusions Restorability and the type of definitive restoration should be determined, at least provisionally, before root canal treatment is begun. The restoration is crucial for the long-term survival and function of the root-filled tooth. The choice and design of the restoration should be based on the principles of conservation and protection of remaining tooth structure, which requires some form of cuspal protection for most posterior teeth.

Résumé :

Abstract In general excellent results cannot be guaranteed when using resin-based composites for posterior restorations. This is due to polymerization shrinkage which can still be regarded as the primary negative characteristic of composite resins. A review of available literature regarding the polymerization process, its flaws, and suggested strategies to avoid shrinkage stress was conducted. Several factors responsible for the polymerization process may negatively affect the integrity of the tooth-restoration complex. There is no straightforward way of handlling adhesive restorative materials that can guarantee the reliability of a restoration. At present, the practitioner has to coexist with the problem of polymerization shrinkage and destructive shrinkage stress. However, evolving improvements associated with resin-based composite materials, dental adhesives, filling, and light curing techniques have improved the predictability of such restorations. This critical review paper is meant to be a useful contribution to the recognition and understanding of problems related to polymerization shrinkage and to provide clinicians with the opportunity to improve the quality of composite resin restorations.

Résumé :

With increased dental awareness, there has been a growing trend in patients who are opting for teeth retention, so post-endodontic restorations play a significant role in dictating restoration longevity. However, till date restoration of root canal treated teeth is still controversial. Root canal treated teeth often suffer from extensive loss of tooth structure because of access cavity preparation, caries removal, replacement of restoration and trauma.1 Traditionally the restorative material of choice for an endodontically treated molar would be post and core followed by metal / ceramic crowns. However, studies have shown that these intra-canal posts may increase risk, of undermining the residual tooth structure, root perforation and catastrophic failures.2 With adhesive strategies, there has been a paradigm shift towards post-less restorations and utilisation of pulp chamber as an extension, thus integrating the crown and core as a single unit or monobloc. 2,3 This was the concept of the endocrown technique. 3 Bindle and Mormann first, delineated the use of porcelain adhesive endodontic crowns.4 Endocrowns are more practical, conservative, aesthetic, simple to fabricate, economical, less time consuming and allows favourable distribution of masticatory stresses. Most studies on endocrowns showed comparable or somewhat superior results to other conventional treatments for endodontically treated teeth (ETT). However, the available literature is based largely on the use of ceramic endocrowns. 2-4 It was observed that data pertaining to endocrown fabrication with other indirect restorative materials is still limited, and the choice is still unclear.Indirect composites show enhanced mechanical properties, creation of ideal contacts and contours, favourable wear, aesthetics and can serve as an economical alternative to ceramics.5 Hence, this paper attempts to present a case report of functional and aesthetic rehabilitation of an endodontically treated molar with an endocrown restoration utilising indirect composite (SR Adoro System).

Résumé :

This paper illustrates the relation between resilience and water system serviceability, and the dependence of community resilience on water system resilience. Five normally provided water system service categories are defined: water delivery, quality, quantity, fire protection, and functionality. Water system performances are described in terms of how these services are provided to customers after an earthquake in relation to pre-earthquake services. The important distinction between system operability and functionality is defined. The characteristics of each service restoration and how they interact are explained. A case study from the Los Angeles Water System is presented to show applicability of the five service categories in actual post-earthquake restorations. The examined service restoration features can be used as engineering and management principles to improve overall service restoration. Some strategies for improving post-earthquake services and their restorations are presented in the context of the five service categories. Reviewing the five water service categories identifies how water system resilience is more complex than previously recognized.

Résumé :

This article provides an overview of current knowledge and understanding of existing criteria for the assessment of dental restorations and encourages dental practitioners to shift, if not already doing so, to considering minimally invasive interventions for manging deteriorating restorations. The repair of restorations in such a way extends longevity of the restoration without sacrificing intact, healthy tooth tissue, and is in the best interest of patients in terms of biological and economic costs. The replacement of a restoration should be only considered as a last resort, when there are no other viable alternatives. CPD/Clinical Relevance: Standardised assessment of dental restorations, using established criteria for clinical judgement and decision-making, is particularly important when managing deteriorating restorations in clinical practice. Minimally invasive management of such restorations, in terms of restoration repair strategies, should be viewed as a safe, viable and effective alternative to other more invasive treatments. The reader should understand the clinical evaluation of dental restorations based on reported standardised parameters and appreciate the benefits of minimally invasive management of deteriorating, yet serviceable, dental restorations in clinical practice.

Résumé :

The esthetic procedures with composites are widely applied, both to posterior and anterior teeth to restore caries cavities, to replace failed restorations, or to make cosmetic procedures. The materials selected to each case may make the difference in the clinical result. This paper presents two clinical cases made with a nanofilled composite resin system used in different bond strategies. In the first, a wide posterior class I restoration, the self-etching strategy was used. The second, an esthetic anterior restoration, was made using the prior etching with phosphoric acid and a hydrophobic adhesive.

Résumé :

A novel procedure for symmetric and consistent layer thickness management in esthetic direct restoration of anterior teeth is presented. For the purpose of obtaining a satisfactory final outcome of an esthetic direct restoration, it is crucial to standardize either margin preparation design and dentin and enamel layer thickness. Leaving too much space for the final translucent layer may lead in fact to “low value—gray” restorations if not correctly managed. The most common tool used to check layer thickness is the sagittal silicone index, which is reliable but involves planning; therefore, it requires two stages appointments. In this clinical case, a novel procedure is used to prepare, to model and to check thickness of composite shades in a single appointment, thus providing a symmetric esthetic outcome. A healthy 21-year-old woman referred to our dental office for the esthetic rehabilitation of both maxillary central incisors. The correct composite bilateral and symmetric layer thickness management provided a predictable esthetic outcome of the restorations. The main objective of this case presentation is to describe a novel technique that is able to save chair-time and dental laboratory costs during direct restorations in anterior teeth.

Résumé :

Background: The use of general anesthesia (GA) among children has seen an increase globally. Both tooth extraction and restoration treatments on children were done under GA, but there are consequences in using GA in children, which also include changes in the treatment plan. First permanent molar (FPM) treatment under GA is a very strategic treatment, but there is a notable lack of studies that assess in detail this type of treatment, especially its frequency of administration under GA. This study determines the treatment frequency and the type of FPM treatment in children under GA at the King Abdulaziz Medical City (KAMC) in Jeddah, Saudi Arabia. Methods: Our study is a cross-sectional study that reviewed the cases of dental rehabilitation in children between the ages of 5 and 14 years old from 2015 to 2018. These children had erupted first permanent molars and were treated under GA. Results: This study included 394 children, with 1330 FPMs treated under general anesthesia for (27%) preventive, (56%) restorative, and (17%) extraction treatments. The frequency of FPM treatments administered were color restoration (49%), fissure sealant application (37%), SSC (8.9%), and amalgam filling (4.5%). Low pulpal treatment was reported which was mostly involved indirect pulp capping. Most of the final restorations that were done covered only one surface, followed by the two-surface restorations, and then by SSC. Conclusions: The pediatric dentists’ decision for FPMs treatment under general anesthesia at KAMC was following AAPD guideline and its frequency was mostly restorative followed by preventive, and the least treatment was extraction treatments. The type of FPMs treatment administered on children was significantly influenced by their ages, gender, and health conditions. The type of tooth restoration and pulp therapy treatments were significantly dependent on children’s age. KAMC pediatric dentist efforts should be directed to initiate more preventive programs and effective dental home care utilization at PHC centers.

Résumé :

Purpose: To examine current decision-making preferences of Jordanian dentists when Restoring Root Filled Teeth (RFT). Materials and Methods: 834 Jordanian general dentists, prosthodontists and endodontists were invited to participate in a validated online survey with a 62% participation rate. Respondents were invited to answer 24 questions about their preferences for techniques and materials they use to restore RFT. The questions aimed at exploring restorative strategies commonly employed by Jordanian dentists when managing root filled teeth with extensive loss of tooth structure. Results: A minority of dentists consider direct resin restoration as the sole restoration for RFT with extensive loss of tooth structure. Full coverage metal-ceramic and all-ceramic crowns are more popular than endocrowns when restoring RFT with indirect restoration. Fiber posts are the most popular type of posts, followed by prefabricated metal posts. Glass ionomer is the most preferred cement for luting metal posts, while conventional dual resin cement with separate etch and rinse bonding strategy is the most employed when bonding fiber posts. The majority of dentists tend not to pretreat fiber posts. Loss of post/core retention or fracture of coronal tooth structure are the two most common reasons observed by dentists when RFT fail. Conclusion: Use of post and core is still preferred over more conservative approaches when restoring RFT with extensive loss of coronal tooth structure. Longevity of restorations can be enhanced by training practicing dentists on evidence-based adhesive strategies.

Résumé :

Aim. The purpose of this in vitro study was to evaluate microleakage of two different adhesive systems: self-etch and etch-and-rinse, using the optic microscopy. Materials and methods. Six sound upper premolar teeth had MOD cavities prepared. The teeth were divided into two groups of three teeth each and two restorative systems were used: 1) Filtek™ Silorane/Silorane System Adhesive (3M ESPE); 2) Premise™ Packable /OptiBond FL (KERR). All restorative materials were placed following manufacturers’ recommendations. After restoring them, the teeth were stored for 5 years in an oven in distilled water at 37°C. Before the tests, the apex was sealed with wax and the teeth were covered with nail polish except 1 mm around the edge restorations. Then, they were immersed in 0.5% alkaline solution of fuchsin for 24 hours. After sectioning, the microleakage evaluation at enamel margin was made using an optical microscope Olympus KCX41 (Olympus America Inc.) at a magnification of 4x and 10x, the method of granting a semiquantitative score of dye penetration on a scale from 0-3. Data were statistically analyzed using Kruskal-Wallis test. Results, conclusions. Microleakage was present in both groups, scores 2 (infiltration dye the entire length threshold cervical enamel) and 3 (infiltration threshold cervical enamel and expanding axial wall towards the pulp chamber), registering only in the Filtek Silorane (FS) group who applied to Silorane system, adhesive Self-etch adhesive system. The most effective adhesive system to reduce the microleakage at marginal threshold cervical MOD restorations on enamel, was etch-and-rinse system, OptiBond FL.

Résumé :

The human presence and activities affect the environmental quality of water bodies in different ways. Pressures concern various aspects of the overall environmental quality and their effects are cumulative and synergic. That’s why an integrated approach is needed to understand and assess the importance of each kind of stressors and to define restoration strategies. The research work carried out in the last three years and shown in this thesis concerns impaired river ecosystems and includes, in particular: 1) Integrated study of chemical, hydrological and biological aspects of impaired rivers, especially those affected by multiple alterations in urban environments and, thus, wastewater treatment plant effluent dominated. A case study (Lura stream) is presented. 2) Development of analytical methods for determining organic micropollutants (PAHs, triazines and their main transformation products) in a wide range of surface and wastewater samples (coming from different environments in Italy and Spain) and, consequently, for evaluating the contamination from wastewater treatment plant discharges. 3) Evaluation of the organic micropollutant removal efficiencies of wastewater treatment plants and comparison of the concentrations measured in effluent samples to the environmental quality objectives fixed for surface waters, as most of the receptor flow is made by the discharged effluent itself. 4) Study of the performance of a demonstration scale constructed wetland in removing inorganic and organic contamination from wastewater treatment plant effluents, as a possible strategy for impaired river restoration.

Résumé :

This thesis proposes new algorithms for restoration strategies that provision bandwidth guaranteed recovery for unicast and multicast connections. The primary focus is on online restoration strategies that sequentially do pre-planning of resource for each request using the current network resource state. Online restoration strategies do not require prior knowledge of all the requests like that of offline restoration strategies. Therefore, online restoration strategies are more suitable for on-demand and dynamic traffic engineering control. The proposed new algorithms are compared to known algorithms from literature. Most literature evaluates the performance of the algorithms with two metrics only: total bandwidth requirement and the number of requests accepted in the network. This thesis evaluates the algorithms in one additional dimension: the computational time. This is an important criterion when response times for establishing new connections are stringent. Each algorithm makes trade-off between computational complexity, bandwidth efficiency, and number of accepted requests. Results show that the proposed algorithms provide alternative trade-offs between the three performance metrics when compared to other existing algorithms. The alternatives provide more choice for the network providers and the best algorithm to use depends on the network's requirements. The restoration strategies used for unicast and multicast connections in this thesis are very compatible thus it is possible to integrate the restoration strategies into a single system where they share the same backup resources. Results from simulations show that using an integrated restoration model has significant benefits, which includes lower backup bandwidth requirement than the separate restoration model.

Résumé :

Libertines’ behaviour does not go unnoticed at Charles II’s licentious court. Social figures of the Restoration age, libertines have a strong Hobbist sense of self-preservation which mingles with an inclination towards the pleasures of life, yet, the inability to find a compromise with society causes their social failure. However, the theatrical dimension seems the only one where libertines, as comic characters, can freely perform their credos. The purpose of this study is to offer a metatheatrical reading of libertine characters drawing on some metatheatrical concerns. The libertine’s conscious appropriation of the genre’s tools unmasks, beneath the fictional stage, a real society made of excesses and creates, in a process which often involves the audience, an alternative theatrical reality. Firstly, the character will be analysed on a plot-level in the roles of the ‘trickster’ and the ‘director’. Secondly, the character’s performative use of language and his overpowering wit shows him mastering language with an awareness alien to the other characters. The final chapter explores the idea of dramatic irony in the aged-old metaphor of theatrum mundi through phenomenological lenses. The study will consider the forty-year period from 1660 to 1700, in particular, selected comedies of Dryden, Etherege, Wycherley, Behn and Congreve will be used to provide examples of the aforementioned concepts.

Résumé :

Land areas being used unsustainably are depleted and/or degraded. To prevent this from happening and/or to reverse the effects, we need to restore these environments. However, not all restoration practices are equal, and some do not adhere to rigorous standards of sustainability. In this study, restoration guidelines and opinions from field experts were analysed from an SSD perspective. The focus of this thesis was limestone quarries in northern Europe due to quarries’ impacts to the socio-ecological system and the sensitivity of northern ecosystems. The results were divided into two sub-sections: FSSD comparison to guidelines, which included an SP analysis to principles in guidelines, and interviews. The conclusion was that the SSD approach could enhance these quarry restoration guidelines by incorporating the recommendations formulated from the results and discussion. One recommendation was having the eight SPs as overarching boundaries for success. Incorporating these recommendations would fill the sustainability gaps, aiding in the practitioner's ability to be strategic and have long-term success within sustainable limits.

Résumé :

Faecal incontinence is a major public health issue that has yet to be adequately addressed. The reported prevalence of postpartum faecal incontinence ranges from 3% to 29%, with obstetric trauma being the most common cause of faecal incontinence. Trauma is often attributed to injury of the anal sphincter muscles. New therapies to restore continence are emerging which combine minimally invasive procedures with restoration of functional sphincter muscle. The aim of the research undertaken in this thesis was to evaluate the use of poly(D,L-lactide-co-glycolide) thermally induced phase separation (TIPS) microspheres for delivery of muscle precursor cells to regenerate injured skeletal muscle. The objectives were as follows: (a) to test the feasibility of attaching muscle precursor cells to the surface of TIPS microspheres; (b) to characterize the phenotypic status of cells attached to the TIPS microspheres; (c) to demonstrate targeted cell delivery using TIPS microspheres; and (d) to investigate the engraftment of cells delivered via TIPS microspheres into host tissue. Major findings of this thesis indicated that the development of a static–dynamic culture technique successfully attached muscle precursor cells to the surface of TIPS microspheres. The technique produced a uniform distribution of cells across the surface of the TIPS microsphere within 24 hours. Cells attached to TIPS microspheres were phenotypically characterized at a gene and protein level. Muscle precursor cells were demonstrated to show an increase in both mRNA and protein expression of cell contractile apparatus. The delivery technique showed no apparent cell membrane damage upon delivery, with substantial cell migration off the TIPS microspheres for delivery in vitro and in vivo. Preliminary findings of an in vivo delivery study showed localized delivery, migration, integration of cells with host tissue, and evidence of myotube formation. The current research supports further study of muscle precursor cells delivered via TIPS microspheres. The concepts developed in this thesis offer a novel approach to regenerating a skeletal muscle tear for obstetric trauma-induced faecal incontinence.

Résumé :

Includes bibliographical references.
Karoo rangelands exhibit spatial and temporal patterns that have important implications for the livestock industry. Spatially, there are gradients, often abrupt, in ecosystem structure and functioning, while plant composition and productivity are highly variable over time. A predictive understanding of these patterns, and the processes that cause them, is a prerequisite for developing appropriate restoration strategies. This thesis comprises several studies that attempt to relate vegetation patterns and processes to restoration strategies in southern Africa's Succulent- and Nama karoo ecosystems. One hypothesis is that small-scale changes in soil physical and chemical properties are responsible for the fine-scale patterning evident in winter-rainfall Succulent karoo ecosystems. Alternatively, these patterns could be the result of area-selective grazing by livestock. To evaluate these hypotheses, plant and soil data were collected along soil- and grazing gradients radiating from a watering point in a Succulent karoo landscape. Results indicated that properties inﬂuencing soil hydrology and nutrient status are important determinants of pattern, and that long-term area-selective grazing can permanently change some of these properties. The hypothesis that the stasis of severely degraded patches in this biosphere is a consequence of poor water inﬁltration and seed limitation was tested in a restoration experiment. It appeared that natural seed availability is not limiting, but water inﬁltration has to be improved to initiate the restoration process. Removal of shrub material in long-ungrazed and moribund areas on the outer perimeter of the biosphere, had a positive impact in releasing resources for more seedlings and young growth, but did not alter plant species richness. Stocking rate, composition and management of livestock profoundly inﬂuence the dynamics and composition of summer-rainfall Nama karoo vegetation. Proponents of non-selective grazing (NSG) argue that the periodic concentration in high densities of livestock in small areas, followed by long resting periods, improves vegetation composition as a consequence of low grazing selectivity, and enhances vegetation productivity and soil ecosystem processes as a result of intense hoof-action, dunging and urination impacts. Despite its application in farming systems, no studies have yet tested the predictions of NSG. I evaluated the effects of NSG on the soils and vegetation of Nama karoo rangeland in a fully replicated experiment. NSG did not alter the fertile-patch matrix, but improved soil infiltration. Plant compositional and cover changes could not be related to NSG. Rainfall was a much stronger driving force. I also explored the economics of NSG at the farm scale under different rainfall and stocking scenarios. An ecological-economic model predicted that NSG would be a viable option in higher rainfall (>200mm) areas because of the forage buffering capacity which enables the manager to maintain livestock through unpredictable droughts. Restoration strategies for the Succulent Karoo have to focus on the resource-retention capacity of the soils. Livestock can reduce this capacity; low-stocking, ﬂexible farming systems are therefore recommended for these more fragile ecosystems. Livestock in the more resilient Nama Karoo can be managed in a NSG system that can lead to an improvement in ecosystem functioning and maintain productivity in times of drought.

AbstractThe restoration perspective on human adaptation offers a broad view of relations between environment and health; however, it remains underutilized as a source of insight for nature-and-health studies. In this chapter, I start from the restoration perspective in showing ways to extend theory and research concerned with the benefits of nature experience. I first set out the basic premises of the restoration perspective and consider how it has come to have particular relevance for understanding the salutary values now commonly assigned to nature experience. I then discuss the currently conventional theoretical narrative about restorative effects of nature experience and organize some of its components in a general framework for restorative environments theory. Extending the framework, I put forward two additional theories. These call attention to the restoration of resources as held within closer relationships and as held collectively by members of a population. In closing, I consider ways to work with the general framework and further develop the narrative about nature, restoration, and health. The extensions made here raise important considerations for nature preservation efforts, urban planning, health promotion strategies, and ways of thinking about human–nature relations.

Résumé :

AbstractThe large-scale simplification of boreal forest ecosystem structure, composition, and processes to boost timber production, combined with the increasing pressure of climate change, has created an urgent need to restore forest biodiversity and resilience. However, the issue of restoration is relatively new in boreal forests, and there are no established strategies to guide restoration planning and action. Here we provide an overview of suggested strategic concepts and approaches for boreal forest ecosystem restoration and discuss their applicability to various situations. The key strategic questions in restoration for attaining a favorable conservation status of native ecosystem types and their intrinsic dynamics in a given area are: what, how much, and when to restore? We conclude that adaptive capacity should serve as an overarching strategic framework in boreal forest restoration during times of rapid climate change.

Résumé :

Managing potential disruptive events at the operating phase of an engineered system therefore improving the system’s failure resilience is an importance yet challenging task in engineering design. The resilience of an engineered system can be improved by enhancing the failure restoration capability of the system with appropriate system control strategies. Therefore, control-guided failure restoration is an essential step in engineering design for resilience. Considering different characteristics of disruptive events and their impacts to the performance of a system, effective control strategies for the failure restoration must be selected correspondingly. However, the challenge is to develop generally applicable guiding principles for selecting effective control strategies thus implementing the control-guided failure restorations. In this paper, a comparison of three commonly used control strategies for dynamic system control is conducted with the focus on the effectiveness of restoring system performance after the system has undergone different major disruptive events. A case study of an electricity transmission system is used to demonstrate the dynamic system modeling and the comparison of three control strategies for disruption management.

Résumé :

In this paper we address the issues involved in implementing the Linear Programming (LP) method of image restoration in two dimensions. A modified pivot strategy is introduced in order to reduce the number of iterations. This approach is necessary due to the number of arithmetic operations required per iteration for two dimensional data. We shall also discuss the effects of additive noise, such as that due to quantization. The effects of noise on the performance of restorations with both separable and nonseparable degradations will be presented. The performance of the LP approach has previously been seen to show a preference for sparse images C13, i.e. images with many zero valued pixels. This preference is also found in the two dimensional case. The error in the LP restored image is shown to be less for sparse images than it is for dense images with the same signal-to-noise ratio (SNR). Linear Programming, despite its name, is nonlinear. That is, the LP solution of the sum of two images is not necessarily the sum of the two solutions obtained for each image separately. The LP method also allows for inequality as well as equality constraints to be imposed on the solution. The advantage in performance of the constrained nonlinear approach taken here over linear non-constrained methods is also demonstrated. This is accompli shed by illustrating the pseudo-inverse solution for each LP restoration. The pseudo-inverse method represents the optimal non-constrained linear restoration.

Résumé :

Natural disasters may adversely affect coastal resources potentially leading to coastal habitat restorations that incorporate stakeholders and the general public. Appropriate methodologies for habitat restoration are developed to ensure the outcomes of this project. Currently, seagrass bed restoration by means of asexual and sexual propagation techniques have been used worldwide. However, the experience of seagrass (Enhalus acoroides) habitat restoration in Trang Province noted that to accomplish this project’s strategies involved the application of restoration techniques along with public and stakeholder participation. The application of asexual propagation, specifically the collection of single shoots from donor seagrasses and subsequent transplantation, is a convenient tool. However, from this project results, this process still has conceptual problems as from the large numbers of single shoots collected from donor seagrasses, the survival rate was relatively low. Furthermore, this process was complicated by conflicting interests between local communities near to the donor site and the project’s organizers. In order to reduce said conflicts, other techniques to balance stakeholder interests were instigated by this project, namely the development of both asexual and sexual propagation techniques. This project initiated a sexual propagation technique by the collection of wild seeds of Enhalus acoroides that were subsequently grown in the laboratory before natural habitat transplantation. This project results showed that seeds can be grown rapidly and can be cultured in large numbers. However, this development technique has a limit on rearing time because seedlings were found to be in decline after the third month of the experiment. These problems were compounded by a limiting factor that pushed the project’s organizers to decide to transplant seagrasses from the laboratory to the wild whether a time was seasonally suitable or unsuitable, the planting activity still done forward. This matter may have enhanced the low survival rate situation after seagrass transplantation to the wild. If there is a need to recover a seagrass bed, the above culture and transplantation methodologies should be used in conjunction with repeated periodic plantings until natural ecological function has been restored. In conclusion, further research should be instigated to improve the cultivation method for producing ready to plant seedlings and to improve methods of project operation.

Résumé :

Abstract Mitigating the effect of potential disruptive events at the operating phase of an engineered system therefore improving the system’s failure resilience is an importance yet challenging task in system operation. For complex networked system, different stakeholders complicate the analysis process by introducing different characteristics, such as different types of material flow, storage, response time, and flexibility. With different types of systems, the resilience can be improved by enhancing the failure restoration capability of the systems with appropriate performance recovery strategies. These methods include but not limit to, rerouting paths, optimal repair sequence and distributed resource centers. Considering different characteristics of disruptive events, effective recovery strategies for the failure restoration must be selected correspondingly. However, the challenge is to develop a generally applicable framework to optimally coordinate different recovery strategies and thus lead to desirable failure restoration performances. This paper presents a post-disruption recovery decision-making framework for networked systems, to help decision-makers optimize recovery strategies, in which the overall recovery task is formulated as an optimization problem to achieve maximum resilience. A case study of an electricity distribution system is used to demonstrate the feasibility of the developed framework and the comparison of several recovery strategies for disruption management.

Résumé :

In-water beneficial use of dredged sediment provides the US Army Corps of Engineers (USACE) the opportunity to increase beneficial use while controlling costs. Beneficial use projects in riverine environments include bank and near-bank placement, where sediments can protect against bank erosion and support habitat diversity. While bank and near-bank placement of navigation dredged sediment to support river-bank stabilization and habitat is currently practiced, documented examples are sparse. Documenting successful projects can support advancing the practice across USACE. In addition, documentation identifies data gaps required to develop engineering and ecosystem restoration guidance using navigation-dredged sediment. This report documents five USACE and international case studies that successfully applied these practices: Ephemeral Island Creation on the Upper Mississippi River; Gravel Island Creation on the Danube River; Gravel Bar Creation on the Tombigbee River; Wetland Habitat Restoration on the Sacramento-San Joaquin River Delta; and Island and Wetland Creation on the Lower Columbia River Estuary. Increased bank and near-bank placement can have multiple benefits, including reduced dredge volumes that would otherwise increase as banks erode, improved sustainable dredged sediment management strategies, expanded ecosystem restoration opportunities, and improved flood risk management. Data collected from site monitoring can be applied to support development of USACE engineering and ecosystem restoration guidance.
