Résumé :
According to the characteristics of the fringe patterns noise, came up with a small area spin filtering noise cancellation algorithm based on parallel marker technology. It means that preprocess the fringe pattern before spin filtering, then did a median filter and calculated the stripe direction, finally used the extract the fringe direction to spin filtering of the original image. The algorithm can marked several targets in scanning process at the same time. So it has a high efficiency. The algorithm can be used in the multi-frequency heterodyne phase shift technology .And we can use the technology to complete the measurement of complex surfaces. Experimental results show that the method has a distinct advantage in measurement accuracy, measurement speed, and noise immunity.

Résumé :
In this paper the harmonic stability is investigated for multi paralleled three-phase photovoltaic inverters connected to grid. The causes to harmonically stabilize/destabilize the multi-paralleled PV inverters when tied to the grid isanalysed by the impedance-based stability criterion (IBSC). In this paper stability of the system is investigated by varying the grid inductance with constant grid resistance and also by varying load impedance while maintaining grid inductance constant. Stability of the multiple three phase inverters tied to the grid with different grid impedance, inductance value inparticular are analyzed. Overall system is stable up to grid inductance of5mH even though there is change in load admittance. It is concluded that system stability depends only on grid impedance. It is verified with Matlab Simulations.

Résumé :
Chloride-induced corrosion of reinforcing steel in concrete is a worldwide problem. In order to predict how chlorides penetrate in concrete and how other ionic species in con-crete pore solution affect the penetration of chlorides, this thesis presents a numerical study on multi-phase modelling of ionic transport in concrete dominated by migration process. There are many advantages in rapid chloride migration test (RCM) method and numeri-cal approach. However, most of models in the literature predicting chloride diffusivity in concrete are diffusion models, which not consider the action of externally applied electric field. In view of this, the specific aim of this thesis is to develop a rational nu-merical migration model to simulate chloride migration tests. By using this model, the diffusion coefficient of chlorides in concrete will be efficiently predicted. Furthermore, other mechanisms of ionic transportation in composite materials can be scientifically in-vestigated in the meantime. In most existing work, researchers tend to use the assumption of electro-neutrality con-dition, which ensures that no external charge can be imported (Bockris and Reddy, 1998), to determine the electrostatic potential within concrete as well as considering a 1-D problem with only one phase structure and single species (i.e. the chlorides) for pre-dicting the ionic migration. In contrast, this thesis presents a number of sets of multi-phase migration models in more than one dimension and uses the Poisson’s equation for controlling the multi-species interactions. By solving both mass conservation and Pois-son’s equations, the distribution profiles of each ionic species and electrostatic potential at any required time are successfully obtained. Some significant factors, i.e. the influ-ence of dimensions, aggregates, interfacial transition zones (ITZs), cracks and binding effect have also been discussed in detail. The results reveal a series of important features which may not be seen from existing numerical models. For quantitative study, this thesis also provides the prediction method of chloride diffu-sivity not only by the traditional stationary diffusion models but also by the migration models presented in the thesis. The obtained results are compared with three proven analytical models, i.e., Maxwell’s model (Dormieux and Lemarchand, 2000), Brug-geman’s equation (Bruggeman’s, 1935) and the lower bound of the effective diffusion coefficient proposed by Li et al. (2012) as well as validated against experimental data sets of an accelerated chloride migration test (ACMT) brought by Yang and Su (2002).

Résumé :
Multi-pulse converters have been widely used for a multi-megawatt scale power generating system to comply with harmonic regulations. Among all types of multi-pulse converters, a 12-pulse converter is the most widely used due to the simple structure, which consists of a delta-delta and a delta-wye phase-shift transformer pair and it effectively mitigates undesirable harmonics from the nonlinear load. In the early 2000s, a shunt type passive front-end for a shipboard power system was proposed. By shunting the two gensets with 30° phase angle difference, a single phase-shift transformer effectively eliminates 5th and 7th harmonics. It achieves a significant size and weight reduction compared to a 12-pulse converter while keep the comparable harmonic cancellation performance. Recently, a hybrid type front-end was proposed. On top of the passive front-end, 3 phase active power filter was added and an additional harmonic cancellation was achieved to further eliminate 11th and 13th harmonics. However, the performance of both the passive and hybrid type front-end are highly dependent on the size of the line reactor in ac mains. A back to back active power filter is proposed in this dissertation to replace the phase-shift transformer in the multi-generator power architecture. The proposed front-end does not include phase-shift transformer and the size and the weight of the overall front-end can be significantly reduced. Due to the active harmonic compensation, the back to back front-end achieves better power quality and the line reactor dependency is improved. The number of required dc-link capacitors is reduced by half by introducing a back to back configuration and the capacitor size is reduced by adjusting the phase angle difference of genset to cancel out the most significant voltage harmonics in the shared dc-link bus. The overview of the existing shunt type front-end is provided and the concept of back to back active power filter is validated by simulation and prototype hardware. The comparison between existing front-end and the proposed front-end is provided to highlight the superior performance of back to back active front-end. The dc-link bus current and voltage ripple analysis is provided to explain the dc-link ripple reduction mechanism.

The transportation electrification has gained more and more attention due to its smaller carbon dioxide emission, better fuel efficiency. The recent advances in power devices, microcontrollers, and transducers accelerate the electrification of transportation. This trend is shown in the propulsion system in marine transport as well and the electric propulsion system has been widely used to meet the strict environmental regulations. However, the non-linear circuit components such as capacitor and diode in the electric propulsion system draw non-linear current and significantly deteriorate power quality and lead to critical problems such as reduced life span of circuit components Accordingly, a front-end is required to improve power quality. Also, it is desired to have compact and lightweight front-end for installation flexibility and fuel efficiency improvement. In this dissertation, several front-ends using a phase-shift transformer are reviewed and a detailed analysis is provided to help understand the harmonic cancellation principle of the existing front-end through equivalent circuit analysis, quantitative analysis, and a phasor diagram representation. Based on the analysis of the existing front-ends and shipboard power architecture, lightweight and high-performance front-end is proposed and verified by simulation and prototype hardware. The performance, size comparison between existing front-end and the proposed front-end is provided to show the advantage of the proposed front-end.

Résumé :

Problem: Fear of a painful dental injection and subsequent avoidance behavior are significant barriers to regular visits to the dentist. An anesthetic procedure that would avoid the discomfort of a local anesthetic injection thus obviating fear and anxiety about receiving a “shot,” would greatly benefit dental patients.

Methods: The study employed a multi-center, randomized, double-blind, placebo-controlled, parallel-groups design to assess the safety and efficacy of Kovacaine Mist delivered intranasally for inducing pulpal anesthesia of maxillary teeth sufficient to allow completion of the Study Dental Procedure. A total of 36 subjects, randomized 2:1 (Kovacaine Mist: Placebo) were enrolled.

Results: Kovacaine Mist was significantly superior to placebo (p<0.0001) with respect to the proportion of subjects who did not require rescue by injection of local anesthetic to complete the Study Dental Procedure.

Conclusions: Based of the results of this clinical trial, a nasal anesthetic, such as kovacaine mist, could potentially be used as a safe and effective alternative to maxillary infiltration for anesthetizing maxillary premolars and anteriors to achieve pulpal anesthesia.

Résumé :
La mesure de la forme 3D du visage est une problématique qui attire de plus en plus de chercheurs et qui trouve son application dans des domaines divers tels que la biométrie, l'animation et la chirurgie faciale. Les solutions actuelles sont souvent basées sur des systèmes projecteur/caméra et utilisent de la lumière structurée pour compenser l'insuffisance de la texture faciale. L'information 3D est ensuite calculée en décodant la distorsion des patrons projetés sur le visage. Une des techniques les plus utilisées de la lumière structurée est la codification sinusoïdale par décalage de phase qui permet une numérisation 3D de résolution pixélique. Cette technique exige une étape de déroulement de phase, sensible à l'éclairage ambiant surtout quand le nombre de patrons projetés est limité. En plus, la projection de plusieurs patrons impacte le délai de numérisation et peut générer des artefacts surtout pour la capture d'un visage en mouvement. Une alternative aux approches projecteur-caméra consiste à estimer l'information 3D par appariement stéréo suivi par une triangulation optique. Cependant, le modèle calculé par cette technique est généralement non-dense et manque de précision. Des travaux récents proposent la super-résolution pour densifier et débruiter les images de profondeur. La super-résolution a été particulièrement proposée pour les caméras 3D TOF (Time-Of-Flight) qui fournissent des scans 3D très bruités. Ce travail de thèse propose une solution de numérisation 3D à faible coût avec un schéma de super-résolution spatio-temporelle. Elle utilise un système multi-caméra étalonné assisté par une source de projection non-étalonnée. Elle est particulièrement adaptée à la reconstruction 3D de visages, i.e. rapide et mobile. La solution proposée est une approche hybride qui associe la stéréovision et la codification sinusoïdale par décalage de phase, et qui non seulement profite de leurs avantages mais qui surmonte leurs faiblesses. Le schéma de la super-résolution proposé permet de corriger l'information 3D, de compléter la vue scannée du visage en traitant son aspect déformable.

Résumé :
Nowadays we are witnessing a strong growth in the full electric vehicle market. In the field of traction the requirements are low weight, small dimensions and low cost, without renouncing reliability and good performances. The high power density requirement is pushing the research towards integrated drive solutions. A particular drive that allows to obtain more insightful integrated solutions is the multi-phase one. In fact, in multi-phase structures it is possible to realize a converter as a combination of standard modules with an equal subdivision of the current. The resulting power electronics modules meet the needs of an integrated solution: smaller and widely distributed. Although road electric vehicles primarily adopt 3-phase drives, the multi-phase version could represent a good alternative not only for its integration capability but also for other features like reduced weight and volume, high efficiency, low vibrations and noise, robustness and, overall, fault tolerance. The aim of this thesis is to investigate a particular category of multiphase machines, characterized by a very simple structure that allows to match manufacturing and performance standards. In Chapter 1, the subcategory of multiphase machine object of the investigation is identified. Considering a simple stator structure, as the tooth-coil wound, a general algorithm to identify the right stator-rotor coupling in multiphase machine is presented. In Chapter 2, an analytical and generalized formulation of the harmonic fields at the air gap for the multi-n-phase solutions chosen is reported allowing to understand and quantify the harmonic compensation in the MMF. Starting from the Lorenz Force Law an analytical formulation of the torque and torque ripple is then proposed. The model proposed has been then verified by Finite Element Analysis (FEA). In Chapter 3, the main issues tackled in the design of a nine phase machine are reported. Between the possible solutions a 9 slot 10 poles PM-inset machine has been chosen. The chapter reports the evaluation of the performance conducted by the time stepping FEA. The chapter reports the experimental results that were conducted on a prototype. A description of the control infrastructure is reported. In Chapter 4, a simple modulation strategy that allows to reduce the DC-link stress for a triple-3-phase drive is presented. The analysis of the benefits introduced by the PWM phase shifting are evaluated by steady state simulations ,using the software Pspice, in all the possible operating conditions. A worst case approach has been chosen in order to find the best angle of shifting between carriers to reduce the DC-link rms current in multi-3-phase drives. The results of the experimental validation are reported. The same analysis has been extended to sectored multiphase. In Chapter 5, a mathematical model is proposed in order to evaluate the torque and the torque ripple in fractional slot tooth-coil wound (TCW) Synchronous Reluctance (SyR) machines. Considering a generic harmonic field and an ideal SyR rotor, the rotor magnetic potential is modelled and the torque equations are calculated starting from the Lorenz Force Law. Time stepping FEA results are reported in order to verify the formulations. Appendix A reports the mathematical demonstration that defines the rotor reaction for an ideal SyR rotor together with the methodologies used to design the SyR constant permeance rotor. Appendix B reports the manufacturing process of the machine. Appendix C reports the COOL-TIE concept: a cooling devices for the electrical machine compatible with the power electronic integration

Résumé :
Cette thèse s'intéresse à la simulation numérique de l'explosion vapeur. Ce phénomène correspond à une vaporisation instantanée d'un volume d'eau liquide entraînant un choc de pression. Nous nous y intéressons dans le cadre de la sûreté nucléaire. En effet, lors d'un accident entraînant la fusion du cœur du réacteur, du métal fondu pourrait interagir avec de l'eau liquide et entraîner un tel choc. On voudrait alors connaître l'ampleur de ce phénomène et les risques d'endommagements de la centrale qu'il implique. Pour y parvenir, nous utilisons pour modèle les équations d'Euler dans un cadre Lagrangien. Cette description a l'avantage de suivre les fluides au cours du temps et donc de parfaitement conserver les interfaces entre l'eau liquide et sa vapeur. Pour résoudre numériquement les équations obtenues, nous développons un nouveau schéma de type Godunov utilisant des flux nodaux. Le solveur nodal développé durant cette thèse ne dépend que de la répartition angulaire des variables physiques autour du nœud. De plus, nous nous intéressons aux changements de phase liquide-vapeur. Nous proposons une méthode pour les prendre en compte et mettons en avant les avantages qu'il y a à l'implémentation de ce phénomène dans un algorithme Lagrangien
This thesis studies numerical simulation of steam explosion. This phenomenon correspond to a fast vaporization of a liquid leading to a pressure shock. It is of interest in the nuclear safety field. During a core-meltdown crisis, molten fuel rods interacting with water could lead to steam explosion. Consequently we want to evaluate the risks created by this phenomenon.In order to do it, we use Euler equations written in a Lagrangian form. This description has the advantage of following the fluid motion and consequently preserves interfaces between the liquid and its vapor. To solve these equations, we develop a new Godunov type scheme using nodal fluxes. The nodal solver developed here only depends on the angular repartition of the physical variables around the node.Moreover, we study liquid-vapor phase changes. We describe a method to take it into account and highlight the advantages of using this method into a Lagrangian framework

Résumé :
Une élévation majeure de la charge mutationnelle (hypermutation) est observée dans certains gliomes. Néanmoins, les mécanismes de ce phénomène et ses implications thérapeutiques notamment concernant la réponse à la chimiothérapie ou à l'immunothérapie sont encore mal connus. Sur le plan du mécanisme, une association entre hypermutation et mutations des gènes de la voie de réparation des mésappariements de l'ADN (MMR) a été rapportée dans les gliomes, cependant la plupart des mutations MMR observées dans ce contexte n'étaient pas fonctionnellement caractérisées, et leur rôle dans le développement d’hypermutation restait de ce fait incertain. De plus, l'impact de l'hypermutation sur l'immunogénicité des cellules gliales et sur leur sensibilité au blocage des points de contrôles immunitaires (par exemple par traitement anti-PD-1) n’est pas connu. Dans cette étude, nous analysons de manière exhaustive les déterminants cliniques et moléculaires de la charge et des signatures mutationnelle dans 10 294 gliomes, dont 558 (5,4%) tumeurs hypermutées. Nous identifions deux principales voies responsables d'hypermutation dans les gliomes : une voie "de novo" associée à des déficits constitutionnels du système MMR et de la polymérase epsilon (POLE), ainsi qu'une voie "post-traitement", plus fréquente, associée à l'acquisition de déficits MMR et de résistance secondaire dans les gliomes récidivant après chimiothérapie par temozolomide. Expérimentalement, la signature mutationnelle des gliomes hypermutés post-traitement (signature COSMIC 11) était reproduite par les dommages induits par le témozolomide dans les cellules MMR déficientes. Alors que le déficit MMR s'associe à l'acquisition de résistance au témozolomide, des données cliniques et expérimentales suggèrent que les cellules MMR déficientes conservent une sensibilité à la nitrosourée lomustine. De façon inattendue, les gliomes MMR déficients présentaient des caractéristiques uniques, notamment l'absence d'infiltrats lymphocytaires T marqués, une hétérogénéité intratumorale importante, une survie diminuée ainsi qu’un faible taux de réponse aux traitements anti-PD-1. De plus, alors que l'instabilité des microsatellites n'etait pas détectée par des analyses en bulk dans les gliomes MMR déficients, le séquençage du génome entier à l'échelle de la cellule unique de gliome hypermuté post-traitement permettait de démontrer la presence de mutations des microsatellites. Collectivement, ces résultats supportent un modèle dans lequel des spécificités dans le profil mutationnel des gliomes hypermutés pourraient expliquer l’absence de reconnaissance par le système immunitaire ainsi que l’absence de réponse aux traitements par anti-PD-1 dans les gliomes MMR déficients. Nos données suggèrent un changement de pratique selon lequel la recherche d’hypermutation par séquençage tumoral lors de la récidive après traitement pourrait informer le pronostic et guider la prise en charge thérapeutique des patients
High tumor mutational burden (hypermutation) is observed in some gliomas; however, the mechanisms by which hypermutation develops and whether it predicts chemotherapy or immunotherapy response are poorly understood. Mechanistically, an association between hypermutation and mutations in the DNA mismatch-repair (MMR) genes has been reported in gliomas, but most MMR mutations observed in this context were not functionally characterized, and their role in causing hypermutation remains unclear. Furthermore, whether hypermutation enhances tumor immunogenicity and renders gliomas responsive to immune checkpoint blockade (e.g. PD-1 blockade) is not known. Here, we comprehensively analyze the clinical and molecular determinants of mutational burden and signatures in 10,294 gliomas, including 558 (5.4%) hypermutated tumors. We delineate two main pathways to hypermutation: a de novo pathway associated with constitutional defects in DNA polymerase and MMR genes, and a more common, post-treatment pathway, associated with acquired resistance driven by MMR defects in chemotherapy-sensitive gliomas recurring after temozolomide. Experimentally, the mutational signature of post-treatment hypermutated gliomas (COSMIC signature 11) was recapitulated by temozolomide-induced damage in MMR-deficient cells. While MMR deficiency was associated with acquired temozolomide resistance in glioma models, clinical and experimental evidence suggest that MMR-deficient cells retain sensitivity to the chloroethylating nitrosourea lomustine. MMR-deficient gliomas exhibited unique features including the lack of prominent T-cell infiltrates, extensive intratumoral heterogeneity, poor survival and low response rate to PD-1 blockade. Moreover, while microsatellite instability in MMR-deficient gliomas was not detected by bulk analyses, single-cell whole-genome sequencing of post-treatment hypermutated glioma cells demonstrated microsatellite mutations. Collectively, these results support a model where differences in the mutation landscape and antigen clonality of MMR-deficient gliomas relative to other MMR-deficient cancers may explain the lack of both immune recognition and response to PD-1 blockade in gliomas. Our data suggest a change in practice whereby tumor re-sequencing at relapse to identify progression and hypermutation could inform prognosis and guide therapeutic management

Résumé :
AbstractReal-time systems are notoriously hard to verify due to nondeterminism, concurrency and timing constraints. When timing constants are uncertain (in early the design phase, or due to slight variations of the timing bounds), timed model checking techniques may not be satisfactory. In contrast, parametric timed model checking synthesizes timing values ensuring correctness. takes as input an extension of parametric timed automata (PTAs), a powerful formalism to formally verify critical real-time systems. extends PTAs with multi-rate clocks, global rational-valued variables and a set of additional useful features. We describe here the new features and algorithms offered by 3, that moved along the years from a simple prototype dedicated to robustness analysis to a standalone parametric model checker for timed systems.

Résumé :
This report is one of a series of reports documenting the methods and findings of a multi-year, multi-disciplinary project coordinated by the Pacific Earthquake Engineering Research Center (PEER and funded by the California Earthquake Authority (CEA). The overall project is titled “Quantifying the Performance of Retrofit of Cripple Walls and Sill Anchorage in Single-Family Wood-Frame Buildings,” henceforth referred to as the “PEER–CEA Project.” The overall objective of the PEER–CEA Project is to provide scientifically based information (e.g., testing, analysis, and resulting loss models) that measure and assess the effectiveness of seismic retrofit to reduce the risk of damage and associated losses (repair costs) of wood-frame houses with cripple wall and sill anchorage deficiencies as well as retrofitted conditions that address those deficiencies. Tasks that support and inform the loss-modeling effort are: (1) collecting and summarizing existing information and results of previous research on the performance of wood-frame houses; (2) identifying construction features to characterize alternative variants of wood-frame houses; (3) characterizing earthquake hazard and ground motions at representative sites in California; (4) developing cyclic loading protocols and conducting laboratory tests of cripple wall panels, wood-frame wall subassemblies, and sill anchorages to measure and document their response (strength and stiffness) under cyclic loading; and (5) the computer modeling, simulations, and the development of loss models as informed by a workshop with claims adjustors. This report is a product of Working Group 4: Testing and focuses on the first phase of an experimental investigation to study the seismic performance of retrofitted and existing cripple walls with sill anchorage. Paralleled by a large-component test program conducted at the University of California [Cobeen et al. 2020], the present study involves the first of multiple phases of small-component tests conducted at the UC San Diego. Details representative of era-specific construction, specifically the most vulnerable pre-1960s construction, are of predominant focus in the present effort. Parameters examined are cripple wall height, finish materials, gravity load, boundary conditions, anchorage, and deterioration. This report addresses the first phase of testing, which consisted of six specimens. Phase 1 including quasi-static reversed cyclic lateral load testing of six 12-ft-long, 2-ft high cripple walls. All specimens in this phase were finished on their exterior with stucco over horizontal sheathing (referred to as a “wet” finish), a finish noted to be common of dwellings built in California before 1945. Parameters addressed in this first phase include: boundary conditions on the top, bottom, and corners of the walls, attachment of the sill to the foundation, and the retrofitted condition. Details of the test specimens, testing protocol, instrumentation; and measured as well as physical observations are summarized in this report. In addition, this report discusses the rationale and scope of subsequent small-component test phases. Companion reports present these test phases considering, amongst other variables, the impacts of dry finishes and cripple wall height (Phases 2–4). Results from these experiments are intended to provide an experimental basis to support numerical modeling used to develop loss models, which are intended to quantify the reduction of loss achieved by applying state-of-practice retrofit methods as identified in FEMA P-1100, Vulnerability-Base Seismic Assessment and Retrofit of One- and Two-Family Dwellings.

This report is a product of Working Group 4 (WG4): Testing, whose central focus was to experimentally investigate the seismic performance of retrofitted and existing cripple walls. This report focuses stucco or “wet” exterior finishes. Paralleled by a large-component test program conducted at the University of California, Berkeley (UC Berkeley) [Cobeen et al. 2020], the present study involves two of multiple phases of small-component tests conducted at the University of California San Diego (UC San Diego). Details representative of era-specific construction, specifically the most vulnerable pre-1960s construction, are of predominant focus in the present effort. Parameters examined are cripple wall height, finish style, gravity load, boundary conditions, anchorage, and deterioration. This report addresses the third phase of testing, which consisted of eight specimens, as well as half of the fourth phase of testing, which consisted of six specimens where three will be discussed. Although conducted in different phases, their results are combined here to co-locate observations regarding the behavior of the second phase the wet (stucco) finished specimens. The results of first phase of wet specimen tests were presented in Schiller et al. [2020(a)]. Experiments involved imposition of combined vertical loading and quasi-static reversed cyclic lateral load onto ten cripple walls of 12 ft long and 2 or 6 ft high. One cripple wall was tested with a monotonic loading protocol. All specimens in this report were constructed with the same boundary conditions on the top and corners of the walls as well as being tested with the same vertical load. Parameters addressed in this report include: wet exterior finishes (stucco over framing, stucco over horizontal lumber sheathing, and stucco over diagonal lumber sheathing), cripple wall height, loading protocol, anchorage condition, boundary condition at the bottom of the walls, and the retrofitted condition. Details of the test specimens, testing protocol, including instrumentation; and measured as well as physical observations are summarized in this report. Companion reports present phases of the tests considering, amongst other variables, impacts of various boundary conditions, stucco (wet) and non-stucco (dry) finishes, vertical load, cripple wall height, and anchorage condition. Results from these experiments are intended to support advancement of numerical modeling tools, which ultimately will inform seismic loss models capable of quantifying the reduction of loss achieved by applying state-of-practice retrofit methods as identified in FEMA P-1100,Vulnerability-Base Seismic Assessment and Retrofit of One- and Two-Family Dwellings.

Three primary tasks support the earthquake loss-modeling effort. They are: (1) the development of ground motions and loading protocols that accurately represent the diversity of seismic hazard in California; (2) the execution of a suite of quasi-static cyclic experiments to measure and document the performance of cripple wall and sill anchorage deficiencies to develop and populate loss models; and (3) nonlinear response history analysis on cripple wall-supported buildings and their components.

Führ, Martin, Julian Schenten et Silke Kleihauer. Integrating "Green Chemistry" into the Regulatory Framework of European Chemicals Policy. Sonderforschungsgruppe Institutionenanalyse, juillet 2019. http://dx.doi.org/10.46850/sofia.9783941627727.

Texte intégral
Résumé :
20 years ago a concept of “Green Chemistry” was formulated by Paul Anastas and John Warner, aiming at an ambitious agenda to “green” chemical products and processes. Today the concept, laid down in a set of 12 principles, has found support in various arenas. This diffusion was supported by enhancements of the legislative framework; not only in the European Union. Nevertheless industry actors – whilst generally supporting the idea – still see “cost and perception remain barriers to green chemistry uptake”. Thus, the questions arise how additional incentives as well as measures to address the barriers and impediments can be provided. An analysis addressing these questions has to take into account the institutional context for the relevant actors involved in the issue. And it has to reflect the problem perception of the different stakeholders. The supply chain into which the chemicals are distributed are of pivotal importance since they create the demand pull for chemicals designed in accordance with the “Green Chemistry Principles”. Consequently, the scope of this study includes all stages in a chemical’s life-cycle, including the process of designing and producing the final products to which chemical substances contribute. For each stage the most relevant legislative acts, together establishing the regulatory framework of the “chemicals policy” in the EU are analysed. In a nutshell the main elements of the study can be summarized as follows: Green Chemistry (GC) is the utilisation of a set of principles that reduces or eliminates the use or generation of hazardous substances in the design, manufacture and application of chemical products. Besides, reaction efficiency, including energy efficiency, and the use of renewable resources are other motives of Green Chemistry. Putting the GC concept in a broader market context, however, it can only prevail if in the perception of the relevant actors it is linked to tangible business cases. Therefore, the study analyses the product context in which chemistry is to be applied, as well as the substance’s entire life-cycle – in other words, the six stages in product innovation processes): 1. Substance design, 2. Production process, 3. Interaction in the supply chain, 4. Product design, 5. Use phase and 6. After use phase of the product (towards a “circular economy”). The report presents an overview to what extent the existing framework, i.e. legislation and the wider institutional context along the six stages, is setting incentives for actors to adequately address problematic substances and their potential impacts, including the learning processes intended to invoke creativity of various actors to solve challenges posed by these substances. In this respect, measured against the GC and Learning Process assessment criteria, the study identified shortcomings (“delta”) at each stage of product innovation. Some criteria are covered by the regulatory framework and to a relevant extent implemented by the actors. With respect to those criteria, there is thus no priority need for further action. Other criteria are only to a certain degree covered by the regulatory framework, due to various and often interlinked reasons. For those criteria, entry points for options to strengthen or further nuance coverage of the respective principle already exist. Most relevant are the deltas with regard to those instruments that influence the design phase; both for the chemical substance as such and for the end-product containing the substance. Due to the multi-tier supply chains, provisions fostering information, communication and cooperation of the various actors are crucial to underpin the learning processes towards the GCP. The policy options aim to tackle these shortcomings in the context of the respective stage in order to support those actors who are willing to change their attitude and their business decisions towards GC. The findings are in general coherence with the strategies to foster GC identified by the Green Chemistry & Commerce Council.

Texte intégral
Résumé :
The main recommendations of the panel report can be summarised under five key headings. Underpinning all five areas is the recognition that human narratives remain crucial for ensuring the widest access to our shared past. There is no wish to see political and economic narratives abandoned but the need is recognised for there to be an expansion to more social narratives to fully explore the potential of the diverse evidence base. The questions that can be asked are here framed in a national context but they need to be supported and improved a) by the development of regional research frameworks, and b) by an enhanced study of Scotland’s international context through time. 1. From North Britain to the Idea of Scotland: Understanding why, where and how ‘Scotland’ emerges provides a focal point of research. Investigating state formation requires work from Medieval Scotland: a future for its past ii a variety of sources, exploring the relationships between centres of consumption - royal, ecclesiastical and urban - and their hinterlands. Working from site-specific work to regional analysis, researchers can explore how what would become ‘Scotland’ came to be, and whence sprang its inspiration. 2. Lifestyles and Living Spaces: Holistic approaches to exploring medieval settlement should be promoted, combining landscape studies with artefactual, environmental, and documentary work. Understanding the role of individual sites within wider local, regional and national settlement systems should be promoted, and chronological frameworks developed to chart the changing nature of Medieval settlement. 3. Mentalities: The holistic understanding of medieval belief (particularly, but not exclusively, in its early medieval or early historic phase) needs to broaden its contextual understanding with reference to prehistoric or inherited belief systems and frames of reference. Collaborative approaches should draw on international parallels and analogues in pursuit of defining and contrasting local or regional belief systems through integrated studies of portable material culture, monumentality and landscape. 4. Empowerment: Revisiting museum collections and renewing the study of newly retrieved artefacts is vital to a broader understanding of the dynamics of writing within society. Text needs to be seen less as a metaphor and more as a technological and social innovation in material culture which will help the understanding of it as an experienced, imaginatively rich reality of life. In archaeological terms, the study of the relatively neglected cultural areas of sensory perception, memory, learning and play needs to be promoted to enrich the understanding of past social behaviours. 5. Parameters: Multi-disciplinary, collaborative, and cross-sector approaches should be encouraged in order to release the research potential of all sectors of archaeology. Creative solutions should be sought to the challenges of transmitting the importance of archaeological work and conserving the resource for current and future research.
