Abstract:
La pyrolyse haute pression du dibutylether a ete realisee en reacteurs fermes entre 523 et 573 k et entre 0,2 et 2 kbar. Les produits de pyrolyse sont doses par chromatographie gazeuse capillaire et identifies par spectrometrie de masse. Les resultats sont interpretes en termes de reactions radicalaires. Les deux stchiometries principales conduisent au butane et au butanal d'une part, au butane, au propane et au monoxyde de carbone d'autre part. Ces stchiometries sont identiques a celles observees en phase gazeuse pour les ethers analogues. De nombreux autres produits dus a des reactions d'addition radicalaire ont ete identifies. Les effets de la temperature et de la pression sur la cinetique de formation des produits ont ete mesures. Aucune dependance en pression de la vitesse globale de pyrolyse n'a ete observee. La cinetique de pyrolyse a ete modelise. La modelisation rend compte des resultats experimentaux a 573 k-2 bar. Une energie d'activation globale de 56 kcal/mol est en accord avec les donnees experimentales. L'extrapolation aux fortes pressions et aux basses temperatures (350-573 k/2-10 kbar) a mis en evidence une inhibition de la vitesse globale de pyrolyse par les tres fortes pressions. Hautes pressions ou basses temperatures entrainent un changement des stchiometries predominantes avec acceleration des mecanismes secondaires. Les hautes pressions conduisent a des produits plus lourds par acceleration des mecanismes d'addition. Pour etre utilises aux basses temperatures et aux fortes pressions, les modeles d'evolution de la matiere organique naturelle doivent integrer des donnees de chimie radicalaire et tenir compte de la pression

Full text
Abstract:
Cette étude porte sur la réduction des sons auto-entretenus (les sifflements) produits par un écoulement d'air à faible nombre de Mach traversant deux diaphragmes rigides placés en tandem dans un tuyau. Ces sons ont la particularité d'être calés en fréquence sur les résonances acoustiques longitudinales du tube et d'avoir une amplitude très élevée. Typiquement, pour un rapportL/D de distance entre les diaphragmes au diamètre de leur orifice central compris entre 0,4 et 3, le niveau acoustique atteint 130 à 140 dB (re 20 mPa) lorsque le nombre de Reynolds caractéristique varie entre 104 et 105. Afin de réduire ces sons, quatre fentes radiales divergentes sont ménagées sur le diaphragme amont. Les jets secondaires, qui en sortent, ont pour rôle de désorganiser les anneaux tourbillonnaires du jet principal avant qu'ils n'atteignent le diaphragme aval, où ils transforment une partie de leur énergie cinétique en énergie sonore. En variant la vitesse de l'écoulement ou la distance séparant les diaphragmes, Coiret (1999) a montré que le champ acoustique peut bifurquer vers une branche réductrice des sons auto-entretenus jusqu'à 30 dB. Un effet d'hystérésis maintient cette réduction sur une large plage de nombres de Reynolds. A partir d'une exploration du champ de vitesse par anémométrie à fil chaud, nous montrons qu'un effet Coanda se produit sur les jets auxiliaires issus des fentes provoquant leur déflexion vers l'un des deux bords biseautés de la fente. A la suite de ce changement de trajectoire, les jets auxiliaires perturbent davantage les anneaux tourbillonnaires. Ces derniers passent également plus près del'axe du tuyau au niveau des lèvres du diaphragme aval en raison d'une contraction de l'écoulement. Il en résulte une baisse de la production acoustique. Cependant, la réorganisation de l'écoulement a l'inconvénient d'augmenter d'environ 25% la perte de charge créée par les diaphragmes. Une telle méthode passive pourrait avoir des applications industrielles sur les écoulements internes et externes qui sont le siège d'oscillations auto-entretenues
The present study deals with the reduction of the self-sustained tones (the whistling) produced by a low Mach number air flow crossing two rigid baffles in tandem inside a duct. These tones have a single well defined frequency matching the longitudinal acoustic resonance of the pipe and have a high amplitude. Typically, their sound pressure level attains 130 to 140 dB (re 20 mPa) when the ratio between the baffle spacing and the diameter of their aperture belongs to the range [0. 4; 3] and the Reynolds number varies between 104 and 105

Abstract:
Ce manuscrit est consacré à l'étude des effets de pression sur le cloquage des matériaux revêtus. Des expériences par microscopie à force atomique (AFM) ont tout d'abord été réalisées afin de caractériser les structures cloquées présentes à la surface de composites film/substrat. La mesure AFM de la déflexion maximale de ces structures avant et après découpe par faisceaux d'ions localisés (FIB) a alors mis en évidence une augmentation significative de quelques dizaines de nanomètres de leur déflexion. La détermination des formes d'équilibre des films sous l'action d'une pression et d'une contrainte résiduelle dans le cadre du formalisme de Föppl-von Karman (FvK), puis la comparaison de ces formes avec les profils expérimentaux, a permis de justifier la présence de vide sous les cloques. L'effet combiné de la pression et du caractère "rigide" du substrat sur les structures cloquées a ensuite été exploré. Cet effet a permis d'expliquer la limitation de la dimension latérale des cloques. Le deuxième chapitre, dédié aux tests mécaniques par gonflement de membranes (bulge test), a permis de mettre en évidence les limitations des modèles utilisés pour décrire l'évolution de revêtements soumis au bulge test. Plus particulièrement, une pression critique au delà de laquelle ces modèles ne sont plus adaptés a été déterminée en fonction des différents paramètres du problème. Enfin, dans le dernier chapitre, les effets de couplage pression/contrainte internes sur des cloques circulaires, induites sous certaines conditions spécifiques par les dégâts d'irradiations, ont été étudiés également dans le formalisme de FvK. Une méthode permettant d'estimer à partir de la morphologie des cloques, le niveau de la pression dans les cavités engendrées par l'implantation d'ions légers est alors développée
This Thesis is dedicated to the study of the effect of pressure on the buckling phenomenon of thin films. Atomic force Microscopy (AFM) experiments have been first realised to charaterize buckled structures of film/substrate composites. The measurements of the maximal deflection of these structures by AFM before and after focus ion beam (FIB) cuts have evidenced a signicant increase of a few tens of nanometers. The determination of the equilibrium solutions under the action of a pressure mismatch and a residual stress, in the framework of the Föppl-von Karman’s (FvK) theory of thin plates, and the comparison of these solutions with the experimental profiles, have allowed to justify the presence of vacuum below the buckles. The combined effect of the pressure and the "rigid" aspect of the substrate have been also explorated. This effect has been used to explain the limitation of buckle’s lateral size. The second chapter, dedicated to the mechanical testing by bulging of membranes (bulge test), has allowed to evidence the limitations of the classical models used for describing their mechanical evolution. A critical pressure beyond which these models are no more valid has been determined, as a function of the differents parameters of the problem. Finally, in the last chapter, the combined effect of the internal pressure and stress on circular buckles, induced under specific conditions of irradiations, have been also studied in the framewok of the FvK’s theory of thin plates. A new method allowing the estimation of the pressure level inside the cavities from the morphology of the buckles has been developed

Full text
Abstract:
L’énantiosélectivité des réactions d’hydrogénation catalytique asymétrique peut être largement influencée par la concentration en hydrogène dans la phase liquide catalytique, avec généralement un impact néfaste sur l’excès énantiomérique (ee). Dans cette thèse, nous avons démontré, sur une large base de diphosphines chirales (56) et trois substrats prochiraux de type esters d’acylaminoacrylate, représentant une diversité chimique appréciable, que la conclusion d’un effet néfaste de la pression d’hydrogène généralement admis dans la bibliographie est fausse. En effet, sur la base des 168 systèmes catalytiques étudiés (diphosphine/substrat), quasiment autant d’effets néfastes (28%) et bénéfiques (29%) sont observés. D’autre part, les effets électroniques ont également été aussi étudiés sur une famille restreinte de diphosphines de type BINAP par substitution sur le groupe binaphtyle en positions 5,5’ et 4,4’ ou en position para des groupes phényles portés par le phosphore. La plupart de ces dérivés du BINAP ont dû être synthétisés. En particulier de nouvelles méthodes de synthèse des dérivés 5,5’ (Me, COOH, Ph) ont été mises au point et une nouvelle stratégie de synthèse en milieu liquide ionique a été conçue pour la préparation du synthon de base pour les dérivés 4,4’. Dans le cas des dérivés en position para, une corrélation nette entre l’excès énantiomérique et la constante de HAMMETT des substituants (Me, H, NH2, +NMe3, OMe, OH, O-) est obtenue. L’énantiosélectivité peut ainsi être « pilotée », de +57 à –34 %
The enantioselectivity of catalytic asymmetric hydrogenations can be largely influenced by the hydrogen concentration in the catalytic liquid phase, with generally, a negative impact on enantiomeric excess (ee). In this thesis, we showed, on a large number of chiral diphosphine (56) and three prochiral substrates of acylaminoacrylate ester, that the conclusion of a negative effect of the hydrogen pressure generally admitted in the bibliography is wrong. Indeed, on the basis of 168 studied catalytic systems (diphosphine/substrate), an equivalent distribution of negative effects (28%) and beneficial effects (29%) is observed. In addition, the electronic effects were also studied on a restricted family of diphosphines of the BINAP type by substitution on the binaphtyl group in 5,5' and 4,4' position or para of the phenyls groups carried by phosphorus. The majority of these derivatives of the BINAP had to be synthesized. In particular a new method for the synthesis of derived 5,5' (Me, COOH, Ph) was developed and a new strategy of synthesis in ionic liquid medium was designed for the preparation of the 4,4'derivatives. In the case of para derivatives position, a clear correlation between enantiomeric excess and the HAMMETT constant for all the substituents (Me, H, NH2, +NMe3, OMe, OH, O-) is obtained. The enantioselectivity can thus be tuned, from +57 to -34 %

Full text
Abstract:
La diffusion Brillouin stimulée (DBS) constitue un des effets non-linéaires observés dans les fibres optiques monomodes et est d'une grande importance dans diverses applications. Elle résulte de la diffusion des ondes lasers par interaction avec les ondes acoustiques présentes dans le milieu et se manifeste essentiellement par la génération d'une onde Stokes rétrodiffusée, limitant la puissance maximale d'une onde laser transmise dans une fibre optique et impliquant une sévère contrainte pour les transmissions optiques longue distance. Le décalage fréquentiel de cette onde par rapport à l'onde laser est appelé fréquence Brillouin et est proche de 11 GHz à une longueur d'onde 1550 nm. L'analyse de l'onde Stokes permet également l'étude des effets modifiant les caractéristiques acoustiques, telles que la température et la contrainte. C'est pourquoi la DBS est largement utilisée pour la réalisation de capteurs à fibres optiques. Dans ce présent travail de thèse, une étude générale des propriétés de la DBS dans les fibres est proposée, incluant notamment l'établissement d'une nouvelle expression de la puissance de seuil et une solution approchée aux équations Brillouin traditionnelles. A partir de la technique pompe-sonde utilisant une seule source laser grâce à un modulateur électro-optique et qui consiste en l'introduction artificielle d'une onde Stokes contre-propagative que l'on balaye en fréquence, la courbe de gain Brillouin est analysée pour des températures allant de 1K à la température ambiante. La potentialité unique de capteur Brillouin fibré des très basses températures est démontrée et ce avec une sensibilité inférieure à 1ʿC. Les résultats en pression hydrostatique montrent pour la première fois une relation parfaitement linéaire avec la fréquence Brillouin, ce qui fait de la DBS un nouvel outil de mesure de la pression dans les fibres optiques.

Abstract:
Les changements de phase et les propriétés dynamiques du nonadécane-urée ont été étudiés par différentes techniques sous pression (P < 7kbars) : calorimétrie, diffusion Raman, Brillouin, diffusion neutronique, RMN. Le diagramme de phase présente aux basses pressions, deux lignes de transition reliant des phases orthorhombiques à la phase hexagonale haute température alors qu'à haute pression (P > 4kbars) une nouvelle phase orthorhombique gardant la métrique hexagonale apparaît. A 300 K, par diffraction neutronique, le paramètre d'incommensurabilité varie sous l'effet de la pression et une déformation différente des sous-réseaux d'alcane et d'urée est constatée au dessus de 1 kbar. Les défauts de conformation des chaînes étudiés par différentes spectroscopies montrent une variation de leur concentration qui offre d'étonnantes similarités avec la périodicité du sous-réseau d'alcane. Ils expliquent en grande partie, la translation anormalement grande des alcanes le long des canaux.

Abstract:
Without a doubt, the topic of energy--from coal, oil, and nuclear to geothermal, solar and wind--is one of the most pressing across the globe. It is of paramount importance to policy makers, economists, environmentalists, and industry as they consider which technologies to invest in, how to promote use of renewable energy sources, and how to plan for dwindling reserves of non-renewable energy. In Energy: What Everyone Needs to Know, José Goldemberg, a nuclear physicist who has been hailed by Time magazine as one of the world's top "leaders and visionaries on the environment," takes readers through the basics of the world energy system, its problems, and the technical as well as non-technical solutions to the most pressing energy problems. Addressing the issues in a Q-and-A format, Goldemberg answers such questions as: What are wind, wave, and geothermal energy? What are the problems of nuclear waste disposal? What is acid rain? What is the greenhouse gas effect? What is Carbon Capture and Storage? What are smart grids? What is the Kyoto Protocol? What is "cap and trade"? The book sheds light on the role of population growth in energy consumption, renewable energy resources, the amount of available energy reserves (and when they will run out), geopolitical issues, environmental problems, the frequency of environmental disasters, energy efficiency, new technologies, and solutions to changing consumption patterns. It will be the first place to look for information on the vital topic of energy.

Abstract:
This chapter introduces ‘the problem’ of meaningless research in the social sciences. Over the past twenty years there has been an enormous growth in research publications, but never before in the history of humanity have so many social scientists written so much to so little effect. Academic research in the social sciences is often inward looking, addressed to small tribes of fellow researchers, and its purpose in what is increasingly a game is that of getting published in a prestigious journal. A wide gap has emerged between the esoteric concerns of social science researchers and the pressing issues facing today’s societies. The chapter critiques the inaccessibility of the language used by academic researchers, and the formulaic qualities of most research papers, fostered by the demands of the publishing game. It calls for a radical move from research for the sake of publishing to research that has something meaningful to say.

Abstract:
Socialism is back, and with it comes a renewed interest in Marx’s critique of capitalism. After the 2008 financial crash, international book sales of Capital exploded for the first time in decades. In a world of rising income inequality, right-wing nationalisms, and global climate change, people are looking to the father of modern socialism for answers. This book has been written to help those returning to Marx get answers to their pressing questions about the nature of wealth, ecological crisis, gender inequality, colonialism, migration, and the possibility of socialism. This book also offers readers a new perspective on several major ideas in Marx’s work. It argues that Marx, contrary to conventional wisdom, did not think history was deterministic or that reality could be reduced to classical materialism. Marx was not an anthropocentric humanist, nor did he have a labor theory of value. The unique contribution of this book is that it begins with Marx’s earliest and most neglected book on ancient naturalism in order to show its lasting methodological effect on his “process materialism,” defined by the primacy of motion. This “kinetic Marxism” offers a new way to reread Capital that bears directly on a number of contemporary issues. This also makes Marx in Motion the first book to offer a new materialist reading of Marx. The result is a fresh new view on the important theories of primitive accumulation, metabolism, value, fetishism, dialectics, and the possibility of a kinetic communism for the twenty-first century.

Abstract:
Organizations turn to multistakeholder partnerships (MSPs) to meet challenges they cannot handle alone. By tapping diverse stakeholders’ resources, MSPs develop the capability to address complex issues and problems, such as health care delivery, poverty, human rights, watershed management, education, sustainability, and innovation. This book provides a comprehensive understanding of MSPs, why they are needed, the challenges partners face in working together, and how to design them effectively. Through the process of collaboration partners combine their differing strengths, vantage points, and expertise to craft innovative responses to pressing societal concerns. The book offers valuable advice for leaders about how to design and scale up effective partnerships and how to address potential obstacles partners may face, such as dealing with the conflicts and power issues likely to arise as partners negotiate with each other. Drawing on three comprehensive cases and countless shorter examples from around the world, the book offers practical advice for organizations embarking on an MSP, as well as theoretical understanding of how partnerships function. Using an institutional theory lens, it explains how partnerships can effect change in institutional fields by reducing turbulence and negotiating a common set of norms and routines to govern partners’ future interactions within the field of concern. Topics covered include: the nature of working collaboratively, why partnerships are needed, types of partnerships, guidelines for partnership design, partnerships and field dynamics, how to deal with conflicts among partners, negotiating across power differences, partnerships for sustainability, collaborative governance, working across scale differences, and how partnerships transform fields.

Abstract:
While there have always been norms and customs around the use of drugs, explicit public policies--regulations, taxes, and prohibitions--designed to control drug abuse are a more recent phenomenon. Those policies sometimes have terrible side-effects: most prominently the development of criminal enterprises dealing in forbidden (or untaxed) drugs and the use of the profits of drug-dealing to finance insurgency and terrorism. Neither a drug-free world nor a world of free drugs seems to be on offer, leaving citizens and officials to face the age-old problem: What are we going to do about drugs? In Drugs and Drug Policy, three noted authorities survey the subject with exceptional clarity, in this addition to the acclaimed series, What Everyone Needs to Know. They begin by, defining "drugs, " examining how they work in the brain, discussing the nature of addiction, and exploring the damage they do to users. The book moves on to policy, answering questions about legalization, the role of criminal prohibitions, and the relative legal tolerance for alcohol and tobacco. The authors then dissect the illicit trade, from street dealers to the flow of money to the effect of catching kingpins, and show the precise nature of the relationship between drugs and crime. They examine treatment, both its effectiveness and the role of public policy, and discuss the beneficial effects of some abusable substances. Finally they move outward to look at the role of drugs in our foreign policy, their relationship to terrorism, and the ugly politics that surround the issue. Crisp, clear, and comprehensive, this is a handy and up-to-date overview of one of the most pressing topics in today's world.

Abstract:
Introduction : Le plasma atmosphérique froid est un gaz ionisé produit à pression atmosphérique. Plusieurs applications médicales sont étudiées, notamment la cicatrisation des plaies chroniques et l’effet antimicrobien. En effet, le traitement par plasma permet de générer de nombreuses espèces réactives de l’oxygène et de l’azote. L’application d’un tel traitement in-vitro sur des cellules eucaryotes a montré de nombreux effets cellulaires tel que l’apoptose. Les applications dans le domaine de l’oncologie ont par conséquent été étudiées. Objectif : L’objectif de cette revue systématique est d’analyser l’utilisation du plasma atmosphérique froid en oncologie ainsi que les méthodologies (lignées cellulaires ciblées, paramètres physiques, thérapies directes ou indirectes) mises en oeuvre jusqu’à ce jour. Matériels et méthodes : Les bases de données Pubmed, ICTRP et Google Scholar ont été explorées jusqu’au 17/01/2017 afin de recenser les études traitant de l’utilisation du plasma en oncologie, que ce soit des études in-vitro, in-vivo ou des essais cliniques. Résultats : 150 articles originaux ont été inclus. Les Jets de plasma sont les systèmes de production de plasma les plus utilisés (73,3%). L’hélium est le gaz le plus utilisé (34%) suivi par l’air (28%) et l’argon (19,3%). Les études sont principalement in-vitro (94%). L’application directe du plasma est la plus représentée (84,2%). Les lignées cellulaires ciblées sont la plupart dérivées de lignées cancéreuses humaines (82%), en particulier des lignées issues de cancer du cerveau (16,6%). Conclusions : Cette étude met en évidence la multiplicité de moyens de production et d’applications clinques du plasma atmosphérique froid en oncologie. Alors que certains dispositifs peuvent être utilisés directement sur les patients, d’autres ouvrent la voie au développement de nouveaux produits pharmaceutiques qui pourraient être produits à échelle industrielle. L’utilisation clinique du plasma nécessite la mise au point de protocoles fiables et standardisés afin de déterminer le plasma le plus adapté à chaque type de cancers et d’envisager son association avec les traitements conventionnels.

Abstract:
Nitinol shape memory alloy is well known for its shape memory effect and super elastic effect. In the present work, the improvement of mechanical properties of nitinol alloy like yield strength, ultimate tensile strength and micro-hardness is discussed along with the study of evolution of micro-structure after every pass to extend the applications of shape memory alloys into high strength application areas. Severe plastic deformation processes are usually adopted for producing fine grain structures which improve the mechanical properties of a material. One such severe deformation process is constrained groove pressing, which is considered as one of the best severe plastic deformation techniques for sheet metals. The results of constrained groove pressing process on nitinol alloy show that the yield strength and the ultimate tensile strength have increased by about 3.6 times 2.5 times respectively, with an increment of 50% and 74% in micro-hardness after 1st pass of constrained groove pressing and 2nd pass of constrained groove pressing respectively. Microstructure shows increase in martensitic phase after constrained groove pressing processing. Increasing in twinning and grain boundary density can be observed in constrained groove pressing processed nitinol, which are the reasons for the tremendous increase in the strength of the alloy. Thus, the constrained groove pressing process on nitinol alloy can increase its range of application for high strength requirements.

Abstract:
The main recommendations of the panel report can be summarised under five key headings:  Building blocks: The ultimate aim should be to build rich, detailed and testable narratives situated within a European context, and addressing phenomena from the longue durée to the short-term over international to local scales. Chronological control is essential to this and effective dating strategies are required to enable generation-level analysis. The ‘serendipity factor’ of archaeological work must be enhanced by recognising and getting the most out of information-rich sites as they appear. o There is a pressing need to revisit the archives of excavated sites to extract more information from existing resources, notably through dating programmes targeted at regional sequences – the Western Isles Atlantic roundhouse sequence is an obvious target. o Many areas still lack anything beyond the baldest of settlement sequences, with little understanding of the relations between key site types. There is a need to get at least basic sequences from many more areas, either from sustained regional programmes or targeted sampling exercises. o Much of the methodologically innovative work and new insights have come from long-running research excavations. Such large-scale research projects are an important element in developing new approaches to the Iron Age.  Daily life and practice: There remains great potential to improve the understanding of people’s lives in the Iron Age through fresh approaches to, and integration of, existing and newly-excavated data. o House use. Rigorous analysis and innovative approaches, including experimental archaeology, should be employed to get the most out of the understanding of daily life through the strengths of the Scottish record, such as deposits within buildings, organic preservation and waterlogging. o Material culture. Artefact studies have the potential to be far more integral to understandings of Iron Age societies, both from the rich assemblages of the Atlantic area and less-rich lowland finds. Key areas of concern are basic studies of material groups (including the function of everyday items such as stone and bone tools, and the nature of craft processes – iron, copper alloy, bone/antler and shale offer particularly good evidence). Other key topics are: the role of ‘art’ and other forms of decoration and comparative approaches to assemblages to obtain synthetic views of the uses of material culture. o Field to feast. Subsistence practices are a core area of research essential to understanding past society, but different strands of evidence need to be more fully integrated, with a ‘field to feast’ approach, from production to consumption. The working of agricultural systems is poorly understood, from agricultural processes to cooking practices and cuisine: integrated work between different specialisms would assist greatly. There is a need for conceptual as well as practical perspectives – e.g. how were wild resources conceived? o Ritual practice. There has been valuable work in identifying depositional practices, such as deposition of animals or querns, which are thought to relate to house-based ritual practices, but there is great potential for further pattern-spotting, synthesis and interpretation. Iron Age Scotland: ScARF Panel Report v  Landscapes and regions:  Concepts of ‘region’ or ‘province’, and how they changed over time, need to be critically explored, because they are contentious, poorly defined and highly variable. What did Iron Age people see as their geographical horizons, and how did this change?  Attempts to understand the Iron Age landscape require improved, integrated survey methodologies, as existing approaches are inevitably partial.  Aspects of the landscape’s physical form and cover should be investigated more fully, in terms of vegetation (known only in outline over most of the country) and sea level change in key areas such as the firths of Moray and Forth.  Landscapes beyond settlement merit further work, e.g. the use of the landscape for deposition of objects or people, and what this tells us of contemporary perceptions and beliefs.  Concepts of inherited landscapes (how Iron Age communities saw and used this longlived land) and socal resilience to issues such as climate change should be explored more fully.  Reconstructing Iron Age societies. The changing structure of society over space and time in this period remains poorly understood. Researchers should interrogate the data for better and more explicitly-expressed understandings of social structures and relations between people.  The wider context: Researchers need to engage with the big questions of change on a European level (and beyond). Relationships with neighbouring areas (e.g. England, Ireland) and analogies from other areas (e.g. Scandinavia and the Low Countries) can help inform Scottish studies. Key big topics are: o The nature and effect of the introduction of iron. o The social processes lying behind evidence for movement and contact. o Parallels and differences in social processes and developments. o The changing nature of houses and households over this period, including the role of ‘substantial houses’, from crannogs to brochs, the development and role of complex architecture, and the shift away from roundhouses. o The chronology, nature and meaning of hillforts and other enclosed settlements. o Relationships with the Roman world
