Abstract (sommario):
Cette thèse est centrée sur les délibérations du tribunal de la Mercanzia de Florence. Pour les Florentins, l’accès au port de Pise, dont il est indirectement possible de reconstituer le trafic, est crucial et transcende les relations compliquées entre les deux villes. Mais, s’ils sont prêts à quitter Pise (1356-1369 et 1399-1406) ou à déclencher des guerres (1362-1364 et 1397-1398) pour défendre leurs exemptions de droits de douanes et de gabelles, leur analyse précise prouve la faible incidence sur les prix de vente. Ces sommes sont en réalité transférées à la nation florentine, dont la direction est bicéphale (un consul pisan, un notaire-syndic florentin). La découverte d’un statut de la nation (1381) permet de mieux connaître le rôle des dirigeants et la conservation d’un livre de compte (1374-1382) éclaire leur rémunération. Les structures communautaires sont centrées sur le fondaco de Porto Pisano, géré par la commune pisane, et sur la loggia, située dans le palais du seigneur de Pise de 1369 à 1392, ou 1395, date à laquelle la nation est transférée à Livourne et Piombino. Une double certification de la citoyenneté, par le serment de deux marchands et par l’envoi de lettres de la Mercanzia, est également mise en place. Les listes des traités bilatéraux ne recensent que les compagnies habilitées à prêter serment, ce qui rend difficile la prosopographie de la communauté. Le dernier chapitre montre la formation d’un champ judiciaire commun, capable de fonctionner durant les périodes de tension, à travers l’examen des procédures et du règlement de conflits concernant les franchises de taxes, le règlement des faillites et l’application du droit de représailles
This PhD thesis focuses on the Deliberazioni of the Florentine court called Mercanzia. Access to the port of Pisa, the traffic of which can indirectly be reconstructed, is essential for Florentine people and transcends the difficult relationships between both cities. They are ready to leave Pisa (1356-1369 and 1399-1406) or to go to war (1362-1364 and 1397-1398) to defend their tax and customs exemptions, but an analysis of the specifics shows a weak impact on prices. These sums are transferred to two-headed Florentine natio (one Pisan consul, one Florentine notary-sindaco). The discovery of the natio’s statute (1381) improves our knowledge of the managers’ duties and the remaining accounts shows how they are paid. The structures of the community are concentrated on the fondaco of Porto Pisano, which is administrated by the Pisan city-state (commune), and on the loggia, located in the Pietro Gambacorta’s palace in Pisa from 1369 to 1392, or 1395, the year when the natio was transferred to Livorno and Piombino. Double certification of citizenship, first by an oath sworn by two merchants, second by the sending of letters by the Mercanzia, does exist. Lists in bilateral treaties only register the companies, whose members are able to declare one’s citizenship under oath, which makes the prosopography of the community even more difficult. The last chapter analyses the formation of a common judiciary field, able to function in times of strained relationship, through the presentation of bilateral procedures and of cases of conflict about tax exemptions, bankruptcy and reprisals

Burroughs, Van Stephan School of the Built Environment UNSW. "Quantitative criteria for the selection and stabilisation of soils for rammed earth wall construction". Awarded by:University of New South Wales. School of the Built Environment, 2001. http://handle.unsw.edu.au/1959.4/17861.

Testo completo
Abstract (sommario):
Modern building procedures and requirements demand that the selection and stabilisation of soils for the purposes of rammed earth construction be better quantified. This study examines the relationships between soil properties, stabiliser treatments, and stabilised strength and density for 111 soil samples taken from sites in New South Wales (Australia), and develops new quantitative criteria for soil assessment, selection, and stabilisation. Laboratory measurements of soil particle size distribution, plasticity, and shrinkage were made for each soil. Various quantities from 0-6 % of lime, cement, and asphalt were added to the soil samples, and the resulting 230 specimens were compacted, and cured for 28 days. Determinations were made of the optimum moisture content, maximum dry density, and compressive strength of the stabilised material. The samples showed stabilised strengths ranging from 1.0-5.4 MPa, with a mean of 2.62 MPa, and densities from 1.44-2.21 t/m3, with a mean of 1.86 t/m3. The results show that over 90 % of the variation in stabilised strength and density of the samples is due to variation in soil properties, with differences in stabiliser type or stabiliser quantity being relatively minor. The most important soil properties explaining stabilised strength are linear shrinkage and plasticity index. These properties have been used to categorise the soils into three groups on the basis of their suitability for stabilisation as measured against a compressive strength criterion of 2 MPa. Favourable soils have shrinkages of < 7.1 % and plasticities of < 16 %, and 90 % of these samples passed the 2 MPa criterion. Satisfactory soils have shrinkages of 7.1-13.0 % and plasticities of 16-30 %, and 65 % of these samples had strengths in excess of 2 MPa. Unfavourable soils have shrinkages of > 13 % and plasticities of > 30 %, and only 10 % of these samples exceeded the 2 MPa value. Soils in the favourable and satisfactory categories can be further discriminated using textural information. On that basis, all soils classified as favourable, and those classified as satisfactory and which also have sand contents < 60 %, are recommended as being suitable for stabilisation. Soils not fulfilling these criteria are unlikely to be successfully stabilised and should be rejected. These results stress the importance of selecting a soil favourably predisposed to stabilisation. Field techniques to search for such soils could be refined on the basis of the new soil criteria presented. Use of the criteria should also minimise unnecessary laboratory testing of the density and strength of soils that subsequently prove unsuitable for stabilisation. A flow chart is presented to guide practitioners through the different stages of soil testing, assessment, and rammed earth stabilisation.

Abstract (sommario):
Ma thèse, comprenant cinq chapitres et deux annexes, donne l’édition critique de la traduction latine du traité galénique De causis pulsuum réalisé par Burgundio de Pise (XIIe s.). Après un aperçu sur le texte grec et sur l’influence de la doctrine galénique du pouls en Occident dans le XIIe s., suit un profil de B. et l’introduction de la version latine, limitée aux livres III-IV (commentaire lemmatique au De pulsibus ad tirones). Une réflexion sur la méthode de traduction et sur les liens d’interdépendance entre ses versions de De causis et Ad tirones mène à une proposition de datation à l’intérieur de la chronologie relative des versions réalisées par B. A été ensuite confirmé philologiquement le rapport de dépendance entre la traduction et le texte grec du ms. Laur. plut. 74.18, dont est fourni une description complétée par l’analyse des notes de B. et de « B », collaborateur du scribe Ioannikios. Viennent ensuite la description rapide des vingt-cinq témoins latins et l’analyse du stemma de la tradition manuscrite. La thèse aboutit à l’édition critique, où le texte latin peut se lire avec la transcription du Laur. plut. 74.18 en regard (en apparat les variantes par rapport à l’édition de Kühn). L’édition critique est complétée par deux annexes : la première comprend les différences entre la traduction et le modèle grec et l’apparat critique exhaustif du latin ; la deuxième fournit un census des manuscrits et un texte de travail de la traduction du De pulsibus ad tirones avec la transcription du manuscrit grec modèle, le Laur. plut. 75.5. La thèse se termine avec les correspondances grecques-latines et latines-grecques du De causis pulsuum et du De pulsibus ad tirones
This dissertation consists of five chapters and two appendices and provides the critical edition of the Latin version of Galen’s treatise De causis pulsuum by Burgundio of Pisa (XII c.). After a general overview on the Greek text and on the impact of the galenic science of pulse in the West during the XII c., it follows the translator’s profile and an introduction to his version, limited just to the books III-IV (lemmatique commentary about the De pulsibus ad tirones). A reflection on the translator’s method and on the links of interdependence between his versions of De causis and Ad tirones leads to a dating proposal into the relative chronology of his work. Then, I was able to confirm the dependence of the Latin version from the Greek text of the ms. Laur. plut. 74.18, whose description is enriched with the analysis of the notes by B. and “B”, colleague of the scribe Ioannikios. Thereafter, it comes a brief description of the twenty-five Latin witnesses and the analysis of the stemma of the manuscript tradition. The dissertation culminates in the critic edition, in which the Latin text is in synopsis with the transcription of the Laur. plut. 74.18 (in apparatus the variants relative to Kühn’s edition). There are also two appendices: the first includes the differences between the translation and the Greek exemplar and the exhaustive apparatus of the Latin text; the second provides a census of the witnesses and a working text of the translation of the Ad tirones in synopsis with the transcription of the Greek exemplar, the Laur. plut. 75.5. The dissertation ends with Greek-Latin and Latin-Greek correspondances of the De causis pulsuum and the De pulsibus ad tirones

Abstract (sommario):
Ce travail est consacre aux elites de la commune de pise au xvie siecle, apres la fin de la republique de florence et l'installation des ducs de medicis a florence. Sous le regne des trois premiers grands-ducs, come 1er (1537-1574), francois 1er (1574-1587) et ferdinand 1er (1587-1609), les citoyens de pise doivent faire face aux exigences croissantes de l'administration florentine : surveillance de l'administration locale, controle des institutions pieuses, redefinition des taxes et des impots. Les notables de pise reussissent a maintenir de bonnes relations avec come 1er, qui promet a la ville une bienveillance particuliere et lui accorde graces et privileges. Il remet en fonction l'universite de pise, encourage le commerce et les manufactures, reorganise l'ufficio dei fossi. Les rapports entre la monarchie et les pisans se deteriorent sous le regne de francois 1er en raison des difficultes economiques. Ferdinand 1er, qui revient a la politique de come, se montre favorable a une entente avec les noblesses provinciales. Au cours du xvie siecle, les familles des honorables citoyens de pise se transforment en une veritable noblesse citadine. Elles redeploient une partie des capitaux investis dans les affaires en direction de la terre et renforcent leur possessions foncieres dans le contado pisano. L'entree dans les ordres de chevalerie de saint-etienne et de saint-jean de jerusalem apparait comme la voie d'anoblissement la plus sure. En mobilisant ses preuves de noblesse (arbres genealogiques, chroniques locales, armoiries), chaque famille s'efforce d'acceder a la dignite equestre. Lorsque le grand-duc reside a pise, les notables pisans, dont le statut nobiliaire est desormais reconnu, accedent a la cour et organisent en l'honneur du souverain des festivites comme le gioco del ponte
This work examines the pisan elite in the sixteenth century after the fall of the florentine republic and the establishment of the medicean duchy. The ruling group who possesses the full exercise of citizenship takes an active participation in the local magistracies as priors or reformators. Under the first three grand dukes, cosimo i (1537-1574), francesco i (1574-1587) and ferdinando i (1587-1609), this elite is faced with the increasing requirements of ducal administration : control over the priors' activities, supervision over the luoghi pii, strict laws on tax-exemptions. Nonetheless, the pisan notables succeed in keeping good relations with cosimo i, who has promised his personal protection to the fedelissima citta di pisa. He restores the university of pisa, encourages trade and manufactures, reorganises the magistracy of the ufficio dei fossi. Political relations between florence and pisa are much more difficult under francesco i because of the economic crisis of the 1580's. The third grand-duke ferdinando, who returns to the style of cosimo, pays more attention to provincial elites. In the last decades of the xvith century, the main pisan families lay claim to recognition as a noble group. The transformation of citizens into nobles gradually occurs through the end of the xvith and the beginning of the xviith century. Pisan notables become more sensitive to noble status their family life. Shifting investments from business to land, most families extend their property in thecontado pisano. The admission in the order of saint stephen and the order of malta appears as the best way to reach nobility. By exhibiting proofs of nobility such as genealogies, family trees, chronicles, coats of arms, every noble pisan family tries to gain the honor of becoming a knight. When the grand duke stays in pisa, pisan notables now appear as nobles, admitted to court and providing for such festivities as the gioco del ponte

Abstract (sommario):
Depuis 2001, l'OMS recommande l'utilisation des CTA pour traiter le paludisme simple, et, depuis 2006, la confirmation des cas par TDR. En théorie, 80% des malades doivent être traités par CTA et l'impact attendu est une diminution de la morbidité et mortalité palustres. L'objectif de nos recherches a donc été l'analyse de certains obstacles au succès de la mise en place des CTA, de faible recours des populations au système de soins publics, les écarts aux directives officielles dans les pratiques des soignants et l'observance partielle des malades. Ces obstacles ne sont pas spécifiques au Sénégal et se retrouvent dans d'autres pays subsahariens. A ce jour, 41 pays ont adoptés une CTA. Dans certains d'entre eux, une baisse de la morbidité et de la mortalité palustre a été documentée. Toutefois, il convient de regarder ces premiers succès avec prudence. En effet, il ne faut pas omettre l'impact majeur des autres stratégies de lutte. De plus, sur le long terme, bien que les CTA soient des traitements très efficaces, nous pensons que le contexte actuel de mise en place de ces traitements risque de compromettre leur impact. Afin de pérénniser les premiers succès, les interventions de soutien à l'introduction des CTA doivent améliorer l'accès à ces traitements et garantir leur utilisation correcte par les soignatns et les soignés. En outre, il est primordial d'adapter ces interventions aux considérations quotidiennes propres aux soignants et aux populations et les études à ce sujet devraient se poursuivre.

Abstract (sommario):
La plaine de Pise, située au nord-ouest de la Toscane, près du delta de l’Arno qui, après 241 km, se jette dans la mer Ligure à une faible distance du centre urbain de Pise. Différents processus géomorphologiques (érosion, transport, accumulation), principalement conditionnés par le système fluvial et marin (apport sédimentaire d’origine fluviale, formation du système deltaïque, progradation de la ligne de côte), ainsi que par les interventions humaines qui ensemble ont mené à sa configuration actuelle. L’abondance des ressources naturelles, en particulier des ressources en eau, la localisation géographique et l’accessibilité de la plaine sont quelques-uns des facteurs qui ont favorisé un occupation stable et durable depuis le Paléolithique inférieur. Les populations qui se sont succédées au cours des époques historiques ont néanmoins dû faire face au caractère changeant et dynamique de la plaine, et en particulier à la force de l’eau, qui a représenté une ressource inestimable ainsi qu’un imprévisible danger. Les recherches menées en particulier dans le cadre du doctorat se concentrent sur l’étude de deux phases historiques cruciales dans le processus de formation de la plaine de Pise : l’époque romaine et l’époque médiévale. Les interventions réalisées lors de la colonisation augustéenne (Ier siècle av. J.-C.) ont transformé la plaine, modifiant en profondeur le paysage rural par la mise en œuvre d’une nouvelle planification agraire, la centuriation de Pise, qui structure encore significativement le réseau hydraulique, le réseau routier et le système urbain. L’étude du processus de transformation et de transmission du réseau orthogonal nécessite une analyse approfondie des facteurs qui, au cours des différentes phases historiques, l’ont rendu “ visible ”, surtout pendant la période médiévale caractérisée par le “ retour ” d’un pouvoir centralisé, celui de la Commune de Pise, capable d’exercer un plus grand contrôle sur le territoire et les ressources hydriques. La recherche vise à reconstituer les principales caractéristiques et les différentes phases d’évolution du paysage centurié au cours des siècles, ce qui implique une étude approfondie des dynamiques paléoenvironnementales et paléohydrographiques qui ont affecté le contexte de Pise avant même la colonisation romaine.Pour obtenir les résultats attendues, une approche méthodologique interdisciplinaire et diachronique a été utilisée, capable de saisir les facteurs naturels et anthropiques qui, au cours des siècles, ont conditionné ce processus “ constructif ”. La lecture morphologique des parcelles urbaines et agraires a permis la reconnaissance des formes d’organisation du paysage de Pise, en particulier de la grille centuriée et des phénomènes de transmission et de déformation de ses éléments constitutifs. L’intégration des données stratigraphiques, enrichis par une campagne de carottages menée en 2016 en collaboration avec d’autres universités italiennes, aux résultats de l’étude historique-archéologique, archivistique et planimétrique, a permis d’obtenir de nouveaux résultats sur l’évolution pedosédimentaire et paléohydrographique de la plaine pisane étudié et de formuler des nouvelles hypothèses sur le scénario paléogéographique à l’époque romaine et son évolution pendant les siècles suivants.Les études de surface et de sous-sol ont ainsi permis de reconstituer la relation existante entre le systèmede peuplement, les formes d’exploitation et de gestion des ressources, les transformations paléoenvironnementales et paléohydrographiques et les dynamiques morphologiques (modalités de transmission et/ou de transformation de la trame centuriée) dans la longue durée, montrant que la centuriation visible dans sa version “ la plus actuelle ” est le résultat d’un processus long et continu d’interaction homme-environnement
The plain of Pisa, located in northwestern Tuscany, close to the Arno River’s delta, which flows into the Ligurian Sea near the town of Pisa after 241 km, is the result of different geomorphological processes (erosion, transport, accumulation). These are mainly conditioned by the fluvial and marine system (fluvial sedimentary accumulation, formation of the delta system, progradation of the coastline), as well as by human intervention, which together have led to its current formation. The abundance of natural resources, in particular water resources, the geographical location and the accessibility of the plain are some of the factors that have favoured a stable and lasting settlement since the Lower Palaeolithic. The populations that lived here over the course of the historical periods, however, had to face the changing and dynamic character of the plain, and in particular the force of the water, which represented an inestimable resource as well as an unpredictable danger. The research carried out during this PhD particularly focuses on the study of two historical phases that were crucial in the formation of the Pisa plain: the Roman and the medieval periods. The interventions carried out at the time of the Augustan colonization (I century BC) transformed the plain, impacting the rural landscape through the construction of a new agrarian system or the centuriation of Pisa, which still significantly structures the hydric network, the road network and the settlement system today. The transformation and transmission process of the orthogonal grid requires a developed analysis of the factors that have made it “visible” during different historical phases. This is especially true for the medieval period, which is characterised by the “return” of the Municipality of Pisa, a centralised power that was able to exercise greater control over territory and water resources. This research aims to reconstruct the main characteristics and the different evolutionary phases of the centuriated landscape over the centuries through the study of the palaeoenvironmental and palaeohydrographic dynamics that have affected Pisa even before Roman colonization.An interdisciplinary and diachronic methodological approach was applied in order to best identify and understand the natural and anthropic factors that have conditioned this “constructive” process over time. The morphological analysis of the urban and agrarian parcels allowed the recognition of the organisational forms of the Pisan landscape, in particular of the centurial grid and the phenomena of transmission and deformation of its constituent elements. The integration of the stratigraphic database (enriched by a coring campaign carried out in 2016 in collaboration with several Italian universities) with the historical-archaeological, archival and planimetric data has made it possible to obtain new results on the pedosedimentary and paleohydrographic evolution of the Pisan plain. It has also permitted us to propose new hypotheses on the paleogeography of the Roman period as well as its evolution over the centuries.Surface and subsoil surveys have made it possible to reconstruct the relationship between the settlement system, the forms of exploitation and management of resources, the palaeoenvironmental and palaeohydrographic transformations and the morphological dynamics (modes of transmission and/or transformation of the centurial grid) over the long term, demonstrating that the visible centuriation in its “most updated” version is the result of a long and continuous process of human-environment interaction

Abstract (sommario):
Pendant la Grande Guerre (1914-1918), les évêques des Pays belligérants décidèrent de soutenir la cause nationale, en disant que la victoire de la patrie était nécessaire en vue du retour à la paix et à la vie chrétienne prêché par le souverain pontife. Ce travail vise à éclairer le discours et l'action de deux cardinaux devenus dans ces années-là des symboles de l'harmonie entre foi et patriotisme: Mgr Pietro Maffi, archevêque de Pise, et Mgr Léon-Adolphe Amette, archevêque de Paris. La thèse est divisée en quatre parties. La première est consacrée au rapport des prélats avec la modernité issue de 1789 et à leurs efforts pour faire redevenir chrétienne la société, en utilisant le culte des saints, la science, le mouvement politique et le nationalisme catholiques. La deuxième partie s'occupe des années 1914-1918, pendant lesquelles Maffi et Amette se conduisirent en alliés des autorités civiles, en dépit des graves tensions entre le Vatican et les gouvernements nationaux. La troisième et la quatrième partie expliquent comment la guerre fut commémoré par les cardinaux et, après leur mort, par les collaborateurs, les amis et les successeurs, qui soulignèrent toujours la loyauté des catholiques à l'État. Certes extrême (l'épiscopat européen ne fut pas toujours chauvin), le cas de Maffi et Amette permets d'étudier le mélange entre religion traditionnelle et religion patriotique qui fut parmi les causes de la résistance aux deuils et aux sacrifices typiques de la guerre totale
The bishops of the countries involved in World War I (1914-1918) chose to stand on their country's side, stating that military victory was necessary to end the conflict and to get back to a christian way of life, as the Pope wished. This work aims at explaining the behaviour of two cardinals who became in those years symbols of the harmony between religious faith and patriotism: the archbishop of Pisa Pietro Maffi and the archbishop of Paris Léon-Adolphe Amette. The thesis is divided in four sections. The first one is dedicated to the way the bishops dealt with the modernity arisen from 1789 and to their efforts to recreate a christian society through the saints' cult, catholic science, political organisation and nationalism. The second section focuses on 1914-1918, when Maffi and Amette openly supported the political authorities of their countries despite the tension between these ones and the Vatican. The third and the fourth section are dedicated to the war memory, celebrated by the bishops – and after their death by their assistants, friends and successors – to stress the catholics' loyal attitude towards the State. Although extreme (the european episcopate was not always chauvinist), Maffi and Amette's case sheds light on the mixture between catholicism and the patriotic religion that was among the causes of the resistance to the sufferings and sacrifices typical of the total war

Guiron le courtois—a vast chivalric novel written in prose and composed of the Roman de Meliadus and of the Roman de Guiron—was copied, redrafted, compiled in various manuscripts since its creation spanning from 1235-1240 to the end of the Middle Ages. Its material allows all kinds of continuations which makes it a work with blurred outlines. The manuscript BnF fr. 340 (End of 14th-Beginning 15th Century) associates the Roman de Meliadus and the Compilation of Rusticien de Pise; it forms a whole in which can be seen wandering knights, namely the fathers of the great Arthurian heroes driven by violent fights and a desire to shed blood abundantly, but also by merry encounters and word exchanges. This thesis ends at analysing this lively community through the exploration of both text and imagery in the manuscript BnF Fr 340; this iconographic analysis leads to the study of new programs of manuscripts dating back to the same period

Abstract (sommario):
Résumé : Contexte : L'évaluation des besoins est indispensable à l'élaboration d'un plan d'aide chez les personnes âgées ou handicapées. En France, des changements législatifs laissent entrevoir une harmonisation des pratiques d'évaluation. Le Conseil général de Dordogne a donc décidé d'innover en implantant le SMAF et l'outil informatisé eSMAF dans 11 établissements du secteur médico-social. Le projet s'est déroulé d'octobre 2008 à septembre 2010. Objectifs : Cette étude d'implantation poursuivait trois objectifs : 1) mesurer le degré de mise en oeuvre du SMAF et de ses composantes informatisées; 2) identifier les ajustements faits durant la phase d'implantation et 3) identifier les conditions qui favorisent ou limitent l'utilisation du SMAF. Méthodologie : Le devis de recherche a été élaboré à partir d'un modèle logique adapté intégrant les facteurs stratégiques, organisationnels et individuels pouvant influencer le projet. Une approche par étude de cas associant une méthode mixte pour le recueil des informations et une approche déductive pour l'analyse des données furent utilisée. Le niveau de mise en oeuvre a été mesuré en continu durant la fenêtre d'observation. Les ajustements faits au cours de l'implantation ont été répertoriés. Des entrevues de groupe ont été réalisées avec les intervenants évaluateurs de chaque établissement avant et après l'utilisation du SMAF. Des entrevues individuelles ont été faites avec les acteurs stratégiques et les directions des établissements au terme du projet. Résultats : Au total, 34 des 39 intervenants formés au SMAF ont réalisé des évaluations. Durant la fenêtre d'observation de cinq mois, 1,189 évaluations SMAF sur 2,260 évaluations attendues ont été réalisées. Les services d'aide à domicile ont mis cinq mois supplémentaires pour évaluer tous leurs usagers (n =1536). Un Tableau d'aide individualisé et le Profil Iso-SMAF de chaque usager ont été produits. Les ajustements faits durant l'implantation concernent principalement l'assistance informatique et le soutien clinique. Des facteurs stratégiques, organisationnels et individuels expliquant le niveau d'adhésion des acteurs et le déroulement de l'implantation ont été identifiés. Conclusion : Le SMAF a été implanté avec succès dans les établissements. Au terme du projet, un plan d'action pour l'implantation du SMAF et du eSMAF dans des milieux similaires a été proposé.||Abstract : Background : An evaluation of needs is essential to develop a plan to help the elderly and handicapped people. In France, legal changes suggest harmonization of evaluation practices. The Dordogne General council decided to innovate by implementing the SMAF and the computerized tool eSMAF in 11 organisations of the community health sector. The project took place from October 2008 to September 2010. Objectives: The study pursues three goals: 1) to measure the degree of implementation of the SMAF and its computerized components; 2) to identify the adjustments made during the phase of implementation and 3) to identify the conditions that support or limit the use of the SMAF. Methods: The research design was developed from a logic model incorporating the strategic organizational and individual factors that could influence the project. A case study approach involving a mixed method or collecting information and deductive approach to data analysis were used. The level of implantation was measured continuously during the observation window. Adjustments made during implantation were identified. Focus group interviews were conducted with participants from each institution before and after using the SMAF. Individual interviews were conducted with strategic actors and institution's directors at the end of the project. Results: In total, 34 of the 39 SMAF-trained people conducted evaluations. During the evaluation period of five months, 1.189 out of the 2,260 expected SMAF assessments were carried out. The services of home assistance took five extra months to assess all their users (n = 1536). A synthesis of individualized assistance required and Iso-SMAF individual user's profile was produced. Adjustments made during the implementation mainly concern computer assistance and clinical support. Strategic, organizational and individual factors explaining the level of adhesion and the progress of implementation were identified. Conclusion: The SMAF has been successfully implemented in the targeted institutions. At the end of the project, a plan for implantation of the SMAF and eSMAF in similar environments was proposed.

Abstract (sommario):
Piles are often used to resist vertical and lateral loads when shallow foundations are inadequate or uneconomical. A critical part in designing pile foundations is the pile-to-cap connection. When a moment resisting connection is desired, reinforcement is typically used between the pile and the cap. A pile-to-cap connection with sufficient pile embedment depth, however, may provide similar results. One model that is currently used to determine the capacity of a pile-to-cap connection was developed by Marcakis and Mitchell for steel members embedded in concrete. This model considers an embedment mechanism that resists rotation at the connection. Recent testing has shown, however, that this model is conservative and that additional mechanisms contribute to the strength of the connection. An experimental study was conducted to investigate pile-to-cap connections for pipe piles without reinforcement. Three pile-to-cap specimens with varying pile embedment depth were loaded laterally to failure. The results from the testing confirm that pile-to-cap connections with shallow pile embedment depth have significant stiffness. An improved model was developed to estimate elastic and ultimate capacities of embedded connections. In addition to the embedment mechanism used by Marcakis and Mitchell, this model includes a bearing mechanism at the end of the pile. For pile-to-cap connections with a large pile bearing area to pile embedment depth ratio, this bearing mechanism provides more strength than the embedment mechanism. For pile-to-cap connections with a small pile bearing area to pile embedment depth ratio, this bearing mechanism has little contribution to the strength of the connection.

Abstract (sommario):
Slash pile burning is the most common method of forest residue disposal following ponderosa pine restoration harvests, which are intended to reduce the risk of catastrophic fire and restore the historical structure and function of forests in western Montana. The impact of high-intensity, long-duration fire (pile burning) on soil processes and plant community dynamics is not well understood. The objectives of this study were: (1) to characterize the influence of slash pile burning on soil nutrient availability, soil microbial activity, and arbuscular mycorrhizal (AM) infection; (2) to compare seeding and soil amendment effects on burn scars. In May 2006, slash piles were burned in a ponderosa pine stand near Florence, Montana and 45 scars were sampled. Soil samples were collected from three locations in each slash pile to a depth of 10 cm and characterized for available soil NH4 +-N, NO3 - -N, potentially mineralizable nitrogen (PMN), and total C and N, water-soluble PO4 3- -P, microbial biomass, and mycorrhizal inoculum potential (MIP). In the burned center, soil NH4 +-N was greatest one month post-burn and remained elevated one year later. There was no observable increase in NO3 - -N until one year post-burn. Soluble PO4 3- -P was not impacted by burning. Microbial biomass was reduced by burning and did not recover one year later. Pile burning greatly reduced MIP. In October 2006, fire scars were either seeded with native graminoids or left non-seeded, divided into subplots, and assigned to one of five treatments: control, addition of local organic matter, scarification, scarification and organic matter addition, or scarification and commercial compost addition. Soils were monitored for the previously measured soil parameters and resin-sorbed inorganic N. Scarification with organic matter amendment and scarification with compost amendment both ameliorated soil properties. Seeding most effectively increased plant cover and suppressed non-native invasive species, while scarification or scarification with organic matter amendment further improved early plant establishment. Collectively, these data help characterize the impacts of slash pile burning as a management technique in ponderosa pine forests and illustrate potential treatments for restoring burn pile scars.

Abstract (sommario):
Les faisceaux d’ions de l’ordre du MeV permettent la mise en œuvre de techniques d’analyse tant élémentaire (Ion Beam Analysis-IBA) que moléculaire (Time of Flight Secondary Ion Mass Spectrometry) pour des matériaux solides peu étudiés en raison de leur hétérogénéité: les mélanges de poudres. La première partie de notre travail est à placer dans le contexte de l’étude de la photodégradation des pesticides dans l’environnement à travers l’analyse ToF-SIMS de pesticides imprégnés dans des sols naturels. A partir d’une étude comparative du phénomène induit sur des dépôts sur des substrats homogènes nous présentons les résultats de la cinétique de dégradation pour plusieurs pesticides avec en particulier des valeurs de demi-vies. La seconde partie s’inscrit dans le processus de contrôle de produits pharmaceutiques commerciaux à analyser en l’état. Nous montrons que la quantification du principe actif (p.a.) en présence d’excipients est possible: -par les techniques IBA quand le p.a. contient des hétéroatomes non présents dans les excipients. La précision (<7%) est alors la plupart du temps bien meilleure que les exigences du contrôle industriel. -par la technique ToF-SIMS dans tous les cas mais dans des domaines définis par les courbes d’étalonnage pour avoir les meilleures sensibilités. Ces restrictions dépendent de la nature des partenaires (p.a. et excipients) et mettent en évidence des effets de matrice dont l’étude doit permettre l’amélioration de la préparation de tels échantillons en vue d’analyses plus performantes. Ces techniques dont les avantages et les limitations sont discutés, sont à notre connaissance utilisées pour la première fois sur de tels matériaux « réels »
The aim of this study is to analyze heterogeneous organic matter by exhibiting analytical difficulties by classical techniques under solid state. The first part of this work is dedicated to the study of pesticides photodegradation impregnated in soils by ToF-SIMS technique. A comparative investigation of the induced phenomenon obtained with the same pesticides deposited as thin layer on a neutral support helped in studying the degradation kinetics of those pesticides especially their half-lives. The second part is dedicated to the development of new analytical method for the analysis of commercialized pharmaceutical compounds without prior sample preparation. We have demonstrated the possibility of active ingredient (A.I.) quantification in the presence of the excipients by the following analytical techniques: IBA techniques if the A.I. contains an heteroatom, however, absent in the excipients. The precision (< 7%) is found to be in the majority of the studied cases within the analytical standards of the quality control processes. ToF-SIMS technique for all drugs however within a specific range of concentration defined by the calibration curves for improved sensitivities. These restrictions in the dynamic concentration range depend on the nature of the mixtures A.I. / Excipients on hand and show evidence of the matrix effect on the other hand. A deep investigation on the matrix nature should improve the sample preparation method for more performance analysis. To our knowledge, it is the first time that the above mentioned techniques whose analytical advantages and limitations have been discussed were applied to such solid matrix samples

Abstract (sommario):
This thesis is a theoretical study, using both finite element and boundary element methods, of the behaviour of single-piles and pile groups under vertical and lateral loading. It offers an improved understanding of the soil-structure interaction that occurs in pile groups, particularly closely spaced piles subjected to lateral loads. The potential of a two- dimensional idealisation of what is a three-dimensional problem is demonstrated by achieving real insight into the complex nature of pile-soil and pile-soil-pile interaction in pile groups. A new load transfer mechanism is presented for a rigid, axially loaded vertical pile. From this an improvement is then derived to the analytical solution for pile head settlement given by Randolph and Wroth (1978). The improved mechanism has the further merit that it can be applied also to solutions for flexible piles and pile groups. The improved analytical solution is further adapted in the development of two correcting layers specifically for vertically loaded piles to model infinite boundaries in the finite element model. The correcting layers help in establishing superiority of the finite element method over the boundary element method. To model pile-soil interaction, a purely cohesive interface element is developed and then validated by performing various two-dimensional test problems, including stability analysis of flat surface footings. Footing-soil interface tension is successfully modelled in this way - an outcome that entails a significant modification to the Hansen (1970) bearing capacity solution. Stability analysis is also carried out of conical footings using a three-dimensional finite element model: the results help to explain the applicability of the existing bearing capacity theories to conical footings. The ultimate lateral soil reaction is determined and various pile loading stages are investigated through parametric studies. Study of the stage immediately following pile installation (i.e. the consolidation stage) highlights the need to develop an effective stress analysis for laterally loaded piles. Pile-soil interaction is studied using the cohesive interface element presented earlier, which proves to be quite successful in smoothing out the stress discontinuities around the pile. A new material model for frictional soils is presented, and validated by using it to model an extension test: it captures well post-peak behaviour and takes care of the effects of dilation on the response of laterally loaded piles. Finally, mechanisms of interaction in closely spaced pile groups are studied. Simple analytical expressions are derived which quantify the effects of interaction. A new method of analysis is presented for single-piles and pile groups which offers a considerable degree of reliability without having to do either impossibly expensive full scale field tests or prohibitively expensive full three-dimensional analysis using the currently available computers.

Abstract (sommario):
This study has been done in order to examine which type of pile, pile driving- and waterproofing methodsare most suited for an existing building. A building that will undergo an extensive reinforcement of itsfoundation.The study has been made in regard to the following conditions:● Different types of clay soil (Cohesion soil)● Underlying rock structure with heavy incline (8° slope)● Sensitive environment for vibrations and ground displacements● Limited accessibility (Room and maximum weight)● Compressive and tensile forces● Pool (Water environment)To answer the questions of statement a scientific literature study, interview with a foundation expert,calculations in sizing, but also time and cost analysis has been conducted. A site visit to an object ofreference, Nya Krav Himmerfjärdsverket, occurred where a reconstruction of an existing building withextensive work of reinforcement to its’ foundation was in progress.The steel pipe pile with anchor and steel core pile are the best pile types in such conditions as compressiveand tensile forces, clay soil with underlying inclined rock bed, limited accessibility and sensitivesurrounding environment. Which pile type, pile driving- and waterproofing methods that are most suited forsuch conditions is different for each project. The steel core pile is more suitable for higher loads, rockstructures in incline and when verification of load capacity is not needed. At the same time the steel pipepile is more suited when the underlying rock bed is far below ground level, where you would need manypile elements and joints. In addition, the steel pipe pile is suitable for buildings with a complex loaddistribution, where a greater number of piles with lower load capacities is needed in order to satisfy this.The best pile driving method for drilling in sensitive environment is the water equipped down-the-hole(DTH) drill. This drilling method is gentle to surrounding piles in existing building.In order to minimise the risk of water penetration and then expand the life span of the construction, use ofa combination of different waterproofing systems is to prefer when waterproofing pile heads or pilefoundations.

Abstract (sommario):
Due to the recent raise of oil price, giant oil and gas companies have expanded their exploration to more than 3 kilometres under see level. In extreme conditions of deep under water excavation, pipe-in-pipe systems have become favourable option due to their unique structural capacity. Subsea pipelines and PIP systems experience large bending moments during installation and operation. However, unlike single-walled pipelines, the behaviour of PIPs under bending has been only marginally addressed. In this project, the bending response of the PIP systems with diameter-to-thickness ratio (D/t) of 15 to 40 is investigated. To this purpose Linear bifurcation analyses (LBA) and geometrically nonlinear analyses (GNA) are conducted on PIPs of varying lengths. For the first time, closed formed analytical solution are derived and provided to predict the classical and nonlinear limit moments of PIPs, and are compared to the existing expressions for single-walled pipelines. Ultimate bending moments of PIPs are obtained from physical four-point bending tests and are compared against geometrically and materially nonlinear analyses (GMNA). The finite element results show that in PIPs with centralizers, the limit moments (GNA) drop slightly, however, the ultimate moments (GMNA) remain unchanged. A parametric study of the effect of geometry and material properties of the inner and outer pipes on the ultimate moment of PIPs is presented. It is understood that the ultimate moments of PIPs with thick tubes are predominantly influenced by the material nonlinearities rather than ovalization of the tubes. Moreover, to investigate effect of external pressure on the bending moment capacity of PIPs, Finite Element study has been performed on a PIP system subject to pure bending, pure external pressure and combined actions of external pressure and bending. Results show that bending moment capacity of the PIP systems are more susceptible to the external pressure compared to that of the same single outer pipes.

Testo completo
Abstract (sommario):
In an effort to obtain 100-year level hurricane protection for southeastern Louisiana, the U.S. Army Corps of Engineers (USACE) has implemented design guidelines that both levees and structures shall be designed to. Historically, USACE has used concrete piles or steel H-piles as the foundations for these structures. Because of the magnitude of obtaining 100-year level hurricane protection, limited resources, and a condensed timeline, spiral welded pipe piles can be manufactured as an alternative to either the concrete piles or steel H-piles. This research will provide the necessary background for understanding pile foundations, will compare the behaviors of spiral welded pipe piles to that of other piles with respect to geotechnical concerns through a series of pile load tests, and will offer a current cost analysis. This background, testing, and cost analysis will show that spiral welded pipe piles are a viable alternative for USACE structures from a geotechnical and economic perspective.

Russell, Dalin Newell. "The Influence of Pile Shape and Pile Sleeves on Lateral Load Resistance". BYU ScholarsArchive, 2016. https://scholarsarchive.byu.edu/etd/6232.

Testo completo
Abstract (sommario):
The lateral resistance of pile foundations is typically based on the performance of round piles even though other pile types are used. Due to lack of data there is a certain level of uncertainty when designing pile foundations other than round piles for lateral loading. Theoretical analyses have suggested that square sections will have more lateral resistance due to the increased side shear resistance, no test results have been available to substantiate the contention. Full-scale lateral load tests involving pile shapes such as circular, circular wrapped with high density polyethylene sheeting, square, H, and circular with a corrugated metal sleeve have been performed considering the influence of soil-pile interaction on lateral load resistance. The load test results, which can be summarized as a p-y curve, show higher soil resistance from the H and square sections after accounting for differences in the moment of inertia for the different pile sections. The increased soil resistance can generally be accounted for using a p-multiplier approach with a value of approximately 1.25 for square or 1.2 for H piles relative to circular piles. It has been determined that high density polyethylene sheeting provides little if any reduction in the lateral resistance when wrapped around a circular pile. Circular piles with a corrugated metal sleeve respond to lateral loading with higher values of lateral resistance than independent circular piles in the same soil.

Abstract (sommario):
The focus of the current project was to establish an improved and reliable protocol for somatic embryogenesis in 1) Pinus taeda and Pinus palustris; pine species of high value for commercial applications and germplasm conservation supported through breeding programs at The Virginia Department of Forestry (Chapter III); and 2) Pinus oocarpa; an economically important pine species in the southern half of Mexico and Central America (Chapter IV). In addition, 3) the study of the gene expression analysis of developmental stages of both somatic and zygotic embryos of P. taeda was compared to assess developmental fidelity at the molecular level (Chapter V). By testing four basal media combined with different plant growth regulator combinations, we have established stable embryogenic cultures from high value families of P. taeda and P. palustris using the tissue culture medium 1218 (Pullman et al 2005) in combination with an auxin:citokinin ratio at 10:5 (molar). However, optimization of the protocols for the maturation and further conversion of somatic embryos to seedlings requires further work. For P. oocarpa, we hypothesized that somatic embryo induction may be possible by mimicking natural seed-embryo developmental conditions, and a new tissue culture medium, based on the mineral content of the seed nutritive tissue (megagametophyte), was formulated. The novel culture medium (PO) was tested in combination with different plant growth regulator concentrations for the initiation of somatic embryogenesis from fresh collections of P. oocarpa immature zygotic embryos. Additionally, the established embryogenic cultures were able to mature and germinate, to our knowledge resulting in the first report of the production of P. oocarpa plantlets through somatic embryogenesis. PO medium also has the potential to be used successfully for other tropical pine species which today suffer from suboptimal somatic embryogenesis protocols. The fundamental study of molecular regulation of embryo development showed that under the current maturation conditions, P. taeda somatic embryos were temporally similar in gene expression to zygotic embryos of the same species. However, potentially important differences were found and results could potentially explain the low germination success during somatic embryogenesis. More research is still needed to further explore the natural environment of developing seed embryos to improve the somatic embryogenesis protocols and to enable full integration of this clonal propagation method into the breeding programs for pines.

Testo completo
Abstract (sommario):
Whitebark pine (Pinus albicaulis Engelmann) is a treeline species in the central Rocky Mountains. Its occupation of high elevations previously protected whitebark pine from long-term mountain pine beetle outbreaks. The mountain pine beetle, however, is currently reaching outbreaks of record magnitude in high-elevation whitebark pine. We used a factorial laboratory experiment to compare mountain pine beetle (Dendroctonus ponderosae Hopkins) life history characteristics between a typical host, lodgepole pine (Pinus contorta Engelmann), and whitebark pine. We tested the effects of natal host and brood host on beetle fecundity, offspring size, and brood sex-ratio. We reared mountain pine beetles from whitebark pine and from lodgepole pine, and infested half of them into their natal host and half into the other host. Fecundity was greater overall in lodgepole pine brood hosts. Among lodgepole brood hosts, beetles from whitebark pine had greater fecundity. Fecundity was also significantly related to phloem thickness, which was greater in lodgepole pine. Offspring were larger from whitebark brood hosts than from lodgepole, regardless of their parents’ natal host. Finally, sex-ratio was closer to 1:1 in lodgepole than in whitebark brood hosts. We conclude that host species affects life history of mountain pine beetle with consequences for individual beetle fitness.

Abstract (sommario):
La méthode proposée présente une analyse simple de l’interaction sol-structure (SSI) pour le calcul des pieux sous sollicitation axiales, transversales et groupe de pieux. Un modèle basé sur le concept de macroéléments, s'inspire de Abboud 2017, est développé pour étudier le SSI en prenant en compte les différentes non-linéarités. Sa formulation est basée sur la théorie de l'élastoplasticité et s'inspire des normes européennes (Eurocodes 7 et 8). Les différents paramètres étant définis à partir d'essais en laboratoire ou in situ, ou à partir de simulations numériques dans des conditions statiques. Ce modèle réduit les coûts de calcul car les non-linéarités liées au SSI sont concentrées dans des points particuliers du modèle de calcul. L'avantage du macroélément réside dans sa formulation en forces et déplacements, ce qui facilite son utilisation pour la justification des fondations (capacité portante, glissement, détachement, tassement, translation, distorsions et rotation). De plus, ce macroélément est implémenté dans le cadre de la méthode des éléments finis en tant que fish function dans Flac3D. Cet outil est capable de simuler le SSI du chargé monotone appliqué verticalement et transversalement au pieu. Le modèle proposé a été validé par les résultats des tests de charge de pieu, la méthode des courbes de transfert (basée sur la méthode de Frank et Zhao) et la programmation informatique (conventionnels Flac3D et Pilate). L'approche réussit avec une bonne performance. De plus, l'efficacité et l'application pratique des cette methode dans l'analyse par éléments finis de calcul sont réalisables pour un pieu et un groupe de pieux
The proposed method presents a simple analysis of Soil-Structure Interaction (SSI) for deep foundation under static load that is applied for single pile and pile group. A model based on macroelement concept, inspired from Abboud 2017, is developed to study the SSI taking into account the different nonlinearities. Its formulation is based on the theory of elastoplasticity and is inspired by European standards (Eurocodes 7 and 8). Wherein, the different parameters are defined from laboratory or in situ tests, or from numerical simulations under static conditions. This model reduces computational costs because the nonlinearities related to the SSI are concentrated in particular points of the computation model. The advantage of macroelement lies in its formulation in forces and displacements, which facilitates its use for the justification of the foundations (bearing capacity, sliding, detachment, settlements, translations, distortions and rotations). Furthermore, this macroelement is implemented in a Finite Element Method framework as a fish function in Flac3D. This tool is capable of simulating the SSI in the monotonic loaded pile. The proposed model has been validated with pile load test results, load transfer method (based on Frank and Zhao method) and computer programming (conventional Flac3D and Pilate). The approach succeeds with a good performance. Additionally, the efficiency and practical application of this method in the computation finite-element analysis are feasible for Single Pile and Pile Group

Abstract (sommario):
La thèse est consacrée à l'institution médièvale des juges sardes crée au Vie siècle par l'empereur romain Justinien, dans le but de comprendre s'ils furent des souverains. L'étude de l'histoire de cette forme de pouvoir montre en fait une remarquable continuité depuis l'Antiquité, le pape ayant remplacé à la fin du XI ème siècle l'empereur byzantin et le roi d'Aragon s'étant substitué au pape à la fin du XIII ème siècle. Même si pendant quelques décennies entre le milieu du XI ème et le milieu du XII ème siècle, les juges revendiquent la titulature royale, ils exercent en fait toujours leur pouvoir comme un office au nom d'un pouvoir souverain extérieur. Or, le caractère "extérieur" de ce pouvoir suprême est précisément ce qui a permis au juge du haut Moyen Âge, puis aux juges postérieurs, d'exercer pleinement leur pouvoir dans leur territoire et d'y apparaître presque comme des rois pendant près de sept siècles. Cependant la centralisation étatique, qui caractérise les monarchies occidentales à partir du XIVe siècle, ne pouvait que se heurter à cette autonomie de facto. Le système des judicats était dès lors condamné, mais son legs principal, la création d'une "identité sarde", fut fondé sur une idéalisation du passé qui attribuait une pleine souveraineté aux juges et une totale indépendance aux judicats
The thesis is devoted to the Sardinian medieval institution of the Iudices (Judges) created in the sixth Century by the Roman Emperor Justinian, in order to understand if they were sovereign. The study of the history of this form of power, in fact, shows a remarkable continuity since ancient times: at the end of the eleventh century the pope replaced the Byzantine emperor, and in the late thirteenth century the king of Aragon substituted the Pope. Although for several decades between the mid-eleventh to the mid twelfth century, the judges claimed the royal title in fact they always get their power as an office on behalf of a sovereign power outside. However, the "outside" character of this supreme power is precisely what has allowed the judge of the High Middle Ages, then after the judges to exercise their full authority in their territory and to appear almost like kings for nearly seven centuries. However, the state -centralization, which characterizes the western monarchies from the fourteenth century, could only come up with this de facto autonomy. The system of the Iudicati was therefore condemned, but his main legacy, the creation of a "Sardinian identity", was based on an idealization of the past which gave full sovereignty to the judges and full independence to the ludicati

Abstract (sommario):
La pile à combustible PEMFC est un convertisseur d'énergie qui présente des avantages indéniables pour faire partie des solutions mises en œuvre pour assurer un mixte énergétique décarbonné. Les nombreux auxiliaires du système de la pile génèrent des perturbations qui sont responsables directement ou indirectement des conditions défavorables sur le cœur de pile. Les performances et durée de vie de la pile peuvent être impactées. Dans l'objectif d'améliorer la co-conception de la pile avec son système, les interactions entre deux groupes du système et la pile sont étudiées dans ce travail : les interactions entre le groupe air et le cœur de pile. En particulier, l'étude s'est focalisée sur l'impact d'un fonctionnement en sous stœchiométrie en oxygène sur la performance et la durabilité de la pile et sur l'évolution des conditions locales du cœur de pile. Le couplage des différents essais expérimentaux (mesures de densité de courant, tests de vieillissement, études post-mortem) avec le modèle dynamique 2D a permis de mettre en évidence différentes zones de fonctionnement dans la pile. En effet, en entrée cathodique, durant un appauvrissement en oxygène, l'augmentation de la densité de courant peut devenir très importante impliquant une modification des conditions locales qui peuvent être très néfastes pour la pile. les interactions entre le convertisseur statique électrique et le cœur de pile. Plus particulièrement, les conséquences des oscillations de courant hautes fréquences générées par le convertisseur DC/DC sur la durabilité de la pile ont été étudiées. Des essais spécifiques de vieillissement longue durée ont permis de mettre en évidence une interaction entre les oscillations de courant et les dégradations réversibles de la pile.

Pine bark beetles in Arizona are generally of the genus Ips or Dendroctonus. Fading foliage in the tree is often the first sign of a beetle attack. Prevention is best practiced since control is not possible once the beetles have successfully colonized the tree. Colonization is dependent upon trees being in a vulnerable condition caused by stress from various agents and site conditions.

Essa dissertação trata de aspectos do funcionamento da leitura em sala de aula de ciências, a partir de três textos do campo da ciência e da tecnologia, veiculados pelo Programa Internacional de Avaliação de Estudantes (PISA) objetivando compreender que sentidos sobre Ciências e Tecnologias são produzidos pelos estudantes. Analiso as condições de produção da leitura e dos discursos envolvendo esses textos, em situações de sala de aula, na escola fundamental, na disciplina de ciências. Para tanto, realizo uma pesquisa de cunho qualitativo, adotando como suporte teórico-metodológico a Análise de Discurso (AD) de linha francesa, com destaque para as questões que envolvem a linguagem do/no ensino de ciências, em particular, o que se refere à produção de sentidos sobre ciências e tecnologias em situação de sala de aula de ciências. Nessa perspectiva discursiva a linguagem é compreendida como não transparente, pois os sentidos para um texto não são dados e nem estão à espera de serem descobertos, pois estes são construídos pelos leitores dependendo das condições de produção dessas leituras. Dessa forma, a leitura dos textos do PISA vai além da mera decodificação de palavras e imagens. Assim, foi possível perceber na leitura dos estudantes uma relação entre paráfrase e polissemia envolvendo os sentidos sobre ciências e tecnologias. Com essa pesquisa pretendo produzir uma perspectiva crítica diante dos temas dos textos e da própria avaliação do PISA; contribuir para um ensino de ciências menos neutro e passivo diante das questões científicas e tecnológicas; incluir entre as discussões para o ensino de ciências, as questões de linguagem; colocar em pauta as interpretações possíveis para os textos do PISA e a partir daí discutir as implicações dessa perspectiva de linguagem em processos avaliativos como esse

Abstract (sommario):
The performance, strength and ductility of prestressed concrete piles, and their connection to pile caps, subjected to severe seismic loading are investigated in this thesis. Knowledge of the strength and ductility of the pile within its embedded length in the foundation material is of importance due to the large deformations which can occur during an earthquake, particularly at the interface of hard and soft layers of foundation material. Connection details are of interest since high moments, shears and axial forces need to be transferred to pile caps during earthquake loading. Two series of tests of piles and their connections, and accompanying analyses, were conducted. Design tables and charts were derived. The first test series consisted of six full scale octagonal prestressed concrete piles, confined spirally with either Grade 275 steel or hard drawn (Grade 485) steel wire and having various confinement levels, tested under axial load and cyclic flexure. Results of the theoretical analysis were compared with the experimental data. It was found that properly detailed prestressed concrete piles without additional nonprestressed longitudinal steel can sustain large displacement ductility factors without losing their lateral load carrying capacity significantly if confined according to full ductility. The second test series consisted of six full scale octagonal piles connected to full scale reinforced pile caps. The piles were either fully or partially prestressed. Three types of pile to pile cap connection were investigated, namely the precast embedded type, the stripped pile head type, and the type where steel dowel bars are used as the connection device. Theoretical analyses were used to compare the experimental data. The connection details investigated were found to give satisfactory performance. Finally, tables and charts obtained for the pile properties are presented for design purposes. The design tables are used to assess the enhancement factors of pile cross sections within the length or at the interface of the connection at the pile cap. The design charts are used to calculate the yield curvatures as well as the available curvatures and available curvature ductility factors. Recommendations for future research are proposed to complement the work already done up to this stage.

Abstract (sommario):
The problem of water loss from water distribution systems is an issue that faces municipalities worldwide. A large proportion of water loss is a result of leakage. With increasing water scarcity across the globe, it is imperative to conserve water resources, and hence reduce leakage in water distribution systems as best we can. Leaks develop in various different forms, and they form in pipes of all materials. It has been observed in numerous cases around the world that pipe material has been removed from the pipe surfaces adjacent to leaks in excavated failed water distribution pipe specimens. It was proposed by various researchers that this pipe material was being removed as a result of abrasive soil action caused by the pipe leak itself. When pressurised water distribution pipes fail, they emit high velocity jets of water into the surrounding soil bed. Research has shown that high velocity jets of water entering a granular soil bed have the ability to fluidise the bed, allowing the granular particles to move freely. This fluidisation mechanism is known as internal fluidisation. The concept of internal fluidisation offers an explanation for the erosion of pipe material adjacent to pipe leaks. In this study, the removal of pipe material adjacent to leaks due to internal fluidisation has been termed "leakage-induced pipe erosion." This phenomenon has received minimal attention from researchers in the past. Leakage-induced pipe erosion has the potential to aggravate small existing leaks. There are two main implications of aggravating small leaks; firstly, where water authorities do not utilise active leak detection programmes, aggravating the initial leak conditions of small leaks can result in increased long term water losses. Secondly, in water distribution systems where the water authority does implement active leak detection programmes, aggravating small leaks increases the probability of finding and repairing them. This aim of this study was to experimentally investigate the influence of various factors on the leakage-induced erosion process. Five main factors were investigated, namely bedding material grain size, cover depth, leakage flow rate, initial leak orientation and pipe material. An experimental setup was designed and manufactured in order to provide a controlled environment in which to investigate the factors affecting leakage-induced pipe erosion.

Abstract (sommario):
Il sistema pila-palo è largamente diffuso nelle strutture da ponte grazie ai suoi vantaggi economici e tecnici. Tuttavia questo sistema è fortemente influenzato dagli effetti dell’interazione dinamica terreno-palo-struttura. In aggiunta all’allungamento del periodo fondamentale della struttura, la cedevolezza della fondazione induce una componente rotazionale del moto sismico sul sistema globale che non può essere considerata mediante le comuni procedure di progettazione sismica. Sebbene siano stati sviluppati modelli avanzati per considerare l’interazione terreno-palo-struttura sia in campo lineare e non lineare, i modelli alla Winkler rappresentano uno degli approcci più versatili. In questo lavoro, un modello nonlineare di trave su suolo alla Winkler è stata utilizzato per indagare l’effetto sulla risposta della struttura dei principali aspetti legati al comportamento nonlineare del sistema terreno-fondazione, come ad esempio la plasticizzazione del terreno , la formazione di distacco all’interfaccia palo-terreno, il collasso delle pareti del foro e il degrado o incrudimento ciclico del terreno in prossimità del palo. Sono state eseguite analisi dinamiche incrementali per valutare gli effetti della durata del moto sismico e le non linearità del terreno sulle prestazioni della pila-palo in vari profili di terreno omogeneo e bistrato sia di argilla satura che di sabbia nello stato asciutto o saturo considerando differenti livelli di compattazione. Si è stabilita una procedura per eseguire le analisi dinamiche incrementali considerando gli effetti sia sulla risposta sismica locale sia sulle prestazioni strutturali. Gli effetti dell’interazione cinematica ed inerziale in campo non lineare sono stati analizzati mediante un’ampia indagine parametrica. Le analisi hanno evidenziato il ruolo determinante della componente rotazionale e della durata del moto sismico sulla risposta sismica della pilapalo. I risultati ottenuti sono inoltre stati confrontati con quelli ottenuti mediante un modello lineare. Infine, vengono fatte alcune considerazioni evidenziando le aree grigie della comune pratica di progettazione.
Single column bents on extended pile shafts are widely used in bridges for their economical and technical advantages. Nevertheless, this system is strongly affected by Dynamic Soil- Pile-Structure Interaction. In addition to the lengthening of the fundamental period of the structure, the compliance of the foundation induces a rocking component of the seismic motion experienced by the overall system that cannot be considered by following the procedures of a common seismic design practice. Although advanced models have been developed in order to account for Soil-Pile-Structure Interaction both in the linear and nonlinear range, Winkler-type models represent one of the most feasible approaches. In this work, a Beam on Nonlinear Winkler Foundation model is used to investigate the importance of features typical in soil nonlinear behaviour such as yielding, gapping, soil cave-in and cyclic hardening/degradation effects on the performance of extended pile shafts. A procedure to estimate the model parameters from geotechnical soil characterization is presented. Incremental Dynamic Analyses are performed to evaluate the effects of Ground Motion Duration and soil nonlinearity on the performance of extended pile shafts in various homogeneous and two-layered soil profiles, including saturated clay and sand in either fully dry or saturated state with different levels of compaction. A procedure to perform Incremental Dynamic Analysis, including effects on both site response analysis and on the structural performance, is established. Nonlinear kinematic and inertial interaction effects are analyzed by means of an exhaustive parametric investigation. The significant effects of the rocking component and the Ground Motion Duration on the seismic response of extended pile shafts are demonstrated. Comparisons with results obtained with a linear model are also presented. Finally, some considerations are drawn pointing out grey areas of the common design practice.
