Depåfynd och anledningarna bakom deras nedläggelser har länge varit forskningsfrågor. Begreppet har definierats olika utav diverse författare. Flera forskare har utvecklat kriterier för vad som utgör ett depåfynd, samt om det har nedlagts i sakralt eller profant syfte. Gemensamt för en rituell tolkning är att depåplatsen har extraordinära naturliga egenskaper, något vattenmiljöer uppfattas besitta. Med området Östra Ljungby i Trolle-Ljungby socken, Skåne som undersökningsområde kommer uppsatsen ställa fyndmaterialet mot dessa kriterier. Fyndmaterialet har påträffats i både fast- och våtmark samt består till stor del av olika typer av yxor, verktyg och dolkar som typologiskt dateras till tidsperioder från mesolitikum till äldre bronsålder. Utifrån en hypotes om vattens personskap utforskas även en möjlig koppling mellan vattendepåfynden och folktrossägen. Tidsmässiga likheter och skillnader analyseras samt diskuteras i syfte att förstå deponeringsplatsernas kontinuitet. Det kan slutledas att flera sakrala depåer har nedlagts i Östra Ljungby, där vissa har gjorts på samma plats över långa tidsspann. Alltså finns det tecken som hänvisar till att undersökningsområdet haft en kontinuerlig deponeringstradition. Vidare finns en koppling till seder som gjorts för att skydda sig mot näcken. Däremot bör det belysas att en sådan koppling är svår att fastställa på grund av svårigheterna att rekonstruera forntida ritualer och ideologier. / Hoards and the reason behind their depositions have long been research questions. The term has been defined differently by various authors. Several researchers have developed criteria for what constitutes a hoard, as well as whether it has been deposited for a sacred or profane purpose. Common for a ritual interpretation is that the deposition place has natural properties that are extraordinary, something watery environments are believed to possess. With the area of Östra Ljungby in the parish of Trolle-Ljungby, Skåne as the research area, the essay will compare the finds against these criteria. The material found have been discovered in both solid ground and wetlands, and consists largely of various types of axes, tools and daggers that are typologically dated to time periods from the Mesolithic to the Early Bronze Age. Based on a hypothesis concerning the personhood of water, a possible connection between the wetland hoards and folklore is explored. Temporal similarities and differences are analysed and discussed in order to further understand the continuity of the deposition sites. It can be concluded that several sacral depositions have been made in Östra Ljungby, where some have been made in the same place over long periods of time. Thus, there are signs that point to the study area having a continuous depositional tradition. Furthermore, there is a connection to customs made in order to protect oneself against näcken. However, such a connection is difficult to establish due to the difficulties in reconstructing prehistoric rituals and ideologies.

Den här uppsatsen behandlar 62 mynt från den arkeologiska utgrävningen vid Zeushelgedomen Labraunda på Uppsala universitets myntkabinett. Syftet med uppsatsen är att förstå de kontaktmönster som fanns mellan Zeushelgedomen och omvärlden. Men även att dokumentera och digitalisera mynten. Syftet uppnås genom en nätverksanalys baserad på en kvantitativ myntundersökning och etableringen av en digital myntkatalog över det undersökta materialet. Från nätverksanalysen kan en stark koppling etableras mellan Zeushelgedomen och staden Mylasa. Det var helgedomens funktion som en regional maktbas och starka koppling till Hekatomndierna som utgjorde grunden till relationen. Myntmaterialet bekräftar också Zeushelgedomens omfattande roll under 200 talet f.Kr. då 33 av de undersökta mynten dateras till den tiden. Detta motsäger en vanlig tolkning vilket är att mängden aktiviteter minskade i Zeushelgedomen under den hellenistiska perioden. Med de kompletterande inskrifterna är det tydligt att Labraunda hade en viktig status i den turbulenta tidsåldern som följde Alexander den stores död. Mynten som användes inom helgedomen var för det mesta vanliga bronsmynt såsom nr 501051 från Mylasa och nr 501065 från Stratonikeia. / This essay examines 62 coins from the archaeological excavation at the Zeus sanctuary Labraunda at Uppsala University's coin cabinet. The purpose of the essay is to understand the contact patterns that existed between the Zeus sanctuary and the outside world. But also to document and digitize the coins. The purpose is achieved through a network analysis based ona quantitative coin survey and the establishment of a digital coin catalog of the examined material. From the network analysis, a strong connection can be established between the sanctuary of Zeus and the city of Mylasa. It was the shrine's function as a regional power baseand strong connection to the Hekatomnids that formed the basis of the relationship. The coin material also confirms the extensive role of the sanctuary of Zeus during the 2nd century BC. as 33 of the coins examined date to that time. This contradicts a common interpretation which is that the amount of activity decreased in the sanctuary during the Hellenistic period. With the supplementary inscriptions, it is clear that Labraunda had an important status in the turbulentage that followed the death of Alexander the Great. The coins used within the sanctuary were mostly common bronze coins such as No. 501051 from Mylasa and No. 501065 from Stratonikeia.

Nickel aluminum bronze (NAB) alloys are used in naval and maritime applications for their excellent corrosion resistance under the influence of seawater. One application involves the use of a NAB butterfly valve within a NAB fluid line to control fluid flow of seawater. Due to the chaotic environment, the corrosion rate of the NAB tubing downstream from the valve increases significantly. The disc angle at which the valve alters fluid flow causes an increase in the fluid velocity and an increase in the turbulence produced on the downstream side of the valve. These fluid conditions contribute to the increase in the corrosion rate of the NAB piping downstream from the valve. This thesis aims to characterize how the change in the disc angle of the butterfly valve causes a change in the erosion-corrosion rate of NAB downstream from the valve. A butterfly valve is simulated using orifice plates of varying diameters to mimic flow conditions at different disc angles. An orifice plate is a simple device with a hole in its center that is designed to restrict fluid flow across a fluid line. Under the same hydrodynamic conditions, the orifice produces nearly the exact same flow coefficients as the valve. At a volumetric flowrate of 0.00757 m^3/s a total of eight locations found along the liquid/metal interface produced pitting sites. The average passivation layer thickness is also measured. / Master of Science / Nickel aluminum bronze alloys are used within the naval and maritime industries for many different types of applications. The main use of this material as studied within this project entailed the use of this alloy within a piping structure downstream from a type of butterfly valve. When seawater flows through this piping structure, the valve distortions within the fluid are believed to cause degradation of the piping material. This project aimed to look at how the change in the disc angle of the butterfly valve caused disruptions in the fluid and thereby changes in how nickel aluminum bronze degrades over time. It was found that as the disc angle inside of the butterfly valve decreased towards being completely closed, the greater the amount of degradation was produced upon the alloys surface. Micrographs within this paper aimed to characterize the amount of degradation upon the alloy surface and also report the overall thickness of oxide deposited onto the metal surface during testing.

[ES] La presente tesis doctoral se sitúa en el marco de la actual transición energética, que plantea la sustitución progresiva de materias primas de origen fósil por fuentes renovables, tanto para la obtención de productos químicos como para la producción de combustibles. En este contexto de transición paulatina a las renovables, y teniendo en cuenta los últimos pronósticos, las fuentes fósiles (fundamentalmente gas natural) y derivados de la biomasa, jugarán un papel fundamental durante el cambio. Se ha llevado a cabo un estudio sobre el empleo de óxidos metálicos (basados en bronces de wolframio o en óxido de níquel), como catalizadores para: i) la transformación de derivados de biomasa: de glicerol a acroleína/ácido acrílico; y de compuestos oxigenados de cadena corta presentes en efluentes acuosos (procedentes de tratamientos de extracción de bio-aceites de pirolisis) a combustibles; y ii) la transformación de componentes del gas natural, concretamente la obtención de etileno a partir de etano, mediante deshidrogenación oxidativa (ODH). El trabajo se presenta desde una perspectiva de la química de materiales, haciendo hincapié en las propiedades fisicoquímicas de los distintos sistemas catalíticos, empleando técnicas de caracterización convencionales e in situ, además de reacciones modelo (transformación de metanol y etanol), con el objetivo de entender las funciones catalíticas presentes en cada caso. Tanto para la transformación de glicerol en fase gas, como para la valorización de mezclas acuosas de compuestos oxigenados de cadena corta, se han utilizado catalizadores basados en bronces de wolframio. Se ha tratado de poner de manifiesto la gran versatilidad composicional y estructural (con el consiguiente control de las propiedades funcionales), que presentan este tipo de materiales. En este sentido, las propiedades ácidas y redox de catalizadores W-V-O pueden ser moduladas, para una misma concentración de vanadio, mediante el control de la relación de fases cristalinas (hexagonal y monoclínica) del óxido de wolframio. Este efecto se ha estudiado empleando la transformación aeróbica de metanol como reacción "test", y tiene una gran influencia en la deshidratación oxidativa de glicerol a ácido acrílico. A su vez, mediante la sustitución isomórfica de wolframio por niobio (en el sistema WO3-Nb2O5) es posible controlar la relación de centros ácidos de tipo Brönsted y Lewis en la superficie de los materiales. Por un lado, los catalizadores con una alta relación Brönsted/Lewis se han mostrado más efectivos en la deshidratación de glicerol a acroleína, mientras que los catalizadores con altas concentraciones de centros de tipo Lewis presentan altos rendimientos a productos de condensación de compuestos oxigenados de cadena corta. Adicionalmente se han estudiado las diferencias entre catalizadores (bien óxidos mixtos W-V-O o W-Nb-O) preparados mediante un método hidrotermal o mediante reflujo, así como el efecto de la utilización de un soporte mesoporoso (KIT-6), sobre sus propiedades catalíticas en la transformación aeróbica en fase gaseosa de etanol y glicerol. Finalmente, en lo que concierne a la transformación de componentes del gas natural, se han empleado materiales basados en óxido de níquel (soportado sobre distintos óxidos y/o promovido con distintos metales) como catalizadores para la ODH de etano. En este caso el estudio se ha centrado fundamentalmente en dilucidar los efectos de promotores y soportes en la naturaleza y propiedades fisicoquímicas del óxido de níquel, los cuales dan lugar a un cambio drástico en sus propiedades catalíticas. Así, se ha observado que modificando la reducibilidad y las características superficiales del óxido de níquel es posible transformar un catalizador muy poco selectivo en la ODH de etano (como es el NiO, con una selectividad a etileno del 30 %) en uno de los catalizadores más selectivos para llevar a cab / [CA] Aquesta tesi doctoral es situa dins del marc de l'actual transició energètica, la qual planteja la substitució progressiva de les primeres matèries d'origen fòssil per fonts renovables, tant per a l'obtenció de productes químics com per a la producció de combustibles. En aquest context de transició gradual a les renovables, i tenint en compte els últims pronòstics, les fonts fòssils (principalment el gas natural) i els derivats de la biomassa, exerciran un paper fonamental durant aquest canvi. S'ha dut a terme un estudi sobre la utilització d'òxids metàl·lics (basats en bronzes de wolframi o en òxid de níquel), com a catalitzadors per a: i) la transformació de derivats de la biomassa: de glicerol a acroleïna/àcid acrílic; i de compostos oxigenats de cadena curta presents en efluents aquosos (procedents de tractaments d'extracció de bio-olis de la piròlisi) a combustibles; i ii) la transformació de components del gas natural, concretament l'obtenció d'etilè a partir d'età, mitjançant la deshidrogenació oxidativa. El treball es presenta des del punt de vista de la química de materials, posant l'accent en les propietats fisicoquímiques dels diferents sistemes catalítics, utilitzant tècniques de caracterització convencionals i in situ, a més de reaccions model, amb l'objectiu d'entendre les funcions catalítiques presents en cadascun dels casos. Tant per a la transformació del glicerol en fase gasosa com per a la valorització de les mescles aquoses de compostos oxigenats de cadena curta, s'han utilitzat catalitzadors basats en bronze de wolframi. S'ha intentat posar de manifest la gran versatilitat de composicions i estructures (amb el conseqüent control de les propietats funcionals) que presenten aquest tipus de materials. En aquest sentit, les propietats àcides i redox dels catalitzadors de W - V - O poden ser modulades, per a una mateixa concentració de vanadi, mitjançant el control de la relació de fases cristal·lines (hexagonal i monoclínica) de l'òxid de wolframi. Aquest efecte s'ha estudiat utilitzant la transformació aeròbica de metanol com a reacció "test", i presenta una gran influència en la deshidratació oxidativa de glicerol a àcid acrílic. Al mateix temps, mitjançant la substitució isomòrfica de wolframi per niobi (en el sistema WO3 - Nb2O5), és possible controlar la relació de centres àcids de tipus Brönsted i Lewis en la superfície dels materials. Per una part, els catalitzadors que presenten una relació Brönsted / Lewis alta s'han mostrat més efectius en la deshidratació de glicerol a acroleïna, mentre que els catalitzadors amb unes altes concentracions de tipus Lewis presenten alts rendiments a productes de condensació de compostos oxigenats de cadena curta. Addicionalment, s'han estudiat les diferències entre catalitzadors (ja siguin òxids mixtos W-V-O o W-Nb-O) preparats mitjançant un mètode hidrotermal o mitjançant un mètode de reflux, així com l'efecte que presenta la utilització d'un suport mesoporós (KIT-6), sobre les seves propietats catalítiques en la reacció de transformació aeròbica en fase gasosa d'etanol i glicerol. Finalment, pel que fa referència a la transformació de components del gas natural, s'han utilitzat materials basats en òxid de níquel (suportat sobre diferents òxids i/o promoguts amb diferents metalls) i catalitzadors per a la deshidrogenació oxidativa d'età. En aquest cas, l'estudi s'ha focalitzat principalment en dilucidar els efectes de promotors i suports en la naturalesa i propietats fisicoquímiques de l'òxid de níquel, els quals impliquen un canvi dràstic en les seves propietats catalítiques. Així doncs, s'ha observat que modificant la reductibilitat i les característiques superficials de l'òxid de níquel és possible transformar un catalitzador molt poc selectiu en la deshidrogenació oxidativa de l'età (com és el cas del NiO, amb una selectivitat a l'etilè del 30%) en un dels cata / [EN] The present doctoral thesis is set within the scope of the current energy transition, which considers the progressive substitution of non-renewable fossil sources by renewable feedstocks for the production of chemicals and fuels. In this context of gradual transition, and according to recent energy outlooks, fossil sources (especially natural gas) and biomass feedstocks will play a key role during the shift. A study on the use of metal oxides (based on tungsten bronzes or nickel oxides) as catalysts for different reactions has been conducted. Particularly, they have been studied as catalytic materials for: i) the transformation of biomass-derived feedstocks: glycerol transformation into acrolein/acrylic acid, and the transformation of short-chain oxygenates present in aqueous effluents (derived from extraction processes of pyrolysis bio-oils) into fuels; and ii) the valorization of natural gas components, i.e. the transformation of ethane into ethylene by oxidative dehydrogenation. The work is presented from a materials chemistry perspective, emphasizing the physicochemical characteristics of the different catalytic systems by using conventional and in situ characterization techniques and model reactions (gas phase methanol and ethanol transformation); with the aim of understanding the specific catalytic functionalities present in each case. For both gas phase glycerol transformation and the valorization of short-chain oxygenates aqueous mixtures, catalyst based on tungsten oxide bronzes have been used. The compositional and structural versatility of this structural types (with the subsequent control of their functional properties) will be highlighted. In this sense, the acid-redox properties of W-V-O catalysts can be modulated by controlling the crystalline phase composition in the materials (i.e. hexagonal and monoclinic polymorphs of tungsten oxide) at a fixed V concentration. This effect has been studied by using the gas-phase aerobic transformation of methanol as a surface test reaction. The concentration of the hexagonal and monoclinic polymorphs in the catalysts has also an important influence in the gas-phase transformation of glycerol into acrylic acid. Also, it is possible to control the Brönsted/Lewis acid nature of the surface by the isomorphic substitution of Nb for W in WO3-Nb2O5 system. On the one hand, catalysts showing a higher proportion of Brönsted acid sites are more effective in the glycerol dehydration to acrolein. On the other hand, materials with a higher concentration of Lewis acid sites display high yields to condensation products in the aqueous phase valorization of short chain oxygenates. Additionally, the differences between W-V-O and W-Nb-O catalysts prepared by both reflux and hydrothermal methods have been studied. Also the effect of adding a mesoporous KIT-6 silica as support on the catalytic performance in the gas phase transformation of ethanol and glycerol will be underlined. Considering the transformation of natural gas components, nickel oxide-based materials were chosen (either supported on different oxides and/or promoted with different metals) to perform the oxidative dehydrogenation (ODH) of ethane. In this case the study has been focused on elucidating the effects of both promoters and supports on the nature and physicochemical features of nickel oxide, which lead to a drastic change in the catalytic behavior of these materials. This way, it has been observed that by the modification of the reducibility and the chemical nature of nickel oxide, it is possible to transform an apparently non-selective catalyst in the ODH of ethane (like NiO, showing a selectivity to ethylene of ca. 30 %) into one of the most selective catalysts reported in the literature (presenting a selectivity to ethylene of ca. 90 %). / También me gustaría agradecerle al Prof. Avelino Corma, investigador principal del proyecto SEV-2012-0267, a través del cual he podido realizar mi tesis doctoral enel Instituto de Tecnología Química (SVP-2014-068669). / Delgado Muñoz, D.

There is great interest in the development of new polar dielectric ceramics and multiferroic materials with new and improved properties. A family of tetragonal tungsten bronze (TTB) relaxors of composition Ba₆M³⁺Nb₉O₃₀ (M³⁺ = Ga³⁺, Sc³⁺ and In³⁺, and also their solid solutions) were studied in an attempt to understand their dielectric properties to enable design of novel polar TTB materials. A combination of electrical measurements (dielectric and impedance spectroscopy) and powder diffraction (X-ray and neutron) studies as a function of temperature was employed for characterising the dynamic dipole response in these materials. The effect of B-site doping on fundamental dipolar relaxation parameters were investigated by independently fitting the dielectric permittivity to the Vogel-Fulcher (VF) model, and the dielectric loss to Universal Dielectric Response (UDR) and Arrhenius models. These studies showed an increase in the characteristic dipole freezing temperature (T[subscript(f)]) with increase B-cation radius. Crystallographic data indicated a corresponding maximum in tetragonal strain at T[subscript(f)], consistent with the slowing and eventual freezing of dipoles. In addition, the B1 crystallographic site was shown to be most active in terms of the dipolar response. A more in-depth analysis of the relaxor behaviour of these materials revealed that, with the stepwise increase in the ionic radius of the M³⁺ cation on the B-site within the Sc-In solid solution series, the Vogel-Fulcher curves (lnf vs. T[subscript(m)]) are displaced to higher temperatures, while the degree of relaxor behaviour (frequency dependence) increases. Unfortunately, additional features appear in the dielectric spectroscopy data, dramatically affecting the Vogel-Fulcher fitting parameters. A parametric study of the reproducibility of acquisition and analysis of dielectric data was therefore carried out. The applicability of the Vogel-Fulcher expression to fit dielectric permittivity data was investigated, from the simple unrestricted (“free”) fit to a wider range of imposed values for the VF relaxation parameters that fit with high accuracy the experimental data. The reproducibility of the dielectric data and the relaxation parameters obtained by VF fitting were shown to be highly sensitive to the thermal history of samples and also the conditions during dielectric data acquisition (i.e., heating/cooling rate). In contrast, UDR analysis of the dielectric loss data provided far more reproducible results, and to an extent was able to partially deconvolute the additional relaxation processes present in these materials. The exact nature of these additional relaxations is not yet fully understood. It was concluded application of the Vogel-Fulcher model should be undertaken with great care. The UDR model may represent a feasible alternative to the evaluation of fundamental relaxation parameters, and a step forward towards the understanding of the dielectric processes in tetragonal tungsten bronzes.

La masse de documentation céramique disponible pour les différentes phases de la Protohistoire corse était aussi quantitativement importante que peu étudiée. L’analyse de ces sources (43 collections issues de 35 sites) selon une méthodologie basée sur les rapports de proportion, couplée au réexamen critique des publications et des datations radiocarbone, engendre une vision renouvelée de la structure chrono-culturelle des groupes insulaires entre Bronze final et premier âge du Fer. Pour aboutir, par sériation et périodisation, à un schéma reposant sur une articulation entre des entités matérielles clairement définies, il a notamment fallu se détacher de certains faux problèmes à l’origine d’hypothèses initiales souvent arbitraires ou trop tranchées. Les principaux résultats font apparaître une structuration polygénique complexe des assemblages céramiques, subtil jeu d’équilibre entre tradition, emprunt et innovation en fonction des époques et des contextes, mais qui intègre pleinement la Corse dans les dynamiques tyrrhéniennes et méditerranéennes à l’aube de l’avènement des premières sociétés historiques. / The amount of information available on ceramic ware from the different phases of Corsican protohistory is as quantitatively important as little studied. An analysis of these sources (43 collections from 35 sites) using a methodology based on ratios of proportion, as well as a critical re-examination of publications and radiocarbon dates, brings about a new understanding of the chrono-cultural structure of island groups between the Late Bronze and the Early Iron Ages. After resolving a few of the issues which led to previous arbitrary and incomplete analyses, it has been possible to generate a schema based on clearly defined material elements using seriation and periodisation. The main results show a complex polygenic structure in the ceramic assemblages, a subtle game of balance between tradition, borrowing and innovation in relationship to periods and contexts that plainly integrates Corsica in Tyrrhenian and Mediterranean dynamics at the dawn of the first historic societies.

This thesis studies the contacts between Scandinavia and the Mediterranean area during the Scandinavian Bronze Age. These contacts have been the topic of controversy for a long time as one side of the debate believes in direct contacts between Scandinavia and the Mediterranean area, and the other side believes that contacts between the two areas could only have been by down the line trading contacts. This thesis then aims to see what evidence there is that the contacts would have been direct or otherwise. This is done by studying the archaeological evidence as well as the pictographic depictions on rock art in Scandinavia and painted pottery from the Mediterranean area, as well as ships and ship technology to understand if Scandinavian ships would have been able to travel to the Mediterranean in the first place. Further, this thesis also studies the urn burials introduced to Scandinavia during the Bronze Age from northern Italy to see the spreading of ideas, as well as isotope analysis of bronze from Sweden and Denmark together with strontium analysis of Bronze Age individuals to form a complete picture about these contacts and how they took place.

Ce travail vise à étudier les techniques de fixation des statues sur leurs bases dans le monde grec, depuis la fin du VIIe s. jusqu’à la fin de l’époque hellénistique, à partir des bases inscrites. Il se fonde sur l’étude d’un corpus de 387 monuments ayant conservé des traces de fixation, à Delphes, Délos et Athènes, décrits et analysés dans un catalogue dédié. La première partie est consacrée à l’établissement d’une chrono-typologie des techniques de fixation visant à les caractériser en fonction du matériau, de la taille et du type de figure, et à les dater. La seconde partie s’attache à l’interprétation des traces de fixation en comme empreintes de la statue disparue. On a d’abord déterminé le type d’informations qu’elles pouvaient apporter sur elle, comme son matériau et sa taille, mais aussi son type et surtout sa position. On s’est ensuite intéressé aux bases signées, afin de dégager des traditions artisanales propres à des régions ou des ateliers, en croisant la fixation utilisée et les positions révélées par les traces. Enfin, on s’est interrogé sur les évolutions de l’utilisation des matériaux ; on a pu dégager le rôle des contextes d’exposition à partir de l’époque classique, et contribuer à élucider le retour du marbre à partir du IIe s. Cette étude entend par là contribuer aux recherches sur les techniques de fabrication autant qu’à celles sur la sculpture dans son contexte. / The study examines the techniques used to attach statues to their bases in the Greek world from the end of the 7th c. BC to the end of the Hellenistic period. Starting from bases bearing inscriptions, it builds on a corpus of 387 monuments from Delphi, Delos and Athens, showing traces of attachment. Their description and analysis can be found in a separated catalogue. In the first part of the study, a chrono‐typology was elaborated, identifying and dating each technique according to the material, the size and the type of the figures. In the second part, the traces of attachment were interpreted as signs of the missing statue. First, we showed that these traces brought information on its material and its size but also its type and its position. Then we focused on signed bases and proceeded to a cross‐examination of the kind of technique used and the position revealed by the traces in order to identify artisanal traditions specific to regions or workshops. Finally, we considered the reasons for using marble or bronze for statues; we thus showed the importance of the setting context from the classical period onward, as exemplified by the come-back of marble sculpture in the 2nd c. BC. The study is thus intended as a contribution to research both on attachment techniques and sculpture in its context.

Notre étude porte sur les pierres à aiguiser, pierres à affûter, polissoirs et autres outils de l’abrasion découverts dans des sites égéens de l’Âge du Bronze. Durant cette période, les ressources lithiques naturelles égéennes prélevées étaient transformées et employées lors des actions d’abrasion, d’aiguisage, d’affûtage, de polissage. Une connaissance empirique du comportement des roches durant l’utilisation a guidé la sélection des supports afin d’optimiser l’efficacité de l’outillage lors des différentes opérations. Une analyse des provenances nous éclaire sur les modes d’acquisition et de circulation des matériaux ; et une étude complémentaire des propriétés mécaniques des roches nous renseigne sur les paramètres qui ont guidé le choix des matériaux. Les outils diffèrent de par leur matière première mais aussi de par leur morphologie, granulométrie et leurs traces d’usage. Cette recherche propose la mise en place d’une nouvelle analyse des traces, permettant de distinguer les stigmates d’usage et les usures. La méthodologie s’appuie sur des analyses menées en laboratoire (analyses pétrographiques, tribologiques), combinées à des observations sur des outils à différentes échelles. Une fois la fonction des outils identifiée, nous avons considéré les contextes de production et d’utilisation. Enfin, des études ethnographiques et la consultation d’outils archéologiques menées tout au long de nos recherches, nous ont permis de reconstituer les activités, les actions et les gestes liés à la fabrication et à l’utilisation des outils. / This research aims at investigating the supplying strategies of raw materials selected for the implementation of lithic tools in the Aegean sea during the Bronze Age. Furthermore, it addresses the possible exchange networks responsible for the wider distribution of abrasive rocks. Particularly, all steps of the operational process (chaîne opératoire) were investigated from the extraction of raw materials to the use of the stone tools. These research objectives were addressed through an interdiscipinary approach, which combines the petrographic, morphological, and use-wear analysis of lithic tool implements based on both macroscopic and microscopic observations. The purpose of the use wear analysis was the identification of the different functions among these tools within their historical and archaeological context. Additionally, this study developed a precise terminology of manual movements and gestures associated with the use of these tools by combining ethnographical and experimental data with archaeological evidence.

However, the Temple as presented in the Hebrew Bible never existed, because no more than an annex king s palace; it s also not factual the myths circulating the kings David and Solomon, which were not as grand as the Hebrew Bible points. Nevertheless, on two occasions in the history of Judah, the Deuteronomist Revolution and the Return of the Captivity, the Temple had a centralizating function and required many founding myths to legitimize it. With such myths, the people who were near the Temple felt more part of the House of Yahweh for believing participate of a plan established by the Creator of the Universe and all the stories invented and developed by the Deuteronomist and the Priestly gave them greatest joy and hope. What happened in fact was the king s power legitimacy in the context of Deuteronomist Reform and the priest s power in the return of the Captivity in the early Persian period. As for the post-exile, for being a more recent period, is greater amount of elements that characterize the stimulation of popular imaginary regarding the First Temple than in the period of the Deuteronomist Reform, despite the latter being period of prosperity for the Kingdom of Judah / A presente tese de doutorado visa apresentar o que veio a ser construído através do imaginário sobre o Primeiro Templo de Salomão, o qual muitas pessoas ainda acreditam nos dias de hoje que seja factual. Entretanto, o Templo, conforme o apresentado na Bíblia Hebraica, jamais existiu, pois não passava de um anexo do palácio do rei; tão pouco são factuais os mitos que circulam em torno dos reis Davi e Salomão, que não foram tão grandiosos quanto a Bíblia Hebraica aponta. Apesar disso, em dois momentos da História de Judá, na Revolução Deuteronomista e no Retorno do Cativeiro, o Templo teve uma função centralizadora e necessitava de diversos mitos fundantes para ser legitimado. Com tais mitos, o povo que estava próximo ao Templo sentia-se mais parte da Casa de Yahweh por acreditar fazer parte de um plano estabelecido pelo Criador do Universo e todas as histórias inventadas e elaboradas pelo Deuteronomista e pelo Sacerdotal lhes davam maior alegria e esperança. O que houve, de fato, foi a legitimação do poder do rei, no contexto da Reforma Deuteronomista, e do poder do Sacerdote, no retorno do Cativeiro, no começo do Período Persa. No pós-exílio, por ser um período mais recente, encontra-se maior quantidade de elementos que caracterizam o estímulo do imaginário popular sobre o Primeiro Templo do que no período da Reforma Deuteronomista, apesar deste último ser um período de prosperidade para o Reino de Judá
