This dissertation examines the iconographical motif of the Apollonian triad in Attic art of the sixth and fifth centuries BC. Attic vase paintings constitute the chief evidence for this study, but other evidence, such as inscriptions, literary sources, sculptures and coins is considered, as well. My thesis focus on scenes without a clear mythological context, where the triad appears alone or accompanied by other, mostly, divine figures, and on what messages or information these images of the Apollonian triad convey. This study contributes to the ongoing discussion of the iconography and iconology of Attic vases, which enriches our understanding of Athenian socio-political and religious life and of Greek culture, more generally.

The antics of Helen of Sparta, famous both for her beauty and her adultery, have fascinated ancient and modern audiences alike. The subjects of her abduction from Sparta and recovery from Troy are explored in various ancient discourses. This study investigates the iconography of Attic vase-paintings, c. 550-350 BCE, that show (or have been identified as depicting) these two events in the life of Helen. My approach seeks to investigate their subtexts or metanarratives of emotion through a rigorous methodology. This process first involves engaging in a close reading of the vase scenes in order to identify their visual language, especially their emotional vocabulary. The second process contextualises the vases in the society that produced and used them. By reading them in their original context of production and reception, one can extrapolate a range of meanings these scenes could have had for their original audience. In doing this, there are two main goals: to establish which emotions are pertinent to the ancient audience in these two episodes (emotional content), and how emotions – in essence invisible – are communicated in the vase images (emotional language). Applying this methodology to the scenes yields significant results. The identification of the most typically emotional indicators includes the following: gesture; stance; gaze; clothing, physical attributes and icons; divinities and personifications; and contextual icons or information. The emotional content that emerges includes, in particular, the emotion of eros – its potentially destabalising and emasculating consequences – and the appropriateness of orgē and revenge. Another significant result is in relation to the traditional identification of the scenes. While most of the traditional identifications of Helen’s recovery stand firm, the opposite is true for the abduction. My rejection of the majority of images identified as Helen’s abduction by traditional scholarship is necessary due to a lack of evidence – inscriptional or iconographic – and the marked incongruity of these depictions with their context. These results demonstrate the merits of a solid methodology that takes the language of images seriously, as well as the social, political and ideological context in which the vases were produced and viewed.

The primary objective of this research was to identify practices by which specialty cut flower growers can extend the vase life of cut delphinium, sunflower, and dahlia. Experiments investigated the effects of nitrogen fertilization rate on delphinium 'Guardian Mix' and the effects of deficit irrigation on delphinium 'Guardian Blue.' 'Guardian Mix' plants produced marketable cut stems at nitrogen rates as low as 50 mg/L. Deficit irrigation did not change vase life, stomatal conductance, or transpiration rates of delphinium 'Guardian Blue.' Studies tested the effects of foliar calcium applications or benzyladenine application on sunflower 'Moulin Rouge' and 'Procut Lemon.' Calcium did not change the vase life, stomatal conductance, or transpiration rates of either sunflower cultivar. Benzyladenine applied as a preharvest spray or a postharvest dip did not alter vase life of sunflower 'Moulin Rouge' or 'Procut Lemon.' Transpiration rate and conductance rates of sunflowers significantly decreased in the first three days after harvest. In both sunflower experiments, vase life of 'Moulin Rouge' was shorter than vase life of 'Procut Lemon.' Benzyladenine was also applied to dahlia 'Park Princess' and 'Karma Yin Yang' cut flowers. Benzyladenine did not change dahlia vase life. Dahlia 'Park Princess,' 'Bride to Be,' 'Cherish,' and 'Lollipop' cut flowers were not sensitive to exogenous ethylene. Further experiments tested the effect of flower stage at harvest, vase water temperature, or preharvest fungicide application on dahlia 'Park Princess' and 'Karma Yin Yang' cut flowers. Vase life of 'Park Princess' flowers was extended when flowers were harvested before fully open, but 'Park Princess' flowers harvested at budbreak failed to open completely after harvest. 'Karma Yin Yang' cut flower vase life did not differ when flowers were harvested at different stages. Placing cut dahlias in hot vase water had varied effects, but did not extend vase life of either cultivar. Fungicide applications extended vase life of 'Park Princess' flowers. However, the use of fungicide is not necessary to prevent postharvest fungal infection in cut dahlias. The results of all experiments indicate that optimal handling practices vary between cut flower taxa and that factors determining cut flower vase life are complex. / Master of Science

Thesis (MPhil)--Stellenbosch University, 2013. / ENGLISH ABSTRACT: During the fifth century BCE there were three defining periods in Athenian history that challenged its society: the Persian Wars (490 – 479 BCE); Periclean Athens (mid-fifth century); and the Peloponnesian War (431 – 404 BCE). As the development of identity is a reactionary process, these three periods had a profound effect on the Athenian identity and led to the redefinition of this self-image along the primordialist models. Two premises are combined in this study. Firstly that comparisons to contrary ethnicities are vital to the development of identity, and secondly that the visual articulation of an identity is essential to the reinforcement and maintenance of this self-image. This can be applied to the development of Athenian identity during the fifth century BCE as reflected in Attic vase painting. Through a study of the "other" imagery produced in this century, with special attention given to Amazons, it is possible to see the development and nature of the Athenian identity during each of the three periods. / AFRIKAANSE OPSOMMING: Tydens die vyfde eeu vC was daar drie omskrywende periodes in Atheense geskiedenis wat hul samelewing uitgedaag het: die Persiese Oorloë (490 – 479 vC); Perikleiese Athene (mid-vyfde eeu); en die Pelopponiese Oorlog (431 – 404 vC). Omdat die ontwikkeling van identiteit 'n reaksionêre proses is, het hierdie drie periodes 'n diepgaande indruk op die Atheense identiteit gehad en het bygedra tot die herdefiniesie van hierdie selfbeeld volgens die primordialis modelle. Twee stellings word gekombineer in hierdie studie. Eerstens dat vergelykings aan teenoorgestelde etnisiteite essensieel is vir die ontwikkeling van identiteit, en tweedens, dat die visuele artikulasie van 'n identiteit noodsaaklik is vir die versterking en onderhoud van die selfbeeld. Dit kan toegepas word by die ontwikkeling van Atheense identiteit gedurend die vyfde eeu vC soos in Attiese vaas versiering uitgebeeld is. Deur middel van 'n studie van die "ander" beelde geskep in die eeu, met spesiale aandag aan Amasone, is dit moontlik om die ontwikkeling en karakter van die Atheense identiteit gedurend elk van die drie periodes te verstaan.

As one of many other distinct painting styles that appeared on ceramics throughout the Guatemalan Lowlands of the Late Classic Period (AD 600-900), the Red Background vases represented the economic reach of the owner into local and foreign courtly culture. Supernatural processions, playful hieroglyphic texts, and the distinctive red background circulated on vases, plates, and bowls in order to perform prestige and the elite identity in public feasts. The diverse narrative content of these vessels reveals the importance of mytho-historic origin stories and supernatural identities to the prevailing political order, while the unique hieroglyphic texts link the style and its imagery to the royal court of Pa’ Chan. However, the lack of context for most of these vases thwarts a straightforward understanding of their role in Maya society as objects from a specific geographic place with archaeological provenience. Despite this inability to embed the Red Background vases within a robust archaeological framework, the production and circulation of a visually distinct style by a named community still indicates that the creators of these objects wished to communicate a unique artistic identity through an intersection of formal qualities. Refocusing the question of agency through the lens of the final product reveals that these works acted as part of a larger campaign to create the typical courtly trappings of master artisan production and public social feasting with representatives of other powerful polities. This Master’s Thesis aims to examine the current corpus of almost sixty vases in order to describe how the Red Background style manifests. In addition, my study explores the tendency of many polychrome styles to link a specific royal court with the artistic product through hieroglyphic emblems. I conclude that the unique Pa’ Chan emblem takes this extroverted statement of belonging to a higher level, providing an emic classification of the vase where the text comprises a social category of art that performs identity through its distinct visuals. / text

La résolution des images a dû être modifiée afin de respecter les droits d'auteurs. Voir le tableau comprenant la liste des vases afin de trouver ces images en meilleure qualité. / La présente étude sert à rassembler tous les vases attiques à figure rouge présentant des scènes sexuellement explicites connues à ce jour. Un examen attentif de ces sources permit de les décrire ainsi que de les comparer afin d'en faire ressortir les similitudes et les différences. Ces vases, étrangement, proviennent majoritairement d'Étrurie, ce qui surprend lorsqu'on sait qu'ils ont été fabriqués en Grèce. Grâce à l'étude du commerce à cette époque, on constate que ces vases n'occupaient pas une grande place dans les relations commerciales entre Grecs et Étrusques. De plus, ces derniers les utilisaient dans un contexte funéraire, ce qui diffère grandement des Grecs. En effet, ces derniers semblent avoir utilisé ces vases dans un contexte où le vin était central, le symposion. Bien que ce genre de banquet était une activité généralement domestique, on se rend compte, à la lumière de découvertes archéologiques, que les vases sexuellement explicites auraient pu être utilisés dans un contexte lié à la prostitution, les bordels. Ceci nous amène donc à nous questionner quant au statut des femmes qui y sont représentées. Finalement, l'étude des sources littéraires, de peu contemporaines aux vases à l'étude, nous renseigne, en partie, sur les opinions quant aux différentes pratiques sexuelles de l'époque. Au final, bien que des pistes théoriques intéressantes se dégagent de l'étude de ces vases, il reste que des conclusions sûres et hors de tout doute sont impossibles étant donné le manque de source. Ces vases présentent donc un portrait à mi-chemin entre la réalité et le symbolisme de la sexualité en Grèce antique. / This study serves to collect all the red-figure Attic vases with sexually explicit scenes known to date. A close examination of these sources made it possible to describe and compare them to bring out the similarities and differences. These vases, strangely, come mainly from Etruria, which is surprising when we know that they were made in Greece. Through the study of trade at that time, we see that these vases did not occupy an important place in the trade relations between Greeks and Etruscans. In addition, they used them in a funerary context, which differs greatly from the Greeks. Indeed, they appear to have used the vases in a context where the wine was central, the symposion. Although this kind of banquet was generally a domestic activity, we realize, in light of archaeological discoveries, that sexually explicit vases could have been used in a context related to prostitution, brothels. This leads us to question the status of the women that are represented. Finally, literary sources that are contemporary of the studied vases, tells us, in part, on different views on the sexual practices of the time. Finally, although interesting theoretical tracks emerge from the study of these vases, it remains that firm conclusions are impossible given the lack of source. These vases therefore gives us a portrait halfway between reality and symbolism of sexuality in ancient Greece.

Cette thèse a pour but d'améliorer la compréhension des interconnexions entre les processus hydro-sédimentaires et l'évolution morphologique du littoral guyanais, formés à partir des énormes apports sédimentaires amazoniens. Elle s'appuie sur trois échelles spatiales : la côte des Guyanes, le banc de vase et la vasière. L'amortissement des houles à la côte ainsi que les processus de migration des bancs ont été étudiée à l'échelle de la côte des Guyanes. Ce travail apporte une vision structurelle des zones subtidales des bancs et met aussi en évidence les différents processus et forçages (houle, courant) responsables du transport sédimentaire, en fonction de la bathymétrie (> 5 m et < 5 m). L'évolution morphologique du banc de Kourou et des surfaces de mangrove côtières associées, ont aussi été étudiées. Un lien a ainsi été exposé entre, l'implantation des palétuviers, les régimes de courant et la topographie de la vasière. Cette relation a permis d'aborder l'aspect prédictif de l'expansion des surfaces de mangrove côtière. À l'échelle de la vasière, les zones intertidales sont divisibles en deux secteurs géographiques avec des dynamiques sédimentaires bien distinctes : le front de mer et les zones internes. La morphologie des vasières est abordée, tout comme les processus sédimentaires ayant lieu au niveau de la zone interne. Une méthode de reconstitution des apports sédimentaires de la zone interne est aussi proposée. Cette étude souligne l'importance des interactions entre les sédiments cohésifs et la houle, qui modèlent la morphologie du littoral. Les influences des forçages hydrométéorologiques sur la morphodynamique des bancs de vase et l'évolution du trit de côte sont soumises à discussion. / The aim of this work is to improve the knowledge of the interconnections between hydro-sedimentary processes and Guianese's coastal morphology evolution, formed by the sedimentary Amazon discharge. This subject follows three spatial scales : the Guianese's Coast, the mud bank and the mudflat. Coastal waves damping by mud and migration process have been studied at the Guianese's Coastal scale. This study also gives a structural vision of subtidal part of banks and highlights the various processes and hydrodynamics conditions needed for sedimentary transport, for two bathymetric areas (> 5 m and < 5 m depth). The morphological evolution of Kourou's mud bank and the associated surfaces of coastal mangrove are also analysed. A link between mangrove colonisation, currents and the mudflat topography is highlighted. This relation allows a discussion about predictive aspect of the mud banks colonisation by mangrove. At the mudflat scale, intertidal part is divided in two areas with different sedimentary dynamic processes : sea front and internals zones. The morphologycal structure and the sedimentary processes of internals zones are analysed. An historical reconstitution method of sedimentary supplies is also proposed. This study underlines morphological coastal changes sensitivity to hydro meteorological forcing and interactions between cohesive sediment and swells which seems to lead the morphological coastal evolution.

O Grupo Corumbá, SW Brasil, documenta uma etapa importante na evolução da vida por causa de seu registro fóssil de microbialitos, microfósseis, e organismos multicelulares indicativos da complexidade cada vez maior da biosfera no final do período Ediacarano. A importância paleobiológica da Formação Bocaina, inserido no meio do Grupo Corumbá, e datado em cerca de 560 Ma, é embasada em sua diversidade de microbialitos e registro de significativo evento fosfogenético, associados a supostos \"microfósseis em forma de vaso\", semelhantes à tecamebas, interpretadas como os primeiros protistas heterótrofos. Estes fósseis, bem como formas semelhantes reconhecidos em outras unidades geológicas do mundo, precedem o registro da explosão de organismos multicelulares macroscópicos esqueléticos (Cloudina, Corumbella) na formação sobrejacente Tamengo (543 Ma). A morfologia do microbialitos fornece evidências de variação local do nível do mar durante a deposição da Form ação Bocaina. As análises morfológicas e químicas dos microfósseis usando microscopia óptica e eletrônica de varredura, EDS e espectroscopia Raman ajudaram a esclarecer a natureza biológica desses objetos e, assim, contribuir para a compreensão da importância da evolução da vida no Ediacarano, na Formação Bocaina, Grupo Corumbá. / The Corumbá Group, SW Brazil, documents an important stage in the evolution of life because of its fossil record of microbialites, microfossils, and early multicellular organisms indicative of the rapidly increasing complexity of the biosphere at the very end of the Ediacaran period. The paleobiological importance of the Bocaina Formation, in middle of the Corumbá Group and dated at about 560 Ma, lies in its diversity of microbialites and its record of a significant phosphogenesis event with associated putative \"vase-shaped microfossils\", similar to testate amoebae, interpreted as early protistan heterotrophs. Th ese fossils, as well as similar forms recognized in other geologic units in the world precede the record of the explosion of macroscopic multicellular skeletal organisms (Cloudina, Corumbella) in the overlying Tamengo Formation (543 Ma). The morphology of microbialites provides evidence of local sea level variation during deposition of the Bocaina Formation. Morphological and chemical analyses of the microfossils using optical and scanning electron microscopy, EDS and Raman spectroscopy helped clarify the biological nature of these objects and thereby contribute to the understanding of the importance of the Bocaina Formation the evolution of late Ediacaran life in the Corumbá Group.

RésuméEn raison des spécificités relatives à la formulation des bétons autoplaçants (BAP) et en particulier ceux concernant leur volume élevé en pâte et la présence d'ajouts et substituts minéraux en grande quantité, leur comportement à l'état frais et à l'état durci ainsi que leur durabilité sont fortement influencés par ces deux paramètres.Certains sédiments traités acquièrent des propriétés pouzzolaniques et peuvent être utilisés en tant qu'ajouts ou substituts au ciment. Ceci peut faire de la technologie des bétons une voie privilégiée pour leur valorisation.La présente étude vise à apporter une contribution à la valorisation de la vase traitée du barrage de Chorfa et de Fergoug, (situé à l'ouest algérien) en tant que substitut minéral partiel au ciment CPA CEMI 42.5 dans la composition des mortiers et des bétons autoplaçants. Il s'agit de comparer l'influence de l'incorporation de cette vase calcinée à celle de la pouzzolane naturelle de Béni-Saf (situé, également à l'ouest algérien) dans les BAP sur leurs caractéristiques physico-mécaniques et sur leur durabilité à court, moyen et long terme.L'étude est menée sur quatre BAP, le premier à base de 20 % de pouzzolane naturelle de Béni-Saf (BAP-PZ), le deuxième et le troisième incorporant 20 % de la vase calcinée issue des sédiments de dragage du barrage de Fergoug (BAP-VF) et de celui de Chorfa (BAP-VC) et enfin un BAP témoin sans ajouts pour le besoin de comparaison.Outre l'intérêt économique que présentent les BAP à base de la vase calcinée, notre étude a montré que ces derniers représentent des performances très comparables à celles obtenues sur des BAP à base de pouzzolane naturelle (BAP-PZ).En effet, Concernant les résistances à la compression, notre étude indiquent que les BAP à base de vase ((BAP-VC) et (BAP-VF)) présentent les meilleurs résultats notamment à long terme.Les résultats des essais de l'attaque acide (HCl et H2SO4), l'attaque sulfatique (Na2SO4 et MgSO4) et de carbonatation accélérée, montrent que la vase calcinée a une influence sensiblement meilleure que celle de la pouzzolane sur les propriétés physico-mécaniques et la durabilité des bétons dans lesquels elle est incorporée.Mots clés : Barrage de Chorfa - Barrage de Fergoug –Vase calcinée – pouzzolane – BAP à base de vase – BAP à base de pouzzolane – Résistances mécaniques –Durabilité. / AbstractBecause of the specificities of self-compacting concrete (SCC), especially regarding their high volume paste content and the presence of large amounts of mineral admixtures and substitutes, the behavior in fresh and hardened state and the durability of these concretes are strongly influenced by these two parameters.Some treated sediments acquire pozzolanic properties and can be used as additions orsubstitutes to the cement. This possibility makes of concrete technology a privileged way of enhancement.The present study aims to contribute to the enhancement of the treated mud of Chorfa and Fergoug dam (situated in west of Algeria) as a mineral partial substitute for CPA CEMI 42.5 cement in the composition of an economic and preferment mortars and self-compacting concretes. The aim is to compare the influence of the incorporation of this calcined mud to the natural pozzolana of Beni Saf (situated, also in west of Algeria) in (SCC) on their physical, mechanical behavior and their durability of these concretes in short, medium and long term.The study was conducted on four SCCs, the first based on 20% natural pozzolana Beni Saf (SCC-PZ), the second based on 20% of the calcined mud of Fergoug dam (SCC-VF) and of Chorfa dam (SCC-VC) and a control SCC without additions to the need for comparison .Apart from the economic interest of the SCCs based on calcined mud, our study showed that these concretes have comparable performances to that obtained on SCC based on natural pozzolana (SCC-PZ).In fact, concerning compressive strengths, our study indicate that the SCC with calcined mud ((SCC-VC) and (SCC-VF)) present the best results especially at long termThe results of the different following tests: the acid attack (HCl and H2SO4), carbonation and sulphate attack (Na2SO4 and MgSO4) show that the calcined mud has an influence roughly better than the natural pozzolana on the physic - mechanical behavior and durability of the SCC which it is incorporated.Key words: Dam of Chorfa – Dam of Fergoug – Calcined mud – Pozzolana – SCCcontaining mud - SCC containing pozzolana – Mechanical strength –Durability.

The artist discusses the background, ideas, and work entitled Archetypes in Clay, for the completion of her Bachelor of Arts Degree and undergraduate research for the Fine and Performing Arts Scholar program at East Tennessee State University. The artist used this development of work to explore personality types, and how they can be portrayed through clay vessels. In particular, the artist shows her work, how she created the vessels, the testing involved, and the struggles she faced. Archetypes is the focus behind the concept of this project. Her work includes four ceramic vessels, created with clay and finished with glaze. The artist cites Carl Jung, Isabel Briggs-Myers, and NERIS Analytics Limited as important research in this project.
