Alterations of Na, K and Rb concentrations in Mycenaean pottery and a proposed explanation using X-ray diffraction

One of the most important reference groups for Mycenaean pottery is the Mycenae/Berbati (MB). In several studies, a second group has been identified (MBKR). The chemical compositions were similar to MB, but with important differences in the Na, K and Rb contents. The present study suggests that these differences are due to selective alteration and contamination processes that are indirectly determined by the original firing temperature. Therefore, groups MB and MBKR should be considered as a single reference group.

Technology transfer at the periphery of the Mycenaean world: the cases of Mycenaean pottery found in central Macedonia (Greece) and the Plain of Sybaris (Italy)

The study of technology transfer in pottery production to the periphery of the Mycenaean world has been addressed by considering two different areas, southern Italy and central Macedonia. Technological features such as ceramic paste, decoration and firing have been determined for different ceramic groups established according to provenance criteria. The studies of technology and provenance have been performed following an archaeometric approach, using neutron activation analysis, petrographic analysis, X-ray diffraction and scanning electron microscopy. The results have revealed the existence of two different models. On the one hand, southern Italy seems to exhibit a more organized pottery production, which follows a Mycenaean-like technology, while in central Macedonia production is probably more varied, being based in part on the technology of the local tradition.

Jehasse, Jean et Laurence (2001): Aléria. Nouvelles données de la nècropole.

La publicación por Jean y Laurence Jehasse en 1973 de la obra La Nécropole préromaine d'Aléria: 1960-1968 constituyó un hito en la historia de la investigación protohistórica en el ámbito del Mediterráneo. Junto a la necrópolis de La Spina (Italia), Aléria constituyó un punto de referencia clave para el estudio de las influencias de la sociedad colonial greco-focea sobre las comunidades indígenas en Córcega y, por extensión, en el Mediterráneo occidental, así como un corpus de consulta y análisis inexcusable para la identificación de las tipologías materiales de origen griego en la esfera colonial y comercial del extremo Occidente. Recordemos que, en esa fecha, los investigadores en la península Ibérica trabajaban esencialmente a partir de las publicaciones de J.D. Beazley (que no recogían la problemática de las series peninsulares) y, muy especialmente, con la obra Las cerámicas griegas en la península 1bérica de Gloria Trías, aparecida en 1968. Cabría esperar hasta 1977, en que Marina Picazo publicó Las cerámicas áticas de Ullastret, para contar con una monografía específica de las producciones griegas en un yacimiento ibérico.

Possibilitats i limitacions en l'estudi arqueomètric de les produccions ceràmiques ebusitanes

L'illa d'Eivissa, considerada com a una unitat, ha estat una de les arees productores de ceritrnica més importants de la Mediterrama occidental, especialment des d' epoca púnica fins a epoca tardorromana. Els estudis arqueometrics perrneten obtenir dades sobre la tecnologia de producció d' aquestes ceritrniques que enriqueixen els coneixements que actualment en tenim d' elles. A més, aquests estudis ens permeten caracteritzar-les composicionalment. El present artiele mostra com aquesta caracterització no pot aportar dades de la composició de la ceritrnica eivissenca com a una unitat, sino que aporta dades sobre una diversitat de produccions dins d'Eivissa, permetent així conduir l' atribució de procedencia de la cerlunica a unitats menors que la propia illa. D' aquesta manera, el coneixement arqueologic que es té de la ceritrnica eivissenca es veu enriquit amb noves possibilitats que milloren sensiblement el nostre coneixement de les interrelacions socials i economiques que les ceritrniques reflecteixen.

Chemical and mineralogical alteration of ceramics from a Late Bronze Age kiln at Kommos, Crete: the effect on the formation of a reference group

The formation of reference groups comprises an important procedure in chemical provenance studies of archaeological pottery. Material from ancient kilns is thought to be especially suitable for reference groups, as it comprises a definite unit of past production. Pottery from the Late Minoan IA kiln excavated at Kommos, Crete was analysed in order to produce a reference group in this important area of Minoan ceramic production. The samples were characterized by a combination of techniques providing information on the chemistry, mineralogy and microstructure of the ceramic body. Initially, the study was unable to establish, in a straightforward manner, a chemical reference group. Different ceramic pastes and a range of selective alterations and contaminations, affected by variable firing temperatures and burial environment, were shown to be responsible for the compositional variability. Procedures are described to compensate for such alterations and the perturbations in the data that they produce.

Representações de suicidas míticos na cerâmica grega: séculos VII-IV A.C.

Com a presente dissertação temos por objectivo problematizar, através da iconografia, as representações de suicidas míticos na cerâmica grega (séculos VII-IV a.C.). O corpus da pesquisa é constituído por 40 vasos com imagens de onze figuras mitológicas: Ájax, Alceste, Antígona, Ariadne, Cassandra, Fedra, Ifigénia, Macária, Medeia, Orestes e Políxena. Das 40 imagens analisadas, três são do séc. VII a.C., cinco do séc. VI a.C., onze do séc. V a.C. e 21 do séc. IV a.C. A dissertação é dividida em onze capítulos, um para cada figura mitológica, nos quais debateremos as fontes, a evolução do mito e a iconografia associada.

MiAMP1, a novel protein from Macadamia integrifolia adopts a Greek key beta-barrel fold unique amongst plant antimicrobial proteins

MiAMP1 is a recently discovered 76 amino acid residue, highly basic protein from the nut kernel of:Macadamia integrifolia which possesses no sequence homology to any known protein and inhibits the growth of several microbial plant pathogens in vitro while having no effect on mammalian or plant cells. It is considered to be a potentially useful tool for the genetic engineering of disease resistance in transgenic crop plants and for the design of new fungicides. The three-dimensional structure of MiAMP1 was determined through homonuclear and heteronuclear (N-15) 2D NMR spectroscopy and subsequent simulated annealing calculations with the ultimate aim of understanding the structure-activity relationships of the protein. MiAMP1 is made up of eight beta-strands which are arranged in two Greek key motifs. These Greek key motifs associate to form a Greek key beta-barrel. This structure is unique amongst plant antimicrobial proteins and forms a new class which we term the beta-barrelins. Interestingly, the structure of MiAMP1 bears remarkable similarity to a yeast killer toxin from Williopsis mrakii. This toxin acts by inhibiting beta-glucan synthesis and thereby cell wall construction in sensitive strains of yeast. The structural similarity of MiAMP1 and WmKT, which originate from plant and fungal phyla respectively, may reflect a similar mode of action. (C) 1999 Academic Press.

Characterization of late antique and early medieval pottery production of the city of Braga and its territory

The fundamental goal we set ourselves when developing this study is to try to characterize, both technically and formally, ceramics made in the city of Braga and its territory from the initial moments of the Late Antiquity to the Middle Ages. Thus, we will focus on analyzing some own productions that appear attached to the phases of late antique occupation —ceramics of red engobes and late gray—, as well as in the early medieval containers identified in different archaeological interventions practiced in the Braga environment. Concretely, we will analyze the material from various excavations conducted recently at the Theatre in the solar number 20/28 and 36/56 from the Afonso Henriques Street and the former District Hostel as well as the church of São Martinho de Dume.
