Samples from nearly 800 Bronze Age pottery sherds from Euboea, Eastern Boeotia and Eastern Thessaly were analysed together with 9 raw clays from the same areas. The-analysis was carried out in an attempt to identify areas of pottery manufacture, to discover the origin of specific groups of pottery, to relate pottery to, raw clays and to see how far pottery compositions can be associated with, and predicted by, geology. The work was done on the same lines as earlier studies at the Oxford Laboratory and at the British School at Athens. The main analytical technique used was therefore optical emission spectroscopy. Some 25% of the total number of sherds were also analysed by atomic absorption spectrophotometry so that the results obtained by the two techniques could be compared. The interpretation of the results was facilitated by the use of, computer program packages for cluster and discriminant analysis. Both optical emission and atomic absorption analysis resulted in broadly similar groupings although the absolute concentrations were not directly comparable. The groupings obtained after atomic absorption analysis had the narrower concentration ranges. Nine elements were measured by both techniques but in atomic absorption potassium was added and proved; useful as an additional discriminant. Six composition groups were distinguished from the data. One of them was identified as Euboean, 2 as Boeotian and 3 as coming from different regions of Thessaly. The greatest movement of pottery within these areas was from Euboea to Thessaly. No composition group which originated from outside these regions was identified. Six of the 9 raw clays were associated with the prevailing composition group in the area from which they came. It was not possible to predict trends in pottery composition by examination of the local geology.

This dissertation measures the extent of relationship between production, processing and marketing channels of fig products in Turkey for the period 1971-2003. We first provide a detailed analysis of world and Turkish fig products market. We then estimate the own price and cross price elasticities of fig products in Turkey by using simultaneous systems. The results imply that the demand facing Turkish dried fig processors is inelastic. Moreover also the producer-level dried fig price elasticity has inelastic structure. The study also finds evidence of a complementary structure between fig products apart from fresh fig.

Espécies patogênicas apresentam mecanismos capazes de contornar as barreiras de defesa do hospedeiro, facilitando sua disseminação e proliferação nos tecidos invadidos. Cepas resistentes aos antimicrobianos disponíveis surgem diariamente, por isso, é relevante encontrar métodos alternativos para controla-las. Produtos de plantas medicinais vem sendo investigados para essa finalidade. No presente estudo, foi avaliada a capacidade do extrato de C. longa em controlar infecções in vitro por S. aureus, P. aeruginosa e C. albicans em macrófagos murinos (RAW 264.7). Para isto, foram aplicadas as concentrações inibitórias mínimas (CIM) do extrato vegetal nas infecções e por meio de análise da fagocitose foi analisado a contribuição delas para a eliminação destes micro-organismos. A viabilidade dos macrófagos foi analisada por meio de teste colorimétrico com corante vermelho neutro. Foram checadas a produção de citocinas inflamatórias (IL-1β, IL-6, TNF-α e IL-10) e óxido nítrico (NO), por ELISA e com reagente de Griess, respectivamente. Os resultados foram analisados por ANOVA e Tukey’s Test (P ≤ 0.05). Foi verificado que o extrato de C. Longa auxiliou de maneira efetiva os macrófagos na fagocitose dos micro-organismos avaliados, apresentando reduções significativas de unidades formadoras de colônia por mililitro (UFC/mL), e atuou mediação da síntese de citocinas e NO. Os macrófagos apresentaram-se viáveis durante a infecção. Desta forma, foi constatado que o extrato de C. longa foi capaz de auxiliar in vitro os macrófagos na eliminação de S. aureus, P. aeruginosa e C. albicans, além de proporcionar efeito imunomodulador na síntese de IL-1β, TNF-α, IL-10 e NO, no intuito de controlar as infecções microbianas in vitro.

Neste contexto, o presente trabalho teve como objetivo caracterizar argilas provenientes de jazidas do município de Cubati-PB, visando estabelecer seus usos adequados como matérias-primas cerâmicas. Para tanto, as matérias-primas foram submetidas às seguintes técnicas de caracterizações: física, química, mineralógica e térmica. Posteriormente, foram preparados corpos de prova por prensagem uniaxial a 19 MPa, estes foram secos em estufa a 110°C, e submetidos a queima nas temperaturas de 750°C, 850°C, 950°C e 1150°C. Em seguida determinadas as propriedades físico-mecânicas: retração linear de queima (RLq), absorção de água (AA), densidade aparente (DAp), porosidade aparente (PA) e módulo de ruptura à flexão (MRF). As argilas A, B e C são adequadas para uso em cerâmica branca e a argila D para cerâmica vermelha. E todas as argilas contém composição mineralógica adequada para uso em cerâmica vermelha. / In recent years, new clays deposits have been discovered in the state of Paraiba, the characterization of these deposits is of fundamental importance to establish the best industrial usage. In this context, the aim of this study was characterized clays in the municipality of Cubati-PB, to establish their appropriate uses as ceramic raw materials. Therefore, the raw materials were subjected to the following characterization techniques: physical, chemical, mineralogical and thermal. Later, specimens were prepared by uniaxial pressing at 19 MPa, before dry at 110°C, and submitted to firing at temperatures of 750°C, 850°C, 950°C and 1150°C. It were determined the physical and mechanical properties: linear firing shrinkage (LFS), water absorption (WA), apparent density (DAp), apparent porosity (PA) and flexural modulus of rupture (MRF). The clays A, B and C are suitable for use in white ceramic and D to red ceramic. And all the clays contain adequate mineralogical composition for use in red ceramic.
