Stable isotope and multi-analytical investigation of Monte da Cegonha: A Late Antiquity population in southern Portugal

This study presents for the first time the diet of a Late Antiquity population in southern Portugal (Civitas of Pax Julia), from the Roman villa of Monte da Cegonha (predominantly 7th century CE). Stable isotope analysis (δ13C, δ15N, δ18O, 87Sr/86Sr) of human and faunal bone collagen and apatite was conducted in order to understand the influence of Roman subsistence strategies on the way of life of rural inhabitants of the area of Pax Julia and to explore their diet (types of ingested plants, amount of animal resources, terrestrial versus marine resources). X-ray diffraction (XRD) and Fourier transform infra-red spectroscopy (FTIR) analyses were used to determine the degree of bone diagenesis and assess the reliability of the bone stable isotopic composition for palaeodietary reconstruction. Anthropological analysis revealed a cariogenic diet, rich in starchy food and carbohydrates, in at least in two individuals based on the frequency of dental caries. Collagen and apatite carbon isotopic analysis suggested that C3 plants were the basis of the population's diet, complemented with some terrestrial meat and its by-products as reflected by the observed bone collagen nitrogen isotopic composition. Moreover, whilst the fairly low apatite-collagen spacing recorded in some skeletons (at around 4‰) may have been due to freshwater organisms intake, the relatively low nitrogen values observed indicate that this consumption did not occur very often, unless in the form of fresh fish of low trophic level or fish sauces. There were no significant differences in isotopic values depending on gender or burial type. Strontium and oxygen isotopic composition of bone apatite revealed a sedentary community, with the exception of a male individual who probably did not spend his childhood in Monte da Cegonha.

Contributo para a caracterização das raças serpentinas e charnequeira

Esta dissertação retoma um estudo com 49 cabras e 45 cabritos da raça Serpentina, 24 cabras e 28 cabritos da raça Charnequeira, exploradas em regime extensivo. Pretende ser um contributo para a caracterização destas raças. Com este objectivo calculou-se a fertilidade que foi de 92% nas duas raças e a prolificidade foi de 160% (62,5% partos duplos) na Serpentina e de 141% (57,1% partos duplos) na Charnequeira. A mortalidade dos cabritos, do nascimento até ao desmame, foi de 15,7%, na Serpentina e de 6,6%, na Chamequeira. Os pesos das cobrições ao parto, na Serpentina aumentaram 17% e 13,6% na Chamequeira, apresentando variações significativas na raça, mas não entre raças. Os cabritos de partos simples obtiveram maiores ganhos médios diários do nascimento ao desmame. Não houve variações significativas nos pesos entre machos e fêmeas. Analisaram-se 24 carcaças de cabritos, machos inteiros. O Rendimento Corrigido foi de 52% para as duas e a relação Músculo/Osso de 2,13 (Charnequeira) e 2,12 (Serpentina). O Índice Compacidade para a Charnequeira foi de 11,78 e 11,29 para a Serpentina, evidenciando esta melhor conformação. Definiram-se os seguintes cortes nas carcaças: I-Pá; II-Perna; III- Costela+Sela; IV-Aba; V-Pescoço. Analisou-se o músculo quanto à gordura, proteína, cálcio e fósforo. ABSTRACT: This dissertation retrieves a study involving 49 goats and 45 kids of Serpentina breed, 24 goats and 28 kids of Chamequeira breed exploited in an extensive management. It is intended as a contribution to the characterization of these breeds. To this end, various reproductive parameters were calculated. The fertility stood at 92% in both breeds and the prolificacy in the breed Serpentina was 160% (62.5% in twin births) and in the breed of Chamequeira was 141% (57.1% in twin births). We noted a mortality rate in kids from birth to weaning higher in the Serpentina breed (15.7%), while the Chamequeira breed recorded 6.6%. The evolution of the weights during the mating period to childbirth, increasing 17% in the Serpentina breed and 13.6% in Chamequeira breed. We noted significant variations in each breed, but not between each other. The kids resulting of simple birth had higher average daily weight gain from birth to weaning. We did not note significant variations of weight between males and females. We analysed the carcasses of 24 male kids. The corrected yield was 52% for both breeds and the muscle-bone ratio was 2,13 (Chamequeira) and 2,12 (Serpentina). The compactness index for the Chamequeira breed was 11.78 and 11.29 for the Serpentina breed, showing Serpentina breed had better conformation. We proposed the following cuts in the carcass: I-Shovel, II Leg, III- Rib +Sela, IV-Aba and V-Neck. We also analysed the muscle according to their fat, protein, calcium and phosphorus, aiming to show the dietary interest of this muscle.

Realidade histórica na narrativa de ficção angolana: Mayombe, de Pepetela o ministro, de Wanhenga Xitu o vento que desorienta o caçador, de A. Santos

Usando documentos oficiais, registos legislativos, memórias e outras fontes documentais escritas produzidos no período entre os anos 60 e início da década de 90 do século XX, o presente estudo procura estabelecer a relação entre a narrativa de ficção e a realidade histórica documentada. O procedimento metodológico consistiu no confronto de registos de factos da realidade nos referidos documentos com o mundo possível criado pelos escritores. A investigação centrou-se nos romances de três escritores angolanos (Pepetela, Wanhenga Xitu e Arnaldo Santos). Os resultados demonstram que os textos ficcionais escolhidos se estruturam a partir da matéria de extracção histórica. O produto da pesquisa contribui para legitimar o valor documental das obras escolhidas entre outras que fazem parte da narrativa de ficção angolana. O trabalho visa, também, uma finalidade didáctica: a explicação de textos de ficção narrativa que analisam momentos marcantes da história recente de Angola; HISTORICAL REALITY IN THE NARRATIVE OF ANGOLAN FICTION ABSTRACT: Using official documents, legislative records, memories, and other written documental sources produced in the period between the sixties and the early nineties of the XX century, this study seeks to establish a relationship between fiction narrative and historical reality. The methodological procedure consisted in the comparison of records of the facts in the aforesaid documents with a possible world created by the author. The research focuses on novels by three Angolan writers (Pepetela, Wanhenga Xitu, and Arnaldo Santos). The results indicate that the selected fictional texts are structured from topics relating to history. The research outcome contributes to legitimate the documental value of the Works selected amongst those forming part of the Angolan fiction. Furthermore, the research serves another didactic purpose: explaining narrative fiction texts that review defining moments of the recent history of Angola.

The marriage of João de Alarcão and Margarida Soares and the creation of a transnational Portuguese-Spanish nobility

The main aim of this chapter is to analyze the social and political effects of dynastic marriages between the Portuguese and Castilian-Aragonese crowns on the configuration of transnational, aristocratic families during the sixteenth and seventeenth centuries. To illustrate these questions we have chosen to follow the Soares de Alarcão family (known in Spain as Suárez de Alarcón) and the paths it took between the royal houses of Portugal and Castile for seven generations. The working hypothesis of the chapter is that the identity of the Iberian nobility during this era was characterized by a shared noble culture rather than by any particular features derived from the family’s land of origin. That assumption allows us to discuss whether the use of a particular language or culture indicates ties or political loyalties based on criteria of nationality, or, at the very least, place of birth. Therefore, this essay discusses the miscegenation of Iberian nobilities derived from dynastic marriages. It articulates the structural characteristics of this group and its political impact with the individual trajectories and historical contexts in which they developed. While these topics can be of interest for the comprehension of Portuguese early modern history, they can also help us to reflect more broadly on processes of identity construction.

Espanto: Adaptação de excertos do romance "As aventuras de joão sem medo" de José Gomes Ferreira para um espectáculo de formas animadas, duas actrizes e uma máquina de "encontar"

A partir de excertos do romance "As Aventuras de João Sem Medo" (publicado em 1963) de José Gomes Ferreira (1900-1985), criou-se um espectáculo para duas actrizes manipuladoras de bonecos, interagindo com uma máquina de cena. De início, identificaram-se no romance uma série de atmosferas e pequenas unidades de acção, que serviram de base para o guião do espectáculo orientado para um público heterogéneo. Partindo dos recursos existentes, procurou-se uma dramaturgia do texto com dois níveis de representação: o jogo entre as actrizes que, enquanto fadas competem entre si pelo uso da máquina de "encontar"; e o jogo entre os bonecos que, embora autónomo do ponto de vista narrativo, acaba por funcionar como a materialização do conflito entre as manipuladoras. Do texto para o teatro, assistimos ao espanto que nos provoca uma marioneta rebelde. /ABSTRACT: From excerpts of the "The Adventures of Fearless John" a romance (published in 1963) by Jose Gomes Ferreira (1900-1985), a show was created for two actresses I puppeteers who interact with an onstage prop. From the beginning, a series of different moods and small units of action were identified, and serve as the basis for the show oriented to a general audience. Trough the existing resources, two different levels of representation were found to dramatize the text: the interplay between the actresses who, while portraying fairies, compete for the use of the storytelling box; and the interplay between the puppets who, although they are independent from the narrative point of view, end up functioning as a materialization of the conflict between the puppeteers. From the text to the theatre, we witness the wonder that a rebellious puppet inspires.

O engenheiro Adriano Monteiro e a utilização do ferro na reconversão e refuncionalização de espaços em Évora: o caso do Palácio D. Manuel e dos Paços do Concelho

Resumo A partir da segunda metade do século XIX e XX assistiu-se à introdução de novos materiais, como o ferro fundido, o aço e o vidro, na remodelação ou construção de edifícios que procuravam dar resposta às novas necessidades de gestão urbana e de criação de espaços de lazer e sociabilidade. Nestas intervenções, que ficaram marcadas pela arquitectura do ferro, os engenheiros, grupo profissional detentor de competências técnicas que os habilitavam a trabalhar com estes materiais, tiveram um papel determinante. Na cidade de Évora a ligação entre a utilização de novos materiais e os engenheiros, é visível no papel que o Engenheiro Adriano Monteiro teve na reconversão do Palácio D. Manuel e na remodelação do edifício dos Paços do Concelho. Palavras-chave: Engenheiro, Arquitectura do Ferro, Évora, Palácio D. Manuel, Paços do Concelho Abstract From the second half of the nineteenth century onwards, there was the introduction of new materials, such as cast iron, steel and glass, in the remodeling or in the construction of buildings that sought to satisfy the new needs of urban management and the creation of leisure spaces and sociability. In these interventions that were marked by the iron architecture, the engineers, a professional group with technical skills that enabled them to work with these materials, played a decisive role. In the city of Évora this link between the utilization of new materials and engineers, is visible in the role that engineer Adriano Monteiro had in the conversion of the D. Manuel Palace and in the remodeling of the Town Hall building. Keywords: Engineers, Iron Architecture, Évora, D. Manuel Palace, City Hall
