Castor fiber na gruta do Caldeirão. Existência, distribuição e extinção do castor em Portugal

Beaver only had been found in Portugal in a Chalcolithic locality, the Vila Nova de S. Pedro castrum. It has now been identified in the Upper Paleolithic (Solutrean) from Gruta do Caldeirão, near Tomar. The species has been found recently at «Gruta do Almonda»; 4 teeth were collected in bed C, older than a Solutrean sequence (see Anexo for details). The species seems to have been rare, as it was also the case with portuguese Miocene Castoridae Enroxenomys minutus and Chalicomys jaegeri. If account is taken of the presence in the Middle Ages until Castille of words meaning beaver (relared to the popular latin Fiber/Biber), it is obvious that these animais still existed then. Such nouns were largely predominant over rhe rather erudite latin (greek deríved) words as Castor,-óris and derived ones, as it could be expected. This allowed us to recognize that veiro should be the corresponding word with Fiber affinities in archaic portuguese. It was previously supposed to mean only expensive furs then imported into Portugal. Indeed it was also a zoonym. Anywày, beaver should be scarce by XIIIth century since it is not included in the quite detailed price list imposed by the «Lei da Almotaçaria» from December 26, 1253 (see Quadro II). Toponyms in veiro and derived words (fig. 2; Quadro III) (plural, feminines, diminutives, inhabited places) give a resrrictive view of rhe Middle Age distribution. Some of them are certainly older than Portugal itself (firsr half of XIlth cenrury); others existed by the XIVth century bur were probably older. Some rare toponyms seem to be derived from the erudite latin Castor,-óris. Nothing suggests that these words were still in use as zoonyms during the Middle Ages. All toponyms are located in regions near rivers and other freshwaters ecologically suitable for beavers, so we can approximately retrace its former, Middle Age disrribution in Portugal (fig. 2; Quadro III). Most of them are locared in the Center-West and Northwest of Portugal, with a suitable c1imate (rainfall in general over 800 mílimerers per year); the only sure geographical exception is Veiros, in Alto Alentejo province, in a region with comparable precipitations and less dry climate conditions than mosr of the territories South of rhe Tagus. There are less and less of these toponyms towards rhe South and the inner part of the country, and they are enrirely lacking in all drier regions from Trás-os-Montes, Beira, Alentejo beyond Tagus' basin, and in Algarve. Nothing suggests beavers lived there, No post-medieval toponym is known, nor any reference after middle XVth century. No such locality was at, or close by to, any frontier. Hence the hypothesis of veiro (et al.} as meaning but points where expensive furs (supposedly known as veiros in general but without c1early saying from what animal they were obrained from) is to be discarded. During the Middle Ages, beaver discriburion concerned all the main river basins from Minho to Tagus ones. Quite rarefied in rhe XIIIth, the beavers may have disappeared from Portugal during the XVth century. Ecological requiremenrs restricted their former distriburion. Vulnerability to natural causes (i.e., severe drought) and to human pressure may have accounted heavily for this species' extinction. Last (1446) reference for Portugal known to us suggests the species was by then almost extinct.

Antropologia Funerária e Paleobiologia das Populações Pós-Medievais Portuguesas: Os Casos de Nossa Senhora da Anunciada e Espírito Santo

As desigualdades sociais na saúde constituem a problemática abordada nesta dissertação, tendo sido escolhidas para explorar esta questão duas séries esqueléticas – igreja de Nossa Senhora da Anunciada (Setúbal) e capela do Espírito Santo (Loures) – cronologicamente enquadradas no período pós-medieval, entre os séculos XVI e XIX, e cujos indivíduos apresentavam estatutos socioeconómicos diferenciados. Na concretização deste objectivo foi realizada uma primeira abordagem que incidiu no estudo integral – contexto funerário e Paleobiologia – das respectivas séries. Do manancial de resultados obtidos foram seleccionados e explorados na segunda abordagem indicadores de estatuto social e de estatuto biológico (ou esqueléticos de stress fisiológico) capazes de responder à problemática enunciada, procurando demonstrar-se que as desigualdades sociais podem actuar sobre factores fundamentais ao desenvolvimento normal e saúde dos indivíduos, manifestando-se, consequentemente, de forma diferencial entre indivíduos de estatutos socioeconómicos contrastantes. A caracterização geral do contexto funerário revelou que no interior da igreja de N. Sra. da Anunciada, localizada no bairro do Troino, habitado por um segmento da população socialmente mais desfavorecido, registaram-se 93 inumações primárias e 155 secundárias, as quais foram realizadas em covas abertas no subsolo e revelando a quase ausência de espólio votivo e de caixão. Por outro lado, na capela do Espírito Santo foram exumadas 46 inumações primárias e 30 secundárias que foram exclusivamente encontradas em criptas, tendo os indivíduos sido inumados em caixão e identificando-se, igualmente, a presença de espólio votivo associado. A documentação histórica refere o nome de mecenas e benfeitores do respectivo convento com direito a sepultura na sua capela. Na caracterização paleobiológica geral foram revelados os perfis biológicos básicos, tendo sido identificados indivíduos de ambos os sexos e diferentes classes etárias, constatando-se em ambas séries esqueléticas a predominância de indivíduos do sexo feminino. A análise morfológica evidenciou os caracteres discretos e métricos, bem como a estatura dos indivíduos, sendo esta última, igualmente, referida no estudo das desigualdades sociais. Por fim, o estudo paleopatológico revelou a presença de diversas alterações dentárias e ósseas, incluindo condições enquadradas nos indicadores esqueléticos de stress fisiológico. Na segunda abordagem que se centrou no objectivo específico desta investigação, os indicadores de estatuto social – local de inumação, caixão e espólio votivo – mostraram uma associação dos indivíduos com o seu estatuto socioeconómico clara e inequívoca, enquanto os indicadores esqueléticos de stress fisiológico – crescimento, estatura, cáries, perda de dentes ante mortem, hiperostose porótica, cribra orbitalia, hipoplasias lineares do esmalte dentário, formação de osso novo bilateral nas tíbias, fracturas, osteoartrose, discartrose, alterações nas áreas das enteses e DISH – revelaram que a sua interpretação é muito complexa. Concluiu-se que a interpretação das desigualdades sociais na saúde com base em indicadores de estatuto biológico deve ser prudente, já que não é evidente uma associação ii directa com o estatuto socioeconómico dos indivíduos. Esta investigação corroborou a informação histórica e arqueológica que permite aludir ao estatuto socioeconómico dos indivíduos destas séries esqueléticas, mas a associação deste estatuto a uma saúde diferenciada entre grupos revelou-se inconclusiva.

Exemplo de vulcanismo tardio em Portugal- rocha ígnea post-Miocénico inferior (Figueira-Algarve)

A small outcrop of an igneous rock (basanite) was observed in 1971 at Figueira-Mexilhoeira Grande-Algarve, enclosed by Miocene limestone and showing clear evidente of low grade thermal effects along the contact with the igneous mass. This is in agreement with F. L. Pereira Sousa who was the first geologist to admit (1917) the existence of Miocene igneous rocks in Algarve although subsequently they were not possible to localize. This work reports studies on petrography and chemical composition of this basanite and describes the evidence of the thermal effects upon the surrounding calcareous rocks. This well localized small outcrop represents an igneous rock more modern than the basaltic complex of Lisbon, hitherto assigned to the Eocene in age and recently ascribed to the Upper Cretaceous and until now considered the most recent manifestation of volcanic activity in Portugal. However this does not exclude the possibility of existence of even more modem igneous rocks in Algarve region.

POST-PROCESSING TECHNIQUES SUITABILITY FOR MESOLEVEL FREE BOUNDARY FLOWS

Reliable flow simulation software is inevitable to determine an optimal injection strategy in Liquid Composite Molding processes. Several methodologies can be implemented into standard software in order to reduce CPU time. Post-processing techniques might be one of them. Post-processing a finite element solution is a well-known procedure, which consists in a recalculation of the originally obtained quantities such that the rate of convergence increases without the need for expensive remeshing techniques. Post-processing is especially effective in problems where better accuracy is required for derivatives of nodal variables in regions where Dirichlet essential boundary condition is imposed strongly. In previous works influence of smoothness of non-homogeneous Dirichlet condition, imposed on smooth front was examined. However, usually quite a non-smooth boundary is obtained at each time step of the infiltration process due to discretization. Then direct application of post-processing techniques does not improve final results as expected. The new contribution of this paper lies in improvement of the standard methodology. Improved results clearly show that the recalculated flow front is closer to the ”exact” one, is smoother that the previous one and it improves local disturbances of the “exact” solution.

Post-processing Techniques in Free Boundary Flows during Liquid Composite Moulding Processes

Post-processing a finite element solution is a well-known technique, which consists in a recalculation of the originally obtained quantities such that the rate of convergence increases without the need for expensive remeshing techniques. Postprocessing is especially effective in problems where better accuracy is required for derivatives of nodal variables in regions where Dirichlet essential boundary condition is imposed strongly. Consequently such an approach can be exceptionally good in modelling of resin infiltration under quasi steady-state assumption by remeshing techniques and with explicit time integration, because only the free-front normal velocities are necessary to advance the resin front to the next position. The new contribution is the post-processing analysis and implementation of the freeboundary velocities of mesolevel infiltration analysis. Such implementation ensures better accuracy on even coarser meshes, which in consequence reduces the computational time also by the possibility of employing larger time steps.

Designing a technology assessment post-graduation programme: experiences, limits and needs

The post-graduation in the field of Technology Assessment (TA) is recent and that are several and different ways to be organised. Most experiences are related with the Masters diplom level (2nd cycle of graduation in high education). Just one in PhD level is explicit in the field of TA, and some other PhD courses include also TA topics in their programme structure. In this chapter we will analyse the problems related with the design of a post-graduation (MA, MSc or PhD) programme in the field of TA using as reference some international experiences. Hereby, the main conclusion seems to address labour market needs in the specialised knowledge of TA, of technology management or technology innovation. In this sense TA should be included as “minor” into post-graduation courses which may range from engineering disciplines to social sciences. As a graduation programme it can fill an expertise gap between technicians, engineers, scientists and the strategic decision makers or policy makers.
