Imagem- documento. Refigurações do arquivo nos filmes de Filipa César Hito Steyerl e Harun Farocki

Esta tese analisa o conceito de imagem-documento na arte contemporânea através do comentário a um conjunto de filmes, que têm em comum uma génese documental: A Cruz e a Prata (2010), de Harun Farocki, Cacheu (2010), de Filipa César e November (2004), de Hito Steyerl. Em primeiro lugar, é introduzido e definido o conceito de imagemdocumento e, em seguida, são identificadas as transformações a que o conceito de arquivo tem vindo a ser sujeito no contexto da arte contemporânea e, consequentemente, como é que esta transformação altera a noção de documento visual e a forma como este é recebido pelo espectador. A tese divide-se em três capítulos, sendo que no primeiro é feita uma abordagem ao conceito de imagem-documento relacionando o percurso que associa o documento ao espaço da arte com referências históricas; no segundo capítulo, é elaborado comentário individual dos filmes; e no terceiro é abordado o papel do documentário na arte contemporânea, bem como o conceito de “efeito de arquivo” e a sua relação com os filmes enunciados.

Analysis and Treatment of a male portrait in oil and a study of the size layer with reconstructions from Vibert’s recipe (1892)

This thesis project concentrated on both the study and treatment of an early 20th century male portrait in oil from Colecção Caixa Geral de Depósitos, Lisbon, Portugal. The portrait of Januário Correia de Almeida, exhibits a tear (approximately 4.0 cm by 2.3 cm) associated with paint loss on the right upper side, where it is possible to observe an unusually thick size layer (approximately 50 microns) and an open weave mesh canvas. Size layers made from animal glue remain subject to severe dimensional changes due to changes in relative humidity (RH), thereby affecting the stability of the painting. In this case, the response to moisture of the size layer is minimal and the painting is largely uncracked with very little active flaking. This suggests that the size layer has undergone pre-treatment to render it unresponsive to moisture or water. Reconstructions based on late nineteenth century recipes using historically appropriate materials are used to explore various options for modifying the characteristics of gelatine, some of which may relate to the Portrait’s size layer. The thesis is separated into two parts: Part 1: Describes the history, condition, materials and techniques of the painting. It also details the treatment of Januário Correia de Almeida as well as the choices made and problems encountered during the treatment. Part 2: Discusses the history of commercial gelatine production, the choice of the appropriate animal source to extract the collagen to produce reconstructions of the portrait’s size layer as well as the characterization of selected reconstructions. The execution of a shallow textured infill led to one publication and one presentation: Abstract accepted for presentation and publication, International Meeting on Retouching of Cultural Heritage (RECH3), Francisco Brites, Leslie Carlyle and Raquel Marques, ‘’Hand building a Low Profile Textured Fill for a Large Loss’’.

The morphology of the foregut of larvae and postlarva of Sesarma curacaoense De Man, 1892: a species with facultative lecithotrophy during larval development

Previous study on the resistance of larvae of Sesarma curacaoense submitted to starvation has revealed a facultative lecithotrophy during zoeal stages, but megalopa and first juvenile stages are exclusively feeding stages. In the present study, the gross morphology and fine structure of the foregut of S. curacaoense were investigated during larval, megalopa and first juvenile stages. The foregut of the zoea I show specific setae and a filter press apparently functional. The foregut undergoes changes in the zoea II (last larval stage) with increment of setae number, mainly on the cardiopyloric valve and complexity of the filter press. After metamorphosis to megalopa stage the foregut become rather complex, with a gastric mill supporting a medial and two lateral teeth well-developed. The foregut of the first juvenile is more specialized compared to the previous stage, showing similar characteristics of the decapod adults. These results provide further evidence of facultative lecithotrophic development in the larvae of S. curacaoense.

Meiose em Rhinocricus Padbergi Verhoeff, 1938

In the present paper the behaviour of the chromosomes in the spermatogenesis of the Myriapod Rhinocricus Padbergi Verhoeff, 1938 is studied. The primary spermatocytes are provided with 10 independent bivalents which separate normally giving rise to equivalent secondary spermatocytes. No indication of sex chromosomes has been found. Fusion of two bivalents or of four, two by two, has been observed, giving origin to secondary spermatocytes with 9 and 8 chromosomes respectively, in which fused chromosomes could be discovered. For analysing the facts the chomosomes of both, primary and secondary metaphases were separately counted from a total of 190 celis of four individuals and statistically treted. The X2-test gave insignificant results. Twenty chomosomes were counted in somatic tissues. The heterochròmatic parts of the leptotene threads were usually arranged in the periphery of the nucleus. In resting nuclei chromocenters can be observed in varyng number. Their chromosomal nature is revealed by the fact that when treated by KCÑ or KNOS they begin uncoiling.

Revision of the spider genus Pycnothele (Araneae, Nemesiidae)

The genus Pycnothele Chamberlin, 1917 is revised. The Brazilian species Pycnothele perdita Chamberlin, 1917, P. singularis (Mello-Leitão, 1934) and P. auronitens (Keyserling, 1891) are redescribed, diagnosed and illustrated. The females of P. auronitens and P. singularis are described for the first time and P. auripila (Mello-Leitão, 1946) from Uruguay, currently a junior synonym of P. auronitens, is revalidated. Pycnothele piracicabensis (Piza, 1938) is transferred to Rachias Simon, 1892, with which it shares the morphology of the sexual structures, restoring the original combination. Five new species are proposed for Brazil: Pycnothele rubra sp. nov., P. jatai sp. nov. and P. araraquara sp. nov., from state of São Paulo, P. arapongas sp. nov., from state of Paraná, and P. gauderio sp. nov., from state of Rio Grande do Sul. After this revision the genus includes ten Neotropical species. Maps with distribution of all species is presented for the first time and the occurrence of species of the genus is enhanced for the Brazilian state of Paraná.

Trematódeos monogenéticos (Polistomatas) da costa brasileira I. sobre Loimos scitulus sp. n. (Loimoidae) e Tagia ecuadori (Meserve, 1938) Sproston, 1946 (Diclidophoridae)

Em continuação aos estudos dos trematódeos monogenéticos da Coleção Helmintológica do Instituto Oswaldo Cruz, descrevemos no presente trabalho uma espécie do gênero Loimos MacCallum, 1917, Loimolinae Price, 1936, loimoidae Bychowsky, 1957 que consideramos nova para a ciência, e assinalamos nova ocorrência de Tagia ecuadori (Meserve, 1938) Sproston, 1946, Tagiinae Yamaguti, 1963, Diclidophoridae Najibina & Obonikova, 1971, no Atlântico Sul. Loimos scitulus sp. n. diferencia-se das outras espécies do gênero pelos seguintes caracteres: forma e estrututra do proaptor, oótipo grande, número de testículos, posição do poro genital, filamento do ovo e forma de opistaptor. Dentre as diferenças dadas Loimos scitulus sp. n. aproxima-se de L. salpinggoides pela estrutura do proaptor, de L. secundus pela posição do poro genital; de L. winteri pelo opistaptor. Quanto aos exemplares de Tagia ecuadori por nós estudados, apesar de ter sido evidenciada uma vagina, identificamos a esta espécie, por apresentar estruturas e medidas que se enquadram nas variações dadas pelos estudiosos do grupo.
