    Die Konstruiertheit und Unzuverlässigkeit der Erinnerung wird heute in der kulturwissenschaftlichen Gedächtnisforschung nicht bestritten. Aber in Rayk Wielands Roman Ich schlage vor, dass wir uns küssen ist die Erinnerung buchstäblich eine Erfindung oder, genauer gesagt, sie ist das Resultat einer phantasievollen Auslegung und "fehlgeleiteter Schnüffelphilologie" (Reents 2009). Der Träger des individuellen Gedächtnisses ist in diesem Fall nicht das individuelle Gehirn, sondern es sind die Stasi-Akten, und seine Stütze ist eine Erinnerungspolitik, die unbedingt Opfer und Heroen braucht, um ihre Vergangenheitsrekonstruktion zu legitimieren

    No momento de criação de uma ideia, assim como no desenvolvimentode um projecto, vários factores vão influenciando esse processo.O mesmo acontece quando se experiencia uma obra construída. Apercepção do espaço é condicionada por acontecimentos externos aoindividuo, mas também pelo passado experimentado deste. Estes doismomentos distintos, produção e experimentação, para além de teremem comum influências pessoais ou externas, também se influenciammutuamente. Todas as experiências espaciais vividas no passado, boas oumás, consciente ou inconscientemente, surgem no momento de criação.Por outro lado, a forma como o projecto é pensado e produzido terá umpapel determinante no modo como as pessoas que experimentam a obraconstruída percepcionam o espaço. E, por sua vez, se o visitante for umarquitecto, esta experiência irá influenciar futuras criações. Percebendoos factores que estão por detrás do processo mental de criação e experimentação,poderá ser possível ao arquitecto controlar os seus impulsospessoais, assim como os movimentos e sensações do futuro habitante.While creating an idea, as during the development of a project,several factors will influence the process. The same will happen whileexperiencing a building. The perception of space is conditioned byexternal events to the user, but also by the past he experienced. Thesetwo different moments, production and experimentation, beyondhaving in common personal or external influences, also influence eachother. All spatial experiences lived in the past, good or bad, consciouslyor unconsciously, arise at the moment of creation. On the otherhand, the way the project is thought through and designed will havea major role in how people, who experience the built work, perceivethat space. And in its turn, if the visitor is an architect, this experiencewill influence future creations. While understanding the factors thatare behind the mental process of creation and experimentation, itmight be possible for the architect to control his personal impulses,as well as the movements and sensations of the future inhabitant

Although the presence and infectivity of SARS-CoV-2 in aerosol are now acknowledged, the underlying circumstances for its occurrence are still under investigation. The contamination of domiciliary environments during the isolation of SARS-CoV-2-infected patients in their respective rooms in individual houses and in a nursing home was investigated by collecting surface and air samples in these environments. Surface contamination was detected in different contexts, both on high and low-touch surfaces. To determine the presence of virus particles in the air, two sampling methodologies were used: air and deposition sampling. Positive deposition samples were found in sampling locations above the patient's height, and SARS-CoV-2 RNA was detected in impactation air samples within a size fraction below 2.5 μm. Surface samples rendered the highest positivity rate and persistence for a longer period. The presence of aerosolized SARS-CoV-2 RNA occurred mainly in deposition samples and closer to symptom onset. To evaluate the infectivity of selected positive samples, SARS-CoV-2 viability assays were performed, but our study was not able to validate the virus viability. The presented results confirm the presence of aerosolized SARS-CoV-2 RNA in indoor compartments occupied by COVID-19 patients with mild symptoms, in the absence of aerosol-generating clinical procedures.This Project has been partially supported by Portuguese national funds via Fundação para a Ciência e a Tecnologia—Ministério da Ciência, Tecnologia e Ensino Superior (FCT-MCTES), under Project 679 Research4Covid19, UIDB/04539/2020 and UIDP/04539/2020.info:eu-repo/semantics/publishedVersio

    ATLANTIC EPIPHYTES: a data set of vascular and non-vascular epiphyte plants and lichens from the Atlantic Forest

    Get PDF
    Epiphytes are hyper-diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non-vascular plants (including hemiepiphytes), and lichen epiphyte species occurrence and abundance; (2) describe the epiphyte distribution in the Atlantic Forest, in order to indicate future sampling efforts. Our work presents the first epiphyte data set with information on abundance and occurrence of epiphyte phorophyte species. All data compiled here come from three main sources provided by the authors: published sources (comprising peer-reviewed articles, books, and theses), unpublished data, and herbarium data. We compiled a data set composed of 2,095 species, from 89,270 holo/hemiepiphyte records, in the Atlantic Forest of Brazil, Argentina, Paraguay, and Uruguay, recorded from 1824 to early 2018. Most of the records were from qualitative data (occurrence only, 88%), well distributed throughout the Atlantic Forest. For quantitative records, the most common sampling method was individual trees (71%), followed by plot sampling (19%), and transect sampling (10%). Angiosperms (81%) were the most frequently registered group, and Bromeliaceae and Orchidaceae were the families with the greatest number of records (27,272 and 21,945, respectively). Ferns and Lycophytes presented fewer records than Angiosperms, and Polypodiaceae were the most recorded family, and more concentrated in the Southern and Southeastern regions. Data on non-vascular plants and lichens were scarce, with a few disjunct records concentrated in the Northeastern region of the Atlantic Forest. For all non-vascular plant records, Lejeuneaceae, a family of liverworts, was the most recorded family. We hope that our effort to organize scattered epiphyte data help advance the knowledge of epiphyte ecology, as well as our understanding of macroecological and biogeographical patterns in the Atlantic Forest.

    O romance Livro de José Luís Peixoto: uma narrativa de pós-memória

    No full text
    O romance Livro (2010), diz o seu autor, “pode ser apontado como o mais autobiográfico dos meus livros. Paradoxalmente é o menos autobiográfico, no sentido em que os acontecimentos factuais desse romance passam-se num tempo em que eu ainda não era nascido” (Peixoto 2010). Com efeito, o romance Livro narra uma história que não é sua, mas dos pais: a história da emigração para França nos anos 60. O Livro constitui assim um trabalho de pós-memória (Hirsch 1997), transmitida por meio de narrativas (familiares), imagens e comportamentos e consolidada pelos afectos. A reconstrução imaginativa dessa experiência permitiu inscrever a memória individual na memória cultural e consequente disseminação. Por último, a tradução e recepção do romance em geografias e culturas muito distintas indicia a universalidade da experiência migratória narrada em Livro e possibilita a partilha de memórias entre comunidades entre as quais não existem laços familiares, éticos ou nacionais. Emerge deste modo a ideia de uma experiência comum, geradora de empatia e de memória transcultural (Erll 2011, Crownshaw 2014). O presente trabalho tem como objectivo a análise dos contornos da experiência migratória nos seus contextos sociais e culturais e as estratégias que permitiram traduzir esteticamente o passado violento em Livro. E porque as emoções são indispensáveis na formação e transmissão da memória, aquelas serão igualmente consideradas.The novel Livro (2010), says the author, “may be pointed out as the most autobiographical of my books. Paradoxically, it is the less autobiographical, since it tells a story that takes place in a time before I was born. In fact, Livro tells the story, that is not mine, but of my parents: the story of Portuguese migration to France in the 60s. Peixoto’s novel is in this way a work of postmemory (Hirsch 1997), mediated by familiar narratives, images and attitudes and cemented by affection. The imaginative reconstruction of the personal experience allows to inscribe the individual memory into cultural memory and its consequent dissemination. Lastly, the novel’s translation and reception in very different geographies and cultures suggest the universality of the migratory experience narrated in Livro and enables the sharing of memories beyond familiar, ethnic or national bonds. It emerges, in this way, the idea of a common experience, which paves the way to empathy and transcultural memory (Erll 2011, Crownshaw 2011). This essay aims to analyze the contours of the migratory experience in its social and cultural contexts, integrating in this analysis the strategies that permitted to translate aesthetically the violent past in Livro. And since emotions are crucial to the construction and transmission of memory, those will be also considered

    Hierarchical self-assembly of a reflectin-derived peptide

    Get PDF
    Reflectins are a family of intrinsically disordered proteins involved in cephalopod camouflage, making them an interesting source for bioinspired optical materials. Understanding reflectin assembly into higher-order structures by standard biophysical methods enables the rational design of new materials, but it is difficult due to their low solubility. To address this challenge, we aim to understand the molecular self-assembly mechanism of reflectin’s basic unit—the protopeptide sequence YMDMSGYQ—as a means to understand reflectin’s assembly phenomena. Protopeptide self-assembly was triggered by different environmental cues, yielding supramolecular hydrogels, and characterized by experimental and theoretical methods. Protopeptide films were also prepared to assess optical properties. Our results support the hypothesis for the protopeptide aggregation model at an atomistic level, led by hydrophilic and hydrophobic interactions mediated by tyrosine residues. Protopeptide-derived films were optically active, presenting diffuse reflectance in the visible region of the light spectrum. Hence, these results contribute to a better understanding of the protopeptide structural assembly, crucial for the design of peptide- and reflectin-based functional materials.ISSN:2296-264
