Os poetas passam e os artistas ficam: Fernando Pessoa, influência e construção
Tese de doutoramento, Teoria da Literatura, Universidade de Lisboa, Faculdade de Letras, 2003Esta tese estuda os conceitos pessoanos de influência e construção, defendendo, por um lado, que todos os heterónimos maiores constituem reacções contra Teixeira de Pascoaes e, por outro, que Walt Whitman, Ralph Waldo Emerson e Edgar Allan Poe desempenham um papel mediador neste contexto.Abstract: This thesis studies Pessoa’s concepts of influence and construction, defending, on one hand, that all major heteronyms are reactions against Teixeira de Pascoaes and, on the other hand, that Walt Whitman, Ralph Waldo Emerson and Edgar Allan Poe play a mediative role in this context.Fundação para a Ciência e Tecnologia: concessão de uma Bolsa de Doutoramento (no âmbito do III Quadro Comunitário de Apoio do Fundo Social Europeu
O invisĂvel Hotel Ryugyong, representações do outro no romance Dentro do segredo, uma viagem na Coreia do Norte, de JosĂ© LuĂs Peixoto
Ler Dentro do segredo, Uma viagem na Coreia do Norte, de JosĂ© LuĂs Peixoto Ă© abrir uma porta para um mundo desconhecido, quase ignorado, como o pode ser a Coreia do Norte. O autor procura com esta obra mostrar como a literatura pode tomar conta de assuntos que remetem para a esfera polĂtica, sociolĂłgica e atĂ© antropolĂłgica, de forma a colocar em cena uma sociedade enclausurada, assim como um dos regimes ditatoriais mais fechados do mundo. A representação literária e geográfica da Coreia do Norte permite ao autor entrar na "casa do Outro" e perceber de que forma a visĂŁo de um ocidental sobre essa cultura pode contribuir para a construção do texto e de que forma o contacto com a mesma possibilita a desconstrução dessa visĂŁo sobre um dado lugar no mundo. Por outro lado, a escolha do paĂs Ă© a forma encontrada pelo autor de viver a sua aventura quixotesca, posto que o exĂlio momentâneo na Coreia do Norte, corresponde a um desejo profundo de busca de si e o encerramento numa sociedade tĂŁo fechada Ă© uma forma de se descobrir e de descobrir a sua pertença ao pequeno retângulo pintado a amarelo no globo terrestre encontrado numa escola coreana. A referĂŞncia a D. Quixote nĂŁo Ă© gratuita, dado que o livro, escondido numa mala, acompanha o autor ao longo da viagem e será o ponto de partida para uma reflexĂŁo sobre a realidade vivida e a realidade retĂłrica do regime de Pyongyang
Combining an HA + CU (II) site-targeted copper-based product with a pruning wound protection program to prevent infection with Lasiodiplodia spp. in grapevine
The genus Lasiodiplodia has been reported from several grape growing regions and is
considered as one of the fastest wood colonizers, causing Botryosphaeria dieback. The aim of
this study was to (i) evaluate the efficacy of Esquive®, a biocontrol agent, on vineyard pruning
wound protection, applied single or, in a combined protection strategy with a new site-targeted
copper-based treatment (LC2017), and (ii) compare their efficacy with chemical protection provided
by the commercially available product, Tessior®. For two seasons, protectants were applied onto
pruning wounds, while LC2017 was applied throughout the season according to the manufacturer’s
instructions. Pruning wounds of two different cultivars were inoculated with three isolates of
Lasiodiplodia spp. Efficacy of the wound protectants, varied between both years of the assay and
according to the cultivar studied but were able to control the pathogen to some extent. The application
of LC2017 did not show clear evidence of improving the control obtained by the sole application of
the other products tested. Nevertheless, LC2017 showed a fungistatic effect against Lasiodiplodia spp.,
in vitro, and has previously shown an elicitor effect against grapevine trunk diseases. Therefore, this
combination of two protection strategies may constitute a promising long-term approach to mitigate
the impact of Botryosphaeria diebackinfo:eu-repo/semantics/publishedVersio
Redes sociais em novos empreendimentos : o papel do Instagram na perspectiva de microempreendedoras do ramo da moda.
O trabalho apresenta a pesquisa realizada com microempreendedoras do ramo da
moda feminina para entender como elas enxergavam o papel do Instagram para suas
marcas. Com base nas quatro etapas propostas na metodologia do inbound marketing,
foram analisadas as possibilidades e limitações apresentadas pela mĂdia social para
cada empresa. Para isso, foram realizadas entrevistas semi-estruturadas de forma
remota com cada participante. Os resultados descreveram a perspectiva das
microempreendedoras sobre a atuação do Instagram nas quatro etapas, que se
mostrou eficiente principalmente para as empresas menos estruturadas. Todas as
quatro foram total ou parcialmente realizadas de maneira satisfatória através da
plataforma. Também foram percebidas as limitações que foram aparecendo conforme o
desenvolvimento e crescimento das empresas no mercado, como a etapa de fechar

Cylindrocarpon root rot: multi-gene analysis reveals novel species within the Ilyonectria radicicola species complex
Abstract Ilyonectria radicicola and its Cylindrocarpon-like
anamorph represent a species complex that is commonly
associated with root rot disease symptoms on a range of
hosts. During the course of this study, several species could
be distinguished from I. radicicola sensu stricto based on
morphological and culture characteristics. DNA sequence
analysis of the partial β-tubulin, histone H3, translation
elongation factor 1-α and nuclear ribosomal RNA-Internal
Transcribed Spacer (nrRNA-ITS) genes were employed to
provide further support for the morphological species
resolved among 68 isolates associated with root rot disease
symptoms. Of the various loci screened, nrRNA-ITS
sequences were the least informative, while histone H3
sequences were the most informative, resolving the same
number of species as the combined dataset across the four
genes. Within the Ilyonectria radicicola species complex,
12 new taxa are delineated occurring on a diverse range of hosts, the most common being Cyclamen, Lilium, Panax,
Pseudotsuga, Quercus and Vitis
Effect of the Combined Treatments with LC2017 and Trichoderma atroviride Strain I-1237 on Disease Development and Defense Responses in Vines Infected by Lasiodiplodia theobromae
Grapevine trunk diseases constitute one of the major problems for viticulture worldwide,
with Botryosphaeria dieback considered as one of the most important of these diseases. In this work,
we aimed to (i) evaluate the effect of the combination of two products, Esquive® (a Trichoderma-based
product) and LC2017 (a low-copper-based product), in the control of Lasiodiplodia theobromae, by
evaluating the internal lesion length caused by inoculation of this pathogen on greenhouse kept
grapevines of cvs Cabernet Sauvignon and Touriga Nacional and, (ii) investigating their elicitor
effect on plant defense responses, through the analysis of the expression of a set of genes. The
pathogen was always re-isolated from the infected tissues and was able to cause wood discoloration.
Touriga Nacional exhibited longer lesions than Cabernet Sauvignon, and the application of both
products did not appear to reduce lesion length when compared to LC2017 applied alone. The elicitor
effect of LC2017 on plant defense was confirmed by gene expression analysis, and no significant
differences were found between plants treated with LC2017 and with both products. Moreover, a
specific response related to the cultivar was verified, but this apparently unique interaction between
product, cultivar and pathogen remains to be further investigatedinfo:eu-repo/semantics/publishedVersio
Hyperacusis and stapes surgery: An observation in fifty patients after stapedotomy
Objective: To assess hyperacusis after stapedotomy and its possible influencing factors.
Study design: Prospective, interventional, and longitudinal study.
Setting: A tertiary referral center.
Patients: Fifty consecutive patients (35 females, mean age = 46.8 years).
Intervention: All patients underwent stapedotomy. The validated Portuguese version of the "Hyperacusis Questionnaire" (HQ) was administered before and two weeks and one month after surgery.
Results: No hyperacusis was reported by any patient before surgery. At two weeks after surgery, all patients experienced hyperacusis, with a mean HQ at 16.88 ± 6.54 (range 4-25). One month after surgery, hyperacusis had already resolved in most patients. Gender, preoperative presentation or surgeon had no influence on HQ scores (p > 0.05). Patients with previous contralateral stapedotomy showed lower HQ scores (p = 0.001). Audiological parameters improvement measured at one month after surgery (PTA, SRT and contralateral SRT) were associated with HQ higher scores.
Conclusion: This study confirms that hyperacusis is a common complaint after stapedotomy that usually resolves in one month after surgery. The HQ highest scores were registered among patients with the highest audiological gain after surgery. This suggests that hyperacusis may be a positive prognostic factor for audiological success after stapedotomy.info:eu-repo/semantics/publishedVersio

Contribution for a better understanding of grapevine fungal trunk diseases in the Portuguese DĂŁo wine region
Summary. Esca and Petri disease, two of the most important fungal trunk diseases of grapevine, are responsible for significant losses by causing premature decline and dieback in vineyards worldwide. The Portuguese Dão wine region is no exception. Local winegrowers’ knowledge on Grapevine Trunk Diseases (GTD) in general and of esca and Petri disease in particular is incomplete. The real scope of those problems has been based largely on individual perceptions rather than on a methodical evaluation of the situation. In order to get a full picture of the diseases impact, a leaflet with color pictures was produced and issued to winegrowers, accompanied by a simple questionnaire. The results of this survey represent a first indication of the extent of grapevine trunk diseases in the Dão wine region, specifically its economic impact and relevance to the local wine industry. In conjunction with the survey, several samples of wood collected from esca and Petri disease symptomatic vines, identified during the survey throughout the entire region, were processed and a collection of isolates of Phaeomoniella chlamydospora obtained. To determine the intra-specific variability among these isolates, morphological, cultural and molecular characteristics were evaluated. A protocol to study the pathogenicity with P. chlamydospora was conducted, consisting on the inoculation of cv. Touriga Nacional’s spurs with a previously studied P. chlamydospora isolate
Virulence and cross-infection potential of Ilyonectria spp. to grapevine
Black foot is an important disease of grapevines, affecting vines in nurseries as well as in young plantations. In recent years the disease has increased in incidence and severity throughout the world. Black foot is associated with at least two Campylocarpon and 12 Ilyonectria species, most of which have only recently been described. The recognition of previously unknown species, together with published reports of variability in virulence between and within species identified as I. macrodidyma and I. liriodendri, underlined the need to compare the virulence of isolates from these complexes. A further objective of this work was to determine the cross-infection potential of isolates of these species from other hosts to grapevine. Results from this study revealed recently described species such as I. lusitanica, I. estremocensis and I. europaea to be more virulent to grapevine than the species previously accepted as the main causal agents of black foot, such as I. liriodendri and I. macrodidyma. Furthermore, these results also provided support for isolates obtained from non-grapevine hosts to be as virulent to grapevines as isolates obtained from grapevine, underlying the cross-infection potential of these pathogens
