Paulo Duarte contra a correnteza: da pedra fundamental à origem vazia
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão, Programa de Pós-Graduação em Literatura, Florianópolis, 2013.Esta Tese de Doutorado versa sobre os contatos intelectuais estabelecidos por Paulo Duarte durante o período de seus dois exílios, que lhe foram impostos por Getúlio Vargas em 1934 e, depois de um período de retorno ao Brasil, entre 1938 e 1945, durante a vigência do Estado Novo. O texto se serve da imagem do rio, fundamental que foi ao longo dos escritos de Duarte, para realizar um movimento a contrapelo, ou seja, na contramão da correnteza, no sentido de encontrar as relações e contatos que não foram explorados na criação da imagem ?institucional? do escritor. Após um excurso em que se apresenta a imagem do rio e questões relativas à redação da autobiografia e às teorias da memória e da história que guiam as reflexões da Tese, debatem-se três problemas-chave em que a posição de Duarte permite ler diferentes teorias da modernidade na América Latina. Primeiramente, a ideia de patrimônio e o debate travado na passagem pela Argentina, em sua proximidade com as reflexões contemporâneas de Benjamin e com o pensamento dos Annales a respeito da História. Em seguida, a procura pelo fundamento da História e da cultura leva, pois, a pensar o problema da origem do humano, radicada em sua reflexão, na linguagem. Por fim, chega-se à emergência da problemática da imagem, a qual, em convergência com a origem e a linguagem, leva, na leitura e no contato de Duarte com Luis Buñuel, Anton Giulio Bragaglia e Samuel Beckett, ao torvelinho de radicar a origem no vazio. Abstract : This dissertation is about the intellectual contacts made by Paulo Duarte during his two exiles. The Brazilian president, Getúlio Vargas, exhiled Duarte for two times: in 1934 and, after a period back in Brazil, again, between 1938 and 1945, during the dictatorial government called Estado Novo. The text uses the image of the river, essential in Duarte's writings, to make a movement brushing the history against the grain, that is, against the stream, searching for the relations and contacts which have not been explored in the creation of the writer's "institutional" image. After an excursus in which the river's image is presented, as well as questions about autobiography and the theories about memory and history that guides the doctoral dissertation, we discuss three problems in which Duarte's position allows reading different modernity theories in Latin America. First come the idea of heritage and the debate in which he takes part during his passage through Argentina, in its proximity with Walter Benjamin and the Annales' reflections about History. Second, the search for History and culture's foundings takes Duarte's reflections to the problem of the mankind's origin, that is rooted in the language, according to Duarte. At last, the dissertation approaches the emergency of the problem of image, which, converging with the discussion about origin and language, takes, in the reading of and the contact between Duarte and Luis Buñuel, Anton Giulio Bragaglia and Samuel Beckett, to the swirl of rooting the origin in the void

No full textBothynus araya Duarte & Grossi, new species (Figs. 5 A–F; 7B; 8E; 9E; 10D, F; 12E) Diagnosis. Both sexes of B. araya are similar to B. entellus; however B. araya can be distinguished using the following characters: stridulatory apparatus with well-marked carinae near to basal margin in both sexes (Fig. 7B); parameres with lateral “flaps” distinctly as narrow as basal half (Fig. 8E); female differ from the females of other species in this group by the pronotum with weakly punctate concavity and smooth discal area (Fig. 10D) and proventrite with a long furrow at anterolateral angles (Fig. 10F). Etymology. The specific epithet is named as tribute to the grandmother of the first author. The name “araya” originates from the Tupi-Guarani dialect, meaning “grandmother”. This name should be treated as a noun in apposition. Type material. Holotype not dissected. Brasil: Paraná: Guarapuava, 3.IV.2012, Oliveira. G.B. – 1♂ (CERPE). Paratypes [16 males and 2 females].

Device-independent witness for the nonobjectivity of quantum dynamics
No full textQuantum Darwinism offers an explanation for the emergence of classical objective features (those we are used to at macroscopic scales) from quantum properties at the microscopic level. The interaction of a quantum system with its surroundings redundantly proliferates information to many parts of the environment, turning it accessible and objective to different observers. However, given that one cannot probe the quantum system directly, only its environment, how to determine whether an unknown quantum property can be deemed objective? Here we propose a probabilistic framework to analyze this question and show that objectivity implies a Bell-like inequality. Among several other results, we show quantum violations of this inequality, a device-independent proof of the nonobjectivity of quantum correlations. We also implement a photonic experiment where the temporal degree of freedom of photons is the quantum system of interest, while their polarization acts as the environment. Employing a fully black-box approach, we achieve the violation of a Bell-like inequality, thus certifying the nonobjectivity of the underlying quantum dynamics in a fully device-independent framework

Etymology The specific epithet ‘ endroedii ’ is a homage to Dr Sebö Endrödi, author of the genus Gibboryctes and one of the greatest experts on Dynastinae in the twentieth century. Geographic distribution (Figure 14 (b)) Brazil (Minas Gerais, Rio de Janeiro). Remarks Gibboryctes endroedii sp. nov. resembles G. szelenyii in the reddish-brown body colour and elytral interstriae densely covered with punctures mixed among small and shallow, and large and deep. Besides this, males of G. endroedii have variations in the shape of parameres that sometimes overlap those observed in G. szelenyii. However, G. endroedii sp. nov. is clearly distinct by the labrum parabolic in shape; maxillary galea rounded at apex with all teeth located subapically on the inner margin; anterior corners of pronotum covered with large and coalescent punctures. Gibboryctes szelenyii have triangular labrum; triangular maxillary galea with all teeth located at middle of inner margin; anterior corners of pronotum with contiguous punctures or spaced about 1 diameter of punctures.

Gibboryctes szelenyii Endrödi Notes on natural history of Gibboryctes Specimes of Gibboryctes szelenyii and G. endroedii sp. nov. were collected inside of epigeous termite nests (Blattodea:Isoptera: Termitidae). Gibboryctes szelenyii was found to be associated with many termite species (see remarks under G. szelenyii). Termites were not collected from the nests where specimens of G. endroedii were found. The localities of nests are marked by shrub vegetation and rocky outcrops characteristic of open areas of savannah and rupestrian grasslands (Figure 15 (a,b)). Adults, pupae and larvae of G. szelenyii and G. endroedii sp. nov. were found occupying the central portion of nests (Figure 16 (a–d)). When handled, the larvae emitted a stridulation sound produced by friction among the mandibles and maxillae. Furthermore, the larvae were observed building rigid galleries structured with faeces and saliva.The pupal chamber is also quite rigid,perhaps to avoid termite attacks (Figure 16 (c)).The larval excrement, when dried, acquires a peculiar aspect similar to ‘pellets’, flattened and subrectangular, with almost straight corners (90-degree angles),and which can be considered a diagnostic character for generic identification. This discovery represents the first record of an Oryctini associated with a termite nest.

Scopogonalia amazonensis Leal & Creao-Duarte 2016, sp. nov.
No full textScopogonalia amazonensis Leal & Creão-Duarte sp. nov. Diagnosis Green sharpshooters, crown and anterior third of pronotum yellow; aedeagus with two small semi-fused dentiform processes on ventral portion: one subapical and one apical, and pair of wing-shaped processes on dorsoapical portion. Comment The presence of the subapical dentiform process is a homoplastic autapomorphy of S. amazonensis sp. nov. shared with S. subolivacea, S. osteiphera sp. nov. and S. oglobini, whereas the pair of wing-shaped processes of the aedeagus is a homoplastic autapomorphy of S. amazonensis sp. nov. shared with S. subolivacea (Leal 2014). Type locality. Itacoatiara, Amazonas state, Brazil. Length. Male holotype, 5.7 mm. Male paratypes, 5.0– 5.9 mm; female paratypes, 6.0 mm. External morphology Head (Figure 6A) moderately produced anteriorly, median length of crown approximately 1/2 interocular width and 1/3 transocular width; anterior margin narrowly rounded in dorsal view; ocelli located behind anterior eye angles, each closer to adjacent anterior eye angle than to median line of crown, situated at pair of slight concavities. Pronotum (Figure 6A) with width approximately equal to transocular width; lateral margins convergent anteriorly; dorsopleural carinae incomplete, not attaining eyes, oblique. Fore wings (Figure 6A) opaque, membrane including all of apical cells, extending anteriorly along costal margin as far as basal half of wing. Hind legs with length of first tarsomere greater than combined length of two more distal ones. Coloration Background colour of crown, anterior third of pronotum, and mesonotum greenish-yellow, remainder of dorsum green (Figure 6A). Crown with round green maculae on and around ocelli (Figure 6A). Ventral region of body yellow; tergum of abdomen dark brown to black. Male genitalia Pygofer (Figure 6B), in lateral view, moderately produced posteriorly; dorsal margin slightly concave; posterodorsal margin broadly convex; apex acute; process arising from ventral margin and extending posterodorsally as far as apex of pygofer. Subgenital plates (Figure 6C) not extending posteriorly as far as apex of pygofer, gradually tapered towards apex; macrosetae uniseriate along outer margins. Styles (Figure 6D) slender, without preapical lobe, strongly curved. Connective (Figure 6D) Y-shaped. Aedeagus (Figure 6E), in lateral view, directed posterodorsally, with two tiny semi-fused dentiform processes on ventral portion, larger subapical one and smaller apical one, and pair of wing-shaped processes on dorsoapical portion (Figure 6E–F). Paraphyses (Figure 6E) paired, extending below aedeagus, with rami curved dorsally, not attaining aedeagus. Female genitalia Abdominal sternite VII (Figure 6G) longer than wide, lateral margins parallel, tapering near apex; posterior margin with concavity. Valvulae II (Figure 6H) expanded beyond basal curvature and gradually tapered towards acute apex; dorsal margin approximately rectilinear and parallel to ventral margin; preapical prominence distinct; teeth of basal and median portions inclined trapezoid (Figure 11H), becoming triangular towards apex (Figure 11I); first ones with flat posterior area, which becomes gradually smaller towards apex, where it is absent; denticles on all teeth and on apical portion; ventral dentate apical portion greater than dorsal one (Figure 11J). Etymology The species epithet, amazonensis, refers to the Amazon region, where the specimens were found. Type material Holotype: male, ‘Brasil-AM [Amazonas state]/ Itacoatiara \ Madeireira MIL, 024510S \583911W, 29–30.xi.2005 \ Luminosa móvel, J. A.\ Rafael, R. J. Machado &\ A. Silva Filho leg.’ (INPA). Paratypes: three males (INPA) with the same data as holotype; one male and two females: ‘ Rio Branco-AC [Acre state]\ 12-Jan-2004 \ Albuquerque, E.S.’ (DZUP). Comment Apparently, Young (1977, fig. 435) based on specimens of S. amazonensis his interpretation of S. subolivacea from Chanchamayo, Peru. The paratypes from Acre state have the pronotum almost completely yellow, with the posterior part light green. The fore wings also present a less intense tonality of green than the specimens from Amazonas do. However, the comparison of the male genitalia of specimens from both states support the hypothesis that they belong to the same species. Comparative notes This species resembles S. subolivacea, but differs from the latter by the small and semifused dentiform processes of the ventral aedeagal portion (Figure 6E) and by the narrower wing-shaped lateral processes (Figure 6E–F). The rami of the paraphyses are also longer in the new species than in S. subolivacea (Figure 6E).Published as part of Leal, Afonso Henrique, Creão-Duarte, Antonio José & Mejdalani, Gabriel, 2016, Taxonomic review of Scopogonalia Young, 1977 (Insecta: Hemiptera: Cicadellidae: Cicadellini) with description of six new species, pp. 1513-1542 in Journal of Natural History (J.

Computing the Largest Bond of a Graph
No full textA bond of a graph G is an inclusion-wise minimal disconnecting set of G, i.e., bonds are cut-sets that determine cuts [S,V\S] of G such that G[S] and G[V\S] are both connected. Given s,t in V(G), an st-bond of G is a bond whose removal disconnects s and t. Contrasting with the large number of studies related to maximum cuts, there are very few results regarding the largest bond of general graphs. In this paper, we aim to reduce this gap on the complexity of computing the largest bond and the largest st-bond of a graph. Although cuts and bonds are similar, we remark that computing the largest bond of a graph tends to be harder than computing its maximum cut. We show that Largest Bond remains NP-hard even for planar bipartite graphs, and it does not admit a constant-factor approximation algorithm, unless P = NP. We also show that Largest Bond and Largest st-Bond on graphs of clique-width w cannot be solved in time f(w) x n^{o(w)} unless the Exponential Time Hypothesis fails, but they can be solved in time f(w) x n^{O(w)}. In addition, we show that both problems are fixed-parameter tractable when parameterized by the size of the solution, but they do not admit polynomial kernels unless NP subseteq coNP/poly

Levantamento e caracterização de poços subterrâneos na zona urbana do município de Rafael Fernandes-RN
No full textSince 2012, the northeastern region of the country has been experiencing a considerable period
of drought. During this period, the region in which the municipality is located has been affected
by the scarcity of water. Thus, one of the alternatives that may have been used by the population
in order to mitigate the consequences of drought is the excavation of underground wells destined for the abstraction of groundwater. The present work aimed to perform a survey and characterization of the wells destined to the abstraction of groundwater, being these located in the urban zone of the city of Rafael Fernandes - RN. For collection of data, an exploratory and descriptive research was carried out, aiming to carry out a survey and characterization of the wells found in the urban area of the municipality, and this characterization sought to collect information on physical characteristics (depth of well digging, flow, among others), of consumption and environmental presented by each well, and also sought to acquire some knowledge about how the municipality's city water resources management is carried out. It was observed from the application of the research methods that 93.75% of the wells located in the
urban area of the municipality are deep tubular wells, while only 6.25% are wells called shallows, in the cases analyzed amazon wells, besides it has been found that some of the wells have a deficiency when related to the presence of certain elements that become essential to the well, such as protection covers, protective slab, filter, among others. With regard to the management of groundwater resources in the city, a deficit related mainly to the monitoring of the potability of the water consumed by the population is observed. This way, a deficiency related to the requirements expressed by the legislation in force when related to the project and execution of the analyzed wells is verified, especially when analyzing Questions aimed at guaranteeing the quality of these waters.Desde 2012 a região nordeste do país vem passando por um considerável período de estiagem, durante esse período a região na qual se localiza o município em estudo vem sofrendo com as

RN. Para coletas de dados foi realizado uma pesquisa exploratória e descritiva, visando assim
realizar um levantamento e caracterização dos poços encontrados na zona urbana do município,
sendo que tal caracterização buscou o levantamento de informações quanto a características
físicas (profundidade de escavação dos poços, valores de vazão, entre outros), de consumo e
ambientais apresentada por cada poço, além do mais buscou-se adquirir certo conhecimento
sobre como é realizada a gestão dos recursos hidricos da cidade por parte da prefeitura municípal. Observou-se a partir da aplicação dos metodos de pesquisa que 93,75% dos poços localizados na zona urbana do municipio são poços tubulares profundos, enquanto que somente 6,25% são poços denominados rasos, nos casos analisados poços amazonas, além do mais verificou-se que alguns dos poços apresentam uma deficiência quando relacionados a presença de determinados elementos que se tornam essenciais ao poço, tais como tampas de proteção, laje de proteção, filtro, entre outros. Com relação a gestão dos recursos hídricos subterrâneos na cidade, observa-se um déficit relacionado principalmente a vigilância sobre a qualidade da potabilidade da água consumida pela população. Desta forma, percebe-se uma deficiência relacionada aos requisitos expressos pela legislação vigente quando estes relacionados ao projeto e execução dos poços analisados, principalmente quando se analisa questões voltadas a garantia da qualidade destas águas.Trabalho não financiado por agência de fomento, ou autofinanciad
Sources of Competitiveness in Tourist Local Systems
No full textAt the end of the XIX Century, Marshall described the existence of some concentrations of small and medium enterprises specialised in a specific production activity in certain districts of some industrial English cities. Starting from his contribute, Italian scholars have paid particular attention to this local system of production coined by Marshall under the term industrial district. In other countries, different but related territorial models have played a central role as the milieu or the geographical industrial clusters. Recently, these models have been extended to non-industrial fields like culture, rural activities and tourism. In this text, we explore the extension of these territorial models to the study of tourist activities in Italy, using a framework that can be easily applied to other countries or regions. The paper is divided in five sections. In the first one, we propose a review of the territorial models applied to tourism industry. In the second part, we construct a tourist filiere and we apply a methodology for the identification of local systems through GIS tools. Thus, taxonomy of the Italian Tourist Local Systems is presented. In the third part, we discuss about the sources of competitiveness of these Tourist Local Systems. In the forth section, we test a spatial econometrics model regarding different kinds of Italian Tourist Local Systems (rural systems, arts cities, tourist districts) in order to measure external economies and territorial networks. Finally, conclusions and policy implications are exposed.Tourism and travel industry, industrial districts theory, regional and local development, external economies, spatial econometrics.
