Paepalanthus leucocephalus Ruhland, M. J. G. Andrade 1903
No full text3. Paepalanthus leucocephalus Ruhland in Engler, Pflanzenr. IV.30 (Heft 13): 200. 1903. Lectotype, first-step (designated by Moldenke 1975): at B. Lectotype, second-step (here designated): BRAZIL. Minas Gerais: Serra dos Cristaes, 4 April 1892, C.A.W. Schwacke 8503 (B [10_0243944]!, isolectotypes B [10_0243943]!, K [000640071]!). (Figures 2A–B, 3, 4N –P, 6A–H) Ruhland (1903) described Paepalanthus leucocephalus based on the collection Schwacke 8503, gathered in Minas Gerais. We found three specimens related to this collection, two deposited at B, where Willy Ruhland mostly worked, and one housed at K. It is also a situation with no holotype being clearly indicated, requiring a lectotype selection (McNeill 2014, Turland et al. 2018). Moldenke (1975) indicated that the type of this species is deposited at B with the indication “ Thelxinoë leucocephala ”. The two specimens at B contain the same annotation, therefore we consider Moldenke’s (1975) statement as a first-step lectotype indication according to the article 9.17 of the ICN (Turland et al. 2018). One of the specimens housed at B contains Ruhland’s original handwritings and drawings attached, also perfectly matching the description. We designate this specimen [B barcode 10_0243944] as the second-step lectotype. Paepalanthus leucocephalus is sister of P. scleranthus and they are the only species in Paepalanthus subg. Thelxinoë according to Ruhland (1903). They also share the annual caulescent habit of small plants, with the absence of scapes and spathes, capitulum sessile, involucral bracts not differentiated from the apical leaves, floral bracts acuminate, and dimerous flowers. They are sympatric in the Espinhaço Range in some mountains in Minas Gerais, and also in Rio de Contas, Bahia. There is also a population occurring in sandy soils further north in Morro do Chapéu in Bahia (Figure 3). P. leucocephalus is morphologically similar to P. scleranthus (Figures 6 I-N), sharing also the loss of the nectariferous branches (Silva et al. 2016), a condition observed in P. paganuccii and P. sessiliflorus as well (Figures 4–5). The whitish capitula are a visible character to distinguish P. leucocephalus from P. scleranthus, along with the convex leaves clearly distinguished into sheath and blade, and the morphology of the flowers, illustrated for the first time in this paper. However, the segregation of these species is weak and deserve further investigations as previously stated by Moldenke “The species is extremely close to P. scleranthus and I am not at all certain that the two are distinct” (Moldenke 1975). As expected of a widespread species, Paepalanthus leucocephalus encompasses a relevant morphological variation and the relationship with P. scleranthus is complex (Figures 2, 4, 6). Some populations, as the one represented by the specimen Andrade 625 from Rio de Contas in Bahia, are composed of individuals noteworthy for being smaller than specimens from other populations, especially from those occurring in the Southern Espinhaço Range. The populations from Minas Gerais, occurring mostly in the Diamantina Plateau, also have more hairy floral structures and a shinier white capitulum. The inclusion of specimens from the whole morphological and geographical range of P. leucocephalus and P. scleranthus in future studies at the population level is crucial to circumscribe these species more accurately.

Rastros freudianos em Mário de Andrade
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão. Programa de Pós-Graduação em Literatura.A presente tese aborda as relações entre Mário de Andrade # leitor de Freud # e a psicanálise, ou seja, o uso feito pelo escritor de conceitos e noções psicanalíticas. Ao incorporar a psicanálise aos seus estudos sobre o folclore, Mário lança mão dos termos psicanalíticos recalcamento e sublimação, criando uma tradução própria que recobre, aproximadamente, a extensão de tais noções: seqüestro. Além deste termo, outros três são destacados da obra de Mário de Andrade como termos psicanalíticos e/ou articuláveis com a psicanálise: libido, loucura e inconsciente. Percorrendo as vias freudiana e lacaniana dos conceitos, destacamos trechos da obra do escritor nos quais surgem os temas em questão. A tese desenvolve-se em duas direções: por um lado, busca a psicanálise lida e interpretada por Mário de Andrade, e por outro, através da psicanálise, num exercício crítico, constrói leituras possíveis para alguns dos seus textos. Este percurso psicanalítico por textos do escritor perfaz o que chamamos de rastros freudianos em Mário de Andrade
Evidence for the decay B0→J/ψω and measurement of the relative branching fractions of meson decays to J/ψη and J/ψη′
No full textFirst evidence of the B 0 → J / ψ ω decay is found and the B s 0 → J / ψ η and B s 0 → J / ψ η ′ decays are studied using a dataset corresponding to an integrated luminosity of 1.0 fb -1 collected by the LHCb experiment in proton-proton collisions at a centre-of-mass energy of sqrt(s) = 7 TeV. The branching fractions of these decays are measured relative to that of the B 0 → J / ψ ρ 0 decay:frac(B (B 0 → J / ψ ω), B (B 0 → J / ψ ρ 0)) = 0.89 ± 0.19 (stat) - 0.13 + 0.07 (syst),frac(B (B s 0 → J / ψ η), B (B 0 → J / ψ ρ 0)) = 14.0 ± 1.2 (stat) - 1.5 + 1.1 (syst) - 1.0 + 1.1 (frac(f d, f s)),frac(B (B s 0 → J / ψ η ′), B (B 0 → J / ψ ρ 0)) = 12.7 ± 1.1 (stat) - 1.3 + 0.5 (syst) - 0.9 + 1.0 (frac(f d, f s)), where the last uncertainty is due to the knowledge of f d / f s, the ratio of b-quark hadronization factors that accounts for the different production rate of B 0 and B s 0 mesons. The ratio of the branching fractions of B s 0 → J / ψ η ′ and B s 0 → J / ψ η decays is measured to befrac(B (B s 0 → J / ψ η ′), B (B s 0 → J / ψ η)) = 0.90 ± 0.09 (stat) - 0.02 + 0.06 (syst)
A 2 h periodic variation in the low-mass X-ray binary Ser X-1
No full textSpectroscopy of the low-mass X-ray binary Ser X-1 using the Gran Telescopio Canarias have revealed a ?2 h periodic variability that is present in the three strongest emission lines. We tentatively interpret this variability as due to orbital motion, making it the first indication of the orbital period of Ser X-1. Together with the fact that the emission lines are remarkably narrow, but still resolved, we show that a main-sequence K dwarf together with a canonical 1.4 M? neutron star gives a good description of the system. In this scenario, the most likely place for the emission lines to arise is the accretion disc, instead of a localized region in the binary (such as the irradiated surface or the stream-impact point), and their narrowness is due instead to the low inclination (?10°) of Ser X-1
Measurement of the ratio of prompt χ c to J / ψ production in pp collisions at √s = 7 TeV
No full textThe prompt production of charmonium χ c and J / ψ states is studied in proton-proton collisions at a centre-of-mass energy of √s = 7 TeV at the Large Hadron Collider. The χ c and J / ψ mesons are identified through their decays χ c → J / ψ γ and J / ψ → μ + μ - using 36 pb - 1 of data collected by the LHCb detector in 2010. The ratio of the prompt production cross-sections for χ c and J / ψ, σ (χ c → J / ψ γ) / σ (J / ψ), is determined as a function of the J / ψ transverse momentum in the range 2 < p T J / ψ < 15 GeV / c. The results are in excellent agreement with next-to-leading order non-relativistic expectations and show a significant discrepancy compared with the colour singlet model prediction at leading order, especially in the low p T J / ψ region
Considerações sobre a construção intelectual de Mário de Andrade: o Turista aprendiz
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão. Programa de Pós-graduação de LiteraturaEsta dissertação investiga a posição do intelectual Mário de Andrade, ao se referir à obra O turista aprendiz, no que concerne a sua representação e a seu desempenho como escritor voltado a compreender os problemas sociais, durante sua estada nos estados do Norte e do Nordeste brasileiro. O bojo das visitas etnográficas embutido na obra é sua atenção ao público proletário, na busca pela formulação de uma cultura popular nacional. O escritor modernista assume postura de intelectual comprometido com a sociedade que ele busca representar, em seus escritos e crônicas de viagens dessa mesma obra. Buscamos ensaiar, exclusivamente, sua atuação durante suas andanças nas principais cidades do Norte e Nordeste Brasileiro, com a preocupação de integrar a seus escritos um caráter social. Também abrimos uma investigação sobre as principais vanguardas europeias, assim como sobre as facetas intelectuais de Mário de Andrade, a fim de rastrear seu potencial de artista polígrafo, perfazendo seu movimento nos diversos meios artísticos durante sua vida. As vanguardas europeias oriundas de Mário de Andrade são fruto de grande relevância social e literária inserida em seus contextos de época, onde agem como desencadeadoras e antecipadoras de outras obras de grande valor. Com rigor, problematizamos todo esse material artístico, buscando possíveis respostas para seu estilo eclético, frente às responsabilidades que ele assumiu como intelectual múltiplo, defendendo o povo e da cultura brasileira. Mário de Andrade, ao se aproximar do povo, gerou inúmeras contribuições sociais. Por esse motivo, utilizamos muitos fragmentos extraídos da própria obra, para evidenciar nosso mote de pesquisa, sob a luz dos teóricos que dão consistência ao objeto de análise. Diante dos fragmentos iluminados, buscamos: levantar interpretações, esmiuçando-os, para buscar elementos que esbocem as relações abrangentes, sob a luz do cabedal teórico justificado e escolhido; e trazer o pensamento de Mário de Andrade, como representação canônica de um modelo literário. Fechamos o trabalho com o levantamento de um debate imaginário com o escritor Mário de Andrade, fazendo com que ele especule suas principais respostas e busque, ainda mais, indagar alguns assuntos pertinentes ao oficio do escritor e do intelectualThis dissertation aims at investigating the perspective of the intellectual Mario de Andrade in his work O turista aprendiz, in relation to his representation and performance as a writer who is concerned with comprehending the social problems he witnessed during his stay in the North and in the Northeast Brazil. The core of his ethnographic visits, embedded in his work, is the attention devoted to the proletariat audience, in the search for the formulations of a popular culture, aimed at a national level. We understand that the modernist writer assumes the position of an intellectual committed to the society he aims at representing through his writings and the travel chronicles present in the aforementioned work. We shall discuss, exclusively, his performance in his trips around the main cities of North and Northeast Brazil, with the concern of integrating a type of social character to his writings. This work also opens a discussion about the main European avant-gardes, as well as intellectual aspects of Mario de Andrade, attempting to trace his potential as a polygraph artist, comprising his movement in the various artistic means during the trajectory of his life. The European avant-gardes derived from Mario de Andrade are results of a great social and literary relevance inserted in his time contexts, in which they act as triggers and anticipators of other works of great value. Accurately, we problematize all this artistic material, searching for possible answers for his eclectic style facing the responsibilities he assumed as a multiple intellectual who defends the people and the culture of Brazil. When approaching the people, Mário de Andrade produced social contributions that permeate all this dissertation. For this reason, we use many fragments extracted from de Andrade's work to highlight our research motto, under the light of the theorists who will give consistence to our analysis object. Facing the enlighted fragments, we will try to raise some interpretations, in detail, scrutinizing them in order to examine and search for elements that can outline the broad relations under the light of the justified and chosen theoretical parameters. Furthermore, we bring Mário de Andrade#'s thoughts as a canonic representation of a literary model. Finally, we will examine and end our work with and imaginary debate with the writer Mário de Andrade, making him speculate his main answers and look for more questioning of some subjects concerning the work of the writer and of the intellectua
Políticas do primitivo: as estéticas modernistas de Mario de Andrade e Lezama Lima
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e ExpressãoEste trabalho visa, fundamentalmente, interpretar as tensões entre as estéticas de Mário de Andrade e de Lezama Lima na medida em que elas instauram discursividades alternativas que situadas no confronto primitivo/moderno, configuram identidades culturais diferenciadas. Enquanto problema da modernidade, a presença do primitivo coloca em crise a identidade cultural do Ocidente ao provocar o surgimento do Outro, vale dizer, a irrupção da diferença no âmbito do Mesmo. Neutralizada na abstração conceitual de "primitivismo", essa diferença é incorporada à identidade ocidental, ora a partir de concepções evolucionistas, ora a partir de operações dialéticas. Numa tentativa de interferir nesse processo incorporativo, postulamos a ressemantização do conceito de primitivo, com o propósito de recuperá-lo enquanto elemento perturbador dos efeitos padronizadores da modernidade. Nesse sentido, os primitivos latinos-americanos podem ser pensados como formas de apropriação trangressivas que, entre outras coisas, quebram com uma lógica causalista, fragmentam a linearidade das perspectivas evolucionárias e reelaboram, assim, estagnadas tradições estéticas e históricas. Consideramos, portanto, que as estéticas de Mário de Andrade e de Lezama Lima, inseridas nos conflitos de uma modernidade periférica, que se contrapõe aos efeitos globalizadores da racionalidade moderna
