Peristome well developed laterally, forming a median U-shaped pseudosinus (Fig. 7B). Primary orifice circular and hidden by peristome, with a broad anvil-shaped lyrula, occupying almost the entire proximal margin of the orifice and with a straight edge; six oral spines (rarely five) on non-ovicellate zooids and only two spines visible when ovicell is present (Fig. 7A, B); spine bases robust [24–27– 31 µm in diameter (SD 2, N 17)]. Single or paired oval, latero-oral avicularia [L 43–48– 61 µm (SD 5, N 14)] with rostrum tip serrated, directed distolaterally towards the orifice, with complete crossbar (Fig. 7 B, D).

Reverter-Gil & Fernández-Pulpeiro (2007), who studied the paratypes of <i>P. talismani</i> and images of <i>P. fraseli</i>, mentioned that the two species share several characters, such as the broad lyrula with straight edge, well developed peristome, avicularium supported by peristome and up to five oral spines. These authors recommended a taxonomic revision to confirm the identification and distribution of these two species. Some of these characters are also shared with <i>P. amazonensis</i> Ramalho & Moraes <b>n. sp</b>. (i.e., broad lyrula, ovicell perforated by circular, tubular pseudopores, and avicularia lateral to the orifice), but <i>P. fraseri</i> differs in having 3–5 oral spines, a single long-pointed frontal avicularium (absent in the new species), and peristomial avicularia with smooth, rounded to elliptical rostrum (serrated in the new species), while <i>P. talismani</i> differs in having 4–5 oral spines, ovicell almost immersed in the distal zooid, and lateral and frontal avicularia similar in size (lateral avicularia are smaller than frontal ones in the new species). Another similar species is <i>P. tubula</i> (Kirkpatrick, 1888) described from Mauritania, which has six oral spines, broad lyrula, very small frontal avicularium, lacks avicularia lateral to orifice, and the peristome is not as well developed as in the new species.</p>Published as part of <i>Ramalho, Laís V., Moraes, Fernando C., Salgado, Leonardo T., Bastos, Alex C. & Moura, Rodrigo L., 2021, Bryozoa from the reefs off the Amazon River mouth: checklist, thirteen new species, and notes on their ecology and distribution, pp. 1-45 in Zootaxa 4950 (1)</i> on pages 14-16, DOI: 10.11646/zootaxa.4950.1.1, <a href="http://zenodo.org/record/4643245">http://zenodo.org/record/4643245</a>
The astrochemical observatory: Computational and theoretical focus on molecular chirality changing torsions around O – O and S – S bonds
No full textThe observation of hydrogen peroxide in the interstellar medium represents a remarkable discovery for the astrochemistry community. The prototypical role that this molecule, arguably the simplest chiral molecule, plays in the evolution of life in biospheres, is related to the chirality change transitions associated with the torsional motions around the O - O and the S - S bonds. In this paper, we present an overview on the state-of-art of possible experiments to demonstrate chiral effects discrimination and computational tools applied to peroxides and persulfides
Stephanollona domuspusilla Ramalho & Moraes & Salgado & Bastos & Moura 2021, n. sp.
No full textStephanollona domuspusilla Ramalho & Moraes n. sp. (Figs 11D, E; 12A, B) Material examined. Holotype: MNRJBRY-1543: Brazil, Amapá state (Sta #3, 03°35.4267’N – 049°07.6028’W), 90 m, on sponge, 26 September 2014, collected by Fernando Moraes & Rodrigo Moura (NHo Cruzeiro do Sul). Etymology. From the Latin noun domus (meaning home) plus the adjective pusilla, - us, - um (meaning small), referring to the small size of the zooids. Diagnosis. Autozooids with tubercular, imperforate frontal shield; 5–7 oral spines, the most proximal pair lanceolate; orifice with distal border denticulate and U-shaped sinus constricted by small lateral teeth; condyles projecting beyond the sinus border. Two kinds of adventitious avicularia: small, single and rounded suboral avicularium with serrated rostrum, and another large, elongate avicularium, triangular with rounded tip, placed laterally. Description. Colony encrusting, multiserial, uni- to multilaminar (Fig. 11D). Autozooids small, oval to irregularly polygonal, longer than wide [L 317–369–441 (SD 35, N 11); W 242–302– 360 µm (SD 42, N 11)]; frontal shield tubercular, imperforate except for some (5–7) scattered medium to large sized [14–24– 39 µm diameter (SD 6, N 27)], rounded, marginal areolar pores (Figs 11D, E, 12A, B). Orifice cleithridiate, longer than wide [L 116–133–147 (SD 10, N 11); W 101–111– 118 µm (SD 7, N 11)], with 5–7 (usually six) hollow spines [13–26– 35 µm diameter (SD 6, N 17)], four visible in ovicellate zooids; the most proximal pair of spines lanceolate, the others spear-shaped with irregular calcification (Figs 11E, 12A, B); distal border denticulate with 14–18 small beads; U-shaped sinus constricted by small lateral teeth; two long downward facing condyles projecting beyond the sinus border (Figs 11E, 12A, B); one zooid with a broader and shallower sinus observed (Fig. 11E). Two types of avicularia: (1) single, small [L 42–57– 73 µm (SD 10, N 7)], rounded avicularium placed suborally (rarely laterally) and oriented laterally, usually inclined in respect to the frontal wall; rostrum rounded, serrated, and crossbar complete without columella (Figs 11E, 12A, B); (2) single large, elongate [L 187–203– 219 µm (SD 16, N 3)], somewhat triangular avicularium, placed laterally to orifice; rostrum triangular with rounded and slightly hooked tip, slightly curved to one side; crossbar complete without columella (Figs 11E, 12A). Ovicell hyperstomial, wider than long [L 146–149–151 (SD 4, N 2); W 181–186– 191 µm (SD 7, N 2)], with smooth ooecial surface similar to the zooidal frontal wall (Fig. 12B). Remarks. The two most similar species recorded in Brazil are Stephanollona arborescens Vieira et al., 2010b and S. angusta Vieira et al., 2010b. The former species has the same small, rounded avicularium and six spines, but differs from S. domuspusilla Ramalho & Moraes n. sp. in having larger zooids (L 346–468–667, W 259–346– 445 µm), smaller orifice wider than long (L 80–94–111, W 93–103– 117 µm), condyles encroaching on the sinus (in the new species the condyles slightly surpass the opening), small avicularium usually proximo-laterally placed and proximo-laterally directed (in the new species the avicularium is suboral and laterally directed), and occasionally elongate avicularia rarely associated with the orifice (while in the new species it is lateral to orifice), and the rostrum is not hooked and the lateral margins are almost straight (see fig. 87, 89 in Vieira et al. 2010b). Stephanollona angusta has two or more avicularia per autozooid, small, rounded avicularium with smooth rostrum placed proximolaterally to the orifice or proximally to the large avicularia. Stephanollona boreopacifica Yang et al., 2018b from Korea, resembles the new species in having U-shaped sinus and rounded small avicularia with serrated borders, but can be distinguished by the narrower orifice (L 103–138, W 70–85 µm), and wider, more elongate avicularia associated with the ovicell (Yang et al. 2018b). Several species included in Stephanollona have broad, shallow orificial sinus, a feature characteristic of Stephanollina Vigneaux, 1949, previously a subgenus of Stephanollona, that Gordon (2006) suggested to elevate to the rank of genus in the new family Sfeniellidae Gordon, 2006. More recently, Di Martino & Taylor (2017) followed Gordon’s (2006) suggestions and included Stephanollina in Sfeniellidae modifying both the diagnoses of the family and of the genus Stephanollina, selecting Stephanollina dentata as the type species. Based on this, species of Stephanollona with shallow sinus must be reviewed.Published as part of Ramalho, Laís V., Moraes, Fernando C., Salgado, Leonardo T., Bastos, Alex C. & Moura, Rodrigo L., 2021, Bryozoa from the reefs off the Amazon River mouth: checklist, thirteen new species, and notes on their ecology and distribution, pp. 1-45 in Zootaxa 4950 (1) on pages 23-26, DOI: 10.11646/zootaxa.4950.1.1, http://zenodo.org/record/464324
Pourtalesella duoavicularia Ramalho & Moraes & Salgado & Bastos & Moura 2021, n. sp.
No full textPourtalesella duoavicularia Ramalho & Moraes n. sp. (Fig. 12C–F) Material examined. Holotype: MNRJBRY-1443; Paratype: MNRJBRY-1458: Brazil, Pará state (Sta #6, 00°45.359’N – 046°38.49’W), 50 m, both samples on rhodoliths, 29 September 2014, collected by Fernando Moraes & Rodrigo Moura (NHo Cruzeiro do Sul). Etymology. From the Latin duo (meaning two) plus avicularia, referring to the two types of avicularia characteristic of the species. Diagnosis. Colony encrusting, starting as a flat sheet and becoming irregular with age. Orifice subcircular with broadly V-shaped sinus. Two kinds of avicularia: small and rounded with serrated rostrum, placed distolaterally to the orifice; larger and triangular with smooth rostrum, placed below and laterally to the orifice. Ovicell globose, flat frontally; ectooecium partially calcified exposing a semicircular area of entooecium with radial ridges; not closed by zooidal operculum. Description. Colony encrusting, multiserial, initially flat with autozooids regularly disposed, but becoming irregular (huddle) with age, uni- or multilaminar (Fig. 10A, B). Autozooids rounded hexagonal, longer than wide [L 329–375–437 (SD 32, N 18); W 239–275– 323 µm (SD 23, N 18)], separated by deep furrows obscured with age (Fig. 12C, D). Frontal shield in young zooids smooth, with small, rounded pseudopores becoming smaller with increasing calcification. Primary orifice subcircular [L 80–90–102 (SD 7, N 18); W 82–92– 96 µm (SD 4, N 23)], anter smooth and poster with broadly V-shaped sinus; peristome surrounding the primary orifice proximally and laterally but not covering it (Fig. 12D). Two types of avicularia: (1) infrequent, small [L 40–49– 56 µm (SD 8, N 3)] avicularium placed distolaterally to orifice embedded in the peristome, oriented proximolaterally, sometimes slightly larger, on a large cystid and directed upwards; rostrum rounded with serrated edge and crossbar complete, (Fig. 12E); (2) more common, larger avicularium [L 73–91– 109 µm (SD 8, N 16)], placed laterally below the orifice, sometimes quite far from it, oriented distolaterally, sometimes raised from the frontal surface; rostrum triangular with smooth edge; crossbar complete (Fig. 10A–C). Ovicell globose, wider than long [L 128–146–164 (SD 12, N 11); W 156–176– 205 µm (SD 14, N 10)], usually immersed in calcification, flat frontally; ectooecium partially calcified exposing a semicircular area of entooecium with radial ridges (Fig. 12E, F); aperture not closed by zooidal operculum; usually peristome fused laterally with the proximal margin of the ovicell. Remarks. The main difference between Pourtalesella Winston, 2005 and Buffonellaria Canu & Bassler, 1927 is in the frontal shield, which is perforate in the former genus and imperforate in the latter (Berning & Kuklinski 2008). Despite these authors mentioned that some autozooids of Buffonellaria may occasionally retain pseudopores in later ontogeny, and this difference may have less systematic significance than previously thought, we prefer to maintain the Amazonas’ specimens in Pourtalesella, owing to the presence of a pseudoporous frontal shield, as seen in other Atlantic Pourtalesella species, pending a revision of this genus. Four Pourtalesella species have been described from the Atlantic Ocean, two of them from Brazil: P. alipioi (described as Schizopodrella alipioi Marcus, 1955), and P. carvalhoi (Marcus, 1937). Pourtalesella alipioi has ovicell with pseudoporous entooecium, two latero-oral avicularia with oval rostra, and four distal oral spines. In the original description of Pourtalesella, Winston (2005) mentioned “no spines except on ancestrula”, but the material described by Marcus (1955) has four oral spines and the ooecial surface perforated by several pores. Therefore, the status of S. alipioi requires clarification. On the other hand, P. carvalhoi is similar to P. duoavicularia Ramalho & Moraes n. sp. in the number and shape of avicularia, and shape of the ovicell, but can be distinguished by the sinus shape (very narrow V-shaped in P. carvalhoi, very broad in the new species), and the smaller oral avicularium. Pourtalesella incrassata (Canu & Bassler, 1928b), described from North Atlantic, differs from the new species in having narrower V-shaped sinus, single or paired oval avicularia placed laterally to the orifice and oriented distolaterally, and additional avicularia on or close to the ovicellate zooids (Winston 2005, fig. 253), while P. rugosa (Osburn, 1940), also described from North Atlantic, has only oral avicularia with blunt pointed rostra.Published as part of Ramalho, Laís V., Moraes, Fernando C., Salgado, Leonardo T., Bastos, Alex C. & Moura, Rodrigo L., 2021, Bryozoa from the reefs off the Amazon River mouth: checklist, thirteen new species, and notes on their ecology and distribution, pp. 1-45 in Zootaxa 4950 (1) on pages 26-27, DOI: 10.11646/zootaxa.4950.1.1, http://zenodo.org/record/464324

Fernando Henrique Cardoso e o pensamento político brasileiro
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Filosofia e Ciências Humanas, Programa de Pós-Graduação em Sociologia Política, Florianópolis, 2015.A construção do legado de Fernando Henrique Cardoso tem transcorrido a partir do signo de rupturas e dicotomias estruturantes, características que se articulam em torno da ideia da transição da atividade intelectual para a atividade política, num processo que reforça traços marcantes da imaginação política brasileira. Partindo da crítica dessa visão, este trabalho investiga o que o processo de formação do legado do autor como levado a cabo até aqui tem a dizer sobre os modos pelos quais se produz e se reinventa o ?pensamento político brasileiro?, ou, em outras palavras, o que sua trajetória intelectual individual representa em relação à trajetória coletiva de pensamento designada por esta expressão. Duas teses interpretativas principais são desenvolvidas ao longo deste trabalho: a primeira, de que o fio de continuidade e de unidade entre os diversos momentos da trajetória intelectual de Cardoso, negado pelas abordagens que até o presente vão dando conta da sistematização de seu legado, pode ser reconstruído e recuperado se a ênfase da análise recair na especificidade política de seus escritos, reconstrução e recuperação que, obviamente, não se furtam a considerar possíveis inconsistências, incoerências e mudanças nas crenças ao longo de sua trajetória; e a segunda, de que tal pensamento político, sem desconsiderar outras fontes genericamente rotuladas como ?universais?, estrutura-se a partir de um diálogo seletivo, sistemático e contínuo com algumas das principais matrizes de interpretação do político no país, diálogo este que, de um lado, torna possível evidenciar a existência de uma cosmovisão a atuar como ?fio condutor? para o conjunto de seu pensamento (conferindo a ele um sentido de coerência) e, de outro, entender o impacto ressignificador desse pensamento sobre tais matrizes. O trabalho está organizado em três partes: na primeira, produz-se uma reflexão teórico-metodológica do campo do pensamento político brasileiro; na segunda, discute-se a especificidade da reflexão política do autor a partir de dois momentos distintos (o do estabelecimento e o da consolidação das suas crenças políticas); e na terceira, num exercício de tentar aproximar as duas primeiras, discute-se a especificidade da inscrição do pensamento político do autor no campo do pensamento político brasileiro a partir de duas variáveis: as filiações e as recepções.Abstract : The construction of Fernando Henrique Cardoso?s legacy has been developed based on the mark of structuring ruptures and dichotomies, characteristics that are both articulated around the idea of the transition from the intellectual to the political activity, in a process that reinforces strong features of the Brazilian political imagination. Anchored in a criticism of this view, this study investigates what the process of formation of the author?s legacy developed until the present moment reveal about the forms through which the ?Brazilian political thought? is produced and reinvented, or, in other words, what his personal intellectual trajectory represents in relation to the collective thought trajectory designated by this expression. Two main interpretative theses are tested throughout this work: the first one is that the continuity and the unity between the several moments of Cardoso?s intellectual trajectory (denied by the approaches that, until the present moment, have been systematizing his legacy) can be reconstructed and recuperated if the emphasis of the analysis lies in the political specificity of his writings - assuming that both the reconstructing and the recuperation, obviously, do not fail to consider possible inconsistencies, incoherences and changes in the beliefs of the author throughout his trajectory; and second , that such political thought , without disregarding other sources generally labeled as ?universal? , is structured from a selective, systematic and continuous dialogue with some of the main forms of interpretation of the policy in the country, this dialogue , on the one hand , makes it possible to show the existence of a worldview to act as ?common thread? for all of his thought (giving him a sense of coherence), and on the other, to understand the impact of this ressignificador thinking about such matrices. The work is organized in three parts: in the first, the field of the Brazilian political thought is theoretical and methodologically questioned; in the second part, the specificity of the author?s political reflection is discussed based on two different moments (the establishment and the consolidation of his political beliefs); and, in the third part, in an attempt of approximating the two previous parts, the specificity of the insertion of the author?s political thought in the Brazilian political thought field is discussed, which is based on two variables: the filiations and the receptions

Autozooid with 16–20 costae, the first pair forming a bifid protuberance, and seven oral spines; interzooidal avicularia semi-erect, with acicular and serrated rostrum oriented distally or distolaterally; single or paired semi-erect avicularia associated with the type A ovicell ornamented with a median suture. Description. Colony encrusting, multiserial, unilaminar. Autozooids polygonal, longer than wide [L 258–352– 479 (SD 52, N 22); W 213–256– 307 µm (SD 25, N 22)] (Fig. 6A). Orifice transversally D-shaped, wider than long [L 34–49–64 (SD 5, N 21); W 52–59– 67 µm (SD 4, N 21)], with seven (non-ovicellate zooids) or four (ovicellate zooids) oral spines (Fig. 6A–C); the most proximal pair of spines only slightly above the proximal border of the orifice; base of the spines thick, surface irregularly calcified ending in a thin tip (Fig. 6B, C). Proximal and distal orifice edges smooth, without beaded margin or condyles (Fig. 6A, B). Frontal surface with 16–20 costae converging towards the median line and 5–7 intercostal lacunae; first pair of costae, when not developed, leaving an elliptical pore visible, but often more developed and raised, forming a bifid protuberance hiding the elliptical proximal pore (Fig. 6B, C). Interzooidal avicularia semi-erect [L 98–137– 180 µm (SD 22, N 25)], large, oriented distally or distolaterally, developed from one pore on the lateral wall; rostrum acicular with serrated margins, ending in a hooked tip; proximal region rounded with a large pore; blunt condyles (Figs 6A, B). One or two semi-erect avicularia associated with ovicell (Fig. 6A, C). Ovicell hyperstomial, type A (sensu Bishop & Househam 1987), wider than long [L 93–113–129 (SD 9, N 15); W 128–158– 176 µm (SD 13, N 10)], irregular in shape, occupying part of the next distal zooid, with smooth ooecial surface; a median suture extending from proximal border to mid region (Fig. 6A, C); aperture closed by zooidal operculum. Remarks. To date there are no Glabrilaria species described from Brazil (Vieira et al. 2008; Winston et al. 2014). Among Brazilian cribrilinids only Puellina octospinata Winston et al., 2014, here re-assigned to Cribrilaria, C. octospinata n. comb., following Rosso et al. (2018), has 7–8 oral spines but differs in having smaller and not semi-erect avicularia. The most similar species is Cribrilaria harmeri (Ristedt, 1985), from the Pacific Ocean, which has seven oral spines, four visible in fertile zooids, and a single subapertural lumen. However, it differs from the new species in having the first pair of costae proximal to the orifice forming a shorter umbo, a narrower interzooidal avicularium (not semi-erect) that can have either smooth or finely serrated margin (always serrated in the new species), smaller polymorphs (zooids, avicularia and ovicells) than the new species (see Dick et al. 2007; Dick & Grischenko 2017; Yang et al. 2018a), and an umbo near the proximal margin of the ovicell (not observed in the new species). Glabrilaria africana (Hayward & Cook, 1983) and G. corbula Bishop & Househam, 1987 also have seven oral spines, but the former species has a greater number of subapertural pores (up to five large and many small ones), no suboral umbo, and a small umbo on the ovicell, while the latter species has avicularia with smooth rostrum and ovicell ornamented by 4–6 ridges. From the North Atlantic, there are two Glabrilaria species, G. hirsuta Rosso et al., 2018 and G. polita Rosso et al., 2018. Both species differ from the new species by having erect avicularia, and a different number of oral spines (six in G. hirsuta and five in G. polita).Published as part of Ramalho, Laís V., Moraes, Fernando C., Salgado, Leonardo T., Bastos, Alex C. & Moura, Rodrigo L., 2021, Bryozoa from the reefs off the Amazon River mouth: checklist, thirteen new species, and notes on their ecology and distribution, pp. 1-45 in Zootaxa 4950 (1) on pages 11-13, DOI: 10.11646/zootaxa.4950.1.1, http://zenodo.org/record/464324
Solitude peopled: the representation of the orthonym in Fernando Pessoa\'s poetic work
No full textO presente trabalho procura contemplar a representação da figura que tradicionalmente conhecemos pelo nome de ortônimo, dentro da obra de Fernando Pessoa. Segundo os mais recentes estudos sobre o assunto, esse sujeito tem, na ficção heteronímica, um estatuto semelhante ao de Caeiro, Campos ou Reis. Nossa hipótese vai no sentido contrário e defende que, diferentemente dessas três personagens, o ortônimo é portador de uma dupla natureza compartilhando, ao mesmo tempo, o estatuto de autor e personagem. Para explicar como isso se dá fazemos uma análise dividida em duas partes. Na primeira, nos detemos na prosa de Pessoa, procurando delimitar o papel do ortônimo dentro da ficção heteronímica. Na segunda, fazemos um estudo comparativo entre certos aspectos da poesia heteronímica e ortonímica, procurando mostrar como estatuto do eu que fala nessa última se afasta do mundo ideal dos heterônimos para figurar uma experiência literária que, em última instância, propõe uma reflexão a respeito do papel do autor dentro da obra.This thesis contemplates the representation of the orthonym in Fernando Pessoa´s poetic work. Recent studies defend the idea that it should have, in Pessoa´s fiction, the same status as the others heteronyms, Caeiro, Reis e Campos. We, however, disagree with that approach. Instead, we believe that the orthonym has a double status and can be understood also as a representation of the author in Pessoa´s work. In order to explain how this is possible, we make an analysis in two parts. First, we study Pessoa´s prose, trying to understand what is the orthonimic´s role in the heteronimic´s fiction. Then we make a comparative study of certain aspects of Pessoa´s poetry. Doing so, we intent to show that, while the heteronyms are represented as pure literary beings, the orthonym depicts the author´s literary experience
