Obras poéticas de José Antonio de Brito
L'ouvrage est bilingue français / portugaisInternational audienceLa courte vie de José Antonio de Brito s’est écoulée dans le milieu d’un XVIIIe siècle portugais très fortement marqué par un ancien régime décadent. La flatterie obligée des grands nuisait alors à la production littéraire. Les poèmes de José Antonio de Brito se ressentent de ces obligations mais ils expriment cependant, dans une langue sans afféterie contrastant avec le style ampoulé de l’époque, une réflexion ironique, une autodérision qui n’ est pas dénuée de profondeur. Appréciée par ses contemporains, sa poésie n’a pourtant jamais été imprimée. L’opportunité d’achat d’un manuscrit de ses œuvres permet, quelque 250 ans plus tard, de combler cette lacune et de livrer à la curiosité ce témoignage d’ une époque mal connue
A monoclinic modification of propane-1,3-diyl bis(pyridine-3-carboxylate)
In the title compound, C15H14N2O4, (I), the molecule lies on a twofold rotation axis which passes through the central C atom of the aliphatic chain, giving one half-molecule per asymmetric unit. The structure is a monoclinic polymorph of the triclinic structure previously reported [Brito, Vallejos, Bolte & López-Rodríguez (2010). Acta Cryst. E66, o792], (II). The most obvious difference between them is the O/C/C/C—O/C/C/C torsion angle [58.2 (7)° in (I) and 173.4 (3)/70.2 (3)° in (II) for GG and TG conformations, respectively]. Another important difference is observed in the dihedral angle between the planes of the aromatic rings [86.49 (7)° for (I) and 76.4 (3)° for (II)]. The crystal structure features a weak pi–pi interaction [centroid–centroid distance = 4.1397 (10)Å]; this latter kind of interaction is not evident in the triclinic polymorph

Generic and speci W c identi W cation. These specimens from the Cape Verdes correspond in diagnostic features to the original description of this species by Van Tassell et al. (1988), based on material from the Canaries and Guinea. Their meristic features are D1 VI, D2 I /10 (10±11), A I /9, P 18 (17±18), and LL 24±27. Biology. At the Cape Verdes localities, the species was collected in 11±16 m on mixed substrata of sand, stones, calcareous algae, and rock, within a depth range of 9±45 m noted elsewhere (Van Tassell et al., 1988). The ®nding of V. canariensis at the Cape Verdes supports the suggestion by Van Tassell et al. (1988) that this is a tropical species whose northern limit of distribution now appears to be at Madeira (Debelius, 1998).Published as part of Brito, A. & Miller, P.

Nape with small white spots. Cheek with a white ocellus surrounded by black, and with a small black spot in the middle. Fins translucent. Etymology Tonstricula (Latin) means little female barber. The name refers to the cleaning behaviour of the new species. Comparison The Diplecogaster-ctenocrypta group, comprising the species D. ctenocrypta and D. tonstricula n. sp., is characterised by a high number of 9 rays in the dorsal fin and 8 in the anal fin (other species of the genus: 4 – 8 rays in the dorsal fin, 3 – 7 rays in the anal fin), and the position of the anus which is situated closer to the anal-fin origin than to the end of the disc (other species of the genus: situated in the middle between disc and anal-fin origin). Species of the group are further distinguished from D. bimaculata, D. euxinica and D. pectoralis in having 14 – 15 caudal-fin rays (18 – 21 in D. bimaculata, D. euxinica and D. pectoralis), and lacking lateral papillae in disc region A (many lateral papillae present in D. bimaculata, D. euxinica and D. pectoralis), and from D. megalops in 13 – 16 rakers on third gill arch (7 – 9 rakers in D. megalops). Diplecogaster tonstricula n. sp. differs from D. ctenocrypta by having the pelvic disc without lateral papillae in region A (lateral papillae present in D. ctenocrypta), disc region B with 2 rows of papillae (5 rows in D. ctenocrypta), lacking mandibular pores (one mandibula pore present in D. ctenocrypta), principal caudal-fin rays 14 – 15 (16 rays in D. ctenocrypta), the interorbital distance 4.1 – 4.6 in head length (5.4 in head length in D. ctenocrypta), the distance between disc and anus 14 – 17% of SL (19% of SL in D. ctenocrypta), and 13 – 16 rakers on third gill arch (18 in D. ctenocrypta). The live colour pattern of D. ctenocrypta is unknown, but the holotype is pale, without traces of bands, while the head and body of Diplecogaster tonstricula n. sp. is covered with 10 – 13 bars. The species of Diplecogaster may be distinguished with an identification key (see above). Counts and proportions of the species of the genus are compared in Table 1. Distribution and habitat Eastern Atlantic Ocean: Canary Islands (El Hierro, Tenerife, Fuerteventura), Senegal (Dakar). Probably more widespread in the region. The species was collected and observed at 10 – 38 m depth, mainly on hard substrate. It was observed to act as a facultative cleaner of larger fishes (Figure 5, Senegal, cleaning a muraenid, Gymnothorax afer; Brito et al. (2002, figures 364 – 366), Canary Islands, cleaning a muraenid and a serranid). Remarks The new species was classified in the genus Diplecogaster as it agrees with the generic characters given by Briggs (1955) as 3½ gills, the gill membranes attached to the isthmus, the disc double, the dorsal and anal fins with strong rays, normal, the subopercular region without a spine, 24 – 25 pectoral fin rays, the absence of incisors or welldeveloped canines, and 13 – 16 rakers on the third gill arch. It is a member of the Diplecogaster-ctenocrypta group (comprising D. ctenocrypta and D. tonstricula n. sp.), which is characterised within the genus by a high number of 9 rays in the dorsal fin and 8 rays in the anal fin, and the position of the anus which is situated closer to the anal-fin origin than to the end of the disc. The species was first described and illustrated by Brito et al. (2002, p. 281, figures 364 – 366) from the Canary islands, but it was confused by authors with Diplecogaster ctenocrypta Briggs 1955. A recent examination of the holotype of that deep-water species (ZMUC P9037) provided evidence that this is a separate species. Cleaning behaviour has previously been observed in other gobiesocid fishes. Patzner and Debelius (1984) photographed a specimen of Diplecogaster bimaculata cleaning a moray eel, Muraena helena. Hutchins (1991) described Cochleoceps bicolor from southern and south-western Australia, and C. orientalis from south-eastern Australia, as setting up cleaning stations to remove parasites of other teleosts. Weitzmann and Mercader (2012) reported an observation of Lepadogaster candolii in the north-western Mediterranean Sea which was cleaning a grouper, Epinephelus marginatus.Published as part of Fricke, Ronald, Wirtz, Peter & Brito, Alberto, 2015, Diplecogaster tonstricula, a new species of cleaning clingfish (Teleostei: Gobiesocidae) from the Canary Islands and Senegal, eastern Atlantic Ocean, with a review of the Diplecogaster-ctenocrypta species-group, pp. 731-748 in Journal of Natural History 50 on pages 737-743, DOI: 10.1080/00222933.2015.1079659, http://zenodo.org/record/398973
MeSH term explosion and author rank improve expert recommendations
Information overload is an often-cited phenomenon that reduces the productivity, efficiency and efficacy of scientists. One challenge for scientists is to find appropriate collaborators in their research. The literature describes various solutions to the problem of expertise location, but most current approaches do not appear to be very suitable for expert recommendations in biomedical research. In this study, we present the development and initial evaluation of a vector space model-based algorithm to calculate researcher similarity using four inputs: 1) MeSH terms of publications; 2) MeSH terms and author rank; 3) exploded MeSH terms; and 4) exploded MeSH terms and author rank. We developed and evaluated the algorithm using a data set of 17,525 authors and their 22,542 papers. On average, our algorithms correctly predicted 2.5 of the top 5/10 coauthors of individual scientists. Exploded MeSH and author rank outperformed all other algorithms in accuracy, followed closely by MeSH and author rank. Our results show that the accuracy of MeSH term-based matching can be enhanced with other metadata such as author rank
2-Phenylethyl 1-thio-β-d-galactopyranoside hemihydrate
The title compound, C14H20O5S·0.5H2O, crystallizes with two organic molecules and a solvent water molecule in the asymmetric unit. In both molecules, the hexapyranosyl rings adopt a slightly distorted chair conformation (5 C 2) with four substituents in equatorial positions and one substituent in an axial position. The main difference between the organic molecules is the dihedral angle between the phenyl ring and the best plane defined by the O—C1—C2—C3 atoms (r.m.s deviations = 0.003 and 0.043 Å) of the hexapyranosyl rings [47.4 (4) and 86.5 (4)°]. In the asymmetric unit, molecules are linked by two strong O—H[cdots, three dots, centered]O hydrogen bonds. In the crystal, the components are linked by a total of 10 distinct O—H[cdots, three dots, centered]O hydrogen bonds, resulting in the formation of a two-dimensional network parallel to the ab plane
Entre primos : d'«O primo João de Brito» a «O Primo Basílio»
This article demonstrates that there are close genetic relations between the ms. O Primo Joao de Brito and the novel O Primo Basilio by Eca de Queiros; although much shorter than the novel, the ms. offers a plot and character development and a use of narrative technique which allow us to determine its genetic proximity to O Primo Basilio: we are thereby given insights into the workings of its author
Systematic reviews with language restrictions and no author contact have lower overall credibility: a methodology study
Zhen Wang,1–3 Juan P Brito,4 Apostolos Tsapas,5 Marcio L Griebeler,4 Fares Alahdab,1,3 Mohammad Hassan Murad,1,3,61Robert D and Patricia E Kern Center for the Science of Health Care Delivery, 2Division of Health Care Policy and Research, Department of Health Sciences Research, 3Knowledge and Evaluation Research Unit, 4Division of Endocrinology, Diabetes, Metabolism, and Nutrition, Mayo Clinic, Rochester, MN, USA; 5Aristotle University of Thessaloniki, Thessaloniki, Greece; 6Division of Preventive, Occupational and Aerospace Medicine, Mayo Clinic, Rochester, MN, USABackground: High-quality systematic reviews (SRs) require rigorous approaches to identify, appraise, select, and synthesize research evidence relevant to a specific question. In this study, we evaluated the association between two steps in the conduct of an SR – restricting the search to English, and author contact for missing data – and the overall credibility of a SR.Methods: All SRs cited by the Endocrine Society's Clinical Practice Guidelines published from October 2006 through January 2012 were included. The main outcome was the overall A Measurement Tool to Assess Systematic Reviews (AMSTAR) score, as a surrogate of SR credibility. Nonparametric Kruskal–Wallis tests and multivariable linear regression models were used to investigate the association between language restriction, author contact for missing data, and the overall AMSTAR score.Results: In all, 69 SRs were included in the analysis. Only 31 SRs (45%) reported searching non-English literature, with an average AMSTAR score of 7.90 (standard deviation [SD] =1.64). SRs that reported language restriction received significantly lower AMSTAR scores (mean =5.25, SD =2.32) (P<0.001). Only 30 SRs (43%) reported contacting authors for missing data, and these received, on average, 2.59 more AMSTAR points (SD =1.95) than those who did not (P<0.001). In multivariable analyses, AMSTAR score was significantly correlated with language restriction (beta =-1.31, 95% confidence interval [CI]: -2.62, -0.01, P=0.05) and author contact for missing data (beta =2.16, 95% CI: 0.91, 3.41, P=0.001). However, after adjusting for compliance with reporting guidelines, language restriction was no longer significantly associated with the AMSTAR score.Conclusion: Fewer than half of the SRs conducted to support the clinical practice guidelines we examined reported contacting study authors or searched non–English literature. SRs that did not conduct these two steps had lower quality scores, suggesting the importance of these two steps for overall SR credibility.Keywords: evidence-based medicine, research design, validity, quality of evidenc
