The truth of personal names
No full textPortuguese-speakers, when asked about their personal names, often respond with a notion of the
‘truth of’ their names. Basing itself on ethnographic data collected by the author in Macao (southern
China), Bahia (Brazil), and Portugal, the article interprets this notion of truth as a form of ontological
weighing that postulates the unitariness of the person by reference to a subjection to a bureaucratic
order and to a cultural and linguistic universe associated to it
Clusia nitida Bittrich & F. N. Cabral 2013, sp. nov.
No full textClusia nitida Bittrich & F. N. Cabral, sp. nov. (sect. Phloianthera) (Fig. 1 & Fig. 2) Diagnosis: Similar to Clusia microstemon, but dry leaves are darker coloured and generally have a shiny surface, the latex channels are denser on the adaxial surface, the midrib is conspicuous as far as to the apex, the petal colour is different and anthers are absent on the lateral part of the disk-like androecium. The new species is also similar to Clusia myriandra from which it differs by the leaf shape, the visibility of the latex channels on the leaves, the shorter peduncle and basal internodes in the inflorescence, the size of the fruits and the lesser number of seeds. Type:— BRAZIL. Roraima: Caracaraí, Parque Nacional do Viruá, White-sand vegetation, 1º24’50.7”N, 60º59’16.5”W, 59 m, 15 October 2010, F.N. Cabral & V . S. Santos 298 (holotype INPA!). Trees, small trees or shrubs up to 6 m tall; sometimes with prop roots. Plants dioecious, latex white or cream; young branches cylindrical or more frequently subangular, surface not rugulose, but finely sulcate or with tiny longitudinal foldings, linear colleters present in the petiole axils, deciduous with the leaves. Petiole 4.0–16.0(– 17.0) mm long, margin flat to revolute. Leaf blade coriaceous, discolorous, adaxial surface dark brown and shiny in sicco, oblong-elliptic, 40–85(–108) mm long and (18–)21–49(–53) mm wide, apex rounded, base attenuate, margin revolute; midrib prominent on the adaxial surface and conspicuous as far as the apex, secondary veins prominent on both surfaces, with (9–)12–26(–29) pairs, 1.5–4.0 mm distant from each other and at an angle of 35º–40º with the midrib, basal veins inconspicuous; latex canals concolorous on the adaxial surface or slightly darker than the blade, immersed, 0.3–0.7 mm distant from each other, flat to protruding on the abaxial surface, 0.8–1.0 mm distant from each other, forming an angle of about 25º with the midrib. Inflorescence cymose, compact, 3–9-flowered (staminate plants) or 3–7-flowered (pistillate plants), bracts and bracteoles united at the base, hemiorbicular, ca. 2 mm long, pedicels very short, ca. 2 mm long, quadrangular. Epicalyx bracts 2 (+2), united at base, sepals 4 (2+2), rarely 5 or 6 (2+3, 3+3), ± suborbicular, ca. 4–8 mm long and 4–8 mm wide. Petals 5–8, 6–13 x 6–12 mm, dark bordeaux or blood-red. Staminate flower with the androecium forming a thick, circular, flat disk, ca. 3–6 mm wide, composed of about 300 densely compact stamens, the upper surface covered by a mixture of resin and pollen during anthesis, filaments 2.3–3.0 mm long, lateral region of the disk without anthers, anther dehiscence by apical or transverse slits. Pistillate flower with 3 or 4 series of staminodes around the base of the ovary, secreting resin at the apex; staminodes linear, 1.3–2.0 mm long, truncated at the apex, without sterile anthers; stigmas 4 or 5, apical, yellowish, obtusely triangular, flat, 2.5 mm long; ovary yellow, ovules 1 or 2(–3) per locule. Immature fruit oval to hemispherical, 15–22 x 13–19 mm, usually finely longitudinally striate with latex canals; sepals, staminodes and stigmas persistent, valve endocarp not conspicuously hardened. Seeds 1 or 2(–3) per locule, 5.0–9.0 x 3.5–5.0 mm, green, aril orange. Comparison: —The most similar species is C. microstemon Planchon & Triana (1860: 331), which sometimes occurs sympatrically, and with which C. nitida has been confused. It has a wide distribution in the Amazon. The main difference between the species is the male androecium, which in C. microstemon has anthers at the lateral side of the androecial disk, whereas C. nitida has anthers only on its top. Other differences include the darker colour and the glossy appearance of the leaf surfaces in sicco in C. nitida; the androecium size, which is larger in C. microstemon; the flower colour, in C. microstemon the petals are reddish to pinkish-purple in the centre and white-pink on the edge and the calyx is white-pink, while in C. nitida the petals are dark bordeaux or blood-red and the calyx is green; C. microstemon has 4 or 5 ovules per locule, whereas C. nitida has only 1 or 2(–3) ovules per locule; the fruits of C. microstemon are slightly ovoid and in C. nitida they are generally cylindrical, and finally, C. microstemon has a lower density of latex channels on the leaves than in C. nitida and the midrib becomes invisible in the apical part of the leaves. Another similar species is C. myriandra (Bentham 1843: 368) Planchon & Triana (1860: 332) from the Guianas, which has a very similar androecium. However, C. myriandra has elongated and oblanceolate leaves, unlike C. nitida, which has shorter and more rounded broader leaves; the latex channels of the leaves, which are easily visible in C. nitida, are invisible in the strongly coriaceous leaves of C. myriandra; the peduncle and the basal internodes in the inflorescence are much longer in C. myriandra, positioning the inflorescence above the foliage and C. myriandra has more elongated and larger fruits than C. nitida with 10 or more seeds per locule, while the fruit locules of C. nitida have only 1 or 2(–3). Etymology: —Latin nitidus = shiny, because the dried leaves generally have a conspicuously shiny surface, different from those of C. microstemon, the leaf surface of which is typically dull. Distribution and habitat: —In Brazil, Clusia nitida is known from the North Region, in the states of Amazonas and Roraima. Apparently, it has not yet been collected outside of Brazil. It mainly occurs in whitesand vegetation and at river margins in Amazonian lowlands. Additional specimens examined (paratypes): — BRAZIL.

Espelhamentos e antagonismos serão ainda cotejados a partir da análise de poemas de ambos os poetas, em especial o modo como Cabral passa a articular elementos memorialísticos, representações do Recife e referências a Joaquim Cardozo em sua poética a partir de O engenheiro (1945).Palavras-chave: João Cabral de Melo Neto; Joaquim Cardozo; Recife; Poesia Brasileira.Abstract: This article searches to investigate the influence of the poet and engineer Joaquim Cardozo on João Cabral de Melo Neto’s work, rebuilding the course of this relationship that had begun in Recife, in the late 1930s, outspread along more than four decades in Cabral’s career. Correspondences and differences will be present in the analysis of poems of both writers, especially in the way that Cabral articulates memories, representations of Recife and references to Joaquim Cardozo in his poetics since O engenheiro (1945).Keywords: João Cabral de Melo Neto; Joaquim Cardozo; Recife; Brazilian poetry
In vitro comparative evaluation of piezoelectric and magnetostrictive ultrasonic instrumentation in the furcation area
No full textBackground and Aim: Non-surgical periodontal therapy plays a key role in the management of elements suffering furcation involvement. This study has the objective to compare the effectiveness between piezoelectric and magnetostrictive tools and the various tips in an arti- ficial model of multiradicular tooth.
Methods: A plastic tooth, which perfectly mimics a first upper molar, was inserted into an experimental model. This model consisting of a container with silicone material inside, with the tooth covered from the apex to 2 mm from furcation roof configured to simulate a grade two furcation defect. The treating root area was covered with specific material to simulate the presence of calculus. Pictures were taken before and after instrumentation. The experimental procedure con- sists of ultrasonic roots cleaning in four groups (piezoelectric straight- tip, piezoelectric curved-tip, magnetostrictive straight-tip, magneto- strictive curved-tip) for a standardised time. For the vestibular, distal and medial surfaces 3000 and 1500 for the palatal surface. The instru- mentation operation was repeated 15 times for each group. The anal- ysis of the amount of calculus surface before and after treatment was performed by the analysis of the pictures using CAD software. Results: The validity of piezoelectric and magnetostrictive instrumen- tation in cleaning root surfaces is evident for both. All root surfaces covered were compared before and after instrumentation and were always statistically significant (p ≤ 0.001). It was possible to compare the piezoelectric and magnetostrictive instrumentation with the straight tips and the curved tips, and establish the best performance. The magnetostrictive instrumentation, in particular with the curved tip, reports significant values (p < 0.005).
Conclusions: With the limitations of the preliminary in vitro study, we can conclude that modern ultrasonic instrumentation, both piezoelectric and magnetostrictive, is an excellent tool for the maintenance of multi- rooted teeth. Particularly the promising results of magnetostrictive ultra- sonic scaler with curved tips will be validated with in vivo studies
Parâmetros micrometeorológicos relacionados às doenças da seringueira em Manaus (AM).
No full textMedidas de temperatura e umidade do ar, radiação solar e térmica, velocidade e direção do vento foram realizadas, a cada 10 min, em um cultivo experimental de seringueira do clone Fx 3899 (hibrido Hevea brasiliensis x H. benthamiana) com kudzu tropical (Pueraria phaseoloides) entre linhas de plantio. A temperatura do ar variou entre 20oC e 30oC e a umidade relativa entre 90% e 99%, durante os ciclos diários. A penetração de radiação no seringal chegava a máximas de 60% para radiação solar (ondas curtas) e 70% para o saldo de radiação (ondas curtas e longas). Com isso, o kudzu tropical, por evapotranspiração, faz aumentar o teor de umidade na base das copas das seringueiras. Condições de microclima altamente favoráveis aos fungos patogênicos ocorreram geralmente durante a noite e, às vezes, durante o dia por advecção de umidade proveniente da floresta nativa adjacente

Cabral: Drummond, à sua maneira
No full textEste estudio trata de un análisis de los primeros poemas escritos por Joao Cabral de Melo Neto a la luz de la influencia que recibió del poeta Carlos Drummond de Andrade. Con este fin, se discuten los conceptos desarrollados por Harold Bloom en su teoría de la influencia poética, aliándose a la prosa crítica de Cabral, desarrollado principalmente en el trabajo "La poesía y la composición" de 1952. Hemos analizado la
correspondencia entre ambos autores, que creemos, con John Gledson, que esta relación "es uno de los temas más fascinantes y más importante en la historia de la poesía en Brasil".O presente trabalho buscou uma análise dos primeiros poemas escritos por João Cabral de Melo Neto à luz da influência que este recebeu do poeta Carlos Drummond de Andrade.

Effects of Different Fibre Alignments and Bioactive Coatings on Mesenchymal Stem/Stromal Cell Adhesion and Proliferation in Poly (ɛ-caprolactone) Scaffolds towards Cartilage Repair
No full textIn this work, 3D biodegradable poly (epsilon-caprolactone) scaffolds with high porosity and interconnectivity were produced by extrusion and characterized in terms of their structural and mechanical properties. The effects of scaffold fibre alignment (0-45 degrees and 0-90 degrees) and of different adhesive coatings (Fibronectin, Gelatin and commercially available CELLstart (TM)) on bone marrow mesenchymal stem/stromal cells adhesion, migration and proliferation were evaluated using AlamarBlue (TM) assay. Fibronectin and CELLstart (TM) coated poly (epsilon-caprolactone) scaffolds presented an improvement in cell adhesion of approximately 2-fold relatively to the non-treated scaffolds, independently of fibre alignment. Overall, all the conditions studied promoted the growth and migration of bone marrow mesenchymal stem cells in the fabricated poly(epsilon-caprolactone) scaffolds, without affecting their chondrogenic differentiation and extracellular matrix deposition evaluated by Alcian Blue staining.
