Colour in life (Figures 4 and 6) Ground colouration of head and body usually bright orange, with narrow whitish or yellowish vertical bars, the first in the interorbital region.

Cheek with a white ocellus surrounded by black. Fins orange. Colour of preserved material Head and body yellowish white, with 10 – 13 narrow vertical brownish bars (Figure 1). 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

O LETRAMENTO PARA ALUNOS SURDOS: METODOLOGIAS EM USO
No full textEste trabalho pretende refletir sobre o letramento de alunos surdos, que são, muitas vezes, tratados como sujeitos linguisticamente deficientes, incapazes de expressar com clareza uma ideia por escrito ou de compreenderem o que leem. Neste artigo, tecemos algumas considerações, orientadas pela literatura de estudiosos como Balieiro (2008), Brito (1993), Damazio, (2005), Gesueli (1988) e Kober (2008), a fim de investigar metodologias de letramento utilizadas pelos professores para alunos surdos, avaliar os benefícios do letramento bilíngue para eles e investigar a utilização de métodos visuais de ensino. Os resultados desta pesquisa mostram que os métodos orais, utilizados na maioria das escolas públicas, não têm contribuído para o desenvolvimento cognitivo da pessoa surda, enquanto a Língua Brasileira de Sinais possibilita a eles competências comunicativas fundamentais

"Mentores da nacionalidade" : a apropriação das obras de Euclides da Cunha, Alberto Torres e Farias Brito por Plínio Salgado
No full textO trabalho trata da apropriação das obras de Euclides da Cunha, Alberto Torres e Farias Brito por Plínio Salgado, líder da Ação Integralista Brasileira (AIB), na década de 1930. Tais autores eram citados em conjunto pelo líder da AIB para justificar uma referência eminentemente nacional do integralismo. Procurou-se analisar a leitura particular que Salgado fez do pensamento e da biografia desses pensadores, tendo como referência outras apropriações feitas por intelectuais da geração de Salgado, bem como os estudos mais recentes que se ocuparam em interpretar as idéias daqueles autores.This paper deals with the appropriation of Euclides da Cunha’s, Alberto Torres’s and Farias Brito’s work by Plínio Salgado, the Ação Integralista Brasileira (AIB) leader, in the 1930’s. These authors were quoted as a whole by the AIB leader to justify an exclusively national reference to integralismo. We tried to analyse the personal reading that Salgado made of these authors thoughts and biography, having as a reference other appropriations made by intellectuals of Salgado’s generation, as well as the latest studies that tried to interpret these authors ideas

Chemical physics of controlled wettability and super surfaces
No full textWetting phenomena are widespread in both natural and technological contexts.
Despite the well-established nature of this scientific field and our extensive
knowledge of its underlying principles, wetting remains a dynamic and vibrant
area of study. It continues to pose fundamental questions while offering
innovative avenues for controlling these phenomena to develop novel
applications.
By tailoring the wetting properties of surfaces, researchers and engineers
can design materials with specific functionalities, such as self-cleaning
surfaces, anti-fog coatings, and enhanced slipperiness. Recent years have
witnessed significant advancements in wetting research, owing to the exquisite
control achieved in surface topography and chemistry and to the development of
novel experimental techniques. Additionally, simulations and theory have played
a crucial role in these advancements. They provid the fundamental knowledge and
quantitative tools to control wettability and design surfaces with enhanced
properties.
Given these recent breakthroughs, this special collection Chemical Physics of
Controlled Wettability and Super Surfaces becomes particularly timely and
significant. It serves as a platform to showcase some of the latest
developments in the field of wetting. It highlights the exciting progress and
potential applications in controlling wetting properties that are enabled by
the synergy between theory, simulations, and experiments.Comment: EDITORIAL: Special Topic: Chemical Physics of Controlled Wettability
