Diversidade de cefalópodes e o seu papel no nicho trófico de seus principais predadores nos Arquipélagos de Fernando de Noronha e São Pedro e São Paulo

This study aims, to characterize the diversity of cephalopods by analyzing the stomach contents of fishes caught in the islands of St. Peter and St. Paul (ASPSP) and Fernando de Noronha (AFN). Also, verify the participation of cephalopods in the diet of their main predators. A total of 723 stomachs were collected, from 8 species of fish, caught by the fishery, 471 stomachs were from ASPSP and 252 were from the AFN. It was recorded the occurrence of food items (fish, cephalopods and crustaceans) and the cephalopods were identified to the lowest taxa possible, according to specialized literature. The Ommastrephidae family represented 84.46% of occurrence in the ASPSP and 63.48% in the AFN, confirming the importance of this family in the area studied and also in the diet of their predators. Among the species with greatest occurrence Ornitoteuthis antillarum was the most representative in both regions. This species had an average mantle length of 54.25 mm, thus demonstrating that the majority of this population is in the juvenile stage of development. The smallest species found was Argonauta nodosa with a mantle length of 4.06 mm and the largest was Ommastrephes bartrami, with 223.33 mm. In the AFN, the species richness (d) was 2.318, the diversity index (H ') was 1.454 and the measure of evenness (J) was 0.585. In the ASPSP, the species richness (d) was 2.66, the Shannon diversity index (H ') was 1.013 and the measure of evenness (J) was 0.373. AFN has a greater cephalopod diversity than ASPSP, confirming the pattern suggested by the Theory of Island Biogeography. Among the occurrence of prey items for all predators, the cephalopods are secondary preys. The most important cephalopod species in the diet of Thunnus albacares and Acantocybium solandri was Ornithoteuthis antillarum. These predators have different niche width the diet of Thunnus albacares is more specialized, but they have an overlap of 84.684% in the trophic niche, suggesting that in the ASPSP these two species may use similar niches

Análise dos microssismos registrados no arquipélago de São Pedro e São Paulo (ASPSP) e suas relações com variáveis oceanográficas

Microseisms are continuous vibrations pervasively recorded in the mili Hertz to 1 Hz frequency range. These vibrations are mostly composed of Rayleigh waves and are strongest in the 0.04 to 1 Hz frequency band. Their precise source mechanisms are still a matter of debate but it is agreed that they are related to atmospheric perturbations and ocean gravity waves. The Saint Peter Saint Paul Archipelago (SPSPA) is located in the equatorial region of the Atlantic Ocean about 1,100 km distant from the Brazilian northeastern coast. The SPSPA is composed by a set of several small rocky formations with a total area of approximately 17,000 m². Due to its remote distance from the continent and the lack of cultural noise, this location is a unique location for measuring microseismic noise and to investigate its relation with some climate and oceanographic variables. In the SPSPA we have recorded both primary microseisms (PM) at 0.04 – 0.12 Hz and the secondary microseisms (SM) at 0.12 – 0.4 Hz during 10 months in 2012 and 2013. Our analysis indicates a good correlation between the microseismic noise in the region and a seasonal dependency. In particular, the winter in the northern hemisphere. We have also shown that most of the PM is generated in the SPSPA itself. The SM source location depends with the seasonal climatic and oceanographic variables in the northern hemisphere

Caracterização e comparação de genes expressos em ápices meristemáticos de cana-de-açúcar cultivados em SP e RN

In this work, we used sugarcane as a model due to its importance for sugar and ethanol production. Unlike the current plant models, sugarcane presents a complex genetics and an enormous allelic variation. Here, we report the analysis of SAGE libraries produced using the shoot apical meristem from contrasted genotypes by flowering induction (non-flowering vs. early-flowering varieties) grown under São Paulo state conditions. The expression pattern was analyzed using samples from São Paulo (SP) and Rio Grande do Norte (RN) states. These results showed that cDNAs identified by SAGE libraries had differential expression only in São Paulo state samples. Furthermore, the cDNA identified CYP (Citocrome P450) was chosen for in silico and genome characterization because it was found in SAGE libraries and subtractive libraries from samples from RN. Phylogenetic trees showed the relationship for these sequences. Furthermore, the qRT-PCR for CYP showed a potential role as flowering indutor for RN samples considering different isophorms. Considering the results present here, it can be consider that CYP gene may be used as molecular marker

Levantamento cariotípico em espécies de peixes marinhos costeiros de fundo arenoso (Osteichthypes, Perciformes)

Cytogenetics analyses in fish are important because they compose a private group among the vertebrates, occupying a central position in the animal evolution. The Perciforms Order, dominant in the marine and freshwater environment, it constitutes a model potentially useful in the genetic evaluation of populations, as well as in the understanding of its evolutionary processes. In spite of this, cytogenetics studies in this great group is scarce, above all for the inhabitants of sandy bottom and pelagics habits. The present work proposed to contribute for the cytogenetic characterization of nine species of fish marine of sandy bottom of the coast of Rio Grande do Norte (Brazil), identifying the evolutionary patterns related to the karyotype in these species and the existence of filogenetics affinities between them and other Perciformes. The animals were collected in the beaches of the Redinha, Ponta Negra and Búzios (Coast of Rio Grande do Norte) and in Saint Peter and Saint Paul Archipelago. Later on they were submitted to the cytogenetics technical that consist of mitotic estimulation, obtaining of mitotics chromosomes, proceeded by techniques of conventional coloration (Giemsa) and chromosomic bands (Ag-RONs and C band). Diploid number and fundamental number equal to 48 were observed in most of the species: Menticirrhus americanus, Ophioscion punctatissimus, Pareques acuminatus (Sciaenidae); Chloroscombrus chrysurus (Carangidae); Echeneis sp. 2 (Echeneidae); Archosargus probatocephalus (Sparidae) and Orthopristis ruber (Haemulidae). Trachinotus goodei (NF=52) (Carangidae) and Echeneis sp. 1 (Echeneidae) (NF=54) presented variation in NF, staying constant a diploid number equal to 48. RONs was situated in pericentromeric position in whole the scianids, and in the species Echeneis sp. 2 (22° pair), O. ruber and A. probatocephalus (1° pair), coinciding with great heterocromatics blocks in M. americanus (1° pair), P. acuminatus (2° pairl) and O. ruber (1° pair). RONs was also located in the telomeric area of the short arm of the 5° and 11° acrocentrics pairs in T. goodei, 4° and 19° pairs of C. chrysurus, 1° pair (sm) of Echeneis sp. 1. The C band detected centromeric blocks in most of the chromosomes of the species of Sciaenidae, Carangidae and Echeneidae, with great blocks in A. probatocephalus (4° pair). Heterocromatic blocks in telomeric areas in submetacentrics of Echeneis sp. 1, and pericentromerics in M. americanus (1° and 8° pairs), O. punctatissimus (1° pair) and P. acuminatus (2° pair) were also observed. It is noticed a marked conservatism cromossomic in the species of the family Scianidae and Haemulidae in what says respect to the number of acrocentrics chromosomes and the location of RONs. Even so it is outstanding the presence of heterocromatinization events during the karyotypic evolution of this family. Already in the families Sparidae and Carangidae, the obtained results reaffirm examples of small variations structural resultants of inversion and translocation Robertsonian, as important mechanisms of diversification karyotipical, as well as a pattern numerical evolutionary conserved, also observed in representatives of Echeneidae of Atlantic in relation to Pacific. The presence of RONs multiple, observed in the species T. goodei and C. chrysurus seems to represent a character derived in the family Carangidae. The results for the species O. ruber and A. probatocephalus suggest the presence of possible geographical or climatic barriers among populations of NE of Brazil in relationship the one of the SE

Prevalence of refractive errors in students in Northeastern Brazil

To determine the prevalence of refractive errors in the public and private school system in the city of Natal, Northeastern Brazil. Methods: Refractometry was performed on both eyes of 1,024 randomly selected students, enrolled in the 2001 school year and the data were evaluated by the SPSS Data Editor 10.0. Ametropia was divided into: 1- from 0.1 to 0.99 diopter (D); 2- 1.0 to 2.99D; 3- 3.00 to 5.99D and 4- 6D or greater. Astigmatism was regrouped in: I- with-the-rule (axis from 0 to 30 and 150 to 180 degrees), II- against-the-rule (axis between 60 and 120 degrees) and III- oblique (axis between > 30 and < 60 and >120 and <150 degrees). The age groups were categorized as follows, in: 1- 5 to 10 years, 2- 11 to 15 years, 3- 16 to 20 years, 4- over 21 years. Results: Among refractive errors, hyperopia was the most common with 71%, followed by astigmatism (34%) and myopia (13.3%). Of the students with myopia and hyperopia, 48.5% and 34.1% had astigmatism, respectively. With respect to diopters, 58.1% of myopic students were in group 1, and 39% distributed between groups 2 and 3. Hyperopia were mostly found in group 1 (61.7%) as well as astigmatism (70.6%). The association of the astigmatism axes of both eyes showed 92.5% with axis with-the-rule in both eyes, while the percentage for those with axis againstthe- rule was 82.1% and even lower for the oblique axis (50%). Conclusion: The results found differed from those of most international studies, mainly from the Orient, which pointed to myopia as the most common refractive error, and corroborates the national ones, with the majority being hyperopia

Interface cena e tecnologia : composições cênicas mediadas

Based on the presupposition that the arts in the West always counted on resources, supports, and devices pertaining to its time context, an reflection is intended regarding the scenic compositions mediated by digital technologies do. Such technologies are inserted in the daily routine, also composing artistic experiments, thus playing a dialogical role with the art/technology intersection. Therefore, the proposal is to investigate what relationships are established in the contemporary theatrical scene from the contagion by digital technologies, aiming at establishing this parallel through a dialogue with the authors discussing the subject, and also based on the group practices having technological resources as a determinant factor in their plays. Furthermore, a reflection should be made on the scene that incorporates or is carried out in intermediatic events, analyzing how digital technologies (re)configure compositional processes of the plays by GAG Phila7, in the city of São Paulo/SP. For such, the dissertation is organized in three sections comprising four moments, to wit: brief overview of the field, contextualization, poetic analysis and synthesis. Qualitative methods are used as the methodological proposal: semi-structure interview, note and document taking (program, website, playing book, disclosure material for advertising text, photographs, and videos). Within the universe of qualitative research, it works with the epistemological perspective of the Gadamer philosophical hermeneutics. The possibilities allowed by the double virtual (Internet/web) generated a type of theater with another material basis and new forms of organization and structure, being possible to perceive that such technological advances and the arts are mutually contaminated, generating a dislocation in the logics of theatrical composition, movement beginning with the artistic vanguards, gradually intensified, thus offering new possibilities of constructions and hybridization of the of the most different possible types. Experiment ―Profanações_superfície de eventos de construção coletiva‖, idealized by Phila7 is inserted in this perspective. Object of the discussion of such research, the experiment works with possible poetics arising from the intersection with the digital technologies, aiming at identifying and problematizing the challenges from the technological evolution and expansion in a scenic context

Novo sistema de aplicação de drogas em cirurgias oftalmológicas

The topical corneal application of antimitotic mitomycin-C (MMC) during refractive surgery is still characterized by a lack of standardization and considerable empirism. For this reason the creation of a system capable of reliable drug delivery represents a beneficial innovation for patients submitted to these procedures. Objective: Elaborate a new MMC delivery system during the transoperatory period of photorefractive keratectomy (PRK) followed by patent application. Methods: The project consists of an in vitro experimental study to create an MMC (0.02%) release system. The drug was impregnated in sterile Whatman® 41 paper filter discs with a diameter of 8 mm. After drying, the discs were applied to antibiogram plates seeded with Staphylococcus epidermidis (American Type Culture Collection ATCC 12228), followed by the addition of a drop of sterile water. At the end of 1 minute, the discs were removed and the plates incubated for 48 hours at 35oC. Mean drop volume in the collyrium flasks was measured using analytical balance weighing. The inhibition halo (mm) was correlated with the MMC impregnated into the disc. After completion of the invention design a patent application was lodged at the National Institute of Industrial Property. Results: The correspondence between MMC-produced inhibition halos indicated that a dose of 16μg was ideal for impregnating into the discs. The mean drop volume obtained from the collyrium flasks was 37.7 μL. A minute after the application of one drop of balanced saline solution, the system released an adequate concentration for PRK surgery. Conclusion: A new MMC delivery system was created for transoperatory application in photorefractive keratectomy (PRK). Publication of the patent application (number PI 0704739-8) gives the authors exclusive intellectual property rights. The study was sponsored by Ophthalmos Indústria e Comércio de Produtos Farmacêuticos S.A. (São Paulo-SP, Brazil) and received the indispensable scientific contribution of researchers from the fields of Pharmacy, Medicine, Biology, Statistics and Law, characterizing the work as multidisciplinary, in accordance with norms established by the Postgraduate Health Sciences Program of the Federal University of Rio Grande do Norte (UFRN)

O tempo das brincadeiras : memória, turismo e tradição em Barra do Camaratuba PB

Barra do Camaratuba belongs to Mataraca city, nearby the boarder between Paraíba and Rio Grande do Norte states. It was the chosen community to develop this research, objectifying to study the set of practical of the cultural manifestations and the implications of the local tourist activity, considering the cultural dynamics. We tried to reconstruct stories from the narratives of the oldest inhabitants, natives, among others that they had lived, some how, individual and collective experiences related to the popular tricks and the traditional parties, considering what they speak and imagine about their experiences and its culture. The Lapinha, the Pastoril, the viola s songs, the Balls of Concertina, the João Redondo, the Ox of Kings, the wheel of Coconut were common practical perceivable through the communitarian bonds. Among these manifestations, the only one that resisted for a longer time was the wheel coconut. The São Pedro s fest is another popular manifestation that appears on the current scene like the padroeiro party, while others cultural practical compose the spectacle s scenery. These questions cover many of the narratives of the interviewed ones in the interlaced thing between memory, tourism and tradition. Therefore, we tried to build our research from the memory, participant observation, orality, techniques of the life history, personal depositions, among others basic methods for the reconstruction of a collective memory . Speaking about the past of Barra do Camaratuba is to live again the parties, the blood relations, the terço , the work in the roçados , in the flour house, the fishing, the leisure and the habits of the daily life. In this community, there is the presence of conflicts of social and cultural order, caused for the hegemonic classes that sponsor the parties. In the padroeiro party we perceive that the mercantile logic has started, very recently, to transform the religious factor into an excuse to put into motion the local economy. This way, a community originated from artisan fishers and agriculturists, having the fishing practical as a way of subsistence and the tricks as a reference, they had started to compose a new social picture with the arrival of the others and with the presumption and recent tourist development. We perceive social, environmental and cultural impact transformations, exemplified by a non planned activity or a predatory tourism. The changes will always be pointed and compared with other passing in a sphere of relations lived by the natives, local players and fishers

A participação dos sujeitos e a reflexão coletiva das práticas na formação docente

Cet article propose, à partir d'une analyse de trois expériences différentes de la formation des enseignants, voir la pratique de l'enseignant comme une réalité et la comprendre, dans cette perspective, dynamique, génératrice de contenu et possible d être transformée. Une étude menée par un groupe de chercheurs de Sao Paulo do Potengi / RN avec des enseignants des écoles municipales dans les années 70, la mise en oeuvre du projet de réorientation curriculaire par le Bureau d Éducation de la ville de São Paulo - SP en 1989, et le cours Pédagogie de la Terre à l UFRN créée en 2002 sont pris en compte dans ce travail, comme des références dans la formation des enseignants qui démontrent à la fois les référentiel théorique et les actions développées sur la pertinence des réflexions par rapport à l'enseignement pratique comme point de départ quand on cherche à transformer l'école. Du matériel de lecture sur la manière dont ces processus de formation des événements a été possible de détecter la présence de deux éléments qui semblent être importants: la participation des personnes concernées et le reflet de leurs pratiques. Nous avons cherché à comprendre comment ces éléments apparaissent dans la pratique de deux étudiants du cours de Pédagogie de la Terre au cours de leurs classes de stage, en cherchant à identifier la façon dont ils font avancer ce point de vue de ce qui se passe dans le processus de formation. L'étude fait remarquer que la participation des sujets comme la réflexion collective des pratiques peuvent être cruciale pour la compréhension d'un enseignement qui peut être dynamique et de transformation des sujets, et qu elle peut se passer dans un processus de construction collective du savoir marquée par une refléxion et d une manière critique de faire et réflexive d'elle-même dans l'autonomie scolaire, améliorer la qualité de l'enseignement et le renforcement de l'enseignant et de l'élève comme des sujets actifs dans la reconstruction de leurs connaissances

Guiando almas femininas: a educação protestante da mulher em impressos confessionais no Brasil e em Portugal (1890-1930)

This paper treats confessional printings as a non formal space for the female education. It reflects on the importance of the woman s role to the diffusion of Protestantism in general, and its Presbyterian trend in particular, besides commenting on the proliferation of printings at the First Republic and its relation with education. In this study, Brazilian Northeastern is seen as a relevant space to the diffusion of Protestantism in Brazil; especially on what concerns the relations between Rio Grande do Norte and Pernambuco. Thereby some fountains were fundamental, as the confessional printings, that is, newspapers, magazines, prospects and other materials recollected in archives located in Natal/RN and Recife/PE, and São Paulo. It was also provided a brief incursion on Portuguese confessional printings kept in Oporto, PT. New Cultural History was chosen as theoretic-methodological guide, franchising ways inside the history of book and reading with the help of concepts like Interdependence, Social Configuration (ELIAS, 1993, 1994) and Representation (CHARTIER, 1990), considering that the survey worked out culture-manufactured products that is, intentional materials. It is well known that publishing, or better, the dissemination of printed material used to be associated to Protestants missionary practices since Reform began and, as what concerns the investigated period, in Portuguese and Brazilian lands indistinctly. Printing material in general books, booklets, fragments, as well as the press itself played a central role in divulging reformed ideas, their social options and the means of being and intervening in the world. In this regard, the confessional printings established themselves as an educative, although non schooled, informal space, but, all considered, relevant, seen that they dialogue with another important demand of that social group: formal, literate education. Because it dealt with the diffusion of a printed culture supported by the written word, it required of that group a different modus operandi: formal education. The first letters schools at first, then the high schools later represented spaces established for the circulation of printing material in order that they should be read, divulged and comprehended. This survey intends at last to take a look at Protestantism which, in this context of self-affirmation, reserved a specific place to woman by working out a non formal educational proposal disseminated by printing material. Three models were highlighted in the reformed proposal: Christian education in itself, household education, whose references of motherhood and care towards the neighbor were present and, at last, education to the public space, with emphasis on the practice of teaching. This study also offers a brief dialogue between Brazil and Portugal because, when some periodic printing, book or something like that got to be published in one margin of the Atlantic Ocean, the other margin surely was affected by that feat, received it, divulged it, corroborating the argument in support of the circulation of these printings. It was not only the same language that survived in both maritime coasts; some protestant specificities also crossed out along that sea

Estrutura genética de Chromis multilineata (Guichenot, 1853) (Perciformes Pomacentridae) na costa NE do Brasil e ilhas oceânicas: evidências de um passado evolutivo instável.

The fauna of Brazilian reef fishes comprises approximately 320 species distributed along the coast of the mainland and islands ocean. Little is known about the levels of connectivity between their populations, but has been given the interest in the relations between the offshore and the islands of the Brazil, in a biogeographical perspective. The oceanic islands Brazilian hosting a considerable number of endemic species, which are locally abundant, and divide a substantial portion of its reef fish fauna with the Western Atlantic. Among the richest families of reef fish in species are Pomacentridae. This study analyzed through analysis of sequences of the mitochondrial DNA control region (D-loop), the standards-breeding population of C. Multilineata in different areas of the NE coast of Brazil, involving both oceanic islands (Fernando de Noronha Archipelago and of St. Peter and St. Paul) and continental shelf (RN and BA). To this aim, partial sequences were used in the region HVR1 of mtDNA (312pb). The population structure and parameters for the estimates of genetic variability, molecular variance (AMOVA), estimation of the index for fixing (FST) and number of migrants were determined. The phylogenetic relationships between the populations were estimated using neighbor-joining (NJ) method. A group of Bayesian analysis was used to verify population structure, according to haplotype frequency of each individual. The genetic variability of populations was extremely high. The populations sampled show moderate genetic structure, with a higher degree of genetic divergence being observed for the sample of the Archipelago of St. Peter and St. Paul. At smaller geographical scale, the sample of Rio Grande do Norte and the Archipelago of Fernando de Noronha do not have genetic differentiation. Three moderately differentiated population groups were identified: a population group (I), formed by the Rio Grande do Norte (I') and the archipelago of Fernando de Noronha (I''), and two other different groups formed by the island population of the archipelago of Saint Peter and St. Paul (II) and Bahia (III). The genetic patterns found suggest that the species has suffered a relatively recent radiation favoring the absence of shared haplotypes. C. multilineata seems to constitute a relatively homogenous population along the West Atlantic coast, with evidence of a moderate population genetic structure in relation to the Archipelago of St. Peter and St. Paul. These data supports the importance of the dispersal larvae by marine current and the interpopulation similarity this species.

Diversificação cariotípica em cinco espécies de moréias do Atlântico Ocidental (Anguilliformes)

The Anguiliformes is constituted by 15 families, 141 sorts and 737 species. In this group eight families possess at least one karyotyped species, where a prevalence of karyotypes with 2n=38 is evidenced chromosomes and high NF, apparently basal for the Anguiliformes. The only family who shows a different karyotypic pattern from the others is the Muraenidae family. In this, of the eight species already described, all of them present 2n=42 chromosomes. Despite the dimension of this Order, few species present karyotypics descriptions. In the present work, a species of Ophichthidae, Myrichthys ocellatus (2n=38, 8m+14sm+10st+6a, NF=70) and three species of Muraenidae, Enchelycore nigricans (2n=42, 6m+8sm+12st+16a, NF=68), Gymnothorax miliaris (2n=42, 14m+18sm+10st, NF=84), Gymnothorax vicinus (2n=42, 8m+6sm+28a, NF=56) and Muraena pavonina (2n=42, 6m+4sm+32a, NF=52), collected in the coast of the Rio Grande do Norte state, Saint Peter and Paul Rocks and in the coast of Bahia state were analyzed. Mitotics chromosomes had been gotten through mitotic stimulation with yeasts. Among the analyzed species, it is observed the presence of characteristic large metacentric chromosomic pairs (≅10µm). As for the structural standard, heterochromatics regions in these species in centromeric position of the majority of the chromosomic pairs and simple ribosomal sites had been evidenced. For the Ophichthidae family, the gotten data corroborate the hypothesis of karyotypic diversification mediated by the occurrence of pericentrics inversions and robertsonians rearrangements, while in the Muraenidae, the identification of larger chromosomic values (2n=42), suggests derived karyotypes, possibly caused by possible chromosomic fissions

O comprometimento no trabalho e o significado do trabalho :um estudo com os funcionários do Banco do Nordeste do Brasil S/A

The current study analyses the relation between commitment (focusing on organization, career and syndicate) and the meaning of the work for 123 employees from a bank of mixed economy, crowed in agencies located in the Northeast capitals and also in four capitals out of this region: Belo Horizonte-MG, Brasília-DF, Rio de Janeiro-RJ and São Paulo-SP. It explores the commitment variability in the work of participants, as well as the score combination in foci, generating the commitment patterns, having used as an instrument a questionnaire consisting: a reduced version of OCQ Organizational Commitment Questionnaire (09 items), which measures the organizational commitment; the reduced Gordon s Scale (10 items), which measures the syndicate commitment; and the Blau s Scale, which measures the commitment to the career/occupation. It speculates, likewise, the meaning of work variability to the sample, seeking for the value attributes (what work should be), descriptive attributes (what work is) and its hierarchy, for which the ISMT-Inventário do Significado e Motivação no Trabalho has been applied; the work centrality, for which two specific inquires were used. The answers were registered in data at SPSS-Statically Package for Social for Windows, and from this point the statistical analyses were accomplished. Eight commitments to work patterns and six from the meaning of work were identified (Cluster analyses). The relation between both constructs was confirmed, corroborating other studies
