Coerção e ruptura estilísticas na poesia potiguar: a construção do ethos inventivo do poeta Jorge Fernandes

Within the poetic scenario of Rio Grande do Norte the publication of Livro de Poemas de Jorge Fernandes, in 2007, marks, in the imagery of the Potiguar community of poetry readers, producers and critics, the beginning of the social circulation of an inventive ethos associated with the poet Jorge Fernandes de Oliveira (1887-1953). Regarding the event mentioned earlier as a point of reference, this research investigates the construction of such ethos based on the counterpoint between the poet s individual stylistic choices and the stylistic options that prevailed in the lyric production of the Twenties in the 20th Century. The corpus comprises poetic texts (by the poet under discussion and by other poets who were, then, regarded as icons of the poetry of Rio Grande do Norte) and texts representative of local literary criticism (produced both during the Twenties and in other decades of the last century). Support to this analysis is grounded in Mikhail Bakhtin s theory of the utterance (mainly regarding style) and in Dominique Maingueneau s theory of the utterance (mainly regarding ethos). During the course of this investigation, the research has outlined an inventory of the prevailing individual stylistic choices of Jorge Fernandes de Oliveira and the reasons why such choices point out towards the inventive ethos associated with the poet.

Parahyba ou João Pessoa? Um estudo sobre a função social da História

Este trabalho é uma discussão sobre as funções sociais da História e da Memória. Para tanto, foi pensado diante do 80º aniversário da Revolução de 1930, marco da (re)fundação da capital paraibana, pois esta memória e a produção historiográfica a respeito do tema nos é bastante instigante. Falar de João Pessoa, seja da cidade, seja do indivíduo; no que se refere aos episódios de 1930, é tocar em um assunto bastante passional, onde chegar a um consenso é algo extremamente improvável. O objetivo deste trabalho é problematizar as funções sociais da História e suas utilizações, notadamente por meio do nosso objeto de estudo, buscando contribuir para a compreensão de como a memória e a escrita da História são frutos do trabalho constante das sociedades que as engendram. Estudar sobre a produção da memória e da historiografia bem como a função da escrita da História sobre esses episódios, entendendo-os como espaços específicos de disputas, notadamente sobre os embates de memórias nos últimos dez anos, trazendo novas reflexões sobre as funções sociais destas memórias

Turismo, território e políticas públicas: uma análise do destino João Pessoa/PB

This study presents an approach to tourism activity from the perspective of the territory, analyzing the importance of the roles of the State and public policies for tourism development. Tourism in the northeastern region of Brazil begins to take its rise from the late 1970 through public policies, whose goal was to provide the necessary conditions for tourism development. The tourism public policies were the key elements in the production process of tourist territories in the region. In the state of Paraíba, the public authorities elected the coastline as the main attraction and the state capital, João Pessoa, as the locus for the tourism development, with the city receiving a series of public policies. In this context, this research aims to analyze the development process of three specific public policies for tourism development in João Pessoa: The (mega)Projeto Costa do Sol (1988), the PRODETUR/PB I and II (1997 e 2005) and the Plano Estratégico de Desenvolvimento do Turismo na Paraíba, the Plano Amanhecer (2000). This study was guided by the question that even having been contemplated by the tourism public policies, João Pessoa still remains in a peripheral position in the regional tourism market. The methodological procedures for this study were literature and documents research and semi-structured interviews with tourism public officials and representatives from local tourism trade. The research came to prove that the discontinuity between governmental administrations hampered the implementation process of the tourism public policies studied. It was observed that the implementation of tourism public policies in the long term depends on the interaction between governments, as well as the collective political will to develop tourism in Joao Pessoa

Setor terciário e informalidade: algumas especificidades da (re)produção do espaço urbano de Bayeux-PB

This work has as study object the tertiary sector and (the re)production of the urban space of Bayeux-PB. For in such a way, one became necessary to the construction of a theoretical boarding that context the national reality, to be able itself to understand the reality local. This way to construct allowed an opening of the field of vision how much to the relevance of if ahead studying the tertiary sector and its weight of the current configuration of the society in a country as Brazil, e especially in a city of a State northeastern, as it is the case of Bayeux. The theoretical boarding had as base the two circuits of the urban economy, the productive reorganization and the transformations in the world of the work, as well as, the space organization and the distinction between the economic and social space of the tertiary activities, from the logic of functioning of the establishments: the regulation. Besides working with referring official data to the tertiary sector, the empirical study it had as reference one hundred and sixty and establishments tertiary, located in four axles of circulation of the city of Bayeux - PB, which are: Av. Liberdade, Av. Engenheiro de Carvalho, Av. Francisco Marques da Fonseca and Av. Marechal Rondon, that they had appeared in such a way stimulated for the processes of urbanization and industrialization lived deeply from years 70 in the "Great João Pessoa" how much, in the countries of the underdeveloped capitalist world, as Brazil. Being thus, the objective of the work was to study the tertiary sector and its relation with (the re)production of the urban space, standing out the functioning logic

Isoenzimas no monitoramento da deterioração de sementes de Euterpe espiritosantensis Fernandes

Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)

Tolerância à dessecação de sementes de palmito-vermelho (Euterpe espiritosantensis Fernandes)

Com o objetivo de identificar a tolerância à dessecação de sementes de Euterpe espiritosantensis, dois lotes de frutos foram colhidos na coleção de palmeiras do Instituto Agronômico de Campinas, no município de Ubatuba, estado de São Paulo e transportados em embalagem impermeável até a Faculdade de Ciências Agronômicas/UNESP, município de Botucatu, estado de São Paulo, onde foram despolpados. As sementes foram submetidas à secagem em sílica gel a partir das testemunhas não desidratadas (51,4% e 46,6% de teor de água), retirando-se amostras a cada 12 ou 24 horas. O efeito da desidratação foi avaliado através da porcentagem de germinação, e da velocidade de protrusão de embrião, do botão germinativo, da plúmula, e do comprimento das plântulas. Avaliaram-se ainda a matéria seca e o teor de água das sementes. Concluiu-se que as sementes de E. espiritosantensis são recalcitrantes, apresentando porcentagem alta de germinação (90,0% a 87,5%) quando não desidratadas (teor inicial de água de 51,4% a 46,6%). Abaixo de uma faixa de teor de água situada entre 40,7% e 51,4 % os valores de germinação e vigor foram significativamente reduzidos. A mortalidade total das sementes foi observada, com a redução do teor de água das sementes a uma faixa situada entre 13,4% e 15,8%.

Desempenho de bovinos jovens das raças Aberdeen Angus e Hereford, confinados e alimentados com dois níveis de energia

Estudou-se o desempenho de bovinos machos não-castrados das raças Aberdeen Angus (AA) e Hereford (HE) em confinamento, submetidos a dois níveis de energia, em esquema fatorial 2 x 2, sendo o menor nível com 3,07 e o maior com 3,18 Mcal/kg de energia digestível (12 e 32% de concentrado na dieta, respectivamente). Foram utilizados oito animais da raça AA e oito HE, com idade inicial de nove meses e peso médio inicial de 220,31 kg, que permaneceram confinados até que o peso da carcaça atingiu o mínimo de 190 kg (estimativa). Os animais da raça AA apresentaram maior consumo de MS, em % PV (2,27 vs 2,10%) e em g/kg0,75 (91,4 vs 86,4 g). Os animais que consumiram o maior nível de energia na dieta apresentaram maiores consumos de MS/dia (6,31 vs 5,71 kg), em PV (2,26 vs 2,11%) e em g/kg0,75 (92,28 vs 85,44 g), de energia digestível (ED), em Mcal/dia (20,58 vs 18,13 Mcal), e de PB, em kg/dia (0,845 vs 0,759 kg), além de maior ganho médio diário de peso (1,409 vs 1,250 kg). Os animais que consumiram o menor nível apresentaram maiores consumos de fibra em detergente neutro (FDN), em kg/dia (2,23 vs 2,07 kg), e de fibra em detergente ácido (FDA), em kg/dia (1,13 vs 1,01 kg). Os consumos de MS/dia, de FDN e de FDA, nos animais que consumiram o menor nível de energia, tiveram comportamento linear e, naqueles que receberam o maior nível, comportamento quadrático, frente aos períodos de confinamento. Para as características consumo de MS, em %PV e em g/kg0,75, nos tratamentos com menor nível de energia, o comportamento foi de forma cúbica e naqueles de maior nível, de forma quadrática. O consumo de ED apresentou, nos períodos, comportamento linear para o menor nível energético e cúbico para o maior nível.

Toxicity of synthetic piperonyl compounds to leaf-cutting ants and their symbiotic fungus

The development of Leucoagaricus gongylophorus, the fungus cultured by the leaf-cutting ant Atta sexdens was inhibited in vitro by synthetic compounds containing the piperonyl group. In addition, worker ants that were fed daily on an artificial diet to which these compounds were added had a higher mortality rate than the controls. The inhibition of the fungal growth increased with the size of the carbon side chain ranging from C1 through C8 and decreasing thereafter. 1-(3,4-Methylenedioxybenzyloxy)octane (compound 5) was the most active compound and inhibited the fungal development by 80% at a concentration of 15 μg m1-1. With worker ants the toxic effects started with compound 5 and increased with the number of carbons in the side chain. Thus, for the same concentration (100 μg m1-1) the mortality rates observed after 8 days of diet ingestion were 82%, 66% and 42%, for 1-(3,4-methylenedioxybenzyloxy)decane, 1-(3,4-methylenedioxybenzyloxy)dodecane and compound 5, respectively, whereas with commercial piperonyl butoxide the mortality was 68%. The latter compound, which is known as a synergist insecticide, was as inhibitory to the symbiotic fungus as the synthetic compound 5. The possibility of controlling these insects in the future using compounds that can target simultaneously both organisms is discussed. © 2001 Society of Chemical Industry.

Inhibition of the symbiotic fungus of leaf-cutting ants by coumarins

Leaf-cutting ants are known to be a serious pest for agriculture due to the high amounts of vegetal matter from crops used by them in order to cultivate a symbiotic fungus on which they rely for food and enzymes. The mutualism between the fungus and the ants is a point to be explored when alternative methods of control are being thought of. Considering that some plants are naturally resistant to phytophagous insects, some natural products (secondary metabolites) should be evaluated with respect to their insecticide and/or fungicide properties. In this paper we isolated eight coumarins from four different plant species and we determined their effect on the development of the symbiotic fungus of the leaf-cutting ant Atta sexdens. With the exception of clausarin, all the other coumarins were inhibitory from 64 μg mL-1 through 80 μg mL-1 and xanthyletin inhibited the fungus at 25 μ mL -1. ©2005 Sociedade Brasileira de Química.

Toxicity of Cipadessa fruticosa to the leaf-cutting ants Atta sexdens rubropilosa (Hymenoptera: Formicidae) and their symbiotic fungus

Crude extracts from fruits, branches and leaves of Cipadessa fruticosa were assayed on Atta sexdens rubropilosa workers and their symbiotic fungus Leucoagaricus gongylophorus. The results showed that the majority of the extract tested reduced significantly (p < 0.05) the survival of the workers comparable to the neem oil. In addition, the dichloromethane extract from fruits and the hexane extract from branches of C. fruticosa inhibited in 80% the development of the symbiotic fungus. The hexane and dichloromethane extracts from fruits of C. fruticosa were fractionated and their fractions were subjected to new bioassays. Several fractions showed relevant activity on ants, but none of them inhibited significantly the fungal growth. The possibility of controlling leaf-cutting ants in the future using C. fruticosa is discussed.

Limonoids from Cipadessa fruticosa and Cedrela fissilis and their insecticidal activity

The chemical investigation of the fruits of Cipadessa fruticosa (Meliaceae) afforded the new limonoid cipadesin B and the known swietemahonolide. From the roots of Cedrela fissilis (Meliaceae) were isolated the limonoid 3β-acetoxycarapin, new as natural product, along with the triterpenes oleanolic and oleanonic acid. These compounds and other six mexicanolide limonoids previously isolated from C. fruticosa showed insecticidal activity against the leaf-cutting ants Atta sexdens rubropilosa. ©2005 Sociedade Brasileira de Química.

Limonoids from andiroba oil and Cedrela fissilis and their insecticidal activity

Nine limonoids were isolated from Carapa guianensis and Cedrela fissilis. Among them, 1,2-dihydro-3β-hydroxy-7-deacetoxy-7-oxogedunin is a new compound. Moreover, the assignments of some chemical shifts of xyloccensin k have been corrected and 1H NMR data of 7-deacetylgedunin have been assigned for the first time. These isolated limonoids were assayed on Atta sexdens rubropilosa workers showing moderate insecticidal activities. ©2006 Sociedade Brasileira de Química.

Maxillary Rehabilitation Using Fixed and Removable Partial Dentures with Attachments: A Clinical Report

Despite requiring dental crown preparation and possible root canal treatment, besides the difficulty of clinical and laboratory repairs, and financial burden, the association between fixed (FPD) and removable partial dentures (RPD) by means of attachments is an important alternative for oral rehabilitation, particularly when the use of dental implants and FPDs is limited or not indicated. Among the advantages of attachment-retained RPDs are the improvements in esthetics and biomechanics, as well as correction of the buccal arrangement of anterior teeth in Kennedy Class III partially edentulous arches. This article describes the treatment sequence and technique for the use of attachments in therapy combining FPD/RPD. © 2013 by the American College of Prosthodontists.
