This work is an ethnographic research with collectors women of Mangaba in the village of Ponta Negra in Natal - RN. This Women also known as Mangabeira's women reproduce a practice learned with their ancestors, collecting this fruit in the coastal tablelands forests and latter commercializing it in the local markets. This research uses the methodology of oral history and visual anthropology with presentation of collected images on board. It is intended to emphasize the botanical and environmental aspects of the Mangabeira plant, its ecosystem, territorial, economic and historical aspects of it, also the knowledge of this extractive practice of our immaterial culture.

The theater of puppets is one of the many expressions of popular culture which is marked by ongoing constructions and transformations in its symbolic representations as well as its characters and performances. In the city of Natal/RN, there is a manipulator called Heraldo Lins, an artist who operates such puppets, and has been performing his puppet since 1992. Lins has his own look at how he produces his performances and seeks to adjust his puppets to social and rentable contexts. Lins‟s performances are tailor-made in accordance with the request of his customers, as he makes up the passages and lines of his puppets according to his audience. This research aimed to study how the Heraldo Lins Mamulengos Show is built, especially its changes. We note that Lins chooses to dismantle the symbolic values of the tradition in the regular puppet theater once he adapts to modern patterns, placing himself between the traditional puppet theater and the cultural industry. The work in camp was made through a methodological focused in a participative observation and an audiovisual registry

The incidence of toxic cyanobacterial blooms is one of the important consequences of eutrophication in aquatic ecosystems. It is a very common phenomenon in reservoirs and shrimp ponds in the State of Rio Grande do Norte (RN), Brazil. Cyanobacterias produce toxins which can affect aquatic organisms and men trough the food chain. Aiming to contribute to the studies of cyanobacterias in RN, we propose: a) to evaluate the toxicity of isolated cyanobacterias in important fresh-water environments; and b) to verify the effects of both natural and cultured blooms occurred in reservoirs for human supply and in the cladoceran Ceriodaphnia silvestrii. This study was carried out using samples of natural blooms occurred between March and October of 2004 in Gargalheiras Dam (08º L e 39º W), in July of 2004 in Armando Ribeiro Gonçalves Dam (06o S e 37o W) and in commercial shrimp ponds (Litopenaeus vannamei) located in fresh-water environments. The samples were collected with plankton net (20µm.) for identification, isolation and obtaining of phytoplanktonic biomass for liophilization and later toxicity bioassays. The toxicity of cultured samples and natural blooms was investigated through bioassays in Swiss mice. Quantification of cyanobacteria in samples was conducted following the Ütermol method, with 300mL samples fixed with lugol. The toxicity test with Ceriodaphnia silvestrii followed ABNT, 2001 recommendations, and were accomplished with natural hepatotoxic bloom s samples and cultured samples of both non-toxic and neurotoxic C. raciborskii. In this test, five newborns, aged between 6 and 24 hours, were exposed to different concentrations (0 a 800 mg.L-1) of crude cyanobacterial extracts during 24 and 48 hours. Three replicates were used per treatment. The pH, temperature and dissolved oxygen at the beginning and after 24 and 48hours from the test were measured. We estimated the CL50 through the Trimmed Spearman-Karber method. The blooms were constituted by Microcystis panniformis, M. aeruginosa, Anabaena circinalis, Cylindrospermopsis raciborskii and Planktothrix agardhii, producers of mycrocistin-LR confirmed with HPLC analysis. Samples of hepatotoxic blooms registered toxinogenic potential for C. silvestrii, with CL50-24h value of 47.48 mg.L-1 and CL5048h of 38.15 mg.L-1 for GARG samples in march/2005; CL50-24h of 113,13 mg.L-1 and CL5048h of 88,24 mg.L-1 for ARG July/2004; CL50-24h of 300.39 mg.L-1 and CL50-48h of 149.89 mg.L-1 for GARG October/2005. For cultured samples, values of CL50-24h and CL50-48h for C. raciborskii toxic strains were 228.05 and 120.28 mg.L-1, respectively. There was no mortality of C. silvestrii during the tests with non-toxic C. raciborskii strain. The toxicity test with C. silvestrii presented good sensitivity degree to cyanotoxins. The toxicity of natural hepatotoxic blooms samples (microcystins) and cultured neurotoxic saxitoxins producer samples analyzed in this study give us strong indications of that toxin s influence on the zooplanktonic community structure in tropical aquatic environments. Eleven cyanobacteria strains were isolated, representing 6 species: Anabaenopsis sp., Cylindrospermopsis raciborskii, Chroococcus sp., Microcystis panniformis, Geitlerinema unigranulatum e Planktothrix agardhii. None presented toxicity in Swiss mice. The strains were catalogued and deposited in the Laboratório de Ecologia e Toxicologia de Organismos Aquáticos (LETMA), in UFRN, and will be utilized in ecotoxicológical and ecophysiological studies, aiming to clarify the causes and control of cyanobacterial blooms in aquatic environments in RN. This state s reservoirs must receive broader attention from the authorities, considering the constant blooms occurring in waters used for human consumption

Innumerable studies have focused been reported on the sleep spindles (SS), Sharp Vertex Waves (SVW) and REM, NREM Sleep as indicators interpreting EEG patterns in children. However, Frequency and Amplitud Gradient (FAG) is rarely cited sleep parameter in children,that occurs during NREM Sleep. It was first described by Slater and Torres, in 1979, but has not been routinely evaluated in EEG reports. The aim of this study was to assess the absence of SS, SVW and FAG, as an indication of neurological compromise in children. The sample consisted of 1014 EEGs of children referred to the Clinical Neurophysiology Laboratory, Hospital Universitário de Brasília (HUB), from January 1997 to March 2003, with ages ranging from 3 months to 12 years old, obtained in spontaneous sleep or induced by choral hydrate. The study was transversal and analytical, in which, visual analysis of EEG traces was perfumed individually and independently by two electroencephalographers without prior knowledge of the EEG study or neurological findings. After EEG selection, the investigators analyzed the medical reports in order to define and correlate neurological pattern was classified according to the presence or absence of neurological compromise, as Normal Neurological Pattern (NNP), and Altered Neurological Pattern (ANP) respectively. From the visual analysis of the EEG(s), it was possible to characterize 6 parameters: 1- FAG present (64,1%); 2- FAG absent (35,9%); 3 - normal SS (87,9%); 4 - altered SS s (12,1%); 5 - normal SVW s (95,7%); 6 - altered SVW s (4,3%). The prevalence of well-formed FAG is found in the 3 months to 5 years age group in the children with NNF. FAG was totally absent from the age of 10 years. When comparing the three sleep graphielements, it was observed that SVW and SS were predominant in children with NNF. However, FAG absent was more prevalent in the ANF than in altered SS an SVW. The statistical analysis showed that there is a strong association of FAG absent, with isolated alteration, in ANF patients, in that the prevalence ratio was 6,60. The association becomes stronger when FAG absent + altered SS(s) is considered (RP= 6,68). Chi-square test, corrected by Yates technique, showed a highly significant relation for FAG ρ= 0,00000001, for error X of 5%, or else the 95% confidence interval (ρ<0,05). Thus, the FAG absent were more expressive in ANF patient than altered SS(s) and SVW(s). The association becomes stronger in order to establish a prognostic relation, when the FAG is combined with the SS. The results os this study allow us to affirm that the FAG, when absent at ages ranging from 3 months to 5 years , is an indication of neurological compromise. FAG is an age-dependent EEG parameter and incorporated systematically, in the interpretation criteria of the EEG of children s sleep, not only in the maturational point of view, but also neurological disturbances with encephalic compromise

O artigo analisa as atuais políticas culturais e analisa empiricamente as ações da unidade paulistana do Centro Cultural Banco do Brasil (CCBB). O objetivo é interpretar como esta instituição opera o fomento à cultura no contexto da normatização cultural no Brasil. A articulação institucional entre Banco do Brasil e seu Centro Cultural enseja algumas particularidades no campo da difusão cultural, pois o status institucional do CCBB condiciona de maneira decisiva as formas como transcorrem as relações com produtores culturais, público consumidor e com seu respectivo mantenedor. Trata-se de estudo baseado em pesquisa bibliográfica, levantamento de campo e na abordagem dialética de análise. Conclui-se que, ao consentir um laissez-faire cultural, o Estado admite que o mercado imponha sua lógica à cultura, de modo que o objeto empírico pode ser caracterizado como um exemplo dessa dinâmica.

O objetivo deste estudo foi avaliar a possibilidade de agrupar talhões de cana-de-açúcar colhida mecanicamente e sem queima prévia da palha na região de Ribeirão Preto-SP, de acordo com o potencial de infestação de plantas daninhas, por meio de análise de agrupamento por método hierárquico e outras técnicas de análise multivariada, utilizando como variável o índice de infestação relativa atribuído por avaliações visuais, em duas etapas. A primeira contemplou 20 talhões de cana-planta com ciclo de 18 meses; essas áreas foram utilizadas para comparação de dois métodos de estimativa da composição específica da flora daninha: análise fitossociológica e por meio da porcentagem visual de cobertura geral (CG) e específica (CE). A segunda etapa consistiu no levantamento da composição específica da comunidade de plantas daninhas em 189 talhões, em áreas de cana-soca colhidas durante a safra de 2008, incluindo nesses talhões apenas CG e CE. Com as informações sobre os levantamentos da comunidade infestante foi construído um banco de dados, posteriormente submetido a análises exploratórias por técnicas de estatística multivariada. Para as principais espécies dentro dos talhões, que foram DIGNU, ARACH, IPOHF, MRRCI e IPOQU, seguidas de CYPRO, ELEIN e EPHHS, foram verificados 75% de coincidências de resultados entre os dois métodos de avaliação. Também notou-se que as avaliações visuais de porcentagem de cobertura das espécies podem substituir, para fins de praticidade, agilidade e aplicabilidade, as avaliações fitossociológicas, uma vez que proporcionaram boa capacidade de detecção das principais plantas daninhas dentro de cada talhão. As técnicas de estatística multivariada demonstraram que os talhões podem ser agrupados de acordo com semelhanças na intensidade da infestação e na composição específica.

The subject of this research is the spiritual religious field, connected with the local cultural perspectives. Its basis is the analysis of two spiritual groups settled in Natal/RN: The Spiritual Group Evangelho no Lar and the Spiritual Center Garimpeiros da Luz . These two groups represent a point of convergence of several sectors of this religion, either through its insertion in the local sphere or in contact to nationally influent leaders, like the mediums Francisco Cândido Xavier and Divaldo Pereira Franco. Then, it aims to reach the potiguar singularities in their spiritualism approaches, looking for an analyses to possible connections between local values and themes from the spiritualism largely developed in Brazil. So, its objective is to act in the scope of influence, references, representations and adaptive practices in a local context, and they signalize special practices . The approaches until now developed refer only to the living of a Brazilian spiritualism, perfectly developed in contact with the catholic substrate, but there s still a gap about the local observation, with its peculiarities, which its research aims to disclosure. The option for a qualitative approach, in perfect relationship with the nature of the questions which were made was considered as an appropriate way to guide the study. To reach this, it will be made an ethnography of the studied groups, not only in the use of open interviews with its members but also in the contact and observation of its religious behavior, for example: meeting for studies of the doctrine, mediunic meetings, public lectures, helping the public in general. As results of this research we can point to the delimitation of local cultural references, which are undeniable, in relation to the identification of RN personalities who are considered coordinators or active spirits in the work performed by the groups. Thus, Auta de Souza, poetess and woman of great religiosity, Augusto Severo de Albuquerque Maranhão, martyr of the aeronautics, Father João Maria, object of popular devotion and Abdias Antônio de Oliveira, ex president of the Spiritual Federation of RN, present themselves as spiritual beings who lead the adaptability to the local context. In such a context, we have to point out the work of mediums, who, having a specific charisma, interacted with the groups in the establishment of these cultural bridges already made in their own contexts (national level), through the work equally possible to be locally reproduced. This and other facts, point out to perspectives of cultural circularity , including referring to a greater linking to sub layers in a true zone that converges and has circulation between an erudite spiritualism with another one, turned to the incorporation of local and popular elements

The current dissertation has as its main object of study the malaise with politics phenomenon. To comprehend it, is carried out in this work a inquiry, in different stages of analysis, based in the empirical data raised by the research Os Processos Sociais de Recepção do Horário Gratuito de Propaganda Eleitoral , made by the Grupo de Estudos Mídia e Poder, of the Universidade Federal do Rio Grande do Norte, during the local elections of 2004 in the city of Natal. Based in the focus group technique, such research raised an ample set of information about the decoding process of the electoral television programs, made by six different groups of citizens from the popular classes. Beginning from the presuppose which such process is influenced by the representations about politics made by those subjects, we use that set of empirical information to inquiry not only the decoding, but that same representations which this process is based. In this way, we analyse, in one side, the globally contrary decoding which subjects made from a conforming code of opposition and, in the other, the structure of feeling which it s based, called structure of feeling of the malaise with politics. Such structure is compound by generating themes which expresses the contraposition about the institutionalized politics and, in the same time, a resignation about politics which fortifies the dominant groups hegemony. We support the thesis which this set of representations about politics is caused by the denial of rights frame which those subjects are immersed

La imagen fotográfica la imagen despierta pulsiones, en una experiencia provocativa que acciona el campo mítico-fenomenológico descíframe o te devoro . El texto fotográfico no constituye sólo un momento del real , es mucho más que un recorte gélido del tiempo pasado. Sobretodo, porque la comprensión del lenguaje subyacente a la imagen fotográfica se coloca dentro y más allá de lo meramente dado y/o objetivado . En la comprensión de la imagen se disponen regímenes de subjetivación horadado por códigos culturales, dominios del lenguaje, símbolos, experiencias estéticas, creación simbólica, valores, memorias, imaginarios. En ese sentido, surge el estudio, el levantamiento y la sistematización del acervo fotográfico dejado por el fotógrafo autodidacta: Enoque Pereira das Neves (1918-2002), que produjo formas visuales reveladoras de orientaciones culturales colectivas y universos fotográficos imaginarios. Él fotografió por medio siglo la vida cotidiana del campesino, en tierras potiguares y paraibanas. En la comprensión del acervo opte por subdividirlo en álbumes los cuales revelan las intimidades del fotógrafo con el lugar, una escrita de si, un estado del alma, del sujeto que observa la relación sociedad y naturaleza, en una especie de simbiosis en que accionan potencias resonantes de creación en el devaneo de la materia, sobresaliéndose a la pulsión terrestre, o enraizamiento, os rizomas del hombre unido a la tierra, las tradiciones, a rusticidad, laboral, bien como el apelo estético direccionado al agua: pulsión de vida en tierras áridas. La comprensión del inmenso acervo, evaluado en más de cincuenta mil fotografías es profundamente representativa de predilección temática circunstanciada por la niñez, la narrativa enfoca imágenes míticas como la del Eros nudo, la madona y el niño, y prácticas culturales del universo infantil, como el juguete y el juego. Mismo el acervo siendo un apelo estético a la vida surgió la imagen fotográfica de la muerte, especialmente, la muerte en la niñez o ángel y la muerte de ancianos como o deseo de la última imagen de aquel entre los suyos. La investigación es transversal por los siguientes objetivos: propongo un reconocimiento del acervo de Enoque Pereira das Neves en la intención de comprender el universo imaginario presente en su obra fotográfica. Invisto también, en la posibilidad de hacer la lectura del acervo como álbum imaginario.

Objetivou-se estudar o efeito de herbicidas aplicados em pré e pós-emergência, isolados e em combinações nas épocas seca e úmida, para o controle de leiteiro (Euphorbia heterophylla) na cultura de cana-de-açúcar. O experimento foi desenvolvido no período de agosto de 2008 a junho de 2009, em área de produção comercial de cana-de-açúcar localizada no município de Jaboticabal-SP. O delineamento experimental foi o de blocos ao acaso, com quatro repetições, em esquema de parcela subdividida. Na época seca foram avaliados os herbicidas amicarbazone (1.400 g ha-1), imazapic (147 g ha-1) e sulfentrazone (900 g ha-1), aplicados em 1º/8/2008 após a colheita da cana, e testemunha sem manejo prévio das plantas daninhas. Os herbicidas utilizados na época úmida foram: mesotrione isolado (192 g ha-1) e em mistura (120 g ha-1) com ametryn (1.500 gha-1), atrazine (1.500 gha-1) ou diuron + hexazinone (702 + 198 g ha-1), aplicados em 14/11/2008, além de testemunha capinada e outra sem manejo das plantas daninhas. A aplicação de imazapic na época seca foi eficaz no controle de E. heterophylla, dispensando a complementação de manejo na época úmida. No entanto, para os herbicidas amicarbazone e sulfentrazone houve necessidade da aplicação de mesotrione, isolado ou em mistura com ametryn, atrazine ou diuron + hexazinone, para a manutenção do controle de E. heterophylla na época úmida (de 105 a 230 dias após a aplicação na época seca). Quando não foi realizada a aplicação de herbicida na época seca, constatou-se melhor controle de E. heterophylla na época úmida com o herbicida mesotrione associado a ametryn, atrazine ou diuron + hexazinone do que quando aplicado isoladamente. Apesar dos sintomas visuais de fitointoxicação ocasionados pelos tratamentos mesotrione + ametryn e mesotrione + (diuron + hexazinone) pulverizados na época úmida, nenhum dos manejos adotados ou combinações entre eles interferiu no número de colmos viáveis por metro linear, no diâmetro e na altura de colmos de cana-de-açúcar.

A parreira-brava (Cissampelos glaberrima) e a erva-palha (Blainvillea romboidea) estão no início de sua dispersão na cultura da cana-de-açúcar no Estado de São Paulo e são espécies de extrema agressividade e de difícil controle. Objetivou-se neste trabalho estudar a eficácia dos herbicidas trifloxysulfuron-sodium + ametryne, picloram + 2,4-D, 2,4-D e fluroxypyr, aplicados em pós-emergência, no controle de parreira-brava e ervapalha em canaviais. O delineamento experimental utilizado foi o de blocos casualizados, com seis tratamentos e quatro repetições. Foram feitas avaliações visuais das porcentagens de controle, aos 7, 14, 21, 29, 36, 42, 56 e 90 dias após a aplicação (DAA) dos herbicidas. Medidas das alturas das plantas de cana-de-açúcar foram feitas aos 29 e 56 DAA, e a contagem do número de afilhos foi feita aos 33 DAA. Na colheita, fez-se a contagem do número de colmos, e a produção foi calculada através da pesagem dos colmos da parcela. Diante dos resultados obtidos, pode-se concluir que o trifloxysulfuron-sodium + ametryne (1.500 g ha-1) agiu rápida e eficientemente na parte aérea das plantas adultas de parreirabrava, porém não impediu que as brotações surgissem após os 42 dias da aplicação. No entanto, o picloram + 2,4-D (a 2.040 g ha-1) e o fluroxypyr (345 g ha-1) mantiveram níveis de controle da parreira-brava superiores a 90%, até 90 DAA. O controle de erva-palha mostrouse não-satisfatório com a aplicação de trifloxysulfuron-sodium + ametryne e bastante eficaz (100%) com os demais herbicidas.
