Лирическая поэма Ивана Штрпки «Интермедии. Марионетки, укороченные на голову»: семантика заглавия и метафорика сюжета
Authors: Барковская Нина , Громинова Андреа
Published: January 2018

The present paper is aimed at the interpretation of Ivan Štrpka’s poem Interlude. Puppets Shortened by a Head. The ambiguity of main pictures, the logics of the plot and the functions of intertext as well as peculiarities of its poetics are analysed. The theatricalization of the artistic world shows the crisis of totalitarian society, a “mental Armageddon” as well as an increase in contradictions in the very lyric subject at the same time. The social and politic meaning in the poem is directly related to philosophic content and metaliterature thoughts. The traditions of surrealism and dadaism are important to the author, and we can make a parallel with “neobaroque” of Elena Shvarts in contemporary Russian literature.
The figurative basis of Russian dialectal words and expressions with the meaning of negative assessment of social changes
Authors: Leontyeva Tatyana
Published: January 2018

The paper presents the results of a study of metaphorical vocabulary with the meaning of assessment of social change. The analysis involves common Russian vocabulary as well as the material of Russian dialects. Previously unpublished expeditionary records of dialect speech are introduced into academic discussion. Special attention is paid to the onomasiological analysis of linguistic facts. Four groups of motives are revealed: the motives of destruction (loosening, turning inside out, and death); spatially dynamic motives (moving away and disappearance); the motives of qualitative changes (the loss of one’s own properties and status, the acquisition of similarity with representatives of a foreign nation, the acquisition of worse properties, cooling down); and the motives of confusion (mixing of different cultures and disorientation). It is shown that the bearers of traditional folk culture tend to evaluate the changes of any kind as undesirable. A disapproving assessment of social change is due to the orientation of traditional culture toward strict adherence to customs.

Published: January 2018

ABSTRACT Autoimmune encephalitis (AIE) is one of the most common causes of noninfectious encephalitis. It can be triggered by tumors, infections, or it may be cryptogenic. The neurological manifestations can be either acute or subacute and usually develop within six weeks. There are a variety of clinical manifestations including behavioral and psychiatric symptoms, autonomic disturbances, movement disorders, and seizures. We reviewed common forms of AIE and discuss their diagnostic approach and treatment.

Authors: Gagliardi Vivian Dias Baptista , Simis Marcel , Cabeça Hideraldo Luiz Souza , Gagliardi Rubens José
Published: January 2018

ABSTRACT Stroke is currently the second leading cause of death in Brazil. Neurologists’ reports on the absence of adequate resources for stroke care are frequent; however, there are no objective data on this perception. Objective To assess the perception of neurologists of stroke care conditions in Brazil. Methods Neurologists from all over Brazil were surveyed by means of an anonymous questionnaire about the main shortcomings in stroke care, focusing particularly on physical structure and infrastructure (diagnostic methods, patient transport, availability of beds, multi-professional team). Results The main shortcomings are indicated: the worst conditions, among all items surveyed, were found in the public sector. In the private sector, conditions were better. Conclusions Care conditions are worse in the public sector with regard to both infrastructure and human resources. Future public health policies for the prevention and treatment of stroke should be formulated, taking into consideration neurologists’ perceptions.

Authors: Campos Luiz Augusto , Feres Júnior João , Guarnieri Fernando
Published: January 2018

RESUMO O artigo traça o perfil autoral, disciplinar, bibliográfico e temático da revista DADOS por meio de uma análise bibliométrica de todos os textos publicados pelo periódico nos seus 50 anos de existência (1966-2015). A composição da base se deu pelo processamento dos textos indexados na plataforma SciELO e da leitura e codificação manual dos volumes mais antigos da revista. Diferentes técnicas para o estudo de corpora linguísticos foram utilizadas para delinear o perfil das bibliografias recorrentes, mormente a Análise de Correspondências Simples, e o perfil temático dos textos, sobretudo a Modelagem de Tópicos. Os resultados sugerem que a revista privilegiou artigos sobre as temáticas públicas prementes de cada momento histórico, aliando rigor metodológico ao compromisso com as questões públicas mais candentes no país e no mundo.
A Sociologia e a Sociologia Política em DADOS
Authors: Botelho André , Carvalho Lucas Correia
Published: January 2018

RESUMO O artigo identifica e discute alguns movimentos cognitivos cruciais da coleção Sociologia da revista DADOS. Inspirada em ideias sobre a dinâmica da diferenciação funcional da sociologia de Niklas Luhmann como uma chave geral de leitura dos dados da pesquisa, sugere o papel central que a sociologia política, especialidade mais recorrente, tem na coleção. Ela protagoniza um movimento simultâneo de diferenciação em relação ao conjunto dos artigos publicados e de modificação desse ambiente, pelas ressonâncias que vai imprimindo nas outras especialidades da sociologia. Nessa mesma chave, sugere o papel de autodescrição reflexiva em relação ao conjunto da coleção assumido pelo pensamento social e político, a segunda especialidade mais recorrente nesses 50 anos de publicação da revista.
A Difícil Institucionalização da Ciência Política Italiana: De Muratori a Mussolini
Authors: Bianchi Alvaro
Published: January 2018

RESUMO Embora existisse uma longa tradição nacional de pensamento político na Itália, a ciência política desse país enfrentou dificuldades para se institucionalizar. As primeiras tentativas datam do século XVIII, mas foi só na segunda metade do século XX que ela se transformou em uma disciplina autônoma. O presente artigo argumenta que a forte associação da ciência política com o processo de construção do Estado nacional italiano e com o ensino do direito foram as causas principais de sua lenta institucionalização. Metodologicamente, busca-se reconstruir uma história política da ciência política, ressaltando contextualmente o debate da época e restabelecendo a legislação pertinente à constituição de faculdades, escolas e cursos de ciência política.
Interdisciplinarity in French Social Sciences Scientific Journals
Authors: Brun Eric
Published: January 2018

ABSTRACT Taking France as its example, the following article examines the relations between the disciplines of social sciences discovered during the arduous task of classifying French social sciences journals according to more specific disciplines (sociology, political science and anthropology, etc.). Based on a study of the journals’ own methods of self-labeling and the methods used to classify these journals by a French assessment body (AERES), as well as the forming of journal executive committees, the article highlights the fact that the journals frequently cover a range of disciplines, without this implying the disappearance of disciplinary structures. In fact, the article instead reveals that the connections made by the journals between the various disciplines of social sciences are unlikely and disproportionately represented.
Fauna of mosquitoes (Diptera: Culicidae) in Goytacazes National Forest and surrounding area, State of Espírito Santo, Southeastern Brazil
Authors: Virgens Thieres Marassati das , Rezende Helder Ricas , Pinto Israel Souza , Falqueto Aloísio
Published: January 2018

Abstract Mosquitoes comprehend a group with a major impact on public health, because some species transmit parasites vertebrate hosts. Comparative studies between preserved environment and disturbed areas provide important epidemiological information, due to the major knowledge on species populational dynamics and the possibility of a contact between vector species and human population. This work aims to characterize and compare the fauna of mosquitoes in the Goytacazes National Forest (GNF) and surrounding area, in the State of Espírito Santo, in Brazil. Collections occurred simultaneously in a preserved environment and in a peridomicile, from 15:00 to 18:00, between July 2008 and May 2009. In each environment, it was used a modified trap of Shannon type. As a result, 1,490 specimens from 14 genera and 19 identified species were collected. The species diversity (H = 1.95), species richness (S = 17), equitability index (J = 0.68) and the number of collected specimens (n = 1,100) were higher in the forest environment. The plentiful species were respectively Aedes (Ochlerotatus) scapularis (Rondani, 1848), Culex (Culex) nigripalpus Theobald, 1901 and Aedes (Ochlerotatus) fulvus (Wiedemann, 1828). Our results demonstrate that the occurrence of vector species in this region increases the potential risk of diverse arboviruses occurrence, especially wild-type yellow fever.
Audiências públicas do Legislativo estadual: fatores endógenos e exógenos na análise da efetividade da participação
Authors: Zorzal Gabriela , Carlos Euzeneia
Published: January 2018

Resumo Este artigo trata das audiências públicas da Lei Orçamentária Anual (LOA) realizadas pela Assembleia Legislativa do Espírito Santo, no período de 2007 até 2014. O tema central é a efetividade da participação das audiências, ancorada em duas dimensões: o momento deliberativo e os resultados das audiências para o orçamento. Partimos do pressuposto que, apesar da dificuldade de mensurar efeitos práticos, instituições participativas, tais como as audiências da LOA, atuam para aprofundar a democracia, destinando recursos públicos de acordo com demandas da sociedade civil. O artigo analisa elementos constituintes das audiências (formato institucional, perfil dos legisladores, perfil dos participantes, relação Executivo-Legislativo e as emendas parlamentares) para avaliar a efetividade dessa participação. Utilizamos uma abordagem multimétodo com a combinação de três ferramentas de pesquisa: análise documental (relatórios da LOA, legislações e vídeos das audiências públicas), survey (aplicado aos participantes das audiências de 2014) e entrevista semiestruturada (com os parlamentares que fazem parte da Comissão de Finanças). A análise aponta para a pouca efetividade das audiências a partir da combinação de vários fatores, entre eles a baixa institucionalização, o perfil dos participantes, a influência do poder Executivo no processo a partir de sua relação com os parlamentares e o uso das emendas parlamentares como estratégia eleitoral. O estudo apresenta uma alternativa metodológica para avaliar a efetividade da participação a partir da interação entre os fatores endógenos e exógenos, que inclui a relação Executivo-Legislativo.
A virada ideacional: quando e como ideias importam
Authors: Perissinotto Renato , Stumm Michelli Gonçalves
Published: January 2018

Resumo O ensaio bibliográfico analisa a literatura que ficou conhecida como virada ideacional. Seu objetivo é, primeiro, resumir as críticas dessa literatura às perspectivas institucionalistas com as quais ela dialoga; segundo, sistematizar suas vantagens teóricas e, por fim, identificar o ferramental metodológico utilizado pelos autores que se filiam a ela. O ensaio baseia-se na análise de uma ampla gama de livros e artigos publicados sobre o assunto nos últimos 20 anos. Por meio dessa revisão bibliográfica, fomos capazes de mostrar como a literatura da virada ideacional permite incluir as ideias nas explicações dos fenômenos políticos. A inclusão das ideias, por sua vez, exige uma postura metodológica pluralista que pode significar avanços importantes para a ciência política.
Práticas de política econômica: um teste das atas do Comitê de Política Monetária do Banco Central do Brasil (2003-2014)
Authors: Ribeiro Andrea
Published: January 2018

Resumo Falta uma análise discursiva mais profunda sobre os temas de política econômica e suas implicações, sob a perspectiva da Ciência Política. Nesse sentido, o objetivo do artigo é testar o uso da análise textual como ferramenta de pesquisa em política econômica. Busca-se analisar textualmente as atas das reuniões do Comitê de Política Monetária (COPOM) do Banco Central (Bacen) produzidas entre 2003 e 2014, de modo a identificar as variações dos termos e verificar se há alguma relação positiva entre os termos identificados e o modo como a política econômica foi conduzida durante os três governos do Partido dos Trabalhadores (PT). Essa avaliação é feita a partir do uso do software de análise textual Iramuteq, considerando-se os momentos de inflexão na política econômica, assim como os momentos de maior aproximação e distanciamento entre o Bacen e o Ministério da Fazenda. A pesquisa envolveu o levantamento das atas do COPOM, extraídas da base de dados do Bacen disponível na internet, sua seleção e tratamento para análise e a produção de nuvens de palavras e gráficos de similitude. Como teste da hipótese, esperava-se identificar esses pontos de inflexão na fonte primária na variação de termos. O uso do “text mining” em estudos de política econômica é recente. A vantagem de testar a hipótese usando essa ferramenta é abrir a “caixa preta” da produção de política econômica. Isso permite (1) um melhor conhecimento dos termos utilizados e suas implicações; (2) análises temporalmente mais abrangentes que escrutinem uma grande quantidade de dados simultaneamente. Foi possível identificar e perceber a variação ao longo do tempo dos termos utilizados e de sua distribuição, o que confirma parcialmente a hipótese inicial. Embora essas variações sejam bastante sutis, em função do tratamento e da restrição temporal da amostra (que contemplou apenas governos de um mesmo partido), é possível afirmar que esse tipo de estudo traz novas oportunidades analíticas. Os resultados obtidos apontam para a necessidade de, primeiro, combinar estudos que utilizam fontes tradicionais (discursos oficiais, notícias e matérias) com o uso de fontes primárias e menos trabalhadas por especialistas. Segundo, apontam para a necessidade de aprofundar o conhecimento sobre softwares de análise de texto. Por último, indicam que dentro da linha de estudos vinculados ao institucionalismo discursivo, especialmente no Brasil, há ainda uma grande lacuna que deve ser preenchida.
C*-Álgebras e a Descrição da Mecânica Quântica
Authors: Floquet Sergio , Castro Júnior Augusto A. de , Trindade Marco A. S. , Vianna J. David M.
Published: January 2018

Neste artigo apresentamos a Teoria das C *-Álgebras. Demonstramos dois importantes resultados que são: o Teorema de Gelfand, que associa toda C *-Álgebra Abeliana às funções contínuas sobre um espaço Hausdorff compacto, e o Teorema de Gelfand-Neumark, que relaciona toda C *-Álgebra não Abeliana aos operadores lineares sobre um espaço de Hilbert. Em seguida, mapeamos a Mecânica Clássica dentro da teoria da C *-Álgebra, obtendo uma prescrição algébrica para os estados e às observáveis clássicas. Ao estendermos essa construção para o caso Quântico, preservando a prescrição algébrica e utilizando o Princípio da Incerteza, obtemos que os estados quânticos devem ser descritos por vetores do Espaço de Hilbert enquanto que os observáveis quânticos são os operadores auto-adjuntos sobre este espaço; discutimos brevemente sobre a Álgebra de Weyl.

Published: January 2018

Abstract Objectives: to assess alcohol intake prevalence and identify associated factors among pregnant women in the municipality of Rio Grande, RS, Brazil. Methods: this was a crosssectional study which included all parturient women residing in the municipality who gave birth in 2013. Two outcomes were characterized: alcohol intake during pregnancy and excessive alcohol intake during pregnancy. In the analysis, proportions were tested using the Chisquare test, whilst Poisson regression was used in the multivariate analysis. Results: 9.4% (CI95%= 8.210.5) of the 2,685 parturient women studied reported having consumed alcohol during pregnancy, with beer being most common beverage. Following adjustment, the factors associated with alcohol intake in pregnancy were: age ≥30 years, brown skin colour, living without a partner, low schooling, tobacco smoking and illicit drug use, having had more children and late onset of prenatal care. Excessive alcohol intake was found in 12.7% (CI95%= 8.616.9) of those who reported drinking during pregnancy and the factors associated with this practice were age ≥30 years, lower schooling and illicit drug use. Conclusions: this study found high alcohol intake during the gestation period and identified women more susceptible to this practice. There is an evident need for health professionals to work on preventing and handling alcohol intake among pregnant women in the municipality

Published: January 2018

Abstract Objectives: to evaluate the maternalfetal outcomes of thromboprophylaxis with enoxa parin based on scoring system in women with serum markers for hereditary thrombophilia and previous obstetric complications. Methods: a retrospective study was undertaken based on data collected from clinical records. We included 54 pregnant women with serum markers for hereditary thrombophilia undergoing therapeutic intervention with enoxaparin in the period from November 2009 to December 2013. The initial dose of low molecular weight heparin was guided by a scoring system. The maternalfetal outcomes of previous pregnancies and, subsequently, the treatment were compared using the chisquare (χ2) test with the Yates correction and Fisher's Exact Test; p<0.05 was considered significant. Results: we observed significant reduction in fetal/perinatal deaths (p<0.05) and spontaneous abortions (p<0.001) after intervention. The live births at fullterm delivery (p<0.001) and live births at preterm delivery (p<0.05) increased significantly after intervention. Conclusions: the therapeutic intervention with enoxaparin based on scoring system during pregnancy seems to improve the fetal prognosis.
Maternal mortality according to race/skin color in Mato Grosso do Sul, Brazil, from 2010 to 2015
Authors: Pícoli Renata Palópoli , Cazola Luiza Helena de Oliveira , Lemos Everton Ferreira
Published: January 2018

Abstract Objectives: to investigate the epidemiological profile, by race/skin color, of maternal deaths in the state of Mato Grosso do Sul, Brazil. Methods: the present epidemiological study of maternal death distribution by race/skin color was based on data extracted from Brazilian mortality and livebirth information systems from 2010 to 2015. The maternal mortality ratio and the specific maternal mortality ratio were calculated and analyzed according to obstetric variables. Results: the death risk for black (RR = 4.3, CI95%= 2.088.71) and indigenous women (RR = 3.7, CI95% 2.26.23) was approximately fourfold in comparison to the risk for white women. For direct causes of death, the state of Mato Grosso do Sul showed higher levels, 74.1%, as well as for most races/skin colors in the first triennium. The specific maternal mortality ratio was higher among black and indigenous women aged30 to 39 years old (416.7 and 651.8, respectively) per 100,000 live births (p<0.05). Conclusions: higher maternal mortality ratio for indigenous and black women and the predominance of deaths related to direct obstetric causes among race/skin color categories reflect inadequate health care during pregnancy and puerperium.

Published: January 2018

Abstract Objective: to analyze the clinical and epidemiological profile of poisoning in children and adolescents under 12years old. Methods: a crosssectional study with analytical component based on poisoning notifications at the Centro de Toxicologia de Pernambuco (Toxicological Center in Pernambuco), carried out in 2012 and 2014. Allergic reactions and contaminated food poisoning were excluded. Sociodemographic characteristics, type of toxic agent, circumstance, place of occurrence, time until care and patients' evolution were analyzed. The distribution of frequencies and associations among the variables through prevalence ratio and the chisquared test was determined. Results: Among 2,843 patients registered, 1,601 (56.3%) were poisoned by chemical substances and 1,242 (43.7%) by poisonous animals. Most lived in urban areas (90.6%) and were attended for care after an hour of the incident (47.6%). The poisoning frequency of chemical substances was higher among children under five years old (PR=2.34; CI95%= 2.142.56) and there was no difference in the sexes (PR=1.00; CI95%= 0.941.07). The predominant medicine (45.0%) for poisoning was between chemical substance and scorpions (77.0%). Poisoning occurred as accidental in 92.2% and 99.6% of chemical substance occurred at home. There were six deaths by chemical intake and two by scorpions.. Conclusions: poisoning in Pernambuco State is considered a public health issue given by its frequency and it occurred mostly with children under 5 years old accidentally and at home.

Published: January 2018

Abstract Objectives: assess the implementation of child mortality surveillance in Recife/PE. Methods: an analytical evaluative study was conducted on its implementation. It was a single-case study that correlated degree of implementation with the of the result indicators surveillance. A logic model on this strategy and a matrix of indicators and judgments according to model components were drawn up. The degree of implementation was obtained from structure and process indicators and this was then correlated with result indicators, in a deductive approach based on intervention theory. Results: the structure approach presented superior results to the process in all evaluated components. This strategy was considered to have been partially implemented (75. 7%), however, the components of 'identification of deaths' (85.7%), 'epidemiological research' (88.1%) and 'referral of proposals for promotion and health care and correction of official statistics' (95.8%) were classified implemented. Regarding the relation of the degree of implantation of the surveillance and its results with the logical model, only one of the 17 indicators was considered inconsistent. Conclusions: this strategy was considered to have been partially implemented. The model of child mortality surveillance and its assessment were shown to be adequate for signaling the consistency of the interrelations between the activities proposed and the effects expected, and would be reproducible within other scenarios.
Puerperal sepsis caused by liver abscess: case report
Authors: Silva Flávio Xavier , Souza Alex Sandro Rolland
Published: January 2018

Abstract Introduction: sepsis is a serious public health problem, affecting millions of people in the world each year, with a high mortality rate (one out of four patients) and an increasing incidence. Sepsis is one of the main causes of maternal mortality and an important cause of admission to obstetric intensive care units. Case description: In this study, the authors report the case of a woman having been submitted to cesarean section three days before presenting clinical signs of sepsis and septic shock caused by a liver abscess. The patient had a set of complications secondary to shock, such as thrombocytopenia, coagulopathy, toe ischemia and acute kidney failure. The patient had cholelithiasis and recurrent pain in the right hypochondrium during pregnancy. During hospitalization, the mechanism involved in the development of hepatic abscess was infection of the biliary tract. The patient was treated in an obstetric intensive care unit with antibiotics and drainage of the liver abscess. Progress was favorable and the patient was discharged in good health. Discussion: pyogenic liver abscess during pregnancy and puerperium is a serious condition which represents a diagnostic and therapeutic challenge, with few cases reported. The normally nonspecific clinical and laboratory findings can lead to a late diagnosis, which increases the risk of maternal morbidity and mortality.

Authors: Frizzas Marina Regina , Oliveira Charles Martins de , Omoto Celso
Published: January 2018

ABSTRACT: The genetically modified maize to control some caterpillars has been widely used in Brazil. The effect of Bt maize and insecticides was evaluated on the diversity of insects (species richness and abundance), based on the insect community, functional groups and species. This study was conducted in genetically modified maize MON810, which expresses the Cry1Ab protein from Bacillus thuringiensis Berliner, and conventional maize with and without insecticide sprays (lufenuron and lambda-cyhalothrin) under field conditions in Ponta Grossa (Paraná state, Brazil). Insect samplings were performed by using pitfall trap, water tray trap and yellow sticky card. A total of 253,454 insects were collected, distributed among nine orders, 82 families and 241 species. No differences were observed in the insect community based on the richness, diversity and evenness indices. Predators and pollinators were more abundant in genetically modified maize. Parasitoids, detritivores, sap-sucking herbivores and chewing herbivores were more abundant in conventional maize with insecticide sprays. Significant differences were found for the species Colopterus sp., Colaspis occidentalis (L.) and Nusalala tessellata (Gerstaecker) which were most abundant in Bt maize, and Dalbulus maidis and Condylostylus sp.2 in conventional maize.

ABSTRACT: The citrus pulp can be used as a substitute in ruminant feed reducing costs and maintaining the nutritional quality of food. However, this compound should be used carefully so as not to cause harm to the animals. The present report aims to describe the occurrence of dental erosion, actinomycosis and polioencephalomalacia in sheep raised and kept with a wet low pectin citrus pulp based diet, composing 50% of roughage. Actinomycosis was diagnosed in five animals through clinical and radiographic examinations and microbiological culture, and, after treatment, three animals were cured. Polioencephalomalacia was confirmed in ten animals by clinical diagnostics, in nine out of ten animals by therapeutic diagnosis, and in one animal by post-mortem anatomopathological examination. According to the observed, we recommend caution when large amounts of citrus pulp are used as bulky food.
Two methods for isolation of endophytic and edaphic Bacillus spp. from sugarcane fields
Authors: Ferreira Maria Elízia Pacheco , Leite Luís Garrigós , Polanczyk Ricardo Antônio , Suzuki Marise Tanaka , Freitas Raquel de Paula , Bueno Roselaine Nunes da Silva , Silva Raphael Satochi Abe da
Published: January 2018

ABSTRACT: Bacillus has been widely studied and used for the control of pests and diseases. The adapted protocol proposed by POLANCZYK (2004) proved to be more efficient than the one by the World Health Organization (WHO, 1985) to isolate edaphic strains of Bacillus. However, it has not been assessed for isolation of endophytic strains, which are much less abundant in the nature and more difficult to be isolated. This study aimed to compare two methodological procedures for isolation of Bacillus, established by the WHO (1985) and by POLANCZYK (2004), regarding their efficiency for isolation of endophytics and edaphics Bacillus strains from inside the root tissue of sugarcane, as well as from the associated soil sample, collected from 11 locations; and to compare the density of bacteria in both environments. Endophytic and edaphic strains of Bacillus were isolated by both procedures. However, the isolation protocol performed by POLANCZYK (2004) made more efficient by having a greater number of colony forming units (CFU) per gram of soil and root indicating that this procedure is more useful, especially for isolation of endophytic strains of Bacillus, which are much less abundant in the nature than edaphic strains, being therefore more difficult to be isolated. Using the Polanczyk protocol (2004), Bacillus strains were recovered from all roots (endophytic) and soil (edaphic) samples of all the 11 fields, suggesting that the plant root may be another important source for isolation of Bacillus besides the soil. Higher densities of Bacillus were isolated from the edaphic environment compared with the endophytic environment, with significant differences when isolated by Polanczyk method (2004).

Published: January 2018

ABSTRACT: The objective of this study was to evaluate the relative competitive ability of soybean with different development stages of hairy fleabane. Two experiments were conducted in greenhouse, in a completely randomized design. In the experiment it was tested soybean and hairy fleabane competition at different stage of development (rosette and 15 cm height) at the proportions 100:0, 75:25, 50:50, 25:75 and 0:100, and total plant population was 315 plant m-2. The variables evaluated were plant height, leaf area, and shoot dry matter (leaves and stems). Competitive analysis was performed by diagrams and interpreting the competitiveness index. The soybean has greater competitive ability that horseweed for both development stages. The intraspecific competition is more intense for soybean when in hairy fleabane rosette stage, and the competitive relations are equivalent between soybean and hairy fleabane of 15 cm tall. The both hairy fleabane stages were injured in the soybeans competition.

Authors: Penha Filho Rafael Antonio Casarin , Zancan Fábio Tavares , Almeida Adriana Maria de , Berchieri Junior Angelo
Published: January 2018

ABSTRACT: Salmonella enterica serovar Gallinarum biovar Gallinarum (SG) is a host-specific bacteria that causes the fowl typhoid (FT). This disease is highly pathogenic to commercial chickens, specially brown layers and breeders, causing acute septicemia followed by high morbidity and mortality. Vaccination is extensively adopted in the fields as a biosafety tool for prevention of isolated infections and outbreaks in commercial poultry flocks. The present study evaluated the use of an attenuated SG with deletions on genes cobS and cbiA (SGΔcobSΔcbiA) as a live vaccine, using vaccination schemes adjusted for field conditions. To this end, brown layers were used in two different experiments, to evaluate the long-term protection, necessary in the fields. The vaccination scheme on the first experiment consisted of two doses, the first at 4 th week-of-age and the booster dose at 8 th week-of-age with challenge at 16 th week-of-age with wild SG strain. On the second experiment, the vaccination was carried out by different routes using three doses of the live vaccine, at 4 th , 8 th and 12 th weeks-of-age, and the challenge was done at 20 th weeks-of-age. After the challenge, the mortality was recorded during 28 days, and the egg production (experiment 2) was evaluated and compared with the group of unvaccinated layers. In both experiments, the mortality was significantly reduced, and the egg production was not affected in vaccinated layer-hens. In summary, this study shows the efficacy and the protection of different vaccination schemes against FT that can be applied under field conditions in commercial poultry farms.

Published: January 2018

RESUMO: O objetivo deste trabalho foi avaliar a melhor dose de atrazina no controle de plantas de soja em meio ao milho safrinha consorciado com Brachiaria ruziziensis (B. ruziziensis), bem como sua interação com diferentes doses de nicosulfuron, de forma a não afetar os benefícios do consórcio. Foram realizados dois bioensaios, o primeiro com seis doses de atrazina (0; 0,6; 0,8; 1,0; 1,2; e 1,4 kgi.a. ha-1). As avaliações foram realizadas 15 e 30 dias após a aplicação (DAA), baseadas na porcentagem de controle das plantas de soja, no número de plantas de B. ruziziensis, no rendimento de grãos de milho e na massa seca do capim. O segundo bioensaio foi conduzido em esquema fatorial 3 (doses de nicosulfuron) × 2 (sem e com atrazina), com duas testemunhas adicionais (testemunha capinada e testemunha sem capina). As doses de nicosulfuron utilizadas foram 2,0; 4,0; e 6,0 gi.a. ha-1, e a dose de atrazina foi de 0,8 kgi.a. ha-1. Doses crescentes de atrazina resultaram em melhor controle das plantas de soja e maior rendimento de grãos de milho. Doses superiores a 1,0 kgi.a. ha-1 de atrazina resultaram em redução na massa seca do capim. A adição de 0,8 kgi.a. ha-1 de atrazina com 2,0; 4,0; ou 6,0 gi.a. ha-1 de nicosulfuron aumentou o controle de plantas de soja em comparação com as doses isoladas de nicosulfuron, não influenciou o número de plantas e a massa seca do capim e proporcionou incremento no rendimento de grãos de milho.

ABSTRACT: Vatiga illudens is a pest of economic importance for the cultivation of cassava. Knowing the time of incidence of this insect in combination with environmental factors enables control strategies. The objective of this study was to determine the population dynamics of V. illudens in cassava cultivars and the correlation of these insects for climatic factors in Dourados, Mato Grosso do Sul. Four cultivars of cassava were evaluated: Kiriris, N-25, IAC 90 and Fécula Branca. Population assessment of the lace bug was conducted over 18 months observing 2 crop cycles. Fortnightly, they were randomly sampled four central plants of each plot and five leaves from the middle third of each plant, quantifying the number of nymphs and adults per leaf. Twenty months after planting cassava, two central rows of each plot were harvested and measured productivity in kg ha-1. The experimental design was randomized blocks with four treatments and two replications. The peak population of nymphs and adults for the first crop cycle occurred during the months from March to May. For the second cycle, these population indices happened in the months from January to April. Cultivar Kiriris showed the highest mean number of nymphs and adults per leaf cassava and cultivar IAC 90, the lowest number of insects. There was a negative correlation between the population of adult insects and root yield. The maximum, mean and minimum temperatures affected the population of nymphs V. illudens. These results are fundamental to define management strategies for control of lace bug.

ABSTRACT: The objective of this study was to assess the resistance of tomato genotypes with high foliar levels of allelochemicals to the leafminer Liriomyza trifolii. Eight tomato genotypes with contrasting levels of three different alellochemicals were tested for leafminer resistance: the TOM-687 and TOM-688 lines, which are both rich in acylsugar; ZGB-703 and ZGB-704, which are rich in zingiberene; BPX-365G-899-07-04-02 and BPX-367E-238-02, which are rich in 2-tridecanone; and 2 standard commercial hybrids (Deborah Max and Bravo F1) with low-allelochemical content. Thirty days after being transplanted, nine potted plants of each of the treatments were transferred to a phytotron chamber, into which 1600 unsexed leafminer adults from a mass rearing were released. The number of mines and the percentage of leaves and leaflets attacked (= with the presence of punctures) were evaluated. Six days later, the number of pupae was recorded. The genotypes with high levels of acylsugar were associated with higher levels of resistance to leaf miner L. trifolii, through antixenosis and antibiosis mechanisms. At least one of the 2-tridecanone-rich lines (BPX -365G-899-07-04-02) showed some level of resistance via an antibiosis mechanism.

ABSTRACT: Fish are considered rich sources of nutrients. Health care throughout its production chain aims to ensure quality, minimizing the risks of transmission of foodborne diseases. In order to evaluate the microbiological quality of trahira fish (H. malabaricus), 40 samples were analysed for Most Probable Number (MPN) of coliforms at 45ºC, counts of aerobic mesophilic bacteria and Staphylococcus spp., identification of E. coli, Salmonella spp. and Aeromonas spp.. Analyses were conducted according to official methods, procedures, and recommendations. Microbiological results showed coliform values at 45 °C ranging from <3 to > 1.1 × 103 MPN/g, presence of E. coli in 14 (35%) samples, counts of mesophilic aerobic bacteria from 9 × 102 to 109 CFU/g and absence of coagulase positive Staphylococcus aureus. Salmonella spp. was detected in 2 (5%) samples, which is in disagreement with the standards required by the RDC Nº 12 of January, 2001 (ANVISA) regarding Aeromonas spp. In total, 36 (90%) samples were contaminated, 7 (19.4%) by A. cavie and 29 (80.6%) by A. hidrophila. The results of this research showed unsatisfactory hygienic and sanitary conditions of fish from the municipality of São Bento (MA), exposing consumers to the risk of foodborne diseases.

ABSTRACT Reduced-impact logging is a well known practice applied in most sustainable forest management plans in the Amazon. Nevertheless, there are still ways to improve the operational planning process. Therefore, the aim of this study was to create an integer linear programming (ILP) to fill in the knowledge gaps in the decision support system of reduced impact logging explorations. The minimization of harvest tree distance to wood log landing was assessed. Forest structure aspects, income and wood production were set in the model, as well as the adjacency constraints. Data are from a dense ombrophylous forest in the western Brazilian Amazon. We applied the phytosociological analysis and BDq method to define the selective logging criteria. Then, ILP models were formulated to allow the application of the constraints. Finally, 32 scenarios (unbalanced forest, UF, and balanced forest, BF) were generated and compared with real executed plans (RE). Robust results were achieved and the expected finding of each scenario was met. The feasibility to integrate ILP models in uneven-aged forest management projects was endorsed. Consequently, the UF and BF scenarios tested were efficient and concise, introducing new advances for forest management plans in the Amazon. The proposed models have a high potential to improve the selective logging activities in the Amazon forest.

ABSTRACT The Amazon Basin is a center of diversity of Gossypium barbadense and the strategy for conservation of this genetic resource depends on the knowledge of the diversity maintained in Amazonas State. During two expeditions, in 2012 and 2014, plants were collected in ten municipalities in the state of Amazonas, in the central Brazilian Amazon region. The molecular diversity was estimated by SSR markers for 50 samples collected in 2012. The morphological diversity of 24 plants collected in 2014 was assessed ex situ and compared to that of 50 plants of the same and other cotton varieties from other Brazilian states. Most of plants evaluated in situ in Amazonas had purple petioles and veins (82%), associated to medicinal use, and kidney seeds (78%). The ex situ morphological analysies showed that G. barbadense plants from the Amazonas state: i) presented higher similarity to cotton plants from other northern Brazilian states, and ii) were grouped separately from those of other northern Brazilian states by descriptor analysis. Both the molecular (H=0.41) and morphological (H=0.38±0.02) diversity among the collected plants was considered intermediary. Our study indicates the distinctiveness of Amazon cottons, and contributes to demonstrate the discrimination power of multicategorical traits.

ABSTRACT The Amazonian white-sand vegetation presents a set of unique features, such as the dominance of a few species, high endemism and low species richness, which differentiate it from other Amazonian forests. Soil parameters have long been recognized as the main drivers of white-sand vegetation (WSV) characteristics. However, how they influence the composition, richness and structure of this vegetation type is still poorly understood. In this study we investigated the variation in floristic composition between patches and the soil-vegetation relations in three central Amazonian WSV patches. We tested whether slight differences in soil properties are linked with differences in floristic composition, species richness and forest structure in adjacent patches. In each patch three plots of 50 x 50 m were sampled (a total of 2.25 ha). Soil samples were collected for each plot. The sampling cutoff for arboreal individuals was DBH ≥ 5 cm. We sampled a total of 3956 individuals belonging to 40 families and 140 species. In each patch only a few species were dominant, but the dominant species varied among patches. Differences among patches were significant, but plots in the same patch tended to have similar species composition. The variable sum of bases (SB) was directly related to species composition, however, species richness and forest structure were not related to soil parameters. Even small variations in soil parameters can change species composition in WSV, although these variations do not necessarily influence the richness and other structural parameters.

ABSTRACT The strategies to control the cattle tick, Rhipicephalus microplus are based mainly on the use of synthetic pesticides. However, the emergence, establishment, and development of resistance of ticks is rendering the main chemical groups ineffective. Finding new molecules to effectively control infestations by R. microplus is necessary to maintain the productivity of cattle herds, particularly of taurine breeds established in equatorial and tropical regions of the world. Ethanol extracts from the leaves, stems, and fruits of Piper tuberculatum were evaluated in bioassays at concentrations of 50, 25, 12.50, 6.25, 3.12 and 1.56 mg mL-1. The concentrations lethal to 50% of the individuals (LC50) of tick larvae after 24 hours of exposure were 3.62, 3.99 and 5.30 mg mL-1 for fruit, stem and leaf extracts, respectively. Against the engorged females, the highest efficacy rates were obtained at the concentration of 50 mg mL-1, corresponding to 71.57%, 68.38% and 37.03% of the fruit, leaf and stem extracts, respectively. The main effect of the ethanol extracts was on the egg hatching rate of ticks, with a reduction of 55.63% for the fruit and leaf extracts, and 20.82% for the stem extract. The results show that P. tuberculatum is a promising source of molecules for use as active ingredients in pesticide formulations for R. microplus control.
