Novo registro de Trichospilus diatraeae Cherian & Margabandhu, 1942 (Hymenoptera: Eulophidae), como parasitóide de Spodoptera cosmioides Walker, 1858 (Lepidoptera: Noctuidae) no Brasil

Spodoptera cosmioides (Lepidoptera: Noctuidae)é uma espécie polífaga e alimenta-se de grande número de plantas cultivadas e espontâneas. No Brasil, as culturas do abacaxi, algodoeiro, arroz, berinjela, cebola, eucalipto, pimentão e tomateiro, entre outras hortaliças, são consideradas hospedeiras da praga. Entretanto, apesar da ampla gama de hospedeiros, sua ocorrência como praga é relatada relacionada a desequilíbrios provocados pelo uso excessivo de inseticidas de amplo espectro, o que vem causando a resistência da praga a inseticidas. Devido a essa complexidade, métodos alternativos de controle têm sido propostos, por exemplo, o controle biológico através da utilização de parasitóides. Trichospilus diatraeae (Hymenptera: Eulophidae) é um parasitóide gregário pupal preferencialmente de espécies da ordem Lepidoptera. Este é o primeiro relato de T. diatraeae parasitando pupas de S. cosmioides, parasitóide que oferece novas perspectivas para os programas de controle biológico.

Permanência de Walflan de Queiroz: uma leitura da obra O Testamento de Jó

Este trabajo tiene como objeto de investigación literaria la obra: O testamento de Jo , lanzada en 1965, por Walflan de Queiroz. El poeta norte-río-grandense ilustra a través de un conjunto de poemas su experiencia religiosa y metafísica a partir de la desgracia sufrida por el personaje bíblico Jo, desarrollando una estética de la soledad, de la pobreza y de la marginalidad. Según Alter y Kermode (1997), la poesía de Jo es asombrosa en su fuerza e inventiva. Se pretende demostrar que las poesías de Walflan de Queiroz poseen dos corrientes definidas: si, por un parte, se vinculan al tema de Jo, mon doux Job , como él escribió en un poema; por otra, diseminan una postura amorosa. Con el objetivo de situar al autor y a su obra, se discuten el contexto histórico y la agitación cultural en Río Grande do Norte en la década de 1960. La lectura de O testamento de Jo nos llevó a realizar inicialmente una comparación de la poética walflaniana con textos bíblicos para la construcción de una atmósfera mística en el libro. Enseguida, el abordaje de los poemas amorosos que retratan la imagen femenina presente de forma platónica o bajo el velo de la mitología, de los mitos de Orfeu y Eurídice, retomados por el poeta. En Walflan de Queiroz, el amor no se concretiza. Y el bardo escribe como los románticos y los simbolistas

Em busca de um novo indicador Espectroscópico do período de rotação das Estrelas do tipo solar

The study of sunspots consistently contributed to a better understanding of magnetic phenomena of the Sun, as its activity. It was found with the dynamics of sunspots that the Sun has a rotation period of twenty-seven days around your axis. With the help of Project Sun-As-A-Star that solar spectra obtained for more than thirty years we observed oscillations of both the depth of the spectral line and its equivalent width, and analysis of the return information about the characteristics of solar magnetism. It also aims to find patterns of solar magnetic activity cycle and the average period of rotation of the Sun will indicate the spectral lines that are sensitive to magnetic activity and which are not. Sensitive lines how Ti II 5381.0 Å stands as the best indicator of the solar rotation period and also shows different periods of rotation cycles of minimum and maximum magnetic activity. It is the first time we observe clearly distinct rotation periods in the different cycles. The analysis also shows that Ca II 8542.1 Å and HI 6562.0 Å indicate the cycle of magnetic activity of eleven years. Some spectral lines no indicated connection with solar activity, this result can help us search for programs planets using spectroscopic models. Data analysis was performed using the Lomb-Scargle method that makes the time series analysis for unequally spaced data. Observe different rotation periods in the cycles of magnetic activity accounts for a discussion has been debated for many decades. We verified that spectroscopy can also specify the period of stellar rotation, thus being able to generalize the method to other stars

Validade e reprodutibilidade do Wii Balance Board para avaliação do equilíbrio vertical estático: um novo método de avaliação.

The Wii Balance Board (WBB) began to be investigated as a low-cost alternative for assessing static balance in vertical posture. However, studies employed methodological procedures that did not eliminate result variability between the tests and equipment used. Objective: Determine the validity and reproducibility of the WBB as an instrument for assessing static balance in the vertical position, using simultaneous data analysis and superimposed equipment. Methods: This is an accuracy study of 29 healthy young individuals of both sexes aged 18 to 30 years. Subjects were assessed 24h apart (test-retest), using unipodal and bipodal support tests, with eyes closed and open. To that end the WBB was placed on top of a force platform (FP) and data (postural sway) were collected simultaneously on both devices. Validity and reproducibility were analyzed using the interclass correlation coefficient (ICC). Finally, Bland-Altman analysis was applied to assess agreement. Results: The sample was composed of 23 women and 6 men, with mean age of 24.2±6.3 years, 60.7±6.3 kg and 1.64±4.2 m. The validity of the WBB compared to the FP was excellent for all 4 tasks proposed (ICC = 0.93 0.98). The reproducibility analyzed by test-retest was excellent for the bipodal support tasks (ICC = 0.93-0.98) and only moderate for the unipodal support tests (ICC = 0.46 0.70). Graphic analysis exhibited good agreement between the devices, since most of the measures were within the limits of agreement. Conclusion: this study proved the validity and reproducibility of the Wii Balance Board as an instrument for assessing static balance in vertical posture, using simultaneous analysis with superimposed equipment. Thus, the WBB has been increasingly used by physical therapists and other health professionals in their clinical practice, as both a rehabilitation and assessment tool

Desenvolvimento de um novo complexo macrocíclico do sistema cobalto cyclam

In this work were synthesized and studied the spectroscopic and electrochemical characteristics of the coordination compounds trans-[Co (cyclam)Cl2]Cl, trans- Na[Co(cyclam)(tios)2], trans-[Co(en)2Cl2]Cl and trans-Na[Co(en)2(tios)2], where tios = thiosulfate and en = ethylenediamine. The compounds were characterized by: Elemental Analysis (CHN), Absorption Spectroscopy in the Infrared (IR), Uv-Visible Absorption Spectroscopy, Luminescence Spectroscopy and Electrochemistry (cyclic voltammetry). Elemental Analysis (CHN) suggests the following structures for the complex: trans- [Co(cyclam)Cl2]Cl.6H2O and trans-Na[Co(cyclam)(tios)2].7H2O. The electrochemical analysis, when compared the cathodic potential (Ec) processes of the complexes trans- [Co(cyclam)Cl2]Cl and trans-[Co(en)2Cl2]Cl, indicated a more negative value (-655 mV) for the second complex, suggesting a greater electron donation to the metal center in this complex which can be attributed to a greater proximity of the nitrogen atoms of ethylenediamine in relation to metal-nitrogen cyclam. Due to the effect of setting macrocyclic ring to the metal center, the metal-nitrogen bound in the cyclam are not as close as the ethylenediamine, this fact became these two ligands different. Similar behavior is also observed for complexes in which the chlorides are replaced by thiosulfate ligand, trans-Na[Co(en)2(tios)2] (-640 mV) and trans-Na[Co(cyclam)(tios)2] (-376 mV). In absorption spectroscopy in the UV-visible, there is the band of charge transfer LMCT (ligand p d* the metal) in the trans-Na[Co(cyclam)(tios)2] (350 nm, p tios  d* Co3+) and in the trans-Na[Co(en)2(tios)2] (333 nm, p tios d* Co3+), that present higher wavelength compared to complex precursor trans- [Co(cyclam)Cl2]Cl (318 nm, pCl  d* Co3+), indicating a facility of electron density transfer for the metal in the complex with the thiosulfate ligand. The infrared analysis showed the coordination of the thiosulfate ligand to the metal by bands in the region (620-635 cm-1), features that prove the monodentate coordination via the sulfur atom. The νN-H bands of the complexes with ethylenediamine are (3283 and 3267 cm-1) and the complex with cyclam bands are (3213 and 3133 cm-1). The luminescence spectrum of the trans-Na[Co(cyclam)(tios)2] present charge transfer band at 397 nm and bands dd at 438, 450, 467, 481 and 492 nm.

Violência nas escolas: Um novo olhar ante as relações sociais

The most varied ways of manifestation of the violence phenomenon in the contemporary society are each time more found in the media spaces and among society discussions. It makes think about procedures to be taken before the growth and new outbreaks of such phenomenon. The violences manifestations in schools reveal themselves as a reflection of what happens in the scope of social violence. Its dynamics originates in society and reflects itself in scholl, that is, the violences in schools combine internal and external elements to school enviroment of many fields and spheres of which the individuals participate. To reflect about the violences in the schools requires, over all, to make a bridge with the categories: youth and violence. Violences in schools: A new look to the social relations, is a Ms. Sc. Dissertation that has as main objective: to analyze the main existing forms of violence in the school space. For its achievement, it was made a bibliographical survey, questionnaires application (annexed) and observation. Thus, this research articulated the two approaches: qualitative and quantitative. The questionnaires application happened in a state school of the Natal city and amongst yhe criteria for this choice there was the fact of the school had more than 500 pupils, to be located on a strategical place of the city, providing a subjects heterogeneity to be researched, deyond the limitations of available resources financial and material and the available time for the research accomplishment. The scool congregates objective conditions, specifically in what concerns the criteria previously defined: age range, socioenomical level and number of pupils. Amongst the main results obtained, it can be detached that the violence is a phenomenon seen, for the great majority of the research subjects, as a phenomenon connected to the most visible violence forms: the agressions. And a question always present in the public education institutions: infrastructures precariousness, high scool evasion índex and vulnerability among the pupils that makes possible to the pupil to see school as an home extension. Such dissertation concludes that the phenomenon of the violence in scools demands and requires of the most varied subjects involved in the processes na understanding of its determinants so that thus, one can intervene in such phenomenon that does not restrains itself to the physical acts of aggression, but that it is, over all, on a non respecting the different

Do novo sindicalismo à concertação social: ascensão (e crise) do sindicalismo no Brasil (1978-1998)

La trajectoire du syndicalisme au Brésil de 1978 à 1998 se présente comme un passage, sur le plan de la stratégie syndicale, de la confrontation à la coopération conflictuelle, ou encore, de la lutte des classes dans la production vers une «convergence antagonique», ou un syndicalisme de participation ou de «concertation sociale», qui s'avère précisement un défensivisme nouveau, d'apparence néo-corporative. Ce que nous cherchons à caractériser ici est l'importance progressive dans la pratique syndicaliste prépondérante de la CUT dans les années 90 du nouveau corporatisme ouvrier, qui a tendance à affaiblir la perspective de classe qui a caractérisé la lutte politique et syndicale au Brésil dans les années 80.

Experiência preliminar com novo filtro de veia cava: resultados de 15 implantes

Este estudo apresenta resultados preliminares obtidos com um novo filtro permanente de veia cava, baseado no desenho de Greenfield, com três hastes prolongadas de um total de seis, para dar estabilidade central ao filtro na luz da veia cava. Neste artigo, relatamos sua avaliação clínica preliminar quanto à aplicabilidade, eficácia e segurança. de agosto de 2004 a dezembro de 2006, 15 filtros foram implantados em nove homens e seis mulheres, com idades variando de 38 a 79 anos (média de 57,8 anos). O acesso foi feito sempre por via transjugular. As indicações foram: trombose venosa proximal, com contra-indicação de anticoagulação em 12 pacientes; complicações hemorrágicas com anticoagulação em dois pacientes; e embolia pulmonar, apesar de anticoagulação adequada, em um paciente. Os filtros foram avaliados quanto à liberação, inclinação, mau posicionamento e perfuração de cava. No seguimento, avaliou-se trombose no local de acesso, tromboembolismo venoso recorrente, migração do filtro e trombose de cava pelo ultra-som. Nenhum paciente recebeu anticoagulantes no seguimento. O filtro foi liberado com sucesso em todos os casos sem mau posicionamento, inclinação, perfuração ou trombose de acesso. Os pacientes foram seguidos entre 3 e 23 meses (média de 11 meses). Nenhum paciente teve recorrência de tromboembolismo venoso. Não houve casos de trombose de veia cava ou migração do filtro. Óbito ocorreu em sete casos, todos relacionados com a moléstia de base. Os resultados preliminares indicam potencial eficácia e segurança do uso do novo filtro no período estudado.

Atuação e interação de stakeholders no processo de implantação do turismo: um estudo no município de Sitio Novo/RN

The present work is a study which deals about the stakeholder approach towards the issue of tourism development in a city of Rio Grande do Norte state: Sítio Novo. As a goal, we sought to understand the stakeholders action and interaction mechanisms in the implementation process and, consequently, tourism planning in the municipality. Regarding to the methodology, the study is characterized as an exploratory and descriptive research with a qualitative approach, given the intention of trying to understand meanings and situational characteristics presented by the research subjects. The interview was the instrument used to collect information, and it was performed with 10 (ten) actors of tourism in the municipality, documents about tourism development (Proceedings of the Regional Council of Polo Agreste Trairi were analyzed Sítio Novo municipality incorporates the Polo, and the Strategic Plan for Tourism). The study shows that public actors are the majority in the destination, notes that there is a minimal involvement of civil society in actions for tourism in the municipality, highlights that representatives of the municipality participate effectively in meetings of the Regional Council of Tourism Polo Agreste Trairi, to discuss actions related to the development of the activity in the locality, and attests that local actors interviewed, mostly understand their functions regarding to tourism development, however, do not perform actions consistent with the role they have, which have as purpose the planning and development of tourism. For that matter, this paper concludes that the participation and coordination among the stakeholders of the municipality should be reconsidered in order to seek and/or propose alternatives that gather in a more adequate way the local actors, so that something more effective about the tourism development in the destination could be done

Lupus eritematoso sistêmico: novo fator de risco para aterosclerose?

OBJETIVO: Avaliar a prevalência de eventos cardiovasculares (ECV) secundários à aterosclerose em pacientes com lupus eritematoso sistêmico (LES) e correlacioná-los aos tradicionais fatores de risco, tempo de doença e drogas utilizadas na terapia. MÉTODOS: Estudo retrospectivo através da coleta e análise dos dados contidos nos prontuários de pacientes com diagnóstico confirmado há no mínimo dois anos e seguidos desde 1992. Foram considerados ECV: angina do peito (AP), IAM e acidente vascular cerebral (AVC) de causa não relacionada à atividade do LES. Foram computados os fatores de risco para aterosclerose e dados sobre tratamento. RESULTADOS: Foram analisados 71 prontuários. A média de idade dos pacientes foi de 34,2±12,7 anos; 68 mulheres e três homens; 58 caucasóides (81,6%). Dez (14,08%) apresentaram ECV. Os pacientes nos quais os eventos cardiovasculares foram observados apresentavam idade mais elevada (42,7 vs 32,8 anos p=0,0021) e maior tempo de doença (10,8 vs 7,2 anos p=0,011). Os tradicionais fatores de risco, as doses diárias e cumulativas de esteróides, imunossupressores e antimaláricos não apresentaram diferença estatística significante entre pacientes que apresentaram ou não ECV. CONCLUSÃO: A prevalência de secundários à aterosclerose no LES foi semelhante ao da literatura, 14,08%. Os tradicionais fatores de risco não mostraram associação com a ocorrência ou não de ECV no LES. Os pacientes nos quais os eventos cardiovasculares foram observados apresentavam idade mais elevada e maior tempo de doença. É precoce estabelecer-se que o LES possa ser um fator independente no desenvolvimento da aterosclerose.

Terra e trabalho: permanência de uma política pública na Fazenda Mundo Novo, em Caicó-RN

This is study about the Project Vazantes, as a case of stay policy on access to land upstream of the weir humid New World, in Caicó-RN. It includes social and economic aspects of vazanteiros, that in their experiences with the land, recreate structures, forms and functions. Theoretically, the work is based on the ideas miltonianas (1986, 1988, 1996, 1997) on the production and reproduction of space, as seen this system of actions that is articulated to the public policies and the achievements solidarity, to the extent that production, in vazantes there is virtually no technology investment, technical assistance and rural credit. Regarding the search procedures, we conducted interviews and questionnaires with vazanteiros applied but did photographic records and research into documentary sources Agricultural Research Company's Rio Grande do Norte S / A (EMPARN), the Union of Rural Workers of Caicó (STRC ), In newspapers and magazines, as well as other sources of information related to the object of study.Such procedures, coupled with theoretical and methodological benchmarks, helped in the understanding of the relationship that takes place in the New World Farm, in order that space produced by actors (EMPARN and vazanteiros) comprises a structure of power that involves multiple interests in extent that land and labor are appropriate mechanisms as dialetizantes
