Controle de plantas daninhas em cana-de-açúcar (Saccharum officinarum) com hexazinone e suas misturas com diuron, em pré-emergência

Foi realizado no ano agrícola 1976/77 um experimento em solo arenoso na Usina Utinga/LeãoAL, no qual foram testados em pré-emergência os tratamentos: hexazinone em 4 doses; hexazinone + diuron em 3 doses; diurom + 2,4 D amina e ametrina + 2,4 D amina. Aos 47, 78 e 111 dias, efetuaram-se as avaliações de fitotoxicidade à cana-de-açúcar e controle à Digitaria sanguinalis , Colopogonio sp, Paspalum distichum e Wedellia paludosa. A interpretação dos dados obtidos mostrou que os tratamentos com hexazinone (954 g/ha) e hexazinone (719 g/ha) + diuron (2048 g/ha) apresentaram diferença estatística em relação à produção quando comparadas à testemunha, além de serem eficientes no controle às plantas daninhas presentes no experimento. Nenhum tratamento prejudicou as qualidades tecnológicas da cana-de-açúcar.

A reestruturação produtiva e as novas formas de organização do trabalho: a experiência do transporte alternativo no município de Belém/PA

The study made in this thesis analyzes the new form of work organization at the urban collective transportation sector, so called Altemative Transportation which is a new form of public transportation that appears in the Brazilian urban context by the mid ninety' s, this work is made by independent or sub-contracted workers, usually organized in cooperatives . It reflects the investigation of new forms of precarious work, unformal which has been expanding in the urban transportation sector. Thus, discusses non regulation of the services sector problem the ways of survival of exc1uded workers from the formal work market mainly afier the capital productive restructure. It has as privileged area of investigation, the sector policy of urban transportation that make field of the main nets of political articulations that define the dynamic of the urban space. It is known that the urban collective transportation allows the access to the production, circulation and general consumption being necessary to the mobility of the resident population, mainly to those with low purchasing capacity. It becomes a field of empirical investigation at the Belem municipal, located at the Amazonic region - north Brazil. The main points dealed on this research start from concrete relations from the daily life of workers that deve1op their activity on the altemative transport mediated with theoretical references needed for understanding and interpretation of the studied reality. The investigation strategies were built from the abstract (theorical knowledge produced for the reality analyze) in concrete by the investigation quantitative-qualitative from this area of urban policy, making up possible the formation of a references chart to the analyses of the studied subject. Rescue his historicity, from characterization of the urban space of the metropolitan region of Belem passing true the forms of organization and urban services performances while essential production and reproduction element of the social relations. Identifies the main individuals that historically have been participating in the construction of the municipality transport policy and the ways of expression of the local political strength relations. Outstand the State paper on the net of established relations near the local power, as well as outstand the importance of social sciences in the understanding of urban policies in the transportation area, trying to bring input to the academicals -scientific debate .The above e1ected and mentioned points in this study are crucial for a critical reflection of the transportation policies. That relation is not given, but historically built at the power relation chart that makes up this unique area of the urban policies

Identificação de genes cry de Bacillus thuringiensis no controle de Sphenophorus levis, o bicudo da cana-de-açúcar

A bactéria B. thuringiensis caracteriza-se pela produção de proteínas tóxicas a representantes de diversas ordens de insetos, as quais são codificadas por genes cry. Este trabalho foi realizado com objetivo de selecionar isolados de B. thuringiensis, por meio da caracterização morfológica e molecular, identificando as diferentes subclasses dos genes cry3 e cry35 e determinar a patogenicidade contra Sphenophorus levis, uma das mais importantes pragas da cultura da cana-de-açúcar. Foram utilizados 1163 isolados de B. thuringiensis e com a observação em microscópio com contraste de fases foram confirmadas como pertencentes à espécie de B. thuringiensis. O material genético foi purificado pela matriz de troca iônica Instagene Matrix e submetido a PCR com iniciadores gerais cry3 e cry35 identificando-se 30 isolados contendo genes com potencial para o controle de coleópteros, os quais juntamente com as linhagens-padrão de B. thuringiensis var. tenebrionis, B. thuringiensis var. morrissone e B. thuringiensis var. tolworthi foram utilizados para a realização do bioensaio. Através de análise discriminante alocaram-se os isolados em quatro grupos quanto à toxicidade de B. thuringiensis. Os grupos ficaram assim definidos: um grupo que promovem até 10% de mortalidade contendo as testemunhas e duas linhagens;um grupo que causou 39% de mortalidade contendo três linhagens padrão e dez isolados; um grupo com 52% de mortalidade contendo treze isolados e um grupo com 70% de mortalidade contendo cinco isolados, os quais devem ser considerados promissores no controle biológico de S. levis.

Modo de aplicação e eficiência de inseticidas granulados sistêmicos para o controle de cigarras (Hemiptera: Cicadidae) do cafeeiro

Avaliou-se a eficiência de métodos de aplicação de inseticidas granulados sistêmicos para o controle das cigarras Quesada gigas (Olivier) e Dorisiana drewseni (Stål) do cafeeiro (Coffea arabica). O ensaio foi conduzido em cafezal cv. Mundo Novo com idade de seis anos, espaçamento de 3,5 X 1,5 m, com uma planta/cova, no ano agrícola 1992/1993. Utilizou-se um delineamento em blocos casualizados, com 21 tratamentos e 4 repetições, cada uma contendo parcelas de cinco plantas. Os tratamentos consistiram nas aplicações dos produtos triadimenol + disulfoton 1,5% + 7,5% (26 g/cova), aldicarb 150G (10,00 g/cova), ethoprophos 100G (30,00 g/cova), phorate 5G (80,00 g/cova) e terbufos 5G (40,00 g/cova) em quatro modalidades de aplicação: aplicador costal manual Mebuki TF8; canequinha, lançando o produto para o ápice da planta; aplicador tratorizado Kamaq CK2-AG; e sulcos em meia lua, abertos manualmente, na projeção da copa. As avaliações foram realizadas aos 70, 105 e 140 dias após aplicação dos produtos, onde foram efetuadas aberturas de trincheiras de 50 X 50 X 50cm por cova, procedendo-se a contagem do número de ninfas vivas. Concluiu-se que o aplicador costal manual e canequinha revelaram-se os mais eficientes (86,0 - 93,5% e 76,8 - 86,7%, respectivamente); aplicação tratorizada e sulcos na projeção de copa tiveram sua eficiência variável com o produto utilizado; terbufos apresentou maior redução da população (98,2 - 100%) e phorate (79,6 - 99,1%) e a mistura triadimenol + disulfoton (82,3 - 97,3%) apresentaram alta eficiência, não diferindo do terbufos. Aldicarb apresentou desempenho satisfatório (68,1 - 85,0%) conforme o modo de aplicação e ethoprophos não foi eficaz quando aplicado com o aplicador costal manual (58,4%), canequinha (45,1%) e sulco (31,9%).

Do controle de constitucionalidade dos atos jurisdicionais transitados em julgado

The following study aims to verify in which hypothesis res judicata, when it comes of an unconstitutional decision, shall not prevail over Constitution. It displayed the characteristics of formal and material constitutional systems. It debated the concepts of existence, validity and efficacy of juridical rules and acts. It dissertated about the idea of Constitution s superiority and about the birth of the judicial review of constitutionality. It focused some contemporary models of this judicial review and its historical evolution in Brazil, showing its effects towards the current Constitution. It sustained that the decision given by Supremo Tribunal Federal during abstract control of rules must bind even legislative bodies, preventing them to produce the same rules previously declared unconstitutional. It held up that all parts of the decision of Supremo Tribunal Federal oblige, even the juridical arguments employed, in both diffused and concentrated reviews. It showed that, despite these models of review live together in Brazil, our constitutional system preferred the concentrated one, considering one only court over the other constitutional organs. It discussed about res judicata with the purpose of clarifying its juridical nature, its objective and subjective limits and its regulation in collective demands. It explained that the material res judicata is an effect of a decision which cannot be reviewed, which makes the law s will free of discussion, binding the contendants and avoiding that other courts, judging future demands about the same object, may decide differently. It showed how the regulation of res judicata in collective demands, in respect oh their subjective limits, is useful to demonstrate that it is not the material law who must adapt itself to res judicata as traditionally thought, but res judicata, as a warranty of juridical certainty and security, who must be shaped from the debated rule. It presented to view the main doctrinal conceptions about res judicata s review in the hypothesis of unconstitutional judgement. It concluded that the decisions forged by unconstitutional rules or interpretations reputed not compatible to the Constitution by Supremo Tribunal Federal, in spite of it can make res judicata, may be reviewed beyond the term to file a recissory claim, since while the debated law is still valid, no matter if its decision was before or after the res judicata. At the end, it asserted that, when it is not legally authorized, the judicial review of res judicata is not admissible, after the term to file a recissory claim, under the argument that there was no direct violation to the constitutional principle or rule

O controle social do judiciário: a experiência do Observatório da Justiça e Cidadania no Estado do Rio Grande do Norte

This dissertation deals with the possibility of build an effective social control of the judiciary Brazilians. The theme was bounded by a cut geographic and secular: the experience of the Center of Justice and Citizenship in the state of Rio Grande do Norte (OJC/RN), which begins formally in august 2003. The research approach and leave of experience in judicial practice and policy specific substrates to theorize about the subject. We collected documents about cases, the judicial diagnoses, reports, news material, in addition to lifting bibliographic. Therefore, it is working with about notions of a democratic state of right in the light of the Brazilian Constitution of 1988, in order to contextualize the insertion of the judicial system, by the prospect of legitimacy, which is considered by a look formal and material. It is a brief analysis of the system of official control of the judiciary (internal and external), is emphasizing its shortcomings functional and its corporate character, which suffers from poor conformation democratic. Then there is a discussion about the need to establish the social control of the judiciary, through the prism of relations of power that are locked in the judiciary, the lack of formal criteria for the guarantee of obtaining the correct judgment (laws, precedents and conscience of the judge), the problems of impunity and justice class, and from the examination of some cases, as the body of search. From this conjuncture, prepares to be an outline of shapes and the limits of social control, consonant the proposal erected in certain sectors of organized civil society, represented by the movement s social OJC. In the end, considerations are made on the legitimacy and constitutionality of OJC

Uso de morfina, xilazina e meloxicam para o controle da dor pós-operatória em cadelas submetidas à ovariossalpingo-histerectomia

Foram realizados estudos empregando-se analgésicos por via epidural e subcutânea em cadelas de diferentes raças e idades, submetidas à castração mediante celiotomia. Vinte animais foram tranquilizados e anestesiados com tiletamina-zolazepam, e aleatoriamente distribuídos em quatro grupos (n=5), de acordo com o fármaco e a via de administração. Os do grupo morfina (GM) foram submetidos à anestesia epidural no espaço lombossacro, com morfina (0,1mg/kg) associada ao cloreto de sódio a 0,9%. Aos do grupo xilazina (GX), foram administrados xilazina (0,2mg/kg) e cloreto de sódio a 0,9%. Os do grupo meloxicam (GME) receberam 0,2mg/kg do anti-inflamatório meloxicam associado ao cloreto de sódio a 0,9%, injetado pela via subcutânea. Os do grupo-controle (CG) receberam apenas cloreto de sódio a 0,9%. O volume final para as injeções epidurais foi padronizado para 0,3mL/kg. A mensuração inicial da concentração de cortisol plasmático, do ritmo cardíaco, da frequência respiratória e os parâmetros comportamentais foram registrados imediatamente antes do procedimento cirúrgico (M1). Registros adicionais foram apresentados às 2, 6, 12 e 24 horas após o procedimento cirúrgico (M2, M3, M4 e M5, respectivamente). As variáveis comportamentais foram avaliadas por meio de sinais clínicos e seus respectivos escores. em GX foram observadas depressão respiratória, bradicardia e concentração de cortisol mais alta do que o registrado no GM. A analgesia obtida pelo meloxicam foi considerada ineficiente. É possível concluir que a morfina, via epidural, promoveu menor incidência de efeitos colaterais e melhor analgesia e bem-estar animal.

O Insituto do Amicus Curiae no controle de consitucionalide brasileiro: uma abordagem à luz da efetividade do princípio do acesso à justiça

It presents a study about the control of constitutionality, its requirements and beddings. It brings, at first, notions about the concept of constitution, in its most varied aspects, as well as the systems of Control of Constitutionality. It emphasizes, considering the actual Brazilian situation, which passes through constitutional reforms and, therefore, assenting the appearance of an enormous amount of ordinary laws, the legal instability that has formed itself within the national panoram. Because of this situation, the institute of the Control of Constitutionality gains inmportancy as a way of protection of our Great Letter, against possible violations which can unfortunately happen. More ahead in the difuse control of constitutionality argues the new trend of generalization, especially after the recent reform that introduced the general repercussion as new requirement of admissibilidade of the appeal to the Brazilian Supreme Court. In the final chapter brings an analysis on the institute of amicus curiae, arguing its historical origins and its evolution, in the comparative jurisprudence, and the Brazilian right. From then is gone deep the paper of amicus curiae in the constitutionality control and, after quarrel on the difficulties of the Brazilian population to materialize its right before the judiciary, as this new institute could contribute in basic way for the materialization of the constitutional rule of access to justice

Repercussão geral e súmula vinculante: os efeitos no controle difuso

Brazil since its first republican constitution has adopted systems of laws control. The review activity was given to three state powers or functions state, Executive, Legislative and Judiciary. However, it appears that in the country along the constitutional history, has stood considerably the jurisdictional control of the most important control. Initially, back in 1891, Brazil adopted the jurisdictional control of diffuse from U.S, whose role in monitoring of standards is delivered to all organs of the judiciary, which may face a case, put on trial, ascertain whether or not the possibility of applying a law, removing its impact in case of unconstitutionality. In 1969, entered in the second legal model of judicial review, the concentrated control of constitutionality, whose inspiration comes from the positivist theory of Hans Kelsen, and was adopted by the Austrian Constitution of 1920. According to the abstract control the supervision of law is given to a Court or Constitutional Court, responsible for the analysis of the legal constitutionality independent of its application to a specific case. In Brazil the role of concentrated control was handed over exclusively to the Supreme Court, which serves as the Constitutional Court, which accumulates that function with other constitutionally provided jurisdiction. Throughout this period, from 1891 until today, Brazil has maintained a dual system of judicial control of legal constitutionality, where they coexist and harmonize the diffuse control exercised by any organ of the Judiciary, and concentrated control of competence the Supreme Court. However, one must recognize that with the advent of the Federal Constitution of 1988, the concentrated control has emerged on the national stage due to two important factors: the expansion of the legal capacity to sue and the inclusion of other ways control, besides the already known Direct Claim of Unconstitutionality. This concentrated control and projection of the Supreme Court s attempt to become a true constitutional court, led to a relative weakening of diffuse control even when performed by the Brazilian Constitutional Court. In order to become a true constitutional court, all decisions handed down by the Supreme in the exercise of constitutional jurisdiction should have the same weight and the same measure, or at least bring improvement to similar effects, once is the responsible for the final word when it comes to constitutional interpretation. Thus, the writs of certiorari and stare decisis were responsible for profound changes in the diffuse control, allowing the Supreme Court can strengthen its decisions even in the diffuse control. These two institutions have substantially changed the legal status of diffuse control, allowing an extension of the effects of decisions handed down by the Supreme Court, so that you can no longer be said that the effects of this control to restrict the disputing parties in the process

A revenda de combustível e os limites constitucionais para a sua regulação: uma análise aplicada aos aspectos concorrênciais e ao controle de preços

The gas retail represents the end of a section of the oil and natural gas derivative chain, for it is at this stage where the commercialization of those merchandises takes place towards the costumers. This process involves an enormous amount of economic agents, which reflects on an activity of great influence on the citizen's everyday. By the time of the gas retail price liberalization, in 2002, there were great expectations towards that measure, for the insertion of that segment in a competitive market was likely to create a decrease in prices. As there was not a drastic drop off in cost, the question was no longer the price itself, but, predominantly, the conduct taken by the economic agents that operate the market. Not in vain, the segment introduces a greater number of different procedures combined with the organs that compose the Brazilian System of Competition Protection. What is understood, however, is that many of these complaints are made in a lightly way, without a proper analysis of the market and its practices, that being why, in this paper, evidences the causes of these complaints and explained what, in fact, occurs in this market. Also, the organs that protect the free initiative in the sector use different methods to assess anticompetitive practices, which are counterproductive on the combat of anticompetitive practice, that being why the present paper analyzes the used methods on a critic perspective, choosing one which is believed to be the most adequate. The present work also tries to present the gas retail prices on a constitutional, free competition, free initiative and consumers defense perspective, analyzing the competition s aspects on the gas market; the shaping of the gas prices; the market boundaries; the anti-competitive practices under the gas market; and analyze the possibility, according to the defined economic standards in the constitutional text of existing a greater control or gas price indexing and/or regulation which limits the distributors and resellers profit on gas. Still, in consequence of this analysis, a study on Natal s market behavior will be developed in its competitive feature. That being said, moreover being a theoretical-descriptive study, data and statistics gathered is used, which will lead, willing to grasp an experiential study on a few aspects of the Potiguar gas retail market

Infusão contínua de lidocaína em diferentes taxas no controle de arritmias induzidas pela administração de adrenalina em cães anestesiados com isofluorano

Avaliaram-se os efeitos da infusão de diferentes doses de lidocaína sobre o ritmo cardíaco, em cães anestesiados com isofluorano que receberam doses crescentes de adrenalina. Foram utilizados 10 cães, cada qual anestesiado quatro vezes, respeitando-se um intervalo de duas semanas. A indução anestésica foi realizada com propofol, 8mg/kg, e a manutenção com isofluorano a 1,5 CAM. Os animais foram distribuídos em quatro grupos, que receberam bolus de lidocaína, 1mg/kg, seguido pela infusão de lidocaína nas taxas de 50μg/kg/h (G50), 100μg/kg/h (G100) e 200μg/kg/h (G200). O grupo-controle (GC) recebeu bolus e infusão de NaCl a 0,9%. As variáveis foram mensuradas 30 minutos após a indução, e em seguida, iniciadas as infusões. Após 10 minutos do princípio dos tratamentos, colheram-se novamente os dados e iniciou-se a infusão de adrenalina, 1μg/kg/min. em intervalos de 10 minutos, realizou-se nova colheita de dados e acrescentou-se 1μg/kg/min na taxa de infusão de adrenalina, até atingir 5μg/kg/min. Comparativamente ao GC, ocorreu redução do aparecimento de batimentos de origem não sinusal e bloqueios atrioventriculares de segundo grau nos grupos tratados com lidocaína. Concluiu-se que a associação de lidocaína à anestesia com isofluorano diminuiu o aparecimento de irregularidades no ritmo cardíaco.

Perfis do controle jurisdicional de políticas publicas: parâmetros objetivos e tutela coletiva

This paper focuses on a study of public policy jurisdictional control as some effectiveness mechanism for cultural, economical, and social fundamental rights. It investigates the juridical profile of public policies based on premises of the current (Neo)Constitutional State model and the assertion of an essentially constitutionalist Law paradigm from its genesis to its most peculiar elements, and through tormenting issues, such as: its position between Law and Politics, the difference with reflective subjective rights, and the problem of high financial costs. Once its object is identified, it moves forward into the theme itself, which is that of jurisdictional control, investigating its legitimacy based on paradigmatic judicial precedents and the facing of themes such as: current role of the Judicial Power, the splitting of state functions, administrative discretion, financial affordability, illegal omissions, and budget control. Finally, it examines, as its study central object, objective parameters for definition control, execution, and transparency of public policies, as well as identifying the most appropriate collective jurisdictional tutoring to its purposes together with some of its law process means. Therefrom, it shows new perspectives for the recent study on jurisdictional control of public policies, building foundations for the fundamental rights effectiveness
