A construction como método concretizador de direitos fundamentais: aplicação na jurisdição constitucional brasileira

The way of organization of the constitutional jurisdiction implies the possibility to extend the democratization of the same one in function of the popular participation in the active legitimacy to constitutional process (procedimentalist model) e, at the same time, to assure technical viable decisions fast and to the complex problems of the constitucional law (substancialist model). The comparison with the constitutional jurisdiction of U.S.A. becomes interesting from the knowledge of the wide power to decide experience of Supreme the Court that for a methodology of construction of rights and not simply of interpretation of the Constitution, brought up to date and reconstructed throughout its historical evolution the direction of the norms of basic rights and the North American principles constitutional. Construction while constitutional hermeneutic method of substancialist matrix works with techniques as the measurement of principles, the protection of interests of minorities and the entailing of the basic rights with values politicians, what it can be brought to evidence of the Brazilian constitutional jurisdiction in order to improve the construction of basic rights that comes being carried through for the judicial ativism in control of the diffuse and abstract constitutionality. To define the limits of construction is to search, on the other hand, a dialogue with the procedimentalists thesis, aiming at the widening of the participation of the citizen in the construction of the basic rights for the constitutional process and to argue forms of the society to evaluate the pronounced decisions activist in the controls diffuse and abstract of constitutionality

O discurso ideológico no método reflets-Brésil

Cette étude vise à identifier, décrire et comprendre, le discours idéologique de la méthode Reflets-Brésil. L'étude, a été subventionnée en partie par une analyze des recommandations brésiliennes, et européennes, sur l'enseignement des langues étrangères, et pour la reflexion sur le matériel d'enseignement des langues étrangères, proposées respectivement par Alain Choppin et Christian Puren, et d'autre part, trouvé appui théorique, de la proposition de John B. Thompson en ce qui concerne les concepts de la culture et l'idéologie. La recherche a été de nature qualitative, sur la base des idées de Norman Fairclough sur l'analyse critique du discours, et a été organisé autour de l'hypothèse que la méthode Reflets-Brésil, tandis que un produit de la industrie europeane du livre, adaptée pour le public brésilien, traduit le discours idéologique, malgré les recommandations brésilien en matière d'éducation et le développement des manuels scolaires. Dans l'étude, il a été conclu par la véracité de l'hypothèse. La méthode Méthode Reflets-Brésil, non seulement peut être comprise comme un véhicule idéologique, mais ne prévoit pas dans sa proposition pour l'enseignement des langues étrangères, un espace de réflexion qui peuvent conduire à une reconstruction de discours critique et / ou pratiques liées à l'enseignement du français comme langue étrangère

Efeito da técnica de curtimento e do método utilizado para remoção da pele da tilápia-do-nilo sobre as características de resistência do couro

Um estudo foi realizado com o objetivo de avaliar os efeitos do método de remoção da pele do filé (com alicate e com máquina) e da técnica de curtimento (com ou sem sais de cromo, bioleather) sobre a resistência da pele de tilápia-do-nilo (Oreochromis niloticus). Foram retiradas as peles de 40 tilápias (450 g), 20 com uso de alicates e 20 com auxílio de máquina. Após o curtimento e a retirada dos corpos-de-prova, as peles foram encaminhadas a um laboratório aclimatizado (23ºC e 50% de umidade relativa do ar) para realização dos testes de resistência em dinamômetro EMIC, com velocidade de afastamento entre cargas de 100 ± 20 mm/mm. O método de retirada da pele do filé não afetou os resultados dos testes de tração e rasgamento progressivo. A pele retirada com a máquina apresentou elongação superior (88,48%) à removida com alicate (71,09%). Peles curtidas com sais de cromo (25,54 N/mm; 12,18 N/mm²) foram mais resistentes que as curtidas sem sais de cromo (bioleather) (13,11 N/mm; 9,89 N/mm²). Peles curtidas por estas técnicas (com cromo e bioleather) podem ser utilizadas na confecção de vestuários, pois as médias dos testes de tração, alongamento e rasgamento progressivo foram superiores a 9,80 N/mm², 60% e 14,72 N/mm, respectivamente, valores mínimos recomendados para couros curtidos ao cromo.

Avaliação de método digital para análise do índice funcional do ciático em ratos

This work aimed to study the reproduction and description of technique for digital sampling images during rats gait and determination of the sciatic functional index (SFI), through a glass walkway to obtain shoots with a digital camera. After controlled injury by strangulation of sciatic nerve, with 3mm of length, during 30 seconds, using hemostatic forceps, a group of 32 rats was performed 24 hours before the lesion which served as control and 24 hours, 7, 14 and 21 days after injury. The tests consisted in the filming and shooting each animal in order to observe the view from below (by a mirror to 45 degrees) and subsequently analyzed using the IMAGE-J program. Measures were taken from the lengths of the legs (right and left), and the distance between the ankle. In the analysis of IFC, values close to zero (0) suggest that the function of the sciatic nerve is still preserved and values coming from "less one hundred" (-100) indicate total loss of function. It was verified in this study that 24 hours before surgery the average SFI was -7.07 +/- 7.88 and 24 hours after injury these values rose to an average of -77.95 +/- 13.81, being about 10 times larger, where 78% of the animals showed 60 to 100% of functional loss in motor activity, demonstrated by the gradual recovery over the days analyzed, confirming the accuracy and effectiveness of the proposed methodology. These results suggest that studies can be conducted to simplify and reduce costs using the technique for digital images of footprints during rats gait in the laboratory.

Seletividade de herbicidas: I - utilização do método de testemunhas pareadas em experimento com cana-de-açúcar

Este trabalho objetivou comparar a precisão experimental dos delineamentos em blocos casualizados e blocos casualizados com testemunhas pareadas na avaliação da seletividade de herbicidas em soqueira de cana-de-açúcar de terceiro corte, cultivar RB835089. Os delineamentos utilizados foram o de blocos casualizados convencional e o de blocos casualizados com testemunhas pareadas, com quatro repetições. Os tratamentos foram diuron + hexazinone, azafenidin + hexazinone, metribuzin e isoxaflutole e testemunha capinada. Avaliaram-se na cana-de-açúcar a altura, o estande, o rendimento de colmos e o ATR (Açúcar Teórico Recuperável). O delineamento em blocos casualizados com testemunhas pareadas foi mais eficaz que aquele com testemunha tradicional. Constatou-se também que, para comparação das médias dos tratamentos, o teste t foi mais sensível que o teste de Tukey, pois apresentou, com maior precisão experimental, mais tratamentos com diferenças em relação à testemunha.

Método alternativo para submeter sementes de amendoim à solução de tetrazólio

A técnica para a determinação da viabilidade de sementes de amendoim por meio do tetrazólio (TZ) é, atualmente, aquela pela qual as sementes, após embebição em água, têm o tegumento removido. A seguir as sementes são, em grupo, imersas na solução de TZ. Essa técnica dificulta o contato entre os tecidos das faces internas dos cotilédones e a solução de TZ em virtude de que o período prévio de embebição em água não é suficiente para que os cotilédones das sementes de amendoim se separem. Assim, o acesso da solução de TZ aos tecidos das faces internas dos cotilédones e ao próprio eixo embrionário, que fica entre as duas faces cotiledonares internas, é consideravelmente dificultado. Na suposição de que este procedimento levaria a resultados de testes de TZ que se correlacionam mal com o desempenho germinativo das sementes no campo, tentou-se uma nova técnica pela qual as sementes, após a embebição em água, além de terem o tegumento removido, são manualmente separadas em seus cotilédones, com o eixo embrionário ligado a um deles, e os cotilédones de uma determinada semente, agora separados, imersos na solução de TZ contida em uma célula individual de uma bandeja de PVC. A hipótese aqui formulada mostrou-se correta : a técnica alternativa de submissão das sementes de amendoim à solução de tetrazólio permitiu a obtenção de resultados que, comparados com os da técnica convencional, refletiram de modo mais preciso o desempenho germinativo das sementes no campo.

Método de colheita e superação de dormência na qualidade fisiológica de sementes de Cassia ferruginea

The harvesting method of fruits of tree species should be adequate to obtain seeds of maximum physiological quality. When present, the dormancy of Cassia ferruginea seeds is due to seed coat impermeability to water. This research work viewed to find the best methods both for the harvesting and for the breaking of dormancy of seeds of that species. The experiment was conducted during two years. In the first, fruits shed from the mother plant and laying on the ground were picked and their seeds submitted to the following treatments: 1. control, 2. mechanical scarification of the seeds with sandpaper no. 220, 3. hot water for 5 minutes (initial and final temperatures of 82 and 69 degrees C, respectively), 4. hot water for 15 minutes (initial and final temperatures of 82 and 51 degrees C, respectively), 5. chemical scarification with H2SO4 (95%) for 20, 30, 40, 50, 60, 70, and 80 minutes. In the second year, seeds were submitted to treatments 2, 3, and 4 whereas acid scarification was applied for 30, 45, and 60 minutes. The results showed that seeds picked from the ground and those taken directly from the mother plant differ in their response to the dormancy breaking procedure. The results also showed that the seeds picked from the ground are better than those harvested directly from the plant and that, when dormant, the best results are attained when seeds are either submitted to mechanical scarification or chemical scarification with sulfuric acid for periods between 30 and 60 minutes.

Aplicações da tomografia de ressonância magnética nuclear como método não-destrutivo para avaliar os efeitos de injúrias mecânicas em goiabas 'Paluma' e 'Pedro Sato'

Objetivou-se determinar o potencial do uso da tomografia de ressonância magnética, como método não-destrutivo, para avaliar os efeitos das injúrias mecânicas em goiabas. Foram utilizados frutos no estádio de maturação de vez das cultivares Paluma e Pedro Sato. Na injúria por impacto, os frutos foram deixados cair, em queda livre, de uma altura de 1,20 m, sofrendo dois impactos, em lados opostos de sua porção equatorial. Na injúria por compressão, os frutos foram submetidos a um peso de 29,4 N, por 15 minutos. Para a injúria por corte, foram efetuados dois cortes, no sentido longitudinal dos frutos, de exatamente 30 mm de comprimento por 2 mm de profundidade. Os frutos injuriados foram armazenados sob condições de ambiente (22 ± 2 °C e 40 %UR). Foram realizadas análises com tomógrafo de ressonância magnética Varian Inova de 2 Tesla. As imagens foram obtidas a partir da detecção dos prótons de hidrogênio (¹H). Para cada fruto, foram obtidos tomogramas simétricos a partir do centro do fruto. A tomografia de ressonância magnética nuclear mostrou-se uma ferramenta eficaz na detecção de injúrias internas de frutos. O estresse físico causado pelo impacto produziu um colapso interno nos lóculos desses frutos (internal bruising), levando à perda da integridade celular e a conseqüente liquefação dos tecidos placentários. A cultivar Pedro Sato mostrou uma suscetibilidade maior à injúria por impacto que a 'Paluma'. A injúria por compressão tornou-se mais evidente no pericarpo externo do fruto, de ambas as cultivares. A injúria por corte levou a lignificação dos tecidos no local injuriado e deformações superficiais devido à perda acentuada de matéria fresca no local da lesão, evidentes no sexto dia de avaliação.

Método simples e acessível para determinar amônia liberada pela cama aviária

A amônia é um gás altamente irritante e causador de estresse às aves confinadas, o que leva à perda de peso, podendo até causar a morte. Por esse motivo, existe grande interesse em se determinar a quantidade de amônia liberada por diferentes camas aviárias e de diferentes condições, bem como os fatores que influenciam a produção desta substância. Assim, idealizou-se o presente trabalho com o objetivo de desenvolver e padronizar uma metodologia simples, acessível, exeqüível para avaliar camas de frangos submetidas a diferentes condições (diferentes tratamentos, tempos de confinamento e temperatura) e capaz de determinar a potencialidade da liberação de amônia pela cama de frangos nos galpões. A metodologia baseou-se na adaptação do método da microdifusão, que consta da incubação da cama em um frasco de vidro com capacidade de 500 mL. Sobre a superfície do material incubado coloca-se um béquer de 50 mL contendo 10 mL de solução de ácido bórico 2% (m/v) para fixar a amônia exalada pela cama aviária. Esse sistema é fechado e incubado por 15 horas a 30°C e, após, a solução fixadora é retirada e titulada com ácido sulfúrico 0,05 N, usando como indicador uma mistura de verde de bromocresol e alaranjado de metila. O método proposto apresenta precisão para ser usado em experimentos e utiliza material barato e reagentes facilmente encontrados nos laboratórios.

Análise não-linear de treliças pelo método dos elementos finitos posicional

This work presents the positional nonlinear geometric formulation for trusses using different strain measures. The positional formulation presents an alternative approach for nonlinear problems. This formulation considers nodal positions as variables of the nonlinear system instead of displacements (widely found in literature). The work also describes the arc-length method used for tracing equilibrium paths with snap-through and snap-back. Numerical applications for trusses already established in the literature and comparisons with other studies are provided to prove the accuracy of the proposed formulation

Análise dos indicadores de qualidade versus taxa de abandono utilizando método de regressão múltipla para serviço de banda larga

Telecommunication is one of the most dynamic and strategic areas in the world. Many technological innovations has modified the way information is exchanged. Information and knowledge are now shared in networks. Broadband Internet is the new way of sharing contents and information. This dissertation deals with performance indicators related to maintenance services of telecommunications networks and uses models of multivariate regression to estimate churn, which is the loss of customers to other companies. In a competitive environment, telecommunications companies have devised strategies to minimize the loss of customers. Loosing customers presents a higher cost than obtaining new ones. Corporations have plenty of data stored in a diversity of databases. Usually the data are not explored properly. This work uses the Knowledge Discovery in Databases (KDD) to establish rules and new models to explain how churn, as a dependent variable, are related to a diversity of service indicators, such as time to deploy the service (in hours), time to repair (in hours), and so on. Extraction of meaningful knowledge is, in many cases, a challenge. Models were tested and statistically analyzed. The work also shows results that allows the analysis and identification of which quality services indicators influence the churn. Actions are also proposed to solve, at least in part, this problem

There for there will be a greater productivity and quality of the under taking such as costumer s satisfaction

A oficina como método de desenvolvimento de projeto do produto aplicado à atividade jangadeira de Ponta Negra Natal-RN

The jangadas (brazilian fishing rafts) are rudimentary artisanal vessels intrinsic to the Northeast of Brazil. The fishery with jangadas is highly representative in the State of Rio Grande do Norte, and source of income for many families in addition to being a strong cultural icon. Is still alive despite the difficulties, bringing the history and customs of the fishermen and their people. However, is in process of extinction due to factors such as the low profitability of the activity, tourism and urbanization. From the understanding of activity involving their context and circumstances, based on identified problems regarding the conditions of use of jangadas as the unpredictability, the risk of accidents, poor working conditions, hygiene and housing, this dissertation aims to: analyzing the design of the jangada on the beach of Ponta Negra and its relationship with the activity in relation to health, safety, productivity and environment, and from such assessments, together with the results achieved during the workshops of the project, proposing a cart to move the raft, adapted to the local fisherman activity studied. To perform analysis of jangadeira activity, we used a methodology based on ergonomic work analysis - AET (WISNER, 1987; GUÈRIN, 2001; VIDAL, 2008, SALDANHA, 2004 and Carvalho, 2005). For data collection were used observational and interaction methods as a conversational action, verbalizations, photographs and video. It is emphasized that the search for solutions appropriate to the jangadeira activity was possible through the collaboration of several people, not just an informational level and understanding during the work activity, but effectively contributing to the making decisions

Aplicação do método de análise hierárquica na tomada de decisão para adoção de computação em nuvem: um estudo de caso na federação das indústrias do RN

The progresses of the Internet and telecommunications have been changing the concepts of Information Technology IT, especially with regard to outsourcing services, where organizations seek cost-cutting and a better focus on the business. Along with the development of that outsourcing, a new model named Cloud Computing (CC) evolved. It proposes to migrate to the Internet both data processing and information storing. Among the key points of Cloud Computing are included cost-cutting, benefits, risks and the IT paradigms changes. Nonetheless, the adoption of that model brings forth some difficulties to decision-making, by IT managers, mainly with regard to which solutions may go to the cloud, and which service providers are more appropriate to the Organization s reality. The research has as its overall aim to apply the AHP Method (Analytic Hierarchic Process) to decision-making in Cloud Computing. There to, the utilized methodology was the exploratory kind and a study of case applied to a nationwide organization (Federation of Industries of RN). The data collection was performed through two structured questionnaires answered electronically by IT technicians, and the company s Board of Directors. The analysis of the data was carried out in a qualitative and comparative way, and we utilized the software to AHP method called Web-Hipre. The results we obtained found the importance of applying the AHP method in decision-making towards the adoption of Cloud Computing, mainly because on the occasion the research was carried out the studied company already showed interest and necessity in adopting CC, considering the internal problems with infrastructure and availability of information that the company faces nowadays. The organization sought to adopt CC, however, it had doubt regarding the cloud model and which service provider would better meet their real necessities. The application of the AHP, then, worked as a guiding tool to the choice of the best alternative, which points out the Hybrid Cloud as the ideal choice to start off in Cloud Computing. Considering the following aspects: the layer of Infrastructure as a Service IaaS (Processing and Storage) must stay partly on the Public Cloud and partly in the Private Cloud; the layer of Platform as a Service PaaS (Software Developing and Testing) had preference for the Private Cloud, and the layer of Software as a Service - SaaS (Emails/Applications) divided into emails to the Public Cloud and applications to the Private Cloud. The research also identified the important factors to hiring a Cloud Computing provider
