Antonin artaud: a crueldade pelos desenhos e autorretratos

Antonin Artaud, a name that reminds us of areas ranging from theater to poetry, linguistics to psychoanalysis, is a multipurpose name that transits as poet, painter, writer, actor, screenwriter, playwright and theater director. Artaud s route is raw material for researchers of various hues interested in a life and work that allows panning in different fields of knowledge. It raises the question of language and manipulation of signals in terms of magical forces and the relationship maintained through them with the cosmos and the divine. Artaud searches through a language of signals, gestures and objects that express themselves by objective forms and the use of words as solid objects. For him, the language of words must give way to the language of signals, whose objective aspect is what strikes us most immediately. Our work indicates the possibility of realization and recognition of the aesthetic of cruelty present in the writing drawings of artaudian s work, realizing thus, that art as a record of culture hence as double of life allows us a more critical and transforming look to the society, thinking about the aesthetics of cruelty as Artaud proposes and thinks cruelty: as appetite for life. Our dialogue held during the construction of this journey has the company, besides the one of Antonin Artaud, other authors such as Jacques Derrida, Gilles Deleuze and Felix Guatarri, among others which, during the hike and framing of this route help us to think about the aesthetics of cruelty in an Artaudian perspective

Influência das mudanças climáticas na estrutura funcional da comunidade fitoplanctônica em um reservatório da região do semiárido

The Brazilian Northeast is the most vulnerable region to climatic variability risks. For the Brazilian semi-arid is expected a reduction in the overall rates of precipitation and an increase in the number of dry days. These changes predicted by the IPCC (2007) will intensify the rainfall and droughts period that could promote the dominance of cyanobacteria, thus affecting the water quality of reservoirs, that are most used for water supply, in the semi-arid. The aim of this study was to evaluate the effects of increasing temperature combined with nutrient enrichment on the functional structure of the phytoplankton community of a mesotrophic reservoir in the semi-arid, in the worst case scenario of climate change predicted by the IPCC (2007). Two experiments were performed, one in a rainy season and another in the dry season. In the water sampled, nutrients (nitrate and orthophosphate) were added in different concentrations. The microcosms were submitted to two different temperatures, five-year average of air temperature in the reservoir (control) and 4°C above the control temperature (warming). The results of this study showed that warming and nutrient enrichment benefited mainly the functional groups of cyanobacteria. During the rainy season it was verified the increasing biomass of small functional groups of unicellular and opportunists algae such as F (colonial green algae with mucilage) and X1 (nanoplanktonic algae of eutrophic lake systems). It was also observed an increasing in total biomass, in the richness and diversity of the community. In the dry season experiment there was a greater contribution in the relative biomass of filamentous algae, with a replacement of the group S1 (non-filamentous cyanobacteria with heterocytes) for H1 (filamentous cyanobacteria with heterocytes) in nutrient- enriched treatments. Moreover, there was also loss in total biomass, species richness and diversity of the community. The effects of temperature and nutrients manipulation on phytoplankton community of reservoir Ministro João Alves provoked changes in species richness, the diversity of the community and its functional composition, being the dry period which showed the highest susceptibility to the increase in the contribution of potentially toxic cyanobacteria with heterocytes

Implicações técnicas da vacinação na resposta imune contra o vírus da febre aftosa

Na bovinocultura brasileira, a vacinação contra o vírus da Febre Aftosa (FA) é fundamental para a fase inicial de erradicação da enfermidade. Mesmo a qualidade da vacina tendo controle rígido feito pelos órgãos oficiais, restam variáveis técnicas ainda não monitoradas como manipulação, transporte e conservação pelo consumidor, dose, local e forma de aplicação que interferem na resposta imune, preocupações essas, que direcionam o presente estudo. Assim, pela pesquisa de anticorpos neutralizantes do vírus da FA em placas de microtitulação com cultivo de células BHK-21, foram determinados os títulos, calculados em logaritmo decimal (SN), em soros sanguíneos de bovinos vacinados conforme o protocolo apresentado. No primeiro grupo com 25 animais, a média de SN foi igual a 2,37 e 2,19, respectivamente, 30 e 180 dias após a vacinação, cuja vacina foi manejada por especialista com todos os cuidados técnicos recomendados. Outro grupo com 140 bovinos, distribuídos em 5 fazendas distintas, apresentou média de SN igual a 1,66 e 1,5l depois de 30 e 180 dias após a vacinação, cuja vacina foi manejada sem acompanhamento técnico e por indivíduos não especializados. Finalmente um terceiro grupo com 10 animais, que ficaram sem vacinação, apresentou média de SN igual a 0,82 e 0,81, também 30 e 180 dias após a aplicação do placebo. Assim, só os cuidados com a qualidade da vacina são insuficientes para proporcionar títulos satisfatórios que determinam proteção dos rebanhos contra o vírus da FA, uma vez que a literatura pertinente considera rebanhos com 1,52 de média do SN como tendo 50% dos animais protegidos, e com 1,70 como tendo mais de 70% de proteção, no período de até 7 meses.

Um estudo sobre a aprendizagem de alguns conceitos algébricos e geométricos

The objective of the present work was develop a study about the writing and the algebraic manipulation of symbolical expressions for perimeter and area of some convex polygons, approaching the properties of the operations and equality, extending to the obtaining of the formulas of length and area of the circle, this one starting on the formula of the perimeter and area of the regular hexagon. To do so, a module with teaching activities was elaborated based on constructive teaching. The study consisted of a methodological intervention, done by the researcher, and had as subjects students of the 8th grade of the State School Desembargador Floriano Cavalcanti, located on the city of Natal, Rio Grande do Norte. The methodological intervention was done in three stages: applying of a initial diagnostic evaluation, developing of the teaching module, and applying of the final evaluation based on the Mathematics teaching using Constructivist references. The data collected in the evaluations was presented as descriptive statistics. The results of the final diagnostic evaluation were analyzed in the qualitative point of view, using the criteria established by Richard Skemp s second theory about the comprehension of mathematical concepts. The general results about the data from the evaluations and the applying of the teaching module showed a qualitative difference in the learning of the students who participated of the intervention

Clostridium perfringens em rações e águas fornecidos a frangos de corte em granjas avícolas do interior paulista: Brasil

Através de métodos bacteriológicos convencionais, avaliou-se a contaminação por Clostridium perfringens na ração e água utilizadas na alimentação e dessedentação de frangos de corte em diferentes regiões avícolas do interior paulista. C. perfringens esteve presente em 42 e 30% das amostras de ração e águas analisadas, respectivamente. As médias das contagens foram 6,7 x 10-2UFC mL para as amostras de água e 3,69 x 10-2UFC g para as de rações. As altas freqüências e contagens de C. perfringens verificadas nas rações e nas águas podem estar associadas à falta de higiene geral na manipulação e armazenamento dos mesmos. Sugere-se o monitoramento periódico da presença de C. perfringens nestas fontes, com a finalidade de evitar tal patógeno, em vista que o mesmo pode causar um surto de enterite necrótica levando, assim a grandes prejuízos na produção avícola.

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.

Infecção do trato urinário associada à sondagem vesical numa unidade de terapia intensiva

A descriptive, quantitative approach and non-participant observation study, which was aimed at analyzing the association between knowledge and practice of inclusion and maintenance of urinary catheter by nursing professionals in the occurrence of urinary tract infection, performed in the ICU of Onofre Lopes University Hospital in Natal / RN. The original sample was composed of 42 nursing staff professional, five (5) nurses and 37 nursing technicians, 27 of them were outsourced (FUNPEC and IEL fellows) and 10 servers UFRN. Data collection was performed using two instruments, the first observation procedures used in the insertion and manipulation of indwelling urinary catheter (IUC) and the second with a questionnaire that addressed the characterization data of respondents, knowledge and conduct the insertion and manipulation of the IUC. The results were tabulated in Microsoft Excel and analyzed using SPSS software, version 15.0. We found the prevalence of institutional staff members on outsourcing - IEL and FUNPEC - (64.3%) were female (69.0%), aged 21 to 35 years (59.5%) and with mid-level education (88.1%). As to knowledge, we found that the nurses had levels of good to excellent and the nursing technicians, to regulate the poor. The nurses made a mistake when choosing IUC (40.0%) and washing hands (30.0%) and technicians on hand washing (74.4%) and the contents of the tray (34.7%). In relation to the conduct of insertion of IUC, the nurses made a mistake when choosing SVD (66.7%) and washing hands (57.1%). Regarding the handling of IUC/drainage system, the technicians were wrong more about washing their hands (56.0%). Analyzing the misconduct to the categorization of knowledge, we saw that the nursing staff who had missed more had inadequate knowledge (ρ = 0.001). At the end we found the risk of a patient to acquire UTI is higher in two and a half times when there is a large number of mismatches, patient spends more time using the IUC and hospitalized in the ICU. As regards the study hypotheses, we accept the alternative hypothesis and reject the null hypothesis proposed at the start of this research, where the number of gaps in knowledge and behavior increases the incidence of urinary tract infection.

A Produção mais Limpa como ferramenta em busca da sustentabilidade empresarial: um estudo de múltiplos casos em empresas do Estado do Rio Grande do Norte

This study aimed to assess the Cleaner Production CP as corporate sustainable tool, through the multiple case studies within companies from Rio Grande do Norte State. In order to achieve this goal a research methodology approach was set. The initial stage of the research methodology was based on a literature review on which it was observed that the CP can be linked with corporate sustainable once it prevents pollution and reduces the operational risks among employees, community and environment. In addition, CP can useful for companies position within competitive position as well as being applied to process, products and services. In order to observe these factors, CP was used within food industry (Company 1), textile industry (Company 2) and in a car dealer (Company 3). Regarding the results, Company 1 changed its raw material as well as implementing housekeeping (control use of water, energy and condensed milk). In Company 2, it was observed the three levels of CP. In other words, housekeeping (e.g. cutting process and manipulation of chemical products), changing technology (high pressure washing machine) and internal and external recycling. In addition, Company 3 considered only level 3 external recycling. As consequence, it was observed that can be applied either within industry as well as service sector. Unfortunately, it was not possible to observe any social gains on a monetary basis. This is due to limitations of the CP methodology and study complexity. Therefore, it was observed improvements regarding to social, environmental and economic areas. Nevertheless, it is necessary more commitment from top level management in order to consider CP like effective sustainable tool

Produção de metano entérico em pastagens tropicais

Na presente revisão, buscou-se apresentar os principais impactos ambientais causados pela pecuária, sobretudo, em relação às emissões de gases efeito estufa (GEE). Além disso, buscou-se apresentar possíveis formas de mitigar essas externalidades. A criação de bovinos, no Brasil, acontece de forma extensiva, muitas vezes em áreas com pastagem degradada e, portanto, de baixa produtividade. Isso possibilita à atividade uma oportunidade de redução do impacto causado ao meio ambiente, uma vez que ações tomadas, no sentido de melhorar o rendimento animal, devem resultar em um menor consumo de recursos naturais (terra e água) e maior eficiência do sistema digestivo animal. Os principais problemas apontados pelos pesquisadores, no que tange à pecuária extensiva, são o metano emitido pela fermentação entérica dos ruminantes, o óxido nitroso emitido pelos dejetos dos animais em pastejo e o dióxido de carbono trocado pelo solo e vegetação. Muitos fatores influenciam a produção de CH4 entérico dos ruminantes, inclusive o tipo de carboidrato fermentado, o sistema digestivo do animal, a quantidade e o tipo de alimentos consumidos. Diante do exposto, pesquisadores têm desenvolvido tecnologias para reduzir a emissão de metano, através da melhoria das práticas de manejo alimentar, manipulação ruminal, por meio de suplementação com monensina, lipídios, ácidos orgânicos e compostos de plantas. Outras estratégias de redução de metano que foram investigadas são: defaunação e vacinas, que buscam inibir micro-organismos metanogênicos e a metanogênese. Assim, a busca por sistemas de produção eficientes tem sido uma das perspectivas da pecuária mundial para reduzir a emissão de poluentes e intensificar a produção animal.

Avaliação econômica das perdas de banana no mercado varejista: um estudo de caso

O objetivo do presente estudo foi a determinação das perdas físicas e econômicas de banana em diferentes equipamentos varejistas na Cidade de Botucatu - SP e suas possíveis causas. Os equipamentos foram sorteados aleatoriamente. As informações foram coletadas através da aplicação de questionário para a determinação das perdas de três variedades de banana. O resultado mostrou perda global de 39 toneladas, correspondente a 11,1% da quantidade comercializada, sendo 10,5% em supermercados, 15,0% em quitandas/sacolões e 10,6% em feiras livres. O valor total das perdas anuais atingiu R$ 35.038,00, em valores de maio de 2002. A manipulação excessiva do cliente, excedente de oferta, uso de embalagem inadequada e baixa qualidade da fruta foram as principais causas de perdas. Conclui-se pela necessidade de conscientização do cliente, do uso de embalagens plásticas e de cuidados no manuseio da fruta durante toda pós-colheita.

Mecanismos de segurança para um sistema cooperativo de armazenamento de arquivos baseado em P2P

Previous works have studied the characteristics and peculiarities of P2P networks, especially security information aspects. Most works, in some way, deal with the sharing of resources and, in particular, the storage of files. This work complements previous studies and adds new definitions relating to this kind of systems. A system for safe storage of files (SAS-P2P) was specified and built, based on P2P technology, using the JXTA platform. This system uses standard X.509 and PKCS # 12 digital certificates, issued and managed by a public key infrastructure, which was also specified and developed based on P2P technology (PKIX-P2P). The information is stored in a special file with XML format which is especially prepared, facilitating handling and interoperability among applications. The intention of developing the SAS-P2P system was to offer a complementary service for Giga Natal network users, through which the participants in this network can collaboratively build a shared storage area, with important security features such as availability, confidentiality, authenticity and fault tolerance. Besides the specification, development of prototypes and testing of the SAS-P2P system, tests of the PKIX-P2P Manager module were also performed, in order to determine its fault tolerance and the effective calculation of the reputation of the certifying authorities participating in the system

SAMVC sistema de autoria de museus virtuais colaborativos

The use of graphical objects three-dimensional (3D) multimedia applications is gaining more space in the media. Networks with high transmission rates, computers with large processing and graphics boost and popularize such three-dimensional applications. The areas of 3D applications ranging from military applications, entertainment applications geared up for education. Within the applications related to education, we highlight the applications that create virtual copies of cultural spaces such as museums. Through this copy, you can virtually visit a museum, see other users, communicate, exchange information on works, etc. Thereby allowing the visit museums physically distant remote users. A major problem of such virtual environments is its update. By dealing with various media (text, images, sounds, and 3D models), its subsequent handling and update on a virtual environment requires staff with specialized knowledge. Speaking of museums, they hardly have people on your team with this profile. Inside the GT-MV (Grupo de Trabalho de Museus Virtuais), funded by RNP (Rede Nacional de Ensino e Pesquisa) propose a portal for registration, amendment and seen collaborative virtual museums of Brazil. The update, be it related to work or physical space, a system with a national scale like this, would be impossible if done only by the project team. Within this scenario, we propose the modeling and implementation of a tool that allows editing of virtual spaces in an easy and intuitive as compared with available tools. Within the context of GT-MV, we apply the SAMVC (Sistema de Autoria de Museus Virtuais Colaborativos) to museums where curators build the museum from a 3D floor plan (2D). The system, from these twodimensional information, recreates the equivalent in three dimensions. With this, through little or no training, team members from each museum may be responsible for updating the system

Sistema Especialista para Supressão Online de Alarmes em Processos Industriais

Operating industrial processes is becoming more complex each day, and one of the factors that contribute to this growth in complexity is the integration of new technologies and smart solutions employed in the industry, such as the decision support systems. In this regard, this dissertation aims to develop a decision support system based on an computational tool called expert system. The main goal is to turn operation more reliable and secure while maximizing the amount of relevant information to each situation by using an expert system based on rules designed for a particular area of expertise. For the modeling of such rules has been proposed a high-level environment, which allows the creation and manipulation of rules in an easier way through visual programming. Despite its wide range of possible applications, this dissertation focuses only in the context of real-time filtering of alarms during the operation, properly validated in a case study based on a real scenario occurred in an industrial plant of an oil and gas refinery

Controle automático para injeção otimizada de gás em poços de petróleo equipados para funcionamento com gás lift contínuo

The continuous gas lift method is the main artificial lifting method used in the oil industry for submarine wells, due to its robustness and the large range of flow rate that the well might operate. Nowadays, there is a huge amount of wells producing under this mechanism. This method of elevation has a slow dynamics due to the transients and a correlation between the injected gas rate and the of produced oil rate. Electronics controllers have been used to adjust many parameters of the oil wells and also to improve the efficiency of the gas lift injection system. This paper presents a intelligent control system applied to continuous gas injection in wells, based in production s rules, that has the target of keeping the wells producing during the maximum period of time, in its best operational condition, and doing automatically all necessary adjustments when occurs some disturbance in the system. The author also describes the application of the intelligent control system as a tool to control the flow pressure in the botton of the well (Pwf). In this case, the control system actuates in the surface control valve
