Memórias de um palhaço: O rito de passagem de Roger Avanzi para o palhaço Picolino II

This dissertaion reflects about life's trajectory of a specific clown: Roger Avanzi, who gives animus to the clown Picolino II. The main objective is to promove reflections about the insertion of the clowns in the universe of the circus, to make us comprehend the process of formation of a clown formed in a traditional circus family. In this research, we begin of the conjecture that, through the individual memory we can think about rebuild the process of a professional's integral formation.Then, we trace the itinerary of Roger Avanzi, the clown Picolino II, think that it has possibilities, in this case, to discuss about what is a clown's formation when it come from a traditional circus family. To walk on this universe, a huge numer of authors that deeply studyed about the circus ans the clowns, like: Avanzi; Tamaoki (2004), Bolognesi (2003), Castro (2005), Pantano (2007), Ruiz (1987), Silva (1997) e Torres (1998). We bring then, a theoric base that certainly, fortifies and corroborates our thoughts and reflections about the universe of circus and the trajectory of clown's formation, with special atention to Roger Avanzi, fundamentals i studies about it and with memories like Halbwachs's (2004) and Bosi's (1994). The reflections enabled to conclude that a clown doesn't born done; it becomes in the cultural trajectory, in which all the human are inserted

À beira do leito : sentimentos de pacientes durante a passagem de plantão em Unidade de Terapia Intensiva

This study aims to understand the feelings of patients admitted to the Intensive Care Unit (ICU) that experienced a change of shift at the bedside. The change of shift is one of the routines used by nursing in their work process and of great significance for the patient; therefore, deserves careful analysis in seeking to perfect themselves for the improvement of nursing care. It is a descriptive research, with a qualitative approach. The collection of information was performed using semi-structured interview, in August and September of 2011, after authorization from the Ethics Committee of the Federal University of Rio Grande do Norte, as opinion 290/2011. The analysis, based on interviews of patients, took the humanization as the thread of investigation backed by authors who deal on the subject and the theory of the gift of Marcel Mauss that sits on drug give-receive-return. The results indicate that the change of shift at the bedside but has not configured, the content of the speech of patients interviewed, as a moment that has generated fear and anxiety, could be deduced by the expression of silence, tears and other signs during interviews, how hard it is to live this experience. Nevertheless, despite this apparent tranquility, revealed uncertainty and apprehension face the speech of professional, during the visit at the bedside, particularly when referring to their health and their neighbors. On the other hand, the indifference to the participation of the patient at the time of the visit, expressing an attitude of merely technical nature, dehumanizes the act of taking care, the essence of nursing. And, for all the patients that we understand, about the visit to the bedside, as well as the ICU, we can infer that there is suffering for them. However, we understand your feelings and revelations seeking support in the theory of Mauss's gift: the patient receives the gift (care), and imbued with a feeling of gratitude, the rewards in the form of compliments and courtesies. Precisely for this reason, we need to sharpen our sensitivity to deal about the human condition in all its vulnerability.

Potencialidade à degradação na microbacia Riacho Passagem/RN

A degradação dos recursos naturais é talvez o principal problema da região do semiárido brasileiro, e essa degradação é principalmente resultante das perdas de solo, decorrente do processo erosivo. Na busca de melhor conhecer esta problemática vem sendo empregado o processo de modelagem ambiental, cujo objetivo é identificar e propor soluções para a degradação dos solos. Nesse sentido, o trabalho aplica o modelo da Equação Universal de Perda de Solos (EUPS), desenvolvido nos Estados Unidos ao longo da década de 1950, agregado as ferramentas de geoprocessamento, informações de sensoriamento remoto e Sistemas de Informações Geográficas (SIGs). A área de estudo é a Microbacia Riacho Passagem localizada na região oeste do Estado do Rio Grande do Norte, a microbacia tem uma área de 221,7Km² e esta inserida no semiárido, região Nordeste do Brasil. A metodologia utilizada consiste: em agrupar as variáveis da EUPS no ambiente SIG utilizando imagens de satélite, levantamentos bibliográficos e trabalhos de campo. Para determinação das extensões das vertentes foi empregado o Modelo RAMPA, e para adequar a EUPS as condições da área de estudo, foram realizados ajuste através de modelos estatísticos, aperfeiçoando o trabalho e os resultados gerados pelo modelo. Ao fim do processo foi desenvolvida uma pseudo linguagem no aplicativo Linguagem Espacial para Geoprocessamento Algébrico (LEGAL) disponível no software SPRING versão 5.1.2 servindo de suporte para o processamento das informações contidas no banco de dados, base da EUPS. Os resultados demonstram que inicialmente é necessário delimitar com precisão o período seco e chuvoso, informação fundamental para a EUPS, uma vez que o trabalho busca identificar a perda de solo por erosão hídrica. O modelo RAMPA apresentou-se satisfatório e com elevado potencial de aplicação na determinação dos comprimentos de vertentes utilizando imagens de radar. Quanto ao comportamento das extensões de vertentes, na microbacia, o mesmo apresentou uma pequena variação na porção leste, maiores vertentes, área próxima a desembocadura. Após a aplicação do modelo o valor máximo de perda de solo foi 88 ton/ha.ano com núcleos localizados no NEOSSOLOS LITÓLICOS e o mínimo 0,01 ton/ha.ano localizado no domínio dos LATOSSOLOS e NEOSSOLOS FLÚVICOS. A erosão provoca diminuição do perfil de solo, principalmente nos NEOSSOLOS LITÓLICOS, resultando em alteração no balanço hídrico e conseqüentemente aumento da temperatura do solo, podendo desencadear a desertificação. Os resultados e a metodologia do presente trabalho poderão ser aplicados na busca pelo desenvolvimento sustentável, na região do semiárido brasileiro, auxiliando na compreensão do binômio uso do solo e capacidade de suporte do meio natural.

Translocação bacteriana para o pulmão na icterícia obstrutiva experimental em ratos

RESUMO: Objetivo: Tem sido demonstrado que a icterícia obstrutiva provoca depressão do sistema imunológico, mudança no padrão de colonização bacteriana dos intestinos e passagem de bactérias da luz intestinal para a circulação porta e sistêmica. Estudo experimental em ratos procurou observar a possibilidade de translocação bacteriana para os pulmões após a ligadura do colédoco. Método: Foram utilizados 20 ratos Wistar pesando de 178 a 215g, separados aleatoriamente em dois grupos iguais. Nos ratos do grupo I foi feita a ligadura do colédoco e nos do grupo II apenas a manipulação do colédoco com pinça atraumática (sham operation). No sétimo dia de observação os animais foram mortos com superdose de anestésico, sangue foi colhido para dosagem de bilirrubinas e os pulmões ressecados sob condições assépticas. Metade de cada pulmão foi homogeneizada e semeada em meios de cultura ágar McConkey e ágar sangue. A outra metade serviu para exame histopatológico –coloração hematoxilina e eosina. Os dados foram analisados pelo teste t, com significância 0,05. Resultados: revelaram bilirrubina total em média 18,7±3,6 no grupo I e 0,7±0,2 no grupo II. No grupo I foram isoladas colônias de Klebsiela sp nos pulmões de 30% dos animais e E. coli em 20%, e os escores histopatológicos atingiram a média 6,2±2,08. No grupo II não foram detectadas bactérias nos pulmões e os escores do exame histopatológico atingiram 1,8±1,16. A diferença dos dados analisados mostrou-se significativa (p<0,05). Conclusões: Concluiu-se que a icterícia obstrutiva por ligadura do colédoco em ratos provocou translocação de germes Gram-negativos para os pulmões e resultou em alterações histopatológicas significativas.

Favela não é o lugar, são as pessoas . Desconstruindo a relação entre lugar e violência no Sarney e no Japão, Natal/RN

The city is the privileged place construction of social and political life, and the gathering of social groups. Meeting place, the diversity and possibilities. But the urban universe which cities belong is not a homogeneous whole. There are spaces demarcated and valued ideologically creating antithetical images about places that are now recognized as violent or dangerous. Peripheral urban situations of unprivileged add to theprejudices to the origin of place within the neighborlyallotments José Sarney and Novo Horizonte (Japan Slum) / Natal-RN, which are reproduced in narratives of everyday life. Spatial divisions are exploited, mixed and repeated to maintain social distances through rites of separations and dichotomies such as neighborhood/joint housing, allotment/slum and the people of the high place/the people of the down place. Social categories such as buraco(hole) and cabras (goats) are evoked to interpret the world of violence and places regarded as dangerous. The prominence of hypermasculinity and perception of children and adolescents living on the outer elements are brought up to the interpretation of images evoked in interviews with residents and their neighbors

Arquitetura residencial em João Pessoa-PB a experiência moderna nos anos 1970

In the mid-1980s, the magazine Projeto published the Actual Brazilian Architecture catalogue presenting texts by Hugo Segawa and Ruth Verde Zein with a corpus of works and engaged architects of the 1960s and 1970s. To comprehend the Brazilian architectural production post-1964, in those years of the 1980s, became a significant mission to reactivate the Brazilian architectural debate weakened by the military dictatorship. In his doctoral thesis Spadoni (2003) deals with the different ways which characterizes the Brazilian architectural production of the 1970s. Marked by inventiveness, this production was in tune with the modern thinking and in the transition period between the 1970s and the 1980s it synchronized with the international debate about post-modern architecture. Considering Spadoni s doctoral thesis, this work deals with the modern experience observed in the one-family-houses built in the seventies in João Pessoa. Some modern experiences were not clear outside, to observe it, it was necessary to search for the type of experience into the spatial disposition and of the know-how constructive, because into the appearance some houses not make explicit the use of the modern language. Other observed experiences allude to the repertoire of the Brazilian period in the years 1940s-1960s, to the experience of the modern architecture in São Paulo of the 1960s, to the experiences in which the climate of the Northeastern region strongly influenced the architectural conception. We can also find in a reduced number of houses a particular experience: it refers to experiences that expose the constructive doing, which leave the material apparent and apply to the residential type the experience of the industrial pre-fabricated buildings

Efeito do estado nutricional bioquímico de retinol e alfatocoferol sobre seus níveis em lactantes

Vitamins A and E are essential nutrients in many biological processes, so that their adequate supply to the neonate is crucial. However, the bioavailability of vitamins may be limited by factors such as maternal nutritional status and the interaction between nutrients. This study aimed to investigate the effect of biochemical nutritional status of retinol and alpha-tocopherol levels in serum and colostrum. The study included 103 healthy puerperal women treated at the reference state maternity hospital (Natal-RN). Colostrum and serum samples were collected fasting in the immediate postpartum period and the analysis of retinol and alpha-tocopherol were determined by high-performance liquid chromatography. Specific cutoff points were adopted to characterize the biochemical status of vitamins A and E. For the total group of lactanting women the average concentration of retinol in serum (1.49 ± 0.4 μmol/L-1) and colostrum (2.18 ± 0.8 μmol/L-1), as well as alpha-tocopherol in serum (26.4 ± 8.0 μmol/L-1) and colostrum (26.1 ± 12.8 μmol/L-1), indicated adequate biochemical state. However, when evaluating the individual, was found a high prevalence of deficient serum (15%) and colostrum retinol (50%), and also alphatocopherol in serum (16%) and colostrum (61%). In women with serum retinol ≥ 1.05 μmol/L-1, found an inverse correlation between serum retinol and alpha-tocopherol in colostrum (p = 0.008, r = -0.28). This association was not observed in women with serum retinol <1.05 μmol/L-1. This situation demonstrates for the first time in humans that high physiological levels of serum retinol, without supplementation, can negatively influence the transfer of alpha-tocopherol in breast milk. Although the diagnosis of satisfactory nutritional status lactanting women showed high risk of subclinical deficiency of vitamins A and E from measurements made in the colostrum

Avaliação da ação bioinseticida de SBTI e vicilina de Erythrina velutina em enzimas digestivas e membrana peritrófica de larvas de Plodia interpunctella (Lepidoptera: Pyralidae)

Plodia interpunctella (Indian meal moth) is a cosmopolitan pest that attacks not only a wide range of stored grain as well other food products. Due to its economic importance several researches have focused in a method with ability to control this pest with few or no damage to the environment. The study of digestive enzymes inhibitors, lectins and chitin-binding proteins, has often been proposed as an alternative to reduce insect damage. In this study we report the major classes of digestive enzymes during larval growth in P. Interpunctella, being those proteinases actives at pH 9.5 and optimum temperature of 50 oC to both larvae of the 3rd instar and pre-pupal stage of development. In vitro and zymogram assays presented the effects of several inhibitors, such as SBTI, TLCK and PMSF to intestinal homogenate of 3rd instar larvae of 62%, 92% and 87% of inhibition and In pre-pupal stage of 87%, 62 % and 55% of inhibition, respectively. Zymograms showed inhibition of two low molecular masses protein bands by TLCK and that in presence of SBTI were retarded. These results are indicative of predominance of digestive serine proteinases in gut homogenate from Plodia interpunctella larvae. This serine proteinase was then used as a target to evaluate the effect of SBTI on larvae in in vivo assay. Effect of SBTI on mortality and larval mass was not observed at until 4% of concentration (w/w) in diets. Chitin, another target to insecticidal proteins, was observed by chemical method. Moreover, optic microscopy confirmed the presence of a peritrophic membrane. Established this target, in vivo effect of EvV, a chitin binding vicilin, evaluated during the larval development of P. interpunctella and was obtained a LD50 of 0,23% and WD50 of 0,27% to this protein. Mechanism of action was proposed through of the in vivo digestibility of EvV methodology. During the passage through the larval digestive tract was observed that EvV was susceptible to digestive enzymes and a reactive fragment, visualized by Western blotting, produced by digestion was recovered after dissociation of the peritrophic membrane. The bound of EvV to peritrophic membrane was confirmed by immunohystochemical assays that showed strong immunofluorescent signal of EvV-FITC binding and peritrophic membrane. These results are a indicative that vicilins could be utilized as potential insecticide to Plodia interpunctella and a control methods using EvV as bioinsecticide should be studied to reduce lost caused by storage insect pests

Adição de vermiculita expandida mícron em pastas de baixa densidade para cimentação de poços de petróleo

The northeastern region of Brazil has a large number of wells producing oil using a method of secondary recovery steam injection, since the oil produced in this region is essentially viscous. This recovery method puts the cement / coating on thermal cycling, due to the difference in coefficient of thermal expansion between cement and metal coating causes the appearance of cracks at this interface, allowing the passage of the annular fluid, which is associated with serious risk socioeconomic and environmental. In view of these cracks, a correction operation is required, resulting in more costs and temporary halt of production of the well. Alternatively, the oil industry has developed technology for adding new materials in cement pastes, oil well, providing high ductility and low density in order to withstand the thermo-mechanical loads generated by the injection of water vapor. In this context, vermiculite, a clay mineral found in abundance in Brazil has been applied in its expanded form in the construction industry for the manufacture of lightweight concrete with excellent insulation and noise due to its high melting point and the presence of air in their layers lamellar. Therefore, the vermiculite is used for the purpose of providing low-density cement paste and withstand high temperatures caused by steam injection. Thus, the present study compared the default folder containing cement and water with the folders with 6%, 8% and 10% vermiculite micron conducting tests of free water, rheology and compressive strength where it obtained the concentration of 8 % with the best results. Subsequently, the selected concentration, was compared with the results recommended by the API standard tests of filtered and stability. And finally, analyzed the results from tests of specific gravity and time of thickening. Before the study we were able to make a folder with a low density that can be used in cementing oil well in order to withstand the thermo-mechanical loads generated by steam injection

Estudo paramétrico da recuperação de petróleo pesado por aquecimento eletromagnético resistivo

Electrical resistive heating (ERH) is a thermal method used to improve oil recovery. It can increase oil rate and oil recovery due to temperature increase caused by electrical current passage through oil zone. ERH has some advantage compared with well-known thermal methods such as continuous steam flood, presenting low-water production. This method can be applied to reservoirs with different characteristics and initial reservoir conditions. Commercial software was used to test several cases using a semi-synthetic homogeneous reservoir with some characteristics as found in northeast Brazilian basins. It was realized a sensitivity analysis of some reservoir parameters, such as: oil zone, aquifer presence, gas cap presence and oil saturation on oil recovery and energy consumption. Then it was tested several cases studying the electrical variables considered more important in the process, such as: voltage, electrical configurations and electrodes positions. Energy optimization by electrodes voltage levels changes and electrical settings modify the intensity and the electrical current distribution in oil zone and, consequently, their influences in reservoir temperature reached at some regions. Results show which reservoir parameters were significant in order to improve oil recovery and energy requirement in for each reservoir. Most significant parameters on oil recovery and electrical energy delivered were oil thickness, presence of aquifer, presence of gas cap, voltage, electrical configuration and electrodes positions. Factors such as: connate water, water salinity and relative permeability to water at irreducible oil saturation had low influence on oil recovery but had some influence in energy requirements. It was possible to optimize energy consumption and oil recovery by electrical variables. Energy requirements can decrease by changing electrodes voltages during the process. This application can be extended to heavy oil reservoirs of high depth, such as offshore fields, where nowadays it is not applicable any conventional thermal process such as steam flooding

Análise do desempenho de um queimador infravermelho funcionando com gás liquefeito de petróleo e glicerina

The use of infrared burners in industrial applications has many advantages in terms of technical-operational, for example, uniformity in the heat supply in the form of radiation and convection, with greater control of emissions due to the passage of exhaust gases through a macro-porous ceramic bed. This paper presents an infrared burner commercial, which was adapted an experimental ejector, capable of promoting a mixture of liquefied petroleum gas (LPG) and glycerin. By varying the percentage of dual-fuel, it was evaluated the performance of the infrared burner by performing an energy balance and atmospheric emissions. It was introduced a temperature controller with thermocouple modulating two-stage (low heat / high heat), using solenoid valves for each fuel. The infrared burner has been tested and tests by varying the amount of glycerin inserted by a gravity feed system. The method of thermodynamic analysis to estimate the load was used an aluminum plate located at the exit of combustion gases and the distribution of temperatures measured by a data acquisition system which recorded real-time measurements of the thermocouples attached. The burner had a stable combustion at levels of 15, 20 and 25% of adding glycerin in mass ratio of LPG gas, increasing the supply of heat to the plate. According to data obtained showed that there was an improvement in the efficiency of the 1st Law of infrared burner with increasing addition of glycerin. The emission levels of greenhouse gases produced by combustion (CO, NOx, SO2 and HC) met the environmental limits set by resolution No. 382/2006 of CONAMA

Análise de um queimador infravermelho funcionando com combustível híbrido : GLP/Bio-óleo

Biomass is considered the largest renewable energy source that can be used in an environmentally sustainable. From the pyrolysis of biomass is possible to obtain products with higher energy density and better use properties. The liquid resultant of this process is traditionally called bio-oil. The use of infrared burners in industrial applications has many advantages in terms of technical-operational, for example, uniformity in the heat supply in the form of radiation and convection, with a greater control of emissions due to the passage of exhaust gases through a macroporous ceramic bed. This paper presents a commercial infrared burner adapted with an ejector proposed able to burn a hybrid configuration of liquefied petroleum gas (LPG) and bio-oil diluted. The dilution of bio-oil with absolute ethanol aimed to decrease the viscosity of the fluid, and improving the stability and atomization. It was introduced a temperature controller with thermocouple modulating two stages (low heat / high heat), and solenoid valves for fuels supply. The infrared burner has been tested, being the diluted bio-oil atomized, and evaluated its performance by conducting energy balance. The method of thermodynamic analysis to estimate the load was used an aluminum plate located at the exit of combustion gases and the distribution of temperatures measured by thermocouples. The dilution reduced the viscosity of the bio-oil in 75.4% and increased by 11% the lower heating value (LHV) of the same, providing a stable combustion to the burner through the atomizing with compressed air and burns combined with LPG. Injecting the hybrid fuel there was increase in the heat transfer from the plate to the environment in 21.6% and gain useful benefit of 26.7%, due to the improved in the efficiency of the 1st Law of Thermodynamics of infrared burner

Os trabalhos de amor e outras mandingas: A experiência mágico-religiosa em terreiros de umbanda

The following text addresses the magical-religious experience carried on by many individuals when they seek to solve their love, financial and health problems by means of white magic spells done by pais-de-santo e mães-de-santo (saint s father and saint s mother) from umbanda. The rites through which this seek can be detected are free love spells, troublesolving spells, and healing spell. The concept of experience, here understood as the thing which gives sense to the sense, has been the main guiding idea of the reflections here enclosed. People who seek the umbandista spells as a way of solving their daily afflictions have the opportunity of living a rich magical-religious experience in which several dimensions intersect. Among these dimensions I decided to study the performance, the knowhow and the subjetivity. Each one gave rise to the opportunity of studying a range of other themes, such as the corporeity, the gestuality, vocality, the world knowledge, the science, the secret, the emotions and the moral. The ethnographic research was carried on in the yards which are named after Dona Luiza, Pai Gledson, Pai Salviano and Dona Terezinha umbanda, all of them situated in the town of Limoeiro do Norte, Ceará

Barreiras de sobrevivência: angústias e dilemas de jovens infratores pós-institucionalização

This study critically examines the effects of public policies, implemented by Fundação Estadual da Criança e do Adolescente (FUNDAC/RN), along with adolescents of both sexes, perpetrators of illegal acts in compliance by court order, by socio-educative measures , identifying the contradictions that permeate the understanding and treatment of issue. The aim is to investigate the chances that youths have by living in Centro Educacional Pitimbu and Centro Educacional Padre. João Maria (CEDUC), to become subjects in the exercise of their citizenship. The methodology adopted is the verbal history of life (MEIHY, 2005) of youths that had life experiences in these institutions from 2002 to 2005, allowing researchers to access directly to investigated individuals, through the place where they currently reside, and enabling the reconstitution of their life story, from semi-structured interviews. The young people s statements interviewed were grouped and analyzed from the following categories of analysis: the egress and family, the school and egress, the community and egress, the egress and work, the egress and CEDUC, the egress and experience infringement. The results indicate that, despite the advances in Brazilian legislation for the sector, the actions promoted by these institutions generally would have produced innocuous and stigmatized consequences. Moreover, they show in essence that they carry on their inner contradictions which fundamentally correspond to the interests of the dominant system and a society which uses mechanisms of social policy, in addition to favoring the control and repression. And thus, while such actions remain unable to produce important changes in the conditions of existence of young people who meet by social deprivation of liberty, it is possible to say that the chances are minimal so that they become autonomous subjects in a society that, preferring their punishment, denies them, stubbornly, access to their basic rights. In theory, the researcher dialogues with authors as Foucault, Goffman, Bourdieu, Offe, Bauman, Boaventura Santos, Takeuti, Germano, Ariès, Wacquant, among others

A arte de si: uma análise da ascese nas comunidades alternativas

In this research, we studied alternative communities that promote self-care practices, as well as environmental and community care.We problematized if there are ascetical practices in these communities - understanding asceticism from Ortega (2008) and Foucault (2006, 2009, 1998), which would be a transition from one type of subjectivity to another one to be achieved through exercises on itself, in other words, the ascetic oscillates between a refused identity to another to be drawn by an art that focuses itlself.This research was conducted through the analysis of files, observations of daily practices and interviews with open questions in order to achieve reflections and thoughts of the residents of alternative communities.For our study, we chose the Alternative Community of Campina, located in the Capon Valley/Bahia; Sabiaguaba community, located in Fortaleza-CE; and the National Meeting of Alternative Communities (ENCA). The research points to ways of living that create new subjectivities, in which the subject feels responsible for taking care of themselves, others and the environment
