Resumo Em busca de tratamento para doenças resultantes de acometimento por espíritos, os Karajá, povo indígena centro-brasileiro, recorrem hoje, além de seus próprios xamãs, a xamãs de outras etnias e curandeiros regionais, bem como a sua fé em Deus. E todos esses curadores, a despeito de seus diferentes conhecimentos e técnicas, são considerados igualmente xamãs. Os médicos não indígenas, em contraste, não podem curar esses adoecimentos, e a esses especialistas só se recorre para tratar as ‘doenças de branco’. A diferença marcada entre doenças e especialistas, no último caso, contrasta com o regime de comunicação absoluta no primeiro. É a essa diferença que o artigo se dedica. Dialogando com a antropologia da saúde, por um lado, e com a questão da religião, por outro, proponho que o que permite que curadores de origens diversas tratem pessoas enfeitiçadas, diferentemente dos médicos, é o fato de que o xamanismo atualiza o regime de diferença infinita, ou de transparência absoluta, dos tempos primordiais. espíritos Karajá centrobrasileiro, centrobrasileiro centro brasileiro, brasileiro centro-brasileiro hoje regionais Deus técnicas indígenas contraste adoecimentos branco. branco . branco’ caso primeiro dedica saúde lado religião outro enfeitiçadas infinita primordiais

Abstract Today as they seek treatment for diseases that result from being affected by spirits, the Karajá, a Central Brazilian indigenous people, turn to their own shamans, shamans from other indigenous groups, regional healers, as well as their faith in God. All of these healers, despite their different knowledges and techniques, are equally considered shamans, while non-indigenous doctors cannot cure these illnesses and are only sought out to treat ‘white people’s diseases’. This marked difference between diseases and doctors contrasts with the regime of absolute communication for healing spirit ailments, and is the subject of this analysis. In dialog with the anthropology of health on one hand and the question of religion on the other, I argue that what allows healers from different origins to treat bewitched persons (unlike doctors) is the fact that shamanism actualizes the regime of infinite difference or absolute transparency from primordial times into the present day. spirits Karajá people groups God techniques nonindigenous non white peoples s diseases. . diseases’ ailments analysis unlike day

Abstract Polyvinylidene fluoride (PVDF) is a versatile and low-cost polymer with high biocompatibility, mechanical strength, chemical resistance, thermal stability, and ferroelectricity. This material has been widely used in many applications, ranging from membranes to electronic devices. In this study, self-supporting, flexible, and lightweight PVDF films were prepared by an evaporation route using a low-toxicity solvent (dimethyl sulfoxide – DMSO). Graphene oxide (GO) and anatase titania (TiO2) were incorporated into the PVDF after preparing DMSO-based suspensions of these materials. The prepared materials were examined in terms of their structural, electrical, and wetting properties before and after exposure to near ultraviolet (UV-A) light. Substantial structural changes took place after incorporating GO and TiO2 into PVDF. Such modifications were accompanied by dramatic changes in the wetting and electrical properties of the PVDF. UV-A light caused the formation of surface defects on PVDF and GO films. In addition, it promoted the photoreduction of GO into reduced graphene oxide (rGO). Composites containing TiO2 showed high resistance to UV-A light, probably because titania particles absorb the incoming photons and shield the polymer matrix. This study provides new insights into the synthesis and characterization of PVDF/TiO2/GO composite films, which may be useful for many applications, including flexible electronics, solar cells, and biomedical devices.

Resumo Objetivo Avaliar a qualidade radiográfica de tratamentos endodônticos e suas respectivas restaurações coronárias, correlacionando-os ao status periapical. Material e método A qualidade da obturação de quatrocentos e dezesseis dentes foi criteriosamente avaliada em três parâmetros radiográficos: i) limite apical, ii) homogeneidade e iii) conicidade, sendo E0, E1 e E2. E0 e E1 corresponderam a acentuado e suave desvio da normalidade, respectivamente; enquanto E2 correspondeu ao padrão-ouro. Em função da combinação dos escores atribuídos, a obturação foi classificada em perfeita (PF), com três escores E2; satisfatória (ST), com dois escores E2; ou deficiente (DF), com um ou nenhum escore E2. Além disso, o status periapical foi considerado como periodonto sadio; espessamento do ligamento periodontal e presença de periodontite apical. Restaurações coronárias foram classificadas quanto à presença e tipo de restauração. As associações entre as variáveis foram analisadas através do teste de Correlação de Spearman (p<0.05). Resultado Duzentos e vinte e um dentes apresentaram obturação DF (53.1%). O limite apical foi o parâmetro com maior número de E0, perfazendo 38,94% dos escores atribuídos. Individualmente, os parâmetros observados não apresentaram associação estatisticamente significativa com o status periapical (p>0.05); entretanto, o mesmo associou-se significativamente com a qualidade geral da obturação (p=0.021). Conclusão As obturações apresentaram baixo padrão de qualidade, sendo o parâmetro mais crítico, influenciando o status periapical de toda a amostra. correlacionandoos correlacionando radiográficos i ii iii conicidade E normalidade respectivamente padrãoouro. padrãoouro ouro. ouro padrão-ouro atribuídos PF, PF , (PF) ST, ST (ST) DF, (DF) disso sadio restauração p<0.05. p005 p p<0.05 . 0 05 (p<0.05) 53.1%. 531 53.1% 53 1 (53.1%) 3894 38 94 38,94 Individualmente p>0.05 (p>0.05) entretanto associouse associou se p=0.021. p0021 p=0.021 021 (p=0.021) crítico amostra (PF (ST (DF p00 p<0.0 (p<0.05 53.1 5 (53.1% 389 3 9 38,9 p>0.0 (p>0.05 p002 p=0.02 02 (p=0.021 p0 p<0.

Abstract Objective To evaluate the radiographic quality of endodontic treatments and their respective coronal restorations, correlating it with periapical status. Material and method The root filling quality of four hundred and sixteen teeth was carefully evaluated regarding three radiographic parameters: i) apical extension, ii) homogeneity and iii) taper, being E0, E1 and E2. E0 and E1 corresponding to sharp and mild deviation from normality, respectively; while E2 corresponding to the gold standard. Due to the combination of the assigned scores, filling was classified as perfect (PF), with three E2 scores; satisfactory (ST), with two E2 scores; or deficient (DF), with one or no E2 score. In addition, periapical status was considered to be a healthy periodontium; thickening of the periodontal ligament and presence of apical periodontitis. Coronary restorations were classified according to the presence and type of restoration. Associations between variables were analyzed using Spearman's Correlation test (p<0.05). Result Two hundred and twenty-one teeth had DF filling (53.1%). The apical extension was the parameter with the highest number of E0, accounting for 38.94% of assigned scores. Individually, the observed parameters did not show statistically significant association with periapical status (p>0.05); however, it was significantly associated with the general filling quality (p=0.021). Conclusion Fillings presented low quality standard, being the most critical parameter, negatively influencing the periapical status of the entire sample. i ii iii taper E normality respectively standard scores PF, PF , (PF) ST, ST (ST) DF, (DF) score addition periodontium periodontitis restoration Spearmans Spearman s p<0.05. p005 p p<0.05 . 0 05 (p<0.05) twentyone twenty 53.1%. 531 53.1% 53 1 (53.1%) 3894 38 94 38.94 Individually p>0.05 (p>0.05) however p=0.021. p0021 p=0.021 021 (p=0.021) sample (PF (ST (DF p00 p<0.0 (p<0.05 53.1 5 (53.1% 389 3 9 38.9 p>0.0 (p>0.05 p002 p=0.02 02 (p=0.021 p0 p<0.

In this study, scaffolds whose main phase is an icosahedral quasicrystal (i-QC) were prepared for the first time by dynamic freeze-casting. Two different metal powders were used here, namely pure aluminum and quasicrystalline particles from the Al-Cu-Fe system. These powers were initially mixed with deionized water, citric acid, and poly(vinyl alcohol). The obtained slurry was frozen while rotating and freeze-dried under vacuum. The green bodies were subsequently heat-treated in a reducing atmosphere. The total porosity and mean pore size evaluated for these scaffolds were 62.4 ± 3.0% and 67.3 ± 2.8 μm, respectively. This is the first time that dynamic freeze-drying has been used in the preparation of QC scaffolds, which reinforces the novelty of this study. In addition, the proposed route is simple, inexpensive, and environmentally friendly, which is also worth highlighting. study iQC i (i-QC freezecasting. freezecasting freeze casting. casting freeze-casting here AlCuFe Al Cu Fe system water acid polyvinyl poly vinyl alcohol. alcohol . alcohol) freezedried dried vacuum heattreated heat treated atmosphere 624 62 4 62. 30 3 0 3.0 673 67 67. 28 2 8 2. μm respectively freezedrying drying addition simple inexpensive friendly highlighting 6 3.

RESUMO Esse artigo toma a caracterização de Lévi-Strauss das “sociedades frias” como inspiração para discutir o regime de historicidade karajá, um povo do Brasil Central. Sua mitologia narra um tempo da criação, onde diversos aspectos do mundo são criados e a humanidade adquire os conhecimentos que hoje a caracterizam enquanto tal. Já a ação no mundo atual não é criadora: antes, as ações fazem aparecer formas que já estavam lá, desde o princípio, pois inscritas pelo mito. Dessa maneira, as ações atuais fazem aparecer ou uma continuidade em relação aos tempos antigos, pois elicitam os mesmos nexos relacionais, ou uma ruptura marcada para com “a cultura”. Em um caso como no outro, o que é colocado em evidência é a potência “fria” de seu regime de historicidade, ou seu caráter contrahistórico. Para dar conta desse regime, escapando da ideia de história formulada em termos de mudança e continuidade, argumento que é preciso separar o problema da história do problema do tempo.

ABSTRACT In this paper, I take Lévi-Strauss’ characterization of “cold societies” as an inspiration from which to discuss the central Brazilian Karajá’s regime of historicity. Their mythology narrates a time of creation when diverse aspects of the world are created and humanity acquires the knowledge that now characterizes it as such. Action in the actual world, on its turn, is not creative: they make appear forms that were already there, for inscribed by the myth. Actual actions therefore make appear either a continuity in relation to “ancient times”, for they elicit the same relational nexus, or a marked rupture in relation to “the culture”. In the one case or the other, what is evinced is the “cold” potency of their regime of historicity, its contra-historical character. To grasp this regime though escaping from the idea of history put in terms of change and continuity, I argue that it is necessary to set the problem of history apart from the problem of time.

Abstract: We aimed to evaluate the penetration of endodontic cement following the removal of calcium hydroxide (Ca(OH)2) dressing using the XP-endo Finisher in association with different irrigating solutions. Sixty premolars were instrumented and applied with a Ca(OH)2 dressing. To remove Ca(OH)2, the teeth were divided into six groups, each with a different volume of sodium hypochlorite (NaOCl) and ethylenediaminetetraacetic acid (EDTA), as well as solution stirring time with XP-endo Finisher (0, 30, and 60 sec). Root canals were filled using the lateral condensation technique. Fluorescein dye was added to the cement for microscopic laser scanning analysis. In the generated images, linear measurements were taken in micrometers, and their averages were calculated. To analyze the perimeter penetration ratio of the cement, the total perimeter of the canal and the segment of the total perimeter of the canal where the endodontic cement penetrated into the dentinal tubules were measured in micrometers. We found that using an XP-endo Finisher in irrigation was more effective than using a needle and syringe during the extension and penetration of endodontic cement. Shaking with XP-endo Finisher with 17% EDTA increased the extent and perimeter of the penetration of the endodontic cement into the dentinal tubules. However, using the XP-endo Finisher with EDTA only was more efficient than using the instrument interchangeably in NaOCl and EDTA. Although XP-endo Finisher contributes to the removal of Ca(OH)2, none of the protocols or instruments used removed all Ca(OH)2 from the root system.

Resumo O presente relato de caso teve como objetivo descrever o manejo da perfuração lateral no terço médio cervical da raiz em dois incisivos superiores com calcificação pulpar utilizando o Bio-C Repair, com estratégias de tratamento clínico seguras e viáveis. Radiografias digitais foram obtidas em diferentes ângulos e analisadas com diferentes filtros. Imagens de tomografia computadorizada de feixe cônico (TCFC) foram solicitadas para mostrar a real posição do canal e a localização da perfuração, e orientar o planejamento estratégico do caso. Posteriormente, o acesso à cavidade foi preparado com auxílio de microscopia cirúrgica. Após a identificação da perfuração, o tecido de granulação foi removido, o canal original foi identificado e, em seguida, recebeu medicação intracanal à base de hidróxido de cálcio. Na segunda visita, a perfuração foi selada com Bio-C Repair e o sistema de canais obturado com cones de guta-percha e cimento endodôntico (Bio-C Sealer). Os dentes foram restaurados com pino de fibra de vidro, 4 mm além do nível da perfuração, e coroas provisórias. Ambos os dentes tratados conforme descrito acima se mostraram funcionais e assintomáticos na avaliação clínica e radiográfica de 1 ano. O Bio-C Repair é sugerido como uma nova opção de cimento endodôntico para o manejo de perfurações laterais, com resultados efetivos observados após um ano de acompanhamento.

Abstract These case reports aimed to describe the management of lateral perforation in the middle cervical third of the root in two maxillary incisors with pulp canal calcification using Bio-C Repair, with safe and viable clinical treatment strategies. Digital radiographic exams were obtained with different angles and analyzed using different filters. Cone-beam computed tomography (CBCT) images were requested to show the actual position of the canal, location of the perforation, and guide the strategic planning of the case. Subsequently, cavity access was prepared with the aid of dental operating microscopy. After perforation was identified, granulation tissue was removed and the original canal was identified and then dressed with calcium hydroxide. In the second visit, the perforation was filled with Bio-C Repair and the canal system filled with gutta-percha points and a root canal sealer (Bio-C Sealer). The teeth were restored with glass fiber post, 4 mm beyond the perforation level, and provisory crowns. Both teeth treated as described above were functional and asymptomatic with a 1-year clinical and radiographic assessment. The Bio-C Repair is suggested as a new cement option for the management of lateral canal perforations, with effective results as observed after a one-year follow-up.

Abstract: This study aimed to describe the morphometric relationship of root canal orifices on the pulp floor in the presence/absence of mesiobuccal second canal (MB2) in the maxillary first molars and other aspects of its internal anatomy. Sixty-two maxillary first molars were scanned by micro-CT. The presence of the MB2 canal was verified. The distance between the center points of the MB1, MB2, distobuccal (DB), and palatal (P) canal orifices on the pulp floor were measured (MB1-MB2, MB1-DB, MB2-DB, MB1-P, and DB-P). The MB1-P to DB-P ratio was calculated. The distances between the anatomic apex and the MB1 and MB2 apical foramina were measured. The length of the band-shaped isthmus was also measured. Student's t-test was applied to verify the association between the presence of an MB2 canal, the interorifice distances, and the ratio of the MB1-P to DB-P distance (α = 5%). The MB2 canal was present in 43 roots (69.35%). Statistics showed significant differences when MB2 was present for the largest MB1-P distance (p < 0.05) and higher values for the MB1-P to DB-P ratio (p < 0.05). A band-shaped isthmus was detected in 25.8% of MB roots. The mean distance from the apical foramen to the isthmus floor ranged from 1.74 for MB1 canals to 1.42 for MB2 canals. Canal orifice distances on the pulp floor may predict the presence of MB2 canals. There was a high incidence of isthmus, accessory canals, and apical delta in the critical apical zone in MB roots of maxillary first molars.

RESUMO O objetivo desta pesquisa foi avaliar e monitorar os caminhões climatizados transportadores de pintos em diversos turnos de viagens, através da tecnologia GPRS (General Packet Radio Service), visando possibilitar um controle térmico em tempo real pelos gestores das indústrias avícolas. O equipamento Control-Broilers foi composto pelo GS-105 e a Plataforma Monitorar®. O GS-105 foi constituído por sensores, microprocessador, GPRS e pilhas. A Plataforma Monitorar® apresentava 9 aplicativos, que atuaram coordenadamente, através da tecnologia web services RESTful. Foram avaliados e monitorados 28 transportes de pintos por meio do Control-Broilers, em um incubatório comercial. Todos os percursos foram supervisionados por dois pesquisadores para assegurar a transmissão dos dados em tempo real, através de computadores portáteis e smartphones. Foram usados três caminhões climatizados, durante dois turnos. Os veículos possuíam as mesmas dimensões, porém, os percursos, tempos de viagens e densidades eram variados. As avaliações temperatura do ar, umidade relativa e entalpia específica dos caminhões fora realizadas em intervalos de um min. O delineamento experimental utilizado foi inteiramente aleatorizado em esquema fatorial 3 x 2, que representaram os três caminhões (CL, CA e JA) e os dois turnos (dia e noite), contendo quatro repetições (viagens). Os caminhões climatizados transportadores de pintos proporcionaram 92,85% de eficiência na transmissão de dados em tempo real, aplicando a tecnologia GPRS. Os caminhões climatizados e os turnos de viagens não apresentaram homogeneidade térmica nas cargas de pintos. O turno da noite foi o que apresentou piores condições térmicas.

ABSTRACT This research aimed to monitor and evaluate air-conditioned trucks transporting day-old chicks, in various shifts of travel, through general packet radio service (GPRS) technology to provide real-time thermal control for poultry industry managers. The Control-Broilers equipment used were GS-105 and the Monitorar Platform. GS-105 is composed of sensors, a microprocessor, GPRS, and batteries. The Monitorar Platform provided nine applications that acted in coordination with web technology RESTful services. Twenty-eight chick transports were evaluated and monitored using the Control-Broilers. Truck routes were supervised by two researchers to ensure real-time data transmission through laptops and smartphones. Three air-conditioned trucks were used during two of days shifts. The vehicles had the same dimensions, but the routes, travel times, and load densities varied. Measurements of the air temperature, relative humidity, and specific enthalpy inside the trucks were recorded every minute. The experimental design was entirely randomized in a 3 × 2 factorial scheme, which represented the three trucks (CL, CA and JA) in two transport shifts (day and night), containing four repetitions (travel).The air-conditioned trucks transporting day-old chicks presented a 92.85% efficiency for real-time data transmission using GPRS technology. The trucks during the travel shifts did not provide thermal homogeneity in chick loads. The night shift presented worse thermal conditions.

RESUMO Esta pesquisa analisou a produção e as características de briquetes compostos de resíduos de Cocos nucifera e da madeira de Eucalyptus pellita. Utilizou-se o delineamento inteiramente casualizado, com sete tratamentos e cinco repetições. Os tratamentos corresponderam às percentagens de resíduos de coco e de eucalipto, como segue: T1: 100% de resíduos de eucalipto; T2: 20% de resíduos de coco + 80% de resíduos de eucalipto; T3: 40% de resíduos de coco + 60% de resíduos de eucalipto; T4: 50% de resíduos de coco + 50% de resíduos de eucalipto; T5: 60% de resíduos de coco + 40% de resíduos de eucalipto; T6: 80% de resíduos de coco + 20% de resíduos de eucalipto e T7: 100% de resíduos de coco. Para a produção dos briquetes utilizou-se como aglutinante a carboximetilcelulose a 0,5% (CMC). As misturas foram compactadas, sob uma carga de 568 kgf cm-², durante três minutos. Após a prensagem, os briquetes foram secos ao ar, até atingirem a umidade de equilíbrio com o ambiente e, em seguida, foram determinadas as características físicas, químicas e energéticas. Os dados foram submetidos à análise de variância, correlações e análise hierárquica de cluster (AHC). Os briquetes produzidos com 100% de resíduos de C. nucifera, apresentaram as maiores umidades de equilíbrio, elevados teores de materiais voláteis e baixos teores de carbono fixo. A densidade básica, a massa específica aparente e o ritmo de queima não foram afetados pela composição e pela umidade de equilíbrio dos briquetes.

ABSTRACT This research analyzed the production and characteristics of briquettes composed of residues of Cocos nucifera and Eucalyptus pellita wood. A completely randomized design was used, having seven treatments and five repetitions per treatment. The treatments corresponded to waste percentages of coconut and eucalyptus residues as following: T1: 100% eucalyptus waste; T2: 20% coconut waste + 80% of eucalyptus waste; T3: 40% coconut waste + 60% of eucalyptus waste; T4: 50% coconut waste + 50% of eucalyptus waste; T5: 60% coconut waste + 40% of eucalyptus waste; T6: 80% coconut waste + 20% of eucalyptus waste; and, T7: 100% coconut waste. For the production of briquettes, 0.5% carboxymethylcellulose (CMC) was used as the binder. The mixtures were compacted under a load of 568 kgf cm-² for three minutes. After pressing, the briquettes were air-dried to the equilibrium moisture of the environment and, then, analyzed for physical, chemical and energy characteristics. The data were analyzed through analysis of variance, correlations and hierarchical cluster analysis (HCA). The briquettes produced with 100% of C. nucifera residues had the highest equilibrium moisture content, high volatile matter concentrations, and low fixed carbon concentrations. The basic density, the apparent specific mass and the burning rate were not affected by the composition and by the equilibrium moisture of the briquettes.

RESUMO Objetivo: O objetivo deste estudo foi avaliar a incidência do tratamento endodôntico e a qualidade das obturações de canais radiculares numa população de estudantes de odontologia brasileiros.

Métodos: Um total de 407 estudantes de odontologia foi avaliado por meio de questionários para identificação de tratamentos endodônticos, sendo cada tratamento radiografado para a análise da presença de radioluscência periapical e a qualidade da obturação endodôntica. Resultados: Foram encontrados 40 canais radiculares obturados, sendo 32 (80%) com adequada obturação, sete (17,5%) com subobturação e um (2,5%) sobreobturado. Conclusão: Este estudo mostrou uma baixa prevalência de tratamento endodôntico em estudantes de odontologia, e os tratamentos avaliados apresentaram alta qualidade, com poucos casos sugerindo lesões periapicais.

ABSTRACT Objective: The purpose of this study was to evaluate the incidence of endodontic treatment and the quality of root canal fillings in Brazilian undergraduate dental students. The study was similar those conducted 10, 20, 30, and 40 years earlier. Methods: A total of 407 undergraduate dental students were evaluated by using questionnaires to identify endodontic treatments, with each treatment being radiographed for the analysis of the presence of a periapical radiolucency and the quality of the root canal filling. Results: Forty root canal fillings were found: 32 (80%) completely filled, seven (17.5%) incompletely filled, and one (2.5%) overfilled. Conclusion: This study showed a low prevalence of endodontic treatment in dentistry students, and the evaluated root canals that were filled were high quality, with few cases suggesting periapical lesions.

RESUMO A rentabilidade financeira é um fator tão importante quanto quantificar a produção utilizando novas tecnologias. Assim, objetivou-se analisar em curto e longo prazo a rentabilidade financeira da produção orgânica de minitomates em casas de vegetação com diferentes graus tecnológicos de controle parcial dos elementos micrometeorológicos. O experimento foi desenvolvido no campo experimental da FEAGRI/UNICAMP (SP) em três casas de vegetação com sistemas automatizados de ventilação mecânica, resfriamento evaporativo e tela termorrefletora, sendo estas cultivadas com a cultivar Carolina em espaçamento 0,5x0,9 m em duas hastes, e manejo da produção e adubação orgânica. As médias dos dados de produção dos tratamentos {três casas de vegetação (A= climatizada, B= tela móvel e C= tela fixa), duas formas de cultivo (vasos e canteiros) e cinco doses de biofertilizante (0, 50, 100, 150, e 200%)} foram avaliadas em análise conjunta. Assim, avaliou-se através das receitas e custos de produção os indicadores econômicos {relação benefício custo (B/C), valor presente líquido (VPL), Taxa interna de retorno (TIR) e Payback (PV)}. De acordo com os resultados, a melhor alternativa de rentabilidade líquida mensal ciclo (500 m2) foi de aproximadamente 1 e 1,5 salários mínimo para a condição com e sem mão de obra particular, respectivamente, associado à casa de vegetação de médio grau tecnológico, utilizando a forma de cultivo em canteiros. A viabilidade econômica do projeto em longo prazo a taxas de juros acima de 3% (a.a) mostrou-se consistente, porém o período de payback mesmo à taxa de juros 1% a.a foi elevada (6,54 anos) em condições de financiamento.

ABSTRACT Financial profitability is a factor as important as quantifying production using new technologies. This study was installed to evaluate short and long term financial viability of organic production of cherry tomatoes. Plants were grown in a greenhouse under diverse technological degrees for partial control of micrometeorological elements. The experiment was carried out at the experimental field FEAGRI/UNICAMP in three greenhouses with automated mechanical ventilation systems, evaporative cooling and thermo reflective screen. We cultivated Carolina cultivar in a spacing of 0.5x0.9 m, each plant conducted with two stems, under organic production and fertilization management. The average of production data of treatments {three greenhouses (A= climate-controlled, B= mobile screen and C= fixed screen), two cultivation systems (pots and soil beds) and five biofertilizer doses (0, 50, 100, 150, and 200%)} were evaluated using joint analysis. Thus, the economic indicators {cost benefit ratio (B/C), net present value (NPV), internal rate of return (IRR) and Payback (PV)} were evaluated through revenues and production costs. The best alternative to net monthly cycle profitability (500 m2) was approximately 1 and 1.5 minimum wage with and without particular labor, respectively, associated with the greenhouse of medium technological level, using soil bed cultivation system. The economic viability of the project in long-term interest rates above 3% (a.a) was consistent, but the payback period even with a rate of 1% a.a was high (6.54 years) in financing conditions.

Resumo O artigo apresenta a Separação de Poderes como um princípio. Isso significa que é uma das várias opções políticas possíveis. Tomamos essa concepção e então objetivamos explicar como ela se desenvolve com relevância em um Estado de Direito e seus procedimentos. Foi percebido analiticamente que essa concepção é idealizada pois falha em abordar problemas práticos. A principal problemática confrontada é em relação à atividade do Judiciário, exemplificada por conflitos brasileiros entre os diferentes poderes, neste trabalho se aborda, para tanto, o caso da vaquejada. Para tentar superar esses problemas, a hipótese apresentada é que uma teoria dialógica pode fornecer algumas respostas promovendo o diálogo através do equilíbrio e da parceria entre os poderes e os cidadãos.

Abstract The paper presents the Separation of Powers as a principle. It means that it is one of several possible political choices. We take this conception and then we aim to explain how it develops with relevance in a Rule of Law and its procedures. It was analytically perceived that such conception is idealized because it fails to address practical problems. The main problematic confronted is in relation to the activity of the Judiciary, exemplified through Brazilian conflicts between the different powers, in this paper we approach, for this purpose, the vaquejada case. In order to try to overcome such problems, the presented hypothesis is that a dialogic theory can provide some answers by promoting dialogue through equilibrium and partnership between the powers and citizens.

O presente trabalho teve como objetivo estudar via modelos mistos, o desempenho de genótipos de mandioca no estado de Santa Catarina. Os delineamentos experimentais foram conduzidos durante duas safras consecutivas (2010/11 e 2011/12), em seis municípios produtores de mandioca de três regiões do estado. Foram avaliados 12 genótipos de mandioca de indústria no experimento em blocos casualizados com três repetições. As parcelas eram compostas de 30 plantas dispostas em seis linhas de cinco plantas com área útil equivalente às doze plantas centrais. Foi avaliada a produtividade de raízes em cada local e na média de todos os locais, a estabilidade (MHVG), a adaptabilidade (PRVG) e a estabilidade e a adaptabilidade simultaneamente (MHPRVG). Os clones de mandioca 269, 849 e 422 destacaram-se entre os genótipos avaliados, sendo considerados promissores para o cultivo em Santa Catarina. A metodologia de modelos mistos é uma boa opção para avaliação do desempenho de genótipos de mandioca em fases avançadas de seleção.

The present work aimed to study via mixed models, the performance of cassava genotypes in the state of Santa Catarina. The experiments were conducted for two consecutive seasons (2010/11 and 2011 /12) in six locations in cassava producers of three regions of the state. Twelve cassava genotypes for industry were evaluated in a randomized block design with three replications. The plots were composed of 30 plants arranged in six rows of five plants with useful area equivalent to the twelve central plants. Productivity of roots at each experiment and the average of all places, stability (MHVG), adaptability (PRVG) and both stability and adaptability (MHPRVG) were evaluated. The cassava clones 269, 849 and 422 stood out among the genotype, being considered promising for cultivation in Santa Catarina. The mixed model methodology is a good tool for evaluating the performance of cassava genotypes in advanced stages of selection.
