Os tijolos de solo-cimento constituem uma das alternativas para a constru??o em alvenaria. Esses elementos, ap?s pequeno per?odo de cura, garantem resist?ncia ? compress?o simples similar ? dos tijolos maci?os e blocos cer?micos, sendo a resist?ncia tanto mais elevada quanto maior for ? quantidade de cimento empregada. Foi utilizado cimento CPIIZ-32, res?duo de cascalho de perfura??o de po?os de petr?leo proveniente da perfura??o de po?os Onshore, no munic?pio de Mossor?/RN, fornecido pela Petrobras e cinzas do baga?o de cana-de-a??car. Para a determina??o da mistura ?tima, estudou-se a inclus?o de teores de CBC (2%; 4%; 6%; e 8%) onde foram confeccionados 18 corpos-de-prova. A avalia??o dos tijolos confeccionados foi feita a partir de ensaios de compress?o simples, perda de massa por imers?o e absor??o de ?gua. Os resultados experimentais comprovaram a efici?ncia e o elevado potencial de utiliza??o do res?duo proveniente da perfura??o de po?os de petr?leo e cinza do baga?o de cana-de-a??car, tornando o tijolo res?duo-cimento com uma maior resist?ncia mec?nica e menor absor??o de ?gua. / In recent years the construction industry is a major world representation in the consumption of natural resources and generation of wastes which lead to a greater environmental impact. Thus, it is of fundamental importance to planning the consumption of non-renewable natural resources, in addition to waste management, reuse and incorporate them in the process of manufacturing new materials. The present work is the study of the characteristics and technological properties of solid waste-cement bricks and cast formulated from binary and ternary mixtures cement Portland, gravel from the oil well drilling, with and without addition of cane sugar ashes residue that can be used by industry, with the goal of improving performance, reducing cost and increasing its useful life. Was used CPIIZ-32 cement, drill cuttings residue of oil wells from drilling onshore wells in the municipality of Mossor? / RN, supplied by Petrobras and ashes of sugarcane bagasse. To determine the optimum mix was used to study the inclusion of gray levels (2%, 4%, 6% and 8%) where bodies were prepared 18-specimens for each formulation. The evaluation was made of bricks made from simple compression tests, weight loss by immersion and water absorption. The experimental results have proved the efficiency and the high potential for use of drill cuttings and ash cane bagasse, making the brick-cement residue with a higher strength and lower water absorption. The best result in terms of mechanical strength and water absorption, both for the binary and ternary blend formulation was 86% gravel, 12% cement and 2% ash.

Entretecendo os apontamentos e o teatro de Canetti com os conceitos filos?ficos da ?est?tica negativa? de Adorno, percebe-se um espa?o para a reflex?o de teorias que se sucederam, como as rela??es de poder de Foucault, presentes em Microf?sica do poder e os discursos de resist?ncia e poder desenvolvidos por Deleuze e Guatarri em Mil Plat?s e O Anti-?dipo. Apesar de suas obras terem sido escritas entre 1932 e 1956, todas apresentam uma cr?tica exasperada ao modernismo e caracter?sticas que n?o auxiliaram o seu reconhecimento pela cr?tica da ?poca, o que fez com que a dramaturgia de Canetti fosse redescoberta ap?s o autor receber o Pr?mio Nobel em 1981. / The purpose of this dissertation is to analyse the dramaturgic work of the Bulgarian author Elias Canetti, composed by the plays The Wedding, Comedy of Vanity and Their Days are Numbered, seeking to comprehend how the contemporary critic theories act on his trilogy, making a dialogue with theoretical references which may justify its approaching to the postmodernism. In this perspective, the theories by Jean-Fran?ois Lyotard, Fredric Jameson and J?rgen Habermas contribute for a better comprehension of the postmodernity phenomenon. Undertaking Canetti?s notes and theatre with the philosophical concepts of Adorno?s negative aesthetics, we realise there is a space to reflect upon the theories which befell, like Foucault?s power relations in Micro-physics of Power and the discourses of resistance and deterritorialisation developed by Deleuze and Guattari in A Thousand Plateau and Anti-Oedipus. Even though Canetti?s plays were written between 1932 and 1956, all of them show a strong critic against modernism, and their characteristics did not help their recognition by the critics, which resulted in a rediscovery of Canetti?s plays after the author won the Nobel Prize in 1981.

Moisture and Temperature are the two most important factors that lead a cotton Spinning sector and influence its quality. Those two properties can change the entire Spinning process. Understanding this, moisture and temperature must be kept under control when used during the Spinning process, once the environment is hot and dry, the cotton yarns absorb moisture and lose the minimal consistency. According to this information, this paper was developed testing four types of cotton yarns, one kind of cotton from Brazil and the others from Egypt. The yarns were exposed to different temperatures and moisture in five different tests and in each test, six samples that were examined through physical and mechanical tests: resistance, strength, tenacity, yarn?s hairness, yarn?s evenness and yarn?s twisting. All the analysis were accomplished at Laborat?rio de Mec?nica dos Flu?dos and at COATS Corrente S.A., where, it was possible to use the equipments whose were fundamental to develop this paper, such as the STATIMAT ME that measures strength, tenacity, Zweigler G566, that measure hairiness in the yarn, a skein machine and a twisting machine. The analysis revealed alterations in the yarn?s characteristics in a direct way, for example, as moisture and temperature were increased, the yarn?s strength, tenacity and hairness were increased as well. Having the results of all analysis, it is possible to say that a relatively low temperature and a high humidity, cotton yarns have the best performance / O algod?o ? uma fibra t?xtil hidr?fila e por essa raz?o muda suas caracter?sticas em fun??o das condi??es do ambiente. A umidade e a temperatura s?o dois fatores que influenciam o ambiente de uma fia??o de algod?o. Estes dois fatores podem alterar a qualidade de toda uma produ??o de fios. Sendo assim, umidade e temperatura devem ser mantidas sob o controle para o processamento do algod?o, uma vez que em um ambiente seco e quente os fios de algod?o liberam umidade e se rompem, aumentando o ?ndice de quebra da fia??o com o ambiente frio e ?mido, os fios absorvem umidade e perdem a consist?ncia m?nima.Com base nessas informa??es, este trabalho foi desenvolvido experimentando quatro tipos de fio de algod?o sendo de origem brasileira e os demais, de origem eg?pcia. Os fios foram expostos a temperatura e umidade diferentes em cinco experimentos distintos, contendo cada experimento seis amostras que passaram por testes f?sicos e mec?nicos: resist?ncia, for?a, tenacidade, pilosidade, t?tulo e tor??o. As an?lises foram realizadas no Laborat?rio de Mec?nica dos Fluidos na Universidade Federal do Rio Grande do Norte e na empresa COATS Corrente S.A., onde foi poss?vel fazer uso dos equipamentos fundamentais para o desenvolvimento deste trabalho, tais como o STATIMAT ME que mede a resist?ncia, for?a e tenacidade do fio, Zweigler G566 o qual mensurou a quantidade de pilosidade no fio e, a meadeira e o torc?metro, respons?veis pelo t?tulo e tor??o. As an?lises revelaram altera??es nas caracter?sticas dos fios de forma diretamente proporcional, como por exemplo, conforme aumentava-se a umidade e temperatura havia um aumento da resist?ncia, for?a, tenacidade e pilosidade. Em posse desses resultados, ? poss?vel afirmar que a uma temperatura relativamente baixa e uma umidade alta, os fios de algod?o tem sua performance m?xima

The corpus of the research is constituted by the news of the period informed in the printed newspapers: Correio do povo and O Nordeste, both from Mossor?/RN, and the narratives presented in the cord?is de acontecido : Mossor? in the resistance to the group of Lampi?o; Lampi?o in Mossor? in 1927, and Mossor? attacking to the group of Lampi?o, all potiguar poets. The analysis of the texts had as theoretical background the studies of: The texts analysis had as theoretical background The Discourse Analysis; The Argumentation Theory and the studies about Discourse Genres. We focused our discussion in the emphasis given to the news in the discursive perspective of the social-historic memory constructed in the cord?is, from ideological values (political, economical, religious etc.) that pass to be a fundamental element in the constitution of the image of the resistance. Methodologically, this is a documental research, since it makes use essentially of the written document. Regarding to the nature of the data, the research is characterized as a qualitative one. In the analysis, we considered the argumentative techniques adopted in the defense of the thesis, the meaning effects suggested, and the genres mentioned, that revealed to us the manner in which the episode was informed by the newspapers and the cord?is. That way, we affirm, based on the positions assumed by the announcers of the genres analyzed who defended clearly positions in favor of the defense of Mossor?, that the relation between both is captured interdiscursively, since they are asked by the same ideology, and converge to the same discursive formation, defending identical positions, and structuring their discussions with resembling argumentative techniques, reason by which take us to believe that the discourse presented in that social activity demonstrates and develops traces of a manipulation of the subject. In this case, the discursive construction of the text points towards determining standard of repetition, since the linguistic context is characterized in the journalistic field, and in the poetic field assuming, in the first instance, a local expression / Esta disserta??o tem como objetivo investigar as rela??es interdiscursivas no processo de constru??o da linguagem em uso nas esferas po?tica e jornal?stica, a fim de perceber como o g?nero not?cia ? constitu?do em diferentes campos de atividade social, bem como, analisar os processos argumentativos que estruturam os discursos escritos sobre o epis?dio da resist?ncia ao bando de Lampi?o em Mossor? no ano de 1927. O corpus da pesquisa ? constitu?do pelo notici?rio da ?poca veiculado nos jornais impressos Correio do povo e O Nordeste, ambos de Mossor?/RN, assim como, as narrativas presentes nos cord?is de acontecido: Mossor? na resist?ncia ao bando de Lampi?o; Lampi?o em Mossor? em 1927 e O ataque de Mossor? ao bando de Lampi?o, todos de poetas potiguares. A investiga??o dos textos teve como suporte te?rico A An?lise do Discurso; A Teoria da Argumenta??o e os estudos sobre G?neros do Discurso. Tem como foco o (re)enquadre dado ? not?cia na perspectiva discursiva da mem?ria s?cio-hist?rica constru?da nos cord?is a partir de valores ideol?gicos (pol?tico, econ?mico, religioso) que passam a ser elemento fundamental na constitui??o da imagem da resist?ncia. Metodologicamente, esta ? uma pesquisa de cunho documental, uma vez que faz uso essencialmente do documento escrito.

The genetic variability of 28 isolates of R. areola was studied using RAPD markers. The pathogenicity evaluation was realized by the inoculation of 6 isolates on cotton varieties Guazuncho-2 (Gossypium hirsutum) and VH8-4602 (Gossypium barbadense). The inheritance of disease resistance was studied using an artificially inoculated population of F2 individuals derived from the intercross of Guazuncho-2 (susceptible variety) end VH8-4602 (resistant variety), and also the parents and F1 individuals. Molecular polymorphism between the G. hisutum varieties DeltaOpal (suscetible) and CNPA CO-11612 (resistant) was estimated by 118 SSR and 24 AFLP markers. The parental genotypes Guazuncho-2 and VH8-4602 were selected for mapping, and then Recombinant Inbred Lines (RIL?s) derived from this crossing were evaluated with SSR 12 markers. The analysis of population structure of R. areola revealed that the three subpopulations were genetically simillar (Gst=0.18), and the isolates from Goi?s and Minas Gerais were more similar to each other (0,92). This probability can be related to the relatively high gene flow among the three subpopulations (Nm=2.20). The isolates R. areola 9.1, from Minas Gerais State and 8.1 and 8.3 from Goi?s State were the most aggressive ones to the susceptible variety Guazuncho-2. The variety VH8-4602 presented high level of resistance to ramularia spot. No differential interaction was observed between the pathogens and the analyzed varieties, and the resistance was classified as horizontal. The quantification of disease by number of necrotic lesions and number of spores in individual plants of F1 and F2 generations from the crossing between the varieties Guazuncho-2 and VH8-4602 presented continuous distribution, suggesting polygenic resistance. The resistance is probabilly recessive, since necrotic lesions and sporulation were observed on F1 plants. The molecular polymorphism between DeltaOpal e CNPA CO-11612 lineages was low (6%), then would be difficult to accomplish molecular mapping of disease resistance using this intercross. With the genotyping of the RIL s it was verified that 25% of the markers segregated in the proportions proposed by Mendel s Law and 75% of the studied markers presented segregation distortion in favor to the parental G. hirsutum. Both the low genetic variability of the pathogen and the number of resistance genes suggest that durable genetic resitance may be achieved / Este estudo teve como objetivos estudar a estrutura gen?tica e patog?nica de isolados de Ramularia areola do Brasil e caracterizar a resposta de resist?ncia no algodoeiro ? mancha-de-ramul?ria. Foi avaliada a variabilidade gen?tica de 28 isolados do pat?geno, utilizando-se marcadores RAPD. A avalia??o da patogenicidade de 6 desses isolados foi realizada ap?s a inocula??o nas variedades Guazuncho-2 (Gossypium hirsutum) suscet?vel e VH8-4602 (Gossypium barbadense) resistente ? doen?a. A heran?a da resist?ncia no algodoeiro ? doen?a foi caracterizada pela medi??o de intensidade da doen?a nas variedades Guazuncho-2 (G. hirsutum), suscet?vel, e VH8-4602 (G. barbadense), resistente ? doen?a, e nas gera??es F1 e F2 provenientes do cruzamento entre elas. O polimorfismo molecular entre as linhagens de G. hirsutum DeltaOpal e CNPA CO11612, contrastantes fenotipicamente quanto ? resist?ncia ? doen?a foi avaliado utilizando-se 118 marcadores SSR e 24 AFLP. Para mapeamento molecular dos genes de resist?ncia, linhagens recombinantes RIL s derivadas do cruzamento entre Guazuncho-2 e VH8-4602 foram genotipadas utilizando marcadores SSR. A an?lise da estrutura da popula??o de R. areola revelou que as tr?s subpopula??es foram semelhantes geneticamente (Gst=0.18). Os isolados de Goi?s e Minas Gerais obtiveram maior similaridade gen?tica (0,92), que pode estar associada com o alto fluxo gen?tico existente entre as subpopula??es que foi de (Nm=2.20). Quanto ? patogenicidade, os isolados de R. areola 9.1, coletado no estado de Minas Gerais, 8.2 e 8.3 de Goi?s, foram mais agressivos na variedade suscet?vel Guazuncho-2. A variedade VH8-4602 apresentou alto n?vel de resist?ncia ? doen?a. N?o foi observada intera??o diferencial entre os pat?genos e as variedades analisadas, sendo a resist?ncia classificada como horizontal. Na an?lise dos indiv?duos das gera??es F1 e F2, provenientes do cruzamento entre Guazuncho-2 e VH8-4602, a quantifica??o de sintomas da doen?a atrav?s da contagem de manchas necr?ticas e pelo n?mero de esporos mostrou varia??o cont?nua da resist?ncia ? doen?a nos indiv?duos da gera??o F2, indicando que a heran?a ? polig?nica. O aparecimento de sintomas e esporula??o nos indiv?duos F1 mostrou que a resist?ncia ? recessiva. O polimorfismo molecular entre as linhagens de G. hirsutum, DeltaOpal e CNPA CO11612 foi de 6%, portanto baixo, para realizar o mapeamento. Durante genotipagem das RIL?s foi verificado que 25% dos marcadores segregaram de acordo com as propor??es das leis de Mendel, e 75% desses marcadores apresentaram distor??o de segrega??o, com aumento da propor??o de genes do parental G. hirsutum. A baixa variabilidade do pat?geno e n?mero de genes de resist?ncia sugere que a resist?ncia gen?tica ao pat?geno tenha alta durabilidade

Entretanto, n?o h? dados sobre esse fen?meno para o semi?rido brasileiro. Sendo assim, este estudo teve como objetivo o isolamento e a identifica??o das bact?rias de import?ncia m?dica contaminantes de ambientes qu?ticos no semi?rido potiguar, a caracteriza??o da resist?ncia antimicrobiana, e a formula??o de propostas para educa??o em sa?de e a??es para vigil?ncia ambiental em sa?de. Com este prop?sito foram coletadas amostras de ?gua de quatro reservat?rios do semi?rido potiguar durante os per?odos seco e chuvoso. As amostras foram processadas e os microrganismos foram isolados e identificados seguindo orienta??es de bibliografias especializadas. Em seguida foram realizados os testes de sensibilidade antimicrobiana em disco difus?o, calculado o ?ndice de m?ltipla resist?ncia antibi?tica (MAR) e classificados os organismos com multipla resist?ncia ?s drogas (MDR). Tamb?m foram propostas a??es para preven??o e educa??o em sa?de, bem como para vigil?ncia ambiental em sa?de. Adicionalmente, foi avaliada, na Universidade de Minnesota, nos Estados Unidos, a influ?ncia da concentra??o do f?sforo em meio l?quido (caldo nutriente, C:P 100:1, 1000:1 e 100.000:1) sobre a expres?o fenot?pica da resist?ncia ? tetraciclina, ao cloranfenicol e a eritromicina, de 41 cepas bacterianas dos Estados Unidos utilizando a t?cnica da Concentra??o Inibit?ria M?nima (CIM) e da Concentra??o Bactericida M?nima (CBM). Ao todo foram isoladas 168 bact?rias, 56% no per?odo chuvoso, com 97,6% pertecentes ao grupo das Gram-negativas, com a Fam?lia Enterobacteriaceae apresentando a maior preval?ncia entre esse grupo (73,2%). 95,3% das bact?rias resistentes aos antimicrobianos foram isoladas durante o per?odo seco e o ?ndice MAR foi maior no reservat?rio Passagem das Tra?ras, com 56% de chance para que as bact?rias encontradas na ?gua desse reservat?rio procedam de uma fonte de contamina??o com maior risco para a sa?de humana. N?o houve diferen?a estat?stica da ocorr?ncia de g?neros e esp?cies bacterianos entre os per?odos seco e chuvoso e nem entre os reservat?rios, com p=0,255. Tamb?m n?o houve diferen?a estat?stica do ?ndice MAR entre os per?odos e os reservat?rios, com p=0,224. Quando avaliada a CIM, o meio com C:P de 100.000:1, considerado com a menor concentra??o de f?sforo, parece aumentar a sensibilidade das bact?rias ao cloranfenicol e a eritromicina quando comparado aos resultados do caldo nutriente para os mesmos antimicrobianos, com um p=0,023. Nas escolas que atendem as comunidades ribeirinhas usu?rias da ?gua dos reservat?rios, s?o propostas a??es de educa??o em sa?de que visem o levantamento de concep??es sobre o conhecimento do uso dos antimicrobianos e do surgimento da resist?ncia bacteriana a essas drogas, bem como o desenvolvimento de material para educa??o em sa?de. E no n?cleo de Vigil?ncia Ambiental em Sa?de da SESAP, s?o propostas a inclus?o das bact?rias resistentes aos antimicrobianos isoladas de ambientes aqu?ticos como indicadores de risco para a sa?de p?blica, a formula??o de pol?ticas p?blicas visando o controle das atividades que contaminam esses recursos com esses organismos e tamb?m o monitoramento peri?dico da ?gua dos diversos ambientes aqu?ticos. / Bacterial resistance to antimicrobials became a serious public health problem around the world, and different aquatic environments are contaminated with these organisms. However, there is no data about this phenomenon in the Brazilian semiarid region. Therefore, this study had as main the isolation and identification of contaminant harmful bacteria of potiguar semiarid aquatic environments, characterization of antimicrobial resistance, development of proposals in health education and actions for environmental health surveillance. With this purpose were collected water samples from four potiguar semiarid reservoirs during dry and rainy season. Those samples were analyzed and microorganisms were isolated and identified following specialized literature orientation. Then antimicrobials susceptibility disk diffusion test were performed, Multiple Antibiotic Resistance (MAR) index was calculated, and Multiple Drug Resistance (MDR) classification was used. Also were proposed actions for health prevention and education. In addiction, was evaluated, in Minnesota University/United States of America, the influence of phosphorus concentration in broth medium (Nutrient broth, 100:1, 1000:1 and 100.000:1 C:P ratio) over phenotypic resistance expression to tetracycline, chloramphenicol and erythromycin in 41 American aquatic bacterial strains by using Minimal Inhibitory Concentration (MIC) and Minimal Bactericidal Concentration (MBC) techniques. Altogether were isolated 168 bacteria from the Brazilian semiarid reservoirs, 56% in rainy season, with 97,6% from Gram-negative group, and 73,2% from Enterobacteriaceae Family. Ninety five point three percent of antimicrobial resistant bacteria were isolated during dry season and MAR index was higher for Passagem das Tra?ras reservoir, with 56% of chance that bacteria found in that reservoir has proceeded from high risk source of contamination for human health. There were no statistical differences of bacterial genera and species occurrence between dry and rainy season nor between reservoirs, with p=0,255. Also, there were no statistical differences in MAR index between seasons nor between reservoirs, with p=0,244. When MIC was evaluated, the 100.000:1 C:P ratio medium, considered the one with lower concentration of phosphorus, seemed to increase bacterial susceptibility to chloramphenicol and erythromycin when comparing to nutrient broth results for the same antimicrobials, with p=0,023. At schools that serve riverine communities water reservoirs user were proposed activities for health education aiming describe conceptions about antimicrobial use knowledge and the emergency of bacterial resistance to those drugs, as well as the development of materials for health education. At SESAP Environmental Health Surveillance group were proposed inclusion of antimicrobial resistant bacteria isolated in aquatic environments as indicator of risk for public health, as well as formulation of public policies to control activities that contaminate these sources with those organisms, and also the water periodic monitoring of several aquatic environments.

Em primeira an?lise, foi variado o teor do agregado gra?do no tra?o de refer?ncia, onde o percentual de agregado gra?do em fun??o da quantidade total dos agregados foi de 59% a 69%. Para a segunda an?lise foi reproduzido o tra?o de refer?ncia apenas com agregados de di?metros m?ximos 12,5 mm, 19 mm e 25 mm. Para ambas as an?lises foram feitos ensaio de resist?ncia ? compress?o axial, tra??o na flex?o e na compress?o diametral, m?dulo de elasticidade, tenacidade ? fratura e energia de fratura. Os resultados da an?lise da influ?ncia do teor mostraram que o tra?o com menor teor de agregado gra?do - T (59%) apresentou maiores resist?ncias mec?nicas em rela??o ao tra?o de refer?ncia - REF (64%), com aumentos de 8% para a resist?ncia ? compress?o e tra??o na flex?o, enquanto sua tenacidade ? fratura e energia de fratura diminu?ram em 7% e 12%, respetivamente. J? o tra?o com maior teor de agregado - T (69%), apresentou diminui??o na resist?ncia mec?nica em 12% para resist?ncia ? compress?o e tra??o na flex?o, por?m aumento de tenacidade ? fratura e energia de fratura de 4% e 2%, respectivamente. J? os resultados da an?lise da influ?ncia do di?metro m?ximo do agregado gra?do, mostraram que a diminui??o do di?metro m?ximo do agregado causou aumento da resist?ncia mec?nica e diminui??o dos par?metros de fratura. O tra?o VAR. 12, apresentou aumentos em rela??o ao tra?o de refer?ncia (REF) de 12% para a resist?ncia ? compress?o axial e 19% para a resist?ncia ? tra??o na flex?o, por?m com redu??es de 38% para a tenacidade a fratura e 22% para a energia de fratura. Os maiores resultados dos par?metros de fratura nesta an?lise foram apresentados pelo tra?o de refer?ncia ? REF, por?m com diferen?a considerada insignificante em rela??o ao tra?o VAR. 25. / This study aims to analyze the influence of the large aggregate on the mechanical strength and fracture properties of a concrete headed for rigid paving, used in the constructions of duplication and capacity adaptation of the BR-101 / RN, Northeast corridor, between cities from Parnamirim / RN and Ar?s /RN. In the first analysis, the content of the aggregate was varied in the reference tract, in which the percentage of large aggregate as a function of the total amount of the aggregates was from 59% to 69%. For the second analysis, the reference trace was reproduced only with aggregates with maximum diameters, such as 12.5 mm, 19 mm and 25 mm. For both analyzes, axial compression, flexural tensile and diametral compression, modulus of elasticity, fracture toughness and fracture energy were tested. The results of the analysis of the contente influence showed that the trait with lower content of large aggregate ? T (59%) presented higher mechanical resistance in relation to the reference trait ? REF (64%), with increases of 8% for resistance to compression and tensile strength in flexion, while its fracture toughness and fracture energy decreased by 7% and 12%, respectively. On the other hand, the trait with higher T - aggregate content (69%) showed a decrease in mechanical strength of 12% for compression strength and flexural tensile strength, but an increase of fracture toughness and fracture energy of 4% and 2%, respectively. With regard to the results of the influence analysis of the maximum diameter of the large aggregate showed that the reduction of the maximum diameter of the aggregate caused an increase in the mechanical resistance and decrease of the fracture parameters. The VAR - 12 trait presented increases with respect to the reference trajectory (REF) by 12% for the axial compressive strength and 19% for tensile strength in the flexure, but with reductions of 38% for fracture toughness and 22% for energy of fracture. The greatest results of the fracture parameters in this analysis were presented by the REF- reference trait , but with a difference considered insignificant in relation to the VAR- 25 trait.

Para a an?lise da susceptibilidade a ocorr?ncia de movimentos de massas foi utilizada a metodologia de processo de an?lise hier?rquica ou AHP (Analytic Hierarchy Process) em combina??o com o uso dos sistemas de informa??o geogr?fica SIG. A determina??o dos par?metros de resist?ncia dos solos, foi realizado atrav?s de ensaios de compress?o triaxial tipo CU em condi??es saturadas, e ensaios de compress?o triaxial tipo CW para a condi??o de umidade residual. Para a determina??o das curvas de reten??o dos solos foi usado o m?todo do papel filtro, e as equa??es de Chandler et al. (1992) e posteriormente foi realizado o ajuste das curvas de reten??o pelo m?todo de Van Genuchten (1980). A partir dos resultados de ensaios triaxiais, foi ent?o, realizada a previs?o da resist?ncia ao cisalhamento dos solos n?o saturados a partir do modelo hiperb?lico proposto por Vilar (2007). A partir das se??es suscept?veis ? ocorr?ncia dos movimentos de massa e dos par?metros de resist?ncia dos solos estudados, foram realizadas an?lises da estabilidade das encostas a fim de quantificar o fator de seguran?a das mesmas. O m?todo utilizado nas an?lises de estabilidade foi o SRM, implementado no Software OPTUM, considerando diferentes condi??es de satura??o, a saber: solos sob condi??o natural de campo, solo com 50% do grau de satura??o e, por fim, considerando o solo completamente saturado. Nas an?lises foram consideradas tamb?m a presen?a de camadas de solo cimentado e fendas de tra??o presentes no topo da fal?sia. Ao todo a encosta foi subdividida em tr?s solos predominantes, os quais est?o posicionados na base, na se??o intermedi?ria e no topo da fal?sia, denominados solo-1, solo-2 e solo-3, respectivamente. Estes solos foram caracterizados como areia argilosa (SC), areia Silto-Argilosa (SM), areia mal graduada (SP). Quanto as curvas de reten??o, os tr?s solos apresentam comportamento bimodal, t?picas de solos com granulometrias de material com macroporos e microporos. Finalmente os resultados obtidos destas an?lises num?ricas, foram relacionados inicialmente com o modelo de susceptibilidade produzido a partir da metodologia AHP-SIG, concluindo que este modelo encontra-se em boa concord?ncia, evidenciado pelos resultados das an?lises num?ricas e pelos vest?gios de movimentos vistos em campo. Os resultados das an?lises tamb?m foram relacionados com os tipos de movimentos de massa, concluindo que tanto os fatores geomorfol?gicos, quanto os graus de satura??o resultam em diferentes tipos de movimentos para se??es caracter?sticas pr?prias destas geomorfologias (fal?sias), verificando desta forma os movimentos sugeridos nos estudos de Santos Jr et al.(2004) e Souza J?nior (2013), onde foram relacionados tr?s tipos de perfis com diferentes morfologias e seus poss?veis movimentos de massa, tombamentos, quedas de blocos e escorregamentos. / The aim of this research is to evaluate the susceptibility conditions to the occurrence of mass movements and slope stability of the Center of Launches from Barreira do Inferno (CLBI) using the method of Strength Reduction Method ou SRM, on unsaturated conditions in the Northeast of Brazil. The analysis of the susceptibility to the occurrence of mass movements, the methodology called the Analytic Hierarchy Process was used along with the GIS geographic information systems. In order to determine the resistance parameters of the soils, triaxial compression tests were carried out under saturated conditions CU and triaxial compression tests CW were performed for the residual moisture condition. The determination of soil retention curves, the filter paper method was considered, equations by Chandler et al. (1992), and the adjustment of the retention curves developed by Van Genuchten (1980). From the results of the triaxial tests, the prediction of the shear strength of the unsaturated soils was performed using the hyperbolic model proposed by Vilar (2007). Then, from the susceptible sections to the occurrence of mass movements and the resistance parameters of the studied soils, analyzes of slope stability were applied with the intention of quantify the safety factor of the same. The method used in the stability analyzes was the SRM, implemented in the OPTUM Software, considering different saturation conditions, as follows: soil under natural field saturation condition, soil with 50% degree of saturation, and finally Completely saturated soil. The analysis also took into account the presence of layers of cemented soil and traction cracks present in the upper part of the cliff. The slope was divided into three sections with predominant soils, which were positioned at the base of the intermediate section, and at the top of the cliff, called soil-1, soil-2, and soil-3 respectively. These soils were characterized as clayey sand (SC), silty sand (SM) and poorly graded sand (SP). As for the retention curves, the three soils present bimodal behavior, typical of soils with granulometry of material with micropores and macropores. Finally, the results obtained from these numerical analyzes were initially related to the model of susceptibility produced from the AHP-GIS methodology, concluding that this model is in good agreement, evidenced by the results of the numerical analysis and by the vestiges of Movements observed in the field. The results of the numerical analyzes were also related to the types of mass movements, presenting as an outcome that both geomorphological factors and degrees of saturation result in different types of movements for the characteristic sections of these geomorphologies (cliffs). Verifying in this way the movements suggested in the studies of Santos Jr et al. (2004) and Souza Junior (2013), where three types of profiles with different morphologies and their possible mass movements, toppling, fall of blocks and landslides were related.

Foi comparado o transcriptoma da mucosa do abomaso de 17 ovinos mesti?os ? Santa In?s e ? Dorper, previamente classificados como infectados (resistentes e suscept?veis) e n?o infectados, distribu?dos em dois sistemas de alimenta??o (ad libitum e alimenta??o restrita) em resposta a infec??o por Haemonchus sp., utilizando a tecnologia RNA-Seq. A prepara??o das bibliotecas, o sequenciamento do genoma e a an?lise de dados foram realizadas no Laborat?rio de Biotecnologia Animal - ESALQ, Piracicaba, Brasil. A m?dia de sequ?ncias por amostra antes e depois da filtragem foi de 12.522.573 e 9.626.457, respectivamente, e a m?dia da taxa de mapeamento das leituras filtradas contra o genoma de refer?ncia do ovino Oar_v4.0 foi de 79,66%. Foram identificados como diferencilamente expressos (DE) 421 e 1123 genes quando comparado os animais infectados e n?o infectados, dentro do grupo de alimenta??o restrita e ad libitum, respectivamente. Quando avaliados os infectados inseridos na alimenta??o ad libitum versus alimenta??o restrita, 13 genes foram DE. Quando avaliados os animais resistentes e suscept?veis com efeito fixo de alimenta??o, apenas 36 genes foram DE. E por fim, comparando-se os animais infectados versus os controles tendo a alimenta??o como efeito fixo, foram identificados 881 genes DE. A an?lise de enriquecimento funcional mostrou que alguns termos do Gene Ontology foram significativamente enriquecidos (valor p ajustado<0,05). Nossos achados sugerem que al?m dos genes que participam diretamente do sistema imunol?gico, genes que participam de outras vias biol?gicas como o metabolismo do ?cido araquid?nico, via de sinaliza??o e sistema de complemento s?o essenciais na resposta do hospedeiro a Haemonchus contortus. Al?m disso, a alimenta??o n?o apresentou um efeito significativo no perfil de express?o g?nica dos animais infectados e n?o infectados, mostrando que a diferen?a entre a express?o dos genes foi devido ? infec??o por H. contortus. / The aim of this study was to understand molecular mechanisms underlying host resistance. We compared the abomasal mucosal transcriptome of 17 crossbred ? Santa In?s and ? Dorper lambs, previously classified as infected (resistant and susceptible) and uninfected distributed in two feeding system (ad libitum and restrict feed) in response to Haemonchus sp. infection using RNA-Seq technology. The libraries preparation, genome sequencing and sequence analyses were performed at the Laboratory of Animal Biotechnology - ESALQ, Piracicaba, Brazil. The average of reads per sample before and after filtering was 12.522.573 and 9.626.457, respectively, and the average of mapping rate of filtered reads against to Ovis aries Oar_v4.0 reference genome assembly was 79.66%. 421 and 1123 differentially expressed (DE) genes were identified when compared to infected and uninfected animals, within the restricted and ad libitum feed groups, respectively. When evaluated the infected animals inserted in the ad libitum feed versus restricted feeding, 13 genes were DE. When evaluated the resistant and susceptible animals with fixed feeding effect, only 36 genes were DE. Finally, by comparing infected versus control animals with feed as a fixed effect, 881 DE genes were identified. Functional enrichment analysis showed that some Gene Ontology terms were significantly enriched (adjusted p-value <0.05). Our findings suggest that in addition to genes that participate directly in the immune system, genes that participate in other biological pathways such as arachidonic acid metabolism, signaling pathway and complement system, for example, are essential in the host's response to Haemonchus contortus, generating a greater sheep resistance. In addition, feeding did not have a significant effect on the gene expression profile, showing that the difference between gene expressions was due to H. contortus infection.

Metodologia: 230 coroas de incisivos bovinos foram distribu?das aleatoriamente em 23 grupos (n=10). Ap?s ser realizado o tratamento de superf?cie com ?cido fosf?rico (15 segundos) e Primer Transbond XT (3M Unitek), br?quetes met?licos foram colados ao esmalte com resina Transbond XT (3M Unitek) utilizando 23 protocolos de fotoativa??o de acordo com os fatores ?aparelho fotoativador? (FlashMax P4 ? RMO, Valo Cordless ? Ultradent ou Radii-Cal ? SDI), ?faces fotoativadas? (centro/vestibular; mesial, distal, cervical e incisal; mesial e distal ou cervical e incisal) e ?tempo de fotoativa??o? (2, 3, 4, 6, 20 ou 40 segundos). O ensaio de cisalhamento (100KgF, 1mm/min) foi realizado ap?s o armazenamento das amostras por 4 meses (?gua destilada, 37?C). Utilizando os mesmos protocolos de fotoativa??o, 230 discos de resina (0,1 mm de espessura e 5 mm de di?metro, em m?dia) foram confeccionados para an?lise do GC. Os dados da RUC (MPa) e do GC (%) foram avaliados descritivamente e atrav?s do teste T de Student, da ANOVA one way e do teste de Tukey. As falhas de uni?o foram classificadas de acordo com o ?ndice Remanescente Adesivo (IRA), analisadas descritivamente e atrav?s do teste de Kruskal-Wallis. Resultados: De todos os 23 protocolos, apenas 5 apresentaram valores de RUC clinicamente aceitos de acordo com a literatura. No que diz respeito aos fatores ?faces fotoativadas? e ?tempo de fotoativa??o?, os protocolos do Valo Cordless foram os ?nicos que apresentaram resultados quanto ? RUC estatisticamente semelhantes (p=0,230 e p=0,093, respectivamente). Das compara??es que apresentaram diferen?a estatisticamente significativa (p?0,05) quanto ao fator ?tempo de fotoativa??o? de acordo com a RUC, 66,6% correspondem aos protocolos onde apenas a face central do br?quete foi fotoativada. Ao comparar os grupos onde apenas duas faces foram fotoativadas, aqueles em que o par de faces correspondeu ? mesial e ? distal foram os que resultaram maiores valores de RUC. Quanto ao GC, tendo em vista o fator ?faces fotoativadas?, apenas os resultados dos grupos do FlashMax P4 foram estatisticamente diferentes (p?0,05). O Valo Cordless foi o ?nico aparelho no qual o fator ?tempo de fotoativa??o? n?o afetou de forma estatisticamente significa os valores do GC (p=0,968). E a maioria (66,6%) dos valores mais elevados do GC quando apenas duas faces foram fotoativadas correspondeu ?queles protocolos nos quais tais faces foram a mesial e a distal. Em rela??o ao IRA, houve diferen?a estatisticamente significativa entre os escores (p=0,000), sendo que o escore 2 foi o mais observado (52,6%). Conclus?o: A RUC dos br?quetes met?licos colados ao esmalte e o GC da Transbond XT podem apresentar diferen?as estatisticamente significativas a depender do aparelho fotoativador selecionado e do protocolo de colagem utilizado pelo ortodontista. E sup?e-se que a for?a adesiva entre a resina e o esmalte dent?rio ? maior do que aquela entre o br?quete e a Transbond XT. / Objective: To analyze the effect of different photoactivation protocols on shear bond strength (SBS) of metallic brackets bonded to enamel and the degree of conversion (DC) of an orthodontic resin using three photoactivating devices. Methodology: 230 crowns of bovine incisors were randomly distributed in 23 groups (n = 10). After the surface treatment with phosphoric acid (15 seconds) and Primer Transbond XT (3M Unitek), metal brackets were bonded to the enamel with Transbond XT resin (3M Unitek) using 23 photoactivation protocols according to the factors "photoactivator" (FlashMax P4 ? RMO, Valo Cordless ? Ultradent or Radii-Cal ? SDI), "photoactivated faces" (center/vestibular; mesial, distal, cervical and incisal; mesial and distal or cervical and incisal) and "photoactivation time" (2, 3, 4, 6, 20 or 40 seconds). The shear test (100KgF, 1mm/min) was performed after storage of the samples for 4 months (distilled water, 37?C). Using the same photoactivation protocols, 230 resin discs (0,1 mm thick and 5 mm diameter, on average) were made for DC analysis. The SBS (MPa) and DC (%) data were evaluated descriptively and through Student's T-test, one-way ANOVA and the Tukey test. The union failures were classified according to the Adhesive Remnant Index (ARI), analyzed descriptively and through the Kruskal-Wallis test. Results: Of all 23 protocols, only 5 presented clinically accepted SBS values according to the literature. Regarding the factors "photoactivated faces" and "photoactivation time", the Valo Cordless protocols were the only ones that presented statistically similar SBS results (p=0,230 and p=0,093, respectively). Of the comparisons that presented a statistically significant difference (p?0,05) regarding the factor "time of photoactivation" according to SBS, 66,6% corresponded to the protocols where only the central face of the bracket was photoactivated. When comparing the groups where only two faces were photoactivated, those in which the pair of faces corresponded to the mesial and the distal were the ones that resulted in higher SBS values. Regarding the CG, considering the "photoactivated faces" factor, only the results of the FlashMax P4 groups were statistically different (p?0,05). The Valo Cordless was the only device in which the factor "time of photoactivation" didn?t affect statistically means the values of the DC (p=0,968). And the majority (66,6%) of the highest DC values when only two faces were photoactivated corresponded to those protocols in which such faces were mesial and distal. Regarding ARI, there was a statistically significant difference between the scores (p=0,000), and the score 2 was the most observed (52,6%). Conclusion: The SBS of the metal brackets bonded to the enamel and the DC of the Transbond XT resin may present statistically significant differences depending on the selected photoactivating device and the bonding protocol used by the orthodontist. And it?s assumed that the adhesive force between the resin and the dental enamel is greater than that between the bracket and the Transbond XT.
