Al?m das altera??es hormonais e reprodutivas, ? comum na SOP a presen?a de fatores de risco para desenvolvimento de doen?as cardiovasculares (DCV) como diabetes mellitus, resist?ncia ? insulina (RI), obesidade visceral, inflama??o cr?nica de baixo grau e dislipidemia. Devido ? elevada frequ?ncia da obesidade associada ? SOP, a perda de peso ? considerada como o tratamento de primeira linha para a s?ndrome por melhorar as altera??es metab?licas e normalizar os andr?genos s?ricos, restaurando a fun??o reprodutiva destas pacientes. Objetivos: avaliar os marcadores inflamat?rios e a RI em mulheres com SOP e ovulat?rias saud?veis com diferentes estados nutricionais e como os par?metros inflamat?rios e hormonais se apresentam ap?s a perda de peso, atrav?s da restri??o cal?rica nas portadoras da s?ndrome. M?todos: O fator de necrose tumoralalfa (TNF-?), a interleucina-6 (IL-6) e a prote?na c-reativa (PCR) foram avaliados em amostras de soro de 40 mulheres em idade reprodutiva. Na primeira fase do estudo, as volunt?rias foram divididas em quatro grupos: Grupo I (n?o eutr?ficas com SOP, n=12); Grupo II (n?o eutr?ficas sem SOP, n=10), Grupo III (eutr?ficas com SOP, n=08) e Grupo IV (eutr?ficas sem SOP, n=10). A categoriza??o dos grupos foi realizada pelo ?ndice de massa corporal (IMC), de acordo com a organiza??o mundial de sa?de (OMS) em n?o eutr?fica, mulheres com IMC ? 25 (kg/m?) e eutr?ficas, IMC entre 18,9-24,9 (kg/m?). A RI foi determinada atrav?s do ?ndice HOMA-IR. Na segunda fase do estudo foi realizada uma interven??o nutricional controlada e os par?metros inflamat?rios foram avaliados em 21 mulheres sobrepeso e obesas com SOP, antes e depois da perda de peso. Todas as pacientes receberam uma dieta hipocal?rica com redu??o de 500 kcal/dia do consumo habitual com concentra??es padr?o de macronutrientes. Resultados: Fase 1: pacientes com SOP apresentaram n?veis aumentados da PCR (p<0,01) e HOMA-IR (p<0,01). Quando divididas por IMC, tanto o grupo n?o eutr?fico com SOP (I) quanto eutr?fico com SOP(III) apresentou n?veis aumentados de PCR (I=2,35?0,55mg/L e III= 2,63?0,65mg/L; p<0,01) e HOMA-IR (I= 2,16?2,54 e III= 1,07?0,55; p<0,01). N?o foram encontradas diferen?as de TNF-? e IL-6 entre os grupos. Fase 2: Ap?s a perda de peso de 5% do peso inicial ocorreu uma redu??o em todos os n?veis s?ricos dos componentes do perfil inflamat?rio avaliados, PCR (154.75 ? 19.33) vs (78.06 ? 9.08), TNF- ? (10.89 ? 5.09) vs (6.39 ? 1.41) e IL6 (154.75 ? 19.33) vs (78.06 ? 9.08) (p < 0.00) em associa??o com a melhora de alguns par?metros hormonais avaliados. Conclus?o: A SOP contribuiu para o surgimento da inflama??o cr?nica e das altera??es no metabolismo da glicose atrav?s do aumento da PCR, da insulina e do HOMA-IR, independente do estado nutricional e a perda de peso melhoraram o estado inflamat?rio e o perfil hormonal das pacientes avaliadas. / The polycystic ovary syndrome (PCOS) is considered the most common endocrine disorder in reproductive age women, with a prevalence ranging from 15 to 20%. In addition to hormonal and reproductive changes, it is common in PCOS the presence of risk factors for developing cardiovascular disease (CVD) and diabetes mellitus, insulin resistance (IR), visceral obesity, chronic low-grade inflammation and dyslipidemia. Due to the high frequency of obesity associated with PCOS, weight loss is considered as the first-line treatment for the syndrome by improving metabolic and normalizes serum androgens, restoring reproductive function of these patients. Objectives: To evaluate the inflammatory markers and IR in women with PCOS and healthy ovulatory with different nutritional status and how these parameters are displayed after weight loss through caloric restriction in with Down syndrome. Methods: Tumor necrosis factor-alpha (TNF-?), interleukin-6 (IL-6) and C-reactive protein (CRP) were assessed in serum samples from 40 women of childbearing age. The volunteers were divided into four groups: Group I (not eutrophic with PCOS, n = 12); Group II (not eutrophic without PCOS, n = 10), Group III (eutrophic with PCOS, n = 08) and Group IV (eutrophic without PCOS, n = 10). The categorization of groups was performed by body mass index (BMI), according to the World Health Organization (WHO) does not eutrophic, overweight and obesity (BMI> 25 kg / m?) and normal weight (BMI <24.9 kg / m?). IR was determined by HOMA-IR index. In the second phase of the study a controlled dietary intervention was performed and inflammatory parameters were evaluated in 21 overweight and obese women with PCOS, before and after weight loss. All patients received a low-calorie diet with reduction of 500 kcal / day of regular consumption with standard concentrations of macronutrients. Results: Phase 1: PCOS patients showed increased levels of CRP (p <0.01) and HOMAIR (p <0.01). When divided by BMI, both not eutrophic group with PCOS (I) as eutrophic with PCOS (III) showed increased levels of CRP (I = 2.35 ? 0,55mg / L and 2.63 ? III = 0,65mg / L; p <0.01) and HOMA-IR (I = 2.16 ? 2.54 and III = 1.07 ? 0.55; p <0.01). There were no differences in TNF-? and IL-6 between groups. Step 2: After the weight loss of 5% of the initial weight was reduced in all of the components of serum assessed inflammatory profile, PCR (154.75 ? 19:33) vs (78.06 ? 8.9) TNF ? (10.89 ? 5.09) vs (6:39 ? 1:41) and IL6 (154.75 ? 19:33) vs (78.06 ? 08.09) (p <0:00) in association with improvement some hormonal parameters evaluated. Conclusion: PCOS contributed to the development of chronic inflammation and changes in glucose metabolism by increasing CRP, insulin and HOMA-IR, independent of nutritional status. The weight loss, caloric restriction has improved the inflammatory condition and hormonal status of the evaluated patients.

Durante a usinagem dos blocos de zirc?nia para diversos tipos de implantes odontol?gicos, grande parte do material ? desprendida na forma de p?, que posteriormente ? descartado. A zirc?nia tetragonal estabilizada com 3% em mol de ?tria (Y-TZP) possui uma variedade de aplica??es na ?rea de engenharia e biom?dica devido ? sua ?tima combina??o de resist?ncia, tenacidade ? fratura, condutividade i?nica e baixa condutividade t?rmica. Al?m do dano para o meio ambiente, o desperd?cio deste material resulta em preju?zo financeiro, refletindo em elevado custo final no tratamento para os pacientes. Os materiais de partida utilizados neste trabalho foram dois diferentes p?s do sistema cer?mico ZrO3-Y2O3: zirc?nia comercial nanoparticulada e res?duo de zirc?nia microparticulado. Os p?s foram conformados por prensagem uniaxial e isost?tica e em seguida sinterizadas a 1500, 1550 e 1600 ?C, durante 1 hora. As t?cnicas de granulometria a laser, difra??o de raios X (DRX), e dilatometria foram utilizadas para caracteriza??o do p?.

During the machining of blocks of zirconia to several types of dental implants, most of the material is loosened as a powder, which is subsequently discarded. The stabilized tetragonal zirconia with 3% yttria (Y-TZP) mol boasts a variety of applications in engineering, and biomedical, because of its great combination of strength, fracture toughness, ionic conductivity and low thermal conductivity. Besides the damage to the environment wasting of the material resulting in financial loss, reflecting the high final cost of medical treatment for patients. The starting materials used in this work were two different powders ZrO3-Y2O3ceramic system: commercial zirconia nanoparticulate and microparticulate zirc?nia residue. The powder was uniaxially and isostatically pressed and then sintered at 1500, 1550 and 1600 ? C for 1 hour. The techniques of laser granulometry, X-ray diffraction (XRD) and dilatometry were used for powder characterization. After sintering were performed density and porosity tests, X-ray diffraction (XRD), Flexural strength, microhardness and fracture toughness analysis, and scanning electron microscopy (SEM). Samples compacted via isostatic pressing showed values less than 0.78% porosity and demonstrated greater effectiveness compared to uniaxial compression. Was observed in X-ray diffra ction, that with increasing temperature, the intensity of the peaks of monoclinic phase is decreased. The sintering temperature moderately has influenced on the microhardness of samples, showing small increases in hardness to temperature of 1600 ? C. The flexural strength of zirconia residue increases with increasing sintering temperature for both routes of compression, showing the best values for isostatic compression.

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.

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.
