Item Tempo de sobrevivência em um modelo estocástico para evolução de espécies(Universidade Federal de Goiás, 2014-02-27) Aguiar Júnior, Dióscoros Brito; Vargas Júnior, Valdivino; http://lattes.cnpq.br/1795859800919467; Vargas Júnior, Valdivino; Gava, Renato Jacob; Silva, Tatiane Ferreira do Nascimento Melo daIn this work ,we will consider two stochastic models for evolution os species. First, births and deaths of species occur with constant probabilities. Each new species is associated with a fitness sampled from the uniform distribution on [0,1]. Every time there is a death event then the type is killed is the one with smallest fitness. We show that there is a sharp phasetransitionwhentheprobabilityislargerthanthedeathprobability.Thesetofspecies with fitness higher than a certain critical value approach an uniform distribution. On the other hand all the species with fitness less than the crital disappear after a finite (random) time. The second model, we consider a stochastic model for species evolution. A new species is born at rateλ and a species dies at rate µ. A random number, sampled from a given distribution F, is associated with each new species and assumed as its fitness, at the time of birth. Likewise the first model, every time there is a death event, the species that is killed is the one with the smallest fitness. We consider the (random) survival time if a species with a given fitness f. We show that the survival time distribution depends crucially on whetherffc where fc is a critical fitness that is computed explicit.Item Caracterização farmacognóstica e atividade antimicrobiana da folha e casca do caule da Myrcia rostrata DC(Universidade Federal de Goiás, 2012-02-17) Alcântara, Guizelle Aparecida de; Paula, José Realino de; http://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4727958Y2; Verde, Giuliana Muniz Vila; http://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4702170Z2; Paula, Joelma Abadia Marciano de; http://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4797707D6The family Myrtaceae in Brazil is one of the most important families, comprising about 23 genera and 130 species. The specie Myrcia rostrata DC. popularly known as "folha miúda" or "guamirim chorão" is commonly found in South American forests and in some units that are part of the Federation Cerrado, as in Goias, Distrito Federal, Mato Grosso and other states. The aim of this study was to establish parameters pharmacognostic for quality control of M. rostrata and analyze the antimicrobial activity of the leaves and stem bark of this species. For this, the macroscopic description and implementation of the sections for microscopic analysis, the plant material was used fresh. As for the post microscopy, determination of volatile substances, total ash and acid insoluble, research and quantification of constituent phytochemicals, obtaining of crude ethanol extract and fractions and essential oil extraction, the shells were dried in an oven with forced circulation at 40 ° C and leaves outdoors. The gas chromatography coupled to mass spectrometry (GC / MS) was used to characterize the chemistry composition of essential oils, the test of serial broth microdilution for antimicrobial activity and Minimal Inhibitory Concentration (MIC) and High Performance Liquid Chromatography (HPLC) to obtain the chromatograms of the aqueous fractions (FAqC) and dichloromethane (FDC) from the stem bark of M. rostrata. The leaves of this species are simple menbranacea consistency, with shiny dark green on the adaxial surface dark green and opaque in the abaxial. Microscopically hypostomaticare present numerous unicellular trichomes have secretory cavities and idioblasts with prismatic crystals. The shells are curved stem and appearance of the outer surface is characterized as thick, fissured and striatum of which have dark-brown color. When examined microscopically is possible to visualize the periderm, sclereids and crystal series. Were detect in the phytochemistry essential oil, tannins, flavonoids and terpenes both the leaves and the bark of the stem. The total phenols content, tannins that precipitate proteins, hydrolysable tannins and flavonoids in the leaves were 7,53% ± 0,14, 4,65% ± 0, 65,39% ± 1,70 and 2,83% ± 0, for the stem bark were 10,06% ± 0,06, 9,60% ± 0,60, 29,53% ± 0,52 and 0,38% ± 0,009. In the analysis of essential oils from six constituencies identified spathulenol (51.39%) and globulol (6.88%) were the major components in the shell, together with the -Caryophyllene these compounds also predominated in the leaves, which were identified 32 constituents. Therefore, the sesquiterpene hydrocarbons and oxygenated sesquiterpenes predominated in the essential oils from leaves and bark of M. rostrata. In the analysis of the antimicrobial activity of essential oil extracted from leaves of M. rostrata showed moderate antibacterial activity with minimum inhibitory concentration (MIC) of 250 mg / mL for Gram (-) Enterobacter aerogenes ATCC 13048 and for all Gram (+) tested, the crude extract of leaves inhibited fungi with MIC 31.25 mg / mL for the species Candida parapsilosis ATCC 22019, Candida parapsilosis 11-a, 02 Candida albicans and Cryptococcus gattii L1, Cryptococcus neoformans ATCC 28957 and Cryptococcus neoformans L2 CIM was 15.62 mg / mL. Fractions of the leaves and stem bark tested showed the lowest minimum inhibitory concentration was FAqC against Cryptococcus neoformans ATCC 28957 (7.81 mg / mL) and Cryptococcus gattii L1 (15.62 mg / mL) and the FDC against Gram (-) Enterobacter aerogenes ATCC 13 048 (23.43 mg / mL) and against Gram (+) Bacillus subtilis ATCC 6633 (93.75 mg / mL).The results contribute to the identification of the species M. rostrata and demonstrate its potential for treating diseases caused by micro-organisms.Item Uso de Seleção de Características da Wikipedia na Classificação Automática de Textos.(Universidade Federal de Goiás, 2012-09-20) Alvarenga, Leonel Diógenes Carvalhaes; Rosa, Thierson Couto; http://lattes.cnpq.br/4414718560764818The traditional methods of text classification typically represent documents only as a set of words, also known as "Bag of Words"(BOW). Several studies have shown good results on making use of thesauri and encyclopedias as external information sources, aiming to expand the BOW representation by the identification of synonymy and hyponymy relationships between present terms in a document collection. However, the expansion process may introduce terms that lead to an erroneous classification. In this paper, we propose the use of feature selection measures in order to select features extracted from Wikipedia in order to improve the efectiveness of the expansion process. The study also proposes a feature selection measure called Tendency Factor to One Category (TF1C), so that the experiments showed that this measure proves to be competitive with the other measures Information Gain, Gain Ratio and Chisquared, in the process, delivering the best gains in microF1 and macroF1, in most experiments. The full use of features selected in this process showed to be more stable in assisting the classification, while it showed lower performance on restricting its insertion only to documents of the classes in which these features are well punctuated by the selection measures. When applied in the Reuters-21578, Ohsumed first - 20000 and 20Newsgroups collections, our approach to feature selection allowed the reduction of noise insertion inherent in the expansion process, and improved the results of use hyponyms, and demonstrated that the synonym relationship from Wikipedia can also be used in the document expansion, increasing the efectiveness of the automatic text classification.Item Desenvolvimento de modelos de QSAR e análise quimioinformática da sensibilização e permeabilidade da pele(Universidade Federal de Goiás, 2014-03-17) Alves, Vinícius de Medeiros; Andrade, Carolina Horta; http://lattes.cnpq.br/2018317447324228; Andrade, Carolina Horta; Ferreira, Elizabeth Igne; Camargo, Ademir J.Repetitive exposure to a chemical agent can induce an immune reaction in inherently susceptible individuals that leads to skin sensitization. Although many chemicals have been reported as skin sensitizers, there have been very few reports analyzing the relationships between their molecular structure and the sensitization potential including the connection to skin permeability, which is widely considered to be mechanistically implicated in sensitization. In this study, we have compiled, curated, and integrated the largest publicly available datasets related to chemically-induced skin sensitization and skin permeability. Unexpectedly, no correlation between sensitization and permeability has been found. Predictive QSAR models have been developed and validated for both skin sensitization and skin permeability using a standardized workflow fully compliant with the OECD guidelines. The classification accuracies of QSAR models discriminating sensitizers from non-sensitizers were 0.68-0.88 when evaluated on several external validation sets. When compared to the predictions generated by the OECD QSAR Toolbox skin sensitization module, our models had significantly higher prediction accuracy for the same sets of external compounds as evaluated by Positive Predicted Rate and Negative Predicted Rate as well as Correct Classification Rate. We have also developed QSAR models of skin permeability measured quantitatively. Cross-species correlation between human and rodent permeability data was found to be low (r²=0.44); thus, skin permeability models were developed using human data only and their external accuracy was q²ext = 0.87 (for 62% of external compounds found within the model applicability domain). Skin sensitization models have been employed to identify putative chemical hazards in the Scorecard database of possible skin or sense organ toxicants that should be regarded as primary candidates for the experimental validation.Item Análise combinatória: uma questão de lógica e linguagens(Universidade Federal de Goiás, 2013-03-01) Alvim, Karina Guerra Cardoso; Souza, Mário José de; http://lattes.cnpq.br/4862963990848505; Souza, Mário José de; Seimetz, Rui; Vieira, Elisabeth Cristina FariaThe objective of this work is to address the Combinatorial Analysis as a theme that can be treated in the classroom, without the utilization of mathematical formulas in problem solving. For this it will presented a method of reasoning that, basing on logic and languages, underscores the importance of: To read, interpret and analyze texts that are presented in the mother tongue; Formulate conjectures, make choices and seek strategies of count; and Make the correct translation between languages maternal and mathematics. Expected to show from this approach that the Combinatorial Analysis, besides its importance in various elds of knowledge, may also be seen by students and teachers as a challenging and stimulating content.Item Influência do tempo de estocagem de leite cru refrigerado sobre a presença de CMP (Caseinomacropeptídeo)(Universidade Federal de Goiás, 2007) Amorim, Henrique Esteves; Mesquita, Albenones José de; http://lattes.cnpq.br/3180029815183858; Nicolau, Edmar Soares; http://lattes.cnpq.br/9601723963736071; Moura, Celso José de; http://lattes.cnpq.br/6006558807438442With the objective to evaluate the influence of the stockage time on the presence of CMP (caseinmacropeptide) in raw milk the raw material after reception for the dairy industrie was cooled, 4 °C, and stored in 20.000 L isothermal horizontal tank. The tank remained sealed up during the 72 hours of stockage and in this period the access to this only for collection of samples with intention was allowed to carry through analyses physicist- chemistries, microbiological (counting psychrotrophics aerobic) and of chromatography in HPLC (for whey detention). After the stockage for 72 hours raw milk was destined to the manufacture of Prato cheese. The Prato cheese was submitted the analyses of humidity, chloride and pH, sensorial income and for the quantitative descriptive analysis. One evidenced that the time of stockage of 72 hours is enough for the indication of false positive of whey presence. To long of the storage time the growth of the counting of psychrotrophics, - 6,29 x 105 1,99 x 105 the whey since these microrganismos are the responsible ones for proteolysis of κ-casein. Proteolysis promoted by psychrotrophics is preoccupying for the dairy industry since it can indicate false positive of fraudulent addition of whey to raw milk besides having an inadequate raw material for production of milky derivatives. The analyses physicist- chemistries and of cheese income Prato show that the cooled raw milk use in the production of related queijo did not modify the quality standards, identity and of market of such product. The quantitative descriptive analysis showed that samples that samples of produced Prato cheese with raw milk cooled storaged by 72 hours can negative influence in the attributes flavor bitter taste and elasticity for proteolysis of the casein. UFC/mL, is correlated estatistically with the evolution of the text ofItem Efeitos de culturas de cobertura na qualidade física do solo sob plantio direto(Universidade Federal de Goiás, 2008-02-22) Andrade, Rui da Silva; Silveira, Pedro Marques da; Stone, Luís Fernando; http://lattes.cnpq.br/0233514913817700The objective of this study was to verify the suitability of S index in the diagnostic of physical quality of Cerrado soils and, based upon it, to determine the effect of cover crop mulches on physical quality of a Dystrophic Red Latosol (Oxisol) under no-tillage. A total of 2364 samples were selected from the soil data base of Embrapa Rice & Beans and Embrapa Cerrados, covering Cerrado soils from Mid-West, North, and Northeast regions of Brazil. Values of S index, defined as the slope of the soil water retention curve at its inflection point, obtained from these samples were correlated to soil bulk density, macroporosity, and total porosity, considering the following textural classes: very clayey, clayey, sandy clay, sandy clay loam, loam/sandy loam e loamy sand/sand. Based on review of literature, critical values were established for the physical attributes that separated, according to the texture, soils with good and poor structural quality and, based upon they, critical values were established for the S index. In order to study the effect of cover crop mulches on soil physical quality, an experiment was carried out under center pivot at Embrapa Rice & Beans, in Santo Antônio de Goiás, GO, in a randomized block design, with eight replications. The treatments consisted of eight cover crops: Brachiaria brizantha; corn associated with B. brizantha; pigeon pea; millet; Panicum maximum; sorghum; Stylosanthes guianensis; and Crotalaria juncea. The first seven crops had been cultivated in summer season since December 2001 and C. juncea since November 2003. In the winter season, after cover crop desiccation, irrigated common bean crop was implemented under no-tillage. In February 2006, soil organic matter content, some soil physical attributes, and soil physical quality measured by S index were determined. This index was highly correlated to the physical attributes, showing to be an adequate indicator of physical quality of Cerrado soils. The limit value of S = 0.045 showed to be adequate to separate soils with good structure and soils with the tendency to be degraded, while values of S ≤ 0,025 indicate physically degraded soils. Cover crops, specially grasses, favored soil aggregation at surface layer. Soil cultivation modified its structure in comparison to native forest, increasing bulk density and reducing macroporosity and total porosity, and hence, reducing soil physical quality. Among the cover crops, pigeon pea, C. juncea, and corn associated with B. brizantha were those that maintained soil surface layer with good physical quality.Item Uma estratégia para a avaliação e evolução de teste funcional de software(Universidade Federal de Goiás, 2012) Arantes, Gilmar Ferreira; Leitão Júnior, Plínio de Sá; http://lattes.cnpq.br/4480334653242457Software Testing is part of software quality assurance activities. It aims to uncover the presence of defects, that can be inserted in various stages of software develop- ment. Several techniques are used in the testing activity, highlighting the functional ones, which derive test requirements from the software specification. The research faces the problem of how to evolve the functional testing strategies with low costs, relative to the amount of test cases needed, without compromising the number of uncovered defects. A systematic review was planned and executed, based on formu- lated questions so as to answer the research problem. Such review supported the definition of a new criterion for functional testing, the Systematic Functional Test with Decision Table Application (TFS-DT), which is an extension of Systematic Software Testing (TFS) and provides joint application of criteria: Partitioning Equi- valence Classes, Boundary Value Analysis and Decision Table. The TFS-DT defines a strategy based on a set of requirements and has a process in order to apply the strategy in a systematic manner. Three empirical studies were applied with promi- sing results compared to TFS: all of them reduces at least half the adequated set without impact on the number of uncovered defects.Item O uso da calculadora simples em sala de aula(Universidade Federal de Goiás, 2013-04-11) Arruda, Dilermano Honório de; Mota, Jesus Carlos da; http://lattes.cnpq.br/8457974658695539; Mota, Jesus Carlos da; Seimetz, Rui; Smith, Ole PeterO objetivo deste estudo é apresentar uma ferramenta que todos possuem, que é fácil de carregar e que portanto tem alcance popular.

This intention was put into practice through a double movement. Firstly, we analyze the conditions under which Brasília was created, so we can understand the relationship between this magazine and the intellectual and political fields in this period of time (chapter I). As a result, we also explore the discourses contained within Brasília as a space of visibility of the pan-lusitanist policy. We also investigate within its various sections (The life of the Brazilian Studies Institute, Critics, Articles, Documents, Chronicles, Notes, Anthologies) the relationship between these discourses and the values and myths concerning Salazarism. Secondly, we analyze these relations through productions which are mainly about the “Atlantic Policy” (chapter II). Thirdly, we investigate historiographic texts which implicitly discuss this matter (chapter III). The examination of these diverse discourses and the lusitanization project of the South Atlantic allow us to notice the intimate relationship between Brazilian and Portuguese academics in their defense of this corporative and authoritarian project, and, fundamentally, in the protection of the Portuguese colonialism in Africa.Item Análise da competitividade da cadeia de produção do feijão-comum: um estudo de caso utilizando a matriz de análise de política (MAP)(Universidade Federal de Goiás, 2013-12-17) Assunção, Paulo Eterno Venâncio; Wander, Alcido Elenor; Wander, Alcido Elenor; Filho, Bento Alves da Costa; Souza, Mauro Caetano deThe common bean is an important component of the diet of the Brazilian people, the main source of vegetable protein consumed by the population. The bean has its own characteristics regarding its production process, which differs from other grains, it is produced in three seasons, which occur in different ways and at different times of the year. Public policies adopted within rural aimed try to develop the productive chain, trying to make it more competitive and more able to compete with other chains. In that sense, the Policy Analysis Matrix (PAM) is an important tool for evaluation of these policies and how these policies can provide the setting conducive to the development chain. The general objective of this research was to analyze the competitiveness of bean production in Goiás using the Policy Analysis Matrix. Data were collected on a property representative in the municipality of Cristalina municipality with higher production within the state, and an agribusiness representative. Sought with these data raise the main costs of the production chain of beans. The results obtained for the three harvests, infer that the productive chain of beans in the first and second crop meets with great difficulties of survival, not being competitive at the international level. The first and second crop have high rates of unprotected, indicating that require investments in the same order so that they can survive profitably. The third season introduces a scenario a little more conducive, but actions need to be taken so that this crop can become more competitive. For culture under study is not competitive enough to have the latest technology, but also public actions that benefit and provide the product competitiveness.Item O número de ouro e construções geométricas(Universidade Federal de Goiás, 2013-03-22) Azevedo, Natália de Carvalho de; Cruz, José Yunier Bello; http://lattes.cnpq.br/8377200040018415; Cruz, José Yunier Bello; Seimetz, Rui; Martins, Ivonildes RibeiroThe golden number and its geometry remote from Ancient Greece. The golden number is a real number that can be represented geometrically by dividing a segment in extreme and mean ratio. It is related to the act of determining a point C on a segment AB in order to obtain equal ratios between AB : AC and AC : CB. Its value is obtained by numerical solution of the quadratic equation obtained from this equality. From ruler and compass constructions of the golden mean other geometric constructions are made: triangles, rectangles, pentagons and spirals. The golden number has been present in arts, architecture and nature for years, and it presented in this work as a tool for study, focusing on presentation to high school students.Item Síntese e avaliação de óxido de ferro suportado em carvão ativado polimérico como catalisador na desidrogenação do etilbenzeno(Universidade Federal de Goiás) Barbosa, Danns Pereira; Rabelo, Denilson; http://lattes.cnpq.br/4961539278604455In this work, activated carbon were synthesized through carbonization of a polymer, containing iron oxides with and without copper. The precursor of activated carbon was a styrene?divinylbenzene copolymer (Sty?DVB) synthesized through suspension polymerization, in the presence of inert diluentes to obtain a macroporous structure. The resin was sulfonated with sulfuric acid, in the presence of dichloroethane. For the synthesis of the supported catalysts, on first it was carried out oxide precipitation in the sulfonated resin and later a thermal treatment to obtain the carbonizated structures. The oxides synthesis were accomplished in three stages: the) incorporation of Fe2+ ions with or without Cu2+ in the resin by ion exchange; b) washing to remove the íons that were not adsorbed; c) coprecipitation in alkaline and oxidant solution. The thermal treatment consisted in calcination of polymer/oxide composite at 250 ºC, carbonization at 900 ºC and activation at 900 ºC with steam. The effect of copper concentration and presence of the support were investigated in the reaction of ethylbenzene dehydrogenation with and without steam. For comparison, bulk catalysts were prepared with the same conditions of coprecipitation of Fe2+ or Cu2+ ions for supported catalysts without the use of sulfonated resin. The materials were characterized by chemical analysis, X rays diffraction, termogravimetric analysis and porosity measurements by nitrogen physical adsorption. It was verified that the polymeric matrix affected the oxide type produced in comparison with coprecipitations in solution. The supported catalysts had better catalytic activities than the bulk and comercial ones because their higher porosities and specfic surface areas. Besides, during the reaction, they presented small tendence sinterization and coke formation. The last property is an intrinsic characteristic of the support based on polymeric activated carbon.Item Revolução científica e nascimento da ciência experimental em Alexandre Koyré(Universidade Federal de Goiás, 2013-08-30) Barbosa, Mohana Ribeiro; Salomon, Marlon Jeison; http://lattes.cnpq.br/0631789010231492This work aims to understand the definition given by Alexandre Koyré for the experimental science of the seventeenth century, exploring the importance of this concept within the historiography of science. Assuming that the opposition made by Koyré of Auguste Comte’s positivism, theoretical conception dominant in the history and philosophy of sciences in the first half of the twentieth century, engenders a new meaning for science and its course. In his work as a historian of science, developed primarily between 1930 and 1961, Koyré formulates precise concepts for various elements considered essential to the history and philosophy of sciences, such as: scientific revolution, experimentation, tools and instruments. I intend to demonstrate the intellectual trajectory and epistemological debates present in the formation of these concepts.Item Avaliação do saneamento ambiental em assentamentos de reforma agrária utilizando o Método de Análise Hierárquica de processos(Universidade Federal de Goiás, 2013-09-13) Barros, Elaine Franciely dos Santos; Baumann, Luis Rodrigo Fernandes; Scalize, Paulo Sérgio; http://lattes.cnpq.br/0957896448117207; Scalize, Paulo Sérgio; Baumann, Luis Rodrigo Fernandes; Hora, Karla Emmanuela Ribeiro; Bernardes, Ricardo SilveiraThe absence or disability of environmental sanitation systems causes serious environmental and social problems . Large portion of the population lives in poor sanitation, primarily those living in rural areas . This fact tailpiece directly to agrarian reform , where the absence of public policies directed to this aspect , lack of technical assistance and insufficient funds for the construction of housing, makes many residents adopt techniques and improper practices that harm your health and the environment . The aim of this study was to evaluate the environmental sanitation conditions in agrarian reform settlements using the Analytic Hierarchy Process ( AHP ) . The method was structured for the analysis of environmental sanitation in rural areas , establishing a hierarchical structure considering the aspects related to sanitation and socioeconomic conditions , determining the weights of criteria through analysis of interviews with experts in the field and elaboration of the form data collection . The application form was held in February 2013 in settlements in the region Pinga - Fogo , municipality of Miners , and settlement Don Carmelo , Caiapônia municipality , both in the state of Goiás After application form , which determined the weights of each criterion analyzed in the area , went to the processing and determination of local priorities and global settlement of each and comparing them . The AHP method allowed visited lots of hierarchy according to the conditions of each sub-criterion (water supply , sewerage and solid waste ) and analysis criteria ( sanitation and socioeconomic conditions ) for settlement and then comparing them . Besides having to prioritization of lots , it was possible to diagnose which were the main criteria for interference in local conditions , which allows for better targeting and prioritization of actions aimed at improving sanitation and hence the quality of life of local community . According to the results, the settlements of the region Pinga - Fogo had better conditions in all sub-criteria and criteria examined , compared with the settlement Don Carmelo.Item Troca de Emaranhamento e Teletransporte Controlado no contexto de rotações de Faraday fotônicas(Universidade Federal de Goiás, 2011-03-04) Bastos, Wellison Peixoto; Cardoso, Wesley Bueno; Baseia, Basilio; http://lattes.cnpq.br/5804506385505435; Baseia, Basilio; Cardoso, Wesley Bueno; Mizrahi, Salomon Sylvain; Fonseca, Tertius Lima daTaking advantage of the Faraday rotations that occur in a photonic cristal placed in an optical cavity with low quality factor, we proposed two schemes to obtain the swapping of entanglement of atomic states, useful in quantum communication and quantum computation. They employ three-level atoms in a -configuration, a linearly polarized photon source, a single detector, and a quarter wave plate. Three (four) cavities are used in the first (second) scheme. An additional scheme was also proposed to obtain controlled teleportation of superposition states, partial controlled teleportation of entangled states and controlled teleportation of entanglement. In all schemes we have included the imperfections that affect the system, such as transmission and coupling of photons in optical components, the fraction of photons with a desired polarization, the quantum efficiency of single photon detection, the effective solid angle where the photon are collected, and the rate of emitted photons by the source. Under these realistic conditions we estimate the success probability of each proccess, including the time spent for its realization.Item Avaliação citogenética e molecular de indivíduos ocupacionalmente expostos aos agrotóxicos(Universidade Federal de Goiás, 2014-02-28) Batista, Mariana Pedrosa; Silva, Daniela de Melo e; http://lattes.cnpq.br/9895211901348365Rural workers are constantly exposed to pesticides they use on crops, and this exposure may be responsible for genetic damage causing a health risk. A problem with the use of pesticides is the genotoxicity, which can lead to the onset of disease. Little is known about the relationship between genotoxicity and the variation of genetic polymorphisms of xenobiotic metabolism that may modify individual susceptibility to the possible genotoxic effects of pesticides. Therefore, there is a need to study genes as glutathione-S-transferase mu (GSTM1) and theta glutathione S-transferase (GSTT1) encoding detoxification enzymes of genotoxic compounds. Another important assessment in individuals exposed to pesticides is the presence of chromosomal translocation t(14;18) (q31,q21), which can be investigated at the molecular level. Thus, this study evaluated the polymorphisms of GSTM1 and GSTT1 genes in 120 individuals occupationally exposed to pesticides and 115 controls (without exposure to pesticides), by real-time PCR. The frequencies of GSTM1 and GSTT1 genotypes were found in 49 % and 18 %, respectively in the exposed group and 37 % and 18 %, respectively, for the control group. It has been found that there is a greater possibility of poisoning in workers who have null genotypes. There was no statistically significant correlation between the increased risk of intoxication and alcohol consumption, smoking and use of PPE. In addition, 29 workers exposed to pesticides for more than 15 years and with null genotypes in GSTT1 and / or GSTM1, were evaluated for the presence of the t (14;18)(q31, q21), in 100 nuclei, by fluorescent in situ hybridization (FISH) . The translocation was observed in only one individual, which may have been caused by prolonged exposure to pesticides, increasing age or alcohol consumption. Thus, the study of genetic polymorphisms and translocations as biomarkers of susceptibility is of fundamental importance in understanding the processes involved in genotype distribution mutagenesis and carcinogenesis and could help minimize the risks for susceptible individuals who are exposed to pesticides.Item A arte além da razão: a tragédia na reflexão do jovem Nietzsche(Universidade Federal de Goiás, 2014-02-24) Batista, Walquiria Pereira; Lopes, Adriana Delbó; http://lattes.cnpq.br/6600189022732543; Lopes, Adriana Delbó; Silva, Adriano Correia; Oliveira, Roberto Charles Feitosa deThe starting point of this study is the examination of tragic art in Nietzsche’s reflection about culture, having his first book The Birth of Tragedy as main line. An intrinsic relation between art and life is noticed in the opposition which the philosopher establishes between a tragic culture and a theoretical culture, in a way that the first is seen as the ideal terrain of art, while the latter is considered a promoter of the artificialized arts of the modern era. The objective is to examine the metaphysical impulses which art has as a substratum in tragic culture and, at the same time, to identify the superposition of reason inaugurated by Socrates as something harmful to the instincts, which would exterminate from art its original, solely artistic element. With these notions, the intention is to study Nietzsche’s Apollinian- Dionysian conception of art, in dialogue with authors of Greek and German drama, identifying contrasts and communions. Art projected on the principle of reason would have its mark in Euripides’ aesthetic Socratism, in Aristotle’s primacy of action and catharsis, in Lessing’s Enlightenment dramaturgy, in Schiller’s expressions of liberty and would resonate in the recitative of the opera in the service of distraction. On the other hand, the splendor of the tragic era lies in the tragedies of Aeschylus and Sophocles, in the hero’s Apollinian- Dionysian dichotomy, exemplified in Prometheus and in the two Oedipusses. Myth and music are seen as fundamental and inseparable components of art sprouted in a tragic culture, capable of establishing an unconscious relationship with the audience. These are the premises to understand Nietzsche’s affinities with Wagner, in the expectation of a renaissance of myth and music as reawakening of the tragic spirit in German genius.Item Ciclos limite para a equação de Abel generalizada(Universidade Federal de Goiás, 2009-10-30) Belisário, Hugo Leonardo da Silva; Garcia, Ronaldo Alves; http://lattes.cnpq.br/5680428710939826In this work we conducted a study on the equations of the type dx dt = nå i=0 ai(t)xi; (A) where ai 2 C1, i = 0; ;n and 0 t 1. An equation of the form (A) is called a generalized Abel equation. Our study refers to the problem proposed by C. Pugh: There is a natural number N depending only on n, such that the equation (A) has at most N limit cycles? Initially we study the problem of C. Pugh for n = 1 and n = 2, for which the equation (A) has at most one and two limit cycles, respectively. For n = 3, A. Lins Neto shows that if a3(t) does not change sign on [0;1], then the equation (A) has at most three limit cycles. Also A. Lins Neto shows that, given a natural number l, it is possible to construct an equation of the form (A) with n = 3 that has at least l limit cycles. Still for n = 3, A. Gasull and J. Llibre study the problem of C. Pugh considering that a2(t) does not change sign on [0;1], and M. J. Alvarez, A. Gasull and H. Giacomini also study the problem of C. Pugh considering that there are real numbers a and b such that aa3(t)+ba2(t) does not change sign on [0;1] and a1(t) = a0(t) = 0. Besides this, we study some more general results studied by A. Gasull and A. Guillamon.Item Efeito do estresse hídrico no metabolismo de gabirobeira(Universidade Federal de Goiás, 2012-03-21) Belo, Emiliane dos Santos; Silva, Samuel Mariano da; http://lattes.cnpq.br/4333570201713380; Neto, Antônio Paulino da Costa; Neto, Antônio Paulino da Costa; Assunção, Hildeu Ferreira da; Paiva, RenatoAs respostas das plantas ao déficit hídrico são complexas, envolvendo mudanças adaptativas e/ou efeitos deletérios. Os danos causados por estresses às plantas podem ser reversíveis ou irreversíveis. O objetivo deste trabalho foi avaliar a tolerância da gabirobeira (Campomanesia spp) ao estresse hídrico e hipoxia de raízes durante 18 dias. Avaliou-se o conteúdo de matéria fresca, seca, água, AST, sacarose, amido, proteínas bruta, insolúvel, solúvel e aminoácidos de folhas e raízes, além dos parâmetros de crescimento como TCR, TCA, TAL, diâmetro do colo, comprimento e área de raízes. As gabirobeiras sob estresse hídrico apresentaram redução no conteúdo de água, prejuízos na produção de biomassa de folhas e raízes, redução no conteúdo de AST, amido e no conteúdo de aminoácidos. Sob hipoxia, exibiram prejuízos na alocação de fotossintatos da parte aérea para as raízes, e por isso armazenam grandes quantidades de amido, os maiores prejuízos ocorreram em raízes. As estratégias de sobrevivência ao estresse hídrico incluem a remobilização de carboidratos solúveis e de reserva da parte aérea para as raízes permitindo assim que as gabirobeiras escapassem da seca. Sob hipoxia o potencial hídrico das folhas foi sustentado com carboidratos solúveis oriundos da remobilização do amido, provavelmente também houve síntese e degradação de polipeptídeos e enzimas em raízes devido a mudança do metabolismo aeróbio para anaeróbio.
