Com isso, objetivou-se com este trabalho estimar os par?metros da curva de postura, utilizando os modelos de polin?mios segmentados e Wood (1967); e estimar par?metros gen?ticos e fenot?picos dos par?metros do modelo de polin?mios segmentados, assim como a tend?ncia gen?tica dos mesmos. Foram utilizados dados da produ??o de ovo semanal das 25 at? 64 semanas de idade provenientes de 2.398 aves de uma linha f?mea de frangos de corte. As curvas de postura foram ajustadas utilizando os modelos de polin?mios segmentados e Wood (1967). O modelo de polin?mios segmentados ? constitu?do pelos par?metros ?xp?- idade das aves ao pico de postura, ?P?- n?vel de produ??o no pico, ?s? - taxa de decr?scimo semanal na produ??o de ovos ap?s o pico, e ?t? - tempo entre o in?cio e o pico de postura. O modelo de Wood ? constitu?do pelos par?metros ?a? - taxa de produ??o inicial, ?b? taxa de acr?scimo at? o pico de produ??o, e ?c? taxa de decr?scimo ap?s o pico de produ??o. As estimativas das m?dias dos par?metros das curvas foram realizadas utilizando o PROC MEANS do SAS. A estima??o dos componentes de covari?ncias, herdabilidades, correla??es e os valores gen?ticos para os par?metros da curva de postura de polin?mios segmentados foram obtidas utilizando o ?software? MTDFREML e as tend?ncias gen?ticas por meio do PROC REG do SAS. A linhagem avaliada apresentou um pico de postura ?s 30,43 semanas de idade, sendo o n?vel de postura de 0,746 ovo/aves/dia, com uma m?dia de 3,08 semanas do in?cio da postura at? o pico de postura e a taxa de persist?ncia foi de 0,014 ovo/ave/semana. As m?dias estimadas para os par?metros do modelo de Wood (1967) foram de 0,0003 para taxa de produ??o inicial 2,9398 para taxa de acr?scimo de produ??o at? o pico e de 0,0767 para taxa de decr?scimo de produ??o ap?s o pico postura. As curvas ajustadas para os modelos de polin?mios segmentados e Wood (1967) permitiram evidenciar um baixo n?vel de produ??o no pico de postura. O modelo de polin?mios segmentados superestimou a persist?ncia ap?s o pico de postura e o modelo de Wood (1967) subestimou o final da produ??o. As m?dias das herdabilidades foram de baixa a m?dia magnitudes, 0,25 (xp), 0,18 (P), 0,17 (s) e 0,10 (t). Estes resultados indicam que a sele??o para o par?metro ?xp? teria uma melhor resposta que para os demais par?metros. As correla??es entre o par?metro ?t? e os demais par?metros da curva foram positivas variando de 0,21 at? 1,00. Essas correla??es indicam que os animais com um maior tempo entre in?cio e pico de postura tendem a apresentar uma maior idade ao pico de postura, maior n?vel de produ??o e maior queda de produ??o p?s-pico. As correla??es foram negativas entre os par?metros ?s? e ?xp? e ?s? e ?P? apresentando-se menor entre ?s? e ?xp? (-0,17) e maior entre ?s? e ?P? (-0,91), indicando que um aumento no n?vel de produ??o e idade ao pico de produ??o acarretaria uma menor queda de produ??o de ovos p?s-pico. Podemos constatar que pode ser promovido ganho gen?tico para os par?metros da curva de produ??o de ovos, por?m a sele??o para um aumento do n?vel de produ??o poder? levar a um aumento na idade ao pico de postura. Assim como, aves mais precoces ao pico poder?o apresentar menor persist?ncia. / Disserta??o (Mestrado) ?

Thus, the aim with this study was to estimate the parameters of the curve approach, using models of segmented polynomials and Wood (1967) and to estimate genetic and phenotypic parameters of the model parameters of segmented polynomials, as well as the genetic tendency of them. It had been used data from the weekly egg production from 2,398 birds in a line of female broilers, aging from 25 to 64 weeks. The curves of posture were adjusted using the models of segmented polynomials and Wood (1967). The segmented polynomial model consists of parameters "xp" - the peak age of the birds in attitude, "P" - at peak production level, "s"- a weekly rate of decrease in egg production after peak, and ?t? - time between onset and peak position. The parameters of the Wood model consist of "a"- rate initial production," b "rate of increase until the production peak, and "c" rate of decline after peak production. Estimates of means of parameters were performed using SAS PROC MEANS. Estimation of covariance components, heritability?s, correlations and breeding values for the parameters of the curve posture segmented polynomial were obtained using the software MTDFREML and genetic trends by PROC REG of SAS. The strain studied showed a peak position at 30.43 weeks of age, the level of posture of 0.746 egg / poultry / day, with an average of 3.08 weeks of posture to the peak position and the rate of persistence was 0.014 eggs / bird / week. The estimated averages for the parameters of the model of Wood (1967) was 0.0003 for rate initial production rate of 2.9398 for increased production to peak and 0.0767 for rate of decline of production after the peak position . The fitted curves for the models of segmented polynomials and Wood (1967) have highlighted a low level of production at peak production. The segmented polynomial model overestimated the persistence after the peak position and the model of Wood (1967) underestimated the final production. The heritability?s means were low to medium magnitude, 0.25 (xp), 0.18 (P), 0.17 (s) and 0.10 (t). These results indicate that selection for the parameter "xp" would have a better response than for the other parameters. The correlations between the parameter "t" and the other parameters of the curve were positive ranging from 0.21 to 1.00. These correlations indicate that animals with a longer time between onset and peak position tend to have a higher age at peak position, the highest level of production and greater decrease in post-peak production. Were negative correlations between the parameters "s" and "xp" and "s" and "P" presenting lower between "s" and "xp" (-0.17) and higher in "s" and "P" (-0.91), indicating that an increase in production level and age at peak production would result in a smaller drop in egg production after peak. It has been noted that genetic gains can be obtained for the curve parameters for egg production, but a selection focused on an increased level of production could lead to an increase in age at peak production. Just as birds that present earlier peak may have lower persistence.

No semi?rido do Nordeste brasileiro sabe-se que h? predomin?ncia de d?ficit h?drico, por?m pouco se conhece sobre tend?ncias em s?ries climatol?gicas da perda conjunta de ?gua por evapora??o e transpira??o (evapotranspira??o). Por isso, neste trabalho procurou-se analisar se h? ind?cios de aumento e/ou diminui??o no regime da evapotranspira??o de refer?ncia (ETo), nas escalas mensal, anual e interdecadal no polo irrigado das localidades de Juazeiro, BA (9?24?S; 40?26?W e 375,5m) e Petrolina, PE (09?09?S, 40?22?W e 376m), sendo essa an?lise o objetivo principal. De posse dos dados meteorol?gicos di?rios, disponibilizados pela EMBRAPA Semi?rido, no per?odo de 01.01.1976 a 31.12.2014, estimou-se a ETo di?ria utilizando-se o m?todo padr?o de Penman-Monteith (EToPM) parametrizado por Smith (1991). Outros m?todos de estimativas mais simplificados foram calculados e comparados ? EToPM, sendo: Radia??o Solar (EToRS), Linacre (EToL), Hargreaves e Samani (EToHS) e o m?todo do Tanque Classe A (EToTCA). As principais an?lises estat?sticas foram os testes n?o param?tricos de homogeneidade (Run), de tend?ncia (Mann-kendall), magnitude da tend?ncia (Sen) e detec??o de in?cio da tend?ncia (Mann-Whitney), a signific?ncia estat?stica adotada foi de 5 e/ou 1%. A t?cnica de An?lise de Vari?ncia - ANOVA foi aplicada para averiguar se h? diferen?a significativa nas m?dias interdecadais. Para efeitos comparativos entre os m?todos de ETo, foram utilizados a correla??o (r), o teste t-student e Tukey aos n?veis de 5% de signific?ncia. E por fim, as estat?sticas de Willmott et al. (1985) foi utilizada para avaliar o ?ndice de concord?ncia e de desempenho dos m?todos simplificados comparados ao m?todo padr?o. Obteve-se como principais resultados que houve diminui??o na s?rie temporal da EToPM nos per?metros irrigados de Juazeiro, BA e Petrolina, PE, significativos respectivamente a 1 e 5%, com uma magnitude anual de -14,5 mm (Juazeiro) e -7,7 mm (Petrolina) e in?cio da tend?ncia em 1996. Os m?todos de melhor concord?ncia com a EToPM foi a EToRS com desempenho muito bom, nas duas localidades, seguido pelo m?todo da EToL com desempenho bom (Juazeiro) e mediano (Petrolina). A EToHS obteve o pior desempenho (p?ssimo), para as duas localidades. ? sugerido neste que a diminui??o da EToPM pode est? associado ao aumento das ?reas agr?colas irrigadas e da constru??o do lago de Sobradinho ? montante dos per?metros. / The variability / climate change has generated great concern worldwide, is one of the major issues as global warming, which can is affecting the availability of water resources in irrigated perimeters. In the semiarid region of Northeastern Brazil it is known that there is a predominance of drought, but it is not enough known about trends in climate series of joint water loss by evaporation and transpiration (evapotranspiration). Therefore, this study aimed to analyze whether there is increase and / or decrease evidence in the regime of reference evapotranspiration (ETo), for the monthly, annual and interdecadal scales in irrigated polo towns of Juazeiro, BA (9 ? 24'S, 40 ? 26'W and 375,5m) and Petrolina, PE (09 ? 09'S, 40 ? 22'W and 376m), which is the main analysis objective. The daily meteorological data were provided by EMBRAPA Semi?rido for the period from 01.01.1976 to 31.12.2014, estimated the daily ETo using the standard method of Penman-Monteith (EToPM) parameterized by Smith (1991). Other methods of more simplified estimatives were calculated and compared to EToPM, as the ones following: Solar Radiation (EToRS), Linacre (EToL), Hargreaves and Samani (EToHS) and the method of Class A pan (EToTCA). The main statistical analysis were non-parametric tests of homogeneity (Run), trend (Mann-kendall), magnitude of the trend (Sen) and early trend detection (Mann-Whitney). The statistical significance adopted was 5 and / or 1%. The Analysis of Variance - ANOVA was used to detect if there is a significant difference in mean interdecadal mean. For comparison between the methods of ETo, it were used the correlation test (r), the Student t test and Tukey levels of 5% significance. Finally, statistics Willmott et al. (1985) statistics was used to evaluate the concordance index and performance of simplified methods compared to the standard method. It obtained as main results that there was a decrease in the time series of EToPM in irrigated areas of Juazeiro, BA and Petrolina, PE, significant respectively at 1 and 5%, with an annual magnitude of -14.5 mm (Juazeiro) and -7.7 mm (Petrolina) and early trend in 1996. The methods which had better for better agreement with EToPM were EToRS with very good performance, in both locations, followed by the method of EToL with good performance (Juazeiro) and median (Petrolina). EToHS had the worst performance (bad) for both locations. It is suggested that this decrease of EToPM can be associated with the increase in irrigated agricultural areas and the construction of Sobradinho lake upstream of the perimeters.

N?o houve, no entanto, precau??es quanto ao uso dos recursos naturais utilizados como fonte de mat?ria prima para a Ind?stria. Desta maneira investigou-se a respeito de ind?cios de altera??es micrometeorol?gicas associadas ? Ind?stria de Cer?mica Estrutural nos elementos meteorol?gicos em algumas ?reas do Nordeste do Brasil. Para verificar se as vari?veis micrometeorol?gicas: precipita??o, evapotranspira??o, radia??o, velocidade do vento, umidade, e temperatura m?xima e m?nima, referentes ao per?odo de 1980 a 2013, apresentavam tend?ncias, utilizou-se o Teste de Mann Kendall; e para calcular os ?ndices de extremos clim?ticos utilizou-se o conjunto de dados para ?ndices de Extremos Clim?ticos - RClimDex. Foram identificados cinco polos, nos quais verificouse haver tend?ncias negativas para precipita??o, temperatura m?nima, umidade relativa e vento. E tend?ncias positivas para as vari?veis temperatura m?xima, evapotranspira??o e radia??o solar. Detectou-se tend?ncia em todos os polos, com exce??o da temperatura m?nima para o polo P2 (que apresenta maior n?mero de cer?micas). Identificou-se, ainda, tend?ncia para os ?ndices de extremos clim?ticos de Rx1day, R99p, Txn, Tnx, Tn10p, Tx10p, Txx e Tnn. Com tend?ncias positivas de extremos de temperatura para os polos estudados, com exce??o do polo P1 que obteve tend?ncia decrescente, indicando diminui??o dos valores m?ximos da m?nima; e do polo P2 que n?o apresentou tend?ncia para a temperatura m?nima e para os ?ndices de Tnn e Tnx e RX5day. Comportamentos adversos podem estar associados a a??es antr?picas da regi?o, especificamente ? intensa atividade ceramista. Por?m, n?o se pode afirmar categoricamente, que esse comportamento est? associado somente as a??es antr?picas, visto que pode estar sob influ?ncia de diversos agentes do clima. / In recent years the Industrial sector of red ceramic has developed representatively with the implantation of micro and small Ceramics companies throughout Brazil. There were, however, no precautions regarding the use of the natural resources used as raw material source for the Industry. In this way, we investigated the indications of micrometeorological alterations associated with the Structural Ceramics Industry in the meteorological elements in some areas of the Northeast of Brazil. In order to verify if the micrometeorological variables: precipitation, evapotranspiration, radiation, wind speed, humidity, and maximum and minimum temperature, referring to the period from 1980 to 2013, presented tendencies, the Mann Kendall test was used; And to calculate the indexes of climatic extremes the Data Set for Indexes of Climatic Extremes - RClimDex was used. Five poles were identified, in which there were negative trends for precipitation, minimum temperature, relative humidity and wind. And positive trends for the variables maximum temperature, evapotranspiration and solar radiation. A tendency was detected at all poles, with the exception of the minimum temperature for the P2 pole (which has the highest number of ceramics). A trend was also identified for the indexes of climatic extremes of Rx1day, R99p, Txn, Tnx, Tn10p, Tx10p, Txx and Tnn. With positive trends of temperature extremes for the studied poles, with the exception of the pole P1 that obtained a decreasing tendency, indicating decrease of the maximum values of the minimum; And the P2 pole which showed no tendency towards the minimum temperature and for the Tnn and Tnx and RX5day indices. Adverse behaviors may be associated with anthropogenic actions in the region, specifically intense ceramist activity. However, it can not be said categorically that this behavior is associated only with anthropic actions, since it may be under the influence of several agents of the climate.

After presenting the researches relating Winnicott's work with the Education, some relevant concepts are presented of his theory, such as the genesis of antisocial behavior, environmental sustainability, activity play, as well as his explanation that causes humans to share the world culture. Supported in the author's view about lying, stealing and destructiveness in cases of school routine. This reserch goes to show the way these concepts can help teachers to reflect on the problems of antisocial tendency (delinquency) in different school environments offered and can modify some practices with these children. This work differentiates therapeutic work of teaching, trying to present these concepts in a language that approaches to the next universe theory and practice of educators. Much of the recent research in the field of psychology consider aggressiveness, delinquency and antisocial tendency as processes that arise when the child is already in school and not when they re a baby. Psychoanalysis as a scientific psychology that offers a theory of emotional development that recognizes unconscious processes in the large field of determinations of actions, feelings and thoughts of human beings, it also offers one of the antisocial behavior both in terms of intrapsychic determinations with its genesis in the initial care of the baby and the relationship with the environment. In this sense it is intended to show how the notions of being and Winnicott continued to be, the development of the relationship of dependence to independence, as well as the differentiation of the various types of integration of individuals, may not only explain aggressive behavior in the school environment as well as offer opportunities for reflection and actions of care and prevention of antisocial behavior with the main focus on this problematic attitudes . / Nesta pesquisa procura-se apresentar as contribui??es de Winnicott para a compreens?o da tend?ncia antissocial nos ambientes escolares e educacionais. Depois de retomar as pesquisas relacionando a obra de Winnicott ? Educa??o, s?o analisados conceitos relevantes de sua teoria tais como: a g?nese da atitude antissocial, a sustenta??o ambiental e a atividade do brincar, assim como sua explica??o sobre o que leva o ser humano a compartilhar o mundo da cultura,enquanto expans?o da ?rea do brincar. Apoiado na vis?o do autor sobre a mentira, o roubo e a destrutividade como rea??es ? depriva??o ambiental, procura-se mostrar de que maneira essas concep??es podem auxiliar os educadores a refletir sobre os problemas da tend?ncia antissocial, nos diversos ambientes escolares, e poder modificar poss?veis atitudes no dia a dia com estas crian?as. Dirigida a educadores, esta pesquisa diferencia o trabalho terap?utico do pedag?gico, procurando apresentar essas concep??es psicanal?ticas numa linguagem e abordagem pr?xima ao universo te?rico e pr?tico dos educadores. A teoria psicanal?tica, do ponto de vista de Winnicott, oferece uma compreens?o do processo de desenvolvimento afetivo que pode ser ?til para o trabalho dos educadores, uma vez que pensa esse desenvolvimento ,bem como seus desvios, em termos das rela??es de depend?ncia, sustenta??o e comunica??o entre o indiv?duo e o ambiente. Nesse sentido, pretende-se mostrar como as no??es winnicottianas de ser e continuidade de ser, de desenvolvimento da rela??o de depend?ncia para a independ?ncia, bem como a diferencia??o dos diversos tipos de integra??o dos indiv?duos, podem n?o s? explicar comportamentos agressivos no ambiente escolar como tamb?m oferecer possibilidades de reflex?o e de a??es de cuidado e preven??o do comportamento antissocial com enfoque nas principais atitudes desta problem?tica.

This matter was investigated within an interpretation and approach qualitative view of the social phenomena, using the Thematic Analysis technique of drawings and stories which express the relation with the caregiver gotten in sessions of playful interactions between child and researcher in order to understand the child experiences with the social educator. The used theoretical referential is by D. W. Winnicott who associates the social trend to a failure of environment in child holding. The subjects expressed the need of a firm and protective environment and they look for this in NASPM educators. Moreover, they show as solitude and vulnerability take part their lives due to the lack of emotional holding on family that favors the involvement with violent groups. But, it is worth pointing out that the children value the Nucleus environment when has offered them a safe holding which can be positive the established linking with it. Such conclusion points out to the possibility, recognized theoretically, that exists from these children to resume the way of healthy development / O estudo objetiva compreender como as crian?as que apresentam comportamentos expressivos de tend?ncia anti-social no N?cleo de A??o Social da Praia do Meio em Natal - RN, ligado ?

Investigou-se esta quest?o dentro de uma vis?o qualitativa de abordagem e interpreta??o dos fen?menos sociais, utilizando a t?cnica da An?lise Tem?tica dos desenhos e est?rias que expressam a rela??o com o cuidador, obtidos em sess?es de intera??o l?dica entre crian?a e pesquisadora, para a compreens?o das viv?ncias da crian?a com o educador social. O referencial te?rico utilizado ? de D. W. Winnicott, que associa a tend?ncia anti-social ? aus?ncia do holding necess?rio, ou seja a uma falha do ambiente na sustenta??o da crian?a. Os sujeitos expressaram a necessidade de um ambiente firme e acolhedor e buscam isto nos educadores do NASPM. Mostraram, tamb?m, como a solid?o e a vulnerabilidade permeiam suas vidas por causa da falta de sustenta??o emocional na fam?lia, o que favorece o envolvimento com grupos violentos. Mas, vale ressaltar, as crian?as valorizam o ambiente do N?cleo quando lhes oferece um suporte seguro, podendo ser positiva a vincula??o estabelecida com ele. Tal conclus?o aponta que existe a possibilidade reconhecida teoricamente destas crian?as retomarem o caminho do desenvolvimento saud?vel

There is evidence that the level of physical fitness of children and adolescents has declined over time. In this sense studies that verify the secular trend of growth and physical fitness gain importance. Objective: to analyze, through a secular tendency, changes occurred in parameters of physical fitness related to health in schoolchildren from 7 to 12 years of age in the city of Taguatinga- DF, from 1992 to 2015. Materials and Methods: The study addresses With a sample of 2,281students (1,114 males and 1,167 females), from 2001 to 2005 (years 2000) with 774 students (348 boys and 426 girls) and Year of 2015 with 370 students (187 boys and 183 girls), totaling 3,425 students (1649 boys and 1,776 girls). Body mass and height were obtained, which gave rise to the body mass index, tricipital and subscapular skinfolds, with which the percentage of fat was calculated, in addition to agility, flexibility, lower limb strength and sexual maturation. Means, deviations and frequency were analyzed. Normality was verified with Shapiro Wilks and Kolmogorov-Smirnov. In addition to the analysis of variance in case of normality and Kruskal Wallis where there was no normality. The study was approved by the Ethics Committee of the Catholic University of Brasilia under number 1,086,406. Results: Body mass, height, body mass index and fat percentage of boys and girls presented significant differences when we compared the three moments of the study. These variables showed a positive secular trend, mainly when we compare the years 1990 and the year 2015. The results also show that when compared with reference tables for ages and sex the majority are classified in unsatisfactory levels. The variables flexibility and horizontal jump presented a seculartendency negative, demonstrating a worsening of results over time. There was also worsening in the variable agility that presented a positive secular tendency. It was found that the boys in the sample are initiating the process of sexual maturation earlier than the girls. The boys presented better performance in all stages of sexual maturation, except for the variable flexibility, where the girls were better. Conclusions: In a qualitative analysis, the results of the secular trend of both physical growth and motor performance of boys and girls presented worse results when we compared the first moment of the study (1990s) with the present moment (2015). It is suggested a great attention to the objectives of the Physical Education classes at the Public School and a pedagogical supervision to the teachers who teach this discipline. / Introdu????o: As evolu????es tecnol??gicas ocorridas no mundo moderno provocaram mudan??as significativas na forma como crian??as e adolescentes realizam suas divers??es e lazer, levandoos ?? diminui????o do n??vel de atividade f??sica e prejudicando a forma????o de h??bitos saud??veis. H?? evid??ncias que o n??vel de aptid??o f??sica das crian??as e dos adolescentes tem diminu??do com o tempo. Neste sentido estudos que verifiquem a tend??ncia secular do crescimento e da aptid??o f??sica ganham import??ncia. Objetivo: analisar, por meio de tend??ncia secular, modifica????es ocorridas em par??metros da aptid??o f??sica relacionada ?? sa??de em escolares de 07 a 12 anos de idade na cidade de Taguatinga-DF, no per??odo de 1992 a 2015. Materiais e M??todos: O estudo aborda tr??s momentos distintos, de 1992 a 1995 (anos 1990) com uma amostra de 2.281 alunos(1.114 do sexo masculino e 1,167 do sexo feminino), de 2001 a 2005 (anos 2000) com 774 alunos (348 meninos e 426 meninas) e do ano de 2015 com 370 alunos (187 meninos e 183 meninas), totalizando 3.425 alunos (1649 meninos e 1.776 meninas). Foram coletados massa corporal e estatura, que deram origem ao ??ndice de massa corporal, dobras cut??neas tricipital e subescapular, com as quais foi calculado o percentual de gordura, al??m da agilidade, flexibilidade, for??a de membros inferiores e matura????o sexual. Foram analisadas m??dias, desvios e frequ??ncia. A normalidade foi verificada com Shapiro Wilks e Kolmogorov-Smirnov. Al??m da an??lise de vari??ncia em caso de normalidade e Kruskal Wallis onde n??o houve normalidade. O estudo foi aprovado pelo Comit?? de ??tica da Universidade Cat??lica de Bras??lia sob o n??mero 1.086.406. Resultados: A massa corporal, a estatura, o indice de massa corporale o percentual de gordura dos meninos e das meninas apresentaram diferen??as significativas quando comparamos os tr??s momentos do estudo. Estas variaveis apresentaram tend??ncia secular positiva, principalemtne quando comparamos os anos 1990 e o ano de 2015. Os resultados tamb??m mostram que quando comparados com tabelas referenciais para as idades e sexo a maioria est??o classificados em niveis insatisfat??rios. As vari??veis flexibilidade e salto horizontal apresentaram tendencia secular negativa, demonstrando uma piora de resultados ao longo do tempo. Tamb??m houve piora na variavel agilidade que apresentou tendencia secular positiva. Verificou-se que os meninos da amostra est??o iniciando mais cedo o processo de matura????o sexual do que as meninas. Os meninos apresentaram melhor desempenho em todos os est??gios de matura????o sexual, exceto para a variavel flexibilidade, onde as meninas foram melhores. Conclus??es: Numa an??lise qualitativa, os resultados de tendencia secular tanto de crescimento f??sico quanto de desempenho motor dos meninos e meninas apresentaram resultados piores quando comparamos o primeiro momento do estudo (anos 1990) com o momento atual (2015). Sugere-se uma aten????o muito grande aos objetivos das aulas de Educa????o F??sica a Escola P??blica e uma supervis??o pedag??gica aos professores que ministram esta disciplina.

Its importance was demonstrated by the diversity of applications that several studies have already provided to various fields such as biology , economics and Climatology . In physics , the approach of complex systems is creating paradigms that influence markedly the new methods , bringing to Statistical Physics problems macroscopic level no longer restricted to classical studies such as those of thermodynamics . The present work aims to make a comparison and verification of statistical data on clusters of profiles Sonic ( DT ) , Gamma Ray ( GR ) , induction ( ILD ) , neutron ( NPHI ) and density ( RHOB ) to be physical measured quantities during exploratory drilling of fundamental importance to locate , identify and characterize oil reservoirs . Software were used : Statistica , Matlab R2006a , Origin 6.1 and Fortran for comparison and verification of the data profiles of oil wells ceded the field Namorado School by ANP ( National Petroleum Agency ) . It was possible to demonstrate the importance of the DFA method and that it proved quite satisfactory in that work, coming to the conclusion that the data H ( Hurst exponent ) produce spatial data with greater congestion . Therefore , we find that it is possible to find spatial pattern using the Hurst coefficient . The profiles of 56 wells have confirmed the existence of spatial patterns of Hurst exponents , ie parameter B. The profile does not directly assessed catalogs verification of geological lithology , but reveals a non-random spatial distribution / O estudo dos sistemas complexos tornou-se uma ?rea prestigiada da ci?ncia, apesar de ser relativamente jovem. Sua import?ncia foi comprovada pela diversidade de aplica??es que v?rios estudos j? proporcionaram para campos diversos como os da Biologia, Economia e Climatologia. Na F?sica, a abordagem dos sistemas complexos vem criando paradigmas que influenciam de forma marcante os novos m?todos, trazendo para a F?sica Estat?stica problemas de n?vel macrosc?pico n?o mais restritos a estudos cl?ssicos como os da Termodin?mica. O presente trabalho tem como objetivo fazer uma compara??o e verifica??o dos aglomerados estat?sticos de dados relativos aos perfis de S?nico (DT), Raio Gama (GR), Indu??o (ILD), Neutr?nico (NPHI) e Densidade (RHOB) por serem grandezas f?sicas medidas durante a perfura??o de po?os explorat?rios de fundamental import?ncia para localizar, identificar e caracterizar reservat?rios de petr?leo. Foram utilizados os softwares: Statistica, Matlab R2006a, Origin 6.1 e Fortran para a compara??o e verifica??o dos dados dos perfis de po?os de petr?leo da Escola Campo Namorado cedidos pela ANP (Ag?ncia nacional de petr?leo). Foi poss?vel evidenciar a import?ncia do m?todo DFA e que o mesmo mostrou-se bastante satisfat?rio no referido trabalho, chegando-se a conclus?o que os dados do H (expoente de Hurst) produzem dados espaciais com uma maior aglomera??o. Portanto, constatamos que ? poss?vel encontrar padr?o espacial usando o coeficiente de Hurst. Os perfis dos 56 po?os comprovaram a exist?ncia de padr?es espaciais dos expoentes de Hurst, ou seja, par?metro B. O perfil avaliado n?o cataloga diretamente a verifica??o da litologia geol?gica, mas revela a exist?ncia de uma distribui??o espacial n?o aleat?ria / 2024-12-31
