We used 2,970 day-old chicks, male and female, sexed, three cultivars of commercial broilers (Cobb 500, Hubbard Flex and Ross 308). We used three nutritional programs with different levels of amino acids. The broilers were distributed in a completely randomized design in factorial design 3x3x2 (genotype x diet x sex) with five replications and 33 birds / plot. The characteristics of feed conversion (FC) , average daily weight gain (ADG) and feed intake average individual (CR) body weight at 35 (PC35) , 42 (PC42) and 49 (PC49) days of age . Two birds per replicate were slaughtered at 35, 42 and 49 days of age to evaluate carcass traits: body weight at slaughter weight and carcass yield, weight and yield of cuts (breast, legs and wings). It was found in the period 1-35 days genotype x sex interaction for ADG and PC35. In the period 1-42 days of age, there were no differences among genotypes for PC42, CR, DWG or CA. There was significant interaction sex x genotype for breast weight, and between broilers, Cobb 500 had higher breast weight, did not differ from Ross 308 males, who in turn did not differ from males Hubbard. Finally, in the period 1-49 days of age, there was no difference between genotypes CR, DWG or PC49. In general, the performance of broilers Cobb 500, Hubbard Flex and Ross 308 were not very different, and these differences were more present in carcass characteristics. The basal diet showed, in general, better results than diets with more or less 10 % of amino acids, which shows the good nutritional adequacy of the same. The males showed themselves superior, overall, to the performance characteristics and carcass, compared to females.

We investigated the prevalence of women in conversions by analyzing the main reasons why they decided to seek another religious affiliation, as well as the reasons for men's adherence to Protestant groups. We recognized that women's motivations were related to marital and/or family issues, while for men they referred to personal matters. We analyzed the demonization of Candombl? by evangelical groups, especially the Igreja Universal do Reino de Deus as well as the speech of practitioner of Candombl? before the disqualification practices of Candombl? and the numerical growth of conversions practitioner of Candombl? to the Protestant denominations. The applicant was disqualified and demonization of african-Brazilian religious practices. Observe how new religious affiliation and religious transit influence on family relationships, analyzing how conflict and family tensions began to be administered by the newly converted. It was recurrent the disqualification and demonization of african-Brazilian religious practices.

Conversion is the realization of the human being, a meeting with the Supreme Good and Truth, which involves an ascent of the soul and intelligence to God, walking on the path of renunciation to the sin and the search of holiness. In this way, Plotinus, a pagan philosopher, presents it as a epistroph?; in other wise, Augustine identifies it to Christian met?noia. Both approaches make use of a metaphysical structure that serves as the support for mystic, where it is possible to estabilish a rapprochement between the two systems. Thus, the religious philosophy of Plotinus will greatly influence the thinking of Augustine in a first step of his life, but he (Augustine) progressively overcomes at the same time in wich he enters, more and more, into the knolodge of the Sacred Scriptures mainly by reading St. Paul. / O processo de convers?o a Deus, pela via racional e m?stica, ao ser abordado pela ?tica da f? e da raz?o humana, ? objeto de estudo tanto da filosofia, quanto da teologia. A convers?o ? a realiza??o plena do ser humano, um encontro com a Verdade e o Sumo Bem, que implica uma ascens?o da alma e da intelig?ncia at? Deus, percorrendo a via da ren?ncia ao pecado e a busca da santidade. Nesse percurso, Plotino, um fil?sofo pag?o, a apresenta como sendo uma epistroph?; por sua vez, Santo Agostinho a identifica com a met?noia crist?. Ambas abordagens utilizam-se de uma estrutura metaf?sica que serve de suporte para a m?stica, onde ? poss?vel determinar uma aproxima??o entre os dois sistemas. Assim, a filosofia religiosa de Plotino vai influenciar sobremaneira o pensamento de Agostinho numa primeira etapa de sua vida, mas ele (Agostinho) a ultrapassa progressivamente, na medida em que adentra, cada vez mais, no conhecimento das Escrituras Sagradas, m?xime, a leitura de S?o Paulo.

Especially This work encompasses the analysis of the cross-layer effect caused by all-optical wavelength converters in the video signal. For this purpose, it was evaluated the packet error rate degradationcaused by physical layer parameters. Such analysis was made for a video signal propagation through the KyaTera Network, followed by an all optical wavelength conversion. The experimental results allowed concluding that converted signals separated by up to 1.5 THz from the original signal may experience 2.1-dB penalty. This fact indicates that for each wavelength conversion the signal propagation range will be reduced in 10 km (Considering an attenuation of 0.2 dB/km in the transmission fibers). It was also verified that the presence of the all-optical wavelength converter in the network implies a 16-dB power penalty. For this reason the wavelength conversion is a viable option for cases where the propagation distance for the unconverted signal is larger than 80 km. Results indicate the existence of a strong relation between the packet error rate and the degradation of the optical signal-noise ratio caused by the mentioned converter. It was not found any reference in the literature of any work with this type of characterization. Additionally, experiments to emulate the degradation of the video signals transmitted through links with a cascade of optical amplifiers were also performed. The results indicate that the packet error rate is related not only with optical signal-noise ratio, but also with the received signal power. / Este trabalho teve como objetivo avaliar experimentalmente como impedimentos f?sicos de redes ?pticas afetam o desempenho de aplica??es IP. Em especial, esse trabalho compreendeu a an?lise do efeito de cross-layer causado por conversores de comprimento de onda totalmente ?pticos em sinais de v?deo. Para isso avaliou-se a degrada??o da taxa de erro de pacotes em fun??o de par?metros da camada f?sica. Essa an?lise foi feita para uma propaga??o do sinal de v?deo pela Rede KyaTera, seguida de uma convers?o de comprimentos de onda totalmente ?ptica. Os resultados experimentais permitiram concluir que sinais convertidos, separados do sinal original por at? 1,5 THz, sofrem uma penalidade m?dia de pot?ncia de 2,1 dB. Este fato indica que para cada convers?o que o sinal sofrer o seu alcance ser? reduzido em aproximadamente 10 km (admitindo-se uma atenua??o de 0,2 dB/km nas fibras da rede). Concluiu-se tamb?m que a presen?a do conversor de comprimentos de onda na rede implica em uma penalidade de 16 dB. Este fato torna a convers?o de comprimentos de onda uma op??o vi?vel para os casos nos quais o sinal n?o convertido tenha de ser propagado por uma dist?ncia superior a 80 km. Os resultados obtidos indicam que existe uma forte correla??o entre a taxa de erro de pacotes da transmiss?o do sinal de v?deo e a degrada??o da raz?o sinal-ru?do ?ptica imposta pelo referido conversor. N?o foi encontrada nenhuma refer?ncia na literatura de qualquer trabalho que fizesse uma caracteriza??o desta maneira. Adicionalmente tamb?m foram realizados experimentos para emular a degrada??o de sinais de v?deo transmitidos por enlaces com uma cascata de amplificadores ?pticos. Os resultados deste experimento indicam que a taxa de erro de pacotes est? relacionada n?o apenas com a raz?o sinal-ru?do ?ptica, mas tamb?m com a pot?ncia do sinal no receptor.

The research is justified, because Brazil shelter the fourth greater arrested population arrested of the world, with projections indicating that it can turn the greatest in 2034. Besides, this study about religious conversion of prisoners to the Social Sciences is too important, because is a theme little developed in Brazil and deserves attention, one time that as the arrested people as the evangelicals are in expansion in our country. Starting from the precedent observations, we guide ourselves by the following problematic of research: the religious practice in Alca?uz presents a mere instrumental perspective, where the actions of prisoners converted was on purpose oriented to conquest material or symbolic privileges; or purely religious, where seek a moral renovation? To develop the work, the scientific methodology adopted was exploratory and explanatory, using the Goffman?s theory about total institutions and presentation of self, and Blumer?s doctrine relating to Symbolic Interacionism and the Story life method, besides considerations about evangelical religion. Having this theoretical basis, was accomplished the Field research, when were made interviews and applied questionnaires to 11 Jailer Agents, 31 prisoners, Director and Vice-Dictor (in November, 2011), the coordinator of social projects of the prison and the coordinator of evangelization at the prisons in Rio Grande do Norte. As results, it was seeing in Alca?uz that the prisoners can be separated in two groups: the one of Pavilions and other one of the Medical Section. The Pavilions are branded for managerial and structural problems, where are found idle prisoners in collective cells and with a historical of escaping attempts, mutinies and murders. The Medical Section has some individual cells or destined for two people, besides few collective also, and the prisoners work and have a more disciplined behavior, there isn t escapes or rebellions and that, for these reasons end for have more confidence from the Administration. About the presence of evangelical prisoners, most are at Medical Section, where exist a specific place to the cults (what doesn t at Pavilions). At the end, the conclusion is that the prisoner that says himself evangelical in Alca?uz, although can be seeing with distrust about your real conversion, he gets win a trust vote and until the opposite being demonstrated in other words, that he is not hiding himself behind the bible to divert the vigilance of Direction and practice disciplinary faults without make any suspicions, is treated with more respect and has more opportunities live at Medical Section; have work, that most of times is paid and guarantee the homologation of your payment of penalty with work, besides other benefits, diminishing his time in jail / O tema da pesquisa encontra-se inserido em um campo de interse??o entre a Sociologia da Religi?o e a Sociologia da Viol?ncia, tendo como objetivo geral estudar o significado sociol?gico da convers?o de presos que vivem no maior estabelecimento prisional (Penitenci?ria de Alca?uz) do Rio Grande do Norte ?s igrejas evang?licas. A pesquisa se justifica, pois o Brasil abriga a quarta maior popula??o carcer?ria do mundo, com proje??es indicando que ela poder? se tornar? a maior do mundo em 2034. Al?m disso, esse estudo sobre convers?o religiosa de presos para as Ci?ncias Sociais ? muito relevante, pois ? um tema pouco desenvolvido no Brasil e merece aten??o, uma vez que tanto a massa carcer?ria quanto os evang?licos est?o em expans?o em nosso pa?s. A partir das observa??es precedentes, orientamo-nos pela seguinte problem?tica de pesquisa: a pr?tica religiosa em Alca?uz apresenta uma perspectiva meramente instrumental, na qual as a??es dos presos convertidos estariam propositalmente orientadas para conquistar privil?gios materiais ou simb?licos; ou puramente religiosa, onde se busca uma renova??o moral? Para desenvolver o trabalho, a metodologia empregada foi explorat?ria-explicativa, utilizando-se a teoria de Goffman sobre institui??es totais e a cerca da representa??o do eu, e a doutrina de Blumer relativa ao Interacionismo Simb?lico e o m?todo da Hist?ria de Vida, al?m de considera??es sobre a religi?o evang?lica. De posse dessa base te?rica, foi realizada a pesquisa de campo, na qual foram feitas entrevistas e aplicados question?rios a 11 Agentes Penitenci?rios, 31 presos, Diretor e Vice Diretor (em novembro de 2011), o coordenador dos projetos sociais do Pres?dio e o coordenador de evangeliza??o nos pres?dios do Rio Grande do Norte. Como resultado, verifica-se que em Alca?uz os presos podem ser separados em dois grupos: o dos Pavilh?es e os do Setor M?dico. Os Pavilh?es s?o marcados por problemas estruturais e gerenciais, onde se encontram presos ociosos em celas coletivas e com um hist?rico de tentativas de fugas, motins e assassinatos. O Setor M?dico tem algumas celas individuas ou para duas pessoas, al?m de coletivas tamb?m, e os presos trabalham e s?o mais comportados, n?o h? fugas ou rebeli?es e que, por esses motivos acabam por ter maior confian?a por parte da Administra??o. Quanto ? presen?a de presos evang?licos, a maioria est? no Setor M?dico, onde h? um local espec?fico para os cultos (o que n?o existe nos Pavilh?es). Por fim, concluise que o preso que se diz evang?lico em Alca?uz, embora seja visto com desconfian?a quanto a sua real convers?o, acaba por ganhar um voto de confian?a e at? que se prove o contr?rio ou seja, que n?o est? se escondendo atr?s da b?blia para desviar a vigil?ncia da Dire??o e praticar faltas disciplinares sem levantar maiores suspeitas, ? tratado com mais respeito e tem mais oportunidades morar no Setor M?dico; ter trabalho, que na maioria das vezes ? remunerado e garantir o reconhecimento de sua remi??o de pena, al?m de outros benef?cios, encurtando assim o seu tempo de pris?o

Constantly, they have to look for the improvement in the quality of their services. To improve this scene of competition the Strategic Planning becomes a referencial to the organizations trace their ways in projected and organized way, optimizing the use of human and financial resources. However for its elaboration it is necessary to use a set of information, restricted, for development of an adequate product for the Institution. In this direction, the area of the Information Science, specifically the Knowledge Management, can contribute with the process of elaboration of the Strategic Planning. Thus, the objective of this work is verify the application of these techniques to the process of elaboration of a Strategic Planning. To prove the viability of this application, an analysis of a developed Strategic Planning will be carried through, for an Institution of Superior Education, without the formal use of the techniques of Knowledge Management. / Com as constantes mudan?as do mundo globalizado e o acirramento da concorr?ncia, as incertezas do futuro s?o cada vez maiores para qualquer organiza??o. N?o menos diferente ? a situa??o das Institui??es de Ensino Superior do Brasil. Dessa forma, as Institui??es t?m que buscar constantemente a melhoria na qualidade dos servi?os prestados para manter e conquistar novos alunos. Para melhorar esse cen?rio de concorr?ncia, o Planejamento Estrat?gico torna-se um referencial para as organiza??es tra?arem seus caminhos de maneira projetada e organizada, otimizando a utiliza??o dos recursos humanos e financeiros. Por?m, para a sua elabora??o, ? necess?rio utilizar um conjunto de informa??es, cada vez mais restritas, para o desenvolvimento adequado da Institui??o. Nesse sentido, a ?rea de Ci?ncia da Informa??o, especificamente a Gest?o do Conhecimento, com sua t?cnica de intera??o entre os modos de convers?o do conhecimento apoiada pelo tesauro funcional, pode contribuir com o processo de elabora??o do Planejamento Estrat?gico. Assim, este trabalho visa verificar a aplica??o dessa t?cnica, tendo como suporte o tesauro funcional no processo de elabora??o de um Planejamento Estrat?gico. Para comprovar a viabilidade dessa aplica??o, foi realizada uma an?lise de um Planejamento Estrat?gico desenvolvido por uma Institui??o de Ensino Superior, sem a utiliza??o desses conceitos.
