Foram estudadas, neste trabalho, interacões por complexos de transferência de carga, através de medidas gravimétricas do grau de inchamento de géis de poli(isopreno) reticulado,contendo grupos aceptores de carga, em presença de grupos doadores de carga, de pequeno peso molecular, dissolvidos em tolueno. Para este fim, poli(isopreno) sintético proveniente da COPERBO - Companhia Pernambucana de Borracha Sintética, após purificação em clorofórmio, foi caracterizado por espectroscopia no infra-vermelho. O seu peso molecular médio foi determinado por viscosimetria em tolueno e o valor de Mv obtido foi 8,25 x 105. Através de epoxidação da dupla ligacão e hidrólise ácida do respectivo anel oxirano, foram introduzidos no poli(isopreno), previamente purificado, grupos aceptores de carga do tipo cloranil e ácido 3,5-dinitro-benzóico, e grupos doadores de carga do tipo carbazola. Obteve-se, desta forma, copolímeros aceptores do tipo poli (isopreno - co-cloranil) e poli(isopreno-co-(3,5-dinitro-benzoato)) e copolímero doador do tipo poli(isopreno- co-carbazola). A quantidade de cada espécie introduzida foi determinada por espectroscopia no ultra violeta. Poli(isopreno) e os copolímeros contendo grupos doadores ou aceptores foram reticulados em solução utilizando 4,4'-(4,4'-difenilmetileno)-bis- 1,2,4-triazolina-3,5-diona (BPMTD). Os filmes reticulados, após retirada a fase sol, e secos à vácuo, foram submetidos a inchamento em tolueno puro e em solução de tolueno contendo grupos aceptores ou doadores de carga, nas proporções 10:1, 1:1 e 1:10 (polímero: grupo doador ou polímero: grupo aceptor de carga), a 25, 30, 35 e 40ºC. Das medidas gravimétricas do grau de inchamento, foi verificado a formação de complexos por transferência de carga entre os copolímeros aceptores e carbazola. Foi verificado ainda que copolímeros contendo grupos aceptores do tipo cloranil possuem maior tendência a formar complexos por transferência de carga do que copolímeros aceptores contendo grupos 3,5-dinitro-benzoíla.

O presente estudo investigou o nível de burnout, em cada uma de suas três dimensões, dos educadores (professores e educadores assistentes), que trabalham em escolas de Educação Infantil do Município de Porto Alegre, sendo duas da rede privada, duas da rede pública e uma escola comunitária. Também verificou os fatores reconhecidos como estressores no trabalho desses profissionais e a representação de estresse que fazem de seu trabalho. Os resultados evidenciaram níveis altos para a dimensão "Exaustão Emocional", baixo para "Despersonalização" e baixo para a dimensão "Reduzida Realização Profissional" independentemente do tipo de escola ou função exercida pelos sujeitos da amostra. Das variáveis demográficas, apenas o tempo disponível para o lazer apresentou associação significativa com a dimensão "Exaustão Emocional", indicando que os educadores que não dispunham de tempo para o lazer encontravam-se mais cansados emocionalmente. Com relação às variáveis ocupácionais, somente o número de alunos influenciou significativamente os níveis de burnout na dimensão "Exaustão Emocional" Os educadores avaliados consideram como baixo seu estresse no trabalho e relacionam o relacionamento com os familiares dos alunos como principal fator estressor. Os fatores estressores, organizados por ordem de importância , ao serem avaliados por tipo de escola , não apresentaram associação significativa entre as variáveis em estudo. Os fatores demanda mental e frustação causaram impacto na dimensão "Exaustão Emacional". Constatou-se, portanto, que as características do trabalho e a exigência das relações interpessoais são fatores desencadeantes da síndrome no grupo amostrado segundo os participantes da pesquisa.

Problemas de saúde pública causados pelo consumo de carnes envolvem diversos países e obrigam a cadeia agroalimentar a repensar o modo de produção e os sistemas de garantia de qualidade. Devido a este fato, esta pesquisa teve como objetivo estudar a rastreabilidade na cadeia avícola, tendo como foco o consumidor. Para isso foi realizado um survey, no qual foram realizadas entrevistas com 393 consumidores da cidade de Porto Alegre. Os questionários foram aplicados no período de abril a julho de 2004 em supermercados de pequeno, médio e grande porte, além do mercado público da cidade. Os atributos sanitários que o consumidor considera importantes para se rastrear na carne de frango são: Influenza Aviária (Gripe do Frango), Salmonela, Hormônios, Controle do Índice de Absorção de Água e Resíduos de Antimicrobianos. Além disso, os entrevistados consideram que as seguintes informações devam constar na embalagem da carne de frango: Data de Validade, o número do SIF, Certificado de Qualidade, Advertência quanto a Riscos de Toxinfecção Alimentar, Preço, Data de Abate e Origem/Procedência. São exploradas na pesquisa as correlações de diversas variáveis com o nível de escolaridade, renda e faixa etária. Com base nestes dados e utilizando a análise de filière, buscou-se propor maneiras de se atingir na rastreabilidade os pontos cruciais indicados pelos consumidores. Apesar da cadeia avícola ser bem organizada, foi evidenciada por esta pesquisa a necessidade de melhorar a circulação da informação na cadeia; para isso, sugere-se um sistema integrado de informação. Finalmente, foi proposto um modelo de rastreabilidade que contempla toda a cadeia avícola, incluindo todos os elos, desde o consumidor até o matrizeiro, indicando-se possíveis fatores que podem dificultar a construção do mesmo.

Este estudo objetiva analisar os processos de recuperação judicial iniciados, desde a vigência da Lei de Recuperação de Empresas (fevereiro de 2005) até 31/06/2011 nas varas empresarias da comarca da capital do Tribunal de Justiça do Estado do Rio de Janeiro. Além da aferição do tempo médio de cada uma das etapas previstas na Lei de Recuperação de Empresas (deferimento do processamento da recuperação judicial, concessão da recuperação judicial e encerramento do processo após cumprimento de todas as obrigações previstas no plano que se vencerem até dois anos depois da concessão da recuperação judicial), busco também verificar se, de fato, alguma sociedade requerente conseguiu se recuperar. Para tanto, considerarei recuperada a sociedade que, após o encerramento do processo, estiver cumprindo plenamente o seu plano de recuperação, sem que tenha havido qualquer requerimento posterior de falência. Considerando que a Lei de Recuperação de Empresas já está no seu sétimo ano de vigência, bem como o fato de o legislador ter idealizado o processo para que dure no máximo 3 anos, entendo não haver óbices à adoção do conceito supra, tendo em vista que já haver tempo suficiente para o início e encerramento desse tipo de processo. Diante disso, o presente estudo observou que o tempo médio para cumprimento das etapas ultrapassa o limite do razoável, bem como que nenhuma sociedade conseguiu se recuperar até o desfecho da pesquisa, havendo casos, inclusive, de convolação da recuperação judicial em falência.

A headspace solid-phase microextraction (HS-SPME) procedure based on five commercialised fibres (85 μm polyacrylate – PA, 100 μm polydimethylsiloxane – PDMS, 65 μm polydimethylsiloxane/divinylbenzene – PDMS/DVB, 70 μm carbowax/divinylbenzene – CW/DVB and 85 μm carboxen/polydimethylsiloxane – CAR/PDMS) is presented for the characterization of the volatile metabolite profile of four selected Madeira island fruit species, lemon (Citrus limon), kiwi (Actinidia deliciosa), papaya (Carica papaya L.) and Chickasaw plum (Prunus angustifolia). The isolation of metabolites was followed by thermal desorption gas chromatography–quadrupole mass spectrometry (GC–qMS) methodology. The performance of the target fibres was evaluated and compared. The SPME fibre coated with CW/DVB afforded the highest extraction efficiency in kiwi and papaya pulps, while in lemon and plum the same was achieved with PMDS/DVB fibre. This procedure allowed for the identification of 80 compounds, 41 in kiwi, 24 in plums, 23 in papaya and 20 in lemon. Considering the best extraction conditions, the most abundant volatiles identified in kiwi were the intense aldehydes and ethyl esters such as (E)-2-hexenal and ethyl butyrate, while in Chicasaw plum predominate 2-hexenal, 2-methyl-4-pentenal, hexanal, (Z)-3-hexenol and cyclohexylene oxide. The major compounds identified in the papaya pulp were benzyl isothiocyanate, linalool oxide, furfural, hydroxypropanone, linalool and acetic acid. Finally, lemon was shown to be the most divergent of the four fruits, being its aroma profile composed almost exclusively by terpens, namely limonene, γ-terpinene, o-cymene and α-terpinolene. Thirty two volatiles were identified for the first time in the fruit or close related species analysed and 14 volatiles are reported as novel volatile metabolites in fruits. This includes 5 new compounds in kiwi (2-cyclohexene-1,4-dione, furyl hydroxymethyl ketone, 4-hydroxydihydro-2(3H)-furanone, 5-acetoxymethyl-2-furaldehyde and ethanedioic acid), 4 in plum (4-hydroxydihydro-2(3H)-furanone, 5-methyl-2-pyrazinylmethanol, cyclohexylene oxide and 1-methylcyclohexene), 4 in papaya (octaethyleneglycol, 1,2-cyclopentanedione, 3-methyl-1,2-cyclopentanedione and 2-furyl methyl ketone) and 2 in lemon (geranyl farnesate and safranal). It is noteworthy that among the 15 volatile metabolites identified in papaya, 3-methyl-1,2-cyclopentanedione was previously described as a novel PPARγ (peroxisome proliferator-activated receptor γ) agonist, having a potential to minimize inflammation.

The aim of this study is to understand the perception of medical students at the Federal University of Rio Grande do Norte (UFRN) about humanization in the context of their medical formation, using a qualitative approach. The focus group and participant observation techniques were used, involving a multidisciplinary team composed of professionals from the areas of anthropology and psychology, as well as professors from the medical course, who studied two groups of nine students in their final year. The data were analyzed using the categorical thematic content analysis technique, from which emerged three categories: student/patient relationship, teaching/learning and student/professor relationship. The first allows us to identify that student-patient contact is an essential experience for adopting a more humanized view of the disease process. The second category shows that unqualified professors in the pedagogic practices inherent to the teaching profession and the theory the practical dichotomy hinder the autonomous and holistic formation of knowledge. Similarly, the lack of practices outside the academic environment and the absence of multiprofessional stimulation interfere in the construction of an integral view of the individual. From the third category, the student/professor relationship, emerge two opposing subcategories (professor model and assymetric relationships), which reflect the importance of the professor`s ethical humanist position, as opposed to an authoritarian attitude, to form the professional attitude of the student. The results point important aspects of the medical formation that may open a discussion about humanization, in the context of new national curricular guidelines

El objetivo en esta tesis consistió en estudiar el proceso de los cambios de los conceptos de profesores de la educación infantil y de los años iníciales de la educación básica referente a la enseñanza de la matemática. La investigación se desenvolvió en la escuela Presidente Kennedy, en la ciudad de Natal, en Rio Grande do Norte, teniendo como participante 05 (cinco) profesores del curso normal superior a través de la educación superior del instituto relacionado. El trabajo asocia el programa a él Programa de Pós-Graduação em Educação da Universidade Federal do Rio Grande do Norte, en la base de pesquisa Formação e Profissionalização Docente coordinada de los doctores Betânia Leite Ramalho e Isauro Beltran Núñez. El referencial teórico-metodológico en quien si apoya el trabajo se inserta en la señal conceptual usada por Giordan y de Vecchi (1996), de Carrillo y Contreras (1994), Ramalho; Núñez y Gauthier (2003), Ponte (1998), Guimarães (1988), Ernest (1989). En esta investigación, los conceptos de los profesores habían sido estudiados en el contexto educativo de la formación del nivel superior, usándola reflexiva crítico práctico como estrategia formativa. Estos conceptos se entienden como estructuras subyacentes al pensamiento del profesor. Dado la naturaleza del objeto del estudio, la información, para las intenciones de esta investigación, habían sido cosechados a través de los instrumentos siguientes: cuestionario, plan de la lección, entrevista diaria y del campo. El cuestionario fue constituido de preguntas abiertas y de las entrevistas de la mitad-structuralized. La organización de los datos permitió a La inferencia de los conceptos, usando la técnica de la triangulación de datos. La investigación divulgó que los conceptos de los profesores, a través del proceso formativo, se habían desarrollado de una plataforma para otra, yéndose puesto que los modelos didácticos tradicionales para otros modelos dirigidos a una tendencia didáctica de espontaneísta/investigativa. La reflexión crítica era considerada como elemento catalítico de los cambios de los conceptos de los profesores en la educación de las matemáticas, sin embargo déjenos verifican que estos cambios son difíciles de ocurrir para la naturaleza compleja de estos conceptos. Como facilitadores de los factores de estos cambios, encontramos y el investigativo el trabajo, la dinámica y la naturaleza de las actividades se convirtió en el colaborativo de proceso formativo, entre otros. Como obstáculos a los cambios, identificamos el contexto del trabajo de los profesores, de la cultura de los individualistas prácticos de sus profesores de los colegas, del concepto linear, estático y de los mecánicos de los procesos para enseñar, el conocimiento profesional construído durante la formación inicial, alineación con los modelos didácticos de sus viejos profesores, entre otros

This dissertation aims at analyzing some relations established between teachers‟ formative proposal for docent knowledge and pedagogical practices in the Special Program of Professional Formation to Basic Education (Proformação in Portuguese) with the objective of investigating how teachers evaluate knowledge acquired during their course formation to identify its improvement in their pedagogical practice. This is a Pedagogical Program of the State University of Rio Grande do Norte chosen to be analyzed. The objective is to investigate how teachers, Proformação/Pedagogy course students evaluate privileged knowledge in that university formation and how the relation between this knowledge and their pedagogical practice are experienced in classroom as teachers, defining in which way knowledge constructed and reconstructed during the course contributes for an improvement of their pedagogical practices. We have interviewed fourteen Proformação/Pedagogy last-term teachers, emphasizing the analysis of their point of view as social actors related to docent university formation in service. The principles for this investigation comprehend a qualitative approach, in a case study modality, with an exploratory tendency, presented in the introductory section and along four chapters. The research is theoretically guided by Andoino (1998), Bardin (2009); Laville e Dione (1999); Bogdan and Biklen (1994), Hernandez Sampieri, Hernandez Collado and Baptista Lúcio (2006), among others. We justify this thematic choice, considering docent formation and its interface with an improvement for students‟ leaning, taking into account the strict relations between those elements. We have discussed on docent formative paradigms, based on a multireferential perspective, whose main authors that developed research in this area are: Gómez (1998), Sacristán e Gómez (1998), Tardif (2002), Altet (2001) Paquay e Wagner (2001), Garcia (1999), Baldi (2008), La Torre e Barrios (2002). We interviewed fourteen teachers, all of them in the last term of the Program. In the second chapter, we justify the choice of the subject, approaching docent formation and its relation with basic teaching. We understand that there is a strong relation between those aspects. In the third chapter, we discuss on some docent formative paradigms, among them, Gomes (1998), Sacristán and Gomez (1998), Tardig (2002), Altet (2001) Paquay and Wagner (2001), Garcia (1999), Baldi (2008), La Torre and Barrios (2002). We introduce the Pedagogical Program structure and specify which formative paradigms characterize it and identifying that one of the most prominent paradigm is a practical perspective with emphasis on reflexivity about the practice based on the premise that docent formation is be based on from learning to practice theory. We present an data analysis obtained from thematic categorization extracted subjects‟ discourses and, at the end, we discuss on evaluation of the teachers involved in the research related to the course contributions to provide an improvement for pedagogical practices developed by them inside their classrooms. We consider, thus, that teachers evaluate the Program as a guideline for (re)construction of diversified knowledge, which, in turn, provides the development of abilities to analyze classroom situations based on pedagogical theories and to develop investigative practice based on everyday experience. The results point out that some implications are relevant, among them: the thematic-choice, discussed previously, needs other kinds of investigations. The relation between theory and practice proposed in formation programs requires more systematic studies considering others aspects that characterize teaching process, and mainly, to provide investigative proposals of and about such practices

The present work is grounded basically on the use of the Basic Tools for the Statistic Process Control SPC, with the intent to detect non-conformities on a given productive process. It consists on a case study accomplished at a Hemocenter in Natal (Rio Grande do Norte). In this study it is shown that, the Statistic Process Control Technique, which was used as a tool, is useful to identify on-conformities on the volume of hemocomponents. The gathering of the used data was performed by means of document analysis, direct observations and database queries. The results achieved from the study show that the analyzed products, even though when they have presented, in some cases, points out of control, they satisfied the ANVISA standards. Finally, suggestions for further improvement of the final product and guidance for future employment of CEP, also extended to other lines of production, are presented

This Master Thesis presents a case study on the use of Statistical Process Control (SPC) at the Núcleo de Pesquisas em Alimentos e Medicamentos (NUPLAM). The SPC basic tools have been applied in the process of the tuberculostáticos drugs encapsulation, primarily concerning the objective to choose, between two speeds, which one is the best one to perform the tuberculostatics encapsulation. Later on, with the company effectively operating, the SPC was applied intending to know the variability of the process and, through the tracking of the process itself, to arrive at an estimated limit for the control of future lots of tuberculostatics of equal dosage. As special causes were detected acting in the process, a cause-and-effect diagram was built in order to try to discover, in each factor that composes the productive process, the possible causes of variation of the capsules average weight. The hypotheses raised will be able to serve as a base for deepened the study to eliminate or reduce these interferences in the process. Also a study on the capacity of the process to attend the specifications was carried out, and this study has shown the process´s inaptitude to take care of them. However, on the side of NUPLAM exists a real yearning to implant the SPC and consequently to improve the existing quality already present on its medicines

This master´s thesis presents a reliability study conducted among onshore oil fields in the Potiguar Basin (RN/CE) of Petrobras company, Brazil. The main study objective was to build a regression model to predict the risk of failures that impede production wells to function properly using the information of explanatory variables related to wells such as the elevation method, the amount of water produced in the well (BSW), the ratio gas-oil (RGO), the depth of the production bomb, the operational unit of the oil field, among others. The study was based on a retrospective sample of 603 oil columns from all that were functioning between 2000 and 2006. Statistical hypothesis tests under a Weibull regression model fitted to the failure data allowed the selection of some significant predictors in the set considered to explain the first failure time in the wells

The present study presents an investigation concerning the factors that, in the perception of the extension of Emater/RN they affect the competitiveness of the productive chain of the coconut in Rio Grande do Norte. For so much it is used of a theory structured starting from the several aspects that delineate the competitiveness and your respective factors, besides the aspects that compose the productive chain of the coconut in Rio Grande do Norte. The research was accomplished at the mesorregião Leste Potiguar of Rio Grande do Norte, territory of larger index of coconut production in the state. The used methodological approach was the one of descriptive exploratory research together to the conduction of a rising type Survey. The field research obtained 35 valid questionnaires, whose interviewees were the extension of Emater/RN in performance in the municipal districts that compose the mesorregião Leste Potiguar of Rio Grande do Norte. The results allow to end that in the perception of the extension, the level of competitiveness of the productive chain of the coconut in Rio Grande do Norte is still low, presenting as larger fetter the low price of the coconut and the high costs of the productive process, being recommended a larger support to the producing of coconut in relation to technical attendance, incentive actions to the quality, understanding with relationship to the benefits of the creation of partnerships, associations and cooperatives, as well as the promotion of the knowledge of the productive chain of the coconut in Rio Grande do Norte for subsequent ends of all the agents' of that chain training with relationship to the importance of the development of competitive advantages

This work aims to understand the teaching of English at the Federal Institute of considering the recommendations of official and technical documents for the integrated secondary school and the perspective of the English teachers settled in one of the campuses of the Institute. It is also an objective of this research to infer as to what extent the perspective of teachers is articulated to the documental recommendations. For this purpose, several official and technical documents (LÜDKE; ANDRÉ, 1986), such as the PCNEMs (BRAZIL, 2000), the OCNEMs (BRAZIL, 2006) and the Political-Pedagogical Project of the Institute (IFRN, in press) were gathered, and a questionnaire was submitted to six teachers of English from one of the campuses of the institution. The theoretical references of the research include, among others, Bakhtin (1997; 1999), Widdowson (1991), Almeida Filho (2011; 2004), Celani (1988; 2009), Hutchinson and Waters (1987) and Dudley-Evans and St. John (1998). The results show that the teaching of English according to the documents predicts the instrumental use of the foreign language, but suggests the development of competences and skills as contextualized social practices, aimed at the education of the student as a professional-citizen. The perspective of teachers, in turn, points to a concern that the teaching of English serves as a tool for improving student life through the instrumental use of language as a means of accessing information and professional training. This finding reveals that the articulation between the documental recommendations and perspective of teachers does not go beyond what refers to the instrumental language teaching, since teachers do not show, when reporting their practices, the teaching of language as social practice, as mentioned in the legal texts
