However, with the fragmentation of this environment and consequent loss of the native area, owed due mainly to the urban growth, this species takes serious extinction risk, becoming indispensable studies that seek auxiliary in the understanding of your ecology, as the action of parasitoids phorids (Diptera: Phoridae). This work had as main objective to study possible associations of these flies with A. robusta. During the period between June 2009 and October 2010 two restinga environment were studied in the city of Rio de Janeiro: Parque Marapendi and restinga da Marambaia. In each environment they two areas were chosen (with differentiated vegetable composition), an open and more degraded, and another closed, more preserved. In each area nine colonies of A. robusta were chosen, totaling 36 colonies in the four areas of the two environments. Every day of data collection consisted of six hours of observation, divided in eight times of 45 minutes. These observations were made in trails and entrance of the nests, in a consecutive way, always beginning for the entrance nests. In the first ones 15 of each time were to verify the traffic of ants and the 30 remaining minutes, for capture of the phorids that attacked A. robusta. Environmental variables (temperature and humidity) were logged, as well as the attack place (trails and nests entrances). Seventy three phorid flies of two species were collected: Neodohrniphora sp. (46 individuals) and Myrmosicarius sp. (27 individuals). The first one was confirmed as a new species and it was more frequent in more closed restinga areas, while the second, with open areas. The two species attack in trails and entrance of the nests. The number of individuals of Myrmosicarius sp. was influenced negatively with the temperature and positively with the relative humidity of the air. In the case of Neodohrniphora sp. nov., all the regressions relating the number of individuals captured with the studied variables were not significant. The phorid species appear to be linked to specific areas of restinga, in which temperature and humidity are factors limiting the performance of parasitoids Myrmosicarius sp., but do not regulate the behavior of parasitoid Neodohrniphora sp nov. / A formiga cortadeira Atta robusta Borgmeier, 1939 (Hymenoptera: Formicidae) ? uma esp?cie end?mica de ambientes de restinga existentes entre os Estados do Rio de Janeiro e Esp?rito Santo. Por?m, com a fragmenta??o deste ambiente e conseq?ente perda da ?rea nativa, devido principalmente ao crescimento urbano, esta esp?cie corre s?rio risco de extin??o, tornando-se imprescind?veis estudos que visem auxiliar na compreens?o de sua ecologia, como a a??o de for?deos parasit?ides (Diptera: Phoridae). Este estudo teve como objetivo principal estudar poss?veis associa??es destas moscas com A. robusta. Durante o per?odo entre junho de 2009 e outubro de 2010 foram estudados dois ambientes de restinga na cidade do Rio de Janeiro: Parque Marapendi e restinga da Marambaia. Em cada um destes ambientes foram escolhidas duas ?reas (com composi??o vegetal diferenciada), uma aberta e mais degradada, e outra fechada, mais preservada. Em cada ?rea foram escolhidas nove col?nias de A. robusta, totalizando 36 col?nias nas quatro ?reas dos dois ambientes. Cada dia de coleta de dados constou de seis horas de observa??o, divididas em oito tempos de 45 minutos. Estas observa??es foram feitas em trilhas e em olheiros, de forma consecutiva, sempre se iniciando pelos olheiros. Os 15 primeiros minutos de cada tempo foram para verificar o tr?fego de formigas e os 30 minutos restantes, para captura de for?deos que atacavam A. robusta. Vari?veis ambientais (temperatura e umidade) foram anotadas, bem como o local de ataque (trilha e olheiro). Foram coletados 73 for?deos de duas esp?cies: Neodohrniphora sp. nov. (46 indiv?duos) e Myrmosicarius sp. (27 indiv?duos). A primeira esp?cie foi confirmada como uma nova esp?cie e foi mais frequente em ?reas de restinga mais fechadas, enquanto a segunda, em ?reas abertas. As duas esp?cies atacam em trilhas e olheiros. O n?mero de indiv?duos de Myrmosicarius sp. foi influenciado negativamente pela temperatura e positivamente pela umidade relativa do ar. No caso de Neodohrniphora sp. nov., todas as regress?es relacionando o n?mero de indiv?duos capturados com as vari?veis estudadas foram n?o significativas. As esp?cies de for?deos parecem estar associadas a ?reas espec?ficas de restinga, na qual temperatura e umidade s?o fatores limitantes da atua??o dos parasit?ides Myrmosicarius sp., por?m n?o regulam o comportamento parasit?ide de Neodohrniphora sp nov.

The oil drilling and exploration industry creates a substantial amount of waste that, if not adequately disposed of, could cause environmental problems. One of the main contaminates found in the waste related to oil drilling is the element barium. The purpose of this study was to evaluate the contamination of soil containing barium, its impact on the growth of rice plants (Orysa sativa) and potential risk of contaminating groundwater. This paper was divided into four chapters. The goal of the first chapter was to evaluate the spatial variability of barium levels found in former oil well drilling waste disposal sites. For this study, soil was collected from georeferenced points, analyzed in terms of its pseudo total levels, and prepared for the geochemical fractionation of barium, classifying the material in accordance with resolution 420 of CONAMA [Brazilian National Counsel on the Environment] (2009). In the second chapter, the effect of redox potential in soil on the mobility and absorption of barium by rice, having barium sulfate P.A. as the element?s source, was assessed. The effect was evaluated by performing rice culture pot and column leaching tests. The aim of the third chapter was the characterization and traceability of heavy metals in waste generated during the recovery of oil well drilling fluids. The waste was collected during the drilling of well 7-MGP-98D-BA, where the material was separated by composite sample, based on depth and equipment. In the fourth chapter, the effects of redox potential in soil interaction and heavy metals coming from the waste generated from onshore oil well drilling were analyzed. This chapter was similar to chapter two, with the main difference being the waste generated from well 7-MGP-98D-BA, which supplied the source of barium. The waste materials selected were those that displayed the lowest levels of arsenic, cadmium, barium, lead, and sodium. The obtained results showed that waste generated from oil well drilling contains high levels of barium, and that when disposed of in soil can significantly contribute to site contamination, having used the guiding values of CONAMA (2009) as a reference. As such, the barium present in this area was in the form of low solubility, as evidenced by the geochemical fractionation of the element. It was also observed that the conditions of low values of redox potential (-200 mV) promoted an increase of barium in fractions of greater mobility, causing major losses of the element by leaching, and increased absorption by plants. Among the studied waste materials, the waste from the dehydrator and the centrifuge 1 presented high levels of sodium as its greatest limitation, which affected the development of plants. / Apesar da verifica??o de problemas ocasionados pelo uso de produtos gerados a partir da explora??o do petr?leo, essa atividade ? uma realidade nos pr?ximos 50 anos. A industria de perfura??o e explora??o de petr?leo ? uma atividade que gera muitos residuos que, caso dispostos de forma inadequada, podem ocasionar problemas ambientais. Um dos principais contaminantes relacionados aos res?duos de perfura??o de po?os de petr?leo ? o elemento b?rio. A proposta desse estudo foi de avaliar a contamina??o dos solos com b?rio e seu impacto no desenvolvimento de plantas de arroz (Orysa sativa) e o risco de contamina??o do len?ol fre?tico. Para isso o trabalho foi dividido em quatro cap?tulos. O primeiro cap?tulo teve como objetivo avaliar a variabilidade espacial dos teores de b?rio em antiga ?rea de disposi??o de res?duo de perfura??o de po?os de petr?leo. Nesse estudo foram coletados solos em pontos georreferenciados e analisados quanto aos teores pseudototais e feito o fracionamento geoqu?mico do b?rio, classificando o material de acordo com a resolu??o 420 do Conama (2009). No segunto cap?tulo foi avaliado o efeito do potencial redox do solo na mobilidade e absor??o de b?rio por arroz, tendo como fonte do elelmento o sulfato de b?rio P.A. Esse efeito foi avaliado atrav?s de ensaios em vasos com cultivo de arroz e em colunas de lixivia??o. O terceiro cap?tulo teve como objetivo a caracteriza??o e rastreabilidade de metais pesados em res?duos gerados na recupera??o do fluido de perfura??o de po?os de petr?leo. O res?duo foi coletado durante a perfura??o do po?o 7-MGP-98D-BA, onde os materiais foram separados em amostras compostas em fun??o da profundidade e do equipamento. No quarto cap?tulo foi analisado o efeito do potencial redox na intera??o solo e metais pesados provenientes de res?duos oriundos da perfura??o de po?os de petr?leo ?onshore?. Esse cap?tulo foi semelhante ao cap?tulo 2, diferindo principalmente na fonte de b?rio que foi o res?duo gerado no po?o 7-MGP-98D-BA. Os res?duos selecionados foram os que apresentaram como os mais restrit?vos com rela??o aos teores de ars?nio, c?dmio, b?rio, chumbo e s?dio. Os resultados obtidos evidenciaram que os res?duos oriundos da perfura??o de po?os de petr?leo possuem altos teores de b?rio, que quando dispostos nos solos podem contribuir significativamente para a contamina??o das ?reas, tendo como refer?ncia os valores orientadores do Conama (2009). Entretanto, o b?rio presente nessa ?rea estava sob forma de baixa solubilidade, evidenciada pelo fracionamento geoqu?mico do elemento. Tamb?m foi observado que a condi??o de baixos valores de potencial redox (-200 mV) promoveu o aumento do b?rio nas fra??es de maior mobilidade, ocasionando maiores perdas do elemento por lixivia??o e maior absor??o pelas plantas. Dentre os res?duos estudados, os res?duos do secador e da centr?fuga 1 apresentaram como maior limita??o os altos teores de s?dio, o que afetou o desenvolvimento das plantas.

Although the growth regulators are widely studied class, the number of papers describing analytical methods for determining the fluazuron in plasma samples is reduced. The development of a simple and fast analytical method for quantifying fluazuron in bovine plasma by HPLC-UV enables the evaluation of drug plasma profile and can be applied on bioavailability analysis of formulations containing fluazuron. In recent years there has been a technological breakthrough for chromatographic instrumentation, providing rapid, robust and sensitive methods, but the pretreatment of the sample stage becomes the limiting factor in this process. New extraction methods have been developed, however are often complex, expensive methods and are not as sophisticated to handle complex matrices, such as plasma. The aim of this study was a comparative study of three extraction methods: LLE, SPE and matrix solid phase dispersion (MSPD). Pooled plasma samples were used as biological material, partly as raw samples and partly spiked with concentrations of fluazuron. For each extraction method (with exception of DMFS) was conducted using various solvents (ethyl acetate, dichloromethane, diethyl ether, hexane and acetonitrile) in order to evaluate the best extractor solvent. After the extractions the samples were concentrated and analyzed by HPLC/UV. The chromatographic separation was achieved on Kromasil C18 column preceded by guard column of matching chemistry, with mobile phase of acetonitrile: water (80:20, v/v) at flow rate of 1.0 mL/min. The comparative analysis of the extraction procedures was based on selectivity, precision and accuracy of the method. Results showed that LLE not presented accuracy (< 80 and >120%) and precision (CV > 15%) with any solvent tested. SPE method showed good accuracy (80-120%) and precision (CV < 15%) for ethyl acetate, dichloromethane and diethyl ether. MSPD method using ethyl acetate solvent showed good accuracy and precision. However, SPE also allows a lower solvent consumption and shorter analysis time. The validation of the analytical method showed linearity, selectivity, precision, accuracy and, absence matrix effects and residual, thus proving it as suitable for routine analysis; This method showed to be an important investigative tool in the analysis of fluazuron plasma concentration in cattle. Fluazuron topical administration in bovine reached the systemic circulation (Cmax=62,8 ng/mL), was absorbed (tmax=48 hs), while maintaining quantifiable blood plasma levels for up to 14 days after the treatment with a 2,5 mg/Kg dosage. / Fluazuron ? um inibidor do crescimento da classebenzoilfenilur?ia, sendo comercializado para o controle de carrapatos do gado. Embora a classe de reguladores de crescimento sejam amplamente estudada, o n?mero de artigos que descrevem os m?todos anal?ticos para a determina??o do fluazurom em amostras de plasma ? escasso. O desenvolvimento de um m?todo anal?tico simples e r?pido para quantificar fluazuron em plasma bovino por CLAEUV permite a avalia??o do perfil plasm?tico do f?rmaco e pode ser aplicado na an?lise de biodisponibilidade de formula??es contendo fluazurom. Nos ?ltimos anos, tem acontecido um avan?o tecnol?gico para a instrumenta??o cromatogr?fica, proporcionando m?todos r?pidos, eficazes e sens?veis, mas a etapa de pr?-tratamento da amostra torna-se o fator limitante neste processo. Novos m?todos de extra??o t?m sido desenvolvidos, no entanto, muitas das vezes s?om?todos complexos, caros e n?o t?o sofisticados para matrizes complexas como o plasma. O objetivo deste estudo foi um estudo comparativo de tr?s m?todos de extra??o: extra??o l?quido-l?quido (ELL), extra??o em fase s?lida (EFS) e dispers?o de matriz em fase s?lida (DMFS). Ums mistura de amostras de plasma foi utilizada como material biol?gico, uma parte como amostra bruta e outra parcialmente enriquecida com concentra??es de fluazuron. Para cada m?todo de extra??o (exceto DMFS) foram analisadosdiversos solventes (acetato de etila, diclorometano, ?ter diet?lico, hexano e acetonitrila), a fim de avaliar o melhor solvente extrator. Ap?s as extra??es, as amostras foram concentradas e analisadas por CLAE/UV. A separa??o cromatogr?f ica foi obtida na coluna Kromasil C18 precedida de pr?-coluna de fase qu?mica correspondente, com fase m?vel de acetonitrila: ?gua (80:20, v/v) a um fluxo de 1,0 mL /min. A an?lise comparativa dos procedimentos de extra??o foi baseada na seletividade, precis?o e exatid?o do m?todo. Os resultados mostraram que a precis?o ELL n?o apresentou exatid?o (<80 e> 120%) e precis?o (CV> 15%) com nenhum dos solventes analisados. O m?todo EFS mostrou boa exatid?o (80-120%) e precis?o (CV <15%) para o acetato de etila, diclorometano e ?ter diet?lico. O m?todo de DMFS utilizando o solvente acetato de etila mostrou boa exatid?o e precis?o. No entanto, a EFS tamb?m permite um menor consumo de solventes e um tempo curto de an?lise; A valida??o do m?todo anal?tico mostrou linearidade, seletividade, precis?o, exatid?o e, aus?ncia de efeitos de matriz e residual, demonstrando-se adequado para an?lises de rotina; Este m?todo mostrou-se uma ferramenta de investiga??o importante na an?lise de concentra?? plasm?tica em bovinos. Fluazuron administrado por via t?pica em bovinos atingiu a circula??o sist?mica (Cmax = 62,8 ng /ml) e foi absorvido (Tm?x = 48 Hs), se mantendo quantificav?l em n?veis plasm?ticos por at? 14 dias ap?s o tratamento com uma dosagem de 2,5 mg / kg.

Among the many challenges that are brought to this campus for the construction of an education for all, enabling universal access to knowledge and value, while the practices and traditional knowledge of indigenous peoples, is the qualification of teachers in planning mediation of construction of the teaching-learning of indigenous students at the school even other non-indigenous students. The study presented here aimed to investigate which pedagogical concepts teachers use as a basis for organizing their pedagogical work. This is a descriptive characterized as a case study, conducted at the Federal Institute of Education, Science and Technology of the Amazon - Campus S?o Gabriel da Cachoeira, with eleven professors from the Technical Course in Agriculture, which administer the technical disciplines in-vocational education in indigenous communities, as well as on campus. We collected data from four phases of work: Step 1: We did a literature search, which was backed by the theoretical background on the authors to address issues relevant to this study; Step 2: We performed the fieldwork with the course faculty Farming Technician, through questionnaires on educational concepts in school practice as well as on their professional profile; Step 3: analyze their teaching plans, which allowed us to observe how they planned their teaching practice through methodological procedures, the resources that would be used for lessons and evaluation tools; Step 4: We used participant observation to describe the involvement of teachers in the construction of Project Political campus. The material was interpreted from the theoretical framework adopted in which content analysis was used for this purpose. In seeking to understand how teachers organized both his pedagogical work, such as the Educational Policy Project of the campus, we realize that they do not understand that there is a relationship between education and society, therefore, have no understanding of the meaning of education to society where the campus is inserted and therefore there is a pedagogical concept defined the reasons for organizing their pedagogical work. To meet the multi-ethno-cultural in that region, allowing a differentiated model of education, constant updating is a fundamental need and unambiguous, and therefore stress the importance of such training to promote the continuous development of teachers, with actions that lead to investigate, search and interact, enabling the expansion of their knowledge and resilience, both in its design in relation to education, the challenges and problems of their everyday school life. / O Instituto Federal de Educa??o, Ci?ncia e Tecnologia do Amazonas ? Campus S?o Gabriel da Cachoeira situa-se no alto Rio Negro, Amazonas, onde convivem povos ind?genas de v?rias etnias com diferentes l?nguas, usos, costumes e tradi??es. Entre os muitos desafios que est?o postos a este campus para a constru??o de uma educa??o para todos, que possibilite acesso aos conhecimentos universais e valorize, ao mesmo tempo, as pr?ticas e saberes tradicionais das popula??es ind?genas, est? o da qualifica??o dos professores em planejar a media??o da constru??o do processo ensino-aprendizagem de alunos ind?genas, no mesmo espa?o escolar de outros alunos n?o ind?genas. O estudo aqui proposto teve por objetivo investigar quais concep??es pedag?gicas os professores utilizam como base para a organiza??o do seu trabalho pedag?gico. Trata-se de uma pesquisa descritiva caracterizada como um estudo de caso, realizada no Instituto Federal de Educa??o, Ci?ncia e Tecnologia do Amazonas ? Campus S?o Gabriel da Cachoeira, com onze professores do Curso T?cnico em Agropecu?ria, os quais ministram disciplinas da ?rea t?cnico-profissionalizante em comunidades ind?genas, assim como no campus. Realizamos a coleta de dados a partir de quatro etapas de trabalho: Etapa 1: fizemos uma pesquisa bibliogr?fica, onde houve o respaldo do embasamento te?rico nos autores que tratam das quest?es pertinentes ao presente estudo; Etapa 2: realizamos a pesquisa de campo com os professores do curso T?cnico em Agropecu?ria, por meio de question?rios sobre as concep??es pedag?gicas em sua pr?tica escolar, bem como sobre o seu perfil profissional; Etapa 3: analisamos seus planos de ensino, os quais nos permitiram observar como planejavam sua pr?tica pedag?gica, atrav?s dos procedimentos metodol?gicos, os recursos que seriam utilizados para as aulas e os instrumentos de avalia??o; Etapa 4: utilizamos a observa??o participante para descrever a participa??o desses professores na constru??o do Projeto Pol?tico Pedag?gico do campus. O material coletado foi interpretado a partir do marco te?rico adotado onde utilizamos a an?lise de conte?do para esse fim. Ao procurarmos conhecer como os professores organizaram, tanto seu trabalho pedag?gico, como o Projeto Pol?tico Pedag?gico do campus, percebemos que os mesmos n?o entendem que h? uma rela??o entre educa??o e sociedade, em consequ?ncia, n?o possuem um entendimento do sentido da educa??o para a sociedade em que o campus est? inserido e, portanto, n?o existe uma concep??o pedag?gica definida que fundamente a organiza??o de seu trabalho pedag?gico. Para atender a diversidade etno-pluri-cultural dessa regi?o, viabilizando um modelo de educa??o diferenciada, a atualiza??o permanente ? uma necessidade fundamental e inequ?voca, portanto, enfatizamos a import?ncia dessa forma??o para promover o desenvolvimento cont?nuo dos professores, com a??es que o levem a investigar, pesquisar e interagir, possibilitando a amplia??o de seus conhecimentos e a supera??o, tanto de sua concep??o em rela??o ? educa??o, quanto dos desafios e problemas do seu cotidiano escolar.

The treatments consisted of 2 pastures, one of grassonly Brachiaria humidicola (Rendle) Schweickt, and the other of B. humidicola consorted with Desmodium ovalifolium Wall cv. Itabela, each grazed at 3 different stocking rates of 2, 3 and 4 animals per hectare. Estimates of animal intake under grazing were made at two occasions during the year (August and November of 1995). Six oesophagus-fistulated steers were used for sampling of the consumed forage, and 36 animals were fed with 10 g of Cr2O3 each day, for 21 days. The ?in vitro? digestibility of dry matter, total nitrogen, and natural abundance of 13C were analyzed in the fistula samples. At the same time, the productivity of the pastures and their botanical composition was measured. The presence of the legume D. ovalifolium in the pastures of B. humidicola increased the protein content of the forage ingested by the animals by 64%. The dry matter intake was affected negatively by the presence of the legume due to its low palatability, however the proportion of the legume in the diet was quite significant (27 to 62%), being highest in the higher stocking rates due to the more restricted selectivity of the grazing animals. At the lower stocking rate there was a larger proportion of the legume in forage on offer. The total protein intake by the animals was higher in mixed pastures, but that didn't provide a better animal performance due to low digestibility of the legume. The rate of decomposition was very rapid (k ~ -0.081 and 0.060g g-1 day-1) P and K, and annual rates of P turnover through the litter pathway were between 13.7 and 13.2 kg P ha-1 year-1. In the grass-only pastures, as stocking rate increased from 2 to 3 head ha-1, P recycled in the litter decreased by 11%, but a further increase to 4 head ha-1 decreased P recycling by 6%, suggesting that beyond a certain critical level higher grazing stocking rates would lead to pasture decline if there was no N addition. High stocking rates decreased proportion of the legume in the sward, but at all rates the concentration of P in both the green and dead grass, in the forage on offer and in the litter, was higher in the mixed sward. The presence of legume in the litter resulted in increases in P and K recycled via litter deposition varying from 12.5 to 14.3 kg P ha-1 year-1 and 25.0 to 37.6 kg K ha-1 year--1. / Esse experimento foi conduzido na Esta??o Experimental de Zootecnia do Extremo Sul da Bahia (ESSUL/CEPEC/CEPLAC) obedecendo a um delineamento experimental inteiramente casualizado, com 6 tratamentos e 3 repeti??es. Os tratamentos foram estabelecidos segundo um fatorial 2 x 3, com 2 pastagens, Brachiaria humidicola (Rendle) Schweickt em monocultura e B. humidicola consorciada com Desmodium ovalifolium Wall cv. Itabela, e 3 taxas de lota??o, 2, 3 e 4 cabe?as por hectare. A estimativa do consumo animal em pastejo foi avaliada em 2 ?pocas do ano (agosto e novembro de 1995). Utilizaram-se 6 animais bovinos es?fago-fistulados para a retirada das extrusas (dietas consumidas) e 36 bovinos foram dosados com 10 g de Cr2O3 por dia, durante 21 dias. A digestibilidade ?in vitro? da mat?ria seca e a abund?ncia natural do 13C foram analisadas nas extrusas. Paralelamente, foram avaliadas a produtividade das pastagens e a sua composi??o bot?nica. O consumo de mat?ria seca foi afetado negativamente pela presen?a da leguminosa D. ovalifolium nas pastagens de B. humidicola devido ? sua baixa palatabilidade, por?m a propor??o da leguminosa na dieta consumida foi bastante significativa, sendo maior nas taxas de lota??o mais elevadas onde a seletividade dos animais foi mais restrita, apesar do fato de que na menor taxa de lota??o havia uma maior propor??o da leguminosa na forragem em oferta. O menor consumo de forragem observado nas pastagens consorciadas, n?o proporcionou menor desempenho animal, provavelmente devido ? maior oferta de prote?na oferecida pela leguminosa. As altas taxas de lota??o provocaram uma diminui??o na propor??o de leguminosas na forragem em oferta, entretanto em todas as taxas de lota??o a concentra??o de P na gram?nea verde e seca da forragem em oferta e da liteira foi maior nas pastagens consorciadas. A taxa de decomposi??o da liteira foi muito elevada, cerca de 0,081 e 0,060 g g-1 dia-1, para P e K respectivamente, acarretando uma deposi??o anual de P pela liteira entre 13,2 e 13,7 kg P ha-1 ano-1. Nas pastagens em monocultura, os aumentos na taxa de lota??o de 2 para 3 animais ha-1 e de 3 para 4 animais ha-1 causaram decr?scimos na reciclagem de P na liteira de respectivamente, 11 e 6%.Provavelmente essas altas taxas de lota??o provocam um decl?nio das pastagens devido ? menor adi??o de P ao sistema solo.

Considered an oil of high economic value because this has a clearly defined market for the oil extracted from its seeds. The cake, which is a residue of this extraction, stands out for its high protein content. Among the proteins found in the cake stands ricin, a cytotoxin, which not allows its use as an alternative protein source for animal feed. In this study was used the extrusion-cooking technology, combined application of calcium hydroxide Ca(OH)2 in order to inactivate the protein fraction containing ricin. The extrusion process of cake castor oil was carried out using a Brabender DS20 cannon short. Was used the response surface methodology to investigate the effect of the interaction of parameters in the study. Was used a central composite design in order to evaluate the moisture effects (14%, 16%, 18%, 20%, and 21%), temperature (116?C, 130?C, 150?C, 170?C and 180?C) and concentration of Ca(OH)2.. As a comparative sample was used castor beans which were crushed to extract oil and cake which used as a sample without heat treatment, as standard. For the evaluation of physical-chemical, it was utilized methods of AOAC. The quantification of proteins was realized using the method of Bradford and the protein profile was electrophoresis-SDS-PAGE. Was used to mark the Biorad electrophoresis the methodology observed using the of preparation of the gels described by LaemmLi (1970). The results indicated that most of the different treatments performed totally changed the structure of ricin. Indizatily the possibility of total hydr?lise of this macromolecule. The application of extracts of castor oil in the gel electrophoresis allowed the observation of a clear chain A (RTA) and 38 kDa molecular weight B (RTB) molecular weight 36kDa. For the crude protein extract of bran molar mass chains A and B were approximately 37 kDa and 35 kDa respectively. The levels of protein extracted from the bran decreased 89% after extrusion. The results indicated that all treatments changed entirely the structure of ricin with the possibility of their having been a total hydrolysis of the polymer. According to tests performed and observed results, we conclude that the thermoplastic extrusion process is a suitable technology to decrease the activity of ricin / A mamoneira (Ricinus communis L.) ? uma planta da fam?lia Euforbi?cea que vem sendo muito estudada como fonte alternativa na produ??o de biodisel. O farelo, res?duo gerado ap?s a extra??o do ?leo da semente utilizando solvente, apresenta alto teor de prote?nas. Dentre as prote?nas encontradas na torta destaca-se a ricina, uma citotoxina, que inviabiliza sua utiliza??o como fonte prot?ica alternativa para alimenta??o animal. No presente estudo empregamos a extrus?o termopl?stica, associada ? aplica??o de hidr?xido de c?lcio Ca (OH)2 com o objetivo de inativar a fra??o prot?ica que contem a ricina. O processo de extrus?o do farelo de mamona foi realizado utilizando uma extrusora BRABENDER DS20 de canh?o curto. Utilizou-se a metodologia de superf?cie de resposta para verificar o efeito da intera??o dos par?metros estabelecidos no estudo. Foi utilizado um delineamento composto central rotacional a fim de avaliar os efeitos dos n?veis de umidade (14%, 16%, 20% e 21%), temperatura (116?C, 130?C, 150?C, 170?C e 180?C) e concentra??o Ca(OH)2.. Como amostra comparativa foi utilizada sementes de mamona da cultivar Paragua?? as quais foram esmagadas em prensa expeller at? extrair o ?leo e cuja torta foi utilizada como padr?o por apresentar maior integridade das cadeias polipept?dicas. Para a avalia??o das caracter?sticas f?sico-qu?micas, foram utilizados m?todos da AOAC, para quantifica??o de prote?nas foi utilizado o m?todo de Bradford e para avalia??o do perfil prot?ico foi utilizada a eletroforese- SDS-PAGE, atrav?s do sistema de eletroforese da marca Biorad com a metodologia de prepara??o dos g?is descrita por Laemmli (1970). Os m?todos de purifica??o usando a di?lise e precipita??o com sulfato de am?nio favoreceu para um bom rendimento quanto ao teor de prote?na, principalmente a ricina. A aplica??o dos extratos da torta de mamona no gel de eletroforese permitiu a observa??o n?tida das cadeias A (RTA) massa molar 38 kDa e B (RTB) massa molar 36kDa. Para o extrato prot?ico do farelo bruto a massa molar das cadeias A e B ficaram em torno 37 kDa e 35 kDa respectivamente. Os n?veis de prote?na extra?da do farelo diminu?ram 89% ap?s a extrus?o. Os resultados indicaram que todos os tratamentos realizados modificaram totalmente a estrutura da ricina, com possibilidade de ter havido hidr?lise total desta macromol?cula. De acordo com os ensaios realizados e resultados observados, conclui-se que o processo de extrus?o termopl?stica ? uma tecnologia adequada para diminuir a atividade da ricina.

This conflict revolved around the street shoe trade, which sought to prohibit the brotherhood. Within this context, we seek to address such a fellowship as a brotherhood of office, wich had the organizational model of the mechanical crafts of the Kingdom as a parameter, but it was so specific, as long as it were part of a slave society. On the other hand, the period in discussion is highlighted, drawing attention to the continuities and discontinuities that was contained in it. Thus, there is the commitment of these shoemakers confreres in maintaining an institution that forged a monopolistic structure to a certain sector of the retail trade, this institution which found its legitimacy as a reference an array of Iberian corporatism. Thus, referring to the values and codes of the Ancient Regime, as a commitment to dissociate his office of the slavery, or as trying to keep "black lining" and "free mulatto" under their control, defining hierarchical gradations leading into account the criterion of color. At the same time, major changes were underway in the Portuguese Empire and the city of Rio de Janeiro, whether political, administrative, social, cultural, or in the framework of ideas (the Enlightenment, liberalism). Thus, in the twenties of the nineteenth century, the council members had become more firmly against the intention of St. Crispin?s cobblers in the prohibition of the trade in footwear through the streets of the city, which points to the adaptation and dissemination of the liberal ideas within the court itself and among the elite that made up the City Council, despite the social principles in hierarchies make sense also for this social segment. To the brothers of the Brotherhood of St. Crispim and St. Crispiniano, they only had to fight within the legal and institutional mechanisms that shaped itself to new times, but still had a strong element of continuity with the values and practices of the Ancient Regime, reported by Portugal. / O presente trabalho busca abordar o conflito entre a Irmandade de S. Crispim e S. Crispiniano e a C?mara do Rio de Janeiro, entre 1764 e 1821, per?odo em que se p?de verificar o mencionado conflito. O mesmo girava em torno do com?rcio ambulante de cal?ados, o qual a irmandade buscava proibir. Dentro deste contexto, procura-se abordar a referida irmandade como uma irmandade de of?cio, que tinha o modelo de organiza??o dos of?cios mec?nicos do Reino como par?metro, mas que se constituiu de forma espec?fica, j? que se inseria numa sociedade escravista. Por outro lado, destaca-se o per?odo abordado, chamando aten??o para as continuidades e descontinuidades que o mesmo comportava. Sendo assim, verifica-se o empenho desses confrades sapateiros na manuten??o de uma institui??o que forjava uma estrutura monopolista para determinado setor do com?rcio a varejo, institui??o esta que encontrava sua legitimidade tendo como refer?ncia uma matriz do corporativismo ib?rico. Desta maneira, remetiam-se a valores e c?digos de Antigo Regime, fosse no empenho em dissociarem o seu of?cio em rela??o ? escravid?o, fosse na tentativa de manterem ?pretos forros? e ?pardos livres? sob seu controle, definindo grada??es hier?rquicas que levavam em conta o crit?rio da cor. Ao mesmo tempo, mudan?as importantes encontravam-se em curso no ?mbito do Imp?rio Portugu?s e da cidade do Rio de Janeiro, fossem elas no campo pol?tico, administrativo, social, cultural, ou no campo das ideias (iluminismo, liberalismo). Assim, na d?cada de vinte do s?culo XIX, os vereadores apresentavam-se mais firmemente contra a inten??o dos sapateiros de S. Crispim em proibir o com?rcio de cal?ados pelas ruas da cidade, o que apontava para a dissemina??o e adapta??o das ideias liberais no seio da pr?pria corte e entre a elite que compunha a C?mara, n?o obstante os princ?pios sociais hierarquizantes fizessem sentido, igualmente, para este segmento social. Aos confrades da Irmandade de S. Crispim e S. Crispiniano, restava lutar no interior dos mecanismos legais e institucionais que se moldavam a novos tempos, mas que ainda guardavam uma forte componente de continuidade em rela??o aos valores e pr?ticas de Antigo Regime, comunicados por Portugal

For that we have analyzed the Campaign for the Production of Healthy Food, trying to understand how this practices represent questioning, resistence and confrontation of the diverse ways by wich capitalism and patriarchy are expressed in their realities. Through the identification of some actions related to the campaign we have tried to realize how this actions have a sense of democratization of the public sphere and broaden the access to social rights (education, health, water, agro-ecological production, the struggle to preserve native seeds, medicinal herbs and valuing peasant culture). The idea is based in the possibility of situating our view within the political, cultural and theoretical universe in which the issues of gender and food sovereignty have come to evidence. Another issue is the use o food sovereignty as a political tool for strengthening the struggle of social movements and its definition as one of the axis of the MMC political project. Thus, we have carried out an ethnographic study with the campaign facilitators in the State of Santa Catarina. We have followed the activities of five facilitators for twenty three days and visited six groups in five different cities, in the effort of identifying and observing the characteristics or the practices and strategies of women groups involved in the Campaign for the Production of Healthy Food an in the Native Seeds Rescue, Production and Improvement Program. Through a systematization of some data, our proposal is to discuss and try to find answers for a few questions as: how does an approach based on gender issues can contribute to the debate on food sovereignty? How through this campaign is food sovereignty becoming a political project for the MMC? What are the difficulties that peasant women see in implementing this campaign? How is the struggle of women for food sovereignty broadening and brings democracy to public space? How is the struggle for food sovereignty combined with the struggles for access to water, education, welfare and other? / A proposta desta disserta??o ? analisar a rela??o entre as mulheres agricultoras que participam do Movimento de Mulheres Camponesas/MMC e a Soberania Alimentar a partir da sua pr?tica, sendo o MMC o ?nico movimento feminista que participa da Via Campesina no Brasil. Para tal, foi analisada a Campanha pela Produ??o de Alimentos Saud?veis buscando perceber como essas pr?ticas representam o questionamento, a resist?ncia e o enfrentamento das diversas formas pelas quais se expressam em suas realidades o capitalismo e o patriarcado. A partir da identifica??o de algumas a??es relacionadas ? campanha, buscamos perceber como estas democratizam a esfera p?blica e ampliam o campo de acesso aos direitos sociais (educa??o, sa?de, acesso ? ?gua, produ??o agroecol?gica, a luta pelo resgate das sementes crioulas, plantas medicinais e a valoriza??o da cultura camponesa). A ideia se constitui na possibilidade de nos situarmos dentro do universo social, pol?tico e te?rico, no qual as quest?es sobre g?nero e soberania alimentar tem se apresentado. Outra quest?o que foi abordada ? a o uso da soberania alimentar como instrumento pol?tico que fortalece a luta dos movimentos sociais e sua defini??o enquanto um dos eixos do projeto pol?tico do MMC. Para tal, foi realizada uma pesquisa etnogr?fica com as monitoras da campanha no estado de Santa Catarina. Durante 23 dias as atividades de cinco monitoras foram acompanhadas. Seis grupos em cinco cidades foram visitados, para identificar e caracterizar as estrat?gias e as pr?ticas dos grupos de mulheres que est?o envolvidas na campanha pela produ??o de alimentos saud?veis e no Programa de Recupera??o, Produ??o e Melhoramento das Sementes Crioulas. A partir da sistematiza??o de alguns dados, a proposta ? discutir e tentar responder a algumas quest?es: em que medida uma abordagem de g?nero enriquece a discuss?o sobre soberania alimentar? Como a soberania alimentar, por meio das a??es da campanha, se constitui em projeto pol?tico do MMC? Quais as maiores dificuldades que as mulheres camponesas enfrentam na implementa??o da campanha? De que forma a luta das mulheres por soberania alimentar amplia e democratiza o espa?o p?blico?

This work had the purpose to know the Social Representations of Cacha?a and its relationship with the consumption of alcohol for students in the course of Technology in the Production of Cacha?a of Federal Institute of the North of Minas Gerais (IFNM) -Campus Salinas. Using the diagnosis of factors that had motivated these young people for this college course, to identifying if the consumption and the conceptions about cacha?a at these young people were affected by this college course, as well as the factors that the students has related for to drinking cacha?a as: occasions, friendship, the correlation with the family habits, the risks to health and social problems. The research was carried out in IFNMG, in the year 2010, with forty-eight students in the upper course of Technology in the Production of Cacha?a. It was consisted of three stages: 1- socioeconomic characteristics of students, with structured questions; 2- Evaluation of the knowledge of the students about cacha?a that understood the use of a Likert scale of five points; 3- Social representation of the cacha?a with roadmap built with open-ended questions, in order to encourage the discourse, and the interviews were recorded, transcribed and analyzed by technique of the Collective Subject Discourse, on the basis of the theory of Social Representations, using the software Qualiquantisoft. Thus, it was found that the universe of the students presents a predominance of women (62.5 %) and the age range of 18 to 21 years old (56.2 % ). The majority (87 % ), concluded the middle school at a public school in regular course (90 %) and are living in an urban area (81 %) in the city of Salinas (86 % ). On the social representations for the consumption of alcohol, the students have attitudes predominantly unfavorable to the consumption of alcoholic beverages; they hadn't believe that the young people has drunk alcohol for "to feel sad or annoying" or "feel more integrated and identified with their group"; the motivation more favorable on the consumption of alcoholic beverages were "to relax or calm down the nerves" and "to feel more adults". In terms of Knowledge and Beliefs, the students believe that alcohol can cause physical dependence" and the consumption of cacha?a "helps to unwind/ encourage". It was verifie that the social representations of students about the properties and the consumption of alcoholic beverage and cacha?a, presents a great level of information and they has attitudes predominantly negative in relation to alcohol consumption. The representation to the attraction of the cacha?a from Salinas, it was found that "The fame of the cacha?a and the city" as the most prevalent among the answers. Therefore, for these students, the biggest attraction of cacha?a of Salinas maintains a direct correlation with the marketing that has been attributed to the cacha?a this region. However, they have believed on the factors of quality of the cacha?a once they showed an expressive representation in the categories involved in the production and quality as: "sensory attributes", "quality" and "manufacture craft". / As Representa??es Sociais s?o estruturas de conhecimento individuais, compartilhadas, que permitem a um grupo entender uma realidade, manter sua integridade, direcionar e fundamentar suas pr?ticas. Esta pesquisa teve como prop?sito conhecer as Representa??es Sociais da Cacha?a e a sua rela??o com o consumo de ?lcool para alunos do curso superior Tecn?logo em Produ??o de Cacha?a do no Instituto Federal do Norte de Minas Gerais (IFNM)-Campus Salinas, atrav?s do diagn?stico dos fatores que motivaram o ingresso desses jovens neste curso; identificando se o consumo de e as concep??es sobre cacha?a pelos jovens foram afetados pelo seu ingresso no curso, bem como os fatores que os alunos relacionam com ato de beber cacha?a como: ocasi?es, companhias, a correla??o com os h?bitos familiares, os riscos ? sa?de e problemas sociais. A pesquisa foi realizada no IFNMG, no ano de 2010, com quarenta e oito alunos do curso superior de Tecnologia em Produ??o de Cacha?a e consistiu de tr?s etapas: 1-a caracteriza??o socioecon?mica dos discentes com um roteiro estruturado; 2-a avalia??o do conhecimento dos alunos sobre cacha?a que compreendeu a utiliza??o de uma escala do tipo Likert de cinco pontos; 3- a pesquisa de representa??o social da cacha?a com roteiro constru?do com quest?es abertas, a fim de incentivar o discurso, sendo os discursos gravados, transcritos e analisados pela t?cnica do Discurso do Sujeito Coletivo, com base na teoria das Representa??es Sociais, utilizando o software Qualiquantisoft. Assim, verificou-se que o universo dos sujeitos do presente estudo apresenta um predom?nio de mulheres (62,5%) e a faixa et?ria de 18 a 21 anos de idade (56,2%). A sua maioria (87%), concluiu o ensino m?dio em escola p?blica, em curso regular (90%) e s?o residentes em ?rea urbana (81%) no munic?pio de Salinas (86%). Nas representa??es sociais sobre o consumo de ?lcool, os sujeitos desta pesquisa apresentam atitudes predominantemente desfavor?veis ao consumo de bebidas alco?licas; n?o acreditam que os jovens bebam por ?se sentirem tristes ou aborrecidos? ou para ?se sentirem mais integrados e identificados com o seu grupo?; as motiva??es mais favor?veis sobre o consumo de bebida alco?lica foram ?para relaxar ou acalmar os nervos? e ?para se sentirem mais adultos?. Quanto ao Conhecimento e Cren?as eles acreditam que o ?lcool ?pode causar depend?ncia f?sica? e o consumo de cacha?a ?ajuda a descontrair/ desinibir?.

For this, start with the premise that the main topic of organizational change, at the last decades, includes the structure of organizations. These changes are a reaction of the organizations to the merchandizing intense pressures that amplified the level of competitivity. In such case, the establishment of contributing relations appeared as a strong tool of organizational development, however caused a change on the way of observing the enterprises. Under this context, the traditional strategic planning becomes an analyzed target in virtue of this new organizational environment that is formed when the conception of the structures at networks of enterprises. The general objective in this dissertation consist to promote a comparative analysis of the process of Strategic Planning (SP) between an enterprise of traditional pattern and an inter-worknets networks, in function of the contrast among the organizational environments. For this, will be analyzed the construction of the strategic planning at a traditional enterprise environment (only one enterprise) establishing a comparison with the same process at an inter-worknet network (enterprises in network). It is suppose that the network organizational environment differs from the traditional organizational environment. This way, the process of strategic planning is different by strength of structural divergence among the organizational environments. The objective of this study is to explain possible divergences at the elaboration of the SP between the environments in this study called: traditional and inter-worknets networks. Supplementary the study presume that the process of strategic planning permit the access of information and privileged recourses that processed enables the development of the knowledge of organizations and becomes an important tool to the organizational development. Such suppositions and objectives were reached based on a structured questionary and personal interview with managers of Strategic Planning of the two researched enterprises. Both of them are recognized on the national and international scenario representing the relevance of the study. / O presente trabalho analisa o ambiente empresarial tradicional e o ambiente de redes interorganizacionais quando da elabora??o do planejamento estrat?gico (PE). Para tal, partese da premissa de que o principal t?pico de mudan?a organizacional, nas ?ltimas d?cadas, envolve a estrutura das organiza??es. Tais mudan?as s?o rea??es das organiza??es ?s fortes press?es mercadol?gicas que elevaram o n?vel de competitividade. Assim, o estabelecimento de rela??es colaboradoras surgiu como forte ferramenta de desenvolvimento empresarial, entretanto acarretou na mudan?a da forma com que se observam as empresas. Neste contexto, o planejamento estrat?gico tradicional torna-se alvo de an?lise em virtude deste novo ambiente organizacional que se forma quando da concep??o de estruturas em redes de empresas. O objetivo geral nesta disserta??o consiste em promover uma an?lise comparativa do processo de Planejamento Estrat?gico (PE) entre uma empresa de formato tradicional e uma rede interorganizacional, em fun??o do contraste entre os ambientes organizacionais. Para tanto, ser? analisada a constru??o do planejamento estrat?gico em um ambiente empresarial tradicional (uma ?nica empresa) estabelecendo uma compara??o com o mesmo processo em uma rede interorganizacional (empresas em rede). Sup?e-se que o ambiente organizacional em rede difere-se do ambiente organizacional tradicional. Desta forma, o processo de planejamento estrat?gico ? diferenciado por for?a da diverg?ncia estrutural entre os ambientes organizacionais. O objetivo do presente estudo ? interpretar poss?veis diverg?ncias na elabora??o do PE entre os ambientes neste estudo denominados: tradicional e redes interorganizacionais. Complementarmente o estudo sup?e que este processo de planejamento estrat?gico permite o acesso a informa??es e recursos privilegiados que processados possibilitam o desenvolvimento do conhecimento das organiza??es e, portanto, torna-se ferramenta importante para o desenvolvimento organizacional.
