The Serrana Region of Rio de Janeiro State was chosen as study area because in it land structure predominates small rural properties, of family farming. This Region has the second major reforestation area of the State. As the topic of family forestry production has been little discussed in academic level, this essay is an exploratory research, with a collective case study. The presence or absence of forestry activities in the small properties of the region, as well as the supply and the demand of wood products in local level was obtained through secondary data. The analysis of the family producers? silvicultural system, in terms of management and production costs, availed information collected through interviews with technicians and local farmers. The study showed that the forestry production in familiar farming in the Serrana Region has potential to supply the wood local market. The forestry activities has great value to diversify the rural landscape and combating illegal logging of tropical forests. There is still a lot of resistance to these activities by farmers, given the history of eucalyptus monoculture expansion. Other species with silvicultural potential, and suitable to the small and medium farmers management, should be studied to meet the market demands. The forest element must bring a ransom and a respect to the traditional management and the way the activities are performed into each farm, in the life of each family, in the way of more sustainable activities. / O presente estudo procura apresentar a din?mica da produ??o florestal em propriedades de agricultura familiar, no sentido de compreender a pr?tica do manejo usual nessas propriedades, perceber os interesses dos produtores nas atividades florestais, e a capacidade dessas atividades para abastecer o mercado local de madeira. A Regi?o Serrana do Estado do Rio de Janeiro foi escolhida como ?rea de estudo pois sua estrutura fundi?ria se caracteriza pela predomin?ncia de pequenas propriedades rurais, de produ??o principalmente familiar. Esta regi?o se destaca por ter a segunda maior ?rea de plantios de reflorestamento do Estado, e tem como foco principal o abastecimento do mercado local. Visto que o tema da produ??o florestal familiar tem sido pouco discutido no ?mbito acad?mico, este trabalho se caracteriza como uma pesquisa explorat?ria, a partir de um estudo de caso coletivo. A presen?a ou aus?ncia da atividade florestal nas pequenas propriedades da regi?o, bem como as rela??es de oferta e demanda de produtos madeireiros a n?vel local foram obtidas de dados secund?rios. J? a an?lise do sistema silvicultural utilizado pelos produtores, em termos de manejo e custos de produ??o, foi realizada a partir das informa??es obtidas dos depoimentos de t?cnicos e produtores locais. Neste trabalho, notou-se que a produ??o florestal que ocorre em propriedades de agricultura familiar na Regi?o Serrana apresenta potencial para abastecer o mercado local de madeira. As atividades florestais t?m grande import?ncia para a diversifica??o da paisagem rural e no combate ? extra??o ilegal de madeira nativa de florestas tropicais. Ainda h? muita resist?ncia a essas atividades por parte dos agricultores, visto o hist?rico da expans?o dos monocultivos de eucalipto. Outras esp?cies com potencial silvicultural, e adequadas ao sistema de manejo existente nas pequenas e m?dias propriedades, devem ser estudadas para atender as demandas do mercado. A inser??o do elemento florestal deve trazer um resgate e um respeito ao manejo tradicional e ? forma como as atividades s?o realizadas dentro de cada propriedade, na viv?ncia de cada fam?lia, no caminho em dire??o a atividades mais sustent?veis.

This experiment aimed to develop a quantitative measurement equipment in tear production similar to the ZoneQuick? Menicon and improve it, establish a pattern of reading to those and evaluate their advantages and disadvantages. For that, we selected 50 beagle dogs, male and female, aged 1-8 years from the Canil do Laboratorio de Quimioterapia Experimental Parasitol?gica of UFRRJ, and produced two tests with Cotton Thread with Phenol Red and Bromocresol Green. Afterwards was made the reading standization of those three tests compared to the Schirmer tear test, getting as normal range of reading for the tests with Cotton Thread with Phenol Red 13.6 to 22.7 mm/15seg., the ZoneQuick? Menicon of between 22, 7 and 37.8 mm/15seg. and tests with Cotton Thread with the Bromocresol Green 13.7 to 22.8 mm/15seg.. Among those three tests, the ZoneQuick? showed the smallest shift in color of the indicator and the largest Cotton Thread with the Bromocresol Green which along with the smaller standard error presented by this facilitates its reading and reduces the chance of false positive or negative. In a comparison between the Schirmer Tears Test , Cotton Thread with the Bromocresol Green tests and Cotton Thread with Phenol Red latter, generated less reflex tear production, with a reading closer to the real. / Em rela??o ? mensura??o da produ??o lacrimal, a t?cnica de leitura lacrimal com o fio de algod?o embebido em uma solu??o indicadora de pH vem se mostrando vantajosa em rela??o ao Teste Lacrimal de Schirmer I (TLS I) em diversos estudos, devido ? menor largura do material de teste e tempo de realiza??o deste, o que leva a uma menor produ??o lacrimal reflexa e uma leitura mais pr?xima da produ??o lacrimal basal ou real. Este experimento teve como objetivos, testar diferentes tipos de fios e avaliar qual o mais indicado a realiza??o dos testes, desenvolver um material de medi??o quantitativo da produ??o lacrimal de fio impregnado com vermelho fenol, testar outro indicador de pH, estabelecer um padr?o de leitura para estes e o ZoneQuick? da Menicon e compar?-los ao TLS I avaliando suas vantagens e desvantagens. Para isto, foram selecionados 50 c?es da ra?a Beagle, machos e f?meas, com idade variando de 1 a 8 anos do Canil do Laborat?rio de Quimioterapia Experimental Parasitol?gica da UFRRJ, e produzidos dois testes com Fio de Algod?o impregnados com Vermelho Fenol ou Verde de Bromocresol. Em seguida foi feita a padroniza??o da leitura dos tr?s testes em compara??o ao TLS I, obtendo-se como faixa normal de leitura para o Teste de Fio de Algod?o com Vermelho Fenol de 13,6 a 22,7 mm/15seg., o ZoneQuick? da Menicon entre 22,7 e 37,8mm/15seg. e o Teste de Fio de Algod?o com Verde de Bromocresol de 13,7 a 22,8 mm/15 seg.. Dentre os tr?s testes, o ZoneQuick? apresentou a menor viragem na cor do indicador e o Teste de Fio de Algod?o com Verde de Bromocresol a maior o que, juntamente com o menor erro padr?o por este apresentado, facilita sua leitura e reduz a chance de falso positivo ou negativo. Na etapa de compara??o entre os TLS I, Fio de Algod?o com Verde de Bromocresol e Fio de Algod?o com Vermelho Fenol este ?ltimo gerou menor produ??o lacrimal reflexa, com uma leitura mais pr?xima da real.

For that, the study was divided in two chapters, structured in the shape of a scientific paper. The first is a theoretical proposition on the occupation of the APPs in light of the discussion of the geographic space and the sustainability of the development, where a bibliographical review was made emphasizing the production of the geographic space, the sustainability of the development and the permanent preservation areas. In the second chapter, from a systemic approach, geoprocessing techniques and the adaptation of the Pressure-State- Response Indicators System were used, the latter being developed by the Organization for Economic Co-operation and Development OECD. Therefore, from the methodological approaches used, it's been observed that the use of permanent preservation areas for purposes other than those determined in the legislation and, mainly guided by capitalist interests, leads to the environmental degradation of these areas, fact which has been confirmed in the empiric study conducted in the second chapter, where it was possible to identify a series of environmental impacts such as: deforestation of mangrove and riparian vegetation for carciniculture implantation, the devastation of dune areas caused by the urban expansion in the coastal stretch and siltation of fluvial channel / O objetivo desta disserta??o ? identificar e analisar os principais impactos ambientais ocorrentes nas ?reas de preserva??o permanente localizadas no estu?rio do Rio Cear?-Mirim/RN e suas ?reas adjacentes. Para isto, o estudo foi dividido em dois cap?tulos estruturados em forma de artigo cient?fico. O primeiro ? uma proposi??o te?rica sobre a ocupa??o das APPs a luz da discuss?o do espa?o geogr?fico e da sustentabilidade do desenvolvimento, onde foi feita uma revis?o bibliogr?fica enfatizando a produ??o do espa?o geogr?fico, a sustentabilidade do desenvolvimento e as ?reas de preserva??o permanente. No segundo cap?tulo, a partir de uma abordagem sist?mica foram utilizadas t?cnicas de geoprocessamento e a adapta??o do Sistema de Indicadores Press?o-Estado Resposta, desenvolvido pela Organization for Economic Cooperation and Development OECD. Desta forma, a partir das abordagens metodol?gicas utilizadas, observou-se que a utiliza??o de ?reas de preserva??o permanente para fins diferentes do que est? posta na legisla??o e, principalmente guiada por interesses capitalistas, leva a degrada??o ambiental destas ?reas, fato confirmado no estudo emp?rico realizado no segundo cap?tulo, onde foi poss?vel identificar uma s?rie de impactos ambientais como: desmatamento de vegeta??o de mangue e de mata ciliar para implanta??o da carcinicultura, a devasta??o de ?reas de dunas provocada pela expans?o urbana na faixa litor?nea e assoreamento de canal fluvial

Tendo em vista o contexto da pesquisa e por se tratar de uma institui??o p?blica, fez-se a revis?o bibliogr?fica sobre Administra??o P?blica, enfatizando os princ?pios basilares expressos na Constitui??o Federal de 1988 e o modelo gerencial, bem como sobre gest?o de processos e produ??o enxuta. Optou-se pela abordagem qualitativa, sendo a pesquisa um recorte de um Projeto maior que est? em execu??o na referida Coordena??o, cuja finalidade ? melhorar os processos de tramita??o de projetos acad?micos. Para coleta de dados, fez-se uso de grupo focal para identificar os desperd?cios do processo na percep??o dos usu?rios, workshop sobre processos, para construir o fluxo e observa??o participante durante a reuni?o de an?lise do processo juntamente com a equipe de trabalho. A an?lise dos dados qualitativos ocorreu ap?s as transcri??es dos ?udios do grupo focal e da reuni?o de an?lise de processos. Foi realizada atrav?s de conte?do categorial, com o aux?lio do software NVivo?. Os principais resultados encontrados foram: o desperd?cio Espera e o Princ?pio da Efici?ncia, al?m de serem os mais incidentes no fluxo, possuem uma rela??o direta entre si, sendo que a espera tamb?m tem origem nas exig?ncias legais do processo, em atendimento ao Princ?pio da Legalidade. Contudo, observou-se que pode ser reduzida. Verificou-se que o Princ?pio da Legalidade ? um fator limitador para interven??o no fluxo e, nesse contexto, o desperd?cio gerado por Excesso de Processamento, que provoca Espera, Movimento Desnecess?rio e Transporte, torna-se necess?rio para atender ao referido Princ?pio. Constatou-se que h? necessidade de integra??o e outras melhorias nos sistemas para melhorar a efici?ncia do processo. Al?m disso, identificou-se que as etapas Cadastramento e Setor de Minutas s?o as que concentram o maior n?mero de problemas no fluxo e as constantes altera??es nos entendimentos legais foram citadas por todos os sujeitos da pesquisa, demonstrando que se trata de um ponto cr?tico a ser trabalhado pela gest?o. Assim, constatou-se que o grande desafio das institui??es p?blicas ? conciliar suas caracter?sticas e normas ? maior efici?ncia nos servi?os prestados. Espera-se que os resultados obtidos possam direcionar as a??es de melhorias dos processos de tramita??o de projetos acad?micos para cumprimento dos Princ?pios da Administra??o P?blica, bem como auxiliar no desenvolvimento de outros trabalhos acad?micos. / This work aims to analyze the waste in the flow of the process related to the processing of academic projects, in the Coordination of Agreements and Contracts of the Pro-Rectory of Planning and General Coordination of the Federal University of Rio Grande do Norte, in light of the principles of Administration Public, expressed in the caput of Art. 37 of the Federal Constitution of 1988, and of the Lean Production. Considering the context of the research and because it is a public institution, the bibliographic review was done on Public Administration, emphasizing the basic principles expressed in the Federal Constitution of 1988 and the managerial model, as well as on the process management and on the lean production. The qualitative approach and the action research method were chosen, with the research being a cut-off of a larger Project that is being implemented in the said Coordination, whose purpose is to improve the processes of processing academic projects. For data collection, a process workshop and a focus group were used to identify the waste of the process in the client's perception, to build the flow and the participant observation during the process analysis meeting together with the work team. The analysis of the qualitative data occurred after the transcriptions of the audios of the focal group and the meeting of process analysis. It was done through categorical content, with the aid of NVivo? software. The main results were: the Waste of Waiting and the Efficiency Principle, besides being the most incidents in the flow, have a direct relationship between them, being that the wait also originates in the legal requirements of the process, in compliance with the Legality Principle. However, it has been observed that it can be reduced. It has been found that the Legality Principle is a limiting factor for intervention in the flow and, in this context, the waste generated by Excess Processing, which causes Waiting, Unnecessary Motion and Transporting, becomes necessary to comply with the aforesaid Principle. It was found that there is a need for integration and other improvements in the systems to improve the process efficiency. In addition, it was identified that the stages of Registration and Contract Sector are those that concentrate the greatest number of problems in the flow and the constant changes in legal understandings were cited by all the subjects of the research, demonstrating that this is a critical point to management. Thus, it was verified that the great challenge of the public institutions is to reconcile their characteristics and norms to a greater efficiency in the services provided. It is hoped that the results obtained will lead the actions of improvements in the processes of academic projects to comply with the principles of Public Administration, expressed in the Federal Constitution of 1988, as well as to assist in the development of other academic works.

However, alarms and events are often confused and improperly configured similarly by developers of automation systems. This practice results in a high amount of pseudo-alarms during the operation of industrial processes. The high number of alarms is a major obstacle to improving operational efficiency, making it difficult to identify problems and increasing the time to respond to abnormalities. The main consequences of this scenario are the increased risk to personal safety, facilities, environment deterioration and loss of production. The aim of this paper is to present a philosophy for setting up a system of supervision and control, developed with the aim of reducing the amount of pseudo-alarms and increase reliability of the information that the system provides. A real case study was conducted in the automation system of the offshore production of hydrocarbons from Petrobras in Rio Grande do Norte, in order to validate the application of this new methodology. The work followed the premises of the tool presented in ISA SP18.2. 2009, called "life cycle alarm . After the implementation of methodology there was a significant reduction in the number of alarms / No contexto de opera??o de processos industriais, alarme, por defini??o, ? um aviso ao T?cnico de Opera??o que uma a??o com tempo restrito para ser executada ? necess?ria, enquanto que evento ? uma informa??o de mudan?a de estado e n?o demanda a??o por parte do T?cnico de Opera??o, consequentemente n?o deve ser anunciada, sendo apenas armazenada para fins de an?lise de manuten??o, incidentes e utilizadas para sinaliza??o/monitora??o (EEMUA, 2007). Por?m, alarmes e eventos s?o frequentemente confundidos e configurados inadequadamente de forma semelhante por programadores de sistemas de automa??o. Esta pr?tica resulta em uma elevada quantidade de pseudo-alarmes durante a opera??o de processos industriais. O elevado n?mero de alarmes configurados ? um dos principais entraves para a melhoria da efici?ncia operacional, dificultando a identifica??o de problemas e aumentando o tempo de resposta ?s anormalidades. As principais conseq??ncias desse quadro s?o o aumento do risco ? seguran?a das pessoas, instala??es, meio ambiente e o agravamento das perdas de produ??o. O objetivo principal deste trabalho ? apresentar uma filosofia de configura??o de um sistema de supervis?o e controle, desenvolvida com o intuito de diminuir a quantidade de pseudo-alarmes configurados e aumentar a confiabilidade das informa??es que o sistema fornece. Um estudo de caso foi realizado no sistema de automa??o das plataformas mar?timas de produ??o de Hidrocarbonetos da Petrobras no Rio Grande do Norte, de forma a validar a aplica??o dessa nova metodologia. O trabalho seguiu as premissas da ferramenta apresentada na norma ISA SP18.2. 2009, denominado ciclo de vida de alarme . Ap?s a implanta??o da metodologia verificou-se uma redu??o significativa no n?mero de alarmes

O objetivo deste estudo ? compreender a produ??o noticiosa dos blogs do interior potiguar que, em muitas comunidades (PAIVA, 2012), s?o os ?nicos ve?culos de comunica??o que informam sobre o cotidiano local. Descrevemos e analisamos os elementos constituintes e os par?metros de produ??o e de repercuss?o a fim de refletir sobre os efeitos do jornalismo enquanto pr?tica social (GOMES, 2004; PERUZZO, 2005) que comunica o cotidiano. Valendo-nos dos m?todos e t?cnicas do estudo de casos elencamos o Blog do Cl?sio Dantas (Bod?), o Blog do Edmilson Sousa (Currais Novos) e o Blog do Marcos Dantas (Caic?). Para se chegar a essa amostra foi feita uma cartografia das m?dias do Rio Grande do Norte que apontou a aus?ncia dos ve?culos de comunica??o convencionais com abrang?ncia estadual na regi?o central do estado, visto que as emissoras de TV aberta e os grandes jornais localizam-se em Natal e Mossor? e acabam cobrindo, predominantemente, o entorno desses munic?pios. A an?lise envolveu a cataloga??o das publica??es dos blogs e a observa??o das rotinas de produ??o desse jornalismo e a import?ncia desses blogs enquanto meios de informa??o da realidade local. Apresentamos como a tecnologia e a comunica??o em rede t?m transformado o fazer jornal?stico e a participa??o de todos na produ??o de conte?do tem elaborado uma nova l?gica da produ??o informativa (CASTELLS, 2012; DALMONTE, 2009; PAL?CIOS, 2003). Observamos como os blogueiros t?m se preparado para trabalhar com as perspectivas da cultura digital (LEMOS 2103; LEVY, 2000) sob as quais a produ??o jornal?stica agora pulsa em tempo real, em um ritmo fren?tico e ininterrupto (MORETZSOHN, 2002). O estudo possibilitou reunir um conjunto de informa??es detalhadas sobre a blogosfera potiguar e, mais especificamente, sobre os casos analisados, o que viabilizou compreender sobre os in?meros vieses desse fen?meno e de suas implica??es para a sociedade. / Blogs have been set up and now appear as major media, journalism is no longer an exclusively professional activity and now features as a language adopted by people of various profiles to communicate about daily life (CHAPARRO, 2014; SODR?, 2009). The aim of this study is to understand the news production blogs potiguar interior that, in many communities (PAIVA, 2012), are the only means of communication to inform about the place everyday. We describe and analyze the elements and the production and impact parameters to reflect on the effects of journalism as a social practice (GOMES, 2004; PERUZZO, 2005) that communicates daily. Drawing on the methods and techniques of case studies we list the Cl?sio Dantas Blog's (Bod?), the Edmilson Sousa Blog's (Currais Novos) and Marcos Dantas Blog's (Caic?). To achieve this sample was a map of Rio Grande do Norte the media that pointed out the absence of conventional means of communication with statewide in the central region of the state, since the broadcast television stations and major newspapers are located in Natal and Mossor? and end up covering predominantly the surroundings of these cities. The analysis involves cataloging the publications of blogs and the observation of this journalism production routines and the importance of these blogs as of the local reality information means. Here is how technology and network communication have transformed the journalistic making and the participation of all in the production of content have developed a new logic of information production (CASTELLS, 2012; DALMONTE, 2009; PAL?CIOS, 2003). We observe how bloggers have been prepared to work with the prospects of digital culture (LEMOS 2103; LEVY, 2000) under which the journalistic production now pulsates in real time at a frantic pace and uninterrupted (MORETZSOHN, 2002). The study made it possible to assemble a set of detailed information on the potiguar blogosphere and more specifically on the cases analyzed, which enabled understanding about the numerous biases of this phenomenon and its implications for society.

Para o eletrodo dopado com 1 mM do ?on Fe3+, a efici?ncia de corrente da PEO foram de 10% e 9,5% com uma velocidade de gera??o de oz?nio de 1,35 g h-1 e 1,40 g h-1 para os substratos de tela de a?o e de tecido de carbono, respectivamente. Os resultados encontrados s?o promissores indicando uma viabilidade do uso desses eletrodos para aplica??o no tratamento de ?gua, por isso, empregou-se o oz?nio produzido eletroquimicamente para tratar ?gua residu?ria proveniente da produ??o de biodiesel na planta piloto da UFVJM. O tratamento oxidativo da ?gua residu?ria foi conduzido num reator em coluna de bolhas via rea??o direta (oz?nio molecular), indireta (radical hidroxila) e mista (O3/HO?) manipulando-se o pH do meio reacional.A caracteriza??o do efluente ozonizado foi efetuada monitorando-se o processo de degrada??o da mat?ria org?nica dissolvida via espectrofotometria. A cin?tica do processo de degrada??o seguiu o modelo de pseudo-primeira ordem. Foi verificado que a constante cin?tica sofre varia??o com o tempo de ozoniza??o revelando, portanto, uma varia??o da recalcitr?ncia com o tempo de rea??o. A demanda de energia requerida no processo de ozoniza??o foi caracterizada por uma energia el?trica por ordem (EEO) de 139 kW h m-3 ordem-1. / Disserta??o (Mestrado) ?

The analysis of SEM micrographs revealed that for both substrates at low dopants concentrations resulted in the formation of well-defined grains with a uniform surface area. X-rays analysis for both substrates showed the inhibition of formation of the ?-PbO2 phase for most of the dopant concentration. Cronopotenciometric studies revealed a good stability of the anodes when they were subjected to the intense gas evolution. For the electrode doped with 1 mM Fe3+, the current efficiency of EOP were 10% and 9.5% for an ozone generation rate of 1.35 g h-1 and 1.40 g h -1 using the steel screen and carbon cloth substrates, respectively. These results are promising, indicating a feasibility of using these electrodes for application in water purification, so the electrochemical ozone produced was applied to treat residuary water obtained from the biodiesel produced in the pilot plant of UFVJM. The oxidative chemical treatment of wastewater was conducted in a bubble column reactor via direct (molecular ozone), indirect (hydroxyl radical) and mixed (O3/HO?) oxidation reaction thrush manipulating the pH of the reaction medium. The characterization of ozonated effluent was assessed by means of monitoring the degradation of the dissolved organic matter using spectrophotometry. The kinetics of the degradation process followed a pseudo-first order model. It was found that the rate constant changes on the ozonation time thus indicating a recalcitrance variation with the reaction time. The energy demand required in the ozonation process was described by an electric energy per order (EEO) of 139 kW h m-3 order-1.

Nesse contexto, ? importante considerar que embora tenha import?ncia social e econ?mica para o Brasil, nos ?ltimos anos, a suinocultura vem sofrendo severas cr?ticas em virtude da polui??o, sobretudo h?drica, constatada nas regi?es de maior concentra??o animal, colocando sob questionamento o modelo produtivo atualmente adotado. Contudo, observa-se interesse crescente pela ado??o de sistemas alternativos de cria??o de su?nos, entre eles, a cria??o em cama sobreposta que reduz os riscos de contamina??o ambiental pela convers?o do manejo dos dejetos da fase l?quida para a s?lida, al?m da possibilidade de utiliza??o do material org?nico resultante dessa pr?tica como fertilizante.

In this context, it?s important to consider that although has great social and economical relevance for Brazil, in recent years, the swine production industry has been severely criticized due to pollution, mainly in water, that has been noticed in regions where swine production is concentrated. This fact puts in question the current production model. But there is a growing interest in adopting the deep-litter production system, which reduces the risk of environmental contamination by converting the waste handling of the liquid to solid, beyond the possibility of use of organic material resulting from this practice as fertilizer. The objectives of this study were: (a) evaluating performing the physical and chemical characterization of deep-litter for use as an organic fertilizer, taking into account the current legislation for organic compounds and; (b) evaluate the effects of application on physical and chemical properties of a Typic Quartzipsamment, and on nutrient accumulation and dry matter yield of maize plants. By the results obtained, we can conclude: (1) there is a need for additional composting, without the presence of animals, previous to the deep-litter be used as organic fertilizer; (2) the parameters of deep-litter evaluated, in this study, fall within the Brazilian legislation as simple organic fertilizers; (3) although, has provided increases in dry matter of maize, the effects of organic manure with deep-litter were much more pronounced in providing improvements in physical and chemical properties of soil to provide nutrients such as corn and; (4) the information about the use of deep-litter as fertilizer are scarce and; (5) an interesting aspect to assess in future studies, involving mainly the nitrogen mineralization of different types of deep-litter and your residence times in the swine production, in order to be able to establish the potencial fertilizer this compound and to recommend doses of fertilizer to crops.

The work was carried out at the Vegetable and Dietetic Techniques Laboratory and Biomass Technology of Cerrado of Campus JK - UFVJM in Diamantina-MG. We evaluated the total yield of roots and commercial yield of roots, average weight of commercial roots, shape of roots, soil resistance to insects, dry matter content of roots and total carotenoids. Besides these characteristics there were also evaluated the physical and sensorial characteristics: the squash color, texture and softness, sweetness of the squash, cooking time and acceptability of sweet potato clones in the roots. In the aim to study the potential use of these clones in animal feed there were evaluated the yield of green matter, dry matter content and yield of dry mass of branches. The silage of the branches was evaluated for dry matter, crude protein, ADF, NDF, TDN, pH, Phosphorus, Calcium and Sodium. The experiment was conducted in a randomized block design (RBD), including 12 clones and 4 replications. The plots consisted of one row 4.5 m long, using the 1.0 m spacement between rows by 0.30 m between plants, totaling 15 plants per plot. For the sensorial analysis were used 40 untrained tasters for each clone. The clones are part of the germplasm bank of UFVJM, as follows: BD-06, BD-25 BD-15 BD-38, Batiste, BD-TO-31, BD-67 BD-45 BD-42, BD-54 and Pink and White Brazlandia. There were observed significant differences between the clones for the characteristics of commercial yield, resistance to insects, dry matter content and total carotenoids in roots of sweet potato clones. The evaluated clones showed similar characteristics of yield when compared to commercial cultivars Pink and White Brazlandia. The clones BD-25 BD-54 BD-31-TO and Batiste scored in evaluation for resistance to insects of soil below 2.0 and were considered resistant to soil insects. Clones BD-54 BD-31-TO, Batiste and BD-45 had high dry matter content in roots. The highest content of carotenoids in roots was obtained by clone BD-67. Clones BD-06, BD-38, Batiste, BD-TO-31, BD-67 BD-42 BD-54 and Pink and White Brazlandia had a level of acceptability above 70%, being accepted by consumers. The clones showed productivity of green mass and dry mass of branches similar to Pink and White Brazlandia commercial cultivars. There was no difference in yield of green mass and dry weight of branches among the clones of sweet potato. There were no differences between the clones on the crude protein content of silage forms. The branches of sweet potatoes in the majority of the clones showed potencial use for animal feed, either as fresh as in the form of silage.

Therefore, the objective of this study was to characterize the physical and chemical parameters of pig slurry (DLS), treated in a system of ponds in series and evaluate the changes in the microbial soil of a coffee plantation after applying different doses of pig slurry. The study was conducted in the Campo Alegre Farm and Ranch Yamaguchi in the city of Diamantina, Minas Gerais. The DLS were collected at various points: exit of the facilities, exit of the anaerobic pond, exit of the first facultative pond, exit of the second facultative pond, and analyzed: Chemical Oxygen Demand (DQOt), Biochemical Oxygen Demand (BOD5) concentration Total Solids (DS), Total Nitrogen (Total-N), Phosphorus, Potassium, Zinc, and Copper. After analysis, the pig manure were applied in a coffee plantation, in an experiment consisting of five treatments with five replications. Soil samples were collected at 0-10 cm depth. It was evaluated the basal respiration, microbial biomass carbon and metabolic quotient determined. The results show that the system of stabilization ponds in series features 88% efficiency in removing DQOt and 91% for BOD5 removal. The fractions of solids showed similar behavior and t removal efficiency of Total-N accounted for 24.2%. Use of pig slurry in soil, before and 30 days after application, amplified the soil microbial biomass and microbial activity. The results showed that the system of stabilization ponds in series proves to be effective in removing excess nutrients. It is noteworthy that treatment showed favorable characteristics for reuse of wastes as biofertilizers.
