In this context, the development and application of arbuscular mycorrhizal fungi (AMF) (Phylum Glomeromycota) inoculants represents a promising alternative for increasing the utilization eficiency of chemical fertilizers, mainly the phosphates In the present work a survey of the AMF community was carried out before planting and after harvesting of the "plant cane" in renewal (rotated or not with Brachiaria ruziziensis) and expansion (previously under pasture) areas. A similar assessment was carried out in sugarcane renovation and expansion areas where two experiments of inoculation with diazotrophic bacterias were being conducted. Under greenhouse conditions, two experiments for selecting AMF strains for sugarcane (Variety SP81-3250) in different soils and substrates were carried out. In renewal areas, after maintained sugarcane monocropping, a rotation cycle with B. ruziziensis between the ratoon removal and the new cane planting doesnot influence the AMF species richness. Prolonged monoculture of sugarcane tends to reduce the AMF diversity after the renewal of the sugarcane plantation, but stills quite high compared to other agricultural systems. In pasture areas converted to sugarcane plantation (expansion) the AMF species richness tends to be higher in the first year after the conversion (plant cane) compared to sugarcane renovation areas. The spore density reached the highest values after the "plant cane" harvesting. The AMF isolates with potentiality to compose a mycorrhizal inoculant for sugarcane areAcaulospora colombiana and Claroideoglomus etunicatum which favoured the development of the pre-sprouted seedlings of sugarcane in soil and substrate. Other isolates that promoted the sugarcane seedlings' development ou nutrition, but still need additional studies are Gigaspora margarita, Scutellospora calospora and Rhizophagus clarus. The expansion area soil (with moderate P content) was the most favorable for the sugarcane growth. The Multiplant substrate promoted the highest growth of the seedlings and favored the AMF colonization. The fertillization recommended for sugarcane seedling production inhibited the plants growth, particularly in the substrate Turfa F?rtil. The Sugar Mill substrate stimulated the seedlings growth the least. The rate of dark septate endophytes colonization (DSE) in the sugarcane seedlings of the cultivar SP81-3250 was high, independently of the inoculated AMF isolate. All the AMF isolates tested showed simultaneus colonization with DSE. / O Brasil ? o maior produtor mundial de cana-de-a??car, sendo a cultura respons?vel por 15% dos fertilizantes utilizados no pa?s. Nesse contexto, o desenvolvimento e aplica??o de inoculantes de fungos micorr?zicos arbusculares (FMAs) (Phylum Glomeromycota) representa uma promissora alternativa para incrementara efici?ncia de aproveitamento dos fertilizantes, principalmente os sfatados. No presente trabalho foi realizado um levantamento da comunidade de FMAs pr?-plantio e p?s-colheita da "cana planta" em ?reas de renova??o (rotacionadas ou n?o com Brachiaria ruzizensis) e expans?o (previamente sobre pastagem) do canavial. Uma avalia??o similar foi realizada em ?reas correspondentes a dois experimentos de inocula??o com bact?rias diazotr?ficas. Foram conduzidos, em casa de vegeta??o, dois experimentos de sele??o de linhagens de FMAs para cana-de-a??car (Cultivar SP81-3250) em diferentes solos e substratos. Em ?reas de monocultivo prolongado de cana-de-a??car uma rota??o com B. ruziziensis na ?poca da renova??o n?o influencia a riqueza da comunidade de FMAs. Por?m, a riqueza de FMAs diminui em monocultura prolongada de cana, mas ainda ? elevada comparada com outros sistemas agr?colas. A riqueza de FMAs em pastagem convertida a canavial ? maior na ?cana planta? comparada ? ?reas de renova??o de canavial. As maiores densidades de esporos nas ?reas canavieiras ocorrem ap?s a colheita da ?cana planta?. As linhagens de FMAs com potencialidade para compor um inoculante micorr?zico para cana-de-a??car s?o Acaulospora colombiana Claroideoglomus etunicatum as quais favorecem o desenvolvimento de mudas pr?-brotadas de cana tanto em solo como em substrato. Outras linhagens que precisam de estudos adicionais por promoverem crescimento ou nutri??o de mudas de cana s?o Gigaspora margarita, Scutellospora calospora e Rhizophagus clarus. O solo da ?rea de expans?o, com teores intermedi?rios de P, ? o mais favor?vel para o crescimento da cana-de-a??car. O substrato Multiplant foi o que mais estimulou o crescimento de mudas pr?-brotadas e promove a maior coloniza??o por FMAs. A aduba??o completa recomendada para a produ??o de mudas pr?-brotadas de cana-de-a??car inibiu o crescimento das plantas, particularmente no substrato Turfa F?rtil. O substrato da Usina promoveu o menor crescimento de mudas de cana-de-a??car. A taxa de coloniza??o radicular por DSE nas mudas da cultivar SP81-3250 foi elevada, independentemente da linhagem de FMA inoculada. Todas as linhagens de FMAs avaliadas apresentaram coloniza??o conjunta com DSE.

Formed as a scientific field in the 1980s, ecological restoration proposed a new type of engagement with biodiversity which differed considerably from the strategies taken by preservationism and conservationism in the last century. More than protecting or conserving, the practice of ecological restoration seeks to create ecosystems. Numerous controversies on how it is possible to create new ecosystems will involve ecological restoration?s specialists. Starting from a dialogue with sociology and anthropology of science, the thesis explores the formation process of this field and aims to highlight what horizons of action are constituted by the ecological restoration?s practices. The work was done following three main lines. First it analyses two specialized journals editorials - written between 1981 and 2016 - to identify the most problematic issues defined by the scientists. Later the thesis explores the configuration of the field in Brazil and, finally, it discusses the relations between ecological restoration, ruralities and agriculture in Brazil. The aim is to circumscribe the emergence of different forms of ecological restoration. We will show that the theory and practice of this field of study are indissolubly linked to three aspects: the type of science which is considered by scientists able to define actions; the definition of a reference system that should guide scientists in the creation process of ecosystems and the different understanding of human-nonhuman relations. Ecological restoration works by projecting potential relationships among a multiplicity of agents. In this work ecological restoration will be considered as an (eco) political technology which involves the creation and modulation of socio-ecological relations and not only ecologica / O objetivo desta tese foi analisar a teoria e a pr?tica da restaura??o ecol?gica. Formada como campo cient?fico na d?cada de 1980 a restaura??o ecol?gica prop?s um novo tipo de compromisso com a biodiversidade que se diferenciava muito das estrat?gias assumidas pelo preservacionismo e conservacionismo no s?culo passado. Mais do que proteger ou conservar, a pr?tica de restaura??o ecol?gica busca criar ecossistemas. In?meras controv?rsias envolver?o os especialistas da ?rea a respeito de como isso pode ou deve ser feito. Essa tese ir? acompanhar o processo de forma??o desse campo buscando ressaltar, a partir dos instrumentos te?ricos vindo da sociologia e antropologia da ci?ncia, quais horizontes de a??o s?o constitu?dos pela pr?tica. O trabalho foi realizado a partir de tr?s linhas principais: an?lise dos editoriais de duas revistas especializadas na ?rea entre os anos de 1981 e 2016, para identificar o campo problem?tico dos cientistas; an?lise da forma??o do campo no Brasil e, por fim, a discuss?o sobre as rela??es entre restaura??o ecol?gica, ruralidades e agriculturas no Brasil. O objetivo foi delimitar a emerg?ncia de diferentes formas de restaura??o ecol?gica. Veremos que a teoria e a pr?tica do campo est?o indissoluvelmente ligadas a tr?s aspectos: ao tipo de ci?ncia considerada apta pelos cientistas para definir as a??es; ? defini??o de um sistema de refer?ncia que deve orientar os cientistas na cria??o dos ecossistemas e ao modo como ser?o definidas as rela??es entre humanos e n?o-humanos.

The soil classification is the basis for determining the potential use of the land, ie, guide the sustainable use of the same. For this situation, it is known that many factors corroborate the frame. Among these the human factor has great weight in this matter because, Survey and Soil Classification (LCSs) are present on curricular content for training of Agronomists, Forestry Engineers, etc.., and scholars and authorities in the field of Soil Science have signaled that the Higher Education Institutions (specifically undergraduate) come crashing in training these professionals supposedly trained and qualified to the activity of LCSs, considering that the courses that form such professionals invariably advocated among other things "solid scientific general and professional ... "what prescribes the contents of their curricular chord in the National Curriculum Guidelines. Informally today, teachers generally do mind that the problem lies in the structure of undergraduate courses regarding aspects: design of a workload of disciplines; literature indicated in ement?rios; disciplines sequence prerequisites; opportunity of additional knowledge through elective courses, etc.. Thus, sensing data bring to literature that deal with the subject, aimed this work was to analyze the conditions for teaching of LCSs course of Forestry's IFMT - Campus C?ceres through its Political-Pedagogical Project (PPP) as all the above aspects. This research is exploratory, Documentary and Quanti-qualitative nature. Included in the questionnaire data collection and content analysis for inferences. The inferences are that the references (data obtained from educators in the field of Soil Science of the five geographical regions through a questionnaire) indicate that the PPP course has limitations that may affect the teaching-learning LCSs and achieve, in this regard (themes mentioned), the professional profile designed by the course concerning "solid scientific and professional general enabling absorb and develop technology." The limitations were: inadequate sizing workload in disciplines that include LCSs and related activities; literature indicated in these ement?rio not include modern features with the potential to collaborate with a better education, sequence of disciplines inappropriate prerequisites discipline that includes these activities and, lack of opportunity for complementation of knowledge related to these themes via list of electives. Given the paucity of information in the literature that addresses on the subject, the data generated will assist both in the construction and / or reformulation of PPP courses in general as well as instigating research on the topic. / Apesar de toda produ??o agropecu?ria que saem dos solos brasileiros, pujan?a do agroneg?cio que se noticia, a maior parte dos solos do Pa?s n?o est?o classificados a n?vel adequado para utiliza??o do agricultor; ou melhor, dizendo, as propriedades agr?colas e florestais, em sua maioria, n?o possuem um mapeamento de seus solos, logo, majoritariamente produtores e profissionais tecnicamente atuantes nestas propriedades n?o possuem um conhecimento detalhado dos tipos de solos que se t?m trabalhado. A classifica??o dos solos serve de base para determina??o do potencial de uso das terras, ou seja, norteiam a utiliza??o sustent?vel das mesmas. Para esta situa??o, sabe-se que muitos fatores corroboram com o quadro. Dentre estes o fator humano tem grande peso nesta quest?o; pois, Levantamento e Classifica??o de Solos (LCSs) s?o conte?dos presentes nas matrizes curriculares para forma??o de Engenheiros Agr?nomos, Engenheiros Florestais, etc.; e, estudiosos e autoridades da ?rea de Ci?ncia do Solo t?m sinalizado que as Institui??es de Ensino Superior (especificamente cursos de gradua??o) v?m falhando na forma??o desses profissionais pressupostamente capacitados e habilitados para a atividade de LCSs; tendo em vista que, os cursos que formam tais profissionais, invariavelmente, preconizam dentre outras coisas ?s?lida forma??o cientifica e profissional geral...? daquilo que prescreve os conte?dos de suas matrizes curriculares em acorde com as Diretrizes Curriculares Nacionais. Informalmente na atualidade, docentes em geral cogitam que o problema est? na estrutura dos cursos de gradua??o quanto aos aspectos: dimensionamento de carga hor?ria de disciplinas; bibliografia indicada em ement?rios; sequencia de disciplinas pr?-requisitos; oportunidade de complementa??o de conhecimentos via disciplinas optativas, etc. Dessa forma, intuindo trazer dados ? literatura que versem sobre o assunto, objetivou-se com este trabalho analisar as condi??es para atividades de ensino de LCSs do curso de Engenharia Florestal do IFMT - Campus C?ceres atrav?s de seu Projeto Pol?tico-Pedag?gico (PPP) quanto aos aspectos supramencionados. A presente pesquisa ? Explorat?ria, Documental e de natureza Quanti-qualitativa. Incluiu o Question?rio na coleta dos dados e a An?lise de Conte?do para as infer?ncias. As infer?ncias s?o de que as refer?ncias (dados obtidos junto a educadores da ?rea de Ci?ncia do Solo das cinco regi?es geogr?ficas brasileiras atrav?s de question?rio) indicam que o PPP do curso apresenta limita??es que podem comprometer o ensino-aprendizado de LCSs e alcan?ar, neste quesito (tem?ticas mencionadas), o perfil profissional projetado pelo curso concernente a ?s?lida forma??o cient?fica e profissional geral que possibilite absorver e desenvolver tecnologia?. As limita??es encontradas foram: dimensionamento inadequado de carga hor?ria em disciplinas que contemplam LCSs e atividades correlatas; bibliografia indicada no ement?rio destas n?o incluem recursos modernos com potencial de colaborar com uma melhor forma??o; sequ?ncia inapropriada de disciplinas pr?-requisitos a disciplina que contempla estas atividades; e, inexist?ncia de oportunidade para complementa??o dos conhecimentos relacionados a tais tem?ticas via rol de disciplinas optativas. Dado a escassez de informa??es na literatura que trate sobre o assunto, os dados gerados poder?o auxiliar tanto na constru??o e/ou reformula??o de PPP de cursos em geral bem como instigar pesquisas sobre a tem?tica.

In the first chapter, a literature review, the results of research with sugarcane and changes in biological, chemical and physical soil properties, in response to trash management and their relationship with soil quality, are presented. In general, the data suggest that harvesting without burning affects positively the soil properties and improves soil quality. However, the studies are not sufficient to inform about the effect of mechanical harvesting without burning of trash in the tableland soils. In the second chapter they were evaluated the effect of N fertilization of green sugarcane on the stalk productivity, the trash accumulation, the relationship between the number and weight of stalks, the extraction and accumulation of nutrients in the fresh stalks and trash, and the sugarcane technological quality. This study was conducted in the LASA distillery, in Linhares municipality, Esp?rito Santo State, with ratoon cane, varieties RB86 7515 and RB91 8639, in a Xanthic Udult soil. The experiment was set in a randomized blocks design with the control (without N) and four treatments with N applied as ammonium sulphate (80, 100, 120, and 160 kg N ha-1) in four replicates. The N had a significant effect on stalks productivity. The relationship between the number and weight of stalks was significant for the dosages of 80 kg N ha-1 (both varieties) and 100 kg N ha-1 (only the RB91 8639 variety). There was significant effect of N rates on the cane technological quality only in the second cycle studied. The extractions of N, P and K were significant for the N levels. The third chapter is a simulation study conducted with the APSIM-Sugar cropping systems model, based on data from the log-term experiment (duration of 23 years) in the municipaliy of Linhares-ES. This study had as goal to investigate the impact of trash management after harvesting on sugarcane production and the long-term fate of N contained in trash. The objectives were: to investigate if the model was capable of reproducing the trends of the major N pools (cane yields and soil organic carbon) in the long term experiment; and using the parameterized model to evaluate how the relationship between N fertilizer and yield (and losses of N to the environment) varies with the trash management. The trash management systems conditions simulated were: retention of trash at harvest (100 %, GCTB); half retention of trash at harvest (50%); and burnt cane trash. The N fertilizer management system was simulated by varying N fertilizer application from 0 to 240 kg ha-1 (in 40 kg ha-1 increments) rates on the ratoon crops. The cane yield and soil organic C responded positively to the trash management systems (GCTB and half GCTB), but the magnitude of the response is dependent on N-fertilizer applied on crops. Half removal of trash might reduce the extent of yield increasing potential. When the trash deposition is a recent practice, additional N fertilizer is required by the crop, to avoid yield reduction caused by the N immobilization. The simulations also indicated that the average environmental losses of N were greater from trash retained systems for all rates on N fertilizer applied. / Para avaliar o impacto do manejo da palhada sobre a qualidade do solo e produ??o de cana-de-a??car na regi?o dos Tabuleiros Costeiros, tr?s estudos foram conduzidos e s?o apresentados em cap?tulos. No primeiro cap?tulo, em forma de revis?o de literatura s?o apresentados os resultados de pesquisas com cana-de-a??car e altera??es nas propriedades biol?gicas, qu?micas e f?sicas do solo em resposta ao manejo da palha, e sua rela??o com a qualidade do solo. Do conjunto de dados, se infere que a colheita sem queima com manuten??o da palha altera positivamente as propriedades ed?ficas e melhora a qualidade do solo. Por?m, os estudos s?o insuficientes para suprir informa??es sobre o efeito da colheita mec?nica e sem queima da palhada da cana sobre os solos de tabuleiro. No segundo cap?tulo foram avaliados, os efeitos da aduba??o nitrogenada, em cana crua, sobre a produtividade de colmos, ac?mulo de palhada, rela??o entre n?mero e peso colmo, extra??o e ac?mulo de nutrientes nos colmos frecos e na palhada, e sobre a qualidade tecnol?gica da cana de a??car. O estudo foi realizado na destilaria LASA no munic?pio de Linhares-ES, com cana soca, variedades RB 867515 e RB 918639, em ARGISSOLO AMARELO. Os tratamentos consistiram de cinco doses de N-Sulfato de am?nio (sem N, 80, 100, 120 e 160 kg de N ha-1), arranjados em desenho experimental de blocos casualizados com quatro repeti??es. Houve efeito significativo de doses de N sobre produtividade de colmos. A associa??o entre n?mero e peso de colmos foi significativa para 80 kg N ha-1 (ambas as variedades) e 100 kg ha-1 (para a variedade RB91 8639). Houve efeito significativo das doses de N sobre a qualidade tecnol?gica da cana apenas no segundo ciclo de cultivo estudado. As extra??es dos nutrientes N, P e K mostraram signific?ncia para as doses de N. O terceiro cap?tulo, relata um estudo de simula??o conduzido com o APSM-Sugar cropping systems model, com dados de um experimento de campo de longa dura??o (cerca de 23 anos) em Linhares-ES. Este estudo se prop?s a investigar o impacto do manejo da palhada ap?s a colheita sobre a produtividade da cana e o destino em longo prazo do N contido na palha. Os objetivos foram: investigar se o modelo foi capaz de reproduzir as tend?ncias de maiores ?pools? de N (rendimento de cana e C org?nico no solo) no experimento de longa dura??o; e usar o modelo parametrizado para investigar como a rela??o entre o N-fertilizante e rendimento (e perdas de N para o ambiente) varia com o manejo da palhada. As condi??es de manejo da palha simuladas foram: 100% e 50% da palhada retida ap?s a colheita; e palhada queimada. O manejo da aduba??o foi simulado para variar com as doses de N de 0 a 240 kg ha-1 (com incrementos de 40 kg ha-1) em cana soca. O rendimento de cana e o C org?nico do solo foram bem representados pelo modelo. O rendimento de cana respondeu positivamente aos sistemas de manejo da palhada (100% e 50% de reten??o), mas a magnitude da resposta depende da aduba??o nitrogenada. A remo??o de 50% da palha pode reduzir o efeito de rendimento potencial. Quando a deposi??o da palhada ? pr?tica recente, N adicional ? requerido pela cultura para evitar redu??o do rendimento causada pela imobiliza??o do N. As simula??es tamb?m indicam que as perdas ambientais de N foram maiores nos sistemas com cana crua para todas as doses de N.

Dessa forma, possuir uma interface que ofere?a uma boa experi?ncia do usu?rio faz-se necess?rio para a sobreviv?ncia das empresas. Nesse cen?rio, o presente trabalho teve como objetivo investigar a experi?ncia do usu?rio como fator para obsolesc?ncia de software, quais estrat?gias podem ser utilizadas para mitigar esse problema e por fim criar uma ferramenta (FLUX) para suportar as equipes de design de produtos digitais. Para o desenvolvimento do projeto, utilizou-se de pesquisa com usu?rios de softwares. Al?m disso, buscou-se realizar entrevistas com profissionais da ?rea de Design e Tecnologia para valida??o dos conceitos. Acredita-se que a redu??o do tempo de concep??o das solu??es, o aumento do relacionamento com o usu?rio, posicionando-o como co-autor, al?m da adapta??o r?pida e da ado??o do FLUX durante o desenvolvimento de software pode postergar a obsolesc?ncia do software e tamb?m reduzir custos de atendimento, redesign e desenvolvimento. / Software applications are becoming highly critical in developing a business or startup.

In this way, having an interface that offers a good user experience, is a necessity for the survival of companies. By considering this scenario, the present work is aimed to investigate the user experience how factor for software obsolescence and, what strategies could be used to mitigate this problem and finally it will be proposed a tool (FLUX) to support product digitals designers teams. For the development of the project, we carried out research with software users. In addition, we sought to conduct interviews with professionals in the area of Design and Technology to validate the concepts. It is believed that reducing the time to design solutions, increasing the user relationship, positioning it as a co-author, as well as the rapid adaptation and adoption of FLUX during software development may delay software obsolescence and Also reduce costs (service, redesign, and development).

Ainda, a an?lise do cen?rio a partir de di?logos com profissionais da ?rea, identificou que modelos anat?micos sint?ticos por vezes n?o t?m o realismo desejado para determinadas aplica??es. ? dentro desse contexto que se insere o projeto de pesquisa centrado no desenvolvimento de solu??es para capacita??es e diagn?sticos na ?rea da sa?de a partir de processos de prototipagem. Com o objetivo de transbordar a idea??o para o mercado, o projeto foi fundamentado na metodologia do Design Thinking . A fim de entender a rela??o dos indiv?duos com o problema, foram conduzidas entrevistas embasadas no Canvas de Proposta de Valor, e a convers?o do problema em neg?cio fez-se utilizando o Canvas de Modelo de Neg?cios.

Vieria et al (2013) and Marrey Neto (2006) show that a high maintenance cost, the difficulty in obtaining bodies and the risk that conservation materials present to the health of those who come in contact with them in anatomical laboratories constitute obstacles to the study of anatomy through traditional methods. Still, a scenario analysis based on interviews with healthcare professionals, identified that synthetic anatomical models sometimes do not have the realism desired for certain applications. It is within this context that resides the research project centered on the development of solutions for training and diagnostics in the healthcare area from prototyping processes. In order to transform the idea into a business, the project was based on the Design Thinking methodology. In order to understand the relationship of individuals with the problem, interviews were conducted based on the Value Proposition Canvas, and the conversion of the problem into a business was done using the Business Model Canvas. With the purpose of validating the proposals elaborated, three products were developed for evaluation by clients and professionals of the area. From the feedback received, it could be concluded that the proposed products and services have market adherence and represent a potential innovation in the way of teaching, practicing, planning and conducting health procedures.

O trabalho analisar?? as pol??ticas sociais sob a ??gide da justi??a social, com destaque para a dicotomia entre redistribui????o e reconhecimento. Apoiando-se na literatura sobre exclus??o e na proposta de constru????o de um paradigma bidimensional ele apresenta o caso das pol??ticas sociais de Belo Horizonte. Na an??lise deste caso, a partir da pesquisa documental e emp??rica dos programas sociais do munic??pio, toma como refer??ncia a l??gica fuzzy e usa o m??todo Grade of Membership-GoM, para agrupar os diversos programas a partir de sua percep????o de injusti??a social. Ao mostrar a import??ncia da integra????o das perspectivas da redistribui????o e do reconhecimento na formula????o e na implementa????o de pol??ticas sociais adequadas ??s demandas do nosso tempo, o estudo recupera outras dimens??es e categorias importantes na estrutura????o da agenda social, como por exemplo o territ??rio, os grupos sociais, a focaliza????o, a universaliza????o e a intersetorialidade. / In his constant transformation process, the State deals with the inequality problem. This work will analyze the social politics under the protection of social justice, highlithing a dichotomy between redistribution and acknowledgement. Based on literacy about exclusion and on the proposal of a constrution of a bidimentional paradigm, it shows the events of social politics in Belo Horizonte. On the analysis of this events, through documental and empirical research on social programs of the county, it is used as a reference the fuzzy logics and it is utilized the GoM formula to group the many programs trough the perception of social injustice. By showing the importance of integration of the perspectives of redistribution and acknowledgment of formulation and implementation of adequated social politics, this study recovers other dimentions and important categories on estruturation of a social agenda, such as the territory, social groups, universalization, and intersectoriality. / Governo e Pol??tica

He proposes and it applies a synthetic index that it tries to portray important dimensions of the process of incubation of companies of technological base. The work, of exploratory and descriptive nature, uses as research instruments, the bibliographical and documental rising, the exploration of data and statistical information, and the application of the method distancial for standardization of variables. The proposed index, Index of measurement of the process of incubation of companies of technological base - IEBT is composed by four dimensions: Government priority to the public politics of C,T&I, Width and diffusion of the incubation process, Level of technological innovation in the companies, and Level of formal education of the population, and to each dimension it corresponds a group of indicators. IEBT makes possible to order the relative position of the states as for the apprenticeship of development of the process of incubation of companies of technological base, under the dimensions that compose it. The results of IEBT for the states of the areas southeast and south of the country, they suggest that the apprenticeship of development of the process of incubation of companies of technological base comes advanced in the states of S??o Paulo and Rio Grande do Sul, while Rio de Janeiro, Paran?? and Santa Catarina would correspond to an intermediate apprenticeship. Minas Gerais would correspond to a little advanced apprenticeship, just overcoming the Esp??rito Santo (that presented lowest IEBT among the states of the areas southeast and south of Brazil). In what it says respect specifically to Minas Gerais, the results suggest that the main fragilities of the process of incubation of companies of technological base are associated at the dimensions Level of formal education of the population and the Government priority to the public politics of C,T&I. Already the dimension Width and diffusion of the incubation process and the dimension Level of technological innovation in the companies presented potentialities for the development and consolidation of the process of incubation of companies of technological base in the state. / Ci??ncia, Informa????o e Comunica????o
