Knowledge the behavior of plants against environmental resources, such as light, water and mainly the availability of nutrients in the soil, being essential to management in agroecosystems. Field reports suggest the weed species of fast cycle has the characteristics following: well adapted to soils of high fertility and high capacity to accumulate dry matter; which plant matter is quickly decomposed in soil. The objective of this study was to evaluate the effect of increasing of N, P and K doses on growth of Nicandra physaloides as well as the nutrients content, chemical characteristics and C/N ratio of the weed. In the first experiment was evaluated the influence of nutrient levels in accumulation and partitioning of dry matter, height and growth rates of N. physaloides. In the second experiment evaluated the effects of N, P and K doses on content and accumulation of nutrients, chemical characteristics and the C/N ratio of the weed. The specie was highly responsive to fertilization. However, biomass partitioning was not altered by fertilization. When grown on low soils fertility levels, N. physaloides showed low growth rates on low nutrients level. Higher N, P and K contents were observed in plants grown on higher levels of fertilizer. The increasing of N, P and K levels of soil resulted in greater total accumulation of these macronutrients. The treatments did not affect the chemical composition (NDF and ADF) and the C/N ratio of plant. N. physaloides showed lower C/N ratio during experimental period, which combined to low levels of NDF and ADF and great nutrient accumulation, suggests that this plant matter is quickly decomposed, providing a rapid cycling of nutrients.

Piata in soils contaminated by picloram, determining its influence on physiological and vegetative characteristics in beans, used as bioindicator. For this, two experiments were conducted, the first consisting of the application of different doses of the herbicide picloram ( 0 , 7.5, 15 , 30, 60 and 120 g ha - 1 ) which were cultivated Brachiaria Brizantha cv. Piata for a period of 150 days. The second experiment consisted of permanence B. brizantha cv. Piat? on the soil in different periods (150 , 210, 240, 270 to 300 days) after the application of a dose of 240 g ha-1 of picloram. The experimental design for both experiments was a randomized block with five replications. The evaluations were made by measuring the height ( cm ) , dry matter ( g ) and mass of green matter ( g ) of Brachiaria plants in the trial 1 , and dry matter ( g ) of Brachiaria plants for respective periods proposed in the trial 2. For the bean plants, were made evaluations at 50 days after sowing (DAS) of the following variables: plant height ( cm ) , dry matter ( g ) , mass of green matter ( g ) , phytotoxicity ( % ) to 25 and 50 days , leaf area ( cm2 ) , number of leaves per plant , maximum photosynthetic efficiency ( Fv / Fm ) and the relative rate of electron transport (ETR). Evaluating the effects on plants, the phytoremediation, and the bioindicator. It can be concluded that the remediation provided by the cultivation of B. brizantha cv. Piata was effective only when were applied doses below 60 g ha - 1 in the soil. After the application of picloram, the longest period on the soil with brachiaria (300 DAS) provided the greatest potential to remediation and hence improving the physiological and morphological characteristics of the bean.

O estudo foi conduzido em uma ?rea de Reserva Legal pertencente ? empresa Anglo Ferrous Minas-Rio Minera??o S.A no munic?pio de Dom Joaquim (MG), nas coordenadas 19?00'09'' S e 43?11'38'' W e com altitude m?dia de 738m. O fragmento possui aproximadamente 105 ha e encontra-se disposto em encostas com declividades acentuadas, com pequenos cursos d??gua entre as mesmas.Foram observados sinais de impactos naturais causados pela alta intensidade dos ventos, que ocasionam quedas de ?rvores e aberturas do dossel. Para o invent?rio florestal foram alocadas trinta parcelas de 20 ? 20 m (400 m?) totalizando ?rea amostral de 1,2 hectare.Nestas foram amostrados todos os indiv?duos arb?reos com circunfer?ncia ? altura do peito (CAP) > 15,7 cm, exceto lianas e indiv?duos mortos. As esp?cies amostradas foram classificadas em quatro sistemas de guildas (dispers?o, poliniza??o, toler?ncia ? desseca??o e densidade da madeira). Foram mensurados 2056 indiv?duos distribu?dos em 156 esp?cies, 104 g?neros e 46 fam?lias.A distribui??o por classes diam?tricas dos indiv?duos da comunidade arb?rea obteve uma tend?ncia de J-invertido, comportamento esperado para florestas inequi?neas. Por?m, a an?lise para algumas esp?cies isoladas n?o possu?ram esse padr?o, fato este relacionado com a ecologia populacional de cada esp?cie ou com limita??es no recrutamento.Foi verificado um alto valor de H?, o que indica uma ?rea com diversidade relativamente alta e uma fraca domin?ncia ecol?gica de esp?cies verificada tanto pelo elevado valor de J? como pela reduzida porcentagem do somat?rio das dez principais esp?cies para todos par?metros fitossociol?gicos. No fragmento tamb?m foram levantadas esp?cies que est?o inseridas na lista das esp?cies amea?adas de extin??o do IBAMA, sendo estas Euterpe edulis, Zeyheria tuberculosa, Apuleia leiocarpa, Dalbergia nigra, Melanoxylon bra?na, Syagrus macrocarpa, Ocotea odorifera e Almeidea coerulea. Na guilda de dispers?o a ?nica s?ndrome considerada significativa foi a anemoc?rica (indiv?duos foram mais frequente que o esperado nos estratos intermedi?rio e superior), o que ocorreu devido nestes locais haver uma maior a??o do vento e aus?ncia de obst?culos. A s?ndrome de dispers?o zooc?rica, predominou em todos os estratos, por?m estatisticamente n?o houve diferen?as significativas. Este resultado parece estar fortemente relacionado ao habitat dos animais, j? que s?o nessas ?reas que a fauna encontram maior prote??o contra preda??o. Para poliniza??o tamb?m foi constatado uma domin?ncia de indiv?duos polinizados por animais em todos os estratos, por?m tamb?m sem diferen?as significativas. Esse predom?nio sugere a import?ncia do papel da fauna na garantia do fluxo g?nico. J? a guilda toler?ncia a desseca??o apresentou em todos os estratos analisados diferen?as significativas entre as categorias de toler?ncia, onde indiv?duos com sementes recalcitrantes foram mais frequente que o esperado nos estrato inferior e emergente, sugerindo que no fragmento ocorreu algum dist?rbio a m?dio prazo de tempo e que este se encontra em pleno processo de sucess?o secund?ria, j? que h? indiv?duos de sementes recalcitrantes (est?gio sucessional avan?ado) jovens que substituir?o os indiv?duos situados nos estratos superiores. Corroborando com a toler?ncia ? desseca??o, a densidade da madeira apresentou um predom?nio de indiv?duos madeira pesada (est?gio sucessional mais avan?ado) no estrato inferior, evidenciando mais uma vez a substitui??o de indiv?duos de est?gio sucessional intermedi?rio. / Disserta??o (Mestrado) ?

The study was conducted in a Legal Reserve area belonging to the company Anglo Ferrous Minas-Rio Minera??o S.A. in the municipality of Don Joaquim (MG), at coordinates 19? 00'09'' S and 43? 11'38'' W and average altitude of 738 m. The fragment has approximately 105 ha and is arranged on slopes with steep slopes, with small streams between them. Signs of natural impacts caused by the high intensity of the winds, which cause falling trees and canopy openings were observed. For the forest inventory were allocated thirty plots of 20 ? 20 m (400 m?) of the total sampled area of 1.2 hectare. In these, were sampled all the trees with circumference at breast height (CBH) > 15.7 centimeters, except lianas and dead individuals. Sampled species were classified into four guilds systems (dispersal, pollination, desiccation tolerance and wood density). 2056 individuals were measured, distribuite in: 156 species 104 genus and 46 families. The distribution by diameter classes of individuals of the tree community, obteined a trend of inverted-J behavior, expected for uneven aged forest. However, the analysis of some isolated species did not possess this pattern, a fact related to the population ecology of each species or the limitations in recruitment. A high value of H' was found, which indicates an area with relatively high diversity and low ecological dominance of species, verified by the high value of J' and for the small percentage of the sum of the ten major species for all phytosociological parameters. In the fragment were collected species that are also included in the list of endangered species of IBAMA, such as Euterpe edulis, Zeyheria tuberculosa, Apuleia leiocarpa, Dalbergia nigra, Melanoxylon brauna, Syagrus macrocarpa, Ocotea odorifera and Almeidea coerulea. In the dispersion guild, the only syndrome that was considered significant was the anemocoric (individuals were more frequent than expected in the intermediate and superior stratas), which occurred because these sites have a higher wind action and absence of obstacles. The zoochoric dispersion syndrome, predominated in all stratas, but statistically there were no significant differences. This result appears to be strongly related to the habitat of the animals, since these are areas that the fauna found a greater protection against predation. For pollination, have been found the predominance of individuals pollinated by animals in all strata, but also without significant differences. This predominance suggests the importance of the role of fauna in ensuring the gene flow. The guild presented desiccation tolerance in all stratas analyzed significant differences between categories of tolerance, where individuals with recalcitrant seeds were more frequent than expected in emerging and inferior strata, suggesting that in the fragment occured some disturbance in the medium and long term that this is in the process of secondary succession, since there are individuals of young recalcitrant seeds (late successional state) that will replace individuals on the superior strata. Corroborating with desiccation tolerance, the wood density showed a prevalence of individuals with heavy wood (more advanced successional stage) in the lower stratum, showing once again the replacement of individuals of intermediate successional stage.

Ap?s c?lculo amostral, 720 campos microsc?picos foram utilizados para mensura??o da espessura total do epit?lio de l?ngua (camada epitelial mais camada c?rnea). Quarenta hamsters foram divididos em dois grupos experimentais, conforme aplica??o da subst?ncia teste, em grupo 1 (cacha?a 48?gl) e grupo 2 (u?sque 40?gl), ambos avaliados em per?odos experimentais de 13 e 20 semanas. A borda contralateral da l?ngua, que n?o recebeu a subst?ncia teste, foi utilizada como controle. Ap?s eutan?sia, as l?nguas foram dissecadas, fixadas em solu??o de formol 10% e processadas para a obten??o de cortes histol?gicos, que foram corados pela t?cnica de hematoxilina e eosina (HE). Para a an?lise morfom?trica, tr?s l?minas por esp?cime foram avaliadas. A espessura do epit?lio, de ambas as bordas da l?ngua, foi mensurada com aux?lio do Programa Motic Images Plus 2.0 (Motic?). Os dados da an?lise morfom?trica foram avaliados pela estat?stica descritiva e teste de Wilcoxon e teste de Mann-Whitney. No grupo cacha?a, em rela??o ? espessura total do epit?lio, houve diferen?a estat?stica significativa entre a m?dia do lado teste, 61,87 (14,75)?m e a m?dia do lado controle, de 67,20 (9,96)?m (p=0,044). Tamb?m observou-se uma redu??o altamente significativa da espessura das camadas epitelial (p<0,001) e c?rnea (p=0,021). No per?odo de 13 semanas, houve diminui??o estat?stica significativa da espessura das camadas c?rnea (p=0,032) e epitelial (p<0,001), enquanto que, em 20 semanas, somente a camada epitelial apresentou-se significativamente reduzida (p=0,002). No grupo u?sque houve aumento significativo da espessura da camada c?rnea (p=0,015) e epitelial (p=0,012) em 13 semanas. Conclui-se que tipos diferentes de bebidas alco?licas destiladas, com concentra??o alco?lica entre 40?gl e 48?gl, promoveram altera??es morfom?tricas e morfol?gicas diferenciadas. A cacha?a promoveu atrofia epitelial, o que poderia facilitar a penetra??o de sust?ncias ou agentes carcinog?nicos. J? o u?sque promoveu hiperplasia, podendo assim sugerir o in?cio do desenvolvimento de les?es pr?-malignas. / Disserta??o (Mestrado) ?

Forty hamsters were divided into two groups, depending on the application of the test substance in group 1 (cacha?a 48?gl) and group 2 (whiskey 40?gl), both evaluated in the experimental periods of 13 and 20 weeks. The contralateral side of the tongue, which has not received the test substance was used as control. After euthanasia, the tongues were dissected, fixed in 10% formalin solution, processed to obtain histological sections and were stained by hematoxylin and eosin (HE). For the morphometric analysis, three slides per specimen were evaluated. The thickness of the epithelium, both edges of the tongue, was measured with the aid of the program Motic Images Plus 2.0 (Motic ?). Data from morphometric analysis were evaluated by descriptive statistics and by Wilcoxon and Mann-Whitney tests. In cacha?a group, regarding the total thickness of the epithelium, there was a statistically significant difference between the average of the test side, 61.87 (14.75) ?m and the average of the control side, 67.20 (9.96) ?m (p=0.044). It was also observed a highly significant reduction in the thickness of the epithelium (p<0.001) and the cornea (p=0.021). At 13 weeks, there was a statistically significant decrease in the thickness of the cornea (p=0.032) and epithelial (p<0.001), whereas at 20 weeks, only the epithelial layer was significantly reduced (p=0.002). In the Whiskey group, there was a significant increase in thickness of the cornea (p=0.015) and epithelial (p=0.012) at 13 weeks. It was conclude that different types of distilled spirits with alcohol concentration between 40 ?gl ?and 48 ?gl, promoted ?morphological and morphometric changes differentiated. Cacha?a promoted epithelial atrophy, which could facilitate the penetration of substances give or carcinogens. The whiskey promoted hyperplasia which suggest the early development of premalignant lesions.

O objetivo desta pesquisa foi avaliar as condi??es bucais e sist?micas de portadores HIV/AIDS atendidos pelo Programa Municipal de DST-AIDS de Diamantina, provenientes de 24 munic?pios do Vale do Jequitinhonha. Para isso, foram avaliados 118 pacientes com HIV-AIDS. Foram observadas as condi??es de sa?de bucal e geral dos pacientes, condi??es socioecon?micas, aspectos epidemiol?gicos da infec??o pelo HIV (forma de contamina??o e de diagn?stico), uso de terapia antirretroviral de alta pot?ncia (HAART), contagem de linf?citos T CD4, h?bitos presentes (fumo, ?lcool e outras drogas), bem como o acesso destes pacientes a servi?os de Odontologia. Os resultados revelaram que a maioria dos pacientes pertencia ao g?nero masculino (53,4%), a m?dia de idade encontrada foi de 39,7 anos, a forma de contamina??o de 98,3% dos pacientes foi por via sexual e a renda familiar de 44,9% dos pacientes foi de at? 1 (um) sal?rio m?nimo mensal. Foi observado um alto ?ndice de doen?as e les?es bucais, sendo as mais prevalentes as doen?as periodontais (70,3%), a hiperpigmenta??o da mucosa (52,5%), a queilite angular (32,2%) e ulcera??es aftosas recorrentes (29,7%). A hiperpigmenta??o de mucosa parece ser mais frequente entre pacientes em uso de HAART e em tabagistas. A candidose bucal foi associada com diabetes, anemia, xerostomia, uso de HAART e taxa de CD4 > 500 cel/mm3, enquanto a ulcera??o aftosa recorrente foi associada com tabagismo, etilismo e xerostomia. / ABSTRACT The research entitled "Oral Health of HIV-AIDS patients: influence of local and systemic factors" was held during the year 2012 in Diamantina, Minas Gerais. The aim of this research was to evaluate the oral and systemic conditions of patients with HIV / AIDS attended by Municipal DST-AIDS of Diamantina, from 24 cities of Jequitinhonha Valley. To do this, 118 patients with HIV-AIDS were evaluated. The patients were observed about their conditions of oral and general health, socioeconomic aspects, epidemiological aspects of HIV infection (form of contamination and diagnosis), use of highly active antiretroviral therapy (HAART), CD4 count, customs(smoking, alcohol and other drugs), as well as access of these patients to dental services. The results revealed that most of the patients were males (53.4%), mean age was 39.7 years, the form of contamination of 98.3% of patients was through sex and the family income of 44.9% of patients is a monthly wage like $362,00. There was a high rate of disease and oral lesions, the most prevalent periodontal diseases (70.3%), mucosal hyperpigmentation (52.5%), angular cheilitis (32.2%) and recurrent aphthous ulcerations ( 29.7%). Hyperpigmentation of mucosa seems to be more frequent among patients on HAART and in smokers. Oral candidiasis was associated with diabetes, anemia, xerostomia, HAART use and CD4 count> 500 cells/mm3, while recurrent aphthous ulceration was associated with smoking, alcohol and xerostomia.

Apesar de ser uma das oler?colas mais cultivada no Brasil e apresentar grande potencial de uso na alimenta??o humana, animal e industrial, tem sido pouco estudada. O objetivo deste trabalho foi identificar clones superiores e avaliar a produ??o e a qualidade de ra?zes, ramas e silagem de ramas de clones de batata-doce em diferentes ?pocas de colheita e ambientes de cultivo. Foi realizado um experimento no Campus II e outro na Fazenda Forquilha, ambos localizados no munic?pio de Diamantina-MG, com tr?s ?pocas de colheita. Foram avaliados nas ra?zes tuberosas: a produtividade total, produtividade comercial, peso m?dio total, peso m?dio comercial, resist?ncia a insetos de solo, formato de ra?zes, prote?na bruta, fibra bruta, cinzas, amido, compostos fen?licos e herdabilidade. Na parte a?rea foi avaliado a produtividade de mat?ria verde, teor de mat?ria seca, produtividade de mat?ria seca, prote?na bruta e fibra bruta. Foi feito silagem das ramas aos 150 dias ap?s a colheita na Fazenda Forquilha, onde foi analisado prote?na bruta, FDA, FDN, NDT, pH, mat?ria seca, hemicelulose e nitrog?nio amoniacal em rela??o ao nitrog?nio total. Atrav?s dos resultados apresentados, percebe-se que Os clones BD-25, BD-38 e BD-45, na Fazenda Forquilha, apresentaram as maiores produtividade totais e comercial de ra?zes e devem ser colhidas mais tardiamente. A Fazenda Forquilha foi o local onde os clones de batata-doce apresentaram, em m?dia, as maiores produtividades totais e comercial de ra?zes e os maiores pesos m?dios de ra?zes total e comercial. As menores notas para formato de ra?zes foram obtidas nas colheitas mais precoces. Os teores de prote?na bruta, fibra bruta, cinzas e amido, na mat?ria seca de ra?zes, n?o foram influenciados pelos ambientes de cultivo. Para obten??o de maiores produtividades de mat?ria verde e mat?ria seca, as ramas devem ser colhidas at? 150 dias ap?s o plantio. Na Fazenda Forquilha foram obtidas as maiores produtividades de mat?ria verde e mat?ria seca das ramas. Os teores de mat?ria seca nas ramas aumentam com o ciclo da cultura. As ramas de batata-doce apresentam potencial de utiliza??o na alimenta??o animal, tanto na forma fresca como na forma de silagem. / Disserta??o (Mestrado) ?

Despite being one of most vegetables grown in Brazil and show great potential for use in food, animal and industrial, have been little studied. The objective was to identify superior clones and assess the production and quality of roots, stems and branches of silage from sweet potato clones in different harvesting periods and environments of cultivation. An experiment was conducted on campus and another on Farm II forks, both located in the city of Diamantina-MG with three seasons of harvest. Roots were evaluated in the total yield, commercial yield, total weight, weight commercial, insect resistance of soil, shape of roots, crude protein, crude fiber, ash, starch, phenolic compounds and heritability. In shoots was evaluated the yield of green matter, dry matter yield of dry matter, crude protein and crude fiber. Silage was made of branches to 150 days after harvest at Farm forks, where it was considered crude protein, ADF, NDF, TDN, pH, dry matter, hemicellulose and ammonia nitrogen in relation to total nitrogen. The results presented, we find that the BD-25 clones, and BD-38 BD-45, at Farm forks, submitted the highest total and commercial yield of roots and should be harvested later. The Farm was the fork where the sweet potato clones showed, I mean, the highest total and commercial yields of roots and the highest average weight of roots and total trade. The lowest notes to format roots were in earlier harvests. The crude protein, crude fiber, ash and starch in dry matter of roots were not influenced by the environment of cultivation. To obtain higher yields of green matter and dry, the stems should be harvested up to 150 days after planting. Farm forks were obtained in the highest yield of green matter and dry matter of branches. The dry matter in branches increased with the crop cycle. The stems of sweet potato, have potential for use in animal feed, both as fresh and as silage.

O experimento foi conduzido na Fazenda Experimental do Moura, pertencente ? Universidade Federal dos Vales do Jequitinhonha e Mucuri (UFVJM), localizada no Munic?pio de Curvelo, Minas Gerais. Para a avalia??o das caracter?sticas produtivas, estruturais e bromatol?gicas foi utilizado o delineamento inteiramente casualizado com medidas repetidas no tempo, com quatro ciclos de pastejo e duas estrat?gias de pastejo. Para o consumo dos animais foi utilizado o delineamento inteiramente casualizado em arranjo fatorial 2 x 3, sendo duas estrat?gias de pastejo e tr?s dias de ocupa??o, e para a taxa de lota??o utilizou-se o arranjo 2 x 4 (duas estrat?gias e quatro ciclos de pastejo). N?o houve efeito para as vari?veis: disponibilidade, estrutura e composi??o bromatol?gica da forragem, com exce??o para intercepta??o luminosa e prote?na bruta, onde o tratamento com IL obteve maior valor de intercepta??o luminosa (2,73% superior que o DF) e menor teor de PB (1,08% inferior ao tratamento DF). Para o consumo de mat?ria seca houve efeito (P<0,05) entre os dias de ocupa??o, sendo os maiores valores encontrados no primeiro dia (9,84 kg de MS) e os menores no terceiro dia de ocupa??o (6,21 kg de MS). A taxa de lota??o foi 0,76 UA maior para a estrat?gia de manejo com IL, quando comparada ao tratamento DF. Assim, tendo em vista a praticidade de ado??o, boas condi??es edafoclim?ticas, o manejo de pastejo com intensifica??o dos dias fixos apresenta grande potencialidade para uso de pasto. / Disserta??o (Mestrado Profissional) ?

The experiment was conducted at the Moura Experimental Farm, belonging to Universidade Feseral dos Vales do Jequitinhonha e Mucuri (UFVJM), in Curvelo, Minas Gerais. For the evaluation of productive, structural and nutritive characteristics, we used a completely randomized design with repeated measures in the time, with four grazing cycles and two grazing strategies. For consumption of animals, we used a completely randomized design, in a 2 x 3 factorial, with two grazing strategies and three days of occupation, and 2 x 4 scheme (two strategies and four cycles of grazing) for stocking rate. There was no effect for the variables: availability, structure and chemical composition of forage, except for light interception and crude protein, in which treatment with LI showed the highest value of light interception (2.73% higher than the fixed days) and lower content of CP (1.08% lower than the fixed days treatment). There was effect for dry matter intake (P <0.05) between the days of occupation, and the highest values found on the first day (9.84 kg DM) and the lowest on the third day of occupation (6.21 kg DM). The stocking rate was 0.76 AU added to the management strategy with LI compared to treatment fixed days. Thus, taking into account practicality of adoption, good soil and climatic conditions, grazing management with intensification of fixed days shows great potential for pasture use.

The study was conducted at the Experimental Farm of Moura- UFVJM, located in Curvelo MG. A completely randomized design in a factorial 3 x 3, three species of tropical forage legumes was adopted (Stilosanthes Campo Grande, Kudzu and Macrotyloma) and three stages of dehydration (Phase 1: 0 to 8 am; 2nd phase: 12 to 20h; and phase 3: 24 to 32 hours of drying), with four replications. Differences between means were analyzed by the Tukey test (p <0.05). The foragers were manually cut, chopped and spread on plastic sheeting to optimize the dehydration. The dehydration of fodder began at 9:00 am on 21 February. The sampling procedure was performed every 2 hours on the first day and every 4 hours in the second and third days. In the time previously established, samples were identified, weighed and subjected to forced circulation oven temperature 55?C for 72h for pre-drying. For the determination of the dehydration curve and quantifying the loss of nutrients during dehydration were performed the following chemical analysis: dry matter (DM), mineral matter (MM), neutral detergent fiber corrected for ash and protein (NDFap), acid detergent fiber (ADF), ether extract (EE), crude protein (CP), non-protein nitrogen (NPN) and soluble carbohydrates (SCHO). It was also estimated the total carbohydrates (TCH), non-fibrous carbohydrate (NFC) and total digestible nutrients (TDN). During dehydration curve was greater drying efficiency for Stilosanthes and Kudzu species. At the end of the assessment times, Macrotyloma presents moisture content higher than recommended for storage. The three legumes have increasing the dry matter content due to the dehydration time. No effects for MM, NDF, FDA, CNF, CHT and NDT during the dehydration curve. The Stilosanthes and Macrotyloma showed loss in EE levels in the first phase, the Macrotyloma showed the highest EE levels among the studied species. The Kudzu has increased in the first phase CP content for the second and was legume with the highest content of this nutrient among the studied legumes. The three legumes have reduced the NPN content in the first to the second phase of dehydration curve. The Macrotyloma was the only legume that decreased the SCHO contents during dehydration curve and legumes that presented the highest levels of this constituent. The Stilosanthes was legume that presented the most efficient dehydration during the haying process, coming faster to the moisture content recommended for storage.

Com o advento do marco regulat?rio de ci?ncia, tecnologia e inova??o (Lei n? 13.243/2016), o qual alterou a lei de inova??o em vigor (Lei n? 10.973/2004), as chamadas Institui??es Cient?ficas, Tecnol?gicas e de Inova??o (ICTs), caso da UFVJM, foram desafiadas no sentido de instituir a sua pol?tica de inova??o, consoante ?s diretrizes e objetivos legalmente estabelecidos. Nessa perspectiva, este estudo tem como objetivo geral propor considera??es que possam contribuir para o debate junto ? comunidade universit?ria visando o aperfei?oamento do marco regulat?rio das pol?ticas de propriedade intelectual e inova??o tecnol?gica da UFVJM. Visando alcan?ar esse prop?sito, foram estabelecidos como objetivos espec?ficos aferir a conformidade da regulamenta??o das pol?ticas de propriedade intelectual e inova??o tecnol?gica da UFVJM com a Lei n? 10.973/2004 e discutir sua rela??o com as principais quest?es tratadas no escopo metajur?dico deste trabalho; e avaliar a compatibilidade entre a regulamenta??o das pol?ticas de propriedade intelectual e inova??o tecnol?gica da UFVJM com as necessidades dessa universidade, tendo como base o Plano de Desenvolvimento Institucional- PDI da institui??o. Nesse sentido, metodologicamente esta pesquisa ? descritiva, com vi?s bibliogr?fico e documental, efetivada em livros, revistas, artigos e p?ginas da internet. A pesquisa bibliogr?fica, que fundamenta este estudo, foi desenvolvida com a contribui??o de diversos autores, precipuamente no referencial te?rico denominado Escopos Jur?dicos e Metajur?dicos. Por sua vez, a pesquisa documental foi realizada tendo como alicerce a Constitui??o da Rep?blica Federativa do Brasil de 1988, Lei n? 9.279/1996, Lei n? 9.394/1996, Lei n? 10.973/2004, Lei n? 17.348, de 17 de janeiro de 2008 (lei mineira de inova??o), Delibera??o da Funda??o de Amparo ? Pesquisa do Estado de Minas Gerais (Fapemig) n? 72, de 13 de agosto de 2013, Lei n? 13.243/2016 e resolu??es da UFVJM. Concluiu-se pela necessidade de a UFVJM regulamentar a sua pol?tica de propriedade intelectual e inova??o tecnol?gica, de forma integral em um ?nico documento. Ponderou-se ainda que a constru??o e regulamenta??o de tais pol?ticas levem em considera??o as principais necessidades da UFVJM dispostas em seu Plano de Desenvolvimento Institucional (PDI). Por fim, recomenda-se que a regulamenta??o de tais pol?ticas busque fomentar e consolidar o desenvolvimento socioecon?mico da regi?o de abrang?ncia da UFVJM. Dessa forma, espera-se que este trabalho possa contribuir para o desenvolvimento cient?fico, tecnol?gico e intelectual desta institui??o federal de ensino superior. / Disserta??o (Mestrado Profissional) ? Programa de P?s-Gradua??o em Educa??o, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2017. / The present work constitutes a case study and has as object of study the regulation of the institutional policy of intellectual property and technological innovation of the Federal University of the Jequitinhonha and Mucuri Valleys (UFVJM). With the advent of the regulatory framework for science, technology and innovation (Law n? 13.243 / 2016), which amended the current innovation law (Law 10.973 / 2004), the so-called Scientific, Technological and Innovation Institutions (ICTs) in the case of the UFVJM, were challenged in order to establish their innovation policy, according to legally established goals and guidelines. In this perspective, this study has as general objective to propose considerations that can contribute to the debate with the university community aiming at perfecting the regulatory framework of the intellectual property policies and technological innovation of the UFVJM. In order to achieve this purpose, it was established as specific objectives to verify the compliance of the regulation of intellectual property policies and technological innovation of UFVJM with Law 10,973 / 2004 and discuss its relationship with the main issues addressed in the metajuridic scope of this work; and to evaluate the compatibility between the regulation of intellectual property policies and technological innovation of UFVJM with the needs of that university, based on the Institutional Development Plan - PDI of the institution. In this sense, methodologically, this research is descriptive, with a bibliographic and documentary bias, carried out in books, magazines, articles and internet pages. The bibliographical research, which bases this study, was developed with the contribution of several authors, mainly in the theoretical framework called Juridical and Metajuridic Scopes. On the other hand, documentary research was carried out with the foundation of the Constitution of the Federative Republic of Brazil of 1988, Law 9,279 / 1996, Law 9,394 / 1996, Law 10,973 / 2004, Law 17,348, of January 17, 2008 (Mining Law for Innovation), Determination of the Foundation for Support of Research of the State of Minas Gerais (Fapemig) n? 72, of August 13, 2013, Law n? 13.243 / 2016 and resolutions of the UFVJM. It was concluded by the need for the UFVJM to regulate its policy of intellectual property and technological innovation, in an integral form in a single document. It was also pointed out that the construction and regulation of such policies take into account the main needs of the UFVJM set forth in its Institutional Development Plan (IDP). Finally, it is recommended that the regulation of such policies seek to foster and consolidate the socioeconomic development of the UFVJM's region. Thus, it is expected that this work can contribute to the scientific, technological and intellectual development of this federal institution of higher education.
