Nessas ?reas encontra-se um sistema de drenagem superficial com uma vegeta??o arb?reo-arbustiva e gram?neas, comumente denominadas de ?veredas?. O objetivo deste trabalho foi caracterizar morfol?gica, micromorfologica, quimica, fisica e mineralogicamente uma topossequ?ncia formada por Latossolo Vermelho Amarelo, Latossolo Amarelo, ?Latossolo Acinzentado? e Gleissolo representativos dos solos da microbacia da Vereda Lagoa do Leandro, localizada no munic?pio de Minas Novas - MG, enfatizando aspectos de sua g?nese e da evolu??o da paisagem nas chapadas do Alto Vale do Jequitinhonha. A topossequ?ncia est? embasada em rochas do Grupo Maca?bas e o clima ? tropical com esta??o seca de inverno. O Cerrado era a cobertura vegetal nativa nas ?reas de entorno da Vereda Lagoa do Leandro e foi substitu?do pelo reflorestamento com Eucaliptus sp. Os perfis ocupam as seguintes posi??es na vertente: topo - Latossolo Vermelho (LVA), ter?o m?dio de vertente - Latossolo Amarelo (LA), sop? - ?Latossolo Acinzentado? (?LAC?) e base da vereda - Gleissolo (GXbd). Esses perfis foram descritos e coletadas amostras deformadas e indeformadas para realiza??o das an?lises f?sicas, qu?micas, mineral?gicas e micromorfol?gicas. A Vereda Lagoa do Leandro ? caracterizada como de superf?cie tabular ocupando uma ?rea de aproximadamente 59 hectares. Os solos das partes mais elevadas da vertente apresentaram atributos morfol?gicos, f?sicos, qu?micos e mineral?gicos t?picos da classe dos Latossolos. No entanto, na base da vereda encontra-se o GXbd apresentando cores acinzentadas, forte gradiente textural e estrutura maci?a. A diminui??o de Fe cristalino e de baixa cristalinidade ao longo da vertente confirmou a perda de Fe e refletiu a cor dos solos. Os teores de Si e Al foram mais baixos no ?LAC?. Houve uma diminui??o da rela??o Fe2O3/TiO2 vertente abaixo, indicando impedimentos ? drenagem ao longo da topossequ?ncia. A mineralogia da fra??o argila em todos os solos ? dominada pela caulinita. Nos LVA e LA foram identificadas goethita, gibbsita e anat?sio, em ?LAC? anat?sio, em GXbd ilita, anat?sio e tra?os de vermiculita. A micromorfologia mostra a predomin?ncia da microestrutura tipo granular ou microagregados e porosidade do tipo empilhamento/empacotamento, t?picos de Latossolos, em LVA, LA e ?LAC?. No GXbd predomina a estrutura maci?a, com a presen?a de cut?s de iluvia??o e ferri-argil?s. Os solos e a paisagem da Vereda Lagoa do Leandro foram formados e evolu?ram juntamente com a instala??o e desenvolvimento da rede de drenagem que, por sua vez, est? relacionada com mudan?as clim?ticas pleistoc?nicas. Paleogleissolos foram latolizados pela a??o da fauna escavadora e deram origem aos atuais ?LAC?. Os GXbd da base da vereda preservaram atributos f?sicos, mineral?gicos e micromorfol?gicos que tiveram suas g?neses em per?odos secos. A g?nese e os atributos dos solos do sop? e da base das veredas das chapadas do Alto Vale do Jequitinhonha - MG s?o fortemente influenciados pela presen?a do len?ol fre?tico na superf?cie ou pr?ximo ? superf?cie o ano todo, no presente e/ou no passado. / Disserta??o (Mestrado) ? Programa de P?s-Gradua??o em Produ??o Vegetal, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2010. / ABSTRACT In the Alto Vale do Jequitinhonha there are large areas of flattened relief dominated by ?chapadas?, that are separated by areas dissected by tributaries of the river Jequitinhonha and Ara?ua?. In these areas there is one surface drainage system with a vegetation of trees and shrubs and grasses, commonly called ?Veredas?. The objective of this study was to characterize morphological, micromorphological, chemical, physical and mineralogically a toposequence formed by a Red Yellow Oxisol, Yellow Oxisol, ?Gray Oxisol? and Haplix Gleisol representative of soils in the watershed Vereda Lagoa do Leandro, located in Minas Gerais State, emphasizing aspects of its genesis and evolution of the landscape in the chapadas of the Alto Jequitinhonha. The toposequence is grounded by Maca?bas Group rocks, the climate is tropical with winter?s dry season. The Cerrado was the native vegetation in areas surrounding the Vereda Lagoa do Leandro and was replaced by the reforestation with Eucalyptus sp. The profiles occupy the following positions in the hillside: top - a Red Yellow Oxisol (LVA), the middle slope ? Yellow Oxisol (LA), the footslope ? ?Gray Oxisol? (?LAC?) and on the basis of the palm swanp ? Hasplic Gleisol (GXbd). These profiles were described and sampled and to carry out the physical analysis, chemical, mineralogical and micromorphological. The Vereda Lagoa do Leandro is characterized as tabular surface covering an area of approximately 59 hectares. The soils of the higher parts of the case showed the morphological, physical, chemical and mineralogical typical of Oxisols. However, at the base of the path is GXbd presenting the colors gray, strong texture gradient and massive structure. The reduction of crystalline Fe and amorphous over the case confirmed the loss of Fe and reflected the color of the soil. The contents of Si and Al were lower in the ?LAC?. There was a decrease in the case Fe2O3/TiO2 below hillside, indicating impediments to drainage along the toposequence. The clay mineralogy in all soils is dominated by kaolinite. In LVA and LA were identified goethite, gibbsite and anatase in ?LAC? anatase in GXbd illite, anatase and traces of vermiculite. Micromorphology shows the prevalence of type or granular microstructure and porosity of the micro-type stacking / packaging, typical of Oxisols, in LVA, LA and ?LAC?. In GXbd dominates the massive structure, with the presence of illuviation cutans and ferriargillans. The soils and the landscape of the Vereda Lagoa do Leandro were formed and evolved along with the installation and development of the drainage network, which in turn is related to Pleistocene climate change. Paleogleissols were latolization the action of the excavator and fauna led to the genesis of the ?LAC?. The GXbd the base of the palm swamp preserved the physical, mineralogical and micromorphological that had their genesis in dry periods. The genesis and characteristics of the soils of the topossequence and on the footslope and the basis of the palm swamp of the Chapadas of the Alto Jequitinhonha - MG are strongly influenced by the presence of ground water on the surface or near the surface all year, in present and/ or in past.

Foram utilizadas 1200 larvas de uma mesma desova, com 10 dias ap?s a eclos?o, comprimento inicial de 11,58 mm e peso m?dio de 189 mg distribuidas em 20 aqu?rios com 6 L de ?gua (60 larvas/aqu?rio), em uma densidade de 10 larvas/L. As larvas foram submetidas a cinco tratamentos, quatro tipos de biofiltros internos compostos por: concha?brita, cascalho, porcelana, brita e um controle, sem biofiltro, distribu?das em um delineamento inteiramente ao acaso, com cinco tratamentos e quatro repeti??es. Os biofiltros compostos por concha/brita e porcelana obtiveram os melhores resultados em nitrato, nitrito e am?nia, indicando melhor efici?ncia no processo de biofiltra??o. A maior condutividade e pH porporcionada pelo concha/brita em rela??o ao porcelana, indica uma maior capacidade de tamponamento e manuten??o de qualidade de ?gua. O oxig?nio que n?o diferiu entre os tratamentos, esteve adequado para a esp?cie e para a recircula??o de ?gua. As sobreviv?ncias foram similares, mas verificou-se uma tend?ncia decrescente do concha/brita para a porcelana, cascalho, brita e sem substrato. Nos par?metros morfom?tricos, os biofiltros porcelana e cascalho diferenciaram dos demais tratamentos, apresentando os melhores resultados. Com os resultados obtidos, sugere-se a utiliza??o de biofiltro composto por porcelana ou concha/brita devido a maior efici?ncia nos par?metros limnol?gicos e morfom?tricos, associados a sobreviv?ncia na larvicultura de til?pias do Nilo. / Disserta??o (Mestrado) ?

Larvae were subjected to five treatments, four types of internal biofilters made of: shell?crushed stone, gravel, porcelain, crushed stone and a control without biofilter, distributed in a completely randomized design with five treatments and four replications. The biofilter composed of shell/gravel and porcelain have the best results in nitrate, nitrite and ammonia, indicating greater efficiency in the process of biofiltration. The higher conductivity and pH by proportional shell/gravel over the porcelain, indicates a higher buffering capacity and maintenance of water quality. The oxygen did not differ between treatments, was suitable for the species and for water recirculation. The survivals were similar, but there was a downward trend in the shell/gravel for the porcelain, gravel, crushed stone and without substrate. In the morphometric parameters, the porcelain and gravel biofilters differed from other treatments, delivering the best results .With these results, we suggest the use of biofilter composed of porcelain or shell/gravel due to greater efficiency in limnological and morphometric parameters associated with survival in Nile tilapia hatchery.

The experiment was conducted at the UFVJM?s Laboratory of Aquaculture, between July 21 and August 3, 2011. Post-larvae of Nile tilapia in the density of 13.3 post larvae/L were grown in aquariums containing biofilters with 100% calcareous shell, 70% calcareous shell/30% gravel, 50% calcareous shell/50% gravel, 30% calcareous shell/70% gravel, 10% calcareous shell/90% gravel and 100% gravel; and as control sample, a aquarium without biofilter in DIC, summing seven treatments with three replications. Limnological and biometric data were submitted to ANOVA and measurements were compared by Duncan test at p?0.05. To compare the treatments that have evolved a proportion of calcareous shell/gravel, there has been carried out a regression analysis considering a significance level of 5%. All concentrations of calcareous shell/gravel did not influence negatively on morphological parameters and kept water conditions suitable for the cultivation of Nile tilapia, except for the observed levels of ammonia, which were mostly above the recommended for tilapia. However, the apparent non-toxicity of ammonia in the present study may be related to pH values, which remained close to neutral allowing a lower toxicity of the ammonium ion. The proportion of 30% calcareous shell and 70% gravel substrate is recommended as biofilter for presenting the best rate of nitrification during the experiment.

The treatments consisted of: TControl (n=35)- Day 0, insertion of intravaginal progesterone device and application of 2 mg estradiol benzoate, intramuscular (IM), Day 8, removed from the device and application of 0.53 mg PGF2? and 1 mg estradiol benzoate, IM; Day 10, TAI performed 44 h after removal of the device; TFSH (n=36)- similar to TControl, but with the application on day 8 of 15 mg of FSH-p; TFNOV (n=24)- similar to TFSH but using heifers. At the end of the work observed that was an interaction (P <0.05) analyzed the effects for BW and BCS with treatments. There was no effect for days postpartum (P> 0.05). There were difference (P <0.05) between the mean body weight among the cows (and TFSH TControl) compared with heifers (TFNOV). There was no effect (P> 0.05) between protocols, body weight and body condition on return to estrus in coverage with the bull and accumulated pregnancy. There was no effect (P> 0.05) between the protocols and return to estrus and pregnancy rates of TAI, the bull and the accumulated coverage. Even the use of FSH-p does not influence the reproductive efficiency, the cumulative pregnancy rate was found satisfactory in both treatments, thus concludes the TAI as interesting biotech for use in animal production, but it is important to have a good nutritional monitoring of animals, because the relationship between nutrition and reproduction.

No primeiro experimento foram realizadas observa??es diretas dos comportamentos da equipe de ordenha (conversar, tatear, nomear, bater, gritar e empurrar) e das vacas (defeca??o, mic??o, rumina??o, movimenta??o dos membros posteriores, vocaliza??o e reatividade), al?m do tempo de perman?ncia em sala de ordenha (TPO) e tempo de ordenha (TOR). Ap?s a ordenha foram realizados testes de dist?ncia de fuga no pasto. Foram encontradas intera??es (P<0,05) nas a??es comportamentais da equipe de ordenha e dos animais. Encontrou-se efeito (P<0,05) sobre as medianas dos testes de dist?ncia de fuga do ordenhador e uma pessoa desconhecida. Houve intera??o (P<0,01) em rela??o ao TPO e TOR entre as a??es positivas e aversivas da equipe de ordenha, demonstrando varia??o dos tempos de acordo com o comportamento humano. Encontrou-se intera??o (P<0,05) entre TPO e os comportamentos do animal: rumina??o e vocaliza??o. O TOR n?o foi influenciado (P>0,05) pelo comportamento animal. O comportamento aversivo da equipe de ordenha altera o comportamento de vacas leiteiras na sala de ordenha, al?m de influenciar o TPO e TOR, o que consequentemente compromete a produ??o e qualidade do leite. No segundo experimento os dados foram coletados em dez propriedades leiteiras, representando os n?veis tecnol?gicos baixo, m?dio e alto. A condi??o corporal foi medida pelo m?todo de avalia??o visual, simultaneamente, por 2 avaliadores. O California Mastitis Test (CMT) foi realizado ap?s a entrada dos animais na sala de ordenha, sempre na ordenha da manh?. N?o houve diferen?a (P>0,05) nas medianas dos TPO e TOR com rela??o ao n?vel tecnol?gico da propriedade.

The experiments were conducted in the north / northeast of Minas Gerais, in the municipalities of Porteirinha, Pai Pedro, Quem-Quem, Ja?ba, Jana?ba e Capit?o En?as in the period from November, 2011 to January, 2012. In the first experiment, there were carried out direct observations of the behaviors of the milking team (talking, groping, name, hitting, yelling and pushing) and cows (defecation, urination, rumination, hind limb movement, vocalization and reactivity), as also the time stay in the milking parlor (TPO) and milking time (TOR). After milking, tests were carried away to escape the pasture. Interactions were observed (P <0.05) in the behavioral actions of staff and milking animals. Effect was found (P <0.05) on the median distance of flight tests of the milker and an unknown person. There was an interaction (P <0.01) compared to TPO and TOR actions between "positive" and "negative" milking team, showing variation of time in accordance with human behavior. Interaction was found (P <0.05) between TPO and behavior of the animal, "rumination" and "vocalization." The TOR was not affected (P> 0.05) for animal behavior. The aversive behavior team changes the behavior of milking cows in the milking parlor, besides influencing the TPO and TOR, which consequently impairs the production and quality of milk. In the second experiment the data were collected in ten dairy farms, representing the technological levels low, medium and high. We recorded the time spent in the milking parlor (TPO) and milking time (TOR). Body condition was measured by visual evaluation simultaneously by two evaluators. The California Mastitis Test (CMT) was performed after the animals enter the milking parlor, where the morning milking. There was no difference (P> 0.05) in the median TPO and TOR with respect to the technological level of the property. Differences were found (P <0.001) in the prevalence of subclinical mastitis among technological levels, being 5.54%, 29.79% and 15% for technological levels 1, 2 and 3, respectively. Found - differences (P <0.05) in median ECC regarding the technological level of the property. The technological level influenced the prevalence of mastitis, the ECC and compromised the welfare of animals.

Foram utilizadas cinco vacas com 150 ? 14 dias de lacta??o e produ??o m?dia de 7,1 ? 2,1 kg/dia de leite, distribu?das no delineamento em quadrado latino 5 x 5. Os tratamentos foram constitu?dos por dietas contendo soja que passou por diferentes processamentos e soja gr?o in natura sendo que, todos os animais receberam de forma casualizada, um dos seguintes tratamentos: concentrado a base de farelo de soja (FS); concentrado a base de gr?o de soja (SGC); concentrado a base de gr?o de soja triturado (STC); concentrado a base de gr?o de soja tostado (SGT) e concentrado a base de gr?o de soja triturado e tostado (STT). Os consumos de mat?ria seca (MS), mat?ria org?nica (MO), prote?na bruta (PB), fibra em detergente neutro (FDN), carboidratos totais (CHO) e nutrientes digest?veis totais (NDT) n?o foram influenciados pela dieta, entretanto o consumo de extrato et?reo (EE) foi superior para os animais que receberam dietas com inclus?o de soja em rela??o aos que receberam farelo de soja. As digestibilidades da MS, MO, FDN, PB e EE n?o diferiram, enquanto que a digestibilidade dos CHO foi alterada em fun??o da dieta. A produ??o de leite corrigida diferiu entre as dietas, sendo que o tratamento com SGC foi o que propiciou a menor produ??o de leite em rela??o aos demais tratamentos que n?o diferiram entre si. A composi??o do leite n?o variou independente da forma de utiliza??o da soja. Conclui-se, portanto, que o farelo de soja pode ser substitu?do pela soja gr?o triturada ou pela soja tostada, triturada ou n?o em dietas de vacas de baixa produ??o em pastagem de Brachiaria decumbens sem que haja preju?zo na produ??o e composi??o do leite. Assim, recomenda-se o uso destas mat?rias primas alternativas sempre que sua inclus?o representar menor custo da dieta. / Disserta??o (Mestrado) ?

Five cows with 150 ? 14 days of lactation and average production of 7,1 ? 2,1 kg/day of milk were assigned in a Latin Square 5 x 5. The treatments were constituted of a diet control composed of soybean treated under different processing?s and soya bean in natura, and all the animals received, in a casualized way, one of the following treatments: concentrated based on soybean meal (FS); concentrated based on raw soybean (SGC); concentrated based on raw ground soybean (STC); concentrated based on roasted soybean (SGT); and concentrate based on roasted soybean ground (STT). The intake of dry matter (MS), organic matter (MO), crude protein (PB) neutral detergent fiber (FDN), total carbohydrates (CHO) and total digestible nutrients (NDT) were not influenced by diet, however the intake of ether extract (EE) was higher for animals fed with diets with soybean added compared with those fed with soybean meal. The digestibility of MS, MO, FDN, PB and EE did not differ, whereas the digestibility of CHO was changed due to the diet. The corrected milk production differed between treatments, and treatment with raw soybean had the lowest milk production in relation to the other treatments that did not differ among themselves. Milk composition did not vary independently of the type of soybeans used. It is concluded therefore that the soybean meal can be replaced by soya bean crushed or by the roasted soybean, ground or not in diets of cows with low production in Brachiaria decumbens pastures with no loss in milk?s production and composition. Therefore, it is recommended the use of these alternative feeds whenever they present a lower market price.

Pesquisa do estado de Minas Gerais (FAPEMIG) / A oxida??o de efluentes sint?ticos contendo os f?rmacos paracetamol (PCT) e dipirona (DPN), ambos analg?sicos largamente utilizados por humanos e animais foi conduzida pelos processos O3, O3/UV, H2O2/UV e H2O2/UV/O3 via rea??o direta (oz?nio molecular), indireta (radical hidroxila) e mista (O3/HO?) manipulando-se o pH do meio reacional. Essas subst?ncias tem grande resist?ncia aos processos convencionais de tratamento de efluentes e, assim buscam-se ferramentas mais eficientes para a degrada??o desses f?rmacos. A remo??o dos f?rmacos PCT e DPN nas amostras tratadas com os diferentes POA foi monitorada utilizando a t?cnica cromatografia l?quida de alta efici?ncia (HPLC). A quantidade total de compostos arom?ticos e o grau de mineraliza??o da mat?ria org?nica dissolvida foram avaliados por meio dos par?metros UV (254 nm), Demanda Qu?mica de Oxig?nio (DQO) e de Carbono Org?nico Total (COT). Al?m disso, a susceptibilidade a biodegradabilidade foi avaliada por meio da raz?o da DQO/COT. Os resultados experimentais mostraram que o tempo gasto para a degrada??o depende da natureza do f?rmaco, bem como do pH e do tipo de processo oxidativo. Verificou-se uma elevada percentagem de remo??o (95%) e um percentual moderado de mineraliza??o (35%) para os estudos utilizando os processos O3 (pH 12) e O3/UV. De um modo geral, verificou-se um aumento da biodegradabilidade das amostras tratadas para os diferentes tratamentos oxidativos. No caso dos processos H2O2/UV e H2O2/UV/O3 a remo??o dos f?rmacos foi alta, especialmente no caso do processo H2O2/ UV/O3 onde ap?s 45 min e dose de 200 ppm de per?xido obteve-se ?88% de remo??o dos f?rmacos. No caso do processo H2O2(800ppm)/O3/UV e para o f?rmaco PCT, verificou-se percentagens de remo??o de DQO e COT de 77% e 42%, respectivamente. J? para o f?rmaco DPN, os valores correspondentes obtidos foram de 70% e 68%, respectivamente. Analisando os resultados observou-se que a remo??o da DQO e do COT foi maior para os processos processo H2O2/UV/O3. Por outro lado, a maior remo??o das subst?ncias parentais (PCT e DPN) foi obtida utilizando o processo O3 (pH 12). A partir dos valores das constantes de velocidade em fun??o do pH estimou-se a contribui??o dos processos de oxida??o por via direta e indireta. De um modo geral, o estudo revelou que o uso dos presentes POA e/ou ozoniza??o pode constituir um processo de tratamento alternativo vi?vel para a remo??o/degrada??o dos f?rmacos PCT e DPN presente em ?guas contaminadas. / Disserta??o (Mestrado) ? Programa de P?s-Gradua??o em Qu?mica, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2014. / ABSTRACT The oxidation of synthetic wastewaters containing the drugs Acetaminophen (PCT) and Dipyrone (DPN), which are analgesics of widespread use by the human being and animals, was carried out by means of the O3, O3/UV, H2O2/UV e H2O2/UV/O3 oxidative processes. The ?direct? oxidation process was promoted by action of the O3 (acidic solutions) while in the case of the ?indirect? processes the application of the Advanced Oxidation Processes (AOPs) has permitted the use of the hydroxyl radical (HO?) as the major oxidant. These substances are recalcitrant towards the conventional wastewater treatments and, therefore, the search for an efficient treatment for these effluents is of current interest. The removal of PCT and DPN in the treated samples using the different AOPs was monitored using the high performance liquid chromatography (HPLC) technique. The total amount of aromatics and the degree of mineralization of the dissolved organic matter were evaluated by means of the UV(254 nm) technique and the Chemical Oxygen Demand (COD) and Total Organic Carbon (COT) methods, respectively. In addition, biodegradability susceptibility was evaluated by means of the COD/TOC ratio. The experimental findings showed that the time spent for degradation depends on the nature of the drug, as well as on the pH and the type of the oxidative process. It was verified for the studies using the O3(pH 12) and O3/UV processes a high percentage of removal (95%) and a moderate percentage of mineralization (35%). On the whole, it was verified an increase in the biodegradability of the treated samples for the different oxidative treatments. In the case of the H2O2/UV and H2O2/UV/O3 processes the removal of PCT and DPN was high, especially in the case of the H2O2/UV/O3 where after 45 min and by using a peroxide dosage of 200 ppm a percentage of removal of ?88% was obtained. In the case of the H2O2(800ppm)/UV/O3 process and for PCT, it was verified percentages of removal for COD and COT of 77% and 42%, respectively. Accordingly, the corresponding values obtained for DPN were 70% and 68%, respectively. As a rule, the removal of COD and COT was higher for the H2O2/UV/O3 process. On the contrary, a higher removal (e.g., HPLC) of the parental substances (PCT and DPN) was obtained using the O3 (pH 12) process. In the case of the ozonation the contribution of the direct and indirect oxidation processes was evaluated from the values of the pseudo first-order rate constants obtained in the acidic and alkaline conditions. On the whole, the current study has revealed that the use of the present AOPs and/or ozonation can constitute a viable alternative treatment process for the removal/degradation of the PCT and DPN drugs present in contaminated waters.

Oils of many plant species have been investigated for being precursor material for the production of biodiesel. Maca?ba (Acrocomia aculeata) is a native palm in Brazil, whose fruit has a significant proportion of oil, with real potential for the industrial production of biodiesel. There is a wide range of issues still to be systematically explored, in order to achieve an adequate view of the rational crop management of the palm, extraction and processing of the oil for the production and the commercial storage of biodiesel. The chemical behavior of the fatty acid methyl esters from the maca?ba oil and the leaching of metal elements put directly in contact with carbon steels used in the construction of tanks and pipelines are the main focus of the present experimental work. The composition in methyl esters of the biodiesel obtained from the transesterification reaction of triacylglycerols of the maca?ba fruit kernel oil with methanol, in direct contact with the galvanized and non-galvanized carbon steels ASTM A283 grade C and API X65. The M?ssbauer spectroscopy results obtained in this work also showed that the contact with the maca?ba biodiesel gives protection to the non - galvanized steels against the oxidative corrosion in direct contact with air. Also the formation of iron-bearing chemical species, namely magnetite (Fe3O4) and w?stite (Fe1-xO), on the surface of the non-galvanized bar steels when in direct contact with air; no such iron oxide was detected on the steel bars used in the biodiesel, by monitoring up to 105 days of storage. But the corrosion rates are low, according to the NACE-RP0775, Standard Recommended Practice: Preparation, Installation, Analysis, and Interpretation of Corrosion Coupons in Oilfield Operations. These results allow better evaluate and more adequately specify conditions of storage and transportation of biodiesel obtained from the maca?ba oil. The biodiesel of the maca?ba almond oil has 63.44 mass% of esters of saturated fatty acids. A condition that ensures relatively high oxidative stability of the fuel, even in contact (in the present experiment, by immersion) with API or ASTM carbon steel, galvanized or not.

Além disso, o trabalho discute a Literatura Infantil e Juvenil esclarecendo por que este autor agrada este público leitor. Após isso, propõe-se uma tradução para dois de seus textos: The Doubtful Guest (1980g) e The Gashlycrumb Tinies (1980h), dois livros que se encontram na coletânea Amphigorey (1980a). Ambas as obras são poesias com rimas emparelhadas, com um ritmo que não pode ser ignorado. A tradução dos textos é realizada em três principais etapas. A primeira se preocupa apenas com o conteúdo semântico, enquanto a segunda propõe uma poesia em versos livres e a terceira uma tradução que tenta recriar as poesias buscando manter forma e conteúdo. As três fases são partes do processo tradutório das obras, que é descrito no quarto capítulo.<br> / Abstract : The aim of this research is to present the writer and illustrator Edward Gorey (1925-2000) and to discuss about some interesting characteristics of his books, as the Nonsense genre, some Surrealist and Dadaist characteristics, and the importance of his drawings in his books. Furthermore, it discusses about children´s literature in order to explain why these readers like his books. In addition, it brings a translation for two of his books: The Doubtful Guest (1980g) and The Gashlycrumb Tinies (1980h), both of them are in his book Amphigorey (1980a). Both of the books chosen are in verses that have rhyming couplets and have important rhythm. The translation of the books have three stages. The first stage is the translation of the words without worrying about rhymes or verses. The second stage of the translation is a poem made of free verses, and the third stage of the translation results in a poem that worries about the rhythm, the verses, the rhyme and the meaning of the words. The three stages are part of the translating process of the books and they are described in the fourth chapter of the research.
