Our research aimed to analyze whether the current selection process of students conducted by the Campus Vitoria de Santo Ant?o constitutes a policy of inclusion. In recent years, initiatives are being taken to allow access to education and ensure the permanence at school of the poor and offering them a quality education from early childhood education to higher education. The Campus Vitoria de Santo Ant?o of the Federal Institute of Pernambuco proposed, in 2006, changes in its selection process with the intention of promoting social inclusion on the new directions taken by the Vocational Education, to democratize access to their courses and bring inside the rural population for which the Agrotechnical Schools were created. We used as instruments for data collection interviews, questionnaires, surveys of documentary and bibliography material, with the main subject of the graduates of that course of Agricultural Campus in 2010 in order to identify the reasons that led them to choose the school and intended course. We interviewed, too, the servers involved in the various selection processes to understand how was being understood and applied the concept of social inclusion in different stages of the selection process of the school. We also performed a reading of literature pertinent to the dissertation topic, so we can contextualize our work and theoretical basis. The results showed us that are possible make a different selection process of the traditional college entrance exam, and thus enable the entry of young people from disadvantaged sections, giving them access to quality education and ensuring their stay in school. We recognize that the initiative and management support are essential to a proposal for a paradigm shift in access to quality public education, that is not based only on the valuation of purely cognitive aspects. The testimony of servers and show students the positive view that the school community have the selection process, while they show suggestions and comments for its improvement. We expect, with this work, collaborate on understanding the issues related to the selection test theme for admission of students in public schools, at a time of redefinition, the lack of extensive discussion and consensus of the effectiveness of these processes in the democratization of access and social inclusion. We believe that even without the intention to generalization, the results obtained in this study may serve as a reference for other education institutions looking to implement policies and actions for Social Inclusion / O presente trabalho ? resultado de uma pesquisa realizada no Campus Vit?ria de Santo Ant?o do Instituto Federal de Educa??o, Ci?ncia e Tecnologia de Pernambuco. Nossa pesquisa teve como objetivo analisar se o atual processo de sele??o de alunos realizado pelo Campus Vit?ria de Santo Ant?o se constitui uma Pol?tica de Inclus?o. Nos ?ltimos anos, iniciativas est?o sendo tomadas no sentido de permitir o acesso ? educa??o e garantir a perman?ncia na escola das camadas mais carentes, oferecendo-lhes um ensino de qualidade desde a educa??o infantil ao ensino superior. O Campus Vit?ria de Santo Ant?o do Instituto Federal de Pernambuco prop?s, em 2006, mudan?as no seu Processo Seletivo com a inten??o de promover a inclus?o social diante dos novos rumos assumidos pela Educa??o Profissional, no sentido de democratizar o acesso aos seus cursos e trazer para dentro dela a popula??o rural para a qual as Escolas Agrot?cnicas foram criadas. Utilizamos como instrumentos de coleta de dados entrevistas, question?rios, levantamentos de material documental e bibliogr?fico, tendo como principais sujeitos os concluintes do curso de Agropecu?ria do referido Campus no ano de 2010, a fim de identificar as raz?es que os levaram a escolher a escola e o curso pretendido. Entrevistamos, tamb?m, os servidores envolvidos nos diversos processos seletivos para compreender como estava sendo entendido e aplicado o conceito de Inclus?o social nas fases distintas do Processo seletivo da escola. Realizamos, ainda, leitura de bibliografia pertinente ao tema da disserta??o, para que pud?ssemos contextualizar e embasar teoricamente nosso trabalho. Os resultados nos mostraram que ? poss?vel realizar um processo seletivo diferenciado do tradicional vestibular, e assim possibilitar o ingresso de jovens das camadas menos favorecidas, proporcionando-lhes o acesso ao ensino de qualidade, e garantindo sua perman?ncia na escola. Reconhecemos que a iniciativa e o apoio da gest?o s?o essenciais para uma proposta de mudan?a de paradigma no acesso ao ensino p?blico de qualidade, que n?o esteja pautado apenas na valoriza??o de aspectos meramente cognitivos. Os depoimentos de servidores e alunos mostram a vis?o positiva que a comunidade escolar tem do processo seletivo, ao tempo que apresentam sugest?es e cr?ticas para o seu aperfei?oamento. Esperamos, com este trabalho, colaborar na elucida??o de quest?es relativas ? tem?tica exame de sele??o para ingresso de alunos nas escolas p?blicas, em um momento de redefini??o, ampla discuss?o e falta de consenso da efic?cia desses processos na democratiza??o do acesso e na inclus?o social. Acreditamos que, mesmo sem a pretens?o de generaliza??o, os resultados obtidos nessa pesquisa poder?o servir de refer?ncia para outras Institui??es de ensino que buscam implementar pol?ticas e a??es de Inclus?o Social

The chemical communication sign may have a highest importance in the space orientation and sexual behavior displayed by the chelonian during the reproductive period. There are not histological and morphological studies of the Brazilian chelonian species tegumental appendices, like Hydromedusa maximiliani and Phrynops geoffroanus. So, the actual study had the goal to describe and compare morphologically and histologically the tegumental appendices from two Brazilian tortoise species which belong to the Chelidae family. For this study, it was used adult specimens from the Cole??o Herpetol?gica do Departamento de Zoologia da Universidade Federal de Juiz de Fora of H. maximiliani (2 males and 2 females) and P. geoffroanus (4 males and 4 females), totalizing 12 specimens. The analysis of the external surface neck, head and chin region was done. The animals were dissected using stereoscopic microscope to take samples out of the epidermis and dermis from the neck and head region. To the microscopic analysis, it was done the routine techniques that are used in the histological studies. In P. geoffroanus, the keratinized epidermis layer is thicker when compared to the same epidermis layer of H. maximiliani. It was observed that in P. geoffroanus and H. maximiliani these regions may present epidermis invaginations with the detachments of the most external keratin layers. The histological and histochemical study done in the epidermis cuts of the specimens H. maximiliani and P. geoffroanus haven?t evidenced the presence of submandibular gland. The PAS method hasn?t shown the presence of neutral mucopolysaccharides in this submandibular gland, which are products part of the secretions produced by the exocrine glands. In this study, it was observed that the dewlap presented in P. geoffroanus are cylindrical tegumental appendices presented in the mandibular symphysis posterior region, which occurs in pairs, constituting of epidermis and dermis, and with a great concentration of nervous terminations. In the actual study, the P. geoffroanus specimens macroscopically presented conical shape tubers, rarely pointed and also with verrucous shape, visible in the dorsal and lateral region, from the anterior part up to the posterior part of the neck, not presented in the ventral region of the neck, which presents slots, grooves and depressions in the epidermis. In the actual study, it wasn?t observed morphological and histological differences regarding the tubers when compared by gender. In H. maximiliani the tubers are irregularly distributed in the lateral and dorsal regions of the neck, being absent in the region of the head and in the ventral region of the neck. They present pointed and tray shape, different from what was observed in the P. geoffroanus specimens. The tubers presented in the two studied species are different in macroscopic terms, but all of them present a random disposition and are also absent in the ventral region of the neck. For the two types of tegumental annexes (tubers, dewlap) analyzed in this study, it was verified that there are not differences between the genders. / Os quel?nios empregam sinais t?teis, visuais, olfativos e qu?micos durante as intera??es sociais. A comunica??o usando sinais qu?micos pode ter uma import?ncia maior na orienta??o espacial e comportamento sexual exibidos pelos quel?nios durante o per?odo reprodutivo. S?o inexistentes os estudos histol?gicos e morfol?gicos dos ap?ndices tegument?rios das esp?cies de quel?nios brasileiros, como Hydromedusa maximiliani e Phrynops geoffroanus. Dessa forma, o presente estudo teve como objetivos descrever e comparar morfol?gica e histologicamente os anexos tegumentares de duas esp?cies brasileiras de c?gados pertencentes ? Fam?lia Chelidae. Para esse estudo foram utilizados esp?cimes adultos de H. maximiliani (dois machos e duas f?meas) e P. geoffroanus (quatro machos e quatro f?meas), totalizando 12 esp?cimes, provenientes da Cole??o Herpetol?gica do Departamento de Zoologia da Universidade Federal de Juiz de Fora Foi realizada a an?lise da superf?cie externa da regi?o do pesco?o, cabe?a e da regi?o mentoniana. Os animais foram dissecados sob microsc?pio estereosc?pico para retirada de amostras da epiderme e derme das regi?es da cabe?a e pesco?o. Para an?lise microsc?pica foram realizados as t?cnicas de rotina utilizadas nos estudos de histologia. Em P. geoffroanus a camada queratinizada da epiderme ? mais espessa quando comparada com a mesma camada na epiderme de H. maximiliani. Foi observado em P. geoffroanus e H. maximiliani que essas regi?es podem apresentar invagina??es da epiderme com o desprendimento das camadas mais externas de queratina. O estudo histol?gico e histoqu?mico realizado nos cortes da epiderme de ambas esp?cies de, n?o evidenciou a presen?a da gl?ndula submandibular. O m?todo de PAS n?o mostrou a presen?a de mucopolissacar?deos neutros nessa regi?o submandibular, que s?o produtos que fazem parte das secre??es produzidas por gl?ndulas ex?crinas. Nesse estudo observou-se que as barbelas presentes em P. geoffroanus s?o ap?ndices tegumentares cil?ndricos presentes na regi?o posterior da s?nfise mandibular, que ocorrem aos pares, constituindo-se de epiderme e derme, e com grande concentra??o de termina??es nervosas. No presente estudo, os esp?cimes de P. geoffroanus macroscopicamente apresentaram tub?rculos de forma c?nica, raramente pontiagudos, e tamb?m de formato verrucoso, vis?veis na regi?o dorsal e lateral desde a parte anterior at? a parte posterior do pesco?o, n?o estando presentes na regi?o ventral do pesco?o, que apresenta ranhuras, estrias e depress?es da epiderme. No presente estudo n?o foram observadas diferen?as morfol?gicas e histol?gicas em rela??o aos tub?rculos quando comparados por sexo. Em H. maximiliani os tub?rculos est?o distribu?dos de forma irregular nas regi?es laterais e dorsais do pesco?o, estando ausentes na regi?o da cabe?a e na regi?o ventral do pesco?o. Apresentam formato pontiagudo e de tabuleiro, diferente do que foi observado nos esp?cimes de P. geoffroanus. Os tub?rculos presentes nas duas esp?cies estudadas s?o diferentes em termos macrosc?picos, mas todos apresentam uma disposi??o aleat?ria e est?o tamb?m ausentes na regi?o ventral do pesco?o. Para os dois tipos de anexos do tegumento (tub?rculos, barbelas) analisados nesse estudo, verificou-se que n?o existe diferen?a entre os sexos.

On the other hand, the correct planning of land use, avoiding farming lands with high erosion risk, could minimize the erosion process without compromising food security. The aim of this study was to evaluate erosion risk and soil losses in a watershed using remote sensing and GIS, coupled with temporal evolution of vegetation cover and occupation of land, in areas of the municipalities of Paty do Alferes and Miguel Pereira, Rio de Janeiro State. For this, the RUSLE (Revised Universal Soil Loss Equation) was used as model to predict soil loss, combined with remote sensing data and the derived NDVI (Normalized Difference Vegetation Index), to determine the soil coverage in a GIS (Geographic Information System). Satellite images used in this research included: TM sensor of Landsat-5, ETM+ of Landsat-7, CCD of CBERS-2, and CCD and HRC from CBERS 2B, obtained for the study period. The processed remotely sensed data and the geographic information system, integrated with models for predicting soil loss, showed good performance for environmental analysis. The use of NDVI was a suitable tool for determining the vegetation coverage, to be applied in soil loss prediction models. The soil losses and erosion risks were strongly associated with characteristics of relief, and they can be used for planning land usage and occupation, in urban and rural areas. More studies should be conducted linking GIS, erosion prediction models, and remote sensing data in order to better predict the occurrence of environmental disasters, also to create databases about soil?s response in relation to different causative erosional agents. / A eros?o do solo ? um problema crescente no mundo atual, em praticamente todos os continentes, que se deve ao crescimento da demanda por alimentos, ao mau uso dos solos e a necessidade de produ??o de fibras e combust?veis. Por outro lado, o planejamento correto do uso e cobertura dos solos evitando utilizar ?reas para a agricultura que tenham alto risco de eros?o e alto potencial natural de eros?o pode minimizar o processo, sem comprometer a seguran?a alimentar. O objetivo deste trabalho foi avaliar o risco de eros?o e a perda de solo em uma bacia hidrogr?fica utilizando t?cnicas de sensoriamento remoto e SIG, associados ? evolu??o temporal dos ?ndices de cobertura e ocupa??o do solo, em ?reas nos munic?pios de Paty do Alferes e Miguel Pereira, Estado do Rio de Janeiro. Para isso, utilizou-se o modelo de predi??o de perdas de solos, no caso a RUSLE (?Revised Universal Soil Loss Equation?), associado a t?cnica de sensoriamento remoto integrada ao ?ndice de vegeta??o NDVI (?Normalized Difference Vegetation Index?) para determinar a cobertura dos solos em um SIG (Sistema de Informa??o Geogr?fica). Para tal, foram utilizadas imagens de sat?lite dos sensores TM Landsat-5, ETM+ Landsat-7 CCD CBERS-2 e CCD e HRC do CBERS 2B coletadas no per?odo considerado. Os dados de sensoriamento remoto e do sistema de informa??es geogr?ficas integrados a modelos de predi??o de perdas de solos caracterizaramse como importantes instrumentos na an?lise do meio ambiente. A utiliza??o de NDVI constitui-se em ferramenta adequada para a determina??o da cobertura, para aplica??o em modelos de predi??o de perda de solo. As perdas de solo, o potencial natural de eros?o e o risco mostraram forte rela??o com as caracter?sticas do relevo, podendo ser utilizados no planejamento do uso e ocupa??o do solo em ?reas urbana e rural. Mais estudos devem ser realizados associando SIG, modelos de predi??o de eros?o e t?cnicas de sensoriamento remoto no sentido de melhor prever a ocorr?ncia de desastres ambientais, tamb?m para criar bancos de informa??es sobre o comportamento dos solos em rela??o aos diversos agentes causadores do processo erosivo.

Although many researches will be developed with Sindhi breed animals, such experiments are focused mainly on productive aspects, and researches involving the reproductive tract are still scarce in the Sindhi Zebu breed. Thus, the aim of this study was to evaluate the reproductive parameters of Sindhi cows, aiming to improve the efficiency of FTAI protocols in this breed. To this end, sixteen Sindhi cows with body condition score between 3,0 and 4,0 (scale from 1 to 5) were divided into two evaluation groups: In group I (BE protocol, n=8) animals received on day 0 an intravaginal P4 device and an application of 2mg of estradiol benzoate. On day 8 the device was removed and applied 10mg of Dinoprost (PGF2?), and on day 9, applied 1 mg of estradiol benzoate, and were fixed-time artificial inseminated 36 h later; in group II (BE + eCG protocol, n=8) animals were submitted through same treatment, and on day 8 were applied 400 IU of eCG. From day 0 for both treatments, the animals were examined daily by trans-rectal ultrasound device equipped with a 7,5MHz linear transducer (CHISON? D600 VET). This evaluation was performed up to ovulation. At each assessment, the largest follicles of each day (?4 mm) were measured. It used analysis of variance (ANOVA) to evaluate the results, and the means determined by Tukey test, with significance level of 5%. For data analysis, it was observed that there was no statistical difference (P>0.05) for groups I (Treatment I: no eCG) and II (Treatment II: 400 IU eCG) concerning to emergence of follicular wave, 4.5 ? 1.4 and 3.8 ? 0.3 days; interval between the emergence of the wave and ovulation, 5.8 ? 1.4 and 7.1 ? 0.3 days; interval between the emergence of the wave and implant removal, 3,5 ? 1,4 and 4,1 ? 0,3; interval between implant removal and ovulation, 74.0 ? 11.8 and 82.5 ? 4.2 hours; diameter of the dominant follicle (DF) at the time of implant removal, 7.5 ? 2.5 and 6.6 ? 1.5 mm; diameter maximum of DF, 10.47 ? 8.85 and 3.7 ? 1.2 mm; growth rate of the DF, 0.90 ? 0.83 and 0.7 ? 0.6 mm/day and ovulation rate, 75 % (6/8) and 100% (8/8), respectively. Regarding to pregnancy rate, it was observed that there was statistical difference (P<0.05) between protocols I and II (0% and 50%, respectively). Therefore, we conclude that the use of eCG in Sindhi breed cows was not effective in improving the reproductive parameters examined, perhaps because the cows are cycling at the beginning of treatment and had good body condition score during the experiment. On the other hand, there was an increase in pregnancy rate with the use of eCG, indicating that this gonadotropin may be a useful tool in FTAI protocols in this breed. / A ra?a Sindi apresenta excelente adaptabilidade ?s condi??es adversas de manejo e clima, e boa capacidade de produ??o de leite. Embora muitas pesquisas venham sendo desenvolvidas com animais desta ra?a, tais experimentos se concentram predominantemente em aspectos produtivos, pesquisas envolvendo a ?rea reprodutiva ainda s?o escassas na ra?a Sindi. Portanto, o objetivo deste trabalho foi avaliar os par?metros reprodutivos de vacas Sindi, buscando melhorar a efici?ncia dos protocolos de IATF nesta ra?a. Para tanto, 16 vacas da ra?a Sindi, com escore de condi??o corporal entre 3,0 e 4,0 (escala de 1,0 a 5,0) foram divididas em dois grupos de avalia??o: no grupo I (esquema BE, n=8), os animais receberam no dia 0 um implante intravaginal impregnado com 1,9g de progest?geno e uma aplica??o de 2mg de benzoato de estradiol. No dia 8 o implante vaginal foi removido, sendo aplicados 10mg de Dinoprost (PGF2?) e, no dia 9, aplicado 1mg de benzoato de estradiol, sendo realizada a IATF 36 horas ap?s; no grupo II (esquema BE + eCG, n=8), os animais passaram pelo mesmo tratamento, sendo que no dia 8 foram aplicadas 400UI de gonadotrofina cori?nica eq?ina (eCG). A partir do dia 0, para os dois tratamentos, os animais foram examinados diariamente por via trans-retal com aparelho de ultrassom (CHISON? D600 VET) equipado com um transdutor linear de 7,5 MHz. Esta avalia??o foi realizada at? o momento da ovula??o. Em cada avalia??o, os maiores fol?culos de cada dia (?4 mm) foram mensurados. Foi utilizada a an?lise de vari?ncia (ANOVA) para avalia??o dos resultados, sendo as m?dias determinadas pelo teste de Tukey, com n?vel de signific?ncia de 5%. Pela an?lise dos dados, observou-se que n?o houve diferen?a estat?stica (P>0,05) para os grupos I e II na emerg?ncia da onda folicular, 4,5 ? 1,4 e 3,8 ? 0,3 dias; no intervalo entre a emerg?ncia da onda e a ovula??o, 5,8 ? 1,4 e 7,1 ? 0,3 dias; no intervalo entre a emerg?ncia da onda e a retirada do implante, 3,5 ? 1,4 e 4,1 ? 0,3; no intervalo entre a retirada do implante e a ovula??o, 74,0 ? 11,8 e 82,5 ? 4,2 horas; no di?metro do fol?culo dominante (FD) na retirada do implante, 7,5 ? 2,5 e 6,6 ? 1,5 mm; no di?metro m?ximo do FD, 10,47 ? 3,7 e 8,85 ? 1,2 mm; na taxa de crescimento do FD, 0,90 ? 0,7 e 0,83 ? 0,6 mm/dia e na taxa de ovula??o, 75% (6/8) e 100% (8/8), respectivamente. Com rela??o ? taxa de prenhez, foi observada diferen?a estat?stica (P<0,05) entre os grupos I e II, sendo 0% (0/8) e 50% (4/8), respectivamente. Portanto, conclui-se que o uso do eCG em f?meas bovinas da ra?a Sindi n?o foi efetivo em melhorar os par?metros reprodutivos analisados, talvez pelo fato das vacas apresentarem bom escore de condi??o corporal durante a realiza??o do experimento. Por outro lado, houve um aumento na taxa de prenhez com o uso do eCG, indicando que este pode ser uma ferramenta ?til em protocolos de IATF nesta ra?a.

All experiments were conducted at Embrapa Agrobiology. Firstly, the experiments were performed under controlled conditions in a greenhouse using soil layer of 0-10 cm of a haplic planosol. In the first experiment, the plastic trays were used as experimental units for evaluation of losses due to volatilization chambers with the aid of semi-open static free (SALE). Commercial urea was applied (UC), urea + KCl (UK), humic acid + urea (UH), urea + zeolitic sandstone (UZ) and urea + gypsum (UG) in two conditions of pH (5.4 and 6,5). Secondly, the other experiment was conducted using plastic pots containing the same soil samples as experimental units where they were planted three plants of Brachiaria decumbens. In this case, fertilizers were enriched with 15N, in two pH conditions too (pH 5,4 and 6,5). Treatments UZ and UK were more efficient in retaining N in the soil than the UC, with smaller losses through volatilization of NH3-N, and 20,2 and 15,8% on condition of lime and 22 and 17,2% when Liming did not occur, respectively. The UK fertilizer and UG showed overall increase of about 149 and 146% on dry biomass production at the end of the cycle on condition of pH 5,4. At pH 6,5 UG fertilizer showed yield increases of 149,3%. The accumulation of N in the plant and was 279,2 and 270,3 mg N.vaso-1 when no lime was applied to the UK and UG treatments, respectively, and the limed, 207.4 and 200,6 mg N. vaso-1 for the treatments UG and UH, respectively. Treatments UZ and UK had the highest recovery of applied N by plants, with values of 65,5 and 61,9% without lime, 60,2 and 45,7% with lime, respectively. Thirdly, other experiment was conducted at the experimental field at Embrapa Agrobiology in order to quantify the PNV, N2O emissions and efficiency of nitrogen fertilizer use (NFUE) slow-release by a corn crop on N balance Treatments consisted of field application of nitrogen fertilizers in coverage along the rows and a control treatment. Emissions of N2O were evaluated using static chambers closed. Was used fertilizers enriched with 15N in little plots for the assessment of NFUE. The treatments UZ and UK reduced the losses of N-NH3 by volatilization in approximately 18 and 14%, respectively. These losses corresponded to 32,3 and 35,7% of total N applied to soil. For N2O emissions the UK treatment showed the largest emission of N2O losses reaching values of 2.02 kgN.ha-1. The highest yield of grain were obtained by treatments that UG and UZ had a better response of grain production reaching values of 9666 and 9940 kg ha-1 respectively. To NFUE treatment UZ showed the highest values of N recovered reaching 67% of the total N applied system soil plant. / O trabalho objetivou avaliar a efici?ncia agron?mica de fertilizantes nitrogenados de libera??o lenta baseados no uso da ureia, quantificando suas perdas por volatiliza??o de NNH3 (PNV), emiss?o de N2O e a recupera??o do N-fertilizante aplicado em cobertura em compara??o com a ureia comercial na cultura de milho. Todos os esperimentos foram conduzidos na Embrapa Agrobiologia. Os primeiros experimentos foram realizados em condi??es controladas em casa de vegeta??o, utilizando solo da camada de 0-10 cm de um Planossolo H?plico. No primeiro experimento foram usadas bandejas pl?sticas como unidades experimentais para avalia??o das perdas por volatiliza??o com aux?lio de c?maras semi-aberta livre est?tica (SALE). Aplicou-se ureia comercial (UC), ureia + KCl (UK), ureia + ?cido h?mico (UH), ureia +arenito zeol?tico (UZ) e ureia +gesso agr?cola (UG) em duas condi??es de pH (5,4 e 6,5). O outro experimento utilizou vasos pl?sticos contendo amostras do mesmo solo como unidades experimentais onde foram plantados 3 plantas de Brachiaria decumbens. Neste caso os fertilizantes foram enriquecidos com 15N, tamb?m em duas condi??es de pH (pH 5,4 e 6,5). Os tratamentos UZ e UK foram mais eficientes na reten??o do N no solo do que a UC, apresentando menores perdas por volatiliza??o de N-NH3 de 20,2 e 15,8% sob condi??o de calagem e 22 e 17,2% quando sem calagem, respectivamente. Os fertilizantes UK e UG apresentaram aumento total de aproximadamente 149 e 146% na produ??o de biomassa seca ao final do ciclo da cultura em condi??o de pH 5,4. Em pH 6,5 o fertilizante UG apresentou aumento de rendimento de 149,3%. O ac?mulo de N na planta foi de 279,2 e 270,3 mg N.vaso-1 quando n?o foi aplicado calagem para os tratamentos UK e UG, respectivamente e quando com calagem, 207,4 e 200,6 mg N.vaso-1 para os tratamentos UG e UH, respectivamente. Os tratamentos UZ e UK apresentaram maior recupera??o pelas plantas do N aplicado, com valores de 65,5 e 61,9% sem calagem e 60,2 e 45,7% com calagem, respectivamente. O outro experimento foi realizado no campo na ?rea experimental da Embrapa Agrobiologia com objetivo de quantificar as perdas por volatilza??o de am?nio, as emiss?es de N2O e a efici?ncia do uso de fertilizantes nitrogenados (EUFN) de libera??o lenta pela cultura de milho, no balan?o de N. Os tratamentos consistiram da aplica??o no campo em cobertura dos fertilizantes nitrogenados ao lado da linha de plantio e um tratamento controle. As emiss?es de N2O foram avaliadas utilizando-se c?maras est?ticas fechadas. Foi utilizado fertilizantes enriquecidos com 15N em microparcelas para a avalia??o da EUFN. Os tratamentos UZ e UK reduziram as perdas de N-NH3 por volatiliza??o em aproximadamente 18 e 14%, respectivamente. Estas perdas corresponderam a 32,3 e 35,7% do total de N aplicado no solo. Para as emiss?es de N2O o tratamento UK foi o que apresentou maiores perdas por emiss?o de N2O atingindo valores de 2,02 kg N.ha-1. As maiores produtividades de gr?o foram obtidas pelos tratamentos UG e UZ que apresentaram melhor resposta de produ??o de gr?os atingindo valores de 9.666 e 9.940 kg.ha-1, respectivamente. Para EUFN o tratamento UZ apresentou o maior valor de N recuperado chegando a 67% do total do N aplicado no sistema solo-planta.

There was significant difference (P < 0,05) in the natural matter consumption; however, when an adjustment for dry matter, the difference did not persist. It was observed differentiates (P < 0,05) in the times of ingestion, rumination, leisure and other activities. The animals that consumed mulberry leaves spent more time ingesting, ruminating and in leisure than the animals that consumed the other foods and for that they spent less time with other activities. There was not influence (P > 0,05) of the food type on the tax of mastication of the animals. There was significant difference (P < 0,01) in the coefficients of digestibility of the dry matter and of the fractions of the fiber (P < 0,05). Was ended that the consumption of matter drought did not differ among the treatments, although the animals that consumed mulberry leaves have spent more time in the ingestion and rumination of that food, suggesting possible inherent differences to the cellular wall of this bulky one interfering in these varied. The brown brocket deer used in this study, they were shown relatively efficient in the digestion of the fiber, when this was used as partial ingredient of the diet, and the animals that consumed mulberry leaves and perennial soybean, obtained the largest digestibility coefficients. / Entre Julho e Agosto de 2005 nove veados-catingueiro (Mazama gouazoubira), foram alojados em baias individuais, distribu?dos em um delineamento experimental inteiramente casualizado, com tr?s tratamentos e tr?s repeti??es, com o objetivo de avaliar o consumo e a digestibilidade de tr?s alimentos: alfafa (Medicago sativa), folhas de amoreira (Morus Alba) e soja perene (Neonotonia Wightii), bem como o comportamento ingestivo dos animais em rela??o ?s dietas a que foram submetidos, sendo monitorados durante 24 horas, em intervalos regulares de cinco minutos, determinando-se as atividades de alimenta??o, rumina??o, consumo de ?gua, ?cio e outras atividades. Houve diferen?a significativa (P < 0,05) no consumo de mat?ria natural, entretanto, quando se efetuou um ajuste para mat?ria seca dos alimentos, a diferen?a n?o persistiu. Observou-se diferen?a (P < 0,05) nos tempos de ingest?o, rumina??o, ?cio e outras atividades. Os animais que consumiram folhas de amoreira, gastaram mais tempo ingerindo, ruminando e em ?cio do que os animais que consumiram os outros alimentos e por isso gastaram menos tempo com outras atividades. N?o houve influ?ncia (P > 0,05) do tipo de alimento sobre a taxa de mastiga??o dos animais. Houve diferen?a significativa (P < 0,01) nos coeficientes de digestibilidade da mat?ria seca e das fra??es da fibra (P < 0,05). Concluiu-se que o consumo de mat?ria seca n?o diferiu entre os tratamentos, embora os animais que consumiram folhas de amoreira tenham gastado mais tempo na ingest?o e rumina??o desse alimento, sugerindo poss?veis diferen?as inerentes ? parede celular deste volumoso interferindo nestas vari?veis. Os veados-catingueiros utilizados neste estudo, mostraram-se relativamente eficientes na digest?o da fibra, quando esta foi utilizada como ingrediente parcial da dieta, sendo que os animais que consumiram folhas de amoreira e soja perene, obtiveram os maiores coeficientes de digestibilidade.

The analysis explores the context of creation of local parties ? liberals and conservatives ? through three ways: the press, the Provincial Assembly and the local political elite. Thus, this study relies on the analysis of various political journals of the period, which were reached the main ideas, projects and policy languages of each party. From the information obtained was developing the profile of the local intellectual elite: the writers. We also observed in this work the analysis of discourses and conflicts that emerge in the Provincial Assembly from 1860 to 1880, addressing the political vocabulary of deputies, and exposure of their proposals facing the political unrest in the Court. Finally, in order to get as much information as possible, an analysis was made of the profile of provincial deputies, focusing on aspects such as education level, academic training, employment and place of birth. The study demonstrated that the province of the Esp?rito Santo has a different demeanor from other provinces when compared to the date of creation of the two major parties in the rest of the Empire. In addition, the province shows after 1860, new political practices and a political vocabulary permeated by new ideas that coming to the province from the new composition of the political and intellectual elite. / Este trabalho tem como objeto principal a din?mica pol?tica da prov?ncia do Esp?rito Santo a partir das transforma??es que emergem ap?s 1860, per?odo em que ocorre uma transforma??o dos grupos pol?ticos pessoais para os verdadeiros partidos pol?ticos de cunho ideol?gico. A an?lise aborda o contexto de cria??o dos partidos locais ? liberais e conservadores- por meio de tr?s formas: a imprensa, a Assembleia Provincial e a elite pol?tica local. Desta forma, este estudo conta com a an?lise de diversos jornais pol?ticos do per?odo, pelos quais foram levantadas as principais ideias, projetos e linguagens pol?ticas de cada partido. A partir dos dados obtidos foi elaborando o perfil da elite intelectual local, ou seja, os redatores. Tamb?m se verifica nesta disserta??o a an?lise dos discursos e conflitos que emergem na Assembleia Provincial entre 1860 e 1880, abordando o vocabul?rio pol?tico dos deputados e a exposi??o de suas propostas diante das agita??es pol?ticas que eram vislumbradas na Corte. Por fim, com a finalidade de levantar o maior n?mero poss?vel de informa??es, foi feita uma an?lise do perfil dos deputados provinciais, concentrando-se em dados como escolaridade, forma??o, ocupa??o e local de nascimento. O estudo demonstrou que a prov?ncia do Esp?rito Santo apresenta um comportamento diferente das demais prov?ncias quando se compara com a data de cria??o dos dois grandes partidos no restante do Imp?rio. Al?m disso, a prov?ncia apresentou, ap?s 1860, novas pr?ticas pol?ticas e um vocabul?rio pol?tico permeado por novas ideias que chegam ? prov?ncia a partir da nova composi??o da elite pol?tica e intelectual

When used in the extraction, enables higher purity of the obtained starch. The starch-the-air yam has physical characteristics desirable for applications such as thickening agent or disintegrating tablet formulations, for example, however, this extraction is hindered by the presence starch mucilage this tubercle. The aim of this study was to review the effect of ultrasound on the extraction and modification of several starches, evaluate their use in starch extraction of yam and its impact on characteristics this starch. After evaluating the chemical composition of tubers, previously washed, peeled and crushed in a blender. Then the crushed sample subjected to ultrasound. Different times (3, 6 to 9 minutes) and amplitudes (12, 40 and 68%) were evaluated by the Box Benker experimental design, furthermore evaluated the control treatment (0% amplitude) and ?T6? (15 minutes, 70% amplitude), totaling 7 treatments (T1, T2, T3, T4, T5, T6 and control). After sonication, the suspension was filtered and the extraction continued by successive washings, centrifugation and drying in an oven. After evaluating the performance of the extraction, the different treatments were characterized by analysis of chemical composition, instrumental analysis of color, scanning electron microscopy, optical microscopy, particle size, pattern of crystallinity, swelling power and solubility, paste clarity, paste properties and thermal properties and absolute density. There was increase in yield of 29,85% (control) to 32,09%, when used longer time and amplitude (15 min and 70% amplitude). The ultrasound caused damage to the surface of starch and reduced starch crystallinity peak, characterized as type B. Additionally, increased swelling power and consequently the paste viscosity of some treatments. However, 15 minutes, 70% amplitude (T6), reduced the swelling power, the paste viscosity and paste clarity and increased the setback. Therefore, despite the small increase in yield, when used ultrasound during extraction, damage was caused in the structure of starch, as well as changes in its physical and chemical characteristics / Dentre as diferentes possibilidades de utiliza??o na ind?stria de alimentos, o ultrassom pode ser considerado uma alternativa para substituir ou reduzir a utiliza??o de subst?ncias qu?micas em processos de extra??o ou modifica??o de amidos. Quando utilizado na extra??o, possibilita maior pureza do amido obtido. O amido de car?-do-ar possui caracter?sticas f?sicas desej?veis para aplica??es como agente espessante ou desintegrante em formula??es de comprimidos, por exemplo. No entanto, a extra??o desse amido ? dificultada pela presen?a de mucilagem nesse tub?rculo. O objetivo do presente estudo foi revisar o efeito do ultrassom na extra??o e modifica??o de diversos amidos, como milho, arroz, mandioca, batata, entre outros, avaliar sua utiliza??o na extra??o do amido de car?-do-ar e seu impacto sobre as caracter?sticas desse amido. Ap?s avaliar a composi??o centesimal do car?-do-ar, o mesmo foi lavado, descascados e triturados em liquidificador. Em seguida a amostra triturada foi submetida ao ultrassom. Diferentes tempos (3, 6 e 9 minutos) e amplitudes (12, 40 e 68%) foram avaliados por meio do planejamento experimental Box Benker. Al?m desses foram avaliados os tratamentos controle (0% amplitude) e T6 (15 minutos, 70% amplitude), totalizando 7 tratamentos (T1, T2, T3, T4, T5, T6 e controle). A extra??o prosseguiu por meio de filtra??o, lavagens sucessivas, centrifuga??o e secagem em estufa. Ap?s avaliar o rendimento da extra??o, os diferentes tratamentos foram caracterizados por meio das an?lises de composi??o centesimal, an?lise instrumental de cor, poder de inchamento e solubilidade, claridade de pasta, determina??o das propriedades t?rmicas e propriedades de pasta, padr?o de cristalinidade, microscopia eletr?nica de varredura, microscopia ?ptica, determina??o do tamanho de part?cula e densidade absoluta do amido. Houve aumento do rendimento de 29,85% (controle) para 32,09%, quando utilizado o maior tempo e amplitude (15 min e 70% amplitude). O ultrassom provocou danos na superf?cie do amido e reduziu os picos de cristalinidade do amido, caracterizados como tipo B. Al?m disso, aumentou o poder de inchamento e consequentemente a viscosidade de pasta de alguns tratamentos. No entanto, 15 minutos e 70% de amplitude (T6), do tratamento com ultrassom, reduziu o poder de inchamento, a viscosidade de pasta e a claridade de pasta e aumentou a tend?ncia ? retrograda??o. Dessa forma, apesar do pequeno aumento do rendimento quando utilizado o ultrassom durante a extra??o, danos foram provocados na estrutura desse amido, assim como altera??es das suas caracter?sticas f?sico-qu?micas.

The humpback whale voalizations were identified and characterized in order to structurate the first data bank of sounds of marine mammals of the Southwestern Atlantic. It was noted the importance of these subunits because they have a degree of small variation, assisting in the identification of the species for the Autonomic Passive Acoustic Monitoring System (MAPA). Records of vocalizations of whales were conducted by the Humpback Whale Institute team (IBJ), between 2006 and 2013, in the region of Abrolhos, Bahia State, Brazil. They held seven readings of the subunits through the Raven 1.4 software, by evaluating: (1) High frequency (Hz); (2) Average power (dB); (3) Energy (dB); (4) Center frequency (Hz); (5) Maximum frequency (Hz); (6) Delta Time (s); and (7) Delta frequency (Hz). There were calculated the average, standard deviation, minimum and maximum values. Multivariate analysis of variance with post-hoc test values were performed where p>0.05 did not represent a significant change in the years. In the years 2006, 2007, 2009 and 2011 there was satisfactory quality to perform the analyzes, which corresponded to 14% of total recordings in 4:06:54 hours. The records analyzed were purchased in the months of highest occurrence of humpback. 862 subunits were identified and analyzed. The identified subunits were A, B and C. The subunit A: n= 156(18%), previously found in a feeding area in the northeast of Iceland (2011), Alaska (2012) and in the region of Abrolhos in all years studied. The B subunit: n= 205(24%), occurring in feeding areas of Iceland (2000) and Alaska (2012) and the breeding area in Hawaii (1991). In Abrolhos region they were recorded in all years studied. The C subunit: 501(51%) was previously recorded in the breeding areas of Madagascar (2009), Hawaii (1989 and 1991), Mexico (2006), Australia (2009) and New Caledonia (2010) and in the feeding area Antarctica (2010). Some subunits showed no significant differences in some of the studied years. The subunits are preserved over the years especially in following parameters: high frequency, center frequency, maximum frequency, delta time and the delta frequency. The parameter delta time has also shown more uniform average and standard deviation, indicating that this should be used as a differentiating character in the analysis of humpback sound emissions. The C subunit had a wide geographic distribution, mainly in the Southern Hemisphere. Comparison of subunits found in the literature shows that they are suitable bioacustic markers for humpback in the usage of MAPA methodology. The data obtained in this study will be used to start the first sound database for marine mammals in the South Atlantic, called SONOTECA, in partnership with the SISMMAM (Marine Mammals Sound and Monitoring Integrated System)/IBAMA. / Neste estudo foi abordada a segmenta??o da can??o de baleias jubarte com base na defini??o das subunidades. As emiss?es sonoras das jubarte foram identificadas e caracterizadas de modo a estruturar o primeiro banco de dados de sons de mam?feros marinhos do Atl?ntico Sul Ocidental. Constatou-se a import?ncia dessas subunidades por apresentarem um grau de varia??o pequeno, ajudando na identifica??o da esp?cie em sistemas de Monitoramento Ac?stico Passivo Aut?nomo (MAPA). Os registros das vocaliza??es das baleias foram realizados pela equipe do Instituto Baleia Jubarte (IBJ) de 2006 a 2013, na regi?o de Abrolhos, Bahia, Brasil. Foram realizadas sete leituras das subunidades atrav?s do software Raven 1.4, avaliando-se: (1) Alta da frequ?ncia (Hz); (2) M?dia da pot?ncia (dB); (3) Energia (dB); (4) Frequ?ncia central (Hz); (5) Frequ?ncia m?xima (Hz); (6) Delta do tempo (s); e (7) Delta da frequ?ncia (Hz). Foram calculados a m?dia, o desvio padr?o, o valor m?nimo, e o valor m?ximo. Realizadas an?lises multivariadas das vari?ncias com o valores do teste Post Hoc onde p>0,05 n?o representa varia??o significativa ao ano. Nos anos de 2006, 2007, 2009 e 2011 houve qualidade satisfat?ria para realizar as an?lises, o que correspondeu a 14% do total das grava??es, com 4:06:54h de grava??es. Os registros analisados foram adquiridos nos meses de maior ocorr?ncia de jubarte. 862 subunidades foram identificadas e analisadas. As subunidades identificadas foram A, B e C. A subunidade A (n = 156; 18%), anteriormente encontrada em uma ?rea de alimenta??o no nordeste da Isl?ndia (2011), no Alasca (2012) e na regi?o de Abrolhos, em todos anos estudados. A subunidade B (n = 205; 24%), com ocorr?ncia em ?reas de alimenta??o da Isl?ndia (2000) e no Alasca (2012) e na ?rea de reprodu??o no Hava? (1991) e na regi?o de Abrolhos foram registradas em todos anos pesquisados. A subunidade C (n = 501; 51%) foi anteriormente registrada nas ?reas de reprodu??o de Madagascar (2009), Hava? (1989 e 1991), M?xico (2006), Austr?lia (2009) e Nova Caled?nia (2010) e na ?rea de alimenta??o da Ant?rtica (2010). Algumas subunidades n?o apresentaram diferen?as significativas em alguns anos estudados. As subunidades s?o preservadas ao longo dos anos principalmente nos par?metros alta frequ?ncia, frequ?ncia central, frequ?ncia m?xima, delta de tempo e delta da frequ?ncia. O par?metro delta do tempo demostrou tamb?m a sua m?dia e desvio padr?o mais uniforme, indicando que este deve ser usado como car?ter diferenciador nas an?lises de emiss?es sonoras de jubarte. A subunidade C apresentou uma grande distribui??o geogr?fica principalmente no Hemisf?rio Sul. A compara??o das subunidades encontradas com as registrads na literatura demostra que elas s?o adequados marcadores bioac?sticos para a jubarte no uso de metodologia do MAPA. Os dados obtidos no presente estudo ser?o usados para iniciar o primeiro banco de dados de sons para mam?feros aqu?ticos no Atl?ntico Sul, denominado SONOTECA, em parceria com o SISISMMAM (Sistema Integrado de Som e Monitoramento de Mam?feros Marinhos) /IBAMA.
