This study aims to analyze and demonstrate, based on a case study, the neglect in the systematization of its art spaces in the city of Castanhal – PA, due to the lack of investment in the different forms of contact with culture, whether formal or non- formal and/or informal. Under a magnifying glass is the reality, history and formation of this city in the interior of northeast Pará, Castanhal, or as it is known, the “Model City”, and a formal education apparatus, the public high school Dr. Inácio Koury Gabriel Neto, and its importance for the locality and the occurrence of art education in this educational space. Through observation, interview and project at the school mentioned above, it is noted that a strengthened relationship between formal education (in this case the school) with the artistic and cultural scene of the “model city” and a better dialogue with its students can be a way and way to expand and value the teaching/learning of art and the production of arts and culture within these locations that suffer from the abandonment of investments in the artistic segment.

The clinical and pathological alterations in horses, experimentally inoculated with Bothropoides jararaca, Bothrops jararacussu, Bothrops moojeni and Bothropoides neuwiedi poisons, were studied with the purpose to supply subsidies for the diagnosis of the poisoning. The liofilized poisons were diluted in 1ml of physiologic solution and subcutaneously administered to six horses, at doses of 0.5 and 1mg/kg (B. jararaca), 0.8 and 1.6mg/kg (B. jararacussu), 0.205mg/kg (B. moojeni) and 1mg/kg (B. neuwiedi). All horses, less those that received the poison of B. jararacussu, died The clinical signs began between 8min and 2h10min after the inoculation. The clinical course varied, in the four cases of lethal exit, from 24h41min to 70h41min, and was 16 days in the two horses that recovered,. The clinical picture, independent of the poison type and doses, was characterized by tumefaction at the site of inoculation, dragging on the ground with the hooves of the inoculated leg, inquietude, apathy, decrease of reaction to external stimuli, pale mucous membranes and hemorrhages. Laboratory exams revealed normocytic normochrômic anemia with progressive decrease in the number of erythrocytes, of hemoglobin and of the hematocrit, and leucocytosis due to neutrophilia. There was increase of alamina aminotransferase, creatinaquinase, lactic dehydrogenase, ureia and glucose, as well increase of the time of activation of protrombin and partial tromboplastina. At postmortem examination, the main findings were extensive hemorrhagic areas in the subcutaneous tissue, with the presence of non-coagulated blood, to a large degree associataed with edema (hemorragic edema), which extended from the inoculation site of the venom to the cervical, thoraxic and scapular region, and to the leg. In the periphery of the hemorragic areas existed gelatinous edema. There were great amounts of sanguinary liquid in the thoracic, pericardic and abdominal cavities. No significant histological alterations were found.

(2009) SOUZA FILHO, Antonio Pedro da Silva; BAYMA, Joaquim de Carvalho; GUILHON, Giselle Maria Skelding Pinheiro; ZOGHBI, Maria das Graças Bichara
Essential oils are known for their several biological activities. The biodiversity of the Amazon region is rich in essential-oil producing plants.The aim of this work was to study the potentially allelopathic activity of the essential oil of Ocimum americanum and to determine its effects on seed germination and growth of two weed species. Solutions of the essential oil were tested at concentrations varying from 100 to 2,000 mg L-1, considering their effects on seed germination (at 25 ºC and a photoperiod of 12 hours) and radicle and hypocotyl growth (at 25 ºC and a photoperiod of 24 hours) of the weeds Mimosa pudica and Senna obtusifolia. Factors related to concentration, specificity of the receiving plants and the parameters analyzed were decisive for the effects obtained. Overall, there was a positive relation between concentration and inhibitory effect. M. pudica tended to be more sensitive to the effects than S. obtusifolia. Seed germination was more affected by the essential oil, followed by radicle elongation and hypocotyl elongation. The observed effects can be attributed to the composition of the essential oil, that includes monoterpenes, sesquiterpenes, aliphatic compounds and phenylpropanoids. The compounds limonene, camphor and linalol, found in the essential oil, are known to have allelopathic activity.

Avaliação da aprendizagem em língua inglesa no primeiro ano do ensino fundamental em escolas públicas do município de Castanhal (PA)
(Universidade Federal do Pará, 2014-06-27) BARBOSA, Emília Gomes; CUNHA, Myriam Crestian Chaves da; http://lattes.cnpq.br/0057919162522146
This study investigates the assessment practices in the Teaching of English as a Foreign Language to Young Learners (LEC) in the first year of primary education in public schools in the city of Castanhal, PA. The research analyze which guidelines are contained in official municipal documents with regards to teaching and assessment in LEC, to describe the assessment practices developed by teachers in this context, to analyze the integration of these practices with LEC's teaching and learning goals, and to indicate pointers to make the assessment of learning practices more effective, theoretically and methodologically. To achieve the proposed objectives, a qualitative documentary study was conducted. We analyzed the official documents that guide teaching and assessment in LEC, 220 student development reports, which are recommended assessment tool for this school level, as well as interviews and questionnaires given to 14 teachers working in this context. The theoretical framework is based on the contributions of Cameron (2001), Strecht-Ribeiro (2005) and Scott and Ytreberg (1990) regarding the teaching and learning of LEC, as well as the discussion of some aspects of assessment of learning (HADJI, 1994, 2007; BONNIOL; VIAL, 2001; FERNANDES, 2009; PERRENOUD, 1999) and assessment of learning in LEC (MCKAY, 2006; IOANNOU-GEORGIOU 2011; SHAABAN, 2001). For data analysis, we used the Content Analysis technique (ROSA, 2013). The analysis results indicate a lack of coherence between the assessment practices and the teaching goals and principles in LEC. The data also reveal a lack of training for teaching, assessing and designing syllabus in LEC, combined with a known tendency to prioritize structural aspects in the teaching of foreign languages, instead of communicative activities. Finally, this study shows the need to promote other studies that investigate the assessment practices used in LEC, as well as the urgency to define official national guidelines for teaching and assessment that take into account the characteristics and needs of the children within this context.

Avaliação formativa na Licenciatura de Espanhol: autoavaliação e autorregulação em foco
(Universidade Federal do Pará, 2014-05-21) NEYRA, Patricia; CUNHA, Myriam Crestian Chaves da; http://lattes.cnpq.br/0057919162522146
This paper discusses an experience with formative assessment focused on self-assessment and self-regulation in language competences and learning strategies. The research reported here aimed to identify what students of Bachelor of Spanish Foreign Language (S/FL) self-assess and self-regulate in their learning, what is the impact of the self-assessment and self-regulation effective in their communicative language competence and ability to learn and, finally; what are the educational activities that promote self-assessment and self-regulation of these competences. To achieve the proposed objectives, we chose to conduct an action research, which was developed in the subject Spanish Language III of the Bachelor’s degree in Spanish at the Federal University of Para (UFPA) - Campus Castanhal. The theoretical framework is based on authors like Allal (1986; 2007), Bonniol and Vial (2001), Perrenoud (2007), among others. For data analysis, it was noted how three students in the class dealt with the proposed formative activities during the course and it also was related their performance in the subject with their attitude regarding those activities. The results show that initially, the language competences were the most assessed and self-regulated objects by the students. However, as the learners were induced to think about other dimensions of foreign language learning, some of them began to include the metacognitive aspects in their self-assessments and self-regulations, which favored an improvement of their communicative language competence and their ability to learn. The formative activities that provided the most effective self-assessment and self-regulation were the self-assessment guideline, learning dairy, the development of communicative goals and assessment criteria, as well as situations involving self-assessment, co-assessment and mutual assessment practices.

Comparação da sensibilidade de bovinos e búfalos à intoxicação por Palicourea marcgravii (Rubiaceae)
(2003-12) BARBOSA NETO, José Diomedes; OLIVEIRA, Carlos Magno Chaves; TOKARNIA, Carlos Maria Antônio Hubinger; RIET-CORREA, Franklin
In order to verify if buffaloes are more resistant than cattle to poisoning by Palicourea marcgravii, the plant was given per os simultaneously to buffaloes and cattle. Seven buffaloes and three head of cattle were used. Doses of 0.5, 1.0 and 2.0 g/kg did not cause signs of poisoning in buffaloes; but doses of 3.0, 4.0 and 6.0 g/kg caused death. In cattle 0.25 g/kg did not cause symptoms; but 0.5 and 2.0 g/kg were lethal. The influence of exercise on the onset of symptoms, the time which elapsed from the beginning of the administration of the plant to the appearance of symptoms, and the symptoms themselves, were similar in the two animal species. The clinical course was longer in buffaloes; whilst in cattle the period between the onset of severe symptoms and death lasted 9 to 17 minutes; in buffaloes it varied from 10 minutes to 1 hour 28 minutes. It can be concluded, that buffaloes are about six times more resistant than cattle to the toxic action of P. maracgravii. The lower incidence of deaths in buffaloes by poisonous plants in the Amazon region is, at least in part, due the lower sensibility of buffaloes to poisoning by this plant. Another factor responsible for the smaller number of buffaloes which die due to plant poisoning in the Amazon region, is possibly that buffaloes prefer the lowlands, e.g. temporarily flooded areas, which are the habitat of Arrabidaea bilabiata, the second most important poisonous plant of the Amazon region. This plant is less poisonous than P. marcgravii, and its habitat are the higher not flooded areas. So it would be safer, in order to diminish losses, to breed buffaloes instead of cattle in areas where P. marcgravii occurs. The reason for the greater resistance of buffaloes should be further investigated as a possible prophylactic measure to avoid poisoning by P. marcgravii in cattle. On the other hand, Australian investigators modified genetically the ruminal bacteria Butyrivibrio fibrisolvens by introducing a gene, isolated from a Moraxella sp, which codifies a dehalogenase, capable of hydrolyzing fluoroacetate, the poisonous principle of P. marcgravii. Transferring the genetically modified B. fibrisolvens into the rumen of animals, which consume plants that contain fluoroacetate, would be a viable method to control that poisoning through a ruminal detoxifying process for the toxin. Through preliminary contacts, the director of the consorcium in Australia, responsible for the modification of the bacteria, declared that he is interested to sell the technology to our country, but it would be necessary to know if it is permitted to introduce into Brazil the genetically modified bacteria. If allowed, it would be necessary to perform investigations on the viability and the methodology for using this bacteria to control P. marcgravii poisoning in our country.

Conditioned food aversion to control poisoning by Ipomoea carnea subsp. fistulosa in goats
(2014-07) OLIVEIRA JÚNIOR, Carlos Alberto de; CORREA, Gabriela Riet; TAVARES, Carla; SOUZA, Elda Ely Gomes de; CERQUEIRA, Valíria Duarte; PFISTER, James A.; COOK, Daniel; CORREA, Franklin Riet
Ipomoea carnea is a toxic plant often ingested by livestock in Brazil. Three experiments were conducted to determine if conditioned food aversion was effective in reducing goats' consumption of I. carnea. In the first experiment, 10 mildly intoxicated goats that had been eating I. carnea were averted using LiCl (175 to 200mg kg-1 body weight). These intoxicated goats did not develop an aversion to I. carnea, demonstrating that the technique is not effective in goats that are already accustomed to consuming the plant. In the second experiment, 14 naïve goats were placed in a pasture with I. carnea, and averted after they ingested the plant. In this group the aversion persisted until the end of the experiment, 2 years and 8 months after the initial aversion. In another experiment, 20 goats were placed in a pasture with I. carnea, and after consuming the plant were averted with LiCl. The averted goats were transferred to Marajo Island and periodically observed over a 2 year period at 2-3 month intervals to determine if they were still averted. The averted goats did not ingest the plant while grazing in the pasture, whereas in 6 neighboring goat farms the prevalence of intoxication from I. carnea poisoning was estimated to be about 40%. These results demonstrated the efficacy of conditioned food aversion to avoid ingestion of I. carnea in formerly naïve goats that had only recently begun to ingest the plant.

Constituir-se professora de ciências para crianças de 4 a 6 anos de idade: processos formativos do ensino e aprendizagem
(Universidade Federal do Pará, 2010-03-26) PEREIRA, Elisa de Nazaré Gomes; GONÇALVES, Terezinha Valim Oliver; http://lattes.cnpq.br/0496932429575513
In this research we assume the narrative as an epistemological support, because we understand that the narrative research helps us understand the processes of teacher education, knowledge and learning by which the subjects are replaced and thus constitute the process of identities. Our objective is to build relationships between the teacher education experiences lived and reported by the teachers investigated and their attitudes to teaching on the scientific literacy for children from 4 to 6 years of age. They were six subjects who participated in the research: two teachers acting in classes of 4 years; other two, with groups of 5 years, and two with classes for 6 years, which operate in 2 schools in the town of Castanhal (northeast of the State of Pará). In order to make the triangulation of the research, the corpus was composed from the following information collected: (i) transcription of semi-structured interviews with the six teachers; (ii) my field note observations of the pedagogical practices in science education which they have developed, and (iii) photographic records, which were analyzed from the perspective of textual analysis discourse. From a very careful analysis of the corpus, by means of readings and re-readings, of its deconstruction and unity, we built three axs of analysis: (i) the teachers’ education to teach Science: background knowledge; (ii) Conditions of Production of Teachers' Work: pedagogical implications; and (iii) Strategies for Teaching and Learning in Science Education. The analyzes of the results about the teachers’ experiences who were investigated during the process of early and lifelong education show that the professional preparation influences their conceptions and conducts educational when they teach science to children. As professional preparation we may consider the following aspects: the first contact to sciences in the context of Early Childhood Education and in the first year of elementary school throughout the course of teaching and/or graduate carried out and, the absence of a municipal plan or school of continuing education. In general, the teachers’ narratives also demonstrated that the implications of everyday teaching are related to some aspects as following: the little time they have for planning their pedagogical practices in science education, their lack of understanding of scientific concepts to be taught to children, the difficulties of access to sources of research and the large number of children per class. Still on the results of that study, from the reports of the teachers surveyed, and about what we have noticed in their pedagogical practices in science education, in general, the teaching strategies used by them are: circles of conversation; cutting and pasting; activities mimeografadas for textbooks; and use of concrete materials. When narrating their practices in science education, teachers demonstrated that, regardless of how each one teaches science to children, they believe they are contributing to their learning as children are been involved in the activities. Other possible contribution is based on the understanding that the teaching about science, which is propagated by the schools, is directly related to its reality.

This thesis has as its object of study the Municipal Board of Education, in order to understand the role played by this body, the decentralized educational policy Castanhal - PA. The problem of limited research on the organization and management of the educational policy of the municipality, as well as the political institutions of the Board in reference to the exercise of social control; the form of participation of civil society, especially the subaltern classes in the definition, implementation and evaluation of educational policies; and educational policies pursued since 2000 when starting the process of delegation of powers conferred upon the municipality locus of research, by the year 2011, comprising six (06) terms of two (02) years, which makes a total of twelve (12) years of management decentralization of educational policies, the institutionalization of Municipal Education System. For both, it was established as guiding hypothesis: the Municipal Board of Education Castanhal - PA, even with the delegation of powers, continued playing a role that approximates a control-management in the management of educational policies, rather than constitutive dimensions of social control, such as: monitoring, assessments and proposals. Were elected as axes of analysis for understanding the phenomenon investigated dimensions: technical inspection; political-ethical-evaluative and purposeful. This is a qualitative research, which focuses on a case study, whose data were revealed by means of bibliographic and documentary research, interviews with the social subject. The survey results confirmed the hypothesis that the working class could not exercise social control, in the analyzed period, from the dimensions aired this work, because of the bureaucratic state management model, which went on to influence the actions and procedures of the Board sometimes alluded. Indeed, the scale technical inspection ended at the micro level, the management of educational policy, without the effective participation of the working class; political and purposeful, dimension in turn was more related to the need to reduce bureaucracy of accreditation processes and approval of educational institutions; and the ethical-evaluative dimension was not possible because of some problems that were identified, including the methodology used for evaluation of educational policies, thus leaving the favor the more direct involvement of key users of educational services.

This research is inserted in the field of the History of the curriculum and has as its main objective to research what has changed and what is maintained in the curriculum identified as a result of the different official prescriptions which had been implemented in the institution currently called Escola Agrotecnica Federal de Castanhal (EAFC-PA), since its foundation on December 1st, 1921, as Patronato Agricola Manoel Barata, until the recent reforms implanted by the LDB nº 9394/1996. To carry out the collection of data on the History of the curriculum of this institution it was necessary a bibliographical revision and documentary research in the files of the institute, in the Public File of the State of Para and in the Department of Rare Workmanships of the CENTUR. This collection of data was carried out to select documents and iconographic sources on the institute related to the period researched. The bibliographical research subsidized the characterization and the events that had occurred in the Brazilian and Paraense society of the researched period (1921-1996). After this datacollecting, the analysis we developed followed three axles of inquiry, first we searched to find out the socio-political-economic conditions in Brazil and in the State of Para during the Republic until the decade of 1990, after that we identified the politics that had been established for agricultural education, so that we could finally delimit which influences of this ampler reality in the official curriculum were adopted by the EAFC-PA. From the analyses made in the curriculums prescribed adopted in the institute we conclude that throughout its existence, the EAFC-PA as an official institute of professional education in the Agriculture and Cattle area comes it has been adopting these curricular models to get adapted to the demands established by the social and economic projects of the Government at each time.

The study presents the debate concerning the transports in the space of circulation between Belém city and Castanhal city. The objective of this study is to demonstrate and to prove the inadequacy of the public transportations and the need of public politics than consider new variables in the metropolitan space, as the passengers' alternative transport, towards the regional development. The methodology used is historical and dialectical materialism and the research is qualitative and quantitative character, where did desk research and field research. This work is divided in 3 chapters: "Inferior circuit of the economy, state and transport system"; it "Transports alternative of passengers between Belém and Castanhal: a precarious complementarity"; it "Transports alternative of passengers: a new space variable in the metropolis". Where we drew the discussions concerning to demands for the transport and the need of state intervention in the circulation system, to give the necessary connection to the metropolitan space. To develop the study it was made a ten year-old temporary cutting (1998 - 2008), and space starting from the people's circulation between Belém and Castanhal.

This work emerged from the decision to work with literary literacy within a class of 25 students in the 9th grade of primary education in a state school of primary and secondary education in Castanhal, a city located approximately 73 km from Belém. The work has developed for over a month (seven classes of two hours each), and has sought to reveal the initial contact with the literary text, by reading four texts from the book Pequenas descobertas do mundo, from the writer Clarice Lispector: Tortura e glória, Restos do carnaval, O primeiro beijo e Banhos de mar. The activities were grounded in accordance with the basic didactic sequence proposed by COSSON (2006) and the reading strategies proposed by GIROTTO & SOUZA (2011), that emphasize the communicative characteristics of the literary text and the explanation of the skills used by teachers, more experienced readers, to their students, thus enabling the understanding of the mechanisms that are put into action, at the time of reading a literary text. The reading of the full texts in the classroom, with pauses for clarification of used reading strategies, along with comments on each text, was accompanied by the reading of other texts from other authors, as well as listening to music, and presenting of videos and images. We believe that this work happened in a positive and satisfactory way, because provided the contact between students with one of the most important Brazilian writers, promoted useful moments of dialogue between the class and the teacher about the texts, paving the way for students to continue on the search for moments where literary texts provide enjoyment and learning.

Formas espaciais recentes da urbanização na Amazônia: a dinâmica socioespacial do município de Castanhal em face do processo de dispersão metropolitana de Belém
(Universidade Federal do Pará, 2012) ALVES, Cyntia Santos Daltro; TRINDADE JÚNIOR, Saint-Clair Cordeiro da; http://lattes.cnpq.br/1762041788112837
The metropolitan dynamics that characterize the current amazon context, lead to an urban spatial reshape that need to be considered, based on a dialectical reading of this reality. In Belém, it is noted that the metropolis shows a dispersed mold. As it decentralizes, it expands, creating new expansion arrays beyond the considered legal metropolis’ borders. In this sense, this paper’s objective is to analyse the city of Castanhal’s socio-spatial dynamics against the sprawl process in Belém, considering the notorious link between them. In order to achieve this goal, three variables were considered: the providing of residential areas, industrial production and access to basic services. Therefore, the interpretation method based on the historical and dialectical materialism was used as theoretical-methodological tool, where the relations of production are analyzed as a social-historical consequence. That said, the metropolization process and urban sprawl must be realized from the dialectical movement of society’s spatial using. About the technical and empirical instruments, it must be said that this research’s nature is approached in a qualitative and quantitative perspective. In the quantitative perspective, some techniques were applied: the urban expansion quantification of Castanhal made from an analysis of satellites images from 1984, 1994 e 2008, using a software called ARCGIS 9.3, as well as the making of graphics and tabs using gathered data from official bodies, such as the Brazilian Institute of Geography and Statistics (IBGE), in order to statistically identify the relations force between Castanhal and Metropolitan Region of Belém (RMB). For the qualitative perspective, techniques such as survey and bibliographic analysis were used, as well as documental analysis and survey, and the making of interviews with representatives of the main Castanhal’s industries and distributors, in order to examine this city’s industrial production and its link to the metropolitan sprawl in Belém. Based on gathered and analyzed data, it was found that the urban spatial use in Castanhal dedicated to residences, industries and the third sector, create an interdependency link with RMB. One could infer that such relation is created by a new metropolitan configuration, based on flux dynamics that leads to the existence of an more amplified, disperse and discontinuous urban unity, confirming the need to study such metropolitan phenomenon beyond its institutionalized borders, and the importance of understanding the urbanization process that leads to metropolitan considered features on certain areas.

Spirochaetes transmitted by ticks are microorganisms of worldwide distribution, which infect wild, domestic animals and human beings. A total of 300 equine sera from four municipalities: Ananideua (58), Belém (61), Castanhal (131), and Santa Izabel do Pará (50), were evaluated for Borrelia burgdorferi by an Elisa test. There were no significant differences (P<0.05) among municipalities, breed, sex or husbandry. A total of 80 (26.7%) horses were B. burgdorferi positive with titles of 1:800, 72 (90%) horses, 1:1.600, 6 (7.5%) horses, and 1:3.200, 2 (2.5%) horses. The results were similar to those in the USA, where related frequencies ranged from 7 to 75% in asymptomatic seropositive horses. The presence of anti-B.burgdorferi homologous antibodies in horses from four municipalities in the metropolitan mesorregion of Belém suggests the possibility of occurrence of human cases in the region.

Babesiosis, anaplasmosis, and trypanosomosis are relevant diseases, potentially causing morbidity in cattle, leading to economic losses. Borreliosis is import as a potential zoonosis. The objective of this study was to determine, by indirect enzyme-linked immunosorbent assay (ELISA), the frequency of seropositive cattle to Babesia bigemina, B. bovis, Anaplasma marginale, Trypanosoma vivax and Borrelia burgdorferi in cattle from the Northeastern region of Pará, Brazil. Sera samples from 246 female adult cattle from municipalities of Castanhal and São Miguel do Guamá were used. Crude antigens ELISAs were used to detect antibodies to all agents, except to A. marginale, to which an indirect ELISA with recombinant major surface 1a protein (MSP1a) antigen was used. Overall frequencies of seropositive animals were: B. bigemina - 99.2%; B. bovis - 98.8%; A. marginale - 68.3%; T. vivax - 93.1% and B. burgdorferi - 54.9%. The frequencies of seropositive cattle to B. bovis and B. bigemina suggest a high rate of transmission of these organisms by tick in the studied region, which can be classified as enzootically stable to these hemoprotozoans. The low frequency of seropositive cattle to A. marginale may be attributed to a lower sensitivity of the recombinant antigen ELISA utilized or a distinct rate of inoculation of this rickettsia by ticks, as compared with Babesia sp. transmission. The high frequency of seropositive cattle to T. vivax indicates that this hemoprotozoan is prevalent in herds from the Northeastern region of Pará. The rate of animal that showed homologues antibodies to B. burgdorferi indicates the presence of the tickborne spirochaetal agent in the cattle population in the studied region.

The present study describes the understanding that the university teacher attaches to his/her professional identity and to the identity that the Physical Education course aims to beuild in its students, and was developed with 10 teachers at the College of Physical Education, Castanhal Campus of Pará Federal University. The central thesis is that the area of Physical Education, as it does not have an object of study of its own that sustains a professional identity, is in an epistemological crisis, slithering in pedagogical practices of teachers that tend to reproduce contents learned in their initial academic courses and from dialogues established with theoretical-methodological conceptions that do not match with the Pedagogical Project of the Course. It is a qualitative research, with phenomenological approach, meant to answer the following questions: What professional identity(s) do College Teachers assume in the Castanhal/Pará Physical Education Course? What professional identity(s) does the Castanhal/Pará Physical Education Course forge in students? Empirical data were produced by means of a questionnaire and a structured interview, based on the “Técnica de Elaboração e Análise de Unidades de Significado” (Development Technic and Units of Meaning Analysis) (MOREIRA; SIMÕES; PORTO, 2005), which resulted in the units of meaning. The empirical data is supported by the discussion on the professional identity by Dubar (1997, 1998, 2005, 2009), Sergio (1995, 1999, 2003, 2008) and Bento (2004, 2006, 2012). The study revealed the difficulties of teachers who work in the Physical Education College establishing the professional identity of the area, due to the absence of such discussions, ever since their graduation courses and in their professional lives. We point out to the need to broaden the debate on these issues that evidence the gap between the Pedagogical Project of the Course and the teachers‟ practice in classroom. We conclude that the collerge‟f teachers do not establish this consensus between what the PPC proposes and what the curriculum explains, not defining the identity of the future teachers that they intend to place in the job market.

Infecção transplacentária e intrauterina por Brucella abortus em búfalos (Bubalus bubalis)
(2015-11) SOUSA, Melina Garcia Saraiva de; SALVARANI, Felipe Masiero; BOMJARDIM, Henrique dos Anjos; FONSECA JÚNIOR, Antônio Augusto; PREIS, Ingred Sales; BRITO, Marilene de Farias; LEITE, Rômulo Cerqueira; BARBOSA NETO, José Diomedes
The objective of this study was to detect Brucella abortus and injuries caused by the bacteria in fetal membranes and fetuses. Twenty buffaloes serologically positive for brucellosis were used and subjected to stamping for collection of material from the closed uterus of several months gestation. Fetal age was determined by ultrasound examination and the size of fetuses was measured at necropsy. The samples were subjected to histopathology and qPCR. From the second month of pregnancy on it was possible to detect the presence of B. abortus DNA in amniotic fluid, allantoic liquid and uterus, and from the fifth month on in placenta, heart, spleen, kidney, lung, intestine, liver and lymph nodes of the fetuses. The main pathological findings were fibrinous suppurative necrotic placentitis, and chronic endometritis.

Influência da variação sazonal de atributos de fertilidade do solo sobre a biomassa microbiana em uma cronosseqüencia de plantio de palma de óleo (Elaeis oleifera (Kunth) Cortés) no Nordeste Paraense
(Universidade Federal do Pará, 2013-02-19) SILVA JUNIOR, Alberto Cruz da; RUIVO, Maria de Lourdes Pinheiro; http://lattes.cnpq.br/9419564604488031
Brazil has about 32 million hectares of areas with capability to oil palm’s expansion and more than 90% of these are in the Amazon. There is need to understand the interaction of new plantations and its development with the environment. This study was conducted in Dende do Pará SA (DENPASA), commercial plantations company, and aimed to evaluate precipitation’s seasonal variation on the soil fertility and thus on soil biomass in a chronosequence of oil palm plantations with 5, 8 and 12 years and secondary forestry. We measured / estimated and correlated the attributes carbon microbial biomass (CSMB), total carbon (CTOTAL), total nitrogen (NTOTAL), soil basal respiration (SBR), metabolic quotient (qCO2), carbon microbial biomass / total carbon ratio (CBMS: CTOTAL), carbon / nitrogen ratio (C / N), gravimetric moisture (Ug), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), aluminum (Al), effective exchange capacity of cations (CTC) and aluminum saturation (m). The CBMS was the attribute most sensitive to differentiate areas of study and dry and rainy seasons. Chemical characteristics of soil fertility and soil microbial biomass were correlated stronger and in greater numbers during the rainy season. Chemical attributes of soil fertility and soil microbial biomass presented correlation more strong and in greater numbers during the rainy season. The microbial indices qCO2 and CBMS:CTOTAL proved that conventional planting areas can be relatively efficient in relation to C dynamics compared to secondary forest area.
