Histologia comparada de brânquias, fígado e sangue em peixes da espécie Prochilodus lineatus, expostos a águas contaminadas

Os estudos hematológicos das diferentes espécies de peixes são de interesse ecológico e fisiológico, auxiliando na compreensão da relação entre as características sanguíneas, a filogenia, a atividade física, o hábitat e a adaptabilidade dos peixes ao ambiente. No experimento realizado foram testados os efeitos de águas contaminadas em parâmetros hematológicos de peixes da espécie Prochilodus lineatus, em períodos de coleta de 7 e 20 dias, nos quais o sangue foi coletado com seringas heparinizadas, foram montadas lâminas de esfregaço , as quais foram coradas pelo corante de Leishman. Estas lâminas foram analisadas e fotografadas com o auxílio de um microscópio óptico Leica, no qual foram feitas contagens totais de células brancas e contagens diferenciais de trombócitos e leucócitos, para a análise estatística. O grupo exposto ao Lago Azul apresentou uma elevação no número de leucócitos e no total de células brancas, evidenciando que os contaminantes químicos do ambiente estavam atuando de forma semelhante a um antígeno no corpo do animal fazendo com que suas células de defesa se proliferassem. Quanto ao grupo exposto ao detergente, observou-se que após os vinte dias de experimento ocorreu uma diminuição no número de trombócitos. Tais resultados evidenciam que a variação no número de leucócitos apresentou-se como um indicador de poluição ambiental e que os detergentes biodegradáveis podem em certo tempo de exposição ocasionar um déficit em funções vitais de peixes como à coagulação e a prevenção contra infecções, eventos ligados diretamente com os trombócitos. A maioria dos vertebrados aquáticos possui brânquias, estruturas especializadas nas trocas gasosas e responsáveis por grande parte das trocas iônicas. Este órgão acaba por absorver grande parte das substâncias presentes na água, que ao caírem na...(Resumo completo, clicar acesso eletrônico abaixo)

Estados emocionais em professores recém-formados: análise contextual

In general, the early career is a period marked by crises. Hubermam (1992) points out that this period is considered by the teacher as one of life's most difficult professional teaching. According to Machado (2004), the physical education worked only in competitive perspective in school, does not contribute to the school to perform its social role. This approach encourages the use of stigmas, labels and prejudices, so common in school, that marginalize even more students from lower classes, and can make the sport of high performance within the school walls create students with low self-esteem and low motivation within other possible disorders . Thus, this study presents the fundamental importance to aid and support to novice teachers, so that they can understand, and address key emotional aspects that interfere in their practice. Thus, our aim was to identify the most recurrent emotional processes in novice teachers identify and also how these emotional states can influence the professional and personal attitudes of these teachers. Through a bibliographic we seek statements, reports and case studies that provide enough material to our analysis and interpretation in order to collaborate with the study area and proceed to proposals that are not unreasonable or tied to the current system. Among the emotional states reported in the literature, we highlight the main, more present and influent in the beginner teacher as listed as follow: Anxiety, Stress, Fear, Shame, Low Self Confidence and Motivation. Considering these states, Damasio (1996) reports that the United Emotional directly influenced the style and efficiency of cognitive processes, in other words, interfere with the performance of teachers in the teaching front. Thus, Machado (2006) points out that the teacher should have a set of techniques and procedures that drive their practice in a manner appropriate to the leading group. Therefore, the knowledge of Psychology of Physical...

O fantástico em Coraline: uma análise semiótica

The English writer Neil Gaiman has a varied background in various genres of literature and comics. His novel Coraline (2002) was considered a bestseller and received numerous adaptations, including versions for the comics (U.S., 2008, illustrated by P. Craig Russelle) and for a musical off Broadway (USA, 2009). The object of analysis chosen for this research was the adaptation of Coraline for film, Coraline (U.S., 2009), stop motion animation directed by Henry Selick. In the eyes of the general public the film stands out for being an engaging animation. Under a closer look, Coraline becomes a valuable object of study that incorporated the technique of stop motion at the same time that modernized the fantastic genre, usually directed to children and youth, but in that case, reaches many audiences. The objective of this research is to analyze the animation based on theory of origin greimasian, focusing on the narrative that constitutes the fantastic genre in order to infer the regularities of genrer and the specificities of audiovisual product

As relações públicas e a gestão da comunicação integrada nas organizações resilientes do século xxi: uma análise dos meios de comunicação da ONG Periferia Legal

The implications of modernity and globalization stimulated the establishment of a new type of organization. Resilient organizations, as they will be called, representing the twenty-first century and are aligned with the social, political and economic context for their adaptability and flexibility. The study of the case will be the communication of the NGO Periferia Legal, also linked to the plane of the creative economy because of the intangible asset it produces. The study will be focused on the ways which public relations can help in the development of the NGO by analyzing their media. Thus, the three fronts of communication from the NGO (external, internal and institutional) will be analyzed through observations and interviews and their channels are categorized into: inefficient, low efficiency , average efficiency and efficient. The media will be key to understanding the phenomenon and the degree of efficiency will be marked as it achieves the proposed and designed objectives by the project itself - through the mission and vision of the NGO - using communication. In this way, the study seeks to understand the characteristics of resilient organizations from the standpoint of public relations

Tornar-se professor: desvelando a atuação docente no início do exercício da docência

This research, based on authors such as Was (1999), Guarnieri (1996 and 2005), Freitas (2002 and 2007) argue that the understanding of teacher education as a complex continuum aimed at understanding the initiation of the educational performance in the first five years of professional practice, by analyzing the history of teaching teachers early in their career. As we contemplate the specific objectives of interest to examine the training received to enter and work in the classroom and the experiences in teaching at undergraduate students. To perform the empirical study we adopted the use of semi-structured, guided by an outline of issues significant to the conduct of the respondents' narratives. The main results can highlight the difficulties encountered at the beginning of the educational performance are recurrent, data analysis shows that there is a significant increase in the duties of the teacher. With the study arrives at the premise that we must rethink the quality and structure of training courses aimed at improving the quality of performance of professional education, but for this to occur there must be deepening of studies and improvements not only in initial training and in continuing education courses. It is understood here that the training is not solely responsible for the current educational scene, which encompasses the question of the beginner there are many issues to be studied, such as public policies, structuring the curriculum, pay, but the training is beginning to there are faculty prepared to act

A poesia de Harryette Mullen e a (des)construção da mulher e de suas fronteiras

Harryette Mullen is a contemporary African-American poet whose work has been increasingly analyzed and commented upon in American literary circles. Along her poetic career, one can identify the development of a complex relationship with the construction of the (black) female identity. Early in her career such construction involved the affirmation of a safer, if not “truthful” locus that could encompass the meaning of the female existence, which has ultimately come to develop a deconstruction, in her current poetry, of any centrality or essentiality in the search for a an authentic female identity. Translations of her poems will be presented in order to investigate their implication for understanding the fragmented body of the contemporary woman.

O passado no presente: João Gilberto Noll, leitor de Álvares de Azevedo

In the mid-nineteenth century, in his fruitful years of the perhaps best-known shortest literary career, Álvares de Azevedo wrote this verse “As ondas são anjos que dormem no mar” (“The waves are angels who sleep in the sea”). In the presentation of João Gilberto Noll’s young adult novel Anjo das ondas (Angel of the waves) in 2010, Ivan Marques states that the character in the novel, Gustavo, “with his adolescent passion, and torn spirit with overflowing lyrics, could even be compared to our tropical Byron”. João Gilberto Noll establishes a connection between him and Álvares de Azevedo that invites the reader to go beyond a first reading level of his work, seeking evidence of dialogue ratification between two apparently distant writers. The subtle intertextuality exceeds the initial clue and can be detected on Noll’s theme development from the history of Gustavo, a troubled teenager in search of his identity. Noll’s affinity to Álvares de Azevedo can still be captured in his narrative texture, in voices coming from his text; however, they also reveal to be unique and original features of his literary production. An apparent exercise in style shows that each author fulfills his mission by expressing, in his own way, the feeling of his time. In addition, it shows that through aesthetic emotion, literature allows us to transcend time and space.

Algumas considerações sobre homotopia e homologia

The cohomological invariant E'(G,W) and some properties

Let G be a group, W a nonempty G-set and M a Z2G-module. Consider the restriction map resG W : H1(G,M) → Pi wi∈E H1(Gwi,M), [f] → (resGG wi [f])i∈I , where E = {wi, i ∈ I} is a set of orbit representatives in W and Gwi = {g ∈ G | gwi = wi} is the G-stabilizer subgroup (or isotropy subgroup) of wi, for each wi ∈ E. In this work we analyze some results presented in Andrade et al [5] about splittings and duality of groups, using the point of view of Dicks and Dunwoody [10] and the invariant E'(G,W) := 1+dimkerresG W, defined when Gwi is a subgroup of infinite index in G for all wi in E, andM = Z2 (where dim = dimZ2). We observe that the theory of splittings of groups (amalgamated free product and HNN-groups) is inserted in the combinatory theory of groups which has many applications in graph theory (see, for example, Serre [12] and Dicks and Dunwoody [10]).

A note about splittings of groups and commensurability under a cohomological point of view

Let G be a group, let S be a subgroup with infinite index in G and let FSG be a certain Z2G-module. In this paper, using the cohomological invariant E(G, S, FSG) or simply E˜(G, S) (defined in [2]), we analyze some results about splittings of group G over a commensurable with S subgroup which are related with the algebraic obstruction “singG(S)" defined by Kropholler and Roller ([8]. We conclude that E˜(G, S) can substitute the obstruction “singG(S)" in more general way. We also analyze splittings of groups in the case, when G and S satisfy certain duality conditions.

Some considerations about cohomology of finite groups

In this work we present some considerations about cohomology of finite groups. In the first part we use the restriction map in cohomology to obtain some results about subgroups of finite index in a group. In the second part, we use Tate cohomology to present an application of the theory of groups with periodic cohomology in topology.
