The development of populations of gastrointestinal parasites resistant to antihelmintics has led to seeks new alternatives its control. Stimulation of natural immunity by means of animal nutrition has shown promising results in controlling nematodes in sheep. The addition of protected fat sources, containing essential fatty acids, may be an alternative due to many effects, among them, regulation of immunity expression and regulation of the inflammatory response by immune effectors. The aim of this study was to estimate correlations between haematological and parasitological patterns, animal performance through weight and body condition, under the influence of protected fat in ewes. Fifty Santa Ines sheep, in the final third of pregnancy or postpartum, in paddocks of Panicum maximum, received, individually, 200 g per day of concentrate, isonitrogenous and isocaloric diets, with or without the addition of protected fat. In general, except for total leukocytes and eosinophils, almost all of Pearson correlation coefficients of other variables were significant. However, the protected fat, in the amount offered, had no antihelmintic effect.

We interviewed 21 farmers in order to access which sanitary practices adopted in the production systems of beef cattle on farms located in São Paulo, Mato Grosso, Mato Grosso do Sul and Rondonia. The survey was conducted through a qualitative approach to the collection of data obtained through questionnaire and personal interview with the landowners. We questioned the attitudes and sanitation procedures in these current production systems such as veterinary assistance, preventive health practices and disease surveillance, knowledge of health hazards for the safe production of food, animal feed, vaccine and immunizations, registration system, measures with newborns, products used in the environment and animals, grace period, employee training, destination of the dead animals, among others. Along with the data found that only 30% of properties had veterinary care, 67% said they meet the expiration dates of the products, although it was not mentioned on the products if there were any. In only 48% of properties were veterinarians who prescribed drugs to animals. Only two of the owners confirmed buying and using expired products in animals and only 48% have received some training on the property. In this setting, it is evident that farmers should be better prepared for insertion of its products in a highly demanding and competitive market. In this context, add value to the product depends mainly on the condition of sanitation of the herds.

Aiming to assess the efficacy of the treatment, to verify the occurrence of possible disease relapses and to search for the presence of parasites after the treatment, seven dogs naturally infected by Leishmania sp., were submitted to a treatment with meglumine antimoniate and allopurinol. For this, lymph node and bone marrow aspiration biopsies were carried out at seven moments. After the end of the six-month observation period all dogs were submitted to euthanasia. Then, spleen and liver “imprints” and in vitro cultures were carried out to search for amastigote forms of the parasite. All animals presented remission of the symptoms and during all the observation period no dog presented relapse of the disease, although amastigote forms of the parasite were observed in two of the animals at the end of the experiment. Thus, it was possible to conclude that the treatment promotes clinical healing but it does not eliminate the parasites completely.

Based on systemic-cybernetic-new paradigm vision and social constructionism, the paper is an invitation to reflect on the importance of language in the maintenance and the possibility of changing unequal relational patterns, mainly related to issues of gender. Studies on language and verbal behavior of women and men, besides their representation in the media, are examples to illustrate the need advocated here, to changing patterns of inequality guided by gender differences that influence and are influenced by the culture, conveyed in our social network. This paper is a contribution for the clinical work with families and couples, from the perspective of the current behaviors, based on refrains spread by the media which became popular, since it is based on clinical and nonclinical observations about human relationships and its representation in the media and artistic productions.

Taking referential theoretical conceptions of mathematical knowledge present in some of the main mathematics philosophical currents and considering that the teacher´s practice is influenced by his conception of mathematical knowledge, this research aims to understand the conceptions of mathematical knowledge and its teaching and learning teaching of future mathematicians. It follows a qualitative approach (case study) in which the data were collected by semi-structured interviews and document analysis. This investigation has pointed out that Mathematics together with Mathematics Teaching (or part of this: on the didactic and pedagogical knowledge of how to teach) could be important to formation of the future mathematician, who will probably teach in a college or university.

Located in northeastern Brazil, the evolution of Araripe Basin has been associated with the fragmentation of Gondwana and opening of the South Atlantic. The Santana Formation belongs to the post-rift sequence of the basin and is characterized by the presence of laminated limestones in the lower portion (Mb. Crato), evaporite (Ipubi) and siliciclastics (Mb. Romualdo). For better understanding of the Romualdo's stratigraphy, depositional environments and tract of systems, a stratigraphic analysis was made with representative columnar sections of the unit. Sedimentary facies have been described in detail, as well as paleocurrents measured at different stratigraphic levels. It was found that the contact of Mb. Romualdo with the carbonate-evaporite section (Mbs. Crato and Ipubi) is a unconformity, evidenced by residual lags and thin layers of conglomerates above the contact. Above the conglomeratic levels predominate fine sandstones / medium interlayered with calciferous green shales. The percentage of shales increases towards the top, featuring retrogradational stacking culminating in layers of coquinas, excellent stratigraphic mark in the basin. Thin layers of coquins of gastropods comprising equinoids, located on the shale section, present in three sections marine deposits are associated with surfaces ravine. The upper section is characterized by recurrent facies of green shales, sandstones intercalated with sandstones progressively become more frequent towards the top of the unit, featuring the regressive part of the cycle. The sandstones present cross-stratification, often with mud clasts and clay layers in the foresets, and beddings of flaser type and wavy in heterolitic facies, suggesting the action of tidal currents. Paleocurrents measured in the sandstones show gaps with opposite flow directions outlining bipolar standards, which reinforce the interpretation of shallow marine environment influenced by tides during the sedimentation...

A competição nos mercados, o fácil acesso a informação tornou a estratégia, nas últimas décadas, um campo de estudos e de essencial importância para o crescimento e desenvolvimento das companhias, um aliado para a empresa se diferenciar no mercado, conseguindo destaque e atingir seus objetivos, minimizando riscos. Esse artigo tem como objetivo, demonstrar duas correntes de formulação estratégica, sendo uma teoria do Posicionamento, tendo como principal mentor Michael Porter, e a segunda a teoria do Planejamento, sendo Chiavenato como principal autor. Após isso, será caracterizado o setor do Agronegócio brasileiro, que possui um papel fundamental no cenário econômico nacional, que irá subsidiar a análise estratégica e estudo de caso da empresa JBS S.A. O objetivo final é entender o processo estratégico da empresa e caracteriza-lo de acordo com as teorias apresentadas
