In the first decades of the Republic, the streets of the main Brazilian capital cities, especially of Rio de Janeiro and Recife, recently urbanized based on the Haussmanian Paris and smiled upon by the fever of cosmopolitanism that invested Europe, women had been used as runways where they could exhibit her imitated or imported models, especially in Paris. The iconography of the time and the advertisements conveyed by magazines and illustrated periodicals, such as the Almanach de Pernambuco and the magazine Kosmos, for instance, form the testimonies of the massive presence of the French in Rio and Recife, owners of stores and maisons, interested in fulfill the demands of the republican public. In spite of the Strong adherence of the Brazilians to the sociability models to the imported from Europe, the less-favored classes, through the popular literature, showed some resistance to these changes in the habits and clothing, especially in the Northeast, where traces of the Catholic and patriarchal moral and mentality were still alive.

The article seeks to reflect from a visual history of the elaboratión imaginary political and national identities and transnational comparative perspective between Brazil and Mexico in the first half of the twentieth century. The main focus is Mexican participation in the exhibition commemorating the centennial of Brazilian independence in 1922 and the dialogues in the film industry of both countries in the second half of the 1940s and beginning of 1950s.

Consider a finite body of mass m (C1) with moments of inertia A, B and C. This body orbits another one of mass much larger M (C2), which at first will be taken as a point, even if it is not completely spherical. The body C1, when orbit C2, performs a translational motion near a Keplerian. It will not be a Keplerian due to external disturbances. We will use two axes systems: fixed in the center of mass of C1 and other inertial. The C1 attitude, that is, the dynamic rotation of this body is know if we know how to situate mobile system according to inertial axes system. The strong influence exerted by C2 on C1, which is a flattened body, generates torques on C1, what affects its dynamics of rotation. We will obtain the mathematical formulation of this problem assuming C1 as a planet and C2 as the sun. Also applies to case of satellite and planet. In the case of Mercury-Sun system, the disturbing potential that governs rotation dynamics, for theoretical studies, necessarily have to be developed by powers of the eccentricity. As is known, such expansions are delicate because of the convergence issue. Thus, we intend to make a development until the third order (superior orders are not always achievable because of the volume of terms generated in cases of first-order resonances). By defining a modern set of canonical variables (Andoyer), we will assemble a disturbed Hamiltonian problem. The Andoyer's Variables allow to define averages, which enable us to discard short-term effects. Our results for the resonant angle variation of Mercury are in full agreement with those obtained by D'Hoedt & Lemaître (2004) and Rambaux & Bois (2004)

This study was carried out to assess the influence of bovine embryo culture medium Beltsville Agriculture Research Center (BARC), supplemented with FCS, BSA or PVA, on the in vitro oocyte maturation, evidenced by cleavage rate and blastocysts production at different developmental stages. Three experiments were performed, as follows: exp.1: addition of FCS to BARC medium at concentrations of 0, 5 and 10%; exp. 2: addition of BSA to BARC medium at concentrations of 0, 4 and 8 mg/ml; exp. 3: addition of PVA to BARC medium at concentrations of 0, 0.5 and 1.0 mg/ml. TCM 199 supplemented with bicarbonate, pyruvate, gentamicin sulfate, FSH, LH and FCS was used as control group. Oocytes obtained from cow ovaries at slaughterhouse were selected in PBS, and then matured in BARC medium supplemented with FSH, LH and gentamicin sulfate, according to the experimental design. Percoll gradient was used for sperm selection and TALP medium for IVF. In vitro embryo culture was in SOF-m medium; a humidified atmosphere with 5% CO2, in air, at 38.7oC was used for all steps. The number of oocytes reaching blastocyst, expanded blastocyst, and hatched blastocyt stages was recorded, respectively at 72 and 168 h post-insemination. ANOVA and Bonferroni t test were used to determine differences among groups. Differences of P<0.05 were taken as significant. Higher percentage (P<0.05) of cleaved oocytes was observed in group TCM + FCS than for the other groups matured in BARC supplemented with FCS or BSA, regardless the concentration used. However, the cleavage rate was similar between groups BARC plus PVA with 1 mg/ml (85.7%) and TCM + FCS (90.8%). Significant difference was found among groups for the production of blastocysts, with the control group yielding a higher number of blastocysts (results ranging from 47.4 to 51.4%, in comparison with groups using BARC + FCS (4.1 to 19.7%), BSA (1.4 to 5.6%) and PVA (5.7 to 10.6%). In conclusion, BARC medium supplemented with different macromolecules did not promote a beneficial effect on in vitro oocyte maturation, resulting in lower rate of cleavage and blastocyst production when compared with TCM + FCS medium.

The idea of "mature development" is based, frequently, on explanations of school failure: the student does not learn because he is immature and the school has to wait until he gets "mature". When one says that a child is not mature compared to the development already attained by an adult, one focuses only the quantitative differences between them and forgets that these new qualities of the adult did not arise by the maturation, but by the permanent appropriation process of the human culture. Thus, this idea of "maturity of development" expresses a deep biologization of the human being, reducing social and educational problems explanation to the biological apparatus of the individual. The purpose of this essay is to analyze the relationship between maturation and development, pointing out the limits of biologists’ explanations of human phenomena and the possibilities of explanation formulated by the historical-cultural theory to the organization of pedagogical work. This concept gives a new configuration to the role of maturation in the learning process and gives the school education a central role in the development of higher psychological functions. Thus, the school does not have to wait for the child’s maturation. Rather, it is its duty to create conditions for his/her maturation to become effective.

This thesis attempts to comprehend, through the work of Georg Simmel and Ulrich Beck, two distinct phases of modernity through the concept of individualism and individualization processes arising therefrom. A substantial formulation of the concept that remits to the conceptual transposition unscathed from one reality to another is not the main focus of this study. This is about, in advance, two distinct realities, conceptual and comparative examination that aims to weave the points pertaining to echoes - internalized and modified according to the complexity of the historical premises - the thought of Simmel in theoretical perspective of Beck. The forms can be characterized as individualism according to the socio-philosophical mores of Simmel in the intention to understand the forms assumed by individualism in modern history, as well as the derived individualization processes sustained by individual law. Therewith, is intended to transpose the optical analysis of contemporary Ulrich Beck and reap, through conceptual analysis, the points that refer to the influence and continuity of thought of Georg Simmel
