A educação da mulher em Lima Barreto

Lima Barreto has built an educational conception of women in his fictional productions despite nuances inciting scholars to debate his writings and label him as misogynist and philogynist. Thus, the objective of this study is to comprehend, through signs present in his literary works, how women used to be educated in early twentieth century to accomplish the historical differences in gender relations. The main reason for this extract is the periodicity of his publications that started in 1900 by means of chronicles in newspapers and ended in 1922 after his death. For this, we identified codes and rules forged in the social processes to be assimilated by children through diverse institutions, aiming to incite the production of behaviors and social practices represented by the existence men and women in an ever changing society. Gender relations are analyzed within a society for their configuration concept by Nobert Elias (1970) as interdependence bonds among individuals. An investigative method proposed by Ginzburg (1989) was the most adequate to conduct the research on the work of Lima Barreto because it enables us to reconstruct the education concept for women. The dramas and novels analyzed point out the construction of categories such as women education, family, love and seduction revealing the engagement of Lima Barreto with the social problems of the period investigated. It was concluded that gender differentiation has come from family education which kept men and women in opposing sides giving them a marriage perspective that, after consummated, would bring frustration to women causing them to adopt confronting practices against domination strategies through celibacy or adultery. This research constitutes a reflection based on determined representations like justice, respect and duties that were the ideas defended by Lima Barreto in his writings, concerning both broader situations in social life and particular gender relations

Astrócitos imunorreativos à proteína glial fibrilar ácida (GFAP) em sistema nervoso central de equinos normais e de equinos com leucoencefalomalácia

A proteína glial fibrilar ácida (GFAP), subunidade dos filamentos intermediários do citoesqueleto celular, está presente no citoplasma de astrócitos. Técnicas imunohistoquímicas com anticorpos primários anti-GFAP são geralmente empregadas para identificar astrócitos no sistema nervoso, permitindo verificar também sua hipertrofia. Vários estudos mostram a distribuição, a morfologia e a citoarquitetura de astrócitos em várias regiões do SNC do homem e de animais de laboratório. No entanto, em animais domésticos e, especialmente em equinos, poucas informações estão disponíveis. No presente trabalho, verificou-se a densidade e a morfologia de astrócitos imunorreativos à GFAP na substância branca da córtex cerebral de equinos com leucoencefalomalácia (LEM) comparando-se esses aspectos com o de equinos normais. Animais com LEM apresentaram hipertrofia de astrócitos em áreas próximas às lesões, representada pelo aumento do corpo celular, do núcleo e dos prolongamentos citoplasmáticos. O número de astrócitos apresentou-se reduzido e a imunorreatividade foi mais acentuada. Nos animais normais, verificou-se distribuição constante de astrócitos imunorreagentes com características de fibrosos. Alterações vasculares nos animais com LEM, como por exemplo degeneração de endotélio vascular, também foram observadas, podendo estar associadas às alterações astrocíticas.

Luiz Antônio dos Santos Lima e o seu legado educacional (Natal/RN, 1910-1961)

This research aims to analyze the intellectual practice of Luiz Antônio Ferreira Souto dos Santos Lima. This is done considering the author´s legacy related to the History of Education in Rio Grande do Norte/Brazil in the time span of 1910 to 1961. Thus, the research is grounded on assumptions that rely on the Cultural History field. The research also dealt with dialogues between the author and Chartier (1990), Elias (1994), Morais (2003; 2006), as well as Gondra (2003). For the bibliographical research the work dealt with a vast array of documents such as newspapers called A República and Diário do Natal, Pedagogium, Revista do ensino, as well as state laws and decrees These documents were obtained at the Historical and Geographical Institute in Rio Grande do Norte. The research also dealt with School Bylaws and a medical doctoral thesis called Mental Hygiene and Education that was written by Luiz Antônio dos Santos Lima. Other documents were obtained at the State´s Public Archive, such as the Book of Honor, Work Records, Reports and Minutes of the General Directorate of Public Instruction Meetings. It was possible to infer that professor Luiz Antônio dos Santos Lima was teacher at Grupo Escolar Augusto Severo, the Atheneu as well as some local grade schools. The professor had a broad role in society, in administrative positions such as the Presidency of the Association of Teachers of Rio Grande do Norte, as Grade School Director in the School of Pharmacy and the State Education Department. He was also a member of the Academy of Arts and a partner at Historical and Geographical Institute in Rio Grande do Norte. The professor has also concerned with issues related to teaching good habits such as feeding, grooming, discipline, game morals, temperance, smoking, sex education; all of which necessary for the formation of healthy children. He was an enthusiast of an intuitive method and teaching lessons through practice, that he considered key elements in education. It is seen that professor Luiz Antônio dos Santos Lima had presence in the State´s health education and that his ideals were line with the ideal of modernity of the early twentieth century

A concepção de ensino sob medida na obra hygiene mental e educação (1927), de Luiz Antônio dos Santos Lima

This dissertation examines the concept of the personalized teaching proposed by the physician and educator from Rio Grande do Norte Luiz Antonio dos Santos Lima, in his doctoral thesis "Mental Hygiene and Education," published in 1927. To do so, we start from the assumption that this thinker appropriated part of the educational theory formulated by Èdouard Claparède - specifically, in the case of the teaching concepts of the personalized teaching and comprehensive education designed by the Swiss intellectual - and, considering the Brazilian social reality of early twentieth century, reframed these concepts, adapting them to the country context. To implement the proposed idea, the bibliographical study was the option chosen, and so was done through a theoretical research which had as a reference authors whose studies referred to the Brazilian historical moment in the late nineteenth and early twentieth century, our examined time frame. As for the understanding and the methodological analysis of discourse, seen as socially constructed, the Foucault postulations were studied under an analytical approach, in which the disciplinary society is analyzed from the relations of power and knowledge that exist in it. The main source of this research was the work of "Mental Hygiene and Education," published as a requirement to the obtainment of Luiz Antonio s medical degree by the Rio de Janeiro Medicine School. Thus, it was found that the conception of personalized learning to the comprehensive education of students, as proposed in the doctoral thesis of Luiz Antonio dos Santos Lima, was related to abnormalities of mental character that children could present. School education was thought in a way by the potiguar thinker that it could be applied as deep as the moral, intellectual and behavioral deviations of the individual were, making use of hygiene practices of the minds through a normalizing process towards a civilized and developed future of the Brazilian nation which would manage, watch and fix the thoughts of the school students

Escarificação ácida na superação da dormência de sementes de pau ferro (Caesalpinea ferrea Mart.ex Tu. var. leiostachya Benth.)

Seeds of Caesalpinea ferrea Mart. ex Tu. var. leiostachya Benth. present low and irregular germination due to dormancy caused by the impermeability of the tegument. With the purpose to determine an efficient method to accelerate and uniformize seed germination, they were submitted to different immersion periods (0, 5, 10, 15, 20, 25 and 30 minutes) in sulfuric acid (95-98%), influence emergency and vigor (first count, speed index, medium time and relative frequency of emergency, length and dry matter of the seedlings). The experiment was carried out under greenhouse conditions with an experimental design of completely randomized, with seven treatments and four replications. The pre-conditioning of the seeds with immersion in concentrated sulfuric acid was efficient to overcoming seed dormancy, by increasing the percentage and speed emergency, the first count of emergency, length and dry matter of seedlings and reduction in the medium time for emergency. The efficiency of this chemical treatment with concentrated sulfuric depends on the immersion time, and 10 to 20 minutes were the most adequate to provide larger emergency uniformity percentages and vigor.

Complexos metálicos de cobalto, níquel e cobre com a Pirazina-2-carboxamida e 4- hidrazida ácida piridincarboxílica: síntese e caracterização

This work involved the synthesis, characterization and proposing the molecular structure of coordination compounds involving ligands pyrazine-2-carboxamide (PZA) and 4- hydrazide acidic pyridine carboxylic (INH) and metals of the first transition series (M = Co2+, Ni2+ and Cu2+). For the characterization of the compounds used were analytical techniques such as infrared absorption spectroscopy average (FT-IR) molar conductivity measurements, CHN elemental analysis, EDTA Complexometric, measurement of melting point, X-ray diffraction by powder method, Thermogravimetry (TG) and Differential Thermal Analysis (DTA) and Simultaneous Differential Scanning Calorimetry (DSC). The absorption spectra in the infrared region suggested that the ligand coordination to the metal center occurs through the carbonyl oxygen atom and nitrogen alpha pyrazine ring to those complexes formed with PZA. For INH complexes with metal-ligand coordination is through the carbonyl oxygen and nitrogen of the terminal hydrazide grouping. The conductivity measurements of the complexes in aqueous solution they suggest to all behavior of the type 1:2 electrolytes, and conduct of non-electrolytes in acetonitrile. The results obtained by CHN elemental analysis and EDTA Complexometric allowed to infer the stoichiometry of the compounds synthesized. For all of the complexes obtained was possible to record the melting points, neither of which melted near the melting temperature of the free ligands. The X-ray diffraction showed that the complexes of pyrazinamide exhibited diffraction lines, suggesting that these compounds are crystalline, while compounds of isoniazid, with the exception of cobalt, exhibited diffraction lines, indicating that they are crystalline. The results from the TG-DTA and DSC allowed information regarding the dehydration and thermal decomposition of these complexes

Caracterização e aplicação de vermicultura natural e quimicamente modificada na adsorção de azul de metileno

Chemical modification of clays has been extremely studied in the search for improvements of their properties for use in various areas, such as in combating pollution by industrial effluents and dyes. In this work, the vermiculite was chemically modified in two ways, characterized and evaluated the adsorption of methylene blue dye. First was changed with the addition of a surfactant (hexadecyltrimethylammonium bromide, BHTA) making it an organophilic clay and then by adding an acid (HCl) by acid activation. Some analyzes were performed as X-ray fluorescence (FRX), X-ray diffraction (DRX), adsorption isotherms of methylene blue dye, infrared (FTIR) , scanning electron microscopy (SEM), thermal gravimetric analysis and spectroscopy energy dispersive (EDS). Analysis by FRX of natural vermiculite indicates that addition of silicon and aluminum, clay presents in its structure the magnesium, calcium and potassium with 16 % organic matter cations. The DRX analyzes indicated that the organic vermiculite was an insertion of the surfactant in the space between the lamellae, vermiculite and acid partial destruction of the structure with loss of crystallinity. The adsorption isotherms of methylene blue showed that there was a significant improvement in the removal of dye to the vermiculite with the addition of cationic surfactant hexadecyltrimethylammonium bromide and treatment with acid using HCl 2 mol/L. In acid vermiculites subsequently treated with surfactant, the adsorption capacity increased with respect to natural vermiculite, however was much lower compared vermiculite modified with acid and surfactant separately. Only the acidic vermiculite treated with surfactant adjusted to the Langmuir model. As in the infrared spectrometry proved the characteristics of natural vermiculite. In the organic vermiculite was observed the appearance of characteristic bands of CH3, CH2, and (CH3)4N. Already on acid vermiculite, it was realized a partial destruction with decreasing intensity of the characteristic band of vermiculite that is between 1074 and 952 cm-1. In the SEM analysis, it was observed that there was partial destruction to the acid treatment and a cluster is noted between the blades caused by the presence of the surfactant. The TG shows that the higher mass loss occurs at the beginning of the heating caused by the elimination of water absorbed on the surface between layers. In the organic vermiculite also observed a loss of mass between 150 and 300 °C caused decomposition of the alkylammonium molecules (surfactants)

Monitoramento da qualidade das ásguas de chuvas conforme a atuação dos sistemas sinóticos na cidade de Natal/RN

Acid rain is a major assault on the environment, a consequence of burning fossil fuels and industrial pollutants the basis of sulfur dioxide released into the atmosphere. The objective of this research was to monitor and analyze changes in water quality of rain in the city of Natal, seeking to investigate the influence of quality on a local, regional and global, in addition to possible effects of this quality in the local landscape. Data collection was performed from December 2005 to December 2007. We used techniques of nefanálise in identifying systems sinóticos, field research in the search for possible effects of acid rain on the landscape, and collect and analyze data of precipitation and its degree of acidity. Used descriptive statistics (standard deviation and coefficient of variation) used to monitor the behavior of chemical precipitation, and monitoring of errors in measurements of pH, level of confidence, Normalized distribution of Gauss, confidence intervals, analysis of variance ANOVA were also used. Main results presented as a variation of pH between 5,021 and 6,836, with an average standard deviation of 5,958 and 0,402, showing that the average may represent the sample. Thus, we can infer that, according to the CONAMA Resolution 357 (the index for fresh water acidity should be between 6.0 and 9.0), the precipitation of Natal / RN is slightly acidic. It appears that the intertropical convergence zone figures showed the most acidic among the systems analyzed sinóticos, taking its average value of pH of 5,617, which means an acid value now, with a standard deviation of 0,235 and the coefficient of variation of 4,183% which shows that the average may represent the sample. Already in field research and found several places that suffer strongly the action of acid rain. However, the results are original and need further investigation, including the use of new methodologies

The ultrastructure of Sorubim lima (Teleostei, Siluriformes, Pimelodidae) spermatogenesis: premeiotic and meiotic periods

The ultrastructure of Sorubim lima spermatogenesis during the premeiotic and meiotic periods was studied. Our observations showed that the germ cells in the cysts are connected by cytoplasmic bridges and the mitotic and meiotic divisions are slightly asynchronous, the first and the last spermatogonial generations differ in the cellular and nuclear volume, nucleolus, chromatin condensation, distribution, size, density, and shape of the mitochondria, presence of 'lamellae anulata', amount and dimension of the 'nuages', and movement of the centrioles. In addition to the nuclear prophase structures, the spermatocyte I shows changes in all other cellular organelles and elongated vesicles appear in the cytoplasm. The accentuated cytoplasmic density and thickened walled vesicles are morphological characteristics that differentiate spermatocytes II from the other germ cells in the cysts of Sorubim lima testis.
