Hibridismo cultural: o imaginário europeu na construção da sexualidade feminina do primeiro século de colonização brasileira

The aim of this study is to investigate and analyze the conceptions of sexuality and female sexual behavior and conduct, formed from the merger of information and securities purchased under the eyes, rules and guidelines established relations with the Holy Office during his visit to Inquisitorial Brazil in the late sixteenth century. It is a survey of historical methodology in which we used as the exploratory research and literature. In the sixteenth century the Church increases the pressure to change the sexual mores that were free in the Middle Ages, a fact which influences the rules and regulations that are adopted by the Holy Office regarding the person's sex life. The first structure was based on Brazilian sexual alliance between Indians and settlers, which led to sugar, by the Portuguese, the customs of the land, which included sexual practices free since the Indians were out of Christian influence. Supported by the absence of white women, the settlers took them wives of the earth, usually more than one, creating conflict with the Jesuits who condemned Indian polygamy. In this context, in 1591, landed on Brazilian soil Heitor Furtado de Mendonca, and with it, the First Visitation of the Holy Office to investigate, arguing, exploring feelings and behaviors, to discover the true facts, finally, to demonstrate the errors Faith and punish them with the rigor of ecclesiastical law. His passing opens us to visualize traces of sexuality in the current "Tropic" a racist, misogynist world where black women and degraded land could be subject to the wishes of the white man, with whom he could mate at will. Alone and forgotten, women have not found the colony margin to denounce or to speak and were stigmatized by the look of travelers and writers have been through here.

Avaliação da capacidade de vedamento e pH do tampão apical com cimento Portland branco acrescido de radiopacificadores convencionais

The Portland cement has shown similar biological properties to calcium hydroxide, but its radiopacity is lower. Therefore, the addition of materials that minimize this deficiency should be considered. OBJECTIVE: To evaluate the apical sealing ability and pH of a white Portland cement added of several radiopacifying agents. MATERIAL AND METHODS: Forty bovine roots with incomplete apices were selected, and the foraminal openings were standardized to PM 720G bur. After the external root sealing, an apical intracanal barrier 10.0 mm thick was executed with the white Portland cement powder, pure or added of a radiopacifying agent (iodoform, zinc oxide or bismuth subnitrate), and distilled water (0.37 mL). The apical roots were immersed 24h in water in humid atmosphere, and after that they were immersed 24h in 2% Rhodamine B, under vacuum. In sequence, the roots were longitudinally sectioned, the root fragments were photographed, the images were digitalized and the apical infiltration was measured by the Image Tool program. The pH solutions were also evaluated, in 24h and 48h and 7 and 30 days. Data were submitted to Anova test. RESULTS: The zinc oxide solution has the lowest apical infiltration in relation to the other groups (p < 0.05). The pH behavior varied during the analysis, and in the period of 24h all groups showed the highest values (p < 0.05). CONCLUSION: The type of radiopacifying agent used interferes in the sealing ability of the apical barrier, and zinc oxide showed to be the most beneficial one. The pH varies according to the period of analysis, and the highest values were obtained in the first 24h (p < 0.05).

Effect of moisture on dental enamel in the interaction of two orthodontic bonding systems

OBJECTIVE: The purpose of this study was to assess by means of scanning electron microscopy (SEM) the remaining adhesive interface after debonding orthodontic attachments bonded to bovine teeth with the use of hydrophilic and hydrophobic primers under different dental substrate moisture conditions. MATERIAL AND METHODS: Twenty mandibular incisors were divided into four groups (n=5). In Group I, bracket bonding was performed with Transbond MIP hydrophilic primer and Transbond XT adhesive paste applied to moist substrate, and in Group II a bonding system comprising Transbond XT hydrophobic primer and adhesive paste was applied to moist substrate. Brackets were bonded to the specimens in Groups III and IV using the same adhesive systems, but on dry dental enamel. The images were qualitatively assessed by SEM. RESULTS: The absence of moisture in etched enamel enabled better interaction between bonding materials and the adamantine structure. The hydrophobic primer achieved the worst micromechanical interlocking results when applied to a moist dental structure, whereas the hydrophilic system proved versatile, yielding acceptable results in moist conditions and excellent interaction in the absence of contamination. CONCLUSION: The authors assert that the best condition for the application of primers to dental enamel occurs in the absence of moisture.

Análise estrutural de aerogéis via espalhamento de luz a baixo ângulo

The sol-gel process is a method for obtaining vitreous or vitro-ceramic materials which, are prepared a sol and by drying the liquid phase. This technique has been used extensively for the preparation of glassy gels, films, fibers and particles from the hydrolysis and polycondensation reactions of metal alkoxides. The usual methods for drying are: evaporation drying (xerogels), freeze drying (criogéis) and via supercritical CO2 extraction (aerogels). In the present work, we studied the preparation of silica gels by the sol-gel process from the hydrolysis of alkoxides tetraethylorthosilicate (TEOS) and 3-glycidoxypropyltrimethoxysilane (GPTS). The hydrolysis was promoted from GPTS and TEOS in proportion (4: 1) under acidic conditions. The hydrolysis reaction was promoted inside a Becker at room temperature. After hydrolyses the prepared sol had pH 2, and kept under mechanical agitation for a period of 1 hour. In order to accelerate the polycondensation reaction, the pH was corrected to a value near 5 by slowly adding NH4OH. Then the sols were leaked in sealed polycarbonate containers and maintained for 20 days at 40°C for gelation. Silica aerogels were prepared via supercritical CO2 extraction of the wet gel at temperature and pressure higher than 31°C and 74 atm, in an autoclave specially developed for the process. The structural characteristics were studied in the dry gel (aerogel). Aerogels were then characterized by nitrogen adsorption and small angle light scattering. The nitrogen adsorption data were analyzed for the determination of the BET specific surface (SBET), the total pore volume Vp, the pore mean size (lP=4Vp/SBET), the particle mean size (lS) and the pore size distribution (PSD). And the data from small angle light scattering were analyzed to determine the correlation function (γ'), the area per unit volume (S/V), average pore size (l ) and the average particle size...

Análise dos métodos de leira estática e de revolvimento manual na compostagem de resíduos orgânicos gerados em restaurante universitário

Composting is considered a process that enables adding value to organic solid waste turning them into organic fertilizer. In this process, factors such as mishandling the windrow, failed to control the temperature, aeration and moisture content will result in the quality of waste decomposition, and thus affect the quality of the final compound. Decentralized systems such as home composting, composting in restaurants, food courts and schools are one of the solutions for valuing these waste in a non expensive way and with greater quality. For this purpose, the project aims to analyze the conditions for composting of solid waste of the University Restaurant of Rio Claro- SP, through two different composting systems: manual revolving windrow and static pile. It was found that in University Restaurant (RU) on average 33% by weight of the total waste generated in the property are capable of composting. In this sense, in order to investigate the preliminary process operation parameters were mounted one manual windrow composed of 100% of the UR waste and a static pile composed of 60% of the UR waste and 40% of pruning and grass residues (PG). This study analyzed the manual revolving windrow and static pile systems for the parameters: moisture content, pH, C / N ratio and temperature. The study of the proportions of the PG and UR waste pointed to the need for pruning and grass residues addition for composting, considering that the manual revolving windrow composed by 100% of the UR waste had no satisfactory performance due to low temperatures measured during 60 days analysis. The best ratio for manual revolving windrow method analyzed in this study was 60% of the UR waste and 40% of PG waste, in dry weight. From this proportion a static pile was assembled, composed of 60% of UR waste e 40% of PG waste from the maintenance activities of the green area of the university. The biological activity in the static pile reached the maximum temperature of ...

Storage media for avulsed teeth: a literature review

Dental avulsion is the most severe type of traumatic tooth injuries because it causes damageto several structures and results in the complete displacement of the tooth from its socketin the alveolar bone. The ideal situation is to replant an exarticulated tooth immediatelyafter avulsion because the extraoral time is a determinant factor for treatment successand for a good prognosis. However, it is not always possible. The success of replantationdepends on a number of factors that may contribute to accelerate or minimize theoccurrence of root resorption or ankylosis, among which is the type and characteristicsof the medium used for temporary storage during the time elapsed between avulsionand replantation. Maintaining the tooth in an adequate wet medium that can preserve,as longer as possible, the vitality of the periodontal ligament cells that remain on rootsurface is the key to success of replantation. Recent research has led to the developmentof storage media that produce conditions that closely resemble the original socketenvironment, with adequate osmolality (cell pressure), pH, nutritional metabolites andglucose, and thus create the best possible conditions for storage. Although these storagemedia can now be purchased in the form of retail products, the most common scenariois that such a product will not be readily available at the moment of the accident Thispaper reviews the literature on the different storage media that have been investigatedfor avulsed teeth based on full-length papers retrieved from PubMed/Medline, Lilacs, BBOand SciELO electronic databases using the key words storage medium , transportationmedium , avulsion , tooth avulsion , replantation , tooth replantation , milk and propolis .After application of inclusion and exclusion criteria, 39 papers were selected and criticallyreviewed with respect to the characteristics, efficacy and ease of access of the storagemedium.

Avaliação da infiltração marginal de três cimentos endodônticos após preparo para retentor de acordo com o momento do preparo

Objetivo: o objetivo desse estudo in vitro foi avaliar a infiltração marginal coronária após o preparo para retentor em dentes obturados com três diferentes cimentos, de acordo com o período entre a obturação do canal radicular e o preparo para retentor. Métodos: Noventa dentes humanos recentemente extraídos foram limpos e instrumentados e, então, obturados com Sealapex, Endométhasone ou TopSeal. Brocas Gates-Glidden foram utilizadas para o preparo imediato de 10 dentes de cada cimento até manter 5mm de obturação remanescente. Sessenta raízes obturadas foram incubadas a 37°C em meio úmido por 30 e 60 dias para serem, depois, preparadas para os retentores como descrito anteriormente. A superfície externa de cada raiz foi coberta com Araldite. Os espécimes foram imersos em corante azul de metileno a 2% sob vácuo por 24h, para então poderem ser analisados. A infiltração foi mensurada pelo software Sigma Scan da parte superior da obturação à porção apical alcançada pelo corante. Resultado: o Sealapex e o TopSeal apresentaram menor infiltração após o preparo para retentor do que o Endométhasone. O preparo imediato para o retentor apresentou menor infiltração do que o preparo para o retentor após 30 e 60 dias da obturação do canal radicular.

Efeito da umidade no esmalte dental na interação de dois sistemas de colagem ortodôntica

Objetivo: a proposta desse estudo foi avaliar, por meio de microscopia eletrônica de varredura (MEV), a interface adesiva após a descolagem de acessórios ortodônticos, fixados em dentes bovinos com emprego de adesivo hidrofílico e hidrofóbico, em condições distintas de umidade do substrato dentário. Métodos: foram utilizados 20 incisivos inferiores, divididos em quatro grupos (n = 5): Grupo I , empregou-se o sistema de colagem contendo o primer hidrofílico Transbond MIP e a pasta adesiva Transbond XT, aplicados em substrato úmido; Grupo II, empregou-se o sistema de colagem primer hidrofóbico Transbond XT e pasta adesiva em substrato úmido; Grupos III e IV, os braquetes foram colados com os mesmos sistemas de união dos Grupos I e II, porém com esmalte dentário seco. Removidos os acessórios, avaliou-se em MEV, em diferentes magnificações, a interface adesiva e a interação dos sistemas adesivos com o esmalte dentário. As imagens foram avaliadas qualitativamente, observando-se o embricamento mecânico para o adesivo hidrófilo em quaisquer condições de substrato. Resultados: a falta de umidade no esmalte condicionado permitiu uma melhor interação entre os materiais de ligação e a estrutura adamantina. O adesivo hidrofóbico apresentou o pior resultado de interação micromecânica quando aplicado a uma estrutura dentária úmida; já o sistema hidrofílico mostrou-se versátil, obtendo resultados aceitáveis em condições de umidade e excelente interação na ausência de contaminação. Conclusão: os autores afirmam que a melhor condição do esmalte dentário para a aplicação de primers é com a ausência de umidade.
