Journal of Behavioral and Brain Science (JBBS) , 2018, DOI: 10.4236/jbbs.2018.810034
Abstract: Research has shown that dissatisfied couples in the relationship commonly exhibit facial expressions of contempt in interactions. At this point, based on the study of cognition and physiology, researchers were able to predict by longitudinal studies the probability of divorce in a marriage, with accuracy of up to 94%. Our objective was to investigate whether the occurrence of facial expressions of disgust and contempt in married women is associated with marital dissatisfaction. This is an experimental study that correlated, through filmed interviews, the frequency of facial expressions of disgust and disgust (Facial Action Coding System) to the Marital State’s Golombok Rust Inventory, in a sample composed of 20 women. Data analysis based on the Spearman Correlation Test showed a positive correlation between facial expressions of disgust and disdain and conjugal dissatisfaction (rs = 0.2198, p = 0.0280), corroborating the data in the literature.
DECIFRA-ME OU TE DEVORO: O PENSAMENTO SOBRE A POESIA EM POEMAS DE FRANCISCA JúLIA
Maiara Knihs
Fólio : Revista de Letras , 2011,
Abstract: The poetry of Francisca Júlia da Silva is read and the parnassian poetry in general as a very formally precise poetry. This rigorous measurement of poetic forms is the axis upon which the critic relies to valorize it, as it’s Jo o Ribeiro case who understands this formal cares as the richness of her poetry, or to dismiss it, as is Mario de Andrade’s case, who understands this formal accuracy as excess, as pure artificiality, to the point of disregarding her poems as poetry. This essay however proposes a poetry reading not merely as a form, but as a force or plurality of forces. Thus, it seeks to analyze the anachronic force witch cohabitates there. The force of Francisca Júlia’s marble monuments resides in the cracks left there by time, that is, in the creation of thought, of poetry. This poetry is a modern poetry because it brings a critical thinking about language and allied to the hierarchization loss of the subject-object relationship: here, the Venus descends from the throne and gets face to face with the I, an I already emptied and therein lies her force.

International Journal of Electrochemical Science , 2007,
Abstract: A sensitive sensor for the determination of hydrogen peroxide was fabricated based on the enhanced response of the analyte at glassy carbon surfaces modified by a film of Co(II) hexacyanoferrate. Increased chemical stability of the film was gained by incorporation of ruthenium (III) ions. Following the optimization of the experimental conditions for the film deposition, the RuCoHCF modified electrode presented excellent analytical properties toward hydrogen peroxide with a low limit of detection (2.8 mmol L-1), a large dynamic concentration range (10 – 500 mmol L-1) and a very short response time (t100% = 6.3 s for 0.02 mmol L-1 hydrogen peroxide). The usefulness of the proposed RuCoHCF electrochemical sensor was confirmed by monitoring the consumption of hydrogen peroxide during photodegradation reactions of an azo dye compound (Remazol Black B) present in wastewater samples.

Abstract: O objetivo do presente trabalho foi avaliar a frequência e número absoluto de linfócitos B e das subpopula es de linfócitos T em bovinos infectados pelo vírus da leucemia bovina (BLV) com distintos perfis leucocitários conhecidos como n o leucêmicos (AL) e com linfocitose persistente (LP). Deste modo, 15 animais foram selecionados e divididos uniformemente em três grupos (negativo, AL e LP). A infec o pelo vírus da BLV foi detectada por imunodifus o em ágar gel e por ensaio imunoenzimático. A quantifica o das popula es de linfócitos B e T foi determinada por citometria de fluxo utilizando anticorpos monoclonais. Os resultados do presente estudo apontaram para aumento da popula o de linfócitos B, e também das células CD5+ e CD11b+, que geralmente s o alvo da infec o pelo vírus da BLV, nos animais com LP. Consequentemente pode-se observar redu o da porcentagem de linfócitos T, T CD4+ no sangue periférico, e de linfócitos T, T CD4+ e T CD8+ nas células mononucleares do sangue periférico isoladas por gradiente de centrifuga o. No entanto, nenhuma altera o no número absoluto de linfócitos T, T CD4+ e T CD8+ no sangue periférico foi encontrada nos animais manifestando LP. Entretanto, encontrou-se correla o alta e significativa entre o número absoluto de linfócitos T e T CD8+ e o número absoluto de linfócitos B no sangue periférico nos animais manifestando LP, n o encontrando a mesma correla o com os linfócitos T CD4+. Além disso, n o foram observadas correla es significativas entre o número absoluto de linfócitos T, T CD4+ e T CD8+ e o número absoluto de linfócitos B no sangue periférico nos animais AL e negativos. The aim of the present trial was to determine the frequencies and absolute number of B and T lymphocytes subpopulations in bovine leukemia virus (BLV)-infected dairy cows with distinct lymphocyte profile known as non-leukemic (AL) and persistent lymphocytosis (PL). Thus, 15 animals were selected and divided uniformly in three groups (negative, AL, PL). The BLV infection was detected by agar gel immunodiffusion and enzyme-linked immunosorbent-assay. The lymphocytes subsets were evaluated using monoclonal antibodies by flow cytometry. The results of the present study pointed out to an increase in B lymphocytes, and also an augment in CD5+ and CD11b+ cells in animals showing PL. Consequently, it can be observed a decrease in the percentage of T cells subsets in these animals. Conversely, no significant alterations in the absolute number of the T lymphocytes, T CD4+ cells and T CD8+ lymphocytes were found in BLV-infected dairy cows with PL.
