O experimento foi conduzido com o objetivo de avaliar os pesos e porcentagens de órgãos em relação ao peso vivo ao abate (PVA), ao peso de corpo vazio (PCV) e ao peso total dos órgãos (PTO) de cordeiros inteiros 1/2 Ile de France 1/2 Ideal confinados, recebendo dietas com relações volumoso:concentrado de 50:50 e 30:70 e abatidos aos 30 ou 34 kg. Os parâmetros mensurados foram: língua, pulmões com traquéia, coração, fígado, pâncreas, timo, tireóide, adrenal, rins, testículos, baço, diafragma, bexiga, pênis e glândulas anexas. Os resultados obtidos revelaram diferenças entre os pesos ao abate nas porcentagens de língua, coração, pulmões com traquéia, diafragma, pâncreas, tireóide, baço e glândulas anexas em relação ao PVA; nas porcentagens de língua, pulmões com traquéia, fígado, pâncreas, baço e glândulas anexas em relação ao PCV e nas porcentagens de pulmões com traquéia, fígado, pâncreas, tireóide, baço e glândulas anexas em relação ao PTO. Dietas com diferentes relações volumoso:concentrado afetaram apenas as porcentagens de pâncreas em relação ao PVA, ao PCV e ao PTO. Verificaram-se interações entre relação volumoso:concentrado e peso vivo ao abate nos pesos dos pulmões com traquéia, fígado, pâncreas, tireóide e glândulas anexas.

Foram estudados tumores de mama em cadelas, comparando o seu padrão citológico, obtido através da Citologia Aspirativa por Agulha Fina (CAAF), com os resultados da histopatologia. Num período de um ano, as cadelas trazidas ao Hospital Veterinário -- UNESP -- Câmpus de Jaboticabal foram submetidas a exérese cirúrgica dos tumores mamários. As amostras foram avaliadas de acordo com parâmetros estruturais utilizados nos tumores mamários humanos, como grau de atipia, critérios nucleares, padrão de cromatina e nucléolos, alta celularidade e pouca coesão intercelular. Utilizaram-se estes critérios para diferenciar tumores mamários benignos de malignos com 63% de diagnósticos concordantes, sensibilidade de 73% e especificidade de 83%. Nossos dados mostraram ter uma correlação positiva com o prognóstico, demonstrando que é possível reconhecer variáveis estruturais de malignidade na citopatologia para obter um diagnóstico precoce e um prognóstico seguro.

The study research case with a quantitative approach and prospective data, carried out between December 2010 and February 2011 with the aim of identifying the profile of women in the study, to characterize the acts of violence in the type, frequency, location occurrence and aggressor, analyze the steps taken after the occurrence of acts of violence and the main consequences on the victims. The population consisted of 285 workers in a tertiary institution in Rio Grande do Norte. The results showed that 99 (34.74%) have between 51 to 60 years of age, 78 (27.37%) of 41 to 50 and 62 (21.75%) between 20 and 30 years, are considered color white, 162 (56.84%) have completed higher education, 171 (60.00%) and of these 97 (56.73%) reported having some post-graduate degrees, are married, 141 (49.47%) and have from zero to one child, 148 (51.93%) reside in the south of the city of Natal, 146 (51.23%) have a monthly income of three to five minimum wages, 171 (60.00%) and are mostly in the Technical Administrative Sciences 152 (53.33%), 77 (27.02%) reported having experienced violence, 60 (62.50%) episodes of verbal aggression, 26 (27.08%) of bullying , 05 (5.21%) of physical abuse and 05 (5.21%) sexual harassment; 05 (100.00%) assaults were made by the spouse or partner of the victims and co-workers is another profession were responsible for 18 (30.00%) verbal aggression, 15 (57.69%) bullying and 03 (60.00%) sexual harassment, 02 (40.00%) of victims of physical aggression and 18 (30.00 %) of verbal abused only once, 10 (38.46%) of bullying and 02 (40.00%) of sexual harassment experienced four or more times 05 (100.00%) assaults occurred at domestic and work stood out with 36 (60.00%), verbal abuse, 22 (84.62%), moral harassment and 04 (80.00%) sexual harassment, 35 (36.46%) told colleagues work and 31 (32.29%) for family and friends in 75 (78.13%) cases there was no intervention, 07 (7.29) were unable to respond if something had been done and 14 (14.58% ) have been reported intervention of these, 09 (64.29%) were taken by the heads of the victims, 26 (32.10%) did not notify the fact on the ground that no action would be taken, 62 (80.52%) felt stress , 5 (1.76%) of women turned away from work after the episode of violence, accounting for 198 days of absenteeism. It is concluded that there is a high rate of violence against women, even when they have a good socioeconomic status, and in this sense is important to establish bases of new proposals for improving control of cases of health professionals, especially nurses, to approach patients with a more investigative, and that by identifying a case of violence, be instructed about the paths to be followed for notification while providing psychological support to victims.

Análogos do hormônio juvenil (AHJ) têm sido testados como reguladores de crescimento de Bombyx mori L., com vistas ao incremento da produção de casulos. Esses produtos, quando aplicados em doses adequadas, prolongam o período larval. Os efeitos da aplicação de AHJ podem variar com o produto, a linhagem e o momento de aplicação. Este estudo teve por objetivo avaliar o efeito da aplicação tópica, em diferentes momentos, de três análogos do hormônio juvenil sobre o crescimento dos insetos e a produção de seda da linhagem brasileira C115xN108 do bicho-da-seda. Os produtos piriproxifem, metoprene e fenoxicarbe foram aplicados em larvas do bicho-da-seda a 24h, 48h, 72h e 96h após o início do quinto ínstar (HQI) e seus efeitos sobre características biológicas larvais e adultas e a produção de seda foram avaliados. Independentemente do momento de aplicação, os três produtos afetaram todos os parâmetros avaliados. A reserva de nutrientes acumulada durante o período larval prolongado dos insetos tratados foi destinada ao crescimento das glândulas sericígenas e, também, convertida em peso corporal, com conseqüentes incrementos na produção de seda. Aplicações entre 48 e 72 HQI provocaram os maiores incrementos na biomassa e na produção de casulos de B. mori. Variações no momento de aplicação de 24h e 96h não influenciaram a emergência ou a oviposição de adultos de B. mori, nem a viabilidade dos ovos.

This work proposes the specification of a new function block according to Foundation Fieldbus standards. The new block implements an artificial neural network, which may be useful in process control applications. The specification includes the definition of a main algorithm, that implements a neural network, as well as the description of some accessory functions, which provide safety characteristics to the block operation. Besides, it also describes the block attributes emphasizing its parameters, which constitute the block interfaces. Some experimental results, obtained from an artificial neural network implementation using actual standard functional blocks on a laboratorial FF network, are also shown, in order to demonstrate the possibility and also the convenience of integrating a neural network to Fieldbus devices

Discutem-se os tipos de Violência Sexual (VS) sofridos na infância e/ou adolescência e suas vicissitudes, nas trajetórias sexuais de 236 adolescentes, de ambos os sexos, cursando o Ensino Médio no interior do Oeste Paulista que declararam ter sofrido um ou mais tipos de violência sexual. Dentre esses tipos, destacamos a Violência Doméstica Sexual (VDS), aqui definida como intrafamiliar. Nesse caso, observamos que, dentre os 236 adolescentes com histórico de VDS, 94 (39.8%) declararam ter pensado em suicídio e 39 (16.5%) disseram ter tentado, sendo que 35 (89.7%) deles se declararam heterossexuais (27 [77.1%] do sexo feminino) e 4 não-heterossexuais (3 bissexuais e 1 outro, sendo todos do sexo feminino). A maioria das vítimas finda por relatar o ocorrido aos amigos e responsáveis, mas pouco ou nada é feito, em termos de medidas protetivas a elas.

Violência sexual contra crianças não é um evento incomum; no entanto, há a dificuldade de denúncia, pois, além do estabelecimento da relação de dominação que o agressor exerce sobre a vítima, a maneira como tal fato é recebido pela sociedade e como é encaminhado pelas instituições judiciárias responsáveis também é determinante para as omissões. Inserida no universo dos interrogatórios, muitas vezes, a criança causa confusão ao desmentir o que havia falado antes, reforçando possíveis preconceitos em relação a si mesma. O presente trabalho traz a análise das relações entre a infância e a instituição judiciária, com principal enfoque no sistema de comunicação e de notificação dos crimes sexuais contra a criança e as consequentes intervenções profissionais que buscam a validação, ou não, de seu testemunho. Para tanto, foram pesquisados 51 processos judiciais, dos quais foram selecionados dois casos exemplares. Este trabalho evidencia a possibilidade de preservar a criança da revitimização causada pela multiplicidade de interrogatórios, sem deixar de cumprir as normas jurídicas necessárias. A fragilidade da palavra da criança está na forma como é acolhida pelos adultos, desde a revelação na família até a denúncia aos órgãos oficiais, revelando a urgência de alterações nos procedimentos judiciais relacionados a essa problemática

Portuguese Poet Florbela Espanca (1984 1930) lived and produced her literary work during a period in which, on the one hand, the ideals of an innovative and irreverent movement were being fomented led by Fernando Pessoa, Almada Negreiros and Mário de Sá-Carneiro , on the other hand, Portugal was still dominated by a conservative and authoritarian thought, anchored in a bourgeois-christian ideology. Inserted in an unfavorable social context to the expression of the female sexual impulse, poet Florbela then appears with an innovative speech as threatening the sexual organization of the Portuguese society. This way, considering the relations between the poetic text and the historical-social context, the aim of this work is to present a reading upon the Eroticism in The Flowering Heath (2005) as a way to contravene the borders given to the sexual phenomenon. For this reason, we will mainly resort to the concepts developed on the approach of Georges Bataille The Eroticism (2004) and also by Octavio Paz The Double Flame: Love and Eroticism (2001)

This work aims to present the foundations of Kantian ethics concerning to moral judgments about sexual practices. It shows that the sexual act, for the philosopher, inevitably degrades individuals who are taking part of it, given its objectifying nature, manifested in the usage of individuals as mere means to obtain pleasure. To solve this quandary of nature since humanity is an end in itself, by the virtue of being bearer of rationality and cannot, therefore, be treated as mere means Kant claims that marriage is morally the appropriate locus for the exercise of sexuality, given the reciprocity forged there, preventing degradation. In marriage, the bond established between the impulse of nature to the conservation of the species achieved through the sexual intercourse opened to procreation and the duty of man in regarding himself as an animal being preserving the species without degrading the person is accomplished in a fully moral way. This text clarifies that the justification for the assumption of this solution is fixed at two developments of the categorical imperative: the formulas of the law of nature and humanity. Despite the fact the first brings significant contributions to human relations through the concept of reciprocity, the second establishes a normative role for the teleological argument of sexuality, becoming an obstacle in kantian's practical philosophy. To overcome that obstacle, we outline a critics which relies on the studies of Michel Foucault about sex and the power techniques related to them, producer of a scientia sexualis in the Western, demonstrating that the moral of the philosopher from Königsberg is also present in this project somehow. Finally, in a foucaultian's reading of kantian Aufklärung, we recognize that, to propose new ethical possibilities of the experience of sexuality, it is necessary to think and create new relational spaces in which the subject takes autonomously the government of self.

A padronização de um fitoterápico é etapa imprescindível para garantia da qualidade de medicamentos contendo plantas medicinais. Objetivou-se padronizar Syzygiam cumini (L.) Skeels e para tanto se estabeleceram parametros tais como, avaliação morfoanatômica das folhas, morfológica das flores e dos frutos, avaliação granulométrica da droga rasurada (frutos), determinação da umidade, avaliação dos processos de secagem, determinação do teor de extrativos e do teor de taninos (monômeros e polimeros). O estudo anatômico das folhas revelou a inexistência de pêlos no sistema dérmico, assim como a ocorrência de glândulas secretoras, drusas, colênquima e esclerênquima. As flores são hermafroditas, com androceu polistêmone e gineceu com ovário ínfero, gamocarpelar, bilocular com placentação axial. Observou-se elevado teor extrativo (38,57%). O diâmetro médio de partícula dos frutos secos moídos ficou em 0,630 mm. O processo de secagem dos frutos influenciou o teor de taninos totais. O teor de taninos determinado ficou em 5,10% para monômeros e 11,30% para os polimeros.

Glandular atrophy is one of several alterations which can aflict the salivary glands, caused generally by obstructive lesions such as sialo1ithiasis, infections or compression by neoplastic processes arnong others. In this work, a morphological and immunohistochemical study was carried out in rat parotid glands, which were submitted to obstruction of the main excretory duct suffering atrophy at varied time intervals, with the aim of appraising the behavior of myoepithelial cells during the process of glandular atrophy. It was analized the immunohistochemical expression of calponin which detects myoepithelial cells in the parotids of 28 animaIs, which were divided into 7 groups, each one made up of 4 rats, afier the ductal ligature procedure, in the following time intervals: zero hour (control), 24 hours, 7, 15, 21, 30 and 60 days. Analysis of the immunohistochemicaI profile was carried through in which the calponin expression was veritied through its distribution pattem and numericaI index. All specimens exhibited positivity for calponin in myoepithelial cells which were distributed around the acini and the ductaI structures, a small number of positiveIy marked cells being detected in the controI group and in the 24-hour group when compared to subsequent ones, where it was perceived a Iarge increase in the number of positiveIy marked cens, mainly surrounding the ductiform structures which originated during the obstruction time. Upon application of statistical tests it was verified that the rise in the number the myoepithelial positive cells for calponin, when the control groups (zero hour) was compared to the 7, 15,21, 30 and 60-day groups afier obstruction, was statistica1ly significant. It was concluded then that the detected rise probably carne about due to an elevation in the rate of proliferation of the myoepitheliaI cells subsequent to the ductal obstruction, associated with a growing resistance of these cells to glandular atrophy.

Mate choice is a component of sexual selection. Trying to understand the patterns of this process, several studies have emphasized the adaptive value of sexual differences and their influence on the assessment of the market value. The pattern for adults presented on the scientific literature, which is based on the preference for certain characteristics, shows that men search a partner who shows high value of fecundity and fertility, thus looking for partners with the ability of being pregnant and nursing their offspring. On the other hand, women look for partners with high socioeconomic status, which is strongly associated with the ability to protect and provide resources for them and their offspring. Surprisingly, there is few works that investigated the mate choice patterns during the beginning of the period of sexual differentiation on the morphological, physiological and behavioral traits. The aim of this study was to investigate mate choice patterns in adolescence in order to describe their preferences and contribute to the understanding of human reproductive behavior. Took part of this research 1,232 students from educational institutions of Natal, Brazil, and visitors to the Scientific, Technological and Cultural Fair UFRN. In the Experimental Study 1, we applied a questionnaire to evaluate the importance of certain characteristics, assessed the degree of romantic involvement and real and ideal partners age preference. In the Experimental Study 2, we did a survey of characteristics considered relevant and evaluate the importance of these characteristics in mate choice. The Experimental Study 3 brought an investigation of mate choice patterns based on self-assessment of adolescents, evaluating ideal partner for a short-term and long-term relationships and actual partner. We found that adolescents are motivated to live romantic experiences. We also observed a preference for partners of similar age to that described for adults. Finally, we found similarities and differences in the preferences for characteristics in real and ideal partners in relation to the adult pattern. In addition, we observed high similarity on the self-assessment and assessment of real and ideal partners. We suggest that in the mate choice, adolescents are similar to young adults in some aspects but not all. Our results show the relevance of the reproductive behavior investigation in this human developmental period and reinforce that further studies should contribute to the understanding of human behavior in terms of ontogenetic development and their evolutionary history.
