O internato escolar O Ateneu: produção de subjetividade na instituição total

Dans cet article on cherche à identifier les effets de l'institutionnalisation dans la production de la subjectivité dans un établissement scolaire total. La recherche est basée sur le roman «O Ateneu » de Raul Pompeia, analysé à partir de la théorie de Goffman (1961-1987) relative aux institutions totales. on décrit l itinéraire moral que le personnage Sergio développe, à son entrée à l'internat, évoquant les vicissitudes par lesquelles il passe dans ce contexte institutionnel : période d'adaptation, crises évolutives, initiations sexuelles, problèmes de rivalités, etc. les établissements totaux semblent s'organiser d'une façon caractéristique et fonctionner de manière autonome. on pourra comprendre les problèmes sociaux et les effets sur la subjectivité produite par les institutions totales par l étude des relations de pouvoir subjacentes à ces types d'établissements. Le temps pendant lequel un individu vit comme interné peut laisser des marques profondes dans sa subjectivité et se configure comme un thème personnel approprié.

Enhanced corrosion resistance of AISI H13 steel treated by nitrogen plasma immersion ion implantation

Electrochemical corrosion measurements of AISI H13 steel treated by Pill process in 3.5% (wt) NaCl solution were investigated. So far the corrosion behavior of AISI H 13 steel by Pill has not been studied. The electrochemical results are correlated with the surface morphology, nitrogen content and hardness of the nitride layer. Ion implantation of nitrogen into H 13 steel was carried out by Pill technique. SEM examination revealed a generalized corrosion and porosity over all analyzed sample surfaces. Penetration of nitrogen reaching more than 20 gm was achieved at 450 degrees C and hardness as high as 1340 HV (factor of 2.7 enhancement over standard tempered and annealed H 13) was reached by a high power, 9 h Pill treatment. The corrosion behavior of the samples was studied by potentiodynamic polarization method. The noblest corrosion behavior was observed for the samples treated by PIII at 450 degrees C, during 9 h. Anodic branches of polarization curves of PIII processed samples show a passive region associated with the formation of a protective film. The passive region current density of PIII treated H13 samples (3.5 x 10(-6) A/cm(2)) is about 270 times lower than the one of untreated specimens, which demonstrates the higher corrosion resistance for the Pill treated H 13 samples.

Reflexões sobre a anticoncepção na adolescência no Brasil

Faz-se uma reflexão sobre a contracepção e suas conseqüências na adolescência, baseada em trabalhos nacionais e internacionais alertam para a precocidade do início da atividade sexual, a qual expõe os adolescentes aos riscos da gravidez e das doenças sexualmente transmissíveis e AIDS. Verifica-se que a maioria dos adolescentes recebe informações sobre contracepção, sendo a pílula e o preservativo os mais conhecidos e utilizados. Porém, registram-se elevada inadequação na utilização dos métodos contraceptivos, além da falta de serviços assistências, onde possam buscar orientações e atendimento. Tal realidade alerta para a necessidade de maior envolvimento de profissionais da saúde, da educação, família e comunidade, garantindo qualidade de vida aos adolescentes.

Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)

Cultura pedagógica e formação de professores: a biblioteca da escola normal de Piracicaba (1911-1920)

Cet article a pour objet la Bibliothèque de l'École Normale de Piracicaba, à l'intérieur de São Paulo, entre les années 1911 et 1920, parce qu'elle représente un lieu de formation d'enseignants et organisation de culture pédagogique. Cette Bibliothèque qui a été constituée au long du cycle de vie de l'École Complémentaire de Piracicaba (1896-1911) et officialisée à partir de 1911 aura le rôle d'organiser et disséminer une certaine culture pédagogique en raison de sélectionner, trier et distribuer un ensemble de connaissances propres à la profession enseignante. Elle symbolise un espace de formation de l'enseignant de l'École Normale et de l'élève-lecteur. L'étude de la culture pédagogique se concentre sur l'analyse de cette bibliothèque.

Use of vaccine and probiotic in the control of swine diarrhea caused by enterotoxigenic Escherichia coli

A total of 42 pregnant sows were divided into eight groups and submitted to the following treatments: group I with seven unvaccinated sows whose piglets did not receive probiotic, was used as control, group II with five vaccinated sows whose piglets did not receive probiotic, groups III, IV and V with five vaccinated sows each whose piglets received probiotic for 5, 15 and 28 days, respectively, and groups VI, VII and VIII with five unvaccinated sows each whose piglets received probiotic for 5, 15 and 28 days, respectively. Each animal in the vaccinated groups received subcutaneously Two doses of 5.0ml of vaccine containing pill K88, K99, 987P and F42 of Escherichia coli. The probiotic contained Lactobacillus acidophilus at the dose of 2.0x10(8) live cells in 20ml of milk and was administered orally. All animals were observed clinically and bacteriologically and the titers of anti-K88, anti-K99, anti-987P and anti-F42 antibodies were determined in serum and colostrum. The results showed that the vaccine associated to the probiotic administered for 28 days was the most effective treatment for the control of diarrhea caused by enterotoxigenic Escherichia coli.

Clinical assessment of ethinylestradiol and cyproterone acetate in menstrual irregularities of hyper-androgenic origin

We report on the results of a double-blind, randomized, controlled clinical trial comparing two preparations of ethinylestradiol and cyproterone acetate in the treatment of women of reproductive age presenting menstrual irregularities of hyper-androgenic origin. After obtaining informed consent, subjects were randomized to a 4-month treatment period consisting of one daily dose of 0.035mg ethinylestradiol + 2mg cyproterone acetate. The treatment regimen cycle consisted of one pill, once daily for 21 days, followed by a 7-day pill-free period. We compared the efficacy of two presentations of the drug combination after each treatment cycle (Visits 2, 3, 4, and 5) in establishment and maintenance of menstrual regulation, intensity of menstrual flow, and dysmenorrhea, as well as a comparison of the two presentations in terms of Global Satisfaction and Drug Satisfaction assessments performed by the patients and the investigating physician. At each study visit, drug compliance and use of concomitant medications, as well as incidence, severity and duration of adverse events were recorded. A total of 86 subjects were randomized to treatment, with 43 subjects in each treatment group. At Visit 2 and each subsequent visit, all patients in both treatment groups reported an episode of withdrawal bleeding during the 7-day hormone-free period. We observed a statistically significant (p<0.0001) decrease in the incidence of dysmenorrhea at each study visit in relation to the pretreatment assessment. There was a significant reduction (p<0.0001) in the number of subjects reporting intermenstrual bleeding at each study visit in both treatment groups. Global Satisfaction scores by the patient and physician increased significantly at each successive study visit in both treatment groups. There were no clinically significant changes in vital signs, weight, and body mass index throughout the study period in either group. The number of subjects reporting adverse events at each visit did not vary between treatment groups. The combined oral contraceptive pill containing ethinylestradiol and cyproterone acetate was found to be both effective and safe in the menstrual irregularities of hyper-androgenic origin (amenorrhea, dysmenorrhea, and intermenstrual bleeding) assessed in this study. © Copyright Moreira Jr. Editora.

Cytogenetic analysis in Thoracocharax stellatus (Kner, 1858) (Characiformes, Gasteropelecidae) from Paraguay river basin, Mato Grosso, Brazil

Thoracocharax stellatus (Characiformes, Gasteropelecidae) is a small Neotropical species of fish, widely distributed in several rivers of South America. Evidence for karyotype heteromorphysm in populations from different geographical regions has been reported for this species. In this way, populations of T. stellatus from the Paraguay River basin were cytogenetically characterized and the results were compared with other studies performed in the same species but from different basins. The results showed a diploid number of 2n = 54 for T. stellatus, with chromosomes arranged in 6 metacentric (m), 6 submetacentric (sm), 2 subtelocentric (st) and 40 acrocentric (a), for both sexes, with a simple Nucleolus Organiser Region (NOR) system reported by the techniques of silver nitrate impregnation and fluorescent in situ hybridisation (FISH) using 18S rDNA sequences as probe. The distribution of constitutive heterochromatin, observed by the C-band technique and Chromomycin A3 staining showed great similarity among the analyzed populations and consists mainly of discrete blocks in the pericentromeric and telomeric regions of most chromosomes. The presence of female heterogamety was alsoobserved indicating a ZZ/ZW system with W chromosome almost totally heterochromatic. The results also show cytogenetic diversity of the group and are useful to understand the mechanisms of karyotype evolution of the family. © Edson Lourenço da Silva et al.

High chromosome variability and the presence of multivalent associations in buthid scorpions

In this study, we investigated the mitotic and meiotic chromosomes of 11 Buthidae scorpion species, belonging to three genera (Ananteris, Rhopalurus and Tityus), to obtain detailed knowledge regarding the mechanisms underlying the intraspecific and/or interspecific diversity of chromosome number and the origin of the complex chromosome associations observed during meiosis. The chromosomes of all species did not exhibit a localised centromere region and presented synaptic and achiasmatic behaviour during meiosis I. Spermatogonial and/or oogonial metaphase cells of these buthids showed diploid numbers range from 2n = 6 to 2n = 28. In most species, multivalent chromosome associations were observed in pachytene and postpachytene nuclei. Moreover, intraspecific variability associated with the presence or absence of chromosome chains and the number of chromosomes in the complex meiotic configurations was observed in some species of these three genera. Silver-impregnated cells revealed that the number and location of nucleolar organiser regions (NORs) remained unchanged despite extensive chromosome variation; notably, two NORs located on the terminal or subterminal chromosome regions were commonly observed for all species. C-banded and fluorochrome-stained cells showed that species with conspicuous blocks of heterochromatin exhibited the lowest rate of chromosomal rearrangement. Based on the investigation of mitotic and meiotic cells, we determined that the intraspecific variability occurred as a consequence of fission/fusion-type chromosomal rearrangements in Ananteris and Tityus species and reciprocal translocation in Rhopalurus species. Furthermore, we verified that individuals presenting the same diploid number differ in structural chromosome organisation, giving rise to intraspecific differences of chromosome association in meiotic cells (bivalent-like elements or chromosome chains). © 2013 Springer Science+Business Media Dordrecht.

Amorphous silicon carbonitride films modified by plasma immersion ion implantation

Amorphous silicon carbonitride (a-SiCN:H) films were deposited from hexamethyldisilazane (HMDSN) organic compounds via radio-frequency (RF) glow discharges. Afterwards the films were bombarded, from 15 to 60 min, with nitrogen ions using Plasma Immersion Ion Implantation (PIII) technique. X-ray photoelectron spectroscopy (XPS) showed that O-containing groups increased, while C-C and/or C-H groups decreased with treatment time. This result indicates chemical alterations of the polymeric films with the introduction of polar groups on the surface, which changes the surface wettability. In fact, the hydrophobic nature of a-SiCN:H films (contact angle of 100 degrees) was changed by nitrogen ion implantation and, and after aging in atmosphere air, all samples preserved the hydrophilic character (contact angle <80 degrees) independently of treatment time. The exposure of the films to oxygen plasma was performed to evaluate the etching rate, which dropped from 24% to 6% while the implantation time increased from 15 to 60 min. This data suggests that Pill increased the film structure strength, probably due to crosslinking enhancement of polymeric chains. Therefore, the treatment with nitrogen ions via Pill process was effective to modify the wettability and oxidation resistance of a-SiCN:H films. (C) 2014 Elsevier Ltd. All rights reserved.

Is it possible to encapsulate in a pill the benefits of an analytical treatment? Quickly suspending the symptoms? Since the nineteenth century psychiatry has offered to the so called mentally ill "medieval forms" of treatment, as is the case of institutional admissions, the straightjacket, lobotomies, shock treatments, etc. What has changed since the mid-twentieth century advent of chlorpromazine, the first psychoactive drug, and the "psychopharmacological revolution"? Today with the Psychiatric Reform mental institutions admissions are being gradually abandoned, yet we see the rise of psychoactive drugs as protagonists in mental health treatment. This theoretical essay is an extension of a master's thesis in progress on the long-term use of psychotropic drugs. It falls within the field of mental health, specifically in the debate on the medicalization of society in contemporary processes of subjectivation of the psychiatric clinics and the treatment modalities currently offered to individuals in their suffering-existence. Thus, we seek to problematize this degrading psychiatric clinics, which produces what we call the pill-subject.
