Ma pompe, ma vie: revue de la littérature

Le diabète de type 1 est une maladie chronique dont le traitement est important pour éviter des complications aiguës et chroniques. L’adolescence est une période de passage entre l’état d’enfant et celui d’adulte caractérisée par des chamboulements importants. Lorsqu’un jeune doit traverser l’adolescence avec le diabète, les contraintes de la maladie chronique viennent se rajouter aux difficultés relatives à cette période de la vie. Cette complexité se répercute sur la prise en soins de l’équipe pluridisciplinaire et la question suivante se pose : comment les infirmières spécialisées en diabétologie peuvent-elles aider les adolescents, durant ce passage complexe, à maintenir une bonne observance thérapeutique

Electrophilic fluorination methodology

Chapter One This chapter reviews the historical background of the fluorination using both elemental fluorine and N-F reagents. It relates the properties and preparations of these electrophilic reagents. And finally it discusses the use of these reagents in selective electrophilic fluorination (formation of C-F bond from C-H bond) of organic compounds. Chapter Two, Three and Four These chapters present our investigations into the fluorination of hydrocarbon systems containing an electron withdrawing group (ewg).Chapter Two shows the difference in reactivity of elemental fluorine and Selectfluor(^TM) towards aldehydes and ketones. Select fluor gives rise to a-fluorinated compound when reacting with ketones (acyclic and cyclic ones) whereas different results were observed using fluorine. In Chapter Three aldehydes are submitted to fluorination which occurred at the carbonyl and not on the chain. Finally, Chapter Four review the fluorination of nitriles using both fluorinating reagents. Chapter Five In this last Chapter we explore the fluorination of cyclic ethers (hydrocarbon systems containing an electron donating group) using both elemental fluorine and Selectfluor(^TM). Unexpected derivatives were identified. Chanter Six to Nine Experimental details relating to Chapter Two-Five

Análise da relação entre estresse e o desempenho escolar dos adolescentes do ensino médio do Colégio Militar de Brasília

Dissertação (mestrado)—Universidade de Brasília, Faculdade de Ciências da Saúde, Programa de Pós-Graduação em Ciências da Saúde, 2013.O estresse é caracterizado por um conjunto de reações do organismo diante que alguma situação que lhe exija uma adaptação. Quando é excessivo, o estresse pode comprometer o desenvolvimento cognitivo, afetivo, social e emocional, principalmente quando atinge os adolescentes, que muitas vezes não têm maturidade e capacidade para administrar situações estressantes. Devido às exigências serem maiores do que suas capacidades, podem reagir negativamente e apresentar um conjunto de sintomas como cansaço mental, dificuldade de concentração,perda de memória imediata, que interferem sobretudo no seu desempenho escolar. Neste trabalho objetiva-se analisar a relação existente entre estresse e o desempenho escolar de adolescentes do Ensino Médio do Colégio Militar de Brasília. Para tal, foi efetuado um estudo de exploratório, descritivo de natureza quantitativa. Participaram desse estudo 82 alunos pertencentes aos 1º, 2º e 3º anos do Ensino Médio. Para coleta de dados, foram utilizados os seguintes instrumentos: Escala de Stress para adolescentes (ESA), Inventário de Eventos Estressores na Adolescência (IEEA) e um questionário baseado na literatura. Os resultados demonstram que da amostra investigada apenas 28 estudantes apresentaram estresse. Houve predominância das fases de alerta e exaustão, e dos sintomas psicológicos. Os eventos estressores que foram mais frequentes na amostra total se referiam aos domínios familiar, social e escolar. Relações estabelecidas nesses contextos influenciam significativamente o comportamento dos adolescentes. Esse resultado demonstra que os fatores ambientais funcionam tanto como fatores de proteção, quanto de risco à saúde dos adolescentes. A média escolar atingiu percentual menor entre os estudantes estressados, fato que permite inferir que o estresse de alguma forma afeta o desempenho de escolar dos estudantes. ______________________________________________________________________________________ ABSTRACTStress is characterized by a set of reactions of the organism on which any situation that requires an adaptation. When is excessive stress can impair cognitive development, social, affective and emotional, especially when reaches the teens, who often have no maturity and ability to handle stressful situations. Due to the requirements are greater than their difficulty concentrating, short-term memory loss, which interfere in their school performance. This study aims to analyze the relationship between stress and the school performance of high school teens of military school of Brasilia. To this end, was carried out an exploratory study, of the quantitative nature. The following instruments were used: Stress Scale for Adolescents (ESA), Inventory of Stressors Events in Adolescence (IEEA) and a questionnaire based on literature. The results show that the sample investigated only 28 students showed stress. There was a predominance of the stages of alert and exhaustion, and psychological symptoms. The stressors that events were more frequent in the total sample referred to family, social and school areas. Relations established in these contexts influence significantly the behavior of adolescents. This result demonstrates that environmental factors work both as protective factors, how much risk to health of adolescents. The average hit smaller percentage among school students stressed, fact allows inferring that somehow stress affects school performance of the students

As marcas de uso regionais em dicionários bilíngues escolares português/espanhol

IX Congresso Brasileiro de Hispanistas realizado nos dias 22 a 25 agosto 2016As marcas de uso diatópicas indicam restrições do tipo geográfico para o uso de uma determinada unidade lexical. No caso específico da língua espanhola, a confecção de dicionários bilíngues parece não dar real relevância à variação linguística. Considerando a falta de reflexão mais profunda sobre a diversidade linguística do espanhol, no âmbito da lexicografia, este trabalho discute a necessidade de normalização de marcas de uso dialetais em dicionário bilíngues e descreve como tais marcas estão inseridas em dicionários bilíngues escolares do espanhol. As análises, ainda em andamento, nos permitem entender que algumas marcas de uso se apresentam, nos dicionários analisados, de forma ambígua e incoerente, tanto no que se refere à sustentação quanto à pertinência da classificação adotada pelo lexicógrafo. Concluímos, portanto, que esta imprecisão dos dados se deu, em parte, devido à falta de uma explicitação de proposta lexicográfica quanto ao tratamento da variação linguística no espanhol nos verbetes das obras consultadasUNILA­-UNIOEST

A constant phase approach for the frequency response of stochastic linear oscillators

International audienceWhen studying a mechanical structure, evaluation of its frequency response function (FRF) over a given frequency range is one of the main interests. Computational cost aside, evaluating FRFs presents no methodological difficulty in the deterministic case. Doing this when the model includes some uncertain parameters may however be more difficult as multimodality can arise around resonances. Indeed, even for a single degree of freedom system, it can be shown that usual methods of the probabilistic frame such as generalized Polynomial Chaos may fail to properly describe the probability density function of the response amplitude. This study proposes another approach which involves a shift in the usual quantities used to draw FRFs. Instead of computing the stochastic response for a given excitation frequency, this work adopts a constant response phase point of view. For each phase value of the oscillator response, the uncertainty over some parameters is propagated to the corresponding uncertain amplitudes and excitation frequencies. This provides much smoother variations of the involved quantities which are much easier to describe using a simple Polynomial Chaos approach. This also provides a mean to conduct a straightforward stochastic study of special points such as the maximum of amplitude (which matches a given phase) or the point for which the response is in quadrature with the excitation. Both analytical and numerical results will be exposed for a single degree of freedom oscillator whose squared eigen frequency (or stiffness) follows a uniform law

Surveillance acoustique des cavités à risque de fontis et d'effondrements localisés

National audienceIt is very difficult to monitor sinkholes and local collapses from underground using the classical geotechnical instrumentation since the location of such pre-existing phenomena cannot be easily approached or forecast in time in wide and complex underground cavities. INERIS developed and tested an acoustic method to detect, localize and characterize rock falls with the help of a few sensors.Les cavités souterraines de faible profondeur, naturelles ou anthropiques, peuvent être à l'origine de risques de mouvements de terrains par fontis ou par effondrement localisé. Ce phénomène touche l'ensemble du territoire national. Dans l'attente d'un traitement, une surveillance peut permettre de gérer le risque. Jusqu'à présent, cette surveillance était essentiellement réalisée par inspection visuelle et par instrumentation géotechnique conventionnelle. Cette démarche présentant plusieurs limites dans le suivi des phénomènes dans la continuité et d'exposition des équipes intervenantes, il était important d'examiner de nouvelles solutions instrumentales

Structure of smectic defect cores: an X-ray study of 8CB liquid crystal ultra-thin films

We study the structure of very thin liquid crystal films frustrated by antagonistic anchorings in the smectic phase. In a cylindrical geometry, the structure is dominated by the defects for film thicknesses smaller than 150 nm and the detailed topology of the defects cores can be revealed by x-ray diffraction. They appear to be split in half tube-shaped Rotating Grain Boundaries (RGB). We determine the RGB spatial extension and evaluate its energy per unit line. Both are significantly larger than the ones usually proposed in the literatureComment: 4 page

Melun – 10 rue de Dammarie

Une campagne d’évaluation archéologique a été réalisée du 4 au 17 août 1998 au no 10 de la rue de Dammarie, préventivement à la construction d’une église. Cette rue est située sur la rive sud de la Seine, dans la plaine de la Varenne ; le no 10 n’est qu’à environ 300 m du fleuve. La partie orientale (200 m2) a déjà fait l’objet d’une campagne d’investigation en 1995 à la faveur d’un premier projet immobilier. Les principaux vestiges mis au jour sont : des lambeaux de sols en argile ; des dépo..

Effectiveness of organizational mission of the public security secretaries of the Brazilian States

The organizational mission is an important tool to support the management of an organization. This article aims to analyze the elaboration of the organizational missions of the Secretariats of Public Security (SSPs) of the Brazilian states, based on the elements proposed by Pearce (1982) and Pearce and David (1987). For this, the data were treated quantitatively, and soon after an analysis was made on the effectiveness of the construction of the missions, based on the criteria established by the cited authors. As a result, the elements "Product or service offered" and "Audience" were found more frequently. In the comparative analysis of the SSP mission by region of the country, two points stand out: first, the South region is the one that the missions present more elements indicated in the literature; second that the state that presented more elements was "Maranhão" located in the Northeast region
