In a broad sense, this investment is directed to one s own descendant, but in some cases, such as in adoption, resources are directed to non-relatives even in the absence of fitness benefits. Once there are many factors involved in adoption, this study investigated adopters candidates, aiming to analyze aspects considered by them for adopting, based on the Evolutionary Psychology s perspective. We analyzed the judicial proceedings? files people who had been inlisted for adoption at the 2? Childhood and Adolescence Law Court, Natal-RN. The adopter s motivations were classified into biological or social reasons. A relationship between adopters? age and kind of motivation was found: requirements of young people were related to biological reasons while requirements of the old ones were related to social reasons. Fertility, mainly female requirer?s fertility, underlie this relationship, considering that women fertility is strongly influenced by age. The reasons to adopt were also related to the age of the desired child, once that people who wanted children older than 25 months alleged social reasons while those that wanted younger babies alleged biological reasons. There are lots of motives to adopt a child, but the phenomenon of adoption is broadly acknowledged by society as an act of love and the adoptive parents are often regarded as kind and generous people. It was observed, instead, that the reasons to adopt comes from the adopters themselves, related to the fulfillment of personal needs, such as increasing the family, carrying out mother/father role or having a company or someone to care form them in elderly age / O investimento que os pais direcionam ? prole aumenta a sua taxa de sobreviv?ncia ao mesmo tempo em que diminui as chances dos pais de investir em futuras proles. Em geral, o investimento ? direcionado ? pr?pria descend?ncia do indiv?duo, mas percebe-se que existe investimento parental mesmo quando n?o h? ganhos em termos de aptid?o, como por exemplo na ado??o, em que recursos s?o dirigidos a n?o aparentados. Considerando que a ado??o envolve v?rios fatores, foi nosso objetivo realizar um estudo com um enfoque nos futuros pais adotivos, buscando investigar os par?metros considerados para ado??o, utilizando como base te?rica a Psicologia Evolucionista. Para isto, analisou-se o arquivo de pessoas cadastradas para ado??o na 2? vara da Inf?ncia e Juventude da Comarca de Natal (RN). As motiva??es dos requerentes ? ado??o puderam ser classificadas em dois grandes grupos: biol?gicas e sociais. Encontrou-se uma rela??o entre o tipo de motiva??o e a idade dos requerentes, sendo o motivo biol?gico relacionado a faixas et?rias mais jovens dos requerentes e o social a faixas et?rias mais velhas. Um dos fatores que permearam esta rela??o foi a fertilidade, sobretudo das requerentes, uma vez que a fertilidade feminina ? fortemente influenciada pela idade. Tamb?m encontrou-se uma rela??o entre o tipo de motivo e a faixa et?ria da crian?a pretendida, em que pessoas que queriam adotar crian?as com mais de 25 meses apresentavam motivos sociais e as que queriam crian?as de 0 a 24 meses apresentavam motivos biol?gicos. As raz?es para adotar foram v?rias, mas esse fen?meno ? enfatizado na sociedade como um ato de amor, e costumeiramente o adotante visto como uma pessoa solid?ria e bondosa. Observou-se, no entanto, que as motiva??es para adotar partem da pr?pria pessoa, considerando a satisfa??o de necessidades pessoais, como exercer o papel materno, paterno ou ambos, ampliar a fam?lia ou ter uma companhia ou algu?m de quem receba cuidados na velhice

In this work, an analytical approach is used along with nodal schemes for the solution of xed source two-dimensional neutron transport problems, in Cartesian geometry, de ned in heterogeneous medium, with anisotropic scattering. The methodology is developed from the discrete ordinates version of the two-dimensional transport equation along with the level symmetric angular quadrature set. One-dimensional equations for the averaged angular uxes are obtained by transverse integration of the original problem. Such equations are solved by the ADO method. Explicit expressions in spatial variables are derived for averaged uxes in each region in which the domain is subdivided. The solution in each region is coupled with that of its neighbouring regions to provide the solution in the whole domain, without resorting to using iterative methods. As usual in nodal schemes, auxiliary equations are needed. Here two di erent treatments were given to this issue: one based on relations between the unknown ows in the contours of the regions and the average angular uxes, and another in which these ows are approximated by polynomials of order zero being in this case, incorporated into the source term. Numerical results were compared with available literature showing the solution preserve the computational e ciency which has been a good feature of the ADO method when applied to different problems. / Neste trabalho, uma abordagem analítica é utilizada juntamente com esquemas nodais na resolução de problemas bidimensionais de transporte de nêutrons de fonte fixa, em geometria cartesiana, definidos em meio heterogêneo, com espalhamento anisotrópico. A metodologia proposta é desenvolvida a partir da versão em ordenadas discretas da equação de transporte bidimensional, juntamente com o esquema de quadratura simétrica de nível. As equações em ordenadas discretas são integradas transversalmente, originando equações unidimensionais para os fluxos angulares médios. Tais equações unidimensionais são resolvidas pelo método ADO (Analytical Discrete Ordinates). Expressões explícitas nas variáveis espaciais são derivadas para os fluxos angulares médios em cada região em que o domínio foi subdividido. A solução em cada região é acoplada às regiões vizinhas, para fornecer a solução no domínio todo, sem a utilização de métodos iterativos. Como usual em esquemas nodais, equações auxiliares são necessárias, recebendo neste estudo dois tratamentos distintos: um em que os fluxos desconhecidos nos contornos das regiões assumem relações de proporcionalidade, com os fluxos angulares médios; e, outro, em que esses fluxos são aproximados por polinômios de ordem zero sendo, nesse caso, incorporados ao termo fonte. Resultados numéricos obtidos e comparados com disponíveis na literatura mostram a viabilidade da formulação, mantendo a eficiência computacional já verificada no tratamento de outros problemas, com o uso do método ADO.

Cette réflexion aborde la protection de l’enfance sous un autre angle que celui présenté par les pouvoirs publics. Sa singularité repose sur sa manière de montrer la mise en place progressive des mécanismes de protection de l’enfance. Elle décrit les rapports qu’entretiennent la famille et les pouvoirs publics : État, collectivités locales ; soulève les raisons réelles de leur l’intervention en décrivent les mécanismes ayant entraîné l’assentiment de la famille au projet de vie collective représenté par l’éducation et l’accession des enfants à l’autonomie. Si cette implication peut être salutaire, elle entraine aussi une fragilisation des parents déjà affaiblis par des difficultés sociale et professionnelle. Cette thèse explore certains aspects non évoqués qui constituent pourtant un danger pour les enfants. Elle s’appuie sur deux éléments : il s’agit des données sur l’enfance en danger recueillies par l’Antenne enfance ado et des dispositifs de prise en charge élaborée par le Conseil général du Doubs. Les manquements observés supposent une refonte de la protection de l’enfance dans la manière de considérer la famille. / This reflection approaches the child welfare under another angle than that presented by public authorities. Its peculiarity bases on the way it shows the progressive implementation of the mechanisms of child welfare. It describes the connections that maintain the family and the public authorities: state, local authorities; raise the real reasons of them the intervention describe mechanisms having pulled the approval of the family in the plan of collective life represented by the education and the entry of the children in the autonomy. If this implication can be wholesome, it also entraine an embrittlement of the parents already weakened by social and professional difficulties. This thesis investigates certain not evoked aspects which constitute nevertheless a danger for the children.It leans on two elements: it is about data on the childhood in danger collected by the Office childhood teenager and devices of care elaborated by the General Council of the Doubs. The observed breaches suppose a revision of the child welfare in the way of considering the family.

Pesquisa do Estado de S?o Paulo - FAPESP / The prediction of the reinforced concrete beams behavior under bending is essential to design these elements. Usually the models do not incorporate the concrete stress contribution, which may underestimate the structural element strain that use steel fiber reinforced concrete (SFRC) under permanent or temporary loads. This work presents a variational formulation based on the finite difference energy method (EFDM) in predicting the flexural behavior of concrete beams reinforced, that uses SFRC. The proposed model uses the classical lamination theory (CLT) with a damage model (Mazars, 1984) applied to the SFRC. The reinforcement was considered as a layer of a perfect elastic-plastic material. Comparing the load-displacement numerical results with those of the literature to reinforced concrete beams demonstrates the consistency of the proposed model. / A previs?o do comportamento de vigas de concreto armado sob flex?o ? fundamental para o adequado dimensionamento destes elementos. Usualmente, os modelos n?o incorporam a contribui??o do concreto tracionado, o que pode subestimar as deforma??es no elemento estrutural que utilizem o concreto refor?ado com fibras (CRFA) sob cargas de curta e longa dura??o. No presente trabalho ? apresentada uma formula??o variacional com base no m?todo das diferen?as finitas energ?ticas (MDFE) para a previs?o do comportamento ? flex?o de vigas de concreto simples ou armado refor?adas com fibras de a?o. O modelo proposto combina a teoria cl?ssica de laminados (TCL) com um modelo de dano (Mazars, 1984) aplicado ao concreto. O refor?o (armadura longitudinal) foi considerado como uma l?mina de um material elasto-pl?stico perfeito. A compara??o dos resultados num?ricos com resultados encontrados na literatura para vigas de concreto armado, em termos de cargadeslocamento, demonstra a coer?ncia do modelo proposto.

This dissertation explores the relevance of recent studies of Aristotle’s comic theory to the central dramatists of early modern England, Ben Jonson and William Shakespeare. Applications of the Poetics to Renaissance English drama tend to treat Aristotle’s theory historically, as a set of concepts mediated to England by continental redactions. But these often conflated the Poetics’ focus on literary form with the Renaissance’s predominant interest in literature’s rhetorical effect, reducing Aristotle’s genuinely speculative theory to a series of often pedantic literary prescriptions. Recent scholarship has both undone these misinterpretations and developed the comic theory latent in the Poetics. Ironically, these studies make Jonson’s and Shakespeare’s comedy look much more Aristotelian than do Renaissance ones. So rather than taking the Poetics simply as a possible source for each dramatist, I read it primarily as a literary theory that, when reinvigorated by modern scholarship, can explain structures and effects arrived at practically by these dramatists. Three recent hypotheses are especially pertinent to Jonson and Shakespeare: that comic hoaxes aim to expose comic error, which is for Aristotle a deviation from the mean of virtue; that “righteous indignation” is the comic emotion equivalent to the “pity and fear” of tragedy; and that catharsis is a clarification, rather than purgation, of reason and emotion. In light of these, I offer detailed readings of four plays that demonstrate these authors’ comic range: from Jonson’s satirical Every Man Out of His Humour to the almost farcical Epicoene, and from Shakespeare’s romantic Much Ado About Nothing to the tragicomic Measure for Measure. These plays demonstrate a variety of ways in which catharsis, the end of drama, results directly from the comic hoax and involves both the audience’s and characters’ experience of indignation and their comprehension of its relationship to the emotions of envy and pity. In each case, Aristotle’s incisive but flexible theoretical framework enables an explanation of the emotional pain present in the these “comedies of affliction” and reveals remarkable similarities between dramatists usually described as direct opposites.

In that sense, the lignocellulosic waste is used for manufacture of homogeneous wood sheet agglomerate (LHWS) and lignocellulosic load which take part of a polymeric composite with fiber glass E (GFRP-WC). In the manufacturing of the homogeneous wood sheet agglomerate (LHWS), it was used mamona?s resin as waste s agglutinating element. The plates were taken up in a hydraulic press engine, heated, with temperature control, where they were manufactured for different percentage of waste wood and coconuts nuc?fera linn. Physical tests were conducted to determine the absorption of water, density, damp grade (in two hours and twenty-four hours), swelling thickness (in two hours and twenty-four hours), and mechanical tests to evaluate the parallel tensile strength (internal stick) and bending and the static (steady) flexural. The physical test?s results indicate that the LHWS can be classified as bonded wood plate of high-density and with highly water resistant. In the mechanical tests it was possible to establish that LHWS presents different characteristics when submitted to uniaxial tensile and to the static (steady) flexural, since brittle and elasticity module had a variation according to the amount of dry endocarp used to manufacture each trace of LHWS. The GFRP-WC was industrially manufactured by a hand-lay-up process where the fiber glass E was used as reinforcement the lignocellul?sic?s waste as load. The matrix was made with ortofitalic unsaturated polyester resin. Physical and mechanical tests were performed in presence of saturated humidity and dry. The results indicated good performance of the GFRP-WC, as traction as in flexion in three points. The presence of water influenced the modules obtained in the flexural and tensile but there were no significant alteration in the properties analyzed. As for the fracture, the analysis showed that the effects are more harmful in the presence of damp, under the action of loading tested, but despite this, the fracture was well defined starting in the external parts and spreading to the internal regions when one when it reaches the hybrid load / Na presente pesquisam-se a utiliza??o do endocarpo do cocos nuc?fera linn e o res?duo de derivados de madeira e de m?veis como mat?ria-prima para uso tecnol?gico. Nesse sentido, usam-se esses res?duos lignocelul?sico na fabrica??o de chapa de madeira aglomerada homog?nea (CHMC) e, como carga, em comp?sito polim?rico refor?ado com fibra de vidro E (PHFV-MC). Na fabrica??o da chapa de madeira aglomerada homog?nea (CHMC) usou-se a resina ? base de mamona como elemento aglutinante dos res?duos. As chapas foram conformadas em uma prensa hidr?ulica aquecida com controle de temperatura, onde as mesmas foram fabricadas para diferentes percentuais dos res?duos de madeira e do cocos nuc?fera linn. Foram realizados ensaios f?sicos para a determina??o de absor??o de ?gua, densidade, do teor de umidade (em duas horas e vinte e quatro horas), inchamento de espessura (em duas horas e vinte e quatro horas), e ensaios mec?nicos para a determina??o da resist?ncia ? tra??o paralela (ades?o interna) e o ensaio de flex?o est?tica. Os resultados obtidos nos ensaios f?sicos indicam que a CHMC pode ser classificada como chapa de madeira aglomerada de alta densidade e que suporta bem a presen?a de ?gua. Nos ensaios mec?nicos foi poss?vel constatar que a CHMC apresenta caracter?sticas distintas quando submetida ? for?a de tra??o uniaxial e ? flex?o est?tica, uma vez que os m?dulos de ruptura e de elasticidade variaram em fun??o da quantidade do endocarpo seco usado para fabricar cada tra?o da CHMC. A PHFV-MC foi fabricada industrialmente por meio do processo hand-lay-up onde a fibra de vidro-E foi usada como refor?o e os res?duos lignocelul?sicos, como carga. A matriz foi ? base de resina poli?ster ortofit?lica insaturada. Foram realizados ensaios f?sicos e mec?nicos em presen?a de umidade saturada e a seco. Os resultados indicaram um bom desempenho da PHFV-MC, tanto na tra??o quanto na flex?o em tr?s pontos. A presen?a de ?gua influenciou os m?dulos obtidos na flex?o e na tra??o, mas n?o alterou significativamente as propriedades analisadas. Quanto ? fratura, a an?lise mostrou que os efeitos s?o mais danosos em presen?a da umidade, sob a a??o dos carregamentos analisados, mas, apesar disto, a fratura se mostrou bastante caracterizada, iniciando nas regi?es externas e se propagando para as regi?es internas quando atinge a carga h?brida

The objective of this research work is to study the challenges in designing these fabrics bring these materials as to its mechanical characterization and fracture mechanisms involved. Some parameters associated with the process and / or form of hybridization stand out as influential factors in the final performance of the material such as the presence of anisotropy, so the fabric weave, the process of making the same, normative geometry of the specimens, among others. This sense, four laminates were developed based hybrid reinforcement fabrics involving AS4 carbon fiber, kevlar and glass 49-E as the matrix epoxy vinyl ester resin (DERAKANE 411-350). All laminates were formed each with four layers of reinforcements. Depending on the hybrid fabric, all the influencing factors mentioned above have been studied for laminates. All laminates were manufactured industrially used being the lamination process manual (hand-lay-up). All mechanical characterization and study of the mechanism of fracture (fracture mechanics) was developed for laminates subjected to uniaxial tensile test, bending in three and uniaxial compression.
