The sexual size dimorphism (SSD) is widespread among animals but proximate mechanisms of its ontogeny are still poorly understood even in important groups of vertebrates such as reptiles. Previous experiments in geckos showed that growth of both sexes slows substantially at their older age. Their SSD develops considerably a long time after sexual maturity, it is associated with earlier growth deceleration in the smaller sex and it is controlled by ovarian rather than testicular steroids. The aim of the thesis was to explore the previous knowledge by studying the ontogenesis of the sexually-dimorphic bone growth of the gecko Paroedura picta, the male- larger species with the most explored proximate mechanisms of SSD among geckos. I was most interested in the ontogeny of the growth plates activity and the epiphyseal ossification of the femur in both sexes and their relationship to age, body length, gonadal activity and levels of sex-specific steroids (estradiol and testosterone). The results show that P. picta has determinate growth and that epiphyseal ossification does not contribute to the SSD. The femoral growth plates close at the same age in both sexes; however, their closure occurs at smaller body length in females than in males. In the context of this and the previous studies, estradiol or other...

[pt] A utilização de barras de polímero reforçado com fibra contínua (Fiber reinforced polymer, ou FRP) como reforço no concreto armado vem ganhando relevância no mercado devido às suas propriedades não corrosivas, alta resistência, durabilidade e transparência eletromagnética. Por outro lado, o comportamento frágil e o baixo módulo de elasticidade das barras de FRP limita sua aplicação e difusão no mercado da construção civil. Sob esta perspectiva, este trabalho avalia, em uma primeira etapa, o incremento de ductilidade em vigas de concreto armado com barras de GFRP (Glass fiber reinforced polymer) por meio da adição de fibras dispersas de vidro AR (álcali resistente) à matriz cimentícia e/ou pelo confinamento do concreto nas regiões críticas com o uso de estribos de GFRP. Para tal, são reportados e discutidos os resultados de ensaios realizados em oito vigas isostáticas sob flexão de quatro pontos, sendo quatro superarmadas e quatro são subarmadas. Em geral, as estratégias adotadas se mostraram bem-sucedidas apenas para as vigas superarmadas, que passaram a apresentar falhas caracterizadas por formação de cunha de compressão e grandes deslocamentos até a ruptura. Para avaliação da ductilidade, foram adotados dois métodos distintos: um baseado em energia (índice de ductilidade, (micro)E) e outro baseado em deformação (fator de performance, (micro)M). Para as vigas subarmadas, o fator de performance por meio da curvatura e o fator de performance por meio da deflexão representaram maiores incrementos de ductilidade para a viga com adição de fibras dispersas devido ao efeito do enrijecimento à tração, enquanto o índice de ductilidade não se mostrou uma boa alternativa para estas vigas. Para as vigas superarmadas, o fator de performance por meio da curvatura e o índice de ductilidade representaram maiores incrementos de ductilidade para as vigas com confinamento, enquanto no fator de performance por meio da deflexão, o incremento de ductilidade foi mais significativo para as vigas com adição de fibras. Em uma segunda etapa, é avaliada a capacidade de redistribuição de momentos fletores em três vigas hiperestáticas de dois vãos reforçadas com barras de GFRP contendo maior taxa de armadura inferior, bem como configurações distintas de armadura transversal e uso de fibras. Foi possível observar um aumento do momento nos centros dos vãos de 30 por cento e uma redução no momento no apoio central superior a 60 por cento, quando comparados aos momentos elásticos, que confirmam a influência da configuração da armadura na distribuição de esforços. / [en] The use of continuous fiber reinforced polymer (FRP) bars as an internal reinforcement for concrete has gained attention due to its non-corrosive properties, high resistance, requiring electromagnetic transparency. On the other hand, the brittle behavior and low modulus of elasticity of FRP bars limit their application and diffusion in the civil construction market. From this perspective, this work evaluates, firstly, the increase of ductility in GFRP (glass-fiber reinforced polymer) reinforced concrete beams by adding dispersed alkali-resistant (AR) glass fibers to the cementitious matrix and/or by confinement of the concrete in critical regions with the use of GFRP stirrups. To accomplish this task, the results of tests performed on eight statically determinate beams under four-point bending are reported and discussed, four of which are under-reinforced and four are over-reinforced. In general, the strategies adopted were successful only for the overreinforced beams, whose failures were characterized by the formation of a compression wedge and large displacements before rupture. For ductility evaluation, two distinct methods were adopted: one based on energy (ductility index, (micro)E) and another based on deformation (performance factor, (micro)M). For under-reinforced beams, the performance factor through curvature and the performance factor through deflection led to greater ductility increments for the beam with the addition of dispersed fibers due to the tensile stiffening effect, while the ductility index did not lead to good results. For the over-reinforced beams, the performance factor through curvature and the ductility index were able to describe the greater ductility increments for the confined beams, while the performance factor through deflection resulted in a greater ductility increment for the beams with discrete fiber addition. In a second step, the capacity of redistribution of moments in three statically indeterminate GFRP reinforced concrete beams with two spans and with a higher lower reinforcement ratio was evaluated for two different configurations of transverse reinforcement and for the use of fibers. It was possible to observe an increase in the positive moment of 30 percent (center of span) and a reduction in the negative moment (central support) greater than 60 percent, when compared to the elastic moments, confirming the influence of the reinforcement configuration on the distribution of internal forces.

Shotcrete (sprayed concrete) was used for the first time in 1914 and has become of  growing importance in stabilizing the excavated tunnel sections over the past century.  Even though the technology develops, there are some difficult tasks such as the design of a bolt anchored tunnel lining made of shotcrete. A proven and established design method does not exist today; instead the design of tunnel linings are based on trial and error or experience from similar projects. One method used today, to determine the actual structural behavior of fiber reinforced shotcrete, is the standard beam test method. Previous studies have shown that the beam method gives scattered results since the testing volume are relatively small and the fibers might be unevenly distributed.  In 1998, an alternative to determine the actual structural behavior of reinforced shotcrete was proposed, based on using round determinate panels. In 2004 this method became a part of the American Society for Testing and Materials, ASTM, standards. The method has the potential of becoming a major, reliable test procedure that better reproduce the behavior of reinforced shotcrete in situ, compared to test beams. An experimental test series was performed to compare the different testing methods in terms of data variability and validity, in the laboratory of Vattenfall in Älvkarleby. The experiment was performed on 30 specimens in total, with five different concrete recipes. The difference in the recipe was the fiber and cement content. The round panels are designed according to ASTM C-1550 and the beams according to SS-EN14488-3. The results from the experiment is here presented and evaluated, and also including the data variability and validity for the proposed method. The two basic testing methods of using beams and round panels are investigated, compared and evaluated, and their advantages and disadvantages discussed. / Sprutbetong användes första gången år 1914 och har under det gångna århundradet blivit allt viktigare för att stabilisera utsprängda tunnelsektioner. Trots att tekniken utvecklas finns det svårigheter med att exempelvis utforma bultförankrade tunnelbeklädnader av sprutbetong. En beprövad och etablerad metod att konstruera sprutbetongbeklädnad existerar inte idag. Istället används erfarenhetsåterföring från tidigare projekt och/eller experimentella försök. En testmetod som används idag för att återskapa beteendet hos sprutbetong är balkförsök. Tidigare studier har däremot visat att resultaten från försöken oftast har stor spridning vilket kan bero på att brottytorna är små areor där fibrerna kan vara ojämnt fördelade vilket påverkar resultaten. År 1998 föreslogs en alternativ metod för att fastställa de mekaniska egenskaperna hos sprutbetong, baserat på användning av runda plattor. År 2004 blev denna metod en del av the American Society for Testing and Materials, ASTM, standarder. Metoden har potential att bli en viktigt och tillförlitligt testmetod som mer realistiskt efterliknar beteendet hos fiberarmerad sprutbetong jämfört med balkprovning. En experimentell försöksserie har genomförts hos Vattenfall i Älvkarleby, för att jämföra de två metoderna med avseende på mätosäkerhet. Försöksserien är på totalt 30 prover, där fem olika betongrecept använts. Cementmängden och fiberhalten varierade mellan de olika recepten. De runda plattorna är utförda enligt ASTM C-1550 och balkarna enligt SS-EN14488-3. Resultaten från försöken har redovisats och utvärderats, och en mätosäkerhersanalys presenteras för metoden ASTM C-1550. Korrelationen mellan resultaten från de två metoderna är beräknad och varianskoefficienten presenteras. För- och nackdelar mellan båda testmetoderna diskuteras.

The argument is developed by the reciprocity of two dialectic‟s criteria: the historic understanding of the libertarian aims and of its institutional actuality. The freedom as an ontological category, first criterion, and the political process of human liberation, the second, accomplish the elements of the reciprocity‟s dynamics as expounded in “Reason and Revolution” at 1941. The 1960‟s preface, “A note on dialectic” develops the reciprocity between the freedom‟s consciousness and the process of its actuality, as a alternative discourse instead of surrendering to the establishment. The text also recognizes in the Marcuse‟s work of 1966, the analogy between the essential criteria of the dialectic perspective and the understanding that the affluent capitalism‟s negation demands two types of strategies, one stood by the concept of negation one as a internal power and the other as an external one. The internal negation reveals the unaccepetable contradictions of the capitalist system and the external permits understanding the protest for justice and for the human good, universal values, beyond the capitalist system. / “„Raison et Révolution' pour une dialectique de changement institutionel" déploit une fondement philosophique pour la practique révolutionnaire. L'argumentation était déployée par la réciprocité entre deux critères de la dialectique: la compréhension historique des objetives libertaires et la compréhension de sa éféctivité institutionel. La liberté comme catégorie ontologique, prémier critère et le processus politique de libération humaine, le second, constituent les éléments de la dynamique de la réciprocité exposés dans l'oeuvre de 1941, "Raison et Révolution". La réciprocité entre le procesus de connaissance de la libération et le processus de sa éféctivité est confirmée au préface."A note on dialectic" tant comme une language alternative à la capitulation à l'établissement comme le déploiement de l'argumentation à l'année de 1960. Le texte de 1966 "Le concept de négation dans la dialectique" on fait reconnaître l'analogie entre les critères essentiels pour une perspective dialectique et la compréhension que la négation du capitalisme développé demande deux types de stratégies, une fondée sur la négation comme supération interne et l'autre fondée sur la négation extérieure, la première révélée par les contradictions internes d'une totalité-part, la seconde, supération extérieure, que permet de comprendre la clameur de la justice e du bien, éléments universels de la totalité-majeure que la totalité-part capitaliste. / “Razão e Revolução de Herbert Marcuse, por uma Dialética de Alteração Institucional”, expõe a fundamentação filosófica de uma práxis revolucionária. A argumentação é desenvolvida a partir da reciprocidade entre dois critérios da dialética: a compreensão histórica dos objetivos libertários e a compreensão de sua efetivação institucional. A liberdade como categoria ontológica, primeiro critério e o processo político de libertação humana, o segundo, constituem-se elementos da dinâmica de reciprocidade como expostos na obra de 1941, “Razão e Revolução”. No prefácio “A note on dialectic” de 1960, a reciprocidade entre o processo de conscientização da liberdade e o processo de sua efetivação, constitue-se num discurso alternativo à capitulação ao estabelecido. Em 1966, reconhecemos a analogia dos critérios essenciais de uma perspectiva dialética com a compreensão de que a negação do capitalismo tardio exige dois tipos de estratégias, uma fundada na negação enquanto superação interna, e a outra fundada na negação como superação externa, a primeira expressa a partir das contradições internas de um todo-parte e a segunda, a superação externa, permite compreender o clamor por justiça e pelo bem, elementos universais de uma totalidade maior do que o todo-parte capitalista.

The transformation of the Department of Correctional Services into an institution of rehabilitation and the promotion of corrections as a societal responsibility brought a new dimension to the release policy of South Africa. A new Correctional Services Act 111 of 1998 came into effect and the Department of Correctional Services published a White Paper on Corrections during 2005. The idealistic correctional goal of protecting the community while rehabilitating the offender has served as a reason for conducting research into the parole process from a South African perspective. The qualitative aim of the study is to explore parole as a phenomenon and to describe the process involved in successfully reintegrating an offender into the community. The significant role that Correctional Supervision and Parole Boards play in the parole process and the emphasis they place on community safety, the interest of the victim and the rehabilitation and control of offenders as part of their mission statement are highlighted in the study. / Penology / M.A. (Penology)
