Full textThe titi monkeys, genus Callicebus Thomas, 1903 are primates that occur throughout the Amazon and Orinoco basins, in the Atlantic forest region and in parts of Caatinga, Chaco and Pantanal. There are 33 species of this genus divided into five groups: Moloch, Cupreus, Torquatus, Donacophilus, and Personatus. The Moloch group is composed of Amazon species, distributed between the left bank of Rio Madeira and right bank of the Tocantins-Araguaia rivers. The taxonomic history of the titi monkeys from the Moloch group revealed some nomenclatural problems, so that the species and subspecies category varied frequently. Therefore, the aim of the present study was to present a taxonomic revision of the Callicebus species from the Moloch group, describing and/or redescribing its taxa, and to clarify the number of nominal taxa within it. I perform qualitative and quantitative analysis using specimens deposited in zoological collections. The qualitative characters related to the color pattern were mapped, aiming to find geographical gaps or clines. The quantitative characters consisted of cranial and dental morphometry that were submitted to statistical tests of sexual dimorphism, ontogenetic and geographical variation. For these, I performed univariate and multivariate analysis. The results showed that, for the Moloch group species, the color pattern is the main diagnostic characteristic, not showing significant differences in the cranial and dental morphology and morphometry. Therefore, seven species of the genus Callicebus, Moloch group, are here considered taxonomically valid: C. moloch, C. cinerascens, C. hoffmannsi, C. baptista, C. brunneus, C. vieirai, C. miltoni, and the new synonymy of C. bernhardi with C. moloch.

Full textAs atividades humanas têm mudado drasticamente a cobertura natural de nosso planeta. Mundialmente, a destruição de ecossistemas e o desenvolvimento industrial desenfreado provocam graves problemas ambientais, que vão desde a perda de biodiversidade até eventuais mudanças climáticas globais. O mapeamento da cobertura vegetal é um insumo científico essencial para avaliar a evolução da paisagem no tempo e no espaço. Neste trabalho, utilizamos a análise multitemporal, o qual teve caráter inédito para os biomas da região, a Mata Atlântica e a Caatinga, na verificação do histórico de desmatamento da região. Estas técnicas foram utilizadas para avaliar os efeitos do processo de desmatamento sobre as populações remanescentes de duas espécies ameaçadas, os macacos guigós, Callicebus coimbrai Kobayashi & Langguth (1999), que habita a Mata Atlântica e está classificada como ameaçada de extinção na categoria em perigo pela IUCN e Callicebus barbarabrownae Hershkovitz (1990) que habita a Caatinga e está classificada atualmente como criticamente em perigo de extinção. O objetivo foi realizar uma análise multitemporal do processo de desmatamento (1980-2000) da área de estudo e diagnosticar seus efeitos sobre as populações de Callicebus. A área de estudo (8º27 56 -12º3 35 de latitude Sul e 36º14 43 -40º59 4 de longitude Oeste) compreende o estado de Sergipe e parte da região do extremo norte do estado da Bahia atingindo uma área de aproximadamente 80.000 km2. O pré-processamento compreendeu a coleta e registro das imagens e trabalho de campo. A análise multitemporal incluiu operações aritméticas (IV Índice de Vegetação e ACP Análise por Componentes Principais), interpretação visual, classificação supervisada através do classificador de distância euclidiana, pós-classificação, edição e mosaico das cenas classificadas. Oito classes foram mapeadas: Caatinga arbórea, Caatinga arbórea-arbustiva, Caatinga arbustiva, Mata Atlântica, Pasto, Área Urbana, Hidrografia e Nuvens. A análise do desmatamento levou em conta o bioma, o tipo de vegetação, a fragmentação, a distribuição desta fragmentação, a redução ou aumento dos fragmentos de vegetação e o tipo de registro de Callicebus. O registro das 25 cenas atingiram erros menores que meio pixel (menor que 15 metros) variando de 0,403 a 0,498 pixels. Foram coletados 750 pontos nos trabalhos de campo, através do receptor GPS e aproximadamente 8000 fotos. Foram identificadas grandes áreas de Caatinga arbórea-arbustiva que se mativeram nas três décadas, enquanto que a Mata Atlântica foi caracterizada por extenso desmatamento e o aumento das áreas de pasto. Foram coletados 279 registros de presença/ausência do macaco guigó divididos nas categorias: registro de presença, relatos não confirmados, extinções locais e áreas vistoriadas sem registro. Diversos cenários foram analisados para dois modelos teóricos criados, o de fragmentação (a) e de redução de núcleo (b). O modelo (a) apresenta cenários que indicam a maior probabilidade de extinção do macaco guigó, devido ao tamanho reduzido dos fragmentos, isolamento e a falta de conectividade, enquanto o modelo (b) apresenta cenários mais favoráveis para conservação com grandes fragmentos e melhor conectividade. A área de transição entre a distribuição das duas espécies,onde o género parece estar ausente, também foi investigad. Os dados fornecem uma série de insights sobre o estado de conservação das espécies e seus requisitos ecológicos, bem como diretrizes para a tomada de decisões sobre as estratégias de manejo para a conservação destas espécies e os fragmentos florestais que elas habitam.

Full textThis thesis deals with the literary and epistemological problems raised by the historical portrait in the work of Livy. The first section studies all the stylistic and rhetorical figures and methods that constitute an historical portrait: narration, dramatic portrayal, speeches. The technique of Livy produces a consistent kind of portrait, in which the didactic and persuasive aim of his work is reflected. The second section proposes a typological classification of the 2000 people in his Ab Urbe condita, according to three main categories: family, social role, ethnic group. The moral and political ideology that lies behind the characterization of all these people, whether barbarian or roman, is readily understandable. Livy's wishes to create a unique portrait, that of the romans, populus princeps, united around national values which are those of the republic. The final section of this thesis demonstrates how Livy has succeeded in going beyond the common traits of the portraits and that of his own idealistic vision of the romans, and has given us a description of the historical uniqueness of these people and of the true evolution of Rome. In particular, it can be seem that the description of the protagonists vacillates between a collective notion of heroism, according to the mos maicrum, and a Hellenistic concept, which centers more on the individual. The esthetic value of these portraits, which at the same time are both tragic and sublime, is founded on a delicate balance between truth and verisimilitude, and between history and poetry. This makes it possible to reduce the antagonism between the common traits and that is

Full textThis master thesis is about Niccolò Machiavelli's Discourses on Livy. Our main issue is to know why did Machiavelli interest in Livy's History of Rome, from which point of view did he read and comment on it, and the political lessons he taught Florence from it. In chapter one, we present our method inspired from the Cambridge contextualist school. Next, we put Machiavelli back in his time through a short biography; then we present Livy's History of Rome, and the author himself. In chapter two, we present the Discourses on Livy and the background in which Machiavellli wrote it. We demonstrate how this work follows on from the Renaissance litterature and at the same time breaks with it. Then we study the possible connections between the ancient Rome and the 16th century Florence. Afterwards, we comment some chapters of the Discourses, as an exemple. The last chapter deals with the philosophical issues in the Discourses: which view on History reveals through it, which part do play the concepts of virtù and fortuna and finally, the possibility of updating Machiavelli's approach, that is to say taking - or not - into account the historical exemples as a guide for today's political action.

Full textTitoist Yugoslavia—the multiethnic state rising out of the chaos of World War II—is a particularly interesting setting to examine the integrity of the modern nation-state and, more specifically, the viability of a distinctly multi-ethnic nation-building project. Much scholarly literature has been devoted to the brutal civil wars that destroyed Yugoslavia during the 1990s with emphasizes on divisive nationalism and dysfunctional politics. But what held Tito’s state together for the preceding forty-six years? In an attempt to understand better what united the stable, multiethnic, and successful Yugoslavia that existed before 1991, this dissertation illuminates the pervasive problem of legitimacy within this larger history. Cast aside and threatened with removal by Stalin’s henchmen after the war, Tito made his revolution a genuine alternative to Soviet control. Because Tito and the ruling elite feared the loss of political power by either foreign aggression or from domestic groups challenging the Communist Party’s (LCY) claim to govern, they fought hard for the reform of Marxism. Furthermore, Yugoslav elites manipulated popular conceptions of a Yugoslav identity as a means to solidify their regime with a unifying and progressive identity. Citing elite perceptions of the Yugoslav system—including key aspects of central institutions such as the LCY and the military— this dissertation attempts to reconcile how leaders of a country that scholars have dismissed as full of national hatreds had constructed a functioning and popular system for so long

Full textThe purpose of this master thesis was to develop a methodology, which would assure an efficient way to use computing grids for computer models modeling biocatalytic processes. After researching possibilities to use computing grids for modeling of such processes, a methodology was presented, which can be used independently of grid middleware. Methodology was implemented on BalticGrid. By applying this methodology biocatalytic processes in biosensors were investigated. Operation of biosensor is described with mathematical model, which in general case is solved with computer model. Computer models of biosensors are commonly parameterized, and in most cases same problem is being solved only with different set of parameters. Such processes can be solved by using computational grids. Methodology presented in this paper was used to compare quasi steady state and detailed models of chemically modified biosensors. After examining methodology presented in this paper it was proved that this methodology can be used efficiently to research biocatalytic processes. Effectiveness of applying this methodology in concrete computational grid was estimated and suggestions were presented how to apply this methodology in an efficient way.

Then either G is solvable by finite or G contains a noncyclic free subgroup. This theorem was proved by J. Tits in 1972 [4], was considered by the mathematician J.P. Serre, as one of the most important algebra results of the XX century. When we say an elementary proof, we absolutely not mean a simple proof. We will follow the simplified proof of John D. Dixon

Full textActualmente existe uma grande reflorestação do território nacional, em que as florestas de monoculturas substituem aos poucos as florestas mais diversificadas e complexas. Neste estudo, um dos principais objectivos foi comparar os parâmetros reprodutores do Chapim-real Parus major e do Chapim-azul Cyanistes caeruleus entre uma floresta nativa de folhosas, uma floresta mista dominada por espécies exóticas e duas florestas de monocultura – pinhal e eucaliptal, bem como a influência da orla florestal. O estudo teve por base caixas ninhos para monitorização dos parâmetros reprodutores das duas espécies e das variáveis que podem influenciar a ocupação das mesmas. Os resultados demonstraram que as características dos diferentes tipos de florestas influenciam o uso das caixas ninhos, assim como a localização geográfica das mesmas. Demonstraram ainda que a floresta nativa não é a que melhores condições oferece para as duas espécies em estudo, mas sim a floresta que possui maior complexidade e diversidade vegetal, ou seja a floresta mista. As elevadas densidades e a competição pelo alimento nas florestas mais complexas, levam a uma diminuição do sucesso reprodutor dos chapins. Assim, os eucaliptais apresentam capacidade de suportar a avifauna, desde que algumas medidas simples sejam aplicadas, como por exemplo a colocação de caixas ninho, podendo mesmo adquirir maior potencialidade e adequabilidade para estas espécies do que os pinhais. À semelhança do que acontece em muitas outras espécies da fauna, a orla florestal, pela sua peculiaridade e heterogeneidade de espécies e espaços, confere algumas vantagens aos indivíduos que as utilizam, traduzindo-se por vezes num aumento do seu sucesso reprodutor.
Nowadays, there’s a high part of the national territory, where monoculture forest replaces gradually the more complex and diversified forests. In this study, one of the main objectives was to compare the reproductive parameters of the great tit Parus major and the blue tit Cyanistes caeruleus among the native broadleaf forest, the mixed forest dominated by exotic species and two monoculture forests - pine and eucalyptus forests, as well as the influence of forest edge. The study involved the use of nest boxes to monitor the breeding parameters of both species and of the variables that can influence its occupancy. The results show that the characteristics of different forest types influence the nest boxes use, as well as its geographical location. It was also demonstrated that the native forest isn’t the forest which offers the best conditions for the two studied species, instead was the forest that has a greater plant complexity and diversity, i.e. the mixed forest. The high densities and the food competition in the more complex forests, decreases the breeding success of the tits. Thus, eucalyptus forests have the capacity to withstand the avifauna, since some simple measures are applied, such as the nest box placement, and may even acquire more capability and suitability for these species than the pine forest. As in the case of many other fauna species', the forest edge, due to its uniqueness and diversity of species and spaces, gives some advantages to individuals which use it, sometimes leading to an increase in its reproductive success.

Petiveria alliacea L. à um arbusto da famÃlia Phytolaccaceae, usada popularmente na medicina folclÃrica para o tratamento de uma ampla variedade de doenÃas nas AmÃricas do Sul e Central. As fraÃÃes acetato (FA), hexÃnica (FH), hidroalcoÃlica (FHA) e hidroalcoÃlica precipitada (FHAppt) da raiz do tipi foram estudadas para investigar suas propriedades farmacolÃgicas, nos modelos de nocicepÃÃo (contorÃÃes abdominais induzidas por Ãcido acÃtico, formalina a 1% e placa quente) e nos modelos comportamentais clÃssicos (campo aberto, labirinto em cruz elevado- LCE, rota rod, tempo de sono induzido por pentobarbital, nado forÃado e convulsÃes induzidas por pentilenotetrazol- PTZ). Foram analisados tambÃm os fitoconstituintes presentes no tipi, os efeitos farmacolÃgicos gerais e sua toxicidade aguda. As fraÃÃes foram administradas, via oral (v.o.) e/ou intraperitoneal (i.p.), nas doses de 100 e 200 mg/kg, em camundongos fÃmeas. A abordagem fitoquÃmica das fraÃÃes de Petiveria alliacea revelou a presenÃa de alcalÃides em FA, cumarinas em FA, FHA e FHAppt, saponinas e triterpenos em FA, FH, FHA e FHAppt. O extrato hidroalcoÃlico (500, 1000, 1500 e 2000 mg/kg, i.p.; 1000, 2000, 3000 e 4000 mg/kg, v.o.) do tipi apresentou uma baixa toxicidade e os parÃmetros mais visualizados foram analgesia, diminuiÃÃo da motilidade e passividade. Todas as fraÃÃes inibiram as contorÃÃes abdominais induzidas por Ãcido acÃtico. FA (200 mg/kg, i.p.), FH e FHAppt (100 e 200 mg/kg, i.p.), reduziram a nocicepÃÃo produzida pela formalina na 1 e 2 fases. FHA (100 e 200 mg/kg, i.p.) apresentou uma inibiÃÃo significativa na 1 fase deste teste, indicando um possÃvel efeito antinociceptivo. O efeito antinociceptivo produzido por FHAppt (200 mg/kg, i.p.) foi revertido pela naloxona (2mg/kg, s.c.), mostrando uma possÃvel participaÃÃo do sistema opiÃide neste processo. Nenhum efeito significativo foi observado no teste da placa quente. Todas as fraÃÃes do tipi induziram uma diminuiÃÃo significativa na atividade locomotora, rearing e grooming no teste do campo aberto, sugerindo uma possÃvel aÃÃo depressora central. Nenhum efeito significativo foi evidenciado na coordenaÃÃo motora dos animais no teste do rota rod. No LCE, FA (100 e 200 mg/kg, v.o.) reduziu o NEBA (n de entradas nos braÃos abertos) e o TPBA (tempo de permanÃncia nos braÃos abertos). FA, FH e FHA (100 e 200 mg/kg, i.p.), FHAppt (200mg/kg, i.p.) apresentaram uma significativa reduÃÃo do TPBA, indicando uma ausÃncia do efeito ansiolÃtico. As fraÃÃes da raiz de Petiveria alliacea promoveram um aumento significativo do tempo de imobilidade dos camundongos no teste do nado forÃado. AlÃm disso, corroborando estes resultados, as fraÃÃes causaram um prolongamento do tempo de sono induzido por pentobarbital, confirmando um provÃvel efeito sedativo e depressor central. Os efeitos neurofarmacolÃgicos de FHA (200 mg/kg, i.p.), observados nos testes do campo aberto e tempo de sono, nÃo foram revertidos com a administraÃÃo de flumazenil (2,5 mg/kg, i.p.), indicando que o mecanismo de aÃÃo de FHA, provavelmente, nÃo està relacionado com a participaÃÃo dos receptores GABAÃrgicos. Todas as fraÃÃes da raiz de Petiveria alliacea aumentaram a latÃncia da 1 convulsÃo e o tempo de morte das convulsÃes induzidas por PTZ nos animais, confirmando seu uso popular como anticonvulsivante. Os resultados mostraram que as diferentes fraÃÃes de Petiveria alliacea L. possuem significativo potencial antinociceptivo, sedativo, depressor e anticonvulsivante, devido à presenÃa destes constituintes, dando suporte ao uso da medicina folclÃrica desta planta.
Evaluation of the central and antinociceptive effects of isolated fractions from the root of Petiveria alliacea L. (tipi) in mice. PATRÃCIA BEZERRA GOMES. Supervisor: Profa. Dra. Francisca ClÃa FlorenÃo de Sousa. Master Dissertation. Course of Post-graduation in Pharmacology. Department of Physiology and Pharmacology, UFC, 2006. Petiveria alliacea L. a shrub from Phytolaccaceae family, is popularly used in folk medicine for treating a wide variety of disorders in South and Central America. The acetate (FA), hexanic (FH), hydroalcoholic (FHA) and precipitated hydroalcoholic (FHAppt) fractions from the root of tipi were studied to investigate its pharmacological properties in animals nocicepcion models (abdominal contractions induced by acetic acid, formalin 1% and hot plate tests) and in the classical behavioral models (open-field, elevated plus maze- EPM, rota rod, barbiturate-induced sleeping time, forced swimming and pentylenetetrazole (PTZ)-induced convulsions tests). Were analyzed the phytoconstituents presents in it, the general pharmacological effects and acute toxicity. The fractions were administered orally (p.o.) and/or intraperitoneally (i.p.), at single doses of 100 and 200 mg/kg, in female mice. The phytochemical approach of the fractions from Petiveria alliacea demonstrated the presence of alkaloids in FA, coumarins in FA, FHA and FHAppt, saponins and triterpenes in FA, FH, FHA and FHAppt. The hidroalcoholic extract (500, 1000, 1500 and 2000 mg/kg, i.p.; 1000, 2000, 3000 and 4000 mg/kg, p.o.) of the tipi presented a low toxicity and the parameters more visualized were analgesic, decrease in locomotor activity and passive behavior. All the fractions inhibited the abdominal contractions induced by acetic acid. FA (200 mg/kg, i.p.), FH and FHAppt (100 and 200 mg/kg, i.p.), reduced the nocicepcion produced by formalin in the 1st and 2nd phases. FHA (100 and 200 mg/kg, i.p.) presented a significant inhibition on the 1st phase, of this test, indicating a possible antinociceptive effect. The antinociceptive effect produced by FHAppt (200 mg/kg, i.p.) was reversed by naloxone (2 mg/kg, s.c.), showing the participation of the opioid system in this process. No significant effect was observed in the hot plate test. All the fractions of tipi induced a significant decrease in the locomotor activity, rearing and grooming in the open field test, suggesting a possible central depressant action. No significant effect was evident on motor coordination of the animals in the rota rod test. On LCE, FA (100 and 200 mg/kg, p.o.) decreased the NEOA (n of entries in the open arms) and the TPOA (time of permanence in the open arms). FA, FH and FHA (100 and 200 mg/kg, i.p.), FHAppt (200mg/kg, i.p.) presented a significant reduction of the TPOA, indicating an absence of anxiolytic effect. The fractions from the root of Petiveria alliacea promoted a significant increase in the immobility time of the mice in the forced swimming test. Moreover, corroborating these results, as caused a prolongation of the pentobarbital-induced sleeping time, confirmed a probable sedative and central depressant effect. The neuropharmacological effects of the FHA (200 mg/kg, i.p.), observed in the open field and barbiturate-induced sleeping time tests, werenât reverted with the administration of the flumazenil (2.5 mg/kg, i.p.), indicating that the mechanism of action of the FHA, probably didnât related with the participation of the GABAergic receptors. All the fractions of Petiveria alliacea increased the latency to the first convulsion and the lethal time of the PTZ-induced convulsions test in the animals, confirmed its popular use as anticonvulsant. Results showed that the different fractions of Petiveria alliacea L. have significant antinociceptive, sedative, depressant and anticonvulsant potentials, due to presence in this constituents, supporting folk medicine use of this plant.

Full textTitin is a giant protein expressed in both skeletal muscles and heart. Several pathogenic mutations were identified in its last coding exon. The most frequent mutation commonly referred to as FINmaj, results in the replacement of 4 amino acids and affects a subset of patients in Finland. The mutation causes a Tibial Muscular Dystrophy (TMD) when present on one allele and a Limb Girdle Muscular Dystrophy phenotype 2J (LGMD2J) when present on both alleles.To obtain a model for studying the physiopathology of these diseases and evaluating therapeutic strategies, we introduced the FINmaj mutation in the murine genome by a knock-in strategy by homologous recombination. This model was characterized and showed that it reproduces mainly the symptoms of both the human TMD and LGMD2J at histological and molecular levels.The study of this mouse model has allowed a better understanding of the pathophysiology of these two diseases and we have to study more carefully the interactions beyond titin C-ter with its partners to better understand the involvement of the M line in life of the sarcomere.The study of the pathophysiology of TMD and LGM2J showed that calpain 3 (a protease thatlind to an other limb-girdle muscular dystrophy), played a major role in TMD. This finding allowed us to consider a treatment approach for TMD to reduce symptoms by regulating negatively calpain 3. A gene therapy approach was also tested: the trans-splicing of the last exon of titin.Indeed, given the large size of the cDNA of titin (~ 100 kb), conventional strategies of genetransfer were not envisaged. To overcome this problem, we tested an approach to exchange the last exon or the last exons of the titin messenger. We were able to demonstrate the correction of titin in vitro

Full textEste trabalho descreve o estudo dos componentes volÃteis e nÃo volÃteis das raÃzes de Petiveria alliaceae, incluindo as atividades nematicida e inseticida do Ãleo essencial. Para o estudo quÃmico, fitonematicida e inseticida utilizou-se as raÃzes da planta, das quais foram obtidos o Ãleo essencial e os constituintes nÃo-volÃteis. Do Ãleo essencial das raÃzes foram identificados os seguintes componentes: benzaldeido (61,5%) (constituinte majoritÃrio) dissulfeto de dibenzila (18,1%), transestilbeno (14,1%) e cinamaldeido (6,3%), sendo que esses dois Ãltimos compostos tambÃm foram isolados atravÃs de cromatografia em camada delgada preparativa e identificados por RMN 1H e 13C. O tratamento cromatogrÃfico dos extratos etanÃlico, acetato de etila e hexÃnico permitiu o isolamento de uma mistura de duas mercaptanas, dissulfeto de dibenzila e o trissulfeto de dibenzila, dissulfeto de dibenzila, uma alantoina e a sacarose, que pela primeira vez foram isoladas das raÃzes de Petiveria alliaceae. As mercaptanas isoladas sÃo conhecidas na literatura por suas atividades fungicidas e nematicida. O Ãleo essencial extraÃdo das raÃzes de P. alliaceae e seus constituintes foram submetidos aos ensaios de atividades nematicida contra larvas de Meloidogyne incÃgnita (nematÃide de galhas) e inseticida contra a Mosca branca (Bemisia tabaci) inseto do feijÃo (Callosobruchus maculatus). Os Ãleos essenciais obtidos de P. alliaceae coletadas nas duas localidades diferentes apresentaram significantes atividades inseticida e nematicida. Os constituintes isolados tiveram suas estruturas elucidadas atravÃs de mÃtodos espectromÃtricos de IV, EM, RMN 1H e 13C uni e bidimensionais (COSY, HMQC e HMBC).
This work describes the study of the volatile and the non-volatile components from the roots of Petiveria alliaceae, including the nematicidal and insecticidal activities of the essential oil. The following components were identified in the essential oil: benzaldehyde as the major constituent (61, 5 %), cinnamaldehyde (6, 3%), dibenzyl disulphide (18, 1%), transstilbene (14, 1%). The two last compounds were also isolated through a chromatography in a preparative thin layer identified by RMN 1H and 13C. The isolation of a mixture of two mercaptans, benzyl disulphide and dibenzyl trisulphide, saccharose and allantoin, which were isolated for the first time from the Petiveria alliaceae, was permitted by the chromatographic treatment of the ethyl acetate, hexane, and ethanolic extracts. The isolated mercaptans are known in literature for their fungicide and insecticide activities. The constituents of the essential oil, extracted from the roots of Petiveria alliaceae, were submitted to the nematicidal activities against Meloidogyne incognita larva, insecticide against white fly (Bemisa tabaci) and insect of the beans (Callosobruchus maculatos). Significant insecticidal and nematicidal activities were present in the essential oil from the P. alliaceae, collected in two different localities. The isolated constituents had their structure elucidated through spectrometric methods of IV, EM, RMN 1H and 13C uni and bi-dimensional (COSY, HMQC and HMBC)

C. To see the effect of cold working
prior to intermediate annealing, 20 % or 40 % cold work was applied to another group of specimens. To study the shape memory characteristics of specimens subjected to the above mentioned processes, four types of test, namely constant stress free recovery test, constant strain free recovery test, constant stress constrained recovery test and constant strain constrained recovery test, were designed and applied cyclically. The tests have shown that the stress plateau observed in the first cycle of the tests disappear upon cycling and the shape memory characteristics improve and stabilize with cycling. Once trained by cycling, fractional free recovery was observed to reach to 100 % and recovery stress to reach 120% of the applied stress if shape recovery is prevented.

Full textThe study of most of the narratives dealing with violence and conflicts in the work of livy reveals the existence of recurrent patterns essentially based on duality and on mimesis. The sacred is of great importance in these narratives : it explains, it justifies and it sublimates violence. It also contributes to turn some of the protagonists into heroes and their adversaries into transgressors. The violence of the formers becomes then positive and contributes to create or to maintain order. The narratives have two kinds of different, apparently opposed issues : those based upon exclusion patterns and those based upon synthesis. However, in spite of their diversity, these different issues are linked ; they illustrate in fact the same ideology. The importance of the discourse on violence is also revealed by the study of the institutions, and more particularly by the study of kingship. Here again a fundamental role is played by the sacred and by the patterns of duality which seem to be, well beyond livy, a part of the roman world vision
