It proposes models of problems and solutions for legal phenomenon of tax avoidance from the inference by analogy of the fundamental right of tax freedom. In addition to a subjective dimension, this unenumerated right has an objective dimension, which unfolds in interpretative and protection duties, and a broad statement of facts, which permits the practice of neutral economic relations to the greatest extent possible. Based on the principle of ability to pay, the Brazilian tax system restricts the fundamental right of tax freedom by specific anti-avoidance rules and general anti-avoidance rule. Mobile anti-avoidance rules arise as a third way to promote the stability and predictability values and to reduce the administrative and judiciary discretions. / Em face da crise paradigm?tica, a teoria sistem?tica da elis?o tribut?ria prop?e modelos de problemas e de solu??es para o fen?meno jur?dico da elis?o tribut?ria com base na infer?ncia por analogia do direito fundamental da liberdade fiscal. Na condi??o de direito fundamental n?o enumerado, a liberdade fiscal tem uma dimens?o objetiva, que se desdobra em deveres de interpreta??o conforme e de prote??o, e um suporte f?tico ilimitado, que permite a pr?tica de rela??es econ?micas neutras na maior medida poss?vel. ? luz do princ?pio da capacidade contributiva, o sistema tribut?rio brasileiro disp?e restri??es legislativas da liberdade fiscal atrav?s de regras espec?ficas de antielis?o tribut?ria e da cl?usula geral de antielis?o tribut?ria.

The phylogenetic relationships among its members have been historically unstable, with frequent taxonomic changes at the family level due to the recurrent presence of paraphyletic taxa. However, an increase of studies based on morphological and molecular data has built a scaffold of information about the evolutionary relationships among caecilians; even though, a phylogenetic classification of the order has remained a challenge. In 2011 a new taxonomy of Gymnophiona was proposed, where genera were arranged in nine families supposedly monophyletic. This taxonomy was not based on a phylogenetic analysis but on a consensus of the understanding of the evolutionary relationships of the group as inferred by previous studies. However, important conflicts exits among the results and type of analyses performed on these studies. Furthermore, only one study has included the known fossil taxon of Gymnophiona, which despite being fragmented is a valid source of evidence. Due to several and continuous efforts to generate data on caecilians, there is a wealth of hereditary characters available for phylogenetic studies. Thus, it has become crucial to perform a combined analysis of all these data (complete mitochondrial genomes, nuclear DNA sequences, phenotypic characters of extant and fossil taxa) to obtain a phylogenetic hypothesis that maximizes explanatory power. The objective of this study is to infer the evolutionary relationships of Gymnophiona based on a total evidence analysis using parsimony and dynamic homology to evaluate the current taxonomy of the group. Additionally, we also evaluate the effect of different types of alignment (tree versus similarity approaches), the influence of phenotypic characters on a dataset dominated by molecular characters, and the effect of coding indels as missing data. We compiled previously published phenotypic characters, DNA sequences available from GenBank of 47 nuclear and mitochondrial genes of all available taxa, and produced 42 new sequences. When comparing the results obtained from the tree-alignment analysis in POY with those of the similarity alignment in TNT, both recover Rhinatrematidae as sister of Ichthyophiidae + Teresomata. Within Rhinatrematidae, Epicrionops is paraphyletic in all analyses and the relationships within Ichthyophis are unsolved (a polytomy in the strict consensus). POY does not recovered Scolecomorphidae as the sister taxon of all other Teresomata but Typhlonectidae + Caeciliidae. Caecilia is paraphyletic with respect to Oscaecilia and Typhlonectes in relationship to Potamotyphlus. Scolecomorphidae is sister of Herpelidae + Chikilidae. The results of TNT recover a paraphyletic Herpelidae, with Herpele squalostoma sister of Chikilidae. Also, Siphonopidae is non-monophyletic. Indotyphlidae is non-monophyletic in both analyses and Idiocranium is consistently recovered as sister taxon of Dermophiidae. Dermophis is recovered as paraphyletic in the POY analysis, while both Dermophis and Gymnopis are paraphyletic in the TNT analysis. The strict consensus of the molecular dataset is highly congruous with that of the total evidence dataset; however, the former is better resolved (less polytomies), mainly within Indotyphlidae. The analysis of the phenotypic data alone resulted in a complete polytomy, illustrating the need of more research in this avenue. Coding indels as missing data did not cause important topological changes. The main conclusions derived from this study are: (i) the type of alignment of DNA sequences have an evident impact on the phylogenetic hypotheses of Gymnophiona; (ii) the apparent resolution on the evolutionary relationships of the extant supraspecific taxa of Gymnophiona and their monophyly presented in other studies are dependent on the exclusion of relevant evidence?taxa and characters?or the partial presentation of the optimal hypotheses; (iii) only a total evidence analysis allowed us to discover some of the potential cases of paraphyly or misidentification of vouchers; (iv) the phenotypic data currently used in the study of the evolutionary relationships of Gymnophiona contain important levels of non-congruent information and are not sufficient to place the fossil Eocaecilia micropodia within caecilians. This study reveals the need of detailed revision of the taxonomy and phylogeny of Gymnophiona. / Gymnophiona M?ller, 1832 ? a ordem menos estudada dentro de Amphibia, com 206 esp?cies conhecidas. As rela??es filogen?ticas do grupo permaneceram inst?veis por muito tempo, sofrendo com mudan?as no n?mero de fam?lias, devido ? constante presen?a de t?xons parafil?ticos. Uma crescente de estudos com produ??o de evid?ncias moleculares e morfol?gicas tem formado um arcabou?o de informa??es sobre as rela??es evolutivas do grupo. Mesmo assim, uma classifica??o filogen?tica de toda a ordem n?o representava uma tarefa f?cil. Em 2011, foi proposta uma classifica??o ao n?vel de fam?lia, onde os g?neros foram distribu?dos em nove fam?lias supostamente monofil?ticas. Essa proposta n?o foi baseada em uma an?lise filogen?tica, mas sim em um consenso do entendimento das rela??es filogen?ticas inferidas em estudos pr?vios, sendo muitos deles discordantes, tanto em tipos de an?lises, quanto em resultados. Apenas um estudo incluiu um t?xon f?ssil, que apesar de ser pouco representativo em quantidade, representa uma fonte v?lida de evid?ncia. Devido ao grande esfor?o para gerar dados e obter informa??es acerca dos Gymnophiona, existem in?meros caracteres heredit?rios dispon?veis. Dessa forma, percebe-se uma import?ncia em unir todos esses dados (genomas mitocondriais completos, sequ?ncias de genes nucleares, caracteres fenot?picos dos t?xons viventes e f?ssil) para compor uma nova proposta filogen?tica com o maior poder explicativo. Assim, o objetivo principal deste estudo foi inferir as rela??es evolutivas da ordem Gymnophiona em um contexto de evid?ncia total, sob an?lises de parcim?nia e homologia din?mica e avaliar a taxonomia atual de Gymnophiona com base na(s) ?rvore(s) mais parcimoniosa(s). Adicionalmente, avaliar o efeito de diferentes tipos de alinhamento, a influ?ncia de caracteres fenot?picos em um dataset dominado por dados gen?ticos e o efeito de codificar os indels como dados faltantes. Para isso foram compilados caracteres morfol?gicos de estudos pr?vios, sequ?ncias dispon?veis no GenBank, referentes a 47 genes (nucleares e mitocondriais) de todas as esp?cies dispon?veis, al?m da produ??o de 42 novas sequ?ncias. Comparando os resultados gerados a partir do alinhamento por ?rvore (POY) e do alinhamento por similaridade (TNT) encontramos Rhinatrematidae como grupo-irm?o de Ichthyophiidae + Teresomata. Dentro de Rhinatrematidae, Epicrionops foi recuperado parafil?tico em todas as an?lises e as rela??es dentro de Ichthyophiidae s?o uma politomia. A an?lise do POY n?o recupera Scolecomorphidae como t?xon-irm?o dos demais Teresomata, e sim Typhlonectidae + Caeciliidae. Caecilia ? parafil?tica a Oscaecilia, assim como Typhlonectes com rela??o a Potamotyphlus. Na an?lise via TNT, Herpelidae foi recuperada parafil?tica, com Herpele squalostoma agrupado com Chikilidae. Na an?lise do TNT, Siphonopidae n?o foi recuperada monofil?tica. A fam?lia Indotyphlidae foi n?o-monofil?tica em ambas as an?lises e Idiocranium foi recuperado como o t?xon-irm?o de Dermophiidae. Dermophis surge parafil?tico na an?lise do POY, enquanto que pelo TNT tanto Dermophis quanto Gymnopis surgen parafil?ticos. A topologia da ?rvore constru?da apenas com sequ?ncias de DNA, mostrou-se altamente semelhante ao consenso gerado pelo TNT, embora com alguns poucos clados melhor resolvidos, principalmente em Indotyphlidae. J? a an?lise unicamente morfol?gica restringiu-se a uma politomia total, o que pode ser justificado pela falta de caracteres morfol?gicos ?teis, e que tamb?m pode ser um reflexo da falta de conhecimento acerca deste tipo de evid?ncia. Quanto ? codifica??o de indels como quinto estado ou como dados faltantes, n?o foi observada vantagem sobre nenhum dos testes em rela??o ? topologia do consenso estrito. As principais conclus?es derivadas dos resultados obtidos s?o: (i) o tipo de alinhamento das sequ?ncias de DNA tem um impacto evidente nas hip?teses filogen?ticas; (ii) a aparente resolu??o da hist?ria evolutiva dos atuais t?xons supraespec?ficos de Gymnophiona e sua monofilia, apresentada em outros estudos, dependem da exclus?o de evid?ncia relevante das an?lises ou da apresenta??o parcial das hip?teses ?timas; (iii) s? a an?lise de evid?ncia total permitiu descobrir casos potenciais de parafilia ou identifica??o errada de terminais; (iv) os dados fenot?picos atualmente usados no estudo das rela??es evolutivas de Gymnophiona t?m altos n?veis de informa??o n?o congruente e n?o s?o suficentes para a inclus?o do t?xon f?ssil Eocaecilia micropodia dentro de Gymnophiona. O presente estudo revela a necessidade de uma revis?o detalhada da taxonomia e filogen?tica de Gymnophiona.

The research has, as a tool, the Summa Theologiae and the commandments of charity, written later, in the commandments. The theme discussesthe Lord s daily life in the context of the commandments, trying to understand the reflection of St Thomas Aquinas s Law (eternal, natural, human, old and new). This action leads to the Day of the Lord in the third commandment of Act of God, taking into consideration the biblical concept of the Exodus and Deuteronomy, making use of the theological elements of the ancient law and the new one given by Jesus Christ in the commandment of love to God and to the others. Thomas suggests sanctification as a central element of the Day of the Lord, which is a Day of Worship, in honor of God as well as end of the slave labor, in order to serve the Lord in community and celebrate His presence in Eucharist. / Esta Disserta??o, apresentada para o Mestrado em Teologia, ? uma reflex?o sobre a Teologia do Dia do Senhor em Santo Tom?s de Aquino.

We face the need to know the religious situation of the college students at The Pontifical Catholic University of Rio Grande do Sul, and how the actual crisis on faith affects them. We understand that the opinion of PUC students represent the opinion of college students in general, due to the fact they come from different places throughout the state and even from outside Rio Grande do Sul. Because of that they have received their upbringing in diversified environments, from both a family and cultural point of view. Society nowadays is going through a deep religious crisis, due to the emptying of our Churches. While old certainties and habits are being dissolved, new experimentations are coming up and they are insecure and hesitating. Therefore, many people believe in God as a superior and safe power, but don t have a religious belonging. The reality of religions in the country has changed in the last decades with the progressive decline of catholicism and the increase of religious pluralism in society, also the increase of syncretism, secularization, desacralization, atheism, religious indifference, etc. The most discussed issues, such as divorce, abortion, natality control, genetic human research, artificial insemination, the union of people from the same sex, etc bring up new questions regarding the updating of the church nowadays. There is also an advance in science and its discoveries and people can now live without feeling threatened. People can and should live in harmony between faith and reason without this being a contradiction. This research tries to identify to what extend these trends can have an influence in the understanding of faith. It also points out at new pastoral movements that can respond to the actual challenges of this moment of postmodernity that we are living. / A pesquisa visa a conhecer a religiosidade e a pr?tica religiosa dos estudantes da PUCRS. Estamos diante da necessidade de conhecer a situa??o religiosa dos universit?rios da Pontif?cia Universidade Cat?lica do Rio Grande do Sul e verificar se a crise de hoje sobre a f? n?o deixa de afet?-los tamb?m. Entendemos que os alunos da PUCRS representam a opini?o dos universit?rios em geral, visto serem provenientes de diversos lugares do estado e at? fora do Rio Grande do Sul e, por esta raz?o, terem recebido educa??o b?sica em ambientes diversificados, considerando o ponto de vista familiar e cultural. A sociedade passa hoje por uma profunda crise religiosa, haja vista o esvaziamento de nossas Igrejas, onde velhas certezas e h?bitos se dissolvem e novas experimenta??es surgem titubeantes e inseguras. Assim sendo, muitos creem em Deus como uma for?a segura e superior, mas, sem uma perten?a religiosa. A realidade das religi?es no pa?s modificou-se nas ?ltimas d?cadas, com progressivo decl?nio do catolicismo e o aumento do pluralismo religioso na sociedade, do sincretismo, seculariza??o, dessacraliza??o, ate?smo, indiferentismo religioso, etc. As quest?es mais discutidas, como div?rcio, aborto, controle da natalidade, pesquisa gen?tica humana, insemina??o artificial, uni?o de pessoas do mesmo sexo, etc. trazem sempre novas indaga??es quanto ? atualiza??o da Igreja hoje. H? tamb?m um avan?o na ci?ncia e em suas descobertas, e o homem pode viver sem sentir-se amea?ado por isso. Deve e pode viver em harmonia entre f? e raz?o, sem que isso implique uma contradi??o. A pesquisa busca, portanto, identificar at? que ponto estas tend?ncias podem influenciar na compreens?o da f? e que, por sua vez, tamb?m apontem para novos movimentos pastorais que possam responder aos atuais desafios deste momento de P?s-modernidade, no qual que estamos vivendo.

Este trabalho tem como objetivo fazer um levantamento das traduções de obras de ficção em prosa de autores hispano-americanos publicadas no Brasil, tanto em coleções criadas com o fim específico de divulgar a literatura hispano-americana no país quanto em edições isoladas, fora de coleção. A análise principal está voltada para as coleções publicadas por diversas editoras brasileiras entre as décadas de 1960 e 1990, mas também serão analisadas algumas iniciativas editoriais anteriores e posteriores a estas décadas. Além do levantamento em si, o trabalho procura identificar o propósito editorial que norteou a tradução e publicação de autores hispano-americanos no Brasil, em cada momento histórico analisado, para tentar entender o que significou a circulação destas obras no sistema literário brasileiro. / The aim of this work is to do a survey of the prose fiction of Spanish-American authors translated to Portuguese and published in Brazil, not only in book collections or series created with the specif design of spreading the word about this kind of literature but also in individual editions. The core of the analysis is directed to some collections of Spanish-American Literature that were published in Brazil between the 1960's and the 1990's, although some other editorial efforts will also be analysed, both before and after this period of time. Beyond the survey itself, this work intends to identify the editorial purposes behind the translation and publication of books by Spanish- American authors in Brazil in each of the historical moments analyzed, in a attempt to understand the importance of the circulation of these books within the Brazilian literary system.

<p>Bakterije koje kolonizuju želudac (Gastrospirillum spp. i Helicobacter spp.) su izolovane kod čoveka i nekoliko animalnih vrsta, uključujući i svinje. Gastritis je rezultat prirodne ili eksperimentalno izazvane infekcije sa H. pylori kod čoveka i konvencionalnih prasića. Kod obe vrste (čovek i svinja), infekcija sa H. pylori pokreće inflamatorni odgovor organizma, međutim postoje razlike u ćelijskoj populaciji u inflamatornom infiltratu. Cilj istraživanja ove disertaciji je identifikacija bakterije Helicobacter spp., različite morfologije (Helicobacter-like organisms and Gastrospirillum-like organisms), kao i patohistolo&scaron;ki pregled i evaluacija gastritisa svinja uzgajanih na intenzivni i ekstenzivni način. Uzeti su uzorci mukoze pars oesophagea, fundusa i pilorusa. Za identifikaciju bakterije Helicobacter spp. kori&scaron;ćene su dve metode bojenja: Loefflermethylene blue i modifikovana Giemsa. Za histolo&scaron;ko ispitivanje, uzorci su obojeni i hematoksilin eozinom (H&amp;E). Stepen gastritisa je određen prema Sidnejskom sistemu za klasifikaciju gastritisa. U humanoj a i u veterinarskoj patologiji, dobro je poznata činjenica o različitoj patogenosti različitih bakterija Helicobacter vrsta. Helicobacter bakterije izolovane iz želuca svinja pripadaju različitim vrstama ovog roda i međusobno se bitno razlikuju kako po patogenosti, tako i po virulentnosti. Tako na primer, Helicobacter&ndash;like bakterije koje su okarakterisane kao visoko patogene, mogu izazvati ulceracije ezofagealnog ili glandularnog dela želuca, gastritis ozbiljnog stepena i formiranje limfoidnih folikula. Rezultati na&scaron;eg istraživanja pokazuju da je stepen gastritisa veći u piloričnoj mukozi HLO-pozitivnih svinja u poređenju sa vrednostima GLO-pozitivnih svinja. Nije postojala pozitivna korelacija između infekcije bakterijama GLO morfologije i ulceracija. Za razliku od perzistentnih infekcija sa H. pylori kod ljudi kod kojih je te&scaron;ka glandularna atrofija udružena sa intestinalnom metaplazijom veoma česta, kod ispitivanih svinja iz</p><p><br /><br />intenzivnog i ekstenzivnog načina uzgoja nisu potvrđeni slučajevi atrofičnog gastritisa i intestinalne metaplazije. Konvencionalne svinje mogu poslužiti kao animalni model infekcije sa H. pylori jer su svinje u funkcionalnom smislu monogastrične životinje po anatomskim i fiziolo&scaron;kim karakteristikama, vrlo slične čoveku. Takođe, patogeneza infekcije je veoma slična kao kod čoveka. Navedene činjenice podržavaju mogućnost upotrebe ovog modela u daljem istraživanju patogeneze nastanka Helicobacter spp. gastritisa. Rezultati ovog istraživanja pružaju dodatni dokaz da HLO mogu biti faktor koji igra krucijalnu ulogu u patogenezi gastritisa kod svinja.&nbsp;<br />Datum</p> / <p>Bacteria that colonize the stomach (Helicobacter spp. and Gastrospirillum spp.) are isolated from humans and several animal species, including pigs. Gastritis is the result of a natural or experimental induced infection with H. pylori in humans and conventionally pigs. In both, humans and pigs, the infection with H. pylori elicited inflammatory response, but there are differences between populations of inflammatory cells. The aims of this dissertation are to identify&nbsp; spp. with two different morphology (Helicobacter-like organisms and Gastrospirillumlike organisms), as well as histolopathological examination and evaluation of gastritis score of gastric mucosa of pigs in intensive and extensive production. Biopsy samples were taken from the pars oesophagea, fundic and pyloric mucosa. For identification of Helicobacter species morphology we used two stain methods: Loeffler-methylene blue and modified Giemsa. All tissue sections were stained with hematoxylin and eosin (H&amp;E) for histopathological evaluation. The severity of gastritis was scored to the Sydney System for the classification of gastritis. In human as well as in veterinary pathology, the fact of the different pathogenicity of various Helicobacter species is well known. The Helicobacter spp. isolated from stomach mucosa of pigs which belong to different genus, differ significantly in both, pathogenicity and virulence. Helicobacter pylori-like bacteria characterised as high pathogenic, has been associated with ulceration of the oesophageal or glandular portion of the stomach, severe gastritis and formation of lymphoid follicles. On the contrast, infection with Helicobacter heilmannii, which has been shown to have low pathogenicity was accompanied by only mild gastritis and no ulceration. The results of current study suggested that the average gastritis score was higher in HLO-positive pyloric mucosa, compared</p><p><br /><br />with the GLO-positive pyloric mucosa. There was signifficance between HLO-positive and HLO-negative pyloric mucosa in both, intensive and extensive production. There was no correlation between GLO-positive mucosa and ulceration. In contrast to persistent H. pylori infection in humans in which severe glandular atrophy associated with intestinal metaplasia is very common, in examined pigs from intensive and extensive breeding, no samples exhibited histological features characteristic for atrophic gastritis and intestinal metaplasia have been confirmed in pigs of both production systems. The conventional piglets as an animal model of the human H. pylori infection offers advantages of a functional monogastric animal with gastric anatomic and physiologic characteristics similar to those of humans. Moreover, the infection and pathogenesis is similar to that in humans. These facts support the usefulness of this model in further research on the pathogenic mechanisms of Helicobacter spp. associated gastritis.
