1. Comparison between Arch Zones in Modified Frozen Elephant Trunk Procedure for Complex Thoracic Aortic Diseases
Abstract Introduction: The aim of this study is to compare postoperative outcomes and follow-up of two different modifications facilitating surgical technique of frozen elephant trunk (FET) procedure for complex thoracic aortic diseases - zone 0 (fixation with total arch debranching) and zone 3 (fixation with islet-shape arch repair). Methods: From May 201

2. Making Place, Making Home: Lesbian Queer World-Making in Cape Town
Resumo: Duas narrativas dominantes e contrastantes passaram a caracterizar o discurso público sobre sexualidades queer na Cidade do Cabo. A Cidade do Cabo é considerada a capital gay da África do Sul. Simultaneamente, um enquadramento binário de zonas brancas de segurança e zonas negras de perigo (Melanie JUDGE, 2018) mostra ‘a lésbica negra’ atrav

3. Morphological and genetic perspectives of hybridization in two contact zones of closely related species of Petunia (Solanaceae) in southern Brazil
ABSTRACT Interspecific hybridization has several consequences for parental species, from blurring species limits to the emergence of new taxa. Petunia axillaris and P. exserta occur in sympatry in southernmost Brazil and naturally hybridize despite their different pollination syndromes and habitat requirements. We employed genetic and morphological analyses

4. Synthesis of New Reconfigurable Limited Size FSS Structures Using an Improved Hybrid Particle Swarm Optimization
Abstract This paper describes a new design methodology for reconfigurable printed circuits with limited size, using an improved hybrid particle swarm optimization (HPSO) algorithm, reducing the search space by the definition of negative zones (NZ), regions where the swarm of particles should not travel. The proposed design methodology (HPSO-NZ) is used in th

5. NPV analysis of multiple surface constraints for pit expansion scenarios under geological uncertainty
Abstract To optimize a mining project, it is necessary to deal with several technical aspects and constraints, such as orebody modelling, reserve estimation, blending strategy, optimal and operational pit designs, cost control, environmental issues, among others. In this sense, locating surface infrastructures is one of the most critical mine planning concer

6. A numerical study on seismic response of self-centring precast segmental columns at different post-tensioning forces
Precast bridge columns have shown increasing demand over the past few years due to the advantages of such columns when compared against conventional bridge columns, particularly due to the fact that precast bridge columns can be constructed off site and erected in a short period of time. The present study analytically investigates the behaviour of self-centr

7. Magmatic epidote and amphibole from the Rio Espinharas hybrid complex, Northeastern Brazil
The petrography and chemistry of epidote and amphibole from the Rio Espinharas hybrid complex (REHC), northeastern Brazil are reported. The Rio Espinharas complex is composed of an intimate association of diorite to shoshonitic metaluminous quartzmonzonite to slightly peraluminous syenogranite. The epidote shows four textural relationships: three are primary

8. The conservation status of the tuco-tucos, genus Ctenomys (Rodentia: Ctenomyidae), in southern Brazil / O status da conservação dos tuco-tucos, gênero Ctenomys (Rodentia: Ctenomyidae), no sul do Brasil
O objetivo da biologia da conservação deve estar relacionado com a preservação das espécies e também com os processos evolutivos e ecológicos que foram responsáveis por sua formação e que continuam ocorrendo. Este trabalho revisa o status de conservação das espécies de tuco-tuco (Ctenomys torquatus, C. lami, C. minutus e C. flamarioni) do sul do

9. Genetic structure of natural hybrid zones between Epidendrum fulgens and E. puniceoluteum (Orchidaceae) / Estrutura genética de zonas de hibridação natural entre Epidendrum fulgens e E. puniceoluteum (Orchidaceae)
Epidendrum L. é o maior gênero de Orchidaceae da região Neotropical com cerca de 1500 espécies, e os processos de diversificação no grupo são pouco conhecidos. Apesar de existirem muitos relatos sobre hibridação no gênero, não há trabalhos que tenham testado essa hipótese em populações naturais. Epidendrum fulgens Brongn. e E. puniceoluteum F.

10. Teias de significação: performance de língua-franca e narrativas vivenciadas de identidade / Web of significance: performance of lingua-franca and living narratives of identities
The present ethnographic research aims at investigating the complex of language, focusing on the performative character of language and the search for a lingua-franca as general aspects, as well as the role of the narrative mode as a particular aspect in the construction of identity, considering that it is composed by a complex of living experiences of body,

11. HEREDABILIDAD Y VALOR GENÉTICO (REML/BLUP) EN GENOTIPOS DE UN EUCALIPTO TOLERANTE A LA SEQUÍA, EN EL NORTE DE CHILE
ABSTRACT Few species of Eucalyptus are considered useful for forestation in arid zones. Eucalyptus cladocalyx is one of them, and it has been regarded in inter-specific hybrid programs for improvement characteristics like drought tolerance. 49 half-sib families from six populations were evaluated 30 months after the plantations in two localities of Chilean s

12. Resistencia ao cisalhamento por extrusão - "push out" - de pinos de fibra de vidro a dentina intra-radicular
The purpose of this study was to evaluate the bond strength between fiber posts cemented in root dentin considering different depths of the roots (cervical, median and apical) and two luting materiais, through push out tests and to examine the integration among these components through scanning electron microscopy. Twenty sound bicuspids, tree trom cracks, e
