1. Petrography and detrital zircon U-Pb geochronology of sedimentary rocks of the Campo Alegre Basin, Southern Brazil: implications for Gondwana assembly
Abstract The Campo Alegre Basin is a volcano-sedimentary sequence covering an area of about 500 km 2 , located at the northeast portion of Santa Catarina state (Brazil), and formed during the late stages of the Neoproterozoic era. Three main stratigraphic units compose this basin, the lowermost of which is the Bateias Formation, corresponding to the pre-volc

2. COX-2 gene expression and methylation profile in Sapajus apella as an experimental model for gastric adenocarcinoma
Abstract Gastric cancer (GC) remains one of the main causes of cancer-related death worldwide. There are two distinct histological types of GC: diffuse and intestinal. The latter is characterized by the presence of pre-neoplastic lesions. One of the most frequently altered enzymes in intestinal GC is COX-2, an important lesion marker. This work aimed to stud

3. Detection and molecular characterisation of a diagnosis escape variant associated with occult hepatitis B virus in Brazil
BACKGROUND Many studies have identified mutations in the hepatitis B surface antigen (HBsAg) as important factors limiting the ability of commercial serological assays to detect this viral antigen. However, an association between mutations in the HBsAg gene and the occurrence of occult HBV infection (OBI) in patients has not been established. OBJECTIVES

4. Envoltórios circunstelares de estrelas jovens de massa intermediária / Circumstellar envelopes of intermediate mass young stars
As estrelas Herbig Ae/Be (HAeBe) representam os objetos de massa intermediária (2-10 Msol) na pré-sequência principal. Algumas de suas propriedades físicas são pouco compreendidas até o momento. Somente o estudo conjunto das informações fornecidas em diversos comprimentos de onda pode revelar as características do material circunstelar destes objeto

5. Formação estelar no complexo de nuvens moleculares em Monoceros / Star Formation in the Molecular Cloud Complex in Monoceros
We compare two molecular clouds of the Monoceros Complex in order to study their physical conditions related to the early stages of star formation. The selected clouds, Rosette (RMC) and Monoceros R2 (Mon R2), are interesting regions due to their characteristics that may be confronted with the hypothesis of star formation triggered by high velocity clouds (H

7. Efectos acústicos inmediatos de una secuencia de ejercicios vocales con tubos de resonancia
PURPOSE: the purpose of this study is to determine the immediately acoustic effect of phonatory exercise sequence using resonance tubes in a group of dysphonic subjects METHOD: a unique sequence of four phonatory tasks within resonance tubes was applied in twenty-four teachers with dysphonic voices, assessed perceptually with GRBAS scale. Voice samples were

8. Tecnologia lítica: estudo da variabilidade em sítios líticos do nordeste do estado de São Paulo / Lithic Technology: a study of assemblage variability on lithic archaeological sites in Northeastern São Paulo State
The main objective of this research is the study of the production technology of chipped stone artifacts and their operational sequence on lithic archaeological sites located in Northeastern São Paulo State. A bibliographic research was made based, firstly, on the amateur and specialized archaeological literature related to this specific subject, paying att

9. Simulações Numéricas Tri-dimensionais de Ventos Magnetizados de Estrelas de Baixa Massa / Three-Dimensional Numerical Simulations of Magnetized Winds of Low-Mass Stars
O tópico abordado nesta tese é a perda de massa através de ventos coronais magnetizados em estrelas de baixa massa. Ventos estelares têm sido estudados extensivamente há vários anos, tendo inicialmente como foco o vento solar. Atualmente, sabe-se que o campo magnético é essencial na aceleração e aquecimento dos ventos coronais. Apesar do conhecimen

10. A Formação de Padres no Nordeste do Brasil (1894-1933)
The Nossa Senhora da Conceição Seminary, installed in 1894, by Dom Adauto Aurélio de Miranda Henriques, first Paraíba Bishop, and the Episcopal Seminary of the Sagrado Coração de Jesus, implanted in 1913, by Dom José Thomas Gomes da Silva, first Aracajus Bishop diocese, were created as a result of lack of an official religious process proposed by the

11. Caracterização tectono-estratigráfica da sequência transicional na sub-bacia de Sergipe
This thesis deals with the tectonic-stratigraphic evolution of the Transitional Sequence in the Sergipe Sub-basin (the southern segment of the Sergipe-Alagoas Basin, Northeast Brazil), deposited in the time interval of the upper Alagoas/Aptian stage. Sequence boundaries and higher order internal sequences were identified, as well as the structures that affec

12. Efeitos da distribuição da prática sobre a aquisição de habilidade motoras por adultos jovens e idosos
Human motricity undergoes modifications throughout the lifespan. Aging processes brings in changes which are relevant to practice organization, which makes practice scheduling (massed-distributed) a factor to be considered as it may influence information processing and memory consolidation. The main purpose of this study was to investigate practice schedulin
