Vaga-lume na treva: a poesia de João Lins Caldas

This thesis analyses the poetry of João Lins Caldas (1888-1967), in Brazilian literature context, aiming at describing and understanding the main features of his poetry. Thus, this research presents a corpus to be worked on: the poems in Poeira do céu e outros poemas (2009). Our study is characterized by a biographical, historiographical and critical tendency, by trying to organize the manuscripts of the author and biographical aspects while analyzing his poems. It is showed the relation between Brazilian poetry written by some authors, since the parnasianism and symbolism period until the twentieth century. On the one hand, our analysis is based on the ideas and criticism by Antonio Candido (2006; 2002; 1985), discussing the process of formation of Brazilian literature and the procedure to analyse poetry. It is also based on the concept of poetry and resistance, developed by Alfredo Bosi (2000; 2002), and the notion of Brazilian matter, identified by Roberto Schwarz (1987, 1997, 1999). On the other hand, this work focuses on melancholy under the theoretical ideas of authors such as Aristotle (1998), Walter Benjamin (1984), Jaime Ginzburg (1997) and Moacyr Scliar (2003). This focus on melancholy contributes to a better understanding of one of the main themes found in the poems analysed. By studying the poetry of João Lins Caldas, it was perceived the relevance of melancholy and resistance in his verses. This can be seen in his dissonant language, characterized by the broken syntax in his verses, as well as contradictory images and complex meanings in his poetry. This causes the effect of unfamiliarity on the reader. His poetry is the result of a style that finds its place in the best moment of modern Brazilian poetry and reveals its singularity through the inverted syntax with powerful themes such as love, death, pain, delusion, loss, memory, nature and God. All of them are aspects of Brazilian historicity. Finally, the work of João Lins Caldas is part of a multifaceted poetry

Análise de risco à erosão costeira na região de Tibau do Sul/RN através de mapeamento geoambiental e análise morfodinâmica

The research area is located on the county of Tibau do Sul, in the east coast of Rio Grande do Norte State, about 80km south of the capital Natal. The tourism represents the main income activity and Pipa beach is the most visited beach in the city, annually receives a large influx of domestic and foreign tourists. Some recent studies have reported the occurrence of coastal erosion in this littoral, being the main objective of the research, analyze the existing coastal erosion, through two methodologies, the geoenvironmental mapping and beach morphodynamics. The geoenvironmental mapping was done from oblique aerial photographs and field visits, which sought to carry out first the geomorphological mapping, with the purpose of analyzing features that suggest susceptible areas to erosion, as areas without protection of natural dunes, marine terraces, or sandstones (beach-rocks and ferruginous sandstones), areas with the presence of gullies and stretches where the sea-cliffs were in direct contact with the action of the sea, representing the beginning of the beach profile. In the morphodynamic study sought to carry out the survey of the physical and morphological characteristics, the analysis of sediment grain of the beaches and finally the analysis of the morphodynamic parameters to generate a table of risk to erosion by sector of the beach. The morphodynamic parameters were defined by the methodology proposed by Short (2006), in which considers different patterns of dynamism on beaches with characteristics favorable and unfavorable to erosive profiles. The maps indicated different levels of risk to the segments of the beaches analyzed, suggesting risk to erosion low and low to moderate only in areas north and northwest of the beaches of Madeiro and Curral, and levels of moderate and high risk sectors in the south and southeast of these beaches . The beach of Pipa showed moderate levels of risk and moderate to high at the ends and high risk to erosion in the central portion. The study of the coastal environment, its morphological evolution, and areas with problems of erosion, are of fundamental importance to assist coastal management policies, giving grants for planning activities undertaken in these regions
