This extensive thesis work covers several topics, including intensity and polarization, focusing on a new polarization bias reduction method. Vidal studied data from the WMAP satellite, which is low signal-to-noise and as such has to be corrected for polarization bias. He presents a new method for correcting the data, based on knowledge of the underlying angle of polarization. Using this novel method, he sets upper limits for the polarization fraction of regions known to emit significant amounts of spinning dust emissions. He also studies the large-scale loops and filaments that dominate the synchrotron sky. The dominant features are investigated, including identification of several new features. For the North Polar Spur, a model of an expanding shell in the vicinity of the Sun is tested, which appears to fit the data. Implications for CMB polarization surveys are also discussed. In addition, Vidal presents interferometric observations of the dark cloud LDN 1780 at 31 GHz and shows that the spinning dust hypothesis can explain the radio properties observed.
Essa é a versão original, escrita por Francisco de Andrade Barroso (Valmir) e reeditada por mim Orlando Andrade, como forma de manter viva a chama da família Andrade e a memória de Valmir. Nele encontrarás a história dessa família e sua genealogia, bem como de muitas outras famílias históricas do Ceará (Limas, Bonfins, Correias, Pinheiros, Pereiras, etc.).
This Element analyses the political dynamics of neo-extractivism in Latin America. It discusses the critical concepts of neo-extractivism and the commodity consensus and the various phases of socio-environmental conflict, proposing an eco-territorial approach that uncovers the escalation of extractive violence. It also presents horizontal concepts and debates theories that explore the language of Latin American socio-environmental movements, such as Buen Vivir and Derechos de la Naturaleza. In concluding, it proposes an explanation for the end of the progressive era, analyzing its ambiguities and limitations in the dawn of a new political cycle marked by the strengthening of the political rights.
'NDiaye is a hypnotic storyteller with an unflinching understanding of the rock-bottom reality of most people's life.' New York Times ' One of France's most exciting prose stylists.' The Guardian. Obsessed by her encounters with the mysterious green women, and haunted by the Garonne River, a nameless narrator seeks them out in La Roele, Paris, Marseille, and Ouagadougou. Each encounter reveals different aspects of the women; real or imagined, dead or alive, seductive or suicidal, driving the narrator deeper into her obsession, in this unsettling exploration of identity, memory and paranoia. Self Portrait in Green is the multi-prize winning, Marie NDiaye's brilliant subversion of the memoir. Written in diary entries, with lyrical prose and dreamlike imagery, we start with and return to the river, which mirrors the narrative by posing more questions than it answers.
