Ditadura militar, esquerda armada e memória social no Brasil
(Universidade Federal de São Carlos, 2011-05-18) Angelo, Vitor Amorim de; Villa, Marco Antonio; https://lattes.cnpq.br/4045059477271704
The thesis discusses the relationship between the Brazilian s military dictatorship and the armed left in the years 1960-70 and its effects on the social memory about that period. The preparation of the 1964 coup and the structuring of the military regime are often attributed to the National Security Doctrine (DSN), which would have be the rational basis of the action and the thought of the Brazilian military. From this point of view, build an efficient information-repressive apparatus would result by the DSN s guidelines. However, as the thesis demonstrates, the armed left never represented a real threat to the dictatorship. Using precisely the guerrillas as a justification for the intensification of the regime, part of the Armed Forces tried to impose on other military trends. Later, when the social memory about the military period began to be built, the armed left appeared as responsible for the end of the dictatorship, when we know that the regime was the one who gained strength in the combating of guerrillas. The establishment, consolidation and reproduction of this and other myths about the old left armed occurred during the amnesty mobilization, in the late of the 1970 s, and the Diretas Já!, in the next decade, when the former guerrillas have been in contact with several sectors society that opposed the dictatorship and fought for the return of democracy.
Caracterização de quatro espécies de quebra-pedra utilizando cromatografia líquida de alta eficiência hifenada a espectrometria de massa em múltiplos estágios
(Universidade Federal de São Carlos, 2011-05-18) Sprenger, Ricardo da Fontoura; Cass, Quezia Bezerra; https://lattes.cnpq.br/9197210255594409; https://lattes.cnpq.br/0974948816384258
This work presents the results of the use of High Performance Liquid Chromatography coupled to mass spectrometry in the chemical differentiation/characterization of aqueous extracts of plant samples of the genus Phyllanthus, commonly named as "stone braker". The species studied were P. amarus, P. stipulatus, P. niruri and P. tenellus. For medical purposes, the Brazilian Pharmacopoeia recognizes only P. niruri and P. tenellus. Samples of the plants used were grown and collected on the campus of Federal University of São Carlos (UFSCar). The goal of the work here reported was to compare the four species through the characterization of secondary metabolites. Structural characterization of secondary metabolites was achieved by interpretation of fragmentation data obtained in the online experiments of MS/MS and MS3using ion trap mass spectrometer equipped with an electrospray ionization source in positive and negative mode of ionization. Several chemical compounds were elucidated; some of them presents in all four species while others were found in a single species, this work presents and discusses the results. Furthermore two compounds from the species of P. stipulatus were isolated by semi-preparative liquid chromatography. These two isolated compounds were fully characterized by mass spectrometry and NMR, as corilagin and quercetin-3-O-β-D-glucuronopyranoside, an unusual flavonol in natural products
