3. Estudo da atividade citotóxica do poliacetileno 5-octa-2, 4, 6-triinil-furan-2(5H)-ona / Study of the cytotoxic activity of polyacetylene 5-octa-2,4,6-triinil-furan-2 (5H)-one
Skin cancers are the most common types of cancer in Brazil, and correspond to around 25% of all malignant tumors recorded. Of these, melanoma represents at least 5% and is characterized by its high metastatic power. The development of anticancer agents from natural products is considered critical to pharmacology, and interest in the development of more effec

5. Characterization of the photosynthetic conditions and pigment profiles of the colour strains of Hypnea musciformis from field-collected and in vitro cultured samples
Hypnea musciformis (Wulfen) JV Lamour. is a species of great economic interest as it produces Κ-carrageenan and has shown biological activities against HIV and HSV viruses. This species displays different colour strains in its natural habitat, which may have implications for the biotechnological potential of the species. The aim of this study was to charact

7. Convenções financeiras e a taxa básica de juros no Brasil / Financial conventions and Brazilian basic interest rate
Este trabalho trata primeiramente, de um ponto de vista teórico, da existência de convenções nos mercados de ações e títulos de dívida. Serve de ponto de partida a noção, presente em Keynes, de que convenções envolvem técnicas para lidar com a incerteza, quando não há uma distribuição de probabilidades bem definida e confiável sobre o futur

8. Comportamento sexual de cabras Toggenburg durante a estação reprodutiva após luteólise natural ou induzida
Proestrus (days -2 and -1), estrus (days 1, 2 and 3) and metaestrus (days +1 and +2) sexual behavior was monitored in Toggenburg females goats, during natural breeding season after induced and natural luteolysis. The females received two doses of PGF2 10-day interval, for estrus synchronization. After the first injection the estrus was monitored three times

O ÍNDICE DE SUSTENTABILIDADE AMBIENTAL DO USO DA ÁGUA (ISA) COMO FERRAMENTA DE CONTRIBUIÇÃO ÀS POLITICAS PÚBLICAS DE DESENVOLVIMENTO E CONSERVAÇÃO NA BACIA DO RIO BACANGA, SÃO LUÍS/ MA. / INDEX FOR ENVIRONMENTAL SUSTAINABILITY OF WATER USE (ISA) AS A TOOL FOR CONTRIBUTION TO THE POLICIES PUBLIC DEVELOPMENT AND CONSERVATION IN BACANGA RIVER BASIN, SÃO LUIS / MA.
A hydrographic basin is a complex environmental system, resulting from the interrelations between the physical-natural and socioeconomic subsystems. Its identity as the unifying of environmental processes and human interference is leading to its adoption as a research unit. It allows from the analysis of the physical-chemical, biological and socioeconomic fa

11. The natural rate of interest in Brazil between 1999 and 2005
O objetivo desse estudo é estimar o nível da taxa natural de juros para o Brasil. Inicialmente filtros estatísticos são usados nas séries de taxas de juros reais ex-post e ex-ante. Depois disso, estima-se uma regra de Taylor dinâmica. Os resultados desses dois experimentos são comparados com a taxa natural de juros que é estimada a partir de um model
