1. VELHAS E NOVAS TERRITORIALIDADES NAS MARGENS DA BARRAGEM DE ANAGÉ- BA: da desterritorialização à reterritorialização. / OLD AND NEW DAM AT THE MARGINS TERRITORIALITY OF ANAGA-BA: deterritorialization of the repossession.
The barrages built in the Northeast would be linked to the politic of combat against drought and advantage of regional potentialities. In this context, the building of the barrage would offer support to the implantation of irrigation system, these were thought as alternative not only to solve the hydro problem, but also to make the agrarian system more dynam

2. Cultura materia e etinicidade dos povos indigenas do São Francisco afetados por barragens: um estudo de caso dos Tuxá de Rodelas, Bahia, Brasil
Há um capítulo vazio sobre a história e identidade dos grupos indígenas do São Francisco, hoje cerca de 32 povos, distribuídas em mais de 38 territórios. O Povoamento do Vale Arcaico Franciscano, segundo dados de pesquisas arqueológicas (VERGNE, 2004), teve início há pelo menos nove mil anos atrás. Contudo, entre a pré-história e história dos g

3. Fauna de Aedes (Ochlerotatus) scapularis e as alterações ambientais provocadas pela construção das barragens das usinas hidrelétricas Capim Branco I e Capim Branco II, no Rio Araguari, no Município de Uberlândia, Minas Gerais - Brasil
With the construction of two hydroelectric power plants in the lower level of Araguari river Capim Branco I and Capim Branco II , we had the opportunity to study the fauna of Ae. (Och.) scapularis in those areas, before and after the environmental alterations provoked by the construction. The study was carried out from May 2003 to April 2005, at the same tim

4. Efeitos do rompimento da Barragem de Camará na área urbana do Município de Alagoa Grande-PB.
In recent years an interminable succession of disasters has been witnessed, as floods, disruption of barrages, storms, earthquakes, landslides, volcanic eruptions, forest droughts and fires. These disasters have an extremely high price in lives, provoke ambient damages, many irreparable times, and imply in the investment of billions of dollar for repairing o

5. WATERS ACCUMULATED IN DAMS AND BARRAGES IN THE SANTA MARIA REGION AND FLUCTUATIONS IN ITS CHEMICAL PHYSICAL ATTRIBUTES. / ÁGUAS ACUMULADAS EM AÇUDES E BARRAGENS NA REGIÃO DE SANTA MARIA E FLUTUAÇÕES EM SEUS ATRIBUTOS FÍSICO QUÍMICOS.
A qualidade das águas superficiais de reservatórios depende da forma de uso do solo na bacia de contribuição de uso e ocupação do solo. Como a recarga se dá por deflúvio superficial o enriquecimento da água por nutrientes é conseqüência da forma de agricultura na bacia. Este trabalho teve como objetivo acompanhar as flutuações em propriedades f

6. Ãgua: recurso desencadeador de conflitos? os impactos sociais da construÃÃo da barragem pirapama
This work presents a quarrel on the current social movements as instrument of conquest and exercise of the citizenship. The small agricultural producers have so much time difficulties to keep the minimum conditions for its survival. The great projects and workmanships for the economic development with the construction of hidrelÃtricas and barrages for the w

7. Impactos ambientais associados a usina hidreletrica de Tres Irmãos : o fenomeno de ação e reação
Many environmental impacts were caused by the implantation of hydroelectric in Brazil among the decades of 50 and 80. In Sao Paulo State the great reservoirs add a superior area of 6.500Km2 of flooded areas, representing 2,6% of the surface of the State. The importance of that energy for the social and economical Brazilian s development is evident. However,

8. Mapas mensais de precipitação maxima e erosividade para o estado de São Paulo de interesse a engenharia
The objective of this work was to generate monthly maps of maximum intensity rains in 24 hours and of erosivity for the State of São Paulo, using monthly data of precipitation of maximum intensity of one day. The data of rain maximum in one day, of 343 were selected rain gage post of the State of São Paulo, operated by DAEE, with complete historical series

9. Amperometric detection of stimulus-induced quantal release of catecholamines from cultured superior cervical ganglion neurons.
Amperometry has been used for real-time electrochemical detection of the quantal release of catecholamines and indolamines from secretory granules in chromaffin and mast cells. Using improved-sensitivity carbon fiber electrodes, we now report the detection of quantal catecholamine release at the surface of somas of neonatal superior cervical ganglion neurons

10. Role of the ferret perigeniculate nucleus in the generation of synchronized oscillations in vitro.
1. The cellular mechanisms by which neurons of the ferret perigeniculate nucleus (PGN) participate in the generation of spindle waves and slowed absence seizure-like oscillations were investigated with intracellular and extracellular recording techniques in geniculate slices maintained in vitro. 2. During spindle wave generation, PGN neurons generated repeti

11. Impact of Persistent Cortical Activity (Up States) on Intracortical and Thalamocortical Synaptic Inputs
The neocortex generates short epochs of persistent activity called up states, which are associated with changes in cellular and network excitability. Using somatosensory thalamocortical slices, we studied the impact of persistent cortical activity during spontaneous up states on intrinsic cellular excitability (input resistance) and on excitatory synaptic in

12. Synaptic and membrane mechanisms underlying synchronized oscillations in the ferret lateral geniculate nucleus in vitro.
1. The cellular basis for generation of spindle waves and a slower synchronized oscillation resembling absence seizures was investigated with extracellular and intracellular recording techniques in slices of ferret dorsal lateral geniculate nucleus (LGNd) maintained in vitro. 2. Intracellular recording from LGNd relay cells in vitro revealed that spindle wav
