Diário da Constituinte [gravação de vídeo] : [programa n. 546]

Enquanto não se decide a votação do capítulo da Reforma Agrária, já começam a se movimentar na Constituinte os grupos de pressão para o próximo Título a ser votado: o da Ordem Social. Exposição em defesa do Sistema Único de Saúde está na rampa de acesso ao Plenário. Um vídeo apresenta depoimentos dos defensores do Sistema Único. Também chegaram à Constituintes 143.000 assinaturas populares, recolhidas no Rio de Janeiro, em defesa da Escola Gratuita. Constituintes, diante do abaixo assinado, ressaltam a importância de destinar recursos públicos para a escola pública, além das escolas comunitárias, confessionais e as filantrópicas, sem fins lucrativos. A Reforma Agrária também tem seu lobby. Ele está montado no corredor de acesso ao Plenário. São painéis mostrando a história das lutas no campo. Líderes partidários e os representantes do Centrão,se reúnem no Gabinete do Senador Mário Covas para discutir a Reforma Agrária. O impasse permanece quanto à definição da terra produtiva e quanto à necessidade de cumprir ou não a função social.

La crisis de la garantía hipotecaria en las corporaciones de ahorro y vivienda, la crisis del UPAC y estudios sobre la ley 546 de 1999

El tema de la vivienda en los últimos años, con sus múltiples componentes, comenzando por el UPAC, se convirtió en la pesadilla más tormentosa para los colombianos, sin importar su condición social: muchos empresarios quebraron en la construcción

Nocturnal periodic breathing during acclimatization at very high altitude at Mount Muztagh Ata (7,546 m)

Quantitative data on ventilation during acclimatization at very high altitude are scant. Therefore, we monitored nocturnal ventilation and oxygen saturation in mountaineers ascending Mt. Muztagh Ata (7,546 m).

Stable chlorine isotopes in pore waters from DSDP Hole 79-546 and ODP Hole 131-808C

Stable Cl isotope ratios, measured in marine pore waters associated with the Barbados and Nankai subduction zones, extend significantly (to ~-8 per mil) the range of d37Cl values reported for natural waters. These relatively large negative values, together with geologic and chemical evidence from Barbados and Nankai and recent laboratory data showing that hydrous silicate minerals (i.e., those with structural OH sites) are enriched up to 7.5 per mil in 37Cl relative to seawater, strongly suggest that the isotopic composition of Cl in pore waters from subduction zones reflects diagenetic and metamorphic dehydration and transformation reactions. These reactions involve clays and/or other hydrous silicate phases at depth in the fluid source regions. Chlorine therefore cannot be considered geochemically conservative in these systems. The uptake of Cl by hydrous phases provides a mechanism by which Cl can be cycled into the mantle through subduction zones. Thus, stable Cl isotopes should help in determining the extent to which Cl and companion excess volatiles like H2O and CO2 cycle between the crust and mantle.

Geochemistry and isotopes at DSDP Hole 79-546

At Site 546, below the Mazagan Escarpment at a water depth of 4 km, 36 m of salt rock was cored from the top of one of a field of salt domes. The core was studied by thin section and a variety of geochemical procedures. The salt rock contains 0.1 to 3% carnallite and lesser amounts of sylvite and polyhalite, which with the corresponding high level of bromide place it within the potash evaporite facies. The bromide profile is of a dominantly marine evaporite deposited in moderately shallow brine which, however, was not repeatedly desiccated. A mineralogical argument suggests that the brine surface was not below sea level. An average of about 5% elastics, with dispersed anhydrite, darken the salt rock to deep shades of red, brown, and gray green. Most of the included materials are in highly deformed boudins or dispersions in the salt rock that has also undergone cataclasis in a subsequent, probably tectonic, deformation. The salt rock is slightly deficient in anhydrite, and the usual separate beds and laminae of anhydrite are virtually absent. Stable isotope ratios of sulfur and oxygen in the sulfate are clearly derived from sea water of Permian to Scythian age, in contrast to the late Triassic or Early Jurassic age of evaporites onshore in Morocco and Portugal and the corresponding evaporites offshore Maritime Canada. In contrast to those evaporites off the axis of Atlantic rifting, the salt at Site 546 may have been deposited in a very early central rift fed by marine waters from Tethys through the Gibraltar or South Atlas fracture zones.
