Autores: VALDIVIESO SALAZAR, C. R.; CORDEIRO, G. G.
Mais de 16.000 pocos ja foram perfurados nas rochas igneas metamorficas do embasamento cristalino do Semi-Arido do Nordeste do Brasil, segundo levantamento de 1983. Os aquiferos nestas formacoes sao constituidos por fraturas e fendas da rocha, cujas caracteristicas hidrogeologicas se desconhecem. Caracteristicas de vazoes esses pocos e qualidade das aguas tem marginalizado a utilizacao racional desse recurso. Assim, tem-se vazoes que variam entre 0,0 a mais de 16.000 l/h e pode-se dizer que, em geral, as aguas sao mineralizadas em maior ou menor grau, com teores de residuo seco variando entre 1 a 10 g/l. O objetivo deste trabalho e, pois, apresentar as alternativas e possibilidades de uso destas aguas subterraneas do embasamento cristalino na regiao, ainda...

Autores: Fall, M.
La présente campagne en mer du N/O ITAF DEME constitue la 3 ième partie de l'activité d'évaluation de la biomasse en saison froide, des ressources démersales cîtères du Sénégal. Du fait de certains contraintes (réparation du bourrelet du chalut, fêtes religieuses, vote pour certains marins,etc.) elle a été programmée sur 05 jours (24-28 avril 2001). Suite logique de la mission qui l'a précédé cette sortie vise, pour l'essentiel à complèter d'abord la visite des stations restantes de la radiale X, puis à assurer celle des radiales XI et XII en zone centre. Soit un total théorique de 32 traits de chalut à réaliser.

The eastern Africa flamingo Lakes: Building partnerships for sustainable resource management
Provedor de dados: 20
Autores: Raini, Jackson A.
The saline alkaline lakes of the Eastern Africa Rift Valley 'Flamingo Lakes' support diverse biological resources that are of global, regional, national and local importance. These lakes form the center piece of some of the world renowned national parks and conservation areas and are major feeding, staging and displaying ground for the region's Lesser flamingo (Phoeniconaias minor), Greater flamingo (Phoenicopterus ruber) and for over 70 species of water birds. Unsustainable land use practices within the basins of these lakes during the last four decades have adversely affected the environment in many ways. Notable among the effects are the diminishing forested areas, rampant soil erosion, waste disposal problems and deterioration in catchment water...

ABSTRACT The study of cultivars with moderate flood tolerance is essential to their use in pastures irrigated with saline water. The aim of this study was to evaluate the chemical composition of Panicum maximum ‘BRS Zuri’ under the effect of different irrigation depths and levels of salinity. A randomised block design of split plots was used with five replications per treatment. The treatments resulted from the combination of three levels of water salinity (S1 = 0.6, S2 = 1.8 and S3 = 3.0 dS m-1) and four levels of irrigation (I1 = 60%, I2 = 80%, I3 = 100% and I4 = 120% of the evapotranspiration). The chemical composition of the grass, Panicum maximum ‘BRS Zuri’, cut at 28 days, was evaluated over two cycles. There was an interaction between the factors...

Sarcocornia ambigua (Michx.) M.A. Alonso &amp;amp; M.B. Crespo is the most widely distributed species of the perennial genus of glasswort in South America, and it shows great biotechnological potential as a salt-water irrigated crop. Qualitative and quantitative compositions of fatty acids were determined in the seeds of S. ambigua that were cultivated in southern Brazil. Hexane extraction of the seed oil from S. ambigua yielded 13% of total lipids. The GC-FID (Gas Chromatography Flame Ionization Detector) analysis of the hexane extracts showed five prominent peaks for the seed oil: 42.9 wt.% linoleic-Ω6 acid (18:2), 20.4 wt.% palmitic acid (16:0), 18.5 wt.% oleic acid (18:1), 4.5 wt.% stearic acid (18:0) and 4.0 wt.% linolenic-Ω3 acid (18:3). The sum of...
