Large volume of evaporites were deposited during the Messinian Salinity Crisis (MSC) across Mediterranean. These are currently outcropping on land and interpreted by seismic profiles beneath Mediterranean floor. Biostratigraphic, magnetostratigraphic astrochronologic data recovered from sediments below above evaporites, together with gypsum facies associations stratigraphic cyclicity, cornersto...

OBJECTIVE to evaluate changes in the expression of tumor necrosis factor-α in patients with rheumatoid arthritis submitted to phototherapy. MATERIALS AND METHODS This was an open label study, enrolling ten patients. The phototherapy scheme within a range of 425 to 650 nm, 11.33 Joules/cm2, 30 cm above the chest was as follows: a) 45-min daily sessions from Monday to Friday for 2 to 3 months; ...

On the mid-Norwegian margin, extensive rifting and subsequent deposition of thick Cretaceous Cenozoic sediments have buried traditional Upper Jurassic organic-rich shales too deep. Consequently, these are overmature spent in deep basins on margin. The absence well-control, variable seismic quality particularly, great burial depth, makes it difficult to identify alternative Lower units. By combi...

In the present research, the aqueous suspensions of nano-sized YSZ particles were prepared using a common and available dispersant (Dolapix CE64) at different pH values and their stability were evaluated through the sedimentation height, viscosity measurement, and microstructural observation. Different amounts of dispersant were tested and the optimum percentage was examined by measuring the vi...

Abstract. The process of continuous sedimentation of particles in a liquid has often been predicted by means of operating charts and mass-balance considerations, where the underlying constitutive assumption is the one by Kynch. Much more complex operating charts (concentration-flux diagrams) can be obtained from a onedimensional model of an ideal continuous clarifier-thickener unit. The enginee...

From the rupture of Fundão dam in Mariana–MG, there are tailings still present at bottom plant that must be recovered. The flocculation followed by sedimentation operation can applied as a unit this recovering process. Instead using conventional inorganic coagulants, bio-based coagulants offer some advantages, due to their low toxicity and biodegradability. Nonetheless, use mining industry is n...
