Benthic macroinvertebrates of a tropical lake: Lake Caçó, MA, Brazil.
Benthic communities are highly relevant in the study of aquatic ecosystems, both for their role in the functioning of the ecosystem and also as markers or indicators of paleo-conditions. Their distribution, as in other communities, is conditioned by abiotic and biotic factors and to their interactions, which determine the structure of the community that is established. The aim of this study was...
متن کاملComposition Variation of Illite-vermiculite- Smectite Mixed-layer Minerals in a Bentonite Bed from Charente (france)
Mineralogical and chemical variations were studied in the upper half of a 1 m thick discontinuous bentonite bed interlaminated in the Lower Cenomanian sedimentary formations of the northern Aquitaine basin (France). X-ray diffraction patterns obtained from the <2 μm fraction in the Ca and K-saturated states were decomposed and compared to those calculated from decomposition parameters. They rev...
متن کاملConcentration of Dioctahedral Mica and Vermiculite Using a Fluoride Solution
A SOT.U~ON containing fluoride (0.4 N NH4F, 0.1 br HC1, ~ NH4C1), pcrmi~ the concentration of dioctahedral mica end dioctahedral vermiculite in mixed clay systems. AUophane, haUoysite, kaolinite, and in particular, Mg-rich montmorfllonite, biotite, and vermiculite of clay size, are destroyed in 24-48 hr at room temperature. A salt-free, NH4-saturated sample, weighing 80 mg, is shaken in 80 ml o...
متن کاملNumerical Simulation of Fecal Coliform Dynamics in Luruaco Lake, Colombia
The Luruaco Lake located in the Department of Atlántico, Colombia, is damaged by the discharge of untreated sewage, bringing risks to the health of all who use its waters. The present study aims to perform the numerical simulation of the concentration dynamics of fecal coliforms in the lake. The simulation of the hydrodynamic flow is carried out by means of a two-dimensional horizontal (2DH) mo...
متن کاملAnalogue modeling of instabilities in crater lake hydrothermal systems
We carried out analogue experiments on two-phase boiling systems, using a porous vertical cylinder, saturated with water. The base of the cylinder was heated, and the top was cooled, as in a natural hydrothermal system. Previous work had shown that once the two-phase zone reached a certain level, thermal instabilities would develop. We made measurements of the acoustic energy related to boiling...
