Landslides in tropical and sub-tropical regions are generally associated with weathered rock profiles which often possess chemical and mineralogical heterogeneities at materialand mineral-scales. Such heterogeneities reach a climax by the occurrences of oxyhydroxideand clayrich zones. Weakness and low permeability of these zones makes them ideal for the development of slip zones along which lan...

The mineralogical composition and typological classification of a group 226 Axe-God pendants from the Jade pre-Columbian Culture Museum (from Instituto Nacional de Seguros) in San José (Costa Rica) was studied, using non-invasive characterization technique novel stylistic scheme. Possible composition-design correlations were examined through descriptive functional statistical analysis. This stu...

this work aims to extract the mineralogical constituents of the lahroud hyperion scene situated in the nw of iran. like the other push-broom sensors, hyperion images suffer from spectral distortions, namely the smile effect. the corresponding spectral curvature is defined as an across-track wavelength shift from the nominal central wavelength, and alters the pixel spectra. the common “column me...

Interactions between injected CO2, brine, and rock during CO2 sequestration in deep saline aquifers alter their natural hydro-mechanical properties, affecting the safety, and efficiency of the sequestration process. This study aims to identify such interaction-induced mineralogical changes in aquifers, and in particular their impact on the reservoir rock's flow characteristics. Sandstone sample...

Due to their non-toxic nature, biodegradability and production from renewable resources, research has shown an increasing interest in the use of biosurfactants in a wide variety of applications. This paper reviews the characterization of rhamnolipid and sophorolipid biosurfactants based on their hydrophilicity/hydrophobicity and their ability to form microemulsions with a range of oils without ...
