In the field of air quality control, optical remote sensing systems can measure the spatial distribution of gas pollutants, offering numerous advantages over conventional networks of in situ analysers. We propose some ...

Nannoplankton and foraminifera from the pelagic oozes from a water depth of 3 684 meters, 150 km southeast of Réunion Island, Indian Ocean, prove the NN18 and NN19 nannoplankton zones, indicating the Pliocene-Pleistocene ...

We present a novel technique to simulate numerically the measurements performed by a borehole induction-logging tool in 3D anisotropic rock formations. The simulations are based on an integral equation formulation. Previously, ...

From the late Cretaceous to the early Tertiary period, the Tethys seawater repeatedly invaded the Shaqa sub-basin and entered the Kuqa sub-basin through the Awati straight. At the same time, as a result of tectonic and ...

Electronic absorption spectra of the orthorhombic olivine-type phosphate minerals of the triphylite-lithiophilite series, M1[6]LiM2[6](Fex 2+ Mn1-x 2+)[PO4], were obtained on members with XFe = 0.195 (p, rs), 0.326 (sc, ...

The strong adsorption to kaolinite of four polyaromatic, cationic dyes (9-aminoacridine, 3,6-diaminoacridine, azure A and safranin O), which adsorb much less to alumina or silica, was investigated by means of acid-base ...

The sorption of Eu(III) onto kaolinite and montmorillonite was investigated up to 150 °C. The clays were purified samples, saturated with Na in the case of montmorillonite. Batch experiments were conducted at 25, 40, 80 ...

Macro- and molecular-scale knowledge of uranyl (U(VI)) partitioning reactions with soil/sediment mineral components is important in predicting U(VI) transport processes in the vadose zone and aquifers. In this study, U(VI) ...

Quaternary loess-soil sequences in China and Tajikistan are valuable archives of the chemical weathering history for arid and semi-arid regions of Asia. The development of new proxies independent of grain size are vital ...
