Quality indices of groundwater for agricultural use in the Soconusco, Chiapas, Mexico
(2017)"In Soconusco, Chiapas, in spite of the high availability of surface water, it is resorting to the use of groundwater. Knowledge about the quality of surface or groundwater used to irrigate crops in that region is low. ... -
Reappraisal of Los Humeros Volcanic Complex by New U/Th Zircon and 40Ar/39Ar Dating: Implications for Greater Geothermal Potential
(American Geophysical Union, 2018)"Longevity and size of magmatic systems are fundamental factors for assessing the potential of a geothermal field. At Los Humeros volcanic complex (LHVC), the first caldera-forming event was reported at 46040 ka. New zircon ... -
Recent advances in understanding the terminal Ediacaran Earth-life system in South China and Arctic Siberia
(CSIC, 2019)"The terminal Ediacaran contains dramatic changes in biogeochemical cycles, many of which are closely coupled with evolutionary transitions in the corresponding fossil records. Dynamic redox conditions may have caused a ... -
Removal of Cu, Cd, Pb and Zn from Contaminated Soil by Using Plant-Based Surfactants, Sapindus mukorossi L (Soapnut) and Acacia Concinna (Shikakai)
(IJESD, 2019)"The performance of two plant-based surfactants in the removal of heavy metals (Cu, Cd, Pb and Zn) from soil was studied ex-situ. Experimental parameters were: six soil-solution ratios (1:10, 1:20, 1:30, 1:40, 1:50 and ... -
Respuesta hidrológica en zonas urbanas ante eventos severos de tormenta aplicando modelación numérica e información SAR: Caso Los Mochis
(2019-12-13)"En años recientes, las inundaciones se han convertido en el fenómeno natural con mayor afectación a nivel mundial provocando severas pérdidas económicas. En el caso de México debido a sus características fisiográficas ... -
Riesgo por emisiones de radón en el área metropolitana de San Luis Potosí
(2015-10)"El radón (222Rn), es un gas radiactivo de origen natural, el cual aporta la mayor parte de la radiación que recibe el ser humano a lo largo de su vida; el radón no tiene olor, color ni sabor, por lo que la forma de ... -
Rock magnetism and microscopy of the Jacupiranga alkaline-carbonatitic complex, southern Brazil
(Springer, 2009)"This study of the Cajati deposit provides evidence that the ore was neither purely hydrothermal, nor volcanic in origin, as previous workers have proposed. The ores were formed from magnetite-rich magmas, hydrothermally ... -
Role of unsaturated soil above a heavily contaminated aquifer in the natural attenuation of arsenic
(EDP Sciences, 2019)"Large attenuation of arsenic is observed in a shallow aquifer in central Mexico, where the concentration decreases from 91.5 to 11.3 mg/L, over 1.3 km horizontal distance. To investigate possible mechanisms of attenuation ... -
Sand waves generation: a numerical investigation of the Infiernillo Channel in the Gulf of California
