Quantum social networks
(IOP Science, 2012)
We introduce a physical approach to social networks (SNs) in which each actor is characterized by a yes–no test on a physical system. This allows us to consider SNs beyond those originated by interactions based on ...

Characterization of source rocks and groundwater radioactivity at the Chihuahua valley
(Sociedad Mexicana de Física, 2007)
As part of a scientific research project about alpha radioactivity in groundwater for human consumption at the Chihuahua City, the charac-terization of rock sources of radioactivity around de Chihuahua valley was developed. ...

Occupational, public and environmental radiological impact caused by the phosphoric acid industry: the case of Huelva (Spain)
(Intech, 2017)
The production of phosphate fertilizers usually uses as raw material sedimentary phosphate rock, which contains enhanced concentrations from U‐series radionuclides about 10–100 times higher than unperturbed soils. ...
