The electromagnetic-wave attenuation coefficient determines the overall resolution and effective penetration depth of ground penetrating radar (GPR) surveys. Despite this relevance to the design of proper GPR surveys, the ...

In this work, is presented an alternative and non conventional technique for evaluate the water amount present in the hydrated ethanol used as automotive fuel. The standard technique used in this kind of measure is the use ...

We study the optical response of an attenuated total reflection (ATR) structure in Otto configuration with graphene sheet, payingespecial attention to the occurrence of total absorption. Our results show that due to ...

Physical inactivity is a public health problem when a sedentary population practices physical activity sporadically. Exercise in unconditioned individuals causes oxidative stress and muscle damage. This study tested the ...

The effects produced by high-intensity ultrasound application during the acid pretreatment of biomass can enhance its later conversion into bioethanol. Therefore, it is interesting to evaluate how residues, such as cassava ...

Quantifying seismic attenuation during laboratory imbibition experiments can provide useful information toward the use of seismic waves for monitoring injection and extraction of fluids in the Earth's crust. However, a ...

Seismic attenuation mechanisms receive increasing attention for the characterization of fractured formations because of their inherent sensitivity to the hydraulic and elastic properties of the probed media. Attenuation ...
