Ground Penetrating Radar Attenuation Expressions in Shallow Groundwater Research
(Society of Exploration Geophysicists, 2020-03-01)
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 ...
Evaluation of water amount in hydrated ethanol fuel by gamma-ray attenuation technique
(2011-09-09)
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 ...

Critical coupling of surface plasmons in graphene attenuated total reflection geometry
(Elsevier Science, 2016-11)
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 ...
Resveratrol attenuates oxidative stress and muscle damage in sedentary rats subjected to physical exerciseResveratrol atenua o estresse oxidativo e a lesão muscular de ratos sedentários submetidos ao exercício físico
(2018-05-01)
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 ...
Acoustic fields of acid suspensions containing cassava bagasse: Influence of physical properties on acoustic attenuation
(2021-06-01)
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 ...
Modeling Forced Imbibition Processes and the Associated Seismic Attenuation in Heterogeneous Porous Rocks
(Blackwell Publishing, 2017-11)
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 ...
Attenuation mechanisms in fractured fluid-saturated porous rocks: a numerical modelling study
(Wiley Blackwell Publishing, Inc, 2019-05)
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 ...
