High waterborne Mg does not attenuate the toxic effects of Fe, Mn, and Ba on Na+ regulation of Amazonian armored catfish tamoatá (Hoplosternum litoralle)
(2018-06-01)
Formation water (FoW) is a by-product from oil and gas production and usually has high concentrations of soluble salts and metals. Calcium (Ca) and magnesium (Mg) have been shown to reduce the toxicity of metals to aquatic ...
Hydrogen uptake and diffusivity in steel armor wires with different chemical composition, carbide distribution, grain size, and degree of deformation
(Wiley VCH Verlag, 2022-03)
In this study, six flexible pipe steel armor wires used in oil and gas transportation are characterized, and their hydrogen diffusion coefficients and hydrogen uptakes are measured using an electrochemical hydrogen permeation ...
Impact of glyphosate formulations and adjuvants: effects on leaf interaction, metabolism, and control of sourgrass
(Univ Federal Santa Maria, 2022-01-01)
The addition of commercial formulations and adjuvants to a tank mix may result in differences in the wettability on the plant surface, foliar uptake and herbicide efficacy. Thus, the objectives of this study were to evaluate ...
Use of montmorillonite to recover carboxylic acids from aqueous medium
(Elsevier Science, 2019-12-15)
In this work, it was investigated the use of montmorillonite as a trap to recover small carboxylic acids from aqueous medium. TOC and titration analyses showed remarkable uptake of organic acid molecules, e.g. 46, 49, 9 ...
