Non-asymptotic lazer-leach type conditions for a nonlinear oscillator
(American Institute of Mathematical Sciences, 2011-03)
A well-known result by Lazer and Leach establishes that if g: R → R is continuous and bounded with limits at infinity and m ε2 ℕ, then the resonant periodic problem u" + m2u + g(u) = p(t), u(0)-u(2π) = u'(0)-u'(2π) = 0 ...
Production of agroindustrial ashes with pozzolanic activity via acid leaching, conjugated burning and ultrafine grinding
(ANTAC - Associação Nacional de Tecnologia do Ambiente Construído, 2020)
Extruded fish feed with high residual phytase activity and low mineral leaching increased P. mesopotamicus mineral retention
(Elsevier Science, 2018-06)
This study attempts to provide valuable information about optimization of extrusion process in order to have a fish feed with maximum residual phytase activity, minimum mineral leaching and good mechanical characteristics. ...
Multivariate factorial analysis to design a robust batch leaching test to assess the volcanic ash geochemical hazard
(Elsevier Science, 2012-04-07)
A method to obtain robust information on short term leaching behaviour of volcanic ashes has been developed independently on the sample age. A mixed factorial design (MFD) was employed as a multivariate strategy for the ...
Atrazine behavior in an agricultural soil: adsorption–desorption, leaching, and bioaugmentation with Arthrobacter sp. strain AAC22
(Springer Heidelberg, 2022-01)
Purpose: To evaluate atrazine behavior in an agricultural soil (adsorption–desorption, leaching) and the effects of bioaugmentation with the Arthrobacter sp. strain AAC22, as a soil remediating strategy. Material and ...
Leaching of Atrazine, Ametryne and Prometryne in the SoilTítulo en español.

Soil properties of sugarcane fields controlling triazine leaching potential.
(CSIRO PUBLISHING, 2019-08-21)
Atrazine and ametryn are pre- and post-emergence herbicides widely used in sugarcane fields. Both herbicides are characterized by their moderate to high mobility in soil and are regarded as a threat to hydrologic systems. ...
