Direct localized boundary-domain integro-differential formulations for physically nonlinear elasticity of inhomogeneous body [PDF]

open access: yes, 2005
A static mixed boundary value problem (BVP) of physically nonlinear elasticity for a continuously inhomogeneous body is considered. Using the two-operator Green-Betti formula and the fundamental solution of an auxiliary linear operator, a non-standard ...

Effect of Se-metal pair combinations (Cd, Zn, Cu, Pb) on photosynthetic pigmentsproduction and Metal accumulation in Sinapis alba L. seedlings

open access: yesPlant, Soil and Environment, 2006
The priority of this study was to investigate how selenium influences toxicity of Cd, Zn, Cu and Pb when the metals appear in the hydroponic solution in pairs. As a model subject mustard seedlings (Sinapis alba L.) were used.

Localized boundary-domain integral formulations for problems with variable coefficients [PDF]

open access: yes, 2002
Specially constructed localized parametrixes are used in this paper instead of a fundamental solution to reduce a boundary value problem with variable coefficients to a localized boundary-domain integral or integro-differential equation (LBDIE or LBDIDE).

Redox and biometal status in Wistar rats after subacute exposure to fluoride and selenium counter-effects

open access: yesArhiv za Higijenu Rada i Toksikologiju, 2022
This study aimed to investigate the effect of 150 mg/L sodium fluoride (NaF) on redox status parameters and essential metals [copper (Cu), iron (Fe), and zinc (Zn)] in the blood, liver, kidney, brain, and spleen of Wistar rats and to determine the ...

Determination of Valences of As, Cr, Sb and Se in Soil Using HPLC-HG-AFS

open access: yesYankuang ceshi, 2021
BACKGROUND The environmental effects of heavy metal pollutants in soil are closely related to their inorganic valence. The determination of the valences of As, Cr, Sb and Se elements is of great significance, but due to the easy conversion between the ...
