AI Technical Summary

Technical Problem

Current technologies face challenges in efficiently and cost-effectively removing elemental mercury (Hg0) from flue gas and oxidized mercury (Hg2+) from waste liquid, particularly due to the limitations of activated carbon injection which is affected by NOx and SO2.

Method used

The use of metal sulfides, such as FeS2 and CuS, as adsorbents that contact flue gas and waste liquid to adsorb and convert Hg0 and Hg2+ into stable mercury sulfide compounds.

Benefits of technology

This approach enables efficient, cost-effective, and environmentally friendly simultaneous removal of Hg0 from flue gas and Hg2+ from waste liquid, avoiding secondary pollution and reducing operational costs.

Abstract

The invention relates to a method for determining an item of data representative of an internal muscle load (CM) exerted by least one muscle belonging to a muscle group. The method comprises the steps of: - obtaining (A10) items of kinematic data (i(t)) and electromyographic data (emg(t)) collected during a contraction of the at least one muscle; - determining (A20) a muscle-tendon length (lMT(t)); - determining (a30) a muscle activation level (a(t)); - determining (A40) a muscle length (lM(t)) and a contraction speed (vM(t)); - determining (A50) an estimate of a muscle deformation (dM(t)); - calculating (A60) a muscle stress index (sM(t)); and - calculating (A70) the internal muscle load (CM) by the product of the muscle stress index (sM(t)) and the duration (t) of the effort.
