as a by-product into the solution according to these reactions. CuFeS2+2H+=CuS2+H2S+Fe2+=-2.303×8.314×298lg{[Fe2+][H2S]/[H+]2}=20421 J/mol (3) 2CuFeS2+4H+=CuS2+2H2S+S+Fe2+=-2.303×8.314×298lg{[Fe2+]2[H2S]2/[H..., thiosulphate and elemental sulphur mechanisms) for the mixed chalcopyrite-chalcocite ore. (3) The speciation turns into Cu2S-CuS-Cu5FeS4- Cu2S before turning into CuSO4 since the final product requires......
is to find two matrices W and H, and the factorization condition is M≈XTWTHY. As shown in Figure 3, our approach is to factorize the matrix M into the product form of matrices W and H; matrices X and Y......
using L2 norm to measure similarity between matrices; x represents the original gait silhouettes; Ma represents a binary mask matrix; Θ denotes the Hadamard product of the matrix Ma and the corresponding......
for detection angles of: If the detection angle and range are set to 50° and 200 m, respectively, not only is the highest collision-avoidance performance obtained but also the product cost seems to be reasonable......
, 32]. And, in the process of synergistic catalysis, levulinic acid was often accompanied as a by-product due to the tendency of HMF to undergo further rehydration reaction[33, 34]. However... started. After the reaction was over, the mixture was cooled to room temperature. The liquid was filtered before further analysis using HPLC. C Product analysis The concentration of HMF......
test. It can be concluded that ions content changes of CGN-(F+S)-4 and CGN-(F+S)-5 are gained mainly due to the solution used in this research. The variation of Ca2+ content could reflect the product......
of the product, process and system with a significant slash in experimental time and cost [20]. Three categories of quality characteristics are defined in the signal/noise analysis (S/N ratio), i.e.......
, 18(10): 307-312. DOI: 10.1002/jctb.5010181005. [5] KOSTIC-PULEK A, MARINKOVIC S, POPOV S, DJURICIC M, DJINOVIC J. The treatment of gypsum as a product of the flue gas desulphurization process [J......
, the mass flow rate of the working fluid in the ORC system is reduced, but its specific enthalpy drop is increased. Therefore, when the evaporation temperature is 76 °C, the product of the two parameters......
of heavy rare earth elements (HREE), and presence of the aluminum-rich minerals muscovite and garnet as proposed by BARBARIN [44], is a partially melted product of thickened continental crust......
