abstract in the present research solution of chalcopyrite in sulfuric acid in hydrometallurgy method using electrochemistry with cyclic voltammetry technique has been investigated. the value of maximum reduction peak current of copper ions represents the measure of solubility. in this research different parameters temperature, potential, potential exert time, chalcopyrite concentration, sulfur...
Background: The "executive functions" as higher-level cortical functions with the supervisory and controlling role on the lower-level cognitive functions lead to human adaptive behaviors in the specific situations. These situations occur in the conditions in which automatic behavior may be insufficient. Executive function deficits in children may be presented with poor memory, problem-sol...
an infinitely long hollow cylinder containing isotropic linear elastic material is considered under the effect of arbitrary boundary stress and thermal condition. the two-dimensional coupled thermoelastodynamic pdes are specified based on equations of motion and energy equation, which are uncoupled using nowacki potential functions. the laplace integral transform and bessel-fourier series are u...
some new water-soluble schiff base complexes of na2[m(5-so3-1,2-salophen)].nh2o; (5-so3-1,2-salophen = n,n’-bis(5-sulphosalicyliden)-1,2-phenylendiamine); na2[m(5-so3-2,3-salpyr)(h2o)n].2h2o; (5-so3-2,3-salpyr = n,n’-bis(5-sulphosalicyliden)-2,3-diaminopyridine); and na2[m(5-so3-3,4-salbenz)(h2o)n].nh2o; (5-so3-3,4-salbenz = n,n’-bis(5-sulphosalicyliden)-3,4-diaminobenzophenon); where m = cu, n...
Abstract This paper presents several properties and relations that satisfy the components of a bicomplex holomorphic function. It also exhibits analogies differences with case analytic functions.
In this study, inverse nodal problem is solved for the p-Laplacian operator with two potential functions. We present some asymptotic formulas which have been proved in [17,18] for the eigenvalues, nodal points and nodal lengths, provided that a potential function is unknown. Then, using the nodal points we reconstruct the potential function and its derivatives. We also introduce a solution of i...
complicated potential structure formed at a constriction of positive column of a dc discharge with heated cathode in he at low discharge currents is investigated. according to the potential structure, electrons and ions are accelerated by the electric field and their energy distribution functions acquire multi humped shapes. additional maximums on distribution functions quickly disappear due to...
Strategic programming, Complex supply chain, Lean, Production programming, Suppliers selection, ELECTRE This paper represents a model of strategic programming with limited resources in a complex supply chain. The main goal of the proposed model is to increase efficiency and effectiveness of the supply chain with respect to income increases and cost decreases. Using special objective funct...
