The volume properties of reverse micellar systems bis(2-ethylhexyl) sulfosuccinate sodium salt/n-heptane/dimethyl sulfoxide-water are studied via densitometry. The presence of dimethyl sulfoxide and the increase in its amount in a dimethyl sulfoxide-water mixed solvent raise the apparent volume of the polar phase. This increase is also observed when the degree of hydration of the polar core and the temperature are raised. 相似文献

The regiochemistry of the reaction of 1,2- and 1-substituted derivatives of 1-buten-3-yne and its 4- and 2,4-substituted derivatives of the isoprenoid type with acetoacetic ester and acetylacetone in the presence of the manganese(III) acetate-copper(II) acetate oxidative system was studied. Derivatives of 4,5-dihydrofuran, furan, and hexahydrobenzofuran were obtained.Communication 137 from the series Reactions of unsaturated compounds.

The paper establishes that there exist a continuum cardinality set E 0 ? [0, 1] and a function f 0(x) ∈ C [0,1], such that the greedy algorithm of f 0(x) with respect to the Faber-Schauder system converges to +∞ at all points of E 0. 相似文献

We derive quantum diffusion equations with transport coefficients explicitly depending on time from generalized non-Markovian
Langevin equations and obtain generalized fluctuation-dissipation relations. We substantiate the axiomatic Lindblad approach
in the microscopic model. For non-Markovian dynamics, we find sets of diffusion coefficients that ensure the purity of states
at any instant.

The paper uses the asymptotically justified hypothesis method to construct three different general refined theories of micropolar
thin elastic plates, depending on the values of physical dimensionless material parameters, involving: (i) independent displacement
and rotation fields, (ii) constrained rotation, and (iii) low shear stiffness. All angular shear deformations are taken into
account. 相似文献
