The paper is concerned with Lp error analysis of semi-discrete Galerkin FEMs for nonlinear parabolic equations. The classical energy approach relies heavily on the strong regularity assumption of the diffusion coefficient, which may not be satisfied in many physical applications. Here we focus our attention on a general nonlinear parabolic equation (or system) in a convex polygon or polyhedron ...

Through this study, the ability of a modified Peng-Robinson (MPR) equation of state in predicting the surface tension of n-alkanes based on the density functional theory approach was investigated and compared with other studies. The interfacial layer thickness and the density profile were calculated simultaneously at different temperatures from triple point to near critical point using the modi...

JANSEN, B. C. The toxic antigenic factors produced by Clostridium botulinum types C and D. Onderstepoort ]. vet Res., 38 (2), 93-98 (1971). The toxic factors produced by Clostridium botulinum (Van Ermengem, 1896), types C and D were determined. Monospecific antisera were prepared against the different factors. It was shown that type Coc produces factors C" C2 and D; type C f3 produces factor C ...

This paper develops a method to determine consistenly the integration of spatial integrity specifications, particularly for the case when two constraints, c1 and c2, are applied between three classes A, B, C (i.e., A c1 B and B c2 C), as such scenarios give rise to an implied consistency constraint c3 that holds between A and C. To determine c3, the mere composition reasoning with c1 and c2 is ...

In this work we suggest a simple mathematical model for the dynamics of the population of children and adolescents without problematic behavior (criminal activities etc.). This model represents a typical population growth equation but with time dependent (linearly decreasing) population growth coefficient. Given equation admits definition of the half-life time of the non-problematic children be...

C1 inhibitor of serine proteases (C1-INH) performs a regulatory function in the complement system and vascular permeability. Deficiency C1-INH leads to various forms angioedema, including hereditary angioedema (HAE). The cause HAE is genetically determined violation synthesis C1-INH. A decrease level 50% relative norm an increase production bradykinin, which basis for diagnosis HAE. development...

The c(s) method results in high-resolution sedimentation coefficient distributions by deconvoluting the effects of diffusion broadening. It is a direct model for sedimentation data covering the complete sedimentation process, based on finite element solutions of the Lamm equation, and algebraically accounts for the systematic noise structure encountered in transport experiments. A continuous se...

• Dictatorship: ( 1, . . . , n) = 1 • Democracy: When |C| = 2, c1 ( 1, . . . , n) c2 iff |{i : c1 i c2}| ≥ |{i : c2 i c1}|. Theorem 4.3. When |C| = 2, majority voting is the only social welfare functional that is monotone (an agent’s preference change from c1 to c2 does not cause the global preference to change from c2 to c1) and symmetric with respect to agents (permuting the agents does not c...

We provide necessary and sufficient conditions for the generalized ⋆Sylvester matrix equation, AXB+CX ⋆ D = E, to have exactly one solution for any right-hand side E. These conditions are given for arbitrary coefficient matrices A,B,C,D (either square or rectangular) and generalize existing results for the same equation with square coefficients. We also review the known results regarding the ex...
