In this paper mathematical techniques have been used for the solution of
Blasius differential equation. The method uses optimized artificial neural
networks approximation with Sequential Quadratic Programming algorithm and
hybrid AST-INP techniques. Numerical treatment of this problem reported in the
literature is based on Shooting and Finite Differences Method, while our mathematical
approach is very simple. Numerical testing showed that solutions obtained by using
the proposed methods are better in accuracy than those reported in literature.
Statistical analysis provided the convergence of the proposed model.
The investigation of complexation of uranium with biological
active ligands is vital for understanding uranium speciation in biosystems.
A number of studies have been undertaken for investigating the complexation of uranium
in its (VI) oxidation states but similar investigations pertaining to the interaction
of uranium, in lower oxidation states, with biological ligands is
scarce. The aim of the work is to bridge this gap and studies have been carried
out to determine the coordination pattern of pyridine-3-carboxylic acid with uranium(IV). Semi-micro analysis, spectro-analytical techniques,
magnetic susceptibility and cyclic voltammetry have been employed for the characterization
of the synthesized complex.
