Vladimir I. Arnoldy, welfare is now legally enforceable and demandable with a well worked out legal system (targeted goals versus due focus on elaborately worked out means and processes), focusing on equity, non-discrimination, transparency, accountability and participation (core of rights-based development). Hence,

Vladimir I. Arnoldt in a standard experiment for each ligand of interest using a moderately stirred (100-200 rpm) cell and analysis of the mixture produced on the OUT side of the cell at a fixed, small extent of transport. Together with duplicates and controls, this modest set of experiments will place the results on

The General Theory for One First-Order Equation,while others have no theory at all. The reason for this complexity is a more complicated geometry. In the case of an ordinary differential equation a locally integrable vector field (that is, one having integral curves) is defined on a manifold. For a partial differential equation a subspace of the

The General Theory for One First-Order Equation (Continued),The equation determines a 2.-dimensional hypersurface .. in the space .. of 1-jets of functions of (..,... ,..). Each function has a 1-graph in ..; it is a solution of the equation if its 1-graph is a submanifold in ...
