10 Quantification of electroinactive dopants in conductive polypyrrole (PPY) films was performed with electrochemistry combined on-line with inductively coupled plasma-atomic emission spectrometry (EC/ICP-AES). Anion (HSO4−) ejection out of a PPY film was first chosen as a model system and the results obtained with EC/ICP-AES were found to be comparable with values deduced by electrochemical qu...
متن کامل92 Biostimulation
Biostimulation is one of the most mature methods of bioremediation of hydrocarbons, yet recent advances in geophysics, stable isotope analyses, and molecular microbiology promise dramatic increases in the depth, breadth, and throughput of biostimulation strategies. Using a systems biology approach we can now understand not only what microbes are present, but their in situ activities to trace nu...
متن کامل0 v 1 2 5 Ju n 19 92 Two Dimensional Quantum Gravity Coupled to Matter
A classical two dimensional theory of gravity which has a number of interesting features (including a Newtonian limit, black holes and gravitational collapse) is quantized using conformal field theoretic techniques. The critical dimension depends upon Newton's constant, permitting models with d = 4. The constraint algebra and scaling properties of the model are computed.

Lie-algebraic approach to the theory of polynomial solutions. II. Differential equations in one real and one Grassmann variables and 2x2 matrix differential equations ABSTRACT A classification theorem for linear differential equations in two variables (one real and one Grassmann) having polynomial solu-tions(the generalized Bochner problem) is given. The main result is based on the consideratio...

A very weakly coupled scalar field with mass m and initial vacuum expectation value V will provide enough mass to close the universe provided V ≃ (3 × 10 8 GeV)(100 GeV/m) 1/4. We discuss possible models in which such a field could arise. (a) Electronic address (internet): [email protected].
