A third similar question arises in the potential representation of fields E and B. Conventionally, a magnetic scalar potential is not included as part of the solution of Maxwell s equations. However, there is no a priori prohibition for the existence of such solution within a general formulation. Sections III. A—III.E consider previous issues in some detail. 

Integrating Eq. (13) is executed over the sphere surface. Since the potentials on the surfaces of the spheres are equal inside and outside, we can use either potentials representations. If the surface charges are constant, integration leads to calculations of the spherical functions integrals over the total surfaces of the spheres. After integrating Eq. (13), taking into account the expansions (Eq. 5), we obtain for the free energy... 

For field-induced properties, one can adopt the usual scalar potential representation, and in the clamped lattice approximation the dipolar perturbation potential is given by... 

The Maxwellian molecules are useful in exploratory calculations in which a differentiable potential function is needed. For these molecules [66] the in-termolecular force between pairs at a distance r apart is of the form where K is a constant. Adopting this particular potential representation the solution of the equation of transfer reduces to a feasible problem, thereby Maxwell [66] obtained analytical expressions for the transport coefficients as mentioned earlier.

The MTHF antenna is exposed on the surface, whereas the FADH catalytic cofactor is buried within the core of the a-helical domain. (B) Surface potential representation. Blue, basic residues red, acidic residues white, hydrophobic residues. Note the positively charged groove running diagonally the length of the protein and the hole (marked by a square) with asymmetric charge distribution along the side walls and leading to the flavin located in the bottom.

Left, ribbon representation. Right, surface potential representation.

In the description given outlining electrochemical systems in which a current flows, key parameters include the variations of the anodic and cathodic polarisations (or overpotentials if applicable) as a function of current and time. These relationships are generally represented in the form of current-potential curves of an electrode, /= f(E), where E is the voltage between the electrode in question and a reference electrode . The experimental results can also be presented in the form of current density-potential curves. However, when the study concerns the whole electrochemical system and is not just focused on the working electrode, it is best to keep the current-potential representation I... 

Some books also call these curves polarisation curves, especially those which choose to represent the potential as a function of the current. The Evans diagrams, depicting the use of currents in corrosion, provide an example of such a type of representation. In this document, we will only choose to use the current-potential representation which is quite a natural choice if the data are recorded using potentiostatic techniques. 

With the above potential representation, s tions of the chain many bonds apart may cross and overlap and the conformation is literaUy unperturbed by long-range (non-local) interactions. In order to compute equilibrium ava-f properties of our cemtinuous unperturbed dmins, we rample their configuration space through a fast Monte Carlo scheme where the only dementary move employed is simple rotation, performed exactly as described above for the bulk simulation. Note that reptations must be attempted in both directions along the chain in order for the simulation to be microscopically reversible.

The expansion coefficients and exponents Df and df. are obtained by least-squares fitting such that the weighted deviation between the original form of the radial part of the spin-orbit operator and the potential representation is minimized. 

Next, one may consider the forces associated with these parameters variations this way, in analogy with the model of the elastic forces, the bonds in the various potentials representations P(X, Y) can be written considering the adjacent (matrix) variation of the system s parameters so that the action of the conjugated forces having the forms ... 

However, there are other potential representations that do not diminish the dignity of workers in the nuclear sector. In fact, the subcontractors depicted in Grand Central do not seem to be representative of this type of worker. While the film s bias helps to nourish the image of nuclear power in the popular imagination, it does not acknowledge the professionalism of subcontractors. It is clear that there is a part of the labour force in the nuclear sector that leads a precarious existence, and questions can be asked about why operators find it necessary to subcontract 80% of maintenance...

The MCTDH method is rather new, and there are still several aspects that have to be improved. Besides the just-mentioned potential representation problem, we are cuiTently trying to refine the numerical integrators for solving the nonlinear MCTDH equations of motion. ...
