coupling constant can provide information about stereochemistry. The Karplus equation describes how the coupling constant between two protons is affected by the dihedral angle between them. The equation follows the general format of J = A + B (cos θ) + C (cos 2θ), with the exact values of A, B and C dependent on several different factors.

the form of the axial currents as the continuity equation for the electromagnetic current. One of the main consequences of the PCAC relation for the axial current is that axial coupling of the constituent quarks, g Aq, is not equal to unity. Instead, it is related to the pion-quark coupling constant, g ˇq, via a Goldberger-Treiman relation

Torsional and axial vibrations are commonly dealt with during the selection of drivers or driven units and couplings, after all the individual equipment has been designed. For integrally-geared rotating machinery, the lateral, torsional, and axial vibrations are coupled together through the gear meshes and thrust collars.

The pure Gamow-Teller decay of the 6He decay allows to probe axial currents in a simple nuclear system. Contrary to the vector currents that are protected by the Conserved Vector Current hypothesis, axial currents could be changed in the nuclear medium leading to a renormalization of the axial coupling constant found in the decay of free neutrons.

It is the coefficients (i.e., the values of bn) that characterize a specific gauge theory. The gauge theory does not specify the magnitude of the coupling (this is the price for absorbing the infinities). Rather the theory tells us how the coupling varies with scale. The specific form for the running coupling provided in Eq. (32.2) is the one-

The axial type current is the result of a light-like Kaluza-Klein reduction from the 3+1 dimensional axial current in a similar way as the current in  is the reduced form of the 3+1 dimensional vector current. From the 2+1 dimensional point of wiev, with this coupling, the gauge eld would be coupled to the spin density of the matter.

Clearly, in this model, the elasticity of the material is assumed to be constant. If the beam is made of FGM, e.g., the elastic modulus of the material changes along either the lateral or the axial direction, the governing equation given previously is invalid. In the present work, the beam model is modiﬁed to suit a beam with axial FGM. In other
