It has been recently demonstrated, [3,11], that according to the principle of release constraints, absence of shear stresses in the Euler equations must be compensated by additional degrees of freedom, and that led to a Reynolds-type enlarged Euler equations (EE equations) with a doublevalued velocity field that do not require any closures. In the first part of the paper, the theory is applied to turbulent mixing and illustrated by propagation of mixing zone triggered by a tangential jump of velocity. A comparison of the proposed solution with the Prandtl’s solution is performed and discussed. In the second part of the paper, a semi-‐viscous version of the Navier-‐Stokes equations is introduced. The model does not require any closures since the number of equations is equal to the number of unknowns. Special attention is paid to transition from laminar to turbulent state. The analytical solution for this transition demonstrates the turbulent mean velocity profile that qualitatively similar to celebrated logarithmic law.

In this paper, we configured a system with negative input impedance by a pair of Yagi-Uda antennas. The two Yagi antennas were placed face to face feeding by the same source. The input impedance is the sum of self-impedance and mutual impedance. Since Yagi antenna has significantly reduced self-impedance and amplified mutual impedance, it is anticipated that this system present negative input impedance.

In this paper, I will review some inadequacies of Schrödinger equation. Then I will discuss George Shpenkov's interpretation of classical wave equation and two other authors' wave equations. According to Shpenkov, the classical wave equation can be used to derive a periodic table of elements -which is close to Mendeleyev's periodic table-, and also other phenomena related to the structure of molecules. It is argued here that one may arrive at new energy methods using this classical wave equation as starting point. It is suggested that Shpenkov's interpretation of classical wave equation can complement Schrödinger equation.
