### A Navier and Stokes Equations Try

**Authors:** Thomas Pierre Nicolas Jean Brouard

**Comments:** 6 Pages.

Here is proposed a solving Navier and Stokes equations three dimensions fluid model problem, described in cylindrical coordinates, composed of null radial and vertical velocities, and of a cross-radial velocity. Equations conditions verifications and calculation description leading to the expression of pressure are given. A description of the problem can be found here: http://www.claymath.org/sites/default/files/navierstokes.pdf

### Incompatibility of the Dirac-Like Field Operators with the Majorana Anzatzen

**Authors:** Valeriy V. Dvoeglazov

**Comments:** 19 Pages. Extended version of viXra:1809.0241 to include spin 1.

In the present article we investigate the spin-1/2 and spin-1 cases in different bases. Next, we look for relations
with the Majorana-like field operator. We show explicitly incompatibility of the Majorana anzatzen with the Dirac-like field operators in both the original Majorana theory and its generalizations. Several explicit examples are presented for higher spins too. It seems that the calculations in the helicity basis give mathematically and physically reasonable results only.
