First Book:

## THE DESIGN OF GEARINGS WITH HIGH EFFICIENCY

Development and diversification of machines and mechanisms with applications in all areas of scientific research requires new systematization and improvement of existing mechanical systems by creating new mechanisms adapted to the modern requirements; the gearing mechanisms are found today everywhere: in the industry of machinery construction, in energy industry, in aeronautics and aerospace, in electronics& Electrical, in oil industry, in mechatronics and robotics, etc. In this context this book attempts to bring a contribution to science and technology applied in the kinematic and dynamic analysis and synthesis of mechanisms with gearings. The book presents an original method to determine the efficiency of the gearing; the originality of this method relies on the eliminated friction modulus. With the relations presented in this paper, one can synthesize the gear’s mechanisms; the best efficiency can be obtained with the internal gearing when the drive wheel 1 is the ring.

An Atomic Model or A New Quantum Theory – About Negative Mass.

### A New Quantum Theory

I searched the electron radius on the net but I found a rather large value, re=2.8*10-15 [m] so

we calculated it and I and I found: re=7*10-16 [m],

Nucleus radius: rn=1-7*10-15 [m]

Proton radius: rp=1*10-15 [m]

One utilizes two times the Lorentz relation (5), the Niels Bohr generalisate equation (7), and a mass relation (4) which was deduced from the kinematics energy relation written in two modes: classical (1) and coulombian (2). Equalizing the mass relation (4) with Lorentz relation (5) one obtains the equation (6), which give us a relation between the electron speed square (v ^{2}) and the radius (r). The second relation (8), between v^{2} and r, has been obtained by equalizing the mass from Bohr’s equation (7) with the mass from Lorentz’s relation (5). In the system (8) – (6) eliminating the electron speed square (v^{2}), one determines the radius r, with that, the electron is moving around the nucleus; see the relation (18). The author realize by this a new atomic model, or a new quantum theory.*

In my opinion the gravitational field behaves like the magnetic and electric field.

Matter is configured in such a way as the negative mass to coexist with the positive mass. Although they are distributed equally positive and negative mass are configured differently order to support different electrical charges. Negative mass is one that draws positive masses and vice versa, the positive mass attracts negative masses.

In these conditions the generalized relativity theory can no longer be valid. The space in which we live, straight or curved, there is bound to create a temporary slide to attracts us.
