Primordial gravitational waves in running vacuum cosmologies
(Elsevier B.V., 2017-01-01)
We investigate the cosmological production of gravitational waves in a nonsingular flat cosmology powered by a running vacuum energy density described by rho(Lambda) = rho(Lambda)(H), a phenomenological expression potentially ...
Desalination of water by reverse osmosis using gravitational potential energy and wind energy
(ELSEVIER SCIENCE BV, 2009)
This paper proposes ail alternative configuration to conventional reverse osmosis (RO) desalination systems by incorporating the use of gravitational potential energy. The proposal suggests a model that can be viewed as ...
Gauge Invariance of Gravitodynamical Potentials in the Jefimenko’s Generalized Theory of Gravitation
(Scientific Research Publishing, 2016-09)
In the Jefimenko’s generalized theory of gravitation, it is proposed the existence of
certain potentials to help us to calculate the gravitational and cogravitational fields,
such potentials are also presumed non-invariant ...

Gravitational waves from a very strong electroweak phase transition
(IOP Publishing, 2016-05)
We investigate the production of a stochastic background of gravitational waves in the electroweak phase transition. We consider extensions of the Standard Model which can give very strongly first-order phase transitions, ...
