Conceptual Evolution of Peace Journalism: Origin, Development, Critiques and Contributions to Peace Studies
(Cartagena de Indias, 2022)The mass media have focused on reporting more on issues of war than on peace. Hence, peace journalism emerges as a narrative option that contributes to the peaceful resolution of conflicts, in a context where truth, rigorous ... -
Concerning Dynamic Effects in Pipe Systems with Two-Phase Flows: Pressure Surges, Cavitation, and Ventilation
(Cartagena de Indias, 2022-07-31)The risks associated with unsteady two-phase flows in pressurized pipe systems must be considered both in system design and operation. To this end, this paper summarizes experimental tests and numerical analyses that ... -
Conformastatic disk-haloes in Einstein-Maxwell gravity
(2013)We present a relativistic model describing a thin disk surrounded by a halo in the presence of an electromagnetic field. The model is obtained by solving the Einstein-Maxwell equations on a particular conformastatic spacetime ... -
Conformastationary disk-haloes in Einstein–Maxwell gravity
(Springer New York LLC, 2015)An exact solution of the Einstein–Maxwell field equations for a conformastationary metric with magnetized disk-haloes sources is worked out in full. The characterization of the nature of the energy momentum tensor of the ... -
