The research has been done in the field of Field Work Practice to synthesize superconductors Bi1,6Pb0,4Sr2Ca2Cu3O10+x for Meissner test using solid reaction method. The objective of this research is to make superconductor Bi1,6Pb0,4Sr2Ca2Cu3O10 x with sol... see more

The two interacting complex scalar fields at finite density is considered in the mean field approximation. It is shown that although the symmetry is spontaneously broken for the chemical potentials bigger than the meson masses in vacuum, but the Goldstone... see more

La concepción teórico dominante, supone una subordinación y dependencia de los modelos respecto de las teorías. Nos proponemos alterar la noción de independencia entre modelo y teoría que ha sido concebida como relativa e histórica para el caso de la supe... see more

Alexander von Humboldt hat auf der Grundlage des Wissens seiner Zeit in den Schlussfolgerungen zu seinen Messungen zum Boden, zur Luft und zum Wasser gelegentlich auch offene Fragen formuliert und Vermutungen geäußert. Es ist das Ziel dieses Beitrages, fr... see more

AbstractFaecal phosphorous and nitrogen can be used as indicators of the nutritive content of the veld. Dietary P concentrations can be predicted with reasonable accuracy from faecal P concentrations in faeces of caged impala rams using a simple linear re... see more

The physical properties of a relativistic model for complex scalar field at finite density are studied. It is shown that the boson is condensed when the critical chemical potential is equal to the boson mass in vacuum and the system undergoes the phase tr... see more

Interrogation is an essential component of a comprehensive view of torture and deserves special reflection. In interrogational torture, physical and psychological techniques serve the purpose of creating the physical, cognitive and emotional exhaustion in... see more
