    Experimental test of the compatibility of the definitions of the electromagnetic energy density and the Poynting vector

    Full text link
    It is shown that the generally accepted definition of the Poynting vector and the energy flux vector defined by means of the energy density of the electromagnetic field (Umov vector) lead to the prediction of the different results touching electromagnetic energy flux. The experiment shows that within the framework of the mentioned generally accepted definitions the Poynting vector adequately describes the electromagnetic energy flux unlike the Umov vector. Therefore one can conclude that a generally accepted definitions of the electromagnetic energy density and the Poynting vector, in general, are not always compatible.Comment: Revtex-file vithout figures.

    Estudio de los aspectos teórico-prácticos del delito de trata de personas con fines de explotación sexual y su prueba en el proceso penal acusatorio (Tema Central)

    El delito de trata de personas es considerado como un tema de interés actual para la sociedad, en vista de que se encuentra catalogado como la nueva forma de esclavitud moderna, el entender que el término “trata” el término oficial utilizado por Naciones Unidas para hacer referencia al comercio de seres humanos y a la explotación por parte de terceros a estos, especialmente en los ámbitos: sexual, laboral, militar, religioso e incluso familiar, ha permitido que nuestro país, debido a los compromisos adquiridos con la comunidad internacional, adopte el principio de la debida diligencia para implementar políticas destinadas a la prevención, persecución y protección en esta clase de delito, y que cada vez su estudio y conocimiento general se debe incrementar para evitar que existan más víctimas de un delito de lesa humanidad, como está considerado la trata de personas

    On Another Form of the Energy Density for Electromagnetic Fields and Its Relation to the Electrokinetic Field

    By virtue of the existence so called electrokinetic field encountered in electromagnetic phenomena, a new form of the energy density of the electromagnetic field is obtained. &nbsp

    On the mathematical necessity of the co-existence of electromagnetic fields of the non-standard polarity with the standard electromagnetic fields in the case of the existence of Dirac monopoles

    In this brief note we adduce the mathematical rationale of the necessity of the existence of the electromagnetic field of the non-standard polarity if the magnetic charges (Dirac monopoles) exist in reality

    About non-radiation of a charge moving with acceleration and “free” electromagnetic field

    In this brief note we discuss some ambiguities in the description of the process of radiation of an accelerated charge and in the description of the so-called “free” electromagnetic (electric) field

    Spatial curvature as a distorted mapping of Euclidean space

    Get PDF
    The article makes an attempt to understand the essence of the curvature of space-time in general relativity. To clarify the physical meaning, a mapping method is used, based on the analogy with the philosophical categories “phenomenon-essence-observer”. It is shown that curvilinear space can exist only inside the Euclidean space. It is also shown that the interpretation of the phenomenon called the “Big Bang” is incorrect

    International journal of engineering sciences & research technology , The postulate of the equivalence of masses or the law of their proportionality?

    Get PDF
    The main sources of GTR problems are analyzed. First, physicists and geometers in explaining phenomena do not take into account the simultaneous existence of two spaces (linear space-time and curvilinear space-time). Secondly, it is shown that the initial postulate on the equivalence of inertial and gravitational masses is erroneous from the point of view of philosophy and physics.Moreover, experimental testing of the hypothesis is difficult because of the lack of accuracy of the measuring devices. It is shown that gravity can be considered as a quadratic effect of electrodynamics. The postulate on the equivalence of inertial and gravitational masses must be replaced by the law of proportionality of the inertial mass of the body and its gravitational charge. The new approach fits in perfectly with the idea of J. Thomson on the electromagnetic nature of material bodies
