It was considered a model of inhomogeneous vector field within an associative algebra (Clifford algebra) on generalized coordinates. It is shown the derivation of the equations: two systems of Maxwell equations as a single equation, conservation laws 4-current and Einstein field equations. The geometrical interpretation for 4- current was given. Also the nontrivial "law of conservation of 4-dimensional curl of current" was received.

SciReg.org register system reliably and effectively protects the rights of authors by fixing the publication date and confirming the authorship of any kind of materials. Unlike conventional systems, SciReg is a comprehensive register having no limitations whatsoever as regards to the subject matter of copyright. It is the SciReg register system where the author of a material becomes a registered author of his/her particular work – invention, melody, text, scientific publication, or other material, and where he/she can confirm his/her priority and copyright at any time. The SciReg register system protects the present-day science against pressure of corporations and scientific institutions, and influence of patent authorities – both moderators of the scientific, artistic and engineering progress. SciReg secures inherent human rights to intellectual property protection, scientific and creative results.
