Based on the definition of the term, “dissertation” is an exclusively scientific work, the form of which is strictly defined.

 The scientific and qualification nature of the dissertation should be prepared for scientific defense and subsequently obtaining a scientific degree.  Scientific research should be carried out directly by the author, and the work should be a collection of new scientific results and provisions.

 Thus, the dissertation is a confirmation of the personal contribution of the applicant to the solution of an urgent scientific problem.  New solutions proposed by the author should be reasoned and supported by facts.  In addition, they need to be critically correlated with work directions already known to the scientific world.

 Confirmation of new author’s decisions of the author are the information sources indicated in the dissertation.  They contain information on the basis of which the dissertation was written.  As a result of this, the author presents to the public defense a full-fledged scientific work indicating a personal contribution to a particular scientific branch of knowledge.
