Magnetohydrodynamics is a branch of science that deals with the dynamics of magnetic fields in electrically conducting fluids. The theory of MHD is that currents are induced in a moving conductive fluid by magnetic fields which creates forces on the fluids and changes the magnetic field itself. MHD applies to the fields of astrophysics and cosmology since matter of the universe is made up of plasma, interplanetary medium, interstellar medium.
High-impact journals are those considered to be highly influential in their respective fields. The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
