In these applications, it is the long and difficult path and the formation of controlled fluid vortices plus some ...
All free emblems, seals, logos and other similar insignia are acceptable for use with this template to the exclusion of heraldic coats of arms. Where there is a doubt, for example Cold-War-Era Eastern European emblems and seals that often incorporated some elements of heraldic design, this template errs on the side of inclusion.
To change this template's initial visibility, the |state= parameter may be used: {{US state seals | state = collapsed}} will show the template collapsed, i.e. hidden apart from its title bar. {{US state seals | state = expanded}} will show the template expanded, i.e. fully visible.
