Beluga caviar Service to ban in 2005 the importation of beluga caviar which originated in the Caspian Sea and Black Sea basin. In 2006, the Convention on International Trade in Endangered Species (CITES) suspended all trade made with the traditional caviar-producing regions of the Caspian and Black Seas (Beluga, Ossetra and Sevruga), (Azerbaijan, Bulgaria, China, Iran, Kazakhstan, Romania, Russia, Serbia and Montenegro, Turkmenistan, and Ukraine) due to the producing countries' failure to apply international regulations and recommendations. Caviar from Iran is exempted from the ban. Iran is considered by CITES to practice effective conservation and policing of its fisheries. In January 2007,
Capacitor types other capacitor types are negligible in terms of value and quantity compared with the above types. Capacitor types Capacitors are manufactured in many forms, styles, lengths, girths, and from many materials. They all contain at least two electrical conductors (called "plates") separated by an insulating layer (called the dielectric). Capacitors are widely used as parts of electrical circuits in many common electrical devices. Capacitors, together with resistors, and inductors, belong to the group of "passive components" used in electronic equipment. Although, in absolute figures, the most common capacitors are integrated capacitors (e.g. in DRAMs or flash memory structures), this article
