The disadvantage of the ski-jump is the penalty it exacts on aircraft size, payload, and fuel load (and thus range); heavily laden aircraft can not launch using a ski-jump because their high loaded weight requires either a longer takeoff roll than is possible on a carrier deck, or assistance from a catapult or JATO rocket. For example, the Russian Su-33 is only able to launch from the carrier Admiral Kuznetsov with a minimal armament and fuel load. Another disadvantage is on mixed flight deck operations where helicopters are also present such as a US Landing Helicopter Dock or Landing Helicopter Assault amphibious assault ship a ski jump is not included as this would eliminate one or more helicopter landing areas, this flat deck limits the loading of Harriers but is somewhat mitigated by the longer rolling start provided by a long flight deck compared to many STOVL carriers.

The first geographical entity that was called Armenia by neighboring peoples (such as by Hecataeus of Miletus and on the Achaemenid Behistun Inscription) was established in the late 6th century BC under the Orontid dynasty within the Achaemenid Persian Empire as part of the latters' territories, and which later became a kingdom. At its zenith (9565 BC), the state extended from the Caucasus all the way to what is now central Turkey, Lebanon, and northern Iran. The imperial reign of Tigranes the Great is thus the span of time during which Armenia itself conquered areas populated by other peoples.
When was Armenia at its largest?

Shuman built the world's first solar thermal power station in Maadi, Egypt, between 1912 and 1913. Shuman's plant used parabolic troughs to power a 4552 kilowatts (6070 hp) engine that pumped more than 22,000 litres (4,800 imp gal; 5,800 US gal) of water per minute from the Nile River to adjacent cotton fields. Although the outbreak of World War I and the discovery of cheap oil in the 1930s discouraged the advancement of solar energy, Shuman's vision and basic design were resurrected in the 1970s with a new wave of interest in solar thermal energy. In 1916 Shuman was quoted in the media advocating solar energy's utilization, saying:
