The cardiac cycle is the performance of the human heart from the beginning of one heartbeat to the beginning of the next. [1] It consists of two periods: one during which the heart muscle relaxes and refills with blood, called diastole, following a period of robust contraction and pumping of blood, called systole. [1]
In the far future (2 to 3 billion years), the rate at which carbon dioxide is absorbed into the soil via the carbonate–silicate cycle will likely increase due to expected changes in the sun as it ages. The expected increased luminosity of the Sun will likely speed up the rate of surface weathering. [13]

A Carnot cycle is an ideal thermodynamic cycle proposed by French physicist Sadi Carnot in 1824 and expanded upon by others in the 1830s and 1840s. By Carnot's theorem, it provides an upper limit on the efficiency of any classical thermodynamic engine during the conversion of heat into work, or conversely, the efficiency of a refrigeration system in creating a temperature difference through ...
Cori cycle. The Cori cycle (also known as the lactic acid cycle), named after its discoverers, Carl Ferdinand Cori and Gerty Cori, [1] is a metabolic pathway in which lactate, produced by anaerobic glycolysis in muscles, is transported to the liver and converted to glucose, which then returns to the muscles and is cyclically metabolized back to lactate.
USMC F-4 pilots claimed three enemy MiGs at the cost of one aircraft in air-combat. USAF F-4 Phantom crews scored 107 + 1 ⁄ 2 MiG kills (including 33 + 1 ⁄ 2 MiG-17s, eight MiG-19s and 66 MiG-21s) at a cost of 33 Phantoms in air-combat. [74] F-4 pilots were credited with a total of 150 + 1 ⁄ 2 MiG kills at a cost of 42 Phantoms in air-combat.
King Ranch is the largest ranch in the United States. At some 825,000 acres (3,340 km 2; 1,289 sq mi) [3] it is larger than both the land area of Rhode Island and the area of the European country Luxembourg. [4]
