K-55 (Kansas Highway)
K-55 is a west–east state highway in the U.S. state of Kansas. The highway's western terminus is at U.S. Route 81 (US-81) roughly north of Wellington and the eastern terminus is at K-15 in Udall. It passes through the city of Belle Plaine. The road's westbound terminus is a triangle-type intersection. Just before the western terminus, the road passes under the Kansas Turnpike, although there is no intersection. Turnpike access is available at K-53 to the north and US-160 to the south near Wellington. Before state highways were numbered in Kansas there were auto trails. K-55's western terminus closely follows the Meridian Highway and the South West Trail. It was first designated a state highway by 1927, and at that time ran from US-81 in Belle Plaine southeast to K-12 in Oxford. A year later, it had been realigned to travel east from US-81 to K-15 west of Udall. By 1945, a new alignment of K-15 had been completed, at which time K-55 was extended east to the new alignm ...

K-55 (missile)
The Kaliningrad K-5 (NATO reporting name AA-1 ''Alkali''), also known as RS-1U or product ShM, was an early Soviet air-to-air missile. History The development of the K-5 began in 1951. The first test firings were in 1953. It was tested (but not operationally carried) by the Yakovlev Yak-25. The weapon entered service as the Grushin/Tomashevich (russian: Грушин/Томашевич) RS-2U (also known as the R-5MS or K-5MS) in 1957. The initial version was matched to the RP-2U (Izumrud-2) radar used on the MiG-17PFU, MiG-19PM. An improved variant, K-5M or RS-2US in PVO service, entered production in 1959, matched to the RP-9/RP-9U (Sapfir) radar of the Sukhoi Su-9. The People's Republic of China developed a copy under the designation PL-1, for use by their J-6B fighters. The difficulties associated with beam-riding guidance, particularly in a single-seat fighter aircraft, were substantial, making the 'Alkali' primarily a short-range anti-bomber missile. Around 1967 the K ...

K55 Howitzer
The M109 is an American 155 mm turreted self-propelled howitzer, first introduced in the early 1960s to replace the M44. It has been upgraded a number of times, most recently to the M109A7. The M109 family is the most common Western indirect-fire support weapon of maneuver brigades of armored and mechanized infantry divisions. The M109 has a crew of four: the section chief/commander, the driver, the gunner, and the ammunition handler/loader. The chief or gunner aims the cannon left or right (deflection) and up and down (quadrant). The British Army replaced its M109s with the AS-90. Several European armed forces have or are currently replacing older M109s with the German PzH 2000. Upgrades to the M109 were introduced by the U.S. (see variants) and by Switzerland (KAWEST). With the cancellation of the U.S. Crusader and Non-Line-of-Sight Cannon, the M109A6 ("Paladin") will likely remain the principal self-propelled howitzer for the U.S. until the new M1299 enters service.

Keystone K-55 Pronto
The Keystone K-55 Pronto was a mail plane developed in the United States in the late 1920s. Design and development The Pronto was a conventional single-bay, unequal-span biplane design with slightly staggered wings. The pilot sat in an open cockpit, in tandem with a second cockpit that could carry two passengers side-by-side. The fixed, tailskid undercarriage had divided main units. A number of these aircraft were purchased by the government of Peru. Operated by the aviation arm of the Peruvian Navy, these aircraft initiated the first airmail service into the Peruvian Amazon. The first flight of this service was made by two Prontos, piloted by Leonardo Alvariño Herr and Harold B. Grow from Lima to San Ramón on 26 October 1927. At least one Peruvian Pronto was fitted with pontoons and used to survey the Amazon River for locations suitable for seaplane operations. In the Colombia-Peru War one Peruvian K-55 flown by Lieutenant Suero was captured by the Colombian Army. Op ...

Potassium-55
Potassium () has 26 known isotopes from to , with the exception of still-unknown , as well as an unconfirmed report of . Three of those isotopes occur naturally: the two stable forms (93.3%) and (6.7%), and a very long-lived radioisotope (0.012%) Naturally occurring radioactive decays with a half-life of 1.248×109 years. 89% of those decays are to stable by beta decay, whilst 11% are to by either electron capture or positron emission. has the longest known half life for any positron-emitter nuclide. The long half-life of this primordial radioisotope is caused by a highly spin-forbidden transition: has a nuclear spin of 4, while both of its decay daughters are even–even isotopes with spins of 0. occurs in natural potassium in sufficient quantity that large bags of potassium chloride commercial salt substitutes can be used as a radioactive source for classroom demonstrations. is the largest source of natural radioactivity in healthy animals and humans, greater ...
