Kh (Russian: Х ) was the class of double axled high-floor tramcars, which were built in Soviet Union in interbellum period.
 First vehicles were built in 1927 and delivered to Kharkov, Ukraine.
 First letter of city name, Cyrillic "Х" (usually transliterated as "Kh"), was selected as a designation of whole series.
 After Kharkiv, tramcars of this type were supplied to many Soviet cities and became most numerous in the fleets of many municipalities.
 In 1941, after the onset of Operation Barbarossa, their production was stopped for maximizing war efforts.
 The Kh-class tramcars were finally withdrawn from the city service in the mid-1960s as morally obsolete vehicles, their sturdy construction allowed them to be used much more.
 The small number of survived cars are preserved for museum purposes in Moscow, Nizhniy Novgorod, Saratov and few other cities.

Yoshi is an extinct genus of machairodontine sabertooth cat in the tribe Metailurini.
 Its fossils were described from Turolian deposits from the Miocene epoch of the Balkan Peninsula in 2014 and specimens from china once thought to belong to "Metailurus".
 It has been described as potentially being synonymous with "Metailurus", though this is difficult to confirm at present.
 The type specimen is a skull that bears remarkable similarities with the modern cheetah.
 "Yoshi" is intermediate in size between a lynx and cougar, and based on several as-yet unpublished skeletons, may have had a similar lifestyle to the cheetah, being better built for speed and fast pursuit than most other machairodonts, which were more suited to ambush and hunting large, relatively slow moving animals.
