A floor slope of 1/100 or less would usually not be detected by walking across the floor, and up to 1/75 may not be detected by some occupants (Ref. 1).These slopes suggest that significant deflections can occur and not be detected.
Che (interjection) Che (Spanish: [tÊe], Portuguese: tchÃª [ËtÊe]; Valencian: xe [ËtÊe]) is an interjection (i.e. a vocative expression) commonly used in Argentina, Uruguay, and in the Spanish autonomous community of Valencia.
In other Latin American countries, the term che can be used to refer to someone from Argentina. For example, the famous Argentine revolutionary Ernesto Che Guevara earned his nickname from his frequent use of the expression, which to his Cuban comrades in the Cuban Revolution, was a curious feature of his idiolect.
