Prefabricated Buildings. Modular buildings, commonly called prefabricated buildings, are made from all the same materials and meet all the same building International Building Codes (IBC) as conventionally built structures. The difference is the process.
Gold Standard Act. The Gold Standard Act of the United States was passed in 1900 (approved on March 14) and established gold as the only standard for redeeming paper money, stopping bimetallism (which had allowed silver in exchange for gold). It was signed by President William McKinley.
Other times, gold standard does not refer to the best performing test available, but the best available under reasonable conditions. For example, in this sense, a MRI is the gold standard for brain tumour diagnosis, though it is not as good as a biopsy. In this case the sensitivity and specificity of the gold standard are not 100% and it is said to be an imperfect gold standard or alloyed gold standard.
