In science and technology, an arbitrary unit (abbreviated arb. unit, see below) or procedure defined unit (p.d.u.) is a relative unit of measurement to show the ratio of amount of substance, intensity, or other quantities, to a predetermined reference measurement. The reference measurement is typically defined by the local laboratories or dependent on individual measurement apparatus. It is the… Web17 hours ago · The Federal Reserve on Friday approved UBS Group AG’s takeover of the US subsidiaries of Credit Suisse Group AG.
