The cuneiform du sign, also kup, and sumerograms DU and GUB, is a common-use sign of the Epic of Gilgamesh, the 1350 BC Amarna letters, and other cuneiform texts. In the Akkadian language for forming words, it can be used syllabically for: du, or kup (and ku, up); also alphabetically for letters d, u, k, or p.
Natural uranium contains about 0.72% 235 U. Depleted uranium has lower mass fractions—up to three times less—of 235 U and 234 U than natural uranium. Since 238 U has a much longer half-life than the lighter isotopes, DU is about 40% less radioactive than natural uranium.
In atomic physics and quantum chemistry, the Aufbau principle (/ ˈ aʊ f b aʊ /, from German: Aufbauprinzip, lit. 'building-up principle'), also called the Aufbau rule, states that in the ground state of an atom or ion, electrons first fill subshells of the lowest available energy, then fill subshells of higher energy.
For hydrocarbons, the DBE (or IHD) tells us the number of rings and/or extra bonds in a non-saturated structure, which equals the number of hydrogen pairs that are required to make the structure saturated, simply because joining two elements to form a ring or adding one extra bond (e.g., a single bond changed to a double bond) in a structure reduces the need for two H's.
IKEA, for instance, does this to reflect the widespread use of the du form in Sweden (see Du-reformen). In Germany, an old custom (called Brüderschaft trinken, drinking brotherhood) involves two friends formally sharing a bottle of wine or drinking a glass of beer together to celebrate their agreement to call one another du rather than Sie.
An example is a tax return; filling one out is required in order for the amount of tax one owes to be determined. A form may also be a request for a tax refund. Forms may be filled out in duplicate (or triplicate, meaning three times) when the information gathered on the form needs to be distributed to several departments within an organisation.
