* Atomic units, a system of units convenient for atomic physics and other fields

* 1958 – The American Atomic Energy Commission, with supporting military units, carries out an underground nuclear weapon test at the Nevada Test Site, just north of Las Vegas, Nevada.

Atomic units ( au or a. u.

Atomic units, like SI units, have a unit of mass, a unit of length, and so on.

As a result the federal regulator, the Atomic Energy Control Board, because of the decision to delay the upgrade of the emergency shutdown systems at the station, required the corporation to obtain regulatory approval before restarting the units.

The Therac-25 was a radiation therapy machine produced by Atomic Energy of Canada Limited ( AECL ) after the Therac-6 and Therac-20 units ( the earlier units had been produced in partnership with CGR of France ).

To accomplish its mission, SWC redesignated numerous units that had been under the USAF Field Office of Atomic Energy with no change in station.

* Atomic units ( au ) are a convenient system of units of measurement used in atomic physics, particularly for describing the properties of electrons.

They are also similar to Atomic units but set the speed of light to unity and allow Planck's constant to float.

On May 2, 1975, the Canadian Atomic Energy Commission authorized the construction of two 640-MW units within a site that can accommodate a maximum of four reactors.

Atomic orbitals are typically categorized by n, l, and m quantum numbers, which correspond to the electron's energy, angular momentum, and an angular momentum vector component, respectively.

Atomic orbitals are the basic building blocks of the atomic orbital model ( alternatively known as the electron cloud or wave mechanics model ), a modern framework for visualizing the microscopic behavior of electrons in matter.

Atomic orbitals can be the hydrogen-like " orbitals " which are exact solutions to the Schrödinger equation for a hydrogen-like " atom " ( i. e., an atom with one electron ).

Atomic semantics are defined for a variable with a single writer but multiple readers.

Atomic semantics are defined formally in Lamport's " On Interprocess Communication " Distributed Computing 1, 2 ( 1986 ), 77-101.

Atomic physics underlies the workings of chemistry, which studies emergent properties that in turn are the basis of biology.

" Atomic " data, that is, data at the lowest level of detail, are stored in the data warehouse.

Atomic properties like the ionization energy are often quoted in electron volts.

According to the International Atomic Energy Agency there are at least 100 research reactors in the world fueled by highly enriched ( weapons-grade / 90 % enrichment uranium ).

Professor John Mueller of Ohio State University, the author of Atomic Obsession, has also dismissed the need to interfere with Iran's nuclear program and expressed that arms control measures are counterproductive.

Atomic absorption lines are observed in the solar spectrum and referred to as Fraunhofer lines after their discoverer.

A summary of the amounts of radioactive wastes and management approaches for most developed countries are presented and reviewed periodically as part of the International Atomic Energy Agency ( IAEA ) Joint Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive Waste Management.

The Atomic orbital | orbitals of the hydrogen atom are descriptions of the probability distribution s of an electron bound state | bound to a proton.

International Atomic Time ( TAI ) is the primary international time standard from which other time standards, including UTC, are calculated.

; Atomic operations: Shared data are accessed by using atomic operations which cannot be interrupted by other threads.

Atomic bombs are based on the theory of nuclear fission, that when a large atom splits it releases a massive amount of energy.

Atomic models will consist of a single nucleus that may be surrounded by one or more bound electrons, whilst molecular models are typically concerned with Molecular Hydrogen and it's Molecular hydrogen ion.

Its Atomic number and atomic symbol are unknown.

The remaining bomb casings are located at the Russian Atomic Weapon Museum, Sarov ( Arzamas-16 ), and the Museum of Nuclear Weapons, All-Russian Research Institute of Technical Physics, Snezhinsk ( Chelyabinsk-70 ).

In various forms, other designs are under development by MIT, University of California at Berkeley, General Atomics ( U. S .), the Dutch company Romawa B. V., Adams Atomic Engines, and Idaho National Laboratory.

These are funded by various national agencies like the Department of Science and Technology, Department of Electronics, Department of Space, Aeronautical Development Agency, Department of Atomic Energy, and Oil and Natural Gas Commission ( ONGC ).

* 1985-1990 in the Film series Back to The Future, references to the Atomic Age and uses of Nuclear Energy are broadly explored ; for example the use of Plutonium in the time machine, the concept of " Mr. Fusion " ( a futuristic small scale fusion reactor for domestic use that can use garbage as fuel ) and references to the common 1950s conceptions of the Atomic Age.

There have also been numerous clones made ( and are still being made ) such as Atomic Tanks, Nasty Armoured Tanks of War, xscorch ( Open Source clone ), Scorched 3D, which attempt to modernize the gameplay and graphics, and others such as Charred Dirt that take a different approach by using a unique graphical style.

* Beginning in the 1990s, nostalgia stores that specialize in selling modern furniture or artifacts from the 1950s often have included the words Atomic Age as part of the name of, or advertising for the store.

Herzberg authored some classic works in the field of spectroscopy, including Atomic Spectra and Atomic Structure and the encyclopaedic four volume work: Molecular Spectra and Molecular Structure, which is often called the spectroscopist's bible.

The Atoms for Peace symbol mounted over the door to the American swimming pool reactor building during the 1955 International Conference on the Peaceful Uses of Atomic Energy in Geneva, often called the Atoms for Peace conference.

" In the 1980s, Eddie Van Halen, for instance, often used the MXR Phase 90 as part of his signal chain, for example in the instrumental " Eruption " and on the song " Atomic Punk ".

The De Scalzi led lineup, often mistakenly referred to as New Trolls Atomic System, released their first album in 1973 with arrangements similar to the ones used previously in Concerto grosso per i New Trolls.

Atomic diffusion in polycrystalline materials is therefore often modeled using an effective diffusion coefficient, which is a combination of lattice, and grain boundary diffusion coefficients.
