Nuclear bodies. Nuclear bodies (also known as nuclear domains or nuclear dots) are biomolecular condensates, membraneless structures found in the cell nuclei of eukaryotic cells. [1] Nuclear bodies include Cajal bodies, the nucleolus, nuclear speckles (also called splicing speckles), histone locus bodies, and promyelocytic leukemia protein (PML ...
The gap between the inner and outer Van Allen belts is sometimes called the "safe zone" or "safe slot", and is the location of medium Earth orbits. The gap is caused by the VLF radio waves, which scatter particles in pitch angle, which adds new ions to the atmosphere. Solar outbursts can also dump particles into the gap, but those drain out in ...
An area near the Trinity site is designated the Permanent High Explosive Test Site (PHETS) and was used in the 1980s to host very large ANFO blasts for international testing of military gear. The Trinity nuclear site was originally private property taken over by the Army to test the plutonium implosion weapon, the first nuclear explosion on Earth.
t. e. The Elephant's Foot is the nickname given to a large mass of corium, composed of materials formed from molten concrete, sand, steel, uranium, and zirconium. The mass formed beneath Reactor 4 of the Chernobyl Nuclear Power Plant, near Pripyat, Ukraine, during the Chernobyl disaster of 26 April 1986, and is noted for its extreme radioactivity.
The 12 founding member states of CERN in 1954. [13]The convention establishing CERN [14] was ratified on 29 September 1954 by 12 countries in Western Europe. [15] The acronym CERN originally represented the French words for Conseil Européen pour la Recherche Nucléaire ('European Council for Nuclear Research'), which was a provisional council for building the laboratory, established by 12 ...
Lake Karachay (Russian: Карача́й), sometimes spelled Karachai or Karachaj, was a small lake in the southern Ural Mountains in central Russia.Starting in 1951, the Soviet Union used Karachay as a dumping site for radioactive waste from Mayak, the nearby nuclear waste storage and reprocessing facility, located near the town of Ozyorsk (then called Chelyabinsk-40).
Nuclear physics. In nuclear physics, the valley of stability (also called the belt of stability, nuclear valley, energy valley, or beta stability valley) is a characterization of the stability of nuclides to radioactivity based on their binding energy. [1] Nuclides are composed of protons and neutrons.
A model of the atomic nucleus showing it as a compact bundle of the two types of nucleons: protons (red) and neutrons (blue).In this diagram, protons and neutrons look like little balls stuck together, but an actual nucleus (as understood by modern nuclear physics) cannot be explained like this, but only by using quantum mechanics.
