Nuclear family. An American nuclear family composed of the mother, father, and their children, c. 1955. A nuclear family (also known as an elementary family, atomic family, or conjugal family) is a family group consisting of parents and their children (one or more), typically living in one home residence. It is in contrast to a single-parent ...
The liquid drop model is one of the first models of nuclear structure, proposed by Carl Friedrich von Weizsäcker in 1935. [5] It describes the nucleus as a semiclassical fluid made up of neutrons and protons, with an internal repulsive electrostatic force proportional to the number of protons. The quantum mechanical nature of these particles ...
CERN. The European Organization for Nuclear Research, known as CERN (/ sɜːrn /; French pronunciation: [sɛʁn]; Conseil européen pour la Recherche nucléaire), is an intergovernmental organization that operates the largest particle physics laboratory in the world. Established in 1954, it is based in Meyrin, western suburb of Geneva, on the ...
Nuclear DNA. Nuclear DNA (nDNA), or nuclear deoxyribonucleic acid, is the DNA contained within each cell nucleus of a eukaryotic organism. [1] It encodes for the majority of the genome in eukaryotes, with mitochondrial DNA and plastid DNA coding for the rest. It adheres to Mendelian inheritance, with information coming from two parents, one ...
The nuclear force (or nucleon–nucleon interaction, residual strong force, or, historically, strong nuclear force) is a force that acts between hadrons, most commonly observed between protons and neutrons of atoms. Neutrons and protons, both nucleons, are affected by the nuclear force almost identically.
A nuclear pore is a channel as part of the nuclear pore complex (NPC), a large protein complex found in the nuclear envelope of eukaryotic cells. The nuclear envelope (NE) surrounds the cell nucleus containing DNA and facilitates the selective membrane transport of various molecules. The nuclear pore complex predominantly consists of proteins ...
Gravelines Nuclear Power Station. The Gravelines Nuclear Power Station is a nuclear power plant located near the commune of Gravelines in Nord, France, approximately 20 km (12 mi) from Dunkerque and Calais. Its cooling water comes from the North Sea. The plant consists of 6 nuclear reactors of 900 MW each.
In nuclear physics, an atomic nucleus is called a halo nucleus or is said to have a nuclear halo when it has a core nucleus surrounded by a "halo" of orbiting protons or neutrons, which makes the radius of the nucleus appreciably larger than that predicted by the liquid drop model. Halo nuclei form at the extreme edges of the table of nuclides ...
