| elementary particle interactions | The interactions of particles responsible for their scattering and transformations (decays and reactions). Because of interactions, an isolated particle may decay into other particles. Two particles passing near each other may transform, perhaps into the same particles but with changed momenta (elastic scattering) or into other particles (inelastic scattering). Interactions fall into three groups: strong, electromagnetic, and weak. (12 Dec 1998) |
|---|---|
| elementary particles | <radiobiology> at a nuclear-energy level: electron & positron - seem to be stable, proton - thought to be stable, life greater than 10^30 sec, neutron - decays in ?6 min unless its in a nucleus, which often extends its life. Other particles important for nuclear energy: Muon, neutrino (m, e, tau), photon, Muonic atoms, Pi-meson antiparticles (09 Oct 1997) |
| Zimmermann's elementary particle | <haematology> A discoid cell (3m diameter) found in large numbers in blood, important for blood coagulation and for haemostasis by repairing breaches (small breaks) in the walls of blood vessels. Platelet _ granules contain lysosomal enzymes, dense granules contain ADP (a potent platelet aggregating factor) and serotonin (a vasoactive amine). They also release platelet-derived growth factor which presumably contributes to later repair processes by stimulating fibroblast proliferation. Synonym: thrombocytes. (09 Oct 1997) |
|---|---|
| elementary bodies | Old term for virions, especially the largest virus particles, visible by light microscopy when stained. Synonym: platelet. (05 Mar 2000) |
| elementary granule | A particle of blood dust, or haemoconia. (05 Mar 2000) |
| elementary step | <chemistry> Reaction mechanisms are broken down into elementary steps. For each step the the reactants are directly involved in forming the transition state. Therefore a rate law can be written from an elementary step but not from an overall reaction. (09 Jan 1998) |
| alpha particle | <physics> A radioactive particle made up of two protons and two neutrons, these particles are created by the decay of a radioactive material or by nuclear bombardment, and they are the same as the nucleus of a helium-4 atom. (09 Oct 1997) |
| beta particle | <physics, radiobiology> An electron or positron emitted from a radioactive nucleus during beta decay. (09 Oct 1997) |
| genes, intracisternal a-particle | A family of retrovirus-like genetic elements coding for virus-like particles found regularly in early rodent embryos (2-cell to blastocyst stage), but which, under certain circumstances such as DNA hypomethylation, are transcribed in a wide variety of neoplasms, including plasmacytomas, neuroblastomas, rhabdomyosarcomas, teratocarcinomas, and colon carcinomas. (12 Dec 1998) |
| particle | <chemistry> A tiny mass of material. Origin: L. Particula, dim. Of pars = part (18 Nov 1997) |
| particle accelerators | Devices which accelerate electrically charged atomic or subatomic particles, such as electrons, protons or ions, to high velocities so they have high kinetic energy. (12 Dec 1998) |
| particle fluence | <chemistry, radiobiology> at a given point in space, the sum of energies, the number of particles or photons incident during a given time interval on a small sphere centreed at that point, divided by the cross-sectional area of that sphere. It is identical with the time integral of the particle flux density. (16 Dec 1997) |
| charged particle | <radiobiology> A particle which carries a positive or negative electrical charge. In plasma physics, this typically means an ionised atom or molecule, or an electron. (09 Oct 1997) |
| core particle | The group of eight histones (protein molecules which act like spools for DNA to wrap around so that it can be compacted to fit within the nucleus) in the middle of a nucleosome (which is the histone core particle plus the small segment of DNA wrapped around it). (09 Oct 1997) |
| proteinaceous infectious particle | A proposed pathogen composedonly of protein with no detectable nucleic acid and which is responsible for Creutzfeldt-Jakob disease and kuru inhumans and scrapie in sheep. (09 Oct 1997) |
| high energy particle generating unit | A machine capable of providing highly energised radiation for the purposes of radiotherapy treatment. (16 Dec 1997) |
| signal recognition particle | A complex between a 7S RNA and six proteins. SRP binds to the nascent polypeptide chain of eukaryotic proteins with a signal sequence and halts further translation until the ribosome becomes associated with the rough endoplasmic reticulum. One of the SRP proteins (srp54) binds GTP and in association with 7SRNA and srp19 has GTPase activity. (18 Nov 1997) |

| elementary particle |
In particle physics, an elementary particle is a particle of which other, larger particles are composed. For example, atoms are made up of smaller particles known as electrons, protons, and neutrons. The proton and neutron, in turn, are composed of more elementary particles known as quarks. ...

| elementary particle |
Indivisible unit from which all matter is made and forces are communicated. Currently known elementary matter particles are grouped into categories of quarks and leptons and their anti-matter counterparts. These particles interact through fundamental force carrier particles, which include the gluon, photon, and W and Z particles, and the theorized-but-undiscovered graviton.

| elementary particle |
Smallest unit of matter created in the big bang. Most of this matter decayed or was transformed within fractions of a second after the creation of the universe. (These particles can nowadays be created and investigated in high-energy accelerators.) From the few stable particles to survive the birth of the universe, two quarks and the electron make up the building blocks of the atoms. ...
