| hybrid diode | <radiobiology> An ion diode that uses a field coil in series with the ion diode's accelerating gap to generate sufficient magnetic flux in the diode for electron control. The diode is a combination of the Applied-B diode's ion source and the Ampfion diode's field coil. (09 Oct 1997) |
|---|
| applied-b diode | <radiobiology> An ion diode with an applied magnetic field to prevent electrons flowing from cathode to anode. The applied magnetic field also regularizes the electron swarm to reduce beam divergence. (09 Oct 1997) |
|---|---|
| pinch reflex diode | <radiobiology> A self-insulated ion diode in which the magnetic field from the ion and electron flow alone provide electron control, and the ion source is an anode plasma formed by relexing the electrons through a thin plastic foil. (09 Oct 1997) |
| ion diode | <radiobiology> Device for producing and accelerating ion beams for light ion drivers for inertial confinement fusion. Ions are produced in an anode plasma, extracted as space-charge-limited ion flow, and accelerated to the cathode, composed of a confined electron swarm, by an applied electric field. Millions of amperes of current at millions of volts have been produced this way. (27 Oct 1998) |
| computers, hybrid | Computers that combine the functions of analog and digital computers. (12 Dec 1998) |
| hybrid | <biology> An offspring of parents from different species or sub-species. (09 Oct 1997) |
| hybrid antibody | <immunology> Artificially produced antibody made by fusing hybridomas producing two different antibodies, the hybrid cells produce three different antibodies, only one of which is a heterophilic antibody. Can also be prepared chemically from two antibodies. (18 Nov 1997) |
| hybrid-arrested translation | <molecular biology> The prevention of an mRNA molecule from being translated into a protein by hybridising it to its corresponding cDNA or to a complementary mRNA. This is used to identify cDNA molecules - the scientist puts the cDNA molecule in question in a test tube with a number of mRNA molecules and observes which protein is no longer able to be made. (09 Oct 1997) |
| hybrid cell | <genetics, molecular biology> Any cell type containing components from one or more genomes, other than zygotes and their derivatives. Hybrid cells may be formed by cell fusion or by transfection. See: heterokaryon. (18 Nov 1997) |
| hybrid DNA | <molecular biology> A double-stranded DNA molecule which was made by hybridising two single-stranded DNA molecules from two different sources. If the two single-stranded DNA molecules have enough nucleotide sequences in common, they are able to form hydrogen bonds to each other's common sequences. (09 Oct 1997) |
| hybrid dysgenesis | The inability of certain strains of the fruit fly Drosophila melanogaster to interbreed with each other because they produce offspring that are all sterile or offspring which have a high number of harmful mutations. (09 Oct 1997) |
| hybrid enzyme | <biochemistry> An enzyme in a heterozygous individual which has subunits with slightly different sequences of amino acids than other copies of the same enzyme. This occurs because the two alleles of the genes which code for each subunit are slightly different (due to the heterozygosity), so that either of the two versions of the subunit could be produced for any copy of the enzyme. (09 Oct 1997) |
| hybrid inviability | <biology> The observation that certain hybrid organisms have lower fitness than the parent organisms, for example they grow more poorly or have lower survival rates. Hybrid inviability is the opposite of hybrid vigor. (09 Oct 1997) |
| hybrid molecule | <molecular biology> A double-stranded nucleic acid molecule which was artificially created from two different single-stranded nucleic acid molecules from different sources, for the purpose of comparing their nucleotide sequences. (09 Oct 1997) |
| hybrid name | <zoology> Names given to hybrids are not normally available, as they are individuals, not populations, and hence not taxa. (09 Jan 1998) |
| hybrid plasmid | <molecular biology> A plasmid (circular DNA molecule) which is composed partly of the DNA of an organisms (or virus's) genome and partly of foreign DNA that has been inserted artificially. (09 Oct 1997) |
