| Chiari's net | Abnormal fibrous or lacelike strands in the right atrium, extending from the margins of the coronary or caval valves and attaching to the atrial wall along the line of the crista terminalis; results when resorption of the septum spurium is markedly less than normal. (05 Mar 2000) |
| chromidial net | A reticulum of basophilic-staining material in the cytoplasm of certain cells. (05 Mar 2000) |
| nerve net | A meshlike structure composed of interconnecting nerve cells that are separated at the synaptic junction or joined to one another by cytoplasmic processes. In invertebrates, for example, the nerve net allows nerve impulses to spread over a wide area of the net because synapses can pass information in any direction. (12 Dec 1998) |
| net | 1. To make into a net; to make n the style of network; as, to net silk. 2. To take in a net; to capture by stratagem or wile. "And now I am here, netted and in the toils." (Sir W. Scott) 3. To inclose or cover with a net; as, to net a tree. Origin: Netted; Netting. Source: Websters Dictionary (01 Mar 1998) |

| acetyl value | The milligrams of KOH required to neutralise the acetic acid produced by the hydrolysis of 1 g of acetylated fat; a measure of the hydroxy acids present in glycerides; notably high in castor oil. (05 Mar 2000) |
| beta, or beta-value | <radiobiology> Ratio of plasma kinetic pressure to magnetic-field pressure, proportional to the ratio of plasma kinetic energy density to magnetic field energy density. Beta is usually measured relative to the total, local field (loosely called beta toroidal), but sometimes the plasma pressure relative to only the poloidal component of the field (beta poloidal) or relative to some external field (like the maximum field at the magnetic coils) is more useful. There is also a normalised beta (beta_N) of interest when discussing the beta limit. (lots of help from Art Carlson with the above.) Because the cost of a reactor is strongly influenced by the strength of the magnetic field that must be provided, beta values are directly related to the economics of fusion power production. Beta is usually expressed as a percentage, with 5% generally believed to be the minimum value required for an economical fusion reactor. See: pressure, kinetic pressure, magnetic pressure, second stability. (09 Oct 1997) |
| biological value | <nutrition> The nutritional value of a protein, usually measured in comparison to the nutritional value of egg protein, which is the highest possible (BV=0.9 - 1.00). (21 Mar 1998) |
