| bag net | A bag-shaped net for catching fish. Source: Websters Dictionary (01 Mar 1998) |
| 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) |
| net flux | The difference between the two unidirectional flux's. (05 Mar 2000) |
| net heating value | The potential energy available in the fuel as received, taking into account the energy loss in evapourating and superheating the water in the sample. Expressed as NVH = (HHV x (1- MC / 100)) - (LH(2)O x MC / 100) (05 Dec 1998) |
| net knot | <cell biology> The central portion of a cells nucleus that typically contains a glob of heterochromatin. Origin: Gr. Soma = body (09 Oct 1997) |
| net present value | The sum of the costs and benefits of a project or activity. Future benefits and costs are discounted to account for interest costs. (05 Dec 1998) |
| net-veined | Having veins, or nerves, reticulated or netted; as, a net-veined wing or leaf. Source: Websters Dictionary (01 Mar 1998) |
| absorption | The process of absorbing, specifically: 1. <physiology> The movement and uptake of substances (liquids and solutes) into cells or across tissues such as skin, intestine and kiidney tubules, by way of diffusion or osmosis. 2. <chemistry> The drawing of a gas or liquid into the pores of a permeable solid. 3. <psychology> The devotion of thought to one object or activity, with inattention to others. 4. <radiology> The taking up of energy by matter with which the radiation interacts. 5. <physics> The loss of (electromagnetic) energy to a medium. For instance, an electromagnetic wave which propagates through a plasma will set the electrons into motion. If the electrons make collisions with other particles, they will absorb net energy from the wave. 6. <immunology> A process in which an antigen or antibody is used to pull an analogous antigen or antibody out of a solution. Compare: adsorption. Origin: L. Absorptio (12 Nov 1997) |
| absorption band | The range of wavelengths or frequencies in the electromagnetic spectrum where radiant energy is absorbed by passage through a gaseous, liquid, or dissolved substance; it is exploited for analytical purposes in colourimetry or spectrophotometry, and is usually described in terms of the wavelength where maximum absorbance occurs (i.e., lambdamax). (05 Mar 2000) |
| absorption cell | A small glass chamber with parallel sides, in which absorption spectra of solutions can be obtained. (05 Mar 2000) |
| absorption chromatography | <investigation> Techniques for separating molecules based on differential absorption and elution. Term for separation methods involving flow of a fluid carrier over a nonmobile absorbing phase. (18 Nov 1997) |
| net absorption |
the difference between uptake and efflux from a tissue or cell.
