| interstitial growth | Growth from a number of different centres within an area; in contrast with appositional growth, it can occur only when the materials involved are nonrigid. (05 Mar 2000) |
|---|---|
| intrauterine growth retardation | <radiology> Definition: less than 10th percentile for gestational age, usually not detectable before 32-34 weeks (maximal foetal growth), incidence: 3-7% of all deliveries, 12-47% of twin pregnancies complications: increased risk for perinatal asphysia, meconium aspiration, electrolyte imbalance from metabolic acidosis, polycythemia, 6-8 fold increase for intrapartum and neonatal death see also: IUGR: aetiology, IUGR: phenotypes, foetal doppler study, biophysical profile (12 Dec 1998) |
| intussusceptive growth | Growth by increase in the size of component cells. Synonym: intussusceptive growth. (05 Mar 2000) |
| old growth | Timber stands with the following characteristics: large mature and over-mature trees in the overstory, snags, dead and decaying logs on the ground, and a multi-layered canopy with trees of several age classes. (05 Dec 1998) |
| old-growth stand | Forest stand dominated by trees reaching natural death, the last stage in forest succession. (09 Oct 1997) |
| Tanner growth chart | A series of chart's showing distribution of parameters of physical development, such as stature, growth curves, and skinfold thickness, for children by sex, age, and stages of puberty. (05 Mar 2000) |
| transforming growth factors | <chemical> Hormonally active polypeptides that can induce the transformed phenotype when added to normal, non-transformed cells. They have been found in culture fluids from retrovirally transformed cells and in tumour-derived cells as well as in non-neoplastic sources. Their transforming activities are due to the simultaneous action of two otherwise unrelated factors, transforming growth factor alpha and transforming growth factor beta. Chemical name: Animal growth regulators, transforming growth factors (12 Dec 1998) |
| endothelial growth factors | These growth factors are soluble mitogens secreted by a variety of organs. The factors are a mixture of two single chain polypeptides which have affinity to heparin. Their molecular weight are organ and species dependent. They have mitogenic and chemotactic effects and can stimulate endothelial cells to grow and synthesise DNA. The factors are related to both the basic and acidic fibroblast growth factors but have different amino acid sequences. (12 Dec 1998) |
| excess annual growth | The amount by which new forest growth exceeds removal in a year. The annual quantity of wood produced in a forest in excess of market demand. (05 Dec 1998) |
| exponential growth | <biology> A rate of growth of an organism, a part of an organism, or a population of organisms which, when graphed, produces an exponential or logarithmic curve. Such a rate occurs, for example: during the exponential growth phase, when a population of bacterial (or other) cells divide at a constant rate so that the total number of cells doubles with each division. (09 Oct 1997) |
| urban growth boundary | A land use boundary surrounding a city. Urban land uses are permitted within the urban growth boundary. (05 Dec 1998) |
| foetal growth retardation | The failure of a foetus to maintain its expected growth potential at any gestational stage. (12 Dec 1998) |
| abstracting and indexing | Shortening or summarizing of documents; assigning of descriptors for referencing documents. (12 Dec 1998) |
| academies and institutes | Organizations representing specialised fields which are accepted as authoritative; may be non-governmental, university or an independent research organization, e.g., national academy of sciences, brookings institution, etc. (12 Dec 1998) |
| accounts payable and receivable | Short-term debt obligations and assets occurring in the regular course of operational transactions. (12 Dec 1998) |
