| intensive care unit | A hospital facility for provision of intensive nursing and medical care of critically ill patients, characterised by high quality and quantity of continuous nursing and medical supervision and by use of sophisticated monitoring and resuscitative equipment; may be organised for the care of specific patient groups, e.g., neonatal or newborn ICU, neurological ICU, pulmonary ICU. Synonym: critical care unit. (05 Mar 2000) |

| intensive care units | Hospital units providing continuous surveillance and care to acutely ill patients. (12 Dec 1998) |
| intensive care units, neonatal | Hospital units providing continuing surveillance and care to acutely ill newborn infants. (12 Dec 1998) |
| intensive care units, paediatric | Hospital units providing continuous surveillance and care to acutely ill infants and children. Neonates are excluded since intensive care units, neonatal is available. (12 Dec 1998) |
| intensive management | Planned, active treatment to improve the quality and quantity of timber within a stand. A general term that distinguishes active forest management from passive forest management. (05 Dec 1998) |
| intensive properties | <chemistry> Properties which are independent of the amount of the substance. (09 Jan 1998) |
| intensive psychotherapy | Psychotherapy involving thorough exploration of the patient's life history, conflicts, and related psychodynamics; often contrasted with supportive psychotherapy. (05 Mar 2000) |
| ionic strength | Symbolised as g/2 or I and set equal to 0.5σmizi2, where mi equals the molar concentration and zi the charge of each ion present in solution; if molar concentrations (ci) are used instead of molality (and the solution is dilute), then I == 0.5(1/ρo)σcizi2 where ρo is the density of the solvent; a number of biochemically important events (e.g., protein solubility and rates of enzyme action) vary with the ionic strength of a solution.

| tensile strength | The maximum stress a material subjected to a stretching load can withstand without tearing. (12 Dec 1998) |
| yield strength | The amount of stress at which a permanent (plastic) deformation in a component becomes measurable (usually taken as 0.2% permanent strain). (05 Mar 2000) |
| ultimate strength | The maximum stress achieved prior to failure of a component on a single application of the load. (05 Mar 2000) |
| fatigue strength | The stress level below which a particular component will survive an indefinite number of load cycles (typically about 50% of the ultimate strength of the component). (05 Mar 2000) |
