| Udden-Wentworth scale | <plant biology> A geometric scale of grain sizes which classifies particles of siliciclastic sediment from 4096 millimetres (boulders) in size down to 0.00006 millimetres (clay). This scale is almost universally accepted by modern sedimentologists (a type of geologist). It was first proposed in 1898 by Udden and then modified and extended in 1922 by Wentworth. (09 Oct 1997) |

| Kelvin scale | Temperature scale in which the triple point of water is assigned the value of 273.16 K; 캜 = K -273.15. (05 Mar 2000) |
| Zubrod scale | A 5-point scale similar to the 10-point Karnofsky scale; both measure the performance status of a patient's ambulatory nature, from normal activity to total dependence on others for care. See: Karnofsky scale. (05 Mar 2000) |
| French scale | A scale for grading sizes of sounds, tubules, and catheters as based on a measurement of 1/3 mm and equaling 1 fr on the scale (e.g., 3 fr = 1 mm); grading to scale is carried out using a metal plate with holes ranging from 1/3 mm to 1 cm in diameter. Synonym: Charriere scale. (05 Mar 2000) |
| Leiter International Performance Scale | A nonverbal (performance) test for measuring intelligence which contains norms for each age between 2 and 18; originally developed as a method of assessing the comparative intellectual abilities of Caucasian, Chinese, and Japanese children, but now occasionally used for assessing slow learners and those who are blind, deaf, or verbally handicapped. (05 Mar 2000) |
| Likert scale | A method of measuring attitudes that asks respondents to indicate their degree of agreement or disagreement with statements, according to a three-or five-point scoring system, e.g., "strongly agree" "no opinion" or "strongly disagree." (05 Mar 2000) |
| absolute terminal innervation ratio | The number of motor endplates divided by the number of terminal axons related to them. (05 Mar 2000) |
| accommodative convergence-accommodation ratio | The amount of convergence (measured in prism diopters of convergence) divided by the amount of accommodation (measured in diopters) required to direct both eyes upon an object. (05 Mar 2000) |
| A/G ratio | <abbreviation> Albumin-globulin ratio. (05 Mar 2000) |
| albumin-globulin ratio | The ratio of albumin to globulin in the serum or in the urine in kidney disease; the normal ratio in the serum is approximately 1.55. (05 Mar 2000) |
| ALT:AST ratio | The ratio of serum alanine aminotransferase to serum aspartate aminotransferase; elevated serum levels of both enzymes characterise hepatic disease; when both levels are abnormally elevated and the ALT:AST ratio is greater than 1.0, severe hepatic necrosis or alcoholic hepatic disease is likely; when the ratio is less than 1.0, an acute non-alcoholic hepatic condition is favoured. (05 Mar 2000) |
| amylase-creatinine clearance ratio | A test for the diagnosis of acute pancreatitis; it is determined by measuring amylase and creatinine in serum and urine in apparently healthy individuals the renal clearance of amylase is less than 5% that of creatinine; in acute pancreatitis the ratio is said to be greater than 0.05 or 5%. (05 Mar 2000) |
| aspect ratio | <radiobiology> In toroidal geometry, the ratio of the major diameter (total width of the torus) to the minor diameter (width of a slice taken through one side of the ring). In inertial-confinement fusion, aspect ratio refers to the ratio of a fuel pellet's radius to its wall thickness. (09 Oct 1997) |
| at/gc ratio | <molecular biology> The ratio of adenine-thymine base pairs to guanine-cytosine base pairs on a DNA molecule. (09 Oct 1997) |
| basic reproductive rate, ratio | <epidemiology> See Reproductive Ratio. (05 Dec 1998) |
