| low aspect ratio | <physics> An aspect ratio for a torus that is small (minor radius is almost as big as major radius). There are many fusion devices which are designed to have a low aspect ratio. Such devices look more like tractor tires than bicycle tires, as toruses go. There are reasons to believe that low aspect ratio devices will offer some advantages for a fusion reactor. Usually, ease of theoretical and/or numerical analysis is not one of these advantages. (16 Mar 1998) |

| 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) |

| aspect | 1. The act of looking; vision; gaze; glance. "The basilisk killeth by aspect." "His aspect was bent on the ground." (Sir W. Scott) 2. Look, or particular appearance of the face; countenance; mien; air. "Serious in aspect." "[Craggs] with aspect open shall erect his head." (Pope) 3. Appearance to the eye or the mind; look; view. "The aspect of affairs." "The true aspect of a world lying in its rubbish." (T. Burnet) 4. Position or situation with regard to seeing; that position which enables one to look in a particular direction; position in relation to the points of the compass; as, a house has a southern aspect, that is, a position which faces the south. 5. Prospect; outlook. "This town affords a good aspect toward the hill from whence we descended." (Evelyn) 6. <astronomy> The situation of planets or stars with respect to one another, or the angle formed by the rays of light proceeding from them and meeting at the eye; the joint look of planets or stars upon each other or upon the earth. The aspects which two planets can assume are five; sextile, when the planets are 60 deg apart; quartile, or quadrate, when their distance is 90 deg or the quarter of a circle; trine, when the distance is 120 deg; opposition, when the distance is 180 deg, or half a circle; and conjunction, when they are in the same degree. Astrology taught that the aspects of the planets exerted an influence on human affairs, in some situations for good and in others for evil. 7. <astronomy> The influence of the stars for good or evil; as, an ill aspect. "The astrologers call the evil influences of the stars evil aspects. <geometry>" Aspect of a plane, the direction of the plane. Origin: L. Aspectus, fr. Aspicere, aspectum, to look at; ad + spicere, specere, to look, akin to E. Spy. Source: Websters Dictionary (01 Mar 1998) |
| back pain, low | Symptoms in the low back can relate to the bony lumbar spine, discs between the vertebrae, ligaments around the spine and discs, spinal cord and nerves, muscles of the low back, internal organs of the pelvis and abdomen, and the skin covering the lumbar area. The low back, or lumbar area, functions in structural support, movement, and protection of certain body tissue. (12 Dec 1998) |
| blood sugar, low | The sugar here is glucose. Low blood glucose constitutes hypoglycaemia. Hypoglycaemia is only significant when it is associated with symptoms. It has many causes including drugs, liver disease, surgical absence of the stomach, pre-diabetes, and rare tumours that release excess insulin. (12 Dec 1998) |
| cardiac output, low | A state of subnormal or depressed cardiac output, usually seen in patients with heart failure secondary to coronary artery, hypertensive, primary myocardial, valvular, or pericardial disease. (12 Dec 1998) |
| very low density lipoprotein | <biochemistry> A lipoprotein substances (combination of a fat and a protein) which acts as a carrier for cholesterol and fats (particularly triglycerides) in the bloodstream. Elevations in very low density lipoprotein in the bloodstream are associated with an increased risk of atherosclerosis and coronary artery disease. Acronym: VLDL (18 Nov 1997) |
| Castellani-Low sign | <clinical sign> A fine tremor of the tongue observed in sleeping sickness. (05 Mar 2000) |
| mean lower low water | <marine biology> The average height of the lower low waters over a 19-year period. For shorter periods of observations, corrections are applied to eliminate known variations and reduce the result to the equivalent of a mean 19-year value. (09 Oct 1997) |
| mean low water | <marine biology> The average height of the low waters over a 19-year period. For shorter periods of observations, corrections are applied to eliminate known variations and reduce the result to the equivalent of a mean 19-year value. All low-water heights are included in the average where the type of tide is either semidiurnal or mixed. Only the lower low-water heights are included in the average where the type of tide is diurnal. So determined, mean low water in the latter case is the same as mean lower low water. (09 Oct 1997) |
| placenta, low | Location of the placenta in the lower part of the uterus (womb) so that the placenta partially or completely covers the cervix. Also known as a placenta previa. (12 Dec 1998) |
| heparin, low-molecular-weight | <chemical> Heparin fractions with a molecular weight usually between 4000 and 6000 kD. These low-molecular-weight fractions are effective antithrombotic agents. Their administration reduces the risk of haemorrhage, they have a longer half-life, and their platelet interactions are reduced in comparison to unfractionated heparin. They also provide an effective prophylaxis against postoperative major pulmonary embolism. Pharmacological action: anticoagulant, fibrinolytic agent. (12 Dec 1998) |
| infant, low birth weight | An infant having a birth weight of 2500 gm. (5.5 lb.) or less but infant, very low birth weight is available for infants having a birth weight of 1500 grams (3.3 lb.) or less. (12 Dec 1998) |
| infant, very low birth weight | An infant having a birth weight of 1500 grams (3.3 lb.) or less. (12 Dec 1998) |
| ear, low-set | A minor anomaly involving an ear situated down below its normal location. Technically, the ear is low-set when the helix (of the ear) meets the cranium at a level below that of a horizontal plane through both inner canthi (the inside corners of the eyes). The presence of 2 or more minor anomalies in a child increases the probability that the child has a major malformation. (12 Dec 1998) |
| kininogen, low-molecular-weight | A protein, molecular weight 50 kD, located in various normal tissues. Upon cleavage by kallikrein or other kallikreins, it forms kallidin. Kallidin, in turn, is converted into bradykinin. (12 Dec 1998) |
