| double refraction | <microscopy> The refraction of light in two slightly different directions to form two rays or vector components. Each ray is polarized, and their vibration directions are perpendicular to each other. Furthermore, each ray has a different velocity, and therefore a different refractive index. See: birefringence.

| double thymidine block | <cell culture, procedure> A lab technique used to synchronise the cell cycles of all the cells in a culture. This is done by adding excessive amounts of thymidine (a deoxynucleoside) to the culture so that DNA replication is blocked. Eventually, all of the cells will reach the same point in the cell cycle and stop. (09 Oct 1997) |

| double-blind | <statistics> A kind of clinical study in which neither the participants nor the person administering treatment know which treatment any particular subject is receiving. Usually the comparison is between an experimental drug and a placebo or standard comparison treatment. This method is believed to achieve the most accuracy because neither the doctor nor the patient can affect the observed results with their psychological bias. (10 Oct 1997) |
| double-blind experiment | <statistics> An experiment conducted with neither experimenter nor subjects knowing which experiment is the control; prevents bias in recording results. See: double-masked experiment. (05 Mar 2000) |
| double-blind method | <statistics> A method of studying a drug or procedure in which both the subjects and investigators are kept unaware of who is actually getting which specific treatment. (12 Dec 1998) |
| double-blind study | A study in which neither the experimenter nor any other assessor of the results, including patients, know which group is subject to which procedure, thus helping assure that the biases or expectations of either will not influence the results. (05 Mar 2000) |

| double depression |
Dysthymia, or dysthymic disorder, is a form of the mood disorder of depression characterised by a lack of enjoyment/pleasure in life that continues for at least six months. It differs from clinical depression in the severity of the symptoms. While dysthymia usually does not prevent a person from functioning, it prevents full enjoyment of life. Dysthymia also lasts much longer than an episode of major depression. ...

| double refraction |
Birefringence, or double refraction, is the division of a ray of light into two rays (the ordinary ray and the extraordinary ray) when it passes through certain types of material, such as calcite crystals, depending on the polarization of the light. This is explained by assigning two different refractive indices to the material for different polarizations. ...

| doublet |
A doublet is a man's snug-fitting buttoned jacket that was worn in medieval and Tudor times. Originally it was a mere stitched and quilted lining ("doubling"), worn under a hauberk or cuirass to prevent bruising and chafing. Then, like many other originally practical items in the history of men's wear, from the late 15th century onward it became elaborated enough to be seen on its own. ...

| doublet |
A doublet is one of two or more words of the same language that come from the same root. Doublets may be nearly synonymous, for example English pyre and fire; may have fairly different meanings, for example aperture and overture (the commonality behind the meanings is "opening"); or may even develop meanings that are in a sense opposites, for example host and guest. Doublets also vary with respect to how far their forms have diverged. ...
