Dewar (crater)

Dewar is a lunar crater that lies on the Moon's far side. Less than one crater diameter to the south-southwest is the crater Stratton. Vening Meinesz is a little over one crater diameter to the northwest. The slightly worn rim of this crater is roughly circular, with a small outward protrusion along the southern edge. The interior floor is marked by several small impacts along the eastern side.

Dewar lies on the south side of an anomalously low albedo (dark patch) of terrain on the far side of the moon.

Usage examples of "dewar".

Frozen embryosin liquid nitrogen were transported in a special stainless steel thermos lined with borosilicate glass called a dewar.

But when it gave out, the antihydrogen ice in the core would start to evaporate, react within the inner chamber walls, and evaporate more antihydrogen in a runaway reaction that would cause the dewar walls to fail from radiation damage.

Then the dewar would collapse instantly under the water pressure, causing all the remaining antihydrogen to be mixed with matter.

Also from New York were the Chromes and the Backhyssons and the Dennickers and Russel Betty and the Corrigans and the Kellehers and the Dewars and the Scullys and S.

It explains the theory, urged so persistently by Butler in his speech to the jury, that the crime was the work of an enemy of the Dewars, the outcome of some hidden spite, or obscure quarrel.

So the bodies were put into metal dewars filled with liquid nitrogen, frozen solid at cryogenic temperature while the lawyers argued and ran up their fees.

Thus the catacombs grew, row upon row of gleaming stainless steel dewars, each filled with liquid nitrogen, each holding a human body that one day might be revived.

There was one at each end of the long row of dewars, and although the area was dimly lit, the cameras fed into Selene's security office where they were monitored twenty-four hours a day.
