While Proteus is usually thought to contain significant amounts of water ice, it has not been detected spectroscopically on the surface.

The surface of Proteus shows several flat or slightly concave facets measuring from 150 to 200 km in diameter.

Pharos is the only named surface feature on this moon: the name is Greek and refers to the island where Proteus reigned.

Weil and Felix studying Proteus bacilli observed that the flagellated strains growing on agar formed a thin surface film resembling the mist produced by breathing on glass and named this variety the Hauch.

The surface of Proteus is heavily cratered and shows a number of linear features.

the mill-pond is quiet, its surface dark and shadowed, and there does not seem to be much water in it.

It appears that the dominant tendency of Mann's early tales, however pictorial or even picturesque the surface, is already toward the symbolic, the emblematic, the expressionistic.

If many of the characters in contemporary novels appear to be the bloodless relations of characters in a case history it is because the novelist is often forgetful today that those things that we call character manifest themselves in surface behavior, that the ego is still the executive agency of personality, and that all we know of personality must be discerned through the ego.

The brush moves up and down and is small enough to clean every dental surface, including the back of the teeth.

In view of the increasing shortage of usable surface and ground water in many parts of the Nation and the importance of finding new sources of supply to meet its present and future water needs, it is the policy of the Congress to provide for the development of practicable low-cost means for the large-scale production of water of a quality suitable for municipal, industrial, agricultural, and other beneficial consumptive uses from saline water, and for studies and research related thereto.

This shelter could be built in regions where water or rock is close to the surface, making it impractical to build an underground shelter.

These are particularly suitable for regions where water or rock is close to the surface.

A Barrette Swiss pattern file is handy since its triangular shape with only one cutting face will allow you to work a surface without marring an adjoining one.

To measure the volume of one of the combustion chambers in the cylinder head, install the valves and spark plug in the chamber and support the head so that its gasket surface is level.

This is possible with water and other liquids that have a high surface tension.

This is done by measuring the distance from the surface on which the tire is resting to the center of the rear axle shaft.

This result suggests a very high temperature at the solid surface of the planet, although there is the possibility that the observed radiation may be a combination of both thermal and non-thermal components and that the observed spectrum is that of a black body merely by coincidence.

The infrared emission could then be assumed to originate at the surface of the moon, while the radio emission originates at some depth beneath the surface, where the temperature variation due to solar radiation is reduced in amplitude and shifted in phase.

The constant-temperature contours are much smoother than those observed at 4.3 mm by Coates ( 1959 ) and apparently the emission at 8 mm is not nearly so sensitive to differences in surface features.

The mean temperature of the surface was then computed according to the following relation: Af where x is the fraction of the plug area covered by the hot spot.

It is sufficiently small compared with the surface temperature of the anode holder, to make the energy flux radiated from the environment toward the anode holder negligible within the accuracy of the present measurements.

The radiation loss from the anode surface was computed according to Af where Af is the mean of the fourth powers of the temperatures Af and Af calculated analogously to equation ( 1 ).

The relative forces can be calculated from the various radii of curvature if we assume: ( A ) The surface tension is uniform on the surface of the drop.

Just as the pressure exerted by surface tension in a spherical drop is Af and the pressure exerted by surface tension on a cylindrical shape is Af, the pressure exerted by any curved surface is Af, where **yg is the interfacial tension and Af and Af are the two radii of curvature.

As he ranged his belongings on the bureau he noticed a film of white dust on the dark surface of the wood beyond the linen cover.

The coffin stood on trestles in a corner of the long low dimly lit funeral parlor, on its dark shining surface the sheaf of white roses I had ordered.

A similar effect can be achieved by drawing different tones close together ; a light edge next to a dark background will stand out to the eye, and almost appear to float above the surface.

Low surface brightness dwarf galaxies are important sources of information for studying dark matter, as they have an uncommonly low ratio of visible matter to dark matter, and have few bright stars at the center which would otherwise impair observations of the rotation curve of outlying stars.

Acid etching darkens the 1080 plain carbon steel more than it does the 15N20 alloy steel | low alloy nickel steel, producing alternating bands of light and dark on the surface.

It was used to determine the absolute temperature of Venus ' surface and details concerning its atmosphere through its microwave-radiation characteristics, including the daylight and dark hemispheres, and in the region of the terminator.

Their approach pictures did, however, photograph about 20 percent of the planet's surface, showing the dark features long seen from Earth, but none of the canals mistakenly observed by ground-based astronomers.

For practical applications, gratings generally have ridges or rulings on their surface rather than dark lines.

New Zealand's fjords are also host to deep sea corals, but a surface layer of dark fresh water allows these corals to grow in much shallower water than usual.

There is little water current in such environments, so oxygen from surface water is not brought down, and the deposited sediment is normally a fine dark clay.

The Metidian surface is heavily cratered, dark, and appears to be reddish in color.

An operational, non-fictional cloaking device might be an extension of the basic technologies used by stealth aircraft, such as radar-absorbing dark paint, optical camouflage, cooling the outer surface to minimize electromagnetic emissions ( usually infrared ), or other techniques to minimize other EM emissions, and to minimize particle emissions from the object.

This suggested only 10 % of Halley's surface was active, and that large portions of it were coated in a layer of dark dust, which retained heat.

The drow are well adapted to seeing in the dark, and they loathe, are terrified of, and are easily blinded by the light of the surface.

It is a primitive C-type asteroid, which means the surface has a high proportion of carbon ; giving it a dark surface that reflects only 4 % of the light that falls on it.

In older printers, a corona wire positioned parallel to the drum, or in more recent printers, a primary charge roller, projects an electrostatic charge onto the photoreceptor ( otherwise named the photo conductor unit ), a revolving photosensitive drum or belt, which is capable of holding an electrostatic charge on its surface while it is in the dark.

They are generally dark on the upper surface, ranging from black to greyish-blue and brown, with pale undersides ; individuals have a unique pattern of blotches and scars that can be used to identify them.

It has a dark, heavily cratered surface, which shows spectral signs of water ice.

File: Martian Dust Devil Trails. jpg | Martian dust devils cause twisting dark trails on the Martian surface.

The playable surface consists of using only the dark squares of a board with alternating light and dark squares.

Ugly dark blotches mottled the dull orange surface and great columns of spinning flame arced around the rim .... < nowiki > watched </ nowiki > the titan sunspots drift slowly across the hideous disc, at times growing larger and merging into great gaping chasms in the fiery atmosphere, while at others dwindling almost to nothingness .... Something was stirring deep within that fiery atmosphere ; something monstrous that roared an insatiable anger against the chains of the Elder Gods which had bound it there for an eternity ....
