The stones they used were the heavy stone weights from the weavers ' " warp beams ," fitted with a detachable handle for the purpose.

This evidence that the beams were composed of particles was strong because scientists knew it was impossible to deflect electromagnetic waves with an electric field.

The residents had used the marble columns and structures as support beams and roofs for their improvised houses, a usual way of rebuilding towns that were partially or totally destroyed, especially after the earthquake in 1580, which demolished several towns in Phocis.

The purpose of these slots is not known, but the central gutter in the floor of the Gallery, which is the same width as the Ascending Passage, has led to speculation that the blocking stones were stored in the Grand Gallery and the slots held wooden beams to restrain them from sliding down the passage.

As the planks reached the desired height, the interior frame ( futtocks ) and cross beams were added.

By 1948, the house's load-bearing exterior walls and internal wood beams were found to be close to failure.

Another type of ram was one that maintained the normal shape and structure, but the support beams were instead made of saplings that were lashed together.

Functioning tractor beams based on solenoidal modes of light were demonstrated in 2010 by physicists at New York University.

For several decades, cyclotrons were the best source of high-energy beams for nuclear physics experiments ; several cyclotrons are still in use for this type of research.

In France the condemned were placed on a cart-wheel with their limbs stretched out along the spokes over two sturdy wooden beams.

The turbine casing and concrete machine block surrounding it were destroyed in May 1990 when two steel beams entered the turbine.

Their beams were narrower than ocean-going Bermuda sloops, and they carried gaff rig, where Bermuda sloops might carry gaff or Bermuda rig.

When such stars transition to supernovas, they may emit intense beams of gamma rays, and if Earth were to lie in the beam zone, devastating effects may occur.

The carriages ran on two parallel concrete beams and were guided by pulleys running on the inner side of these concrete beams, and were propelled by gripping a revolving screw thread running between the tracks in a pit ; by adjusting the pitch of this thread at different points, the carriages could be sped up, or slowed down to a walking pace at stations, to allow passengers to join and leave.

Since the original design came from wooden temples and the triglyphs were real heads of wooden beams, every column had to bear a beam which lay across the centre of the column.

Subsequent inquiries into the matter showed that the beams were improperly manufactured, but the ban remained.

They would have failed to support the building, so collar beams and queen posts were added to the design in order to help prevent sagging.

The beams were hidden by a false ceiling, installed below the lantern stage of the tower.

On Jan. 20, while the craft was still in daylight, the TV camera clearly saw two laser beams aimed at it from the night side of the crescent Earth, one from Kitt Peak National Observatory, Tucson, Arizona, and the other at Table Mountain at Wrightwood, California.

* Lazerette-Cybron's only ( clearly ) female bio-borg, she can shoot laser beams from her eyes and mouth.

a pile of wire cages for mice from his time as a geneticist and a microscope lying on its side on the window sill, vertical steel columns wired for support to the open ceiling beams with spidery steel cantilevers jutting out into the air, masonry constructions on the floor from the time he was inventing his disastrous fireplace whose smoke would pass through a whole house, visible all the way up through wire gratings on each floor.

The three sides of the beams visible from the playing field must be painted alternatingly in two contrasting colors which both have to contrast against the background.

Science fiction movies and telecasts normally depict tractor and repulsor beams as audible, narrow rays of visible light that cover a small area of a target.

A dichroic material is either one which causes visible light to be split up into distinct beams of different wavelengths ( colours ) ( not to be confused with dispersion ), or one in which light rays having different polarizations are absorbed by different amounts.

c is a compensating plate so that both the reflected and transmitted beams travel through the same amount of glass ( important since experiments were run with white light which has an extremely short coherence length requiring precise matching of optical path lengths for fringes to be visible ; monochromatic sodium light was used only for initial alignment ).

Radiowaves, microwaves, infrared light, and visible light are normally considered non-ionizing radiation, although very high intensity beams of these radiations can produce sufficient heat to exhibit some similar properties to ionizing radiation, by altering chemical bonds and removing electrons from atoms.

The jets are believed to be the visible manifestations of the beams, and often the term jet is used to refer both to the observable feature and to the underlying flow.

But with dark background illumination and customized light beams, and without microscopes, very low concentrations of particulates very far below the threshold of visibility become visible and quantifiable because of light scattering.

Mies would have preferred the steel frame to be visible to all ; however, American building codes required that all structural steel be covered in a fireproof material, usually concrete, because improperly protected steel columns or beams may soften and fail in confined fires.

They are widely used in laboratory demonstrations in the field of optics in view of their relatively low cost and ease of operation compared to other visible lasers producing beams of similar quality in terms of spatial coherence ( a single mode gaussian beam ) and long coherence length ( however since about 1990 semiconductor lasers have offered a lower cost alternative for many such applications ).

Acting Ensign Wesley Crusher suggests sending a neutrino pulse device to the planet in a probe ; the neutrino beams will be visible to La Forge's VISOR.

Beam tracing is a ray-tracing approach which divides the visible volumes into beams.

Its exterior is partly of brick and partly tile-hung, the roof is tiled, and substantial wooden beams and trusses are visible inside.

Both beams recombine at point C ' to produce an interference pattern ( assuming proper alignment ) visible to the observer at point E. To the observer at point E, the effects observed would be the same as those produced by placing surfaces A and B ' ( the image of B on the surface M ) on top of each other.

The original wooden beams and davitts, which became bar posts, are still visible today.

The house itself is unusual in its construction: most properties of the period were built, using a wooden frame with wattle and daub infill, or with a brick infill, so that the wooden beams would be visible from the outside as well as from inside the property.

Whereas smoke screens would originally have been used to hide movement from enemies ' line of sight, modern technology means that they are now also available in new forms ; they can screen in the infrared as well as visible spectrum of light to prevent detection by infrared sensors or viewers, and also available for vehicles is a superdense form used to prevent laser beams of enemy target designators or range finders on vehicles.

Although no upper floors remain, the cuts for support beams are visible in the stone walls and illustrate construction methods of the era.

Photoelectric beam systems detect the presence of an intruder by transmitting visible or infrared light beams across an area, where these beams may be obstructed.

Because the IR-laser component in the beams of these visible lasers is difficult to filter out, and also because filtering it contributes extra heat which is difficult to dissipate in a small pocket " laser pointer " package, it is often left as a beam component in cheaper high-power pointers.

Later experimenters painted the back wall of Crookes tubes with fluorescent paint, to make the beams more visible.

The electron beams are visible as fine bluish lines.
