A carillon bell is a cast bronze cup-shaped bell whose partial tones are in such harmonious relationship to each other as to permit many such bells to be sounded together in varied chords with harmonious and concordant effect.

The flowers are each seated in a cup-shaped disk which is borne on the base of a scale which is itself attached to the rachis of the catkin.

The cup-shaped nest is made with grasses, leaves and other vegetation, bound together with mud.

A crucible is a cup-shaped piece of laboratory equipment used to contain chemical compounds when heated to extremely high temperatures.

The nest is a deep cup-shaped structure made of grasses held together with mud or sometimes manure in a tree fork up to 10 metres above the ground.

It is cup-shaped and composed of twigs, small roots, bark strips, moss, other plant material, cloth, paper, and feathers, with occasional mud added to the cup.

Nests are cup-shaped, usually constructed by the female, and often placed in a vertical fork of a tree or shrub ; many species are expert at adding moss, bark or lichen to the outside of the nest as camouflague, making it very difficult to spot ( even when it is in a seemingly prominent location ).

The fruit in some species ( particularly in the genera Ocotea and Oreodaphne ) is partly immersed or covered in a cup-shaped or deep thick cupule, which is formed from the tube of the calyx where the peduncle joins the fruit ; this gives the fruit an appearance similar to an acorn.

The Goldcrest's nest is a well-insulated cup-shaped structure built in three layers.

Related to micelle formation is the technologically important ability of detergent actives to congregate at oil - water interfaces in such a manner that the polar ( or ionized ) end of the molecule is directed towards the aqueous phase and the hydrocarbon chain towards the oily phase.

Little is known of the synthetic mechanisms for formation of thyroglobulin.

A study of their activity on thyroglobulin has shown that thyroxine is not preferentially released and that the degradation proceeds stepwise with the formation of macromolecular intermediates ( Alpers, Petermann and Rall, 1956 ).

This warns the chartist that the formation in progress is quite likely to be a top.

( Pp. 228-229 ) in any event, it is obvious that the anti-trust laws did not prevent the formation of some of the greatest financial empires the world has ever known, held together by some of the most fantastic ideas, all based on the fundamental notion that a corporation is an individual who can trade and exchange goods without control by the government ''.

Scientists assume that cholesterol ( from the Greek chole, meaning bile, and sterios, meaning solid ) is somehow necessary for the formation of brain cells, since it accounts for about 2% of the brain's total solid weight.

In simultaneous microsporogenesis, there is no wall formation until all four cell nuclei are present.

It is not concerned with the formation of molecules ( although much of the physics is identical ), nor does it examine atoms in a solid state as condensed matter.

In quantum mechanics, where all particle momenta are associated with waves, it is the formation of such a wave packet which localizes the wave, and thus the particle, in space.

Another example is the formation of hypusine in the translation initiation factor EIF5A, through modification of a lysine residue.

Immediately below this formation is the Bearpaw Shale, a marine formation representing a section of the Western Interior Seaway.

In the formation of an ordinary agate, it is probable that waters containing silica in solution — derived, perhaps, from the decomposition of some of the silicates in the lava itself — percolated through the rock and deposited a siliceous coating on the interior of the vapour-vesicles.

Cytochrome c is also released from mitochondria due to formation of a channel, the mitochondrial apoptosis-induced channel ( MAC ), in the outer mitochondrial membrane, and serves a regulatory function as it precedes morphological change associated with apoptosis.

The universal aqueous acid – base definition of the Arrhenius concept is described as the formation of water from a proton and hydroxide ions, or hydrogen ions and hydroxide ions from the dissociation of an acid and base in aqueous solution:

A standard solution to this problem is found in Zermelo's set theory, which does not allow the unrestricted formation of sets from arbitrary properties.

The movie is also credited as one of the events that inspired the formation of the " second era " Ku Klux Klan at Stone Mountain, Georgia in the same year.

The precise formation mechanism is not known for certain, but the most widely accepted hypothesis suggests that the edge of the Cathedral Formation reef became detached from the rest of the reef, slumping and being transported some distance — perhaps kilometers — away from the reef edge.
