They are preoccupied riding herd on control panels, switches, flashing colored lights on pale green or gray consoles that look like business machines.

They are supplied, a batch at a time, by a secret source and are continually changed by Wisman or his staff, at random intervals.

They are mere fragments, just one portion of preprepared messages.

They are huge areas which have been swept by winds for so many centuries that there is no soil left, but only deep bare ridges fifty or sixty yards apart with ravines between them thirty or forty feet deep and the only thing that moves is a scuttling layer of sand.

They recognized that slavery was a moral issue and not merely an economic interest, and that to recognize it explicitly in their Constitution would be in explosive contradiction to the concept of sovereignty they had set forth in the Declaration of 1776 that `` all men are created equal, that they are endowed by their Creator with certain unalienable rights, that among them are life, liberty and the pursuit of happiness.

They are in general those fears that once seemed to have been amenable to prayer or ritual.

They are non-conformists on principle.

They are full of contempt for the institution of matrimony.

They feel they are leagued against a hostile, persecutory world, faced with the concerted malevolent opposition of squares and their hirelings, the police.

They for their part are convinced that Holmes is too `` unorthodox '' and `` theoretical '' to make a good detective.

They are presumed to have plunged to a common grave in this fatal embrace.

They are determined to prove something.

They tell us, sir, that we are free, because we have in one hand a ballot, and in the other a stock certificate.

They are very small, and in the form of haystacks, without either chimney or windows.

They are situated in the midst of trees, which hang over them, and appear truly romantick.

On December 21, the day that the Irish House of Commons petitioned for removal of Sir Constantine Phipps, their Tory Lord Chancellor, Molesworth reportedly made this remark on the defense of Phipps by Convocation: `` They that have turned the world upside down, are come hither also ''.

Defoe then commented, `` If they Could Draw that young Gentleman into Their Measures They would show themselves quickly, for they are not asham'd to Say They want only a head to Make a beginning ''.

They emerged as interchangeable cogs in a faulty but formidable machine: shaved nearly naked, hair queued, greatcoated, jackbooted, and best of all -- in the opinion of the British professional, Major Semple-Lisle -- `` their minds are not estranged from the paths of obedience by those smatterings of knowledge which only serve to lead to insubordination and mutiny ''.

They are longing to see you ''.

They are not true because scientists or prophets say they are true.

They work by chemically modifying a cell's DNA.

They are stable at high temperatures and pressures and may remain chemically unchanged during the metamorphic process.

They have high dielectric constants, very high thermal conductivity, high flash points ( from 170 to 380 ° C ) and are chemically fairly inert, being extremely resistant to oxidation, reduction, addition, elimination, and electrophilic substitution.

They proposed the term to describe chemical signals from conspecifics that elicit innate behaviors soon after the German Biochemist Adolf Butenandt characterized the first such chemical, bombykol ( a chemically well-characterized pheromone released by the female silkworm to attract mates ).

They convert ( or chemically reduce ) the dissolved metal ions from one electrical state to another.

They are chemically sweetened squashes, usually sweetened with one or more of aspartame, acesulfame K, saccharin and sucralose.

They are extracted from rocks and sediment cores both physically, by wet sieving, often after ultrasonic treatment, and chemically, by using chemical digestion to remove the non-organic fraction.

They are also chemically stable, so that they are eliminated from the body slowly ( they can bioaccumulate to dangerous levels ), and they persist in the environment for a long time.

They are a major component of biological membranes and can be easily obtained from a variety of readily available sources such as egg yolk or soy beans from which they are mechanically extracted or chemically extracted using hexane.

They include numerous types of ion channels, some that are chemically gated and some that are voltage-gated.

They are chemically inert and have a relatively high density.

They can also dissolve and actively take part in physiological processes, for example, when hydroxylapatite, a material chemically similar to bone structure, can integrate and help bone grow into it.

They are broad spectrum inhibitors and are chemically diverse with different types characteristic of particular plant species.

They are refractory, with high melting point and are chemically stable.

They may also chemically react with one another, producing new substances with new risks.

They are chemically nonreactive, so will not discolor or change the taste of food.

They are very stable chemically, thermally, and mechanically, and biologically inert.

They also must be very hot before they break down into their simpler components, such molten salts are " chemically stable " when maintained well below their boiling points.

They may be cut, crushed or pulverized and chemically altered.

They differ from other chiral compounds in that they can be equilibrated thermally whereas in the other forms of chirality isomerization is usually only possible chemically.

They did not know that chemically, the heat changed the starch in the root to a fermentable sugar.

They are also extremely inert chemically and exhibit decreased strength at lower temperatures.
