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 danced the paxam wildly at night, the war dance, and dipped their arrowheads in the venom of rattlesnakes and rode their horses in swift maneuvers, firing their few guns in unison at some indeterminate signal.

They had some signal instances to point to, especially from the long years of the Peloponnesian War.

They are known for their alarm signal: when startled or frightened, a swimming beaver will rapidly dive while forcefully slapping the water with its broad tail, audible over great distances above and below water.

They stated that the pre-and post-Madrid versions of Chapter 8 were equally cautious in their statements ; that roughly 20 % of Chapter 8 is devoted to the discussion of uncertainties in estimates of natural climate variability and the expected signal due to human activities ; and that both versions of the chapter reached the same conclusion: " Taken together, these results point towards a human influence on climate.

They were rescued after rebuilding a survival radio and using distress flares to signal for help.

They choose the domain in which to process a signal by making an informed guess ( or by trying different possibilities ) as to which domain best represents the essential characteristics of the signal.

They are used to stabilize the frequency of most radio transmitters, and to generate the clock signal in computers and quartz clocks.

They are controlled by the signal being mixed.

They have some kind of gain, or multiplication factor relating the magnitude of the output signal to the input signal.

They signal release of the nascent polypeptide from the ribosome because there is no cognate tRNA that has anticodons complementary to these stop signals, and so a release factor binds to the ribosome instead.

They always use the activation of adenylate cyclase as the next step in the signal chain.

They are activated in response to a conformation change in the G protein-coupled receptor, exchange GDP for GTP, and dissociate to activate other proteins in the signal transduction pathway.

They generally use individual piezo-electric transducers one per string often in combination with small internal microphones to produce a direct output mixed electrical signal.

They are sometimes grouped both spatially ( moving from outside the cell inwards ) and chronologically ( parallelling the " normal " process of signal transduction ).

They release signal molecules into their environment, by which they find each other and create swarms.

They differ by AM or FM sound modulation, signal polarization, relative frequencies within the channel, bandwidth, etc.

They multiplexed the signal across all 8 wires thereby lowering the frequency and making it more robust.

( They are often termed " hot " and " cold ," and the AES14-1992 ( r2004 ) Standard EIA Standard RS-297-A suggest that the pin that carries the positive signal that results from a positive air pressure on a transducer will be deemed ' hot '.

They do this by mixing the television signal frequency, f < sub > CH </ sub > with a local oscillator at a much higher frequency f < sub > LO </ sub >, creating a heterodyne at the sum f < sub > CH </ sub >+ f < sub > LO </ sub >, which is added to the cable.

They exist only to place the signal in the correct state to allow the mid-bit transition.

They can be used to recover a signal from a noisy communication channel, generate stable frequencies at a multiple of an input frequency ( frequency synthesis ), or distribute clock timing pulses in digital logic designs such as microprocessors.

They cannot be bent, twisted, or otherwise shaped without changing their characteristic impedance, causing reflection of the signal back toward the source.
