Over a relatively short period of time, usually about four to twelve weeks, the worker must be able to shift the focus, back and forth, between immediate external stressful exigencies ( `` precipitating stress '' ) and the key, emotionally relevant issues ( `` underlying problem '' ) which are, often in a dramatic preconscious breakthrough, reactivated by the crisis situation, and hence once again amenable to resolution.

Manual leveling is inconvenient if the platform must be maintained accurately level for any prolonged period of time.

But it soon became clear that the search for eighteenth-century furniture ( which Mrs. Kennedy feels is the proper period for the White House ) must be pursued in places other than government storage rooms.

In the specific case of time diffusion, we must emphasize the significance of the earlier development of mistrust when it is combined with the inevitable time crisis experienced by most ( if not all ) adolescents in our society, and with the failure of the adolescent period to provide opportunities for developing trust.

While it must be said that these same Protestants have built some new churches during this period, and that religious population shifts have emptied churches, a principal reason for this phenomenon of redundancy is that fewer Protestants are going to church.

But, in spite of all this, enough evidence remains to show that the magic square of three must indeed have been the object of a rather extensive cult -- or series of cults -- reaching fullest expression in the Han period.

Pentecost then outlines the biblical time period for this campaign to occur and with further arguments concludes that it must take place with the 70th week of Daniel.

To be a blizzard, a snow storm must have sustained winds or frequent gusts that are greater than or equal to with blowing or drifting snow which reduces visibility to 400 meters or a quarter mile or less and must last for a prolonged period of time — typically three hours or more.

Typically, a work must meet minimal standards of originality in order to qualify for copyright, and the copyright expires after a set period of time ( some jurisdictions may allow this to be extended ).

In general, must be renewed periodically, or may be valid for a specific period of time ( e. g., the lifetime of the product upon which the individual is certified ).

That a rational number must have a finite or recurring decimal expansion can be seen to be a consequence of the long division algorithm, in that there are only q-1 possible nonzero remainders on division by q, so that the recurring pattern will have a period less than q.

The discrete input function must also have a limited ( finite ) duration, such as one period of a periodic sequence or a windowed segment of a longer sequence.

However, a particularly powerful piece of equipment — for example, a cloak that renders its wearer invisible for a brief period — may be treated as a Power that the hero must spend their initial element points on.

However the duration of the filter's impulse response, and the number of terms which must be summed for each output value ( according to the above discrete time convolution ) is given by where T is the sampling period of the discrete time system ( N-1 is also termed the order of an FIR filter ).

Powder used for rocketry can use a slower burn rate since it will accelerate the projectile for a much longer period of time, whereas powders for use in weapons such as flintlocks, caplocks or matchlocks need a higher burn rate since they must accelerate the projectile in a much shorter distance.

Just as one does not judge an individual by what he thinks about himself, so one cannot judge such a period of transformation by its consciousness, but, on the contrary, this consciousness must be explained from the contradictions of material life, from the conflict existing between the social forces of production and the relations of production.

Neither food nor bolus insulin must be taken for 4 hours before or during the evaluation period.

The rationale for the differential treatment goes to the heart of the risk a life insurer takes: Old people are likely to die sooner than young people, so the risk of loss ( the insured's death ) is greater in any given period of time and therefore the risk premium must be higher to cover the greater risk.

Certainly one of the most important comments that can be made upon the spiritual and cultural life of any period of Western civilization during the past sixteen or seventeen centuries has to do with the way in which its leaders have read and interpreted the Bible.

If, as Reid says, `` nearly all his poetry was produced when he was not taking opium '', there may be some reason to doubt that he was under its influence in the period from 1896 to 1900 when he was writing the poems to Katie King and making plans for another book of verse.

This, naturally, will be difficult to do since both the archaeological and place-name evidence in this period, with some fortunate exceptions, is insufficient for precise chronological purposes.

And to do this requires first of all the kind of information about people which is provided by the scientists in industrial anthropology and consumer research, who, for example, tell Courtenay that three days is the `` optimum priming period for a closed social circuit to be triggered with a catalytic cue-phrase '' -- which means that an effective propaganda technique is to send an idea into circulation and then three days later reinforce or undermine it.

The 15th Street deposit is not to be confused with the nearby famous Mayflower Hotel cypress swamp on 17th Street reported in The Washington Post, August 2, 1955, which was probably formed during the second interglacial period and is therefore much younger.

In the 10-year period, it is proposed that insect and disease control on the National Forest System be stepped up to a level of prevention, detection, and control of insect and disease infestations that will substantially reduce the occurrence of large infestations toward the end of the initial period.

The objective is to achieve sufficient effectiveness of control on all of the area now under treatment plus the additional acres so that after the initial period only maintenance control will be needed.

Rodent control work for the 10-year period will be aimed at control of the most serious infestations of harmful rodents, such as porcupines and mice, on high-value areas of forage and commercial timberlands.

Approximately 1.8 million acres of rangelands and 9.4 million acres of timberlands would be treated in this period.

Approximately 40 percent of the value of the work on roads for access to timber which are planned for this period will be constructed by purchasers of National Forest timber, but paid for by the Government through adjustment of stumpage prices.
