At higher speeds the pilot simply couldn't move the controls because there was too much airflow over the control surfaces.

At some speeds the airflow over the control surfaces will become turbulent, and the controls will start to flutter.

At present in 2007 the practice of nanotechnology embraces both stochastic approaches ( in which, for example, supramolecular chemistry creates waterproof pants ) and deterministic approaches wherein single molecules ( created by stochastic chemistry ) are manipulated on substrate surfaces ( created by stochastic deposition methods ) by deterministic methods comprising nudging them with STM or AFM probes and causing simple binding or cleavage reactions to occur.

At the high-end, where one is willing to trade-off higher rendering times for increased image quality and precision, smooth surface representations such as Bézier patches, NURBS or Subdivision surfaces are used.

Let the total power radiated from a point source, for example, an omnidirectional isotropic antenna, be P. At large distances from the source ( compared to the size of the source ), this power is distributed over larger and larger spherical surfaces as the distance from the source increases.

At ten or eleven years, used surfaces of the teeth begin to bear a square mark surrounded by a white line, and this is pronounced on all the teeth by the twelfth year ; between the twelfth and the fourteenth year this mark takes a round form.

At lower doses, these include sensory alterations, such as the warping of surfaces, shape suggestibility, and color variations.

At low airspeeds, the control surfaces became ineffective and could readily lead to loss of control, particularly during landing.

At the time, the country had about 2. 2 million miles ( 3. 5 million km ) of rural roads, of which a mere 8. 66 percent ( 190, 476 miles or 306, 541 km ) had " improved " surfaces: gravel, stone, sand-clay, brick, shells, oiled earth, etc.

At dosages adequate for a lung effect there is little risk of absorption through the skin or contact hazards from aerosols that have settled out onto surfaces.

At extreme cosmological distances, the property of mechanical equilibrium in surfaces lateral to the line of sight can be empirically tested ; however, under the assumption of the cosmological principle, it cannot be detected parallel to the line of sight ( see timeline of the universe ).

At the points where the rotor touches the stator, the surfaces are generally traveling transversely, so small areas of sliding contact occur.

At larger sizes, the study of idealized foams is closely linked to the mathematical problems of minimal surfaces and three-dimensional tessellations, also called honeycombs.

At the elevated temperature and pressure conditions chemically reactive constituents of the lubricant react with the contact surface forming a highly resistant tenacious layer, or film on the moving solid surfaces ( boundary film ) which is capable of supporting the load and major wear or breakdown is avoided.

At such low speeds, aircraft flight control surfaces begin to lose their effectiveness.

At first this did not matter too much, as Enriques's intuition was so good that essentially all the results he claimed were in fact correct, and using this more informal style of argument allowed him to produce spectacular results about algebraic surfaces.

At the tips of their pedipalps, Solifugae bear eversible adhesive organs, which they may use to capture flying prey, and which at least some species certainly use for climbing smooth surfaces.

At this point the dilemma surfaces.

At these surfaces they naturally orient themselves with their head groups in water and their tails either sticking up and largely out of water ( as at the air-water interface ) or dissolved in the water-immiscible phase that the water is in contact with ( e. g. as the emulsified oil droplet ).

At this point, the bark on the touching surfaces is gradually abraded away as the trees move in the wind.

At the summit this is overlain by scree and to the south are areas where the underlying Loweswater Formation surfaces.

At millimeter wavelengths, surfaces appear rougher so diffuse reflection increases.

At first, only-partially boosted systems were used in which the pilot could still feel some of the aerodynamic loads on the control surfaces ( feedback ).

At that time there were no milling, planing or shaping machines, and all flat surfaces were made by hand chipping, filing and scraping.

At her door, two or three hours later, Mary Jane whispered, `` Everyone is asleep ''.

At General Power's seat in the balcony there is also a gold phone.

At the same time, he is plainly sympathetic, clearly friendly.

At the same time, because the personal code of the detective coincides with the legal dictates of his society, because he likes to catch criminals, he is in middle class eyes a virtuous man.

At the national and international level, then, what is the highest kind of morality for the private citizen represents an instance of political immorality.

At that point we reach the `` closed '' historical situation: the situation in which man is no longer free to return to a status quo ante.

At the same time, I am aware that my recoil could be interpreted by readers of the tea leaves at the bottom of my psyche as an incestuous sign, since theirs is a science of paradox: if one hates, they say it is because one loves ; ;

At this point a working definition of idea is in order, although our first definition will have to be qualified somewhat as we proceed.

At Sounion there is a group of beautiful columns, the ruins of a temple to Poseidon, of particular interest at that time, as active reconstruction was in progress.

At his press conference Mr. Kennedy said, `` All we want in Laos is peace not war a truly neutral government not a cold war pawn ''.

At the head of the CDC is an unorthodox, 39-year-old amateur politico, Thomas B. Carvey Jr., whose normal profession is helping develop Hughes Aircraft's moon missiles.

At the left is a pair of dressy straw pumps in a light, but crisp texture.

At right is a casual style in a crushed unlined white leather.

At a rate of $3.22 an hour he is now earning approximately $580 a month.

Having hedged its bets in this way, PHS apparently decided it would be possible to make some sort of determination after all: `` At present radiation levels, and even at somewhat higher levels, the additional risk is slight and very few people will be affected ''.

) At this late date, it is impossible for St. Michael's College to find a suitable replacement for me.

At the same time, his voice betrayed uncertainty about their being here, and conveyed an appeal to whatever is reasonable, peace-loving, and dependable in everybody.

`` At least there is room here '', she said.

At the entrance side of the shelter, each roof beam is rested on the inside 4 inches of the block wall.

At that time consideration will be given to whether in the light of the United States supplies of rice available for Title 1, disposal, India's production, consumption and stocks of food grains, other imports from the United States and countries friendly to the United States, India's storage capacity, and other related factors, any increase would be possible in the portion of the total rice programmed which is currently planned for procurement during the first year.

At intervals an alumni directory is issued.

At the recent horse show convention in New York it was stated that this Intermediate Judging Class is meeting with great success and will be a great help to future judges in the horse world.

At the present time the research team which pioneered this new technique is primarily interested in advancing and perfecting it.
